Palletizers are very powerful and they can have many different functions in different environments. For example, a feed palletizer, which can collect, sort and arrange work products. However, due to the popularity of machinery and the growing market demand, the production function and design of palletizers are not the same. Therefore, sometimes the purchase of a palletizer does not know exactly how to choose. Let us explain some of the common problems and hope to help you. 1.Palletizing speed: The working speed of the palletizing machine is to express the efficiency. If the working speed of the palletizing machine cannot reach the production requirement, then the efficiency reduction will affect the production plan of the company. The speed within a certain range is the palletizing machine. One of the basic functions of the expression. 2. The quality of the palletizing machine and the internal structure are the key to the service life and design of the palletizing machine. Good configuration and good component quality are the key to the product. This should be the focus of the company's choice. 3, machine structure: mechanical structure is the design of production requirements, if the design of the palletizer can not meet the production needs, will bring great difficulties, such as grabbed bag palletizing machine, its most important job is The products are automatically collected, sorted, and packed. Therefore, it is necessary to confirm whether the structural design can meet the requirements before purchasing such palletizers, and at the same time meet the requirements for future improvement. 4. System: As with other mechanical devices, the palletizing machine also has a control operating system. This is what most palletizing machines have. In general, the system is a necessary factor for the stable operation of the equipment. If it is powerful, it can be used. Many problems were found in the process and equipment and operation protection could be performed. A good system was also the key to the selection.

With the rapid development of automatic control technology and microcomputers, higher requirements are placed on the positioning accuracy of various types of automatic control systems. In this case, the traditional rotary electric machine is combined with a linear motion driven by a conversion mechanism. The devices can no longer meet the requirements of modern control systems. For this reason, many countries are researching, developing and applying them, making the application of linear motors more and more widely. Linear motors can be considered as a structural variant of rotating electrical machines. It can be seen as a rotating electrical machine along its radial section and then flattened and evolved. What are the advantages of linear motors? The following linear slider manufacturers share a few points for everyone. Compared with rotary motors, linear motors mainly have the following features: 1 The structure is simple, because the linear motor does not need the additional device that turns the rotational motion into the linear motion, thus the structure of the system itself is greatly simplified, and the weight and the volume are greatly reduced. 2 The positioning accuracy is high. In the place where linear motion is needed, the linear motor can realize direct transmission, so it can eliminate various positioning errors brought by intermediate links. Therefore, the positioning accuracy is high. If the microcomputer is used, it can greatly improve the entire System positioning accuracy; 3 fast response, high sensitivity, good follow-up. The linear motor is easily supported by the magnetic levitation of its mover, so that the air gap between the mover and the stator is always maintained without contact, which eliminates the contact friction between the stator and the mover, thereby greatly improving the system. Sensitivity, rapidity and followability; 4 safe and reliable work, long life. The linear motor can realize the non-contact transmission force, and the mechanical friction loss is almost zero, so the failure is less and maintenance-free, so the work is safe and reliable, and the service life is long. These features have led to the main applications of linear motors in the following three areas: 1. Used in automatic control systems, such applications are more; 2. As a long-term continuous operation of the drive motor; 3. Applicable to devices that require a large amount of linear motion energy within a short time and at a short distance.

Linear module is also called the linear motion guide, its application in industry is very broad, many people may not have heard of linear axis, but when it comes to its purpose, may to the precision of automation products you have hearded even used. Let us make a brief introduction of the application of linear guide rail. 1.

A linear actuator moves a load, which can be an assembly, components, or a finished product, in a straight line. It converts energy into a motion or force and can be powered by pressurized fluid or air, as well as electricity. Here is a breakdown of common linear actuators, their advantages and their disadvantages. How They Work 1. Pneumatic linear actuators consist of a piston inside a hollow cylinder. Pressure from an external compressor or manual pump moves the piston inside the cylinder. As pressure increases, the cylinder moves along the axis of the piston, creating a linear force. The piston returns to its original position by either a spring-back force or fluid being supplied to the other side of the piston. 2. Hydraulic linear actuators operate similarly to pneumatic actuators, but an incompressible liquid from a pump rather than pressurized air moves the cylinder. 3. An electric linear actuator converts electrical energy into torque. An electric motor mechanically connected turns a lead screw. A threaded lead or ball nut with corresponding threads that match those of the screw is prevented from rotating with the screw. When the screw rotates, the nut gets driven along the threads. The direction the nut moves depends on which direction the screw rotates and also returns the actuator to its original position. [Pneumatic Actuators] Advantages 1. The benefits of pneumatic actuators come from their simplicity. Most pneumatic aluminum actuators have a maximum pressure rating of 150 psi with bore sizes ranging from ? to 8 in., which translate into approximately 30 to 7,500 lb. of force. Steel actuators have a maximum pressure rating of 250 psi with bore sizes ranging from ? to 14 in., and they generate forces ranging from 50 to 38,465 lbf. 2. Pneumatic actuators generate precise linear motion by providing accuracy, for example, within 0.1 inches and repeatability within .001 inches. 3. Pneumatic actuators typical applications involve areas of extreme temperatures. A typical temperature range is -40°F to 250°F. In terms of safety and inspection, by using air, pneumatic actuators avoid using hazardous materials. They meet explosion protection and machine safety requirements because they create no magnetic interference due to their lack of motors. 4. In recent years, pneumatics has seen many advances in miniaturization, materials, and integration with electronics and condition monitoring. The cost of pneumatic actuators is low compared to other actuators. According to Bimba Manufacturing, for example, the average pneumatic actuator costs $50 to $150. Pneumatic actuators are also lightweight, require minimal maintenance, and have durable components that make pneumatics a cost-effective method of linear motion. Disadvantages 1. Pressure losses and air`s compressibility make pneumatics less efficient than other linear-motion methods. Compressor and air delivery limitations mean that operations at lower pressures will have lower forces and slower speeds. A compressor must run continually operating pressure even if nothing is moving. 2. To be truly efficient, pneumatic actuators must be sized for a specific job. Hence, they cannot be used for other applications. Accurate control and efficiency requires proportional regulators and valves, but this raises the costs and complexity. 3. Even though the air is easily available, it can be contaminated by oil or lubrication, leading to downtime and maintenance. Companies still have to pay for compressed air, making it a consumable, and the compressor and lines are another maintenance issue. [Hydraulic Actuators] Advantages 1. Hydraulic actuators are rugged and suited for high-force applications. They can produce forces 25 times greater than pneumatic cylinders of equal size. They also operate in pressures of up to 4,000 psi. 2. Hydraulic motors have high horsepower-to-weight ratio by 1 to 2 hp/lb greater than a pneumatic motor. 3. A hydraulic actuator can hold force and torque constant without the pump supplying more fluid or pressure due to the incompressibility of fluids 4. Hydraulic actuators can have their pumps and motors located a considerable distance away with minimal loss of power. Disadvantages 1.Hydraulics will leak fluid. Like pneumatic actuators, loss of fluid leads to less efficiency. However, hydraulic fluid leaks lead to cleanliness problems and potential damage to surrounding components and areas. 2. Hydraulic actuators require many companion parts, including a fluid reservoir, motors, pumps, release valves, and heat exchangers, along with noise-reduction equipment. This makes for linear motions systems that are large and difficult to accommodate. [Electrical Actuators] Advantages 1. Electrical actuators offer the highest precision-control positioning. An example of the range of accuracy is +/- 0.000315 in. and a repeatability of less than 0.0000394 in. Their setups are scalable for any purpose or force requirement, and are quiet, smooth, and repeatable. 2. Electric actuators can be networked and reprogrammed quickly. They offer immediate feedback for diagnostics and maintenance. 3. They provide complete control of motion profiles and can include encoders to control velocity, position, torque, and applied force. 4. In terms of noise, they are quieter than pneumatic and hydraulic actuators 5. Because there are no fluids leaks, environmental hazards are eliminated. Disadvantages 1.The initial unit cost of an electrical actuator is higher than that of pneumatic and hydraulic actuators. According to the example from Bimba Manufacturing, an electrical actuator can range from $150 to greater than $2,000 depending on its design and electronics. 2.Electrical actuators are not suited for all environments, unlike pneumatic actuators, which are safe in hazardous and flammable areas 3.A continuously running motor will overheat, increasing wear and tear on the reduction gear. The motor can also be large and create installation problems. 4.The motor chosen locks in the actuator`s force, thrust, and speed limits to a fixed setting. If a different set of values for force, thrust, and speed are desired, the motor must be changed.

China's economy has developed rapidly in recent years, China's robot automated production line equipment market, although the start time is not long, is in the transition from traditional equipment to advanced manufacturing equipment. Nowadays, industrial automation has become an inevitable trend in the development of China's manufacturing industry. With the rise of domestic large-volume fully automated palletizing production lines, palletizing systems will have more extensive market prospects and development potential. In recent years, the cost of labor in the coastal areas of China has continuously risen, which has increased the operating costs of processing and manufacturing companies. The problem of recruitment difficulties has appeared in the coastal areas. In order to ease the pressure on labor costs, more and more companies have chosen to invest in the introduction of robots and gradually replace the traditional labor force. In addition, with the continuous development of logistics, food, and petrochemical industries, palletizing robots are playing an increasingly important role. They can not only accurately and efficiently complete palletizing operations, but also reduce the labor intensity of workers and improve product quality. The palletizing robot is a 4-axis robot. The four motion axes correspond to the X-axis, Y-axis, and Z-axis in a Cartesian coordinate system, and one rotation axis on the Z-axis. There are many advantages of palletizing robots. There are several points to summarize: First, the structure is simple, there are few parts, and the failure rate is low. Second, the area is small. It is beneficial to the layout of the production line in the customer's factory, and can leave a larger area of the warehouse. The palletizing robot can be set in a narrow space for efficient use. Third, the applicability is strong. When the size, volume, shape of the customer's product and the external dimensions of the tray are changed, only a slight modification on the touch screen is needed, which will not affect the normal production of the customer. The mechanical cumbersome change of the palletizer is even impossible to achieve. Fourth, low energy consumption. Usually, the power of a mechanical palletizer is about 26KW, and the power of a palletizing robot is about 5KW. Greatly reduce the customer's operating costs. Fifth, all controls can be operated on the control cabinet screen, and the operation is very simple. Sixth, only by grasping the starting point and placement point, the teaching method is simple and easy to understand.

The rectangular coordinates of the robot's classification: 1, according to the use of points: welding robots, palletizing robots, glue (dispensing) robots, detection (monitoring) robots, sorting (classification) robots, assembly robots, EOD robots, medical robots, special robots, etc. 2, according to the structural form points: wall-mounted (cantilever) robot, gantry robot, upside down robot and other typical rectangular robot. 3, according to degrees of freedom: two-coordinate robots, three-coordinate robots, four-coordinate robots, five-coordinate robots, six-coordinate robots. Cartesian coordinate robot core components - linear positioning unit In order to reduce the cost of Cartesian robots, shorten the product development cycle, increase product reliability, improve product performance, in many countries in Europe and America have been the rectangular coordinate robot modular, The linear positioning unit (system) is the most typical product of modularization. A complete positioning unit (system) consists of several parts 1, Positioning body profile: As the mounting support part of the track, this profile is different from the general frame profile, it requires a very high straightness, flatness. 2, movement track: installed on the positioning body profile, directly support the movement of the slider. A positioning body profile (system) may be installed with a movement track, or it may be installed with a plurality of movement tracks. The characteristics and quantity of the track directly affect the mechanical characteristics of the positioning unit (system). The types of tracks that make up the positioning system are very common. There are linear ball bearings and straight cylindrical steel bearings. 3, movement slider: consists of load mounting plate, bearing frame, roller group (ball group), dust brush, lubrication cavity, sealing cover. The motion sliders are coupled with the rails by rollers or balls. Achieve the guidance of sports. 4, transmission components: General transmission components are synchronous belt, toothed belt, screw / ball screw, rack, linear motor and so on. 7, bearing and bearing seat: used to install the transmission element and drive element. Cartesian Coordinate Robot Drive Elements - Motor Drive System The linear positioning unit (system) is able to achieve precise motion positioning, which is determined by the motor drive system. Commonly used drive systems are: AC/branch servo motor drive system, stepper motor drive system, linear servo motor/linear stepper motor drive system. Each drive system consists of a motor and a driver. The function of the driver is to amplify the weak signal and load it on the strong electric motor to drive the motor. The motor converts electrical signals to precise speed and angular displacement. In the occasions requiring high dynamics, high-speed operation, high-power drive and other occasions, AC/branch servo motor system is used as the drive; in the requirements of low dynamic, low-speed operation, low-power drive and other occasions, stepper motor system can be used as the drive; Very high dynamics, high speed operation, high positioning accuracy and other occasions will use linear servo drive. Cartesian coordinate robot control In order to realize the robot's flexible and varied motion function and rapid response processing function, the robot must have a brain-control system. The function of the control system is to issue motion instructions, process data, determine motion, etc. It can issue control instructions, receive feedback signals, and determine the processing information at any time according to the numbered program. Depending on the work situation, the control system can take many different forms: 1. Combination of IPC and motion control card: The motion control card borrows computer resources and uses its own motion control function to achieve control. 2, offline motion control card: Borrow the computer to make the program, can store the program itself, run offline. 3, PLC - borrow a computer to compile a program, the program can be stored, run offline. 4, dedicated controller. With that kind of control system, the motion control engineer will choose according to the actual situation depending on the situation of the sport and the conditions of use. Cartesian robot terminal equipment - operating tools Cartesian coordinates The terminal equipment of the robot should use different, can be equipped with a variety of operating tools: For example, a welding robot's terminal operation tool is a welding torch: a palletizing robot terminal operation tool is a gripper; a glue (dispensing) robot terminal operation tool is a glue gun, a detection (monitoring) robot terminal operation tool is a camera or a laser. Some work-intensive tasks cannot be completed with a single operating tool. It is necessary to install two or more operating tools. For example, in addition to the need for a mechanical gripper, a camera is also required for the capture of a non-stationary moving object, which constantly tracks the spatial position of the calculated object.

Cartesian coordinate robot concept: In industrial applications, it can realize automatic control, reprogrammable, multi-functional, multi-degree of freedom, right-angle space between movement freedom, multi-purpose operation machine. He can carry objects and operate tools to complete various tasks. With regard to the definition of the robot, with the continuous development of science and technology, it is continuously improving. The Cartesian coordinate robot is a kind of robot and its meaning is constantly being improved. Characteristics of Cartesian Robots: 1, multi-degrees of freedom movement, the angle of space between each degree of freedom of movement is a right angle. 2, Automatic control, repeatable programming, all movements are run according to the program. 3, generally consists of control systems, drive systems, mechanical systems, operating tools and other components. 4, flexible, multi-function, because the different functions of the operating tools are also different. 5, high reliability, high speed, high precision. 6, can be used for harsh environments, long-term work, easy operation and maintenance. Cartesian Robot Application: Due to the different end-effect tools, Cartesian robots can be easily used as a variety of automation equipment to complete such tasks as welding, handling, loading and unloading, packaging, palletizing, demolition, inspection, inspection, classification, assembly, labeling, and spraying. Code, code, (soft copy) spray, target follow, explosive and a series of work. It is especially suitable for flexible operation of many varieties and batches. It plays a very important role in stabilizing, improving product quality, increasing labor productivity, and improving labor conditions and rapid product replacement.

Can according to customer demand for rapid customization, save space and space, which can be widely used in food, beverage, garments, light industry, medicine, electricity and other industries of warehousing logistics sorting process.

The linear bearing is a very important part of the linear guide. It is a linear motion system that is produced at a low cost and is used for infinite strokes in conjunction with cylindrical shafts. Because the bearing ball is in point contact with the shaft, the use load is small. The steel ball rotates with a small frictional resistance so that a high-precision smooth motion can be obtained. Like ball screws, linear bearings are widely used in electronic equipment, tensile testing machines and digital three-dimensional coordinate measuring equipment and other precision equipment, and multi-axis machine tools, punch presses, tool grinding machines, automatic gas cutting machines, printers, card sorters, food packaging Machines and other industrial machinery sliding parts, the use is very wide, but also very practical. A lot of driving methods can generally use servo motor stepper motor, but also useful rotary cylinder, the rotation movement is converted to parallel movement.Standard linear guides and adjustable linear bearings can be distinguished in appearance. The standard linear bearing has a cylindrical shape, and the adjustment type has a small groove on it to adjust the inner diameter. And can be arbitrarily changed its size through technical means.

Ball screw nut pair is only used to bear the axial load, radial force, bending moment will make the ball screw nut auxiliary surface contact stress and other loads, which may cause permanent damage to the screw. Correct installation is a prerequisite for effective maintenance. Therefore, the following points should be noted when installing the ball screw nut assembly into the machine tool: 1) The axis of the screw must be parallel to the axis of the matched guide rail. The bearing seat and nut seat at both ends of the machine must be in line at three points. 2) Mount the nut as close as possible to the support bearing. 3) Install the support bearing as close to the nut installation as possible. 4) When installing the ball screw into the machine, do not remove the nut from the screw. If you must remove the auxiliary sleeve, otherwise the ball may fall off during loading and unloading. When handling nuts, note the following points: (1) The auxiliary sleeve outer diameter should be smaller than the bottom diameter of the screw 0.1-0.2mm. (2) The auxiliary sleeve must be tightly threaded around the threaded shaft shoulder during use. (3) When unloading, do not use too much force to avoid damage to the nuts. (4) Avoid impact and eccentricity when installing the mounting hole. How to install the ball screw nut ball method? First of all, users are not recommended to disassemble and install nuts themselves, especially high-precision ball screws. If the nut accidentally falls off or you have now disassembled, please reinstall the nut by following the following method: Make an outside diameter slightly smaller than the bottom diameter of the screw raceway (smaller than 0.1mm), and the inside diameter is slightly larger than the outside diameter of the screw end (Large 0.5~2mm) Hollow sleeves with a length longer than the nut length (10~50mm long).

What is the linear guide of a metal laser cutting machine? Many people are concerned about this issue. What is the purpose of the linear guide of a metal laser cutting machine? What does it play in the production and processing of metal laser cutting machines? What kind of role? Let's look at it together. For the metal laser cutting machine, its linear guide is a tool for linear reciprocating motion. This tool has a higher rated load than previous linear bearings do, and it can also take up a certain amount of torque. It is also possible to achieve high-precision straight-line motion in the case of high loads. The linear guide is also an integral part of the laser cutting machine. The linear guide of the metal laser cutting machine is in need of regular maintenance. We must first move the laser cutting head to the right end or the left end, then find the linear guide we need to find, and then gently wipe the surface with a cotton cloth Until it is clean and clean, then add a little oil to it and push the laser head slowly to the left and right several times to distribute the oil evenly. The linear guide and linear axis above the laser cutting machine are one of the core components of the laser cutting machine. Its function is guiding and supporting. In order to ensure that the machine has a high processing accuracy, we require its guide rails and straight lines to have high guiding accuracy and good movement stability. The guide of the laser cutting machine should be cleaned once a month. It must be operated under the condition of shutting down. Dry cotton cloth and lubricating oil must be prepared in advance before cleaning.

High-speed machining is a high-paying technology oriented to the 21st century. It is characterized by high efficiency, high precision, and surface quality. It has become increasingly popular in aerospace, automotive, tooling, optoelectronic engineering, and instrumentation. The application, and has achieved significant technical and economic benefits, is an important part of contemporary advanced manufacturing technology. In order to achieve high-speed machining, high-speed CNC machine tools are first required. High-speed CNC machine tools must have both a high-speed spindle system and a high-speed feed system to achieve high-speed material cutting. In order to realize high-speed feed, manufacturers at home and abroad have continuously taken measures to improve the high-speed performance of the ball screw. The main measures are: Appropriately increase the screw speed, lead and thread number. At present, the matching of the nominal lead diameter and lead of a large-lead ball screw is: 400mm*20mm, 50mm*25mm, 50mm*30mm, etc., and the feed rate can reach 60m/min or more. In order to improve the rigidity and load-carrying capacity of the ball screw, the large-lead ball screw generally adopts double-headed threads to increase the number of effective bearing cycles of the ball. Improve the structure and improve the smoothness of ball movement. Improve the ball circulation reversal device, optimize the curve parameters of the return ball groove, adopt the three-dimensional shape of the guide tube and the return ball device, truly introduce the ball into the nut body along the lead angle of the internal thread, so that the ball moves The direction is tangent to the raceway rather than intersecting. This minimizes shock losses and noise. Further improve the manufacturing quality of ball screw. By adopting the above measures, some problems in the transmission ball screw can be overcome to some extent. Its maximum fast moving speed can reach 60m/min, and in some cases it can even reach 90m/min and the acceleration can reach 15m/s2. Because the ball screw has a long history, mature technology, wide application, and low cost, it is still not very high in the middle load bearing, the feed rate is not very high, the general high-speed machining center and other economical high-speed CNC machine tools whose travel range is not too large are still Often used.

The selection of the screw linear module can be based on the following parameters: (1) The load, that is, the weight of the screw linear module required to load the object; (2) Operational speed requirements; (3) Motion accuracy requirements. Motion accuracy generally refers to the accuracy of the repetitive motion of the screw rod, that is, the distance between the lead screw module and the original point after returning to the end after 30 rounds of reciprocation; (4) Demand for effective itinerary. That is, how long the interval from one end to the other needs to travel; In addition to selecting the straight screw module based on the performance, consider the following requirements: Correspondingly, when selecting the screw linear module, first determine the detailed parameters of the screw linear module according to the above requirements: (1) In the practical use of the module, the demand for loads of multiple objects, demand practice calculations. When the load component is greater than 15KG, linear modules are recommended. (2) Practically selected modules, the effective travel requirement is about 50mm more than that of practice, so as to reserve expanded space expansion (3) Use Different modules have different requirements for motion accuracy. FUYU Technology - Ultra High Speed, High Accuracy, Long Stroke Linear Module Leader.

The linear module is widely used in the automation industry. It is relatively different in the development of different automation industries. Then when choosing a linear module, consider various factors. The following are the major factors that need to be assessed. 1. Vibration resistance and stability: Stability refers to the performance of self-excited vibration under a given operating condition, and vibration resistance refers to the ability of a module to receive forced vibration and impact. 2. Stiffness is particularly important for precision machinery and instruments. The deformation of the module includes deformation of the guide rail body and deformation of the guide rail, and the ability of the guide rail to resist deformation by force. Deformation will affect the relative position and guidance accuracy between components. Both should be considered. 3. Motion Sensitivity and Positioning Accuracy The linear guide motion sensitivity refers to the minimum stroke that the moving member can achieve. Positioning accuracy refers to the ability of the moving member to stop at a specified position as required. Motion sensitivity and positioning accuracy are related to the type of guide rail, friction characteristics, movement speed, transmission stiffness, and quality of moving components. 4. The accuracy of adherence: refers to the ability to maintain the original geometric accuracy during the work process. The accuracy of the module depends mainly on the wear resistance of the guide rail is extremely dimensional stability. The wear resistance is related to the data matching of the guide rail pair, the force, the processing precision, the lubrication method and the performance of the protective device. The residual stress in the guide rail and its support also affects the accuracy of the guide rail. 5. Guide precision and thermal deformation of the module and support. Guide accuracy refers to the exact level of motion of the moving member as it moves along the guide surface of the guide rail. The main factors influencing the guiding accuracy are the geometric accuracy of the bearing surface of the guide rail, the structure type of the guide rail, the contact accuracy of the guide rail pair, the appearance roughness, the rigidity of the guide rail and the support element, the thickness of the oil film of the guide rail, and the oil film rigidity. The geometric accuracy of linear motion guides generally includes: the straightness in the vertical plane and the horizontal plane; the parallelism between the two guide surfaces. The geometrical accuracy of the rails can be represented by the error in the overall length of the rail or the error in the unit length. 6. Movement Stability The stability of the module is the performance of the track that does not appear to crawl when it moves at a low speed or in a small amount. The stability is related to the structure of the guide rail, the matching of the guide rail auxiliary materials, the lubrication condition, the lubricant properties, and the stiffness of the drive system of the guide rail motion.

As an important part of the precision engraving machine, the screw rod will fail. Do you know? How do we solve these problems? The ball screw of the CNC engraving machine is composed of a screw, a nut and a ball. It converts the rotary motion into a linear motion, or converts the linear motion into an ideal transmission element for a rotary motion! Due to the small frictional resistance, ball screws are commonly used in various industrial equipment and precision instruments. However, there are still some problems encountered in use. Failure to deal with them will cause malfunctions, which will affect the precision of the engraving machine and even cause the machine to stop working. Then, Hao Dabian told everyone about some of the common fault diagnosis methods of screw and what to pay attention to when using it. First, common faults and corresponding diagnostic exclusion methods are described below. 1. Failure caused by improper control of preload when adjusting axial clearance The double nut type ball screw nut can basically eliminate the axial clearance after being adjusted by the preload. However, the size of the pre-tightening force should be controlled at this time. If the pre-tightening force is too small, the axial clearance cannot be completely eliminated and the pre-tightening effect will not be achieved; if the pre-tightening force is too large, the no-load moment will increase, thereby reducing the transmission efficiency and causing the drive motor to generate heat and overloading. Call the police. The way to eliminate such failures is to readjust the pre-tightening force as required so that it can eliminate the gap and make the pre-tightening force too little. 2, due to ball screw failure caused by self-locking The ball screw nut has a low coefficient of friction and high transmission efficiency, but it cannot be self-locking. Therefore, when the ball screw nut is used for high-speed large-scale inertia transmission of vertical transmission or horizontal placement, the headstock is prevented from slipping or overshooting due to sudden power failure. Braking devices must be considered in the transmission chain. Otherwise, abnormal faults may occur due to the inertial movement of the moving parts due to their own weight. Severe damage to machine tool components may occur. Common braking methods include the use of overrunning clutches, electromagnetic friction clutches, or the use of servo-driven motors with braking devices. 3, ball screw nut noise in the transmission process The ball screw nut is a high-precision transmission element. The main cause of noise in the work is that there is a certain defect in the process of assembly and adjustment, or the daily inspection and maintenance are not in place. If the fasteners loosen, the bearing glands are not in place, and the bearing or the feed screw nut is damaged and poorly lubricated. In order to reduce the occurrence of such failures, it is usually necessary to strengthen the daily inspection and maintenance of the feed transmission chain, and timely tighten the loose parts. Through the inspection of the processed parts, the feed chain is adjusted in time to check whether the lubrication system is smooth. Second, the ball screw screw is a precision component, should pay attention to the following points when using. (1) Before use, check the lubrication condition. If the lubrication is not good, the function of the ball screw will be lost in the short term. (2) When using grease, please use it directly. However, during use, if there is dust or dust on the surface of the grease, clean it with clean white kerosene, and then reapply it with a new grease that is the same as the original grease. Mixing of different types of grease should be avoided. (3) The inspection as a lubricant is to be put into use for 2 to 3 months. When it is found that the dirt is more noticeable, it is recommended that the old lubricant on the product be wiped clean and re-applied with a new lubricant. After that, the grease inspection cycle and the lubricant replacement cycle are regularly performed. Generally, it is 1 year. However, set the appropriate interval according to the environment.

In the production of linear module, the linear guide steel ball burst occasionally. For linear module encountered during the installation process of linear guide, how to solve the problem of blowing steel ball, just read the following introduction. 1. Walking after a period of time, the slide block found deformation or fracture dustproof cover and end.Installation error will make the slider and the track, only unilateral stress between may also be affected by the external force caused by dust cover and end deformation or fracture. Prevention advice: a. The slider inside Solution: change the dust control system, improve the lubricating oil, increase the amount of lubricating oil, reduce the lubrication time interval. b. No suitable working parameters Solution: technology calculation verification, optimization of product configuration and installation Angle. c. Load misjudgment and the slide block number is not correct Solution: the optimization of product configuration. 2. Use after a period of time, found indentation and the slider rail track ball is broken, and what reason is this? Main reason in the overload, steel ball from orbit, steel ball rupture caused by orbit were damaged. Prevention advice: a. The rated at the end of life Solution: replace the new. b. The overload Solution: use large sliding block, and increase the quantity of the slider, reduce the external load, improve the installation technique, reduce unilateral stress distribution. c. The lubrication Solution: increase the amount of lubricating oil, shortening the lubrication time interval. d. A foreign matter Solution: to improve the sealing parts, take the dustproof side.

As we all know, there are only two types of commonly used linear actuator: Belt driven linear module, also known as synchronous belt; Ball screw linear actuator, they are also called ball screw linear motion guide. Linear module in some industry fileds, is also named cartesian robot, of course, a single line module can not be called rectangular coordinate robot, only for more than a shaft platform under the condition of linear module. Special to note is that the internal screw module is mainly composed of linear guide rail, slider, ball screw and the installation of some related links, external is aluminum, also is what we call the ontology, and external aluminum plate, to go motor of screw module. Aluminum body with high properties, coupled with the standard ball screw, linear guide rail of high precision, high speed linear module, this modular components assembly relative customer own design will be more convenient, also don't need professional installation and maintenance. The basic features of the ball screw module: 1. Ever axis under the long-term use can keep stable accuracy. 2. Universal precision can reach at least 0.04-0.05mm (We supply C7 precision which can achieve 0.01-0.02mm). 3. Whether stepper or servo matchs on the linear module can be used. 4. According to the direction of the use and load capacity stroke is decided. On the positioning accuracy, belt driven linear module is lightly worse than ball screw actuator, of course, the price is relatively lower, suitable for packaging machinery, printing machinery, logistics handling, lithium battery transplanting handling low precision requirement of automation industry, such as belt with steel wire inside, in order to make the leather belt is more durable, belt module is through the width of the belt to increase the load capacity of module, compared with screw module, belt module relatively faster speed, light fast positioning, belt module is not recommended for Z axis. The basic features of the belt driven actuator: 1. Low noise, small size and light weight. 2. Easy to change the main components. 3. The stroke of belt driven linear module can be super-long for customer`s design. Anyway, belt driven linear module is quicker than ball screw linear actuator, no critical speed limit at the same time, with more than the other in terms of long stroke transmission ratio, but the positioning accuracy of synchronous belt transmission is lower than the ball screw linear motion guide.

In the production of linear module and synchronous belt, we often use guide rail, which in linear module and synchronous belt is indispensable parts. Because of the influence of the external environment, the formation of them can be simply corrosied, rust after the guideway affects mechanical properties, so we want to maintain it for the better preference. 1. Linear guide material is made of steel, linear guide is used to support and guide the movement of the parts, because it is so steel will also have a rusty phenomenon, for this kind of problem in the case of linear guide does not use try not to tear up the packaging and also to pay attention to when using hand sweat, hands sweat too much people in contact with linear guide should wash your hands first hand last year when sweat, when installed in a straight line module should also be appropriate to add some lubricating oil. 2. Manufacturer of linear module knows linear guide to buy back, it is has a layer of oil, the oil is in order to prevent linear guide rusty, but in order to better ensure that without rust need to go to for a long time to maintain, it is best to choose the appearance of about 2 months to linear guide to refuel, if use no oil it didn't take long, should be more to add, linear guide but no oil is easy to rust, so people should pay more attention to this situation. 3. The deposit environment also should pay attention to is not profit under wet storage, storage interface not good on the floor, as far as possible on the board or other mesa, depositing surface should be smooth, so the environment is part of the key factor.

With the rapid development of industrial automation, the application of Cartesian coordinate robots is more and more widely used, but the accuracy needs to be higher in specific applications.The rectangular coordinate manipulator is composed of multi-axis XYZ linear modules. When the structural rigidity and contact stiffness of the three-axis manipulator itself are low, the vibration is easily generated and the positioning accuracy is generally low. Then how to operate to ensure its stability and accuracy? 1. First of all look at the accuracy of the uniaxial linear module, its stability and accuracy are maintained by: a. Accuracy grades of screw, guide rail, supporting seat and bearing of the main parts of the product; b. The degree of parallelism between the screw rod and the guide rail when assembling, and the guarantee of the concentricity between the screw rod and the bearing; 2. The accuracy of multi-axis combination depends on: a. Multi-axis robot mounting platform rigidity and flatness; b. Assembled precision assurance equipment and professional technical requirements and process requirements; c. Positioning speed: The positioning speed has a great influence on the positioning accuracy. This is because when the positioning speed is different, the energy of the moving parts that must be dissipated is different. Generally, in order to reduce the positioning error, the positioning speed should be reasonably controlled, such as increasing the buffering performance and buffering efficiency of the buffer device, and controlling the drive system to decelerate the moving parts in a timely manner. d. Weight of the endless workpiece: When the weight of the moving part increases, the positioning accuracy decreases. Therefore, the design must not only reduce the weight of the moving parts themselves, but also take into account the impact of changing the weight of the work. e. Drive source: The pressure fluctuation of hydraulic pressure and air pressure, and the fluctuation of voltage, oil temperature and air temperature all affect the repeatability of the manipulator. Therefore, the necessary regulation and adjustment of the oil temperature are adopted. If the accumulator is used to stabilize the oil pressure, the heater or cooler is used to control the oil temperature. When the speed is low, the temperature and pressure compensation flow control valve is used for control. f. Control system: The position control accuracy of switch control, electro-hydraulic proportional control and servo control is different. This is not only because the accuracy and sensitivity of various control elements are different, but also related to the presence or absence of position feedback devices.

There are semi-closed and fully-closed points in the linear module, but what is the difference between the semi-enclosed linear module and the fully enclosed linear module? 1) Different structure The totally enclosed linear module is to seal the transmission part inside and prevent the dust from falling on the transmission part. The semi-enclosed linear module has a mouth on both sides. This mouth is open to the mover seat, and the transmission member can be seen through the mouth. 2) The use of different environments The semi-enclosed linear module is mainly suitable for dust-free working environment. The totally enclosed linear module is used in dusty environment, mainly because the dust will affect the life of the linear module. For example, some dusty environments use semi-closed straight lines. Modules, dust is easy to enter, dust stuck to the screw, if you do not clean up will affect the operation of the screw, but if you often need to remove the cleaning, this is a waste of time, so the general more dust working environment Select a fully enclosed linear module. 3) Different costs Fully enclosed linear module is relatively high compared to semi-closed, and its profile is also not the same. Semi-closed is a concave shape, full closed is a bit like a mouth shape, just the place of the upper mouth A groove is opened. This groove is used for a movable seat, and then a steel wire belt is placed on the movable seat. It also has a dust cover. It is harder to install the fully enclosed linear module than the semi-closed linear module in terms of assembly. One point, so these are the reasons that indirectly cause higher costs. In short, which module to purchase is more suitable for the enterprise, depending on the specific working environment and the user's assembly technology level.
