Description

Technical Field

[0001] The present invention relates to the technical field of electronic product manufacturing, and in particular to an electronic product automatic assembly robot. Background Art

[0002] The application of automated assembly robots is crucial in the electronics manufacturing sector. While existing technologies can achieve basic automated assembly, they suffer from numerous limitations. First, existing robots struggle to effectively eliminate static electricity from PCBs, which can damage sensitive components and reduce product quality. Second, their limited adaptability to PCBs and components of varying sizes limits the robots' versatility and flexibility. Furthermore, their assembly precision is low, making it difficult to meet the demands of high-density, high-precision electronics. Furthermore, existing robots suffer from low assembly efficiency and long periods of non-productive time, impacting overall production efficiency. Finally, existing robots have limited functionality, making them incapable of meeting the complex and ever-changing demands of electronics assembly, limiting their application in high-end electronics manufacturing.

[0003] In summary, the existing technology has obvious deficiencies in static elimination, adaptability, assembly accuracy, efficiency and functionality. There is an urgent need for a more efficient, flexible and precise electronic product automatic assembly robot to overcome these defects and improve the level of electronic product manufacturing. Summary of the Invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an automatic assembly robot for electronic products.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A robot for automatic assembly of electronic products comprises an electrostatic removal unit, an auxiliary unit and an assembly mechanism, wherein the auxiliary unit is installed on the upper end face of the electrostatic removal unit, and the assembly mechanism is installed laterally on one side of the auxiliary unit, and the assembly mechanism comprises a positioning cross frame installed laterally on the side end face of the auxiliary unit, and the side end face of the positioning cross frame is installed laterally on the mounting frame, a first edge clamp is installed on both sides of the outer end wall of the mounting frame, a second edge clamp is installed on both sides of the outer end face of the first edge clamp, a moving part is slidably installed on the bottom of the first edge clamp and the second edge clamp, an adjustment mechanism is fixedly installed on the top of the mounting frame, and a clamping push cross bar is installed on the side of the mounting frame, the first edge clamp and the second edge clamp close to the positioning cross frame.

[0006] Preferably, the movable member can move back and forth along the path of the lower end surfaces of the first edge clamp and the second edge clamp, clamping the end surfaces of both sides of the PCB board to be processed at the interval between the first edge clamp or the second edge clamp, and the two groups of movable members arranged laterally are connected to each other by a transverse connector. The movable member is installed at the bottom of the first edge clamp and the second edge clamp of the component and can move back and forth along its lower end surface. This moving function enables the robot to adjust its position in the horizontal direction so that the electronic components can be accurately placed in the predetermined position. For example, the PCB board is placed laterally at the interval between the second edge clamp, and the transverse connector is driven by the transverse reciprocating movement of the movable member, so that components such as resistors and capacitors can be accurately placed in the specified position on the board. PCB boards of different sizes may require components to be installed at different positions. The reciprocating movement function of the movable member can adjust its range of movement to adapt to PCB boards of different sizes, ensuring that all areas that need to be assembled can be covered.

[0007] The reciprocating motion of the moving parts enables the robot to quickly move to the next assembly position after completing the assembly of one component to assemble the next component. This continuous operation improves assembly efficiency and reduces non-productive time.

[0008] The movement of the moving part can be combined with the rotation or telescopic function of the component adjustment mechanism to achieve more complex assembly tasks. For example, when installing a component that requires a specific angle or depth, the moving part can be moved to the appropriate position.

[0009] When a moving part needs to move to a target position at high speed and then stop quickly, its own inertia can assist in positioning. For example, during high-speed placement, the moving part moves components to a specified location on a PCB at high speed. As it approaches the target position, the motor gradually decelerates, allowing the moving part's inertia to continue moving a short distance until it stops at the precise location. This inertia-assisted positioning can reduce minor positional deviations caused by sudden motor braking and improve positioning accuracy.

[0010] In assembly tasks that require frequent starts and stops, the inertia of moving parts can aid positioning. For example, when assembling multiple components on a circuit board, a moving part must quickly move and stop between each component position. Leveraging inertia, the moving part can more accurately stop at the target position at each stop, reducing jitter and positional deviation caused by the motor's frequent starts and stops.

[0011] Preferably, an adjustment mechanism is installed horizontally at the top position of the first edge clamp, and the adjustment mechanism includes a horizontal mounting member and a first driving wheel installed at the middle position of the bottom of the horizontal mounting member. The outer ring of the first driving wheel is sleeved with a driving rope, and the other end of the driving rope is sleeved on the outer ring of the second driving wheel. The bottom of the second driving wheel is installed vertically downward on the upper end face of the static removal unit. The material and length of the driving rope are changed according to different needs, so that the adjustment mechanism as a whole can be adjusted in length on the upper end faces of the mounting frame, the first edge clamp and the second edge clamp. Under the overall drive of the adjustment mechanism, the side end face of the horizontal mounting member is pushed laterally to the electronic component to be installed, thereby pushing the electronic component to the preset position.

[0012] The driving rope can be replaced with rubber material, which has excellent elasticity, can buffer and reduce shock, protect the robot and components from damage, and has good sealing performance to prevent dust and liquid intrusion. It is suitable for assembly environments with shock absorption and protection requirements.

[0013] The driving rope can be replaced with carbon fiber composite materials, which are high in strength and lightweight, with excellent fatigue resistance and corrosion resistance. They can reduce weight while maintaining component strength and are suitable for the assembly of high-end electronic products.

[0014] The shorter drive rope provides higher rigidity and stability, reduces bending and deformation during movement, ensures accuracy and reliability, and reduces motion inertia, making it suitable for assembly tasks requiring precise positioning and high rigidity.

[0015] The longer driving rope provides a larger range of motion and flexibility, adapts to complex assembly paths and multi-position operations, increases the robot's workspace, and is suitable for tasks that require assembly operations in a larger space.

[0016] Preferably, the assembly mechanism also includes an adapter mechanism installed at the bottom position of the mounting frame and the clamping and pushing cross bar, the adapter mechanism includes a vertical piece and connecting pieces installed horizontally on both side end faces of the vertical piece, the lower end face of the connecting piece is horizontally installed with a horizontal assembly piece, and swing pieces are vertically arranged at both sides of the edge of the horizontal assembly piece, and a connecting support tube is installed on the front end face of the swing piece, and friction wheels are horizontally inserted through the bottom of the vertical piece and the swing piece, and the bottom of the friction wheel is affixed to the top of the static removal unit and the side end face of the clamping and pushing cross bar is affixed to the top of the PCB board to be installed, so that the electronic components to be pushed can be moved to the correct position, and the adapter mechanism as a whole can be driven to move in the same direction during its movement, because the horizontal assembly piece and the swing piece can swing back and forth with the connecting support tube as the fulcrum, and the friction wheels at different positions are used to effectively push the electronic components of the PCB board.

[0017] When the clamping pushes the crossbar to move, the friction wheel at the bottom of the vertical part moves driven by it, and the friction wheel at the bottom of the swinging part is pulled laterally under the drive of the lateral driving force. At this time, the friction wheel at the bottom of the swinging part can perform static friction on the upper end surface of the PCB board. When the static friction force pushes the component, it produces a slight clamping effect, which makes the component remain stable during the movement, avoids damage to the component due to accidental collision or vibration, and improves the integrity of the component. The static friction force can automatically adjust its force according to the slight undulations and unevenness of the PCB board surface, enhancing the robot's adaptability to different PCB board conditions, just like installing an "adaptive module" on the robot.

[0018] When the vertical member reciprocates with the side end surface of the clamping and pushing cross bar as the fulcrum, the outer end wall of the friction wheel contacts the upper end surface of the PCB board, and during the following movement of the friction wheel at the bottom of the swinging member, the swinging member is offset and swung at both ends of the horizontal assembly with the connecting support tube as the fulcrum, so that the outer end surface of the friction wheel slides and rubs against the upper end surface of the PCB board.

[0019] The sliding friction between the friction wheel and the upper surface of the PCB acts as a shock absorber, like an unexpected "shock pad" for the entire assembly system, reducing errors caused by vibration during assembly. The contact between the friction wheel and the upper surface of the PCB provides a stabilizing force. This stabilizing force prevents the PCB from accidentally sliding, keeping the entire assembly platform stable under slight vibrations or collisions. It acts as an unexpected "stabilizer" for the entire system and can also propel the electronic components located inside the friction wheel to move horizontally to the correct position.

[0020] Preferably, the auxiliary unit includes a mounting bracket and sleeves mounted on both sides of the side end surface of the mounting bracket, the outer ring of the mounting bracket is sleeved with a protective cover, and the inner cavity of the sleeve is interspersed with a telescopic pushing mechanism.

[0021] Preferably, the telescopic pushing mechanism includes an insert and a telescopic rod mounted at one end of the insert. The insert is movably connected to the pushing frame via the telescopic rod. An arranging member is disposed transversely on the lower end surface of the pushing frame, and the insert is laterally inserted into the inner cavity of the socket. Driven by an external motor, the arranging member telescopes and adjusts with the telescopic rod as a fulcrum, so that the arranging member, driven by the pushing frame, pushes electronic components on a PCB placed on the upper end surface of the receiving table. The arranging members are arranged transversely, and this arrangement enables the arranging members to push the electronic components in a transverse direction, adapting to the horizontal layout of components on the PCB.

[0022] Preferably, the static electricity removal unit includes an static electricity treatment box and a contact inner chamber opened in the inner cavity of the static electricity treatment box, a bottom opening hole is opened on one side of the bottom position of the contact inner chamber, an edge bracket is installed at the edge position of the static electricity treatment box, a rotating motor is opened in the inner cavity of the edge bracket, and a driving screw shaft is installed at one end of the rotating motor, and the static electricity removal unit also includes a receiving table installed on the upper end surface of the static electricity treatment box, the upper end surface of the receiving table receives a second driving wheel connected vertically, and the PCB board for assembly is inserted into the inner cavity of the contact inner chamber from the side end surface of the static electricity treatment box, and the spiral shaft is driven to rotate by the rotating motor, and the upper end surface of the driving spiral shaft is used to drive the PCB board to move toward the inner wall of the contact inner chamber. This fit forms a damping effect, which absorbs the tiny vibrations generated by the robot during movement, and the fit provides a static electricity release path. When the PCB board contacts the inner cavity wall, the static electricity can be conducted out through the inner cavity wall, reducing the risk of static electricity damaging sensitive electronic components.

[0023] Compared with the prior art, the present invention has the following beneficial effects: 1. The design of the static removal unit can effectively remove static electricity from PCBs, reduce the risk of static damage to sensitive electronic components, and improve assembly reliability and product quality. The auxiliary unit provides stable support for the assembly mechanism, ensuring the stability of the assembly process. The first and second edge clamps in the assembly mechanism can flexibly clamp PCBs of different sizes to meet various assembly requirements.

[0024] 2. The reciprocating movement function of the moving part enables the robot to accurately adjust its position in the horizontal direction, ensuring that the electronic components can be accurately placed in the predetermined position. After completing the assembly of a component, the moving part can be quickly moved to the next assembly position, improving assembly efficiency and reducing non-production time. The moving function of the moving part can be combined with the rotation or telescopic function of the adjustment mechanism to achieve more complex assembly tasks and adapt to the installation requirements of components at different angles and depths. The driving rope can be replaced with rubber material or carbon fiber composite material as needed, providing the advantages of buffering and shock absorption and high strength and lightweight respectively. The length of the driving rope is adjustable. The short rope provides higher rigidity and stability, suitable for precise positioning; the long rope provides a larger range of motion and flexibility, adapting to complex assembly paths.

[0025] 3. During high-speed movement and frequent starts and stops, the inertia of the moving parts can assist in positioning, reduce the slight position deviation caused by the motor brake, and improve positioning accuracy. The sliding friction between the friction wheel in the adapter mechanism and the upper end surface of the PCB board has a shock-absorbing effect, reducing errors caused by vibration during assembly.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figures 1-8, Example 1, an electronic product automatic assembly robot, including an electrostatic removal unit 1, an auxiliary unit 2 and an assembly mechanism 3, the auxiliary unit 2 is installed on the upper end face of the electrostatic removal unit 1, and the assembly mechanism 3 is installed laterally on one side of the auxiliary unit 2, the assembly mechanism 3 includes a positioning cross frame 31 installed laterally on the side end face of the auxiliary unit 2, the side end face of the positioning cross frame 31 is laterally installed with a mounting frame 32, first edge clamps 33 are installed on both sides of the outer end wall of the mounting frame 32, second edge clamps 34 are installed on both sides of the outer end face of the first edge clamp 33, a moving member 35 is slidably installed at the bottom of the first edge clamp 33 and the second edge clamp 34, an adjustment mechanism 36 is fixedly installed on the top of the mounting frame 32, the mounting frame 32, the first edge clamp 33 and the second edge clamp 34 are all installed with a clamping push cross bar 37 on the side close to the positioning cross frame 31.

[0030] The movable member 35 is capable of reciprocating along the lower end surfaces of the first edge clamp 33 and the second edge clamp 34, clamping the end surfaces of the PCB to be processed between the first edge clamp 33 and the second edge clamp 34. The two sets of movable members 35 are connected to each other at the intervals between the first edge clamp 33 and the second edge clamp 34. The movable members 35 are mounted at the bottom of the first edge clamp 33 and the second edge clamp 34 and can reciprocate along their lower end surfaces. This movement function enables the robot to adjust its position horizontally so that electronic components can be accurately placed in predetermined locations. For example, a PCB can be placed horizontally between the second edge clamp 34. The reciprocating movement of the movable member 35 drives the reciprocating movement of the movable member 35, which can accurately place components such as resistors and capacitors in designated locations on the board. PCBs of different sizes may require components to be installed in different locations. The reciprocating movement function of the movable member 35 can adjust its range of motion to accommodate PCBs of different sizes, ensuring that all areas requiring assembly are covered.

[0031] The reciprocating movement function of the moving member 35 enables the robot to quickly move to the next assembly position after completing the assembly of one component and assemble the next component. This continuous operation improves assembly efficiency and reduces non-production time.

[0032] The movement function of the moving member 35 can be combined with the rotation or telescopic function of the component adjustment mechanism 36 to achieve more complex assembly tasks. For example, when installing a component that requires a specific angle or depth, the moving member 35 can be moved to the appropriate position.

[0033] When the component mover 35 needs to move to a target position at a relatively high speed and then stop quickly, its own inertia can assist in positioning. For example, during a high-speed placement process, the component mover 35 moves components to a specified position on a PCB at high speed. As it approaches the target position, the motor gradually slows down, allowing the component mover 35's inertia to continue moving a short distance until it stops at the precise location. This inertia-assisted positioning can reduce minor positional deviations caused by sudden motor braking and improve positioning accuracy.

[0034] In assembly tasks that require frequent starts and stops, the inertia of the moving element 35 can aid positioning. For example, when assembling multiple components on a circuit board, the moving element 35 needs to move and stop quickly between each component position. Leveraging inertia, the moving element 35 can more accurately stop at the target position each time, reducing jitter and positional deviation caused by the frequent starts and stops of the motor.

[0035] In embodiment 2, an adjustment mechanism 36 is installed horizontally at the top position of the first edge clamping member 33. The adjustment mechanism 36 includes a horizontal mounting member 361 and a first driving wheel 362 installed at the middle position of the bottom of the horizontal mounting member 361. The outer ring of the first driving wheel 362 is sleeved with a driving rope 363. The other end of the driving rope 363 is sleeved on the outer ring of the second driving wheel 364. The bottom of the second driving wheel 364 is installed vertically downward on the upper end surface of the static removal unit 1. The material and length of the driving rope 363 are replaced according to different needs, so that the adjustment mechanism 36 as a whole can be adjusted in length on the upper end surface of the mounting frame 32, the first edge clamping member 33 and the second edge clamping member 34. Under the overall drive of the adjustment mechanism 36, the side end surface of the horizontal mounting member 361 pushes the electronic components to be installed horizontally, thereby pushing the electronic components to the preset position.

[0036] The driving rope 363 can be replaced with a rubber material, which has excellent elasticity, can buffer and reduce shock, protect the robot and components from damage, and has good sealing performance to prevent dust and liquid from intruding. It is suitable for assembly environments with shock absorption and protection requirements.

[0037] The driving rope 363 can be replaced with a carbon fiber composite material, which is high in strength and lightweight, with excellent fatigue resistance and corrosion resistance. It can reduce weight while maintaining component strength and is suitable for the assembly of high-end electronic products.

[0038] The shorter drive rope 363 provides higher rigidity and stability, reduces bending and deformation during movement, ensures accuracy and reliability, and reduces motion inertia, making it suitable for assembly tasks requiring precise positioning and high rigidity.

[0039] The longer driving rope 363 provides a larger range of motion and flexibility, adapts to complex assembly paths and multi-position operations, increases the robot's workspace, and is suitable for tasks that require assembly operations in a larger space.

[0040] In embodiment 3, the assembly mechanism 3 further includes an adapter mechanism 38 installed at the bottom position of the mounting frame 32 and the clamping and pushing cross bar 37. The adapter mechanism 38 includes a vertical member 381 and a connecting member 382 installed transversely on the end faces of both sides of the vertical member 381. The lower end face of the connecting member 382 is transversely installed with a transverse assembly member 383. The edge of the transverse assembly member 383 is vertically provided with a swing member 384 on both sides. The front end face of the swing member 384 is provided with a connecting support tube 385. The bottom of the vertical member 381 and the swing member 384 are both transversely interspersed with friction wheels. 386, the bottom of the friction wheel 386 is attached to the top of the static removal unit 1, and the side end surface of the clamping and pushing cross bar 37 is attached to the top of the PCB board to be installed, so that the electronic components to be pushed can be moved to the correct position. During the movement, the adapter mechanism 38 is driven to move in the same direction as a whole. Because the horizontal assembly 383 and the swinging member 384 can swing back and forth with the connecting support tube 385 as the fulcrum, the friction wheels 386 at different positions are used to effectively push the electronic components on the PCB board.

[0041] When the clamping push bar 37 moves, the friction wheel 386 at the bottom of the vertical member 381 moves driven by it, and the friction wheel 386 at the bottom of the swinging member 384 is pulled laterally under the drive of the lateral driving force. At this time, the friction wheel 386 at the bottom of the swinging member 384 can perform static friction on the upper end surface of the PCB board. When the static friction force pushes the component, it produces a slight clamping effect, so that the component remains stable during the movement, avoiding damage to the component due to accidental collision or vibration, and improving the integrity of the component. The static friction force can automatically adjust the force according to the slight fluctuations and unevenness of the PCB board surface, thereby enhancing the robot's adaptability to different PCB board conditions, just like installing an "adaptive module" for the robot.

[0042] When the vertical member 381 moves back and forth with the side end surface of the clamping and pushing cross bar 37 as the fulcrum, the outer end wall of the friction wheel 386 contacts the upper end surface of the PCB board, and during the following movement of the friction wheel 386 at the bottom of the swinging member 384, the swinging member 384 is offset and swung at both ends of the horizontal assembly member 383 with the connecting support tube 385 as the fulcrum, so that the outer end surface of the friction wheel 386 slides and rubs against the upper end surface of the PCB board.

[0043] The sliding friction between friction wheel 386 and the upper surface of the PCB acts as a shock absorber, like an unexpected "shock pad" for the entire assembly system, reducing errors caused by vibration during assembly. The contact between friction wheel 386 and the upper surface of the PCB provides a stabilizing force. This stabilizing force prevents accidental sliding of the PCB, keeping the entire assembly platform stable under minor vibrations or collisions. It acts as an unexpected "stabilizer" for the entire system and can also propel the electronic components located inside friction wheel 386 to move laterally to their precise positions.

[0044] In embodiment 4, the auxiliary unit 2 includes a mounting bracket 21 and sleeves 22 mounted on both sides of the side end surface of the mounting bracket 21 . A protective cover 23 is sleeved on the outer ring of the mounting bracket 21 , and a telescopic pushing mechanism 24 is inserted into the inner cavity of the sleeve 22 .

[0045] The telescopic push mechanism 24 includes an insert 241 and a telescopic rod 242 mounted at one end of the insert 241. The insert 241 is movably connected to a push frame 243 via the telescopic rod 242. An arrangement member 244 is disposed transversely on the lower end surface of the push frame 243, and the insert 241 is laterally inserted into the inner cavity of the socket 22. Driven by an external motor, the arrangement member 244 telescopes with the telescopic rod 242 as a fulcrum. Driven by the push frame 243, the arrangement member 244 pushes the electronic components of the PCB board placed on the upper end surface of the receiving table 17. The arrangement member 244 is arranged transversely, which enables it to push the electronic components in the transverse direction, adapting to the horizontal layout of the components on the PCB board.

[0046] Example 5, the static electricity removal unit 1 includes a static electricity treatment box 11 and a contact inner chamber 12 opened in the inner cavity of the static electricity treatment box 11, a bottom opening hole 13 is opened on one side of the bottom position of the contact inner chamber 12, an edge bracket 14 is installed at the edge position of the static electricity treatment box 11, a rotating motor 15 is opened in the inner cavity of the edge bracket 14, and a driving screw shaft 16 is installed at one end of the rotating motor 15. The static electricity removal unit 1 also includes a receiving table 17 installed on the upper end surface of the static electricity treatment box 11, and the upper end surface of the receiving table 17 receives the second driving wheel 364 connected vertically, which will be used for The assembled PCB board is inserted into the inner cavity of the contact inner chamber 12 through the side end face of the electrostatic treatment box 11. The screw shaft 16 is driven to rotate by the rotary motor 15, and the upper end face of the screw shaft 16 is used to drive the PCB board toward the inner wall side of the contact inner chamber 12. This fit creates a damping effect, absorbing the tiny vibrations generated by the robot during movement. The fit also provides a static discharge path. When the PCB board contacts the inner cavity wall, the static electricity can be conducted away through the inner cavity wall, reducing the risk of static electricity damaging sensitive electronic components.

[0047] In summary: the end faces on both sides of the PCB board to be processed are clamped at the interval between the first edge clamp 33 or the second edge clamp 34, and the two groups of movable members 35 arranged laterally are connected to each other at the interval position through a transverse connector. The movable members 35 are installed at the bottom of the first edge clamp 33 and the second edge clamp 34 of the components and can move back and forth along their lower end faces. This movement function enables the robot to adjust its position in the horizontal direction so that electronic components can be accurately placed in predetermined positions. For example, the PCB board is placed laterally at the interval between the second edge clamp 34, and the transverse connector is driven by the transverse reciprocating movement of the movable members 35, so that components such as resistors and capacitors can be accurately placed in designated positions on the board.

[0048] PCB boards of different sizes may require components to be installed at different positions. The reciprocating movement function of the moving part 35 can adjust its movement range to adapt to PCB boards of different sizes, ensuring that all areas that require assembly can be covered.

[0049] The reciprocating movement function of the moving member 35 enables the robot to quickly move to the next assembly position after completing the assembly of one component and assemble the next component. This continuous operation improves assembly efficiency and reduces non-production time.

[0050] The movement function of the moving member 35 can be combined with the rotation or telescopic function of the component adjustment mechanism 36 to achieve more complex assembly tasks. For example, when installing a component that requires a specific angle or depth, the moving member 35 can be moved to the appropriate position.

[0051] When the component mover 35 needs to move to a target position at a relatively high speed and then stop quickly, its own inertia can assist in positioning. For example, during a high-speed placement process, the component mover 35 moves components to a specified position on a PCB at high speed. As it approaches the target position, the motor gradually slows down, allowing the component mover 35's inertia to continue moving a short distance until it stops at the precise location. This inertia-assisted positioning can reduce minor positional deviations caused by sudden motor braking and improve positioning accuracy.

[0052] In assembly tasks that require frequent starts and stops, the inertia of the moving element 35 can aid positioning. For example, when assembling multiple components on a circuit board, the moving element 35 needs to move and stop quickly between each component position. Leveraging inertia, the moving element 35 can more accurately stop at the target position each time, reducing jitter and positional deviation caused by the frequent starts and stops of the motor.

[0053] The material and length of the driving rope 363 are changed according to different needs, so that the length of the adjustment mechanism 36 as a whole can be adjusted on the upper end surface of the installation frame 32, the first edge clamp 33 and the second edge clamp 34. Under the overall drive of the adjustment mechanism 36, the side end surface of the horizontal mounting member 361 pushes the electronic components to be installed horizontally, thereby pushing the electronic components to the preset position.

[0054] The driving rope 363 can be replaced with a rubber material, which has excellent elasticity, can buffer and reduce shock, protect the robot and components from damage, and has good sealing performance to prevent dust and liquid from intruding. It is suitable for assembly environments with shock absorption and protection requirements.

[0055] The driving rope 363 can be replaced with a carbon fiber composite material, which is high in strength and lightweight, with excellent fatigue resistance and corrosion resistance. It can reduce weight while maintaining component strength and is suitable for the assembly of high-end electronic products.

[0056] The shorter drive rope 363 provides higher rigidity and stability, reduces bending and deformation during movement, ensures accuracy and reliability, and reduces motion inertia, making it suitable for assembly tasks requiring precise positioning and high rigidity.

[0057] The longer driving rope 363 provides a larger range of motion and flexibility, adapts to complex assembly paths and multi-position operations, increases the robot's workspace, and is suitable for tasks that require assembly operations in a larger space.

[0058] The side end surface of the clamping and pushing cross bar 37 is in contact with the top of the PCB board to be installed, so that the electronic component to be pushed can be moved to the correct position. During the movement, the adapter mechanism 38 is driven to move in the same direction as a whole. Because the horizontal assembly part 383 and the swing part 384 can swing back and forth with the connecting support tube 385 as the fulcrum, the friction wheels 386 at different positions are used to effectively push the electronic components of the PCB board into position.

[0059] When the clamping push bar 37 moves, the friction wheel 386 at the bottom of the vertical member 381 moves driven by it, and the friction wheel 386 at the bottom of the swinging member 384 is pulled laterally under the drive of the lateral driving force. At this time, the friction wheel 386 at the bottom of the swinging member 384 can perform static friction on the upper end surface of the PCB board. When the static friction force pushes the component, it produces a slight clamping effect, so that the component remains stable during the movement, avoiding damage to the component due to accidental collision or vibration, and improving the integrity of the component. The static friction force can automatically adjust the force according to the slight fluctuations and unevenness of the PCB board surface, thereby enhancing the robot's adaptability to different PCB board conditions, just like installing an "adaptive module" for the robot.

[0060] When the vertical member 381 moves back and forth with the side end surface of the clamping and pushing cross bar 37 as the fulcrum, the outer end wall of the friction wheel 386 contacts the upper end surface of the PCB board, and during the following movement of the friction wheel 386 at the bottom of the swinging member 384, the swinging member 384 is offset and swung at both ends of the horizontal assembly member 383 with the connecting support tube 385 as the fulcrum, so that the outer end surface of the friction wheel 386 slides and rubs against the upper end surface of the PCB board.

[0061] The sliding friction between friction wheel 386 and the upper surface of the PCB acts as a shock absorber, like an unexpected "shock pad" for the entire assembly system, reducing errors caused by vibration during assembly. The contact between friction wheel 386 and the upper surface of the PCB provides a stabilizing force. This stabilizing force prevents accidental sliding of the PCB, keeping the entire assembly platform stable under minor vibrations or collisions. It acts as an unexpected "stabilizer" for the entire system and can also propel the electronic components located inside friction wheel 386 to move laterally to their precise positions.

[0062] Driven by an external motor, the arranging member 244 is telescopically adjusted with the telescopic rod 242 as a fulcrum, so that the arranging member 244 pushes the electronic components of the PCB board placed on the upper end surface of the receiving table 17 under the drive of the pushing frame 243. The arranging member 244 is a pushing member arranged in a horizontal direction. This arrangement method enables the arranging member 244 to push the electronic components in the horizontal direction to adapt to the horizontal layout of the components on the PCB board.

[0063] The PCB to be assembled is inserted from the side of the electrostatic treatment box 11 into the inner cavity of the contact inner chamber 12. The rotary motor 15 drives the screw shaft 16 to rotate, and the upper end of the screw shaft 16 drives the PCB toward the inner wall of the contact inner chamber 12. This contact creates a damping effect, absorbing the tiny vibrations generated by the robot during movement. The contact also provides a path for electrostatic discharge. When the PCB contacts the inner cavity wall, static electricity can be conducted away through the inner cavity wall, reducing the risk of static electricity damaging sensitive electronic components.
