Description

Technical Field

[0001] This invention relates to the field of automatic assembly technology, specifically to an adjustable-spacing conveying mechanism and automatic assembly equipment. Background Technology

[0002] In existing automated assembly equipment, the assembly and transportation of parts typically involves placing the parts on a base, which is then placed on a conveyor belt for transport. However, during transport, the base is susceptible to external environmental interference, such as vibration and airflow, causing it to shift and deviate from its intended assembly position, resulting in assembly errors. The usual solution is to stop the equipment and manually correct the issue, resuming operation only after the parts have been repositioned. This requires manual intervention, increasing operating costs and time. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an adjustable spacing conveying mechanism and an automatic assembly equipment to solve the problem mentioned in the background art of the lack of a fixing device for the base.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an adjustable-spacing conveyor mechanism, comprising a conveyor belt, a base, a drive wheel for driving the conveyor belt to rotate, a limiting block and a locking component mounted on the conveyor belt; The base is used to support the accessories to be assembled. The conveyor belt is a closed ring structure, with its outer ring being the contact surface and its inner ring being the transmission surface; The transmission surface is provided with a number of continuous and spaced grooves to cooperate with the drive wheel to drive its rotation; The limiting block is installed on the contact surface, and both ends of the limiting block extend to the transmission surface, and limiting holes are provided for the locking member to pass through; The position of the limiting hole corresponds to one of the grooves, so that the locking member can pass through the limiting hole and be at least partially embedded in the groove, and form a cooperation with the groove to restrict the movement of the limiting block; When it is necessary to transport the base, adjust the spacing between adjacent limit blocks to match the size of the base, so as to limit the base from shifting during the transport process.

[0005] In a further optimization of the present invention, a locking ring is provided at one end of the locking member and a slot is provided at the other end; The locking ring is larger than the limiting hole, which is used to prevent the locking component from completely passing through the limiting hole; A retaining spring is installed on the slot; When the locking element with the slotted end passes through the limiting holes at both ends of the limiting block until the locking ring abuts against the limiting hole, it restricts the locking element from moving further. Then, a retaining spring is installed on the slot to prevent the locking element from disengaging from the limiting block.

[0006] A further optimization of the present invention is that the limiting block is provided with a rotatably connected rolling shaft; The rolling shaft works in conjunction with the conveyor belt to reduce the frictional resistance of the limiting block during movement.

[0007] In a further optimization of the present invention, the drive wheel is provided with a plurality of spaced clearance portions in the circumferential direction; The travel distance between adjacent clearance parts is adapted to the travel distance between two adjacent locking parts; The avoidance part is used to avoid the protruding structure formed after the limit block and locking member are installed.

[0008] A further optimization of the present invention includes a transmission channel, a first lifting mechanism, and a second lifting mechanism; The first lifting mechanism and the second lifting mechanism are installed on both sides of the transmission channel; When the conveyor belt transports the base to the location of the second lifting mechanism, the second lifting mechanism carries the base and places it in the transmission channel. When the transmission channel moves the base to the position of the first lifting mechanism, the first lifting mechanism carries the base and places it on the conveyor belt.

[0009] A further optimization of the present invention includes a first pushing device and a second pushing device installed on both sides of the transmission channel; When the base enters the second lifting mechanism via the conveyor belt, and is moved down by the second lifting mechanism to a position corresponding to the transmission channel, the second pushing device pushes the base into the transmission channel. When the base enters the first lifting mechanism through the transmission channel and is moved upward by the first lifting mechanism to a position corresponding to the conveyor belt, the first pushing device pushes the base into the conveyor belt.

[0010] An automated assembly device includes a conveying mechanism and an assembly mechanism that cooperates with the conveying mechanism to perform assembly actions on the parts to be assembled. The conveying mechanism is an adjustable-spacing conveying mechanism as described above; The assembly mechanism includes a moving device, a first driving device, an actuating device, and a coupling for connecting the first driving device and the actuating device. The first driving device is connected to one end of the coupling and is used to drive the coupling to rotate. The actuating device is provided with a connecting rod at the position corresponding to the coupling. The connecting rod is axially movable to the coupling and circumferentially fixed. The moving device is rotatably connected to the connecting rod and is axially fixed, used to drive the actuating device to move; The length of the connecting rod is greater than the moving distance of the moving device to prevent the connecting rod from disengaging from the coupling.

[0011] In a further optimization of the present invention, the assembly mechanism includes a sliding seat; The first driving device is fixedly connected to the sliding seat; The moving device is movably connected to the sliding seat; The actuating device includes a first rotating member, a second rotating member, a first gripping member, and a second gripping member; The connecting rod is provided with a rotation point; Both the first rotating component and the second rotating component are rotatably connected to the rotation point; The first gripper is rotatably connected to the first rotating member, and the second rotating member is rotatably connected to the second gripper. The sliding seat is provided with a through hole for the connecting rod to pass through; The connecting rod portion passes through the through hole; When the connecting rod moves and comes into contact with the sliding seat, the first rotating member and the second rotating member rotate around the rotation point, and drive the first clamping member and the second clamping member to complete the clamping action. When the connecting rod moves and separates from the sliding seat, the first rotating member and the second rotating member rotate around the rotation point, and drive the first clamping member and the second clamping member to release the clamping action.

[0012] A further optimization of the present invention is that the sliding seat is provided with a slide rail; Both the first and second clamping components are provided with protrusions installed inside the slide rail; When the first rotating member and the second rotating member rotate, the slide rail restricts the protrusion, thereby driving the first clamping member and the second clamping member to move along the fixed trajectory of the slide rail.

[0013] In a further optimization of the present invention, the assembly mechanism further includes a second drive device and a base; The sliding seat is slidably connected to the base; The second driving device is connected to the sliding seat and is used to drive the sliding seat to move along the trajectory set by the base.

[0014] The beneficial effects of this invention are as follows: (1) The base is fixed by installing limit blocks and locking parts on the conveyor belt.

[0015] (2) By using detachable limit blocks and locking parts, the spacing between adjacent limit blocks can be adjusted to match the size of the base and form an effective clamping. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0026] Reference Figure 1-8 As shown, an adjustable-spacing conveyor mechanism 20 includes a conveyor belt 10, a base 11, a drive wheel 12 for driving the conveyor belt 10 to rotate, a limiting block 13 mounted on the conveyor belt 10, and a locking member 14. Base 11 is used to support the accessories to be assembled; The conveyor belt 10 is a closed ring structure, with its outer ring being the contact surface 101 and its inner ring being the transmission surface 102. The transmission surface 102 is provided with a number of continuous and spaced grooves 1021 to cooperate with the drive wheel 12 to drive it to rotate; The limiting block 13 is installed on the contact surface 101, and both ends of the limiting block 13 extend to the transmission surface 102, and a limiting hole 131 is provided for the locking member 14 to pass through. The position of the limiting hole 131 corresponds to one of the grooves 1021, so that the locking member 14 can pass through the limiting hole 131 and be at least partially embedded in the groove 1021, and form a cooperation with the groove 1021 to restrict the movement of the limiting block 13; When it is necessary to transport the base 11, adjust the spacing between adjacent limit blocks 13 to match the size of the base 11, so as to limit the base 11 from shifting during the transport process.

[0027] like Figure 1 As shown, during operation, the drive wheel 12 rotates and its teeth mesh with the groove 1021 on the inner ring transmission surface 102 of the conveyor belt 10, driving the conveyor belt 10 to make a circular motion. The limiting block 13 is fixedly installed on the outer ring contact surface 101 of the conveyor belt 10 through the locking member 14 and moves together with the conveyor belt 10. When a base 11 of a specific size needs to be transported, the operator first removes the locking piece 14 from the limiting hole 131, and then moves the limiting block 13 to the target position along the transmission surface 102 of the conveyor belt 10. At this time, the limiting hole 131 corresponds to the groove 1021. The locking piece 14 is passed through one side limiting hole 131 and then through the groove 1021, and finally through the other side limiting hole 131. The cooperation between the locking piece 14 and the groove 1021 restricts the movement of the limiting block 13 along the conveyor belt 10, thereby fixing the limiting block 13 in this position. Compared with the prior art, the base 11 is usually installed on the conveyor belt 10, and then the parts to be assembled are installed on the base 11, so that the conveyor belt 10 drives the parts to move to the set assembly position through the base 11. However, the base 11 lacks a fixing device during the installation process. Some improved solutions use matching parts to fix the base 11 at a fixed position on the conveyor belt 10, but this may damage the conveyor belt 10. Also, when the size of the base 11 changes, the fixing parts cannot be well adapted to the size of the base 11. This application adjusts the spacing between two adjacent limiting blocks 13 to match the width or length of the base 11. When the base 11 is placed between two adjacent limiting blocks 13, the limiting blocks 13 provide lateral limiting for the base 11, effectively preventing the base 11 from shifting or deviating due to external interference such as vibration and airflow during the conveying process. This ensures that the parts to be assembled can be accurately delivered to the preset assembly position, avoiding assembly errors caused by the offset of the base 11. No manual intervention is required to correct the errors, reducing operating costs and working time. At the same time, the closed ring structure of the conveyor belt 10 ensures the continuity and stability of the conveying process. Regarding the problem that the protrusion 21332 formed by the limiting block 13 and the locking member 14 may interfere with the teeth of the drive wheel 12, a drive wheel 12 with a larger tooth depth can be used to cooperate with the conveyor belt 10. In this way, the protrusion 21332 will be embedded in the teeth. Although it is not fully engaged, it can still achieve the function required by the present invention. At the same time, different spacing requirements can be achieved by replacing the drive wheel 12. This does not affect the use of the above structure and the solution of the technical problem to be solved by the present invention.

[0028] Preferably, the locking member 14 has a locking ring 141 at one end and a slot 142 at the other end; The size of the locking ring 141 is larger than the size of the limiting hole 131, which is used to prevent the locking member 14 from completely passing through the limiting hole 131; A retaining ring 143 is installed on the retaining slot 142; When the locking member 14 with the slot 142 at one end passes through the limiting holes 131 at both ends of the limiting block 13 until the locking ring 141 abuts against the limiting hole 131, the locking member 14 is restricted from moving further. Then, the snap ring 143 is installed on the slot 142 to restrict the locking member 14 from disengaging from the limiting block 13.

[0029] like Figure 2 and Figure 3 As shown, when it is necessary to fix the limiting block 13, the end of the locking member 14 with the slot 142 is inserted into the limiting hole 131 from one side of the limiting block 13, and moves along the limiting hole 131 towards the groove 1021. When the locking member 14 moves to the point where the locking ring 141 abuts against the edge of the limiting hole 131, because the size of the locking ring 141 is larger than the diameter of the limiting hole 131, it can prevent the locking member 14 from continuing to pass through the limiting block 13. At this time, the other end of the locking member 14 has been embedded in the groove 1021 and forms a cooperation with the groove 1021. The snap ring 143 is then inserted into the slot 142. The elasticity of the snap ring 143 causes it to fit tightly against the inner wall of the slot 142, forming an axial lock and preventing the locking member 14 from exiting the limiting hole 131. When unlocking is required, first remove the retaining ring 143, and then pull the locking piece 14 out of the limiting hole 131. This structure enables quick installation and removal of the locking element 14 without the need for additional tools, making operation simple and improving the efficiency of adjusting the spacing of the limit blocks 13. At the same time, the locking of the snap ring 143 ensures that the locking element 14 will not loosen due to vibration during equipment operation, thus guaranteeing the reliability of the fixation of the limit blocks 13.

[0030] Preferably, the limiting block 13 is provided with a rotatably connected rolling shaft 132; The rolling shaft 132 cooperates with the conveyor belt 10 to reduce the frictional resistance of the limiting block 13 during movement.

[0031] like Figure 4 As shown, the conveyor belt 10 carries the parts to be assembled through the support base 11. After the assembly action, the parts to be assembled are removed after the assembly is completed, and the base 11 continues to move with the conveyor belt 10 and re-enters the cycle. The conveyor belt 10 carries the base 11. When the weight it forms is large, the conveyor belt 10 needs to cooperate with the support assembly or other components to transport the base 11. If there are no other components, the conveyor belt 10 will sag due to its weight, thus failing to mesh with the drive wheel 12. When transported in conjunction with other components, the limiting block 13 will experience sliding friction with the support assembly, resulting in a higher output power required for the drive wheel 12; To solve the above problems, this embodiment, for example... Figure 2 and Figure 3 As shown, a rolling shaft 132 is provided on the limiting block 13; When the conveyor belt 10 drives the limiting block 13 to rotate, the rolling shaft 132 abuts against the support component (which may also be the transmission channel 15 mentioned below), and the rolling shaft 132 transforms the original sliding friction between the limiting block 13 and the support component into rolling friction. The coefficient of friction of rolling friction is much smaller than that of sliding friction, thus significantly reducing the force required when the conveyor belt 10 moves the limit block 13, reducing the wear on the surface of the limit block 13 and the support components, extending the service life, and reducing the output power requirement of the drive wheel 12.

[0032] Preferably, the drive wheel 12 is provided with a plurality of spaced clearance portions 121 in the circumferential direction; The travel between adjacent clearance parts 121 is adapted to the travel between two adjacent locking parts 14; The avoidance part 121 is used to avoid the protruding structure formed after the limit block 13 and the locking member 14 are installed.

[0033] like Figure 1As shown, when the drive wheel 12 rotates and drives the conveyor belt 10 to move, after the limit block 13 and the locking member 14 are installed, a protruding structure of a certain height will be formed at the position of the inner ring transmission surface 102 of the conveyor belt 10, protruding from the inner surface of the conveyor belt 10. When the drive wheel 12 engages with the groove 1021 on the transmission surface 102, the protruding structure formed by the limiting block 13 and the locking member 14 may interfere with and collide with the drive wheel 12, affecting the normal operation of the conveyor belt 10. Therefore, in this embodiment, the drive wheel 12 is provided with a clearance part 121; like Figure 1 As shown, the avoidance part 121 provided on the drive wheel 12 is a recessed structure. The spacing between adjacent avoidance parts 121 is adapted to the spacing between two adjacent locking members 14. When the protruding structure moves to the position of contacting the drive wheel 12, the avoidance part 121 is aligned with the protruding structure and provides a accommodating space, avoiding interference and collision, ensuring that the drive wheel 12 can smoothly drive the conveyor belt 10 to rotate, and at the same time ensuring that the limit block 13 and the locking member 14 will not be damaged by the collision of the drive wheel 12 during the transmission process.

[0034] Preferably, it also includes a transmission channel 15, a first lifting mechanism 16, and a second lifting mechanism 161; The first lifting mechanism 16 and the second lifting mechanism 161 are installed on both sides of the transmission channel 15; When the conveyor belt 10 transports the base 11 to the location of the second lifting mechanism 161, the second lifting mechanism 161 carries the base 11 and places it in the transmission channel 15. When the transmission channel 15 moves the base 11 to the position of the first lifting mechanism 16, the first lifting mechanism 16 carries the base 11 and places it on the conveyor belt 10.

[0035] When the conveyor belt 10 is long, too many bases 11 or parts to be installed will result in excessive weight, causing the conveyor belt 10 to sag in some areas and affecting the meshing with the drive wheel 12; while reducing the length of the conveyor belt 10 will reduce the number of parts to be installed in one conveying, thus reducing work efficiency. To solve the above problems, this embodiment reduces the number of bases 11 that the conveyor belt 10 needs to carry during cyclic transportation by realizing the transfer of bases 11 between different levels; like Figure 4 As shown, during operation, the conveyor belt 10 transports the parts to be assembled, which are carried on the base 11, from one end. When it reaches the position of the second lifting mechanism 161, a person or a robotic arm will pick up and remove the assembled parts from the base 11. The lifting platform of the second lifting mechanism 161 rises to be flush with the upper surface of the conveyor belt 10 or directly clamps the base 11, and then descends and places the base 11 at the entrance of the transmission channel 15. If there is a large gap between the base 11 and the transmission channel 15, the base 11 can be driven into the transmission channel 15 by adding rollers or other means. The transmission channel 15 is equipped with a conveying power device, which can drive the base 11 to move along the channel to the position of the first lifting mechanism 16. After the base 11 arrives, the lifting platform of the first lifting mechanism 16 descends to pick up the base 11, and then rises to a position flush with the upper surface of the conveyor belt 10, and places the base 11 back on the conveyor belt 10. A person or a robotic arm places the new part to be assembled on the base 11, and then the conveyor belt 10 continues to transport it. This structure realizes a closed-loop conveying path, which can make full use of space and transfer the assembled base 11 from the conveyor belt 10 to the transmission channel 15, reducing the number of bases 11 on the conveyor belt 10, thereby reducing the weight carried by the conveyor belt 10 and preventing the conveyor belt 10 from sagging due to excessive load. Meanwhile, after the base 11 is transported to the first lifting mechanism 16 through the transmission channel 15, the first lifting mechanism 16 transports the base 11 back to the assembly start end, and the cycle is repeated to realize a fully automatic conveying cycle, reduce manual operation steps, and improve production efficiency.

[0036] Preferably, it also includes a first pushing device 17 and a second pushing device 171 installed on both sides of the transmission channel 15; When the base 11 enters the second lifting mechanism 161 via the conveyor belt 10, and is moved down by the second lifting mechanism 161 to the position corresponding to the transmission channel 15, the second pushing device 171 pushes the base 11 into the transmission channel 15. When the base 11 enters the first lifting mechanism 16 through the transmission channel 15, and is moved upward by the first lifting mechanism 16 to the position corresponding to the conveyor belt 10, the first pushing device 17 pushes the base 11 into the conveyor belt 10.

[0037] like Figure 4 As shown, when the base 11 needs to enter the second lifting mechanism 161 from the conveyor belt 10, the base 11 moves with the conveyor belt 10 to the receiving position of the second lifting mechanism 161. The second lifting mechanism 161 rises to pick up the base 11 and then descends. When the base 11 descends to a position flush with the entrance of the transmission channel 15, the second pushing device 171 installed at the entrance of the transmission channel 15 is activated to push the base 11 into the transmission channel 15, so that the base 11 completely enters the transmission channel 15. Similarly, when the base 11 moves to the position of the first lifting mechanism 16 through the transmission channel 15, the first lifting mechanism 16 descends to pick up the base 11 and rises to be flush with the conveyor belt 10. The first pushing device 17 installed at the entrance of the conveyor belt 10 is activated to push the base 11 from the first lifting mechanism 16 onto the conveyor belt 10. After the conveyor belt 10 transports the base 11 to the assembly site, it will continue to move in the circular direction, so that the base 11 will naturally move towards the position of the first lifting mechanism 16 or the second lifting mechanism 161. Therefore, there is no need to set up an additional pushing device to move the base 11 on the conveyor belt 10 towards the lifting mechanism. The pushing device has a high success rate in pushing the base 11 into the conveyor belt 10 or the transmission channel 15. It can replace manual pushing or additional conveying mechanism 20, and realize the automatic transfer of the base 11 between the lifting mechanism and the transmission channel 15, and between the lifting mechanism and the conveyor belt 10. This further reduces manual intervention and improves the degree of automation. At the same time, the thrust of the pushing device is adjustable, which can adapt to bases 11 of different weights and sizes. The transfer process is stable and reliable.

[0038] An automatic assembly device includes a conveying mechanism 20 and an assembly mechanism 21 that cooperates with the conveying mechanism 20 to perform assembly operations on the parts to be assembled. The conveying mechanism 20 adopts the adjustable spacing conveying mechanism 20 as described above; Assembly mechanism 21 includes a moving device 211, a first driving device 212, an actuating device 213, and a coupling 214 for connecting the first driving device 212 and the actuating device 213; The first driving device 212 is connected to one end of the coupling 214 and is used to drive the coupling 214 to rotate. The actuating device 213 is provided with a connecting rod 2131 at the position corresponding to the coupling 214. The connecting rod 2131 is axially movable to the coupling 214 and circumferentially fixed. The moving device 211 is rotatably connected to the connecting rod 2131 and is axially fixed, and is used to drive the actuating device 213 to move. The length of the connecting rod 2131 is greater than the moving distance of the moving device 211 to prevent the connecting rod 2131 from disengaging from the coupling 214.

[0039] like Figure 8 As shown, in the automatic assembly equipment of this embodiment, the conveying mechanism 20 is responsible for conveying the parts to be assembled and the base 11 to the assembly station. The conveying mechanism 20 has any of the above structures, which can effectively prevent the base 11 from shifting during the conveying process and ensure that the parts to be assembled are accurately delivered to the assembly position. like Figure 6 As shown, during operation, the first drive device 212 starts and drives the coupling 214 to rotate. Since the connecting rod 2131 and the coupling 214 are circumferentially fixed, the rotation of the coupling 214 drives the connecting rod 2131 to rotate around the axis. Meanwhile, the moving device 211 is rotatably connected to the connecting rod 2131 and is axially fixed. The movement of the moving device 211 will drive the connecting rod 2131 to move axially. However, since the connecting rod 2131 and the coupling 214 are axially movable, the rotation of the coupling 214 will not be interfered with by the axial movement of the connecting rod 2131. The length of the connecting rod 2131 is set to be greater than the moving distance of the moving device 211, so as to ensure that when the moving device 211 completes the maximum stroke, the connecting rod 2131 always remains connected to the coupling 214 and will not disengage from the coupling 214, thus ensuring the continuity and reliability of the movement of the actuating device 213. This structure enables the actuating device 213 to perform rotational and linear motion, giving it the functions of movement and rotation. This allows the actuating device 213 to clamp bolts, place them on the parts to be installed, and rotate to complete the tightening action.

[0040] Preferably, the assembly mechanism 21 includes a sliding seat 215; The first driving device 212 is fixedly connected to the sliding seat 215; The moving device 211 is movably connected to the sliding seat 215; The actuation device 213 includes a first rotating member 2132, a second rotating member 21321, a first gripping member 2133, and a second gripping member 21331; A rotation point 21311 is provided on the connecting rod 2131; Both the first rotating component 2132 and the second rotating component 21321 are rotatably connected to the rotating point 21311; The first clamping member 2133 is rotatably connected to the first rotating member 2132, and the second rotating member 21321 is rotatably connected to the second clamping member 21331. The sliding seat 215 is provided with a through hole 2151 for the connecting rod 2131 to pass through; Connecting rod 2131 passes through through hole 2151; When the connecting rod 2131 moves and comes into contact with the sliding seat 215, the first rotating member 2132 and the second rotating member 21321 rotate around the rotation point 21311, and drive the first clamping member 2133 and the second clamping member 21331 to complete the clamping action. When the connecting rod 2131 moves and separates from the sliding seat 215, the first rotating member 2132 and the second rotating member 21321 rotate around the rotation point 21311, and drive the first clamping member 2133 and the second clamping member 21331 to release the clamping action.

[0041] like Figure 6 and Figure 7As shown, the sliding seat 215 is fixedly connected to the first driving device 212 and serves as the support and motion base for the entire moving device 211, the first driving device 212, and the action device 213. The movable device 211 is movably connected to the sliding base 215 and can slide on the sliding base 215 in a preset direction. When the connecting rod 2131 moves toward the sliding seat 215 under the drive of the moving device 211 and comes into contact with the inner wall of the sliding seat 215, the rotation point 21311 on the connecting rod 2131 is subjected to axial thrust. Since the first rotating member 2132 and the second rotating member 21321 are both rotatably connected to the rotation point 21311, the axial movement of the rotation point 21311 will push the first rotating member 2132 and the second rotating member 21321 to rotate around the rotation point 21311. When the first rotating component 2132 rotates, it drives the first clamping component 2133 connected to it to move. When the second rotating component 21321 rotates, it drives the second clamping component 21331 connected to it to move. The two clamping components move closer to each other and complete the clamping action on the workpiece. When the connecting rod 2131 moves in the opposite direction and separates from the sliding seat 215, under the action of gravity, the first rotating member 2132 and the second rotating member 21321 rotate in opposite directions, causing the first clamping member 2133 and the second clamping member 21331 to open and release the clamping of the workpiece. This structure can achieve the clamping and opening of the gripper through the simple linear motion of the connecting rod 2131. The mechanical structure is simple and reliable, with a fast response speed, and is suitable for the rapid clamping and placement of small parts.

[0042] Preferably, a slide rail 2152 is provided on the sliding seat 215; Both the first clamping component 2133 and the second clamping component 21331 are provided with a protrusion 21332 installed in the slide rail 2152; When the first rotating member 2132 and the second rotating member 21321 rotate, the protrusion 21332 is restricted by the slide rail 2152, thereby driving the first clamping member 2133 and the second clamping member 21331 to move along the fixed trajectory of the slide rail 2152.

[0043] like Figure 6 As shown, the slide rail 2152 is fixedly installed on the sliding seat 215, and the protrusions 21332 on the first clamping member 2133 and the second clamping member 21331 are embedded in the slide rail 2152 and can slide along the slide rail 2152. When the first rotating member 2132 and the second rotating member 21321 rotate around the rotation point 21311, the clamping member is driven to move through the connecting rod 2131. The protrusion 21332 on the clamping member slides in the slide rail 2152. The guiding effect of the slide rail 2152 on the protrusion 21332 restricts the movement trajectory of the clamping member, so that the first clamping member 2133 and the second clamping member 21331 can only move along the preset trajectory of the slide rail 2152, thus avoiding the clamping member from deviating or getting stuck during the movement. This structure ensures the precision and stability of the clamping movement, enabling the clamping parts to be accurately aligned with the workpiece to be clamped, thus improving assembly accuracy. At the same time, the horizontal clamping provides greater stability compared to the inclined clamping bolts.

[0044] Preferably, the assembly mechanism 21 further includes a second drive device 216 and a base 217; The sliding seat 215 is slidably connected to the base 217; The second drive device 216 is connected to the sliding seat 215 and is used to drive the sliding seat 215 to move along the trajectory set by the base 217.

[0045] like Figure 7 As shown, the base 217 serves as the mounting foundation for the entire assembly mechanism 21 and is fixed to the equipment body. The sliding seat 215 is slidably connected to the base 217 and can move along a preset trajectory on the base 217; The second drive device 216 is fixedly connected to the sliding seat 215 and can be a cylinder, hydraulic cylinder or motor drive device, etc. When the second drive device 216 is started, its output end pushes or pulls the sliding seat 215 to move along the guide rail track on the base 217. Since the entire actuation device 213, connecting rod 2131, moving device 211, etc. are all installed on the sliding seat 215, the movement of the sliding seat 215 will cause the working position of the assembly mechanism 21 to change, so as to avoid the first clamping part 2133 and the second clamping part 21331 becoming loose when the connecting rod 2131 moves, thus preventing the assembly action from being unable to be completed. The base 217 is equipped with such Figure 7 As shown, it is set in both horizontal and vertical directions to meet the actual assembly process requirements; Meanwhile, in this embodiment, multiple assembly mechanisms 21 can be added to complete the assembly of multiple parts to be assembled simultaneously, thereby improving production efficiency. Multiple workstations can also be set up; when an assembly requires assembly at multiple locations, it passes through multiple assembly mechanisms 21 sequentially to complete all its assembly processes. The process can be divided into two actions: pre-tightening and locking. The pre-tightening action initially positions the parts to be assembled and applies a small pre-tightening force, while the locking action completely fixes the parts to prevent damage caused by excessive force in a single action.

[0046] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
