Abstract

This invention relates to the field of welded structural component processing technology. The invention discloses a surface treatment device for welded structural components in a battery swapping station, comprising a machine body, a robotic arm rotatably mounted on the top of the outer wall of the machine body, a grinding machine fixedly mounted on the top of the outer wall of the machine body, and a robotic claw rotatably mounted on the top of the outer wall of the robotic arm. When the exposed surface of the workpiece is finished being ground, the robotic claw moves the workpiece to the surface of the machine body, causing a moving plate to move due to the resistance of the machine body, and generating a pushing force on a force-bearing block, causing the force-bearing block to move.

Description

Technical Field

[0001] This invention relates to the field of welded structural component processing technology, and specifically to a surface treatment device for welded structural components in a battery swapping station. Background Technology

[0002] The battery swapping station welded structural component processing device is a special surface grinding and processing equipment for the welded structural components of the battery swapping station. It automatically completes the grinding and repair of plastic parts flash, burrs, surface scratches and injection molding defects. The grinding force is controllable and does not damage the substrate. The processing is uniform and stable, suitable for batch processing, effectively improving the flatness of the parts and providing a qualified base surface for subsequent spraying and bonding processes. When the robotic arm drives the workpiece for grinding, the contact surface between the robotic claw and the workpiece becomes a grinding blind spot due to the tight fit between them. If the clamping contact surface of the welded structural component of the battery swapping station is an assembly mating surface, the remaining ungrinded allowance will directly cause the part to be unable to be accurately inserted into the corresponding installation position, resulting in assembly jamming and excessive fit gaps. When the existing equipment changes the clamping point, a certain offset will occur during the movement of the workpiece, which will affect the grinding accuracy. To address the above problems, the following solutions are proposed. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a surface treatment device for welded structural components of a battery swapping station, comprising a body, a robotic arm rotatably mounted on the top of the outer wall of the body, a grinding machine fixedly mounted on the top of the outer wall of the body, and a robotic claw rotatably mounted on the top of the outer wall of the robotic arm, and further comprising: A braking mechanism is slidably mounted on the bottom of the outer wall of the mechanical gripper. The braking mechanism includes a movable plate that is slidably connected to the bottom of the outer wall of the mechanical claw, and a force-bearing block is slidably connected to the bottom of the outer wall of the mechanical claw. The protective mechanism is slidably mounted on the outer wall of the braking mechanism. The protection mechanism includes a triangular block that is slidably connected to the bottom of the outer wall of the force-bearing block, and a rotating rod that is rotatably connected to the bottom of the outer wall of the mechanical claw. The cleaning mechanism is fixedly installed on the outer wall of the protective structure.

[0004] Preferably, the braking mechanism includes: The force-bearing component is slidably mounted on the bottom of the outer wall of the robotic gripper. The fixing component is fixedly installed on the side wall of the load-bearing component; When the fuselage comes into contact with the force-bearing component, and as the mechanical claw continues to move, the fuselage generates a thrust on the force-bearing component.

[0005] Preferably, the protection mechanism includes: The contact component is slidably disposed on the outer wall of the force-bearing component; A movable component is slidably disposed on the outer wall of the force-bearing component; When the contact component moves, the moving component moves synchronously with the force-bearing component.

[0006] Preferably, the cleaning facility includes: The scraping component is fixedly installed on the outer wall of the movable component; When the scraping component comes into contact with the mechanical gripper, it is resisted by the mechanical gripper and moves again.

[0007] Preferably, the force-bearing component includes a shaped block that is slidably connected to the inner wall of the force-bearing block; When the exposed area of ​​the workpiece surface is finished, the mechanical claw moves the workpiece to the surface of the machine body, causing the moving plate to move due to the resistance of the machine body. When the moving plate moves, it generates a pushing force on the force block, causing the force block to move, and the irregular block moves along with it.

[0008] Preferably, the fixing component includes a spring fixedly connected to the side wall of the force-bearing block, a spring sheet fixedly connected to the inner wall of the force-bearing block, and a rotating plate rotatably connected to the bottom of the outer wall of the mechanical claw. When the irregular block comes into contact with the workpiece, as the force-bearing block continues to move, the irregular block moves relative to the force-bearing block. When the force-bearing block is about to stop moving, the force-bearing block generates a pushing force on the rotating plate, causing the rotating plate to rotate and exert pressure on its own torsion spring. When the rotating plate is about to stop rotating, it achieves the restriction of the irregular block.

[0009] Preferably, the contact assembly includes a force-applying plate slidably connected to the inner wall of the irregular block, a spring piece fixedly connected to the top of the outer wall of the force-applying plate, a plurality of force-relieving plates rotatably connected to the outer wall of the irregular block, and a torsion spring sleeved on the inner wall of the force-relieving plate. Before the irregular block comes into contact with the workpiece, the force-applying plate first comes into contact with the workpiece. As the irregular block continues to move, the force-applying plate moves relative to the irregular block. When the force-applying plate moves, it generates a thrust on the unloading plate, causing the unloading plate to rotate and generating pressure on the torsion spring.

[0010] Preferably, the moving component includes a torsion spring sleeved on the inner wall of the rotating rod, and a shaped rod slidably connected to the side wall of the rotating rod; During the secondary grinding of the workpiece, the triangular block contacts the rotating rod again when it resets, and exerts a pushing force on the rotating rod, causing the rotating rod to rotate under force and exert pressure on the torsion spring. During the rotation of the rotating rod, the irregular rod moves downward.

[0011] Preferably, the scraping assembly includes a scraper fixedly connected to the outer wall of the irregular rod, a sealing block slidably connected to the side wall of the irregular rod, a corrugated plate fixedly connected to the side wall of the sealing block, and a limiting block slidably connected to the side wall of the mechanical claw. When the shaped rod moves, it drives the scraper to move synchronously. During the movement of the scraper, it continuously contacts the side wall of the mechanical claw. When the shaped rod moves, it drives the sealing block and the corrugated plate to move synchronously. When the sealing block moves, it is resisted by the limiting block. At this time, the sealing block gradually unblocks the groove of the shaped rod and exerts pressure on the corrugated plate, causing the corrugated plate to contract under force. As the shaped rod continues to move, the sealing block exerts a pushing force on the limiting block, causing the limiting block to move.

[0012] The present invention has the following beneficial effects: (1) When the exposed position of the workpiece surface is polished, the mechanical claw drives the workpiece to move to the surface of the machine body, so that the moving plate moves due to the resistance of the machine body and generates a thrust on the force block, causing the force block to move. When the irregular block comes into contact with the workpiece, the irregular block moves relative to the force block. When the force block is about to stop moving, the force block comes into contact with the rotating plate and generates a thrust on the rotating plate. When the rotating plate is about to stop rotating, it restricts the irregular block. Through the above components, the workpiece reference coordinate system is not changed throughout the process, completely preventing the positioning error caused by workpiece displacement and re-alignment, and ensuring the dimensional consistency of subsequent polishing processes.

[0013] (2) Before the irregular block of the present invention comes into contact with the workpiece, the force plate first comes into contact with the workpiece. As the irregular block continues to move, the force plate moves relative to the irregular block. When the force plate moves, it generates a thrust on the spring. When the force plate moves, it comes into contact with the unloading plate. During the continuous movement of the force plate, it generates a thrust on the unloading plate, causing the unloading plate to rotate and generating pressure on the torsion spring, causing the torsion spring to be compressed. As the unloading plate continues to rotate, it comes into contact with the surface of the workpiece. Through the above components, the contact area between the irregular block and the workpiece is increased, local stress concentration is prevented, the workpiece is subjected to more uniform force, and the shape and position accuracy after grinding is guaranteed.

[0014] (3) When the workpiece is polished for the second time, the triangular block gradually resets. At this time, the mechanical claw does not clamp the workpiece. When the triangular block resets, it contacts the rotating rod again and generates a pushing force on the rotating rod, causing the rotating rod to rotate and exert pressure on the torsion spring. During the rotation of the rotating rod, the irregular rod moves downward. When the irregular rod moves, it drives the scraper to move synchronously. During the movement of the scraper, it continuously contacts the side wall of the mechanical claw and scrapes off the impurities on the side wall of the mechanical claw. Through the above components, hard impurities are removed in time, preventing scratches on the workpiece surface and indentations under clamping pressure, and improving the accuracy and consistency of subsequent polishing and assembly processes.

[0015] (4) When the irregular rod moves, it drives the sealing block and the corrugated plate to move synchronously. When the sealing block moves, it is resisted by the limiting block, causing the sealing block to move relative to the irregular rod. At this time, the sealing block gradually unblocks the groove of the irregular rod and exerts pressure on the corrugated plate, causing the corrugated plate to shrink under force. When the sealing block can no longer move relative to the irregular rod, as the irregular rod continues to move, the sealing block exerts a thrust on the limiting block, causing the limiting block to move. At this time, when the scraper contacts the side wall of the mechanical claw, the scraped impurities fall directly into the interior of the irregular rod. Through the above components, the fallen impurities are collected to prevent the workpiece from being scratched or damaged, and to ensure the smoothness and processing accuracy of the workpiece surface.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1-8 This invention relates to a surface treatment device for welded structural components in a battery swapping station, comprising a body 13, a robotic arm 14 rotatably mounted on the top of the outer wall of the body 13, a grinding machine 15 fixedly mounted on the top of the outer wall of the body 13, and a robotic claw 16 rotatably mounted on the top of the outer wall of the robotic arm 14, and further comprising: Braking mechanism 1 is slidably disposed at the bottom of the outer wall of mechanical claw 16; The braking mechanism 1 includes a movable plate 111 that is slidably connected to the bottom of the outer wall of the mechanical claw 16, and a force-bearing block 112 that is slidably connected to the bottom of the outer wall of the mechanical claw 16. Protection mechanism 2 is slidably disposed on the outer wall of braking mechanism 1; Among them, the protection mechanism 2 includes a triangular block 221 that is slidably connected to the bottom of the outer wall of the force block 112, and a rotating rod 222 that is rotatably connected to the bottom of the outer wall of the mechanical claw 16; Cleaning mechanism 3 is fixedly installed on the outer wall of protection mechanism 2.

[0021] Braking mechanism 1 includes: Force-receiving component 11 is slidably disposed at the bottom of the outer wall of the mechanical claw 16; Fixing component 12 is fixedly disposed on the side wall of force-bearing component 11; The process involves the operator activating the robotic arm 14, which in turn drives the robotic gripper 16 to clamp the workpiece. Simultaneously, the grinder 15 is activated. Once the robotic gripper 16 has secured the workpiece, the robotic arm 14 begins to rotate, bringing the robotic gripper 16 closer to the grinder 15. At this point, the workpiece comes into contact with the grinder 15. Under the rotation of the output end of the grinder 15, the surface of the workpiece is ground. When the exposed area of ​​the workpiece surface is finished being ground, the robotic gripper 16 moves the workpiece to the surface of the machine body 13. At this point, the machine body 13 comes into contact with the force-bearing component 11. As the robotic gripper 16 continues to move, the machine body 13 exerts an external force on the force-bearing component 11, causing the force-bearing component 11 to move under the force. The fixing component 12 moves along with the force-bearing component 11.

[0022] Protection agency 2 includes: Contact component 21 is slidably disposed on the outer wall of force-bearing component 11; The movable component 22 is slidably disposed on the outer wall of the force-bearing component 11; When the force-receiving component 11 comes into contact with the workpiece, the contact component 21 is pushed by the force-receiving component 11, which forces the contact component 21 to move, and the moving component 22 moves synchronously with the force-receiving component 11.

[0023] Cleaning facility 3 includes: Scraping component 31 is fixedly installed on the outer wall of the movable component 22; When the moving component 22 moves, it drives the scraping component 31 to move synchronously. When the scraping component 31 comes into contact with the mechanical claw 16, it is resisted by the mechanical claw 16 and moves again.

[0024] Example 2, please refer to Figures 4-10 The present invention is a surface treatment device for welded structural components of a battery swapping station. Based on the first embodiment, the force-bearing component 11 includes a shaped block 113 that is slidably connected to the inner wall of the force-bearing block 112. When the exposed area of ​​the workpiece surface is finished, the mechanical claw 16 moves the workpiece to the surface of the machine body 13. At this time, the machine body 13 comes into contact with the moving plate 111. As the mechanical claw 16 continues to move, the moving plate 111 is resisted by the machine body 13 and moves. When the moving plate 111 moves, it generates a pushing force on the force block 112 through the inclined surface of the force block 112, causing the force block 112 to move under force. The irregular block 113 moves along with the force block 112.

[0025] The fixing component 12 includes a spring 121 fixedly connected to the side wall of the force-bearing block 112, a spring piece 122 fixedly connected to the inner wall of the force-bearing block 112, and a rotating plate 123 rotatably connected to the bottom of the outer wall of the mechanical claw 16. When the force-bearing block 112 moves, it exerts pressure on the spring 121, causing the spring 121 to compress and accumulate potential energy. The spring piece 122 moves synchronously with the force-bearing block 112. When the irregularly shaped block 113 comes into contact with the workpiece, as the force-bearing block 112 continues to move, the irregularly shaped block 113 exerts pressure on the spring piece 122, causing the spring piece 122 to compress and accumulate potential energy. At this time, the irregularly shaped block 113 moves relative to the force-bearing block 112. When the force-bearing block 112 is about to stop moving, it comes into contact with the rotating plate 123 and exerts a pushing force on the rotating plate 123, causing the rotating plate 123 to rotate and exert pressure on its own torsion spring. Figure 5 As shown, when the rotating plate 123 is about to stop rotating, it contacts several grooves at point E of the irregular block 113 and completes docking with the grooves. The rotating plate 123 completes the restriction of the irregular block 113, preventing the irregular block 113 from shifting during the subsequent rotation of the mechanical claw 16. At this time, the moving plate 111 does not contact the inclined surface of the force block 112 and extends to the other side of the mechanical claw 16. When the irregular block 113 completes the fixation of the workpiece, the mechanical claw 16 loses its grip on the workpiece, exposing the surface of the workpiece that was originally gripped by the mechanical claw 16. The mechanical claw 16 then drives the workpiece to contact the grinding machine 15 again to complete the grinding.

[0026] The contact component 21 includes a force-applying plate 211 that is slidably connected to the inner wall of the irregular block 113. A spring piece 212 is fixedly connected to the top of the outer wall of the force-applying plate 211. Several force-relieving plates 213 are rotatably connected to the outer wall of the irregular block 113. A torsion spring 214 is sleeved on the inner wall of the force-relieving plate 213. Before the irregularly shaped block 113 contacts the workpiece, the force-applying plate 211 first contacts the workpiece. As the irregularly shaped block 113 continues to move, the force-applying plate 211 moves relative to the irregularly shaped block 113. When the force-applying plate 211 moves, it generates a pushing force on the spring piece 212, causing the spring piece 212 to be compressed and accumulate potential energy, such as... Figure 6 As shown, when the force-applying plate 211 moves, it contacts the protrusion at point F of the unloading plate 213. During the continuous movement of the force-applying plate 211, the force-applying plate 211 generates a pushing force on the unloading plate 213, causing the unloading plate 213 to rotate under force and exert pressure on the torsion spring 214, causing the torsion spring 214 to be compressed and accumulate potential energy. As the unloading plate 213 continues to rotate, it eventually contacts the surface of the workpiece.

[0027] The movable component 22 includes a torsion spring 223 sleeved on the inner wall of the rotating rod 222, and a shaped rod 224 slidably connected to the side wall of the rotating rod 222. When the force-bearing block 112 moves, it drives the triangular block 221 to move synchronously. When the triangular block 221 moves a certain distance, it comes into contact with the rotating rod 222. At this time, the irregular rod 224 is at the top, so the triangular block 221 cannot exert a pushing force on the rotating rod 222. When the triangular block 221 comes into contact with the rotating rod 222, it is resisted by the rotating rod 222, which forces the rotating rod 222 to exert a pushing force on the inclined surface of the triangular block 221. The triangular block 221 moves upward under the force and applies pressure to the spring at its top. It then follows the force-bearing block 112 through the rotating rod 222. When the secondary grinding of the workpiece is completed, the mechanical gripper 16 drives the workpiece to move. When the machine moves to the finished product placement area, the machine body 13 contacts the other side of the moving plate 111. As the mechanical gripper 16 continues to move, the machine body 13 again exerts a pushing force on the moving plate 111, causing the force block 112 to lose the restriction of the moving plate 111 and begin to reset under the elastic force of the spring 121. The triangular block 221 also resets. At this time, the mechanical gripper 16 does not clamp the workpiece. When the triangular block 221 resets, it contacts the rotating rod 222 again and exerts a pushing force on the rotating rod 222, causing the rotating rod 222 to rotate under force and exert pressure on the torsion spring 223, causing the torsion spring 223 to be compressed and accumulate potential energy. Figure 7 As shown, during the rotation of the rotating rod 222, the irregular rod 224 is restricted by the through slot at point G of the mechanical claw 16, causing the irregular rod 224 to move downward.

[0028] The scraping assembly 31 includes a scraper 311 fixedly connected to the outer wall of the shaped rod 224, a sealing block 312 slidably connected to the side wall of the shaped rod 224, a corrugated plate 313 fixedly connected to the side wall of the sealing block 312, and a limiting block 314 slidably connected to the side wall of the mechanical claw 16. When the irregular rod 224 moves, it drives the scraper 311 to move synchronously. During the movement of the scraper 311, it continuously contacts the side wall of the mechanical claw 16 and scrapes away impurities from the side wall of the mechanical claw 16. When the irregular rod 224 moves, it drives the sealing block 312 and the corrugated plate 313 to move synchronously. When the sealing block 312 moves, it contacts the limiting block 314 and is resisted by the limiting block 314, causing the sealing block 312 to move relative to the irregular rod 224. At this time, the sealing block 312 gradually releases the obstruction of the irregular rod. The shaped rod 224 seals the groove and puts pressure on the corrugated plate 313, causing the corrugated plate 313 to contract under force and put pressure on the spring on its inner wall. When the sealing block 312 cannot move relative to the shaped rod 224, as the shaped rod 224 continues to move, the sealing block 312 pushes the limiting block 314, causing the limiting block 314 to move and put pressure on the spring at its rear end. At this time, when the scraper 311 contacts the side wall of the mechanical claw 16, the scraped impurities fall directly into the interior of the shaped rod 224.

[0029] One specific application of this embodiment is as follows: The operator starts the robotic arm 14, which drives the robotic claw 16 to clamp the workpiece. At the same time, the grinder 15 is started. When the robotic claw 16 confirms that the workpiece is fixed, the robotic arm 14 starts to rotate, which drives the robotic claw 16 to approach the grinder 15. At this time, the workpiece comes into contact with the grinder 15. Under the rotation of the output end of the grinder 15, the surface of the workpiece is ground.

[0030] When the robotic arm 14 drives the workpiece for grinding, the contact surface between the robotic gripper 16 and the workpiece becomes a grinding blind spot due to the tight fit between them. If the clamping contact surface of the welded structural component of the battery swapping station is an assembly mating surface, the remaining un-grinded allowance will directly cause the part to fail to be accurately inserted into the corresponding mounting position, resulting in assembly jamming and excessive fit gaps. When the existing equipment changes the clamping point, a certain offset will occur during the movement of the workpiece, which will affect the grinding accuracy. When the exposed part of the workpiece surface is ground, the robotic gripper 16 moves the workpiece to the surface of the machine body 13. At this time, the machine body 13 comes into contact with the moving plate 111. As the robotic gripper 16 continues to move, the moving plate 111 is resisted by the machine body 13 and moves. When the moving plate 111 moves, it is subjected to force. The inclined surface of block 112 exerts a pushing force on the force-bearing block 112, causing it to move. The irregularly shaped block 113 moves along with the force-bearing block 112. As the force-bearing block 112 moves, it exerts pressure on the spring 121, causing it to compress and accumulate potential energy. The spring piece 122 moves synchronously with the force-bearing block 112. When the irregularly shaped block 113 contacts the workpiece, the continued movement of the force-bearing block 112 causes it to exert pressure on the spring piece 122, compressing it and accumulating potential energy. At this point, the irregularly shaped block 113 moves relative to the force-bearing block 112. Just as the force-bearing block 112 is about to stop moving, it contacts the rotating plate 123 and exerts a pushing force on it, causing the rotating plate 123 to rotate and exert pressure on its own torsion spring. Figure 5 As shown, when the rotating plate 123 is about to stop rotating, it contacts several grooves at point E of the irregular block 113 and completes docking with the grooves. The rotating plate 123 completes the restriction of the irregular block 113, preventing the irregular block 113 from shifting during the subsequent rotation of the mechanical claw 16. At this time, the moving plate 111 does not contact the inclined surface of the force block 112 and extends to the other side of the mechanical claw 16. When the irregular block 113 completes the fixation of the workpiece, the mechanical claw 16 loses its grip on the workpiece, exposing the surface of the workpiece that was originally gripped by the mechanical claw 16. The mechanical claw 16 then drives the workpiece to contact the grinding machine 15 again to complete the grinding. Through the above components, the workpiece reference coordinate system is not changed throughout the process, completely preventing the positioning error caused by workpiece displacement and re-alignment, ensuring the dimensional consistency of subsequent grinding processes, and significantly reducing the scrap rate.

[0031] Utilizing the characteristics of the movement of the irregularly shaped block 113, before the irregularly shaped block 113 contacts the workpiece, the force-applying plate 211 first contacts the workpiece. As the irregularly shaped block 113 continues to move, the force-applying plate 211 moves relative to the irregularly shaped block 113. When the force-applying plate 211 moves, it generates a pushing force on the spring sheet 212, causing the spring sheet 212 to be compressed and accumulate potential energy. Figure 6 As shown, when the force-applying plate 211 moves, it contacts the protrusion at point F of the unloading plate 213. During the continuous movement of the force-applying plate 211, the force-applying plate 211 generates a pushing force on the unloading plate 213, causing the unloading plate 213 to rotate under force and exert pressure on the torsion spring 214, causing the torsion spring 214 to be compressed and accumulate potential energy. As the unloading plate 213 continues to rotate, it eventually contacts the surface of the workpiece. During the grinding process, residual stress and slight plastic deformation will be generated on the surface of the workpiece, and the overall structural rigidity will be significantly reduced compared to the unprocessed blank surface. At this time, when the irregular block 113 contacts the ground surface of the workpiece, a certain pressure will be generated, which will directly leave indentations on the ground high-precision surface, destroying the original surface finish. It may also cause local concave deformation of the workpiece, resulting in dimensional deviations. Through the above components, the contact area between the irregular block 113 and the workpiece is increased. At this time, the larger contact area can distribute the clamping force to a wider area, prevent local stress concentration, make the overall force on the workpiece more uniform, and ensure the dimensional and positional accuracy after grinding.

[0032] Utilizing the characteristics of the movement of the aforementioned force-bearing block 112, when the force-bearing block 112 moves, it drives the triangular block 221 to move synchronously. When the triangular block 221 moves a certain distance, it comes into contact with the rotating rod 222. At this time, the irregular rod 224 is at its top, preventing the triangular block 221 from generating a pushing force on the rotating rod 222. When the triangular block 221 comes into contact with the rotating rod 222, it is resisted by the rotating rod 222, forcing the rotating rod 222 to generate a pushing force on the inclined surface of the triangular block 221. The triangular block 221 moves upward under the force and applies pressure to the spring at its top, and follows the force-bearing block 112 through the rotating rod 222. When the secondary grinding of the workpiece is completed, the mechanical gripper 1... 6. The machine body 13 moves to the finished product placement area. At this time, the machine body 13 contacts the other side of the moving plate 111. As the mechanical gripper 16 continues to move, the machine body 13 pushes the moving plate 111 again, causing the force block 112 to lose the restriction of the moving plate 111 and begin to reset under the elastic force of the spring 121. The triangular block 221 also resets. At this time, the mechanical gripper 16 does not clamp the workpiece. When the triangular block 221 resets, it contacts the rotating rod 222 again and pushes the rotating rod 222, causing the rotating rod 222 to rotate under force and exert pressure on the torsion spring 223, causing the torsion spring 223 to be compressed and accumulate potential energy. Figure 7As shown, during the rotation of the rotating rod 222, the irregular rod 224 moves downward under the constraint of the through slot at point G of the mechanical claw 16. When the irregular rod 224 moves, it drives the scraper 311 to move synchronously. During the movement of the scraper 311, it continuously contacts the side wall of the mechanical claw 16 and scrapes away the impurities on the side wall of the mechanical claw 16. Since the burrs and debris generated during the grinding process have sharp edges, they can easily adhere to the surface of the mechanical claw 16 under the pressure of clamping contact. Hard impurities will directly press indentations and scratches on the surface of the workpiece under the clamping pressure, leaving obvious defects and damaging the integrity of the workpiece appearance. Through the above components, hard impurities are removed in time, preventing scratches and indentations on the surface of the workpiece under clamping pressure, and improving the accuracy and consistency of subsequent grinding and assembly processes.

[0033] Utilizing the characteristics of the movement of the aforementioned irregular rod 224, when the irregular rod 224 moves, it drives the sealing block 312 and the corrugated plate 313 to move synchronously. As the sealing block 312 moves, it comes into contact with the limiting block 314 and experiences resistance from the limiting block 314, causing the sealing block 312 to move relative to the irregular rod 224. At this time, the sealing block 312 gradually releases the seal on the groove of the irregular rod 224 and exerts pressure on the corrugated plate 313, causing the corrugated plate 313 to contract under force and exert pressure on the spring on its inner wall. When the sealing block 312 can no longer move relative to the irregular rod 224, as the irregular rod 224 continues to move, the sealing block 312 exerts a pushing force on the limiting block 314, causing the limiting block 314 to move and exert pressure on the spring at its rear end. At this time, the scraper 311... When the side wall of the mechanical gripper 16 contacts, the scraped impurities fall directly into the interior of the shaped rod 224. During the process of placing the workpiece, the scraper 311 scrapes off the impurities attached to the surface of the mechanical gripper 16. At this time, the fallen impurities will scatter on the surface of the polished workpiece, scratching the polished surface and damaging the appearance accuracy of the workpiece. They may even become stress concentration points in subsequent processes. The above-mentioned components collect the fallen impurities to prevent the workpiece from being scratched or damaged, and ensure the smoothness and processing accuracy of the workpiece surface. When the shaped rod 224 cannot move, the triangular block 221 can no longer push the rotating rod 222, causing the triangular block 221 to move again under the force. The rotating rod 222 is reset under the elastic force of the torsion spring 223, which drives the shaped rod 224 to reset.
