Description

Technical Field

[0001] This invention belongs to the field of display screen processing technology, specifically relating to an integrated processing device for grinding and polishing the edges and corners of a display screen. Background Technology

[0002] With the rapid development of electronic information technology, displays, as the core component of human-computer interaction, have been widely used in various electronic products such as smartphones, tablets, laptops, smart wearable devices, and in-vehicle display terminals. Consumers' requirements for the appearance, safety, and display effect of displays are constantly increasing. Among these, the quality of the edge and corner treatment of the display directly affects the overall quality and market competitiveness of the product. In the display manufacturing industry, the grinding process is mainly used to remove burrs from the edges and corners and to shape the edges and corners so that the edges and corners form a preset rounded or beveled structure. The polishing process is used to further reduce the surface roughness of the edges and corners, improve the surface smoothness, and make the edges and corners present a delicate and smooth texture.

[0003] The existing edge grinding and surface polishing of displays mostly adopt a separate processing mode, which has many significant limitations. First, the step-by-step processing requires two sets of independent equipment and workstations. The workpiece needs to be transferred and repositioned multiple times between different equipment, which not only prolongs the production cycle but also reduces the overall processing efficiency. In addition, for displays with curved surfaces, the existing equipment is difficult to achieve the ideal processing effect during the grinding process and cannot meet the processing requirements of curved surfaces. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an integrated processing device for grinding and polishing the edges and corners of a display screen.

[0005] The technical solution adopted to solve the above technical problems is: an integrated processing device for grinding and polishing the edges of a display screen, including a mounting box, a plurality of support columns fixedly installed at the bottom of the mounting box, and grinding components installed inside the mounting box; The top of the mounting box is equipped with a clamping and rotating assembly, and the top of the mounting box is fixedly connected to a mounting frame, on which a clamping and polishing assembly is mounted. The top of the mounting box has a processing groove, and the display screen body is mounted on the clamping and rotating assembly.

[0006] Furthermore, the grinding assembly includes a first rotating rod rotatably connected inside the mounting box. Adjustment grooves are provided at both the front and rear ends of the inner wall of the mounting box. A second rotating rod is slidably installed between the two adjustment grooves. A transmission wheel is fixedly installed on the outer wall of the first rotating rod, and a transmission wheel is rotatably installed on the outer wall of the second rotating rod. A grinding belt is provided between the two transmission wheels. Guide rods are fixedly connected inside each of the two adjustment grooves, and both guide rods pass through both the front and rear ends of the second rotating rod. Springs are slidably installed on the outer walls of both guide rods. A first motor is fixedly installed at the front end of the mounting box.

[0007] With the above technical solution, the first motor is started, which drives the first rotating rod to rotate. The first rotating rod drives the grinding belt to rotate in a cycle through the transmission wheel on it. At the same time, the grinding belt drives the transmission wheel on the second rotating rod to rotate synchronously, so as to realize continuous grinding. During the grinding process, the second rotating rod can slide along the adjustment groove and the guide rod. The spring sleeved on the outer wall of the guide rod always applies an elastic thrust to the second rotating rod, so that the grinding belt is kept in a constant tension state, avoiding the grinding belt from loosening and ensuring that the grinding force is uniform and stable.

[0008] Furthermore, the clamping and rotating assembly includes a first mounting slot and a second mounting slot formed on the top of the mounting box. First limiting slots are formed on both sides of the inner wall of the first mounting slot. A linkage plate is slidably installed between the two first limiting slots. A first hydraulic cylinder is fixedly installed on the top of the mounting box. The output end of the first hydraulic cylinder is fixedly connected to the rear end of the linkage plate. An electric motor is fixedly installed on the upper side of the rear end of the linkage plate. A transmission rod is fixedly installed on the output end of the electric motor. A transmission gear is fixedly connected to the outer wall of the transmission rod. A rotating column is rotatably connected to the front end of the linkage plate. The rear end of the outer wall of the rotating column is fixedly connected to... The device has multiple transmission racks, and the front end of the rotating column has multiple anti-slip grooves. A fixing block is fixedly connected to the front end of the inner wall of the second mounting groove, and a connecting plate is fixedly connected to the rear end of the fixing block. A T-shaped groove is opened inside the connecting plate, and multiple balls are rotatably installed inside the T-shaped groove. A rotating component is rotatably connected to the inner wall of the T-shaped groove, and a rubber pad is fixedly connected to the rear end of the rotating component. Multiple negative pressure holes are opened between the rotating component and the rubber pad. A hydraulic rod is fixedly installed on the top of the fixing block, and a U-shaped connector is fixedly connected to the output end of the hydraulic rod. Multiple rollers are rotatably installed between the inner walls of the U-shaped connector.

[0009] Using the above technical solution, the display screen body to be processed is placed on the grinding belt in the second mounting groove for initial positioning. Then, the first hydraulic cylinder is activated, pushing the linkage plate forward along the first limiting groove, causing the rotating column to approach the side of the display screen body. The anti-slip groove at the front end of the rotating column contacts one side of the display screen body, while the rubber pad at the rear end of the rotating component abuts against the display screen body from the other side. The rubber pad generates negative pressure suction through negative pressure holes, which, combined with the anti-slip clamping of the rotating column, achieves stable clamping of the display screen body. If the clamping angle needs adjustment, the electric motor can be activated, driving the transmission gear to rotate via the transmission rod. The transmission gear interacts with the outer edge of the rotating column... The drive rack and pinion of the wall engage, driving the rotating column to rotate, thereby causing the display screen body to rotate synchronously to the target angle. At this time, the hydraulic rod is activated, pushing the U-shaped connector downward, so that multiple rollers on the inner wall of the U-shaped connector contact and squeeze the polishing belt. Then the rollers continue to press down on the polishing belt, counteracting the upward elasticity of the polishing belt itself, preventing the polishing belt from excessively lifting the display screen body, and preventing the display screen from being damaged due to excessive force. During the polishing operation, the hydraulic rod maintains a constant pressure to ensure that the rollers always keep in contact with the polishing belt and continuously buffer the elasticity of the polishing belt. Then the drive mechanism of the polishing belt is activated, which works with the polishing components below to polish the display screen body.

[0010] Furthermore, each of the multiple transmission racks meshes with a transmission gear, and the length of the transmission gear is equal to the length of the multiple transmission racks.

[0011] The above technical solution can distribute the driving force of the electric motor to multiple contact points of the rotating column, rather than being subjected to force at a single location. This design can prevent the transmission rack from wearing and deforming due to excessive local force, while making the torque on the rotating column more balanced, and making it less prone to jamming or deviation during rotation, thus ensuring the clamping stability of the display screen body.

[0012] Furthermore, the rear ends of the plurality of balls are all in contact with the front end of the rotating component, and the rotating component is matched with the T-groove.

[0013] With the above technical solution, compared with the direct sliding contact between the rotating part and the inner wall of the T-slot, the rolling of the ball can significantly reduce the coefficient of friction, reduce the resistance and wear during rotation, and make the angle adjustment of the display screen smoother. In addition, the matching between the two ensures that the rotation axis of the rotating part is completely aligned with the connecting plate, avoiding eccentric swing during rotation. This protects the edge of the display screen from being squeezed and damaged, and ensures the accuracy of the grinding angle.

[0014] Furthermore, the clamping and polishing assembly includes a second hydraulic cylinder fixedly mounted on the top of the mounting frame. A T-shaped sliding rod is slidably mounted on the bottom of the second hydraulic cylinder. A mounting box is fixedly connected to the bottom of the T-shaped sliding rod. A protective plate is fixedly connected to the rear end of the bottom of the mounting box. A second limiting groove is opened at the front end of the protective plate. A second motor is fixedly mounted on one side of the outer wall of the mounting box. A bidirectional threaded rod is fixedly connected to the output end of the second motor. Two clamping plates are threadedly connected to the bidirectional threaded rod. Limiting plates are fixedly connected to the rear ends of both clamping plates. A third hydraulic cylinder is fixedly mounted on the rear end of the mounting frame. The output end of the third hydraulic cylinder is fixedly connected to the rear end of the mounting box. A third motor is fixedly mounted on one side of the mounting frame. A baffle is fixedly connected to the mounting frame. A lead screw is fixedly connected to the output end of the third motor. An assembly plate is threadedly connected to the lead screw. A rotating motor is mounted on the top of the assembly plate. A polishing disc is fixedly mounted on the rear end of the rotating motor.

[0015] Using the above technical solution, the second hydraulic cylinder of the clamping and polishing assembly is activated, pushing the T-shaped sliding rod downwards and causing the mounting box to descend. This aligns the two side edges of the display screen body with the area between the two clamping plates, and the limiting plate at the rear end of the clamping plate is embedded in the second limiting groove of the protective plate. The second motor is then activated, driving the bidirectional threaded rod to rotate. Since the threads of the two clamping plates and the bidirectional threaded rod rotate in opposite directions, they synchronously move towards the center until the inner sides are tightly fitted with the two sides of the display screen body. The limiting plate is confirmed to have slid into place along the second limiting groove, forming a lateral limit to prevent the workpiece from shifting left or right. The second motor is then turned off, completing the secure clamping of the display screen body. The second hydraulic cylinder of the clamping and polishing assembly is then activated again, slightly lifting the mounting box to release the display screen body from the clamp. The grinding belt of the rotating assembly completes the workpiece transfer. Then, the third hydraulic cylinder extends and retracts, pushing the mounting box and the clamped display screen body to move back and forth, so that the distance between the surface to be polished and the polishing disc is adapted. Then, the third motor is started, driving the lead screw to rotate. The assembly plate slides left and right along the direction of the lead screw, driving the rotating motor and the polishing disc to move, so that the center of the polishing disc is aligned with the center of the area to be polished. Then, the second hydraulic cylinder is started, slowly pushing the T-shaped sliding rod downward, so that the surface of the display screen to be polished makes light contact with the rear end of the polishing disc. At this time, the rotating motor is started, driving the polishing disc to rotate at high speed. After the speed stabilizes, the height can be finely adjusted by the second hydraulic cylinder to make the polishing disc and the surface to be polished form uniform pressure. After the polishing is up to standard, the rotating motor is turned off, and the polishing disc comes to a complete stop.

[0016] Furthermore, both of the limiting plates are fitted into the second limiting groove, and the two limiting plates are parallel to each other.

[0017] Through the above technical solution, the limiting plate and the second limiting groove are precisely matched, forming a stable guide for the clamping plate, so that the clamping plate can only move in a straight line along the second limiting groove, and there will be no lateral swaying, vertical warping or jamming, ensuring that the clamping action is stable and reliable.

[0018] The beneficial effects of the present invention are as follows: (1) The present invention solves the problem of traditional devices having difficulty processing arc surfaces by setting up a grinding component and a clamping rotation component. Through the continuous and precise angle adjustment of the clamping rotation component and the adaptive curvature of the grinding belt, the arc corners and curved screens can be ground without dead angles. At the same time, it can be adapted to displays of different sizes and corner specifications, thus expanding the processing range of the device. Furthermore, the flexible clamping design and the elastic buffering mechanism of the grinding belt can prevent brittle material displays from being crushed, scratched, or broken, thereby reducing workpiece loss during processing and lowering production costs. (2) The present invention sets up a clamping polishing component, which forms an automated linkage with the previous grinding and clamping rotation components. The workpiece does not need to be manually transferred and positioned twice. It can directly complete the entire process of receiving and polishing after grinding, reducing manual intervention and process intervals, greatly improving the efficiency of integrated processing, and adapting to large-scale mass production.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] like Figure 1 - Figure 10As shown, this embodiment of an integrated processing device for grinding and polishing the edges of a display screen includes a mounting box 1. Multiple support columns 2 are fixedly mounted on the bottom of the mounting box 1. A grinding assembly 3 is installed inside the mounting box 1. The grinding assembly 3 includes a first rotating rod 301 rotatably connected inside the mounting box 1. Adjustment grooves 305 are provided at both the front and rear ends of the inner wall of the mounting box 1. A second rotating rod 302 is slidably mounted between the two adjustment grooves 305. A transmission wheel 303 is fixedly mounted on the outer wall of the first rotating rod 301. A transmission wheel 303 is rotatably mounted on the outer wall of the second rotating rod 302. A grinding belt 304 is provided between the two transmission wheels 303. Guide rods 306 are fixedly connected inside each of the two adjustment grooves 305, and both guide rods 306 pass through both the front and rear ends of the second rotating rod 302. Springs 307 are slidably mounted on the outer walls of both guide rods 306. A first motor 308 is fixedly mounted on the front end of the mounting box 1. When the first motor 308 is started, it drives the first rotating rod 301 to rotate. The first rotating rod 301 drives the grinding belt 304 to rotate cyclically through the transmission wheel 303 on it. At the same time, the grinding belt 304 drives the transmission wheel 303 on the second rotating rod 302 to rotate synchronously, so as to achieve continuous grinding. During the grinding process, the second rotating rod 302 can slide along the adjustment groove 305 and the guide rod 306. The springs 307 sleeved on the outer wall of the guide rod 306 always apply elastic thrust to the second rotating rod 302, so that the grinding belt 304 is kept in a constant tension state, preventing the grinding belt 304 from loosening and ensuring that the grinding force is uniform and stable.

[0023] like Figure 2 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, a clamping and rotating assembly 4 is installed on the top of the mounting box 1. The clamping and rotating assembly 4 includes a first mounting groove 401 and a second mounting groove 4021 opened on the top of the mounting box 1. A first limiting groove 402 is opened on both sides of the inner wall of the first mounting groove 401. A linkage plate 403 is slidably installed between the two first limiting grooves 402. A first hydraulic cylinder 404 is fixedly installed on the top of the mounting box 1. The output end of the first hydraulic cylinder 404 is fixedly connected to the rear end of the linkage plate 403. An electric motor 405 is fixedly installed on the upper side of the rear end of the linkage plate 403. A transmission rod 406 is fixedly installed on the output end of the electric motor 405. A transmission gear 407 is fixedly connected to the outer wall of the transmission rod 406. A rotating column 408 is rotatably connected to the front end of the linkage plate 403. Multiple transmission racks 407 are fixedly connected to the rear end of the outer wall of the rotating column 408. 9. The front end of the rotating column 408 is provided with multiple anti-slip grooves 4010. The front end of the inner wall of the second mounting groove 4021 is fixedly connected to a fixing block 4011. The rear end of the fixing block 4011 is fixedly connected to a connecting plate 4012. The connecting plate 4012 is provided with a T-shaped groove 4013. Multiple balls 4014 are rotatably installed inside the T-shaped groove 4013. A rotating component 4015 is rotatably connected to the inner wall of the T-shaped groove 4013. A rubber pad 4016 is fixedly connected to the rear end of the rotating component 4015. Multiple negative pressure holes 4017 are provided between the rotating component 4015 and the rubber pad 4016. A hydraulic rod 4018 is fixedly installed on the top of the fixing block 4011. A U-shaped connector 4019 is fixedly connected to the output end of the hydraulic rod 4018. Multiple rollers 4020 are rotatably installed between the inner walls of the U-shaped connector 4019.The display screen body 8 to be processed is placed on the grinding belt 304 in the second mounting groove 4021 for initial positioning. Then, the first hydraulic cylinder 404 is activated, pushing the linkage plate 403 to slide forward along the first limiting groove 402, so that the rotating column 408 is close to one side of the display screen body 8, and the anti-slip groove 4010 at the front end of the rotating column 408 contacts one side of the display screen body 8. At the same time, the rubber pad 4016 at the rear end of the rotating component 4015 abuts against the display screen body 8 from the other side. The rubber pad 4016 generates negative pressure adsorption force through the negative pressure hole 4017, which, together with the anti-slip clamping of the rotating column 408, completes the stable clamping of the display screen body 8. If it is necessary to adjust the clamping angle, the cylinder can be activated. An electric motor 405 drives a transmission gear 407 to rotate via a transmission rod 406. The transmission gear 407 meshes with a transmission rack 409 on the outer wall of a rotating column 408, driving the rotating column 408 to rotate. This causes the display screen body 8 to rotate synchronously to the target angle. At this time, the hydraulic rod 4018 is activated, pushing the U-shaped connector 4019 downward. This causes multiple rollers 4020 on the inner wall of the U-shaped connector 4019 to contact and press against the polishing belt 304. The rollers 4020 then continue to press down on the polishing belt 304, counteracting the upward elasticity of the polishing belt 304 itself. This prevents the polishing belt 304 from excessively lifting the display screen body 8 and avoids damage to the display screen due to excessive force. This is the polishing operation process. In the process, the hydraulic rod 4018 maintains constant pressure, ensuring that the roller 4020 always adheres to the grinding belt 304, continuously buffering the elasticity of the grinding belt 304. Then, the drive mechanism of the grinding belt 304 is activated, cooperating with the grinding assembly 3 below to grind the display screen body 8. Multiple transmission racks 409 mesh with transmission gears 407, and the length of the transmission gears 407 is equal to the length of the multiple transmission racks 409. This design can distribute the driving force of the electric motor 405 to multiple contact points of the rotating column 408, rather than being subjected to force at a single location. This design can prevent the transmission racks 409 from wearing and deforming due to excessive local force, while also ensuring that the torque received by the rotating column 408 is evenly distributed. More balanced rotation, less prone to jamming or shifting, ensuring the clamping stability of the display body 8. The rear ends of multiple ball bearings 4014 are all in contact with the front end of the rotating component 4015, and the rotating component 4015 matches the T-slot 4013. Compared to the rotating component 4015 directly sliding against the inner wall of the T-slot 4013, the rolling of the ball bearings 4014 significantly reduces the coefficient of friction, decreasing resistance and wear during rotation, making the angle adjustment of the display smoother. Furthermore, the matching ensures that the rotation axis of the rotating component 4015 completely coincides with the connecting plate 4012, preventing eccentric wobbling during rotation. This protects the edges of the display from being squeezed and damaged, while also ensuring the accuracy of the grinding angle.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9As shown, a mounting frame 5 is fixedly connected to the top of the mounting box 1, and a clamping and polishing assembly 6 is mounted on the mounting frame 5. A processing groove 7 is opened on the top of the mounting box 1. A display screen body 8 is mounted on the clamping and rotating assembly 4. The clamping and polishing assembly 6 includes a second hydraulic cylinder 601 fixedly mounted on the top of the mounting frame 5. A T-shaped sliding rod 602 is slidably mounted on the bottom of the second hydraulic cylinder 601. A mounting box 603 is fixedly connected to the bottom of the T-shaped sliding rod 602. A protective plate 604 is fixedly connected to the rear end of the bottom of the mounting box 603. A second limiting groove 605 is opened at the front end of the protective plate 604. A second motor 606 is fixedly mounted on one side of the outer wall of the mounting box 603. A double-ended motor 606 is fixedly connected to the output end of the second motor 606. Two clamping plates 608 are threaded onto the threaded rod 607. Limiting plates 609 are fixedly connected to the rear ends of both clamping plates 608. A third hydraulic cylinder 6010 is fixedly installed at the rear end of the mounting frame 5. The output end of the third hydraulic cylinder 6010 is fixedly connected to the rear end of the mounting box 603. A third motor 6011 is fixedly installed on one side of the mounting frame 5. A baffle 6012 is fixedly connected to the mounting frame 5. A lead screw 6013 is fixedly connected to the output end of the third motor 6011. An assembly plate 6014 is threaded onto the lead screw 6013. A rotary motor 6015 is installed on the top of the assembly plate 6014. A polishing disc 6016 is fixedly installed at the rear end of the rotary motor 6015.The second hydraulic cylinder 601 of the clamping and polishing assembly 6 is activated, pushing the T-shaped sliding rod 602 downward and causing the mounting box 603 to descend. This aligns the two side edges of the display screen body 8 with the area between the two clamping plates 608, and the limiting plate 609 at the rear end of the clamping plate 608 is embedded in the second limiting groove 605 of the protective plate 604. The second motor 606 is then activated, causing the bidirectional threaded rod 607 to rotate. Since the threads of the two clamping plates 608 and the bidirectional threaded rod 607 rotate in opposite directions, they move towards the center synchronously until their inner sides are tightly fitted against the two sides of the display screen body 8. After confirming that the limiting plate 609 slides into place along the second limiting groove 605 to form a lateral limit and prevent the workpiece from shifting left or right, the second motor 606 is turned off to securely hold the display screen body 8. The second hydraulic cylinder 601 of the clamping and polishing assembly 6 is then activated again to slightly lift the mounting box 603, causing the display screen body 8 to disengage from the polishing belt 304 of the clamping and rotating assembly 4, completing the workpiece transfer. Subsequently, the third hydraulic cylinder 6010 is extended and retracted to push the mounting box 603 and the clamped display screen body 8 to move back and forth, so that the distance between the surface to be polished and the polishing disc 6016 is appropriate. Then, the third motor 6011 is started, driving the lead screw 6013 to rotate. The assembly plate 6014 slides left and right along the direction of the lead screw 6013, driving the rotary motor 6015 and the polishing disc 6016 to move, so that the center of the polishing disc 6016 is aligned with the center of the area to be polished. Then, the second hydraulic cylinder 601 is started, slowly pushing the T-shaped sliding rod 602 downward, so that the surface of the display screen to be polished makes light contact with the rear end of the polishing disc 6016. At this time, the rotary motor 6015 is started, driving the polishing disc 6016 to rotate at high speed. After the speed stabilizes, the second hydraulic cylinder can be used to rotate the polishing disc 6016. 601 Fine-tunes the vertical height to ensure uniform pressure between the polishing disc 6016 and the surface to be polished. After polishing reaches the required standard, the rotating motor 6015 is turned off. Once the polishing disc 6016 is completely stationary, both limiting plates 609 are engaged with the second limiting groove 605, and the two limiting plates 609 are parallel to each other. The precise engagement of the limiting plates 609 and the second limiting groove 605 provides stable guidance for the clamping plate 608, ensuring that the clamping plate 608 can only move linearly along the second limiting groove 605, preventing lateral swaying, vertical warping, or jamming, thus ensuring smooth and reliable clamping action.

[0025] The working principle of this embodiment is as follows: The display screen body 8 to be processed is placed on the grinding belt 304 in the second mounting groove 4021 to complete the initial positioning. Then, the first hydraulic cylinder 404 is started, pushing the linkage plate 403 to slide forward along the first limiting groove 402, so that the rotating column 408 is close to one side of the display screen body 8, and the anti-slip groove 4010 at the front end of the rotating column 408 contacts one side of the display screen body 8. At the same time, the rubber pad 4016 at the rear end of the rotating component 4015 abuts against the display screen body 8 from the other side. The rubber pad 4016 generates negative pressure adsorption force through the negative pressure hole 4017, which, together with the anti-slip clamping of the rotating column 408, completes the stable clamping of the display screen body 8. If it is necessary to adjust the clamping angle, the electric motor 405 can be started, which drives the transmission gear 407 to rotate through the transmission rod 406. The transmission gear 407 and the rotating component 405 can be adjusted. The transmission rack 409 on the outer wall of the column 408 engages, driving the rotating column 408 to rotate, thereby driving the display screen body 8 to rotate synchronously to the target angle. At this time, the hydraulic rod 4018 is activated, pushing the U-shaped connector 4019 to move downward, so that multiple rollers 4020 on the inner wall of the U-shaped connector 4019 contact and squeeze the polishing belt 304. Then the rollers 4020 continue to press down on the polishing belt 304 to counteract the upward elasticity of the polishing belt 304 itself, preventing the polishing belt 304 from excessively lifting the display screen body 8 and preventing the display screen from being damaged due to excessive force. During the polishing operation, the hydraulic rod 4018 maintains constant pressure to ensure that the rollers 4020 always fit against the polishing belt 304 and continuously buffer the elasticity of the polishing belt 304. Then the drive mechanism of the polishing belt 304 is activated, and the polishing component 3 below is used to polish the display screen body 8. Then, the second hydraulic cylinder 601 of the clamping and polishing assembly 6 is activated, pushing the T-shaped sliding rod 602 downwards, causing the mounting box 603 to descend, aligning the two side edges of the display screen body 8 with the area between the two clamping plates 608, and ensuring that the limiting plate 609 at the rear end of the clamping plate 608 is embedded in the second limiting groove 605 of the protective plate 604. The second motor 606 is then activated, driving the bidirectional threaded rod 607 to rotate. Since the threads of the two clamping plates 608 and the bidirectional threaded rod 607 rotate in opposite directions, they synchronously move towards the center until their inner sides are tightly fitted with the sides of the display screen body 8. Once it is confirmed that the limiting plate 609 has slid into place along the second limiting groove 605, forming a lateral limit to prevent the workpiece from shifting left or right, the second motor 606 is turned off, completing the secure clamping of the display screen body 8. The second hydraulic cylinder 601 of the clamping and polishing assembly 6 is activated again, slightly lifting the mounting box 603 upwards, causing the display screen body 8 to disengage from the polishing belt 304 of the clamping and rotating assembly 4. The workpiece is transferred, and then the third hydraulic cylinder 6010 extends and retracts, pushing the mounting box 603 and the clamped display screen body 8 to move back and forth, so that the distance between the surface to be polished and the polishing disc 6016 is adapted. Then, the third motor 6011 is started, driving the lead screw 6013 to rotate. The assembly plate 6014 slides left and right along the direction of the lead screw 6013, driving the rotating motor 6015 and the polishing disc 6016 to move, so that the center of the polishing disc 6016 is aligned with the center of the area to be polished. Then, the second hydraulic cylinder 601 is started, slowly pushing the T-shaped sliding rod 602 downward, so that the surface to be polished of the display screen makes light contact with the rear end of the polishing disc 6016. At this time, the rotating motor 6015 is started, driving the polishing disc 6016 to rotate at high speed. After the speed stabilizes, the height can be finely adjusted by the second hydraulic cylinder 601 to make the polishing disc 6016 form uniform pressure with the surface to be polished. After the polishing is up to standard, the rotating motor 6015 is turned off, and the polishing disc 6016 is completely stationary.
