[0024] Referring to Figure 1 , Figure 2 and Figure 3 , a high-efficiency polishing machine is shown, comprising, a box structure 1, which is installed on the top of the conveyor frame, and the conveying belt conveying the materials passes through the box structure 1; a material stopping device 2, which is installed through the box structure 1, used to clamp the materials conveyed through the conveying belt; a polishing device 3, which is movably installed inside the box structure 1, a controller 4, which is connected to control the material stopping device 2 and the polishing device 3; an inspection device 5, which is installed outside the box structure 1, and the materials polished by the polishing device 3 pass through the inspection device 5 for surface inspection, and the inspection data is transmitted to the controller 4, so that the conveyor is driven to rotate by the controller 4, and the unqualified materials are re-fed into the box structure 1 for secondary polishing; A dust collection device 6 is installed on the top of the box structure 1 and cooperates with the polishing device 3 to complete self-cleaning.

[0025] As shown in Figure 3 and Figure 4 , the box structure 1 includes a box 11 and a side box cover 12, the front and rear ends of the box 11 are provided with through ports 13 through which the conveying belt passes, the top of the side of the box 11 is provided with an access opening 14, the side box cover 12 is detachably installed at the access opening 14, and an assembly groove 15 is arranged on the side of the box 11 away from the access opening 14.

[0026] The side cover 12 is detachable and is fixed to the box 11 by screws, and after being removed, the access opening 14 is opened to facilitate routine inspection and maintenance of the polishing device 3.

[0027] The box 11 is fixed to the rack of the conveyor by conventional fixing members such as screws.

[0028] As shown in Figure 3 , Figure 4 and Figure 5 , the stopping device 2 includes a driving clamping part 21 and a fixed clamping part 22, the fixed clamping part 22 is fixed to the side of the box 11 near the bottom, and the driving clamping part 21 is movably installed in the interior of the box 11, the moving direction of the driving clamping part 21 is perpendicular to the direction of the conveying belt, the driving clamping part 21 and the fixed clamping part 22 are at the same height, and the height is lower than the thickness of the workpiece to be polished.

[0029] The function of the stopping device 2 is to clamp the workpiece to be polished on both sides, so that the position of the workpiece is kept unchanged during polishing, and displacement of the workpiece caused by the polishing device 3 during polishing and polishing of the surface of the workpiece is avoided.

[0030] As shown in Figure 5 and Figure 7As shown, the active clamping part 21 comprises a clamping plate 210, a servo push rod 211, a pressure sensor 212 and an emitter 213; the clamping plate 210 is arranged on the inner side of the box body 11, two or more guide rods 214 are arranged in parallel on the side of the clamping plate 210 away from the fixed clamping part 22, a linear bearing 215 is installed on the box body 11 and is in sliding fit with the guide rods 214, a non-slip pad 216 is fixed on the end face of the clamping plate 210 away from the guide rods 214, the emitter 213 is embedded in the clamping plate 210 and emits a light beam towards the fixed clamping part 22, and the outer end face of the emitter 213 is lower than the working surface of the non-slip pad 216; the pressure sensor 212 is embedded in the clamping plate 210 and has a detection surface flush with the surface of the non-slip pad 216; the emitter 213, the pressure sensor 212 and the servo push rod 211 are all connected to the controller 4; the servo push rod 211 is fixed on the outer side of the box body 11, and the movable end of the servo push rod 211 penetrates through the wall of the box body 11 and is fixedly connected to the clamping plate 210.

[0031] In the above technical solution, the clamping plate 210 is actively clamped to the workpiece by the pushing of the servo push rod 211.

[0032] The emitter 213 is an infrared emitter, and infrared light is generated. When the light is blocked, it means that the workpiece is in place. At this time, the controller 4 controls the servo push rod 211 to push out the clamping plate 210.

[0033] The pressure sensor 212 detects the pressure when the clamping plate 210 clamps the workpiece. When the pressure reaches the preset value of the controller 4, the servo push rod 211 stops pushing out.

[0034] Referring to Figs. Figure 5 , Figure 6 and Figure 7 , the fixed clamping part 22 comprises a fixed seat 221, a pulley 222 and a receiver 223; the receiver 223 is embedded in the fixed seat 221 and corresponds to the emitter 213 to receive the light beam emitted from the emitter 213; the pulley 222 is rotatably installed in the fixed seat 221 by a bearing and partially protrudes to rollingly contact the workpiece; the controller 4 is also connected to the drive motor of the conveyor; when the workpiece is conveyed by the conveyor to between the emitter 213 and the receiver 223, the receiver 223 cannot receive the light beam. At this time, the controller 4 controls the conveyor to stop and synchronously controls the servo push rod 211 to eject, so as to complete the clamping of the workpiece by the clamping plate 210 and the fixed seat 221.

[0035] In the above technical solution, the pulley 222 rollingly supports the workpiece, and when the clamping plate 210 is pushed out, the workpiece is clamped between the pulley 222 and the clamping plate 210.

[0036] After the workpiece is polished, the clamping plate 210 retracts, and the conveyor resumes its movement, causing the workpiece to slide out along the pulley 222.

[0037] Receiver 223 is used to receive infrared light. When it cannot receive infrared light, it indicates that the workpiece is in place. At this time, controller 4 controls the servo push rod to push out.

[0038] See Figure 2 , Figure 3 , Figure 8 and Figure 9 As shown, the grinding device 3 includes a machine cover 31, a drive roller 32, a driven roller 33, a motor 34, a transmission unit 35, a slider 36, an adjusting screw 37, a first servo push rod 38, and a grinding belt 39. A side plate 310 is detachably mounted on one side of the machine cover 31 by screws. The side plate 310 corresponds to the side cover 12. A guide box 311 is provided at the bottom of the other side of the cover 31. The guide box 311 extends out through the mounting groove 15 and can only move along the vertical direction of the mounting groove 15. The active roller 32 is rotatably mounted inside the housing 31 via bearings, the motor 34 is fixedly mounted outside the housing 31, and the transmission unit 35 is installed between the motor 34 and the active roller 32; the slider 36 is slidably mounted inside the guide box 311, and the driven roller 33 is rotatably mounted on the slider 36 via bearings and parallel to the active roller 32; the grinding belt 39 is installed between the active roller 32 and the driven roller 33; the end of the slider 36 away from the driven roller 33 extends to the outside of the guide box 311, and a mounting bracket 312 is provided at the outer end face of the guide box 311; the adjusting screw 37 is rotatably mounted on the mounting bracket 312 via bearings; the side of the slider 36 is machined with a threaded hole 361 that matches the adjusting screw 37, and the threaded hole 361 is perpendicular to the axis of the driven roller 33; the first servo push rod 38 is fixedly mounted on the top of the housing 11, and the output end of the first servo push rod 38 passes through the... A pressure plate 381 is fixed inside the housing 11. Multiple guide rods 331 are provided on the top of the cover 31. The guide rods 331 pass upward through the pressure plate 381 and are threadedly engaged with limit caps 332. A spring 333 is sleeved on the guide rod 331. The spring 333 acts between the pressure plate 381 and the cover 31. The downward rotation position of the limit cap 332 is adjustable to adjust the compression amplitude of the spring 333. The motor 34 and the first servo push rod 38 are both connected to the controller 4.

[0039] In the above technical solution, the slider 36 is adjustable in position under the drive of the adjusting screw 37. When replacing the grinding belt 39, the slider 36 moves towards the drive roller 32, so that the grinding belt 39 is loosened, making it easy to disassemble and replace. After the replacement is completed, the adjusting screw 37 drives the slider 36 to move away from the drive roller 32 to tension the grinding belt 39.

[0040] The motor 34 provides driving force, and the transmission unit 35 (which is a synchronous toothed belt drive) drives the drive roller 32 to rotate actively, which in turn drives the grinding belt 39 to rotate at high speed. Part of the grinding belt 39 protrudes downward to the outside of the machine cover 31. The grinding belt 39 is used to grind the surface of the workpiece.

[0041] See Figure 2 and Figure 9 As shown, a horizontal stop bar 313 is provided inside the guide box 311. The horizontal stop bar 313 passes through the slider 36. Folding curtains 314 are installed on both sides of the slider 36. The end of the folding curtain 314 away from the slider 36 is fixed to the inner wall of the guide box 311. The horizontal stop bar 313 blocks the displacement of the folding curtain 314 towards the machine cover 31.

[0042] The above technical solution mainly uses the folding curtain 314 to block dust and prevent dust particles generated during the grinding and polishing process from leaking out from the guide box 311.

[0043] The crossbar 313 and the slider 36 are in clearance fit. Their function is to block the folding curtain 314 and prevent the folding curtain 314 from entering the machine cover 31 in the direction of the grinding belt 39.

[0044] See Figure 1 , Figure 2 and Figure 10As shown, the dust collection device 6 includes an industrial vacuum cleaner, a flexible hose 61, a rigid tube 62, and a movable dust removal device 63. The rigid tube 62 is fixed to the top of the housing 11, and its lower end extends into the interior of the housing 11 to collect dust particles generated during the operation of the grinding device 3. One end of the flexible hose 61 is connected to the industrial vacuum cleaner, and the other end is connected to the rigid tube 62. The movable dust removal device 63 is installed at the machine cover 31 to clean the grinding belt 39. When the grinding device 3 reaches its upper limit position, the movable dust removal device... 63 connects to the rigid tube 62. After the rigid tube 62 pushes the movable dust removal device 63 down, it contacts the grinding belt 39, keeping the grinding belt 39 rotating slowly. The movable dust removal device 63 cleans the surface of the grinding belt 39, and the cleaned particles are sucked away by the industrial vacuum cleaner. After the dust removal is completed, the machine cover 31 lowers, and the lower end of the rigid tube 62 separates from the movable dust removal device 63. At this time, the suction force generated by the industrial vacuum cleaner acts on the box 11 through the rigid tube 62 to adsorb the particles generated during the grinding and polishing of the workpiece. The industrial vacuum cleaner is connected to the controller 4.

[0045] In the above technical solution, during the grinding process of the grinding device 3, the lower end of the rigid tube 62 is separated from the movable dust removal device 63. At this time, the suction force generated by the lower end of the rigid tube 62 will be concentrated in the box 11 to adsorb the particles generated by the grinding workpiece.

[0046] Every so often, or after grinding multiple workpieces, the equipment enters a self-cleaning mode. In this mode, the motor drives the grinding belt 39 to rotate slowly. Under the drive of the first servo push rod 38, the machine cover 31 moves upward to near the top of the housing 11. At this time, the rigid tube 62 is inserted into the movable dust removal device 63, and the movable dust removal device 63 is driven downward to contact the outer surface of the grinding belt 39, thus sweeping the surface of the grinding belt 39. The particles swept off are absorbed by the movable dust removal device 63 and the rigid tube 62.

[0047] See Figure 10As shown, the movable dust removal device 63 includes a mounting base 631, a base plate 632, a movable tube 633, and a first spring 638. The outer wall of the movable tube 633 is machined with a guide groove 634, which extends downward through the movable tube 633. An insertion hole is provided at the top of the cover 31, and a guide block that matches the guide groove 634 is provided on the hole wall, so that the movable tube 633 can only move along the axial direction of the insertion hole. The mounting base 631 is hollow inside. The lower end of the movable tube 633 is fixedly connected to the mounting base 631 by screws and communicates with the inner cavity of the mounting base 631. An air intake 635 is provided at the bottom of the mounting base 631. The base plate 632 is fixed to the bottom of the mounting base 631. The base plate 632 is frame-shaped so that the air intake 635 is exposed. The base plate 632 is made of rubber and is fixed to the mounting base 631 by gluing. The substrate 632 has bristles 636 embedded on its surface; the bristles 636 are made of metal or nylon, with metal bristles for diamond grinding belts and nylon bristles for abrasive cloth belts. A retaining ring 637 is integrally formed on the body of the movable tube 633. The first spring 638 is sleeved on the movable tube 633 and acts between the retaining ring 637 and the cover 31. Under the rebound action of the first spring 638, the mounting base 631 moves upward so that the bristles 636 disengage from the polishing belt 39. The lower end of the rigid tube 62 is a tapered end 621. An elastic sealing ring (such as a silicone ring) is provided on the inner side of the upper end of the movable tube 633 to ensure the sealing effect after the tapered end is inserted. When the cover 31 moves upward to the limit position, the tapered end 621 is inserted into the upper end of the movable tube 633 and pushes the movable tube 633 downward so that the bristles 636 contact the polishing belt 39.

[0048] In the above technical solution, the first spring 638 rebounds and drives the mounting base 631 to move upward, so that the brush bristles 636 do not come into contact with the grinding belt 39 during the normal grinding process of the grinding belt 39, thus avoiding abnormal wear of the brush bristles 636.

[0049] During the self-cleaning process, the polishing belt 39 rotates slowly, and the bristles 636 sweep and brush the surface of the polishing belt 39 to remove particles attached to the surface of the polishing belt 39 and restore the polishing effect.

[0050] See Figure 2 As shown, the quality inspection device 5 includes multiple cameras with different focal lengths and an alarm. The cameras and alarms are all connected to the controller 4. The cameras are located in the discharge direction of the housing 11 and are used to perform surface quality inspection on the processed workpieces.

[0051] Multiple cameras are used to take pictures in combination, and the pictures are transmitted to the controller 4 in real time. The controller 4 is connected to the network and compares the images with AI software (which needs to be trained and fed qualified and unqualified products) to determine whether the surface quality of the workpiece is qualified. When the quality of the workpiece is unqualified, the controller 4 will issue an alarm.

[0052] The camera contains at least one macro camera.

[0053] By setting the program of controller 4, when the AI ​​identifies that the workpiece is of unqualified quality, controller 4 can drive the conveyor to rotate so that the unqualified workpiece can re-enter the box 11 and receive secondary grinding by grinding device 3.

[0054] In this embodiment, the camera includes a macro high-definition industrial camera, an industrial area array camera, and an auxiliary lighting camera.

[0055] Images captured by a macro camera are used by an AI model to identify micro-scratches with a width ≤0.05mm and a length ≤1mm, as well as pinholes with a diameter ≤0.1mm. Images captured by industrial area array cameras are used by AI models to identify macroscopic defects such as uneven polishing texture areas exceeding 5% and edge burr height exceeding 0.2mm.
