[0024] A motor 11 is installed on one side of the casing 1. A gear 15 is installed on the main shaft of the motor 11. The gear 15 is responsible for transmitting the power of the motor 11 to the movable box 12 inside the casing 1. Fan blades 18 are installed on the rotating shaft 6 of the motor 11. These fan blades 18 work in conjunction with exhaust vents 10 and 17 to help dissipate heat from the device. A rack 16 is installed on one side of the gear 15. The gear 15 and the rack 16 are connected by gear teeth meshing. The rack 16 is fixed to one side of the movable box 12. An exhaust vent 17 is installed on each side of the movable box 12. The function of exhaust vents 10 and 17 is to exhaust the hot air inside the casing 1, ensuring that the inside of the casing 1 maintains a suitable temperature and air quality. A protrusion is provided on one side of the movable box 12. A slide rail 14 is installed on the inner wall of the casing 1. The protrusion on the movable box 12 is slidably connected to the slide rail 14, allowing the movable box 12 to move up and down inside the casing 1.

[0025] A second motor 13 is installed on the bottom end face of the moving box 12. The main shaft of the second motor 13 is sleeved with the rotating shaft 6. A vacuum pump 7 is installed on the rotating shaft 6. The main function of the vacuum pump 7 is to extract air from the cylinder 8. Together with the suction cup 9, it can stably grip the workpiece to be polished. One side of the vacuum pump 7 is sleeved with the cylinder 8. The top of the cylinder 8 is connected to the suction cup 9. A position sensor 19 is installed on one side of the cylinder 8. This sensor is used to monitor the position of the suction cup 9 in real time to ensure that the suction cup 9 can accurately grip and place the workpiece. A detector 20 is installed on the polishing device 23. This detector 20 is used to detect the quality of the workpiece after polishing to ensure that the polishing effect meets the expected standard. The position sensor 19, the detector 20 and the control system are electrically connected.

[0026] The working principle of this utility model is as follows: Before operation, the automatic loading and unloading device first adds the workpiece to be polished into the feeding bin 4. The control system motor 13 starts running, and the main shaft of motor 13 drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the cylinder 8 to rotate. The position sensor 19 transmits the position of the suction cup 9 to the control system in real time. The control system causes the suction cup 9 to rotate above the feeding bin 4. Motor 11 starts running, and the main shaft of motor 11 drives the gear 15 to rotate clockwise. The gear 15 meshes with the rack 16, causing the moving box 12 to move downward along the slide rail 14. The moving box 12 drives the rotating shaft 6 to move downward, allowing the suction cup 9 to enter the feeding bin 4 and contact the workpiece. At this time, the vacuum pump 7 starts. Vacuum pump 7 extracts air from cylinder 8. Under negative pressure, the workpiece to be polished is tightly attracted by suction cup 9. Then, motor 11 rotates in reverse, driving gear 15 to rotate in reverse. Gear 15 meshes with rack 16, causing moving box 12 to move upward along slide rail 14, so that suction cup 9 moves upward away from feed bin 4. Then motor 13 is started in reverse. The main shaft of motor 13 drives rotating shaft 6 to rotate. Rotating shaft 6 drives cylinder 8 to rotate, so that suction cup 9 rotates between polishing device 2 and polishing device 3. Vacuum pump 7 runs, and cylinder 8 is refilled with air, so that the workpiece falls onto polishing device 2. Then motor 13 is started again, so that suction cup 9 moves away from below polishing device 3.

[0027] The polishing device polishes and grinds the workpiece. After polishing, the detector 20 checks the processed workpiece. If the processed workpiece meets the requirements, the control system controls the second motor 13 to operate. The main shaft of the second motor 13 drives the rotating shaft 6 to rotate, which in turn drives the cylinder 8 to rotate, causing the suction cup 9 to return to above the workpiece. The vacuum pump 7 starts, extracting air from the cylinder 8. Under the negative pressure, the workpiece to be polished is tightly attracted by the suction cup 9. The second motor 13 rotates, causing the suction cup 9 to move above the discharge bin 5. The first motor 11 rotates clockwise, causing the suction cup 9 to move downward into the discharge bin 5. The vacuum pump 7 operates, refilling the cylinder 8 with air, causing the workpiece to fall into the discharge bin 5. If the processed workpiece does not meet the requirements, the thicker workpiece is repolished and the thinner workpiece is moved to the waste bin via the suction cup 9 and the rotating shaft 6.

[0028] Throughout the process, motor 11 operates, and the blades 18 on the rotating shaft of motor 11 rotate. The rotating blades 18 agitate the air inside the housing 1, which, together with exhaust windows 10 and 17, cools motor 2 13, enabling the entire loading and unloading device to operate continuously and improving production efficiency.
