[0043] The control system can be set according to the specific use environment, for example, it can be controlled by a single-chip microcomputer or by PLC, ARM (Advanced RISC Machine), FPGA (Field-Programmable Gate Array) and other methods, which are not specifically limited in this embodiment; the moving component is a universal wheel, and the specific number is selected according to actual needs. At the same time, a support component can be set at the bottom to facilitate the fixation of the device.

[0044] When the present invention is working, the overall regulation is carried out through the control system. The control system controls the two-axis machine to drive the clamp to clamp the workpiece to be processed on the workpiece placement rack 2 and move it to the top of the dust removal component. The three-axis machine controls the fine grinding component and the rough grinding component to perform rough grinding and fine grinding on the workpiece to be processed. After the grinding process is completed, the conveying component is used to convey the grinded workpiece to the verification component. The verification component is used to compare and verify whether the grinded workpiece meets the final finished product requirements. If it meets the requirements, the processing is completed and the workpiece is recycled. If it does not meet the requirements, it is polished again.

[0045] The present invention combines the rough grinding component and the fine grinding component into a unified device, thereby improving the grinding efficiency. At the same time, the finished product is checked by a checking mechanism to ensure the quality of the finished product.

The electromagnet 34 absorbs the polished magnet on the clamp 8 and transfers it to the calibration groove 22 on the top surface of the calibration disk 21. The direction of the magnetic field is controlled by controlling the current direction of the electromagnet 34, so that the electromagnet 34 can attract or repel the processed magnet. The calibration groove 22 is made of various specifications to ensure that magnets of various specifications and sizes can be calibrated. The appearance and shape of the magnet are recognized by the recognition camera to confirm whether the magnet grinding meets the use requirements. At the same time, the recognition camera marks multiple verification grooves 22, and the rotation of the entire calibration disk 21 is controlled by the rotating device at the bottom. At the same time, the electromagnet 34 picks up the non-compliant magnets and polishes them again. The magnets that meet the use requirements are transported to the recycling box by the electromagnet 34 to ensure that the polished magnets meet the use requirements.
