Referring to fig. 7 and further referring to fig. 3, in which fig. 7 is a schematic perspective view of a top grinding unit, it can be seen from the above two views that the top grinding unit includes two second grinding belts 14, and the two second grinding belts 14 are respectively rotatably connected to two side edges of the lifting portion of the supporting arm 15, and the two second grinding belts 14 are respectively opposite to the two first grinding belts 11; the lifting part of the supporting arm 15 is connected with a second grinding motor 16 for driving the second grinding belt 14 to rotate, and the rotation directions of the first grinding belt 11 and the second grinding belt 14 are consistent; similarly, the outer surface of the second sanding belt 14 is also bonded with YS2779 type 60 mesh polishing sand paper 12; the two positioning columns 17 movably penetrate through the left end and the right end of the lifting part and are fixedly connected with the supporting part of the grinding platform; an elastic component (such as a spring 18) is sleeved on each positioning column 17, and two ends of the elastic component are respectively abutted against the lifting part of the supporting arm 15 and the supporting part of the grinding platform; an eccentric wheel 19 is arranged above the pressing part of the supporting arm 15, and the wheel center of the eccentric wheel 19 is connected with a power output shaft of the first driving unit; whenever the large end of the eccentric wheel 19 is opposite to the pressing part of the supporting arm 15, the large end of the eccentric wheel 19 is in clearance fit with the pressing part of the supporting arm 15, and the elastic component is in a natural state; when the small end of the eccentric wheel 19 is opposite to the pressing portion of the supporting arm 15, the small end of the eccentric wheel 19 abuts against the pressing portion of the supporting arm 15 to move downwards, and the elastic component is in a compressed state.

The present embodiment defines at the same time: when the pressing part of the small end pressing support arm 15 of the eccentric wheel 19 reaches the lowest point, referring to fig. 8, a state diagram of the first grinding belt 11 and the second grinding belt 14 after contacting with the cuboid sheet magnetic material 41 is shown, it can be seen from the diagram that the cuboid sheet magnetic material 41 completely moves onto the first grinding belt 11, and the second grinding belt 14 contacts with the top surface of the cuboid sheet magnetic material 41 on the first grinding belt 11.

The overall working mode of the polishing processing assembly is as follows: first, referring to the state diagram of the polishing process assembly shown in fig. 9, it can be seen from the figure that after the batch of cuboid sheet magnetic materials 41 completes the process of the previous process, two rows of cuboid sheet magnetic materials 41 are moved onto the two left conveyor belts 6 and into the two channels 3 of the i-stage limiting groove body 1, the conveyor belts 6 on the left and right sides synchronously rotate along the a1 direction by the power of the first driving unit, and simultaneously, the first grinding motor 13 and the second grinding motor 16 are synchronously started to enable the first polishing belt 11 and the second polishing belt 14 to respectively move along the a1 and the a2 directions. Then, when the cuboid sheet magnetic material 41 completely moves to the upper surface of the first grinding belt 11, the small end of the eccentric wheel 19 is pressed against the supporting arm 15 along the direction b1 to move downwards, and the downwards moving supporting arm 15 enables the second grinding belt 14 to contact with the top surface of the cuboid sheet magnetic material 41 on the first grinding belt 11; at this time, since the first and second grinding belts 11, 14 move in the a1, a2 directions, respectively, the coated abrasive 12 of the first and second grinding belts 11, 14 can thoroughly grind the upper and lower surfaces of the rectangular parallelepiped sheet-shaped magnetic material 41. Finally, referring to fig. 3, when the small end of the eccentric wheel 19 is separated from the supporting arm 15, the supporting arm 15 returns to the original position along the direction b2 under the action of the elastic component, the second polishing belt 14 is separated from contact with the cuboid sheet magnetic material 41, and the cuboid sheet magnetic material 41 continues to move along the direction a1 under the drive of the first polishing belt 11.
