[0050] The working principle and use process of the utility model are as follows: when the device is in use, first, the diffuser plate to be polished is placed on the surface of the clamping plate 10 located on the lower side, and the two first electric push rods 9 are controlled to operate so that the two clamping plates 10 clamp the diffuser plate, and at the same time, the diffuser plate is longitudinally moved between the two sets of edge grinding mechanisms, and the operation of the two sets of edge grinding mechanisms is controlled. The extended end of the second electric push rod 20 extends to drive the edge grinding wheels 15 in the two sets of edge grinding mechanisms to contact the edge of the diffuser plate, and the burrs of the diffuser plate are polished under the rotation of the edge grinding wheels 15.
