In order to solve the problem that the existing edge grinding machine needs to be manually or externally driven to push the PCB board into the edge grinding machine when in use, and because the driving member and the edge grinding machine are split structures, the driving member needs to be aligned with the edge grinding machine and fixed with bolts before each edge grinding, which is very cumbersome, the device includes a slip mechanism, an operating table and a grinding box. The upper outer surface of the operating table is provided with a grinding box, and the front outer surface of the grinding box is provided with an operating hole. The utility model can drive the transmission of the motor to drive the PCB board to the edge grinding machine by the slip mechanism.
