Copper substrate edge polishing device

The utility model relates to a polishing device, in particular to a copper substrate edge polishing device. The copper substrate edge polishing device is high in safety. The copper substrate edge grinding device comprises a supporting frame, a servo motor, a first rotating shaft, a grinding wheel and the like. A servo motor is connected to the rear side of the top of the supporting frame, a fixing frame is connected to the rear side of the servo motor, a first rotating shaft is connected to an output shaft of the servo motor through a coupler, the upper portion of the first rotating shaft is rotationally connected with the fixing frame, and a polishing wheel is connected to the middle of the first rotating shaft. An output shaft of the servo motor drives the first rotating shaft to rotate through the coupler, the first rotating shaft drives the grinding wheel to rotate at the same time, and when the grinding wheel makes contact with the copper substrate, the grinding wheel grinds the copper substrate. 本实用新型涉及
