The work aims to solve the problems of uneven coating, liquid leakage and low production efficiency caused by poor effect and high labor intensity of manual clamping in electroplating of gravure platemaking. According to the chucking requirement of workpiece, an automatic chucking appliance was designed. The chucking force, deflection and diversion ability of the chucking appliance were verified and calculated, and the chucking appliance was analyzed empirically. The automatic chucking appliance had high clamping strength and could convey uniform current to the surface of the drum, thus obviously improving the uniformity of the coating, reducing the labor intensity, increasing the production efficiency by 42%, and solving the leakage problem. The automatic chucking appliance is superior to manual fixture in plate loading efficiency, coating quality, leakage control and energy consumption and can completely replace manual fixture in production and has a good application prospect.
