▎ 摘　　要

NOVELTY - The device has a supporting plate (13) whose top portion is provided with a metal plate (14). An output end of a stepping motor is connected with a driving gear (21) through a speed reducer. The driving gear is connected with a top portion of a movable plate. A right outer wall of an outer frame (1) is connected with a fixing frame (22). A left side of a top portion of the fixing frame is provided with a servo motor (23). An output end of the servo motor is connected with a screw rod (26) through the speed reducer. An outer wall of the screw rod is provided with a coating device (27). A top portion of the fixing frame is formed with a material collecting groove (28). A top portion of a top plate(4) is provided with a baffle rod (29). A top portion of the fixing frame is provided with a fixing plate(25). An outer wall of the fixing plate is connected with a locating plate (24). USE - Processing device for coating graphene on surface of a metal plate. ADVANTAGE - The device can drive the metal plate up and down in a containing box in convenient manner, so that graphene dye can be easily coated on a surface of the metal plate, the graphene dye is coated on the surface of the metal plate, and redundant dye on the graphene surface is removed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a processing method for coating graphene on surface of a metal plate. DESCRIPTION OF DRAWING(S) - The drawing shows a side view of a processing device for coating graphene on surface of a metal plate.
