NOVELTY - The utility model claims a metal foil surface coated graphene device, comprising a control unit and set in turn along the movement direction of the metal foil unreeling unit, coating printing device, a baking unit and a winding unit. the metal foil is an aluminium foil or a copper foil, coating printing device comprises a pressing roller set and overlapped; the active silica gel roller and the driving steel roller, the active silica gel roller and the driving steel roller to rotate in opposite direction and maintaining the gap of micron grade; the driving steel roller immersed in the glue pool of viscous material; base material set between the pressing roller and the active silica gel roller. The utility model is realized in a sub-micron thickness and thin layer of material on the surface of the substrate uniformly coated, which adapts to the graphene coating thickness requirement on the metal foil, and has good adhesive force, effectively reduces the contact resistance between the carbon particle and the metal foil.
