NOVELTY - The utility model claims a graphene coating device, comprising a substrate unreeling machine, a corona machine and a slit coating machine the discharging end of the substrate unreeling machine is connected with the feeding end of the corona machine, the discharging end of the corona machine is connected with the feeding end of the slit coating machine. The beneficial effects are as follows: the base material unreeling by the base material unreeling machine passes through the corona machine, so that the substrate surface is rough to improve the adhesion of the graphene slurry, then enters the slit coating machine using the slit coating machine the graphene slurry and coating on the substrate, so as to ensure the uniformity of the graphene slurry coated on the substrate can reach the same.
