Drum-type blind slot wet film coating device

The invention relates to the technical field of coating devices, and particularly discloses a drum-type blind slot wet film coating device which comprises a base, a top cover is jointly installed at four corners of the upper surface of the base through supporting protrusions, two electric cylinders are connected to the lower surface of the top cover through two lead screw transmission assemblies respectively, and the output ends of the electric cylinders face the base and are provided with suction cups. The upper surface of the base is horizontally provided with a material placing table, a dust sticking roller, a liquid storage tank, an air drying area and a material taking table in sequence; when the smearing roller rotates, the hole entering rods at different positions can be sequentially located on the upper side, so that blind groove positions at different positions on a circuit board can be conveniently coated, and the operation that a worker needs to shift the circuit board for multiple times when coati
