Coating device and battery processing equipment

The utility model relates to a coating device and battery processing equipment. The coating device comprises a base; the coating assembly is movably arranged on the base, and the coating assembly is used for coating an insulating coating on a pole piece and is configured to be capable of forming the insulating coating extending in at least two different directions on the pole piece. The pole pieces are coated with the insulating coatings through the coating assembly, the insulating coatings can cover the positions, with burrs, of the pole pieces, and in the stacking process of the pole pieces, the insulating coatings can reduce the probability that the adjacent pole pieces are pierced by the burrs and lithium precipitation occurs; the insulating coating formed on the pole piece by the coating assembly can extend along at least two different directions, so that burrs on the pole piece can be more comprehensively covered by the insulating coating, and the problems of lithium precipitation, burr puncture and the like can be more effectively solved.
