The invention relates to a battery film stripping mechanism. The battery film stripping mechanism comprises a film stripping bracket, an upper clamping piece, a lower clamping piece, a battery pushing-in piece and a battery pushing-out piece; the film stripping bracket is vertically arranged on one side of a battery outer film stripping and conveying line; the upper clamping piece, the lower clamping piece and the battery pushing-out piece are arranged on the film stripping bracket; the battery pushing-in piece is arranged on one side of the battery outer film stripping and conveying line andis opposite to the lower clamping piece; the upper clamping piece can move relative to the lower clamping piece to push the battery pushing-in piece to the lower clamping piece so as to clamp a battery on the lower clamping piece; the battery pushing-out piece is opposite to the lower clamping piece; and the battery pushing-out piece is used for pushing out the battery clamped between the upper clamping piece and the lower clamping piece. According to the battery film stripping mechanism disclosed by the invention, the mechanical operation of film stripping is realized, a film stripping success rate is ensured, manual participation is reduced, and working efficiency is improved.
