The invention discloses a U-shaped automatic piece wrapping
machine for pole pieces of storage batteries, comprising a piece wrapping mechanism for wrapping a first
pole piece, an
assembly mechanism connected with the
discharge end of the piece wrapping mechanism, a first piece supply mechanism for supplying the first
pole piece to the piece wrapping mechanism and a second piece supply mechanism for supplying the second
pole piece to the
assembly mechanism, wherein the second pole piece and the wrapped first pole piece are piled up at intervals in the
assembly mechanism to form a pole group. The
machine realizes automatic feeding and automatic wrapping of the pole pieces and automatic assembly of the wrapped pole pieces, completes the whole operation process in a streamline manner in one step and improves the wrapping efficiency and quality of the pole pieces. Improvement of the degree of
automation is conductive to correspondingly reducing the probability of manually contacting the pole pieces, thus greatly reducing the harm of lead dust to the operators.
