film winding device

Abstract

The invention discloses a piece-making and winding joining device which is used for process control of a pole piece between a piece-making system and a winding system of an electric core fully automatic winding machine. The piece-making and winding joining device comprises a vertically arranged substrate of the fully automatic winding machine, a swing deviation correction part arranged on the substrate, a pole piece driving mechanism and a tension control mechanism, wherein the delivery direction of the pole piece is parallel with the substrate; the swing deviation correction part is connected after the piece-making procedure, is internally provided with a snakelike buffer region of the pole piece, and is used for performing swing deviation correction on the pole piece after subjected to the piece-making procedure; and the pole piece driving mechanism and the tension control mechanism are connected sequentially, and are used for drawing the pole piece in the snakelike buffer region and performing tension control on the pole piece which enters into the winding procedure. The piece-making and winding joining device has the advantages that: the swing deviation correction mechanism removes vertical deviation between the pole piece and the vertical substrate efficiently, enables the edge positioning precision of the pole piece to be high and enables the pole piece to enter into the winding part in parallel and precisely; and the tension control mechanism controls the tension of the pole piece, and adopts different tensions for pole pieces with different widths so as to prevent corrugation and breakage of the pole pieces.
