Composite pole piece preparation mechanism and cell production device

The utility model discloses a composite pole piece preparation mechanism and a battery cell production device, and relates to the technical field of battery cell preparation. The composite pole piecepreparation mechanism comprises a traction driving piece and two composite compression rollers. And the two composite compression rollers are used for receiving the pole piece and the diaphragm and rolling the pole piece and the diaphragm together to form the composite pole piece. And the traction driving piece is used for pulling the composite pole piece along the conveying direction of the polepiece and the diaphragm. According to the composite pole piece preparation mechanism and the battery cell production device, the composite pole piece can be formed by rolling without using a mylar membrane, and the produced composite pole piece is not easy to generate diaphragm separation or diaphragm tearing. 本实用新型公开了一种复合极片制备机构及电芯生产装置，涉及电芯制备技术领域。该复合极片制备机构包括牵引驱动件和两个复合压辊。两个复合压辊用于接收极片和隔膜，并共同辊压极片和隔膜，且形成复合极片。牵引驱动件用于沿极片和隔膜的输送方向
