The first pole piece 62 and/or the second pole piece 63 may be handled by handling to the surface of the membrane 61 to form the lamination unit 6, at which time the transfer assembly 2 transfers the membrane 61 to the handling station 7, and then the pole piece transfer mechanism in the transfer assembly 2 handles the pole piece to the surface of the membrane at the handling station 7 to form the lamination unit 6. Alternatively, the first and/or

second pole pieces

62, 63 may be bonded to the surface of the membrane 61 by thermal compound bonding to form the lamination unit 6, and the transfer assembly 2 transfers the membrane and the pole pieces bonded thereto to the handling station 7.

A carrying assembly 4 may be disposed on one side of the lamination table 1, the carrying assembly 4 carries the lamination unit 6 located on the carrying station 7 to a mounting surface 10 on the lamination table 1 to form a stacking unit 8, the stacking unit 8 is disposed with at least a pole piece, a diaphragm and a pole piece in sequence along a vertical direction of the mounting surface 10, it should be noted that the pole pieces on two sides of the diaphragm in the stacking unit 8 may be pole pieces with different polarities. After the conveying assembly 4 repeatedly conveys the lamination units 6 of the set number of groups onto the lamination table 1, the cells are formed on the lamination table 1.

The side of the stacking unit 8 opposite to the stacking table 1 is provided with a pressing plate assembly 5, the pressing plate assembly 5 comprises a driving member 51 and a pressing plate 52, a moving end of the driving member 51 is connected with the pressing plate 52, the pressing plate 52 at least presses an area of the central axis of the stacking unit 8 far away from the pressing knife assembly 3, so that the first folding area 81 of the stacking unit 8 far away from the pressing knife assembly 3 is flattened, and the pressed stacking unit 8 is relatively static with the mounting surface 10.

As the handling assembly 4 handles the lamination unit 6 to the lamination station 1, the membrane 61 between the handling station 7 and the lamination station 1 is folded around the pressing blade 31 on the pressing blade assembly 3 and on the lower surface of the lamination unit 6, wherein one end of the membrane 61 passes around the lamination unit 6 to form a first folding area 81, the first folding area 81 is far away from the pressing blade assembly 3, and the other end of the membrane 61 passes around the pressing blade 31 on the pressing blade assembly 3 to form a second folding area 82, and the second folding area 82 is close to the pressing blade assembly 3.
