Preferably, after the lower tape set 8 is attached to the battery sheet 9 from bottom to top, the lower tape set 8 is rolled by a liftable roller 11 to ensure firm attachment. In the process of adhering the bottom of the battery piece 9, a carrying mechanism (a sucker) above the battery piece 9 and a rolling mechanism below the lower adhesive tape group 8 apply pressure in opposite directions (the direction of the battery piece 9) to bear the battery piece 9, after the adhesive tape of the lower adhesive tape group 8 is contacted with the battery piece 9, the fixing of the lower adhesive tape group 8 is loosened, and the firm adhesion of the lower adhesive tape group 8 is realized through reciprocating rolling.
S4: if there are other battery cells 9 in the next battery cell station of the currently operated battery cell 9, all battery cells 9 downstream of the currently operated battery cell 9 are moved downstream by one battery cell station.

Preferably, the supporting plate 21 is lifted to 2-3mm higher than the top surface of the supporting plate 21 on the fixed table 4; the pallet 21 is lowered to 2-3mm below the top surface of the pallet 21 and below the stationary table 4.

Step S4 may be performed simultaneously with steps S1-S3 to increase efficiency.
