Before the Pack wire extrusion stacking process, the surface of the battery cell and the surface of the battery cell need to be subjected to foam mounting after the pole cleaning process, so that the two battery cells are firmly adhered, and the preparation of the extrusion stacking of 8 battery cells in the later working section is performed. But in order to ensure the pasting effect of the foam, the foam with the sub foam distributed at intervals is provided for pasting, so that the pasting effect can be ensured while the foam is saved. However, in practical application, because the area of the bonding surface of the battery cell is uncertain, only the bottom film of the foam can be torn off in the traditional bonding assembly and then bonded to the surface of the battery cell at original intervals, at this time, due to the difference of the surface areas of the battery cells, the bonding position of the foam is too concentrated in the middle of the surface of the battery cell under partial scenes, so that the effect of subsequent extrusion stacking is poor, the production yield is reduced, and therefore, the bonding assembly is required to adapt to the bonding requirements of different scenes, and the production yield is improved.
