The utility model relates to a rubberizing mechanism, and belongs to the technical field of battery manufacturing, the rubberizing mechanism comprises a side edge attaching
assembly, the side edge attaching
assembly comprises a mounting seat, and an upper cross arm and a lower cross arm arranged on the mounting seat; the plane attaching
assembly comprises an ejector block arranged between the upper cross arm and the lower cross arm, and an air blowing hole is formed in the side, away from the mounting base, of the ejector block. Therefore, in the process that the
battery cell is pushed into the upper cross arm and the lower cross arm, the end part of the
battery cell is firstly contacted with the
adhesive tape and then is contacted and extruded with the top block, so that the
adhesive tape can be flatly and tightly attached to the end surface of the
battery cell, in addition, a blowing hole is formed in one side, deviating from the mounting seat, of the top block, and gas led out from the blowing hole can provide an acting force; the
adhesive tape is blown to the side where the battery
cell is located, so that the adhesive tape is pre-attached to the end face of the battery
cell, slipping when the two ends of the adhesive tape are pulled is avoided, the risk that the adhesive tape is wrinkled is reduced, the adhesive tape is not prone to deviating from the preset pasting position, the adhesive pasting effect of the end of the battery
cell is further improved, and the flatness and tightness of the adhesive tape pasted to the battery cell are guaranteed.
