When the pre-sealing work is performed, the second lifting driving mechanism 45 enables the pre-sealing support 44 to lift and prop against the bottom of the battery tool, and meanwhile, the first lifting driving mechanism 43 works, so that the pre-sealing pressure head 42 acts on the end socket of the battery to complete pre-sealing. After the pre-sealing work is completed, the conveying chain 22 conveys the tool to the sealing mechanism 3 for secondary sealing.
In this embodiment, the sealing is completed through two sealing actions, and the force applied to the battery is relatively small each time, so that the structural damage to the battery case is reduced, and the rejection rate is reduced.
