摘要： Provided are a centrifugal battery liquid injection mechanism and a liquid injection method thereof. The centrifugal battery liquid injection mechanism comprises a liquid injection device and a driving device, the liquid injection device is provided with a piston mechanism and a liquid outlet head capable of being opened and closed, and one end of the liquid injection device close to the liquid outlet head is further provided with a liquid injection port capable of being opened and closed; and the liquid injection port is used for injecting a wetting liquid into the liquid injection device. The liquid injection device is connected with a to-be-wetted device through the liquid outlet head, so as to inject the wetting liquid into the to-be-wetted device. The driving device is connected with the to-be-wetted device for driving the to-be-wetted device to move.

摘要： Disclosed are a method and device for welding and converging battery cell tabs, which is used for welding and converging battery core end faces. The method comprises: laminating to form a plate set composed of a positive plate, a separator and a negative plate by laminating, the positive plate comprising a positive tab, and the negative plate comprising a negative tab; during laminating, bending the positive tab to form a positive tab bend, and bending the negative tab to form a negative tab bend; and welding the positive tab bend of each positive plate in the plate set, and/or welding the negative tab bend of each negative plate in the plate set. Based on the method and device, a reserved length of the tab is reduced, and a material loss of the tab material is greatly reduced. Station circulation is reduced and production efficiency and a product yield are improved.
