Abstract: The present application relates to the technical field of battery and provides a device for press-fitting a battery top cover. The device for press-fitting a battery top cover comprises a press-fitting body. The press-fitting body 1 is arranged on one side of the battery top cover facing away from a battery housing. A pneumatic cleaning assembly is arranged on one side of the press-fitting body facing the battery top cover. The pneumatic cleaning assembly is arranged to allow the chips to move out of the battery housing together with gas along a gap between the battery housing and the battery top cover. In the present application, the pneumatic cleaning assembly is arranged to allow the chips to move out of the battery housing together with gas along the gap between the battery housing and the battery top cover under the action of the gas flow so that to keep the inside of the battery housing clean, avoid short circuit in the battery caused by the chips, and improve the safety performance of the battery.
