Battery cover plate rolling device and rolling method

Abstract

The present application relates to a battery cover plate rolling device and a rolling method, the rolling device comprising a plurality of rolling wheels arranged in sequence from front to back with parallel axes, the plurality of rolling wheels being used to roll the first surface of the upper limiting part in sequence so that the upper limiting part is gradually rolled to abut against the upper insulating part, and after being rolled by each rolling wheel once, the upper limiting part is bent downward by a certain angle relative to the pole column. The present application is simple to use, reduces the assembly difficulty of the battery cover plate, improves the assembly efficiency, and after being rolled by each rolling wheel once, the upper limiting part is bent downward by a certain angle relative to the pole column, so that the upper limiting part gradually deforms, which can effectively prevent the upper limiting part and the connection between the upper limiting part and the pole column from being broken and damaged, the plurality of rolling wheels roll the first surface of the upper limiting part in sequence, which not only makes the battery cover plate assembly fixed firmly, but also ensures the product quality of the battery cover plate.
