[0003] In the existing collector plate alignment structure, the front and rear sides of one edge of the collector plate are clamped and fixed by a clamping claw bracket, and then aligned with a lifting and translating linear module. This method of clamping the edge of the collector plate makes it difficult to accurately control the concentricity of the cover plate and the battery cell, which makes it easy to cause secondary damage to the cover plate during the subsequent process of inserting the battery cell into the shell.
