CN-224205541-U - Battery piece buckling device, battery string carrying equipment and battery piece fixing buckling component

Abstract

The utility model provides a battery piece buckling device, battery string carrying equipment and a battery piece fixing buckling assembly. The battery piece buckling device comprises a pressing structure, a driving structure connected with the pressing structure and used for pushing the pressing structure to press towards the battery piece, and an adsorption structure arranged on at least one side of the pressing structure and used for propping against one surface of the battery piece. Therefore, the battery piece buckling-restrained device can conduct buckling-restrained by the pressing structure at the protruding portion of the welded battery piece, and can alleviate excessive warping of the side portion of the battery piece caused by the fact that the pressing structure presses the battery piece down through the adsorption structure to support against one surface of the battery piece, so that warping of the welded battery piece is reduced.
