Tab material preparation structure

Abstract

The utility model discloses a tab material preparation structure and belongs to the technical field of soft package batteries. The tab preparation structure comprises a limiting frame, an adsorption piece and an elastic scraping piece; an accommodating space is formed in the limiting frame, the accommodating space is used for limiting and placing a plurality of stacked tabs, one end of the accommodating space along the stacking direction of the tabs is provided with an open end, and the stacking direction of the tabs is parallel to the Z axis; the adsorption part is arranged on one side of the limiting frame and used for stretching into the containing space through the open end and adsorbing the tabs facing the open end to move to a welding station. The elastic scraping piece is connected to the limiting frame and located at the open end of the containing space. The elastic scraping piece is configured to abut against the edge of the electrode lug and generate elastic deformation when the electrode lug passes through the elastic scraping piece. The tab preparation structure can ensure that a single tab taken out is welded with a core body during subsequent welding, so that the whole soft package battery is prevented from being scrapped, and the yield of the soft package battery is improved.
