AI Technical Summary
Existing battery tab welding equipment requires frequent fixture changes when dealing with battery casings of different thicknesses and widths or tabs of different specifications. Furthermore, the tabs are easily displaced by external forces or heat, affecting welding quality, battery performance, and safety.
A clamping device comprising a base, a fixing component, and a limiting component was designed. The battery and the tab are adjustablely fixed through a sliding connection and a spring structure to ensure that no displacement occurs during the welding process.
It achieves stable fixation of batteries of different specifications and accurate positioning of the tabs, improving welding quality and battery safety, and reducing welding deviation.
