LASER WELDING APPARATUS FOR ELECTRODE TERMINAL

Document Type and Number:

WIPO Patent Application WO/2014/204030

Kind Code:

A1

Abstract:

Provided is a laser welding apparatus for an electrode terminal for welding plate shaped electrode terminals of a battery cell or a battery module to each other or welding the plate shaped electrode terminals to an external circuit, and more specifically, a pair of pressure rollers formed at a lower side of a laser welding head and vertically movable are used to be moved in a state in which two electrodes are closely adhered, thereby performing continuous laser welding, such that laser welding is performed in a state that electrodes are closely adhered to thereby decrease the welding defect of the electrode terminal.
