WIPO Patent Application WO/2019/135505
Kind Code:
A1
Abstract:
The present invention provides a laser welding apparatus configured to weld at least one electrode lead of a secondary battery of a battery module to a main busbar configured to electrically connect a plurality of secondary batteries to each other. To achieve the above purpose, the laser welding apparatus according to the present invention comprises: a laser beam light-emitting unit including a laser light emitting element to irradiate the electrode lead and the main busbar with a laser beam; a close contact jig including a close contact part horizontally moving to allow the electrode lead to be in close contact with the main busbar; and a blocking block which blocks a laser beam generated by the laser beam light-emitting unit from reaching the secondary battery or is open to allow the generated laser beam to pass therethrough in accordance with a horizontal movement position of the close contact part.
