Abstract

An auto-pressing jig apparatus according to an embodiment of the present invention is a pressing jig apparatus configured to press a busbar, which is provided in a battery module, and a lead assemblyto each other, the auto-pressing jig apparatus comprises a plurality of pressing units which press each of a plurality of busbars provided in the battery module simultaneously, and press an end portion of the lead assembly from an upper portion of the busbars such that the lead assembly does not protrude to a surface of the busbars; a support plate which is connected to an end portion at one sideof the pressing units to support the plurality of pressing units; and a distance adjustment unit which is connected to the support plate to enable the support plate to flow, such that the plurality ofpressing units move away from or close to the battery module.

Description

technical field [0001] The present disclosure relates to an automatic pressing jig apparatus for closely attaching electrode leads to bus bars, and more particularly, to an automatic press jig apparatus for simultaneously closely attaching electrode lead assemblies of a plurality of battery cell stacks to bus bars. Press the clamp. [0002] This application claims priority from Korean Patent Application No. 10-2018-0075762 filed in Korea on June 29, 2018, the disclosure of which is incorporated herein by reference. Background technique [0003] In a conventional battery module, a bus bar is used to electrically connect stacked battery cells to each other, and a plurality of electrode leads respectively drawn from a plurality of battery cells are bent and positioned on the bus bar, followed by welding. [0004] When manufacturing a battery module in this way, in a state where the bent electrode leads are positioned on the bus bars, the electrode leads are closely attached to...
