Title (EN) LASER WELDING JIG AND LASER WELDING DEVICE COMPRISING SAME
(FR) GABARIT DE SOUDAGE AU LASER ET DISPOSITIF DE SOUDAGE AU LASER LE COMPRENANT
(KO) 레이저 용접 지그 및 이를 포함하는 레이저 용접 장치
Abstract:
(EN) A laser welding jig according to one embodiment of the present invention comprises: a jig main body for covering a busbar unit during welding; a plurality of welding slits formed on the jig main body, and exposing electrode leads of battery cells and at least one lead busbar to the outside of the jig main body for the welding; a plurality of blot insertion parts provided between the plurality of welding slits and having at least one bolt insertion hole into which at least one pressing bolt is inserted; and one pair of lead adhering blocks provided on the rear surface of each bolt insertion part, and spaced apart from each other according to the insertion of the pressing bolt so as to adhere electrode leads to each lead busbar.
(FR) L'invention concerne un gabarit de soudage au laser comprenant, selon un mode de réalisation : un corps principal de gabarit pour recouvrir une unité de barre omnibus pendant le soudage ; une pluralité de fentes de soudage formées sur le corps principal de gabarit et exposant des conducteurs d'électrode de cellules de batterie et au moins une barre omnibus de conducteur à l'extérieur du corps principal de gabarit pour le soudage ; une pluralité de parties d'insertion de boulon disposées entre la pluralité de fentes de soudage et ayant au moins un trou d'insertion de boulon dans lequel au moins un boulon de pression est inséré ; et une paire de blocs d'adhérence de conducteur disposés sur la surface arrière de chaque partie d'insertion de boulon et espacés l'un de l'autre en fonction de l'insertion du boulon de pression de façon à faire adhérer les conducteurs d'électrode à chaque barre omnibus de conducteur.
(KO) 본 발명의 일 실시예에 따른 레이저 용접 지그는, 용접 시 버스바 유닛을 커버하는 지그 본체, 지그 본체에 형성되며 용접을 위해 배터리 셀들의 전극 리드들과 적어도 하나의 리드 버스바를 지그 본체 밖으로 노출시키는 복수 개의 용접 슬릿들, 복수 개의 용접 슬릿들 사이 사이에 구비되며, 적어도 하나의 가압 볼트가 삽입되는 적어도 하나의 볼트 삽입홀이 마련되는 복수 개의 볼트 삽입부들 및 각각의 볼트 삽입부의 후면에 마련되며, 가압 볼트 삽입에 따라 상호 이격되어 전극 리드들을 리드 버스바에 밀착시키는 한 쌍의 리드 밀착 블록들을 포함하는 것을 특징으로 한다.
