Abstract

L'invention concerne une tête de soudage par ultrasons et un dispositif de soudage. La tête de soudage par ultrasons comprend quatre ensembles de soudage en forme de ligne (104). Les quatre ensembles de soudage en forme de ligne (104) sont raccordés de manière fixe les uns aux autres de manière à être perpendiculaires entre eux, de manière à former une tête de soudage en forme de plus (1). La section transversale de la tête de soudage en forme de plus (1) est une structure en forme de plus symétrique par rapport au centre. Le dispositif de soudage comprend la tête de soudage. Lorsque des ressorts ensachés (4) sont soudés au moyen de la tête de soudage en forme de plus, un bord de soudage rectangulaire peut être soudé par le soudage des sachets seulement deux fois, tandis qu'un bord de soudage rectangulaire peut être soudé au moins trois fois au moyen d'une tête de soudage en forme de L formée par des têtes de soudage en forme de ligne linéaires. Les têtes de soudage peuvent utiliser un transducteur, et de multiples transducteurs de soudage n'ont pas besoin d'être utilisés sur un même point de soudage, ce qui permet de réduire l'espace occupé par le dispositif de soudage.
