(EN) ULTRASONIC WELDING SYSTEMS AND METHODS OF USING THE SAME
(FR) SYSTÈMES DE SOUDAGE PAR ULTRASONS ET LEURS PROCÉDÉS D'UTILISATION
Abstract
(EN)
An ultrasonic welding system is provided. The ultrasonic welding system includes a support structure for supporting a workpiece. The ultrasonic welding system also includes a weld head assembly including an ultrasonic converter carrying a sonotrode. The ultrasonic welding system also includes a z-axis motion system carrying the weld head assembly. The z-axis motion system includes (i) a z-axis forcer for moving the weld head assembly along a z-axis of the ultrasonic welding system, and (ii) a z-axis overtravel mechanism disposed between the z-axis forcer and the weld head assembly.

La présente invention porte sur un système de soudage par ultrasons. Le système de soudage par ultrasons comprend une structure de support destinée à supporter une pièce à usiner. Le système de soudage par ultrasons comprend également un ensemble tête de soudage comprenant un convertisseur à ultrasons portant une sonotrode. Le système de soudage par ultrasons comprend également un système de mouvement d'axe z portant l'ensemble tête de soudage. Le système de mouvement d'axe z comprend (i) un piston plein d'axe z pour déplacer l'ensemble tête de soudage le long d'un axe z du système de soudage par ultrasons, et (ii) un mécanisme de surcourse d'axe z disposé entre le piston plein d'axe z et l'ensemble tête de soudage.
