(EN) WELDING GUN ASSEMBLY AND SYSTEM FOR CONTROLLING SAME, SONOTRODE FOR WELDING GUN
(FR) ENSEMBLE D'UN PISTOLET DE SOUDURE ET DE SON SYSTEME DE CONTROLE, SONOTRODE POUR PISTOLET DE SOUDURE
Abrégé
(EN)
The invention concerns a welding gun assembly (10) and a system for controlling same (12), the gun being designed for ultrasonic welding of an element on a thermoplastic component, consuming a certain amount of power, and comprising a handle (14), a sonotrode (16), a trigger (18) for actuating the sonotrode, the assembly further comprising means (22) for automatically stopping the sonotrode. The assembly is characterized in that it comprises means (24) for detecting excess of a threshold value due to variation of an increase in the power consumed, and in that the automatic stopping means are connected to the detection means, so as to be triggered when said detection is positive.
(FR)
L'invention concerne un ensemble d'un pistolet de soudure (10) et de son système de contrôle (12), le pistolet étant destiné à souder par ultrasons un élément sur une pièce en matière thermoplastique, consommant une certaine puissance, et comportant une poignée (14), une sonotrode (16), une gâchette (18) d'actionnement de la sonotrode, l'ensemble comportant également des moyens (22) d'arrêt automatique de la sonotrode. L'ensemble comprend des moyens (24) de détection du franchissement d'une valeur seuil par la variation de l'augmentation de puissance consommée, et en ce que les moyens d'arrêt automatique sont reliés aux moyens de détection, de manière à être déclenchés lorsque cette détection est positive.
