Title
(EN) METHOD AND DEVICE FOR WELDING SPRING TO APERTURE GRILLE
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE SOUDER DES RESSORTS SUR UN MASQUE A FENTES
Abstract
(EN)
An aperture grille (1 or 21) is so placed as to face to a prescribed reference plane, and the springs are placed by using three or four spring positioning means. Then the attitude of the aperture grille (1 or 21) is adjusted based on the results of measurement of the grille (107) at measuring points Z0-Z4 and the positions of spring pins which support the springs are made to coincide with those of panel pins provided on a panel. Then the springs are simultaneously welded to the sides of the aperture grille accurately. In addition, even when four springs are welded, the springs can be welded simultaneously by using only one equipment.
(FR)
Un masque à fentes (1 ou 21) est placé de façon à faire face à unplan de référence prescrit, et les ressorts sont mis en place à l'aide de trois ou de quatre moyens de positionnement de ressort. Ensuite la position dudit masque à fentes (1 ou 21) est réglée sur la base des résultats de mesures effectuées sur le masque (107), aux points de mesure Z0-Z4, puis on fait coincider les positions des broches qui supportent les ressorts avec celles de broches placées sur un panneau. Ensuite, on soude simultanément les ressorts, avec précision, sur les côtés du masque à fentes. En outre, il est également possible, même lorsqu'il s'agit de souder quatre ressorts, de souder lesdits ressorts simultanément au moyen d'un seul équipement.
