Abstract

PURPOSE: To keep the space between panel and shadow mask constant by welding two springs at first and then welding the remaining spring when welding three springs onto support frame.
CONSTITUTION: The shadow mask support frame 1 is held at a fixed position by the stopper 6 and the receiver 7, and the holes of the springs 5, 5a, and 5b are fitted on the tap pins 10, 10a, and 10b. Then, the air cylinder 14 is operated to weld the springs 5a and 5b to the frame 1 by electrifying the electrodes 11a and 11b, and then the frame 1 is positioned by the three points of the flat guage 16 and the tap pins 10a and 10b and the spring 5 is welded to the frame 1. Thus, fitting can be made according to the dispersions of each spring, so that the space between the panel and the shadow mask can be kept constant and the quality of Braun tube can therefore be raised.
