本発明はカラーブラウン管用のシャドウマスク構体の製
造装置に関し、特にシャドウマスクを支持フレームの内
側に溶接する機構に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for manufacturing a shadow mask structure for a color cathode ray tube, and more particularly to a mechanism for welding a shadow mask to the inside of a support frame.

６２−１７８１９号公報にＤｆＴ示されている。Conventionally, this type of mask manufacturing equipment is as shown in Fig. 2(a).
, As shown in (b), the shadow mask 1 and the frame 2 are fitted, and the distance between the frames 2-h21. ' is placed in the raised position, and the frame support 21' is lowered along the guide rod 32', so that the mask 1 is positioned by the mold 41, and the frame 2 is further lowered and positioned by the pin unit 33, and welding is performed. gun 42
A device for welding the mask 1 and the frame 2 by DfT is disclosed in Japanese Patent Publication No. 17819/1983.

リアランスがあり、相互に自由に動くことを前提として
いる。すなわち、第３図（ａ）に示すように、マスク１
の開口寸法ＬＨとフレーム２の開口寸法ＬＦの関係は、
ＬＭ＜ＬＦとなっている。The conventional welding apparatus described above is based on the premise that there is a clearance between the mask 1 and the frame 2, and that they can freely move relative to each other. That is, as shown in FIG. 3(a), the mask 1
The relationship between the opening dimension LH of the frame 2 and the opening dimension LF of the frame 2 is as follows.
LM<LF.

間にクリアランスがないことから、従来の溶接機では位
置決めができないという欠点がある。However, when the frame 2 is welded to the mask with the relationship LM<Lr, sagging is likely to occur on the mask curved surface 1a, causing deterioration of the screen quality of the cathode ray tube. Therefore, as shown in FIG. 3(b), the mask 1
When used alone, the shape is such that the opening dimension +-M'>+- as shown by the solid line, and when it is inserted into the frame 2, a force F is applied to the skirt portion 1b to form the shape shown by the dotted line to create tension Fa on the mask curved surface 1a. A method is used to prevent sagging by letting the In this case, it is difficult to fit the mask 1 and the frame 2 together manually, and since there is no clearance between the mask 1 and the frame 2, there is a drawback that positioning cannot be performed using a conventional welding machine.

やはり位置調整が困難という欠点を有する。Furthermore, as a method of fitting mask frames having the dimensional relationship as shown in FIG. However, when welding, it returns to its shape at room temperature, so
It also has the disadvantage that position adjustment is difficult.
