る。 Next, a sealing process using the sealing jig 20 will be explained. When the funnel 2 coated with the fritted glass 3 is set in the sealing jig 20, the funnel alignment support members 12a, 12b,
12c, the yoke support member 13 and the neck support member 14 allow the funnel 2 to
It is held at a 20 degree angle. Furthermore panel 1
When set on top of the funnel 2, it is held at the same angle as the funnel 2 by the three panel alignment support members 11a, 11b, and 11c. Next, this is put into a heat treatment section, and the frit glass 3 is crystallized under preset sealing conditions (for example, 440° C.), and the panel 1 and the funnel 2 are aligned and sealed.
In addition, since panel 1 and funnel 2 are inclined toward the alignment side at an angle of 3 to 20 degrees with respect to the horizontal plane, a pressing force is constantly exerted on panel 1 and funnel 2 themselves in the alignment direction during the sealing process. ing. For this reason, the fritted glass 3
This prevents misalignment of the panels and funnels due to melting and vibration, resulting in highly accurate sealing.

The need has arisen. However, when a panel/funnel is lifted with a balancer or the like, it is generally held horizontally, so when setting the funnel 2 on the sealing jig or setting the panel 1 on the funnel 2, it is necessary to There has been a problem in that imbalance occurs in the horizontal plane and defects such as scratches and chips are likely to occur in the panel funnel and frit glass 3.
