本発−はブラウン管のファンネルシール面にフリットガ
ラスをＩｋ布する装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for applying frit glass to the funnel sealing surface of a cathode ray tube.
従来、ブラウン管のフリットガラスの塗布装置は、第１

。Conventionally, the frit glass coating device for cathode ray tubes has a first
It consists of a structure as shown in 1I. That is, the funnel 1 is held by the holder 2 and further rotated by the external motor 3 through the pulley 4.5. This rotation is controlled using, for example, a position detection switch 6 so that the frit glass coating is easily and accurately performed in one rotation.

Add a fritted glass to the sealing surface of the stirring blade 9.
is stirred by an external motor 10 through gears 11 and 12, high-pressure air 13 is applied from the outside, and the needle 14 is moved up and down by an air cylinder 15 to close the nozzle portion 16. It has become.

リットガラスの塗布量が得られるようになっている。The frit dispenser 7 also has a guide roller 17 for guiding the inner side of the funnel seal 1, a guide shaft 18 for guiding the dispenser 7 in parallel, and a slide bearing 19. It is designed to be able to accurately follow changes in . Furthermore, by knowing the position of the sealing surface, the speed of the motor 3 is controlled, so that a uniform amount of frit glass can be applied over the entire circumference.

要となるという欠点があった。However, in such a conventional device, as shown in FIG. is formulated in such a way that it dries extremely quickly and loses its fluidity, so when you try to start the next application, as shown in msm,
The overlapping portion 20 of the start and end of frit glass application is woven and protrudes outside the seal 1jla and hangs, so this is corrected by scraping off the overlapping portion 20 with a spatula or the like by hand or another automatic machine. The disadvantage is that it requires more work.
本発明の目的は７リツトガラス塗布後の修正を必要とし
ないフリットガラスの塗布装置を提供することにある。An object of the present invention is to provide a frit glass coating apparatus that does not require modification after coating the frit glass.
以下、本発明の一実施例を第４Ｆ！！Ｊにより説明する

Note that the same or equivalent members as in FIG. 1 are designated by the same reference numerals, and their explanations will be omitted. The tip 14a of the needle 14 is made to match the inner shape of the nozzle 16. As a result, the frit glass in the nozzle hole is completely pushed out by the tip portion 14a every time the coating is completed, and it is possible to prevent the frit glass from sagging due to the swelling of the coating weight portion. In addition, even if a rise occurs, the portion 2 shown in Figure 3
By blowing voltage air 22 from a high-pressure air nozzle 21 onto the sheet, the binder on both sides is blown away, fluidity is eliminated, and sagging can be prevented.
本発明によれば、フリットガラスの塗布重なり部の垂れ

ある。According to the present invention, since it is possible to prevent the frit glass from sagging at the overlapped portion of the coating, it is possible to omit the work of correcting the overlapped portion after coating, which was conventionally necessary. Another advantage is that it is now possible to easily fully automate the frit glass coating process, which has been difficult in the past due to the hindrance of correction work.
