本発明はブラウン管の製造方法、特に内装黒鉛の塗布に
好適な塗布装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a cathode ray tube, and particularly to a coating device suitable for coating internal graphite.

。As shown in Fig. 1, an internal graphite 2
It is essential to establish electrical continuity between the cavity node 3 and the high-voltage grid of the electron gun 4 by applying .

難、となるという欠点があった。Conventionally, in order to apply the internal graphite 2, as shown in FIG. was applied. However, preventing graphite from adhering to the inner wall of the neck tube 5 is an extremely difficult task, especially when the diameter of the neck tube becomes small, and it is also difficult to obtain a uniform film due to variations among workers. There were drawbacks.
本発明の目的は、内装黒鉛の塗布に熟練を要せず、しか
も均一な品質の塗布膜を有する塗布方法を提供すること
にある。An object of the present invention is to provide a coating method that does not require skill in coating internal graphite and provides a coating film of uniform quality.

換えられて内面の塗布を完了する。An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. In FIG. 3, a cathode ray tube 1 is supported by a receiver 10 and immersed in graphite liquid 12 in a bath 11. Graphite [11
2 is prevented from settling by stirring blades 13. Furthermore, a pipe 14 of an appropriate length is erected in the tank 11 and communicates with the inside of the cathode ray tube 1. Further, the graphite is sucked into the pipe 14), and after reaching a suitable height, the three-way solenoid valve 16 is switched to switch to the atmosphere side pipe 19, and the coating on the inner surface is completed.

た自動化を容易に導入できるという効果がある。The neck tube 5 of the cathode ray tube, which has been coated with graphite inside through the above series of operations, is wiped with a 20# wiper as shown in FIG.
The graphite inside the neck tube 5 can be washed away by continuously supplying water to the neck tube 51 from the pipe 22, and the desired internal graphite film can be easily obtained. The effect is that it can be easily introduced.
本発明によれば、筆などを用いないで塗布できるので、
正確な寸法、均一な塗布膜を熟練を要せずに得ることが
でき、また自動化も容易となる。According to the present invention, it is possible to apply without using a brush or the like.
A uniform coating film with accurate dimensions can be obtained without requiring any skill, and automation is also easy.
