洗浄する必要がある。(Prior art) When manufacturing cathode ray tubes, such as color cathode ray tubes,
On the inner surface of the panel that forms the valve together with the funnel,
After forming a phosphor screen consisting of black light-absorbing stripes, three-color phosphor stripes of red, green, and blue, and a film layer formed on top of these to obtain a smooth surface, this panel and funnel are assembled. Before sealing (airtight integration), it is necessary to clean the black Aquadag and the three colors of red, green, and blue phosphors attached to the sealing surface of the panel to be sealed to the funnel. .
そのため、従来は、第3図に示すように、薬液や純水等

A cleaning conveyor 3 with
The lower part of the roller 2 is immersed in the cleaning liquid in the cleaning liquid tank 1, and the sealed surface of the panel P is supported by the roller 2 of the cleaning conveyor 3, and the panel P is conveyed by the rotation of the roller 2. The sealed surface of the panel P was cleaned by bringing the roller 2 coated with cleaning liquid into contact with the sealed surface of the panel P.
(発明が解決しようとする問題点)
上述した従来の装置の場合、パネルPのシール面に洗浄
液が付着したローラ2を単純に接触させるだけなので、
洗浄効果が低く、パネルPのシール面に汚れが残ること
があり、後の工程で、パネルPとファンネルを封着し、
パネルPとファンネルから成るバルブのネック部に電子
銃を封止し、バルブ内の排気を行なった際に、パネルP
のシール面の汚れが原因で封着が不十分となっていたバ
ルブが爆縮するという不良が発生することがあった。(Problems to be Solved by the Invention) In the case of the conventional device described above, the roller 2 coated with the cleaning liquid is simply brought into contact with the sealing surface of the panel P.
The cleaning effect is low and dirt may remain on the sealing surface of the panel P, so in a later process, the panel P and funnel are sealed.
An electron gun is sealed in the neck of a valve consisting of a panel P and a funnel, and when the inside of the valve is evacuated, the panel P
In some cases, valves with insufficient sealing implosion due to dirt on the sealing surface of the valve.
なお、このバルブの爆縮の原因としては、ファンネルの
シール面の汚れもあるが、ファンネルの内面にはインナ
ーダグを塗布するだけなので、ファンネルのシール面に
汚れが残ることはほと/vど無く、パネルPのシール面
の汚れが爆縮の原因と考えられる。Note that one of the causes of valve implosion is dirt on the sealing surface of the funnel, but since Inner Dag is only applied to the inner surface of the funnel, there is very little dirt left on the sealing surface of the funnel. It is thought that dirt on the sealing surface of panel P was the cause of the implosion.
