本発明はブラウン管のパネルシール面側洗浄袋ＷｔＥこ
関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning bag WtE for the panel seal side of a cathode ray tube.

はねると、有効表示面のけい光膜（こ悪影響を及ぼす。In the phosphor film coating process, which is the manufacturing process for cathode ray tubes, excess materials such as graphite, phosphor, and emulsion (acrylic film) adhering to the panel seal surface, skirt portion, and pin portion of the cathode ray tube are removed. Washing is being done. This cleaning of excess material on the panel seal surface side is generally carried out by a dip cleaning method in which the panel seal surface side is immersed in a cleaning liquid in a cleaning tank. However, in this method, by lifting the panel immersed in the cleaning liquid, the liquid film that is generated when the panel seal surface separates from the liquid surface breaks and becomes droplets that splash. If these droplets splash on the inside of the panel, they will adversely affect the fluorescent film on the effective display surface.
従来、液滴がパネル内側ｆこはねるのを防止する洗浄装
置として、例えば実開昭５７−１０３６６０号公報に示
すように、パネル内側にエアーを流し、液滴を外側へ押
し出している。Conventionally, as a cleaning device for preventing droplets from bouncing around inside a panel, as shown in, for example, Japanese Utility Model Application Publication No. 57-103660, air is flowed inside the panel to push the droplets outward.

とがある。特に、パネルの傾き精度が悪いと、多く発生
する。With the above conventional technology, it is difficult to blow air uniformly outward from the entire circumference of the panel sealing surface, and the weakest liquid film part breaks outward first, air escapes from that part, and other parts Droplets (on the opposite side) may splash inward. In particular, this problem often occurs if the tilt accuracy of the panel is poor.
本発明の目的は、パネルシール面と液面と１こできる液

ができるブラウン管のパネルシール面側洗浄装置を提供
することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device for the panel seal surface of a cathode ray tube, which can uniformly push out a liquid film formed between the panel seal surface and the liquid surface over the entire circumference of the panel.
上記目的は、洗浄液をパネル円面側からパネル外側へ流
れるように制御する液流制御手段を設けることｆこより
達成される。The above object is achieved by providing a liquid flow control means for controlling the cleaning liquid to flow from the circular side of the panel to the outside of the panel.
パネル内面側からパネル外側に流れる液流ｉこより、パ
ネルシール面と液面にできる液膜は外側へ押し流される
ので、パネル内面１こ液滴がはねるのは防止される。Due to the liquid flow flowing from the inner surface of the panel to the outer side of the panel, the liquid film formed on the panel sealing surface and the liquid surface is swept outward, so that droplets on the inner surface of the panel are prevented from splashing.

り、ＮＩＬイブ５を通して液体が供給される。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. As shown in FIG. 1, a ventilation hole 2 is provided in the center of the cleaning tank higher than the top surface of the cleaning tank l. A liquid flow control nozzle 4 is disposed on the outer periphery of the vent hole 2 to blow out the same liquid as the cleaning liquid 3 in an upward direction as indicated by arrow A. Liquid is supplied through the NIL tube 5.

and remove any excess material stuck to the pin. Then, when the panel 6 is lifted up in the direction of arrow B, the same liquid as the cleaning liquid 3 is supplied to the pipe 51, and the liquid is blown out in the direction of arrow A from the liquid flow control nozzle 4. As a result, as shown in FIG.
The liquid film 3a that is generated when the sealing surface of is separated from the liquid surface is pushed out to the outside of the panel 6 by the liquid fit in the direction of arrow C, and the droplets caused by the liquid film 3at are pushed out in the outward direction as shown by the arrow. Therefore, droplets are prevented from splashing onto the circular surface of the panel 6.

Further, instead of the liquid flow control nozzle 41, other liquid flow control means may be used.
本発明によれば、パネルシール面と液面ｆこできる液膜

となり、歩留りが向上する。According to the present invention, the liquid film that forms on the panel sealing surface and the liquid surface is pushed out to the outside of the panel, so there is no droplet splash failure and the yield is improved.
