Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is an apparatus for manufacturing a fluorescent screen for a color cathode-ray tube, and particularly when an antistatic panel is mounted on the head and hydrofluoric acid is washed, a hydrofluoric acid solution is applied to the panel face surface. The present invention relates to a panel holding device that prevents the fluff.

[Conventional technology]

Conventionally, when cleaning the antistatic panel in the hydrofluoric acid cleaning section, a method of covering the panel face surface and the middle of the skirt with a resin sheet has been adopted. That is,
A person attaches a cover to each of the panels with a sheet and attaches the cover to the head to prevent appearance defects such as a panel face surface due to a fluoric acid solution splash in a cleaning process.

[Problems to be solved by the device]

In the above-mentioned conventional method, the hydrofluoric acid liquid is splashed or permeated from between the panel and the sheet cover during the hydrofluoric acid cleaning, the antistatic film for the panel is covered, and the appearance is deteriorated. Also, since a person must attach a seat cover to each panel,
It has a drawback that it takes time and is not suitable for mass production.

An object of the present invention is to provide a panel holding device that solves the above problems.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, a panel holding device according to the present invention is a panel holding device used in a hydrofluoric acid cleaning process of a manufacturing apparatus of a color cathode ray tube and a fluorescent film.
It is equipped with a rubber pedestal that fits closely to the panel according to the curvature of the panel.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

1 is a diagram showing an embodiment of the present invention, FIG. 2 is a diagram showing a panel mounting portion of a head, FIG. 3 is a diagram showing a pedestal, FIG. 4 is a diagram showing an antistatic panel, and FIG. The figure shows an outline of the hydrofluoric acid cleaning unit.

In the drawings, in order to prevent permeation of hydrofluoric acid on the force surface and skirt of the antistatic panel 1,
The rubber pedestal 6 is manufactured with a mold according to the curvature dimension of the panel 1, and since the panel surface contact portion of the pedestal 6 uses soft rubber, it is further softened by heat in other steps (drying section). Considering that it becomes harder and thus easily deformed, the pedestal 6 has a structure in which a metal plate 7 is inserted as a bone in the central portion. In addition, a pedestal collar 5 is provided on the side of the pedestal 6 to attach the head 8
It is adapted to be attached to the substrate 3 of.

According to the present invention, since the panel 1 is brought into close contact with the rubber pedestal 6 matched to the curvature dimension of the panel 1, it is possible to prevent the permeation and permeation of hydrofluoric acid.

The panel guide 2 is screwed to the substrate 3 attached to the head 8 shown in FIG. Antistatic panel 1
The panel guide 2 is removed and the pedestal 6 of FIG. When the pedestal 6 is attached to the substrate 3, the pedestal 6 is positioned so that the center of the substrate 3 is aligned with the center of the substrate 3. After positioning, pedestal collar 5
To the substrate 3 with screws. FIG. 1 shows a state in which the rubber pedestal 6 and the panel 1 are attached to the panel mounting portion of the head, and the antistatic panel 1 is fixed by the panel clamp arm 4.

As shown in FIG. 5, in the hydrofluoric acid cleaning portion, the antistatic panel 1 requiring cleaning is rotated by the pump P while rotating downward.
At this point, hydrofluoric acid is ejected to wash.

[Effect of device]

As described above, according to the present invention, by attaching the rubber pedestal, the antistatic panel and the pedestal can be brought into close contact with each other, and the hydrofluoric acid solution does not splash or permeate during cleaning, so that no external appearance defect occurs. As a result, it is not necessary to attach a seat cover to each panel, which has an effect of being optimal for mass production.
