Abstract

Panel washing apparatus for cathode ray tube comprises and is mounted to the cleaning roller that can be rotated, move forward and backward with operating means, and processing is at the groove of cleaning roller outer periphery and be used for rinse water is ejected into nozzle in the groove.Thereby can reduce the rinse water backwash in the groove and boost productivity to reduce panel ratio inferior by rinse water is ejected into.

Description

Panel washing apparatus for cathode ray tube
The present invention relates to panel washing apparatus for cathode ray tube, more precisely, relate to equipment with the improvement cleaning roller that is used for the inner surface of cleaning surface panel edges.
Generally speaking, the screen of being made up of fluorescence striped or point, black substrate and metal coating is processed the surface, inside at the face-plate of a cathode-ray tube.The process of making screen comprises steps such as forming black substrate, formation fluorescence striped and formation metal coating.More particularly, the step of formation fluorescence striped comprises: the fluorescence slurry applies, exposes, develops.Form in front during the step of fluorescence striped, light slurry and other sediment are coated in the edge and the bottom of the panel that forms screen.Also should increase the step that the fluorescence slurry that applies on need not the position of fluorescent material and sedimental panel are cleaned.
The used conventional cleaning equipment of this cleaning step as shown in Figure 1.
Panel washing apparatus have the cleaning roller 3 of a cylinder form that makes it to rotate by the slewing of determining '.Cleaning roller 3 ' contact with the panel 2 edge inner surfaces that grip rotation by load head 1.Cleaning roller 3 ' be mounted to is rotatable with this equipment, can advance and can retreat.Be used to provide the nozzle 5 of rinse water to place to be adjacent to cleaning roller 3 ' locate.
The situation roller 3 of the structure conventional panel washing apparatus that is used for cathode ray tube as above ' wipe relict sediment on the panel 2 marginal portion inner surfaces.When cleaning roller 3 ' work, rinse water makes cleaning more effective from nozzle 5 ejections.
In aforementioned conventional cleaning equipment,, impact roller avris part by the rinse water that nozzle provides when with rotation cleaning roller 3 ' when cleaning.Its shortcoming is that some rinse water is splashed on the inner surface of the panel that forms the fluorescence striped.
If panel fluorescence striped is when the rinse water of backwash is washed away roller and stain, because the pollution on the panel and can not use this fluorescence striped.
The purpose of this invention is to provide the improved panel washing apparatus that the rinse water that can effectively prevent the nozzle ejaculation that is used for cathode ray tube splashes cleaning roller.
For realizing this purpose, the panel washing apparatus for cathode ray tube that provides comprises and is mounted to the cleaning roller that can rotate, can advance, can move back and is used for rinse water is ejected into nozzle on the cleaning roller.
Wherein forming along the cleaning roller excircle has cannelure, makes rinse water inject this groove and nozzle is installed.
By means of following explanation with reference to the accompanying drawings, other purpose of the present invention and advantage become more clear.In the accompanying drawing,
Fig. 1 is conventional panel washing apparatus diagrammatic depiction;
Fig. 2 is the diagrammatic depiction of panel washing apparatus of the present invention;
Fig. 3 is the part of another embodiment middle roller of the panel washing apparatus of the present invention view that cuts section;
Fig. 4 is the end view of another embodiment middle roller of panel washing apparatus of the present invention.
With reference to figure 2, panel washing apparatus comprises: improved roller 3, the operating means (not showing) that is used to provide the nozzle 5 of rinse water and is used to operate roller 3.
Panel 2 is by load head 1 clamping, and cleaning roller can be rotated by operating means cleaning roller 3, the forward and back operation with panel 2 edges tight contact the in inner surface.The nozzle 5 of jet cleaning water places near washing roll 3 side surfaces, according to characteristic of the present invention, along cleaning roller 3 outer peripheries processing cannelure 4, is installed in the nozzle 5 of jet cleaning water near the groove 4 and aims at this groove.As shown in Figure 3, preferably the section of the groove 4a of cleaning roller 3 is processed into wedge shape.And for example shown in Figure 4, more preferably groove 4b is processed into ripple dress pattern or indentation.
As above Gou Zao panel washing apparatus for cathode ray tube of the present invention is characterised in that, panel washing apparatus comprises the cleaning roller 3 and the nozzle 5 that places groove 4 vicinity that cannelure 4 is arranged along its side surface.The groove 4 that is fed to cleaning roller 3 from the rinse water of nozzle 5 ejection makes rinse water flow along groove 4 to brush fluorescent material and other deposit of sticking to the inner surface of panel.
Can effectively reduce the contamination on rinse water counter plate 2 inner surfaces by feature of the present invention.
Particularly, can strengthen the effect that reduces the rinse water pollution by the groove 4a of wedge shape shown in Figure 3 greatly.Except that wedge-shaped slot, because the big zone of rinse water supply range panel edges part, also can strengthen cleaning performance with the groove 4b of wavy pattern shown in Figure 4.
As mentioned above, according to the panel washing apparatus of cathode ray tube of the present invention, when the inner surface of face plate edge is cleaned, reduced the pollution on the inner surface of rinse water counter plate owing to groove along the cleaning roller Surface Machining.Therefore, thus the ratio of the panel inferior that produces during the cleaning step significantly descends and has improved productivity ratio.

Claims (3)
