Abstract

The invention relates to a printing method capable of quickly aligning a glass substrate with a screen, which is characterized by comprising the following steps: firstly, drawing a frame diagram (4) at the center of a table (2) of a silk screen printing machine with an oil pen; secondly, putting a glass substrate in the corresponding position according to the position of the frame diagram (4), and vacuumizing to fix the glass substrate; thirdly, manually adjusting the screen frame according to the position of the frame diagram (4) observed from the hollow part of the screen until the diagram (4) is at the center of a screen diagram (3), and fixing the screen; fourthly, feeding slurry to print an experimental substrate, and manually adjusting the position of the glass substrate according to the error; and fifthly, after the position of the glass substrate is determined, making a mark with the oil pen. The invention has the advantage of high alignment efficiency, can not pollute or damage the screen, and is convenient and quick.

Description

The quick contraposition method of printing of glass substrate and half tone

Technical field

The present invention relates to a kind of manufacturing method for plasma displays, especially plasma scope front-back baseboard when printing to network method, the quick contraposition method of printing of specifically a kind of glass substrate and half tone.

Background technology

At present, shadow mask plasma display panel adopts the planar mask of using always in the color cathode ray tube CRT production in its manufacture craft be that the metal gate web plate substitutes barrier manufacturing complicated among the plasma display panel PDP, independent processing metal aperture plate plate, and make fluorescent material thereon.Shadow mask plasma display panel mainly comprises prebasal plate, metacoxal plate and shadow mask.Metacoxal plate comprises the back substrate glass substrate, on the back substrate glass substrate addressing electrode is arranged, and the dielectric layer of formation is being arranged on the backsight glass substrate of addressing electrode and form protective layer on dielectric layer; Prebasal plate comprises preceding substrate glass glass substrate, forms the scan electrode vertical with addressing electrode at preceding substrate glass substrate lower surface, is having and form dielectric layer on the preceding substrate glass substrate of scan electrode and at dielectric layer surface formation protective layer; Being clipped in the middle shadow mask of forward and backward substrate is by conductive material, the metal foil web plate that comprises the mesh array that for example iron or its alloy process.Will above-mentioned prebasal plate, charge into predetermined working gas after shadow mask and the metacoxal plate assembling sealing-in, various inert gases for example assemble in the mode of " sandwich " and to make whole screen, have promptly formed shadow mask plasma display panel.

In its manufacture craft, a lot of technologies are all used typography at shadow mask plasma display panel, as the preparation of addressing electrode, and the preparation of scan electrode, the preparation of dielectric layer, the preparation of MgO protective layer etc.In the laboratory, the shape of half tone and glass substrate varies especially, and that the local transparent characteristic of the transparent and half tone of glass substrate makes in the serigraphy is very low to net efficient, thereby influence print result, obstruction experiment process.

Summary of the invention

Purpose of the present invention be exactly in the serigraphy to netting slow problem, the method for a kind of glass substrate and the quick contraposition of half tone is provided, satisfying high efficiency, do not polluting half tone, the requirement that does not damage half tone realizes down fast the method to net.

The quick contraposition method of printing of a kind of glass substrate and half tone is characterized in that it may further comprise the steps:

A, slurry prepare, and the stirring box of packing into slurry to be printed clean stirs, it is standby to obtain slurry after the deaeration;

B, clean glass substrate 1 with cleaning machine;

C, the printing parameter of silk-screen printing machine is set;

D, at silk-screen table of printing machine 2 central parts with oil pen's framework figure 4 that draws, the framework of drawn framework figure 4 and half tone figure 3 is complementary and smaller;

E, according to the position of drawn framework figure 4, glass substrate 1 is placed on the corresponding position, by the vacuum hole on the silk-screen table of printing machine 25 glass substrate 1 is held the location;

F, the part figure 3 that sees through hollow out on the half tone are observed the position of framework figures 4; The position of manual adjustments half tone figure 3 makes half tone figure 3 be in the central authorities of framework figure 4, then half tone is fixed;

G, spreading mass print experiment slice, manually adjust the position of glass substrate 1 according to error;

H, repetition previous step until the satisfied setting value of the error of experiment slice printing, can be determined the position of glass substrate 1, carry out the position mark of glass substrate then with the oil pen;

I. print formal sheet.

The invention has the beneficial effects as follows:

The present invention has bit rate fast, and simple advantage can not polluted half tone, can not damage half tone.

Description of drawings

Fig. 1 is a mark line schematic diagram of the present invention.

Fig. 2 is a substrate contraposition schematic diagram of the present invention.

Fig. 3 is of the present invention to the net principle schematic.

The specific embodiment

Below in conjunction with drawings and Examples content of the present invention is further described.

As shown in Figure 1, 2, 3.

The quick contraposition method of printing of a kind of glass substrate and half tone, it may further comprise the steps:

B, clean glass substrate 1 with cleaning machine;

C, the printing parameter of silk-screen printing machine is set;

D, at silk-screen table of printing machine 2 central parts with oil pen's framework figure 4 that draws, the framework of drawn framework figure 4 and half tone figure 3 is complementary and smaller; Make drawn framework figure 4 not only clear but also difficultly fallen by erasing; As Fig. 1, in order to make with framework figure 4 can not form influence to formal printing, the height of framework figure 4 projection on table of printing machine 2 should be less than 1 micron;

E, according to the position of drawn framework figure 4, glass substrate 1 is placed on the corresponding position, by the vacuum hole on the silk-screen table of printing machine 25 glass substrate 1 is held the location; As shown in Figure 2;

F, the part figure 3 that sees through hollow out on the half tone are observed the position of framework figures 4; The position of manual adjustments half tone figure 3 makes half tone figure 3 be in the central authorities of framework figure 4, then half tone is fixed; As shown in Figure 3;

H, repeat print experiment slice 2-3 time, satisfy setting value, can determine the position of glass substrate 1, carry out the position mark of glass substrate 1 then with the oil pen until the error of experiment slice printing;

I. print formal sheet.Only needing during printing that glass substrate is placed on the top mark of being done gets final product.

The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
