Embodiment 1

[0027] A master-plate synthesis alignment process, comprising the following steps:

[0028] (1) Synthesize the large-aperture master of the required graphics:

[0029] (1) Utilize the large-aperture original master to copy a plurality of first film plates, and the graphics formed on the copied first film plates are the same as those on the large-aperture original master; the copying conditions are: use the exposure machine to vacuumize Under the conditions of system vacuum pumping, semi-vacuum pumping 20S, and full vacuum pumping 50S, the large-aperture original master plate is used as a mask and the film is tightly combined for exposure. The exposed luminous flux is 65lm; 25°C developer solution to develop the exposed film, so that the pattern formed on the film is the same as that on the original large-aperture master; then use a 38°C fixer to form a black and white stable pattern on the film; and then After fixing, the film is washed with water, the developer and fixer on ...

Embodiment 2

[0041] A master-plate synthesis alignment process, comprising the following steps:

[0042] (1) Synthesize the large-aperture master of the required graphics:

[0043] (1) Use the large-aperture original master to copy multiple first film plates; the copying conditions are: use the vacuum pumping system of the exposure machine to pump air, semi-vacuum pumping for 30S, and full-vacuum pumping for 75S under the condition of large-aperture The original master plate is exposed by the close combination of the mask and the film, and the exposure luminous flux is 90lm; then use a developing machine, using a developer with a working temperature of 36°C, to develop the exposed film, so that the film is formed on the film. The same graphics as the master; then use a fixer solution at 36°C to form a black and white stable graphic on the film; then wash the fixed film with water to remove the developer and fixer solution on it, and then heat it under the condition of 43°C Drying for 40S;...

Embodiment 3

[0055] A master-plate synthesis alignment process, comprising the following steps:

[0056] (1) Synthesize the large-aperture master of the required graphics:

[0057] (1) Use the large-aperture original master to copy multiple first film plates; the copying conditions are: use the vacuum pumping system of the exposure machine to vacuum, semi-vacuum pumping for 50S, and full vacuum pumping for 100S under the condition of large-aperture The original master plate is exposed by the close combination of the mask and the film, and the exposure luminous flux is 120lm; then use a developing machine, using a developer with a working temperature of 38°C, to develop the exposed film, so that the film is formed on the film. The same pattern as the master; then use a fixer at 25°C to form a black and white stable pattern on the film; then wash the fixed film with water to remove the developer and fixer on it, and then place it under the condition of 37°C Drying for 35S; the first film pl...

Abstract

The invention relates to the field of color picture tube manufacturing, in particular to a master synthesis and contraposition process. In the prior art, a new master with new patterns consisting of a plurality of original master patterns repeatedly arranged is manufactured on a laser-beam plotter, and the cost of manufacturing the new master is high. The master synthesis and contraposition process comprises the following operating steps: copying a plurality of first films by a largeaperture original master; cutting unused parts of the first films; splicing and fixing the plurality of cut first films; copying a largeaperture master by the spliced and fixed first films; copying a plurality of second films by a small-bore original master, and cutting unused parts of the second films; taking the largeaperture master as reference, and performing accurate contraposition on the cut second films and the largeaperture master; fixing the plurality of second films; and finally, copying a small-bore master by the second films fixed in contraposition. The master synthesis and contraposition process has low cost of manufacturing the master, and accurate contraposition of the largeaperture and small-bore masters.

Description

1. Technical field [0001] The invention relates to the field of color picture tube manufacturing, in particular to a master plate synthesis alignment process. 2. Background technology [0002] In the color picture tube manufacturing industry, the production of screen plates requires double-sided exposure and double-sided etching of steel strips using working plates. Then the relative position of the graphics on the working plates on both sides of the steel belt must be accurately guaranteed, so the graphics on the large and small aperture working plates have accurate alignment, so as to ensure that the produced screen can meet the use requirements. The working plate is manufactured by copying the master plate, so it is required that the graphics on the large and small aperture master plates have accurate alignment. On the other hand, since the size requirements of the graphics on the master are very high, making a new master needs to be carried out on a dedicated high-preci...
