Embodiment 1

[0037] A customer's heating requirement for the heating wire of the rear windshield of a type A car is: under 12V voltage, the overall temperature of the heating wire is <70 degrees.

[0038] Then adopt the present invention to make screen version, the screen version making of present embodiment comprises the following steps:

[0039] (1) Film production: use CAD in the computer to design the printed graphics of the heating wire of the rear windshield of the car according to the customer's needs, and then print out the printed film including the complete printed image of the busbar and sub-line through the photoplotter;

[0040] (2) Stretching: Stretch the 200-mesh screen for printing with a fully automatic stretching machine, and set the tension of the stretching to 18N / cm 2 ;

[0041] (3) Plate alignment: first place the printing film on the table in the yellow light chamber, and then place the P side of the screen on the top of the printing film (such as figure 2 As shown),...

Embodiment 2

[0050] A customer’s heating requirements for the heating wire of the rear windshield of a B-type car are: under 12V voltage, not only the overall temperature of the heating wire is required to be image 3 As shown, they are A zone, B zone and C zone which are symmetrical along the center line of the glass. Zone A is located in the middle of the glass and requires a heating power of 560±10% W / m 2 , Zone B is located on both sides of Zone A and requires a heating power of 410±10% W / m 2 , Zone C is located on both sides of Zone B and requires a heating power of 320±10% W / m 2 .

[0051] Then adopt the present invention to make screen version, the step that the screen version of present embodiment is made is as follows:

[0052] (1) Film production: use CAD in the computer to design the printed graphics of the heating wire of the rear windshield of the car according to the customer's needs, and then print out the printed film including the complete printed image of the busbar and ...

Abstract

The invention relates to a manufacturing method of an automobile glass heater wire printing screen plate, comprising the following steps: (1) manufacturing a bottom film; (2) tensioning a net; (3) performing alignment; 4)pasting the covering substrate; (5) photoresist coating; (6) drying; (7) exposure; (8) development; and (9) post-processing. Compared with the prior art, the method has the following advantages: A subbar and a bus bar are arranged on the same printing plate to produce a thickness difference between the two area of the photoresist, the thickness difference generated by the silver paste lay between the glass sub-bar and the bus bar area after glass printing is achieved, the temperature of each part of the glass is stable, At that same time, the invention can prevent the heatfrom generating at the welding joint of the bus bar from burning the silver paste, damaging the wrapping edge bar and causing burns of personnel, and can also meet the requirement of heating power differentiation of different parts of automobile glass.

Description

Technical field: [0001] The invention relates to a method for manufacturing a silk screen printing screen, in particular to a method for manufacturing an automobile glass heating wire printing screen. Background technique: [0002] Screen printing, in short, is to weave silk, synthetic fiber or metal wire into a net, stretch it tightly on the screen frame, and make a screen by manual engraving or photochemical plate-making. The principle of screen printing Yes: Utilize the photochemical changes of the photosensitive glue, that is, the light-receiving part of the photosensitive glue is cross-linked and hardened and firmly combined with the screen to form a plate film, and the unphotosensitive part is rinsed and developed with water or other developing solutions to form through holes, and the screen is made . The pattern part on the screen has through holes that allow ink to pass through, while the meshes of the non-graphic part are all blocked and ink cannot pass through. D...
