Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in with reference to the accompanying drawings and the detailed description.

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only partial embodiments of of the present invention, rather than all embodiments.

In the description herein, reference to the terms " embodiments," " embodiments," "examples," "specific examples," or " examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least embodiments or examples of the invention.

Laser refers to laser (stimulated emission light amplification) in which atoms are stimulated to emit light, so called "laser", in which electrons in atoms absorb energy and then transit from a low energy level to a high energy level, and when the electrons fall back from the high energy level to the low energy level, the released energy is emitted in the form of photons, and the attracted (excited) photon beam (laser) has photon optical characteristics of height .

As shown in fig. 2, in the conventional exposure and screening method, a light source 34 is scattered onto a glass 32, and then the photosensitive paste 1 is exposed through the glass 32 and a film (master 31) to cause chemical reaction hardening of the photosensitive paste 1, the light 33 of the light source 34 is blocked by the master 31 in a black area, and the photosensitive paste 1 on the upper portion is not subjected to photosensitive hardening. The exposure screening method is realized by penetrating and refracting light 33 scattered by a light source 34, and the penetrating and refracting characteristics generated in the exposure process can generate the bad effect of jagged edges of an exposure area.

As shown in fig. 1 and 3, the method for manufacturing kinds of ink silk screen plate laser screen printing plates provided by the invention comprises the following steps:

s100 coating/immersing the screen 2 with the photosensitive paste 1 for pre-curing. Among them, the photosensitive paste 1 is also called photosensitive emulsion, photoresist, and it and photosensitive film (also called film) are currently commonly used photosensitive materials.

S200, placing the pre-cured screen 2 in a frame area of a laser machine and fixing the screen (two adjacent sides of a screen clamping frame are fixed, the other two sides are movable and adjustable, when the screen frame is placed on a frame, the movable two sides push the screen frame to the tightest position and clamp the screen frame), and setting a zero point of the screen 2;

s300, importing data to be radiussed in an external controller into a processor of laser machine equipment, setting a laser beam zero point and adjusting operation parameters of a laser screen drying function, and inputting exposure scanning power 175mA, scanning speed 200mm/S and specific numerical values of actual width and height of a framework of a screen 2;

s400, starting laser machine equipment, aligning the zero point of the screen printing plate 2 and the zero point of a laser beam, and operating a laser screen drying function;

s500, automatically performing laser drawing of photosensitive hardening on the screen 2 by using the laser beam until all drawing is completed;

s600, washing the laser-painted screen printing plate 2 by using high-pressure water, and washing away the photosensitive paste 1 in the area which is not subjected to laser painting;

s700, the screen printing plate 2 washed by the high-pressure water is solidified again, and the screen drying process is completed.

In other more specific embodiments, before the step of coating/immersing the screen 2 with the photosensitive paste 1 for pre-curing, the method further comprises the following steps:

analyzing the data to be radiussed, and confirming that the orientations of all characters are reversed characters;

the analyzed data and the actual expansion and contraction coefficient of the data are input into an external controller.

The laser beam automatically performs laser drawing of photosensitive hardening on the screen 2 until all the steps of drawing are completed, and the method further comprises the following steps: and checking the screen drying effect of the laser drawing of the screen 2 under the light table.

The screen 2 is formed by arranging ink silk screen gauze on the screen frame to be tensioned to preset tension.

The laser beam is a red UV laser beam 41 emitted by a laser head 42, the diameter of the beam is 5-10 microns, UV laser drawing is carried out on a photosensitive area on laser data to be subjected to laser drawing, and the area which is not subjected to UV drawing needs to be washed away, so that the manufacturing requirement of a screen printing plate is met. Because the diameter of the laser beam is smaller, the problem of jagged edges in the traditional exposure manufacturing method is avoided.

And curing the screen printing plate 2 washed by the high-pressure water again, wherein in the step of finishing the screen drying process, the curing again is to put the screen printing plate 2 into an oven for baking and curing for 30-40min at the temperature of 140-160 ℃.
