Embodiment 1

[0016] The invention provides a precision screen sand engraving processing method, comprising the steps of:

[0017] 1. Stretching net: Paste the metal wire mesh on the screen frame tightly to form a screen version. The metal wire mesh is suitable for any weaving mesh, any weaving method, and any metal material with any profile characteristics. It is stainless steel wire mesh, Stainless steel sheet, electroformed mesh, alloy wire mesh and other metal mesh yarns;

[0018] 2. Sand carving treatment:

[0019] (1) Put the stretched wire mesh into the sand engraving equipment, add 1200 mesh corundum into the sand engraving equipment, and cover the non-sandblasting area of ​​the screen with a cover cloth;

[0020] (2) The pressure of the sand engraving equipment is set to 0.35 MPa, the emery is sprayed out, and the surface of the wire mesh of the screen is sprayed for 60 seconds to obtain a sand engraved screen;

[0021] 3. Degreasing: Degrease the sand-cut screen to remove ...

Embodiment 2

[0026] The present invention provides a precision screen sand engraving processing method, the rest of the steps are similar to Embodiment 1, and the sand engraving processing steps are:

[0027] (1) Put the stretched wire mesh into the sand engraving equipment, add 600 mesh silica particles into the sand engraving equipment, and cover the non-sandblasting area of ​​the screen with a plastic film;

[0028] (2) The pressure of the sand engraving equipment is set to 0.25 MPa, the silicon dioxide particles are sprayed out, and the surface of the wire mesh of the screen is sprayed for 114 seconds to obtain a sand engraved mesh. Version.

[0029] The precision screen sand engraving treatment method disclosed by the present invention can roughen the surface of the metal screen, increase the adhesion of the screen surface, and ensure better contact between the screen and the photosensitive layer in the subsequent coating process. The surface of the screen is sand-cut to form uniform...

Abstract

The invention discloses a sand carving processing method of a precision screen printing plate. The sand carving processing method comprises the following steps: placing a metallic screen mesh stretched by a stretching mesh into sand carving equipment, and adding sand carving particles in the sand carving equipment; ejecting the sand carving particles under pressure by the sand carving equipment, coarsening the surface of the metallic screen mesh, and ejecting for 30-300 seconds so as to obtain the precision screen printing plate through sand carving processing. Through the manner, according to the sand carving processing method of the precision screen printing plate provided by the invention, the surface of the metallic screen mesh can be coarsened, the adhesive force of the surface of the screen mesh is increased, good contact between the screen mesh and a photosensitive layer in the subsequent coating working procedure is ensured, uniformly and densely distributed frosted pits are formed in the surface of the screen mesh after the sand carving processing, the effect of mirror reflection for original metallic material cannot appear, and the phenomena of scattering and reflection conditions of light during plate burning process are reduced, so that the images are clear during the subsequent plate burning process, the definition and tangent performances of lines are good, and the transfer amount of printing oil ink is increased.

Description

technical field [0001] The invention relates to the processing technology of high-precision metal screens such as solar cells, touch screens, and microelectronics, and in particular to a method for processing precision screens by sand engraving. Background technique [0002] During the production process of the screen printing screen, because the surface of the wire mesh is very smooth, the photosensitive layer covering the surface of the wire mesh has limited bonding strength with it. During the printing process, the repeated scraping of the printing rubber strip will cause the photosensitive layer of the screen to fall off, resulting in defects such as pinhole leakage, which will reduce the life of the screen printing. In addition, the bright metal surface will cause excessive scattering and reflection during the printing process, and the fine line resolution performance will be affected. The increasingly sophisticated screen printing screen production requirements. Con...
