A new type of woven meshless mesh plate making method

Abstract

The invention discloses a novel weaving method for making a knotless screen plate, the steps are as follows: S1, wire mesh weaving; S2, stretching the net; S3, exposure and development; Interlaced weaving is carried out to form a mesh, so that when the metal weft and metal warp need to be cut during grid line printing without mesh, the number of cutting points is reduced and the working efficiency is improved.

Description

technical field [0001] The invention relates to a novel weaving method for making a knotless screen plate. Background technique [0002] Screen printing technology is an ancient civilization and a long-lasting industry, which is widely used in people's production and life. Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has emerged. The basic structure of the screen is eternal, that is, the screen frame, the printing screen and the photosensitive material for printing are integrated, and the three are indispensable; Figure 5 with 6 As shown, the current mesh yarn 6 is generally formed by interlacing each metal weft thread 62 and each metal warp thread 61, and then generally by coating the photosensitive glue on the mesh yarn 6 when making the grid line 63, and then Clean the printed grid line area after ultraviolet exposure, and when making the non-mesh grid line 63, ...

Especially in recent years, with the high development of the electronics industry, the screen printing process has been well applied, and a vibrant scene has emerged. The basic structure of the screen is eternal, that is, the screen frame, the printing screen and the photosensitive material for printing are integrated, and the three are indispensable; Figure 5 and 6 As shown, the current mesh yarn 6 is generally formed by interlacing each metal weft thread 62 and each metal warp thread 61, and then generally by coating the photosensitive glue on the mesh yarn 6 when making the grid line 63, and then Clean the printed grid line area after ultraviolet exposure, and when making the non-mesh grid line 63, the grid line 63 needs to be made in the middle area of ​​the adjacent metal weft line 61 or the warp line 62, so that the grid line 63 does not touch Mesh interlaced node, and according to the width requirement of grid line 6 is different, or because metal weft 61 and warp 62 bend, the spacing between adjacent metal weft 61 and metal warp 62 is uneven, so that metal weft 61 and warp 62 are bent. The metal warp 62 is in contact with the non-mesh grid line 63, which affects the shape and size of the non-mesh grid line 63. At this time, it is necessary to cut the metal weft 61 and the warp 62 of the part in the mesh yarn to increase the adjacent weft 62 and the warp 62. The spacing between adjacent warps 61, but if each metal weft and each metal warp are interlaced, there are many points that need to be cut when the mesh yarn cuts the weft 62 and warp 61, which greatly reduces the operating efficiency. like Figure 5 As shown, there are five cutting points 64, which are formed after the cutting is completed. Image 6 The larger width of the non-mesh grid line 63, or keep the original size, the purpose of cutting is to prevent the adjacent metal weft 61 from bending to contact the non-mesh grid line 63, increasing the spacing to avoid the possibility of contact

[0003] In addition, the way of exposing on the mesh is generally to paint the photosensitive glue on the mesh, then heat and cure the photosensitive glue on the mesh, and then expose and wash the photosensitive glue on the mesh through negative film exposure. Finally, the screen printing pattern is obtained, and the photosensitive glue in this way is directly painted on the mesh, the stability is not good, the photosensitive glue is unevenly painted and the thickness cannot be controlled, which affects the printing performance of the printed pattern
