Problems solved by technology

[0003] At present, the tolerance of the screen printing of the cover plate is relatively large, and generally can only be controlled within ±0.1mm, and as the mesh is deformed or blocked by ink during the screen printing process, jagged edges (≈0.1mm) are easily formed on the edge of the pattern, resulting in The appearance is poor, so it is difficult to meet the production of fine patterns

Embodiment 1

[0058] Such as figure 1 As shown, an initial frame pattern 10 is screen-printed on the panel 100 by screen printing technology, and the initial frame pattern 10 includes positioning targets 20 . combine figure 2 , the panel 100 is a rectangle, the inner edge of the initial frame pattern 10 and the inner edge of the target frame pattern 30 are both rectangular, and the edge of the panel 100 includes the first side 101 of the panel, the second side 102 of the panel, and the third side of the panel, which are sequentially connected clockwise. Side 103 and panel fourth side 104, the inner edge of target frame pattern 30 comprises target first side 31, target second side 32, target third side 33 and target fourth side 34, target first side 31 is parallel to and adjacent to the first side 101 of the panel, and the inner edge of the initial frame pattern 10 includes an initial first side 11, an initial second side 12, an initial third side 13, and an initial fourth side 14, which a...

Abstract

A frame pattern silkscreen method comprises the following steps that S1, an initial frame pattern is silkscreened on a panel and comprises a locating target; S2, the edge of the panel and the locating target are identified through a visual identification system, so that the initial frame pattern is located, the initial frame pattern and a target frame pattern are compared, and a non-target frame pattern area is determined; and S3, the non-target frame pattern area is etched through a laser etching process, and thus the final frame pattern is formed on the panel. According to the frame pattern silkscreen method, precise comparison of the visual identification system and the high precision characteristic of laser etching are combined with a silkscreen process, thus the non-target frame pattern area is removed precisely, silkscreen tolerance is improved effectively, thereby being controlled within the range of 0.06 mm, deviation caused by the silkscreen tolerance is reduced, meanwhile, the edge sawtooth effect of the silkscreen pattern can be improved, thus the edge of the pattern is flat and smooth, and the printing requirements of the fine pattern are met.

Description

technical field [0001] The invention relates to the technical field of silk screen printing, in particular to a screen printing method for frame patterns. Background technique [0002] Screen printing is to use the characteristics of the mesh of the graphic part of the screen printing plate to penetrate the ink, and the mesh of the non-graphic part to impervious to the ink. Through a certain pressure, the ink is transferred to the substrate through the mesh of the graphic part of the screen printing plate. On the surface, a picture and text that is basically consistent with the original manuscript is formed. Screen printing has the characteristics of simple equipment, convenient operation, simple printing and plate making, low cost, and strong adaptability. It is widely used in the cover plates of LCD, mobile phones, tablets and other electronic products. With the pursuit of high screen-to-body ratio by consumers, the screen printing frame pattern of the cover plate is requ...
