Embodiment Construction

[0024] see figure 1 and image 3 , a screen printing fixture 100, including a base plate 110 and a pressing mechanism, the base plate 110 is provided with a cavity 120 that can fit with a clearance of the workpiece 200 to be printed, and the base plate 110 includes an opposite first inner wall 121 and a second inner wall 122 , the first inner wall 121 and the second inner wall 122 are both inner walls of the cavity 120 . The first inner wall 121 is provided with a chute groove 130, the pressing mechanism is slid in the chute groove 130 and can abut against the to-be-printed piece 200, and the pressing mechanism compresses the to-be-printed piece 200. The printing part 200 , so that the side of the printing part 200 is closely attached to the second inner wall 122 .

[0025] Specifically, the shape, structure and size of the bottom plate 110 can be processed and formed according to the needs of actual production. Generally, the bottom plate 110 is a rectangular parallelepiped...

Abstract

A silk-screen printing fixture comprises a bottom plate and a pressing mechanism, wherein a cavity which can be in clearance fit with a to-be-printed piece is formed in the bottom plate; the bottom plate comprises a first inner wall and a second inner wall which are opposite; a slide way groove is formed in the first inner wall; the pressing mechanism is glidingly arranged in the slide way groove and is propped against the to-be-printed piece; and the pressing mechanism tightly presses the to-be-printed piece and tightly attaches the side surface of the to-be-printed piece to the second inner wall. When the silk-screen printing fixture is required for printing patterns, such as a window or keys and the like, on the to-be-printed piece such as a piece of glass of a cover plate of a mobile phone, the to-be-printed piece is placed in the cavity formed in the bottom plate, and the pressing mechanism tightly presses the to-be-printed piece to the second inner wall opposite to the first inner wall, so that the influences of fit clearance on positioning of the to-be-printed piece is reduced, the fit clearance between the silk-screen printing fixture and the to-be-printed piece can even be eliminated, the positioning accuracy of the window, the patterns and the like of the to-be-printed piece is improved, and accurate positioning is realized.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a screen printing jig and a method for using the same. Background technique [0002] The touch screen is an input device to improve the man-machine interface, which has the advantages of intuition, simplicity and speed. Touch screens are widely used in various electronic products, such as mobile phones, PAD (Personal Digital Assistant, personal digital assistant), multimedia, and public information inquiry systems. [0003] Glass used to make touch screens, such as mobile phone cover glass, usually needs to be printed with patterns such as windows, buttons, and LOGO. These patterns are generally completed by silk screen printing. Due to the relatively high positioning accuracy of these patterns, glass screen printing generally uses the cooperation between glass and screen printing fixtures for shape positioning. However, the fit gap between glass and screen printing fixtur...
