A workpiece positioning structure and a screen printing positioning tool for a display protection screen

Abstract

The invention discloses a workpeice positioning structure and a silk-screen printing positioning tool for a display protecting screen. The positioning tool comprises a positioning plate, wherein at least one positioning groove for accommodating the display protecting screen is concavely formed in the positioning plate; at least two positioning groove walls and accommodating groove walls are formed in the positioning grooves; the at least two positioning groove walls are intersected or in extending intersection and are used as positioning references so as to contact and support against the display protecting screen; and the accommodation groove walls are in clearance fit with the display protecting screen. The positioning structure further comprises an elastic member, wherein during use, the elastic element is supported against and matched with the display protecting screen and applies a force on the display protecting screen so as to enable the display protecting screen to be supported against and contacted with the positioning groove walls, then the display protecting screen can be fixed in the positioning grooves. During use, the positioning grooves which are intersected or in extending intersection are used as the positioning reference sides, so that accurate positioning for the display protecting screen on a plane is effectively realized; and in addition, under the action of the elastic element, the display protecting screen is supported against the positioning groove walls used as the positioning reference sides and the positioning precision of the positioning mode can be further ensured.

Description

technical field [0001] The invention belongs to the technical field of positioning tooling, and specifically relates to a workpiece positioning structure for positioning workpieces. At the same time, the invention also relates to a screen printing positioning tool for a display protection screen using the positioning structure. Background technique [0002] With the development of science and technology, technological products such as computers, mobile phones, and palm treasures have penetrated into people's daily life, and consumers have higher and higher requirements for the quality of technological products. Display protection screens occupy an important position in high-tech products such as computers, mobile phones, and handheld treasures. The quality of their manufacturing directly affects the choice of high-tech products for ordinary consumers. [0003] The display protection screen is made by printing various graphic patterns on a glass with special requirements by s...

Problems solved by technology

[0004] The structure of the existing display protection screen display protection screen positioning tool is as follows: figure 1 , figure 2 As shown, the positioning plate 3 is included, and the positioning plate 3 is evenly distributed with square positioning grooves 5 for holding the display protection screen 4 to be printed and adapted to the shape of the display protection screen, but for the convenience of display protection screen 4 is put into the square groove 5, and it is convenient to take out the display protection screen after processing from the square groove. The four sides of the display protection screen 4 cooperate with the groove side walls around the square groove 5, but the position Low positioning accuracy and high printing defective rate

[0005] When the above-mentioned positioning tool is used, the display protection screen is usually directly put into the square groove, and the four sides of the display protection screen and the side walls of the square groove around the groove are in clearance fit, so that not only the positioning of a single printing The accuracy is difficult to guarantee. At the same time, there are certain differences in the printing quality of each batch, which affects the processing quality of the display protection screen.
