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.

Embodiment Construction

[0026] Such as Figure 3 to Figure 7 As shown, an embodiment of a screen printing positioning tool for a display protection screen, the positioning tool in this embodiment includes a positioning plate 13 in a square structure, and the circumferential edge of the positioning plate 13 has two pairs of adjacent and intersecting Vertical base edge. On the positioning plate 13, four positioning grooves 15 for holding the display protection screen 14 are recessed. The positioning grooves are a square groove structure suitable for the appearance of the display protection screen. Among them, the two adjacent groove side walls are two positioning groove walls 151 and 152 used as positioning reference sides to release the pressure on the display protection screen, and the other two adjacent groove side walls are used for For the two receiving groove walls 153 and 154 matched with the corresponding side gaps of the display protection screen, the two positioning groove walls intersect an...

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.
