Example 1

The present embodiment provides a positioning fixture, as shown in fig. 1, including: the positioning block 2 is suitable for being detachably attached to the display cover plate 1; and the positioning base 3 is provided with a positioning groove 31 matched with the positioning block 2. When lapping 2 the locating piece on showing apron 1, can fix a position locating piece 2 through the constant head tank 31 of positioning base 3 to indirect the demonstration apron 1 of circular shape is fixed a position, shows apron 1 and passes through locating

piece

2 and 3 spacing backs of positioning base, shows apron 1 and can not take place to remove when carrying out the silk screen printing process again, thereby makes the degree of accuracy of silk screen printing higher. Meanwhile, the circular shape of the display cover plate 1 can be kept, so that the requirement of a user on the shape of the display cover plate 1 is met on the premise of not influencing the function of the display cover plate 1.

In addition to the above-described embodiments, as a further limited embodiment, as shown in fig. 2, the positioning block 2 includes: a bonding surface 22; and the adhesive layer 21 is arranged on the binding surface 22. Glue film 21 can link to each other locating piece 2 and demonstration apron 1 through the mode of adhesion, when fixing spacingly to demonstration apron 1, can not damage demonstration apron 1. And after the display cover plate 1 is processed, the display cover plate 1 can be detached from the display cover plate 1, and the glue layer 21 is not easy to form residues on the display cover plate 1.

Specifically, the surface of the positioning block 2 facing the display cover 1 is a bonding surface 22, the bonding surface 22 may be any shape, and in this embodiment, the bonding surface 22 is rectangular. As an alternative embodiment, the abutting surface 22 may be circular or polygonal. Glue film 21 is attached on binding face 22, and glue film 21 is for pasting the face towards one side of showing apron 1, thereby pastes the face and shows apron 1 contact laminating realization to the location of showing apron 1. Because silk screen printing needs to be carried out on circular display apron 1 to the edge of circular apron needs to carry out the finish machining, consequently the laminating is at the locating piece 2 of display apron 1 bottom, can not form the hindrance to the process of silk screen printing process and edge finish machining.

On the basis of the above-described embodiment, as a further limited embodiment, the positioning block 2 has at least two intersecting positioning surfaces 23, and the intersection line between the positioning surfaces 23 forms at least one edge on the positioning block 2. Can fix a position the locating piece 2 through the locating surface 23 of edge both sides and prescribe a limit to there is the existence of edge, and locating piece 2 can't take place to rotate in constant head tank 31, thereby when fixing a position display cover plate 1, display cover plate 1 can not take place to rotate.

Specifically, in this embodiment, the positioning block 2 is prism-shaped, and has a plurality of positioning surfaces 23 that can provide a fixing base, so as to facilitate the fixing of the positioning block 2. As an alternative embodiment, the positioning block 2 is pyramid-shaped. As another alternative, the positioning block 2 is provided with a positioning hole, or the positioning block 2 is provided with a positioning protrusion.

On the basis of the above embodiment, as a further limited embodiment, the positioning block 2 is a quadrangular prism, and the gap between the positioning block 2 and the positioning groove 31 is not more than 0.1 mm. The assembly of the positioning block 2 is facilitated, and meanwhile, the machining precision of the display cover plate 1 cannot be influenced. The circular cover plate is not easy to rotate and deviate, the positioning precision of the circular cover plate is controlled to be +/-0.2 mm, and the positioning precision of the straight edge 11 of the display cover plate 1 in the prior art can be achieved through the mechanical structure positioning as shown in figure 2. As an alternative embodiment, the gap between the positioning block 2 and the positioning slot 31 is greater than 0.1 mm.

The material of the adhesive layer 21 is not particularly limited, and in this embodiment, the adhesive layer 21 is made of a low temperature removable material. After the display cover plate 1 is processed, the adhesive layer 21 can be removed in a low-temperature environment. The glue layer 21 and the display cover plate 1 are separated under a low temperature environment, and no residue is formed on the display cover plate 1. The low temperature in this embodiment is understood to mean that the ambient temperature is below 10 ℃, and the adhesive layer 21 is in a cured connection state when the ambient temperature exceeds 10 ℃.

The display cover plate 1 of the present embodiment is obtained by rough cutting from a raw material. At this time, the circular accuracy of the display cover plate 1 does not reach the standard, further fine machining is needed, and silk printing is not performed on the display cover plate 1.

Therefore, the roughly cut display cover plate 1 is adhered to the positioning block 2 through the glue layer 21, the positioning block 2 is inserted into the positioning groove 31 on the positioning base 3, and the attaching tolerance between the positioning block 2 and the display cover plate 1 is kept within +/-0.3 mm. At this time, the display cover plate 1 cannot drive the positioning block 2 to rotate in the positioning groove 31, so that the purpose of limiting the display cover plate 1 is achieved. On the other hand, when the positioning block 2 is fitted in the positioning groove 31, a gap is left between the display cover plate 1 and the positioning base 3, so that friction between the display cover plate 1 and the positioning base 3 is prevented.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications can be made without departing from the scope of the invention.
