In this embodiment, the fixture body 10 is made of bakelite, and in other embodiments, it may be made of metal, plastic, or ceramic. In addition, in the present embodiment, the jig main body 10 is provided in a disc-shaped structure, and in other embodiments, the jig main body 10 may have other shapes, for example, a rectangular plate shape, a strip plate shape, and the like.
As shown in fig. 2 and 3, the bearing surface of the jig body 10 is provided with a contour groove 11. The contoured groove 11 is contoured to the contour of the non-swept area of the glass 200. The curved groove 11 is used for accommodating the glass 200 and a non-scanning area of the glass 200, and the scanning area of the glass 200 extends out of the curved groove 11.
The shape of the groove 11 depends on the shape of the glass 200 to be scanned. For example, in the present embodiment, the glass 200 to be scanned is an arc-shaped glass sheet (e.g., a glass screen on a smart band), and accordingly, in the present embodiment, the curved groove 11 is an arc-shaped groove.
Considering that the jig is loaded, if the size of the contour groove 11 is completely consistent with the size of the glass 200, it will be difficult to put the glass 200 into the contour groove 11. Therefore, in the present embodiment, the inner side wall of the contour groove 11 is expanded by 0.05 ± 0.01mm to the outer side of the glass 200. In order to put the glass 200 into the contour groove 11, the inner side wall of the contour groove 11 is provided with a single side which is enlarged by 0.05 +/-0.01 mm, and the feeding difficulty of the jig is reduced on the premise of ensuring the positioning stability of the glass 200.
In order to improve the light sweeping efficiency, the number of the contour grooves 11 may be multiple, and the plurality of contour grooves 11 are distributed on the bearing surface of the jig body 10 in an array. The plurality of profile grooves 11 distributed in the array enable the jig to load the glass 200 in batches, and the light scanning efficiency of the glass 200 is improved. As shown in fig. 1, in the present embodiment, 35 contour grooves 11 are distributed on the carrying surface of the fixture body 10 in an array manner, and 35 pieces of glass 200 can be carried in one scanning operation.

For example, in other embodiments, the jig body 10 may include: the positioning module comprises a base and a positioning module detachably mounted on the base. The profile groove 11 is arranged on the positioning module. According to different glass 200, can change different orientation module, improve the use flexibility of tool.
Further, the positioning module can be connected with the base through clamping, embedding, screw connection or other detachable connection modes.
In the glass light-scanning jig 100, the bearing surface of the jig body 10 is provided with the contour groove 11, as shown in fig. 4 to 6, before the glass 200 is scanned, the glass 200 is placed in the contour groove 11, and the surface of the glass 200 which needs to be scanned faces upward, so that the light-scanning area of the glass 200 extends out of the contour groove 11, and the non-light-scanning area of the glass 200 is buried in the contour groove 11. Since the curved groove 11 is formed according to the shape of the glass 200, the outer contour of the glass 200 can be closely attached to the inner wall of the curved groove 11. The position of the glass 200 is limited by the inner side wall of the profiling groove 11, so that the glass 200 cannot shake or deflect randomly, a good positioning effect is achieved, the light scanning precision is improved, and the risk of deformation of the glass 200 after light scanning is reduced. Through the design, the jig body 10 is provided with the profile modeling groove 11 for accommodating the glass 200, and the concave position of the profile modeling groove 11 is used for limiting the glass 200, so that a good positioning effect is achieved, and the risk of deformation of the glass 200 after scanning is reduced.
