Jig

Abstract

The invention relates to a jig. After a product is installed on the installation position, a first area can be covered through the matching effect of a cover plate and a shielding piece, and after sand blasting operation is executed, due to the fact that a second area is exposed, the sand effect of the second area can be different from that of the first area. After the product is covered with the cover plate, a first edge protrudes out of the cover plate, so that the first edge can abut against the boundary when coinciding with the boundary between the first area and the second area, and therefore in the sand blasting operation process, due to blocking of the first edge, blasting materials cannot cross the boundary and enter the first area; and therefore, a clear sand effect boundary is formed between the first area and the second area. Besides, sand blasting operation can be performed only by locking the product on the jig, and the product can be taken down after the operation is finished, so that the operation is simple and convenient. The jig is not easy to damage and can be repeatedly used, so that the consumable consumption cost of film pasting or printing ink is saved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of surface processing of electronic products, in particular to a jig. Background technique [0002] In the surface processing process of the back shell of mobile phones, tablets, notebooks and other electronic products, in order to make the back shell present a variety of sandblasting effects and present a clear dividing line between two adjacent sand effect areas, the conventional operation method It is to use the method of sticking film or exposure, development and masking to cover one area and expose the other area, and then sandblast the exposed area, so that the two areas show different sand effects. [0003] However, the above-mentioned operation methods will cause a large loss of consumables such as film or ink, and high production costs, and whether it is film or ink coating, the operation will be more complicated, and the boundary line is prone to blurring, so that it is impossible to obtain Clear ...
