Jig for case sand blasting of electronic product

Abstract

The invention relates to a jig for case sand blasting of an electronic product and is used for shielding the sand-blasting-free region of a case casing of the electronic product during the sand blasting. The jig comprises an upper plate, a lower plate and a positioning bolt, wherein the positioning bolt can be arranged on the upper plate and the lower plate in a penetrating way and can fix the upper plate and the lower plate, the shape of the upper plate is designed according to the sand-blasting-free region of the casing surface, the upper plate is used for shielding the sand-blasting-free region of the casing surface, when the casing is positioned between the upper plate and the lower plate, the upper plate can be attached to the surface of the casing, and in addition, on the surface with a layer of silica gel surface of the upper plate attached to the casing. The jig has the advantages that the jig with the silica gel surface is used for replacing a silica gel membrane for shielding the sand-blasting-free region of the case of the electronic product, so the sand-blasting region positioning is more accurate, the deformation of the case of the electronic product during the sand blasting is reduced, the casing surface gel residue problem when the silica gel membrane is torn off is avoided, and meanwhile, the problem that sand overflows to the sand-blasting-free region during the sand blasting is also avoided.

Description

technical field [0001] The invention relates to a jig for sandblasting an electronic product casing, which is used for covering the non-sandblasting area of ​​the electronic product casing during sandblasting. Background technique [0002] At present, when the shell (mainly metal shell) of 3C and other electronic products is subjected to surface treatment, sometimes according to the design requirements, it is necessary to perform sandblasting on part of the surface of the shell, so that part of the surface of the shell has a sandy appearance. When sandblasting, the silicone diaphragm is usually pasted on the non-blasting area of ​​the metal shell of the electronic product to play a blocking role, and then the sandblasting gun is used to sandblast the area of ​​the metal shell that needs to be sandblasted. After the sandblasting is completed, Then tear off the silicone membrane. When pasting the silicone diaphragm, you can use a whole piece of silica gel diaphragm to be cut ...

AI Technical Summary

Problems solved by technology

This method of shielding the non-blasting area of ​​the metal shell with a silicone diaphragm has the following disadvantages: 1) The silicone diaphragm is soft, not easy to locate, and prone to displacement or sticking; 2) Pasting process It is manual operation, which increases the labor cost; 3) When the silicone diaphragm is torn off, it is easy to have residual glue in the non-sandblasting area; 4) When the silicone diaphragm is attached to the metal shell, it cannot be completely attached, and it is easy to be sprayed. The problem of spilling sand to the non-blasting area due to the blowing of the sand gun
