Abstract

The utility model relates to a fixture for sand blasting of an electronic product shell. The fixture is used for shielding a non-sand blasting area of the electronic product shell body when performing sand blasting, and comprises an upper plate, a lower plate, and a positioning bolt which can be arranged the upper plate and the lower plate in a penetrating manner to fix the upper plate and the lower plate; the shape of the upper plate is formed according to the non-sand blasting area on the shell surface for shielding the non-sand blasting area of the shell surface; when the shell is positioned between the upper plate and the lower plate, the upper plate can be in fit with the shell surface; and a silicon gel layer is arranged on the upper plate on the surface which is in fit with the shell. The fixture with the silica gel layer is utilized to substitute a silica gel membrane to shield the non-sand blasting area of the electronic product shell, so as to enable positioning of the sand blasting area to be more accurate, reduce the deformation when performing sand blasting to the electronic product shell, avoid adhesive residual problem on the shell surface when ripping out the silica gel membrane, and avoid sand overflow to the non-sand blasting area when performing sand blasting.

Description

Tool is used in a kind of electronic product casing sandblast

Technical field

The utility model relates to a kind of electronic product casing sandblast and uses tool, is used for when sandblast, covering the non-sandblast zone of electronic product casing

Background technology

are present; Electronic product shell such as 3C (mainly being metal shell) add man-hour carrying out surface treatment; Sometimes according to designing requirement, need carry out blasting treatment, make the part surface of shell present the appearance of sand shape the part surface of shell.During sandblast, generally be the non-sandblast zone that sticks on the electronic product metal shell earlier with the silica gel diaphragm, play the effect of blocking, use sand-blasting gun to need the zone of sandblast to carry out sandblast to metal shell then, sandblast tears the silica gel diaphragm off after accomplishing again.When pasting the silica gel diaphragm, can use a bulk silicon glue film to cut out in advance and carry out the integral body stickup, also can use polylith silica gel diaphragm to carry out amalgamation and paste according to the shape in non-sandblast zone according to the shape in non-sandblast zone.This some following drawbacks of method existence of utilizing the silica gel diaphragm that the non-sandblast zone of metal shell is covered: 1) the silica gel diaphragm is softer, is not easy the location, is prone to displacement or pastes inclined to one side phenomenon; 2) taping process is manually-operated, has increased cost of labor; When 3) tearing the silica gel diaphragm off, in non-sandblast zone the cull phenomenon appears easily; When 4) the silica gel diaphragm is attached on the metal shell, can not be adjacent to fully, occur easily being blown afloat and the problem of sand that take place to overflow to non-sandblast zone by sand-blasting gun

Summary of the invention

the utility model technical problem to be solved is the deficiency that overcomes prior art, provides a kind of electronic product casing sandblast to use tool, is used for when sandblast, covering the non-sandblast zone of electronic product casing.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

Tool is used in a kind of electronic product casing sandblast, is used for when sandblast, covering the non-sandblast zone of electronic product casing housing; This tool comprises upper plate, lower plate and can be located on said upper plate and the lower plate and the pilot pin that both are fixed; The shape of upper plate is offered according to the non-sandblast zone of surface of shell, is used for the non-sandblast zone on shielding casing surface; When housing was between upper plate and lower plate, upper plate can paste with the surface of housing mutually, and upper plate with surface that housing pastes mutually on have one deck silica gel layer.

preferably, the material of housing is a metal, further, the material of housing is an aluminium.

preferably, the material of upper plate and lower plate is steel.

Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:

The tool that the utility model utilization has silica gel layer replaces the silica gel diaphragm to cover the non-sandblast zone of electronic product casing; Make the sandblast zone location more accurate; Deflection when having reduced the electronic product casing sandblast; The surperficial cull problem of electronic product casing when having avoided tearing the silica gel diaphragm off, the problem of sand of overflowing when also having avoided sandblast simultaneously to non-sandblast zone.

Embodiment 1

present embodiment provides a kind of notebook computer casing sandblast to use tool.As shown in Figure 3, the shell of present embodiment notebook computer is located at the computor-keyboard part, and dash area is the sandblast zone of housing among the figure, and remainder is non-sandblast zone.

referring to Fig. 1,2 and 4, and the present embodiment tool is used for when sandblast, covering the non-sandblast zone of notebook computer shell housing 5, comprise upper plate 1, lower plate 2 and can be located in upper plate 1 and lower plate 2 on and pilot pin 3 that both are fixed; The shape of upper plate 1 is offered according to the non-sandblast zone on housing 5 surfaces, is used for the non-sandblast zone on shielding casing 5 surfaces; When housing 5 was between upper plate 1 and lower plate 2, upper plate 1 can paste with the surface of housing 5 mutually, and upper plate 1 with surface that housing 5 pastes mutually on have one deck silica gel layer 4 (dash area among Fig. 4).

In present embodiment, lower plate 2 mainly plays a supportive role, and its shape inner surface best and housing 5 is complementary, so that support better.

When the tool of present embodiment is used in ; Be through pilot pin 3 housing 5 to be fixed between upper plate 1 and the lower plate 2 earlier, the silica gel layer 4 of upper plate 1 is adjacent to the non-sandblast zone of housing 5 mutually, and it is more accurate to make housing 5 when sandblast, locate; Be difficult for displacement, the sandblast better effects if.After sandblast finished, only need taken tool apart and get final product, and do not have cull on the housing 5.

according to present embodiment, the material of housing 5 is selected aluminium for use, and the material of upper plate 1 and lower plate 2 is selected steel for use, and the sand that uses during sandblast is glass sand.
