Description

Sputtering shielding jig for notebook shell

Technical Field

The utility model relates to a sputtering shields the tool field, in particular to notebook shell sputtering shields tool.

Background

The process of magnetron sputtering plating of electromagnetic interference resistant film (EMI resistant film for short) on notebook computer casing is widely adopted due to the advantages of good electromagnetic shielding effect, long service life, thin film layer and the like. In order to achieve the designed sputtering area and non-sputtering area, a tool fixture can be used to expose the area to be sputtered in the sputtering process, and the insulating area is shielded to realize the purpose. Consider that the temperature rise in the sputtering process can lead to plastic shell (the material is mostly PC + ABS) to have certain deformation, and current tool is upper and lower cover lock, the lower cover is a horizontal plane, the normal lock in upper cover press down the lid plane, but the plastic product has certain radian, because the radian that can lead to the plastic product after upper cover and lower cover lock flatten fixedly, consequently through the fixed operation that flattens of sputtering thermal deformation and tool, the product after can causing the sputtering surpasss design direction and scope.

Therefore, it is necessary to provide a sputtering shielding fixture for notebook computer housing to solve the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a notebook shell sputtering shields tool can reduce because the tool shields the product condition of scrapping that the too big production of deformation that the problem of die cavity shape leads to under the prerequisite that does not influence the effect of shielding to the sputtering yield has been improved greatly.

The utility model provides a technical scheme that its technical problem adopted is: a sputtering shielding jig for a notebook shell comprises a lower jig cover provided with a lower sputtering cavity and an upper jig cover provided with an upper sputtering cavity, wherein the upper sputtering cavity and the lower sputtering cavity are combined to form a sputtering cavity for placing a product;

the lower fixture cover is also provided with a limiting column and a plurality of guide columns, the lower sputtering cavity comprises a lower cover plane and a plurality of lower cover curved surfaces, and the lower cover curved surfaces are respectively arranged on the periphery of the lower cover plane;

the fixture upper cover is further provided with a limiting hole and a plurality of guide holes, the upper sputtering cavity comprises an upper cover plane and a plurality of upper cover curved surfaces, and the upper cover curved surfaces are respectively arranged on the periphery of the upper cover sheet surface.

Specifically, the guide posts are arranged at four corners of the lower cover of the jig.

Specifically, the guiding holes are arranged in four corners of the upper cover of the jig.

Specifically, the limiting columns correspond to the limiting holes, and the guide columns correspond to the guide holes.

Specifically, radian and concave-convex conditions can be adjusted according to the requirements of products by the upper cover curved surface and the lower cover curved surface.

The utility model relates to a fixture is shielded in sputtering of notebook shell's beneficial effect is, through the cooperation of fixture lower cover and fixture upper cover, can guarantee the fixed effect of product, through the cooperation of upper cover curved surface and case lid curved surface, can reduce because the fixture shields the product condition of scrapping that the product deformation that the problem of die cavity shape leads to is too big to produce under the prerequisite that does not influence the effect of shielding to the sputtering yield has been improved greatly.

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural view of a lower cover of a sputtering shielding jig for a notebook shell of the present invention;

FIG. 2 is a schematic structural view of an upper cover of the sputtering shielding jig for notebook computer housings;

in the figure: 1. the jig comprises a jig lower cover, 2 parts of guide posts, 3 parts of limiting posts, 4 parts of a lower cover plane, 5 parts of a lower cover curved surface, 6 parts of a jig upper cover, 7 parts of guide holes, 8 parts of an upper cover plane and 9 parts of an upper cover curved surface.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

As shown in fig. 1-2, a sputtering shielding jig for a notebook shell comprises a lower jig cover 1 provided with a lower sputtering chamber and an upper jig cover 6 provided with an upper sputtering chamber, wherein the upper sputtering chamber and the lower sputtering chamber are combined to form a sputtering cavity for placing a product;

the lower fixture cover 1 is also provided with a limiting column 3 and a plurality of guide columns 2, the lower sputtering cavity comprises a lower cover plane 4 and a plurality of lower cover curved surfaces 5, and the lower cover curved surfaces 5 are respectively arranged on the periphery of the lower cover plane 4;

the fixture upper cover 6 is further provided with a limiting hole and a plurality of guide holes 7, the upper sputtering cavity comprises an upper cover plane 8 and a plurality of upper cover curved surfaces 9, and the upper cover curved surfaces 9 are respectively arranged on the periphery of the upper cover surface.

Specifically, the guide posts 2 are arranged at four corners of the jig lower cover 1.
