Description

3D4R cell phone case tool

Technical Field

The utility model relates to a cell-phone shell processing equipment technical field, concretely relates to 3D4R cell phone case tool.

Background

The mobile phone protection shell not only serves as an ornament to improve the attractiveness of the mobile phone, but also can protect the mobile phone, and has the functions of falling prevention, scraping prevention, water prevention and shock prevention. Along with the renewal of cell-phone shell product, various three-dimensional (3D) cell-phone shell has appeared on the market, four sides of cell-phone shell and four corners all have the R angle structure (be approximate to 1/4 circular arc flange structure promptly, collectively refer to 4R), this type of cell-phone shell (3D 4R cell phone case promptly) can realize the all-round parcel to the cell-phone, again can with the seamless laminating of cell-phone, protection and pleasing to the eye effect are outstanding, have received more and more consumers' liking.

When the mobile phone shell is produced, a plastic semi-finished product is formed by a mould, and then a photosensitive film is coated on the surface of the semi-finished product by adopting a vacuum film coating technology. And to the cell-phone shell of 3D4R type, when using traditional tool to carry out the vacuum tectorial membrane, the diaphragm is directly taken on cell-phone shell R angle structure, and the diaphragm can be followed the cell-phone shell outside and pasted to the centre gradually all around after the evacuation and is covered, because the existence at R angle this moment, the cell-phone shell is inside can form inclosed cavity, leads to the diaphragm can't continue closely to paste with the cell-phone shell internal surface and cover, a large amount of bubbles appear finally, especially the unable subsides of R angle internal surface cover at all. Therefore, the jig used for vacuum lamination needs to be improved to meet the vacuum lamination process of the 3D4R type mobile phone shell.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a 3D4R cell phone case tool, it has solved traditional cell-phone shell tool and has appeared the problem of the unable tectorial membrane of a large amount of bubbles and R angular position easily when carrying out the vacuum tectorial membrane to the cell-phone shell of 3D4R type.

The utility model discloses a following technical scheme realizes above-mentioned purpose:

the utility model provides a 3D4R cell phone case tool, includes the tool body, open on the upper portion of tool body has the work piece groove that is used for placing cell phone case, the work piece inslot is opened has a plurality of gas pockets, still including the apron that is used for holding the diaphragm material, open at the middle part of apron has the opening, makes the apron form the circle structure, and when the apron lid on tool body upper portion, the vertical projection of apron inner circle covers the up end of cell phone case R angle structure at least, and the apron inner circle lower lip edge and leave the clearance between the structural up end of cell phone case R angle.

The further improvement is that the cover plate inner ring extends to the middle relative to the upper end surface of the R angle structure of the mobile phone shell by 0.2-0.8 cm.

The further improvement is that the gap width is 0.1-0.5 cm.

The further improvement lies in that the cover plate and the jig body are split.

The improved structure is characterized in that the lower part of the cover plate is provided with a trapezoidal groove, the upper part of the jig body is provided with a convex edge matched with the trapezoidal groove, and when the cover plate covers the upper part of the jig body, the convex edge is just embedded in the trapezoidal groove to realize the positioning of the cover plate.

The further improvement is that the upper part of the cover plate is covered with an anti-sticking cloth layer.

The beneficial effects of the utility model reside in that: this tectorial membrane tool has add the apron structure, through this ingenious institutional advancement for the diaphragm laminating mode changes into and laminates gradually by middle toward all around, has avoided the phenomenon of bubble to appear in tectorial membrane back cell-phone shell internal surface from this, has especially guaranteed the tight laminating of cell-phone shell R angle department, has really realized the vacuum tectorial membrane technology of 3D4R cell-phone shell.

in the figure: 1. a jig body; 2. a workpiece groove; 3. air holes; 4. a cover plate; 5. a port; 6. a trapezoidal groove; 7. a convex edge; 8. an anti-sticking cloth layer; 9. an R-angle structure; 10. an upper end surface; 11. a membrane.

Detailed Description

The present application will now be described in further detail with reference to the drawings, it should be noted that the following detailed description is given for illustrative purposes only and is not to be construed as limiting the scope of the present application, as those skilled in the art will be able to make numerous insubstantial modifications and adaptations to the present application based on the above disclosure.

Referring to fig. 1 to 3, a 3D4R mobile phone case fixture comprises a fixture body 1, a workpiece groove 2 for placing a mobile phone case is formed in the upper portion of the fixture body 1, a plurality of air holes 3 are formed in the workpiece groove 2, the air holes 3 are vertically through, when air is pumped from the lower portion of the fixture body 1, the air can be pumped into the workpiece groove 2 through the air holes 3, and the bottom of the workpiece groove 2 is of a rough design, so that the air pumping process is not affected after the mobile phone case is placed; the jig further comprises a cover plate 4 used for supporting the film materials, a through hole 5 is formed in the middle of the cover plate 4, the cover plate 4 is made to form a ring-shaped structure, when the cover plate 4 covers the upper portion of the jig body 1, the vertical projection of the inner ring of the cover plate 4 at least covers the upper end face 10 of the R-shaped structure 9 of the mobile phone shell, and a gap is reserved between the lower opening edge of the inner ring of the cover plate 4 and the upper end face 10 of the R-shaped structure 9 of the mobile phone shell. Specifically, the inner ring of the cover plate 4 extends to the middle by 0.2-0.8cm relative to the upper end face 10 of the corner structure of the mobile phone shell R, namely h2 in fig. 3; the gap width is 0.1-0.5cm, h1 in fig. 3.

The utility model discloses in, apron 4 is split type with tool body 1, and open the lower part of apron 4 has dovetail groove 6, and the upper portion of tool body 1 is formed with 6 assorted chimbs 7 of dovetail groove, when apron 4 lid on 1 upper portion of tool body, chimbs 7 inlays just in dovetail groove 6, realizes apron 4's accurate positioning.

In particular, the upper part of the cover plate 4 is covered with an anti-sticking cloth layer 8 for preventing the membrane material from sticking on the cover plate 4 and ensuring the smooth operation of the film covering.

The jig aims at the vacuum film coating work of the mobile phone shell with the R-angle structure 9, and when the jig is used, the jig body 1 is firstly placed on a corresponding vacuumizing platform so as to exhaust air from the bottom of the jig body 1; then, the mobile phone shell is placed at the right middle position of the workpiece groove 2, and the R angle structure 9 is upward; then the cover plate 4 is covered on the upper part of the jig body 1, and the air tightness of the contact surface is ensured after the cover plate is covered; then, the photosensitive film 11 is placed on the cover plate 4, the periphery of the film 11 is compacted, and the film 11 seals the whole opening 5 of the cover plate 4; make it soften after heating diaphragm 11 certain degree, can carry out the evacuation to the lower part of tool body 1 this moment, the air between diaphragm 11 and the cell-phone shell is taken out through the clearance position between 4 inner circle lower limb of apron and cell phone case R angle structure 9 up end 10, and discharge from the gas pocket 3 of bottom, make inside atmospheric pressure reduce gradually, thereby make diaphragm 11 laminate down gradually, and the laminating mode is around after the centre earlier, cell phone case's R angle structure 9 just can contact the laminating with diaphragm 11 at last, cell phone case's internal surface has all accomplished the tectorial membrane before the contact, can guarantee not to appear any bubble like this, and last R angle structure 9 also can be wrapped up by diaphragm 11 strictly, really realize 3D4R cell phone case's whole tectorial membrane.
