Abstract

The utility model discloses a support fixture for a key base material and the support fixture is provided with a convex structure corresponding to a concave cavity on a lower side of a central KEY key. An end face of the convex structure transits to a cylinder by a chamfering structure. The shapes and sizes of the end face of the convex structure and an end face of the concave cavity on the lower side of the central KEY key are the same. The size of a cross section of the cylinder of the convex structure is larger than that of the concave cavity on the lower side of the central KEY key. According to the support fixture for the key base material provided by the utility model, a side surface coated superabundant ink can show as an incline manner in a laser engraving process of the key base material, thereby being convenient for removing ink on the laser engraving fixture and increasing product yield rate.

Description

A kind of support tool of button base material

Technical field

The utility model relates to the production tool of mobile phone key, especially relates to the tool of support button base material in the radium carving process.

Background technology

Mobile phone key is a kind of parts that are used for the function control operation on the mobile phone, and mobile phone press-key construction as shown in Figure 1 is common a kind of of prior art, and its whole flow process of producing shipment is:

1, moulding: be molded into a plurality of frame shape plastic rubber substrates that connect together with rubber mass;

2, printing: form prime coat 2 at plastic rubber substrate surface printing printing ink;

3, the spraying end: spraying printing ink forms outward appearance ink lay 3 on prime coat 2;

4, spraying face: spraying printing ink forms protection ink lay 4 on outward appearance ink lay 3;

5, it is die-cut: through diel and pressing equipment, a plurality of frame shape plastic rubber substrates that connect together are punched to single button base material 1;

6, radium carving: outward appearance ink lay 3 and protection ink lay 4 part hollow outs are formed character 5 through radium carving device;

7, PU, packing, warehouse-in shipment.

In the above-mentioned steps, the surface of plastic rubber substrate be the end face of stud bump (comprise center KEY key and other common key-press, the end face of general common key-press is positioned at same unilateral on, the end face of center KEY key will be higher than the end face of common key-press).On the existing plastic rubber substrate, the side of stud bump is vertical with endface position, and in the print steps, brush edge and its parallel direction operation in surface are with the surface of ink printing at plastic rubber substrate; Stud bump (especially center KEY key) just inevitably is printed printing ink towards the side of brush traffic direction like this; In order to guarantee the quality of final products, in radium carving step, except forming character 5, also to the unnecessary printing ink of stud bump side be got rid of; During the radium carving; Need at first button base 1 material to be placed on the support tool, existing support jig structure is like Fig. 2, shown in Figure 3; In the place of corresponding common key-press is protruding groove or engraved structure 7 of corresponding common key-press downside; The place of KEY key is the bulge-structure 6 of corresponding center KEY key downside cavity at corresponding center, the end face of the end face of bulge-structure 6 and cylinder part and center KEY key downside cavity and with trunk portion separation structure, size much at one, when specifically placing button base material 1; Protruding respective slot of common key-press downside or engraved structure 7 are placed; Center KEY key is enclosed within on the bulge-structure 6, and the support tool mainly plays a setting to button base 1 like this, and button base material 1 can not produce distortion in shape; And present radium carving direction is generally perpendicular to the surface of plastic rubber substrate, is difficult to or very effectively the unnecessary printing ink of the stud bump side parallel with its direction is removed.

The utility model content

Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides a kind of radium carving tool of mobile phone key, can effectively remove the printing ink that is printed on the vertical side of mobile phone key.

Technical scheme: for solving the problems of the technologies described above, the technical scheme that the utility model adopts is:

A kind of support tool of button base material; Which is provided with the bulge-structure of corresponding center KEY key downside cavity; Pass through the chamfering structure transition between the end face of said bulge-structure and the cylinder; And the end surface shape of the end face of bulge-structure and center KEY key downside cavity is measure-alike, and the cylinder cross section of bulge-structure is bigger than the cylinder cross sectional dimensions of center KEY key downside cavity.

The support tool of comparing traditional, the trunk portion separation structure size of its bulge-structure become big, and this is owing to the transition chamfering structure produces; During use, the center KEY key of button base material is enclosed within on this bulge-structure, since the pliability of button base material, the slope enlargement deformation of its side along meeting along chamfering structure, and keep the end indeformable; Just launch along slope the side that is printed unnecessary printing ink like this, is convenient to radium carving tool it is carried out work, to get rid of unnecessary printing ink; After the radium carving is accomplished, take off the button base material, it can resile, and is unlikely to cause bad.Certainly, the size of chamfering need be confirmed according to the height that the side is coated with unnecessary printing ink.

Also be provided with corresponding common key-press downside protruding groove or engraved structure on this support tool; Be convenient to other buttons beyond the centre of location KEY key.

Beneficial effect: the support tool of the button base material that the utility model provides; Make the button base material in carrying out radium carving process; The side that is coated unnecessary printing ink can occur with the situation of slope, is convenient to the removal of radium carving tool to printing ink on it, has increased the yield of product.

Embodiment

Below in conjunction with accompanying drawing the utility model is done explanation further.

As Fig. 4, shown in Figure 5 be a kind of support tool of button base material; Which is provided with the bulge-structure 6 and protruding groove or the engraved structure 7 of corresponding common key-press downside of corresponding center KEY key downside cavity; Pass through the chamfering structure transition between the end face of said bulge-structure 6 and the cylinder; And the end surface shape of the end face of bulge-structure 6 and center KEY key downside cavity is measure-alike, and the cylinder cross section of bulge-structure 6 is bigger than the cylinder cross sectional dimensions of center KEY key downside cavity.

The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
