Abstract
The invention discloses a key substrate supporting jig which is provided with a bulge structure corresponding to a concave cavity at the lower side of a central KEY, wherein the end face and cylindrical body of the bulge structure are transited through a chamfer structure; the end face of the bulge structure and the end face of the concave cavity at the lower side of the central KEY are same in shape and size; and the cross section of the cylindrical body of the bulge structure is greater than that of the cylindrical body of the concave body at the lower side of the central KEY. By utilizing the key substrate supporting jig, the side face of a key substrate, on which excessive printing ink is coated, can exist in an inclined face form during a laser etching process, so that a laser etching jig can conveniently remove the printing ink on the side face, and the product yield is improved.
Description
Technical field
The present invention relates to the production tool of mobile phone key, especially relate to the tool of support key substrate in radium carving process.
Background technology
Mobile phone key is a kind of parts for function control operation on mobile phone, and mobile phone press-key construction is as shown in Figure 1 the one that prior art is common, and its whole flow process of producing shipment is:
1, shaping: to be molded into multiple frame-shaped plastic rubber substrate connected together with rubber mass;
2, print: form prime coat 2 at plastic rubber substrate surface printing ink;
3, the end is sprayed: on prime coat 2, spray ink form outward appearance ink layer 3;
4, spray-coating surface: spray ink and form protection ink layer 4 on outward appearance ink layer 3;
5, die-cut: by diel and pressing equipment, multiple frame-shaped plastic rubber substrate connected together to be punched to single key substrate 1;
6, radium carving: outward appearance ink layer 3 and protection ink layer 4 part hollow out are formed character 5 by radium carving device;
7, PU, packaging, warehouse-in shipment.
In 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 be positioned at same unilateral on, the end face of center KEY key is higher than the end face of common key-press).On existing plastic rubber substrate, the side of stud bump is vertical with endface position, and in print steps, brush runs the surface of ink printing at plastic rubber substrate along the direction parallel with its surface, such stud bump (especially center KEY key) is just inevitably printed with ink towards the side of brush traffic direction, in order to ensure the quality of final products, in radium carving step, except forming character 5, also will by the excess ink of stud bump side to getting rid of, during radium carving, need first button base 1 material to be placed on support tool, existing support jig structure, as Fig. 2, shown in Fig. 3, be groove protruding on the downside of corresponding common key-press or engraved structure 7 in the place of corresponding common key-press, at the bulge-structure 6 that the place of corresponding center KEY key is cavity on the downside of the KEY key of corresponding center, on the downside of the end face of bulge-structure 6 and columnar part and center KEY key cavity end face and and columnar part structure, size is almost identical, during concrete placing key-press base material 1, on the downside of common key-press, protruding respective slot or engraved structure 7 are placed, center KEY key is enclosed within bulge-structure 6, such support tool mainly plays a setting to button base 1, key substrate 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 excess ink of the stud bump side parallel with its direction is removed.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of radium carving tool of mobile phone key, can effectively remove the ink that the vertical side of mobile phone key is printed to.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of support tool of key substrate, which is provided with the bulge-structure of cavity on the downside of the KEY key of corresponding center, by chamfering structure transition between the end face of described bulge-structure and cylinder, and the end surface shape of cavity is measure-alike on the downside of the end face of bulge-structure and center KEY key, the cylinder cross section of bulge-structure is larger than the cylinder cross sectional dimensions of cavity on the downside of the KEY key of center.
The support tool of comparing traditional, the columnar part physical dimension of its bulge-structure becomes large, and this is due to the generation of transition chamfering structure; During use, be enclosed within this bulge-structure by the center KEY key of key substrate, due to the pliability of key substrate, its side is along can along the slope enlargement deformation of chamfering structure, and keep end indeformable; The side being printed with excess ink so is just launched along slope, is convenient to radium carving tool and carries out work to it, to get rid of unnecessary ink; After radium has been carved, take off key substrate, it can resile, and is unlikely to cause bad.Certainly, the size of chamfering needs the height being coated with excess ink according to side to determine.
This support tool is also provided with groove protruding on the downside of corresponding common key-press or engraved structure; Be convenient to other buttons beyond centre of location KEY key.
Beneficial effect: the support tool of key substrate provided by the invention, key substrate is made to carry out in radium carving process, the side being coated with excess ink can occur with the situation of slope, is convenient to radium carving tool to the removal of its curing ink, adds the yield of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing mobile phone key;
Fig. 2 is the front view of existing support tool;
Fig. 3 be in Fig. 2 A-A to cutaway view;
Fig. 4 is front view of the present invention;
Fig. 5 be in Fig. 4 A-A to cutaway view.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
Be a kind of support tool of key substrate as shown in Figure 4, Figure 5, which is provided with groove protruding on the downside of the bulge-structure 6 of cavity on the downside of the KEY key of corresponding center and corresponding common key-press or engraved structure 7, by chamfering structure transition between the end face of described bulge-structure 6 and cylinder, and the end surface shape of cavity is measure-alike on the downside of the end face of bulge-structure 6 and center KEY key, the cylinder cross section of bulge-structure 6 is larger than the cylinder cross sectional dimensions of cavity on the downside of the KEY key of center.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
Claims (2)
1. the support tool of a key substrate, which is provided with the bulge-structure (6) of cavity on the downside of the KEY key of corresponding center, it is characterized in that: by chamfering structure transition between the end face of described bulge-structure (6) and cylinder, and the end surface shape of cavity is measure-alike on the downside of the end face of bulge-structure (6) and center KEY key, the cylinder cross section of bulge-structure (6) is larger than the cylinder cross sectional dimensions of cavity on the downside of the KEY key of center.
