Description

The computer keyboard film that has projection

Technical field

The utility model relates to the input equipment production technical field, relates to a kind of computer keyboard film that has projection in particular.

Background technology

In the keyboard production run, generally adopt the part that on film, needs light leak to paste other materials such as light trap, foam at present, light is appeared the particular bore on lampshade or foam reach the effect of building up light, the bright lamp of keycap.Tradition silica gel lampshade is to adopt silica gel material to be made by moulding, and because of its planform relative complex, and mould and die accuracy requirement itself is very high, so mechanism's shape and size precision just is difficult to control, die cost is also very high; The size of material such as lampshade, foam own is less, and is not easy to operate when producing with film applying, must paste time-consuming taking a lot of work; Silica gel, foam material material is softer elasticity preferably again, is difficult to accomplish precisely on the location, so easily produce offset when producing; With little burr, light has shadow after aperture transmits, influence light intensity and transparency range when making at light hole edge on the lampshade, and behind the assemblying keyboard because of itself material elasticity feel of factor affecting keyboard preferably itself.It is more that this type of technology is produced the consumption material at present, and production run is longer, and precision is difficult to control, and cost is also very high, and the production timeliness is lower.

The utility model content

In order to solve the problem of above-mentioned existence, the purpose of this utility model is to provide a kind of computer keyboard film that has projection, adopt desired shapes to replace traditional lampshade, foam to cover accumulation light, realize the aesthetic property of keyboard overall appearance, to shorten production run, promote the production timeliness, reduce and produce fraction defective, production cost is descended.

To achieve these goals, the utility model is by the following technical solutions:

Have the computer keyboard film of projection, the top of described projection has light hole.

Preferably, described projection top or below post the shading film material.

Computer keyboard film of the present utility model, having replaced other materials such as traditional dependence stickup lampshade, foam comes collected light, shield lights and stablizes the light scope, beautify the bright lamp effect of keyboard and strengthened light texture, cancelled the consumption of lampshade, foam material in process of production, cancelled the production process in early stage of traditional lampshade, foam, save the operation of pasting of traditional lampshade, foam, shortened procedure for producing, promoted the production timeliness, reduced the production fraction defective, production cost is declined to a great extent.

Embodiment

Below in conjunction with drawings and the specific embodiments the utility model is made further description explanation.

Embodiment as shown in Figure 1, a kind of computer keyboard film that has projection, top in projection 101 has light hole 102, light orientation from light hole 102 appears, the direct projection keyboard cover, realize collected light, shield lights, stablize the light scope in order to replace other materials such as traditional stickup lampshade, foam, and beautified the bright lamp effect of keyboard and strengthened light texture, the projection 101 above or below post shading film material 103, with the appearance property that prevents that the light large tracts of land from appearing influences spotlight effect, light intensity and the bright lamp of keyboard.

A kind of computer keyboard comprises the steps: with the protruding moulding process of film self

At first, according to needing the material of moulding, protruding 101 shapes and size to design the parameter of protruding mould and definite mould key position;

Secondly, use protruding mould that the material that needs moulding is carried out protruding forming processes;

At last, adopt special punching die punching out light hole 102 at its top after protruding moulding is finished, the position of light hole 102 is corresponding with the keyboard center.

As shown in Figure 2, when carrying out protruding forming processes, the protruding mould that adopts comprises two relative die holders 201, the relative inner of two die holders 201 respectively is provided with one deck thermal insulation board 202, can prevent the loss of the heat in the mould, energy savings consumes, save production cost, thermal insulation board 202 tops that are positioned at protruding mould bottom are provided with punch clamping plate 203, thermal insulation board 202 belows that are positioned at protruding mould top are provided with die clamping plate 204, the two ends of punch clamping plate 203 respectively are provided with a guide pillar 205, be provided with punch 209 between two guide pillars 205, the two ends of die clamping plate 204 respectively are provided with a guide pin bushing 206, be provided with die 207 between two guide pin bushings 206, on punch clamping plate 203 and die clamping plate 204, be equipped with heat hole 208 and temperature detection hole 210, punch 209 and die 207 are the structural design of coincideing mutually, it is the key in the molding procedure, the below of die clamping plate 204 is provided with stripper plate 211, be provided with two springs 212 between stripper plate 211 and the punch clamping plate 203, spring 212 is fixed on the punch clamping plate 203, lay respectively near the inboard of two guide pillars 205, the setting of spring 212 is for convenience of when carrying out forming processes, can control easily and regulate in the forming process the moulding material applied pressure.

In the middle of the process of forming processes, adopt the adjustable speed-changing punch press.Protruding forming process as shown in Figure 3, in draw stage, to needing the certain pressure of applying of moulding material, make the even stressed after stretching moulding of the material that needs moulding, along with the intensification that coincide between punch 209 and the die 207, deformation owing to take place in the spring 212 between stripper plate 211 and the punch clamping plate 203, the elastic force that produces will be increasing, punch press speed will be slack-off gradually, when elastic force increases to identical with pressure the time, will produce required projection 101, in the forming process material that needs moulding is adopted the method for spot heating, temperature as required moulding material difference and determine, and take independent control; Still need after the material production projection 101 projection 101 is kept certain pressure, and certain time, make projection stablize moulding.

The utility model can replace traditional dependence to paste the design that lampshade and foam are built up keyboard light, because projection 101 is the projectioies 101 that go out certain altitude and shape from the straight forming of film own, paste lampshade and the foam raised position is better controlled with respect to tradition; Can select harder and on-deformable material for use because of itself material again, so the bossing after the moulding is not yielding; And because of the harder and inelastic characteristic of itself material, adopt mould stamping-out light hole 102, not only make easily, timeliness is good, shape is controlled easily, and the light hole edge does not have burr, lousiness, it is all fixing that light therefrom appears back shape, intensity and scope, the light position stability, the bright lamp intensity of keycap unanimity, indifference behind the assemblying keyboard, keyboard appearance is more attractive in appearance; And because of its projection back shape and nonelastic itself, so do not influence the performance and the feel of keyboard itself.Cancel the consumption of lampshade, foam material in process of production, cancelled the production process in early stage of traditional lampshade, foam, save the operation of pasting of traditional lampshade, foam, shortened procedure for producing, promoted the production timeliness, reduced the production fraction defective, production cost is declined to a great extent.
