Abstract
A method for manufacturing a keystroke panel including a smooth surface, a misty surface or a grain layer is disclosed, comprising the steps of: at first, manufacturing a module whose inside bottom surface is coarse surface, smooth surface or grain surface, dropping colloid into the module and covering a carrier on the surface of the colloid, using idler wheels to roll and press on the surface of the carrier so that the carrier and the colloid are flat within the module; then irradiating with ultraviolet light in order that the colloid is hardened to form a keystroke layer attached to the carrier, afterwards, on the carrier, sequentially film-forming a bottom colour layer, functional colour layer and font colour layer as the background of the keystroke panel. Finally, hot-pressing the formed keystroke layer and the silica gel to combine both, namely, the manufacturing of keystroke panel is finished.
Description
Technical field
The present invention relates to a kind of press-key structure, relate in particular to a kind of manufacture method of structure of thin-formed push button key.
Background technology
Ordinary consumer is when choosing mobile phone, and except the function of considering mobile phone, most important is exactly that whether enough whether the face shaping of mobile phone novel and volume reach little.Therefore, some mobile phone can print colored drawing pattern on housing or button, or directly solid grain is made on this housing, with the surcharge of increase product and consumer's desire to purchase.
Referring to Figure 1A, traditional solid grain is made, be on base material 1a, to adhere to the first hyaline layer 2a, on the first hyaline layer 2a, adhere to the first color layers 3a and color open region 31a, adhere to the second hyaline layer 4a on the first color layers 3a, adhere to the second color layers 5a in the second hyaline layer 4a again, with aforesaid display structure form, make the surface of product produce the color of the different depth of field of tool and the outward appearance of lines, with demand as different visual appearances or function.But this manufacture method is too consuming time, take a lot of work, and easily causes the increase of production cost.
Another kind of manufacture method is that lines is made in the press-key structure, referring to Figure 1B, lines layer 1b is located between this thin layer 2b and the elastic layer 3b, dazzles light effect with generation.Because this scheme is located at thin layer 2b and elastic layer 3b between the two with lines layer 1b, step of not only making on making or program increase, and man-hour also increase relatively, also cause the increase of button thickness on the other hand, be a kind of ideal designs not to the utmost for the thickness of thin shape push button.
Summary of the invention
Therefore, the invention provides a kind ofly when button is made in mould, direct forming shiny surface, cloudy surface or lines layer on key panel or keytop not only can not cause the increase in production process, man-hour, also can not cause the increase of press-key structure thickness.
For achieving the above object, has a shiny surface according to of the present invention, the manufacture method of the thin shape push button of cloudy surface or lines layer key panel, comprising the steps: to prepare inner bottom surface is matsurface, the mould of shiny surface or lines face, colloid is clicked and entered in mould, and cover carrier on colloid, utilize roller that carrier and colloid roll extrusion are flattened in mould, mould is carried out UV-irradiation, making the colloid sclerosis form key layer is attached on the carrier, then, film forming background color layer on carrier, the literal of shaping Openworks shape on the while background color layer, the pattern of digital or various symbols, film forming function color layers on the background color laminar surface, again in the background color layer, film forming font color layer on the function color layers surface, key layer after will being shaped again and silica gel are placed in another mould to carry out hot pressing key layer is combined with silica gel, makes silica gel form elastic layer, promptly finishes key panel and makes.
Manufacture method according to thin shape push button provided by the invention, because when button is also made in mould, just direct forming shiny surface, cloudy surface or lines layer on key panel or keytop, not only can not cause the increase in production process, man-hour, nor can cause the increase of press-key structure thickness.
