Description
Technical field
The utility model relates to optical keyboard field, is specifically related to a kind of shading condensing film structure for optical keyboard.
Background technology
At present, optical keyboard require glossiness and cleanliness factor higher, process-intensive, need through ink printing-cross cutting processing-glue printing-punch forming-optical detection, and can complete, therefore yield is lower, and personnel's technique is more, and quality is difficult to management and control.Because the button on keyboard is more, between keyboard, space is less, play shading and spotlight effect just can form keyboard surrounding flash effect, must use reflector plate.
If reflector plate is put into separately on the circuit board below button, role is very faint, cannot reach the effect of optically focused flash of light.Therefore, the product being applicable to optical keyboard designing a kind of optically focused good shading effect is needed.
Utility model content
For solving the problems of the technologies described above, the utility model proposes a kind of shading condensing film structure for optical keyboard, it is single that the application of this product can improve existing reflector plate structure significantly, perfectly cannot realize the object of effect of optically focused, shading.
For achieving the above object, the technical solution of the utility model is as follows:
For a shading condensing film structure for optical keyboard, comprise PET protection film from top to bottom successively, reflector plate that thickness is 0.02-0.03mm and blue release film; Wherein, the lower surface edge of described reflector plate is provided with the continuous glue district that a circle width is 5-10mm, and the upper surface of described reflector plate is coated with black ink, and is provided with a circle glue point near the inner ring position in continuous glue district; Overhanging pulling portion is provided with on the left of described PET protection film.
Preferably, light guide plate is provided with between described PET protection film and described reflector plate.
Preferably, described reflector plate thickness is 0.023mm, described blue release film thickness 0.075mm, described black ink thickness 0.007mm, PET protection film 0.05mm.
Preferably, the thickness of described continuous glue district and described glue point is 0.02-0.04mm.
PET protection film and white reflective sheet fit together, and centre adds that the black ink of certain glossiness carries out light source shielding effect, and reflector plate another side carries out the printing of fixing point glue, plays and uses with keyboard sticker cooperation.
PET protection film thickness 0.05mm, carries out protection ink on surface, plays a very good protection when running into high temperature and friction.Glue is 3M import glue, and thickness 0.03mm plays product and plastic cement keyboard connection function.Reflector plate is imported material, thereon printing-ink, well can protect the glossiness of ink.Blue release film, thickness 0.075mm, carries out the release effect of glue overleaf, conveniently gets and paste product.
Compared with prior art, the utility model has the advantage of:
The utility model vibrational power flow is reasonable, and production efficiency is high, and the PET protection film on surface can realize automatic waste discharge, does not need manual operation, is conducive to the cleanliness factor keeping product surface.The product of this sandwich construction is compared with traditional individual layer reflector plate, and shading spotlight effect has remarkable lifting, and in use, only need remove blue release film, very convenient.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with embodiment and embodiment, the utility model is described in further detail.
Embodiment 1.
As Figure 1-5, for a shading condensing film structure for optical keyboard, comprise thick 0.05mmPET diaphragm 1 from top to bottom successively, thickness is 0.023mm (thickness between 0.02-0.03mm all can) reflector plate 2 and the blue release film 3 of thick 0.075mm; Wherein, the lower surface edge of described reflector plate 2 is provided with the continuous glue district 4 that a circle width is 8mm (width between 5-10mm all can), the upper surface of described reflector plate is coated with 0.007mm black ink (not shown in FIG.), and is provided with a circle glue point 6 near the inner ring position in continuous glue district; Overhanging pulling portion 7 is provided with on the left of described PET protection film.
The thickness of described continuous glue district and described glue point is 0.02-0.04mm, and the best is 0.03mm.
PET protection film and white reflective sheet fit together, and centre adds that the black ink of certain glossiness carries out light source shielding effect, and reflector plate another side carries out the printing of fixing point glue, play and are using with keyboard sticker cooperation.
PET protection film thickness 0.05mm, carries out protection ink on surface, plays a very good protection when running into high temperature and friction.Glue is 3M import glue, and thickness 0.03mm plays product and plastic cement keyboard connection function.Reflector plate is imported material, thereon printing-ink, well can protect the glossiness of ink.Blue release film, thickness 0.075mm, carries out the release effect of glue overleaf, conveniently gets and paste product.
The utility model vibrational power flow is reasonable, and production efficiency is high, and the PET protection film on surface can realize automatic waste discharge, does not need manual operation, is conducive to the cleanliness factor keeping product surface.The product of this sandwich construction is compared with traditional individual layer reflector plate, and shading spotlight effect has remarkable lifting, and in use, only need remove blue release film, very convenient.
