To achieve these goals, the following technical scheme of this utility model offer:
The press-key structure of a kind of band backlight, including backlight, transparent ground, described backlight is positioned at described ground
The back side, wherein, also includes: clean oil enamelled coating, is sprayed at the front of described ground；Prime coat, black, for shading, it is sprayed at
Region outside key label on described clean oil enamelled coating；Intermediate primer layers, silvery white, for shading, it is sprayed at described prime coat
Region outside upper key label；Top coat layer, is sprayed at the region outside key label on described intermediate primer layers.
Preferably, in the press-key structure of above-mentioned band backlight, the paint of described clean oil enamelled coating is for being mixed with clean oil
Paint.
Preferably, the paint that the paint of the paint of described clean oil enamelled coating and described top coat layer is same color.
Preferably, the paint of described clean oil enamelled coating and the paint of described top coat layer are blue paint.
Preferably, the paint that the paint of the paint of described clean oil enamelled coating and described top coat layer is different colours.
Preferably, in described clean oil enamelled coating, prime coat, intermediate primer layers, top coat layer, the thickness of each layer is not less than
0.08mm, no more than 0.20mm.
Preferably, after described prime coat, intermediate primer layers, top coat layer are formed, by the way of laser carving, described button is formed
Label.
Preferably, in described clean oil enamelled coating, prime coat, intermediate primer layers, top coat layer, the thickness of each layer is 0.10mm.
Analyzing and understand, when backlight of the present utility model extinguishes, key label can represent abundant color, at press key lamp
When lighting, key label more neatly, more glittering and translucent, press key lamp the most of the present utility model or bright or when going out, key label is all
Can significantly attract user, improve identification.
Accompanying drawing explanation
Fig. 1 is the stratiform decomposition texture schematic diagram of this utility model embodiment.
Detailed description of the invention
With detailed description of the invention, this utility model is described in further details below in conjunction with the accompanying drawings.
As it is shown in figure 1, this utility model includes backlight 1, transparent ground 2, the preferred LED of backlight 1 and be positioned at ground 2
The back side.Clean oil enamelled coating 3, prime coat 4, intermediate primer layers 5, finish paint it is coated with successively in the front (upper surface of Fig. 1) of ground 2
Layer 6.
Specifically, clean oil enamelled coating 3 is painted the paint such as preferably blue, and it is sprayed at the front of ground 2.Its face
Color is the most unrestricted, though using the colored colored varnish, but specifically what color, depend on the color of product requirement.Spray it
Before, in being painted, clean oil is added in mixing, to prevent in later stage operation, penetrates this layer, calcination ground 2 during laser laser carving.
Prime coat 4, the Main Function of intermediate primer layers 5 are shading, prevent the light of backlight 1 from divulging out from bottom, by
(i.e. black paint has stronger shaded effect, and silvery white colored paint is permissible to have stronger shaded effect in black paint and silvery white colored paint
Reduce finish paint aberration), therefore prime coat 4 is preferably black, is sprayed at the region outside key label on clean oil enamelled coating 3, in
Between enamelled coating be then preferably silvery white, it is sprayed on prime coat 4 region outside key label.
Color of paint used by top coat layer 6 is preferably identical with the color of paint of clean oil enamelled coating 3, and top coat layer 6 is also preferably
Blue paint, it is sprayed on intermediate primer layers 5 region outside key label.Color of paint and clean oil due to top coat layer 5
The color of paint of enamelled coating 3 is identical, such as, be blueness, therefore can be that the color of button is cleaner and tidier, more glittering and translucent.Certainly,
The color of top coat layer 6 does not the most limit, and actual color is with product demand, such as: white, green, powder etc..Oil used by top coat layer 6
Paint color can also be different from the color of paint of clean oil enamelled coating 3, by the combination of different colors, button can be made to have abundant
Color represent.
It is emphasized that four layers are uniformly sprayed paint and can obtain prominent technique effect, such as: light-proofness is strong, it is not required that
The region of light leak never light leak；Color will not have aberration, what color of surface requirements just can reach expected from require color.
For the key label of formation the present embodiment simple, efficient, the present embodiment have employed laser laser carving when being formed
Technique, that is, after prime coat 4, intermediate primer layers 5, top coat layer 6 are formed, form key label by the way of laser carving.Specifically
For, in the present embodiment, the purpose of spraying multilamellar paint is exactly shading, and the light preventing backlight 1 from sending is divulged out from bottom
Come, it is ensured that button need not light-emitting zone not light leak, especially black paint, silvery white colored paint and all has stronger shaded effect；This
Outward, multilamellar is sprayed paint and the outermost paint in surface can also be made to meet outward appearance.Carry out laser carving key label operation, only phase on ground 2
Answer which floor paint such as the prime coat 4 of key label visuals, intermediate primer layers 5, top coat layer 6 all to carve, only stay and be close to the end
The layer of transparent skin of paint 3 of material 2 so that when backlight 1 lights, only key label region is shinny, does not works at backlight 1
Time, key label shows the color of the clean oil enamelled coating 3 being close to ground 2.
Further, in clean oil enamelled coating 3, prime coat 4, intermediate primer layers 5, top coat layer 6, the thickness of each layer paint is the most equal
Not less than 0.08mm, no more than 0.20mm, such as preferably 0.10mm, 0.12mm, 0.15mm.It practice, the thickness to paint
Do not require, but paint the thinnest meeting and allow button finish paint and other parts of product have aberration, paint the thickest meeting and make the duration of laser carving the longest,
Therefore, each layer thickness is selected between 0.08mm～0.20mm, button finish paint and product gas part can be avoided to have aberration, make
The visual effect of product is more preferable, it is also possible to reduces the laser carving time, makes manufacturing process simple.
Uniform in order to ensure the thickness of skin of paint, use automatic paint spraying apparatus to spray paint: to set the spray adjusting nozzle
The amount of penetrating and spray time, pass through automatic spraying equipment one by one with at the uniform velocity conveyer belt.
Analyzing and understand, this utility model can obtain good visual effect, and backlight is bright or does not works, and all can attract to use
Family notes, has good vision.I.e. when the backlight light on and off of button, there is obvious attracting mark in key label region
Will, when the backlight of button does not works, key label region has abundant color to represent, when press key lamp lights, key label
Region more neatly, more glittering and translucent.
This utility model has a wide range of applications, and is not only able to use at intelligent electronic device (such as communication terminal, object for appreciation
Tool) on, it is also possible to use on other products, the button on such as main equipment, the button etc. on automobile.
As known by the technical knowledge, this utility model can be by other essence without departing from its spirit or the reality of essential feature
The scheme of executing realizes.Therefore, embodiment disclosed above, for each side, all it is merely illustrative, is not only
's.All in the range of this utility model or be equal to the change in the range of this utility model all by this utility model bag
Contain.
