Abstract
The present invention is intended to provide it is a kind of it is solid and reliable can transparent and a variety of color matchings keycap processing technology.The present invention includes sequentially forming keycap shell and internal layer using the method for quadric injection mould, wherein the keycap shell contains laser carving powder, character is sintered in the keycap shell by laser carving technology and keeps the internal layer exposed, and the internal layer uses transparent material or colorful material.The present invention is applied to the technical field of keycap processing.
Description
Technical field
The present invention relates to a kind of keycap processing technologys.
Background technique
Traditional keycap character is logical after laser carving powder forms using being directly printed on keycap or being mixed into injected plastics material
It crossing laser carving technology and sinters character into key cap surface, the former will appear the case where character is worn away in use for some time, after
The color of the character of person is limited by material and can not be difficult to achieve the effect that character light transmission.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide it is a kind of it is solid and reliable can be saturating
The keycap processing technology of bright and a variety of color matchings.
The technical scheme adopted by the invention is that: the present invention includes the following steps:
A, the material injection of laser carving powder is blended with into keycap shell；
B, internal layer is formed in the injection molding that the keycap interior of shell carries out the material without laser carving powder；
C, it then is sintered to form character on the keycap shell by laser carving technology.
Above scheme as it can be seen that the connection of the keycap made of the above method is reliable, while by being blended with laser carving powder
Material and material without laser carving powder the keycap shell and the internal layer are sequentially formed using the method for quadric injection mould and made
The overall structure of keycap is solid and reliable, while being sintered to the material for being mixed with laser carving powder by laser carving technology and make the internal layer
Exposed formation character will not influence the structure of the internal layer and the effect of color since the internal layer reaches in turn without laser carving powder
Fruit.
One preferred embodiment is, the keycap shell includes sintering portion and side wall part, the outer rim in the sintering portion with it is described
The top outer rim of side wall part is adapted and seals fixation, the sintering portion with a thickness of 0.1 to 0.5 millimeter, the side wall part
With a thickness of 0.9 to 1.5 millimeter, the internal layer is located at the lower section in the sintering portion, and the outer rim of the internal layer and the side wall part connect
It connects.
By above scheme as it can be seen that making by using the sintering portion with a thickness of 0.1 to 0.5 millimeter through the processing work
The character depth as shallow for the keycap that skill obtains, when touch, does not have apparent ladder sense, and then guarantees using comfortable.Pass through institute simultaneously
The outer rim for stating internal layer is connect with the side wall part, keeps the keycap overall structure secured, guarantees the feelings relatively thin in the sintering portion
Still there is enough intensity under condition.
One preferred embodiment is that the internal layer is transparent material or colorful material.
By above scheme as it can be seen that making the internal layer by using transparent material or colorful material, enable character
Enough with translucent effect or with specific color.
One preferred embodiment is that the bottom of the internal layer is provided with connection structure.
By above scheme as it can be seen that the connection structure is the connection knot for the mechanical bearing being commonly used on connection keyboard
Structure.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
As shown in Figure 1, in the present embodiment, the present invention includes the following steps:
A, the material injection of laser carving powder is blended with into keycap shell 1；
B, the injection molding that the material without laser carving powder is carried out inside the keycap shell 1 forms internal layer 2；
C, it then is sintered to form character on the keycap shell 1 by laser carving technology.
In the present embodiment, the keycap shell 1 include sintering portion 11 and side wall part 12, the outer rim in the sintering portion 11 with
The top outer rim of the side wall part 12 is adapted and seals fixation, the sintering portion 11 with a thickness of 0.1 to 0.5 millimeter, it is described
Side wall part 12 with a thickness of 0.9 to 1.5 millimeter, the internal layer 2 is located at the lower section in the sintering portion 11, the outer rim of the internal layer 2
It is connect with the side wall part 12.
In the present embodiment, the internal layer 2 is transparent material or colorful material.
In the present embodiment, the bottom of the internal layer 2 is provided with connection structure 21.
In the present embodiment, the bindiny mechanism 21 is the cross structure for connecting mechanical keyboard bearing or the card of common keyboard
Buckle structure or "-" type structure.
The present invention is applied to the technical field of keycap processing.
Although the embodiment of the present invention is described with practical solution, the limit to meaning of the present invention is not constituted
It makes, for those skilled in the art, is all to the modification of its embodiment and with the combination of other schemes according to this specification
Obviously.
