Abstract
The invention discloses a new process for producing keycaps of a computer keyboard. The process is characterized in that: after the injection molding of the keycaps, a code spraying machine sprays required characters on the surface of the keycaps; the keycaps are immersed in ultraviolet curing protection liquid for coating a layer of the ultraviolet curing protection liquid on the external surfaces of the keycaps uniformly, and the keycaps are immersed in the ultraviolet curing protection liquid till the external surfaces of the keycaps are just totally immersed in the protection liquid; and the keycaps are rotated to remove the redundant protection liquid and an uniform protection layer can be formed on the external surfaces of the keycaps after the ultraviolet curing. In the process, the characters are sprayed by the code spraying machine, so the sprayed characters can be changed under the condition of not stopping the line and the production efficiency is improved; the coating becomes uniform and the ultraviolet curing protection liquid is fully used by adopting immersion and throwing technology; and the whole production process is finished in the closed space and meets environmental protection requirements. Keycaps of different textures can be produced through the change of the formula of the ultraviolet curing protection liquid.
Description
Technical field
The present invention relates to a kind of production technology of keycaps of computer keyboard.
Background technology
At present; keycaps of computer keyboard surface printing font thereon after plastic ejection moulding; for preventing that font is worn; conventionally adopt following several method to protect font: one, in font, to print again protective layer; the scope of this protective layer is more bigger than font; in the scope of keycap upper surface, but the keyboard that this method is produced is not attractive in appearance, and in perception, font has a circle water stain around.Two, this printing process protective layer printing area is increased to whole keycap upper surface, but the method is not suitable for the keycap of hypotenuse, because cannot evenly be coated with the hypotenuse of keycap.In recent years, in order to promote the quality of keyboard, adopted the technology penetrating in spraying and mould to be coated with protective layer to it; but not environmental protection of spraying technology, overseas market is seldom used, and in mould, emission technology needs to use Special Equipment and material; invest hugely, be not suitable for vast producer and use.
Summary of the invention
The invention provides a kind of process for producing keycaps of computer keyboard; object is to solve prior art problem, no matter a kind of keycap is provided, is which kind of shape all can cover layer protective layer at its printing type face outer surface, and the production technology of environmental protection; and this production technology cost is low, is applicable to vast producer and uses.
The present invention's technical scheme adopting of dealing with problems is:
A kind of process for producing keycaps of computer keyboard; it is characterized in that: after keycap ejection formation; ink jet numbering machine is sprayed required character in key cap surface, then keycap is immersed in ultraviolet photo-curing protection liquid, makes to be evenly coated with one deck ultraviolet photo-curing on its keycap outer surface and protects liquid.Keycap rotation is dried and removes redundant protection liquid, after ultraviolet light polymerization, just on keycap outer surface, form uniform protective layer.
The height that keycap immerses in ultraviolet photo-curing protection liquid just all immerses in protection liquid and is as the criterion with keycap outer surface.
Beneficial effect of the present invention: the present invention adopts ink jet numbering machine to spray character on keycap, can, not stopping to change sprayed character in line situation, enhance productivity like this.Adopt the coating technique that soaks, gets rid of can make coating even again, more make ultraviolet photo-curing protection liquid make full use of, whole manufacturing process completes at confined space, meets the requirement of environmental protection.By ultraviolet photo-curing, protect the formula conversion of liquid can make leather hand feeling keycap, or highlight surface, or case hardness reaches the keycap of 3H.
Embodiment
Below in conjunction with specific embodiment, the present invention is described in further detail.
, after keycap ejection formation, ink jet numbering machine is sprayed required character in key cap surface.Owing to adopting ink jet numbering machine to spray character on keycap, can, not stopping to change sprayed character in line situation, enhance productivity like this.Then the keycap that is sprayed with character is immersed in ultraviolet photo-curing protection liquid; make to be evenly coated with one deck ultraviolet photo-curing protection liquid on its keycap outer surface, the height that wherein keycap immerses in ultraviolet photo-curing protection liquid just all immerses in protection liquid and is as the criterion with keycap outer surface.Keycap rotation is dried and removed after redundant protection liquid, form uniform protective layer after ultraviolet light polymerization on keycap outer surface, protection character is not worn.The thickness of protective layer can be produced according to actual needs, and its thickness can be by regulating viscosity and the rotary speed of ultraviolet photo-curing protection liquid to control.
The present invention adopts the coating technique that soaks, gets rid of can make coating even, more makes ultraviolet photo-curing protection liquid make full use of, and whole manufacturing process completes at confined space, meets the requirement of environmental protection.By ultraviolet photo-curing, protect the formula conversion of liquid can make leather hand feeling keycap, or highlight surface, or case hardness reaches the keycap of 3H.
Claims (2)
