Description
Technical field
The present invention relates to a kind of contact lenses to transfer module, refers in particular to a kind of contact lenses of radium-shine processing of pulsed light
Transfer module.
Background technique
The function of contact lenses in recent years makes it in addition to original vision correction due to the development of colorful contact lens
Medical functions (such as myopia, long sight or the eyesights such as bifocal, multifocal medical check) outside, the functions such as more joined beauty and dress up,
Such as the eyeglasses such as colorful contact lens (color lens) or magic contact lenses (magic lens).
However, general colorful contact lens turn colored diaphragm by transfer printing head mainly in transparent contact lenses
It moves in contact lenses, the processing procedure of the colour diaphragm, is by laser engraving technology in one please refer to shown in Figure 11,12
60 surface of metal die forms the carving layer 61 of a default pattern, then is coated with colorant by the carving layer 61, makes the colorant
A colored diaphragm 62 is formed after filling solidification, and then is transferred in contact lenses, and a colorful contact lenses are formed.
It sees above-mentioned known structure in detail to be not difficult to realize that it has remained a little shortcoming, main cause is summarized as follows: due to
The processing procedure for knowing colored diaphragm 62 is by laser engraving technology in forming carving layer on metal die 60, so that 61 meeting of carving layer
So that the bottom surface of indent is formed U-shaped arcuation 611 (while refering to fig. 1 shown in 2) because radium-shine, while forming hair in 61 periphery of carving layer
Side 612 is easy mutually coagulate conjunction because of flash barrier when the colorant being caused to be inserted, substantially influences the complete of colored diaphragm 62
Property, in addition when transfer printing head needs the colour diaphragm 62 is transferred to contact lenses by metal die 60 when, the transfer printing head not only without
Method pastes colored diaphragm 62 really, so that colored diaphragm 62 is difficult to take out, which but will be scratched by flash, substantially reduce
Service life, seriously affects operating efficiency and the rate of pass, there is the necessity of improvement in fact.
Summary of the invention
Technical problem to be solved by the present invention lies in above-mentioned missing of the existing technology is directed to, a kind of pulsed light is provided
The contact lenses of radium-shine processing transfer module.
A kind of contact lenses of the radium-shine processing of pulsed light transfer module, and it includes: die and a pulsed light is radium-shine sets
It is standby, wherein the punching block is to transfer to use as pigment, and the radium-shine equipment of the pulsed light is a kind of launch time to be lower than 10-9Second surpasses
The radium-shine equipment of short pulse carries out engraving operation by the surface of the radium-shine punching block of the ultrashort pulse, makes the punching block surface except material
Indent and depict a carving layer, which forms a color layer for inserting pigment in the carving layer, and in the color
The color layer is duplicated via a rubber head from the punching block before not solidifying and is transferred by layer, is used using presenting as contact lenses color.
Wherein, the carving layer on the punching block surface forms horizontal bottom in interior bottom, and the carving layer periphery is after except material delineation
Keep flatness.
It wherein, further include a molding shell, which has a lower die and a upper mold, and the lower die is recessed with one
Body, the bottom end of the concave volume inner surface, which is formed, forms cambered surface, which then corresponds to the concave volume and form a convex body, the convex body appearance
The bottom end in face forms on one and forms cambered surface, is placed in the concave volume of the lower die via the convex body, and in the lower molding cambered surface and at
An eyeglass molding space is formed between type cambered surface, the space to be bonded operation with the color layer as a protective layer finally reinjects
Polymer material solidifies in conjunction with the protective layer and the color layer, to fashion into contact lenses.
Wherein, it when the protective layer, the color layer and the polymer material carry out curing operation, is also set by a UV illumination
It is standby that the protective layer, the color layer and the polymer material are irradiated, to promote conjunction efficiency admittedly and form acceptance rate.
Wherein, which is also mixed with curable solvent, with the solid conjunction effect of accelerated color layer.
The effect of compareing prior art: the radium-shine equipment of pulsed light of the invention is the radium-shine equipment of a ultrashort pulse, by this
Launch time is lower than 10-9The ultrashort pulse of second is radium-shine when punching block carries out engraving operation, keeps the groove floor of the carving layer
Have flatness and form horizontal surface, and the periphery of the carving layer less have flash generation, it is ensured that the punching block surface it is smooth
Property, when pigment inserts the carving layer, can not only maintain the integrality of the color layer pattern, on the other hand when rubber head need by
When the color layer takes out transfer from the carving layer, moreover it is possible to avoid rubber head from being scratched by flash, keep the steady of rubber head transfer color layer
It is qualitative, increase the efficiency and the rate of pass of processing operation, facilitates the promotion of economic benefit.

An eyeglass molding space 33 is formed between the upper molding cambered surface 322 of the convex body 321 and the lower molding cambered surface 312, it finally again will molding
The polymer material 15 of contact lenses 40 injects in the lens forming space 33 of the forming die shell 30, then to lower die 31 and upper mold
32 force pressing, allow polymer material 15 be pressed on molding cambered surface 322 and lower molding cambered surface 312 between, while with the color
Layer 13 and the protective layer 14 fitting solidification, make the color layer 13 between the protective layer 14 and the polymer material 15, with
Contact lenses 40 are fashioned into, curable solvent can be added with when which inserts punching block 10, with accelerated color layer 13 and polymer
The solid conjunction effect of material 15；In addition, can also be irradiated by a UV light irradiation apparatus 50 when contact lenses 40 carry out solid cooperation industry,
The fitting efficiency and composition acceptance rate for promoting the protective layer 14, the color layer 13 and the polymer material 15, by above-mentioned step
Suddenly, to complete forming for the contact lenses 40.
Following benefits can be obtained in the structure of above-mentioned specific embodiment: the radium-shine equipment 20 of pulsed light of the invention is one to surpass
The radium-shine equipment of short pulse is lower than 10 by the launch time-9The ultrashort pulse of second is radium-shine when punching block 10 carries out engraving operation, makes
The groove floor of the carving layer 11 maintains flatness and forms horizontal surface 111, and the periphery of the carving layer 11 less has
Flash generates, it is ensured that the planarization on 10 surface of punching block can not only maintain the color when pigment 12 inserts the carving layer 11
The integrality of 13 pattern of layer, on the other hand when rubber head, which needs to take out the color layer 13 from the carving layer 11, to be transferred, moreover it is possible to keep away
Exempt from rubber head to be scratched by flash, keep the stability of rubber head transfer color layer 13, efficiency and the finished product for increasing processing operation are excellent
Rate facilitates the promotion of economic benefit.
The above, a preferred embodiment only of the invention, when cannot be limited the scope of implementation of the present invention with this；
I.e. big equivalent changes and modifications made according to the patent scope of the present invention should still belong to the range that the invention patent covers
