Description
Technical field
This utility model is related to contact lenss production and processing technical field, more particularly to a kind of contact lenss lathe.
Background technology
Contact lenss, are also corneal contact lenss, be that one kind is worn on cornea, to correct defects of vision or protect eyes
Eyeglass.Contact lenss not only from appearance with convenience in terms of bring to the ametropia patient such as myopia, hypermetropia, astigmatism it is very big
Improvement, and the visual field is broad, true to nature regarding thing, in addition in control adolescent myopia, astigmatism development, treats the side such as special oculopathy
Face has also played special effect, receives the crowd with ocular disease such as myopia, is not doting on for the female user liked to be beautiful,
The surging market demand also promotes this industry to continue to grow up.
With contact lenss development and contact lenss using crowd continuous growth, the manufacture requirements of contact lenss are more
It is accurate, clean and efficient.The basic technology method of contact lenss processing at present has rotary forming, moulding and shaping by stock removal three
Kind.

And the direction of rotation of mould, speed are by the comprehensive precise control of computer, to ensure the parameters such as shape, thickness and the diopter of eyeglass
Meet design.In rotary course, there is photopolymerization reaction in liquid charging stock under ultraviolet irradiation, forms solid-state eyeglass, then passes through
Final lens product is made after the operations such as edge polish, hydration demoulding, extraction, coloring, comprehensive quality inspection and sterilization wrap.Rotary forming
The contact lenss of technique productions have surface smooth, and soft texture is thin, wear comfortably, but it is poor to correct light-dispersing effect.
Moulding technique is to go out many set template molds according to different diopters, base curve and diameter design, then is copied
Then liquid material or solid-state blank injection die are carried out casting pressure by disposable die and punch, remaining operation be rotated into
Row is identical.The characteristics of moulding technique has efficiency high, low cost, but the eyeglass for producing is thicker, and oxygen permeability is slightly worse, and intensity
It is not good, not durable use.
Shaping by stock removal technique is cut the blank of dry state with lathe, rehydrated into soft contact lens after cutting.
Shaping by stock removal technique has easy-operating feature, and the contact lenss elasticity of production is good, and most astigmatic lenses and hard mirror of breathing freely use this
Method makes.
Therefore, the continuous improvement for user to contact lenss prescription, in recent years, shaping by stock removal technique becomes
Using relatively broad production of contact lenses, but contact lenss in prior art, can not be reliablely and stablely processed
Lathe.
