Description
Technical field
The present invention relates to a kind of contact lenses processing procedure, espespecially a kind of stripper apparatus of the ultrasonic for the contact lenses manufacture and be applied to manufacture the method for contact lenses.
Background technology
Due to scientific and technological prosperity, the various information products with display screen are omnipresent, as TV, desktop computer, notebook computer, panel computer, intelligent mobile phone etc., make the modern closely use for a long time the chance of eyes to increase, and allow the eyes rest of seldom having an opportunity to loosen, make near-sighted population grow with each passing day, not only the number of prestowage glasses increases, select the number of prestowage contact lenses also thereupon more and more many, add the development of colorful contact lens, impel and wear colorful contact lens and make the eyes variable color become one trend, therefore the demand of contact lenses is significantly increased, and the manufacture production technology of contact lenses, also come into one's own gradually.
The manufacture of known contact lenses is broadly divided into three kinds, includes turning method (Lathe cutting), die casting (Cast molding) and revolves modulus method (Spin casting).The manufacture of turning method, for injection liquid glassy polymer material in glass tube, make it after high warm hardening, through the circular tablet of round cut, and through turning, edging and polishing, again eyeglass is immersed in buffer solution and makes it softening, the eyeglass that this cutting and grinding goes out is for having not cracky, the advantage such as of a tightly knit structure, but manufacturing cost is too high, make the eyeglass of volume production peddle selling at exorbitant prices and do not have an advantage, therefore often be used in and need on special customized ophthalmic lens market.
Revolving modulus method announces as described in No. I261024 as the TaiWan, China patent of invention, be mainly contact lens material is injected and can supply the mirror optical mould processed of rotation, and utilize centrifugal force on average to be scattered in mirror optical mould die cavity internal face processed by contact lens material, recycle afterwards UV-irradiation and make its sclerosis, finally, again by its edging, and be immersed in buffer solution softening by eyeglass, after absorbing buffer solution, eyeglass just can expand, the disengaging mould of nature can form contact lenses, this mode has low manufacturing cost and high resiliency production changes, the eyeglass of producing is also liked by the consumer, and the die casting rule is announced as described in No. I330129 as the TaiWan, China patent of invention, for aqueous polymeric material is injected between two moulds, and after utilizing two mold die, mode such as recycling ultraviolet light etc. makes aqueous polymeric material sclerosis, and completes after eyeglass being immersed in buffer solution make it softening.
Yet, above-mentioned no matter be to revolve modulus method or die casting, contact lenses are after sclerosis, all need just can carry out the demoulding through aquation, and must be soaked in the detection of carrying out defective products in liquid, so the mode of the aquation demoulding not only expends time on processing procedure, and more can affect the accuracy that follow-up defective products detects, therefore the necessity be improved.
Summary of the invention
Main purpose of the present invention, be to solve known contact lenses when the demoulding, essential through aquation, and have expending time in and affect the problem of subsequent detection accuracy.
For reaching above-mentioned purpose, the invention provides a kind of ultrasonic stripper apparatus, include a ultrasonic vibrating device, and pass shake part and a mould.This ultrasonic vibrating device is in order to produce a ultrasonic, this biography shake part is connected with this ultrasonic vibrating device and transmits this ultrasonic, this mould is connected with this biography shake part, and comprise one and be subject to shake face, a profile surface and a ultrasonic transfer part, this is subject to shake face and this biography shake part join and receive this ultrasonic from this biography shake part, this profile surface attaches for contact lenses, and this ultrasonic transfer part is located at this and is subject between shake face and this profile surface.
Wherein, this ultrasonic is passed to this profile surface of this mould via this ultrasonic transfer part, makes generation one between this profile surface and this contact lenses shake and make these contact lenses break away from this profile surface.
For reaching above-mentioned purpose, the present invention separately provides a kind of method of applying the manufacture contact lenses of ultrasonic stripper apparatus, comprises following steps:
One contact lens material is inserted between one first mould and one second mould and suppressed;
Irradiate this contact lens material with a light, this contact lens material is solidified between this first mould and this second mould and form contact lenses;
This first mould is separated with this second mould, and these contact lenses are attached on this first mould; And
Be connected with this first mould with a ultrasonic stripper apparatus, and produce a ultrasonic that is passed to this first mould and make this first mould produce vibrations, these contact lenses break away from this first mould by this vibrations.
Thus, the present invention by this ultrasonic stripper apparatus, makes contact lenses after solidifying, do not need through aquation, and vibrations that can directly produce via ultrasonic and break away from this mould, and at least there is following advantages:
1. demould time is extremely short, less than a second, promotes speed of production.
2. after the demoulding, these contact lenses are still drying regime, improve the accuracy of subsequent detection flow process, reduce the chance of defective products output.
