Description

Technical Field

[0001] The invention belongs to the field of artificial crystal manufacturing, and in particular relates to a UV polymerizer for preparing artificial crystals and a method for curing the artificial crystals. Background Art

[0002] Existing artificial lenses are usually produced by machine freezing cutting, which requires cutting and molding at about minus ten degrees Celsius, and its production energy consumption and cost are high. In addition, after the raw materials are formed, they must go through grinding, polishing and other processes, which require the use of multiple machines and equipment for preparation. The artificial lenses produced by this method have a low qualified rate of finished products and are time-consuming. Because one device can only cut one artificial lens, and the polishing process has a large non-directional factor, it will eventually result in scratches and damage on the finished product, resulting in a low qualified rate of the product. The equipment is expensive, has low production efficiency, takes a long time, and the produced crystals have loop fractures, reflecting that the mechanical properties of such materials need to be strengthened. Summary of the invention

[0003] In order to solve the above problems, the present invention provides a UV polymerizer for preparing an artificial lens and a method for curing the artificial lens. The specific technical scheme is as follows:

[0004] A UV polymerizer for preparing artificial lenses: the UV polymerizer is provided with a box body and a cover body, the cover body is covered on the box body, a plurality of light holes are provided on the cover body and a mechanical arm and a touch screen controller are fixedly installed, a transparent glass sheet, a variable pitch lens and an aperture are fixedly arranged in sequence below the light holes, the aperture is connected to a UV light source and an aperture controller arranged in the box body, an ultrasonic generator is also arranged in the box body, the UV light source, the aperture controller, the ultrasonic generator and the mechanical arm are all connected to the touch screen controller, the ultrasonic generator is connected to the aperture through an empty conduit, and the UV light source is connected to the aperture through an optical fiber tube.

[0005] Furthermore, the aperture controllers are arranged in a one-to-one correspondence with the apertures.

[0006] Furthermore, the box body is provided with an air inlet and an air outlet, and the air inlet and the air outlet are both provided with fans.

[0007] Furthermore, the number of the light holes is 8 and the number of the mechanical arms is 2.

[0008] Furthermore, a movable roller is arranged at the bottom of the box.

[0009] The present invention also provides a method for curing an artificial lens using the aforementioned UV polymerizer, the steps of which are as follows:

[0010] (1) Drop the IOL stock solution into the mold and place the mold on a transparent glass sheet at the light hole of the UV polymerizer;

[0011] (2) Turn on the UV light source, and at the same time turn on the aperture and ultrasonic generator;

[0012] (3) When the aperture diameter is expanded to 7 mm, the ultrasonic generator stops working and the aperture continues to open to 15 mm;

[0013] (4) When the diameter of the light hole changes from 7 to 15 mm, a robot flips the mold and both sides of the artificial lens are evenly irradiated and cured.

[0014] Furthermore, the wavelength range of the UV light source is 300-400nm, and the light intensity is 30-60uw / cm 2 .

[0015] Furthermore, the aperture is opened uniformly in a diameter range of 0-15 mm and an opening time of 150 s; the ultrasonic generator is opened in a range of 0-70 s.

[0016] Furthermore, an artificial lens mold made of optical glass material is used.

[0017] The above control settings and times are all controlled, displayed and operated through the touch screen controller.

[0018] The invention has high production efficiency, and 8 artificial lenses can be formed at the same time in 150 seconds; the raw materials react completely, and the vertical UV light and ultrasonic auxiliary device polymerize and solidify the raw materials at the same time, and the manipulator flips the mold back and forth, so that the front and back of the lens are irradiated by UV light; the equipment can determine the light intensity according to the focal length of the artificial lens to be produced, because the larger the focal length of the production, the thicker the lens, and the more raw materials are used. From the production focal length 0D to 30D, the equipment automatically selects the corresponding light intensity 30-60uw / cm 2 .

[0019] The artificial lens manufactured by the present invention has high strength and good toughness, does not require subsequent grinding and polishing, has no obvious cytotoxicity, and has greatly improved mechanical properties compared with traditional cutting processes.
