A processing mold for an intraocular lens embryo

Abstract

The application provides an intraocular lens embryo processing mold, and relates to the field of intraocular lens embryo devices. The intraocular lens embryo processing mold is used for manufacturing an intraocular lens embryo and comprises a support. The support is slidably connected with upper and lower sliding plates, and a horizontal plate is arranged between the two sliding plates. The intraocular lens embryo processing mold is provided with a support, sliding plates, a lower mold, an upper mold and a detection module. The detection module is composed of an iron sheet, an electromagnet unit, a large spring, a light emitter and a pressure detection unit. The iron sheet is pushed down by the large spring. Whether the intraocular lens embryo can smoothly pass through the iron sheet is determined according to whether the measured value of the pressure detection unit is the same, so as to detect whether the branches of the intraocular lens embryo are deformed. Whether the branches of the intraocular lens embryo are defective is determined according to whether a dark area is generated under the irradiation of the light emitter. The intraocular lens embryo is detected by replacing the traditional naked eye detection, so that the detection is more convenient and fast, and defective products can be more easily found.

Description

Technical Field

[0001] This invention relates to the field of intraocular lens embryo device technology, specifically to a processing mold for an intraocular lens embryo. Background Technology

[0002] An artificial lens is a special lens made of synthetic materials. The shape and function of an artificial lens are similar to the lens of the human eye. When an artificial lens is implanted into the eye to replace the original lens, it allows external objects to be focused onto the lens, thus enabling the viewer to see the surrounding scenery clearly.

[0003] In the process of preparing an intraocular lens (IOL), a pre-cut lens blank is fixed in a special chuck and then milled to form a suitable IOL. A processing mold is used during fabrication, and the lens is then ground and polished after being formed in one go.

[0004] Intraocular lenses have extension branches on their sides. These branches are relatively small and are prone to deformation or damage during the grinding and polishing process, resulting in products that do not meet quality requirements. However, because intraocular lenses are small, they cannot be clearly observed with the naked eye, making it difficult to detect defective products. Summary of the Invention

[0010] It also includes a material injection module and a gas delivery module. The working ends of the material injection module and the gas delivery module are connected by hoses. The hose of the material injection module is connected to the first connecting pipe, and the hose of the gas delivery module is connected to the second connecting pipe.

[0011] Preferably, the large spring is de-energized by the electromagnet unit, causing the iron sheet to descend and come into contact with the lower mold. The artificial lens embryo is placed in the irregular through hole of the iron sheet, and the light emitted by the light emitter shines on the iron sheet.

[0020] This invention provides a processing mold for an intraocular lens preform, such as... Figures 1-7 As shown, the device used to fabricate an artificial lens preform includes a support 1. The support 1 is slidably fitted with two sliding plates 2, and a horizontal plate 13 is provided between the two sliding plates 2. Multiple lower molds 3 are fixedly installed at equal intervals on the top of the horizontal plate 13. An upper mold 4 is provided directly above the lower molds 3. An electric push rod 21 is fixedly installed between the top of the upper mold 4 and the bottom of the upper sliding plate 2. Multiple detection components are also fixedly installed at the bottom of the upper sliding plate 2, and the detection components correspond one-to-one with the upper mold 4.

[0021] When the upper slide plate 2 moves forward to its limit, the detection component is directly above the lower mold 3.

[0022] The detection assembly includes a base 5, an iron sheet 51, an electromagnet unit 52, a large spring 53, a light emitter 54, and a pressure detection unit 55. The electromagnet unit 52 is fixedly mounted on the bottom of the base 5, the pressure detection unit 55 is fixedly mounted on the top of the iron sheet 51, one end of the large spring 53 is fixedly bonded to the electromagnet unit 52, and the other end of the large spring 53 is fixedly bonded to the pressure detection unit 55. The pressure detection unit 55 is used to feed back the pressure applied by the large spring 53 to the iron sheet 51 to the computer terminal.

[0023] An irregular through hole is provided in the center of the iron sheet 51. The shape of the irregular through hole is the same as that of the artificial lens embryo. The light emitter 54 is installed at the bottom of the base 5 and is directly facing the irregular through hole.

[0024] Working principle: After the upper module 4 and the lower module 3 come into contact and close, a mold is formed. The bracket 1 is rotated 180 degrees, so that the upper module 4 and the lower module 3 are reversed. Then, acrylic resin is fed into the mold, and the acrylic resin solidifies to form an artificial lens preform.

[0025] Then, bracket 1 resets, and electric actuator 21 retracts, moving upper module 4 away from lower module 3. The artificial lens embryo is then polished. After polishing, upper slide plate 2 is pushed forward, positioning base 5 directly above lower module 3.

[0026] Then, the large spring 53 is de-energized by the electromagnet unit 52, causing the iron sheet 51 to descend and come into contact with the lower mold 3. The artificial lens embryo is placed in the irregular through hole of the iron sheet 51, and the light emitted by the light emitter 54 shines on the iron sheet 51.

[0027] Deformation detection method: If the artificial lens embryo is deformed due to grinding and polishing, the branch cannot enter the irregular through hole, and the iron sheet 51 cannot contact the lower module 3 in a local area, which will lead to the difference in the value measured by the pressure detection unit 55.

[0028] Defect detection method: If the intraocular lens embryo has a branch defect, the intraocular lens embryo cannot fill the anisotropic aperture. Under the illumination of the light emitter 54, the part of the anisotropic aperture that is not filled will be relatively dark.

[0029] The top of the lower slide plate 2 is connected to multiple connecting pipes 1 22, which are aligned with the lower mold 3. The top of the lower slide plate 2 is also connected to multiple connecting pipes 23. When the lower slide plate 2 moves forward to its limit, the connecting pipes 23 are aligned with the lower mold 3.

[0030] The bottom of the horizontal plate 13 has a round hole, and the lower mold 3 has a through injection channel, with the round hole corresponding to the injection channel.

[0031] It also includes a material injection module 6 and a gas delivery module 7. The working ends of the material injection module 6 and the gas delivery module 7 are connected by hoses. The hose of the material injection module 6 is connected to the connecting pipe 1 22, and the hose of the gas delivery module 7 is connected to the connecting pipe 2 23.

[0032] The bracket 1 includes four vertical rods 11 and four slide rails 12. The vertical rods 11 are in pairs, and the slide rails 12 are in pairs. The vertical rods 11 pass vertically through the horizontal plate 13 and are welded to the horizontal plate 13. The slide rails 12 are welded to both ends of the vertical rods 11 and slide with the slide plate 2.

[0033] The slide plate 2 has a sliding cavity 24, and a small spring 25 is fixedly installed inside the sliding cavity 24. A ball bearing 26 is welded to the movable end of the small spring 25. The vertical rod 11 has a slot that matches the ball bearing 26. This serves to fix the slide plate in place.

[0034] It also includes a support leg 8, and the outermost lower mold 3 is welded with a base shaft 31. The base shaft 31 is pivotally connected to the upper end of the support leg 8, and a storage slot 9 is placed inside the support leg 8 and below the bracket 1.

[0035] The storage slot 9 has two storage cavities. The front storage cavity is covered by a cover plate 91, and the rear storage cavity is covered by a cover plate 92. Cover plates 91 and 92 are curved surfaces to facilitate the sliding of the intraocular lens embryo into the designated storage cavity.

[0036] It also includes a polishing rod 10, with a rope fixedly tied to its end. The end of the rope is fixedly connected to the support leg 8. A small motor is installed at the front end of the polishing rod 10, and a zirconia ceramic bead is fixedly installed on the drive shaft of the small motor. The zirconia ceramic bead is used to polish the artificial lens preform. This is a conventional technique and will not be described in detail.

[0037] Working principle: Due to the presence of the injection channel in lower module 3, some acrylic resin solidifies within the injection channel during manufacturing. After inspection, connector 23 is connected to horizontal plate 13. Cover plate 91 is opened to hold the qualified intraocular lens preform. The tilting bracket 1 is flipped to supply air into the injection channel corresponding to the defective product, performing the first demolding and recovering the defective product. Then, cover plate 91 is closed, cover plate 92 is opened, and the qualified intraocular lens preform is demolded again using air supply.

[0038] In summary, the processing mold for this intraocular lens preform includes a support 1, a sliding plate 2, a lower mold 3, an upper mold 4, and a detection module 5. The detection module consists of an iron sheet 51, an electromagnet unit 52, a large spring 53, a light emitter 54, and a pressure detection unit 55. The large spring 53 unfolds to push the iron sheet 51 downwards. The pressure detection unit 55 checks whether the measured values ​​match, determining if the intraocular lens preform can smoothly pass through the iron sheet 51, thus detecting whether the intraocular lens preform branches are deformed. The presence of dark areas under the illumination of the light emitter 54 indicates whether the intraocular lens preform branches are damaged. This method replaces traditional visual inspection, making inspection more convenient, faster, and easier to detect defective products.
