Description

Contact lens surface modification equipment material tray fixture structure

The present invention relates to the field of contact lens technology, and in particular to a plate fixture structure for contact lens surface modification equipment.

According to reports, existing contact lenses mainly focus on chemical modifications such as changing the hydrophilicity of materials. Although this chemical modification method can increase the water content of the lens, its manufacturing process is complicated and time-consuming, prone to errors, and has high manufacturing costs, which does not meet the modern industry's demand for high efficiency and low cost.

Therefore, the inventor of this case has developed the "Moisturizing Contact Lenses and Their Manufacturing Method" with Taiwan Patent No. 112120557, which mainly inputs the working gas without water into the arc generating unit, and then the arc generating unit decomposes the working gas into plasma, and then the arc generating unit sprays the plasma on the surface of the contact lens to form grooves on the surface of the lens. The groove setting can store and circulate tear fluid to maintain the moisture between the eyeball and the contact lens for a long time, solving the problems of dry eyes and lipid deposition when wearing contact lenses for a long time.

The physical modification method adopted in the Taiwan Patent Case No. 112120557, "Moisturizing Contact Lenses and Their Manufacturing Method", is not only simple and fast in manufacturing process but also low in cost, which is in line with the modern high-efficiency and low-cost industry needs. However, the inventor of this case found in practice that when the arc generating unit sprays plasma on the surface of the contact lens, the lens placed on the tray will be affected by the plasma spraying force and deviate or even be sprayed away, thereby reducing the quality and yield of the grooves formed on the contact lens.

The reason is that the inventor of this case has developed this invention with the spirit and philosophy of continuous improvement, and with the assistance of his many years of manufacturing and design experience and knowledge in related fields, and after much ingenuity.

The present invention relates to a material tray fixture structure of a contact lens surface modification device, and its main purpose is to provide a material tray fixture structure that can stably fix the lens of the contact lens.

In order to achieve the above-mentioned implementation purpose, the inventors have developed the following contact lens surface modification equipment material plate fixture structure, which includes a fixture body and a pressing plate, wherein the fixture body includes a base and a liner, wherein a receiving groove is concavely provided on one end surface of the base, and at least one pit hole is provided at the bottom of the groove, and the liner is arranged in the receiving groove of the base, and at least one through hole is provided on the liner, and the through hole of the liner is located at the same position as the pit hole of the base. The two holes are arranged to correspond to each other to form a pit together, and a chamfer is formed on the upper edge of the through hole of the liner plate, which is inclined from the periphery of the through hole to the center direction, so as to form a conical guide portion on the upper edge of the through hole of the liner plate. The pressing plate cover is arranged on the liner plate, and at least one through hole is arranged on the pressing plate, and the through hole of the pressing plate corresponds to the position of the through hole of the liner plate, and the diameter of the through hole of the pressing plate is smaller than the diameter of the large end of the conical guide portion of the through hole of the liner plate.

Thus, when the device is used, at least one lens of a dry-lens contact lens is placed in the concave pit of the fixture body, and the periphery of the lens of the dry-lens contact lens is against the conical guide portion on the upper edge of the concave pit. When the pressing plate is placed on the fixture body, the weight of the pressing plate and the guidance of the conical guide portion on the upper edge of the concave pit are utilized. It can level and center the lens, and make the pressure plate press on the periphery of the lens to stabilize the lens. Therefore, when the plasma is sprayed on the lens surface, it can prevent the lens from being deflected or sprayed away due to the plasma spraying force, so as to effectively improve the quality and yield of the grooves formed on the lens surface.
