Description

Technical Field

[0001] This utility model relates to the technical field of lens processing tools, specifically a covering for lens processing. Background Technology

[0002] In lens processing, the role of the shielding component is crucial, especially in protecting the inner side of lenses that have undergone anti-fog treatment before electroplating. The main function of the shielding component is to prevent the electroplating solution from penetrating the anti-fog layer of the lens, thus ensuring that the anti-fog performance is not compromised. The presence of the anti-fog coating effectively prevents moisture condensation on the lens surface, maintaining lens clarity. However, if the electroplating solution comes into contact with the anti-fog layer during electroplating, it may damage the coating and degrade its performance. Therefore, the shielding component, through physical isolation, ensures that the electroplating solution only contacts the outer side of the lens, thereby achieving the desired electroplating effect. The shielding component is typically made of flexible materials that are resistant to chemical corrosion and high temperatures, and its design needs to be customized according to the shape and specifications of the lens to ensure a tight fit to the inner side of the lens. Its structural features include high-precision shape design and reusability, maintaining good coverage even after multiple uses; for example, the cover for lens processing disclosed in patent announcement number CN205157819U includes a cover body that can completely cover one side of the lens to be processed. The curved surface of the cover body conforms to the curved surface of the lens to be processed. The cover body has a lens receiving area that can fit with the lens to be processed. This cover allows the lens to be smoothly subjected to anti-fog treatment and electroplating treatment, achieving anti-fog on the inside and anti-fog on the outside of the same lens. The side-plated color provides both anti-fog and anti-light damage effects, making the lens suitable for various applications. However, during use, due to differences in lens shape and specifications, the covering may not be able to fully fit the inner side of the lens. In actual production, due to irregular lens shape, large curvature variations, or large manufacturing tolerances of the covering itself, there are often tiny gaps at the junction of the covering and the lens. These gaps provide a potential penetration path for the electroplating solution. In this case, the electroplating solution can easily enter the anti-fog side of the lens through the gap, causing the anti-fog surface to fail. Utility Model Content

[0003] The purpose of this invention is to provide a covering for lens processing. The lens workpiece to be electroplated is placed in the lower covering seat, with the concave surface of the lens workpiece facing the lower hollow part, so that the electroplating solution can contact the concave surface of the lens. At the same time, the upper covering plate is installed on the top of the lower covering seat through a spiral pressing structure, so that the upper covering plate presses the sealing gasket against the convex surface of the mirror and covers it. At this time, the electroplating solution can only contact the concave surface of the lens and cannot penetrate into the convex surface, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a cover for lens processing, including a lower cover base and a lower hollow portion starting from the bottom end of the lower cover base. A stepped portion is provided on the inner edge of the bottom end of the lower cover base on one side of the lower hollow portion, and the stepped portion contacts the edge of the concave surface of the lens. A sealing gasket for contacting the edge of the convex surface of the lens is placed inside the lower cover base. A lens cover plate is installed at the opening of the lower cover base above the sealing gasket. Both ends of the lens cover plate are provided with a spiral pressing structure for connecting with the lower cover base.

[0005] Preferably, the lower surface of the shielding disc on the mirror surface is provided with a recess for contacting the convex surface of the lens.

[0006] Preferably, the outer edge of the shielding plate on the mirror surface is provided with an annular lip, a sealing ring is installed at the bottom edge of the annular lip, and the top of the lower shielding seat is provided with an annular groove for the sealing ring to be inserted.

[0007] Preferably, the shielding disc on the mirror surface is made of a hard plastic component.

[0008] Preferably, the spiral pressing structure includes a protruding plate integrally formed on the outer wall of the shielding disc on the mirror surface, an internally threaded protrusion fixed on the top side of the lower shielding seat, and a locking bolt installed on the top of the protruding plate, wherein the locking bolt and the internally threaded protrusion are concentrically threaded.

[0009] Preferably, the top of the lower cover seat on one side of the internal threaded protrusion is provided with a fan-shaped recessed portion.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The covering component for lens processing has a structure in which a lower covering seat and a covering plate on the mirror surface cooperate with each other. The lens workpiece to be electroplated is placed in the lower covering seat, with the concave surface of the lens workpiece to be electroplated facing the lower hollow part so that the electroplating solution can contact the concave surface of the lens. At the same time, the upper covering plate is installed on the top of the lower covering seat through a spiral pressing structure, so that the upper covering plate presses the sealing gasket against the convex surface of the mirror and covers it. The operator can effectively cover the anti-fog coating on the convex surface of the lens, ensuring that the electroplating solution only contacts the concave surface and ensuring the overall effect of single-lens electroplating.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] Please see Figure 1-5 This utility model provides an embodiment of a covering component for lens processing, comprising a lower covering seat 1 and a lower hollow portion 101 starting from the bottom end of the lower covering seat 1. A stepped portion 102 is provided on the inner edge of the bottom end of the lower covering seat 1 on one side of the lower hollow portion 101, and the stepped portion 102 contacts the edge of the concave surface of the lens. A sealing gasket 4 for contacting the edge of the convex surface of the lens is placed inside the lower covering seat 1. A lens covering plate 2 is installed at the opening of the lower covering seat 1 above the sealing gasket 4. Both ends of the lens covering plate 2 are provided with a spiral pressing structure 3 for connecting with the lower covering seat 1. By applying appropriate pressure through the spiral pressing structure 3, it can be ensured that there are no gaps between the lens covering plate 2, the sealing gasket 4 and the lens, thereby effectively preventing the electroplating solution from seeping in. The lower surface of the lens covering plate 2 is provided with a recessed portion 203 for contacting the convex surface of the lens.

[0019] Example 2, based on Example 1, is... Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the shielding plate 2 on the mirror surface is made of hard plastic. The outer edge of the shielding plate 2 on the mirror surface is provided with an annular lip 201. A sealing ring 202 is installed at the bottom edge of the annular lip 201. The top of the lower shielding seat 1 is provided with an annular groove for the sealing ring 202 to be inserted. When the shielding plate 2 on the mirror surface is assembled with the lower shielding seat 1 through the spiral pressing structure 3, the sealing ring 202 at the bottom edge of the annular lip 201 is inserted into the annular groove of the lower shielding seat 1. As the spiral pressing structure 3 continuously forces the shielding plate 2 on the mirror surface to move downward, the sealing ring 202 is deformed by force and forms a sealing surface to prevent the electroplating liquid from seeping into the lower shielding seat 1 from one side of the shielding plate 2 on the mirror surface, and to prevent the electroplating liquid from contacting the convex surface of the lens, thereby reducing the need for rework and reprocessing due to coating failure.

[0020] The spiral pressing structure 3 includes a protruding plate 301 integrally formed on one side of the outer wall of the mirror covering plate 2, an internally threaded protrusion 303 fixed on one side of the top of the lower covering seat 1, and a locking bolt 302 installed on the top of the protruding plate 301. The locking bolt 302 and the internally threaded protrusion 303 are concentrically threaded. The top of the lower covering seat 1 on one side of the internally threaded protrusion 303 is provided with a fan-shaped recessed part.

[0021] After the staff installs the lens cover plate 2 onto the top of the lower cover base 1, the through hole inside the convex plate 301 is concentric with the internal threaded protrusion 303. Then, the convex plate 301 and the internal threaded protrusion 303 are connected by the locking bolt 302. As the locking bolt 302 is turned, the lens cover plate 2 will be gradually pressed down, so that the lens cover plate 2 applies pressure to the sealing gasket 4 and the lens, so that the upper surface of the lens can be covered.

[0022] With the pressure applied by the spiral pressing structure 3 and the shielding plate 2 on the mirror surface, the contact pressure between the lower surface of the lens and the stepped portion 102 is also increased, so as to prevent the electroplating solution from entering from the joint between the lens and the stepped portion 102.

[0023] In this embodiment, the operator first ensures the work environment is clean and tidy to avoid any possible contaminants affecting the electroplating process. The operator should wear appropriate protective equipment, including gloves, goggles, and protective clothing, to protect themselves from the electroplating solution. Simultaneously, the operator checks the integrity of components such as the lower shielding seat 1, the shielding plate 2 on the mirror surface, the spiral pressing structure 3, and the sealing gasket 4, ensuring that the lower shielding seat 1 and the shielding plate 2 are free from damage or contamination. The sealing gasket 4 should be kept dry and clean to ensure a good seal. Then, the operator carefully places the lens to be electroplated into the lower shielding seat 1, ensuring the concave surface of the lens faces the lower hollow portion 101. The operator needs to pay attention to the placement angle of the lens, ensuring that the concave surface is in complete contact with the stepped portion 102 so that the electroplating solution can smoothly cover the concave surface of the lens. After the lens is placed, the operator places the sealing gasket 4 on the convex surface of the lens. The function of the sealing gasket 4 is to prevent the electroplating solution from seeping into the convex side of the lens. To protect the anti-fog coating, the lens cover plate 2 is placed on top of the lower cover base 1. The lower surface of the lens cover plate 2 is designed to completely cover the convex surface of the lens, ensuring that no electroplating liquid can come into contact with the anti-fog coating. Finally, through the spiral pressing structure 3, the operator can gradually press down the lens cover plate 2, so that it presses the sealing gasket 4 tightly against the convex surface of the lens. Only with appropriate pressure can it be ensured that there are no gaps between the lens cover plate 2, the sealing gasket 4 and the lens, thereby effectively preventing the electroplating liquid from seeping in. After completing the above steps, the operator needs to carefully check the sealing of the entire device. This can be done by gently pressing the upper cover plate to observe whether there are any signs of electroplating liquid leakage. Once the seal is confirmed to be good, the operator can start the electroplating process, injecting the electroplating liquid into the lower hollow part 101, ensuring that the electroplating liquid only contacts the concave surface of the lens. After the electroplating is completed, the operator needs to carefully remove the lens cover plate 2 and the sealing gasket 4, and remove the lens from the lower cover base 1.
