Technical Field
[0001] This utility model relates to the field of lens clamping technology, and in particular to a resin lens coating clamp. Background Technology
[0002] Resin lenses are optical lenses made primarily from synthetic resin materials through molding, injection molding, or casting processes, and belong to the category of organic lenses. Compared to traditional glass lenses, resin lenses have advantages such as light weight, high impact resistance, less brittleness, and flexible processing, making them widely used in eyeglass lenses, optical equipment, and protective applications. Common materials for resin lenses include CR-39 and polycarbonate (PC). These materials not only possess good light transmittance but can also achieve various optical properties such as scratch resistance, UV protection, blue light protection, and anti-reflection through the addition of functional coatings.
[0003] During the coating process of resin lenses, specialized fixtures are needed to hold and secure multiple sets of resin lenses to be processed on the coating base plate to ensure the smooth progress of the coating process. However, existing lens clamping fixtures often suffer from micro-indentations or localized damage on the lens surface due to unreasonable structural design. This can easily affect the uniformity and adhesion of the coating layer, thereby reducing the optical performance and lifespan of the lens. Furthermore, traditional fixtures suffer from poor versatility and cumbersome adjustments when adapting to resin lenses of different shapes and sizes, making it difficult to meet the needs of rapid changeover and batch processing of multi-specification products, thus limiting production efficiency and finished product yield. Therefore, their use has certain limitations.
[0004] Therefore, developing a resin lens coating fixture that can better protect the lens surface, prevent coating material buildup, and has high versatility is key to improving the efficiency and quality of the coating process. Based on this, we propose a resin lens coating fixture. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Refer to Figures 1 to 5 This utility model provides an embodiment of a resin lens coating fixture, including a coating base plate 1. Multiple sets of positioning and clamping components 2 are distributed on the top of the coating base plate 1. Lens bodies 3 are placed inside the multiple sets of positioning and clamping components 2. Each positioning and clamping component 2 includes a positioning placement plate 4. A placement slot 5 is opened in the middle of the positioning placement plate 4. A positioning pushing component 6 is also provided on one side of the inner wall of the placement slot 5. Through the cooperation between the elastic connector 7 and the clamping pushing component 8, and the structural design of the first sliding groove 15 matching the hand lever 11 and the second sliding groove 16 slidingly cooperating with the guide plate 9, this resin lens coating fixture can clamp and push one side of lens bodies 3 of different shapes and specifications placed inside the placement slot 5. This prevents the lens bodies 3 from becoming loose or shaking during the coating process. Simultaneously, the process will not cause minor indentations or localized damage to the edge surface of the lens bodies 3.
[0025] The positioning and pushing component 6 includes an elastic connector 7, with a clamping and pushing component 8 installed at one end of the elastic connector 7. Through the cooperation between the elastic connector 7 and the clamping and pushing component 8, the positioning and pushing component 6 can provide a stable and appropriate pushing force when clamping the lens, achieving adaptive clamping of lenses of different shapes and sizes, ensuring the lens remains stable during the coating process, and preventing loosening or shaking. The elastic connector 7 includes a guide plate 9, with two sets of compression springs 10 connected to the end of the guide plate 9 away from the clamping and pushing component 8. A hand lever 11 is installed on the top of the guide plate 9. The elastic connector 7, through the cooperation between the guide plate 9, the compression springs 10, and the hand lever 11, enables... The clamping and pushing force can be adjusted by the elasticity of the compression spring 10, making the force applied by the clamping and pushing component 8 to the lens body 3 more uniform and having a buffering effect, avoiding direct hard contact that could damage the lens. The positioning and pushing component 6 includes an arc-shaped rubber plate 12, and two sets of elastic protrusions 13 are provided on the inner side of the arc-shaped rubber plate 12. Through the cooperation between the arc-shaped rubber plate 12 and the elastic protrusions 13, the positioning and pushing component 6 can apply a uniform and gentle clamping force to the lens body 3 by utilizing the softness of the arc-shaped rubber plate 12 and the elastic buffering effect of the elastic protrusions 13, reducing the local stress concentration caused by hard contact, and effectively preventing indentations or scratches on the edge surface of the lens.
[0026] The inner wall of the placement slot 5 is provided with finger insertion slots 14 at both ends. A first sliding groove 15 is also provided on one side of the inner wall of the placement slot 5. The first sliding groove 15 matches the structure of the hand lever 11.

The top of the coating base plate 1 is provided with multiple sets of fixing screw grooves 17. The fixing screw grooves 17 match the structure of the positioning placement plate 4. The fixing screw grooves 17 and the positioning placement plate 4 are threadedly engaged. Two sets of handling handles 18 are also provided at both ends of the coating base plate 1. Through the structural design of the threaded engagement between the fixing screw grooves 17 and the positioning placement plate 4, the positioning placement plate 4 can be quickly installed and disassembled according to the specifications and shape of the lens body 3 and the use of the positioning push component 6, thereby improving the versatility and adaptability of the fixture.
[0027] Working Principle: The resin lens coating fixture designed in this scheme mainly consists of a coating base plate 1 and a positioning clamping assembly 2. The positioning clamping assembly 2 includes a positioning placement plate 4 and a positioning pushing component 6. The positioning pushing component 6, through the cooperation between the elastic connector 7 and the clamping pushing component 8, and the matching structure between the first sliding groove 15 and the hand lever 11, and the sliding cooperation between the second sliding groove 16 and the guide plate 9, can effectively clamp and push one side of the lens body 3 of different shapes and specifications placed inside the placement slot 5. Through this structural design, the lens body 3 can be prevented from loosening or shaking during the coating process, effectively ensuring the stability and uniformity of the coating. At the same time, this clamping process can avoid causing minor indentations or local damage to the edge surface of the lens body 3, ensuring the optical quality of the lens.
[0028] This solution, through the finger slots 14 provided at both ends of the inner wall of the placement slot 5 and the hand lever 11 provided at the top of the guide plate 9, not only facilitates the operator to conveniently place and remove lens bodies 3 of different shapes and specifications, but also enables the quick clamping and release of lens bodies 3 through the operation of the hand lever 11, significantly improving the efficiency of the coating operation. In conjunction with the fixing screw groove 17 opened at the top of the coating base plate 1, the threaded engagement between the fixing screw groove 17 and the positioning placement plate 4 allows for flexible and rapid installation and removal of the positioning placement plate 4 according to the specifications and shape of the lens body 3 and the configuration of the positioning push-top component 6.
