Description

Technical Field

[0001] This utility model relates to the field of optical lens testing technology, specifically a testing device for optical lens production. Background Technology

[0002] In the field of optical lens manufacturing, the optical performance and structural stability of lenses must be verified through professional testing to ensure that the finished product meets usage requirements. Currently, existing optical lens testing equipment has several shortcomings in practical applications: Firstly, most devices have unreasonable lens clamping structures, either using rigid clamps that easily lead to scratches on the lens surface and edge damage, or using elastic clamping forces that are difficult to adapt to different lens specifications, easily resulting in loosening and affecting testing accuracy. Secondly, traditional testing devices often require manual adjustment of the lens angle to achieve all-around testing, which is cumbersome and inefficient. Some devices with automatic angle adjustment functions suffer from complex structures and poor operational stability, making it difficult to balance testing convenience and result reliability. Furthermore, the overall support structure design of some devices is imperfect, making it easy for vibration and displacement to cause test data deviations during testing, further reducing the accuracy and efficiency of the testing work. These problems not only increase the testing costs in the optical lens manufacturing process but may also lead to defective products entering the market, affecting the performance of downstream equipment.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0004] The purpose of this invention is to provide a testing device for optical lens production that can effectively solve the above-mentioned technical problems.

[0007] Furthermore, the support legs are provided in three parts, which are arranged in a circular array at the bottom of the worktable.

[0008] Furthermore, a plurality of elastic clamping bodies arranged in a circular array are fixedly installed on the top of the placement plate, and the elastic clamping bodies are made of elastic sheet material.

[0009] Furthermore, the axis of the turntable is collinear with the axis of the connecting shaft, the diameter of the turntable is smaller than the width of the worktable, and the surface of the turntable is provided with a wear-resistant coating.

[0010] Furthermore, the inner wall of the hollow column is adapted to the outer wall of the connecting column.

[0011] Furthermore, the length of the extrusion rod is greater than the distance from the center of the turntable to the side of the auxiliary plate, ensuring that the extrusion rod can press against the auxiliary plate.

[0012] Furthermore, the spring is a compression spring. In its natural state, the elastic clamping body is in an initial position close to the center of the placement plate, and the spring's elastic coefficient is adapted to the clamping force requirements of the optical lens to be tested.

[0023] like Figures 1 to 4 As shown, this utility model relates to a testing device for optical lens production, comprising:

[0024] The workbench 1 has three support legs 4 fixedly connected to its bottom, arranged in a circular array. A motor base 3 is fixedly mounted on the bottom surface of the workbench 1, and a motor 2 is mounted on the base 3. A connecting shaft 12 is connected to the output end of the motor 2. A turntable 5 is fixedly connected to the end of the connecting shaft 12 furthest from the motor 2. The axis of the turntable 5 is collinear with the axis of the connecting shaft 12. The diameter of the turntable 5 is smaller than the width of the workbench 1, and the surface of the turntable 5 is coated with a wear-resistant coating. A hollow column 6 is fixedly connected to the top of the workbench 1 on the side furthest from the motor base 3. A connecting column 7 is movably connected inside the hollow column 6, and the inner wall of the hollow column 6 matches the outer wall of the connecting column 7. A placement plate 8 is fixedly connected to the top of the connecting column 7. The placement plate 8 is used to place the optical lens to be tested, and multiple components arranged in a circular array are fixedly mounted on the top of the placement plate 8. The elastic clamping bodies 10 are distributed and are made of elastic sheet material. Auxiliary plates 11 are provided on both sides of the top of the placement plate 8. The bottom surface of the auxiliary plates 11 is fixedly installed on the top surface of the worktable 1. A pressing rod 9 is fixedly installed on the outside of the connecting column 7. The length of the pressing rod 9 is greater than the distance from the axis of the turntable 5 to the side of the auxiliary plate 11, so that the pressing rod 9 can press the auxiliary plate 11. A circular block 13 is fixedly installed at the bottom of the connecting column 7. The circular block 13 is rotatably set with the annular groove opened in the inner wall of the hollow column 6. A spring 14 is fixedly installed on the bottom surface of the circular block 13. The bottom end of the spring 14 is fixedly installed on the top surface of the worktable 1. The spring 14 is a compression spring. When the spring 14 is in its natural state, the elastic clamping body 10 is in the initial position close to the center of the placement plate 8, and the elastic coefficient of the spring 14 is adapted to the clamping force requirements of the optical lens to be tested.

[0025] Working principle: First, the optical lens to be tested is placed on the placement plate 8. At this time, the elastic clamping bodies 10 (made of elastic sheet material) arranged in a ring array on the top of the placement plate 8 initially adhere to the outer wall of the lens under their own elasticity, realizing the pre-fixation of the lens. Then, the motor 2 installed on the motor base 3 on the bottom surface of the worktable 1 is started. The output end of the motor 2 drives the turntable 5 to rotate through the connecting shaft 12 (the axis of the turntable 5 is collinear with the axis of the connecting shaft 12 to ensure rotational stability). As the turntable 5 rotates, its edge will contact the pressing rod 9 fixedly installed on the outside of the connecting column 7 and generate a pressing force. Since the length of the pressing rod 9 is greater than the distance from the center of the turntable 5 to the side of the auxiliary plate 11, the pressing rod 9 will drive the connecting column 7 to rotate along the inner wall of the hollow column 6 (the inner wall of the hollow column 6 is adapted to the outer wall of the connecting column 7) after being subjected to force. At the same time, the round block 13 at the bottom of the connecting column 7 The rotating parts will rotate synchronously within the annular groove on the inner wall of the hollow column 6. The spring 14 (a compression spring) fixedly installed on the bottom surface of the round block 13 will undergo elastic deformation due to the rotation and slight displacement of the connecting column 7. This deformation, in turn, will cause the connecting column 7 to drive the placement plate 8 to maintain a stable posture through the reaction force. During the continuous rotation of the turntable 5, the intermittent compression of the extrusion rod 9 and the turntable 5, combined with the elastic restoring effect of the spring 14, can drive the placement plate 8 and the lens to be tested to rotate slowly, so as to perform testing operations on the lens from different angles. The elastic coefficient of the spring 14 is pre-adapted according to the lens clamping force requirements, which can ensure stable clamping of the lens (the elastic clamping body 10 is always close to the center of the placement plate 8) while avoiding damage to the lens. Throughout the process, the three support legs 4 arranged in a circular array at the bottom of the worktable 1 provide stable support for the entire device, ensuring the reliability of the testing process.
