[0002] The optical lens is one of the core components of a camera, and its performance directly affects the camera's image quality and optical performance. In modern camera technology, optical lenses not only need to possess performance characteristics such as high resolution, low distortion, and high contrast, but also need to be able to adapt to different application scenarios and environmental conditions. Therefore, the manufacturing and calibration precision of the optical lens is crucial to the overall performance of the camera.

[0003] A typical high-precision optical lens calibration device consists of a base, an adjustment mechanism, a cleaning mechanism, and a sliding mechanism. Therefore, the base is the foundation of the entire calibration device, providing a stable support platform. The adjustment mechanism is responsible for adjusting the position and angle of the optical lens. The cleaning mechanism is used to clean the surface of the optical lens during the calibration process to ensure that the lens surface is free of dust, stains, and other impurities. The sliding mechanism is used to achieve smooth movement and positioning of the lens on the support plate.

[0004] However, some existing devices can only achieve adjustment in one direction, which cannot meet the needs of optical lenses for precise adjustment in multiple directions and cannot ensure the stability of the lens during the adjustment process, thus affecting the adjustment effect and repeatability. Therefore, a high-precision optical lens adjustment device is proposed to solve the above problems. Summary of the Invention

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0031] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a high-precision optical lens adjustment device, including a base 1, which is designed to provide good support capabilities. An adjustment mechanism 2 is provided inside the base 1. A support plate 3 is fixedly connected to the top of the adjustment mechanism 2. A clamping mechanism 4 is provided on the top of the support plate 3. A lens placement 5 is provided on the top of the support plate 3.

[0032] The adjusting mechanism 2 includes two rotating rods 21, designed to provide good lateral rotation capability. The two rotating rods 21 are rotatably connected to the inner walls of the base 1 on both sides. A support column 22 is fixedly connected to an adjacent side of the two rotating rods 21, also designed to provide good rotation capability. A rotating column 23 is rotatably connected to the top of the support column 22, designed to provide good vertical rotation capability. The rotating rods 21 can also rotate in different directions. A support plate 24 is fixedly connected to the top of the rotating column 23, designed to provide good support capability. A limit assembly, including a toggle plate 25, is fixedly connected to the outer side of the support plate 24, designed to provide good connection capability. The rotating column 23 and the support column 22 can be rotated and adjusted by rotating the toggle plate 25. The toggle plate 25 is externally fixedly connected to the outer side of the support plate 24. The top of the toggle plate 25 is fixedly connected to the sliding plate 26, which is designed to provide good sliding ability, allowing the toggle plate 25 to be extended. The sliding plate 26 is provided with a locking rod 27 inside, which is designed to provide good locking ability, allowing the locking rod 27 to be rotated out to make it vertical. Then, by sliding the locking rod 27, it can be slid into the top side of the base 1, which can fix the support plate 24 and prevent displacement when placing the lens 5. The locking rod 27 is externally slidably connected to the top side of the base 1.

[0033] Reference Figure 3 and Figure 4The clamping mechanism 4 includes two sliding blocks 42, designed to provide good support and sliding capabilities. The two sliding blocks 42 are slidably connected to the top of the support plate 3. Clamping rods 43 are fixedly connected to adjacent sides of the two sliding blocks 42, designed to fix the lens 5 and facilitate stable adjustment for subsequent installation. A sliding groove 41 is provided on the top of the support plate 3, designed to provide good sliding space. The two sliding blocks 42 are slidably connected to the inside of the sliding groove 41. The lens 5 is located on the adjacent side of the two clamping rods 43. A rotating column 44 is rotatably connected to the top of the support plate 3, designed to provide good rotation capabilities. The rotating column 44 rotates on the top of the support plate 3. Transmission rods are fixedly connected to both sides of the rotating column 44. The rod 47 is designed to provide good transmission capability, allowing the rotation of the rotating column 44 to drive the transmission rod 47 to rotate accordingly. The top of the two transmission rods 47 is rotatably connected to the connecting rod 45, which is designed to provide good connection capability, allowing the connecting rod 45 to rotate when the transmission rod 47 rotates. Then, through the sliding and limiting provided by the sliding groove 41, the two clamping rods 43 are brought closer together to fix the lens 5. The other side of the connecting rod 45 is rotatably connected to the bottom of the sliding block 42. The bottom of the rotating column 44, that is, the side near the support plate 3, is fixedly connected to the actuating disk 46, which is designed to provide good rotation capability, allowing the rotating column 44 to rotate when the actuating disk 46 rotates, so that the two clamping rods 43 are centered and brought closer together.

[0034] Working Principle: First, the lens 5 needs to be placed on top of the support plate 3. At this time, the adjustment mechanism 2 is in its initial state, and the support plate 24 is connected to the base 1 through the pillar 22 and the rotating rod 21, providing stable support for the lens 5. In order to precisely adjust the position of the lens 5, the operator can rotate the support plate 24 by turning the toggle plate 25. The movement of the toggle plate 25 causes the rotating column 23 and the pillar 22 to work together, thereby realizing the rotation adjustment of the support plate 24 in different directions, thus changing the position and angle of the lens 5. After the position of the lens 5 is adjusted to a suitable position, the support plate 24 needs to be fixed to prevent the lens 5 from shifting during the adjustment process. At this time, the operator can rotate the locking rod 27 inside the sliding plate 26 to a vertical state, and then slide the locking rod 27 into the corresponding structure on the top side of the base 1, thereby fixing the support plate 24 in the current position and ensuring the stability of the lens 5 in the subsequent adjustment process.

[0035] First, place the lens 5 on top of the support plate 3, positioning it on the adjacent outer side of the two clamping rods 43. At this point, the clamping mechanism 4 is in its initial state, with the two sliding blocks 42 in their initial positions in the sliding groove 41, and the clamping rods 43 not yet clamping and fixing the lens 5. To clamp the lens 5, the operator can initiate the clamping process by rotating the dial 46. The rotation of the dial 46 causes the rotating column 44, which is fixedly connected to it, to rotate. The rotation of the rotating column 44 causes the transmission rods 47 on both outer sides to rotate accordingly. The rotation of the transmission rods 47 further causes the connecting rod 45, which is rotatably connected to its top, to swing. The swing of the connecting rod 45, through its other side's rotatable connection to the bottom of the sliding block 42, allows the sliding block 42 to slide within the sliding groove 41. The sliding groove 41 not only provides sliding space for the sliding block 42 but also serves as a limit, ensuring that the sliding direction of the sliding block 42 is accurate. As the sliding block 42 slides, the clamping rods 43 fixedly connected to its adjacent side gradually move closer to each other. Finally, the two clamping rods 43 clamp and fix the placed lens 5, providing stable support and precise positioning for subsequent adjustment work.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
