Description

Technical Field

[0001] This utility model relates to the field of optical lens technology, and in particular to an optical lens cold processing and polishing device. Background Technology

[0002] Optical lenses are core components of optical systems, playing an indispensable role in numerous fields. In photography, the optical lenses within a lens determine image quality, sharpness, and color reproduction. From ordinary digital cameras to professional SLR cameras and cinema cameras, high-quality optical lenses are essential for capturing fleeting moments. In microscopy, optical lenses magnify tiny objects, helping researchers observe cell structures, microorganisms, and other scientific research, making them crucial for fields such as biology and medicine. In telescopes, optical lenses collect and focus light, enabling the observation of distant celestial bodies and advancing astronomy.

[0003] In the manufacturing process of optical lenses, the surface of the lens after cold processing often has defects such as roughness, scratches, and pitting. These defects can cause light scattering and uneven refraction, thus affecting the optical performance of the lens, such as reducing image sharpness and causing aberrations. Polishing is a key process to eliminate these surface defects and improve the smoothness and flatness of the lens surface. Polishing can bring the lens surface to optical-grade precision, ensuring that light can propagate and refract according to design requirements, thereby achieving high-quality imaging and optical functions of the lens.

[0004] In existing technologies, it is difficult for the device to accurately position the lens at the polishing position, and the stability of the lens during processing cannot be guaranteed when operating robots or other automated equipment. This increases the difficulty and complexity of automated operation, reduces production efficiency, and limits the improvement of the automation level of optical lens manufacturing. To address these issues, an optical lens cold processing polishing device is proposed. Utility Model Content

[0031] 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.

[0032] Reference Figure 1 and Figure 2 An embodiment of this utility model provides an optical lens cold processing and polishing device, including an operating table 1, a fixed table 2 fixedly connected to the bottom of the operating table 1, and two pneumatic cylinders 3 slidably connected to the top of the fixed table 2. The pneumatic cylinders 3 can provide power and drive the movement of subsequent components through their extension and retraction. The driving ends of the two pneumatic cylinders 3 are fixedly connected to sliders 4. The extension and retraction of the pneumatic cylinders 3 can drive the sliders 4 to slide on the top of the fixed table 2, thereby realizing the clamping or loosening operation of the optical lens. The top of the sliders 4 is fixedly connected to clamping blocks 5, which are used to directly contact and clamp the optical lens. Their shape and material can be designed according to the characteristics of different optical lenses to ensure the clamping effect and not damage the lens.

[0033] A connecting plate 7 is rotatably connected to the inner wall of slider 4. When slider 4 moves, connecting plate 7 can rotate on the inner wall of slider 4, which plays the role of transmitting motion and changing the direction of motion. A rotating plate 6 is rotatably connected to the other end of connecting plate 7. The rotation of connecting plate 7 will drive rotating plate 6 to rotate. Rotating plate 6 is connected to multiple connecting plates 7. Through its rotation, sliders 4 at the four corners can move closer or further away at the same time, which is convenient for fixing optical lenses of different shapes and sizes, reducing the difficulty and complexity of automated operation, increasing production efficiency, and improving the automation level of optical lens manufacturing. A lifting component is fixedly connected to the top of the operating table 1. The lifting component can adjust the height position of the grinding component according to the height of different optical lenses and polishing requirements. An adjustment component is fixedly connected to the bottom of the lifting component. The adjustment component further precisely adjusts the angle and position of the grinding block 16 to adapt to the curved surface of different lenses and improve polishing accuracy.

[0034] The other end of the pneumatic cylinder 3 is fixedly connected to a fixing plate 8. The fixing plate 8 is used to fix the position of the pneumatic cylinder 3 so that it can stably provide power during operation and will not be displaced. The top of the fixing plate 8 is fixedly connected to the bottom of the slider 4. The pneumatic cylinder 3 and the slider 4 are connected through the fixing plate 8 to ensure that the power of the pneumatic cylinder 3 can be effectively transmitted to the slider 4.

[0035] The top of the operating table 1 is provided with a slide rail 9, which provides a track for the movement of the slider 4. The slider 4 is externally slidably connected to the inner wall of the slide rail 9. The slider 4 slides within the slide rail 9, ensuring the stability and linearity of the movement of the slider 4, making the clamping operation of the optical lens more accurate and reliable.

[0036] Reference Figure 1 , Figure 3 and Figure 4 The lifting assembly includes a lifting rod 10, the bottom of which is fixedly connected to the top of the operating table 1. The lifting rod 10 can extend and retract, and its extension and retraction control the height of the connecting platform 11 to accommodate optical lenses of different heights. The top of the lifting rod 10 is fixedly connected to the connecting platform 11, which serves to connect the lifting rod 10 and the adjusting assembly, so that the adjusting assembly can be stably installed on the lifting rod 10. The bottom of the connecting platform 11 is fixedly connected to the connecting block 12.

[0037] The adjustment assembly includes a connecting rod 13, the top of which is rotatably connected to the bottom of a connecting block 12. The connecting rod 13 can rotate at the bottom of the connecting block 12, providing the possibility for angle adjustment of subsequent components. A ball 14 is fixedly connected to the bottom of the connecting rod 13, and a connecting post 15 is rotatably connected to the outside of the ball 14. A grinding block 16 is fixedly connected to the bottom of the connecting post 15. The ball 14 allows the connecting post 15 at the bottom to flexibly switch between various angles, enabling the grinding block 16 to better fit the surface of optical lenses with different curvatures, ensuring that the grinding force is evenly distributed on the curved surface of the lens and improving the polishing accuracy. The connecting post 15 connects the ball 14 and the grinding block 16. Driven by the ball 14, the angle of the grinding block 16 can be adjusted to adapt to different polishing needs. The grinding block 16 is the component that directly polishes the optical lens, and its material and surface treatment determine the polishing effect and quality.

[0038] A telescopic rod 17 is fixedly connected to the bottom of the connecting block 12. An adjustment bracket 18 is rotatably connected to the bottom of the telescopic rod 17. The length of the telescopic rod 17 can be adjusted according to the polishing requirements of different optical lenses, thereby changing the position and angle of the adjustment bracket 18 and the polishing block 16. The adjustment bracket 18 can rotate under the drive of the telescopic rod 17 to further adjust the angle of the connecting column 15 to achieve a better polishing effect. A slide 19 is fixedly connected to the bottom of the adjustment bracket 18. The slide 19 plays a guiding and limiting role in the subsequent adjustment process.

[0039] The top of the polishing block 16 is provided with a sliding groove 20, which provides a sliding track for the slide 19. The outer side of the slide 19 is slidably connected to the inner wall of the sliding groove 20. The slide 19 slides in the sliding groove 20, which facilitates the adjustment of the angle of the connecting column 15, while ensuring that the connecting column 15 will not slip out during the adjustment process, so as to better achieve precise adjustment of the polishing block 16 and thus improve the polishing accuracy.

[0040] Reference Figures 1 to 3 The inner wall of the rotating plate 6 is slidably connected to the outside of the fixed platform 2. The rotating plate 6 can slide outside the fixed platform 2. With the rotation of the connecting plate 7, the position of the slider 4 can be adjusted. The top of the pneumatic cylinder 3 is slidably connected to the bottom of the rotating plate 6. This connection method allows the rotating plate 6 to rotate and adjust its position better when the pneumatic cylinder 3 pushes the slider 4 to move. Two water pipes 21 are fixedly connected to the top of the operating table 1. The water pipes 21 can deliver coolant or lubricant between the optical lens and the polishing block 16 during the polishing process, reduce the temperature during the polishing process, reduce wear, and improve polishing quality and efficiency.

[0041] Working principle: The polished optical lens is placed on the top of the operating table 1 and the pneumatic cylinder 3 is turned on to drive the slider 4 to move. The inner wall of the slider 4 rotates the connecting plate 7, which in turn drives the rotating plate 6 to rotate. The connecting plates 7 in the rotating plate 6 rotate and drive the sliders 4 at the four corners to move closer to fix the optical lens. This makes it easier to fix different optical lenses, reduces the difficulty and complexity of automated operation, increases production efficiency, and improves the automation level of optical lens manufacturing.

[0042] When the connecting block 12 descends to correspond to different optical lenses, the lifting rod 10 controls the height of the rise and fall. The ball 14 connected to the bottom of the connecting rod 13 facilitates the conversion of various angles of the bottom connecting post 15. The length of the telescopic rod 17 is controlled by the bottom adjustment bracket 18, which adjusts the angle of the connecting post 15. The slide 19 slides in the slide groove 20 to facilitate the adjustment of the connecting post 15 and prevents it from slipping out, allowing for better adjustment. By adjusting the grinding angle, the grinding tool can be better fitted to the lens surface, ensuring that the grinding force is evenly distributed on the curved surface of the lens throughout the polishing process, thereby improving the polishing accuracy, reducing surface errors, and enabling the lens to reach a higher optical quality standard.

[0043] 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.
