Description

Technical Field

[0001] This utility model relates to the field of optical filter lens technology, specifically a cleaning device for the production and processing of optical filter lenses. Background Technology

[0002] An optical filter is an optical element that can filter and select light of specific wavelengths. Its main function is to filter out unwanted spectral components in incident light, reduce background interference, and improve the contrast between the target and the background, thereby improving the signal-to-noise ratio of the system.

[0003] However, during the production of optical filters, the filters need to be polished, which generates dust. To prevent this dust from affecting the light transmittance of the optical filters, they need to be cleaned. Typically, the optical filters are placed inside an ultrasonic cleaning device, where the ultrasonic device drives the cleaning fluid to vibrate at high frequency, dislodging the impurities adhering to the surface of the optical filters. However, even after the optical filters are placed in the cleaning fluid and kept in a fixed position, the impurities will re-adhere to the surface of the optical filters as the cleaning fluid flows, resulting in incomplete cleaning. Therefore, we propose a cleaning device for the production and processing of optical filters. Summary of the Invention

[0004] To address the shortcomings of existing cleaning devices for optical filter manufacturing, this invention provides a cleaning device for optical filter manufacturing. This device features a positioning frame that drives the optical filter during cleaning, followed by rotating a rotating rod. The rotating rod causes the positioning frame to flip, which in turn moves the optical filter body, thereby activating the cleaning fluid. This improves the overall cleaning efficiency of the optical filter body and solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a cleaning device for the production and processing of optical filter lenses, including a cleaning tank filled with cleaning fluid, a limiting plate fixedly connected to the upper part of the cleaning tank, a bracket movably sleeved on the upper part of the limiting plate, a connecting plate movably sleeved inside the bracket, a vertical plate installed in the middle of the connecting plate, a first gear and a second gear respectively installed on the upper and lower sides of the vertical plate, a positioning frame fixedly connected to the inner side of the second gear, a clamping plate installed on the inner side of the positioning frame via a telescopic rod, a movable column fixedly connected to the middle of the side of the clamping plate, and a threaded sleeve movably sleeved on the outer side of the movable column.

[0006] Preferably, the cleaning tank is equipped with an ultrasonic generator that controls the high-frequency vibration of the cleaning fluid, and the positioning frame is immersed in the cleaning fluid.

[0007] Preferably, a cover plate is fixedly connected to the lower part of the bracket, and the cover plate is disposed on the upper part of the cleaning tank.

[0008] Preferably, a screw is installed inside the bracket, and the screw is threadedly connected to the side of the connecting plate.

[0009] Preferably, a rack and pinion chain is sleeved on the outside of the first gear and the second gear, and a rotating rod is fixedly connected to the middle of the first gear, the rotating rod passing through the interior of the connecting plate.

[0010] Preferably, two sets of circular clamping blocks are installed on the inner side of the clamping plate, and the optical filter lens body is clamped and installed on the inner side of the four sets of circular clamping blocks.

[0011] Preferably, the threaded sleeve and the positioning frame are threadedly connected to each other, and a spring is installed between the clamping plate and the threaded sleeve, with the spring sleeved on the outside of the movable column.

[0012] Compared with existing cleaning devices for optical filters, this invention has the following advantages:

[0013] 1. This cleaning device for the production and processing of optical filter lenses adjusts the position of the threaded sleeve inside the positioning frame by rotating it according to the different sizes of the optical filter lens body. At the same time, under the action of the spring elasticity, the extension distance of the clamping plate to the inside of the positioning frame is adjusted. Then, under the action of the spring elasticity, the circular clamping block is controlled to squeeze and limit the outside of the optical filter lens body, thereby improving the stability of optical filter lens bodies of different diameters when clamping.

[0014] 2. The cleaning device for the production and processing of optical filter lenses extends into the cleaning tank through the positioning frame. During the ultrasonic cleaning process, the rotating rod is rotated, and the rotating rod drives the second gear to rotate through the rack and pinion chain. That is, the positioning frame is flipped inside the cleaning tank. By flipping the positioning frame, the cleaning fluid can be driven to flow and the position of the optical filter lens body can be adjusted, thereby improving the overall cleaning of the optical filter lens body.

Detailed Implementation

[0021] 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.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A cleaning device for manufacturing and processing optical filters includes a cleaning tank 1 filled with cleaning fluid. A limiting plate 3 is fixedly connected to the upper exterior of the cleaning tank 1, limiting the installation position of a bracket 4. The bracket 4 is movably sleeved on the upper part of the limiting plate 3, and a connecting plate 5 is movably sleeved inside the bracket 4. A vertical plate is installed in the middle of the connecting plate 5. A first gear 8 and a second gear 9 are respectively installed on the upper and lower sides of the vertical plate. The first gear 8 and the second gear 9 are driven to rotate by a rack and pinion chain 10, thereby cleaning the optical filter. When the filter lens body 16 is cleaned, the positioning frame 12 is rotated in the cleaning solution. The positioning frame 12 is fixedly connected to the inner side of the second gear 9. The clamping plate 14 is installed on the inner side of the positioning frame 12 through the telescopic rod 13. The movable column 17 is fixedly connected to the middle of the side of the clamping plate 14. The threaded sleeve 18 is movably sleeved on the outside of the movable column 17. When the threaded sleeve 18 is rotated, the threaded sleeve 18 adjusts the position of the clamping plate 14 under the elastic action of the spring 19, ensuring that the circular clamping block 15 squeezes and limits the optical filter lens body 16 between different positions.

[0023] refer to Figure 2The cleaning tank 1 is equipped with an ultrasonic generator 2 that controls the high-frequency vibration of the cleaning fluid. The positioning frame 12 is immersed in the cleaning fluid. By filling the cleaning tank 1 with cleaning fluid and placing the ultrasonic generator 2 at the bottom of the cleaning tank 1, the positioning frame 12 moves the optical filter lens body 16 into the cleaning fluid. Then, the ultrasonic generator 2 is activated, which drives the cleaning fluid to vibrate at high frequency, thus cleaning the exterior of the optical filter lens body 16. Ultrasonic cleaning improves the overall cleaning efficiency of the optical filter lens body 16.

[0024] refer to Figure 2 A cover plate 7 is fixedly connected to the lower part of the bracket 4. The cover plate 7 is set on the upper part of the cleaning tank 1. The cover plate 7 is fixedly connected to the lower part of the bracket 4. The cover plate 7 seals the upper part of the cleaning tank 1, ensuring that the overall sealing of the cleaning tank 1 is improved when the bracket 4 is installed and the optical filter lens body 16 is cleaned, and preventing the cleaning liquid from splashing out.

[0025] refer to Figure 5 The bracket 4 has a screw 6 installed inside. The screw 6 is threaded to the side of the connecting plate 5. The connecting plate 5 is movably sleeved inside the bracket 4. At the same time, rotating the screw 6 will adjust the height of the connecting plate 5, so as to control the depth of the positioning frame 12 inside the cleaning box 1.

[0026] refer to Figure 3 A rack chain 10 is sleeved on the outside of the first gear 8 and the second gear 9. A rotating rod 11 is fixedly connected to the middle of the first gear 8. The rotating rod 11 passes through the inside of the connecting plate 5. Rotating the rotating rod 11 drives the first gear 8 to rotate. Under the auxiliary transmission of the rack chain 10, the rack chain 10 drives the second gear 9 to rotate. The second gear 9 drives the positioning frame 12 to rotate inside the cleaning box 1. Then, in the process of cleaning the optical filter lens body 16, the optical filter lens body 16 is flipped to improve the cleaning efficiency of the surface of the optical filter lens body 16.

[0027] refer to Figure 4 Two sets of circular clamping blocks 15 are installed on the inner side of the clamping plate 14. The optical filter lens body 16 is clamped and installed on the inner side of the four sets of circular clamping blocks 15. The optical filter lens body 16 is placed between the two sets of clamping plates 14 by the two sets of circular clamping blocks 15 installed on the inner side of the clamping plate 14. The two sets of clamping plates 14 drive the four sets of circular clamping blocks 15 to move inward. At the same time, the four circular clamping blocks 15 clamp the outside of the optical filter lens body 16 to ensure that the optical filter lens body 16 remains stable when clamped in the inner position of the positioning frame 12.

[0028] refer to Figure 4The threaded sleeve 18 and the positioning frame 12 are threaded together. A spring 19 is installed between the clamping plate 14 and the threaded sleeve 18. The spring 19 is sleeved on the outside of the movable column 17. By rotating the threaded sleeve 18, the position of the threaded sleeve 18 outside the positioning frame 12 is adjusted. At the same time, the movable column 17 moves inside the threaded sleeve 18, and the spring 19 pushes the clamping plate 14 to move inward. Then, during the rotation of the threaded sleeve 18, the position of the clamping plate 14 inside the positioning frame 12 is adjusted. Depending on the size of the optical filter lens body 16, the position of the clamping plate 14 inside the positioning frame 12 can be adjusted to ensure that the circular clamping block 15 squeezes and limits the optical filter lens body 16 of different sizes. Under the elastic action of the spring 19, excessive pressure is avoided when limiting the optical filter lens body 16.

[0029] Working principle: In use, the optical filter lens body 16 is placed inside the clamping plate 14. The threaded sleeve 18 is rotated, and its position is adjusted according to the diameter of the optical filter lens body 16. At the same time, the clamping plate 14 drives the circular clamping block 15 to adjust its position inside the positioning frame 12, ensuring that the circular clamping block 15 squeezes and limits the position of the optical filter lens body 16. Meanwhile, the connecting plate 5 drives the positioning frame 12 to be placed inside the cleaning tank 1, and the cover plate 7 blocks the upper part of the cleaning tank 1. The screw 6 is rotated to adjust the immersion depth of the positioning frame 12. The ultrasonic generator 2 is started, and the ultrasonic generator 2 drives the cleaning fluid to perform ultrasonic cleaning on the optical filter lens body 16. During the cleaning process, the rotating rod 11 is rotated, which drives the first gear 8 to rotate. The first gear 8 drives the second gear 9 to rotate through the rack chain 10. Then, the positioning frame 12 can be flipped. By flipping the positioning frame 12, the cleaning fluid can be circulated, improving the cleaning efficiency and thus completing the cleaning of the optical filter lens body 16.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
