Description

Technical Field

[0001] The utility model relates to the technical field of optical filter production, in particular to a drying device for optical filters after cleaning. Background Technique

[0002] A filter is an optical device used to select the required radiation band. A common feature of filters is that no filter can make the image of celestial bodies brighter, because all filters will absorb certain wavelengths, making the object darker. Optical filters need to be dried during the processing.

[0003] In the prior art, the patent with the authorization publication number of CN214665683U discloses an efficient drying device for optical filters. When in use, the clamping device exposed outside the drying box is used to clamp the optical filter. By pressing down the pressing plate, the movable clamp flips away from the fixed clamp. At this time, the optical filter is placed between the fixed clamp and the movable clamp. After releasing the hand, the movable clamp flips towards the fixed clamp under the action of the torsion spring to fix the optical filter between the fixed clamp and the movable clamp. It needs to fix the filters one by one, and the same is true when disassembling, which is time-consuming and laborious. Content of the Utility Model

Place the filter on the fixed clamp 9, and then, the telescopic end of the electric push rod 61 drives the cover plate 12 to move up and down through the ear seat 62. The cover plate 12 covers the opening of the drying oven 1. At this time, the movable clamp 10 approaches the fixed clamp 9, thereby clamping and fixing the filter. After drying, the cover plate 12 returns to its original position, and the movable clamp 10 moves away from the fixed clamp 9, so that the fixed state of the filter can be released.

[0024] The working principle of an optical filter drying device provided by the present utility model is as follows: Place the filter plate on the fixing clip 9. Then, the telescopic end of the electric push rod 61 drives the cover plate 12 to move up and down through the ear seat 62. The cover plate 12 covers the opening of the drying box 1. At this time, the movable clip 10 moves closer to the fixing clip 9, thereby clamping and fixing the filter plate. Then, the hot air blower 7 blows hot air into the drying box 1, and the filter plate is dried by the hot air. During the drying process, the output shaft of the servo motor 45 drives the worm 44 to rotate. The worm 44 meshes with the worm gear 42. The worm gear 42 drives the gear ring 46 to rotate. The gear ring 46 meshes with the gear 47. The gear 47 drives the fixing clip 9 to rotate through the second rotating shaft 8. The fixing clip 9 drives the movable clip 10 to rotate through the filter plate. The movable clip 10 rotates relative to the first rotating shaft 11, so that the filter plate rotates and is heated, so that it is heated evenly, thereby improving its drying efficiency. The moisture dried out enters the conical bottom position of the drying box 1. The switch valve 52 is opened, and the moisture is discharged to the outside through the drain pipe 51. After drying, the cover plate 12 returns to its original position, and the movable clip 10 moves away from the fixing clip 9, and the fixing state of the filter plate can be released.
