Description

Technical Field

[0001] This utility model relates to the field of lens thickness detection technology, specifically a thickness detection device for infrared imaging optical lenses. Background Technology

[0002] Infrared imaging optical lenses are optical elements specifically designed for the infrared spectral range, primarily used in infrared imaging, infrared detection, infrared spectral analysis, infrared guidance, and laser applications. Thickness measurement of optical lenses is a crucial step in ensuring lens quality and performance.

[0003] The existing Chinese patent publication number CN221706486U, entitled "An Optical Lens Thickness Detection Device," clearly states in its background technology that "the optical lens thickness detection device, through the setting of the positioning component, can rotate the worm gear by turning the knob when fixing the optical lens, so that the worm wheel drives the screw to rotate, which allows the screw sleeve to pull the positioning rod through the rotating plate and slide it on the guide rod, thereby clamping and fixing optical lenses of different sizes, thus improving the application range of the detection equipment. At the same time, the rubber sleeve can buffer the positioning rod and the optical lens to avoid damaging the optical lens."

[0004] However, this technology can only inspect one optical lens at a time. When inspecting multiple optical lenses, staff need to continuously pick up and put down the optical lenses, which reduces the inspection efficiency of optical lenses. Utility Model Content

[0005] The purpose of this invention is to provide a thickness detection device for infrared imaging optical lenses, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A thickness detection device for infrared imaging optical lenses includes a mounting box and an optical lens body. The mounting box has multiple mounting slots inside, and a placement platform is located at the bottom of each mounting slot. The optical lens body is placed on the placement platform. A connecting plate is located inside each mounting slot, and a detection component is located at the bottom of the connecting plate. The detection component is used to detect the thickness of the optical lens. A circular groove is located at the top of each mounting slot, and a circular block is movably disposed inside the circular groove. A driving component is located above the mounting box, and the driving component is used to simultaneously drive the multiple circular blocks to rotate.

[0008] In a preferred embodiment of the present invention, the detection component includes a spring, a mounting plate is provided at the bottom of the spring, and a detection block is provided on the inner side of the bottom of the mounting plate.

[0009] In a preferred embodiment of this utility model, limiting blocks are provided on both sides of the connecting plate and the mounting plate, and limiting rails are provided on both sides inside the mounting groove, with the limiting blocks and the limiting rails being slidably connected.

[0010] In a preferred embodiment of this utility model, mounting strips are provided on both sides of the bottom of the mounting plate, the bottom of the mounting strips is flush with the bottom of the detection block, and a scale line is provided on the outer side of the limiting rail on one side.

[0011] In a preferred embodiment of this utility model, a threaded opening is provided on the inner side of the circular block, and a threaded rod is provided on the top of the connecting plate, wherein the threaded opening and the threaded rod are threadedly connected.

[0012] In a preferred embodiment of this utility model, an annular groove is provided on the inner side of the circular groove, and a limiting ring is provided on the outer side of the circular block, with the limiting ring being movably connected to the annular groove.

[0013] In a preferred embodiment of the present invention, the drive assembly includes a rotating shaft, and rotating handles are provided on both outer sides of the rotating shaft.

[0014] In a preferred embodiment of this utility model, a plurality of worm gears are provided on the rotating shaft, and a worm wheel is provided on the top of the circular block, wherein the worm gears mesh with the worm wheel.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: When using this device, multiple optical lenses are placed on different platforms. By rotating the handle on the outside, the shaft rotates, which in turn drives the worm gear to rotate the worm wheel, causing multiple circular blocks to rotate simultaneously. The threaded joint drives the threaded rod, causing multiple connecting plates to rise and fall. When the connecting plate falls to a certain position, the spring pushes the mounting plate, causing the detection block to contact the optical lens. The operator observes the position of the bottom of the outer mounting strip at the scale line to determine the thickness of the optical lens. This allows for simultaneous thickness detection of multiple optical lenses, thereby increasing the efficiency of optical lens detection.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model discloses a thickness detection device for infrared imaging optical lenses, including a mounting box 1 and an optical lens body 11. The mounting box 1 is the main structure of the device and is used to install other structures. The optical lens body 11 is the optical lens. Multiple mounting slots 12 are provided inside the mounting box 1. The mounting slots 12 are mounting structures. A placement platform 13 is provided at the bottom inside the mounting slots 12, and the optical lens is placed on the placement platform 13.

[0026] The mounting slot 12 is equipped with a connecting plate 3, which is a connecting structure. A detection component is located at the bottom of the connecting plate 3 to detect the thickness of the optical lens. The detection component includes a spring 31, and a mounting plate 33 is located at the bottom of the spring 31. The spring 31 connects the connecting plate 3 and the mounting plate 33. A detection block 4 is located on the inner bottom of the mounting plate 33. The optical lens center position is adjusted and moved to the bottom of the detection block 4. Limiting blocks 34 are located on both sides of the connecting plate 3 and the mounting plate 33. Limiting rails 32 are located on both sides inside the mounting slot 12. The limiting blocks 34 and the limiting rails 32 are in a sliding connection. The limiting rail 32 limits the limiting block 34, thereby allowing the connecting plate 3 and the mounting plate 33 to move smoothly up and down. The mounting plate 33 has mounting strips 41 on both sides of its bottom, with the bottom of the mounting strips 41 flush with the bottom of the detection block 4. A scale line 14 is set on the outer side of one limiting rail 32. The connecting plate 3 drives the mounting plate 33 to descend, thereby allowing the detection block 4 to contact the optical lens. The spring 31 contracts, allowing the connecting plate 3 to descend further. By observing that the bottom of the outer mounting strip 41 is at the position of the scale line 14, the operator can determine the thickness of the optical lens.

[0027] The top of the mounting slot 12 is provided with a circular slot 2, which is the mounting structure. A circular block 25 is movably arranged inside the circular slot 2. An annular groove 21 is provided on the inner side of the circular slot 2. A limit ring 45 is provided on the outer side of the circular block 25. The limit ring 45 is movably connected to the annular groove 21, that is, the limit ring 45 is stuck in the annular groove 21 and rotates, thereby causing the circular block 25 to be stuck in the circular slot 2 and rotate. A drive assembly is provided on the top of the mounting box 1. The drive assembly is used to drive multiple circular blocks 25 to rotate simultaneously. A threaded opening 43 is provided on the inner side of the circular block 25. A threaded rod 42 is provided on the top of the connecting plate 3. The threaded opening 43 and the threaded rod 42 are threadedly connected. The drive assembly includes a rotating... Shaft 22 is rotatably mounted above the mounting box 1. Rotary handles 24 are provided on both sides of the outer side of the shaft 22. Multiple worm gears 23 are provided on the shaft 22. A worm wheel 44 is provided on the top of the round block 25. The worm gears 23 mesh with the worm wheel 44. That is, by rotating the rotary handles 24 on the outside, the shaft 22 is rotated. The worm gears 23 drive the worm wheel 44, thereby causing multiple round blocks 25 to rotate simultaneously. The threaded rod 42 is driven through the threaded port 43, thereby causing multiple connecting plates 3 to rise and fall. That is, the thickness of multiple optical lenses is simultaneously detected by the detection component at the bottom, thereby increasing the detection efficiency of optical lenses.

[0028] The working principle of this utility model is as follows: When using the device, multiple optical lenses are placed on different placement platforms 13, and the center position of the optical lenses is adjusted and moved to the bottom of the detection block 4. By rotating the handle 24 on the outside, the rotating shaft 22 is rotated, and the worm gear 23 drives the worm wheel 44, thereby causing multiple circular blocks 25 to rotate simultaneously. The threaded rod 42 is driven by the threaded port 43, thereby causing multiple connecting plates 3 to rise and fall. When the connecting plate 3 falls to a certain position, the spring 31 pushes the mounting plate 33, thereby causing the detection block 4 to contact the optical lens. The limiting rail 32 limits the limiting block 34, thereby causing the connecting plate 3 and the mounting plate 33 to rise and fall smoothly. The operator observes that the bottom of the outer mounting strip 41 is at the position of the scale line 14, thereby obtaining the thickness of the optical lens. That is, the thickness of multiple optical lenses is detected simultaneously, thereby increasing the detection efficiency of optical lenses.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
