Description
Technical Field
[0001] The present invention relates to the field of optical detection technology, and in particular to a high-precision interferometer for optical lens detection. Background Art
[0002] An optical lens is a device made of optical glass, optical crystal or light-transmitting material. It achieves the functions of light convergence, divergence, imaging, splitting and filtering by precisely controlling the refraction, reflection or scattering of light.
[0003] As optical lenses are increasingly used in precision instruments and high-end manufacturing, the requirements for detecting their surface accuracy parameters are constantly increasing. Traditional detection methods are difficult to meet the high-precision detection needs. At this time, an interferometer for optical lens detection is needed.
[0004] Currently, the interferometers for optical lens inspection on the market are mainly composed of a light source, a detection optical path, a spectrometer and an image acquisition component. When in use, coherent light is provided by the light source, and the coherent light is adjusted by the detection optical path and the spectrometer. The measurement light is irradiated onto the optical lens, and the interference fringe pattern is collected by the image acquisition component to complete the measurement of the optical lens. However, when the device is in use, dust particles or airflow disturbances in the optical path will block the light beam or change the optical path, resulting in fringe distortion and reduced detection accuracy. The adopted technology adopts a fully enclosed optical path structure to prevent external dust from entering and can reduce the impact of airflow disturbances. However, when the device is in use, mechanical vibration will cause displacement of optical path components and fluctuation of optical path, resulting in interference fringe jitter. The existing technology reduces the vibration of the interferometer by configuring a vibration isolation platform. However, after the device is clamped, it is not convenient to adjust the posture of the measured lens, resulting in the normal direction of the measured surface being not parallel to the axis of the detection optical path, causing the measurement result to deviate from the true value and generate errors, reducing the measurement accuracy of the device and failing to meet the needs of users.

[0024] The disassembly mechanism 4 includes a hollow block 41, which is fixedly connected to the right side of the interferometer body 5. A spectroscope 42 is provided on the inner middle part of the hollow block 41. A collar 43 is fixedly connected to the outer side of the spectroscope 42. A slot 44 is provided on the outer side of the collar 43. Blocks 45 are provided on the upper and lower sides of the interior of the hollow block 41. The blocks 45 engage with the slots 44. The blocks 45 engage with the slots 44 to fix the spectroscope 42. The inner ends of the workbench 1 are rotatably connected to a rotating plate 46. The left and right sides of the rotating plate 46 are rotatably connected to a connecting plate 47. One end of the connecting plate 47 is rotatably connected to the block 45. When the block 45 on one side moves, the block 45 on the other side can be driven to move through the transmission action of the connecting plate 47 and the rotating plate 46. The inner part of the hollow block 41 is provided with a plurality of blocks 45.

The upper and lower ends of the two second springs 482 are respectively fixedly connected to the corresponding blocks 45. The pulling assembly 49 includes a pull rod 491, which is fixedly connected to the top of the upper block 45. The top of the pull rod 491 passes through the hollow block 41 and is rotatably connected to a pull ring 492. The pull ring 492 can drive the block 45 to move through the pull rod 491; Specifically, when it is necessary to measure optical lenses of different models, it is necessary to replace different spectrometers 42, pull the pull ring 492, and the pull ring 492 drives the upper block 45 to move through the pull rod 491 connected to it. During the movement of the upper block 45, the hinge point between the connecting plate 47 and the rotating plate 46 drives the rotating plate 46 to rotate around the central axis. When the rotating plate 46 rotates, the connecting plate 47 on the other side moves synchronously and drives the block 45 on the other side to move in the opposite direction. At this time, the blocks 45 on both sides are synchronously disengaged from the engaging state of the slot 44, so that the spectrometer 42 can be easily removed from the hollow block 41 for replacement, and the spectrometer 42 is inserted into the hollow block 41. The second spring 482 then pulls the block 45 into the slot 44, thereby realizing reliable fixation of the spectrometer 42, making the disassembly and fixation work more convenient and reducing the workload of the staff.

The limit plate 29 can provide guidance for the movement of the movable plate 23; Specifically, the movement of the movable plate 23 is limited by the limiting plate 29 , so that when the first screw rod 22 rotates, the movable plate 23 can move accordingly.
[0026] The front and rear sides of the top of the workbench 1 are fixedly connected with slide rails 8. The outer side of the slide rails 8 is slidably connected to the bottom of the movable seat 6. The movable seat 6 can provide guidance for the movement of the slide rails 8. Specifically, the movable seat 6 can slide on the outside of the slide rail 8 , so that the movable seat 6 has higher movement accuracy.
[0027] Working principle: When using the device, when it is necessary to correct the posture of the optical lens, the first screw 22 is rotated. When the first screw 22 rotates, it drives the movable plate 23 to move. The movable plate 23 drives the first connecting seat 25 to move through the first connecting rod 24, thereby driving the back plate 21 to rotate, and the pitch angle of the optical lens can be adjusted. The second screw 281 is rotated. The rotation of the second screw 281 drives the slider 282 to move. The slider 282 can push the second connecting seat 284 to move through the second connecting rod 283, thereby driving the hollow plate 7 to deflect, so that the posture of the optical lens can be conveniently adjusted so that the normal direction of the optical lens is parallel to the axis of the detection light path; When the optical lens needs to be fixed, the lever 371 is pulled, and the lever 371 drives the movable ring 31 to rotate. When the movable ring 31 rotates, it can push the plug-in column 33 to move through the curved groove 32, and the plug-in column 33 will then drive the movable column 34 to move. At this time, multiple movable columns 34 will simultaneously drive the clamping claws 35 to move in all directions, so that the optical lens can be placed inside the hollow plate 7. Then the first spring 363 will push the movable column 34 to move, so that the clamping claws 35 can fix the optical lens and keep the optical lens in the center position at all times. Finally, when it is necessary to measure optical lenses of different models, it is necessary to replace different spectrometers 42. By pulling the pull ring 492, the pull ring 492 can drive the upper block 45 to move through the pull rod 491. When the upper block 45 moves, the rotating plate 46 can be driven to rotate through the connecting plate 47. The rotating plate 46 then drives the block 45 on the other side to move through the connecting plate 47, so that the blocks 45 on both sides are disengaged from the slot 44, so that the spectrometer 42 can be easily removed. When the spectrometer 42 needs to be installed, the spectrometer 42 is inserted into the hollow block 41, and the second spring 482 will then pull the block 45 to engage with the slot 44, thereby fixing the spectrometer 42.
