Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a high-precision detection device for optical lens processing. Background Technology

[0002] In the field of modern optics, optical lenses, as key components, are widely used in photographic and video equipment, microscopes, telescopes, optical instruments, and various optical imaging systems. High-precision optical lenses not only provide clearer and more accurate images, but also effectively reduce optical defects such as aberrations and chromatic aberrations, thereby improving the quality and competitiveness of optical products.

[0003] In the manufacturing process of optical lenses, the inspection stage is crucial. Traditional optical lens inspection methods mainly rely on manual operation. Inspectors, using their naked eyes and extensive experience, rotate the lens from multiple angles under a ring light source to determine whether there are surface defects, internal flaws, or other problems. However, this manual inspection method has several shortcomings. First, the human eye is prone to fatigue after prolonged work, and the inspector's visual sensitivity gradually decreases with working hours, leading to a reduced ability to identify subtle defects in the lens and making it difficult to guarantee the consistency and accuracy of the inspection results. Second, different inspectors have varying levels of experience and differing standards for judging lens quality, resulting in unstable inspection results that cannot meet the needs of large-scale, standardized production. Moreover, manual inspection is inefficient, slowing down production speed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-precision inspection device for optical lens processing, which has the advantages of achieving high-precision and high-efficiency inspection and solves some of the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a high-precision inspection device for optical lens processing, comprising an inspection table, an ear plate rotatably mounted near the center of the back plate of the inspection table, a fixing ring fixedly connected to the center of the ear plate, a filter fixedly connected to the lower end of the fixing ring, an electric push rod fixedly mounted near the left and right sides of the front end of the ear plate, the telescopic ends of the electric push rods passing through the fixing ring and fixedly connected to adapters, a secondary roller rotatably mounted inside the adapters, a double-ear connector fixedly connected near the rear end of the fixing ring, a main roller rotatably mounted inside the double-ear connector, a rubber sleeve fixedly fitted to the outer side of the main roller, a ring light source inspection lamp fixedly mounted near the upper end of the back plate of the inspection table, and an HDR camera set on the table surface of the inspection table at the corresponding ear plate position.

[0006] Furthermore, the upper shaft of the main roller passes through the double-ear joint and is fixedly sleeved with a worm gear. A micro motor is fixedly installed at the upper end of the hanging ear plate near the rear side. A worm is fixedly installed at the front output end of the micro motor through a coupling. The worm and the worm gear are meshed and connected. That is, by turning on the micro motor, the optical lens can be driven to rotate.

[0007] Furthermore, an electric push rod two is rotatably installed at the lower end of the ear plate near the middle of the rear side. The lower end of the electric push rod two is rotatably installed between the back plate of the testing table and tilted backward at a certain angle, so as to facilitate the purpose of driving the ear plate to rotate downward by opening the electric push rod two, thus ensuring the rationality of the structural design.

[0008] Furthermore, a guide rail is fixedly installed on the outer side of the HDR camera on the surface of the testing platform. The left and right ends of the HDR camera are slidably connected to the guide rail, and the guide rail limits the position of the HDR camera to ensure its stability during movement.

[0009] Furthermore, an electric push rod three is fixedly installed on the guide rail at the middle of the front end. The telescopic end of the electric push rod three is fixedly connected to the HDR camera. That is, after the optical lens tilts downward under the action of the electric push rod two, the HDR camera is moved backward by opening the electric push rod three, so that it can be kept in line with the optical lens and avoid deviation in the shooting image.

[0010] Furthermore, a display device is fixedly installed on the surface of the testing station near the right side, which allows staff to easily view the information.

[0011] The advantages of this utility model are as follows:

[0012] 1. Compared with traditional manual inspection, this device uses an HDR camera for inspection, which effectively avoids the influence of human eye fatigue and experience differences. During long-term inspection work, the HDR camera can always maintain stable inspection capabilities, ensuring the consistency and accuracy of inspection results. It can meet the needs of high-speed production, greatly improve inspection efficiency, and reduce human risks and costs, thus promoting the development of optical manufacturing towards automation and intelligence.

[0013] 2. Through the coordinated operation of electric push rod one, micro motor and electric push rod two, this device can not only drive the optical lens to rotate, but also make it rotate downwards at a certain angle. Under the illumination of the ring light source detection lamp, this multi-angle rotation can avoid missing local problems due to observation from a single angle, and at the same time magnify the tiny defects on the lens surface, making the detection more comprehensive and accurate, and effectively improving the detection accuracy and efficiency.

[0019] 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.

[0020] Please see Figures 1-4A high-precision inspection device for optical lens processing includes an inspection table 1. A mounting plate 2 is rotatably mounted on the back plate of the inspection table 1 near the center. A fixing ring 3 is fixedly connected to the center of the mounting plate 2. A filter 4 is fixedly connected to the lower end of the fixing ring 3. Electric push rods 5 are fixedly mounted on the front end of the mounting plate 2 near both the left and right sides. The telescopic ends of the electric push rods 5 pass through the fixing ring 3 and are fixedly connected to adapters 6. Rollers 7 are rotatably mounted inside the adapters 6. A double-ear connector 8 is fixedly connected to the inside of the fixing ring 3 near the rear end. A main roller 9 is rotatably mounted inside the double-ear connector 8. A rubber sleeve 10 is fixedly sleeved on the outside of the main roller 9. A ring light source detection lamp 14 is fixedly mounted on the back plate of the detection table 1 near the upper end. An HDR camera 15 is set on the table surface of the detection table 1 at the corresponding hanging ear plate 2. The upper shaft of the main roller 9 passes through the double-ear connector 8 and is fixedly sleeved with a worm gear 11. A micro motor 12 is fixedly mounted on the upper end of the hanging ear plate 2 near the rear side. A worm gear 13 is fixedly mounted on the front output end of the micro motor 12 through a coupling. The worm gear 13 is meshed with the worm gear 11. The optical lens to be inspected is placed on the filter 4. Then, two sets of symmetrical electric push rods 5 are activated to drive the adapter 6, which moves the roller 7. The movement of the roller 7 moves the optical lens until its rear end abuts against the rubber sleeve 10, thus completing the clamping and positioning of the optical lens and preventing slippage during subsequent inspection. At the same time, the micro motor 12 is activated to drive the worm gear 13 to rotate the worm wheel 11. The rotation of the worm wheel 11 drives the main roller 9 to rotate. Under the increased friction of the rubber sleeve 10, the rotation of the main roller 9 drives the optical lens to rotate. Under the uniform illumination of the ring light source inspection lamp 14, the rotation of the optical lens avoids missing local problems due to observation from a single angle. At the same time, the optical phenomena observed by rotation can more accurately judge the quality of the lens. Compared with traditional manual inspection, this device uses the HDR camera 15 to inspect the optical lens. Machine vision inspection is not affected by human eye fatigue or experience differences, meets the needs of high-speed production, can achieve high-precision and high-efficiency inspection of optical lenses, and can also reduce human risks and costs, promoting the development of optical manufacturing towards automation and intelligence.

[0021] Please see Figures 1-4An electric push rod 16 is rotatably mounted on the lower end of the ear plate 2 near the middle of the rear side. The lower end of the electric push rod 16 is rotatably mounted between the back plate of the detection table 1 and tilted backward at a certain angle. By opening the electric push rod 16, the ear plate 2 can be rotated downward. Thus, the rotation of the ear plate 2 can drive the optical lens that is clamped and positioned to rotate. When the ring light source detection lamp 14 illuminates the optical lens at a certain angle, the tiny defects on its surface will cause the light to scatter or reflect, forming obvious light spots or stripes, which magnifies the tiny defects on the lens surface, making the detection more efficient and accurate. It is worth mentioning that the filter 4 can not only support the optical lens, but also filter out unnecessary wavelength light that penetrates the lens and interferes with the HDR camera 15, thereby improving the image quality of the HDR camera 15.

[0022] Please see Figure 1 On the surface of the testing table 1, a guide rail 17 is fixedly installed on the outside of the HDR camera 15. The left and right ends of the HDR camera 15 are slidably connected to the guide rail 17. An electric push rod 3 18 is fixedly installed on the guide rail 17 at the front middle. The rear telescopic end of the electric push rod 3 18 is fixedly connected to the HDR camera 15. By opening the electric push rod 3 18, the HDR camera 15 can be moved backward, thereby matching it with the downward rotating optical lens. A display device 19 is fixedly installed on the surface of the testing table 1 near the right side. The testing data can be displayed and recorded through the display device 19.

[0023] Working principle: In use, the optical lens to be tested is first placed on the filter 4. Then, the two sets of symmetrical electric push rods 5 are turned on to drive the adapter 6, which moves the secondary roller 7. The movement of the secondary roller 7 drives the optical lens to move until its rear end abuts against the rubber sleeve 10, thus completing the clamping and positioning of the optical lens. At the same time, turning on the micro motor 12 drives the worm gear 13 to rotate the worm wheel 11. The rotation of the worm wheel 11 drives the main roller 9 to rotate. Thus, under the action of increased friction from the rubber sleeve 10, the rotation of the main roller 9 drives the optical lens to rotate, thereby creating a ring-shaped optical lens. Under the uniform illumination of the source detection lamp 14, rotating the optical lens can avoid missing local problems due to observation from a single angle. This device uses the HDR camera 15 to take pictures and detect the optical lens. Furthermore, by opening the electric push rod 16, the hanging plate 2 can be rotated downwards. Thus, the rotation of the hanging plate 2 can drive the optical lens that is clamped and positioned to rotate. When the ring light source detection lamp 14 illuminates the optical lens at a certain angle, the tiny defects on its surface will cause the light to scatter or reflect, forming obvious light spots or stripes, which magnifies the tiny defects on the lens surface.
