Description

Technical Field

[0001] This invention belongs to the field of optical inspection, specifically relating to an optical lens surface precision inspection device based on a new material. Background Technology

[0002] In traditional optical lens inspection equipment, the inspection optical path and the lens placement plate are mostly adjusted independently, which can easily lead to problems such as focusing lag and relative position shift. When using a single height adjustment, the lens is prone to deviating from the center of the optical path, resulting in unstable reflected light signals and blurred imaging, making it difficult to meet the high-precision inspection requirements of new material lenses. By moving the optical inspection instrument and the lens placement plate up and down synchronously, a constant inspection spacing and incident angle can be maintained, reducing focusing errors and vibration interference, improving inspection stability and accuracy, and making it more suitable for the inspection characteristics of new material lenses, which are thin, easily deformable, and have high surface requirements.

[0003] Patent CN217688510U discloses an optical lens surface precision testing device, which includes a body with a testing stage sliding vertically on the body. The body has a testing component for testing Newton's rings on the optical lens. A rotating rod is rotatably mounted on the testing stage, and a first driving assembly is provided on the testing stage to drive the rotating rod to rotate. Connecting plates are fixedly mounted on both sides of the rotating rod, and sliders are slidably mounted on both connecting plates vertically. A second driving assembly is provided on the connecting plates to drive the sliders to slide. An adsorption assembly for adsorbing optical lenses is provided on the sliders. The optical lenses are adsorbed by the adsorption assemblies on the two connecting plates, and the first driving assembly drives the rotating rod to rotate the adsorption assembly, enabling continuous feeding of optical lenses onto the testing stage, thus improving testing efficiency.

[0004] However, during the use of the above-mentioned device, it is difficult to synchronize the optical inspection precision instrument with the optical lens in terms of vertical displacement adjustment. This can easily lead to phenomena such as defocusing and spot distortion, which affect the accuracy of optical lens precision detection, and thus affect the accuracy and efficiency of the device in detecting the surface precision of optical lenses. Summary of the Invention

[0005] The purpose of this invention is to provide an optical lens surface accuracy detection device based on new materials, so as to solve the problems of defocus and spot distortion that easily occur during the surface accuracy detection of optical lenses.

[0006] To achieve the above objectives, this invention provides an optical lens surface precision inspection device based on a new material, comprising a control base, an electric slide rail mounted on the control base, an optical inspection precision instrument mounted on the electric slide rail, a control panel mounted on the optical inspection precision instrument, an electric telescopic rod mounted on the control base, a vertical slide rail I mounted on the control base, a movable plate fixedly connected to the telescopic end of the electric telescopic rod, a guide ramp mounted on the vertical slide rail I, a sliding column I fixedly connected to the right side of the movable plate, an elastic telescopic rod I fixedly connected to the inner wall of the movable plate, a fixed block fixedly connected to the telescopic end of the elastic telescopic rod I, and a sliding column II fixedly connected to the inner wall of the fixed block. This allows the electric slide rail to drive the optical inspection precision instrument to move synchronously up and down, maintaining the standard working distance between the lens and the optical inspection precision instrument's detection optical path, thus avoiding defocus and light spots. Distortion is eliminated, facilitating clear imaging. Synchronous adjustment eliminates repeated focusing steps, significantly improving optical detection efficiency, ensuring stable incident light angle, and enhancing the repeatability and accuracy of surface precision detection for new material optical lenses. A roller is rotatably connected to the inner wall of the sliding column two. An elastic telescopic rod two is fixedly connected to the right side of the sliding column two. A limit plate is fixedly connected to the telescopic end of the elastic telescopic rod two. A vertical slide rail two is installed on the moving plate. A slider is slidably connected to the inner wall of the vertical slide rail two. A connecting rod one is rotatably connected to the inner wall of the slider. An L-rod is fixedly connected to the bottom of the slider. A placement plate is fixedly connected to the inner wall of the L-rod. This improves the detection accuracy and efficiency of the device. The limit plate can center and fix the L-rod during lateral movement, quickly and automatically aligning the lens to the center of the optical path, reducing reflected light offset and uneven imaging caused by eccentricity, and achieving rapid lens attitude calibration.

[0007] In one possible implementation, the inner wall of the guide ramp is provided with a light-shielding mechanism for detecting light blocking, and the inner wall of the light-shielding mechanism is provided with a supplementary light mechanism for detecting supplementary light. The first sliding column is slidably connected to the inner wall of the first vertical slide. The roller is in contact with the guide ramp, and the guide ramp is used to push the roller to move in the opposite direction. The second sliding column is in contact with the moving plate. This eliminates the need for manual adjustment, improves optical detection efficiency, provides gentle positioning contact, is less likely to scratch the lens surface, ensures the authenticity of the detected surface shape, and improves the accuracy and consistency of surface precision detection.

[0008] In one possible implementation, the connecting rod one is rotatably connected to the inner wall of the sliding column two, and the sliding column two is used to drive the connecting rod one to move and rotate. The L rod is in contact with the moving plate, and the placement plate is in contact with the moving plate. During the process of the roller rising, the guide plate will press in the opposite direction and push the roller to move laterally. The lateral movement of the roller will drive the sliding column two to move synchronously. During the movement of the sliding column two, the sliding column two will drive the elastic telescopic rod two to move.

[0009] In one possible implementation, the light-shielding mechanism includes a second connecting rod, which is fixedly connected to the front of the placement plate. The inner wall of the second connecting rod is rotatably connected to a first hinge plate via a torsion spring. After the first reflector rotates, it can reflect the side of the lens, allowing the operator to more intuitively observe the fineness of the lens side and increasing the accuracy detection effect of the lens side. This improves the accuracy and comprehensiveness of the device's lens detection. The inner wall of the first hinge plate is fixedly connected to the first reflector.

[0010] In one possible implementation, the light-shielding mechanism further includes a fixed groove rod, which is fixedly connected to the inner wall of the guide inclined plate. A light-shielding plate is fixedly connected to the inner wall of the fixed groove rod. The light-shielding plate can shield the detection area of ​​the placement plate, isolating the detection area from strong external light. The inner wall of the light-shielding plate is slidably connected to the light-shielding plate, and a guide column is fixedly connected to the front of the light-shielding plate. This ensures that the optical inspection precision instrument's own detection light source is not interfered with by strong external light during the detection process, effectively improving the accuracy of the device and enhancing the detection precision.

[0011] In one possible implementation, the hinge plate one is in contact with the movable plate, and the movable plate is used to rotate and limit the hinge plate one. The reflector one is in contact with the movable plate. The guide post is located on the movement trajectory of the sliding post two, and the sliding post two is used to push the guide post upward. After the sliding post two moves and rises a certain distance, the sliding post two will contact the guide post and squeeze and push the guide post upward. The rise of the guide post will drive the light-shielding plate two to move and rise.

[0012] In one possible implementation, the supplementary lighting mechanism includes a three-section elastic telescopic rod, which is fixedly connected to the top of a light-shielding plate. An L-shaped block is fixedly connected to the telescopic end of the three-section elastic telescopic rod, and a connecting column is fixedly connected to the inner wall of the L-shaped block. A second hinge plate can then be reset and rotated via its own torsion spring. This reset and rotation of the second hinge plate will cause the supplementary lighting module to rotate. After rotating a certain angle, the supplementary lighting module will tilt and align the light source angle with the lens detection area, enabling supplementary lighting operations on the detection area. The circumferential surface of the connecting column is rotatably connected to the second hinge plate via a torsion spring. The inner wall of the second hinge plate is equipped with the supplementary lighting module, which can cooperate with an optical inspection precision instrument for precision testing, avoiding detection blind spots caused by light source issues, and improving the detection authenticity and accuracy of the device.

[0013] In one possible implementation, the supplementary lighting mechanism further includes a connecting groove plate, which is fixedly connected to the inner wall of the limiting plate. The inner wall of the connecting groove plate is rotatably connected to a mounting plate via a torsion spring. A second reflector is fixedly connected to the inner wall of the mounting plate. The mounting plate can map a portion of the side of the new material optical lens onto itself, allowing for a more intuitive observation of the precision of the side of the new material optical lens, improving the accuracy detection effect of the device, and achieving diversified detection.

[0014] In one possible implementation, the second hinge plate contacts the fixed groove rod, and the fixed groove rod is used to reset and limit the second hinge plate. The L block is located on the movement trajectory of the second light-shielding plate, and the second light-shielding plate is used to push the L block to rise. During the positioning and clamping of the new material optical lens, the limiting plate will synchronously drive the connecting groove plate to move. The movement of the connecting groove plate will drive the mounting plate to move, and the movement of the mounting plate will drive the second reflector to move.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This optical lens surface precision inspection device based on new materials, through the coordinated movement of the control base, electric slide rail, optical inspection precision instrument, electric telescopic rod, vertical slide rail one, moving plate, guide inclined plate, slide column one, elastic telescopic rod one, fixed block, slide column two, roller, elastic telescopic rod two, limit plate, vertical slide rail two, slider, connecting rod one, L rod, and placement plate, enables the electric slide rail to drive the optical inspection precision instrument to move up and down synchronously. This maintains the standard working distance between the lens and the optical inspection precision instrument's detection optical path, avoiding defocus and spot distortion, facilitating clear imaging, and saving time and effort in synchronous adjustment. By eliminating repeated focusing steps, optical inspection efficiency is greatly improved, the incident light angle is kept stable, and the repeatability and accuracy of surface precision inspection of new material optical lenses are enhanced. This improves the inspection accuracy and efficiency of the device. The limiting plate can center and fix the L-rod during lateral movement, which can quickly and automatically align the lens with the center of the optical path, reduce reflected light offset and imaging unevenness caused by eccentricity, achieve rapid lens posture calibration, eliminate manual adjustment, improve optical inspection efficiency, and the positioning contact is gentle and does not easily scratch the lens surface, ensuring the authenticity of the inspection surface shape and improving the accuracy and consistency of surface precision inspection. 2. This optical lens surface precision inspection device based on new materials, through the coordinated movement of connecting rod 2, hinge plate 1, reflector 1, fixed groove rod, light shield 1, light shield 2, and guide column, enables reflector 1 to reflect the side of the lens, allowing operators to more intuitively observe the fineness of the lens side, while increasing the precision inspection effect of the lens side, thus improving the device's precision inspection effect and comprehensiveness. Light shield 2 can block the inspection of the placement plate, isolating the inspection area from strong external light, ensuring that the optical inspection precision instrument's own inspection light source is not affected by strong external light during the inspection process, effectively improving the device's precision inspection effect and enhancing the inspection accuracy. 3. This optical lens surface precision inspection device based on new materials utilizes the coordinated movement of three elastic telescopic rods, an L-block, a connecting column, a hinge plate, a supplementary lighting module, a connecting slot plate, a mounting plate, and a reflector. After rotating a certain angle, the supplementary lighting module tilts, aligning the light source with the lens inspection area. This allows for supplementary lighting of the inspection area and enables precision inspection in conjunction with an optical inspection precision instrument. It avoids blind spots caused by light source issues, improving the device's inspection accuracy and reliability. The mounting plate can project a portion of the side surface of the new material optical lens onto itself, allowing for more direct observation of the lens's side precision, further enhancing the device's precision inspection effect and enabling diversified inspection capabilities.

[0018] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0019] like Figures 1-10 As shown, one embodiment of the present invention is: an optical lens surface precision testing device based on a new material, comprising a control base 1, an electric slide rail 2 mounted on the control base 1, an optical inspection precision instrument 3 mounted on the electric slide rail 2, a control panel mounted on the optical inspection precision instrument 3, an electric telescopic rod 4 mounted on the control base 1, a vertical slide rail 5 mounted on the control base 1, a movable plate 6 fixedly connected to the telescopic end of the electric telescopic rod 4, a guide inclined plate 7 mounted on the vertical slide rail 5, a sliding column 10 fixedly connected to the right side of the movable plate 6, and an elastic telescopic rod 11 fixedly connected to the inner wall of the movable plate 6. A fixed block 12 is fixedly connected to the telescopic end of the elastic telescopic rod 11. A sliding column 13 is fixedly connected to the inner wall of the fixed block 12. A roller 14 is rotatably connected to the inner wall of the sliding column 13. An elastic telescopic rod 15 is fixedly connected to the right side of the sliding column 13. A limit plate 16 is fixedly connected to the telescopic end of the elastic telescopic rod 15. A vertical slide rail 17 is installed on the movable plate 6. A slider 18 is slidably connected to the inner wall of the vertical slide rail 17. A connecting rod 19 is rotatably connected to the inner wall of the slider 18. An L-rod 20 is fixedly connected to the bottom of the slider 18. A placement plate 21 is fixedly connected to the inner wall of the L-rod 20. When the device is preparing to perform precision testing on the surface of a new material optical lens, the operator first places the new material optical lens in the testing area of ​​the placement plate 21. After the preparation is completed, the electric telescopic rod 4 will be activated. The telescopic end of the electric telescopic rod 4 will drive the moving plate 6 to rise. During the rising process, the moving plate 6 will drive the sliding column 10 to rise. The sliding column 10 will slide smoothly up and down on the inner wall of the vertical slide rail 5. At the same time, the rising of the moving plate 6 will also drive the placement plate 21 to rise. During the rising process, the placement plate 21 will synchronously drive the new material optical lens to rise. At the same time, during the rising process of the new material optical lens, the electric slide rail 2 will drive the optical inspection precision instrument 3 to move up and down synchronously. This can always maintain the standard working distance of the detection optical path between the lens and the optical inspection precision instrument 3, avoid defocus and spot distortion, facilitate clear imaging, and eliminate repeated focusing steps through synchronous adjustment, greatly improve the optical detection efficiency, ensure the stability of the incident light angle, improve the repeatability and accuracy of the surface precision testing of the new material optical lens, and improve the detection accuracy and efficiency of the device. The inner wall of the guide ramp 7 is provided with a light-blocking mechanism 8 for detecting light blocking, and the inner wall of the light-blocking mechanism 8 is provided with a light-filling mechanism 9 for detecting supplementary light. The first slide column 10 is slidably connected to the inner wall of the first vertical slide rail 5. The roller 14 is in contact with the guide ramp 7, and the guide ramp 7 is used to push the roller 14 to move in the opposite direction. The second slide column 13 is in contact with the moving plate 6. The first connecting rod 19 is rotatably connected to the inner wall of the second slide column 13, and the second slide column 13 is used to drive the first connecting rod 19 to move and rotate. The L rod 20 is in contact with the moving plate 6, and the placement plate 21 is in contact with the moving plate 6. As the moving plate 6 rises, it moves the vertical slide rail 17, and simultaneously moves the elastic telescopic rod 11. The movement of the elastic telescopic rod 11 moves the fixed block 12, which in turn moves the sliding column 13. The rising of the sliding column 13 then moves the roller 14. During this rise, the roller 14 contacts the inclined surface of the guide plate 7. At this time, the guide plate 7, while the roller 14 is rising, reverses and pushes it to move laterally. This lateral movement of the roller 14 causes the sliding column 13 to move synchronously. During this movement, the sliding column 13 moves the elastic telescopic rod 15, which in turn moves the limiting plate 16 closer to the new material optical lens. Simultaneously, during this movement, the sliding column 13 moves the connecting rod 19. Due to the angular difference between the connecting rod 19 and the sliding column 13, the connecting rod 19 will move and rotate due to the angular difference during the movement. The rotation of the connecting rod 19 will simultaneously drive the slider 18 to rise. The rise of the slider 18 will drive the L-rod 20 to rise. The rise of the L-rod 20 will drive the placement plate 21 to rise. The rise of the placement plate 21 will drive the new material optical lens to rise. After the placement plate 21 rises a certain distance, the L-rod 20 will gradually be on the same horizontal plane as the limiting plate 16. The limiting plate 16 can center and fix the L-rod 20 during the lateral movement, which can quickly and automatically align the lens with the center of the optical path, reduce the reflected light offset and imaging unevenness caused by eccentricity, realize the rapid calibration of the lens posture, eliminate manual adjustment, improve the optical detection efficiency, and the positioning contact is soft and does not easily scratch the lens surface, ensuring the authenticity of the detection surface shape and improving the accuracy and consistency of surface precision detection.

[0020] Overall working principle: The electric slide rail 2 drives the optical inspection precision instrument 3 to move up and down synchronously, which can always maintain the standard working distance between the lens and the optical inspection precision instrument 3, avoiding defocus and light spot distortion, facilitating clear imaging. Synchronous adjustment eliminates repeated focusing steps, greatly improving optical inspection efficiency, ensuring stable incident light angle, improving the repeatability and accuracy of surface precision inspection of new material optical lenses, and improving the detection accuracy and efficiency of the device. It can quickly and automatically align the lens with the center of the optical path, reducing reflected light offset and uneven imaging caused by deflection, realizing rapid lens posture calibration, eliminating manual adjustment, improving optical inspection efficiency, and the positioning contact is gentle and does not easily scratch the lens surface, ensuring the authenticity of the inspection surface shape and improving the accuracy and consistency of surface precision inspection.

[0021] like Figures 1-10As shown, based on the above embodiments, in another embodiment of the present invention, the light-shielding mechanism 8 includes a second connecting rod 801, which is fixedly connected to the front of the placement plate 21. The inner wall of the second connecting rod 801 is rotatably connected to a first hinge plate 802 via a torsion spring, and the inner wall of the first hinge plate 802 is fixedly connected to a first reflector 803. When the device is in use, as the placement plate 21 rises, it simultaneously drives the connecting rod 801 to rise as well. The rise of the connecting rod 801 drives the hinge plate 802 to rise, which in turn drives the reflector 803 to move upwards. During this upward movement, the reflector 803 and the hinge plate 802 come into contact with the moving plate 6. The moving plate 6 then limits the movement of the hinge plate 802 as it rises, causing the hinge plate 802 to move upwards. During the process, the mirror rotates synchronously, causing the reflector 803 to rotate synchronously as well. When the moving plate 6 is no longer in contact with the hinge plate 802, the hinge plate 802 will rotate and reset through its own torsion spring, causing the reflector 803 to rotate and reset synchronously. After the reflector 803 has rotated to the desired angle, it can reflect the side of the lens, allowing the operator to observe the fineness of the lens side more intuitively. This also increases the accuracy detection effect of the lens side, improving the accuracy and comprehensiveness of the device for lens detection. The light-shielding mechanism 8 also includes a fixed groove rod 804, which is fixedly connected to the inner wall of the guide inclined plate 7. A light-shielding plate 805 is fixedly connected to the inner wall of the fixed groove rod 804. A light-shielding plate 806 is slidably connected to the inner wall of the light-shielding plate 805. A guide post 807 is fixedly connected to the front of the light-shielding plate 806. A hinge plate 802 is in contact with the moving plate 6, and the moving plate 6 is used to rotate and limit the hinge plate 802. A reflector 803 is in contact with the moving plate 6. The guide post 807 is located on the movement trajectory of the sliding post 13, and the sliding post 13 is used to push the guide post 807 to rise. During use, after sliding column 13 moves and rises a certain distance, it will contact guide column 807 and push guide column 807 to rise. The rise of guide column 807 will drive light shield 806 to move and rise. After rising a certain distance, light shield 806 will gradually be above light shield 805. At this time, light shield 806 can block the light from the detection of the placement plate 21, and can isolate the detection area from strong external light. This ensures that the optical inspection precision instrument 3 is not affected by strong external light during the detection process, which can effectively improve the accuracy of the device and enhance the detection precision. The supplementary lighting mechanism 9 includes an elastic telescopic rod 901, which is fixedly connected to the top of the light-shielding plate 805. An L-block 902 is fixedly connected to the telescopic end of the elastic telescopic rod 901. A connecting column 903 is fixedly connected to the inner wall of the L-block 902. A hinge plate 904 is rotatably connected to the circumferential surface of the connecting column 903 via a torsion spring. A supplementary lighting module 905 is provided on the inner wall of the hinge plate 904. When the device is in use, after the second light-shielding plate 806 rises a certain distance, it contacts and presses against the L-block 902, pushing it upwards. Before rising, the L-block 902 preferentially transmits its pushing force to the third elastic telescopic rod 901, causing it to stretch. This stretching of the elastic telescopic rod 901 causes the L-block 902 to rise. The rise of the L-block 902 then causes the connecting column 903 to rise synchronously. The movement of the connecting column 903 causes the second hinge plate 904 to rise, and simultaneously, the second hinge plate 904 causes the supplementary lighting module 905 to rise. After rising a certain distance... Afterwards, the hinge plate 904 will no longer be in contact with the fixed groove rod 804. At this time, the limitation of the fixed groove rod 804 on the hinge plate 904 will be released, and the hinge plate 904 can be reset and rotated by its own torsion spring. The reset and rotation of the hinge plate 904 will drive the supplementary light module 905 to rotate. After rotating a certain angle, the supplementary light module 905 will tilt and align the light source angle with the lens detection area, which can perform supplementary lighting operation on the detection area. It can cooperate with the optical inspection precision instrument 3 to perform precision detection, avoid detection blind spots caused by light source problems, and improve the detection authenticity and accuracy of the device. The supplementary lighting mechanism 9 also includes a connecting slot plate 906, which is fixedly connected to the inner wall of the limiting plate 16. The inner wall of the connecting slot plate 906 is rotatably connected to the mounting plate 907 via a torsion spring. The inner wall of the mounting plate 907 is fixedly connected to the second reflector 908. The second hinge plate 904 is in contact with the fixed slot rod 804, and the fixed slot rod 804 is used to reset and limit the second hinge plate 904. The L block 902 is located on the movement trajectory of the second light-shielding plate 806, and the second light-shielding plate 806 is used to push the L block 902 to rise. When the device is in use, during the positioning and clamping process of the new material optical lens, the limiting plate 16 will simultaneously drive the connecting groove plate 906 to move. The movement of the connecting groove plate 906 will drive the mounting plate 907 to move, and the movement of the mounting plate 907 will drive the second reflector 908 to move. After moving a certain distance, the second reflector 908 can approach the side of the new material optical lens. At this time, the mounting plate 907 can map a part of the side of the new material optical lens onto itself, which can more intuitively observe the accuracy of the side of the new material optical lens, improve the accuracy detection effect of the device, and realize diversified detection.

[0022] Overall working principle: This allows operators to more intuitively observe the fineness of the lens side, while also increasing the accuracy of lens side detection. It enhances the device's accuracy and comprehensiveness in lens detection. The second light-shielding plate 806 shields the detection area of ​​the placement plate 21, isolating the detection area from strong external light. This ensures that the optical inspection precision instrument 3's own detection light source is not interfered with by strong external light during the detection process, effectively improving the device's accuracy and precision. The reset rotation of the second hinge plate 904 causes the supplementary light module 905 to rotate. After rotating a certain angle, the supplementary light module 905 tilts, aligning the light source with the lens detection area, providing supplementary lighting. This works in conjunction with the optical inspection precision instrument 3 for accuracy detection, avoiding detection blind spots caused by light source issues, and improving the device's detection authenticity and accuracy. The mounting plate 907 projects a portion of the side of the new material optical lens onto itself, allowing for more intuitive observation of the lens side's precision, further enhancing the device's accuracy and enabling diversified detection.
