Description

Technical Field

[0001] This invention relates to the field of lens inspection technology, specifically to an optical lens thickness inspection device. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent the glass block from developing internal stress. After cooling, the glass block must be measured with optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. Larger optical lenses often also require corresponding thickness measuring devices for testing after processing.

[0003] When using current optical lens thickness testing devices, some components of the fixture or testing device may block parts of the lens when testing complex-shaped lenses. This makes it impossible to directly measure the thickness of these blocked areas. Even with some non-contact measurement methods, the thickness information of the blocked areas may not be accurately obtained due to optical path obstruction. Often, re-inspection may be required to ensure measurement accuracy, which affects both the yield of finished products and processing efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By adjusting the mechanism, the lens can be radially rotated within the semi-ring frame, allowing the clamped portion of the lens to rotate radially outward. This enables automatic dynamic detection of the lens, allowing for the detection of all positions on the lens, including areas originally blocked by the clamping mechanism. This provides complete and accurate lens thickness data, avoiding deviations in detection results caused by missing data in certain areas. It eliminates the need for multiple clamping operations or the use of various detection methods to compensate for blocked areas, saving detection time and labor costs, improving overall detection efficiency, and making the detection process smoother and more efficient. Furthermore, comprehensive and accurate detection allows for the timely detection of lens problems during production, preventing waste in subsequent processing due to undetected issues in blocked areas and reducing the scrap rate.

[0019] 2. Through the pick-and-place mechanism and the adjustment mechanism, qualified lenses can be transferred to the first discharge rack for delivery, and unqualified lenses can be transferred to the second discharge rack for delivery. During lens inspection, the lens transfer can be completed automatically, and the inspected lenses can also be automatically classified and transferred according to their quality. This facilitates continuous lens inspection and avoids the time and manpower problems caused by manual loading and unloading of single lenses. This allows the device to meet the industrial requirements of large-scale optical lens inspection.

[0020] 3. Through the covering mechanism and the support mechanism, it can automatically adapt to the curvature of the mirror surface when adsorbing and rotating the cover to fit the mirror surface, thereby completing the clamping of irregularly shaped lenses and avoiding the problem of uneven fitting causing the lens to tilt and affecting the accuracy of the test. At the same time, when the vacuum suction head loses its adsorption force on the lens and when the lens is rotated radially, the upper and lower matching air cloth cover and the covering arc plate can also support and limit the lens, ensuring stability and safety during radial rotation and preventing the lens from falling off and being damaged.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] To address the technical problems of low efficiency in manual loading and unloading and the inability to separate defective lenses, such as Figures 1-4 As shown, the following preferred technical solution is provided: an optical lens thickness detection device, including a work frame 1 and an adjustment mechanism 5 disposed on one side above the pick-and-place mechanism 4. The pick-and-place mechanism 4 is disposed in the upper middle part of the work frame 1. Two sets of detection heads 2 are disposed opposite each other on the upper and lower parts of the work frame 1. The two sets of detection heads 2 are existing laser thickness measurement probes, which are respectively a emitting light source and a receiving light source. A feeding rack 3 is disposed in the rear middle part of the work frame 1, a first discharge rack 8 is disposed in the front middle part of the work frame 1, and a second discharge rack 9 is disposed in the middle part of one side of the work frame 1. A control box 10 is installed on the upper side of the work frame 1. The feeding rack 3, the first discharge rack 8 and the second discharge rack 9 are all existing common conveyor belts. An electric slide rail is disposed between the detection head 2 and the work frame 1, which can move back and forth to detect the thickness of the lens from the middle to the edge.

[0034] The pick-and-place mechanism 4 includes a first motor 401 installed on one side below the work frame 1. A first synchronous pulley 402 is connected to one side of the first motor 401, and a rotating disk 403 is connected to the upper end of the first synchronous pulley 402. The rotating disk 403 is rotatably connected to the work frame 1 through the first synchronous pulley 402 and the first motor 401. A through hole 11 is provided in the middle of the rotating disk 403, through which light can pass through, so that the detection head 2 can detect the lens.

[0035] Mounting bases 404 are installed on both sides above the rotating disk 403, and a swing arm 405 is rotatably connected to one side of the mounting base 404. A second motor 406 is installed on the outer side of the swing arm 405, and a gap gear 407 is rotatably connected to the output end of the second motor 406. The convex teeth of the gap gear 407 are distributed at one-quarter of the outer surface. A lower mating wheel 408 with full convex teeth is provided below the gap gear 407. The swing arm 405 is rotatably connected to the mounting base 404 through the second motor 406, the gap gear 407, and the lower mating wheel 408.

[0036] A fully toothed upper mating wheel 409 is provided above the gap gear 407, and a second synchronous belt pulley 410 is rotatably connected to the upper rear part of the upper mating wheel 409. A rotating frame 411 is rotatably connected to the upper end of the second synchronous belt pulley 410. The gap gear 407 is rotatably connected to the rotating frame 411 through the upper mating wheel 409, the second synchronous belt pulley 410, and the lower mating wheel 408 and the mounting base 404 shaft, as well as the upper mating wheel 409 and the swing arm 405 shaft, are all made of spring steel with interference fit to ensure that the lower mating wheel 408 and the upper mating wheel 409 can remain non-rotating with the axial connection part without applying rotational force. The lens to be tested can be automatically moved and adjusted through the pick-and-place mechanism 4.

[0037] The second servo motor 406 drives the gap gear 407 to rotate counterclockwise, which in turn drives the lower mating wheel 408 to rotate 90 degrees clockwise. This causes the swing arm 405 and the mounting base 404 to rotate 90 degrees clockwise. After the subsequent adjustment mechanism 5 picks up the lens, the second motor 406 drives the gap gear 407 and the lower mating wheel 408 to rotate 90 degrees counterclockwise, causing the picked-up lens to be lifted vertically again by the swing arm 405. The upward clockwise rotation of the gap gear 407 drives the upper mating wheel 409, which, in conjunction with the second synchronous belt pulley 410, causes the rotating frame 411 to rotate 90 degrees counterclockwise. This allows the vertically lifted lens to be placed horizontally, with the lens positioned at the center of the detection head 2, facilitating the thickness measurement of the lens by the detection head 2. The first motor 401 and the first synchronous pulley 402 can drive the rotating disk 403 and its swing arm 405 to rotate clockwise by 90 degrees or 180 degrees after the inspection. When the lens thickness is qualified, the rotation is clockwise by 180 degrees. With the rotation of the swing arm 405 and the feeding of the adjustment mechanism 5, qualified lenses can be transferred to the first discharge rack 8 for delivery. When the thickness is unqualified, the rotation is clockwise by 90 degrees to transfer the unqualified lenses to the second discharge rack 9 for delivery. Therefore, during lens inspection, the transfer of lenses can be completed automatically. At the same time, the inspected lenses can be automatically classified and transferred according to their quality. This is conducive to continuous lens inspection and avoids the time and manpower problems caused by manual loading and unloading of single lenses. This allows the device to meet the industrial requirements of large-scale optical lens inspection.

[0038] To address the issue of inaccurately obtaining thickness information in obstructed areas due to optical path blockage, re-inspection is often required to ensure measurement accuracy. This presents a technical problem that impacts both finished product yield and processing efficiency. Figures 1-10 As shown, the following preferred technical solution is provided: the adjustment mechanism 5 includes an air distribution hood 501 installed on one side of the rotating frame 411, a vacuum suction head 502 is provided in the middle of the inner side of the air distribution hood 501, and a first air guide pipe 503 is connected to the rear surface of the air distribution hood 501, and a first solenoid valve 504 is provided in front of the first air guide pipe 503.

[0039] A semi-ring frame 505 is provided on the front side of the air distribution hood 501, and a piston chamber 506 is provided on the surface of the semi-ring frame 505. A second solenoid valve 507 is installed on the upper side of the piston chamber 506, and a second air guide pipe 508 is connected above the second solenoid valve 507. An air inlet 509 is connected to the outer front end of the piston chamber 506, and a piston plate 510 is provided in the middle of the inner side of the piston chamber 506. A connecting frame 511 is installed on one side of the piston plate 510, and an installation head 512 is fixed at one end of the connecting frame 511. A reduction motor 513 is installed in the middle of one side of the installation head 512, and a rolling wheel 514 is connected to the front end of the reduction motor 513.

[0040] The vacuum suction head 502 is connected to the first air guide tube 503 and the first solenoid valve 504 through the air distribution cover 501. The piston chamber 506 is arranged in four groups in a ring about the semi-ring frame 505. The piston chamber 506 is connected to the first air guide tube 503 through the second solenoid valve 507 and the second air guide tube 508. The piston plate 510 is slidably connected to the piston chamber 506 through the connecting frame 511. The reduction motor 513 is rotatably connected to the rolling wheel 514 through the mounting head 512. The first air guide tube 503 and the second air guide tube 508 are connected to the existing external vacuum pump. Through the adjustment mechanism 5, the adsorbed lens can be radially rotated and adjusted so that the lens can be fully inspected.

[0041] The air hood 501 and vacuum head 502 adhere to the surface of the lens when the swing arm 405 rotates downward. The second solenoid valve 507 closes and the first solenoid valve 504 opens, allowing the first air duct 503 to evacuate the vacuum head 502. At this time, the air hood 501 and vacuum head 502 can adsorb and fix the lens. After the lens is leveled by the pick-and-place mechanism 4 and closed by the cover mechanism 6, the first solenoid valve 504 closes and the second solenoid valve 507 opens. The suction force of the vacuum head 502 at the bottom of the horizontally positioned lens disappears. The second air duct 508 evacuates the piston chamber 506, causing the air inlet 509 to exert an inward pushing force on the piston plate 510 and connecting bracket 511, causing the connecting bracket 511 to drive the mounting head 512 and the rolling wheel 514. The inward movement causes the rolling wheels 514 within the multiple annularly distributed piston chambers 506 on the two semi-ring frames 505 to adhere to the side surface of the lens. Multiple small geared motors 513 drive the rolling wheels 514 to rotate synchronously, allowing the lens to rotate radially within the semi-ring frame 505. This, in turn, causes the clamped portion of the lens to rotate radially outward, enabling automatic dynamic detection of the lens. This allows for detection of all positions on the lens, including areas originally blocked by the suction clamp, resulting in complete and accurate lens thickness data. This avoids deviations in detection results caused by missing data in certain areas. It eliminates the need for multiple clamping operations or the use of various detection methods to compensate for blocked areas, saving detection time and labor costs, improving overall detection efficiency, and making the detection process smoother and more efficient.

[0042] To address the technical challenges of clamping irregularly shaped lenses and ensuring lens stability and safety during adjustment, such as... Figures 5-7 as well as Figure 10 As shown, the following preferred technical solution is provided: A cover mechanism 6 is provided on one side of the adjustment mechanism 5. The cover mechanism 6 includes a rotating plate 601 connected to one side of the air distribution hood 501. One end of the rotating plate 601 is connected to a rotating shaft 602, and a rotating motor 603 is installed below the rotating shaft 602. The rotating plate 601 is rotatably connected to the air distribution hood 501 through the rotating motor 603 and the rotating shaft 602. A cover arc plate 604 is fixed to the other end of the rotating plate 601. An elastic column 605 is installed on the inner surface of the cover arc plate 604, and a first ball bearing 606 is provided on the front surface of the elastic column 605. The elastic column 605 is elastically connected to the cover arc plate 604 by a spring at its inner bottom.

[0043] The adjustment mechanism 5 is provided with a support mechanism 7 in the middle. The support mechanism 7 includes a folded tube 701 located behind the vacuum suction head 502. A support cover 702 is provided at the front end of the folded tube 701. A second ball bearing 703 is provided on the front surface of the support cover 702. Both the first ball bearing 606 and the second ball bearing 703 are provided with a smooth rubber outer layer, which can prevent wear and facilitate the radial rotation of the lens after it is covered. Through the covering mechanism 6 and the support mechanism 7, the irregularly shaped lens can be clamped. At the same time, the lens can be kept stable during lens adjustment to prevent the lens from falling off.

[0044] By rotating the motor 603 and the rotating shaft 602, the rotating plate 601 and the covering arc plate 604 are driven to rotate. After the air cover 501 adsorbs the lens and when rotating to adjust the level, the covering arc plate 604 can cover the upper part of the lens. Through the deformability of the folding tube 701 and the elastic compression deformation of the elastic column 605, it can automatically adapt to the curvature of the lens when adsorbing and rotating to cover and fit the lens, thereby completing the clamping of irregularly shaped lenses and avoiding the problem of uneven fitting causing the lens to tilt and affecting the accuracy of detection. At the same time, when the adsorption force of the vacuum suction head 502 on the lens disappears and when the lens is rotated radially, the upper and lower aligned air cover 501 and the covering arc plate 604 can also support and limit the lens, ensuring stability and safety during radial rotation and preventing the lens from falling off and being damaged.
