Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of new material optical product detection, and specifically relates to an optical detection tooling. Background Art
[0002] When new material optical lenses such as modified polyurethane optical material lenses in optical elements are being produced and processed, various detections need to be carried out on them to ensure that the optical elements are accurate enough after being officially put into use. When detecting optical elements, they are often clamped and position-corrected through detection tooling.
[0003] When the existing detection tooling clamps the optical elements to be detected, generally, the optical lens is placed in the limit groove on its surface, and then clamped through the clamping structure. However, for modified polyurethane optical material lenses with a relatively thin thickness, it is often difficult to take them out of the limit groove after the detection is completed, and a specific blanking tool such as a suction cup is required to complete the material taking. Other clamping and supporting types of blanking tools are often difficult to carry out blanking.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an optical detection tooling is proposed. Summary of the Invention
[0005] Aiming at the deficiencies of the prior art, the present invention provides an optical detection tooling, which solves the problems put forward in the above background art.
[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: An optical detection tooling includes a tooling table and a lifting material loading mechanism. A circular hole is opened in the middle of the top surface of the tooling table, and a first limit groove is opened on the inner side surface of the circular hole. The lifting material loading mechanism is arranged inside the first limit groove. The lifting material loading mechanism includes a first movable ring, an outer ring plate, a second limit groove, a second movable ring, an inner ring plate, a third limit groove, a third movable ring, a central plate, and an electric telescopic rod. The inner side surface of the first movable ring is fixed with the outer ring plate, and a second limit groove is opened on the inner side surface of the outer ring plate. The second movable ring is arranged inside the second limit groove, and the inner side surface of the second movable ring is fixed with the inner ring plate. A third limit groove is opened on the inner side surface of the inner ring plate, and the third movable ring is arranged inside the third limit groove. The inner side surface of the third movable ring is fixed with the central plate, and the bottom of the central plate is fixed with the electric telescopic rod. An optical lens is placed on the surfaces of the outer ring plate, the inner ring plate, and the central plate. An optical detection device is arranged directly above the tooling table.
[0007] Furthermore, the bottom of the electric telescopic rod is fixed to the bottom of the inner wall of the tooling table, and the vertical central axis of the electric telescopic rod coincides with the vertical central axes of the outer ring plate, the inner ring plate, and the central plate.
[0008] Furthermore, movable balls are embedded in the surfaces of the outer ring plate and the inner ring plate, and a clamping and calibration mechanism is provided on one side of the electric telescopic rod inside the workbench.
[0009] Furthermore, the clamping calibration mechanism includes an oil pipe, an electric piston push rod and a shunt pipe, one end of the oil pipe is penetrated by the electric piston push rod, and the other end of the oil pipe is connected to the shunt pipe.
[0010] Furthermore, one end of the diverter pipe away from the oil pipe is divided into four branch pipes, and the end of each branch pipe passes through the top of the tooling table.
[0011] Furthermore, the clamping calibration mechanism also includes an electronic valve and a transmission tube. The end of the branch tube is connected to the electronic valve, and the side of the electronic valve away from the branch tube is connected to the transmission tube.
[0012] Furthermore, the clamping calibration mechanism also includes a piston rod, and the piston rod is passed through one end of the transmission tube away from the electronic valve.
[0013] Furthermore, the clamping calibration mechanism also includes a clamping plate, and the clamping plate is fixed to one end of the piston rod away from the transmission tube.
[0014] Furthermore, the clamping calibration mechanism also includes a laser distance measuring sensor, the surface of the clamping plate is embedded with the laser distance measuring sensor, and the end of the laser distance measuring sensor is flush with the surface of the clamping plate.
[0015] Furthermore, there are four laser distance measuring sensors in total, and the laser distance measuring sensors and the clamping plates are distributed one to one, and the two laser distance measuring sensors arranged relatively to each other are staggered with one being high and the other being low.
[0016] The present invention provides an optical inspection tool, which has the following beneficial effects:
[0017] 1. The optical inspection tooling, the electric telescopic rod is extended to make the center plate, inner ring plate and outer ring plate gradually rise to form a pagoda-shaped structure with the surface of the tooling table, so that the center plate, inner ring plate, outer ring plate and the tooling table form a stepped distribution from top to bottom. At this time, the center plate supports the center of the bottom of the optical lens, so that the optical lens is stably lifted to leave the annular limit groove, and the side of the optical lens is completely exposed at this time, so as to facilitate the U-shaped pallet to carry and transfer the optical lens, or the clamping mechanism to clamp and transfer the optical lens, thereby greatly reducing the difficulty of unloading the optical lens after inspection, and at the same time widely adapting to different material picking, unloading or transfer mechanisms.
[0018] 2. The optical detection tooling fixture clamps the optical lens from all angles. When the clamping plates extend, two relatively distributed laser distance sensors are arranged in a staggered manner with one higher and the other lower. The laser distance sensors continuously monitor the distance between the two clamping plates. When the distance dimension shrinks to the pre-input diameter dimension of the optical lens, the solenoid valve closes the transmission pipes corresponding to these two laser distance sensors. Thus, when the distance dimensions monitored by the two groups of relatively distributed laser distance sensors are consistent with the diameter dimension of the optical lens, it indicates that the position adjustment and calibration of the optical lens are completed and the clamping is also completed simultaneously. Moreover, since the extension distance of the clamping plates is precisely controlled, the optical lens can be prevented from being deformed due to excessive force. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0025] The following further describes in detail the embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0026] As Figures 1-5As shown in the figure, the present invention provides a technical solution: an optical detection tooling, including a tooling table 1 and a lifting and loading mechanism 4. A circular hole 2 is opened in the middle of the top surface of the tooling table 1, and a first limiting groove 3 is opened on the inner side surface of the circular hole 2. The lifting and loading mechanism 4 is arranged inside the first limiting groove 3. The lifting and loading mechanism 4 includes a first movable ring 401, an outer ring plate 402, a second limiting groove 403, a second movable ring 404, an inner ring plate 405, a third limiting groove 406, a third movable ring 407, a central plate 408 and an electric telescopic rod 409. The outer ring plate 402 is fixed to the inner side surface of the first movable ring 401, and a second limiting groove 403 is opened on the inner side surface of the outer ring plate 402. The second movable ring 404 is arranged inside the second limiting groove 403, and the inner ring plate 405 is fixed to the inner side surface of the second movable ring 404. A third limiting groove 406 is opened on the inner side surface of the inner ring plate 405, and the third movable ring 407 is arranged inside the third limiting groove 406. The central plate 408 is fixed to the inner side surface of the third movable ring 407, and the electric telescopic rod 409 is fixed to the bottom of the central plate 408. Optical lenses 5 are placed on the surfaces of the outer ring plate 402, the inner ring plate 405 and the central plate 408. An optical detection device 8 is arranged directly above the tooling table 1. The bottom of the electric telescopic rod 409 is fixed to the bottom of the inner wall of the tooling table 1, and the vertical central axis of the electric telescopic rod 409 coincides with the vertical central axes of the outer ring plate 402, the inner ring plate 405 and the central plate 408;
[0027] The specific operation is as follows: Place the optical lens 5 to be detected in the circular limiting groove on the surface of the tooling table 1. At this time, the electric telescopic rod 409 is in a contracted state, so that the central plate 408, the inner ring plate 405, the outer ring plate 402 are flush with the surface of the tooling table 1. Then use the clamping and calibration mechanism 7 to adjust and correct the position of the optical lens 5 and clamp it. At this time, the center of the optical lens 5 must coincide with the center of the central plate 408. Then move the tooling table 1 to carry the optical lens 5 to the detection position, and the optical detection device 8 detects the optical lens 5;
[0028] When the optical lens 5 needs to be removed after the detection is completed, the clamping calibration mechanism 7 first releases the clamping of the optical lens 5, and then the electric telescopic rod 409 is steadily extended to push the center plate 408 to rise. At this time, the third movable ring 407 rises with the center plate 408 along the inside of the third limiting groove 406. When the third movable ring 407 rises to the top of the third limiting groove 406, it will drive the inner ring plate 405 to rise. At this time, the second movable ring 404 rises with the inner ring plate 405 along the inside of the second limiting groove 403. When the second movable ring 404 rises to the top of the second limiting groove 403, it will drive the outer ring plate 402 to rise. At this time, the first movable ring 401 rises with the outer ring plate 402 along the inside of the first limiting groove 3 until the first movable ring 4 01 reaches the top of the first limit groove 3, and the electric telescopic rod 409 stops extending. At this time, the center plate 408, the inner ring plate 405, the outer ring plate 402 and the surface of the workbench 1 form a pagoda-shaped structure, so that the center plate 408, the inner ring plate 405, the outer ring plate 402 and the workbench 1 form a stepped distribution from top to bottom. At this time, the center plate 408 supports the center of the bottom of the optical lens 5, so that the optical lens 5 is stably lifted to leave the annular limit groove, and at this time, the side of the optical lens 5 is completely exposed, so as to facilitate the U-shaped pallet to carry and transfer the optical lens 5, or the clamping mechanism to clamp and transfer the optical lens 5, thereby greatly reducing the difficulty of unloading the optical lens 5 after detection, and at the same time widely adapting to different material collection, unloading or transfer mechanisms.
[0029] like Figures 1-5 As shown, the surfaces of the outer ring plate 402 and the inner ring plate 405 are embedded with movable balls 6, and a clamping calibration mechanism 7 is arranged on one side of the electric telescopic rod 409 inside the tooling table 1. The clamping calibration mechanism 7 includes an oil pipe 701, an electric piston push rod 702 and a shunt pipe 703. The electric piston push rod 702 is passed through one end of the oil pipe 701, and the other end of the oil pipe 701 is connected to the shunt pipe 703. The end of the shunt pipe 703 away from the oil pipe 701 is divided into four branches, and the end of each branch runs through the top of the tooling table 1. The clamping calibration mechanism 7 also includes an electronic valve 704 and a transmission pipe 705. The end of the branch pipe is connected to the electronic valve 704, and the side of the electronic valve 704 away from the branch pipe is connected to The transmission tube 705, the clamping calibration mechanism 7 also includes a piston rod 706, the piston rod 706 is penetrated at one end of the transmission tube 705 away from the electronic valve 704, the clamping calibration mechanism 7 also includes a clamping plate 707, the clamping plate 707 is fixed at one end of the piston rod 706 away from the transmission tube 705, the clamping calibration mechanism 7 also includes a laser distance sensor 708, the surface of the clamping plate 707 is embedded with the laser distance sensor 708, and the end of the laser distance sensor 708 is flush with the surface of the clamping plate 707, and a total of four laser distance sensors 708 are arranged, and the laser distance sensors 708 and the clamping plates 707 are distributed one to one, and the two laser distance sensors 708 arranged relatively are staggered with one high and one low;
[0030] The specific operation is as follows. The electric telescopic rod 409 is in a contracted state, making the center plate 408, the inner ring plate 405, and the outer ring plate 402 flush with the surface of the tooling table 1. In this state, the optical lens 5 to be detected is placed in the annular limit groove on the surface of the tooling table 1. At this time, the movable balls 6 distributed on the surfaces of the inner ring plate 405 and the outer ring plate 402 support the optical lens 5. The movable balls 6 are evenly distributed and leave a certain distance in the moving trajectory of the clamping plate 707 to facilitate the movement of the clamping plate 707 through. Based on this, the electric piston push rod 702 extends to press the hydraulic medium inside the hydraulic pipe 701, so that the hydraulic medium flows along the shunt pipe 703 into the internal of each transmission pipe 705 to push the piston rod 706 inside the transmission pipe 705 to carry the clamping plate 707 to extend and move, and each clamping plate 707 extends synchronously to push the optical lens 5 to move so that its position can be adjusted and corrected. When the optical lens 5 moves, the sliding friction force is converted into rolling friction force through the movable balls 6 to reduce the friction force to prevent the surface of the optical lens 5 from being worn. The clamping plate 707 clamps the optical lens 5 from all angles. Among them, when the clamping plate 707 extends, two relatively distributed laser distance sensors 708 are arranged in a staggered manner with one high and one low. The laser distance sensors 708 continuously monitor the distance between the two clamping plates 707. When the distance dimension is reduced to the pre-input diameter dimension of the optical lens 5, the solenoid valve 704 closes the transmission pipe 705 corresponding to these two laser distance sensors 708. Thus, when the distance dimensions monitored by the two groups of relatively distributed laser distance sensors 708 are consistent with the diameter dimension of the optical lens 5, it means that the position adjustment and calibration of the optical lens 5 are completed and the clamping is also completed at the same time. And because the extension distance of the clamping plate 707 is precisely controlled, the optical lens 5 can be prevented from being deformed due to excessive force.
[0031] In summary, when using this optical detection tooling, first place the optical lens 5 to be detected in the annular limiting groove on the surface of the tooling table 1. At this time, the electric telescopic rod 409 is in a contracted state, so that the central plate 408, the inner ring plate 405, the outer ring plate 402 are flush with the surface of the tooling table 1. Then use the clamping and calibration mechanism 7 to adjust and correct the position of the optical lens 5. Specifically, the movable balls 6 distributed on the surfaces of the inner ring plate 405 and the outer ring plate 402 carry and support the optical lens 5. The movable balls 6 are evenly distributed and leave a certain distance above the moving track of the clamping plate 707, so that the clamping plate 707 can move through. Based on this, the electric piston push rod 702 extends to push the hydraulic medium in the hydraulic pipe 701, so that the hydraulic medium flows into each transmission pipe 705 along the shunt pipe 703 to push the piston rod 706 in the transmission pipe 705 to carry the clamping plate 707 to extend and move, and each clamping plate 707 extends synchronously to push the optical lens 5 to move so that its position can be adjusted and corrected. When the optical lens 5 moves, the sliding friction force is converted into rolling friction force through the movable balls 6 to reduce the friction force to prevent the surface of the optical lens 5 from being worn. The clamping plate 707 clamps the optical lens 5 from all angles. Among them, when the clamping plate 707 extends, two relatively distributed laser distance sensors 708 are distributed in a staggered manner with one high and one low. The laser distance sensors 708 monitor the distance between the two clamping plates 707 in real time. When the distance dimension is reduced to the pre-input diameter dimension of the optical lens 5, the solenoid valve 704 closes the transmission pipe 705 corresponding to these two laser distance sensors 708. Thus, when the distance dimensions monitored by the two groups of relatively distributed laser distance sensors 708 are consistent with the diameter dimension of the optical lens 5, it means that the position adjustment and calibration of the optical lens 5 are completed and the clamping is also completed at the same time;
[0032] When it is necessary to remove the optical lens 5 after the detection is completed, first, the clamping and calibration mechanism 7 releases the clamping of the optical lens 5, and then the electric telescopic rod 409 extends stably to push the center plate 408 upward. At this time, the third movable ring 407 rises along the inside of the third limiting groove 406 with the center plate 408. When the third movable ring 407 rises to the top of the third limiting groove 406, it will drive the inner ring plate 405 upward. At this time, the second movable ring 404 rises along the inside of the second limiting groove 403 with the inner ring plate 405. When the second movable ring 404 rises to the top of the second limiting groove 403, it will drive the outer ring plate 402 upward. At this time, the first movable ring 401 rises along the inside of the first limiting groove 3 with the outer ring plate 402 until the first movable ring 401 reaches the top of the first limiting groove 3. At the same time, the electric telescopic rod 409 stops extending. At this time, the center plate 408, the inner ring plate 405, the outer ring plate 402 and the surface of the tooling table 1 form a pagoda-like structure, so that the center plate 408, the inner ring plate 405, the outer ring plate 402 and the tooling table 1 are distributed in a stepped manner from top to bottom. At this time, the center plate 408 bears the central part of the bottom of the optical lens 5, so that the optical lens 5 is stably lifted to leave the annular limiting groove, and at this time, the side of the optical lens 5 is completely exposed, so as to facilitate the U-shaped support plate to support and transfer the optical lens 5, or the clamping mechanism to clamp and transfer the optical lens 5.
