All positions of the lens can be detected, including the areas originally blocked by adsorption and clamping, so as to obtain complete and accurate lens thickness data, avoid the deviation of the detection result caused by the lack of data in some areas, and there is no need to perform multiple clamping of the lens or adopt multiple different detection methods to make up for the detection of the blocked area, saving the detection time and labor cost, improving the overall detection efficiency, making the detection process smoother and more efficient.

[0020] 2. Through the cooperation of the picking and placing mechanism and the adjustment mechanism, the qualified lenses can be transferred to the first discharge rack for discharging, and the unqualified lenses can be transferred to the second discharge rack for discharging. When detecting the lenses, the transfer of the lenses can be automatically completed, and at the same time, the good and bad classification transfer of the detected lenses can also be automatically carried out, which is beneficial to realizing the continuous detection of the lenses, avoiding the time-consuming and labor-consuming problem caused by the manual feeding and discharging of single lenses, and enabling the device to meet the industrial requirements of mass optical lens detection.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] To solve the technical problems of low efficiency of manual loading and unloading and inability to separate unqualified lenses, as Figures 1-4 shown, the following preferred technical solutions are provided: An optical lens thickness detection device includes a workbench 1 and an adjustment mechanism 5 arranged on one side above the picking and placing mechanism 4. A picking and placing mechanism 4 is arranged in the middle above the workbench 1. Two groups of detection heads 2 are oppositely arranged above and below the workbench 1. The upper and lower two groups of detection heads 2 are existing laser thickness measurement probes, which are respectively a light emitting source and a light receiving source. And a feeding rack 3 is arranged in the middle at the rear of the workbench 1, a first discharging rack 8 is arranged in the middle at the front of the workbench 1, and a second discharging rack 9 is arranged in the middle on one side of the workbench 1. A control box 10 is installed on one side above the workbench 1. The feeding rack 3, the first discharging rack 8 and the second discharging rack 9 are all common existing conveyor belts. An electric slide rail is arranged between the detection head 2 and the workbench 1, and it can move back and forth to perform thickness detection on the lens from the middle to the edge;

[0035] The picking and placing mechanism 4 includes a first motor 401 installed on one side below the workbench 1. A first synchronous belt 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 belt pulley 402. The rotating disk 403 is rotationally connected to the workbench 1 through the first synchronous belt pulley 402 and the first motor 401. A through hole 11 is opened in the middle of the rotating disk 403. Through the through hole 11, light can pass through to enable the detection head 2 to detect the lens;

[0036] Two mounting seats 404 are installed on both sides above the rotating disk 403. A swing arm 405 is rotationally connected to the upper side of one side of the mounting seat 404. A second motor 406 is installed on the outer side of one side of the swing arm 405, and an output end of the second motor 406 is rotationally connected to an intermittent gear 407. The convex teeth of the intermittent gear 407 are distributed at a quarter of the outer surface. A lower mating wheel 408 with full convex teeth is arranged below the intermittent gear 407. The swing arm 405 is rotationally connected to the mounting seat 404 through the second motor 406, the intermittent gear 407 and the lower mating wheel 408;

[0037] Above the clearance gear 407, there is an upper mating wheel 409 with full convex teeth. Above the rear part of the upper mating wheel 409, a second synchronous pulley 410 is rotatably connected. The upper end of the second synchronous pulley 410 is rotatably connected with a rotating frame 411. The clearance gear 407 is rotatably connected with the rotating frame 411 through the upper mating wheel 409 and the second synchronous pulley 410. An interference fit of spring steel material is adopted between the lower mating wheel 408 and the shaft of the mounting seat 404, and between the upper mating wheel 409 and the shaft of the swing arm 405, so as to ensure that the lower mating wheel 408 and the upper mating wheel 409 can keep non-rotating with the axial connection part without applying a rotational force. Through the picking and placing mechanism 4, the detected lens can be automatically moved and adjusted;

[0038] By means of the second servo motor 406, the clearance gear 407 is driven to rotate counterclockwise, which can make the clearance gear 407 drive the lower mating wheel 408 to rotate clockwise by 90 degrees, so that the swing arm 405 and the mounting seat 404 rotate clockwise by 90 degrees. After the subsequent adjustment mechanism 5 sucks the lens, the second motor 406 drives the clearance gear 407 and the lower mating wheel 408 to reverse counterclockwise by 90 degrees, so that the sucked lens is vertically lifted again by the swing arm 405. By rotating the clearance gear 407 clockwise upward, the upper mating wheel 409 can be driven under the linkage of the second synchronous pulley 410, so that the rotating frame 411 rotates counterclockwise by 90 degrees, so that the vertically lifted lens can be horizontally placed, and the placed lens is located at the center position of the detection head 2, so as to facilitate the detection head 2 to detect the thickness of the lens. By means of the first servo motor 401 and the first synchronous pulley 402, after the detection, the rotating disk 403 and the swing arm 405 thereon can be driven to rotate clockwise by 90 degrees or 180 degrees. When the lens thickness is detected to be qualified, it rotates clockwise by 180 degrees. Cooperating with the rotation of the swing arm 405 and the discharging of the adjustment mechanism 5, the qualified lens can be transferred to the first discharging rack 8 for discharging. When the thickness detection is unqualified, it rotates clockwise by 90 degrees to transfer the unqualified lens to the second discharging rack 9 for discharging. Therefore, when detecting the lens, the transfer of the lens can be automatically completed, and at the same time, the detected lens can be automatically classified and transferred as good or bad, which is beneficial to realizing the continuous detection of the lens, avoiding the time-consuming and labor-consuming problems caused by the manual feeding and discharging of single lenses, and enabling the device to meet the industrial requirements of mass optical lens detection.

[0039] ]To solve the technical problem that due to the reason of optical path occlusion, the thickness information of the occluded area cannot be accurately obtained, and it is often necessary to re-inspect to ensure the measurement accuracy, which will affect the finished product yield and the processing efficiency at the same time, such as Figures 1-10As shown in the figure, the following preferred technical solutions are provided: The adjustment mechanism 5 includes an air distribution cover 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 cover 501. A first air duct 503 is connected to the rear surface of the air distribution cover 501. A first solenoid valve 504 is provided on the front side of the first air duct 503;

[0040] A semi-circular ring frame 505 is provided on one front side of the air distribution cover 501. A piston chamber 506 is provided on the surface of the semi-circular ring frame 505. A second solenoid valve 507 is installed on one upper side of the piston chamber 506. A second air duct 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. 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. 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. A rolling wheel 514 is connected to the front end of the reduction motor 513;

[0041] The vacuum suction head 502 is communicated with the first air duct 503 and the first solenoid valve 504 through the air distribution cover 501. Four groups of piston chambers 506 are annularly distributed with respect to the semi-circular ring frame 505. The piston chamber 506 is communicated with the first air duct 503 through the second solenoid valve 507 and the second air duct 508. The piston plate 510 is slidably connected to the piston chamber 506 through the connecting frame 511. The reduction motor 513 is rotationally connected to the rolling wheel 514 through the installation head 512. The first air duct 503 and the second air duct 508 are connected to an external vacuum pump of the existing device. Through the adjustment mechanism 5, the radially rotated adjustment of the adsorbed lens can be performed, so that the lens can be comprehensively detected;

[0042] Through the air distribution cover 501 and the vacuum suction head 502, when the swing arm 405 rotates downward, it fits with the surface of the lens. By closing the second solenoid valve 507 and opening the first solenoid valve 504, the vacuum suction head 502 can be evacuated through the first air duct 503. At this time, the air distribution cover 501 and the vacuum suction head 502 can adsorb and fix the lens. After the lens is rotated and adjusted horizontally by the picking and placing mechanism 4 and covered by the covering mechanism 6, by closing the first solenoid valve 504 and opening the second solenoid valve 507, the suction force of the vacuum suction head 502 at the bottom of the horizontally placed lens disappears. Through the second air duct 508, the piston chamber 506 can be evacuated. At this time, an inward thrust will be generated at the air inlet 509 on the piston plate 510 and the connecting frame 511, so that the connecting frame 511 drives the mounting head 512 and the rolling wheel 514 to move inward, and the rolling wheels 514 in multiple piston chambers 506 distributed annularly on the two half-ring frames 505 fit onto the side surface of the lens. Through the same number of small reduction motors 513 provided, the rolling wheels 514 can be driven to rotate synchronously, so that the lens can rotate radially within the half-ring frame 505, and then the clamped part of the lens can be radially rotated outwards, realizing the automatic dynamic detection of the lens, being able to detect all positions of the lens, including the areas originally blocked by adsorption and clamping, so as to obtain complete and accurate lens thickness data, avoiding detection result deviations caused by missing data in some areas, and there is no need to perform multiple clamping of the lens or use multiple different detection methods to make up for the detection of the blocked area due to the occlusion problem, saving detection time and labor costs, improving the overall detection efficiency, and making the detection process smoother and more efficient.

[0043] In order to solve the technical problems of inconvenient clamping of special-shaped mirrors and inability to ensure the stable safety of the lens during adjustment, such as Figures 5-7 and Figure 10 as shown, the following preferred technical solutions are provided: A covering mechanism 6 is provided on one side of the adjustment mechanism 5. The covering mechanism 6 includes a rotating plate 601 connected to one side of the air distribution cover 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 rotationally connected to the air distribution cover 501 through the rotating motor 603 and the rotating shaft 602. The other end of the rotating plate 601 is fixed with a covering arc plate 604, and an elastic column 605 is installed on the inner surface of the covering arc plate 604. A first ball 606 is provided on the front surface of the elastic column 605. The elastic column 605 is elastically connected to the covering arc plate 604 by a spring at the inner bottom.

[0044] A support mechanism 7 is provided in the middle of the adjustment mechanism 5. The support mechanism 7 includes a folding tube 701 disposed behind the vacuum suction head 502. A support cover 702 is provided at the front end of the folding tube 701. A second ball 703 is provided on the front surface of the support cover 702. Both the first ball 606 and the second ball 703 are provided with smooth rubber outer layers, which can prevent wear and at the same time facilitate the radial rotation of the lens after closing. Through the closing mechanism 6 and the support mechanism 7, the clamping of the special-shaped lens can be realized, and at the same time, the lens can be kept stable when adjusting the lens to prevent the lens from falling off.

[0045] 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 distribution cover 501 adsorbs the lens and rotates and adjusts horizontally, the covering arc plate 604 can be used to 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 surface when adsorbing and rotating and covering and fitting the lens surface, so as to complete the clamping of the special-shaped lens and avoid the problem that the lens is inclined due to inconsistent fitting, which affects the detection accuracy. At the same time, when the adsorption force of the vacuum suction head 502 on the lens disappears and when the lens rotates radially, the upper and lower air distribution cover 501 and the covering arc plate 604 can also support and limit the lens to ensure the stability and safety during radial rotation and prevent the lens from falling off and being damaged.
