[0011] Furthermore, the rotating rod is connected to a third gear via a key on the outside of the rod body in the casing, and the driving mechanism includes a motor, which is fixedly connected to one side of the top end of the base, and a second through hole is provided at the bottom end of the casing close to the motor, and the output shaft of the motor extends to the interior of the casing at the second through hole, and one end of the output shaft of the motor is connected to a first gear via a key, the first gear is an incomplete gear, and the diameter of the first gear is smaller than the diameter of the third gear.

[0012] Furthermore, the inner walls on both sides of the base are rotatably connected to connecting rods, and the outside of the connecting rods close to the motor is connected to the second gear through a key. The diameter of the second gear is smaller than the diameter of the first gear. The second gear and the third gear are both full gears, and the second gear and the third gear are both meshed with the first gear.

[0013] Furthermore, a reciprocating screw is fixedly connected between the two connecting rods, the external thread of the reciprocating screw is connected to a nut, the top of the nut is fixedly connected to a support rod, a third through hole is opened at the bottom end of the casing on the side close to the conveyor belt, one end of the support rod extends to the outside of the casing at the third through hole, and the push plate is fixedly connected to one end of the support rod outside the casing.

At the same time, the reciprocating motion of the push plate can push out the lens that has completed the test, so as to place the lens to be tested on the fixing clamp, thereby ensuring the continuity of the test process; during the operation of this device, the operator only needs to install the lens on the fixing clamp at the same position, and the lens detection and the pushing process after the detection can be automatically carried out, so the detection is more convenient;

[0019] 2. By setting a number of fixed clips for mounting lenses at equal distances on the outside of the conveyor belt, and opening the same number of slots as the fixed clips on the outside of the turntable, the card blocks can be used to engage the turntable at the slots to achieve the stability of the position of the fixed clips after the conveyor belt moves, thereby ensuring the stability of the detection process;

[0020] 3. By setting a guide plate with an adjustable angle at the front end of the push plate, the guide plate can be used to receive the lens after the push plate pushes the lens off the fixing clamp, and smoothly guide it into a storage container or a conveyor belt, thereby avoiding the accumulation of lenses that have completed the inspection at the front end of the push plate, thereby further ensuring the smoothness of the lens inspection process.

The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0031] Example 1

[0032] Refer to the attached Figure 1-5 The present application provides a lens optical detection device, comprising a base 1, a lens transmittance measuring instrument 2 and a housing 3, wherein the housing 3 is provided with a conveying mechanism for conveying lenses, the lens transmittance measuring instrument 2 is used to detect lenses, the model of the lens transmittance measuring instrument 2 is YT1020, and the base 1 is provided with a pushing mechanism for removing lenses and a driving mechanism for driving the conveying mechanism and the pushing mechanism;

[0033] The conveying mechanism includes a transmission component and a plurality of fixed components uniformly arranged on the outside thereof. Through the uniform and intermittent movement of the transmission component, each fixed component can be moved an equal distance each time, so as to facilitate the control of the alignment adjustment of the lens and the lens transmittance measuring instrument 2. The transmission component includes a conveyor belt 9, and the fixed component includes a fixed clamp 8. The fixed clamp 8 is used to install the lens. The fixed clamp 8 realizes the installation of the lens by clamping, so it can ensure that the lens can be disassembled and assembled more conveniently. The conveyor belt 9 transmits the lens to the lens transmittance measuring instrument 2 through the fixed clamp 8. The position of the lens transmittance measuring instrument 2 is fixed. The alignment of the lens and the lens transmittance measuring instrument 2 is controlled by adjusting the fixed clamp 8. The push plate 12 is used to take out the lens from the fixing clamp 8. The driving mechanism is used to drive the conveyor belt 9 and the push plate 12 to move intermittently. The intermittent movement of the conveyor belt 9 can not only adjust the lens and the lens transmittance measuring instrument 2 to be precisely aligned, but also the movement interval of the conveyor belt 9 can also reserve detection time for the lens transmittance measuring instrument 2, so the validity of the detection result can be guaranteed. The intermittent movement of the push plate 12 can ensure that the push plate 12 can achieve the effect of pushing the lens away from the fixing clamp 8 without affecting the movement of the fixing clamp 8 with the conveyor belt 9.

[0034] Preferably, a rotating rod 11 is rotatably connected to the top of the inner wall of one side of the casing 3, and a first through hole is opened at the top of the other side of the casing 3, the rotating rod 11 extends to the outside of the casing 3 at the first through hole, and one end of the rotating rod 11 outside the casing 3 is connected to the driving wheel 10 through a key, and a support plate 4 is fixedly connected to one side of the top of the casing 3, and a connecting shaft 6 is rotatably connected to the top of one side of the support plate 4, and one end of the connecting shaft 6 is connected to the driven wheel 5 through a key, and a conveyor belt 9 is sleeved on the outside of the driving wheel 10 and the driven wheel 5, and the driving wheel 10 and the driven wheel 5 are both pulleys, and the diameters of the two are equal, and the conveyor belt 9 is a belt, which is sleeved on the outside of the above two and is in a stretched state.

[0035] Preferably, the outside of the conveyor belt 9 is equidistantly fixedly connected with a plurality of fixing piles 7, the number of the fixing clips 8 and the fixing piles 7 is the same and corresponds one to one, and the fixing clips 8 are connected to the conveyor belt 9 through the fixing piles 7, so that the fixing clips 8 can be prevented from loosening when the conveyor belt 9 alternates between the curved surface and the flat surface, thereby ensuring the stability of the lens installation, and the fixing clip 8 is fixedly connected to one end of the fixing pile 7, and the fixing clip 8 includes a torsion spring 801, a clip 802 and a gasket 803, and the number of the clips 802 is two, and the two clips 802 are respectively rotatably connected to the two ends of the fixing pile 7 The clip 802 and the fixing pile 7 are arranged on the side, and a torsion spring 801 is fixedly connected between the clip 802 and the fixing pile 7. The elastic force of the torsion spring 801 can keep the two in a state of being close to each other at all times. Therefore, when a lens is placed between the two, the clip can be used to clamp the lens. The clip 802 is arc-shaped, and the gasket 803 is arranged at the end of the fixing pile 7 and the inner side of the two clips 802. The material of the gasket 803 is rubber, and its soft nature can provide a buffering effect for the lens, and at the same time it can also increase the friction between the lens and the clip 802, thereby ensuring the stability of the lens after installation.

[0036] Preferably, the rotating rod 11 is located in the casing 3 and is connected to the third gear 15 via a key on the outside of the rod body. The driving mechanism includes a motor 18, which is fixedly connected to one side of the top end of the base 1. A second through hole is provided at the bottom end of the casing 3 near the motor 18. The output shaft of the motor 18 extends to the inside of the casing 3 at the second through hole, and one end of the output shaft of the motor 18 is connected to the first gear 17 via a key. The first gear 17 is an incomplete gear, and the diameter of the first gear 17 is smaller than the diameter of the third gear 15. When the first gear 17 rotates to have its gear teeth facing upward, it can mesh with the third gear 15 and drive it to rotate. Since the diameter of the first gear 17 is smaller than the diameter of the third gear 15, the rotation of the former will only cause the latter to deflect slowly, and deflect at an angle smaller than the sector where the gear teeth are located, thereby realizing the rotation of the fixing clamp 8 at the lens transmittance measuring instrument 2, thereby achieving the effect of detecting the lenses one by one.

[0037] Preferably, the inner walls on both sides of the base 1 are rotatably connected with connecting rods 19, and the outer part of the connecting rod 19 close to the motor 18 is connected with a second gear 20 through a key, and the diameter of the second gear 20 is smaller than the diameter of the first gear 17. The second gear 20 and the third gear 15 are all full gears, and the second gear 20 and the third gear 15 are meshed with the first gear 17. When the first gear 17 rotates to its gear teeth facing downward, it can mesh with the second gear 20 and drive it to rotate. Since the diameter of the second gear 20 is smaller than the diameter of the first gear 17, the latter can rotate. The former is driven to accelerate its rotation and rotate at an angle greater than the sector where the gear teeth are located, so as to achieve the effect of the reciprocating screw 22 driving the nut 21 to and fro, thereby providing the push plate 12 with a movement mode of pushing the lens forward and retreating to its original state. Since the first gear 17 can only mesh with one of the second gear 20 or the third gear 15 during the rotation, the push plate 12 will definitely not move when the conveyor belt 9 is running. Similarly, when the push plate 12 is telescopically moved, the conveyor belt 9 will not move, thereby ensuring the stability of the detection process.

[0038] Preferably, a reciprocating screw 22 is fixedly connected between the two connecting rods 19, and the diameter of the reciprocating screw 22 is slightly smaller than the diameter of the connecting rod 19. Therefore, when the nut 21 moves outside the reciprocating screw 22, the nut 21 will not exceed the length range of the reciprocating screw 22 and move to the outside of the connecting rod 19. The external thread of the reciprocating screw 22 is connected to the nut 21, and the top of the nut 21 is fixedly connected to the support rod 23. A third through hole is opened at the bottom end of the side of the casing 3 close to the conveyor belt 9, and one end of the support rod 23 extends to the outside of the casing 3 at the third through hole, and the push plate 12 is fixedly connected to one end of the support rod 23 outside the casing 3.

[0039] Preferably, a through groove 101 is opened at the top of the base 1 on the inner side of the casing 3, and the through groove 101 is T-shaped, and the through groove 101 includes a transverse groove and a longitudinal groove. The support rod 23 is slidably connected to the base 1 at the longitudinal groove. The longitudinal groove of the through groove 101 can limit the rotation of the support rod 23 so that it can only move along the longitudinal groove. Therefore, the stability of the nut 21 when it moves with the rotation of the reciprocating screw 22 can be ensured. The bottom end of the first gear 17 extends to the inside of the base 1 at the transverse groove, and the lens transmittance measuring instrument 2 and the casing 3 are respectively fixedly connected to the two sides of the top of the base 1.

[0040] Preferably, the rotating rod 11 is located outside the rod body in the housing 3 and is also connected to a turntable 16 through a key. A plurality of slots 1601 are equidistantly provided on the outside of the turntable 16. The slots 1601 are hemispherical, and the number of the slots 1601 is the same as the number of the fixed clips 8. Since the fixed clips 8 are evenly arranged outside the conveyor belt 9, and the slots 1601 are evenly provided outside the turntable 16, and the number of the fixed clips 8 is the same as the number of the slots 1601, each fixed clip 8 can have a slot 1601 corresponding to it. In this case, the card block 14, under the elastic force of the spring sheet 13, can clamp the turntable 16 through the slots 1601. The cooperation can realize the fixation of the position of the fixing clip 8, so as to ensure the stability of the lens on the fixing clip 8 when it is moved, adjusted and tested. The top of the housing 3 is fixedly connected with a spring sheet 13, and the bottom of the end of the spring sheet 13 is fixedly connected with a clamping block 14. The clamping block 14 is spherical, and the clamping block 14 is adapted to the clamping slot 1601. Since the outer surface of the clamping block 14 and the inner surface of the clamping slot 1601 are both arc surfaces, it can be ensured that the clamping block 14 can engage with the turntable 16. When the turntable 16 is driven to rotate, the clamping block 14 will be detached from the clamping slot 1601 due to the elastic deformation of the above-mentioned arc surface and the spring sheet 13.

[0041] Working principle: When testing the lens, the motor 18 can be started to rotate the first gear 17. When the gear teeth outside the first gear 17 rotate upward, the first gear 17 can mesh with the third gear 15 and drive it to rotate. The third gear 15 drives the turntable 16 and the driving wheel 10 to rotate through the rotating rod 11. The driving wheel 10 cooperates with the driven wheel 5 to make the conveyor belt 9 run, and the conveyor belt 9 can move the fixing clamp 8 through the fixing pile 7.

[0042] When the gear teeth outside the first gear 17 rotate downward, the third gear 15 is no longer meshed with the first gear 17, so the third gear 15 will no longer rotate. At the same time, since the first gear 17 is meshed with the second gear 20, the first gear 17 will drive the connecting rod 19 to rotate through the second gear 20. The connecting rod 19 drives the reciprocating screw 22 to rotate to allow the nut 21 to move in the horizontal direction, and the nut 21 can push the push plate 12 to move through the support rod 23;

[0043] Based on the above operation mode, the lens can be mounted on the fixing clamp 8 when the conveyor belt 9 stops, and the lens can be moved to the probe on the lens transmittance measuring instrument 2 by using the intermittent movement of the conveyor belt 9. Then, the continued rotation of the first gear 17 can make the conveyor belt 9 stop again on the one hand to leave time for the lens transmittance measuring instrument 2 to test, and on the other hand, it can also drive the push plate 12 to extend forward, so as to push the last lens that has completed the test off the fixing clamp 8, and then retract to avoid blocking the movement of the conveyor belt 9;

[0044] When the fixing clamp 8 moves to move the lens to the lens transmittance measuring instrument 2, since the driving wheel 10 and the turntable 16 are both on the rotating rod 11, the engagement of the block 14 with the turntable 16 under the elastic force of the spring sheet 13 can limit the driving wheel 10, thereby ensuring the stability of the conveyor belt 9 when it stops, and further ensuring the accurate alignment of the lens and the probe on the lens transmittance measuring instrument 2. Since the card slots are evenly opened on the outside of the turntable 16, the fixing clamps 8 are evenly arranged on the conveyor belt 9, and the number of the card slots and the fixing clamps 8 is the same, the card block 14 can achieve the position fixation of each fixing clamp 8 after moving by engaging the turntable 16 with the card slots, thereby ensuring the stability of the detection process.

[0045] Example 2

[0046] Refer to the attached Figure 6 The present application provides a detection device for lens optics. Compared with Example 1, in order to further ensure the smoothness of the lens detection process, the base 1 is fixedly connected with support rods 24 at both ends of the side close to the conveyor belt 9. One end of the two support rods 24 is rotatably connected to the same guide plate 25 through a damping shaft. The guide plate 25 can receive the lens that falls due to the push of the push plate 12, so that it can be smoothly introduced into a storage container or onto the conveyor belt, and the angle of the guide plate 25 can be adjusted by the damping shaft, so it can be suitable for different conduction degrees. A latex pad is provided at the top of the guide plate 25, which can cushion the falling lens to ensure the safety of the falling lens.

[0047] Working principle: After the push plate 12 pushes the inspected lens off the fixing clamp 8, the lens will fall onto the guide plate 25 and continue to move downward along the inclined surface of the guide plate 25. Therefore, it is only necessary to set a storage container or a conveyor belt at the lower end of the guide plate 25 to collect the inspected lenses and avoid their accumulation at the push plate 12, thereby further ensuring the smoothness of the lens inspection process.

[0048] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. The protection scope of the present invention should be based on the protection scope of the claims.
