Description

Technical Field

[0001] This utility model belongs to the field of lens inspection, specifically an optical lens inspection device. Background Technology

[0002] Optical lens testing refers to the process of comprehensively evaluating and verifying key indicators such as optical performance, mechanical structure, and environmental adaptability of optical lenses through a series of technical means and equipment. The purpose is to ensure that the lens meets the design requirements and works stably and reliably in practical applications.

[0003] Existing optical lens inspection devices typically fix the optical lens on an inspection fixture during the inspection process. The inspection head then checks a series of parameters such as the lens's resolution and image quality. However, the lens inspection process usually requires checking not only the incident end but also the exit end. Since the position of the inspection head is fixed relative to the camera fixed in the fixture, the lens needs to be removed from the fixture, flipped, and re-clamped. The positioning accuracy of each clamping is affected by the repeatability error of the fixture, which affects the accuracy of the data and makes the operation cumbersome.

[0004] To address the problems raised in the background art, those skilled in the art have proposed an optical lens inspection device. Utility Model Content

The bidirectional screw is rotatably mounted on the inner side of the clamping frame. Two sets of connecting rods are connected to the bidirectional screw with opposing threads. One end of the two sets of connecting rods is connected to an arc plate that fits against the outer wall of the optical lens to be tested. The other end of the two sets of connecting rods is connected to a guide block. A guide groove is provided in the clamping frame for the guide block to move.

[0008] Preferably, the fixing assembly further includes a servo motor, a worm gear, and a worm wheel. Mounting plates are provided on the top and bottom of the side of the clamping frame. A worm gear is rotatably arranged between the two sets of mounting plates. A worm wheel is meshed on one side of the worm gear. The worm wheel is installed in the middle of the bidirectional screw. The servo motor is installed on the corresponding mounting plate, and the output end of the servo motor is connected to the worm gear.

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides an optical lens inspection device, including an inspection box 1, a clamping frame 2, a fixing component 3, a temporary storage component 4, and a flipping mechanism 5. The front end of the inspection box 1 is set as an open structure. A connecting column 6 is provided on the inner wall of the inspection box 1. A clamping frame 2 is provided at one end of the connecting column 6. A fixing component 3 is provided inside the clamping frame 2. A temporary storage component 4 for temporarily placing optical lenses is movably provided at the bottom of the clamping frame 2. A gear plate 7 is rotatably provided in the middle of the connecting column 6. A connecting plate 8 is provided on the top of the side of the gear plate 7. An inspection head 9 is provided at one end of the connecting plate 8. A flipping mechanism 5 is provided on one side of the gear plate 7 for driving the inspection head 9 to rotate around the connecting column 6.

[0025] refer to Figure 3 , Figure 4 and Figure 5 The fixing component 3 includes a bidirectional screw 31, a connecting rod 32, an arc plate 33, and a guide block 34. The bidirectional screw 31 is rotatably arranged inside the clamping frame 2. Two sets of connecting rods 32 are connected to the bidirectional screw 31 with opposite threads. One end of the two sets of connecting rods 32 is connected to the arc plate 33, which fits against the outer wall of the optical lens to be tested. The other end of the two sets of connecting rods 32 is connected to the guide block 34. A guide groove 21 is provided inside the clamping frame 2 for the guide block 34 to move.

[0026] The two sets of arc plates 33 move synchronously in opposite directions through the cooperation of the bidirectional screw 31 and the connecting rod 32 with opposite threads. The constraint design of the guide block 34 and the guide groove 21 ensures that the clamping movement is smooth and without deviation, so that the lens clamping center automatically coincides with the detection optical axis of the detection head 9, reducing the image quality detection error caused by clamping eccentricity.

[0027] refer to Figure 5The fixing component 3 also includes a servo motor 35, a worm gear 36, and a worm wheel 37. Mounting plates 22 are provided on the top and bottom of the side of the clamping frame 2. A worm gear 36 is rotatably arranged between the two sets of mounting plates 22. A worm wheel 37 is meshed on one side of the worm gear 36. The worm wheel 37 is installed in the middle of the bidirectional screw 31. The servo motor 35 is installed on the corresponding mounting plate 22. The output end of the servo motor 35 is connected to the worm gear 36.

[0028] Among them, the servo motor 35 drives the worm gear 36 to rotate the worm wheel 37, realizing precise step control of the bidirectional screw 31 and avoiding random errors of traditional manual adjustment; at the same time, the self-locking function prevents the clamping force from weakening during the detection process, ensuring that the lens is stably fixed in a vibrating environment such as resolution testing.

[0029] refer to Figure 3 The inner walls of the two sets of arc plates 33 on opposite sides are provided with anti-damage pads.

[0030] The impact force is buffered by a flexible material anti-damage pad.

[0031] refer to Figure 3 The temporary storage component 4 includes a movable pile 41 and a support platform 42. The movable pile 41 is movably disposed on the top of the inner side of the detection box 1, and the support platform 42 is disposed on the top of the movable pile 41.

[0032] The movable support platform 42 provides a temporary placement position for the lens, preventing the lens from being suspended in the air when it is waiting to be fixed.

[0033] refer to Figure 2 and Figure 3 The temporary storage component 4 also includes a slider 43 and a limiting shaft 44. A strip-shaped through groove 11 is provided at the bottom of the detection box 1. A limiting shaft 44 is provided in the strip-shaped through groove 11. A slider 43 is slidably provided on the limiting shaft 44. The slider 43 is connected to the moving pile 41.

[0034] The linear guide rail structure formed by the limiting shaft 44 and the slider 43 constrains the movement trajectory of the moving pile 41 to be a horizontal straight line, avoiding swaying or tilting when manually pulled, and ensuring that the lens on the support platform 42 is located between the two arc plates 33.

[0035] refer to Figure 2 The movable stake 41 is provided with a handle 411 for pulling on its side.

[0036] After clamping, the support platform 42 can be removed from the detection range by using handle 411.

[0037] refer to Figure 4The flipping mechanism 5 includes a drive motor 51 and a gear 52. The drive motor 51 is installed at the bottom of the back of the detection box 1. The output end of the drive motor 51 passes through the detection box 1 and is connected to the gear 52. The gear 52 meshes with the gear plate 7.

[0038] The drive motor 51 meshes with the gear 7 through the gear 52 to enable the detection head 9 to automatically rotate, thereby performing bidirectional detection on the incident and exit ends of the optical lens.

[0039] Working principle: By pulling the handle 411 on the side of the movable pile 41, the support platform 42 is moved horizontally along the linear guide rail formed by the limiting shaft 44 and the slider 43 to directly below the clamping position. The optical lens to be tested is placed on the support platform 42. Then, the servo motor 35 is started to drive the worm gear 36 to rotate, which drives the bidirectional screw 31 to rotate precisely in steps through the worm wheel 37. The connecting rod 32 with opposite threads on it is constrained by the guide block 34 and the guide groove 21, and synchronously pushes the two sets of arc plates 33 with anti-damage pads to clamp the lens. The head utilizes the self-locking characteristics of the worm gear 37 and worm 36 to ensure stable clamping force. During testing, the drive motor 51 drives the testing head 9 to automatically rotate around the central axis of the connecting column 6 through the meshing transmission of the gear 52 and the toothed disc 7. First, the resolution and image quality of the lens incident end are tested. After rotating 180°, the bidirectional test of the exit end is completed. The lens does not need to be disassembled or assembled throughout the process. After the test is completed, the support platform 42 is reset to the bottom of the clamping frame 2, and then the fixing component 3 is loosened. The lens is placed on the support platform 42, and the operator can then remove the tested lens.
