Description

Technical Field

[0002] In the production, research and development, and factory testing of optical lenses, optical lens testing equipment is the core equipment to ensure the imaging quality, geometric accuracy, and optical performance of the lenses. Its testing accuracy directly determines the product qualification rate and reliability of the optical lenses. Currently, optical lenses are widely used in many fields such as mobile phones, automotive, security, industrial inspection, and medical imaging. Different application scenarios have significantly different requirements for parameters such as lens size, focal length, aperture, and mounting interface, which leads to the need to frequently change lenses of different specifications during the testing process.

[0003] However, in practical applications, existing optical lens inspection devices are cumbersome and inconvenient to install when changing lenses of different specifications. The lens clamping mechanisms of existing inspection devices are mostly fixed structures, and their clamping dimensions and methods are only suitable for a single or a few lens specifications. When the size of the lens to be inspected changes, it is necessary to disassemble the original clamping components and replace them with corresponding clamps or adjustment mechanisms. This process is complex and time-consuming, not only reducing inspection efficiency but also easily causing scratches and damage to the lens surface during disassembly and installation, affecting lens quality.

[0004] Therefore, the present invention provides an optical lens inspection device to solve the above problems. Summary of the Invention

By adding a synchronous slide, a limiting shaft, a synchronous slider, a tension spring, a limiting retaining ring, a slot, and a tooth, the two vertical drive plates are controlled to clamp the lens synchronously in a direction that brings them closer to each other. The slot and tooth prevent the vertical drive plate from applying pressure to the lens after it has clamped the lens to be tested.

By adding a horizontal positioning plate, a drive ring sleeve, a guide plate, a guide groove, a guide shaft, a driven plate, a reset spring, an adjusting slider, an adjusting spring, and a push block, the lens to be tested is controlled to be in the center position, so that the axis of the lens to be tested and the detection light source are coaxial. By adding a drop limit bracket, a limit slide, a drop limit groove, a drop limit roller, a guide push rod, a connecting plate, a self-locking spring, an unlocking control shaft, an arc-shaped unlocking push plate, and a triangular guide block, the stability of the lens clamping is improved and the lens under test is prevented from moving downward under the action of gravity.

[0025] Furthermore, specific details are provided in the following description to facilitate a thorough understanding of the examples. However, those skilled in the art will understand that the described aspects can be practiced without these specific details.

[0026] Example 1, refer to the appendix of the instruction manual. Figure 1-15 An optical lens inspection device includes a base 1, a fixed frame 2 slidably connected to the base 1, a detection light source 3 fixedly installed on the base 1, a lens inspection imager 4 provided at the end of the base 1 away from the detection light source 3, a threaded shaft 52 rotatably connected to the base 1, and the fixed frame 2 and the threaded shaft 52 being threadedly connected. In use, the fixed frame 2 is moved by rotating the threaded shaft 52. The fixed frame 2 is set as a ring and is provided with a clamping structure for clamping the inspection lens. The clamping structure includes two vertical clamping plates 5 that are slidably connected to the upper and lower sides of the fixed frame 2, respectively. The vertical clamping plates 5 are slidably connected to the fixed frame 2. In use, the vertical clamping plates 5 can only slide up and down. An arc-shaped rubber pad is fixedly connected to one side of the vertical clamping plate 5 near the middle of the fixed frame 2 to facilitate the fit of the lens to be tested. The two vertical clamping plates 5 are slidably connected to the fixed frame 2. Two arc-shaped drive plates 6 are rotatably connected inside the fixed frame 2 to push the vertical clamping plates 5 to slide. A vertical drive plate 7 is provided at one end of the arc-shaped drive plate 6 near the vertical clamping plate 5. The vertical drive plate 7 has an inclined vertical push groove 8. Vertical drive shafts 9 are provided on both sides of the vertical clamping plate 5 and are slidably connected to the vertical push groove 8.

[0027] The fixed frame 2 is equipped with a synchronous drive structure for controlling the arc-shaped drive plate 6 to slide synchronously inside the fixed frame 2; The synchronous drive structure includes a drive gear 10 rotatably connected inside the fixed frame 2. Both ends of the drive gear 10 are provided with synchronous gears 11. The ends of the two arc-shaped drive plates 6 away from the vertical drive plate 7 are provided with multiple meshing teeth 12. The synchronous gear 11 meshes with the meshing teeth 12 on one of the arc-shaped drive plates 6. The fixed frame 2 is rotatably connected with a driven gear 13 that meshes with the synchronous gear 11. The driven gear 13 meshes with the meshing teeth 12 on the other arc-shaped drive plate 6. One end of an arc-shaped control plate 14 is rotatably connected to one side of the fixed frame 2. A support torsion spring is provided between the arc-shaped control plate 14 and the fixed frame 2. In the initial state, under the action of the support torsion spring, the arc-shaped control plate 14 is pushed away from the fixed frame 2. A drive tongue plate 15 is fixedly connected to the side of the arc-shaped control plate 14 near the inside of the fixed frame 2. The drive tongue plate 15 is arc-shaped and has meshing teeth 16 that mesh with multiple drive gears 10.

[0028] The drive gear 10 is hollow inside. The synchronizing gear 11 is rotatably connected to both ends of the drive gear 10. The synchronizing gear 11 has a synchronizing groove 17 inside. The synchronizing gear 11 is slidably connected to a limiting shaft 18. A synchronizing slider 19 that cooperates with the synchronizing groove 17 is fixedly connected to the limiting shaft 18. A tension spring 20 is provided between the drive gear 10 and the limiting shaft 18. Both ends of the drive gear 10 are fixedly connected to limiting rings 21. The end of the limiting ring 21 near the synchronizing gear 11 has multiple triangular slots 22. The end of the limiting shaft 18 near the limiting ring 21 has multiple teeth 23 that cooperate with the slots 22. The teeth 23 are also triangular.

[0029] In the initial state, the tension spring 20 pulls the limiting shaft 18 to move closer to the inside of the drive gear 10. The limiting shaft 18 is located inside the synchronous gear 11, so that the locking tooth 23 is locked into the slot 22. At this time, the drive gear 10 rotates and synchronously drives the synchronous gear 11 to rotate.

[0030] In use, the lens to be tested is placed inside the fixture 2, and then the arc-shaped control plate 14 is rotated. The mating teeth 16 on the drive tongue plate 15 mesh with the drive gear 10, which in turn drives the drive gear 10 to rotate. The drive gear 10 drives the synchronous gears 11 at both ends to rotate through the synchronous slider 19 and the synchronous slide groove 17. The synchronous gears 11 synchronously drive the driven gear 13 to rotate. When the synchronous gears 11 and the driven gears 13 rotate synchronously, the meshing teeth 12 simultaneously drive the two arc-shaped drive plates 6 to rotate inside the fixture 2. This drives the vertical drive shaft 9 to move towards the middle position of the fixture 2 through the vertical push groove 8 on the vertical drive plate 7. The vertical drive shaft 9 drives the vertical pressing plate 5 to press the lens to be tested towards the middle position of the fixture 2. After the vertical clamping plate 5 clamps the lens to be tested, the arc-shaped control plate 14 continues to rotate. At this time, the vertical clamping plate 5 can no longer move closer to the inside of the fixed frame 2. The drive gear 10 continues to rotate, driving the limit ring 21 to rotate. The synchronous gear 11 can no longer rotate. Therefore, through the inclined guide of the slot 22 and the tooth 23, the limit shaft 18 is pushed away from the inside of the drive gear 10. This setting is convenient for protecting the lens to be tested, and can clamp lenses of different sizes while preventing them from being crushed.

[0031] In embodiment 2, horizontal positioning plates 24 are slidably connected to both the left and right sides of the fixed frame 2. The horizontal positioning plates 24 can slide horizontally and move towards or away from the center position of the fixed frame 2. A drive ring sleeve 25 is rotatably connected inside the fixed frame 2. A guide plate 26 for driving the horizontal positioning plates 24 to slide is provided on the drive ring sleeve 25. An inclined guide groove 27 is provided on the guide plate 26. A guide shaft 28 that cooperates with the guide groove 27 is provided on the horizontal positioning plate 24. A driven ring sleeve 25 is provided with a driven plate 29. A return spring 30 is provided between the driven plate 29 and the fixed frame 2. In the initial state, under the action of the return spring 30, the driven ring sleeve 25 is pushed to the initial position. At this time, the horizontal positioning plate 24 is located at the extreme position far away from the center of the fixed frame 2. An adjusting slider 31 is slidably connected to the driven plate 29. An adjusting spring 32 is provided between the adjusting slider 31 and the driven plate 29. The elastic force of the adjusting spring 32 is greater than the elastic force of the return spring 30. In the initial state, the adjusting spring 32 pushes the adjusting slider 31 to the farthest position away from the driven plate 29. The drive tongue plate 15 is provided with a push block 33 that cooperates with the adjusting slider 31. The cross section of the push block 33 is set as a triangle.

[0032] In use, the lens to be tested is placed inside the mounting bracket 2. The arc-shaped control plate 14 is rotated, and the inclined surface of the push block 33 first contacts the adjusting slider 31. Then, the inclined surface of the push block 33 pushes the adjusting slider 31 to move. The elastic force of the adjusting spring 32 is greater than that of the return spring 30. Therefore, the push block 33 first pushes the adjusting slider 31 and the driven plate 29 to compress the return spring 30. The adjusting slider 31 and the driven plate 29 push the drive ring sleeve 25 to rotate. When the drive ring sleeve 25 rotates, it drives the guide plate 26 to rotate. The guide groove 27 drives the guide shaft 28 to move towards the middle position of the mounting bracket 2, thereby clamping the lens in the horizontal direction. This setting facilitates lens fixation and also facilitates control of the lens and light source to be coaxial. After the horizontal positioning plate 24 contacts the lens, continue to push the rotating arc control plate 14. Through the push block 33, continue to push the adjusting slider 31 towards the driven plate 29 to compress the adjusting spring 32, so that the adjusting slider 31 moves towards the driven plate 29, which is convenient to protect the lens to be tested and can press the lens to be tested of different sizes while preventing it from being crushed.

[0033] The drive tongue plate 15 is provided with a plurality of spaced-apart pressing rubber strips 34 at one end near the drive ring sleeve 25. The pressing rubber strips 34 are used to abut against the outer wall of the drive ring sleeve 25 and press the drive ring sleeve 25.

[0034] When the arc-shaped control plate 14 rotates to fit with the fixed frame 2, it presses the rubber strip 34 and the drive ring sleeve 25 to fit together, thereby fixing the drive ring sleeve 25 in the current position.

[0035] In Example 3, based on Example 2, a horizontally sliding plate 35 is horizontally connected to the side of the two vertical pressing plates 5 that are close to each other. A positioning spring 36 is provided between the horizontally sliding plate 35 and the vertical pressing plate 5. The side of the horizontally sliding plate 35 that is close to each other is set as an arc surface.

[0036] In the initial state, the horizontal moving plate 35 is pulled to the center position of the vertical pressing plate 5 under the action of the positioning spring 36. After the horizontal positioning plate 24 contacts the lens, the rotating arc control plate 14 is pushed to adjust the position of the lens to be tested and further control the position of the lens so that the lens and the light source are coaxial.

[0037] In embodiment four, a drop limiting frame 37 is fixedly connected to the lower end of the fixed frame 2. A limiting groove 38 is opened inside the drop limiting frame 37. A vertical pressing plate 5 located at the lower end of the fixed frame 2 is slidably connected to the limiting groove 38. A drop limiting groove 39 is opened at the upper end of the limiting groove 38. A drop limiting roller 40 is movably installed inside the drop limiting groove 39. Two guide push rods 41 are provided inside the drop limiting frame 37 on both sides of the limiting groove 38. The upper end of the guide push rod 41 is provided with an inclined surface that cooperates with the drop limiting roller 40. A connecting plate 42 is fixedly connected to the lower end of the guide push rod 41. A self-locking spring 43 is provided between the connecting plate 42 and the drop limiting frame 37. An unlocking control shaft 44 is provided on the connecting plate 42. An arc-shaped unlocking push plate 45 is slidably connected to the outside of the fixed frame 2. A triangular guide block 46 that cooperates with the unlocking control shaft 44 is fixedly connected to one end of the arc-shaped unlocking push plate 45.

[0038] In the initial state, the connecting plate 42 and the guide push rod 41 are pushed upward by the self-locking spring 43. Under the action of the inclined surface of the guide push rod 41, the drop limit roller 40 is pushed towards the vertical pressing plate 5. In use, when the vertical pressing plate 5 moves upward, it drives the drop limit roller 40 to move upward. At this time, it does not affect the upward movement of the vertical pressing plate 5. When the vertical pressing plate 5 moves downward under the action of gravity, it pushes the drop limit roller 40 downward. Under the action of the inclined surface of the guide push rod 41, it pushes the drop limit roller 40 towards the vertical pressing plate 5, thereby pressing the vertical pressing plate 5. The vertical pressing plate 5 cannot move downward. When the vertical pressing plate 5 needs to move downward, push the arc-shaped unlocking push plate 45, and push the unlocking control shaft 44 downward through the triangular guide block 46 to compress the self-locking spring 43. At this time, the guide push rod 41 moves downward. The inclined surface of the guide push rod 41 cannot guide the falling limit roller 40. When the vertical pressing plate 5 slides downward, the falling limit roller 40 moves away from the vertical pressing plate 5, which does not affect the downward movement of the vertical pressing plate 5.

[0039] In Example 5, the end of the arc-shaped unlocking push plate 45 away from the triangular guide block 46 is fixedly connected to a limiting block 47 for restricting the rotation of the arc-shaped control plate 14. The limiting block 47 is triangular. When the arc-shaped control plate 14 rotates to fit against the outer wall of the fixing frame 2, the swing end of the arc-shaped control plate 14 contacts the inclined surface of the limiting block 47. Then, the limiting block 47 and the arc-shaped unlocking push plate 45 are pushed to slide away from the arc-shaped control plate 14 until the swing end of the arc-shaped control plate 14 slides past the limiting block 47. Under the action of the self-locking spring 43, the connecting plate 42 is pushed to move upward. The limiting block 47 is pushed back to the initial position through the unlocking control shaft 44 and the triangular guide block 46, restricting the arc-shaped control plate 14 to the current position. When unlocking is required, the arc-shaped unlocking push plate 45 is pushed away from the arc-shaped control plate 14. At this time, under the action of the support torsion spring, the arc-shaped control plate 14 is pushed to swing away from the fixing frame 2.

[0040] In embodiment six, both ends of the horizontal moving plate 35 located at the lower end of the fixed frame 2 are rotatably connected to fixed claws 48. A clamping torsion spring is provided between the fixed claws 48 and the horizontal moving plate 35. The clamping torsion spring is used to push the fixed claws 48 to swing in a direction that brings them closer to each other. The side of the fixed claws 48 that is opposite to each other is fixedly connected to a mating half shaft 49 that mates with the inner sidewall of the fixed frame 2. Both sides of the horizontal moving plate 35 are fixedly connected with self-locking plates 53. A self-locking block 54 is slidably connected to one end of the self-locking plate 53 near the fixed gripper 48. A self-locking groove 55 that cooperates with the self-locking block 54 is opened at one end of the fixed gripper 48 near the horizontal moving plate 35. A compression spring 56 is provided between the self-locking plate 53 and the horizontal moving plate 35. In the initial state, the self-locking plate 53 is pushed to move towards the fixed gripper 48 under the action of the compression spring 56. A vertical limiting housing 50 is slidably connected to the lower end of the vertical pressing plate 5 below the fixed frame 2. A clamping control spring 51 is provided between the vertical limiting housing 50 and the vertical pressing plate 5. In the initial state, the vertical pressing plate 5 is pushed upward by the clamping control spring 51. The vertical limiting housing 50 is located inside the limiting slide groove 38. The vertical drive shaft 9 is installed on the vertical limiting housing.

[0041] In the initial state, under the action of the clamping control spring 51, the vertical clamping plate 5 is pushed upward a certain distance, and the self-locking block 54 is locked inside the self-locking slot 55. At this time, the fixed jaw 48 is restricted to the current position, and the two fixed jaws 48 are in the open state. When in use, the lens to be tested is placed between the two fixed jaws 48, and then the vertical clamping plate 5 is pressed down, compressing the clamping control spring 51 downward. After the half shaft 49 contacts the inner wall of the fixing frame 2, the fixed jaw 48 is rotated a certain angle by the guide of the half shaft 49, and the self-locking block 54 is pushed out from the self-locking slot 55. Under the action of the clamping torsion spring, the lens to be tested is restricted to the current position. After use, pull the two fixed claws 48 apart in a direction away from each other until the self-locking block 54 is re-locked into the self-locking slot 55.
