Technical Field
[0001] This utility model relates to the field of camera lens inspection technology, specifically an inspection device for mirrorless camera lenses. Background Technology
[0002] A mirrorless lens is an interchangeable lens assembly specifically designed for mirrorless cameras. Mirrorless cameras are a common name for mirrorless cameras. They achieve a lighter body than DSLR cameras by eliminating the mirror structure, while maintaining optical performance close to that of DSLRs. Lenses are compatible with the camera body through different mounts (such as EF-M, M.Zuiko, etc.) and can be interchanged, effectively solving the contradiction between the bulkiness of traditional DSLR systems and the insufficient performance of compact cameras.

[0004] As shown in the above technology, when testing a mirrorless camera lens, the lens is placed on the testing stage. However, for lenses of different sizes, misalignment of the light source and detector may occur during testing, resulting in inaccurate test results. Furthermore, dust and other debris may adhere to the lens surface during testing, requiring cleaning to ensure the accuracy of the test results. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-5 The lens detection device for this mirrorless camera offers two technical solutions: The first embodiment includes a support platform 1, a detector 2 and a light source 3. The detector 1 is installed on the left side of the top of the support platform 1, and the light source 3 is installed on the right side of the top of the support platform. An auxiliary detection mechanism is provided between the detector 2 and the light source 3. The auxiliary detection mechanism includes a moving component 4, a height adjustment component 5 and a clamping component 6. The moving component 4 is used to move the mirrorless lens left and right to adjust the distance between the lens and the light source 3. The moving component 4 includes two slide rails 41, one at the front and one at the back. A moving stage 42 is slidably connected to the surfaces of the two slide rails 41. The height adjustment component 5 is specifically located above the moving stage 42. The top of the support platform 1 is fixedly connected to two left and right bearing seats 43, and a first lead screw 44 is rotatably connected between the two bearing seats 43. A driven gear 45 is fixedly connected to the surface of the first lead screw 44. The bottom of the support platform 1 is fixedly connected to a second drive motor 46, and the output end of the second drive motor 46 is fixedly connected to a driving gear 47. The driving gear 47 and the driven gear 45 are connected to each other. Gear 45 meshes and drives the lens. The height adjustment component 5 is used to adjust the height of the lens so that the center position of the lens is aligned with the center position of the light source 3. The clamping component 6 is set on the height adjustment component 5. The height adjustment component 5 includes four lifting rods 51 and a detection platform 52. The four lifting rods 51 are fixedly installed at the four corners of the bottom of the detection platform 52. An upper trapezoidal block 53 is fixedly connected to the bottom of the detection platform 52. A lower trapezoidal block 54 is slidably connected to the top of the moving component 4. The inclined surfaces of the upper trapezoidal block 53 and the lower trapezoidal block 54 are opposite to each other. A cleaning component 7 is provided on one side of the detection platform 52 and is used to clean the surface of the lens.
[0018] The top of the movable component 4 is fixedly connected to two second lead screws 56 on the left and right, and a rotating seat 55 is rotatably connected between the two second lead screws 56. The lower trapezoidal block 54 is threadedly connected to the surface of the rotating seat 55.
[0019] When testing a mirrorless camera, the lens is fixed by the clamping component 6. After fixing, the center position of the lens is adjusted to align with the center position of the light source by the height adjustment component 5, so as to ensure that the light source can pass through the middle part of the lens, thereby ensuring the accuracy of the test results.
[0020] The second embodiment differs from the first embodiment in that: the cleaning component 7 includes a fixed base 71 fixed to one side of the detection table 52, a rotating rod 72 rotatably connected to the fixed base 71, a first drive motor 73 fixedly connected to the left side of the rotating rod 72, a cleaning sponge 74 fixedly connected to the output end of the first drive motor 73 extending through to the right side of the rotating rod 72, an adjusting motor 75 fixedly connected to the bottom of the detection table 52, a third lead screw 76 fixedly connected to the output end of the adjusting motor 75, a moving block 77 threadedly connected to the surface of the third lead screw 76, guide rods 78 fixedly connected to both the front and back of the moving block 77, and guide grooves 79 opened on both the front and back of the rotating rod 72, with the two guide rods 78 located inside the two guide grooves 79 respectively.
[0021] Before inspecting the lens, the surface of the lens is cleaned by the cleaning component 7 to prevent dust from adhering and affecting the inspection results. At the same time, the position of the cleaning component 7 can be adjusted to avoid affecting the normal operation of the inspection.
[0022] In use, place the lens into the clamping assembly 6 and clamp it so that the lens comes into contact with the cleaning sponge 74. Start the first drive motor 73, which drives the cleaning sponge 74 to rotate and clean the lens surface. After cleaning, start the adjustment motor 75 to rotate the third lead screw 76, which in turn moves the moving block 77. The moving block 77, through the cooperation of the guide rod 78 and the guide groove 79, causes the rotating rod 72 to rotate, so that the cleaning sponge 74 moves away from the lens and does not block the lens. Also, observe whether the center position of the lens is aligned with the center position of the light source 3. If they are not aligned, rotate the rotating seat 55 to move the lower trapezoidal block 54. When the lower trapezoidal block 54 moves backward, the lens moves downward; when the lower trapezoidal block 54 moves forward, the lens moves upward.
