[0036] As Figures 1-5 shown, an embodiment of the present utility model provides a lens light detection device, which includes a connection base 1 and a rotating member 2. Among them, the connection base 1 is fixedly connected to the camera module board 200 of the camera, and the connection base 1 is provided with a first threaded hole 121; an outer thread matching the first threaded hole 121 is provided on the outer peripheral wall of the rotating member 2, and the rotating member 2 is threadedly connected to the first threaded hole 121 through the outer thread and the first threaded hole 121, and an installation hole 21 is provided on the end face of the rotating member 2 away from the connection base 1. The lens to be tested 100 can be installed in the installation hole 21, and a through hole 211 for communicating the lens to be tested 100 and the camera module board 200 is provided at the bottom of the installation hole 21. By providing the through hole 211, the camera can image through the lens to be tested 100. Rotating the rotating member 2 can make the rotating member 2 approach or move away from the camera module board 200 along the axis direction of the first threaded hole 121, so as to adjust the distance between the lens to be tested 100 and the camera module board 200, that is, adjust the focal length of the lens to be tested 100, realize adjusting the lens to be tested 100 to the focusing position, and complete light imaging through the camera.

[0037] The lens light detection device fixes the connecting seat 1 to the camera module board 200. The rotating member 2 is threadedly connected to the connecting seat 1, and the rotating member 2 is provided with a mounting hole 21 for mounting the lens to be tested 100. The lens to be tested 100 is mounted in the mounting hole 21, realizing the mounting of the lens to be tested 100. Then, rotating the rotating member 2 can adjust the distance between the lens to be tested 100 and the camera module board 200, and the lens to be tested 100 is adjusted to the focusing position. Through this lens light detection device, the quick installation and focal length adjustment of the lens to be tested 100 are realized, improving the light detection efficiency of the lens to be tested 100.

[0038] Optionally, the mounting hole 21 is a light hole, and the lens to be tested 100 can be directly placed in the mounting hole 21 to realize the mounting of the lens to be tested 100, and there is a clearance fit between the lens to be tested 100 and the mounting hole 21. This structure makes the installation of the lens to be tested 100 more convenient, can effectively save the installation time of the lens to be tested 100, and improve the light detection efficiency of the lens to be tested 100.

[0039] Optionally, the lens light detection device further includes a vacuum device, which is used to generate a vacuum in the mounting hole 21 to adsorb the lens to be tested 100 in the mounting hole 21. By setting the vacuum device to generate a vacuum in the mounting hole 21, the vacuum suction force can make the lens to be tested 100 more firmly mounted in the mounting hole 21 without the risk of falling.

[0040] It should be noted that when performing light detection through this lens light detection device, the lens to be tested 100 faces upward or is inclined upward. Therefore, even if the vacuum device is not set, during normal use, the lens to be tested 100 will not fall out of the mounting hole 21.

[0041] Furthermore, as Figure 2 and Figure 4 shown, the connecting seat 1 includes a mounting portion 11 and a first connecting portion 12. The first connecting portion 12 is provided with a first threaded hole 121. The mounting portion 11 is disposed on the camera module board 200, and a notch 111 communicating with the first threaded hole 121 is provided on the end surface of the mounting portion 11 connected to the camera module board 200. An air hole communicating with the notch 111 is provided on the side wall of the mounting portion 11. The vacuum device is communicated with the air hole through a trachea 112. In this structure, the vacuum device can generate a vacuum in the notch 111 through communication with the air hole. The notch 111 is communicated with the first threaded hole 121, and the rotating member 2 is screwed into the first threaded hole 121. A through hole 211 is provided at the bottom of the mounting hole 21 of the rotating member 2. Therefore, the notch 111 is communicated with the mounting hole 21. When the vacuum device generates a vacuum suction force, the vacuum suction force can be transmitted to the mounting hole 21 through the notch 111, realizing the vacuum adsorption of the lens to be tested 100 in the mounting hole 21.

[0042] Optionally, asFigure 3 As shown, the rotating member 2 includes a second connecting portion 22 and a cap 23 that are coaxially aligned and connected to each other. The diameter of the cap 23 is larger than that of the second connecting portion 22.

The end face of the cap 23 facing away from the second connecting portion 22 is provided with a mounting hole 21 that extends to the second connecting portion 22. By providing the cap 23, when rotating the rotating member 2, the second connecting portion 22 can be driven to rotate by rotating the cap 23, making the operation more convenient.

[0043] To prevent the rotating member 2 from disengaging from the first threaded hole 121, the lens light detection device further includes a limiting member 3. The limiting member 3 is disposed on the first connecting portion 12 of the connecting base 1 and can limit the second connecting portion 22 from disengaging from the first threaded hole 121.

When the rotating member 2 is rotated to move away from the camera module board 200, the limiting member 3 can abut against the groove wall of the annular groove 221 to prevent the second connecting portion 22 of the rotating member 2 from disengaging from the first threaded hole 121.

[0045] Optionally, the limiting member 3 is a first screw, and the limiting hole is a second threaded hole. By screwing the first screw into the second threaded hole and the first screw extending into the annular groove 221, the rotating member 2 can be prevented from disengaging, and the structure is simple.

[0046] To facilitate the rotation of the cap 23, the outer peripheral wall of the cap 23 is provided with patterns. By providing patterns on the outer peripheral wall of the cap, the frictional resistance of the outer peripheral wall of the cap 23 can be increased, making the rotation more labor-saving.

[0047] To facilitate the use of the lens light detection device for light detection, the lens light detection device further includes a bracket 4. The camera module board 200 is installed on the bracket 4. By supporting the camera and the lens 100 to be measured through the bracket 4, the operation is made more convenient.

[0048] Specifically, the bracket 4 includes a first support plate 41, a second support plate 42, and a plurality of support columns 43. In this embodiment, four support columns 43 are provided. The four support columns 43 are connected between the first support plate 41 and the second support plate 42, and the four support columns 43 are respectively located at the four corner positions of the first support plate 41 and the second support plate 42. The camera module board 200 is installed on the first support plate 41, and the camera is located in the area between the first support plate 41 and the second support plate 42, and the structural layout is reasonable.

[0049] Furthermore, the lens lighting detection device further includes a pressing member 5. The first support plate 41 is provided with a through stepped counterbore. The camera module board 200 is installed in the stepped counterbore. The pressing member 5 is fixedly arranged on the first support plate 41 and presses against the camera module board 200, so that the camera module board 200 is stably installed. And through this structure, the installation of the camera module board 200 can be realized without opening holes in the camera module board 200. While realizing the connection between the camera module board 200 and the first support plate 41, it also avoids damaging the camera module board 200.

[0050] Optionally, the pressing member 5 includes a second screw 51 and a gasket 52. The gasket 52 is sleeved on the second screw 51. The second screw 51 is threadedly connected to the first support plate 41 and presses against the gasket 52. The edge of the gasket 52 presses against the camera module board 200. In this embodiment, there are four pressing members 5, and the four pressing members 5 respectively press against the four corner positions near the camera module board 200.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
