[0019] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0020] like Figure 1 As shown, an optical performance testing device includes a substrate 1 and a mounting frame 2. The mounting frames 2 are symmetrically arranged at the top of the substrate 1. A spotlight 3 and a light intensity sensor 4 are respectively arranged at the top of the two mounting frames 2. The spotlight 3 and the light intensity sensor 4 are concentrically arranged. A lens mounting assembly 5 is arranged in the middle of the top of the substrate 1. A driving assembly 6 for driving the two mounting frames 2 to move synchronously is arranged at the bottom of the substrate 1. A support base 11 is symmetrically arranged at the bottom end of the substrate 1.

[0021] According to the above structure, when in use, the lens is placed on the lens mounting assembly 5, and a light beam is emitted by the spotlight 3 through the lens mounting assembly 5. The light intensity sensor 4 receives the light beam, detects the light intensity of the light beam, and sends the detection signal to the computer of the peripheral device to analyze the light transmission performance of the lens. When in use, the positions of the two mounting brackets 2 are adjusted back and forth by the drive assembly 6 to detect different positions of the lens.

[0022] like Figure 1 and 2 As shown, the mounting bracket 2 includes an arched frame 21, with a mounting head 22 fixedly connected to the top of the arched frame 21. The top of the mounting head 22 is provided with a V-groove, and a pressure cap 23 is provided at the top of the mounting head 22. Screws 24 are symmetrically arranged at the top of the mounting head 22, and both screws 24 penetrate the pressure cap 23. Nuts for tightening the pressure cap 23 are provided on the side wall of the screws 24.

[0023] According to the above structure, when in use, the light intensity sensor 4 and the lens mounting assembly 5 are placed in the V-shaped groove at the top of the corresponding mounting bracket 2, and the light intensity sensor 4 and the lens mounting assembly 5 are pressed and fixed by the pressure cap 23.

[0024] like Figure 2-4 As shown, the lens mounting assembly 5 includes a support frame 51 fixedly connected to the middle of the top of the substrate 1. A cylinder 52 is rotatably connected to the top of the support frame 51. The side wall of the cylinder 52 is fixedly connected to guide cylinders 53 that are evenly distributed. A support rod 54 is slidably connected inside the guide cylinder 53. A first spring 56 is sleeved on the side wall of the support rod 54. The two ends of the first spring 56 are fixedly connected to the inner wall of the guide cylinder 53 and the side wall of the support rod 54, respectively. A U-shaped plate 55 is fixedly connected to one end of the support rod 54.

[0025] According to the above structure, when installing the lens, by clamping the U-shaped plate 55 on the side of the lens, under the elastic force of the first spring 56, the support rod 54 moves towards the center of the lens to squeeze the lens. Through the cooperation of several U-shaped plates 55, the lens is pressed tightly inside the cylinder 52. During the test, by rotating the cylinder 52, the light beam is shone through different positions of the lens, and thus different positions of the lens can be tested.

[0026] like Figure 3 and 4 As shown, the drive assembly 6 includes a first slide rail 61 fixedly connected to the middle of the bottom end of the substrate 1. A lead screw 62 is rotatably connected inside the first slide rail 61, and a slider 63 is slidably connected inside the first slide rail 61. The lead screw 62 and the slider 63 are threadedly connected. Connecting plates 64 are fixedly connected to both sides of the slider 63. A second slide rail 65 is symmetrically arranged at the top of the substrate 1. A support block 66 is slidably connected inside the second slide rail 65. The bottom end of the arched frame 21 is fixedly connected to the top end of the support block 66. A second spring 67 is arranged inside the support block 66. One end of the second spring 67 is fixedly connected to one end of the inner wall of the second slide rail 65. A push rod 68 is slidably connected to the other end of the second slide rail 65. One end of the push rod 68 is fixedly connected to one end of the support block 66. An L-shaped plate 69 is fixedly connected to the other end of the push rod 68. One end of the L-shaped plate 69 is fixedly connected to one end of the corresponding connecting plate 64.

[0027] According to the above structure, during testing, the slider 63 is driven to move back and forth by rotating the lead screw 62. Through the transmission of the two connecting plates 64, the two L-shaped plates 69 are driven to move back and forth. The two L-shaped plates 69 drive the two push rods 68 to move. The two push rods 68 drive the two support blocks 66 to move, thereby making the two mounting brackets 2 move synchronously. Thus, after adjusting the position of the spotlight 3 and the light intensity sensor 4, the spotlight 3 and the light intensity sensor 4 can still be kept concentric.

[0028] The working principle of this utility model is as follows: In use, the lens is placed on the lens mounting assembly 5. A beam of light is emitted by the spotlight 3, passing through the lens mounting assembly 5. The light intensity sensor 4 receives the beam and detects its intensity, sending the detection signal to the peripheral computer to analyze the lens's light transmission performance. During use, the positions of the two mounting brackets 2 are adjusted back and forth by the drive assembly 6 to detect different positions of the lens. The light intensity sensor 4 and the lens mounting assembly 5 are placed in the V-shaped grooves at the top of the corresponding mounting brackets 2. The pressure cap 23 presses and fixes the light intensity sensor 4 and the lens mounting assembly 5. When installing the lens, the U-shaped plate 55 is clipped onto the side of the lens, and the first spring 56... Under the elastic force, the support rod 54 moves towards the center of the lens and squeezes the lens. Through the cooperation of several U-shaped plates 55, the lens is pressed tightly inside the cylinder 52. During the test, the cylinder 52 is rotated so that the light beam passes through different positions of the lens, and different positions of the lens can be tested. During the test, the slider 63 is driven to move back and forth by rotating the lead screw 62. Through the transmission of the two connecting plates 64, the two L-shaped plates 69 are driven to move back and forth. The two L-shaped plates 69 drive the two push rods 68 to move. The two push rods 68 drive the two support blocks 66 to move, so that the two mounting brackets 2 move synchronously. Thus, after adjusting the position of the spotlight 3 and the light intensity sensor 4, the spotlight 3 and the light intensity sensor 4 can still be kept concentric.

[0029] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
