[0039] Compared with the prior art, the present invention has the following beneficial technical effects:

[0040] This invention provides a lens testing fixture that facilitates angle and displacement adjustment. Through the inclusion of a lens displacement component and a light source plate displacement component, the positions of the lens and light source plate can be easily adjusted, enabling testing to cover more scenes and angles. The design of the lifting angle adjustment support platform and lifting angle adjustment device allows the lens assembly to be easily tested at different angles, improving testing accuracy and practicality. The lens end of the lens assembly is aligned with several target components of the light source plate displacement components, ensuring testing accuracy and precision, and helping to identify performance differences of the lens under different conditions. This invention enables multi-degree-of-freedom movement, meeting testing needs in complex environments, and features automatic lens orientation adjustment and automatic center alignment, as well as automatic target switching, improving testing efficiency and accuracy.

[0041] Furthermore, the high-precision displacement movement of the lifting angle adjustment support platform is achieved through the cooperation of the first displacement screw and the first displacement track, ensuring stable movement of the lens during testing. The inclusion of a first drive motor automates the displacement process, significantly reducing the need for manual operation. By communicating with the controller, the first drive motor receives commands and moves precisely according to preset parameters, improving the automation and efficiency of the testing process.

[0042] Furthermore, through the precise cooperation between the second displacement screw and the second displacement track, the light source board sliding assembly can perform high-precision and stable displacement movement along the track. This ensures that the target assembly can accurately reach the predetermined position during testing, providing a reliable benchmark for lens testing. The introduction of the second drive motor enables automated control of the light source board's displacement movement. By communicating with the controller, the second drive motor can receive commands and move precisely according to preset parameters without manual intervention, greatly improving the efficiency and accuracy of the testing process.

[0043] Furthermore, the tight connection between the light source plate moving slider and the second displacement moving screw ensures the stability of the light source plate during displacement. This avoids potential shaking or deviation of the light source plate during movement, thereby improving the accuracy of the test. Through precise control of the second displacement moving screw, the light source plate moving slider can perform high-precision displacement movement along the second displacement moving track. This high-precision positioning capability enables the target assembly to accurately reach the predetermined position, providing a reliable reference point for lens testing.

[0044] Furthermore, the tight connection between the support platform slider and the first displacement screw ensures the stability of the support platform during displacement. This avoids potential swaying or deviation during movement, thus guaranteeing the stability and accuracy of the lifting angle adjustment device and the lens assembly mounted on it. The lifting angle adjustment device is located on the end face of the support platform, allowing the lens assembly to be tested at different angles. This not only improves testing flexibility but also achieves high-precision positioning of the lens assembly during angle adjustment through the stable support of the support platform.

[0045] Furthermore, the angle adjustment component is tightly connected to the lens assembly via a lens mounting slider, enabling high-precision angle adjustment of the lens assembly. This ensures that the lens assembly can accurately align with the target during testing, improving the accuracy and reliability of the test. The lifting component is mounted on the support frame, and the lens mounting slider is slidably connected to the lifting component, allowing the lens assembly to be adjusted not only vertically but also horizontally via the displacement of the support platform. This flexibility allows the lens assembly to adapt to the needs of different testing scenarios, improving the applicability of the test. The support frame, as the basic support structure of the lifting angle adjustment device, ensures the stability and reliability of the entire device. The sliding connection design between the lens mounting slider and the lifting component ensures that the lens assembly maintains a stable posture during adjustment, avoiding test errors caused by shaking or deviation.

[0046] Furthermore, the third drive motor, by driving the third displacement bolt, achieves precise lifting and lowering control of the lens mounting slider. This ensures accurate adjustment of the lens assembly's vertical position, improving the accuracy and reliability of the test. The two ends of the lens mounting slider are slidably mounted on two sets of displacement sliding grooves, providing a stable lifting track and preventing swaying or deviation of the lens assembly during lifting. Simultaneously, the moving fixing component is fitted onto the third displacement bolt and fixed to the lens mounting slider via the displacement sliding grooves, enhancing the stability of the lifting process.

[0047] Furthermore, the nut is threaded onto the third displacement bolt, ensuring a stable connection between the lens mounting slider and the third displacement bolt. The movement of the nut on the bolt precisely controls the height of the lens mounting slider while providing sufficient support to prevent swaying or tilting of the lens assembly during lifting. Connecting rods are located on both sides of the nut, and these connecting rods are fixed to the lens mounting slider via displacement grooves. This not only increases the overall structural stability of the lifting assembly but also ensures the smooth operation of the lens mounting slider during lifting. The connecting rods serve as guides and fixation, preventing the lens mounting slider from shifting or twisting during lifting.

[0048] Furthermore, the fourth drive motor, by driving the rotating shaft, enables high-precision angle adjustment of the lens assembly. This ensures the lens assembly can rotate accurately within the horizontal plane, meeting the requirements for different angles during testing. High-precision angle adjustment is crucial for lens performance testing, as it directly affects the accuracy and reliability of the test results. The robust connection design between the rotating shaft, the lens mounting slider, and the lens assembly ensures the stability of the lens assembly during rotation. This design avoids potential wobbling or deviation during lens assembly rotation, thus guaranteeing the accuracy and consistency of the test.

[0049] Furthermore, the controller incorporates a control module. This module receives signals from the lens assembly via a signal input module and controls the first, second, third, and fourth drive modules via a signal output module. This achieves a high degree of integration and automation of the test fixture, reducing the complexity of manual operation and improving testing efficiency and accuracy. The control module can precisely control the output of each drive module, ensuring coordinated operation between the lens displacement component, the light source board displacement component, and the lifting angle adjustment device. By adjusting the parameter settings in the control module, users can flexibly configure the operating mode of the test fixture to meet the needs of different lenses and testing scenarios. This flexibility allows the test fixture to be applied to a wider range of lens tests, improving its applicability. Attached Figure Description
