Then the laser displacement sensor 69 on the laser calibration mechanism 6 is moved to the top of the device under test, and the laser displacement sensor 69 measures the height of the device under test. After the measurement is completed, the lifting mechanism 5 will drive the work table 4 upward or downward for height compensation according to the difference between the two measured heights, and finally make the plane of the device under test and the reference plane at the same height position; move the cross spot laser 68 on the laser calibration mechanism 6 to the center of the work table 4.

Start to move until the pressure reaches the clamping force value set by the corresponding pressure sensor 78, and the corresponding clamping assembly 72 stops moving. After all four clamping assemblies 72 stop moving, the device under test is clamped; then the four clamping assemblies 72 can be fine-tuned synchronously, and the test point of the device under test is moved to the cross-line center of the laser calibrator. At this time, the device under test has been aligned, and the cross-spot laser 68 returns to the initial position; turn on the light box 83, the light source generating box 82 moves upward to the specified position, and the rotating cylinder rotates the illuminance meter 86 to the bottom of the aperture 84 to test the light intensity of the light source, and adjust the aperture 84 to a suitable aperture; after the light intensity test is completed, the rotating cylinder rotates the illuminance meter 86 to the initial position, and the light source generating box 82 Move upward to the test position, and the large amount of heat generated by the lamp box 83 can be dissipated in time through the air inlet 87, the exhaust port 88, and the Heilock fan, so as to prevent overheating; then close the safety door 112 on the cabinet 111, and the safety grating 113 starts to work; then, the multi-axis rotation mechanism 3 and the XY axis operation mechanism 10 are linked to adjust the test point of the device under test to coincide with the center of the light source, and the magnetic rotary encoder 39 located on the Y-axis rotation support frame 31 detects the rotation angle consistency of the rotation frame 32 in real time, and the magnetic rotary encoder 39 located on the rotation frame 32 detects the rotation angle consistency of the X-axis rotation support frame 33 in real time, and the dual-axis inclination sensor 79 on the support base plate 71 will display the XY axis angle value of the work table 4 in real time, so as to ensure the level and rotation accuracy of the platform. At this time, the device under test and the light source are aligned;During the test, the multi-axis rotating mechanism 3 drives the device under test to rotate and swing in multiple directions of ±90°, so as to test the influence of light at different angles on the device under test, and each time the rotation and swing occurs, the magnetic rotary encoder 39 on the Y-axis rotating support frame 31 and the magnetic rotary encoder 39 on the rotating frame 32 will monitor and feedback the rotation angle in real time until the safety door 112 is opened, the device under test is taken out, and the test is completed; the present invention can perform all-round linkage testing on the camera, and can achieve fast and accurate alignment. ;
