[0027] like Figures 1-2 As shown, this embodiment provides an automatic infrared optical axis detection device, including an infrared light source, a white light mirror 3, an image acquisition device, and an automatic rotation mechanism 2. The automatic rotation mechanism 2 includes a transition structure and an automatic rotation platform 21 for driving the infrared product under test to rotate around its axis. The transition structure is connected to the automatic rotation platform 21, and the transition structure has a mounting position for detachably installing the infrared product under test. The infrared light source, the mounting position, the automatic rotation platform 21, the white light mirror 3, and the image acquisition device are arranged coaxially in sequence. This embodiment enables the rapid disassembly and clamping of the infrared product under test on the automatic rotation platform 21 through the transition structure. By driving the infrared product under test to rotate around its axis through the automatic rotation platform 21, optical axis testing at different angles can be automatically performed. This not only saves manual operation time and improves production efficiency, but also provides high operational accuracy and good testing consistency. Furthermore, the device has strong applicability and high versatility.

[0028] In some embodiments, the adapter structure includes an adapter block 22 and an adapter ring 23 for detachably mounting the infrared product under test. The adapter block 22 is connected to the automatic rotating platform 21, and the adapter ring 23 is detachably connected to the adapter block 22.

Figure 1 As shown, the diffuse reflection collimator 1 is supported on the optical platform 8 by a bracket, and the diffuse reflection collimator 1 is directly facing the adapter structure extending from the second through hole, so that the infrared light emitted by the diffuse reflection collimator 1 can just illuminate the infrared product under test.

[0044] In this embodiment, the operator first connects the infrared product to be tested to the adapter ring 23 of the automatic rotating mechanism 2 via a thread, and sets the detection parameters through the touch screen 95 or a host computer. Then, the device is started, and the automatic rotating platform 21 rotates the infrared product to be tested to a specified angle according to a preset program, stopping at each angle to perform initial and re-measurements of the optical axis. Infrared light emitted by the diffuse reflection parallel light tube 1 illuminates the infrared product to be tested, then enters the white light mirror 3, which reflects the optical axis into the field of view of the CCD camera 4. The camera captures the image and transmits it to the host computer. The host computer adjusts the imaging effect using an adjustable slide to ensure a complete and clear image is projected onto the host computer. The host computer analyzes the image data, automatically determines the product's pass / fail status, and displays the detection results on the touch screen 95.
