Abstract
Description
Technical Field

When testing an infrared module with a blackbody, the module's optical lens must be precisely aligned with the blackbody to ensure calibration accuracy. However, in existing testing equipment, the infrared module mounted on the fixture cannot be adjusted to correspond to the blackbody to achieve precise alignment. Inaccurate alignment may lead to deviations in calibration results, affecting the accuracy of temperature measurement in practical applications. Utility Model Content

The multi-degree-of-freedom adjustment mechanism 20 adjusts the infrared module 10 to precisely align with the blackbody assembly 50. The blackbody assembly 50 outside the temperature chamber 30 provides a radiation source at a standard temperature. The infrared module 10 is aligned with the blackbody assembly 50 through the multi-degree-of-freedom adjustment mechanism 20 for testing.
[0048] Please see Figure 3-6In one embodiment of the utility model, it further includes an electric indexing disk 31 disposed above the support platform 40 and a rotating disk 32 disposed on the electric indexing disk 31.

[0049] Please see Figure 3-6 In one embodiment of the utility model, a manual lifting platform 45 is further included, which is disposed above the support platform 40, and the electric indexing plate 31 is connected to the manual lifting platform 45. The manual lifting platform 45 allows the infrared module 10 to move along the Z-axis direction, and the infrared module 10 moves along the Z-axis direction to precisely align with the blackbody assembly 50.
[0050] Please see Figure 3-6 In one embodiment of the utility model, the support platform 40 includes a working base plate 41, reinforcing ribs 42 disposed below the working base plate 41, multiple support legs 43, and a handle 44 disposed above the working base plate 41.

[0051] Please see Figure 3-6 In one embodiment of the utility model, the blackbody assembly 50 includes a placement frame 52 and a plurality of blackbodies 51 disposed on the placement frame 52. Different blackbodies 51 are used to provide radiation sources at different temperatures. The blackbody assembly 50 includes a plurality of blackbodies 51, and different blackbodies 51 are used to provide radiation sources at high and low temperatures, thereby improving the measurement accuracy of the infrared module 10.
[0052] Please see Figure 3-6 In one embodiment of the utility model, the blackbody assembly 50 further includes a manually operated lifting platform 45 disposed on the placement frame 52 and corresponding to each of the blackbody 51.

[0053] To facilitate understanding of the above technical solutions of this application, the specific usage process of this infrared module testing system will be further explained below:
[0054] Step 1: Install the infrared modules 10. Specifically, manually install the eight infrared modules 10 one by one onto the eight multi-degree-of-freedom adjustment mechanisms 20 on the rotating disk 32.
[0055] Step 2: Coarse alignment adjustment. Specifically, manually adjust the manual lifting platform 45 above the support platform 40, and correspondingly manually adjust the manual lifting platform 45 on the placement rack 52 so that the eight infrared modules 10 on the rotating disk 32 are nearly aligned with one of the two black bodies 51 on the placement rack in the height direction.
[0056] Step 3: Fine alignment adjustment. Specifically, manual adjustment is used to rotate the infrared module 10 left and right in the Z-axis direction to change the orientation of the infrared module 10. The rotating seat 230 can be tightened by twisting the adjusting screw 232 to limit the rotation of the rotating seat 230, thereby locking the orientation of the infrared module 10. Combined with manual adjustment of the multi-angle adjustment hinge 242, the pitch angle of the infrared module 10 can be changed. With the help of rotating the rotating disk 32, all eight infrared modules 10 are precisely aligned with the aforementioned black body 51 on the placement rack in the height direction.
[0057] Step 4: The electric indexing plate 31 drives the eight infrared modules 10 on the rotating plate 32 to rotate. After switching different infrared modules 10 on the rotating plate 32 to align with the aforementioned black body 51, the infrared modules 10 are tested.
[0058] Step 5: Move the placement rack 52 so that the other black body 51 is nearly aligned with the eight infrared modules 10 on the rotating disk 32 in the height direction, and repeat steps 3 and 4 to complete the test of the infrared modules 10 after aligning the two black bodies 51 on the placement rack.
