[0062] Please see Figure 1-5In one embodiment of the utility model, a fixture 100 with a focusing mechanism includes a mounting base 60, a focusing connector 70, a driving assembly 80, and a transmission assembly 90. The mounting base 60 is equipped with an imaging module to be tested. The focusing connector 70 is positioned opposite to the imaging module to be tested and is connected to the focusing ring 71 of the imaging module to be tested. The driving assembly 80 is drivenly connected to the focusing connector 70. The transmission assembly 90 is connected between the driving assembly 80 and the focusing connector 70. Under the driving force provided by the driving assembly 80, the focusing connector 70 is driven to rotate, thereby driving the focusing ring 71 to rotate for focusing.

[0063] In the above-described solution of this application, a focusing connector 70 connected to the focusing ring 71 and a drive assembly 80 providing rotational force to the focusing ring 71 are provided. A transmission assembly 90 is also provided to transmit the rotational force provided by the drive assembly 80 to the focusing connector 70 to drive the focusing ring 71 to rotate and focus. The drive assembly 80 provides rotational driving force, and the transmission assembly 90 transmits the rotational driving force until it reaches the focusing connector 70. The focusing connector 70 rotates, and the rotation of the focusing connector 70 drives the focusing ring 71 to rotate and focus, thereby realizing automatic focusing of the imaging module under test (the imaging module can be an infrared thermal imager, which is one type of imaging module. The imaging module includes an infrared module 10, which includes an infrared thermal imager) mounted on the mounting base 60, meeting the need for rapid response in scenarios requiring frequent focusing.

[0064] Please see Figure 1-5 In one embodiment of the utility model, the focusing connector 70 includes a plurality of arc-shaped segments 72 spaced apart along the circumferential direction. Adjacent arc-shaped segments 72 are detachably connected, and the plurality of arc-shaped segments 72 together form the focusing connector 70 surrounding the outer circumferential surface of the focusing ring 71. In this fixture, the focusing connector 70 includes a plurality of arc-shaped segments 72 spaced apart along the circumferential direction, and adjacent arc-shaped segments 72 are detachably connected. Different arc-shaped segments 72 can be replaced to adapt to clamping focusing rings 71 with different outer diameters. The detachable connection can be achieved by bolt connection, ensuring a secure connection between the focusing connector 70 and the focusing ring 71.

[0065] Please see Figure 1-5 In one embodiment of the utility model, the transmission assembly 90 includes a driven column 91 and a rotating wheel 92. The rotating wheel 92 is provided with a drive groove 922. One end of the driven column 91 is connected to the focusing connector 70, and the other end is inserted into the drive groove 922 of the rotating wheel 92. By using the configuration of the driven column 91 and the rotating wheel 92, the focusing mechanism can achieve precise force transmission and rotational movement, thereby ensuring the precise rotational focusing of the focusing ring 71.

[0066] Please see Figure 1-5 In one embodiment of the utility model, the rotating wheel 92 includes a rotating cylindrical wall 920 and a bottom wall 921 disposed at one end of the rotating cylindrical wall 920. The rotating wheel 92 has a hole 923 inside, and the driving groove 922 is an oblong groove 924 disposed on the bottom wall 921, extending radially from the outer periphery of the hole 923. In this fixture, the driving groove 922 is an oblong groove 924 disposed on the bottom wall 921, which facilitates the flexible installation of the driven column 91 into the driving groove 922 of the rotating wheel 92, improving installation convenience.

[0067] Please see Figure 1-5 In one embodiment of the utility model, the driving groove 922 includes multiple grooves, which are evenly arranged on the bottom wall 921 relative to the axis of rotation of the bottom wall 921. The multiple driving grooves 922 facilitate the installation of the driven column 91 into the rotating wheel 92 from various positions, enabling force transmission and improving installation convenience.

[0068] Please see Figure 1-5 In one embodiment of the utility model, a drive fixing base 81 is further included. A receiving cavity 82 is provided on the drive fixing base 81 corresponding to the position of the imaging module under test. The transmission assembly 90 further includes a bearing 83, a first retaining ring 84, and a second retaining ring 85. The bearing 83 is disposed within the receiving cavity 82. The rotating cylinder wall 920 of the rotating wheel 92 passes through the inner ring of the bearing 83 and connects to the first retaining ring 84. The second retaining ring 85 is used to position the outer ring of the bearing 83. With the above structure, the rotating wheel 92 can stably rotate around its axis. When one end of the driven column 91 is connected to the focusing connector 70, and the other end is inserted into the drive groove 922 provided in the rotating wheel 92, when the rotating wheel 92 rotates, the drive groove 922 drives the driven column 91 to rotate. The focusing connector 70 connected to the driven column 91 rotates accordingly, and the rotation of the focusing connector 70 drives the focusing ring 71 to rotate for focusing.

[0069] Please see Figure 1-5 In one embodiment of the utility model, the drive assembly 80 includes a drive motor 86, a driving synchronous pulley 87, and a driven synchronous pulley 88 connected to the rotating wheel 92. The drive motor 86 is mounted on a drive mounting base 81. The driving synchronous pulley 87 is connected to the output shaft of the drive motor 86 and is connected to the driven synchronous pulley 88 via a synchronous belt 89. Using a synchronous belt 89 for transmission allows for stable force transmission and precise speed control. The elasticity and flexibility of the synchronous belt 89 also help reduce vibration and impact, improving the stability and lifespan of the focusing mechanism.

[0070] Please see Figure 1-5In one embodiment of the utility model, the drive mounting base 81 is provided with a motor mounting part, which includes spaced and parallel adjusting slots 810. The drive motor 86 is provided with a mounting through hole 860. Each adjusting slot 810 is provided with multiple fasteners (e.g., bolts). Each fastener passes through the adjusting slot 810 of the drive mounting base 81 and the mounting through hole 860 of the drive motor 86 in sequence and is connected to a nut. This allows for quick installation and fixing of the drive motor 86, and the elongated hole design of the adjusting slots 810 also allows for fine-tuning of the position of the drive motor 86 to adapt to different installation requirements.

[0071] Please see Figure 1-5 In one embodiment of the utility model, a tensioning mechanism is further included. The tensioning mechanism includes a mounting plate 811, a locking member 812 passing through the mounting plate 811, and a pressing part 813 located at the end of the locking member 812. The locking member 812 (which may be a screw) can move up and down relative to the mounting plate 811 in a direction perpendicular to the top surface of the drive motor 86. The pressing part 813 has a through hole 8130. Each fixing member sequentially passes through the adjusting groove 810 of the drive fixing seat 81 and the mounting through hole 860 on the drive motor 86, and then passes through the through hole 8130 on the pressing part 813 to connect with the nut. By adjusting the up and down movement of the locking member 812 relative to the mounting plate 811 in a direction perpendicular to the top surface of the drive motor 86, the tension of the synchronous belt 89 can be easily adjusted. The design of the tensioning mechanism ensures that the tension of the synchronous belt 89 is moderate, avoiding impact on transmission efficiency and lifespan due to excessive or insufficient tension.

[0072] Please see Figure 1-5 In one embodiment of the utility model, a fixed base plate 814 is provided on one side of the drive fixing seat 81. The fixed base plate 814 is connected to the side wall of the drive fixing seat 81 by a reinforcing rib 815, and the mounting seat 60 is disposed on the fixed base plate 814. By providing a fixed plate and reinforcing ribs, the rigidity and stability of the entire fixture can be improved, deformation caused by external forces can be reduced, and focusing accuracy can be ensured.

[0084] 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:

[0085] 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.

[0086] 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.

[0087] 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.

[0088] Step 4: The electric indexing plate 31 drives the eight infrared modules 10 on the rotating plate 32 to rotate. After switching the different infrared modules 10 on the rotating plate 32 to align with the aforementioned black body 51, each infrared module 10 automatically completes autofocus through the focusing mechanism, and then the infrared module 10 is tested.

[0089] 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.
