[0034] like Figures 1 to 3 As shown, a camera module high temperature test fixture includes a fixture base 4, a module mounting seat 3, an insulation cover plate 1, a module fixing handle 2, a heating tube 5 and a thermocouple 6.
[0035] The module mounting seat 3 includes a receiving groove 10, which is provided on the upper surface of the module mounting seat 3. The receiving groove 10 is used to receive the camera module 13 to be tested. By providing the receiving groove 10, the contact area with the camera module 13 to be tested can be increased, the heat transfer can be increased, and the heating effect of the camera module 13 to be tested can be improved. The bottom of the module mounting seat 3 is connected to the fixture base 4, and the fixture base 4 is convenient for installing the fixture on the test device or machine. The thermal insulation cover plate 1 is rotatably connected to the top of the module mounting seat 3.
[0036] The module fixing handle 2 is arranged on the module mounting seat 3 and is located on the periphery of the receiving groove. The module fixing handle 2 is used to fix the camera module 13 to be tested that is arranged in the receiving groove 10. The module fixing handle 2 can be an elastic structure that can be lifted and retracted. When the camera module 13 to be tested is placed in the receiving groove 10, the module fixing handle 2 is lifted to the top of the camera module 13 to be tested. After the module fixing handle 2 is released, the module fixing handle 2 will be pressed on the camera module 13 to be tested, playing the role of fixing the camera module 13 to be tested, and ensuring that the module will not be offset during the test process.
[0037] The heating tube 5 is arranged on the module mounting seat 3 and located at the bottom of the receiving groove 10, and is used to heat the camera module 13 to be tested;
[0038] The thermocouple 6 is arranged on the module mounting base 3 and is used to detect the temperature of the camera module 13 to be tested, to ensure that the temperature of the camera module 13 to be tested is within the test requirement range, and to facilitate the judgment of whether the heating tube 5 is turned on or off.
[0039] In order to facilitate the installation and positioning of the camera module, the module mounting seat 3 is provided with a positioning column 9, which protrudes from the upper surface of the module mounting seat 3. The camera module to be tested 13 is provided with a connecting seat 14, and the connecting seat 14 is provided with a through hole that cooperates with the positioning column 9. The connecting seat 14 can be a lug-shaped structure. The positioning column 9 facilitates the installation of the camera module to be tested 13 into the fixture, thereby improving the installation efficiency and installation accuracy.
[0040] In order to prevent the insulation cover plate 1 from being misaligned with the module mounting seat 3 after being buckled, a limiting column 8 is provided on the module mounting seat 3, and a limiting hole 11 is opened on the insulation cover plate 1 facing the module mounting seat 3, and the limiting column 8 and the limiting hole 11 are arranged in a one-to-one correspondence.

Magnets are provided in the first magnet receiving groove 7 and the second magnet receiving groove 12, and the magnets in the two receiving grooves can be adsorbed together.
[0042] More specifically, a through hole is provided on the thermal insulation cover plate 1 corresponding to the position of the camera module 13 to be tested, and the top of the camera module 13 to be tested protrudes out of the surface of the thermal insulation cover plate 1 through the through hole, so as to facilitate the test of the camera module installed on the fixture.
[0043] More specifically, the module mounting base 3 is made of aluminum alloy, which is convenient for heat transfer and allows the entire module mounting base 3 to heat evenly. The thermal insulation cover plate 1 is made of polyetheretherketone (PEEK) material, which can reduce the heat conduction and cooling of the module.
[0044] like Figure 4 As shown, the utility model also provides a camera module high temperature testing device, including the above-mentioned camera module high temperature testing fixture, as well as an oven 15, an adapter plate 16 and a test box 17.

The test box 17 is used to test the camera module 13 to be tested.
[0045] During operation, the camera modules 13 to be tested are first put into the oven 15 in batches for baking to preliminarily heat the camera modules 13 to be tested. At the same time, the camera module high-temperature test fixture 18 controls the fixture temperature to the required temperature through the heating tube 5 and the thermocouple 6. Then, the camera modules to be tested that have completed the preliminary heating are taken out of the oven one by one, installed and fixed in the camera module high-temperature test fixture 18, and the thermal insulation cover 1 on the camera module high-temperature test fixture 18 is covered to ensure that the temperature of the camera module 13 to be tested is controlled within a certain temperature range. The camera module 13 to be tested is electrically connected to the adapter plate 16, and the resolution of the camera module 13 to be tested is tested in a high temperature environment through the test box 17.
[0046] The above-mentioned embodiments only express several implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent of the utility model.
