Description

Technical Field

[0001] This utility model relates to the field of optical module manufacturing and processing technology, and in particular to a high-temperature aging test device for optical modules. Background Technology

[0002] An optical module is a core component used in optical communication, primarily responsible for converting between optical and electrical signals. High-temperature aging tests are a crucial step in ensuring the long-term reliability and stability of optical modules. The main purpose is to simulate extreme operating conditions to expose potential defects early and identify products that fail prematurely.

[0003] A high-temperature aging test device for optical module production disclosed in Chinese patent CN217360088U includes a body with a test chamber inside. A heating plate is fixedly installed on the inner wall and bottom of the test chamber, and an electric heating wire is fixed on the surface of the heating plate. Two sets of supports are arranged inside the test chamber, and a shelf is detachably installed between the two sets of supports. A rapid cooling mechanism is arranged inside the body, and a uniform cooling mechanism is arranged on the top of the test chamber.

[0004] However, this testing device still has the following problems in actual use:

[0005] When in use, the testing device uses the rotation of fan blades to drive the airflow in the testing chamber. However, the airflow is blocked by the shelves, resulting in a temperature difference between the optical modules on the shelves closer to the high-temperature air intake pipe and those farther away. This uneven temperature distribution in the testing chamber affects the consistency of the test results. Furthermore, some optical modules on shelves farther away from the high-temperature air intake pipe may not reach the set aging temperature, thus affecting the accuracy of the test results and making it impossible to effectively screen out early-failure products.

[0039] like Figure 3 and Figure 6 As shown, the placement component 4 includes a gear ring 401, a connecting post 402, a placement plate 403, a transition plate 404, and a moving part 405. The gear ring 401 is rotatably connected to the top inside the housing 1. The transmission gear 101 meshes with the gear ring 401. The bottom of the gear ring 401 is fixedly connected to the connecting post 402. The placement plate 403 is fixedly connected to the connecting post 402. There are multiple placement plates 403, which are linearly arrayed on the connecting post 402. The transition plate 404 is fixedly connected between the connected placement plates 403. The end of the connecting post 402 away from the gear ring 401 is provided with a moving part 405. The connecting post 402 is movably connected to the housing 1 through the moving part 405. In this embodiment, the moving part 405 includes a connecting block fixedly connected to the connecting post 402. The bottom of the connecting block is provided with a ball. In other embodiments, the moving part 405 can also be a caster wheel or a roller, etc.

[0040] like Figure 5 and Figure 7 As shown, the air intake assembly 31 includes a connecting pipe 311, a three-way pipe 312, a hot air intake pipe 313, a cold air intake pipe 314, and a rotary joint 315. One end of the connecting pipe 311 is fixedly connected to the three-way pipe 312. Valves are provided at the three connection ports of the three-way pipe 312. The two ends of the three-way pipe 312 away from the connecting pipe 311 are respectively fixedly connected to the hot air intake pipe 313 and the cold air intake pipe 314. The end of the connecting pipe 311 away from the three-way pipe 312 is provided with a rotary joint 315. The connecting pipe 311 is rotatably connected to the air distribution pipe 32 through the rotary joint 315.

[0041] like Figure 5 , Figure 8 and Figure 9 As shown, one end of the air distribution pipe 32 is fixedly connected to a drive gear 321, which meshes with the transmission gear 101. The gear ring 401 is connected to the drive gear 321 via the transmission gear 101. The air distribution pipe 32 is provided with an air outlet 322. There are multiple air outlets 322. The number of disturbance components 33 is the same as the number of air outlets 322. A connecting frame 323 is fixedly connected inside the air outlet 322.

[0042] like Figure 5 , Figure 9 and Figure 10 As shown, the disturbance component 33 includes a rotating component 331 and a disturbance blade 332. The rotating component 331 is rotatably connected to the inside of the air outlet 322 through a connecting frame 323. The disturbance blade 332 is fixedly connected to the rotating component 331. There are multiple disturbance blades 332, which are distributed in a circumferential array on the rotating component 331.

[0043] The work process is as follows:

[0044] S1. When using, first open the side door 102, place the optical module to be tested on the placement plate 403, and then close the side door 102.

[0045] S2. Start the drive unit 2. The drive unit 2 drives the air distribution pipe 32 to rotate. The air distribution pipe 32 drives the disturbance component 33 and the drive gear 321 to rotate. The drive gear 321 drives the gear ring 401 to rotate through the transmission gear 101. The rotation direction of the gear ring 401 is opposite to the rotation direction of the drive gear 321. The gear ring 401 drives the placement plate 403 to rotate through the connecting column 402. The placement plate 403 drives the optical module placed on it to rotate.

[0046] S3. Open the valves on the three-way pipe 312 near the connecting pipe 311 and near the hot air inlet pipe 313. Hot air enters from the hot air inlet pipe 313 and enters the air distribution pipe 32 through the three-way pipe 312, the connecting pipe 311 and the rotary joint 315.

[0047] S4. Then, the hot air is blown out from the outlet 322. The hot air flow blows the disturbance blade 332 to rotate, disturbing the hot air flow blown out from the outlet 322. This ensures the uniformity of the temperature distribution inside the casing 1, ensures the accuracy of the test results, and facilitates the effective screening of early failure products.

[0048] S5. At the same time, the hot air in the housing 1 can flow from between adjacent placement plates 403 to between other placement plates 403 at the transition plate 404, avoiding temperature differences in various parts of the internal space of the housing 1, thereby ensuring the consistency of the test results.

[0049] S6. After the test is completed, close the valve on the three-way pipe 312 near the hot air inlet pipe 313, and open the valve on the three-way pipe 312 near the cold air inlet pipe 314. The cold air enters from the cold air inlet pipe 314 and enters the air distribution pipe 32 through the three-way pipe 312, the connecting pipe 311 and the rotary joint 315.

[0050] S7. Then, the hot air is blown out from the air outlet 322. The hot air flow blows and disturbs the rotation of the disturbance blade 332, disturbing the hot air flow blown out from the air outlet 322 and uniformly cooling the inside of the casing 1. Then, the side door 102 can be opened to take out the tested optical module on the placement plate 403.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
