Description

Technical Field

[0001] This utility model relates to the field of optical module aging monitoring technology, and in particular to an aging monitoring device for optical modules. Background Technology

[0002] Optical module aging monitoring refers to the continuous performance monitoring of optical modules throughout their service life to assess their aging status over time. This monitoring helps to detect optical modules with degraded performance or those that are about to fail in a timely manner, thereby enabling preventive measures to be taken to avoid system downtime or other problems caused by optical module failure.

[0003] Patent CN212844933U discloses an aging test chamber for electronic components. It includes a chassis, with the other end of each connecting rod penetrating a fixed plate and fixedly connected to a clamping plate. The outlet of a booster pump passes through a pipe connecting a water tank to the chassis and is connected to a water collection plate. An electric heating plate is installed at the top inside the chassis, and a UV lamp is installed at the bottom of the heating plate. An exhaust fan is installed at the bottom left end of the UV lamp. A temperature and humidity sensor is installed on the right inner wall of the chassis, and the sensor is connected to a processor via a signal line passing through the chassis. Using this patent, an optical module is placed on the fixed plate, and the air inside the test chamber is heated by the electric heating plate to perform an aging test on the optical module. However, this existing patent still has some problems in practical use. Because the electric heating plate in the existing patent is installed at the top inside the chassis, the hot air in the chassis tends to concentrate at the top, resulting in uneven heating of the optical module and causing deviations in the aging test results.

[0004] Therefore, there is a need to provide an aging monitoring device for optical modules with uniform heating function. Utility Model Content

[0005] To overcome the shortcomings of the existing patented heating plate, which is installed at the top of the chassis and causes hot air to concentrate in the upper part of the chassis, resulting in uneven heating of the optical module and deviations in aging test results, this utility model provides an aging monitoring device for optical modules with uniform heating function, through components such as an air guide tube, a first air supply pipe, and a second air supply pipe.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: an aging monitoring device for optical modules, comprising a test box, hinges, a protective door, a control panel, support rails, a placement plate, an aging test socket, and an optical module. Multiple hinges are installed on the test box, and a protective door is hinged between two hinges on the same side. The control panel is installed on the test box, and multiple support rails are fixedly connected inside the test box. A placement plate is slidably mounted on two support rails on the same horizontal line. Three sets of aging test sockets are installed on the placement plate, and an optical module is secured within each aging test socket. The device also includes a fan, an electric heating element, a first partition, a second partition, and a first air supply box. The test chamber consists of a second air supply box, an air guide pipe, an air guide cylinder, a first air supply pipe, and a second air supply pipe. Multiple fans and an electric heating element are installed on the test chamber. The control panel is electrically connected to the electric heating element and the fans. A first air supply box and a second air supply box are fixedly connected inside the test chamber. The second air supply box is located between the placement plate and the electric heating element. A first partition is fixedly connected between the second air supply box and the test chamber. A second partition is fixedly connected between the first and second air supply boxes. An air guide pipe is connected to and communicates with the first partition. An air guide cylinder is connected to the air guide pipe. A second air supply pipe is connected between the air guide cylinder and the second air supply box. A first air supply pipe is connected to the air guide cylinder.

[0007] As a further preferred embodiment, it also includes a motor, a turntable, a connecting rod, a slide rod, and a piston. The motor is mounted on the first partition, the turntable is mounted on the output shaft of the motor, the connecting rod is rotatably mounted on the turntable, the slide rod is rotatably mounted on the connecting rod, and the piston is fixedly connected to the slide rod.

[0008] As a further preferred embodiment, it also includes guide rods, push plates, clamping plates, limiting rings, and elastic elements. Two guide rods are fixedly connected to the placement plate, and three push plates are slidably arranged between the two guide rods. Three sets of clamping plates are fixedly connected to the push plates, and the optical module is located in the adjacent set of clamping plates. Two limiting rings are fixedly connected to the guide rods, and two elastic elements are sleeved on the guide rods. The two ends of the elastic elements are respectively connected to the limiting rings and the adjacent push plates.

[0009] As a further preferred option, a fixing rod is also included, with the two push plates being fixedly connected by a fixing rod.

[0010] As a further preferred option, it also includes limiting plates, with two limiting plates fixedly connected to the aging test fixture.

[0011] As a further preferred option, it also includes a heat insulation board, with the heat insulation board fixedly connected to the first partition.

[0012] As a further preferred option, an observation window is also included, with the observation window embedded in the protective door.

[0013] As a further preferred option, a dust filter is also included, with a dust filter installed on the fan.

[0014] Compared with the prior art, the present invention has the following technical effects: 1. By controlling the face to start the electric heating tube and fan, the fan draws outside air into the test chamber, so that it absorbs the heat on the electric heating tube, forming hot air and storing it in the air guide tube. The hot air then enters the first air supply pipe and the second air supply pipe through the air guide tube, and is finally discharged from the first air supply box and the second air supply box. In this way, hot air can be delivered from both the top and bottom of the test chamber at the same time, so that the optical module is heated evenly, thereby ensuring the test accuracy.

[0015] 2. By starting the motor, the motor's output shaft drives the turntable to rotate. The rotation of the turntable drives the connecting rod to rotate. The rotation of the connecting rod drives the slide rod and piston to move. The piston intermittently blocks the air vents between the first air supply pipe and the second air supply pipe and the air guide cylinder, controlling the flow and distribution of hot air, so that the heat in the test chamber is more uniform.

[0016] 3. By placing the optical module on the placement plate, positioning it between two clamping plates in a set, and then releasing the push plate, the elastic element drives the three push plates and two fixing rods to reset. While resetting, the push plates push all the optical modules to the left. The limiting plate can guide the optical modules and make them snap into the aging test socket, thus completing the optical module insertion at the same time, speeding up the test start time and ensuring test efficiency.

A control panel 4 is installed on the upper front of the test box 1, located above the protective door 3. Four support rails 5 are evenly spaced and welded to the upper left and right sides of the test box 1. Sliding mechanisms are installed on two support rails 5 on the same horizontal line. The test chamber 1 is equipped with a placement plate 6, on which three sets of aging test holders 601 are evenly spaced. Each set consists of three aging test holders 601 arranged on the same horizontal line. An optical module 7 is installed inside each aging test holder 601. The chamber also includes a fan 8, an electric heating element 9, a first partition 10, a second partition 11, a first air supply box 12, a second air supply box 13, an air guide pipe 14, an air guide cylinder 15, a first air supply pipe 16, and a second air supply pipe 17. Four fans are evenly spaced at the lower rear side of the test chamber 1 and connected by bolts. 8. An electric heating element 9 is installed on the lower rear side of the test chamber 1. The control panel 4 is electrically connected to the electric heating element 9 and the fan 8. The electric heating element 9 is located in front of the four fans 8. The first partition 10 is located in front of the electric heating element 9. A first air supply box 12 is fixedly connected to the top of the test chamber 1. A second air supply box 13 is fixedly connected to the middle of the test chamber 1. The second air supply box 13 is located between the placement plate 6 and the electric heating element 9. The first partition 10 is fixedly connected between the second air supply box 13 and the test chamber 1. The first partition 10 is located in front of the electric heating element 9. The first air supply box 12... A second partition 11 is fixedly connected to the second air supply box 13. The second partition 11 is located behind the placement plate 6. A duct 14 is connected to and communicates with the front side of the first partition 10. A duct cylinder 15 is connected to the front side of the duct 14. A second air supply pipe 17 is connected between the duct cylinder 15 and the second air supply box 13. A first air supply pipe 16 is connected to the duct cylinder 15. The first air supply pipe 16 passes through the second air supply box 13, and the end of the first air supply pipe 16 is located inside the first air supply box 12. Multiple ventilation holes are opened at the bottom of the first air supply box 12 and the top of the second air supply box 13.

[0027] See Figure 7 As shown, it also includes a limiting plate 29. The aging test base 601 is symmetrically and fixedly connected to the limiting plate 29 on the front and back sides. The limiting plate 29 is located on the front and back sides of the optical module 7.

[0028] See Figure 4 and Figure 5 As shown, it also includes a heat insulation plate 30, and the heat insulation plate 30 is fixedly connected to the rear side of the first partition 10.

[0029] See Figure 1 As shown, it also includes an observation window 31, which is embedded in the protective door 3.

[0030] See Figure 3 As shown, it also includes a dustproof net 32, which is installed on the fan 8 and is located behind the fan 8.

[0031] When performing an aging test on the optical module, first open the protective door 3, pull out the placement plate 6, then place the optical module 7 on the placement plate 6 and insert the optical module 7 into the aging test holder 601. After placement, push the placement plate 6 back into its original position and close the protective door 3. The testing process inside the test chamber 1 can be observed through the observation window 31. During the test, the electric heating tube 9 and fan 8 are activated by controlling the faceplate. The electric heating tube 9 converts electrical energy into heat energy, and the fan 8 draws outside air into the test chamber 1. The dustproof net 32 ​​can prevent external debris from getting stuck. The fan 8 absorbs the heat from the electric heating tube 9, and the heat insulation plate 30 prevents the heat from the electric heating tube 9 from dissipating. The hot air is stored in the air delivery cylinder 15 through the air delivery pipe 14. The hot air then enters the first air delivery pipe 16 and the second air delivery pipe 17 through the air delivery pipe 15, and is finally discharged from the first air delivery box 12 and the second air delivery box 13. This allows hot air to be delivered from both the top and bottom of the test box 1 at the same time, so that the optical module is heated evenly, thereby ensuring the test accuracy.

[0032] Example 2: Based on Example 1, refer to Figure 4 and Figure 6 As shown, it also includes a motor 18, a turntable 19, a connecting rod 20, a sliding rod 21, and a piston 22. The motor 18 is bolted to the front side of the first partition 10. The motor 18 is located to the left of the air guide cylinder 15. The turntable 19 is mounted on the output shaft of the motor 18. The connecting rod 20 is rotatably mounted on the front right side of the turntable 19. The sliding rod 21 is rotatably mounted at the end of the connecting rod 20. The sliding rod 21 slides on the air guide cylinder 15. The piston 22 is fixedly connected to the end of the sliding rod 21 and is located inside the air guide cylinder 15.

[0033] When hot air is being delivered, the motor 18 is started, and the output shaft of the motor 18 drives the turntable 19 to rotate. The rotation of the turntable 19 drives the connecting rod 20 to rotate, and the rotation of the connecting rod 20 drives the slide rod 21 to slide on the air guide cylinder 15. As the slide rod 21 moves, it drives the piston 22 to move, so that the piston 22 intermittently blocks the air vent between the first air supply pipe 16, the second air supply pipe 17, and the air guide cylinder 15, effectively controlling the flow and distribution of hot air, making the heat in the test chamber 1 more uniform. After the test is completed, the motor 18 can be turned off.

[0034] See Figure 7As shown, it also includes guide rods 23, push plates 24, clamping plates 25, limiting rings 26, and elastic elements 27. Guide rods 23 are symmetrically fixed to the top of the placement plate 6. Three push plates 24 are evenly spaced and slidably arranged between the two guide rods 23. The push plates 24 are located to the right of the adjacent aging test seat 601. Three sets of clamping plates 25 are evenly spaced and fixed to the left side of the push plates 24. Two clamping plates 25 form a group. The optical module 7 is located in the adjacent set of clamping plates 25. Limiting rings 26 are fixedly connected to both ends of the guide rods 23. Elastic elements 27 are sleeved on both the left and right sides of the guide rods 23. The two ends of the elastic elements 27 are connected to the limiting rings 26 and the adjacent push plates 24, respectively.

[0035] See Figure 7 As shown, it also includes a fixing rod 28, which is fixedly connected between the two push plates 24. The three push plates 24 can be moved simultaneously through the fixing rod 28.

[0036] When the optical module 7 needs to be placed in front of the placement plate 6, first pull one of the push plates 24 to the right. At the same time, the other two push plates 24 are moved by the fixing rod 28, and the elastic element 27 is compressed. Then, place the optical module 7 on the placement plate 6 so that it is located between the two clamping plates 25 of a set. Then, by releasing the push plate 24, the elastic element 27 drives the three push plates 24 and the two fixing rods 28 to reset. While the push plate 24 is resetting, it pushes all the optical modules 7 to the left. The limiting plate 29 can guide the optical module 7 so that it is inserted into the aging test socket 601. In this way, the optical module 7 can be inserted at the same time, which speeds up the test start time and ensures the test efficiency. After the test is completed, the optical module 7 can be removed.
