Technical Field
[0001] This utility model relates to the technical field of optical module testing devices, and in particular to an optical module testing device capable of continuous testing. Background Technology
[0002] This optical module testing device aims to achieve continuous automated testing of various performance indicators of optical modules, improving testing efficiency and accuracy. It is suitable for quality inspection on optical module production lines or performance evaluation during the R&D process. II. Main Components The optical interface module includes input and output fiber optic connectors for establishing optical connections with the optical module under test. These connectors feature a high-precision alignment mechanism to ensure low-loss coupling between fibers. For example, LC-type fiber optic connectors are used, which are compact, easy to plug and unplug, and highly accurate, ensuring stable transmission of optical signals. An optical power monitoring unit is equipped to monitor input and output optical power in real time. A photodetector converts the optical signal into an electrical signal for subsequent analysis of parameters such as gain and loss of the optical module. For example, an InGaAs PIN photodiode is used as the detector, which has high sensitivity and a wide spectral response range, accurately measuring optical power at different wavelengths. The electrical interface module provides interfaces for electrical signal connection with the optical module, including power supply, data input / output pins, etc. It can provide stable operating voltage and current to the optical module and simultaneously receive the electrical signals output by the optical module for performance analysis. Equipped with signal generation and acquisition capabilities, it can generate various electrical signals required for testing, such as analog data signals and clock signals, and acquire and analyze the response signals of the optical module. For example, an arbitrary waveform generator can be used to generate electrical signals of different frequencies and amplitudes, and a high-speed digital sampling oscilloscope can be used to acquire the output electrical signals of the optical module to evaluate its electro-optical conversion performance and data transmission characteristics.
[0003] As a key component in fiber optic communication systems, the performance and quality of optical modules have a crucial impact on the stability and reliability of the entire communication system. However, traditional optical module testing devices mostly rely on manual operation or semi-automation, resulting in low testing efficiency and difficulty in achieving continuous testing, which cannot meet the needs of large-scale production. In addition, existing testing devices often damage optical modules when clamping and positioning them, affecting the accuracy of test results and the product's lifespan. Therefore, we propose a continuously testing optical module testing device to solve this problem. Utility Model Content

A rack is rotatably installed on one side of the connecting rod one. The two racks respectively mesh with the corresponding gear three.
[0008] Preferably, the transmission feeding assembly includes: two upright plates and a transmission belt. The two upright plates are fixedly installed on the top of the support base. Two transmission wheels are rotatably installed between the two upright plates. A motor is fixedly installed on one of the upright plates.

The detection box has moving holes that match the two upright plates and the transmission belt.
[0009] Preferably, a water tank is fixedly installed at the top of the detection box, and an installation recess is provided on the water tank.

The photosensitive element and the energized element approach the optical module, respectively detecting the optical performance and electrical performance under energized conditions, and transmitting the data to an external device for analysis. After testing, the electric push rod raises the movable plate, and the second motor rotates in the opposite direction, causing the pressure pad to release the optical module. The optical module is then conveyed out of the testing chamber by a conveyor belt. The above steps can be repeated to achieve continuous testing of the optical module.
[0014] This utility model has a reasonable structural design. Through the cooperation of the transmission feeding component, the moving frame and the second motor, it realizes the automatic feeding, detection and unloading of optical modules, which greatly improves the detection efficiency, reduces manual intervention, and improves the accuracy and stability of detection.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4 A continuously detectable optical module testing device includes: a support base 1, a test chamber 2 fixedly mounted on the support base 1, two movable frames 15 slidably mounted inside the test chamber 2, sliding plates 7 fixedly mounted on both sides of the two movable frames 15, two limiting frames 19 fixedly mounted on the side of the two movable frames 15 that are close to each other, a support spring 20 fixedly mounted inside the limiting frame 19, a sliding rod 18 fixedly mounted on one side of the support spring 20, the sliding rod 18 slidably mounted inside the limiting frame 19, a single compression pad 21 fixedly mounted on the same side of two adjacent sliding rods 18, a second motor 8 fixedly mounted on one side of the support base 1, a threaded rod 22 fixedly mounted on the output end of the second motor 8, threaded blocks 17 fixedly mounted on the bottom end of the movable frames 15, two threaded blocks 17 threadedly connected to the threaded rod 22, two threaded grooves with opposite directions of rotation on the threaded rod 22, a rotation adjustment component provided inside the test chamber 2, and a transmission feeding component provided at the top of the support base 1.
[0022] In this embodiment, the rotation adjustment component includes a three-way connecting pipe 10 and a motor 25. The three-way connecting pipe 10 is fixedly installed on one side of the detection box 2. Two limiting rings 24 are fixedly installed on the three-way connecting pipe 10. Rotating water pipes 23 are rotatably installed inside each of the two limiting rings 24. The motor 25 is fixedly installed inside the detection box 2. A gear 26 is fixedly installed at the output end of the motor 25. Two gears 27 and two gears 31 are rotatably installed inside the detection box 2. The two gears 27 mesh with the two sides of the gear 26 respectively. A rotating disk 28 is fixedly installed on one side of the gear 27. A connecting rod 29 is rotatably installed on one side of the rotating disk 28. A rack 30 is rotatably installed on one side of the connecting rod 29. The two racks 30 mesh with the corresponding gears 31 respectively. During the detection process, the humidity and temperature of the detection environment of the optical module are adjusted.
[0023] In this embodiment, the transmission feeding assembly includes two upright plates 4 and a transmission belt 5. Both upright plates 4 are fixedly installed on the top of the support base 1. Two transmission wheels 16 are rotatably installed between the two upright plates 4. A motor 6 is fixedly installed on one of the upright plates 4. The output end of the motor 6 is fixed to one of the transmission wheels 16. The outer sides of the two transmission wheels 16 are connected to the same transmission wheel 16. The detection box 2 has moving holes that match the two upright plates 4 and the transmission belt 5, realizing the automatic feeding, detection and unloading of the optical module, which greatly improves the detection efficiency.
[0024] In this embodiment, a water tank 3 is fixedly installed at the top of the detection box 2. The water tank 3 has an installation recess, and a three-way connecting pipe 10 is fixedly installed in the installation recess. An injection hole is opened at the top of the water tank 3, and a water injection pipe 9 is fixedly installed in the injection hole. An electric push rod 11 is fixedly installed inside the detection box 2. A moving plate 12 is fixedly installed at the output end of the electric push rod 11. Multiple photosensitive elements 13 and multiple power-conducting elements 14 are fixedly installed at the bottom of the moving plate 12. This allows for simultaneous detection of the optical and electrical performance of the optical module, improving the practicality of the detection device.
[0025] In this embodiment, the support base 1 has a sliding groove that matches the threaded block 17, and the detection box 2 has a sliding recess that matches the movable frame 15 and the sliding plate 7. The movable frame 15 and the sliding plate 7 are slidably installed in the sliding groove for better movement. The detection box 2 has a sliding groove that matches the rack 30, and the rack 30 is slidably installed in the sliding groove. The detection box 2 also has a moving groove that matches the connecting rod 29 for convenient control.
[0026] In this embodiment, during use, the water supply pipe 9 is connected to an external water source to ensure that the water tank 3 has sufficient water for subsequent humidity control. The transmission feeding assembly is started, and motor 6 is turned on. The output of motor 6 drives one of the transmission wheels 16 to rotate. Since the two transmission wheels 16 are connected by the transmission belt 5, the other transmission wheel 16 rotates synchronously, causing the transmission belt 5 to start running. The optical modules to be tested are placed on the transmission belt 5 in sequence. As the transmission belt 5 rotates, the optical modules enter the detection chamber 2. When the optical modules enter the detection chamber 2... After reaching the appropriate position, start motor 8. The output of motor 8 drives the threaded rod 22 to rotate. Since the threaded rod 22 has two threaded grooves with opposite directions of rotation, and the threaded blocks 17 at the bottom of the two moving frames 15 are respectively threaded onto the threaded rod 22, when the threaded rod 22 rotates, the two threaded blocks 17 will move closer or further away from each other along the threaded rod 22. As the two moving frames 15 move closer to each other, the two compression pads 21 will gradually move closer to the optical module. The sliding rod 18 slides within the limiting frame 19, and the support spring 20 is compressed. The elastic force of the support spring 20 is used to... The compression pad 21 can stably clamp the optical module, ensuring that the optical module is fixed in position and does not wobble during the testing process. Subsequently, the humidity and temperature of the testing environment for the optical module are adjusted during the testing process. The motor 3 25 is started, driving gear 1 26 to rotate. Since two gears 27 are respectively meshed on both sides of gear 1 26, the rotation of gear 1 26 will drive the two gears 27 to rotate synchronously. When gears 27 rotate, they drive the rotating disk 28 to rotate. The rotating disk 28 drives the connecting rod 1 29 to move. The connecting rod 1 29 drives the rack 30 to slide in the sliding groove. 30 meshes with gear 31. The sliding of rack 30 will drive gear 31 to rotate. Gear 31 is connected to rotating water pipe 23, thereby realizing the adjustment of the angle of rotating water pipe 23, so as to better adjust the humidity and temperature. When the electric push rod 11 is activated, the output end of the electric push rod 11 drives the moving plate 12 to move downward. Multiple photosensitive elements 13 and multiple energized elements 14 fixedly installed at the bottom of the moving plate 12 move downward and approach the fixed optical module. The photosensitive elements 13 are used to detect the optical performance of the optical module, such as optical power, optical wavelength and other parameters.The energizing element 14 provides power to the optical module and detects its electrical performance, such as current and voltage, under energized conditions. The optical module undergoes comprehensive testing via the photosensitive element 13 and the energizing element 14, and the detected data is transmitted to an external data processing device for analysis. Upon completion of the test, the output of the electric push rod 11 moves the moving plate 12 upwards, distancing the photosensitive element 13 and the energizing element 14 away from the optical module. The second motor 8 is then activated, causing its output to rotate in the opposite direction, which in turn rotates the threaded rod 22 in the opposite direction. This causes the two threaded blocks 17 to move away from each other, and consequently, the two moving frames 15 to move away from each other. The pressure pad 21 releases the optical module. As the transmission belt 5 continues to operate, the tested optical module is conveyed through the moving hole on the testing chamber 2 and exited, completing one optical module testing cycle. Afterwards, a new optical module can be placed for testing, and the above steps can be repeated to achieve continuous testing of the optical modules.
[0027] The above provides a detailed description of the continuously detectable optical module testing device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
