Description

Technical Field

[0001] The present invention relates to the technical field related to the production of optical modules, and specifically to a power-on test device for the production of optical modules. Background Technique

[0002] Optical modules are key components used for data transmission in network communication devices. During their production process, power-on test operations are required. However, the existing power-on test devices for the production of optical modules still have certain defects when in use; During use, the existing power-on test devices have complex structures, which increase the overall operation difficulty and lead to an increase in the overall manufacturing and maintenance costs. The complex structures also increase the overall failure rate, affecting the stability and accuracy of the tests; In order to overcome the above defects, in the prior art one (a Chinese patent with an application number of 202122862471.1 and an application date of November 19, 2021), a test device for the production of a filter self-check module is provided. An arched detection seat is provided on the bottom plate, and a positioning groove is provided on the upper surface of the detection seat for placing the self-check module circuit board. A lifting plate is also provided above the detection seat, and a support plate is also provided on one side of the detection seat. A cylinder is provided on the support plate, and the telescopic end of the cylinder is connected to the lifting plate. A plurality of detection contacts are provided on the lifting plate, and the detection contacts are electrically connected to the detection center. The detection center abuts against the power-on contacts of the self-check module circuit board for detection. The cylinder pushes the lifting plate to descend, so that the detection contacts on the lifting plate abut against the power-on contacts of the self-check module circuit board, and the self-check module circuit board is connected to the detection center to conduct a power-on test on the self-check module circuit board, ensuring the qualified detection of the self-check module circuit board, with high detection efficiency, good detection effect, simple structure, and low manufacturing cost; There is also prior art two (a Chinese patent with an application number of 202120998339.0 and an application date of May 11, 2021), a main test box for an optical module test device, including a bottom plate. A main test box is fixedly connected to the top of the bottom plate. Two test components for detecting the module to be tested are arranged inside the main test box. Foot pads are fixedly connected to the four corners of the bottom of the bottom plate. The split design of the MCU control board, the BERT test main board, and the power board can quickly find the cause of the problem. When a failure occurs, only some circuit boards need to be replaced, which can not only save time but also reduce production costs, and can be changed into two workstations to improve work efficiency and is convenient to use; And Prior Art Three (a Chinese patent with application number 202122736471.7 and application date November 9, 2021) is a high-temperature aging test device for optical module production, including a machine body. A test chamber is provided inside the machine body. Heating plates are fixedly installed on the inner wall and bottom of the test chamber, and heating wires are fixed on the surface of the heating plates. Through the setting of the uniform mechanism, the hot air above the test chamber can be blown to the lower part of the test chamber by the rotation of the fan blades, and the speed reducer can reduce the rotation speed of the fan blades, so that the fan blades can play a role in uniform stirring, preventing the hot air from accumulating above the test chamber and causing uneven temperature. And through the setting of the rapid cooling mechanism, the air outside can be sent into the test chamber while extracting the hot air inside the test chamber, so that the optical module inside the test chamber can be quickly cooled without waiting for the optical module to cool naturally, improving the high-temperature aging test efficiency of the optical module.

[0003] Although the prior art can simplify the overall detection structure, during the working process, when placing the optical module to be detected on the detection seat for detection, it is necessary to manually align the power-on contacts and repeatedly adjust the position of the optical module, resulting in a long limit operation time, thus reducing the operation efficiency. And the contact points are prone to shift during movement, resulting in unstable power-on test connection, reducing the rigor of the test results, and affecting the accuracy of the test results.

[0004] In view of the above problems, it is urgent to innovate and design on the basis of the original power-on test device for optical module production. Therefore, we have proposed a power-on test device for optical module production that can well solve the above problems. Summary of the Invention

The bottom of the rotating piece is connected by a second spring to a second pressing plate. The optical module is limited by the cooperation of the first pressing plate and the second pressing plate, which not only effectively avoids the displacement of the optical module during the test process, but also makes the whole operation process smooth and natural, greatly reducing the difficulty of installing and detecting the optical module and reducing the complexity of manual operation.

The baffle is rotatably connected through a rotating shaft inside a second arc groove. The second arc groove is opened at the side end of the test box. A torsion spring is installed outside the rotating shaft. The baffle rotates inside the second arc groove through the rotating shaft, enabling the gas sprayed by the nozzle to quickly clean the contact block on the test seat and the contact block under the optical module, reducing the problem of poor contact caused by the accumulation of dirt on the surface of the contact block, and ensuring the stability and accuracy of the test signal transmission.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1:

[0019] In this embodiment, in order to improve the rigor of the optical module test, the optical module is restricted inside the test box 3 through the cooperation of the first pressing plate 6 and the second pressing plate 14, aiming to reduce the problem that the displacement of the optical module during the test leads to a decrease in the rigor of the test data, as Figures 1-8The described technical solution includes a test box 1 provided. Inside the test box 1, a moving seat 2 is provided. A test box 3 is installed on the moving seat 2. Inside the test box 3, a test seat 4 is installed. Inside the test box 3, a first pressing plate 6 is connected by a first spring 5. A clamping component is installed at the side end of the first pressing plate 6. The clamping component includes a lifting rod 7 installed at the side end of the first pressing plate 6. The lifting rod 7 is connected through a through groove 8. The through groove 8 is opened at the side end of the test box 3. A sliding column 9 is installed at the end of the lifting rod 7. The sliding column 9 is slidably connected inside a first arc-shaped groove 10. The first arc-shaped groove 10 is opened at the side end of a rotating column 11. A rotating piece 12 is provided on the rotating column 11. The bottom of the rotating piece 12 is connected to a second pressing plate 14 by a second spring 13. The optical module is limited by the cooperation of the first pressing plate 6 and the second pressing plate 14. Multiple groups of moving seats 2 and test boxes 3 are provided inside the test box 1. The test box 3 is moved out through the moving seat 2, which not only facilitates comparative experiments and increases the overall detection efficiency, but also makes it convenient to place the optical module to be detected on the test seat 4 inside the test box 3. At this time, the contact blocks of the optical module are in precise contact with the contact blocks on the test seat 4, enabling the test box 1 to smoothly carry out test operations. When the optical module is placed on the test seat 4, the optical module presses the first pressing plate 6 at the bottom, causing the first spring 5 under the first pressing plate 6 to contract. And the lifting rod 7 at the side end of the first pressing plate 6 moves inside the through groove 8 at the side end of the test box 3, causing the sliding column 9 at the end of the lifting rod 7 to move downward. Since the sliding column 9 is slidably connected inside the first arc-shaped groove 10 of the rotating column 11, it is convenient for the rotating column 11 to rotate. The rotating column 11 drives the rotating piece 12 to rotate, so that the upper surface of the optical module is limited by the cooperation of the second spring 13 and the second pressing plate 14 under the rotating piece 12. Since the bottom of the second pressing plate 14 is arc-shaped, the problem of the second pressing plate 14 affecting the optical module during rotation is reduced. The optical module is restricted inside the test box 3 by the cooperation of the first pressing plate 6 and the second pressing plate 14, facilitating detection operations. It not only effectively avoids the displacement of the optical module during the test, ensuring the accuracy and stability of the test, but also the entire operation process is smooth and natural, greatly reducing the difficulty of installing and detecting the optical module, reducing the tediousness of manual operations, and significantly improving the quality and efficiency of the detection work. Embodiment 2:

[0020] In this embodiment, in order to improve the stability of test signal transmission, it is used through a temperature control component provided. Its purpose is to reduce the problem of poor contact caused by the accumulation of dirt on the surface of the contact block. Specifically, as Figures 1-4As shown in the figure, an auxiliary component is installed inside the test box 3. The auxiliary component includes a third spring 15 installed inside the test box 3. An inclined block 16 is installed at the end of the third spring 15. The inclined block 16 is located at the side end of the optical module. A temperature control component is arranged at the side end of the test box 1. The temperature control component includes a temperature control box 17 installed at the side end of the test box 1. A conveying member 18 is arranged inside the temperature control box 17. The output end of the conveying member 18 is connected to a conveying pipeline 19. The conveying pipeline 19 is connected through the inside of the test box 1. A nozzle 20 is installed at the end of the conveying pipeline 19. The nozzle 20 is located at the side end of the test box 3. A pressing rod 21 is installed at the side end of the inclined block 16. After the pressing rod 21 moves, it contacts the baffle 22. The baffle 22 is rotatably connected inside the second arc-shaped groove 24 through a rotating shaft 23. The second arc-shaped groove 24 is opened at the side end of the test box 3. A torsion spring 25 is installed on the outside of the rotating shaft 23. When the optical module is pressed down, its side end squeezes the inclined block 16, causing the inclined block 16 to move to both sides through the cooperation of the third spring 15. The third spring 15 rebounds to limit the side end of the optical module by the inclined block 16. It can not only effectively limit the side end of the optical module, greatly improve the stability of the optical module placement, reduce the problem that the position deviation of the optical module caused by external factors affects the accuracy of the test results, but also reduce the equipment maintenance cost. The air is heated or cooled by the temperature control box 17, and the processed air is transmitted through the cooperation of the conveying member 18 and the conveying pipeline 19 to heat and cool the temperature inside the test box 1, creating different temperature environments for the optical module test, enabling the device to meet the power-on conditions of the optical module at different temperatures, increasing the reliability of the test data, improving the adaptability of the device. Part of the gas is ejected through the nozzle 20. Since the inclined block 16 moves to both sides, the pressing rod 21 at its side end pushes the baffle 22, causing the baffle 22 to rotate inside the second arc-shaped groove 24 through the rotating shaft 23, facilitating the gas ejected by the nozzle 20 to be introduced into the test box 3 through the second arc-shaped groove 24, quickly cleaning the contact blocks on the test seat 4 and the contact blocks under the optical module, reducing the problem of poor contact caused by the accumulation of dirt on the surface of the contact blocks, ensuring the stability and accuracy of the test signal transmission, extending the service life of the test equipment, improving the overall test efficiency. The torsion spring 25 arranged on the outside of the rotating shaft 23 facilitates the rotation of the pressing rod 21 after moving, improving the reusable performance and automation degree of the equipment, and reducing the damage problem caused by manual intervention. Embodiment 3:

[0021] In this embodiment, in order to reduce the overall operation cost, it is used through the arranged driving component, and its purpose is to reduce the problem of cost increase caused by adding additional driving, specifically as Figures 1-4 and Figure 9 Figure 10As shown in the figure, a storage seat 26 is installed inside the test box 1. A disassembly part 27 is arranged at the bottom of the storage seat 26. The disassembly part 27 is adapted to a disassembly hole 28. The disassembly hole 28 is opened at the top of the rotating column 11. A driving component is installed at the side end of the storage seat 26. The driving component includes a motor 29 installed at the side end of the storage seat 26. The output end of the motor 29 is connected to a threaded rod 30. The threaded rod 30 is connected through the moving seat 2. The threaded rod 30 is arranged in parallel with the guide rod 31. The guide rod 31 is connected through the moving seat 2. The output end of the motor 29 is connected to a first fan 33 through a first driving part 32. The rotating shaft of the first fan 33 is connected to a second fan 35 through a second driving part 34. The first fan 33 and the second fan 35 are installed at the bottom of the storage seat 26. When it is necessary to take out the optical module, the disassembly part 27 installed at the bottom of the storage seat 26 is moved into the disassembly hole 28 at the top of the rotating column 11, and the rotating column 11 is driven to rotate through the disassembly part 27, so that the optical module is ejected through the cooperation of the first spring 5 and the first pressing plate 6. This not only simplifies the process of taking out the optical module, avoids complex manual disassembly operations, reduces the risk of damage to the optical module during the taking-out process, but also improves the convenience and safety of the operation. When the motor 29 is turned on, the moving seat 2 is driven to move through the cooperation of the threaded rod 30 and the guide rod 31, making the moving process accurate and stable, facilitating the test box 3 to quickly and accurately move to the appropriate position, facilitating the operation of the optical module, and improving the smoothness of the test process. Moreover, the output end of the motor 29 drives the first fan 33 to rotate through the first driving part 32, enabling the rapid and convenient adjustment of the temperature inside the test box 1, improving the accuracy and reliability of the test data. The driving shaft of the first fan 33 drives the second fan 35 to rotate through the second driving part 34. The overall structure is simple, making full use of the power of the motor 29, reducing the problem of cost increase caused by adding additional drives, enhancing the circulation and flow of the air inside the test box 1, further improving the uniformity of temperature adjustment, facilitating rapid test operations, and reducing the problem of reduced detection efficiency caused by waiting for temperature adjustment.
