Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical communication measurement technology, and in particular to an automatic optical communication measurement device. Background Technology
[0002] With the rapid development of 5G optical communication, the demand for optical devices in optical communication is also increasing. As labor costs rise and the industry transforms, more and more factories in China will be able to independently produce optical transceivers (TOs). Traditional low-speed device types have mature processes, but with the increasing diversity of optical communication needs, the diversity of laser packaging types is also creating more demands. In particular, as optical communication speeds continue to increase, it is necessary not only to measure the current-voltage-power characteristics of devices, but also to measure their spectral characteristics.
[0003] Current automatic measurement devices for optical communication have been found to have at least the following technical problems:
[0004] First, traditional devices suffer from significant technical bottlenecks in multi-channel collaborative measurement. Their hardware architecture and control logic are ill-suited for large-scale testing scenarios. Specifically, the number of measurement channels is limited, typically supporting only manual switching of a single channel or eight channels. When faced with the requirement of parallel testing of optical communication measurement boards that need to connect to sixty-four lasers, manual intervention is required, involving manually plugging and unplugging devices and manually adjusting the measurement lens to align with different channels. Completing full-channel testing can take several hours, and the cost of manual intervention increases linearly with the number of channels. At the same time, due to differences in the force and angle of operation during manual switching, the coupling distance between the lens and the laser is easily deviated, resulting in inconsistent measurement benchmarks for each channel and making it difficult to guarantee the consistency and reliability of measurement results. Furthermore, traditional devices lack multi-channel linkage control algorithms and cannot automatically schedule the measurement sequence according to a preset program. When dealing with mixed testing of multiple types of devices, frequent replacement of jumper modules is required, further increasing operational complexity and the risk of misjudgment. This has become a key technical bottleneck restricting the improvement of mass production efficiency of optical communication devices.
[0005] Secondly, traditional optical communication measurement devices have significant shortcomings when dealing with diverse laser types. The manual insertion and removal of components and replacement of jumpers to adapt to different types of lasers is not only time-consuming and labor-intensive when there are more than 20 types of components, but it is also prone to hardware failure due to incorrect jumper connections or improper insertion and removal, resulting in measurement data deviations or even equipment damage. In addition, traditional devices rely on manual adjustment for coupling alignment, resulting in slow spectral measurement speed. The coupling measurement of a single component generally takes more than 8 seconds, which is difficult to meet the rapid testing requirements of mass production. At the same time, the lack of a reliable automatic limit protection mechanism makes the motor prone to mechanical failure due to exceeding the reasonable space range, affecting the stability of the measurement. Utility Model Content
[0006] Technical problems to be solved
[0007] To address the shortcomings of existing technologies, this utility model provides an automatic optical communication measurement device. It solves the significant deficiencies of traditional optical communication measurement devices when testing diverse laser types. The manual insertion and removal of components and replacement of jumpers to adapt to different laser types is not only time-consuming and labor-intensive when dealing with more than 20 different component types, but also prone to hardware failures due to incorrect jumper connections or improper insertion / removal, leading to measurement data deviations or even equipment damage. Furthermore, traditional devices rely on manual adjustment for coupling alignment, resulting in slow spectral measurement speeds; single-component coupling measurements typically take over 8 seconds, making it difficult to meet the rapid testing requirements of mass production. Additionally, the lack of a reliable automatic limit protection mechanism makes the motor susceptible to mechanical failure due to exceeding reasonable space limits, affecting measurement stability.
[0008] Technical solution
[0009] To achieve the above objectives, this utility model provides the following technical solution:
[0010] The system includes a vibration-proof platform, on which is mounted an optical communication measurement board. Above the optical communication measurement board is a visual monitoring device with a built-in visual sensor. Above the optical communication measurement board is a measurement mechanism for automatically switching pins to adapt to the testing requirements of various laser types, eliminating the need for manual component insertion and removal. It is also centrally controlled via a serial port connection to a computer. Above the vibration-proof platform is an automatic shifting mechanism for automatically adjusting the position of the optical communication measurement lens to ensure accurate alignment with the laser to be measured and to prevent the motor from exceeding the reasonable space range and causing malfunctions.
[0011] Preferably, the automatic shifting mechanism includes a first sliding guide rail with a groove, a first sliding plate within the groove, a first servo motor, a second limiting plate with a built-in touch switch, a second sliding guide rail on the first sliding plate, a second servo motor on the second sliding guide rail, a second sliding plate within the groove, a first limiting plate with a built-in touch switch, a first cable drag chain on the second servo motor, a second cable drag chain on the second sliding plate, a third sliding guide rail with a groove, a third sliding plate within the groove, and a third servo motor on the third sliding guide rail. The measuring mechanism includes an optical communication measuring lens fixedly mounted on a visual monitoring device. The optical communication measuring plate has sixty-four channels, and a laser measuring base plate is located below the optical communication measuring plate.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] I. An automatic shifting mechanism is incorporated, comprising components such as a first sliding guide rail, a first servo motor, a first sliding plate, a second sliding guide rail, a second servo motor, a second sliding plate, a third sliding guide rail, and a third servo motor, forming a three-dimensional moving system with X, Y, and Z-axis linkage. The first servo motor drives the first sliding plate to move longitudinally along the first sliding guide rail, achieving Y-axis position adjustment; the second servo motor drives the second sliding plate to move laterally along the second sliding guide rail, achieving X-axis position adjustment; and the third servo motor drives the third sliding plate to move vertically along the third sliding guide rail, achieving Z-axis position adjustment. The height adjustment, with the coordinated operation of the three components, allows for precise adjustment of the spatial position of the optical communication measurement lens, enabling it to quickly align with the laser at any position within the 64 channels of the optical communication measurement board, without the need for manual operation. Simultaneously, both the second limit plate on the first sliding rail and the first limit plate on the second sliding rail have built-in touch switches. When either the first or second sliding plate moves beyond its preset travel range, the touch switch immediately triggers a signal, controlling the corresponding servo motor to stop operating. This prevents mechanical collisions or component derailment due to overtravel, effectively avoiding mechanical failures and ensuring the safety and stability of the device's operation.
[0014] Second, a measurement mechanism is provided, with a visual monitoring device at its core. Its built-in high-sensitivity visual sensor can capture the position coordinates of the laser on the optical communication measurement board in real time and generate accurate three-dimensional positioning data through algorithms. The laser measurement base plate serves as an auxiliary calibration module, providing a reference plane. Together with the visual sensor, it forms a dual positioning mechanism to ensure that the optical communication measurement lens completes initial position calibration before movement. During the measurement process, the visual monitoring device transmits real-time monitoring data to the control system, dynamically guiding the X / Y / Z three-axis servo motors of the automatic shifting mechanism to work in tandem, enabling the optical communication measurement lens to quickly approach the target laser. When the lens approaches the preset range, its built-in autofocus function is activated, and the vertical height is finely adjusted through an optical feedback mechanism. Combined with the control precision of the three-axis movement, precise coupling between the lens and the laser end face is achieved. Attached Figure Description

Detailed Implementation
[0022] This application provides an automatic optical communication measurement device, which effectively solves the significant shortcomings of traditional optical communication measurement devices when dealing with diverse laser types. The manual insertion and removal of devices and replacement of jumpers to adapt to different types of lasers is not only time-consuming and labor-intensive when there are more than 20 types of devices, but also prone to hardware failure due to incorrect jumper connections or improper insertion and removal, resulting in measurement data deviations or even equipment damage. In addition, traditional devices rely on manual adjustment for coupling alignment, resulting in slow spectral measurement speed. The coupling measurement of a single device generally takes more than 8 seconds, which is difficult to meet the rapid testing requirements of mass production.

[0023] Example
[0024] like Figures 1-4 As shown, the technical solution in this application aims to effectively address the significant shortcomings of traditional optical communication measurement devices in testing diverse laser types. The manual insertion and removal of components and replacement of jumpers to adapt to different laser types is not only time-consuming and labor-intensive when dealing with more than 20 types of components, but also prone to hardware failures due to incorrect jumper connections or improper insertion / removal, resulting in measurement data deviations or even equipment damage. Furthermore, traditional devices rely on manual adjustment for coupling alignment, leading to slow spectral measurement speeds; single-component coupling measurements typically take over 8 seconds, failing to meet the rapid testing requirements of mass production. Additionally, the lack of a reliable automatic limit protection mechanism makes the motor susceptible to mechanical failure due to exceeding reasonable space limits, affecting measurement stability. The overall approach is as follows:
[0025] To address the problems existing in the prior art, this utility model provides an automatic optical communication measurement device, including a vibration-proof table 11, an optical communication measurement board 12 on the vibration-proof table 11, a 64-channel 25 on the optical communication measurement board 12 for connecting multiple lasers, an optical communication measurement lens 13 above the optical communication measurement board 12 for measuring lasers, capable of automatic focusing, and for automatically switching pins to achieve easy-to-use functions for various laser types.
[0026] An automatic shifting mechanism is provided above the vibration table 11. The automatic shifting mechanism is used to automatically adjust the position of the optical communication measurement lens 13 so that the optical communication measurement lens 13 is accurately aligned with the laser to be measured, and to prevent the motor from exceeding the reasonable space range and causing failure. A measurement mechanism is provided above the optical communication measurement board 12. The measurement mechanism is used to automatically switch pins to adapt to the testing requirements of various laser types without the need for manual plugging and unplugging of components, and to achieve centralized control by connecting to a computer via a serial port.
[0027] The automatic shifting mechanism includes a first sliding guide rail 14 with a groove. A first sliding plate 16 is disposed within the groove. A first servo motor 15 is mounted on the first sliding guide rail 14 to control the sliding position of the first sliding plate 16 on the first sliding guide rail 14. A second limiting plate 32 is mounted on the first sliding guide rail 14 and has a built-in touch switch. The second limiting plate 32 is used to prevent the first sliding plate 16 from disengaging from the first sliding guide rail 14, thereby preventing malfunction. When the sliding plate 16 slides away from the expected track and triggers the touch switch built into the second limit plate 32, the first servo motor 15 will immediately stop running to prevent malfunction. The first sliding plate 16 is provided with a second sliding guide rail 17. When the first sliding plate 16 slides on the first sliding guide rail 14, it synchronously drives the second sliding guide rail 17 to move. The second sliding guide rail 17 has a groove, and a second servo motor 19 is provided on the second sliding guide rail 17. A second sliding plate 21 is located within the groove on the second sliding guide rail 17. The second servo motor 19 is used to control the second sliding plate 21. 1. The second sliding plate 21 slides within the groove of the second sliding guide rail 17. The second sliding guide rail 17 is equipped with a first limiting plate 31, which has a built-in touch switch. The first limiting plate 31 is used to prevent the second sliding plate 21 from disengaging from the second sliding guide rail 17 and causing a malfunction. When the second sliding plate 21 slides off the expected trajectory and triggers the built-in touch switch of the first limiting plate 31, the second servo motor 19 will immediately stop operating to prevent a malfunction. The second servo motor 19 is equipped with a first cable drag chain 18, which is used to protect the first servo motor 19. To prevent the external wires on motor 15 from being bent, a second cable drag chain 23 is provided on the second sliding plate 21. The second cable drag chain 23 is used to protect the external wires on the second servo motor 19 from being bent. A third sliding guide rail 28 is provided on the second sliding plate 21. A groove is opened on the third sliding guide rail 28. A third sliding plate 29 is provided in the groove of the third sliding guide rail 28. A third servo motor 27 is provided on the third sliding guide rail 28. The third servo motor 27 is used to control the sliding position of the third sliding plate 29 in the groove of the third sliding guide rail 28.
[0028] The measuring mechanism includes a visual monitoring device 33, with an optical communication measuring lens 13 fixedly mounted on it. The visual monitoring device 33 has a built-in visual sensor. A laser measuring base plate 22 is located below the optical communication measuring board 12, used for initial laser calibration. When the built-in visual sensor of the visual monitoring device 33 is activated, the device controls the second servo motor 19, the first servo motor 15, and the third servo motor 27 via signal transmission. The second servo motor 19 drives the second sliding plate 21 to open on the second sliding guide rail 17. The optical communication measurement lens 13 moves along the X-axis by moving within the groove of the sliding rail 14. The first servo motor 15 drives the first sliding plate 16 to move within the groove of the sliding rail 14, thus moving the optical communication measurement lens 13 along the Y-axis. The third servo motor 27 drives the third sliding plate 29 to slide within the groove of the sliding rail 28, thus moving the optical communication measurement plate 12 along the Z-axis. This aligns the optical communication measurement lens 13 on the third sliding plate 29 with the laser to be measured and maintains the set height, achieving automatic coupling and measurement.
[0029] Working principle:
[0030] In the first step, the operator connects the laser to be measured to the 64-channel 25 of the optical communication measurement board 12. This channel can simultaneously connect multiple lasers to meet batch measurement needs. After the device is started, the vision sensor built into the vision monitoring device 33 scans the channel status in real time. When a device connection signal is detected, a command is sent to the control system via serial port to trigger the automatic shifting mechanism to start running. The second servo motor 19 drives the second sliding plate 21 to move laterally within the groove of the second sliding guide rail 17, realizing the horizontal (X-axis) position adjustment of the optical communication measurement lens 13. The first servo motor 15 synchronously drives the first sliding plate 16 to move longitudinally within the groove of the first sliding guide rail 14, completing the coordinate calibration of the lens in another horizontal dimension (Y-axis). The third servo motor 27 drives the third sliding plate 29 to move vertically within the groove of the third sliding guide rail 28, precisely adjusting the vertical distance (Z-axis) between the lens and the laser. The three components, through the coordinated calculation of the control system, form a three-dimensional linkage control, enabling the optical communication measurement lens 13 to move quickly and accurately to the desired position. Directly above the target laser, initial alignment is completed. During this process, the device's safety protection mechanism is activated simultaneously: the second limiting plate 32 on the first sliding guide rail 14 and the first limiting plate 31 on the second sliding guide rail 17 both have built-in touch switches. If the first sliding plate 16 or the second sliding plate 21 exceeds the preset travel range due to program errors or mechanical failures, the touch switch will immediately send a stop signal, and the corresponding first servo motor 15 or second servo motor 19 will stop running instantly to avoid mechanical collisions or cable breakage caused by components leaving the track, ensuring the safety and stability of the device's operation. During the entire shifting process, the first cable drag chain 18 and the second cable drag chain 23 respectively protect the power and signal lines connected to the servo motors. The flexible drag chain structure guides the cables to move synchronously with the sliding plates, preventing the cables from breaking or making poor contact due to frequent bending, further improving the reliability of the device. When the vision sensor confirms through the reference data of the laser measurement base plate 22 that the spatial position error between the lens and the laser is less than the set threshold, the automatic shifting mechanism stops operating.
[0031] In the second step, after the vision sensor confirms through the calibration signal of the laser measurement base plate 22 that the horizontal position and vertical height of the optical communication measurement lens 13 and the laser have reached the set threshold, the lens activates the built-in autofocus function. It accurately locks the laser measurement target point through the optical system. Relying on the stable support of the vibration-proof table 11, it ensures that the coupling distance error between the lens and the laser end face is controlled within the micrometer range, and completes the precise alignment of the physical connection. At this time, the lens's built-in measurement module automatically collects the laser's optical power, wavelength, spectrum and other parameters, and transmits them to the computer for processing and storage in real time through the serial port. After a single measurement is completed, if it is necessary to switch to other channel lasers, the control system automatically triggers the automatic shifting mechanism to reset. Based on the three-dimensional moving system composed of the first sliding guide rail 14, the second sliding guide rail 17 and the third sliding guide rail 28, and the coordinated drive of the first servo motor 15, the second servo motor 19 and the third servo motor 27, the positioning process of the next channel is executed. No manual intervention is required throughout the process. Combined with the design of the sixty-four channels 25 of the optical communication measurement board 12, the fully automated cyclic measurement of multi-channel lasers is realized.
[0032] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
