Description

Technical Field

[0001] This utility model relates to the field of optical fiber testing platform technology, specifically to an optical fiber axial testing platform. Background Technology

[0002] During the optical fiber drawing process, defects in the quartz raw material can cause air bubbles to form inside the fiber, manifesting as a long bubble, also known as a "black line." This interferes with the fiber splicing process and weakens its mechanical strength. On one hand, this affects the efficiency of optical fiber preform drawing and leads to more production waste; on the other hand, it also poses significant processing challenges to subsequent fiber screening and testing procedures, inevitably increasing additional costs.

[0003] Authorized publication number CN205356346U discloses an optical fiber end-face detector, including a pen body and a pen cap. The pen body has an end cap on its right end, and a lanyard loop on the right end face of the end cap, with a lanyard loop connected to a lanyard. The pen body has a rubber anti-slip layer in the middle, and a connecting ring A on the lower left side of the pen body, connected to a connecting chain. The left end of the pen body has an annular groove, and an annular boss A is located on the left side of the annular groove. A button is located on the left side of the annular boss A, and an LED indicator is located on the left side of the button. A laser connector is located on the left end face of the pen body. The lower right side of the pen cap has a connecting ring B. A dustproof sealing cap adapted to the laser connector is located in the middle of the left side wall inside the pen cap, and an annular boss B adapted to the annular groove is located on the right side inside the pen cap. In use, the dustproof sealing cap is removed, and the laser connector is aligned with the end face of the optical fiber for detection.

[0004] However, current fiber optic testing technologies largely rely on manual operation, which makes the testing process cumbersome and time-consuming. Although existing fiber optic testing platforms can achieve automation to a certain extent, they are usually not convenient for continuous machine testing of fibers, especially when running for a long time and processing multiple batches of testing tasks, which leads to a decrease in fiber optic testing efficiency.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To address the technical problems of cumbersome and time-consuming fiber optic testing processes, the inconvenience of continuous machine testing, and the low testing efficiency, this invention provides a fiber optic axial testing platform that can continuously test fibers, thereby improving testing efficiency and data accuracy. This design effectively overcomes the drawbacks of the complexity and time-consuming nature of manual testing and solves the problem that existing fiber optic testing platforms cannot conveniently perform continuous testing.

[0030] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of an optical fiber axial testing platform according to an embodiment of the present invention. The optical fiber axial testing platform includes: a positioning platform 1, a detection module 2, two winding structures 3, and a driving structure 4. The positioning platform 1 has two positioning ends arranged side by side, forming an optical fiber guiding area between the two positioning ends for the passage and support of the optical fiber 9. The detection end of the detection module 2 corresponds to the optical fiber guiding area and is used to detect internal defects of the optical fiber 9. The two winding structures 3 are respectively arranged at both ends of the optical fiber guiding area and are used to wind and release the optical fiber 9, respectively. The driving structure 4 is connected to the two winding structures 3 and is used to provide power to drive the winding structures 3 to rotate, thereby driving the optical fiber 9 to move within the optical fiber guiding area.

[0031] In this device, the two positioning ends of the positioning platform 1 form an optical fiber guiding area, through which the optical fiber 9 is inserted and supported, allowing the optical fiber 9 to move in a specific area. The detection end of the detection module 2 corresponds to the optical fiber guiding area, and the detection module 2 can detect internal defects of the optical fiber 9 when the optical fiber 9 moves. The two winding structures 3 are set at both ends of the optical fiber guiding area, respectively, for winding and releasing the optical fiber 9. They work in conjunction with the drive structure 4 to drive the winding structure 3 to rotate, thereby controlling the release and winding speed of the optical fiber 9 and ensuring that the optical fiber 9 can be detected continuously for a long time.

[0032] Please see Figure 1 To achieve integrated installation of the various components, in this embodiment, the fiber optic axial testing platform further includes a test bench 7 and a fixed frame 8. The detection module 2 and the positioning platform 1 are both mounted on the top side of the test bench 7, while one of the winding structures 3 is located on the opposite side of the top of the positioning platform 1. The fixed frame 8 is disposed on the side of the test bench 7, and the other winding structure 3 is mounted on the fixed frame 8.

[0033] To ensure that the optical fiber 9 remains stably within the fiber guiding area during movement, in this embodiment, the positioning end of the positioning platform 1 includes a positioning cylinder 12, and the positioning platform 1 also includes a detection plate 11. Two positioning cylinders 12 are respectively installed on the top sides of the detection plate 11 and arranged side-by-side. Each positioning cylinder 12 has a hole inside to allow the optical fiber 9 to pass through. These two holes together constitute the fiber guiding area, used to guide the movement path of the optical fiber 9 on the detection plate 11. In practical applications, one end of the optical fiber 9 will start from a winding structure 3, pass through the two positioning cylinders 12 sequentially, and finally connect to the other winding structure 3. When the driving device is activated and the winding structure 3 is rotated, the optical fiber 9 will be guided to the winding structure 3, and during its movement, it will sequentially pass through the fiber guiding area, thereby achieving a continuous detection process.

[0034] Preferably, in this embodiment, the detection module 2 includes a microscope 21 and a camera 22, the imaging ends of the microscope 21 and the camera 22 are both corresponding to the optical fiber guiding area; the optical fiber axial test platform also includes a controller 6 and an image display 5, the controller 6 is electrically connected to the detection module 2 and the drive structure 4, and the image display 5 is connected to the detection module 2 to display the detection results and status information.

[0035] Furthermore, the camera 22 is a high-speed camera, preferably an industrial CCD camera. This solution uses a microscope 21 and a high-speed camera. The high-resolution microscope 21 can capture high-resolution images of the optical fiber 9 and analyze the physical properties of the optical fiber 9, such as surface defects, diameter changes, and coating quality. The high-frame-rate high-speed camera can record the dynamic behavior of the optical fiber 9 under different conditions and analyze the dynamic characteristics of the optical fiber 9, such as bending angle and vibration frequency.

[0036] During implementation, a microscope 21 and a high-speed camera are configured. The drive structure 4 and the winding structure 3 guide the optical fiber 9 through the field of view of the microscope 21. Continuous imaging by the high-speed camera, combined with artificial intelligence image recognition technology, displays the recognition results in real time on the image display 5, thereby automatically detecting the axial direction of the optical fiber 9 and accurately locating the position of the black line on the optical fiber 9. This method effectively overcomes the complexity, time-consuming nature, and susceptibility to omissions associated with manual inspection, solving the problem that existing optical fiber 9 inspection platforms struggle to continuously perform machine inspections.

[0037] Please see Figures 1 to 4 In this embodiment, both winding structures include a rotating drum 31, which is disposed on the side of the positioning platform 1. One end of the rotating drum 31 has a limiting component 32 with a cross-sectional area larger than the rotating drum 31 itself, which is used to limit the rotation on the side of the rotating drum 31. The other end of the rotating drum 31 is connected to the driving structure 4. The two rotating drums 31 are an unwinding drum and a winding drum, respectively. The unwinding drum is responsible for releasing the optical fiber 9, while the winding drum is used to collect the tested optical fiber 9. The two rotating drums 31 work together to ensure the orderly flow of the optical fiber 9 in the optical fiber guiding area. The unwinding drum releases the optical fiber 9 at a stable rotation speed, providing a continuous and stable supply of optical fiber 9 for subsequent testing. The winding drum neatly winds up the tested optical fiber 9, ensuring the quality of the optical fiber 9 and facilitating subsequent storage and transportation.

[0038] Please see Figures 2 to 4The limiting component 32 can be detached from one side of the rotating drum 31 to install and unload the wound optical fiber 9. In one embodiment, the limiting component 32 includes a connecting plate 321, a limiting slide plate 322, and a plurality of positioning plates 323. The connecting plate 321 is movably covered with a limiting slide plate 322 on the side near the rotating drum 31. A mounting groove is provided in the middle of the limiting slide plate. The plurality of positioning plates 323 are sequentially distributed on the inner circumference of the mounting groove. One end of each positioning plate 323 is fixedly connected to the groove wall of the mounting groove, and the other end is fixed to the limiting slide plate 323. The center of the sliding plate 322 extends; one end of the rotating drum 31 is provided with a positioning shaft 311, which is coaxially arranged with the rotating drum 31. Multiple positioning grooves 312 are sequentially provided on the outer side of the positioning shaft 311 along its circumferential direction. Each of the positioning grooves 312 corresponds to a number of positioning plates 323 and extends along the axial direction of the positioning shaft 311. The connecting plate 321 is connected to the positioning grooves 312 of the positioning shaft 311 through the limiting sliding plate 322 and the positioning plates 323, thereby realizing the connection with the positioning shaft 311 and the rotating drum 31.

[0039] Preferably, four positioning plates 323 and four positioning grooves 312 are provided, and the four positioning plates 323 and four positioning grooves 312 are evenly distributed around the circumference of the positioning shaft 311. A rotating shaft 326 is also provided on the side of the connecting plate 321 away from the limiting slide plate 322, so as to be rotatably connected to the fixed frame 8 through the rotating shaft 326.

[0040] Furthermore, in some embodiments, a limiting slider 324 is fixedly provided on the side of the limiting slide plate 322 near the connecting plate 321, and a limiting groove 325 matching the limiting slider 324 is provided on the corresponding side of the connecting plate 321. When the limiting slide plate 322 is fitted and installed on one side of the connecting plate 321, the limiting slider 324 can be inserted into the limiting groove 325 to ensure that the limiting slide plate 322 can cover one side of the connecting plate 321. When the two are combined, a disc-shaped structure is formed.

[0041] During implementation, after the fiber optic roller inspection is completed, the positioning plate 323 can be moved outward by sliding the limiting slide plate 322 outward, thereby disengaging from the positioning groove 312 and releasing the restriction of the positioning groove 312 on the positioning plate 323 and the connecting plate 321. At this time, the operator can easily remove the rotating drum 31 from the side of the connecting plate 321 to replace the fiber optic roller for further inspection. The entire operation process is simple and convenient.

[0042] The above embodiments are merely various possible implementations of the embodiments of this application, and the embodiments of this application are not limited thereto.

[0043] Please see Figure 1Preferably, in this embodiment, the drive structure 4 includes a servo motor 41, and the drive end of the servo motor 41 is connected to the two winding structures.

[0044] In one embodiment, two servo motors 41 are provided, each connected to one end of one of the two winding structures, and the two servo motors 41 are connected to the controller 6. Throughout the process, the seamless cooperation of the two rotating drums 31 not only improves the production efficiency of the optical fiber 9, but also greatly reduces losses and error rates during production.

[0045] It should be noted that in this solution, the servo motor 41 maintains a constant rotation speed. Combined with the fixed shooting frequency of the high-speed camera, this allows for accurate calculation and location of the specific position of the black line within the entire optical fiber reel 9. The filenames of the captured images are named according to the shooting time. Furthermore, through artificial intelligence training, the system can distinguish between axial images with and without black lines. After identifying images with black lines, the filenames of these images are listed in an Excel spreadsheet.

[0046] Of course, in other possible embodiments, the servo motor 41 can also be provided, and the drive end of the servo motor 41 can be connected to two rotating drums 31 by setting a transmission belt assembly or a transmission gear assembly, so as to drive the two rotating drums 31 to rotate synchronously in the same direction, so as to synchronously control the winding and unwinding speed of the optical fiber 9.

[0047] Working principle: During use, slide the limiting slide plate 322 outward, causing the positioning plate 323 to move out of the positioning groove 312. At this time, the rotating drum 31 can be removed. After installing the fiber roller on the rotating drum 31, pass the fiber 9 through the holes of the two positioning drums 12 and connect it to the other rotating drum 31. During detection, the rotating drum 31 is driven by the servo motor 41 to control the release and winding of the fiber 9, causing the fiber 9 to pass through the fiber guide area in sequence. The fiber 9 is photographed by the microscope 21 and the high-speed camera. Combined with artificial intelligence image recognition technology, the recognition results are displayed on the image display 5 in real time, thereby automatically realizing the axial detection of the fiber 9. After the detection of one fiber roller is completed, slide the limiting slide plate 322 outward, causing the positioning plate 323 to move outward and thus disengage from the positioning groove 312. After the positioning groove 312 releases the restriction of the positioning plate 323 and the connecting plate 321, remove the rotating drum 31 and then remove the fiber 9 that has been detected.

[0048] This invention comprises a positioning platform 1, a detection module 2, two winding structures 3, and a driving structure 4. The positioning ends of the positioning platform 1 form a fiber optic guiding area, facilitating the insertion and support of the fiber optic cable 9, ensuring its free movement within a designated area. The detection end of the detection module 2 corresponds to the fiber optic guiding area, enabling real-time monitoring of internal defects in the fiber optic cable 9 during its movement. The dual winding structures 3, located on either side of the fiber optic guiding area, are responsible for winding and releasing the fiber optic cable 9 respectively. Combined with the rotational control of the driving mechanism, the two winding structures 3 precisely adjust the release and winding speeds of the fiber optic cable 9, ensuring continuous detection and improving detection efficiency and data accuracy. This design effectively overcomes the complexity and time-consuming nature of manual inspection, solving the problem of existing fiber optic cable 9 inspection platforms being unable to conveniently perform continuous inspections.
