Description

Technical Field

[0001] The present application relates to the field of optical fiber fusion splicing, and in particular to an optical fiber fusion splicing device and method. Background Art

[0002] In the field of optical communications, optical fiber is the core medium for information transmission, and its performance directly affects the efficiency and stability of the entire communication system. As a key link in optical fiber connection, the quality and efficiency of optical fiber splicing are crucial to ensure the continuity and reliability of the communication system. However, the existing optical fiber splicing technology still faces many challenges in practical applications.

[0003] The problem of optical fiber loss has always been one of the key factors restricting the improvement of optical fiber communication quality. The loss in the optical fiber fusion process mainly comes from the uncleanness of the optical fiber end face, inaccurate cutting angle and unreasonable setting of fusion parameters. Traditional optical fiber fusion equipment usually divides optical fiber cutting and fusion into two independent steps, which not only increases the complexity of operation, but also reduces work efficiency. In addition, due to the need to frequently replace tools and re-pick up and put back optical fibers, the optical fiber end face is easily contaminated, further exacerbating the problem of optical fiber loss.

[0004] The existing fiber fusion splicing equipment generally has a low degree of automation, is complex to operate, and requires high professional skills and experience.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0047] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0049] Existing optical fiber fusion splicing equipment is usually divided into two processes: cutting and fusion splicing. However, this requires the cut optical fiber to be taken out and moved to the fusion splicing position. Frequent taking and placing of the optical fiber not only reduces the fusion splicing efficiency, but also may cause contamination of the cut end face of the optical fiber in this process, affecting the fusion splicing effect. For this reason, the present application provides an optical fiber fusion splicing equipment that integrates the two processes of cutting and fusion splicing on one device, thereby eliminating the need for frequent taking and placing of the optical fiber, thereby preventing contamination of the cut end face of the optical fiber and further improving the fusion splicing effect.

[0050] The optical fiber fusion splicing equipment provided in the present application includes a frame 100, a cutting component 200, a pushing and limiting component 300, a fusion splice 400, an image acquisition module 500 and a lifting and positioning component 600, wherein the cutting component 200 is installed on the frame 100, and the cutting component 200 is used for cutting the optical fiber end; the pushing and limiting component 300 is installed on the frame 100, and the pushing and limiting component 300 is located on one side of the cutting position of the cutting component 200; the pushing and limiting component 300 is used for moving and positioning the optical fiber; the fusion splice 400 is fixedly installed on the frame 100, and the fusion splice 400 is used for fusion splicing the optical fiber end; the image acquisition module 500 is installed on the frame 100, and the image acquisition module 500 is used for collecting images of the cut end face of the optical fiber; the lifting and positioning component 600 is located at the position of the fusion splice 400, and the lifting and positioning component 600 is used to position the optical fiber and transfer the cut optical fiber.

[0051] See also Figure 1 As shown, there are two cutting components 200, two pushing limit components 300 and two lifting and positioning components 600. Specifically, the two lifting and positioning components 600 are located between the cutting positions of the two cutting components 200, and the two lifting and positioning components 600 are spaced apart. The two pushing limit components 300 are located on both sides of the two lifting and positioning components 600. Furthermore, there are two welding parts 400, and the two welding parts 400 are located between the two lifting and positioning components 600, and the connecting line between the two welding parts 400 is perpendicular to the connecting line between the two lifting and positioning components 600.

[0052] Continue reading Figure 1As shown, when welding is required, firstly, the two optical fibers to be welded are placed and fixed on the two push-limiting assemblies 300 respectively, and the ends of the two optical fibers are located on the lifting and positioning assemblies 600. The ends of the optical fibers are positioned and fixed by the lifting and positioning assemblies 600. Next, the cutting assembly 200 adjusts the cutting angle according to the different optical fibers, and then the optical fibers located on the left and right sides are cut by the cutting assembly 200 to obtain the preset optical fiber cutting end faces. Next, since the cut optical fibers are located on the lifting and positioning assemblies 600, the lifting and positioning assemblies 600 are lifted and lowered. The positioning assembly 600 moves the cut optical fiber to below the surface of the rack 100 so as to avoid movement interference with the subsequent welding process. Next, the push-limiting assemblies 300 on both sides move closer to each other so that the two cut ends of the optical fibers are located between the two welding pieces 400. The image acquisition module 500 captures the image of the cut end face of the optical fiber, and then the captured image is analyzed to determine whether it meets the requirements. If it meets the requirements, the two optical fibers are welded together through the welding piece 400; if it does not meet the requirements, it needs to be re-cut until it meets the preset requirements and is screwed for welding.

[0053] In this embodiment, the fusion splice 400 is an electrode rod, and the optical fiber fusion splicing is achieved by the high temperature generated between the two electrode rods. The two fusion splices 400 are distributed front and back.

[0054] Furthermore, the present application also includes a corresponding processor module, which can control the cutting component 200, the pushing limit component 300, the welding component 400, the image acquisition module 500 and the lifting and positioning component 600 to coordinate and work together. The processor module here can be understood as a control device such as a computer that can process corresponding data.

[0055] like Figure 6 and Figure 7 As shown, in this embodiment, the end face of the cut optical fiber can be an inclined surface or a circular surface, which can be selected according to different types of optical fibers.

[0056] In one embodiment, since the cut end face of the optical fiber is relatively small, it needs to be enlarged and then the image is captured. Therefore, the image capture module 500 may use an electronic limiting mirror as a component for image capture.

[0057] The cutting assembly 200 includes a first rotating driving member 210, a rotating member 220 is installed at the rotating end of the first rotating driving member 210, a second rotating driving member 230 is installed at the end of the rotating member 220 away from the first rotating driving member 210, a cutter 240 is installed at the rotating end of the second rotating driving member 230, and the second rotating driving member 230 is used to drive the cutter 240 to rotate and adjust the angle between the cutter 240 and the axis of the optical fiber.

[0058] See also Figure 1 and Figure 2 As shown, in order to meet the needs, the second rotary drive member 230 drives the cutter 240 to rotate so as to adjust the angle between the cutter 240 and the optical fiber, so as to cut different optical fiber cutting end faces.

[0059] Specifically, when it is necessary to cut the optical fiber, the processor module can control the second rotating drive member 230 to drive the cutter 240 to rotate to a certain angle according to preset parameters, and then the first rotating drive member 210 drives the rotating member 220 to rotate in the direction of the optical fiber, so that the optical fiber is cut by the cutter 240. After cutting, in order not to affect the subsequent movement and welding of the optical fiber, the rotating member 220 is driven by the first rotating drive member 210 to rotate in the opposite direction after the cutting is completed. Specifically, the first rotating drive member 210 can drive the rotating member 220, the second rotating drive member 230 and the cutter 240 to rotate and move below the surface of the frame 100. Accordingly, the frame 100 should be provided with corresponding avoidance grooves to allow the rotating member 220 to pass through and enter below the surface of the frame 100.

[0060] In this embodiment, a mounting block is installed at the rotating end of the second rotating drive member 230, and the cutter 240 is detachably mounted on the mounting block; in order to achieve rotation, the first rotating drive member 210 and the second rotating drive member 230 can both be servo motors, that is, any component that can achieve rotational motion while meeting the precision requirements can be used, and no specific limitation is made here.

[0061] The push-limiting assembly 300 includes a linear drive module 310, a first support member 320 is installed at the movable end of the linear drive module 310, a first pressing member 330 is rotatably installed on the first support member 320, a first limiting groove 340 is opened on the surface of the first support member 320, and the rotating end of the first pressing member 330 is detachably connected to the first support member 320.

[0062] After the optical fibers are cut and qualified, the cut end faces of the two optical fibers need to be brought close to the fusion position of the fusion splicer 400 . Specifically, the optical fibers located thereon are driven to move by pushing the limiting assembly 300 .

[0063] See also Figure 4 As shown, in order to prevent the optical fiber from moving before cutting, a first limiting groove 340 is opened on the first supporting member 320, and the optical fiber is located in the first limiting groove 340 and is limited by the first pressing member 330. After the optical fiber is limited in the first limiting groove 340, the optical fibers on both sides can be driven to move closer to each other by the linear driving modules 310 on both sides, so that the cut end face is located at the fusion position of the fusion member 400 to wait for fusion.

[0064] In this embodiment, the cross section of the first limiting groove 340 is "V"-shaped, which can accurately position the circular optical fiber and prevent the optical fiber from shifting.

[0065] A convenient disassembly structure 350 is provided between the first pressing member 330 and the first supporting member 320, and the convenient disassembly structure 350 includes a screwing member 351 threadedly connected to the first pressing member 330, and a knob 352 is fixedly provided at the end of the screwing member 351 away from the first pressing member 330, and an elastic telescopic member 353 is sleeved on the outer surface of the screwing member 351, and the elastic telescopic member 353 abuts between the screwing member 351 and the knob 352, and a connecting hole is opened on the first supporting member 320, and the screwing member 351 is inserted into the connecting hole.

[0066] Continue reading Figure 4 As shown, in order to prevent the first pressing member 330 from rotating and separating from the first supporting member 320 and being unable to limit the optical fiber located in the first limiting groove 340, it is necessary to fix the first pressing member 330 and the first supporting member 320. Specifically, the screwing member 351 can be driven to move toward the first supporting member 320 by screwing the knob 352, and then the first supporting member 320 can be screwed into the connection in the first supporting member 320. In this embodiment, the screwing member 351 can be a bolt, and the connecting hole on the first supporting member 320 can be a threaded hole, that is, the connection between the first pressing member 330 and the first supporting member 320 is achieved by using a bolt and a threaded hole connection method.

[0067] Furthermore, in order to make the screwing member 351 more stable when being screwed, an elastic and retractable member 353 may be provided on the outer surface of the screwing member 351. In the present embodiment, the elastic and retractable member 353 is a spring, specifically a compression spring.

[0068] The rotating end of the first pressing member 330 is magnetically connected to the first supporting member 320 .

[0069] Continue reading Figure 4 As shown, there are a variety of ways to connect the first carrier 320 and the first pressing member 330 without separating. Specifically, a magnet can be set on the first carrier 320 and / or the first carrier 320, so that the first carrier 320 and the first pressing member 330 are magnetically connected. Furthermore, when a magnet is set on the first pressing member 330, a magnetic attraction member matching it needs to be set on the first carrier 320; when a magnet is set on the first carrier 320, a magnetic attraction member matching it needs to be set on the first pressing member 330; when magnets are set on both the first carrier 320 and the first pressing member 330, the magnetism of the magnetic surfaces of the two magnets is opposite. It can be understood that the above-mentioned magnetic attraction member can be an iron product that can be attracted by a magnet, such as an iron sheet, an iron plate, etc.

[0070] The lifting and positioning assembly 600 includes a lifting module 610, a lifting end of which is mounted a second supporting member 620, a second pressing member 630 is rotatably mounted on the second supporting member 620, a second limiting groove 640 is provided on the surface of the second supporting member 620, and the rotating end of the second pressing member 630 is magnetically connected to the second supporting member 620.

[0071] See also Figure 1 , Figure 3 and Figure 5 As shown, after the optical fibers on the left and right sides are cut, the cut parts are located on the lifting and positioning assembly 600, and because the lifting and positioning assembly 600 is located at the dissolving position at this time, it is necessary to move the cut parts of the optical fibers to other positions for avoidance.

[0072] In this embodiment, the end of the optical fiber on each side is located in the second limiting groove 640, and the cross-section of the second limiting groove 640 is "V"-shaped. The second pressing member 630 is rotated to combine with the second supporting member 620, so that the part to be cut off is limited in the second limiting groove 640. After the cutting is completed, the second supporting member 620 can be driven down by the lifting module 610, so that the second supporting member 620 and the second pressing member 630 are moved below the surface of the frame 100, thereby achieving avoidance of subsequent welding.

[0073] In this embodiment, the second pressing member 630 and the second supporting member 620 are connected by magnetic attraction. Specifically, a magnet can be used to connect the two.

[0074] For example, the lifting module 610 can be a component capable of achieving linear movement, such as a motor screw module, and the specific type is not limited here.

[0075] The frame 100 is fixedly mounted with a third rotating driving member 800 , and the image acquisition module 500 is mounted on the moving end of the third rotating driving member 800 .

[0076] See also Figure 3 As shown, in order to be able to capture images of the optical fiber cutting end faces at different positions, it is necessary to drive the image capture module 500 to move its position. Specifically, this can be achieved by driving the image capture module 500 to rotate through the third rotating drive member 800. The third rotating drive member 800 can also be replaced by a linear module, that is, the linear module drives the image capture module 500 to move in a straight line to achieve position adjustment. Furthermore, the position adjustment of the image capture module 500 can also be achieved by combining rotation and linear motion. The third rotating drive member 800 can be a motor as a rotational power source, and other types of rotational power sources can also be selected, which are not limited here.

[0077] A cover plate 900 is rotatably mounted on the frame 100 , and a light source 700 is fixedly mounted on the cover plate 900 .

[0078] See also Figure 1 and Figure 3 As shown, in order to enable the image acquisition module 500 to acquire clearer images, it is necessary to provide supplementary light to the image acquisition module 500. Specifically, the light source 700 on the cover plate 900 can be used to illuminate the module to provide a lighting environment.

[0079] It should be noted here that after the optical fiber is placed on the push-limit assembly 300, the cover 900 can be covered to prevent external dust from entering the cutting and welding environment. At this time, after the cover 900 is covered, the light source 700 can be started at the same time to provide a lighting environment for the image acquisition module 500. Furthermore, the light source 700 can be an LED lamp bead or other component.

[0080] A ventilation net 1000 is disposed on the side wall of the frame 100 . The ventilation net 1000 is communicated with the interior of the frame 100 . A handle 1100 is fixedly disposed on the side of the frame 100 .

[0081] See also Figure 1 As shown, the air entering the rack 100 is filtered through the ventilation net 1000 to prevent larger dust from entering the rack 100 , and the rack 100 is connected to the external environment through the ventilation net 1000 , thereby achieving heat dissipation of various components inside the rack 100 .

[0082] In one embodiment, in order to facilitate the transportation of the rack 100 , the handles 1100 on both sides can be used as fulcrums for grabbing and carrying, making the movement of the rack 100 more convenient.

[0083] Continue reading Figure 1 As shown, in order to facilitate control, a display control panel 1200 can be installed on the rack 100 as an operation interface.

[0084] The present application also provides a fiber fusion splicing method, which uses the fiber fusion splicing device described in any of the above embodiments to fusion splice optical fibers. The fiber fusion splicing method includes:

[0085] S100: Obtain the optical fiber diameter;

[0086] S200: Setting cutting parameters and fusion parameters according to the acquired optical fiber diameter, and uploading the optical fiber diameter, the cutting parameters and the fusion parameters to a data storage module;

[0087] S300: the cutting component (200) automatically cuts the optical fiber to obtain a cut end face of the optical fiber;

[0088] S400: Capturing an image of the cut end face of the optical fiber, and transmitting the captured image to the data storage module;

[0089] S500: comparing the acquired image with a preset image to obtain a comparison result, and if the comparison result meets the preset requirement, performing a welding step; if the comparison result does not meet the preset requirement, resetting the cutting parameters until the preset requirement is met;

[0090] S600: The fusion splicer 400 performs fusion splicing on the optical fibers that meet the requirements;

[0091] S700: Take out the optical fiber after the fusion splicing is completed.

[0092] See also Figure 8 As shown, in the present application, different push-limiting assemblies 300 and lifting and positioning assemblies 600 are selected according to the different diameters of the optical fibers, so as to facilitate the fixation of the optical fibers. The cutting parameters mentioned above can be the moving speed of the optical fiber driven by the push-limiting assembly 300, the inclination angle of the cutter 240, etc., and the welding parameters are the discharge voltage, current and other parameters.

[0093] The present application first selects the cutting parameters and welding parameters preset in the storage module according to the optical fibers of different diameters, and the selected parameters are automatically uploaded to the data storage module as subsequent operation log records. Of course, in practice, the above parameters can also be adjusted autonomously through the display control panel 1200, which is not limited here. After the cutting parameters and welding parameters are adjusted, the processor module controls the cutting component 200 to cut the optical fiber. After cutting, the image acquisition module 500 is used to capture an image of the cut end face of the optical fiber. The data storage module has an image of the preset cut end face. The captured image is compared with the preset image in the data storage module to obtain a result of whether it meets the welding requirements. If the cut end face of the optical fiber meets the requirements, welding is performed, that is, the optical fiber is welded through the welding component 400. If the cut end face of the optical fiber does not meet the requirements, the cutting parameters need to be readjusted until the cut end face of the optical fiber meets the welding requirements. After the welding is completed, the welded optical fiber can be manually removed.
