Description

Technical Field

[0001] The utility model belongs to the technical field related to the manufacture of optical fiber loops, and more specifically, relates to a tooling for winding optical fiber loops. Background Art

[0002] An optical fiber loop is an optical fiber structure in which an optical fiber is bent into a loop to meet specific optical path requirements. It is commonly used in fields such as optical fiber sensors, optical fiber lasers, and optical fiber amplifiers to achieve the transmission, processing, control, and distribution of optical signals, and plays a very important role.

[0003] In the prior art, most optical fiber loops are customized products and need to be made using a skeleton. The skeleton has boss grooves designed for fiber layer transition and fiber bypass. The design of the boss grooves can reduce the stress during the winding process of the optical fiber loop and improve the performance of the optical fiber loop. However, currently, the outer diameters of optical fibers vary greatly. Once the depth of the boss grooves on the skeleton is determined, the same boss depth cannot meet the requirements for winding thin-diameter optical fibers and ordinary optical fibers. When different outer diameters of optical fibers are selected, the depth of the boss grooves cannot match the corresponding outer diameter of the optical fiber, resulting in an impact on the performance of the final optical fiber loop. In addition, there are also process requirements for the flatness of the side wall of the optical fiber loop during assembly, so sometimes the number of bosses needs to be adjusted; in the prior art, when the assembly process changes, the number of bosses cannot be adjusted correspondingly, resulting in the inapplicability of the tooling and affecting the assembly. Summary of the Utility Model

[0009] As a further preference of the present utility model, the initial state of the slider is located within the boss groove reserved on the skeleton and is flush with the inner wall of the skeleton; when winding the fiber optic ring, a part of the slider moves within the boss groove and changes from the flush state to a non-flush state, while the other sliders remain in the initial state, thereby realizing the adjustment of the depth and / or quantity combination of the boss groove.

[0010] As a further preference of the present utility model, the robotic arms are respectively arranged on both sides of the skeleton, and the robotic arms on each side are used to drive the four sliders.

[0011] As a further preference of the present utility model, the above-mentioned fiber optic ring winding tooling is used to realize the free adjustment of a single boss groove or four boss grooves.

[0012] As a further preference of the present utility model, the above-mentioned fiber optic ring winding tooling can cooperate with a fiber optic outer diameter detection mechanism, which is used to identify the outer diameter of the wound fiber optic.

[0013] As a further preference of the present utility model, the above-mentioned fiber optic ring winding tooling can cooperate with a curing mechanism, which is arranged at the top of the fiber optic ring to directly irradiate the fiber optic ring, and after the curing is completed, the corresponding multiple sliders are simultaneously separated from the fiber optic ring body by the robotic arm.

[0014] As a further preference of the present utility model, the above-mentioned fiber optic ring winding tooling further includes a control system, wherein the control system is connected to the robotic arm and is used to determine the sliders that do not need to be adjusted according to the assembly data, and / or is used to drive the robotic arm according to the fiber optic outer diameter data and then change the position of the slider within the boss groove.

[0015] As a further preference of the present utility model, the control system is also connected to a curing detection mechanism and is used to drive the slider to separate from the boss groove according to the curing completion signal detected by the curing detection mechanism.

[0031] In this application, unless otherwise clearly specified and limited, terms such as "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] Refer to Figures 1-4, the optical fiber winding tooling in the present utility model mainly includes a skeleton 1, a plurality of boss grooves 2 and an adjusting mechanism 3. Specifically, the skeleton 1 may include two side cover plates 101 and a cylindrical connecting block 102 located in the middle. The two side cover plates 101 and the connecting block 102 are on the same axis. On the side of the two side cover plates 101 close to each other, there are connecting grooves for the connecting block 102 to be embedded. A plurality of boss grooves 2 are evenly arranged on the side cover plates 101 in the skeleton 1. In this embodiment, for example, four boss grooves 2 are arranged on each side cover plate 101, and under the drive of the adjusting mechanism 3, the groove depth and / or the number combination can be independently and controllably adjusted to match the outer diameters of various wound optical fibers.

[0033] More specifically, the adjusting mechanism 3 is a robotic arm. The robotic arms are respectively arranged on both sides of the skeleton 1. The robotic arms on each side are used to drive the four sliders 4. When adjusting the number, they are driven separately, and when adjusting the depth, they are driven simultaneously. The depth and / or the number of the boss grooves 2 are adjusted through the reciprocating movement of these sliders 4. For example, the robotic arm has four robotic claws 301, which respectively correspond to the four boss grooves 2 to adjust the groove depth and / or the number combination.

[0034] See Figure 1 and Figure 4 , in this embodiment, the end of the robotic claw 301 is rotatably connected with a screw rod 302, and the screw rod 302 is in threaded connection with the slider 4. Thus, the robotic claw 301 and the slider 4 are connected as a whole. In this way, when the robotic claw 301 moves, it can drive the slider 4 to move in the corresponding boss groove 2, and further realize the change of the boss groove depth and / or the number combination.

[0035] More specifically, the initial states of the respective sliders 4 are located in the boss grooves 2 reserved on the skeleton 1 and are flush with the inner wall of the skeleton 1, that is, the inner surface of the corresponding side cover plate 101. When winding the optical fiber ring, first determine the number of bosses according to the optical fiber ring assembly process, and then determine the groove depth according to the outer diameter of the optical fiber. After the data receiving system receives the information about the number of bosses, a part of the sliders 4 are driven by the control system to move up and down in the boss grooves 2, changing the bosses to be adjusted from the flush state to the non-flush state. When the control system receives the optical fiber outer diameter data from the data receiving system, it controls the sliders to adjust the boss groove depth to match the optical fiber outer diameter data, and further realizes the adjustment of the depth of the boss grooves 2. The control system can be a PLC or a single-chip microcomputer. After the adjustment is completed, based on the groove depth that is adjusted in place and matches the size of the optical fiber outer diameter, the subsequent optical fiber winding process is performed. This winding process is a well-known conventional process in the art and will not be elaborated here.

[0036] Furthermore, the optical fiber winding tooling preferably further includes an optical fiber outer diameter detection mechanism, which is used to identify the outer diameter of the wound optical fiber, for example, an image recognition unit.

[0037] More specifically, the detection system receives an external assembly process. During the assembly process, it is necessary to ensure the flatness of the horizontal placement of the fiber optic loop, so the number of bosses needs to be adjusted. The detection system transmits the requirement for the number of bosses to the control system, and the control system drives the sliders in the corresponding slots to adjust the number of bosses. For the sliders that do not need to be adjusted, they remain in the initial flush state.

[0038] Through the above design, on the one hand, the movement of the slider 4 can be used to achieve the purpose of variable groove depth of the corresponding boss, thus solving the problem that the depth of the boss groove 2 cannot be changed in the prior art. At the same time, it can further cooperate with the fiber optic outer diameter detection mechanism to automatically adjust the positions of the sliders 4, thereby more precisely controlling the depth of the boss groove 2. On the other hand, these sliders 4 can also be combined to adjust the number of boss grooves 2, thus synchronously solving the problem that the number of boss grooves 2 cannot be changed in the prior art.

[0039] In addition, in the prior art, there is often a problem of difficult demolding of the fiber optic loop, especially for small-sized fiber optic loops. In the present utility model, the above-mentioned fiber optic loop winding tooling can cooperate with a curing mechanism. The curing mechanism is arranged at the top of the fiber optic loop for direct irradiation of the fiber optic loop. After curing is completed, the corresponding multiple sliders 4 are simultaneously detached from the fiber optic loop body by the robotic arm. By moving the slider 4, the slider 4 can be quickly and automatically controlled to be detached after the fiber optic loop is cured, reducing the contact area between the fiber optic loop and the skeleton 1, facilitating the demolding of the skeleton 1, and thus being particularly suitable for the winding of small-sized fiber optic loops.

[0040] For example, after the fiber optic loop winding is completed, the fiber optic loop is directly irradiated by the ultraviolet curing lamp at the top of the fiber optic loop to complete the curing of the fiber optic loop. After the curing is completed, for example, the signal of the completion of curing can be detected by the detection system, and the robotic claw drive system drives the four robotic claws 301 on both sides of the skeleton 1, so that the corresponding sliders are detached from the boss grooves on the skeleton, and then the eight sliders 4 are detached from the loop body.

[0041] Furthermore, the above-mentioned fiber optic loop winding tooling further includes a control system, wherein the control system is connected to the robotic arm and is used to determine the sliders 4 that do not need to be adjusted according to the assembly data, and / or is used to drive the robotic arm according to the fiber optic outer diameter data to change the position of the slider 4 in the boss groove 2.

[0042] In addition, the control system is also connected to the curing detection mechanism and is used to drive the slider 4 to detach from the boss groove 2 according to the curing completion signal detected by the curing detection mechanism.

[0043] In summary, the optical fiber winding tooling according to the present utility model can realize the required adjustment of the depth and / or quantity combination of a plurality of boss grooves 2 by redesigning its entire structural composition and setting method, thereby significantly improving the processing freedom of the types and specifications of optical fiber rings; the overall structure of the optical fiber winding tooling is compact and easy to operate, effectively overcoming the problems in existing products that only optical fiber rings with one outer diameter can be wound and the number of boss grooves 2 cannot be adjusted, etc., which helps to improve the performance quality of the wound optical fiber rings, and thus has good practical value and application prospects.

[0044] It is easy for those skilled in the art to understand that the above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
