Description

Technical Field

[0001] The utility model relates to an optical fiber ring carrier, in particular to a carrier structure for winding an optical fiber ring. Background Art

[0002] During the fiber optic ring winding process, the bobbin serves as the fundamental support structure for fiber optic winding. The accuracy of its positioning on the rotating shaft directly impacts the winding quality and ultimate performance of the fiber optic ring. In traditional winding equipment, the connection between the bobbin and the rotating shaft often has gaps or is loose, causing the bobbin to vibrate and deflect during high-speed rotation, thus affecting the uniformity of the fiber winding and the positioning accuracy. Utility Model Content

[0003] The purpose of the utility model is to provide a carrier structure for winding an optical fiber ring. The technical problem to be solved is how to improve the positioning accuracy of the skeleton during the fiber winding process, thereby improving the winding quality and performance of the optical fiber ring.

[0004] The utility model is achieved through the following technical solutions:

[0005] A carrier structure for winding an optical fiber ring, the carrier structure being connected to a rotating shaft having a first positioning tapered hole formed therein. When the rotating shaft rotates, the frame is driven to rotate, and the optical fiber is wound around the frame. The carrier structure comprises a frame, a first auxiliary wheel, a second auxiliary wheel, and a locking screw. The frame, the first auxiliary wheel, and the second auxiliary wheel are all provided with a center hole.

[0006] The locking screws pass through the center holes of the first auxiliary wheel, the frame, and the second auxiliary wheel in sequence, fixing the first auxiliary wheel and the second auxiliary wheel to the two ends of the frame;

[0007] One end of the locking screw extending out of the second auxiliary wheel is used to connect to the rotating shaft;

[0008] The end surface of the second auxiliary wheel away from the frame is provided with a first positioning frustum, and the first positioning frustum is used to fit into the first positioning conical hole on the rotating shaft.

[0009] The frame, first auxiliary wheel, and second auxiliary wheel are each provided with a center hole. A locking screw passes sequentially through the center holes of the first auxiliary wheel, frame, and second auxiliary wheel, allowing the first auxiliary wheel, frame, and second auxiliary wheel to rotate about the same axis during the winding process, thereby reducing rotational instability caused by axis deviation. The conical surface of the first positioning cone mates with the first positioning cone hole, allowing the frame to automatically adjust and maintain high coaxiality during rotation, effectively reducing deviation caused by installation errors or vibration, thereby improving the positioning accuracy of the frame on the rotating shaft. The locking screw not only connects the first auxiliary wheel, frame, and second auxiliary wheel, but also connects the rotating shaft. This through-connection eliminates the impact of intermediate components on connection stability. Since vibration is a significant factor affecting positioning accuracy and winding quality, the conical surface fit and the rigid connection of the locking screw help reduce vibration during rotation, improve the positioning accuracy of the frame on the rotating shaft, ensure that the optical fiber is evenly wound around the frame according to the predetermined trajectory and tension during the winding process, and reduce problems such as fiber crossing, overlapping, or loosening caused by inaccurate positioning. This not only improves the appearance quality of the fiber ring but also enhances its optical performance.

[0010] Furthermore, the frame includes a first plate, a second plate, and a third plate connected in sequence, the first plate being connected to the first auxiliary wheel, and the third plate being connected to the second auxiliary wheel;

[0011] The side walls of the first plate and the third plate extend beyond the side wall of the second plate;

[0012] The second plate side wall and the first plate and the third plate extending from the second plate side wall together form an optical fiber winding groove, which is used to accommodate optical fibers.

[0013] The optical fiber winding groove formed by the side walls of the second plate and the first plate and the third plate extending from the side walls of the second plate provides a clear and restricted winding path for the optical fiber, which helps to maintain uniform and stable tension of the optical fiber during the winding process, and avoids problems such as crossing, overlapping or loosening of the optical fiber due to uneven tension or unstable path; the side walls of the first plate and the third plate extend from the side walls of the second plate, which increases the boundary constraints of the optical fiber winding groove, so that the optical fiber is closer to the contour of the optical fiber winding groove during winding, thereby improving the uniformity and consistency of the optical fiber arrangement, and further improving the optical performance of the optical fiber ring; the optical fiber winding groove not only provides a winding path for the optical fiber, but also plays a role in accommodating the optical fiber. After the optical fiber winding is completed, the optical fiber can be neatly arranged in the optical fiber winding groove, which is convenient for subsequent fixation and management, and helps to reduce damage and confusion of the optical fiber during subsequent processing.

[0014] Furthermore, the first auxiliary wheel and the second auxiliary wheel are both provided with a limiting groove at one end close to the frame;

[0015] The first plate is used to be inserted into the limiting groove of the first auxiliary wheel, and the second plate is used to be inserted into the limiting groove of the second auxiliary wheel.

[0016] By cooperating with the above-mentioned limiting groove and the first plate and the second plate, the alignment and connection between the skeleton and the auxiliary wheel are achieved, so that the skeleton, the first auxiliary wheel and the second auxiliary wheel form a tight whole, reducing the shaking or deviation of the skeleton caused by the loose connection of the locking screw, thereby improving the stability during the fiber winding process; the locking screw is used to limit the axial movement of the skeleton, and the limiting groove is used to limit the radial movement of the skeleton, further improving the positioning accuracy of the skeleton on the rotating axis. The multi-directional limiting helps to maintain uniform tension and trajectory of the optical fiber during the winding process, avoiding problems such as optical fiber crossing, overlapping or loosening due to inaccurate positioning; the existence of the limiting groove makes the positioning of the skeleton more convenient. The skeleton is inserted into the two limiting grooves to achieve radial limitation of the skeleton, and the first positioning cone is inserted into the first positioning cone hole to achieve radial limitation of the second auxiliary wheel. At this time, the center holes of the second auxiliary wheel, the skeleton and the first auxiliary wheel are on the same axis, and the locking screw can be directly inserted.

[0017] Furthermore, when the first plate is inserted into the limiting groove of the first auxiliary wheel and the second plate is inserted into the limiting groove of the second auxiliary wheel, the limiting groove wall of the first auxiliary wheel contacts the end surface of the first plate away from the second plate and the side wall of the first plate, and the limiting groove wall of the second auxiliary wheel contacts the end surface of the second plate away from the first plate and the side wall of the second plate;

[0018] The gap between the opposite end surfaces of the first auxiliary wheel and the second auxiliary wheel forms a winding auxiliary groove;

[0019] Extending outward from the optical fiber winding groove, the groove width of the winding auxiliary groove gradually increases.

[0020] When the above-mentioned first plate and second plate are respectively inserted into the limiting grooves of the first auxiliary wheel and the second auxiliary wheel, the groove walls of the limiting grooves contact not only the end faces of the plates, but also the side walls, ensuring a close fit between the skeleton and the auxiliary wheels, effectively preventing the skeleton from moving or offsetting during the winding process, thereby improving positioning accuracy and stability; the above-mentioned winding auxiliary groove provides an additional space for optical fiber winding, and the winding auxiliary groove is connected to the optical fiber winding groove, so that the optical fiber can transition more smoothly during the winding process, avoiding sudden changes in optical fiber tension or damage caused by sudden changes in the winding path; when the winding auxiliary groove extends outward from the optical fiber winding groove, the groove width gradually increases, which helps the optical fiber to gradually release tension during the winding process, so that the optical fiber maintains a relatively uniform tension distribution in the winding groove; the gradual groove width of the winding auxiliary groove also makes the path of the optical fiber smoother during the winding process, reducing friction and wear between the optical fiber and the winding structure.

[0021] Furthermore, the end surface of the frame close to the second auxiliary wheel is provided with a second positioning cone, the end surface of the second auxiliary wheel close to the frame is provided with a second positioning cone hole adapted to fit with the second positioning cone, and the second positioning cone is used to be inserted into the second positioning cone hole.

[0022] In addition to the previously mentioned coordination between the first positioning cone and the first positioning tapered hole between the second auxiliary wheel and the rotating shaft, the bobbin and the second auxiliary wheel are now also positioned via the coordination between the second positioning cone and the second positioning tapered hole. This dual positioning mechanism improves the overall positioning accuracy of the bobbin on the rotating shaft, ensuring stability and consistency during fiber winding. The conical surface coordination between the second positioning cone and the second positioning tapered hole is self-locking, maintaining a tight connection during rotation and preventing loosening. This helps reduce bobbin displacement or shaking caused by vibration or external forces, thereby improving the stability and reliability of fiber winding. The conical surface coordination helps evenly distribute stress across the entire contact surface during rotation, reducing local stress concentration and extending the service life of the bobbin and auxiliary wheel. The coordination between the second positioning cone and the second positioning tapered hole simplifies and expedits the installation and commissioning of the bobbin and the second auxiliary wheel, allowing operators to easily achieve alignment and fixation, improving work efficiency and accuracy.

[0023] Furthermore, when the second positioning frustum is inserted into the second positioning conical hole, the axes of the first positioning frustum and the second positioning frustum coincide with the axis of the skeleton.

[0024] The axes of the first positioning cone and the second positioning cone coincide with the axis of the skeleton, which means that the skeleton and the auxiliary wheel are coaxially arranged; since axis deviation may cause uneven distribution of optical fiber tension or offset of the winding trajectory, the improvement of coaxiality enables the optical fiber to follow a stable trajectory during the winding process, reducing the winding error caused by axis deviation, helping to improve the winding accuracy of the optical fiber ring, and thus improving its optical performance; coaxiality ensures the uniformity and stability of optical fiber winding; during the installation process, the first positioning cone and the first positioning cone hole, the second positioning cone and the second positioning cone hole can be used to quickly align and fix the rotating shaft, the second auxiliary wheel and the skeleton, so that the axes of the rotating shaft, the second auxiliary wheel and the skeleton coincide, thereby achieving a coaxial setting.

[0025] Furthermore, first fiber guide grooves are provided on the side walls of the first auxiliary wheel and the second auxiliary wheel.

[0026] The above-mentioned first fiber guide groove provides a accommodating groove for the optical fiber to be wound; in order to adapt to the diversity of optical fiber winding, a two-end fiber winding method is usually adopted. There is a fiber changing operation during the fiber winding process. At a certain moment, the optical fiber at one end is directly wound on the skeleton, and the optical fiber at the other end is not wound on the skeleton. The optical fiber not wound on the skeleton is stuck in the first fiber guide groove to achieve positioning, avoiding problems such as looseness and disorder of the optical fiber at this end due to centrifugal force during the fiber winding process; the first fiber guide groove can provide certain support and protection for the optical fiber, reduce direct contact and friction between the optical fiber and the surrounding environment, help reduce wear and damage of the optical fiber, and extend the service life of the optical fiber ring.

[0027] Furthermore, the end surfaces of the first auxiliary wheel and the second auxiliary wheel close to the frame are both provided with second fiber guide grooves, and the first fiber guide grooves and the second fiber guide grooves are connected; and the connection between the first fiber guide grooves and the second fiber guide grooves is arc-shaped.

[0028] The above-mentioned first fiber guide groove and second fiber guide groove serve together as a accommodating groove for the optical fiber to be wound. The length direction of the first fiber guide groove is the same as the extension direction of the optical fiber to be wound, and the length direction of the second fiber guide groove is different from the extension direction of the optical fiber to be wound. When the optical fiber to be wound is limited in the fiber guide groove, the optical fiber to be wound is transitioned through the arc surface to reduce optical fiber wear.

[0029] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0030] The frame, first auxiliary wheel, and second auxiliary wheel are each provided with a center hole. A locking screw, passing sequentially through the center holes of the first auxiliary wheel, frame, and second auxiliary wheel, allows the first auxiliary wheel, frame, and second auxiliary wheel to rotate about the same axis during the winding process, reducing rotational instability caused by axis deviation. The conical surface of the first positioning cone mates with the first positioning cone hole, allowing the frame to automatically adjust and maintain high coaxiality during rotation, effectively reducing deviation caused by installation errors or vibration, thereby improving the positioning accuracy of the frame on the rotating shaft. The locking screw not only connects the first auxiliary wheel, frame, and second auxiliary wheel, but also connects the carrier structure to the rotating shaft. This through-connection eliminates the impact of intermediate components on connection stability. Since vibration is a significant factor affecting positioning accuracy and winding quality, the conical surface fit and the rigid connection of the locking screw help reduce vibration during rotation, improve the positioning accuracy of the frame on the rotating shaft, ensure that the optical fiber is evenly wound around the frame according to the predetermined trajectory and tension during the winding process, and reduce problems such as fiber crossing, overlapping, or loosening caused by inaccurate positioning. This not only improves the appearance quality of the fiber ring but also enhances its optical performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0038] Example 1

[0039] This embodiment 1 provides a carrier structure for winding an optical fiber ring, combined with Figure 1 and Figure 3 The carrier structure is used to connect with the rotating shaft 1. The rotating shaft 1 is provided with a first positioning tapered hole 62. When the rotating shaft 1 rotates, it drives the skeleton 3 to rotate, and the optical fiber is wound around the skeleton 3. The carrier structure includes the skeleton 3, the first auxiliary wheel 2, the second auxiliary wheel 4 and the locking screw 5. The skeleton 3, the first auxiliary wheel 2 and the second auxiliary wheel 4 are all provided with a center hole.

[0040] The locking screw 5 passes through the center holes of the first auxiliary wheel 2, the frame 3, and the second auxiliary wheel 4 in sequence, fixing the first auxiliary wheel 2 and the second auxiliary wheel 4 to both ends of the frame 3;

[0041] One end of the locking screw 5 extending out of the second auxiliary wheel 4 is used to connect to the rotating shaft 1;

[0042] A first positioning cone 61 is provided on the end surface of the second auxiliary wheel 4 away from the frame 3 . The first positioning cone 61 is used to fit into the first positioning cone hole 62 on the rotating shaft 1 .

[0043] The skeleton 3, the first auxiliary wheel 2, and the second auxiliary wheel 4 are all provided with a center hole. The locking screw 5 passes through the center holes of the first auxiliary wheel 2, the skeleton 3, and the second auxiliary wheel 4 in sequence, so that the first auxiliary wheel 2, the skeleton 3, and the second auxiliary wheel 4 rotate around the same axis during the winding process, reducing the rotation instability caused by the axis deviation. The first positioning cone 61 cooperates with the conical surface of the first positioning cone hole 62, so that the skeleton 3 can automatically adjust and maintain a high coaxiality during the rotation process, effectively reducing the deviation caused by installation error or vibration, thereby improving the positioning accuracy of the skeleton 3 on the rotating shaft 1. The locking screw 5 not only serves to connect the first auxiliary wheel 2. The skeleton 3 and the second auxiliary wheel 4 also serve to connect the carrier structure to the rotating shaft 1. The through-type connection avoids the influence of intermediate components on the connection stability. Since vibration is an important factor affecting positioning accuracy and winding quality, the rigid connection of the conical surface fit and the locking screw 5 helps to reduce vibration during rotation, improves the positioning accuracy of the skeleton 3 on the rotating shaft 1, ensures that the optical fiber can be evenly wound around the skeleton 3 according to the predetermined trajectory and tension during the winding process, and reduces problems such as optical fiber crossing, overlapping or loosening caused by inaccurate positioning. This not only improves the appearance quality of the optical fiber ring, but also enhances its optical performance.

[0044] Example 2

[0045] On the basis of Example 1, combined Figure 1 The skeleton 3 includes a first plate 31, a second plate 32, and a third plate 33 connected in sequence. The first plate 31 is connected to the first auxiliary wheel 2, and the third plate 33 is connected to the second auxiliary wheel 4.

[0046] The side walls of the first plate 31 and the third plate 33 extend beyond the side walls of the second plate 32;

[0047] The side wall of the second plate 32 and the first plate 31 and the third plate 33 extending from the side wall of the second plate 32 together form an optical fiber winding groove 34 for accommodating optical fibers.

[0048] The optical fiber winding groove 34 formed by the side walls of the above-mentioned second plate 32 and the first plate 31 and the third plate 33 extending from the side walls of the second plate 32 provides a clear and restricted winding path for the optical fiber, which helps to maintain uniform and stable tension of the optical fiber during the winding process, and avoids problems such as crossing, overlapping or loosening of the optical fiber due to uneven tension or unstable path; the side walls of the first plate 31 and the third plate 33 extend from the side walls of the second plate 32, increasing the boundary constraints of the optical fiber winding groove 34, so that the optical fiber is closer to the contour of the optical fiber winding groove 34 during winding, thereby improving the uniformity and consistency of the optical fiber arrangement, and further improving the optical performance of the optical fiber ring; the optical fiber winding groove 34 not only provides a winding path for the optical fiber, but also plays the role of accommodating the optical fiber. After the optical fiber winding is completed, the optical fiber can be neatly arranged in the optical fiber winding groove 34, which is convenient for subsequent fixation and management, and helps to reduce damage and confusion of the optical fiber during subsequent processing.

[0049] Example 3

[0050] On the basis of Example 2, the first auxiliary wheel 2 and the second auxiliary wheel 4 are both provided with a limiting groove 21 at one end close to the frame 3;

[0051] The first plate 31 is used to be inserted into the limiting groove 21 of the first auxiliary wheel 2 , and the second plate 32 is used to be inserted into the limiting groove 21 of the second auxiliary wheel 4 .

[0052] The restraining grooves 21 cooperate with the first plate 31 and the second plate 32 to achieve alignment and connection between the skeleton 3 and the auxiliary wheel, forming a tight whole with the skeleton 3, the first auxiliary wheel 2, and the second auxiliary wheel 4. This reduces shaking or deviation of the skeleton 3 caused by a loose connection of the locking screw 5, thereby improving stability during fiber winding. The locking screw 5 is used to limit the axial movement of the skeleton 3, while the restraining grooves 21 are used to limit the radial movement of the skeleton 3, further improving the positioning accuracy of the skeleton 3 on the rotating shaft 1. The multi-directional restraining helps maintain uniform tension and trajectory of the optical fiber during winding, avoiding problems such as fiber crossing, overlapping, or loosening caused by inaccurate positioning. The restraining grooves 21 facilitate positioning of the skeleton 3. Inserting the skeleton 3 into the two restraining grooves 21 radially restrains the skeleton 3. Inserting the first positioning cone 61 into the first positioning cone hole 62 radially restrains the second auxiliary wheel 4. At this point, the center holes of the second auxiliary wheel 4, the skeleton 3, and the first auxiliary wheel 2 are coaxial, allowing for direct insertion of the restraining screw 5.

[0053] In a specific embodiment, when the first plate 31 is inserted into the limiting groove 21 of the first auxiliary wheel 2 and the second plate 32 is inserted into the limiting groove 21 of the second auxiliary wheel 4, the groove wall of the limiting groove 21 of the first auxiliary wheel 2 contacts the end surface of the first plate 31 away from the second plate 32 and the side wall of the first plate 31, and the groove wall of the limiting groove 21 of the second auxiliary wheel 4 contacts the end surface of the second plate 32 away from the first plate 31 and the side wall of the second plate 32;

[0054] The gap between the opposite end surfaces of the first auxiliary wheel 2 and the second auxiliary wheel 4 forms a winding auxiliary groove 35;

[0055] Extending outward from the optical fiber winding groove 34 , the groove width of the winding auxiliary groove 35 gradually increases.

[0056] When the first plate 31 and the second plate 32 are respectively inserted into the limiting grooves 21 of the first auxiliary wheel 2 and the second auxiliary wheel 4, the groove walls of the limiting grooves 21 are in contact not only with the end faces of the plates, but also with the side walls, ensuring a close fit between the skeleton 3 and the auxiliary wheels, effectively preventing the skeleton 3 from moving or offsetting during the winding process, thereby improving positioning accuracy and stability; the above-mentioned winding auxiliary groove 35 provides an additional space for optical fiber winding, and the winding auxiliary groove 35 is connected to the optical fiber winding groove 34, so that the optical fiber can transition more smoothly during the winding process, avoiding sudden changes in optical fiber tension or damage caused by sudden changes in the winding path; when the winding auxiliary groove 35 extends outward from the optical fiber winding groove 34, the groove width gradually increases, which helps the optical fiber to gradually release tension during the winding process, so that the optical fiber maintains a relatively uniform tension distribution in the winding groove; the gradual groove width of the winding auxiliary groove 35 also makes the path of the optical fiber smoother during the winding process, reducing friction and wear between the optical fiber and the winding structure.

[0057] Example 4

[0058] Based on any of the above embodiments, the end surface of the above-mentioned skeleton 3 close to the second auxiliary wheel 4 is provided with a second positioning cone 63, and the end surface of the second auxiliary wheel 4 close to the skeleton 3 is provided with a second positioning cone hole 64 adapted to adapt to the second positioning cone 63. The above-mentioned second positioning cone 63 is used to be inserted into the second positioning cone hole 64.

[0059] In addition to the previously mentioned coordination between the first positioning cone 61 and the first positioning tapered hole 62 between the second auxiliary wheel 4 and the rotating shaft 1, the bobbin 3 and the second auxiliary wheel 4 are now also positioned via the coordination between the second positioning cone 63 and the second positioning tapered hole 64. This dual positioning mechanism improves the overall positioning accuracy of the bobbin 3 on the rotating shaft 1, ensuring stability and consistency during the fiber winding process. The conical surface coordination between the second positioning cone 63 and the second positioning tapered hole 64 is self-locking, maintaining a tight connection during rotation and preventing loosening. This helps reduce displacement or shaking of the bobbin 3 caused by vibration or external forces, thereby improving the stability and reliability of fiber winding. The conical surface coordination helps evenly distribute stress across the entire contact surface during rotation, reducing local stress concentration and extending the service life of the bobbin 3 and the auxiliary wheel. The coordination between the second positioning cone 63 and the second positioning tapered hole 64 simplifies and expedits the installation and commissioning of the bobbin 3 and the second auxiliary wheel 4, allowing operators to easily achieve alignment and securement, improving work efficiency and accuracy.

[0060] In a specific embodiment, when the second positioning frustum 63 is inserted into the second positioning conical hole 64 , the axes of the first positioning frustum 61 and the second positioning frustum 63 coincide with the axis of the frame 3 .

[0061] The axes of the first positioning cone 61 and the second positioning cone 63 mentioned above coincide with the axis of the skeleton 3, which means that the skeleton 3 and the auxiliary wheel are coaxially arranged; since the axis deviation may cause uneven distribution of optical fiber tension or deviation of the winding trajectory, the improvement of coaxiality enables the optical fiber to follow a stable trajectory during the winding process, reducing the winding error caused by axis deviation, helping to improve the winding accuracy of the optical fiber ring, and thus improving its optical performance; coaxiality ensures the uniformity and stability of the optical fiber winding; during the installation process, the first positioning cone 61 and the first positioning cone hole 62, the second positioning cone 63 and the second positioning cone hole 64 can be used to quickly align and fix the rotating shaft 1, the second auxiliary wheel 4 and the skeleton 3, so that the axes of the rotating shaft 1, the second auxiliary wheel 4 and the skeleton 3 coincide, thereby achieving a coaxial setting.

[0062] Example 5

[0063] On the basis of Example 3 or Example 4, the side walls of the first auxiliary wheel 2 and the second auxiliary wheel 4 are provided with first fiber guide grooves 22, such as Figure 2 As shown; the first fiber guide groove 22 can be one or more.

[0064] The above-mentioned first fiber guide groove 22 provides a accommodating groove for the optical fiber to be wound; in order to adapt to the diversity of optical fiber winding, a two-end fiber winding method is usually adopted, and there is a fiber changing operation during the fiber winding process. At a certain moment, the optical fiber at one end is directly wound on the skeleton 3, and the optical fiber at the other end is not wound on the skeleton 3. The optical fiber not wound on the skeleton 3 is stuck in the first fiber guide groove 22 to achieve positioning, avoiding problems such as looseness and confusion of the optical fiber at this end due to centrifugal force during the fiber winding process; the first fiber guide groove 22 can provide certain support and protection for the optical fiber, reduce direct contact and friction between the optical fiber and the surrounding environment, help reduce wear and damage of the optical fiber, and extend the service life of the optical fiber ring.

[0065] Specific embodiments, such as Figure 2 As shown, the end surfaces of the first auxiliary wheel 2 and the second auxiliary wheel 4 close to the frame 3 are both provided with a second fiber guide groove 23, and the first fiber guide groove 22 and the second fiber guide groove 23 are connected; the connection between the first fiber guide groove 22 and the second fiber guide groove 23 is arc-shaped.

[0066] The above-mentioned first fiber guide groove 22 and second fiber guide groove 23 serve together as a receiving groove for the optical fiber to be wound. The length direction of the first fiber guide groove 22 is the same as the extension direction of the optical fiber to be wound, and the length direction of the second fiber guide groove 23 is different from the extension direction of the optical fiber to be wound. When the optical fiber to be wound is limited in the fiber guide groove, the optical fiber to be wound is transitioned through the arc surface to reduce optical fiber wear.

[0067] A specific example for reference is that the optical fiber ring is obtained by winding the fiber at both ends, and there are two optical fiber supply devices for providing optical fiber, and the two optical fiber supply devices are connected by an optical fiber; when one of the optical fiber supply devices serves as the delivery end and delivers the optical fiber at this end to the skeleton 3, the other optical fiber supply device serves as the fixed end and does not deliver the optical fiber at this end to the outside, and the optical fiber supply device as the fixed end is set on the rotating shaft 1 and rotates synchronously with the skeleton 3; the optical fiber at the fixed end extends to the skeleton 3 through the first fiber guide groove 22 and the second fiber guide groove 23, and the optical fiber at the delivery end extends to the skeleton 3 and continuously delivers the optical fiber at this end, and the delivered optical fiber is wound around the skeleton 3 as the skeleton 3 rotates.

[0068] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
