Description

Technical Field

[0001] This invention relates to the field of optical fiber winding, and in particular to a variable turn zone position control device and its method of use for optical fiber winding. Background Technology

[0002] Fiber optic gyroscopes are high-precision inertial sensing systems used to measure attitude and orientation. The fiber optic loop is the core optical component of a fiber optic gyroscope. A fiber optic loop is a fiber optic sensing element made by winding a section of optical fiber using special winding methods such as four-pole symmetry, octole symmetry, or sixteen-pole symmetry. The amount of optical fiber required for different specifications of fiber optic loops varies from hundreds of meters to several kilometers. The number of winding layers in a fiber optic loop is generally an integer multiple of the number of poles, with each layer containing dozens of turns of optical fiber, and each turn of fiber is tightly bonded together.

[0003] During the winding process, the midpoint of the fiber length must first be marked, and the fibers at both ends of this midpoint are wound onto two fiber storage trays respectively. Then, starting from the midpoint, the fibers on the two storage trays are alternately wound onto the fiber ring frame according to the corresponding winding method. During the winding process, when one storage tray is in the working state for fiber feeding and winding, the other storage tray needs to enter the following state and rotate synchronously with the fiber ring frame until the working storage tray finishes winding its current layer. When it is necessary to change trays, the working positions and working states of the two storage trays are exchanged. This tray changing action can be completed automatically by a fully automatic winding machine or manually by a semi-automatic winding machine.

[0004] In fiber optic winding, there's a concept called the variable-turn zone. Since actual fiber optic rings aren't uniformly arranged in a spiral pattern, but rather each turn of fiber is mostly on the same plane, only changing turns to the next plane within a small area, the variable-turn zone is formed by this transition range for each turn and each layer of fiber. The process requires this variable-turn zone to be neat and uniform to improve fiber optic ring performance. The angle of the variable-turn zone on the circumference of the fiber optic ring is generally no more than 10°. In actual winding, there's no good way to control the variable-turn zone, which is prone to shifting, thus affecting fiber optic ring performance. To ensure that the transition range of each layer and each turn of fiber is within the designated variable-turn zone, operators use tools to intervene, rolling fibers that have deviated from the variable-turn zone into it. This operation applies external force to the fiber optic ring, causing uneven stress distribution within the ring, leading to non-reciprocal phase errors and reducing fiber optic ring performance. Summary of the Invention

[0005] This invention provides a variable-turn area position control device and its usage method for optical fiber winding, which solves the problem of variable-turn area position control during optical fiber winding.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a variable turn zone position control device for optical fiber winding, comprising a skeleton mechanism, the skeleton mechanism comprising a first skeleton flange and a second skeleton flange, a shaft tube provided between the first skeleton flange and the second skeleton flange, a first variable turn groove and a second variable turn groove respectively provided on the inner side of the first skeleton flange and the second skeleton flange, a first fiber control plate and a second fiber control plate respectively provided on the outer side of the first skeleton flange and the second skeleton flange, both the first fiber control plate and the second fiber control plate are provided with a first comb-shaped sliding groove and a second comb-shaped sliding groove for optical fiber to pass through, the first comb-shaped sliding groove and the second comb-shaped sliding groove being located on both sides of the first variable turn groove or the second variable turn groove.

[0007] In the preferred embodiment, the outer side of the shaft tube is provided with a first skeleton petal and a second skeleton petal, which are spliced ​​together to form a complete circular structure. The end faces of the first skeleton petal and the second skeleton petal are connected to the first skeleton flange and the second skeleton flange.

[0008] In a preferred embodiment, a detachable septum is provided at the joint between the first and second skeletal petals.

[0009] In a preferred embodiment, a tension holding mechanism is connected to the outside of the first and second fiber control discs, and the tension holding mechanism is provided with a cylindrical boss for mounting the following fiber storage disc.

[0010] In the preferred embodiment, the cylindrical boss is rotatably connected to the fiber storage tray. The tension holding mechanism is provided with a slide rail, and a slidable slider is provided on the slide rail. A rotatable movable pulley is connected to the slider. A spring column is provided at one end of the tension holding mechanism near the skeleton mechanism, and a spring is also provided. The two ends of the spring are connected to the spring column and the slider, respectively. A first fixed pulley and a second fixed pulley are respectively provided on both sides of the movable pulley on the tension holding mechanism. The optical fiber following the fiber storage tray passes around the first fixed pulley, the second fixed pulley and the movable pulley.

[0011] In the preferred embodiment, a scale is provided on one side of the slide rail of the tension holding mechanism.

[0012] In a preferred embodiment, the tension holding mechanism is provided with a sliding sleeve, inside which is a slidable screw. One end of the screw is provided with a rocker arm, and a second fixed pulley is provided at the end of the rocker arm. A locking nut is fitted on the screw, and the end of the locking nut abuts against the sliding sleeve.

[0013] In the preferred scheme, Select appropriate skeleton flanges, skeleton flaps, and fiber control discs to assemble a variable turn zone control assembly; Install fiber storage trays, optical fibers leading out from each fiber storage tray, and variable turn area control components. By rotating the two fiber storage trays, the midpoint of the marked optical fiber between the two fiber storage trays is moved into the variable turn groove that is against the frame flange on one side. Distribute working fiber storage trays and following fiber storage trays; Control the fiber tension between the two fiber storage trays and the frame; The loop winding process begins, and the equipment will automatically control the fiber tension between the working fiber storage tray and the frame during the loop winding process. Complete multiple reel changes and fiber winding operations until the target number of layers is reached.

[0014] The preferred solution includes a manual disc changing method: The working fiber storage tray is manually disassembled and the optical fiber between it and the frame is carefully coiled on the working fiber storage tray and temporarily placed on the equipment platform. Disassemble the fiber storage tray and install it in the fiber laying position of the equipment. Carefully lay the optical fiber between the fiber storage tray and the frame in the fiber laying system of the equipment. Move the working fiber storage tray from the equipment platform to the correct tension holding mechanism, introduce the optical fiber into the correct chute bottom, and then introduce it into the tension control wheel group on the tension holding mechanism and adjust the optical fiber tension. This realizes the manual exchange of the working position and working status of the two fiber storage trays.

[0015] The beneficial effects of the present invention are as follows: the fiber control disk can control the variable turn area. The first fiber control disk and the second fiber control disk can guide the optical fiber to enter the correct comb-shaped slide groove according to different skeleton diameters and slide safely into the bottom of the groove, or slide out from the bottom of the groove to the working position. Each groove bottom can control the optical fiber variable turn area within a certain range. The fiber control tray has a wide range of applications. The principle of the fiber control tray is to set up multiple sliding grooves. By introducing the optical fiber into the bottom of the correct sliding groove, the positioning control of the optical fiber in the variable turn area can be realized. This structure is not only suitable for equipment that automatically replaces the fiber storage tray, but also for equipment that manually replaces the fiber storage tray. The semi-automatic winding machine has tension control for the optical fiber led out from the fiber storage tray. After the tension corresponding to the slider at different positions on the scale is pre-calibrated, the position of the slider can be easily adjusted by adjusting the length of the optical fiber between the fiber storage tray and the frame, thereby adjusting the tension value of the optical fiber between the fiber storage tray and the frame. Balancing fiber tension and improving the quality of the fiber loop: Through the tension control mechanism, the fiber following the fiber storage tray and the frame can maintain a constant tension when rotating synchronously with the fiber loop frame. Adjusting this tension to be consistent with the fiber tension of the working fiber storage tray makes the tension between the fiber loop and the two fiber storage trays balanced, which is more conducive to improving the stress distribution symmetry of the fiber loop, thereby improving the performance of the fiber loop. Furthermore, by using constant tension, the tightening force and fiber angle of the fiber in the variable turn area are controlled, and the position of the variable turn area is constrained. Protecting the optical fiber: Due to the buffering effect of the spring, it can absorb the fiber vibration caused by equipment vibration, which helps to protect the optical fiber between the fiber storage tray and the frame.

Detailed Implementation

[0036] Example 1: like Figure 1-18 In the present invention, a variable turn zone position control device for optical fiber winding includes a skeleton mechanism 12, the skeleton mechanism 12 including a first skeleton flange 3 and a second skeleton flange 4, a shaft tube 302 is provided between the first skeleton flange 3 and the second skeleton flange 4, a first variable turn groove 301 and a second variable turn groove 401 are respectively provided on the inner side of the first skeleton flange 3 and the second skeleton flange 4, a first fiber control plate 1 and a second fiber control plate 2 are respectively provided on the outer side of the first skeleton flange 3 and the second skeleton flange 4, and a first comb-shaped sliding groove 101 and a second comb-shaped sliding groove 104 for optical fiber to pass through are provided on both sides of the first variable turn groove 301 or the second variable turn groove 401.

[0037] The position of the bottom end of each comb-shaped groove varies along both the circumferential and radial directions.

[0038] When the outermost fiber of each layer is turned, it will bulge outward. The existence of the turning groove ensures that the turning area is controlled within the groove, preventing crowded and messy arrangement. The outside of the turning groove is a comb-shaped slide groove arranged in a mirror. The fiber starts to loop from the midpoint of its length. The working fiber storage tray 11 automatically adjusts the rotation speed to release the fiber to the skeleton. The following fiber storage tray 10 rotates synchronously with the skeleton ring on the same axis. The fiber at the end of the following fiber storage tray 10 passes through the turning and then exits from the comb-shaped slide groove, further restricting the arrangement position of the turning area.

[0039] In the preferred embodiment, the outer side of the shaft tube 302 is provided with a first skeleton petal 5 and a second skeleton petal 6, which are spliced ​​together to form a complete circular structure. The end faces of the first skeleton petal 5 and the second skeleton petal 6 are connected to the first skeleton flange 3 and the second skeleton flange 4.

[0040] The optical fiber is wound around the outside of the circular structure. After the optical fiber is wound, the first fiber control disc 1, the second fiber control disc 2, the first skeleton flange 3, and the second skeleton flange 4 can be removed. Then the shaft tube 302, the first skeleton lobe 5, and the second skeleton lobe 6 can be removed to make a skeletonless ring.

[0041] In a preferred embodiment, a detachable partition 501 is provided at the joint between the first skeleton petal 5 and the second skeleton petal 6.

[0042] After the first fiber control disc 1, the second fiber control disc 2, the first skeleton flange 3, the second skeleton flange 4, and the shaft tube 302 are removed, the partition 501 is pulled out from between the first skeleton petal 5 and the second skeleton petal 6. Since there is a gap between the first skeleton petal 5 and the second skeleton petal 6, it is easier to demold from the skeletonless ring.

[0043] During the fiber winding process, fiber tension is a key technical indicator determining the performance and quality of the fiber ring. Excessive fiber tension fluctuations can cause uneven stress distribution within the fiber ring, leading to non-reciprocal phase errors and reducing fiber ring performance. Ideally, fiber tension fluctuations during winding should be minimized. Existing semi-automatic winding equipment and processes can only ensure controlled fiber tension between the fiber storage tray and the fiber ring frame during the winding process. The fiber between the other fiber storage tray and the fiber ring frame is merely secured with tape to prevent loosening, without tension control. This situation easily leads to uneven stress distribution within the fiber ring, affecting its performance.

[0044] This effect is also reflected in the variable-turn zone, especially in the winding of the first few turns of each layer.

[0045] In a preferred embodiment, a tension holding mechanism 7 is connected to the outside of the first fiber control disc 1 and the second fiber control disc 2. The tension holding mechanism 7 is provided with a cylindrical boss 702 for mounting the following fiber storage disc 10.

[0046] In a preferred embodiment, the cylindrical boss 702 is rotatably connected to the fiber storage tray 10. The tension holding mechanism 7 is provided with a slide rail 707, and a slidable slider 706 is provided on the slide rail 707. A rotatable movable pulley 705 is connected to the slider 706. A spring column 708 is provided at one end of the tension holding mechanism 7 near the skeleton mechanism 12, and a spring 709 is also provided. The two ends of the spring 709 are respectively connected to the spring column 708 and the slider 706. A rotatable first fixed pulley 703 and a second fixed pulley 704 are respectively provided on both sides of the movable pulley 705 on the tension holding mechanism 7. The optical fiber following the fiber storage tray 10 passes around the first fixed pulley 703, the second fixed pulley 704 and the movable pulley 705.

[0047] The fixed pulley on the corresponding side is determined based on which of the first comb-shaped groove 101 and the second comb-shaped groove 104 is used.

[0048] In the preferred embodiment, a scale 710 is provided on one side of the slide rail 707 of the tension holding mechanism 7.

[0049] The distance that slider 706 is pulled can reflect the magnitude of the pulling force.

[0050] In a preferred embodiment, the tension holding mechanism 7 is provided with a sliding sleeve 712, and a slidable screw 714 is provided inside the sliding sleeve 712. One end of the screw 714 is provided with a rocker arm 711, and a second fixed pulley 704 is provided at the end of the rocker arm 711. A locking nut 713 is sleeved on the screw 714, and the end of the locking nut 713 abuts against the sliding sleeve 712.

[0051] One of the first fixed pulley 703 and the second fixed pulley 704 is tilted towards the first comb-shaped groove 101 or the second comb-shaped groove 104. The tilt angle is adjusted according to the different positions of the comb-shaped grooves to prevent the optical fiber from coming out of the pulley groove.

[0052] The locking nut 713 is threadedly connected to the screw 714. The extension length of the screw 714 is adjustable. The hinge shafts of the rocker arm 711 and the screw 714 are threaded ends and nuts are installed to lock the angle of the rocker arm 711.

[0053] The steps for using the device are as follows: 1. Select appropriate skeleton flanges, skeleton lobes, and fiber control discs according to the fiber optic ring specifications and assemble them into a variable turn zone control assembly; 2. For the fully automatic winding machine, install two fiber storage trays, the optical fibers led out from each fiber storage tray, and the variable turn area control components on the equipment. By rotating the two fiber storage trays, the midpoint of the optical fiber marked between the two fiber storage trays is moved into the variable turn groove that is against the frame flange on one side. 3. The fully automatic fiber winding machine starts winding. During the winding process, the equipment will automatically allocate working fiber storage trays and following fiber storage trays and automatically control the fiber tension between the two fiber storage trays and the frame. 4. When a reel needs to be changed, the fully automatic winding machine controls the two fiber storage reels to move around the variable turn area control component in a plane, thereby automatically guiding the fiber of the fiber storage reel switched to the following state into the comb-shaped slide groove and placing it at the bottom of the groove, and leading the fiber of the fiber storage reel switched to the working state out from the bottom of the comb-shaped slide groove to the fiber release position. 5. For a semi-automatic winding machine, install two fiber storage trays, the optical fibers led out from each fiber storage tray, two sets of tension holding mechanisms, and variable turn area control components on the equipment. The optical fibers led out from the working fiber storage tray are laid in the fiber laying system of the equipment. The optical fibers led out from the fiber storage tray are laid on the tension holding mechanism adjacent to the fiber control tray through the correct sliding groove of the fiber control tray. By rotating the two fiber storage trays, the midpoint of the optical fiber marked between the two fiber storage trays is moved to the variable turn groove against the frame flange on one side. 6. Rotate the fiber storage tray to adjust the tension of the optical fiber led out from the fiber storage tray to be consistent with the tension of the fiber delivery system of the equipment; 7. The semi-automatic fiber winding machine starts winding. During the winding process, the equipment will automatically control the fiber tension between the working fiber storage tray and the frame. The tension maintaining mechanism can ensure that the fiber tension following the fiber storage tray is constant. 8. When a reel replacement is required, the semi-automatic winding machine is stopped. First, the working fiber storage reel is manually disassembled and the fiber between it and the frame is carefully wound onto the working fiber storage reel and temporarily placed on the equipment platform. Then, the following fiber storage reel is disassembled and installed in the fiber laying position of the equipment. The fiber between the following fiber storage reel and the frame is carefully laid in the fiber laying system of the equipment. Finally, the working fiber storage reel is moved from the equipment platform to the correct tension holding mechanism. The fiber is introduced into the correct chute bottom and then into the tension control wheel group on the tension holding mechanism. The fiber tension is adjusted. This completes the manual exchange of the working positions and working states of the two fiber storage reels.

[0054] 9. After completing multiple reel changes and fiber winding operations on a fully automatic or semi-automatic winding machine until the target number of layers is achieved, proceed to the glue curing and ring removal process. First, remove the two fiber storage reels and the variable turn area control component. Remove the first and second fiber control reels respectively. Remove the optical fibers from the two fiber storage reels and wind them onto the shaft tubes outside the first and second frame flanges. Then, take the frame mechanism to the curing equipment for glue curing. After the fiber ring is cured into a whole, remove the second frame flange, the first frame flange, and the frame petals in sequence to finally obtain the frameless fiber ring product.

[0055] Example 2: like Figure 1-10In this paper, an optical fiber positioning device for optical fiber winding includes a first skeleton flange 3, on which a shaft tube 302 is provided. The shaft tube 302 is coaxially engaged with a first skeleton lobe 5 and a second skeleton lobe 6. The first skeleton lobe 5 and the second skeleton lobe 6 can form a cylinder on the shaft tube 302. A second skeleton flange 4 is fitted onto the shaft tube 302 and coaxially connected with the first skeleton lobe 5 and the second skeleton lobe 6. The first skeleton flange 3, the first skeleton lobe 5, the second skeleton lobe 6, and the second skeleton flange 4 form a skeleton mechanism 12 and constitute an annular groove 303 for supporting the winding. The fiber optic ring has a first skeleton flange 3 coaxially connected to a first fiber control disc 1, with the first skeleton flange 3 partially embedded in the first fiber control disc 1. The second skeleton flange 4 is coaxially connected to a second fiber control disc 2, with the second skeleton flange 4 partially embedded in the second fiber control disc 2. The first fiber control disc 1, the skeleton mechanism 12, and the second fiber control disc 2 together form a variable turn zone control component 13. The first fiber control disc 1 is provided with a first comb-shaped slide groove 101 and a second comb-shaped slide groove 104 arranged in a mirror image. The first comb-shaped slide groove 101 and the second comb-shaped slide groove 104 contain 6 arc-shaped slide grooves. The first fiber control disc 1 and the second fiber control disc 2 have the same structure.

[0056] For ease of description of the control of the variable turn zone, the guide wheel structure device from the following fiber storage tray 10, the working fiber storage tray 11 to the frame mechanism 12 is omitted, such as Figure 9 As shown, during the winding process, firstly, the midpoints of the optical fibers of the following fiber storage tray 10 and the working fiber storage tray 11 are controlled to rest in the first variable-turn groove 301 of the first frame flange 3 of the frame mechanism, and the working fiber 807 is tangent to the cylinder formed by the first frame lobe 5 and the second frame lobe 6. Then, the frame mechanism 12 is driven to rotate counterclockwise to the right, and the following fiber storage tray 10 and the frame mechanism 12 rotate synchronously along the frame axis. The working fiber storage tray 11 releases the working fiber 807 to the frame mechanism 12 for winding until the optical fiber in this layer has wound a specified number of turns and all movements stop. During the winding process, the first turn of optical fiber is close to the side wall of the first frame flange 3. When the working fiber 807 transitions from the first turn to the second turn, it will contact and squeeze the following fiber 802 in the area of ​​the first variable-turn groove 301. The second turn of working fiber 807 will naturally have a slanted variable-turn situation. All subsequent optical fibers in this layer will continue this slanted variable-turn situation, forming the variable-turn area of ​​the optical fiber ring. Through theoretical research and practice, it has been found that the key to controlling the variable turn region lies in the fiber entry position and angle of the follower fiber 802, and the tangent position between the follower fiber 802 and the fiber ring, which is the variable turn position of the fiber ring.

[0057] To facilitate the description of the principle of the comb-shaped groove arrangement, the following is hidden. Figure 1 The second fiber control disc 2 and the second skeleton flange 4 of the variable turn zone control assembly are shown, as follows: Figure 8As shown, a variable turn zone control angle 801 with an angle of 5° is set centrally within the first variable turn zone 301. When the working fiber 807 released by the working fiber storage disk 11 via the fiber guide wheel 806 enters the minimum circumference 803 of the fiber guide composed of the first skeleton petal 5 and the second skeleton petal 6, the following fiber 802 led out by the following fiber storage disk 10 is introduced through the lowest groove of the second comb-shaped groove 104 and is tangent to the minimum circumference 803 of the fiber guide. The tangency point is located at the intersection of the left edge of the variable turn zone control angle 801 and the minimum circumference 803 of the fiber guide; with the second Starting from the lowest groove of the comb-shaped groove 104, a vertical line is drawn to the right edge of the variable turn zone control angle 801. With the axis of the skeleton mechanism as the center, the maximum circumference 805 of the fiber guide passing through the aforementioned vertical foot can be obtained. The fiber guide circumference range 804 between the minimum fiber guide circumference 803 and the maximum fiber guide circumference 805 is the fiber ring diameter range that the lowest groove of the second comb-shaped groove 104 can controllably satisfy the requirements of the variable turn zone control angle 801. The maximum fiber guide angle of the following fiber 802 within the fiber guide circumference range 804 is 5°. In addition, when the working fiber 807 is tangent to the minimum circumference 803 and the maximum circumference 805 of the fiber guide, it will form two intersection points with the circumference of the fiber control disk 1. When the fully automatic winding machine changes the position of the robotic arm A and the robotic arm B around the variable turn area control component 13, the optical fiber between these two intersection points can automatically enter the lowest groove of the first comb-shaped slide 101. The first comb-shaped slide 101 and the second comb-shaped slide 104 are mirror images of the first variable turn groove 301. Therefore, the working fiber 807 of this layer will be converted into the following fiber 802 of the next layer of fiber ring, and the working fiber storage disk 11 of this layer will be converted into the following fiber storage disk 10 of the next layer. The following fiber 802 of this layer will slide out of the second comb-shaped slide 104 as the robotic arm changes, so that the following fiber 802 of this layer will be converted into the working fiber 807 of the next layer of fiber ring, and the following fiber storage disk 10 of this layer will be converted into the working fiber storage disk 11 of the next layer. By controlling the distances from the first comb-shaped groove 101 and the second comb-shaped groove 104 to the first variable-turn groove 301, the annular thickness of the fiber guide circumference range 804 can be controlled, thereby allowing the calculation of the number of fiber layers in the variable-turn region that each comb-shaped groove can control.

[0058] Similarly, by increasing the number of the first comb-shaped slide groove 101 and the second comb-shaped slide groove 104, the control requirements of the variable turn area within different fiber ring diameter ranges can be met.

[0059] For a fully automatic fiber winding machine, the working fiber storage tray 11 and the following fiber storage tray 10 are respectively arranged on robotic arms A and B, and robotic arms A and B can move flexibly around the frame in a plane, combining multiple working modes. A typical working mode is as follows: Figure 10 As shown, in Figure 10 In states -① and 10-③, robotic arm A rotates coaxially and synchronously with the frame, forming a fiber take-up mechanism; robotic arm B, acting as a fiber release mechanism, releases optical fibers onto the frame mechanism 12; Figure 10In states 10-② and 10-④, robotic arm B rotates synchronously and coaxially with the frame, forming a fiber take-up mechanism; robotic arm A acts as a fiber release mechanism, releasing optical fibers onto the frame mechanism 12. The difference between 10-① and 10-③ is that the rotation direction of robotic arm B to the frame mechanism 12 is opposite, which is related to the winding process; the difference between 10-② and 10-④ is similar. These four working modes can be applied to four-pole symmetry, octole symmetry, and sixteen-pole symmetry fiber winding methods through mode switching.

[0060] Example 3: Using a fully automatic winding machine and a sixteen-pole winding method, optical fibers with an outer diameter of 135 micrometers are selected for winding. The inner diameter of the fiber ring is 30 millimeters, and 64 layers are wound, with 60 turns per layer. The width of the first variable turn groove 301 and the second variable turn groove 401 are 5 millimeters, and the depth is 250 micrometers. The angle of the variable turn zone control angle 801 is 4°. The normal distance from the bottom of the first comb-shaped slide groove 101 and the second comb-shaped slide groove 104 to the variable turn zone control angle 801 is 40 millimeters. Through calculation, it can be found that the maximum fiber guiding angle of the following fiber 802 within the fiber guiding circumference range 804 is also 4°. The thickness of the circular ring of the fiber guiding circumference range 804 is about 2.79 millimeters. Theoretically, 2.79 millimeters can accommodate 23 layers of optical fibers with an outer diameter of 135 micrometers tightly packed together. By adding a set of slots 2.79 mm vertically upwards from the lowest slot of the first comb-shaped slot 101 and the second comb-shaped slot 104, the variable turn area control of the 24th to 46th layers of optical fiber can be satisfied. By controlling the slot opening size of the newly added slots, the automatic insertion of the 24th to 46th layers of optical fiber can be achieved. Similarly, only three sets of slots in the first comb-shaped slot 101 and the second comb-shaped slot 104 are needed to satisfy the variable turn area control of 64 layers of optical fiber.

[0061] Considering that the fiber diameter may vary due to errors during the actual looping process, and that the working fiber 807 may also experience slight jitter, fault tolerance is required when setting the first comb-shaped slot 101 and the second comb-shaped slot 104. That is, when switching between adjacent slots, the control of the variable turn area must be guaranteed regardless of which of the two slots the fiber slides into. Therefore, four sets of slots are set for the first comb-shaped slot 101 and the second comb-shaped slot 104. The bottom spacing of adjacent slots is 2.2 mm. Each slot can accommodate 18 layers of fiber with an outer diameter of 135 micrometers. There is an overlap space of about 0.5 mm between adjacent slots for variable turn area control, which can meet the variable turn tolerance of 4 layers of fiber.

[0062] Example 4: like Figure 11-16In this process, a four-pole winding method is adopted, with a winding tension of 10 grams. A semi-automatic winding machine is used for winding. An optical fiber with an outer diameter of 165 micrometers is selected for winding. The inner diameter of the optical fiber ring is 50 millimeters. 40 layers are wound, with 72 turns per layer. The width of the first variable turn groove 301 and the second variable turn groove 401 are 6 millimeters, and the depth is 250 micrometers. The variable turn area control angle 801 is 5°. The normal distance from the bottom of the first comb-shaped slide groove 101 and the second comb-shaped slide groove 104 to the variable turn area control angle 801 is 50 millimeters. Through calculation, it can be found that the maximum fiber guiding angle of the following fiber 802 within the fiber guiding circumference range 804 is also 5°.

[0063] For the semi-automatic winding machine, the fiber take-up mechanism X and the fiber release mechanism Y are in fixed positions, and the fiber storage tray can only be changed manually. In order to achieve precise control of the variable turn zone and tension control of the following fiber, the first fiber control tray 1 is structurally modified to enlarge the fiber inlet to facilitate manual introduction of optical fiber, and two sets of tension holding mechanisms 7 are added. For the control of the variable turn zone, it is the same as in embodiment 2, except that the optical fiber needs to be manually introduced into or removed from the comb-shaped slide. The equipment can automatically calculate and display the correct slide number on the screen. For the tension control of the following fiber, tension holding mechanisms 7 are set on both sides of the variable turn zone control component 13, and are coaxially mounted on the take-up shaft of the fiber take-up mechanism X of the semi-automatic winding machine through the base shaft hole 701 and the shaft tube 302, and are tightened and fixed by nuts. The following fiber is passed through the first fixed pulley 703, the movable pulley 705, and the second fixed pulley 704 in sequence, and the following fiber storage tray 10 is mounted on the cylindrical boss 702. According to Hooke's Law, within the elastic limit, the elastic force of spring 709 is directly proportional to the change in elongation of spring 709. A suitable spring 709 is selected, and slider 706 is calibrated on scale 710 from 5g to 20g fiber tension. The tension of follower fiber 802 is adjusted to 10g by rotating follower fiber storage tray 10. Then, follower fiber storage tray 10 is fixed with handle screw 9, and winding begins. According to the winding process, the tension holding mechanisms 7 on both sides of the variable turn zone control component 13 are used alternately. During winding, the equipment controls the tension of working fiber 807 to 10g to achieve balance with the tension of follower fiber 802.

The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
