Abstract
Description
Technical Field
[0001] The utility model relates to an optical fiber winding device, in particular to a winding shaft component used for winding an optical fiber ring. Background Art
[0002] In fields such as fiber-optic communications and fiber-optic sensing, fiber optic rings are important optical components whose performance directly affects the stability and accuracy of the entire system. Traditional fiber optic ring systems often rely on manual operations or simple mechanical devices, making it difficult to achieve precise control of the fiber path. Specifically, there are the following challenges:
[0003] Because optical fiber materials are relatively fragile, they are easily affected by external forces and may break or be damaged during the winding process. When manually winding optical fiber rings, interference from human factors, such as hand shaking and uneven force, can not only easily cause the optical fiber path to deviate, affecting the geometric shape and optical performance of the optical fiber ring, but may also cause the optical fiber to break or be damaged. Although some mechanical devices can assist in optical fiber winding, they are limited by the complexity and precision of the mechanical structure, and it is often difficult to achieve precise control of the optical fiber path, especially in scenarios with high speed and high precision requirements, which can easily cause the optical fiber to be stretched or broken. Utility Model Content
[0004] The purpose of the utility model is to provide a winding shaft assembly for winding an optical fiber ring, and the technical problem to be solved is how to reduce the external force damage to the optical fiber during the winding process.
[0005] The utility model is achieved through the following technical solutions:
[0006] A winding shaft assembly for winding an optical fiber ring comprises a base plate and two parallel supporting plates, wherein the supporting plates are arranged on the base plate; a gap between the two supporting plates forms a winding area;
[0007] The support plate is provided with a driver, the output end of which is connected to a rotating shaft, which passes through the support column and extends to the winding area; the two rotating shafts are symmetrically arranged about the vertical plane of the winding area, and the two drivers operate synchronously;
[0008] A follower disk is sleeved on the rotating shaft. When the driver drives the rotating shaft to rotate, the rotating shaft drives the follower disk to rotate.
[0009] At least one of the rotating shafts is connected to an optical fiber winding shaft, and the optical fiber winding shaft is used to receive the optical fiber;
[0010] When the rotating shaft drives the optical fiber winding shaft to rotate, one end of the optical fiber is fixed on the follower disk, and the other end of the optical fiber is wound on the optical fiber winding shaft.
[0011] The two rotating shafts are symmetrical about the mid-vertical plane of the winding area, and the two drives operate synchronously, ensuring that the optical fiber can be wound evenly and smoothly on the optical fiber winding spool during the winding process, avoiding twisting, stretching or squeezing of the optical fiber due to inconsistent rotation speed or asymmetric position, thereby reducing the risk of damage to the optical fiber due to uneven force.
[0012] Before fiber winding, one end of the optical fiber is fixed to the corresponding follower disk and the other end is placed on the base plate. Then the driver is started and the fiber winding begins. The rotating shaft and the follower disk fixed to the rotating shaft rotate synchronously to ensure that the optical fiber fixed to the follower disk is not damaged while the fiber is being wound. The two rotating shafts must be completely synchronized throughout the entire fiber winding process. Otherwise, when the optical fiber is fixed on a follower disk without a fiber winding shaft, the optical fiber will be stretched or broken due to the lack of synchronization between the two rotating shafts.
[0013] Furthermore, the two rotating shafts rotate in the same direction to achieve synchronization, thereby preventing the optical fiber from being damaged or broken due to the two rotating shafts being out of sync.
[0014] Furthermore, the winding mode of the optical fiber on the optical fiber winding shaft is changed by switching the follower disk for fixing the optical fiber.
[0015] Furthermore, the follower disk includes a first connection area, a second connection area, and an edge area, wherein the first connection area is arranged in the central area of the follower disk, the second connection area is arranged around the first connection area, and the edge area is arranged at the edge of the follower disk;
[0016] The first connection area is used to connect the rotating shaft; the second connection area is used to fix the optical fiber; and the edge area extends outward from the second connection area, with a thickness gradually decreasing.
[0017] The above-mentioned first connection area is arranged in the central area of the follower disk, and the rotating shaft is connected to the first connection area, so that the follower disk can rotate smoothly with the rotation of the rotating shaft; if the rotating shaft is not connected to the central area of the follower disk, during the winding process, the distance between the follower disk and the optical fiber winding shaft is constantly changing, thereby causing the distance between the optical fiber fixing point on the follower disk and the optical fiber winding shaft to constantly change. Since one end of the optical fiber is fixed on the follower disk and the other end extends to the optical fiber winding shaft, when the distance between the optical fiber fixing point and the optical fiber winding shaft changes, the external force exerted on the optical fiber fixing end changes, causing this part of the optical fiber to be stretched or broken; the edge area is arranged at the edge of the follower disk, and the gradually decreasing thickness helps to reduce the weight of the follower disk, reduce the inertial force during rotation, and reduce the sudden change of optical fiber tension caused by inertia.
[0018] Furthermore, the edge of the follower plate is bent at an arc shape.
[0019] The above-mentioned follower disk may be affected by various factors and produce vibration or shaking during rotation. The curved edge design can better disperse and absorb vibration energy, reducing its impact on the optical fiber winding process; from the perspective of structural mechanics, the curved edge design can enhance the overall stability and rigidity of the follower disk, help reduce the deformation and vibration generated by the follower disk during high-speed rotation, and ensure the accuracy and reliability of optical fiber winding.
[0020] Furthermore, the above-mentioned driver includes a motor, a first synchronous pulley, a second synchronous pulley and a synchronous belt. The output shaft of the above-mentioned motor is connected to the first synchronous pulley, the above-mentioned second synchronous pulley is connected to the rotating shaft, and the above-mentioned first synchronous pulley and the second synchronous pulley are driven by the synchronous belt.
[0021] The transmission of the follower plate is achieved through the cooperation of the motor, the first synchronous pulley, the synchronous belt and the second synchronous pulley; the meshing transmission of the synchronous belt ensures the smoothness of the transmission.
[0022] Furthermore, the second synchronous pulley is connected to the support plate via a bearing.
[0023] Furthermore, the diameter of the first synchronous pulley is smaller than the diameter of the second synchronous pulley.
[0024] When the diameter of the above-mentioned first synchronous pulley is smaller than the diameter of the second synchronous pulley, due to the meshing of the synchronous belt with the teeth of the two synchronous pulleys, a reduction ratio will naturally be generated during the transmission process, which means that the output speed of the motor will be higher than the speed of the rotating shaft, and the torque obtained by the rotating shaft will increase accordingly; the design of the reduction ratio helps to adapt to different winding requirements, especially when a larger torque is required to drive the follower disk and the optical fiber winding shaft; due to the reduction ratio in the transmission process, the output torque of the motor will be amplified after passing through the synchronous belt drive; because the optical fiber needs to overcome a certain amount of resistance and friction during the winding process, especially when the optical fiber tension is large or the winding speed is high, the larger torque can ensure the smooth rotation of the follower disk and the optical fiber winding shaft, and reduce slippage or vibration caused by insufficient torque.
[0025] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0026] The two rotating shafts are symmetrical about the mid-vertical plane of the winding area, and the two drives operate synchronously, ensuring that the optical fiber can be wound evenly and smoothly on the optical fiber winding spool during the winding process, avoiding twisting, stretching or squeezing of the optical fiber due to inconsistent rotation speed or asymmetric position, thereby reducing the risk of damage to the optical fiber due to uneven force.

[0034] 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.
[0035] Example 1:
[0036] Combine Figure 1 , this embodiment 1 provides a winding shaft assembly for winding an optical fiber ring, comprising a base plate 11 and two support plates 12 arranged in parallel, the support plates 12 being arranged on the base plate 11; a gap between the two support plates 12 forming a winding area;
[0037] A driver 13 is provided on the support plate 12. The output end of the driver 13 is connected to a rotating shaft 18, which extends through the support column to the winding area. The two rotating shafts 18 are symmetrically arranged about the vertical plane of the winding area, and the two drivers 13 operate synchronously. The two rotating shafts 18 rotate in the same direction, achieving synchronization and preventing the optical fiber from being damaged or broken due to the asynchronous rotation of the two rotating shafts 18.
[0038] A follower disk 19 is sleeved on the rotating shaft 18. When the driver 13 drives the rotating shaft 18 to rotate, the rotating shaft 18 drives the follower disk 19 to rotate. One of the rotating shafts 18 is connected to an optical fiber winding shaft 20, which is used to receive the optical fiber.
[0039] The above-mentioned follower disk 19 and base plate 11 are used to connect the first optical fiber supply assembly 21 and the second optical fiber supply assembly 22. The first optical fiber supply assembly 21 and the second optical fiber supply assembly 22 are connected through a group of optical fibers. It is worth noting that the group of optical fibers here can be a single optical fiber or a fiber group composed of multiple optical fibers; the first optical fiber supply assembly 21 and the second optical fiber supply assembly 22 can both supply optical fibers to the optical fiber winding shaft 20, but do not supply optical fibers when connected to the follower disk 19, and only rotate with the follower disk 19.
[0040] A specific example for reference is as follows: the first optical fiber supply assembly 21 is the optical fiber fixing end, which is fixed on the follower disk 19; the second optical fiber supply assembly 22 is the optical fiber winding end, which is arranged on the base plate 11 and provides optical fiber to the optical fiber winding shaft 20; the above-mentioned rotating shaft 18 drives the optical fiber winding shaft 20 to rotate, and the first optical fiber supply assembly 21 rotates with the rotating shaft 18, and the optical fiber supplied by the second optical fiber supply assembly 22 is wound on the optical fiber winding shaft 20 as the optical fiber winding shaft 20 rotates.
[0041] The two rotating shafts 18 are symmetrical about the mid-vertical plane of the winding area, and the two drivers 13 operate synchronously, ensuring that the optical fiber can be evenly and smoothly wound on the optical fiber winding shaft 20 during the winding process, avoiding twisting, stretching or squeezing of the optical fiber due to inconsistent rotation speed or asymmetric position, thereby reducing the risk of damage to the optical fiber due to uneven force.
[0042] Before fiber winding, the first optical fiber supply assembly 21 is fixed on the corresponding follower disk 19, and then the driver 13 is started to start the fiber winding. The rotating shaft 18 and the follower disk 19 fixed on the rotating shaft 18 rotate synchronously to ensure that the optical fiber extending from the first optical fiber supply assembly 21 is protected from damage while the line is being wound. During the entire fiber winding process, the two rotating shafts 18 must be completely synchronized. Otherwise, when the first optical fiber supply assembly 21 is fixed on the follower disk 19 without the optical fiber winding shaft 20, the optical fiber will be stretched or broken due to the lack of synchronization between the two rotating shafts 18.
[0043] In a specific embodiment, the winding method of the optical fiber on the optical fiber winding shaft 20 is changed by switching the follower disk 19 for fixing the optical fiber.
[0044] A specific example for reference is used to wind an optical fiber ring using a winding shaft assembly. The structure of the winding shaft assembly is as follows: a follower disk 19 is connected to a rotating shaft 18 provided with an optical fiber winding shaft 20, and a follower disk 19 is connected to a rotating shaft 18 not provided with an optical fiber winding shaft 20. Drivers 13 and 13 respectively drive the rotating shaft 18 to rotate. The optical fibers of the first optical fiber supply assembly 21 and the second optical fiber supply assembly 22 are currently located at the leftmost side of the optical fiber winding shaft 20.
[0045] To achieve the winding method 1: before winding the fiber, the first optical fiber supply assembly 21 is fixed on the follower disk 19, and the second optical fiber supply assembly 22 is set on the bottom plate 11, as shown in FIG. Figure 2 As shown; fiber winding begins, the driver 13- and the driver 13-2 synchronously drive the rotating shaft 18 to rotate clockwise, and the optical fiber supplied by the second optical fiber supply assembly 22 is directly wound on the optical fiber winding shaft 20 in a counterclockwise direction. While supplying the optical fiber, the second optical fiber supply assembly 22 gradually moves away from the follower disk 19- (the device for moving the second optical fiber supply assembly 22 can use an electric slide rail, which is not limited to this device), so that the wiring direction is that the position where the optical fiber is wound on the optical fiber winding shaft 20 gradually moves away from the follower disk 19-;
[0046] To achieve the second winding method: before winding the fiber, the first optical fiber supply assembly 21 is fixed on the follower disk 192, and the second optical fiber supply assembly 22 is set on the bottom plate 11, as shown in FIG. Figure 3 As shown; fiber winding begins, driver 131 and driver 132 synchronously drive the rotating shaft 18 to rotate clockwise, and the optical fiber supplied by the second optical fiber supply component 22 counterclockwise covers the optical fiber extending from the first optical fiber supply component 21 and is wound on the optical fiber winding shaft 20. While supplying optical fiber, the second optical fiber supply component 22 gradually moves away from the follower disk 19- (the device for moving the second optical fiber supply component 22 can adopt an electric slide rail, and there is no limitation on the device), so that the wiring direction is that the position where the optical fiber is wound on the optical fiber winding shaft 20 gradually moves away from the follower disk 19-.
[0047] Example 2:
[0048] On the basis of Example 1, combined Figure 4 The follower disk 19 includes a first connection area 23, a second connection area 24 and an edge area 25. The first connection area 23 is arranged in the central area of the follower disk 19, the second connection area 24 is arranged around the first connection area 23, and the edge area 25 is arranged at the edge of the follower disk 19.
[0049] The first connection area 23 is used to connect to the rotating shaft 18; the second connection area 24 is used to connect to the first optical fiber supply assembly 21; the edge area 25 extends outward from the second connection area 24, and the thickness gradually decreases.
[0050] The above-mentioned first connection area 23 is arranged in the central area of the follower disk 19, and the rotating shaft 18 is connected to the first connection area 23, so that the follower disk 19 can rotate smoothly with the rotation of the rotating shaft 18; if the rotating shaft 18 is not connected to the central area of the follower disk 19, during the winding process, the distance between the follower disk 19 and the optical fiber winding shaft 20 is constantly changing, thereby causing the distance between the first optical fiber supply assembly 21 set on the follower disk 19 and the optical fiber winding shaft 20 to change constantly. Since the optical fiber extending from the first optical fiber supply assembly 21 is connected to the optical fiber winding shaft 20, when the distance between the first optical fiber supply assembly 21 and the optical fiber winding shaft 20 changes, the external force applied to the optical fiber extending from the first optical fiber supply assembly 21 changes, causing this part of the optical fiber to be stretched or broken; the edge area 25 is arranged at the edge of the follower disk 19, and the gradually decreasing thickness helps to reduce the weight of the follower disk 19, reduce the inertial force during rotation, and reduce the sudden change of optical fiber tension caused by inertia.
[0051] In a specific embodiment, the follower disk 19 may be rectangular or circular. When the follower disk 19 is rectangular, the edge of the follower disk 19 is curved.
[0052] The above-mentioned follower disk 19 may be affected by various factors and produce vibration or shaking during the rotation process. The curved edge design can better disperse and absorb vibration energy, reducing its impact on the optical fiber winding process; from the perspective of structural mechanics, the curved edge design can enhance the overall stability and rigidity of the follower disk 19, help reduce the deformation and vibration of the follower disk 19 during high-speed rotation, and ensure the accuracy and reliability of optical fiber winding.
[0053] Example 3:
[0054] Based on any of the above embodiments, the above-mentioned driver 13 includes a motor 14 (a servo motor may be used), a first synchronous pulley 15, a second synchronous pulley 17 and a synchronous belt 16. The output shaft of the above-mentioned motor 14 is connected to the first synchronous pulley 15, the above-mentioned second synchronous pulley 17 is connected to the rotating shaft 18, and the above-mentioned second synchronous pulley 17 is connected to the support plate 12 through a bearing; the above-mentioned first synchronous pulley 15 and the second synchronous pulley 17 are driven by the synchronous belt 16.
[0055] The motor 14 , the first synchronous pulley 15 , the synchronous belt 16 and the second synchronous pulley 17 cooperate to realize the transmission of the follower plate 19 ; the meshing transmission of the synchronous belt 16 ensures the smoothness of the transmission.
[0056] In a specific embodiment, the diameter of the first synchronous pulley 15 is smaller than the diameter of the second synchronous pulley 17 .
[0057] When the diameter of the above-mentioned first synchronous pulley 15 is smaller than the diameter of the second synchronous pulley 17, since the synchronous belt 16 is engaged with the teeth of the two synchronous belt 16 wheels, a reduction ratio will naturally be generated during the transmission process, which means that the output speed of the motor 14 will be higher than the speed of the rotating shaft 18, and the torque obtained by the rotating shaft 18 will increase accordingly; the design of the reduction ratio helps to adapt to different winding requirements, especially when a larger torque is required to drive the follower disk 19 and the optical fiber winding shaft 20; due to the reduction ratio in the transmission process, the output torque of the motor 14 will be amplified after being transmitted by the synchronous belt 16; because the optical fiber needs to overcome a certain resistance and friction during the winding process, especially when the optical fiber tension is large or the winding speed is high, the larger torque can ensure the smooth rotation of the follower disk 19 and the optical fiber winding shaft 20, and reduce slippage or vibration caused by insufficient torque.
[0058] 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. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
