Description

Technical Field

[0001] This invention relates to the field of optical fiber winding, and more specifically to a mesh-like multi-core optical fiber winding device. Background Technology

[0002] Mesh multicore optical fiber is a special type of optical fiber in which multiple fiber cores are arranged irregularly, in a mesh or random manner within the cross-section of the fiber in the same cladding. Fiber winding refers to the process of tightly and regularly winding a section of optical fiber together according to a specific diameter and number of turns, and then securing it with cable ties or directly winding it onto a cylindrical winding spool.

[0003] After searching, some existing technologies were found, which will be introduced one by one:

[0004] Firstly, Chinese utility model patent with authorization announcement number CN223547466U discloses a cable winding machine that uses a motor to provide power for the rotation of the winding drum to achieve the purpose of cable winding.

[0005] Secondly, Chinese utility model patent with authorization announcement number CN212049921U discloses a household cable winding auxiliary tool, which drives the winding shaft to rotate through the rotating shaft of the winding machine to achieve the purpose of cable winding.

[0006] Both of the aforementioned existing patent documents achieve cable winding by driving the winding spool or winding drum to rotate. Both the winding spool and winding drum are cylindrical. After winding, when the cable is removed from the winding spool, the innermost layer of cable contacts the spool. To ensure the quality of the winding result—that is, to ensure tight and regular winding—the cable is tightly wound during the winding process. This results in significant friction between the innermost layer of cable and the winding spool. On one hand, this friction increases the difficulty of removing the cable from the winding spool; on the other hand, the significant friction can easily cause wear on the outer sheath of the innermost layer of cable. Although this does not affect quality, it can affect customer purchasing desire. Furthermore, inexperienced workers may forcibly pull the cable off, causing the innermost layer of cable to loosen and affecting the winding quality.

[0007] Based on the above, the present invention proposes a mesh-like multi-core optical fiber winding device. Summary of the Invention

[0008] To address the problems mentioned in the background above, the present invention provides a mesh-like multi-core optical fiber winding device.

[0009] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0010] A mesh multi-core optical fiber winding device includes a frame, on which a winding component and a feeding component are arranged. The winding component includes a winding assembly, a first linear module, and a driving component. The first linear module is used to move the two winding assemblies closer to each other or further away from each other. The driving component is used to provide power for the operation of the winding assembly.

[0011] The winding assembly includes a movable bracket. Each of the two movable brackets of the two winding assemblies has a rotating shaft on one side facing each other. The two rotating shafts are arranged coaxially. A winding shaft is coaxially provided at one end of each rotating shaft facing each other. A side disc is coaxially provided at one end of each winding shaft facing away from each other.

[0012] The rotating shaft is hollow and has a clearance opening on its outer surface. The guiding direction of the clearance opening is parallel to the axis of the rotating shaft.

[0013] A second lead screw is coaxially located inside the rotating shaft, and the input end of the second lead screw extends out of the rotating shaft and is connected to the movable bracket.

[0014] A movable disc is sleeved on the outside of the rotating shaft. A support body is provided on the inner ring surface of the movable disc. After passing through the clearance opening, the support body is threadedly connected to the second lead screw. The support body and the clearance opening form a sliding guide fit.

[0015] A limiting protrusion is provided on the side of the movable disc facing the winding shaft, and the limiting protrusion is made of elastic material.

[0016] Furthermore, initially, the limiting protrusion passes through the through-hole set on the side disc and is located outside the winding shaft, and the distance between the limiting protrusion and the outer circular surface of the winding shaft is less than the diameter of the optical fiber cable.

[0017] Furthermore, the first linear module includes a first lead screw and a first linear guide arranged horizontally and parallel to each other, with the first lead screw parallel to the rotation axis;

[0018] The movable bracket is slidably connected to the first linear rail. The input end of the first lead screw is powered by the first motor. The first lead screw is divided into two threaded segments with opposite thread directions along its own axis. The two movable brackets are threadedly connected to the two threaded segments respectively.

[0019] Furthermore, the drive assembly includes a first transmission shaft and a second transmission shaft parallel to the first lead screw. The input end of the first transmission shaft is powered by a second motor, and the input end of the second transmission shaft is powered by a third motor.

[0020] Furthermore, a second power transmission component is provided between the rotating shaft and the second transmission shaft to realize the power connection between the two. The driving component of the second power transmission component is connected to the second transmission shaft through the second connecting component. When the movable bracket moves together with the driving component of the second power transmission component, the second transmission shaft continuously outputs power to the driving component of the second power transmission component through the second connecting component. The second connecting component includes an inner spline two provided on the driving component of the second power transmission component and an outer spline two provided on the second transmission shaft.

[0021] Furthermore, a first power transmission component is provided between the second lead screw and the first transmission shaft to realize the power connection between the two. The driving component of the first power transmission component is connected to the first transmission shaft through the first connector. When the movable bracket moves together with the driving component of the first power transmission component, the first transmission shaft continuously outputs power to the driving component of the first power transmission component through the first connector. The first connector includes an internal spline on the driving component of the first power transmission component and an external spline on the first transmission shaft.

[0022] Furthermore, the outer circular surface of the winding shaft is provided with a first clearance groove, which extends to both ends of the winding shaft, and the outer circular surface of the side disk is provided with a second clearance groove, which extends to both ends of the side disk. The first clearance groove and the second clearance groove are connected.

[0023] Furthermore, the winding shaft is shaped like a frustum, and the outer diameter of the winding shaft decreases along the axis and from the side disk toward the end of the winding shaft.

[0024] Furthermore, the feeding assembly includes a third lead screw and a second linear guide parallel to the rotation axis. A transverse slide is slidably mounted on the second linear guide, and the transverse slide and the third lead screw form a threaded connection. A fourth motor is poweredly connected to the input end of the third lead screw.

[0025] A vertically arranged guide rod is provided on the upper surface of the horizontal slide block. A vertical slide block is slidably installed on the outside of the guide rod. A fixing ring is provided at the upper end of the guide rod. A spring is sleeved on the outside of the guide rod between the vertical slide block and the fixing ring.

[0026] A feed hole is provided through the side of the vertical slide facing the winding component, and a feed pipe is coaxially provided at the opening of the feed hole.

[0027] Furthermore, the distance between the centerline of the feeding pipe and the centerline of the winding shaft is equal to the sum of the outer radius of the winding shaft and the inner radius of the feeding pipe.

[0028] Compared with the prior art, the beneficial effects of this invention are as follows:

[0029] This case presents a high-efficiency, damage-resistant cable winding technology solution based on a separable limiting protrusion made of elastic material. Furthermore:

[0030] Technical effect 1: When the second layer of the optical fiber cable is fully wound, the movable disk moves backward along with the limiting protrusion, ensuring the tightness of the subsequent optical fiber cable winding. Furthermore, both movable disks are equipped with limiting protrusions, so when winding the optical fiber cable, you can start from one end of the winding shaft or from the other end of the winding shaft, which can improve the winding efficiency.

[0031] Technical effect 2: This invention uses a flexible limiting protrusion that can be manually lifted and deformed upwards to insert the cable end between the limiting protrusion and the winding shaft. It can compress cables of any diameter and has a wider range of applications.

[0032] Technical Effect 3: In this case, the optical fiber cable is wound around the winding spool in layers. The innermost layer of optical fiber cable has a relatively tight contact with the winding spool, resulting in a large contact force. Therefore, before discharge, there is a large static friction between the innermost layer of optical fiber cable and the winding spool. During discharge, as the two winding spools move away from each other, there will be a relative displacement between the two winding spools and the innermost layer of optical fiber cable. Since the two winding spools are truncated cone-shaped, as long as there is a slight relative displacement between the two winding spools and the innermost layer of optical fiber cable, the contact force between the innermost layer of optical fiber cable and the winding spool will be greatly reduced. The optical fiber cable will be able to quickly fall off the winding spool and fall through the gap formed after the two winding spools move away from each other.

[0033] Technical Effect 4: Building upon Technical Effect 3, an unexpected situation may occur: when the two winding spools move away from each other, the innermost fiber optic cable undergoes relative displacement with one of the winding spools, but not or only slightly with the other. In other words, the fiber optic cable roll does not detach from the two winding spools as they move away; instead, it remains attached to one of the winding spools due to static friction. In this case, the moving disc advances, carrying the limiting protrusion along with it. The limiting protrusion pushes the fiber optic cable roll off the winding spool. Specifically, the length of the limiting protrusion is equal to half the length of the fiber optic cable roll, for example, 15-25cm. During winding, the limiting protrusion extends a short distance into the winding spool, approximately the outer diameter of the fiber optic cable, just enough to clamp the end of the cable. When assisting the fiber optic cable roll to leave the winding spool, it extends as far as possible, working in conjunction with the truncated cone of the winding spool to quickly push the fiber optic cable roll off and fall through the gap formed after the two winding spools move away from each other.

[0044] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0045] In the attached diagram of this solution, a refers to the fiber optic cable after the fiber winding is completed, and b refers to the cable tie.

[0046] Reference Figures 1-8 A mesh multi-core optical fiber winding device includes a frame 100, on which a winding component 200, a feeding component 300, and a guide plate 101 are provided. The winding component 200 and the feeding component 300 cooperate to achieve the purpose of winding optical fiber cables. The guide plate 101 is used to guide the optical fiber cables after winding to leave.

[0047] Winding component 200:

[0048] Reference Figures 5-8 The winding component 200 includes a winding assembly, a first linear module, and a drive assembly. Two winding assemblies are arranged side by side. The first linear module is used to move the two winding assemblies closer to each other or further away from each other. The drive assembly is used to provide power for the operation of the winding assembly.

[0049] Furthermore, refer to Figure 5 The winding assembly includes a movable bracket 207. The first linear module includes a first lead screw 202 and a first linear rail arranged horizontally and parallel to each other. The movable bracket 207 and the first linear rail are slidably connected. The input end of the first lead screw 202 is powered by a first motor 201. The first lead screw 202 is divided into two threaded segments with opposite thread directions along its own axis. The two movable brackets 207 are threadedly connected to the two threaded segments respectively. Therefore, when the first lead screw 202 is driven to rotate by the first motor 201, the two movable brackets 207 move closer to each other or further away from each other, thereby achieving the purpose of driving the two winding assemblies to move closer to each other or further away from each other.

[0050] Furthermore, refer to Figure 5 The drive assembly includes a first transmission shaft 204 and a second transmission shaft 206 parallel to the first lead screw 202. The input end of the first transmission shaft 204 is powered by a second motor 203, and the input end of the second transmission shaft 206 is powered by a third motor 205.

[0051] Furthermore, refer to Figure 6 and Figure 7 Each of the two movable supports 207 of the winding assembly is provided with a rotating shaft 208 on the opposite side. The two rotating shafts 208 are arranged coaxially and are parallel to the first lead screw 202.

[0052] Two rotating shafts 208 are coaxially mounted with a winding shaft 210 at their opposite ends, and a side disc 211 is coaxially mounted at their opposite ends.

[0053] The rotating shaft 208 is hollow and has a clearance opening 209 on its outer surface. The guiding direction of the clearance opening 209 is parallel to the axis of the rotating shaft 208.

[0054] A second lead screw 213 is coaxially located inside the rotating shaft 208. The input end of the second lead screw 213 extends out of the rotating shaft 208 and is connected to the movable bracket 207.

[0055] A movable disk 212 is sleeved on the outside of the rotating shaft 208. A support body is provided on the inner ring surface of the movable disk 212. The support body passes through the clearance opening 209 and is threadedly connected to the second lead screw 213. The support body and the clearance opening 209 form a sliding guide fit. Therefore, when the second lead screw 213 rotates, it can drive the support body and the movable disk 212 to move on the rotating shaft 208. In addition, it should be noted that when the rotating shaft 208 rotates, it will take the movable disk 212 and the support body with it to rotate. Since the movable disk 212 will move axially while rotating, if it is necessary for the movable disk 212 to not move axially, then the second lead screw 213 needs to rotate at the same time to drive the movable disk 212 to move in the opposite direction to counteract the axial movement generated during rotation.

[0056] Furthermore, a second power transmission component is provided between the rotating shaft 208 and the second transmission shaft 206 to realize the power connection between the two. The driving component of the second power transmission component is connected to the second transmission shaft 206 through the second connector. When the movable bracket 207 moves together with the driving component of the second power transmission component, the second transmission shaft 206 continuously outputs power to the driving component of the second power transmission component through the second connector. Preferably, the second connector includes an inner spline two provided on the driving component of the second power transmission component and an outer spline two provided on the second transmission shaft 206.

[0057] Furthermore, a first power transmission component is provided between the second lead screw 213 and the first transmission shaft 204 to realize the power connection between the two. The driving component of the first power transmission component is connected to the first transmission shaft 204 through the first connector. When the movable bracket 207 moves together with the driving component of the first power transmission component, the first transmission shaft 204 continuously outputs power to the driving component of the first power transmission component through the first connector. Preferably, the first connector includes an internal spline provided on the driving component of the first power transmission component and an external spline provided on the first transmission shaft 204.

[0058] Reference Figure 7 The outer circumferential surface of the winding shaft 210 is provided with a first clearance groove 214, which extends to both ends of the winding shaft 210. Similarly, the outer circumferential surface of the side disc 211 is provided with a second clearance groove 215, which also extends to both ends of the side disc 211. The first clearance groove 214 and the second clearance groove 215 are connected. The purpose of providing the first clearance groove 214 and the second clearance groove 215 is to... (The sentence is incomplete and requires further context to translate accurately.) Figure 2 After the fiber optic cable is wound, the cable tie can be passed through the first clearance slot 214 and the second clearance slot 215, that is, through the innermost fiber optic cable, and then the fiber optic cable can be tied, which is more convenient.

[0059] Reference Figure 8The winding shaft 210 is shaped like a frustum, and its outer diameter decreases along the axis and from the side disc 211 towards the end of the winding shaft 210. It should be noted that the inclination angle of the generatrix of the frustum is small, for example, 5-10 degrees. Its technical advantage is that after the fiber optic cable is wound and tied with a cable tie, when the two winding shafts 210 move away from each other to remove the fiber optic cable, a little force is required at first. However, since the winding shafts 210 are set in a frustum shape and the two winding shafts 210 are symmetrically distributed, the innermost fiber optic cable only makes simple contact with the winding shaft 210 without tight contact, and the friction is very small. Therefore, the difficulty of removing the fiber optic cable is greatly reduced and damage to the fiber optic cable is avoided.

[0060] Reference Figure 7 A limiting protrusion 216 is provided on the side of the movable disk 212 facing the winding shaft 210. The limiting protrusion 216 is made of an elastic material, such as rubber or silicone. Initially, the limiting protrusion 216 passes through the through hole provided on the side disk 211 and is located outside the winding shaft 210. The distance between the limiting protrusion 216 and the outer circular surface of the winding shaft 210 is less than the diameter of the optical fiber cable. The end of the optical fiber cable can be inserted between the limiting protrusion 216 and the outer circular surface of the winding shaft 210, and the optical fiber cable can be clamped by the two. After the optical fiber cable has completed two layers of winding, the movable disk 212 can be retracted to pull out the limiting protrusion 216.

[0061] Feeding assembly 300:

[0062] Reference Figures 1-4 The feeding assembly 300 includes a third lead screw 302 parallel to the first lead screw 202 and a second linear guide. A transverse slide 303 is slidably mounted on the second linear guide, and the transverse slide 303 and the third lead screw 302 are threadedly connected. The input end of the third lead screw 302 is poweredly connected to a fourth motor 301. Therefore, the fourth motor 301 drives the third lead screw 302 to rotate, thereby driving the transverse slide 303 to move on the second linear guide.

[0063] A vertically arranged guide rod 304 is provided on the upper surface of the horizontal slide block 303. A vertical slide block 305 is slidably installed on the outside of the guide rod 304. A fixing ring 306 is provided at the upper end of the guide rod 304. A spring 307 is sleeved on the outside of the guide rod 304 between the vertical slide block 305 and the fixing ring 306.

[0064] A feed hole is provided through the side of the vertical slide 305 facing the winding member 200. A feed pipe 308 is coaxially provided at the opening of the feed hole. Furthermore, the distance between the center line of the feed pipe 308 and the center line of the winding shaft 210 is equal to the sum of the outer radius of the winding shaft 210 and the inner radius of the feed pipe 308.

[0065] Preferably, when winding the optical fiber cable, the optical fiber cable can be pulled and wound onto the winding shaft 210 by the rotation of the winding shaft 210. Alternatively, a traction member can be provided on the vertical slide 305 to pull the optical fiber cable towards the winding shaft 210, assisting in the winding of the optical fiber cable and making the winding process smoother. The traction member can be implemented using existing technology, such as driving two traction wheels to rotate by a motor. The optical fiber cable passes through the area between the two traction wheels, and the rotation of the traction wheels can pull the optical fiber cable to move.

[0066] Reference Figures 1-3 The guide plate 101 is arranged at an angle and is located below the winding shaft 210.

[0067] Working principle of the invention:

[0068] First, insert the end of the optical fiber cable between the limiting protrusion 216 and the outer circular surface of the winding shaft 210, and the optical fiber cable can be clamped by the two.

[0069] The rotating shaft 208 rotates the winding shaft 210, and at the same time, the horizontal slide 303 reciprocates along the axis of the winding shaft 210. The two work together to orderly wind the optical fiber cable around the outside of the winding shaft 210.

[0070] During the fiber winding process, after the optical fiber cable has completed two layers of winding, the movable disc 212 retracts and pulls out the limiting protrusion 216.

[0071] After the fiber winding is completed, the movable reel 212 moves away from the winding shaft 210. The staff can use cable ties to bind the fiber optic cable by cooperating with the first clearance groove 214 and the second clearance groove 215.

[0072] After binding is completed, the two winding spools 210 move away from each other, causing the optical fiber cable to leave the winding spools 210 and fall into the guide plate 101, where it is guided out by the guide plate 101.

[0073] Its technological advantages lie in:

[0074] This case presents a high-efficiency, damage-resistant cable winding technology solution based on a separable limiting protrusion made of elastic material. Furthermore:

[0075] Technical effect 1: When the second layer of the optical fiber cable is fully wound, the movable disk moves backward along with the limiting protrusion, ensuring the tightness of the subsequent optical fiber cable winding. Furthermore, both movable disks are equipped with limiting protrusions, so when winding the optical fiber cable, you can start from one end of the winding shaft or from the other end of the winding shaft, which can improve the winding efficiency.

[0076] Technical effect 2: This invention uses a flexible limiting protrusion that can be manually lifted and deformed upwards to insert the cable end between the limiting protrusion and the winding shaft. It can compress cables of any diameter and has a wider range of applications.

[0077] Technical Effect 3: In this case, the optical fiber cable is wound around the winding spool in layers. The innermost layer of optical fiber cable has a relatively tight contact with the winding spool, resulting in a large contact force. Therefore, before discharge, there is a large static friction between the innermost layer of optical fiber cable and the winding spool. During discharge, as the two winding spools move away from each other, there will be a relative displacement between the two winding spools and the innermost layer of optical fiber cable. Since the two winding spools are truncated cone-shaped, as long as there is a slight relative displacement between the two winding spools and the innermost layer of optical fiber cable, the contact force between the innermost layer of optical fiber cable and the winding spool will be greatly reduced. The optical fiber cable will be able to quickly fall off the winding spool and fall through the gap formed after the two winding spools move away from each other.

[0078] Technical Effect 4: Building upon Technical Effect 3, an unexpected situation may occur: when the two winding spools move away from each other, the innermost fiber optic cable undergoes relative displacement with one of the winding spools, but not or only slightly with the other. In other words, the fiber optic cable roll does not detach from the two winding spools as they move away; instead, it remains attached to one of the winding spools due to static friction. In this case, the moving disc advances, carrying the limiting protrusion along with it. The limiting protrusion pushes the fiber optic cable roll off the winding spool. Specifically, the length of the limiting protrusion is equal to half the length of the fiber optic cable roll, for example, 15-25cm. During winding, the limiting protrusion extends a short distance into the winding spool, approximately the outer diameter of the fiber optic cable, just enough to clamp the end of the cable. When assisting the fiber optic cable roll to leave the winding spool, it extends as far as possible, working in conjunction with the truncated cone of the winding spool to quickly push the fiber optic cable roll off and fall through the gap formed after the two winding spools move away from each other.
