Description

Technical Field

[0001] The utility model belongs to the technical field of optical fiber winding, and relates to an optical fiber coiling device. Background Art

[0002] An optical fiber is a slender fiber, usually made of glass or plastic, for transmitting optical signals. Optical fibers can be divided into various types according to their structures and applications. The most common ones are single-mode optical fibers and multi-mode optical fibers. Single-mode optical fibers have a smaller core diameter and are suitable for long-distance, high-speed communication scenarios, while multi-mode optical fibers have a larger core diameter and are suitable for short-distance, medium- and low-speed communication scenarios. An optical fiber coiling device is a device specifically used for managing and protecting optical fibers, which can ensure that the optical fibers maintain appropriate tension and curvature during storage or transmission, preventing the optical fibers from being damaged.

[0003] Common optical fiber coiling devices include one or more brackets for fixing optical fibers and a mechanism for guiding the coiling of optical fibers. The working principle is to achieve uniform coiling of optical fibers by rotating or moving the device. However, the existing devices for guiding the coiling of optical fibers are only used to guide the optical fibers to the winding shaft of the winding device in the way of a lead post, but this kind of guiding is usually to a fixed position of the winding shaft. For a winding shaft with a certain length, this method makes the optical fibers too concentrated on the winding shaft. In addition, the diameter of the winding roller of the existing winding device is fixed, so it is impossible to maintain uniform tension of the optical fibers during winding, resulting in reduced coiling efficiency and even possible damage to the optical fibers. Moreover, since different diameters of optical fibers require different tensions and spaces during coiling, the winding roller with a fixed diameter cannot provide the optimal coiling conditions for optical fibers with a specific diameter.

[0043] Compared with the prior art, the utility model provides an optical fiber coiling device, which has the following beneficial effects:

[0044] In the first aspect, for the optical fiber coiling device of the utility model, the moving device moves along the axial direction of the guiding shaft, so that the optical fiber is guided by the lead-in device and moves with the movement of the moving device to be wound around the winding shaft of the winding device. The rotation of the lead screw is converted into the linear movement of the lead screw nut by the lead screw nut, so as to realize the axial movement of the lead post along with the lead screw nut.

It can ensure that the optical fiber is subjected to appropriate tension during the coiling process, avoid the damage of the optical fiber caused by excessive tension, prolong the service life of the optical fiber, and enable the coiling device to adapt to optical fibers of different specifications and sizes, increasing the versatility and flexibility of the equipment. At the same time, the appropriate outer expansion diameter of the tensioning shaft helps to maintain the uniform tension of the optical fiber, so as to realize a more neat and tight coiling effect and improve the use quality of the coiling device.

[0079] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0080] As Figure 1 shown, an optical fiber coiling device includes a winding device 100 and a guiding device 200.

[0081] Among them, as Figure 1-6 shown, the winding device 100 includes a winding shaft 110, a third bracket 120, a second rotation driving device 140, a first limiting disk 150, a second limiting disk 160, and a card seat 170.

[0082] As Figure 1-2 shown, the second rotation driving device 140 is fixed on the third bracket 120. The first limiting disk 150 is connected to the second rotation driving device 140 and is used to drive the first limiting disk 150 to rotate. Preferably, the second rotation driving device 140 of the winding device 100 includes a first motor. The second limiting disk 160 and the first limiting disk 150 are oppositely arranged in the axial direction of the winding shaft 110. The card seat 170 and the third bracket 120 are oppositely arranged in the axial direction of the winding shaft 110. The card seat 170 is arranged below the second limiting disk 160, and the card seat 170 is provided with a slot 171 for accommodating and supporting the edge of the second limiting disk 160. Among them, the winding shaft 110 is arranged between the first limiting disk 150 and the second limiting disk 160. The first end of the winding shaft 110 is fixed in the central area of the first limiting disk 150, and the second end of the winding shaft 110 is fixed in the central area of the second limiting disk 160.

[0083] In the above solution, preferably, the winding device 100 further includes a fifth bracket 130. The fifth bracket 130 is installed at a certain height position on the third bracket 120, so that the height where the output shaft of the first motor is located is set at the same height as the position of the central region of the first limiting disc 150. The output shaft of the first motor is connected to the central region of the first limiting disc 150 and is fixed at a certain height by the third bracket 120 through the first motor, so that the output shaft of the first motor connects to the first limiting disc 150 and supports it at a certain height. Among them, the function of the third bracket 120 is to support the first motor at a certain height. However, it can be understood that the third bracket 120 has no fixed relationship with the output shaft of the first motor and the first limiting disc 150. Therefore, the output shaft of the first motor can fix the first limiting disc 150 at a certain height and drive it to rotate.

[0084] In the above solution, the first limiting disc 150 is fixed to the second limiting disc 160 through the winding shaft 110, especially fixed to the front cylinder wall 161 of the second limiting disc 160, so that the second limiting disc 160 can rotate with the first limiting disc 150 through the fixation of the winding shaft 110, realizing the function of winding.

[0085] In the above solution, through the winding shaft 110, the first limiting disc 150 connects and fixes the second limiting disc 160 at a certain height. In order to further stabilize the height position of the fixed second limiting disc 160 and make it more stable, the second limiting disc 160 is further supported by the card seat 170. As Figure 6 shown, in a preferred solution, the winding device 100 further includes a cylindrical roller 172. The cylindrical roller 172 is arranged at intervals between two opposite groove walls of the card slot 171 along the axial direction of the slot. The cylindrical roller 172 is preferably a rubber roller, which can improve the smoothness of the rotation of the second limiting disc 160.

[0086] As Figures 3-5As shown, a plurality of first expansion and contraction curve through holes 1611 that are bent toward the first clockwise direction are provided on the front cylinder wall 161 of the second limiting disk 160. The winding device 100 further includes an expansion and contraction mechanism, and the expansion and contraction mechanism includes a rotating disk 163, a third rotation driving device 164, an assembly disk 165, and a tensioning shaft 166. The rotating disk 163 is disposed in the space inside the second limiting disk 160, and a plurality of second expansion and contraction curve through holes 1631 that are bent toward the second clockwise direction are provided on the rotating disk 163. The third rotation driving device 164 is connected to the rotating disk 163 and is configured to drive the rotating disk 163 to rotate. Preferably, the third rotation driving device 164 includes a second motor. Insertion rods 1651 and limiting rods 1652 are provided on the assembly disk 165. The insertion rods 1651 penetrate and are limited in the first expansion and contraction curve through holes 1611 of the front cylinder wall 161 and the second expansion and contraction curve through holes 1631 of the rotating disk 163, and the limiting rods 1652 penetrate and are limited in the first expansion and contraction curve through holes 1611 of the front cylinder wall 161. The tensioning shaft 166 includes a first end and a second end. The first end is fixed to the assembly disk 165, and there is a gap between the second end and the first limiting disk 150. Among them, the first expansion and contraction curve through holes 1611 and the second expansion and contraction curve through holes 1631 are disposed opposite to each other, and the first clockwise direction and the second clockwise direction are opposite clockwise directions.

[0087] In the above solution, it can be understood that there is a gap between the second end of the tensioning shaft 166 and the first limiting disk 150, that is, the tensioning shaft 166 is only connected to the assembly disk 165 and is connected to the front cylinder wall 161 of the second limiting disk 160 through the assembly disk 165. However, the tensioning shaft is not connected to the first limiting disk 150 but is separated from the first limiting disk 150. Of course, it may also be in contact. Therefore, the movement of the tensioning shaft 166 will not cause the first limiting disk 150 to move followingly.

[0088] In the above solution, the second limiting disk 160 is arranged as a hollow structure. It can be understood that the rotating disk 163 is placed in the internal space of the second limiting disk 160. However, the rotating disk 163 has no fixed connection relationship with the inner part of the shell of the second limiting disk 160, such as the cylinder wall. The rotating disk 163 is separated from the shell of the second limiting disk 160 and is only arranged in the hollow of the shell of the second limiting disk 160. For the realization of the above purpose, in a preferred solution, the optical fiber coiling device further includes a fourth bracket 168. The shell of the second motor of the third rotation driving device 164 is arranged on the fourth bracket 168. The fourth bracket 168 supports the shell of the second motor, so that the height of the output shaft of the second motor is set at the same height as the position on the rotating disk 163 that is connected to the output shaft of the second motor. The rotating disk 163 arranged in the internal space of the second limiting disk 160 is connected and supported by the output shaft of the second motor. The second limiting disk 160 is provided with a through hole through which the output shaft of the second motor passes on its rear cylinder wall 162. The output shaft of the second motor passes through the through hole and is fixed to the rotating disk 163, and there is a certain gap between the output shaft of the second motor and the through hole, so that the output shaft of the second motor is not connected to the second limiting disk 160.

[0089] This shows that the second motor only passes through the through hole in the rear cylinder wall 162 of the second limiting disk 160 but is not connected to the hole wall of the through hole, and the rotating disk 163 is connected and supported by the output shaft of the second motor. As described above, the second limiting disk 160 is supported by the shell of the second limiting disk 160 through the fixing of the first motor rotating shaft passing through the first limiting disk 150 and the winding shaft 110, and further supported by the clamping seat 170 for the shell of the second limiting disk 160. It can be seen that the shell of the second limiting disk 160 and the rotating disk 163 arranged in the shell of the second limiting disk 160 are driven to rotate by different driving structures, and they are in a separated relationship. Only the rotating disk 163 is connected and supported by the output shaft of the second motor in the hollow of the shell of the second limiting disk 160.

[0090] Thus, it can be seen that when the tensioning shaft 166 expands and contracts due to the rotation of the rotating disk 163 driven by the second motor, it will not cause the shell of the second limiting disk 160 to rotate. When the first motor drives the first limiting disk 150 to rotate and transmits the rotation to the shell of the second limiting disk 160 through the winding shaft 110, it will not cause the rotating disk 163 to rotate accordingly.

[0091] The first clockwise direction is counterclockwise, and the second clockwise direction is clockwise. Of course, it can also be defined conversely. It can be seen that the second limiting disk 160 is provided with a plurality of first expansion and contraction curve through holes 1611 that are bent in the counterclockwise direction on its front cylinder wall 161, and the rotating disk 163 is provided with a plurality of second expansion and contraction curve through holes 1631 that are bent in the clockwise direction.

[0092] As Figure 3 shown, it shows three of the tension shafts 166. Figure 3 In the upper left of it, the second expansion and contraction curve through hole 1631 that is bent in the clockwise direction of the rotating disk 163 is schematically shown. Figure 3 In the upper right of it, the first expansion and contraction curve through hole 1611 that is bent in the counterclockwise direction of the front cylinder wall 161 of the second limiting disk 160 is schematically shown. Figure 3 In the lower part of it, a set of cooperating first expansion and contraction curve through holes 1611 that are bent in the counterclockwise direction of the front cylinder wall 161 of the second limiting disk 160 and the second expansion and contraction curve through holes 1631 that are bent in the clockwise direction of the rotating disk 163 are completely schematically shown. It can be seen that a set of cooperating expansion and contraction curve through holes are two long strip-shaped arc holes with opposite bending directions. The bending direction refers to the orientation in which the central part of the long strip hole protrudes outward. It can be found that a set of expansion and contraction curve through holes are a set of mirror holes. When the limiting rod 1652 reaches the end position of the expansion and contraction curve through hole, the holes at the end position coincide and correspond.

[0093] The expansion and contraction are realized in the following way: The rotating disk 163 of the winding device 100 is driven by the second motor to rotate in the counterclockwise direction, so that the outer hole wall of the second expansion and contraction curve through hole 1631 that is bent in the clockwise direction of the rotating disk 163 presses the plug rod 1651. Thus, under the guiding action of the first expansion and contraction curve through hole 1611 that is bent in the counterclockwise direction on the front cylinder wall 161, the plug rod 1651 and the limiting rod 1652 move along the first expansion and contraction curve through hole 1611 of the front cylinder wall 161 towards the center direction to contract the distance between the tension shafts 166.

[0094] The rotating disk 163 of the winding device 100 is driven by the second motor to rotate in the clockwise direction, so that the inner hole wall of the second expansion and contraction curve through hole 1631 that is bent in the clockwise direction of the rotating disk 163 presses the plug rod 1651. Thus, under the guiding action of the first expansion and contraction curve through hole 1611 that is bent in the counterclockwise direction on the front cylinder wall 161, the plug rod 1651 and the limiting rod 1652 move along the first expansion and contraction curve through hole 1611 of the front cylinder wall 161 towards the circumferential direction to expand the distance between the tension shafts 166.

[0095] In one solution, as Figure 4 shown, the expansion and contraction mechanism further includes a first nut 167, which is in threaded fit with the front end of the first end of the insertion rod 1651, and limits the rotating disk 163 and the front cylinder wall 161 between the first nut 167 and the assembly disk 165. The above solution is used to enable the insertion rod 1651 to be stably limited between a set of first expansion and contraction curve through holes 1611 and second expansion and contraction curve through holes 1631.

[0096] In the above solution, when necessary, the rotation of the winding shaft 110 can be stopped first, and the expansion and contraction can be carried out first, and then the winding shaft 110 can be rotated after the expansion and contraction. Since the diameter of the winding shaft 110 can be expanded and contracted, it can ensure that the optical fiber is subjected to appropriate tension during the winding process, avoid optical fiber damage caused by excessive tension, extend the service life of the optical fiber, and enable the winding device to adapt to optical fibers of different specifications and sizes, increasing the versatility and flexibility of the equipment. At the same time, the appropriate outer expansion diameter of the tensioning shaft 166 helps to maintain the uniform tension of the optical fiber, thereby achieving a more neat and tight winding effect and improving the use quality of the winding device.

[0097] As Figure 1 and 7 shown, the guiding device 200 includes a guiding shaft 210 and a moving device 220. The moving device 220 includes a wire guiding device. The winding shaft 110 of the winding device 100 and the guiding shaft 210 of the guiding device 200 are arranged relatively parallel in the axial direction. Among them, the moving device 220 moves along the axial direction of the guiding shaft 210, so that the optical fiber is guided by the wire guiding device and moves with the movement of the moving device 220 and winds around the winding shaft 110 of the winding device 100.

[0098] The guiding shaft 210 of the guiding device 200 includes a lead screw. The moving device 220 includes a lead screw nut. The wire guiding device includes a wire guiding post 230. The guiding device 200 further includes a first bracket 240, a first bearing, a second bracket 250, a second bearing, a bottom rod 260, a guide rail 270 and a first rotation driving device 280.

[0099] The outer ring of the first bearing is fixed to the first bracket 240. The second bracket 250 is disposed opposite to the first bracket 240 in the axial direction of the guide shaft 210. The outer ring of the second bearing is fixed to the second bracket 250. The bottom rod 260 is disposed at the lower end of the lead screw nut, and the lower end of the bottom rod 260 is formed into a limiting portion 261. The guide rail 270 is disposed between the first bracket 240 and the second bracket 250. The guide rail 270 includes a guide rail groove 271, and the limiting portion 261 of the bottom rod 260 is limited in the guide rail groove 271. The first rotation driving device 280 is connected to the lead screw for driving the lead screw to rotate. Among them, the lead screw is disposed between the first bearing on the first bracket 240 and the second bearing on the second bracket 250. The first end of the lead screw is disposed in the inner ring of the first bearing, and the second end of the lead screw is disposed in the inner ring of the second bearing. In the above manner, the lead post 230 provided on the moving device 220 can move along the axial direction, so that the movement in this axial direction can guide the optical fiber to realize the automation of winding at different positions on the winding shaft 110.

[0100] The first rotation driving device 280 of the guiding device 200 includes a belt transmission device. The belt transmission device includes a driving pulley 281, a driven pulley 282, and a transmission belt 283 disposed between the driving pulley 281 and the driven pulley 282. The driven pulley 282 is connected to the first end of the lead screw. The driving pulley 281 is connected to the output shaft of the first motor. In the above solution, the output shaft of the first motor, that is, the motor rotating shaft, is connected to the first limiting disc 150 through the driving pulley 281, connected to the driven pulley 282 through belt transmission, and connected to the guide shaft 210 through the driven pulley 282, so that the first motor can synchronously drive the first limiting disc 150 and the guide shaft 210, which can improve the synchronism of wire guiding and winding. Of course, the first rotation driving device 280 can be replaced by a motor for step-by-step winding and guiding.

[0101] The guiding device 200 conducts guiding based on the following method: The lead screw of the guiding shaft 210 rotates under the drive of the first rotation driving device 280. The lead nut is arranged on the lead screw, and the bottom rod 260 at the lower end of the lead nut is limited in the guide groove 271 of the guide rail 270, so that the lead nut cannot rotate with the lead screw. However, as the lead screw rotates, due to the effect of the thread, the lead nut converts the rotation of the lead screw into the linear movement of the lead nut, thereby enabling the lead post 230 to move axially along with the lead nut. For a winding shaft 110 with a certain length, this method avoids the concentrated distribution of the optical fiber on the winding shaft 110. That is, the above solution enables the optical fiber to be evenly wound, avoids the phenomenon of concentrated winding and intersection, and improves the practicability of the device.

[0102] In the first aspect, for the optical fiber coiling device of the present utility model, the moving device 220 moves along the axial direction of the guiding shaft 210, so that the optical fiber is guided by the guiding device and moves and winds around the winding shaft 110 of the winding device 100 along with the movement of the moving device 220. The lead nut converts the rotation of the lead screw into the linear movement of the lead nut, thereby enabling the lead post 230 to move axially along with the lead nut. For a winding shaft 110 with a certain length, this method avoids the concentrated distribution of the optical fiber on the winding shaft 110, enables the optical fiber to be evenly wound, avoids the phenomenon of concentrated winding and intersection, and improves the practicability of the device.

[0103] In the second aspect, for the optical fiber coiling device of the present utility model, the first motor drives the rotation of the main pulley, so that the second limiting disk 160 can be driven to rotate under the driving action of the first limiting disk 150 and the winding shaft 110 to realize winding. The second motor drives the rotation of the rotating disk 163, so that the tensioning shaft 166 can be driven to synchronously expand and contract under the cooperation of the expansion and contraction curve through holes, and further the diameter size between the tensioning shafts 166 can be adjusted. It can ensure that the optical fiber is subjected to appropriate tension during the coiling process, avoid damage to the optical fiber caused by excessive tension, extend the service life of the optical fiber, and enable the coiling device to adapt to optical fibers of different specifications and sizes, increasing the versatility and flexibility of the equipment. At the same time, the appropriate outer expansion diameter of the tensioning shaft 166 helps to maintain the uniform tension of the optical fiber, thereby realizing a more neat and tight coiling effect and improving the use quality of the coiling device.
