Of course, they are only examples, and the purpose is not to limit the present application.

[0033] The embodiments of the present application provide a fiber placing device and a fiber tray equipment. The following are described in detail respectively.
[0034] First, the embodiments of the present application provide a fiber placing device.
[0035] Figure 1 Structural schematic diagram of one embodiment of the fiber placing device provided by the embodiment of the present application. Figure 2 Structural schematic diagram of one embodiment of the fiber placing device provided by the embodiment of the present application. As shown in Figure 1, the fiber placing device comprises a fiber placing wheel 31, a mounting frame 32, a traction assembly 33, a guide assembly 34, and a crimping mechanism 332. Figure 1 and Figure 2As shown, the fiber unwinding device 30 comprises a mounting frame 32, a fiber unwinding wheel 31, a traction assembly 33 and a guide assembly 34. The fiber unwinding wheel 31 is connected with the mounting frame 32, and is used to rotate and support the fiber disc 40. The traction assembly 33 is installed on the mounting frame 32, and is used to connect with the coiled fiber of the fiber disc 40 and pull the fiber so that the fiber disc 40 unwinds. The guide assembly 34 is installed on the mounting frame 32, and is used to abut against the fiber between the fiber disc 40 and the traction assembly 33 to guide the fiber so that the coiled fiber of the fiber disc 40 can be stably transmitted to the traction assembly 33.
[0036] In some embodiments, as shown in Figure 3 and Figure 4 The guide assembly 34 can comprise a supporting shaft 341 and a guide wheel 342. The supporting shaft 341 is connected with the mounting frame 32, and the axial direction of the supporting shaft 341 is consistent with the axial direction of the fiber unwinding wheel 31. The guide wheel 342 is rotatably installed on the supporting shaft 341, and is slidably connected with the supporting shaft 341 along the axial direction of the supporting shaft 341. The outer periphery of the guide wheel 342 is provided with a guide groove 3421 which is used to abut against the fiber between the fiber disc 40 and the traction assembly 33.
[0037] The fiber unwinding device 30 provided by the embodiments of the present application can make the guide groove 3421 of the guide wheel 342 of the guide assembly 34 abut against the fiber between the fiber disc 40 and the traction assembly 33, and make the guide wheel 342 rotatably installed on the supporting shaft 341 and slidably connected with the supporting shaft 341 along the axial direction of the supporting shaft 341. Thus, the guide wheel 342 can guide the fiber between the fiber disc 40 and the traction assembly 33, and when the fiber between the fiber disc 40 and the guide wheel 342 has a large deflection angle along the axial direction of the fiber disc 40 during the unwinding of the fiber disc 40, the component of the force applied by the fiber to the guide wheel 342 along the axial direction of the supporting shaft 341 can push the guide wheel 342 to move along the supporting shaft 341, so as to reduce the deflection angle of the fiber between the fiber disc 40 and the guide wheel 342 along the axial direction of the fiber disc 40, thereby reducing the tension of the fiber and reducing the problem that the fiber is damaged due to the large tension.
[0038] In some embodiments, the guide assembly 34 further comprises an elastic structure 343 which is connected with the guide wheel 342 and is used to apply an elastic force to the guide wheel 342 along the axial direction of the supporting shaft 341. Thus, the elastic structure 343 can provide the guide wheel 342 with an elastic force to reset the guide wheel 342, and the guide wheel 342 can be automatically reset under the action of the elastic structure 343 when the tension of the fiber is reduced.
[0039] The elastic structure 343 can include a first elastic component 3431 for connecting with the guide wheel 342 and applying a first elastic force to the guide wheel 342 along the axial direction of the support shaft 341. In addition, the elastic structure 343 further includes a second elastic component 3432 for connecting with the guide wheel 342 and applying a second elastic force to the guide wheel 342 along the axial direction of the support shaft 341, the direction of the second elastic force being opposite to that of the first elastic force. Thus, the guide wheel 342 is kept at the central position by the first elastic component 3431 and the second elastic component 3432 respectively applying elastic forces in opposite directions. When the guide wheel 342 moves a certain distance along either end of the axial direction of the support shaft 341 under the pulling of the optical fiber, it can be automatically reset to the central position under the action of the first elastic component 3431 or the second elastic component 3432, so that the guide wheel 342 is consistent with the central position of the optical fiber disc 40 as much as possible, so as to release the tension of the optical fiber as much as possible.
[0040] The first elastic component 3431 can be sleeved on the support shaft 341, and located between the guide wheel 342 and the mounting frame 32. One end of the first elastic component 3431 is used for abutting against the mounting frame 32, and the other end of the first elastic component 3431 is used for connecting with the guide wheel 342 and applying the first elastic force to the guide wheel 342. Thus, the installation of the first elastic component 3431 can be more stable, and the first elastic component 3431 can stably apply the first elastic force to the guide wheel 342.
[0041] In addition, the support shaft 341 can further include an abutting portion 3411 located on the side of the guide wheel 342 away from the mounting frame 32. The second elastic component 3432 is sleeved on the support shaft 341 and located between the guide wheel 342 and the abutting portion 3411. One end of the second elastic component 3432 is used for abutting against the abutting portion 3411, and the other end of the second elastic component 3432 is used for abutting against the guide wheel 342 to apply the second elastic force to the guide wheel 342. Thus, the installation of the second elastic component 3432 can be more stable, and the second elastic component 3432 can stably apply the second elastic force to the guide wheel 342.
[0042] In the embodiments of the present application, the first elastic component 3431 and the second elastic component 3432 can be springs, torsional springs, rubbers or any elastic components capable of applying elastic forces to the guide wheel 342, which are not limited herein. In addition, the first elastic component 3431 and the second elastic component 3432 can be different elastic components or the same component, as long as they can apply the first elastic force and the second elastic force to the guide wheel 342.
[0043] In some embodiments, asFigure 3 and Figure 4 As shown in FIG. 3, the width of the guide groove 3421 along the axial direction of the support shaft 341 can gradually decrease from the groove opening to the groove bottom. In this way, the optical fiber can be guided to the bottom of the guide groove 3421 by the inner side of the guide groove 3421, so as to improve the guiding effect of the guide wheel 342 on the optical fiber.
[0044] Specifically, the guide groove 3421 of the guide wheel 342 extends along the circumferential direction of the guide wheel 342 in a ring shape. The intersection line between the inner surface of the guide groove 3421 of the guide wheel 342 and the axial section of the guide wheel 342 is a symmetrical hyperbolic structure, so that the guide groove 3421 has a better guiding effect on the optical fiber.
[0045] In some embodiments, the material of the guide wheel 342 includes polytetrafluoroethylene and a conductive agent. In this way, the hardness and the friction coefficient of the guide wheel 342 can be reduced, which is beneficial to reduce the abrasion of the guide wheel 342 on the optical fiber. At the same time, the guide wheel 342 can also prevent static electricity.
[0046] In some embodiments, the guide wheel 342 can be rotatably supported on the support shaft 341 by a bearing, so as to reduce the friction between the guide wheel 342 and the support shaft 341, and make the rotation of the guide wheel 342 more smooth.
[0047] In some embodiments, the fiber releasing wheel 31 has a damping function. In this way, the fiber releasing wheel 31 can establish a proper fiber releasing tension on the optical fiber disc 40, and the structure is relatively simple, which replaces a relatively complex and space-occupying tension adjusting floating roller, and is beneficial to reduce the cost of the fiber releasing device 30.
[0048] In some embodiments, the guide assembly 34, the traction assembly 33 and the fiber releasing wheel 31 can be located on the same side of the mounting frame 32, so as to facilitate the installation of the optical fiber disc 40 on the fiber releasing wheel 31, and the connection of the optical fiber wound on the optical fiber disc 40 with the guide assembly 34 and the traction assembly 33, and reduce the deflection angle of the optical fiber in the axial direction of the fiber releasing wheel 31, which is beneficial to reduce the tension on the optical fiber.
[0049] In some embodiments, the guide assembly 34 is located above the traction assembly 33, the guide assembly 34 and the traction assembly 33 are located on the same side of the fiber releasing wheel 31, and the height of the support shaft 341 relative to the bottom of the mounting frame 32 is greater than the height of the fiber releasing wheel 31 relative to the bottom of the mounting frame 32.
[0050] In some embodiments, as shown in FIG. 4, the guide assembly 34 can be located on the same side of the traction assembly 33 and the fiber releasing wheel 31. Figure 2As shown, the traction assembly 33 can include a traction wheel 331, a driving mechanism (not shown in the figure) and a crimping mechanism 332, the traction wheel 331 is rotatably installed on the mounting frame 32, the outer periphery of the traction wheel 331 is provided with a wheel groove 3311 for accommodating the optical fiber, and a part of the crimping mechanism 332 is located in the wheel groove 3311 and rolls against the bottom surface of the wheel groove 3311. Thus, the crimping mechanism 332 and the bottom surface of the wheel groove 3311 can clamp the optical fiber located in the wheel groove 3311, and when the crimping mechanism 332 and the traction wheel 331 relatively roll, the optical fiber can be pulled to move.
[0051] In the traction assembly 33, the driving mechanism can be connected with the traction wheel 331, and the driving mechanism is used to drive the traction wheel 331 to rotate, so as to pull the optical fiber clamped between the bottom surface of the wheel groove 3311 and the crimping mechanism 332 to move. Specifically, the driving mechanism can be a motor, the motor is installed on the mounting frame 32, and the rotating shaft of the motor is directly or indirectly connected with the traction wheel 331 through a speed reduction mechanism, so as to drive the traction wheel 331 to rotate.
[0052] Alternatively, the driving mechanism can also be connected with the crimping mechanism 332, and the driving mechanism is used to drive the crimping mechanism 332 to drive the traction wheel 331 to rotate, so as to pull the optical fiber clamped between the bottom surface of the wheel groove 3311 and the crimping mechanism 332 to move. Specifically, the crimping mechanism includes a crimping belt 3321 and two pulleys 3322, the two pulleys 3322 are rotatably installed on the mounting frame 32, and the two pulleys 3322 are connected through the crimping belt 3321. A part of the crimping belt 3321 is located in the wheel groove 3311 and rolls against the bottom surface of the wheel groove 3311, so that the crimping belt 3321 clamps the optical fiber located in the wheel groove 3311 with the bottom surface of the wheel groove 3311. The driving mechanism is connected with one of the two pulleys 3322 and drives the pulley 3322 to rotate, so as to drive the crimping belt 3321 to move, and then drive the traction wheel 331 to rotate through the crimping belt 3321, so as to pull the optical fiber to move.
[0053] In some embodiments, as shown in the figure, the fiber placing device 30 can further include a first guide cylinder 351 for guiding the optical fiber located between the guide assembly 34 and the traction assembly 33 to pass through, and a second guide cylinder 352 for guiding the optical fiber pulled by the traction assembly 33 to pass through.
