Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber untwisting, and particularly relates to an anti-twist fiber winding device. Background Art

[0002] When coiling and distributing optical fibers, the optical fibers need to be regularly wound around an optical fiber wheel, which is called fiber winding. Usually, when winding the fibers, the optical fibers are thin, with poor tensile and bending resistance, and the optical fibers are long, so they are prone to torsion during fiber winding. The torsion of the optical fibers will cause stress inside the optical fibers, affecting the transmission performance of the optical fibers. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an anti-twist fiber winding device that can avoid the torsion of optical fibers and reduce the torsion stress of optical fibers.

[0004] To solve the above technical problem, the utility model adopts the following technical solutions:

[0005] An anti-twist fiber winding device includes a base, a vertical frame is provided on the base, a fiber pressing mechanism, a pre-tightening mechanism and a fiber guiding mechanism are provided on the frame, a fiber winding mechanism is provided on the side of the frame. Defining the fiber moving direction as the transverse direction, the fiber winding mechanism moves in the longitudinal direction with the fiber diameter as the pitch for fiber winding.

[0006] As a further improvement of the above technical solution:

[0007] The fiber pressing mechanism includes a supporting wheel, a fiber pressing motor and a fiber pressing component. The supporting wheel is rotatably connected to the frame and connected to the output end of the fiber pressing motor. The optical fiber is laid on the supporting wheel, and the fiber pressing component presses on the optical fiber.

[0008] The fiber pressing component includes two belt wheels and a fiber pressing belt arranged on the two belt wheels. The two belt wheels are rotatably connected to the frame, and the fiber pressing belt presses on the optical fiber.

[0009] The pre-tightening mechanism includes a connecting shaft, a counterweight frame and a guide wheel. The connecting shaft is fixedly penetrated through the frame. The middle part of the counterweight frame is rotatably connected to the connecting shaft, and the guide wheel is rotatably connected to the end of the counterweight frame.

[0010] An adjusting nut is arranged at one end of the counterweight frame away from the guide wheel.

[0011] A torque sensor connected to the counterweight frame is also arranged on the connecting shaft.

[0012] A limiting column for restricting the rotation range of the counterweight frame is also arranged on the frame.

[0013] The fiber guiding mechanism includes a deflecting frame, a transition wheel and a fiber guiding wheel. The deflecting frame is arranged as a triangular frame, one end of which is rotatably connected to the vertical frame and fixed by a nut. The transition wheel and the fiber guiding wheel are respectively rotatably connected to the other two ends.

[0014] The fiber winding mechanism includes a fiber arranging assembly and a fiber winding assembly. The fiber arranging assembly is connected to the vertical frame so as to be movable in the longitudinal direction, and the fiber winding assembly is fixedly installed on the fiber arranging assembly.

[0015] The fiber arranging assembly includes a base, a moving track, a transmission lead screw and a fiber arranging motor. The moving track is laid on the base in the longitudinal direction. The base is slidably mounted on the moving track and is threadedly connected to the transmission lead screw. The transmission lead screw is connected to the output end of the fiber arranging motor.

[0016] The fiber winding assembly includes a fiber winding motor and a fiber wheel. The fiber winding motor is fixedly installed on the base, and the fiber wheel is connected to the output end of the fiber winding motor.

[0017] Compared with the prior art, the advantages of the present utility model are as follows:

[0018] In the present utility model, when winding the fiber, the fiber is pressed by the fiber pressing mechanism, and then a certain pre-tightening force is generated on the fiber through the pre-tightening mechanism. Then the fiber enters the fiber winding mechanism after passing through the fiber guiding mechanism, so as to avoid the torsion of the fiber during winding, reduce the torsional stress in the fiber, and ensure the transmission performance. In addition, during winding, the fiber winding mechanism moves at a pitch equal to the diameter of the fiber, so that the fibers are arranged neatly, further avoiding the torsion of the fiber.

[0023] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0024] As Figure 1 and Figure 2 shown, the anti-twist fiber collecting device of this embodiment includes a base 1, a vertical frame 2 is vertically arranged on the base 1, a fiber pressing mechanism 3, a pre-tightening mechanism 4 and a fiber guiding mechanism 5 are arranged on the vertical frame 2, and a fiber collecting mechanism 6 is arranged on the side of the vertical frame 2. Defining the moving direction of the optical fiber 100 as the transverse direction, the fiber collecting mechanism 6 moves in the longitudinal direction with the diameter of the optical fiber 100 as the pitch for fiber collection. In the present utility model, the fiber pressing mechanism 3 presses the optical fiber 100 during fiber collection, and then the pre-tightening mechanism 4 makes the optical fiber 100 generate a certain pre-tightening force. Then the optical fiber 100 enters the fiber collecting mechanism 6 after passing through the fiber guiding mechanism 5, so as to avoid the optical fiber 100 from twisting during fiber collection, reduce the torsional stress in the optical fiber 100, and ensure the transmission performance. In addition, the fiber collecting mechanism 6 moves with the diameter of the optical fiber 100 as the pitch during fiber collection, making the arrangement of the optical fiber 100 neat and further avoiding the twisting of the optical fiber 100.

[0025] In this embodiment, the fiber pressing mechanism 3 includes a supporting wheel 31, a fiber pressing motor 32 and a fiber pressing assembly 33. The supporting wheel 31 is movably and rotatably connected to the vertical frame 2 and is connected to the output end of the fiber pressing motor 32. The optical fiber 100 is laid on the supporting wheel 31, and the fiber pressing assembly 33 is pressed on the optical fiber 100. In this structure, the fiber pressing motor 32 drives the supporting wheel 31 to rotate to drive the optical fiber 100 to move, and the optical fiber 100 is pressed on the supporting wheel 31 by the fiber pressing assembly 33, effectively avoiding the twisting of the optical fiber 100.

[0026] In this embodiment, the fiber pressing assembly 33 includes two belt pulleys 331 and a fiber pressing belt 332 arranged on the two belt pulleys 331. The two belt pulleys 331 are movably and rotatably connected to the vertical frame 2, and the fiber pressing belt 332 is pressed on the optical fiber 100. In this structure, the optical fiber 100 is pressed by the fiber pressing belt 332, and the pressing effect is good and the optical fiber 100 can be prevented from being damaged.

[0027] In this embodiment, the pre-tightening mechanism 4 includes a connecting shaft 41, a counterweight frame 42 and a guide wheel 43. The connecting shaft 41 is fixedly penetrated through the vertical frame 2, the middle part of the counterweight frame 42 is movably and rotatably connected to the connecting shaft 41, and the guide wheel 43 is movably and rotatably connected to the end of the counterweight frame 42. In this structure, the optical fiber 100 is wound around the guide wheel 43. Since the counterweight frame 42 is movably and rotatably connected to the connecting shaft 41, under the action of gravity, the counterweight frame 42 at one end provided with the guide wheel 43 will rotate downward, thereby generating a pre-tightening force on the optical fiber 100.

[0028] In this embodiment, an adjusting nut 421 is arranged at one end of the counterweight frame 42 away from the guide wheel 43. The arrangement of the adjusting nut 421 facilitates the adjustment of the pre-tightening force.

[0029] In this embodiment, a torque sensor 411 connected to the counterweight frame 42 is further provided on the connecting shaft 41. By providing the torque sensor 411, the torque output can be displayed, and the magnitude of the pre-tightening force can be intuitively displayed.

[0030] In this embodiment, a limit post 21 for restricting the rotation range of the counterweight frame 42 is further provided on the vertical frame 2. By the limit post 21, the rotation range of the counterweight frame 42 is restricted to avoid breaking the optical fiber 100.

[0031] In this embodiment, the optical fiber guiding mechanism 5 includes a direction-changing frame 51, a transition wheel 52, and a fiber guiding wheel 53. The direction-changing frame 51 is arranged as a triangular frame, one end of which is rotatably connected to the vertical frame 2 and fixed by a nut. The transition wheel 52 and the fiber guiding wheel 53 are respectively rotatably connected to the other two ends. In this structure, the angle of the direction-changing frame 51 can be adjusted by the nut, so as to adjust the fiber receiving position. The optical fiber 100 first changes direction through the transition wheel 52 and then enters the fiber receiving mechanism 6 through the fiber guiding wheel 53.

[0032] In this embodiment, the fiber receiving mechanism 6 includes a fiber arranging component 61 and a fiber receiving component 62. The fiber arranging component 61 is connected to the vertical frame 2 so as to be movable in the longitudinal direction, and the fiber receiving component 62 is fixedly installed on the fiber arranging component 61. In this structure, when the fiber receiving component 62 performs the fiber receiving action, the fiber arranging component 61 moves synchronously to ensure that the optical fiber 100 is neatly arranged.

[0033] In this embodiment, the fiber arranging component 61 includes a base 611, a moving track 612, a transmission lead screw 613, and a fiber arranging motor 614. The moving track 612 is laid on the base 1 in the longitudinal direction. The base 611 is slidably installed on the moving track 612 and is threadedly connected to the transmission lead screw 613. The transmission lead screw 613 is connected to the output end of the fiber arranging motor 614. In this structure, the transmission lead screw 613 is driven by the fiber arranging motor 614 to rotate, so as to drive the base 611 to move along the moving track 612, so that the optical fiber 100 is neatly arranged on the fiber receiving component 62.
