Description

Technical Field

[0001] The present application relates to the technical field of optical fiber collection devices, and in particular to a broken optical fiber collection device. Background Art

[0002] When a fiber breaks, workers may not immediately detect the break, resulting in a significant amount of fiber not being effectively collected between the main pulling mechanism and the take-up machine. This waste is only reduced by proactively reducing the speed after the break is discovered. Furthermore, workers must manually reduce the drawing speed to around 15 m / min before manually winding the fiber onto the reels. Furthermore, the entire fiber-reeling process requires assistance from a nearby operator. During the period between retrieving and increasing the speed to normal drawing speed, a significant number of defective fibers, such as those with coating defects, are generated.

[0003] Therefore, in the prior art, when an optical fiber is broken, there will be problems such as optical fiber waste, reduced collection efficiency and labor costs. Utility Model Content

[0037] Figure 1 1 is a front structural diagram of a broken optical fiber collection device 100 according to an embodiment of the present invention. Figure 2 for Figure 1Schematic diagram of the rear view of the optical fiber broken fiber collection device 100 of the embodiment. Figure 1 As shown, in one embodiment, a fiber break collection device 100 includes a traversing mechanism 10, a pinch roller assembly 20, a fiber pressing mechanism 30, a temporary take-up reel 40, a clamp 50, and a cutting element 60. The traversing mechanism 10 includes a traversing wheel 11. The pinch roller assembly 20 is positioned downstream of the traversing wheel 11 and includes a movable traction wheel 21 and a drive traction wheel 22. The movable traction wheel 21 is positioned to approach the drive traction wheel 22 when a fiber break occurs downstream of the pinch roller assembly 20, thereby clamping the fiber and driving the traction wheel 22 to rotate and continue conveying the fiber. The fiber pressing mechanism 30 is positioned at a first position between the traversing wheel 11 and the pinch roller assembly 20. When a fiber break occurs, the fiber pressing mechanism 30 is configured to press a target fiber segment located in the first position downward to a target position. The target fiber segment is the fiber segment between the traversing wheel 11 and the pinch roller assembly 20. The temporary take-up reel 40 is positioned upstream of the fiber pressing mechanism 30 and is configured to rotatably collect the fiber. The clamp 50 is fixed to the temporary take-up reel 40 and is used to clamp the target fiber segment when it is pressed down to the target position. The cutting member 60 is located at a second position between the clamp 50 and the pressure wheel assembly 20. The cutting member 60 is used to cut the target fiber segment at the second position and can be located relatively close to the clamp 50. The various mechanisms in this embodiment can be fixed to the mounting base 70.

[0038] The optical fiber broken fiber collection device 100 is arranged upstream of the take-up machine. When the optical fiber is collected normally, the optical fiber starts from the main traction, passes through the main traction end passing wheel 80, the line wheel 11, the movable traction wheel 21 and the driving traction wheel 22, and is guided to the take-up machine. The take-up machine is located downstream of the pressing wheel group 20, that is, Figure 1 The right side of the middle pinch wheel assembly 20. The optical fiber broken collection device 100 of this embodiment is used to be activated when a fiber break occurs downstream of the pinch wheel assembly 20, and is used to temporarily continue collecting optical fibers.

[0039] This embodiment provides a temporary collection device for broken fibers. When a fiber break occurs, the device first clamps the optical fiber using the movable traction wheel 21 and the drive traction wheel 22. The fiber pressing mechanism 30 then presses the optical fiber down to a position where the clamp 50 can clamp the optical fiber. The optical fiber is then severed by the cutting member 60. The temporary take-up reel 40 rotates to continue collecting the optical fiber until the internal reel and broken optical fibers are cleaned and the take-up machine is ready to operate again. This broken fiber collection device 100 can automatically continue collecting optical fibers when a fiber break occurs, without requiring downtime or excessive manual intervention. This ensures collection efficiency, reduces labor costs, and prevents waste of optical fiber.

[0040] In one embodiment, the temporary take-up reel 40 is configured to rotate while the clamp 50 is clamping the target fiber segment. The cutting element 60 is fixedly positioned and severs the target fiber segment as the temporary take-up reel 40 rotates. In other words, the cutting element 60 does not need to be moved; as the temporary take-up reel 40 rotates, the fiber segment is naturally severed by the cutting element 60.

[0041] like Figure 1 As shown, in one embodiment, the cable traversing wheel 11 is configured to move axially along the temporary take-up drum 40 and is located above the temporary take-up drum 40, thereby limiting the surface flatness of the optical fibers collected on the temporary take-up drum 40. The cable traversing wheel 11 is also configured to move horizontally to guide broken fibers closer to the take-up machine. Specifically, the bidirectional movement of the cable traversing wheel 11 can be achieved through the following mechanism.

[0042] like Figure 1 As shown, the cable arrangement mechanism 10 further includes a first moving mechanism, which includes a cable arrangement motor 121, a turntable 122, a cable arrangement connecting rod 123, a cable arrangement slider 124 and a cable arrangement guide rail 125. Figure 2 As shown, the cable traversing motor 121 is arranged on the back of the mounting base 70. The output shaft of the cable traversing motor 121 is connected to the turntable 122. One end of the cable traversing connecting rod 123 is hinged to the turntable 122. Here, the hinge position of the cable traversing connecting rod 123 and the turntable 122 is located at the edge of the turntable 122. The cable traversing guide rail 125 is arranged in front of the mounting base 70 and extends along the axial direction of the temporary take-up drum 40. The cable traversing slider 124 can slide relative to the cable traversing guide rail 125. The cable traversing slider 124 is hinged to the end of the cable traversing connecting rod 123 away from the turntable 122. Figure 1 As shown, a through hole is provided at the slider for passing a connecting shaft 126, one end of which is rotatably connected to the cable traversing connecting rod 123, and the other end of which is fixedly connected to the cable traversing wheel 11. When the output shaft of the cable traversing motor 121 rotates, the cable traversing wheel 11 can move along the axial direction of the temporary cable take-up drum 40, so that the cable traversing wheel 11 corresponds to the current winding position on the temporary cable take-up drum 40. The grooves on the outer circumference of the cable traversing wheel 11 are used to limit the flatness of the outer circumference formed by the optical fiber wound on the temporary cable take-up drum 40.

[0043] Further, if Figure 1 As shown, the first moving mechanism also includes a moving seat 127 for fixing the cable traversing motor 121, the turntable 122, the cable traversing connecting rod 123, the cable traversing slider 124 and the cable traversing guide rail 125. A horizontally arranged upper fiber guide rail 134 is also fixed on the mounting base 70. The moving seat 127 cooperates with the upper fiber guide rail 134 and is configured to be movable relative to the upper fiber guide rail 134. Figure 2As shown, the back of the mounting base 70 is also provided with an upper fiber screw 131 and an upper fiber motor for driving the upper fiber screw 131. Bearings 132 and the upper fiber motor are respectively provided at each end of the upper fiber screw 131. A screw pair is formed between the movable base 127 and the upper fiber screw 131, so that when the upper fiber motor drives the upper fiber screw 131 to rotate, the movable base 127 is driven to move. Of course, in other embodiments not shown, other movable drive mechanisms can also be used to drive the cable traversing wheel 11 in both directions, and this is not limited here.

[0044] After completing the preparations for reactivating the take-up machine, the cable arrangement wheel 11 is controlled to move horizontally to drive the optical fiber to a position close to the take-up machine so that the employee can rewind the optical fiber onto the take-up machine's cable wheel at the take-up machine. The take-up machine completes the reel change by itself. At this time, the movable traction wheel 21 and the drive traction wheel 22 are separated, the temporary take-up reel 40 stops rotating, and the cable arrangement wheel 11 returns to its position and no longer moves, and is used as a guide wheel.

[0045] The cable arrangement mechanism 10 of this embodiment can realize the axial movement and horizontal movement of the cable arrangement wheel 11 along the temporary cable take-up drum 40. When moving axially along the temporary cable take-up drum 40, it can ensure that the surface of the optical fiber on the temporary cable take-up drum 40 is flat. When moving horizontally, it can guide the optical fiber to the cable take-up machine when rewinding normally, making it convenient for employees to rewind the optical fiber onto the cable take-up machine's wire wheel so as to quickly resume normal winding.

[0046] Further, if Figure 1 As shown, the fiber pressing mechanism 30 includes a first cylinder 31 and a second cylinder 33 (see Figure 2 The first cylinder 31 includes a crimping portion 32 that can be extended and retracted along the axial direction of the temporary take-up drum 40. The crimping portion 32 is used to extend when a fiber break occurs. The crimping portion 32 can be hook-shaped, for example Figure 1 The inverted L-shape shown in the figure can effectively limit the optical fiber and prevent it from sliding out from the front. The second cylinder 33 is connected to the first cylinder 31 and is used to drive the first cylinder 31 downward when a fiber break occurs, so that the bottom of the crimping part 32 presses down the target section of optical fiber.

[0047] Further, if Figure 2 As shown, the driving traction wheel 22 is also connected to a driving motor 23, which drives the driving traction wheel 22 to rotate. The driving motor 23 is arranged on the back of the mounting base 70. Figure 1 As shown, a traction wheel cylinder 24 connected to the movable traction wheel 21 is provided on the front of the mounting base 70, which is used to drive the movable traction wheel 21 to move in the up and down directions. A take-up reel spindle 41 is provided in the middle of the temporary take-up reel 40. The take-up reel spindle 41 is connected to the take-up reel rotation motor 43 on the back of the mounting base 70. The front end of the take-up reel spindle 41 is locked to the temporary take-up reel 40 and the take-up reel spindle 41 by a large disk clamping nut 42.

[0048] When the movable traction wheel 21 moves downward to clamp the optical fiber, the driving traction wheel 22 rotates to continue to transport the clamped optical fiber downstream.

[0049] Figure 3 This application also provides a control method for the optical fiber broken fiber collection device 100 in the above embodiment, such as Figure 3 As shown, the control method includes the following steps:

[0050] Step S100: When a fiber break occurs downstream of the pinch wheel assembly 20, the movable traction wheel 21 is controlled to move downward to clamp the optical fiber between the movable traction wheel 21 and the driving traction wheel 22, and the driving traction wheel 22 is controlled to rotate to continue conveying the optical fiber.

[0051] Step S200, controlling the fiber pressing mechanism 30 to extend and move downward to press down the target optical fiber segment at the first position;

[0052] Step S300, controlling the clamp 50 to clamp the target optical fiber segment;

[0053] Step S400, controlling the temporary take-up reel 40 to rotate;

[0054] Step S500, controlling the cable traversing wheel 11 to move along the axial direction of the temporary cable take-up rotary disc 122;

[0055] Step S600: When the take-up machine is ready to work, the temporary take-up drum 40 is controlled to stop rotating, the fiber pressing mechanism 30 is reset, the movable traction wheel 21 is moved upward, and the driving traction wheel 22 is stopped;

[0056] Step S700: Control the wire traversing wheel 11 to move horizontally to a position close to the wire take-up machine.

[0057] In step S100, a sensor, such as a camera, can be used to detect fiber breakage. The movement of the arranging wheel 11 in step S500 is determined based on the current position of the optical fiber. The fiber compression mechanism 30 can be reset at any time after the optical fiber is cut, without limitation. After step S700, the system enters the normal take-up process. Throughout this process, the optical fiber continues to be output normally, without the need for downtime or speed reduction.

[0058] By executing the above steps, temporary reeling of the optical fiber can be automatically completed when a fiber break occurs, and semi-automatic optical fiber connection can be performed when normal reeling is restored, which greatly reduces manual participation, saves labor and improves efficiency.

[0059] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
