Description

Technical Field

[0001] The present invention relates to an optical fiber cabling device and a system comprising the same, which is suitable for processing optical fiber cabling and additionally performing at least one of cable cutting and cable winding in an automated manner. Background Art

[0002] Traditionally, the fiber optic cable industry has relied on single-machine assistance for cable cutting, meaning one person per machine, per process. Semi-automatic equipment can measure and cut fiber lengths, but manual work is required for subsequent winding and bundling. The difficulty in automating bundling operations, as well as the difficulty integrating cutting and winding operations, are major obstacles to achieving full automation in the fiber optic cable cutting and winding process. This inevitably leads to extensive manual labor, high labor costs, and low production efficiency.

[0003] In the technical solution disclosed in the patent document with announcement number "CN210312854U", invention name "A new type of fully automatic optical fiber cable cutting equipment" and publication date of April 14, 2020, an automatic cable tying device is arranged at the front end of the equipment frame. The automatic cable tying device includes a cable winding device, a winding drum and a winding frame. The winding drum is connected to the winding frame through a winding shaft; the winding frame is connected to the equipment frame through a pushing cylinder.

[0004] When the winding drum rotates to the set number of meters, it will automatically tighten and when the cylinder on the rotating shaft of the automatic tightening mechanism is loosened, the tied optical fiber line can be pushed into the material collection turnover box on both sides.

[0063] The present invention will be further described below with reference to the accompanying drawings and examples. In the following detailed description, exemplary embodiments of the present invention are described by way of illustration only. It is understood that those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and are not intended to limit the scope of the claims.

[0064] Figure 1 and Figure 2 A system including a cable tying device is shown, which can be called a "fully automatic optical fiber cable cutting, cable winding and cable tying integrated device". In the embodiment described below, it includes a device that can perform cable laying, cable cutting, cable extension, cable winding and other processes.

[0065] The system includes a frame 1 as a supporting base of the system. Conventionally, the frame 1 is a combination of aluminum profiles and plates, which is well known to those skilled in the art and will not be described in detail here.

[0066] A fiber cable is a coil of fiber optic cable. The fiber being transmitted typically consists of the optical fiber and a protective coating, which includes an inner PVC layer, a reinforcing polyester material, and an outer PVC layer. The fiber cable is terminated with ceramic ferrules at both ends, allowing it to be used as a fiber optic patch cord. For simplicity, in the following description, fiber optic cable is also referred to as optical fiber.

[0067] like Figure 1 and Figure 2 As shown, a cable payout device 2 is installed on one side of the frame 1. A cable winding device 6 is also installed on the frame 1. A tensioning device 4, a metering device 3, and a cable cutting device 5 are located sequentially between the payout device 2 and the cable winding device 6. A cable reeling device 7 is installed on the frame 1 to transport the optical fiber 9 from the cable cutting device 5 to the cable winding device 6. A cable tying device 8 is also installed on the frame 1 to correspond to the cable winding device 6. During normal operation, the payout device 2 pays out the optical fiber 9, which then passes through the tensioning device 4, the metering device 3, and the cable cutting device 5 to the cable winding device 6 for winding. After the metering device 3 measures the optical fiber 9 to a predetermined length, the cable cutting device 5 cuts the optical fiber 9. The cable winding device 6 finally winds the optical fiber 9 into a cable roll 91. The cable tying device 8 bundles the cable roll 91. After the bundled cable roll 91 is removed, the cable reeling device 7 transports the cut optical fiber 9 from the cable cutting device 5 to the cable reeling device 7 to continue winding the next cable roll 91.

[0068] like Figure 4 and Figure 6As shown, the cable winding device 6 includes a cable winding main shaft 61 rotatably mounted on the frame 1, and at least two circumferentially evenly distributed cable winding support arms 62 are fixedly provided on the cable winding main shaft 61. In this embodiment, there are four cable winding support arms 62. At least one of the cable winding support arms 62 is installed with a cable supporting movable rod 64 that can move away from the cable winding main shaft 61, and the remaining cable winding support arms 62 are fixed with cable supporting fixed rods 63. The cable supporting movable rod 64 and the cable supporting fixed rod 63 together form a winding structure that can wind the optical fiber 9. In this embodiment, two cable winding support arms 62 are installed with cable supporting movable rods 64, and the remaining two cable winding support arms 62 are fixed with cable supporting fixed rods 63, and the cable supporting movable rods 64 and the cable supporting fixed rods 63 are staggered with each other. The cable supporting movable rod 64 is connected to a cable winding tension controller 65; a cable winding starting end fixer 66 is provided on the cable winding main shaft 61. Each support arm 62 is usually arranged parallel to the cable winding main shaft 61. Figure 6 Only one cable roll 91 is shown wound on the cable winding device 6. Figure 1 As shown, the length provided by each support arm 62 in the cable winding device 6 can allow multiple cable rolls 91 to be wound simultaneously.

[0069] After the starting end of the optical fiber 9 is delivered to the cable winding device 6, it is secured by the cable starting end fixture 66. The cable winding tension controller 65 controls the cable support movable rod 64 to move away from the cable winding main shaft 61, which is then driven to rotate, and the optical fiber is wound around the cable support movable rod 64 and the cable support fixed rod 63 in turns. When the winding and bundling are complete, the cable winding tension controller 65 controls the cable support movable rod 64 to move toward the cable winding main shaft 61, loosening the cable roll 91 and allowing it to be easily withdrawn.

[0070] In this embodiment, the cable support rod 64 is slidably mounted on the corresponding cable winding support arm 62 via two guide rail slider structures, and the sliding direction is radially along the cable winding main shaft 61. The cable winding tension controller 65 is a cable winding tension control cylinder. The cylinder body of the cable winding tension control cylinder is fixedly connected to the cable winding main shaft 61, and the piston rod of the cable winding tension control cylinder is fixedly connected to the cable support rod 64. The cable support rod 64 can be moved away from or toward the cable winding main shaft 61 by extending and retracting the cable winding tension control cylinder. Of course, this embodiment can also be achieved by swinging a movable rod swing arm at the end of the cable winding support arm 62, and fixing the cable support rod 64 on the movable rod swing arm to achieve the movable installation of the cable support rod 64. In this case, the cable winding tension controller 65 is a pneumatic cylinder or electric cylinder hinged between the movable rod swing arm and the corresponding cable winding support arm 62. This technical solution can also achieve the movement of the cable support rod 64 away from or toward the cable winding main shaft, and is also within the scope of protection of the present invention.

[0071] In the embodiment described later, the cable tying device 8 ties one cable reel 91 and then ties the next cable reel 91 by moving, that is, the tying of the cable reels 91 at each location shares one cable tying device 8, but in another embodiment, if the control rhythm of the system requires, a cable tying device 8 can be set separately for the cable reel 91 at each location.

[0072] The cable tying device 8 includes a cable tying base 81 provided on the frame 1, on which a cable tying feed seat 82 is slidably mounted and arranged to slide toward the cable winding device 6, and a cable tying feed driver 821 is provided between the cable tying feed seat 82 and the cable tying base 81; a cable tying wire entry guide 83 is fixedly provided on the cable tying feed seat 82 and is located on one side of the cable reel 91; a cable tying wire return guide arm 84 is rotatably mounted on the cable tying feed seat 82, and the cable tying wire return guide arm 84 is connected to the return guide driver; a cable tying wire supply device 86 is provided on the cable tying feed seat 82, and a cable tying wire cutting device 87 is provided on the cable tying feed seat 82 between the cable tying wire supply device 86 and the cable tying wire entry guide 83; and a tying device is provided on the cable tying feed seat 82. By providing the cable tying feed seat 82, the cable tying device 8 can be brought as close to the cable winding device 6 as possible, and when the cable winding device 6 is in operation, the position can be adjusted to maintain an appropriate distance from the cable winding device 6. In another embodiment, the cable feeding seat 82 may be omitted, for example, the movement of the cable feeding seat 82 may be replaced by the displacement of the cable winding device 6 .

[0073] According to the embodiment shown in the figure, after the cable winding device 6 winds the fixed-length optical fiber 9 into a cable reel 91, the cable feed driver 821 first drives the cable feed seat 82 toward the cable reel 91, and the wire entry guide 83 eventually reaches the cable reel 91. The wire return guide driver drives the wire return guide arm 84 to rotate toward the inside of the cable reel 91, and eventually forms a complete wire guide channel with the wire entry guide 83. The wire supply device 86 can easily wind along this complete wire guide channel, entering from one side of the cable reel 91 and then winding out from the other side of the cable reel 91. After the wire cutting device 87 cuts the wire, the entire section of wire at the cable reel 91 is U-shaped under the action of the complete wire guide channel. The tying device can easily use the two ends of this section of wire to perform tying operations. The embodiment of the tying device will be described below by way of example.

[0074] The wire return guide arm 84 of this embodiment includes a wire return swing section 841 rotatably mounted on the cable feed seat 82. The end of the wire return swing section 841 is fixed with an arc-shaped wire return guide section 842. The wire return guide section 842 can form a complete wire return guide channel with the wire return guide 83. Preferably, the wire return guide section 842 and the wire return guide 83 are provided with a wire return guide groove. The wire return guide groove of the wire return guide section 842 is inclined, such as Figure 8As shown, the wire guide groove of the return wire guide section 842 is inclined to the left, that is, toward the other side of the cable reel 91, which is consistent with the forward swinging direction of the return wire guide section 842. This is conducive to the wire being stably guided from the right side to the left side of the cable reel 91.

[0075] The wire return guide driver includes a wire return drive slider 85 slidably mounted on the cable feed seat 82. The wire return drive slider 85 is connected to a slider feed driver 851. A wire return guide transmission link 852 is provided between the wire return drive slider 85 and the wire return guide arm 84. When the sliding feed driver drives the wire return drive slider 85 to feed the cable reel 91, the wire return guide transmission link 852 can push the wire return guide arm 84 to swing inward of the cable reel 91. The wire return guide transmission link 852 is shown as a rod in the embodiment shown in the figure, but is not limited to this. In addition to being a rod, it can also be other components as long as it can transmit the movement output by the wire return drive slider 85 to the wire return guide arm 84. For example, another embodiment of the wire return guide transmission link 852 is a special-shaped groove corresponding to the trajectory of the end of the wire return guide arm 84, and the special-shaped groove cooperates with the hinge axis of the wire return guide transmission link 852. In this embodiment, the slider feed driver 851 includes a slider feed drive disk 853 rotatably mounted on the cable feed seat 82. The slider feed drive disk 853 is connected to a slider feed drive motor 854. The slider feed drive disk 853 is provided with an eccentric connecting shaft 855. A slider feed drive connecting rod 856 is hingedly connected between the eccentric connecting shaft 855 and the return drive slider 85. Through the above structure, the slider feed drive disk 853, the slider feed drive connecting rod 856, and the return drive slider 85 constitute a crank slider mechanism. Because the slider feed drive motor 854 is blocked, only the end of the motor shaft is shown in the figure. Driven by the slider feed drive motor 854, the return drive slider 85 can drive the return guide arm 84 to swing toward the inside of the cable reel 91 within its travel range, or drive the return guide arm 84 to return to its original position. Of course, the slider feed driver 851 can also be directly implemented using an electric cylinder, a pneumatic cylinder, or a motor in conjunction with a screw drive. The advantage of using the slider crank mechanism as shown in the figure is that the wire return guide arm 84 can be driven and positioned in multiple positions, and the space occupied is short and the cost is low. In addition, the return guide drive can also be directly implemented using structures such as electric cylinders or pneumatic cylinders.

[0076] The cable-binding wire supply device 86 includes a cable-binding wire supply driving wheel 861 rotatably mounted on the cable-binding wire feed seat 82. The cable-binding wire supply driving wheel 861 is connected to a cable-binding wire supply drive motor, which is obscured in the figure and not shown. A cable-binding wire holding seat 862 is slidably mounted on the cable-binding wire feed seat 82. A cable-binding wire supply driven wheel 863 corresponding to the cable-binding wire supply driving wheel 861 is rotatably mounted on the cable-binding wire holding seat 862. A cable-binding wire holding force applicator 864 is provided between the cable-binding wire holding seat 862 and the cable-binding wire feed seat 82. The cable-binding wire holding force applicator 864 drives the cable-binding wire holding seat 862 to maintain a pressure on the cable-binding wire supply driving wheel 861, thereby effectively clamping the cable-binding wire with the cable-binding wire supply driving wheel 861. When the cable-binding wire supply drive motor drives the cable-binding wire supply driving wheel 861 to rotate, the cable-binding wire is supplied. The cable-binding wire holding force applicator 864 can also be implemented using a spring or the like. In this embodiment, a cable reel 865 is installed on the cable feeding seat 82 or the cable base 81. The cable 100 is drawn out from the cable reel 865, and then passes through between the driving wheel 861 and the driven wheel 863 after pre-traction, and is clamped by the driving wheel 861 and the driven wheel 863 and frictionally driven.

[0077] The wire cutting device 87 includes a wire cutting base 871 fixedly mounted on the cable feed seat 82 and located between the wire supply device 86 and the wire entry guide 83. The wire cutting base 871 is provided with a wire passage hole 872. A wire cutting tool 873 is slidably mounted on the wire cutting base 871 at the end of the wire passage hole 872. The wire cutting tool 873 is connected to a wire cutting controller. The embodiment of the wire cutting controller will be described exemplarily below. The wire passage hole 872 is linear and tangential to the clamping position of the driving wheel 861 and the driven wheel 863, i.e., the output direction of the transmitted wire.

[0078] The tying wires outputted by the tying wire supply device 86 first pass through the tying wire through hole 872 and then reach the tying wire inlet guide 83. When the tying wire output length is sufficient, for example, Figure 9 In the state shown, the wire cutting controller controls the wire cutting tool 873 to slide. Figure 15As shown, the wire cutting tool 873 and the end of the wire passage hole 872 can form a cutting effect on the wire 100. In this embodiment, the cross-section of the wire cutting tool 873 is square, and the wire cutting base 871 is provided with a square sliding hole corresponding to the wire cutting tool 873, thereby forming a sliding installation for the wire cutting tool 873. The wire passage hole 872 guides the wire, forcing the wire to be transferred to a position that the wire cutting tool 873 can reach. The wire passage hole 872 also serves to limit the lateral movement of the wire. When the wire cutting tool 873 moves from right to left to reach the position where the wire is tied, the cutting edge of the wire cutting tool 873 tends to push the wire to move, but the wire is restricted by the lateral movement prevention of the wire passage hole 872, so the wire does not move, and the wire cutting tool 873 continues to move to the left, thereby cutting the wire. In another embodiment, the shape of the wire-binding hole 872 is not limited to a square, but can be any other shape. The hole has essentially the same meaning as a seam, a groove, or a channel. It can be the inner surface of a continuous material or the inner surface of a hollow material, as long as it plays a role in preventing lateral displacement and guiding.

[0079] In this embodiment, the wire tie return guide arm 84 and the wire tie entry guide 83 are located on the same side of the cable reel 91. The wire cutting controller includes a wire cutting transmission wheel 874 rotatably mounted on the wire cutting tool 873, a wire cutting force-applying inclined surface 876 corresponding to the wire cutting transmission wheel 874 is provided on the wire return drive slider 85, and a wire cutting return spring 875 is provided between the wire cutting tool 873 and the wire cutting base 871. During the bundling operation, the wire supply device 86 first outputs the wire and makes the end of the wire reach the wire entry guide 83. The wire return drive slider 85 is driven close to the cable reel 91, and the wire cutting force-applying inclined surface 876 thereon passes through the wire cutting transmission wheel 874, causing the wire cutting tool 873 to gradually approach the wire passing hole 872. Figure 9 Can be used as an exemplary starting point for the wire cutting tool 873, Figure 10 In the state shown, the wire cutting tool 873 moves a distance to the left from the starting point, and the cutting edge of the wire cutting tool 873 contacts the wire passing through the wire hole 872. The wire return guide arm 84 swings synchronously toward the inside of the cable reel 91 and gradually forms a long curved wire guide channel with the wire entry guide 83. Figure 9 The wire-binding return guide arm 84 is also in the initial state. Figure 10 The wire return guide arm 84 in the drawing has already played a guiding role in the drawing. Figures 9 to 10 In the process between the states shown, the wire return guide arm 84 swings to the left while the wire is also transmitted downward, and the wire return guide arm 84 guides the wire while swinging. Figure 9 、 Figure 10The wires continuously output by the wire supply device 86 are bent along the increasingly long curved wire guide channel. The bent wires are extended from the other side of the cable roll 91 under the influence of their own plastic deformation and the increasingly long wire guide channel. Finally, as the return line driving slider 85 slides down to the lower limit position or the lower dead point, as shown in FIG. Figure 11 As shown, the wire cutting force inclined surface 876 pushes the wire cutting tool 873 so that the wire cutting tool 873 moves relative to the wire cutting tool 873. Figure 10 The position shown is further moved to the left, and the wire is cut. The wire return guide arm 84 is further swung to the left, that is, it is swung in the forward direction, and it forms a final complete wire guide channel with the wire entry guide 83. The cut section of the wire forms a circuitous shape at the cable roll 91, such as a U shape, and the two ends of the wire pass through the tying device, that is, they reach the position where the tying device can perform tying operations.

[0080] In one embodiment, the tying device includes a tying spindle 88 mounted on the cable feeding seat 82. An S-shaped tying hook 881 is fixedly provided at one end of the tying spindle 88 close to the cable reel 91. A tying hook 882 is fixedly provided at each end of the tying hook 881. The tying drive motor is connected to the tying spindle 88. When the tying wire at the cable reel 91 forms a U-shape, the tying drive motor drives the tying spindle 88 to rotate. The two tying hooks 882 first contact the two ends of the U-shaped tying wire and lead it to rotate around the tying spindle 88. During the rotation process, the two ends of the U-shaped tying wire interact in a spiral manner and approach the tying hook 881. As the tying spindle 88 continues to rotate, the two ends of the tying wire are finally tied in a spiral manner, and the tying drive motor can be stopped.

[0081] Figure 12 The figure shows the state of the tying device after completing the bundling process. During the tying process, the wire return drive slider 85 usually remains stationary. Accordingly, the wire cutting tool 873 and the wire return guide arm 84 remain stationary. The wire return guide arm 84 maintains the wire in a stable position. In another embodiment, during the tying device performing spiral bundling, that is, after the two ends of the wire are spirally wound, the wire return drive slider 85 can be controlled to retract in advance. After the bundling is usually completed, the wire return drive slider 85 is driven back, the wire return guide arm 84 is returned, the wire cutting tool 873 is returned under the action of the wire cutting return spring 875, and the cable feed driver 821 drives the cable feed seat 82 back. The cable roll 91 is then in a state on the cable winding device 6 that can be easily removed. Figure 13 The status shown is Figure 9 Compared with the state shown, the wire cutting tool 873 and the wire return guide arm 84 are both in the exemplary initial state, and the return drive slider 85 is at the upper dead center or upper limit position. Figure 13In the embodiment, the binding wire supply device 86 waits for a control instruction and performs a binding wire supply operation. The binding wire supply operation is usually performed after the cable roll 91 is pulled out.

[0082] like Figure 6 As shown, a cable reel dispensing base 893 is slidably mounted on the frame 1, and a cable reel dispensing rod 89 which can be extended to one side of the cable reel 91 is slidably mounted on the cable reel dispensing base 893, and a reel dispensing driver 891 is provided between the cable reel dispensing rod 89 and the cable reel dispensing base 893, and a cable reel dispensing driver is provided between the cable reel dispensing base 893 and the frame 1. It will be understood from the following description that the cable reel dispensing driver and the transposition cable tying driver 811 are configured as the same driver, and accordingly, the cable reel dispensing base 893 and the cable tying base 81 are different parts of the same base, which is driven by the aforementioned driver. Figure 6 The cable reel 91 is moved and adjusted in the forward and backward directions as shown. One embodiment of the driver is a motor connected to a ball screw mechanism 8112. The motor can be replaced by other rotation output devices, such as a belt mechanism 8810. After the cable reel 91 is tied, the two cable reel tension controllers 65 respectively control the corresponding cable support movable rods 64 to move closer to the cable winding main shaft 61, and the cable reel 91 is relaxed. The reel positioning driver 891 drives the cable reel lever 89 to extend, as shown in FIG. Figure 6 As shown, in the upper and lower directions, two cable reel levers 89 are connected to the upper and lower sides of the same lever feed seat 892. The lever feed seat 892 is slidably mounted on the cable reeling base 893 via a slide rail mechanism. Due to the large space between the cable support movable rod 64 and the cable support fixed rod 63, the upper and lower cable reel levers 89 can easily reach one side of the cable reel 91. The cable reeling drive then controls the entire sliding of the cable reeling base 893, and the cable reel levers 89 can remove the cable reel 91 from the cable winding device 6, completing an automatic reeling operation. In another embodiment, the reeling drive 891 can be implemented using an electric cylinder or a pneumatic cylinder, and the cable reeling drive can be implemented using an electric cylinder, a pneumatic cylinder, or a motor in conjunction with a screw drive. A lever feed seat 892 is slidably mounted on the cable reel unwinding base, a reel-in-place driver 891 is disposed between the lever feed seat 892 and the cable reel unwinding base, and two cable reel unwinding levers 89 are fixedly mounted on the lever feed seat 892, thereby achieving a better unwinding effect on the cable reel 91. In response to multiple tied cable reels 91, the cable reel unwinding base 893 or the cable tying base 81 is provided with such a cable unwinding mechanism on the front and rear sides, so that multiple cable reels 91 can be unwound from the cable reeling device simultaneously in one unwinding operation.

[0083] As mentioned above, the system including the cable bundling device is exemplified by a fully automatic optical fiber cable cutting, cable winding and cable bundling integrated device, which also includes devices for implementing cable release, cable cutting and cable extension.

[0084] according to Figure 1 and Figure 2In the illustrated embodiment, the optical fiber 9 released from the cable payout device 2 passes through the tensioning device 4 and reaches the meter counter 3. The starting end of the optical fiber 9 is clamped by the fiber-removal clamp 77 in the cable reel 7. At this point, the meter counter 3 resets the number of revolutions for the length of the optical fiber 9. The optical fiber 9 then passes from the cable reel 7 over the cable cutting device 5 to the cable winding start-end fixture 66 of the cable winding device 6. During the reeling process, the meter counter 3 begins counting. After the starting end of the optical fiber 9 is secured, the cable reel 7 returns to its original position, and the cable winding spindle 61 is driven to rotate, allowing the optical fiber 9 to be wound around the cable support fixed rod 63 and the cable support movable rod 64. When the meter counter 3 detects that the designated number of revolutions has been reached, the optical fiber 9 has been wound to the specified length. The fiber-removal clamp 77 on the cable reel 7 clamps the optical fiber 9 between the cable cutting device 5 and the meter counter 3, retaining the position at which the optical fiber 9 was last clamped. The cable cutting device 5 cuts the optical fiber 9, and the cable winding spindle 61 stops rotating after a predetermined delay. The optical fiber 9 forms a cable reel 91 on the cable winding spindle 61. The cable binding device 8 bundles the cable reel 91. After bundling, the cable binding device 8 returns to its original position, and the cable reel 91 is pulled out by the cable reel lever 89. The cable re-winding device 7 then delivers the optical fiber 9 to the cable winding start-end fixture 66 of the cable winding device 6 for the next round of cable winding. This embodiment achieves fully automated cable cutting, winding, and bundling operations, reducing manpower and labor costs while improving production efficiency.

[0085] The cable payout device 2 includes a cable payout frame 21. The cable payout frame 21 can be integrated with the frame 1 or separately fixed relative to the frame 1. This embodiment illustrates the latter. A cable payout mounting shaft 22 is rotatably mounted on the cable payout frame 21. A fiber optic reel 23 is mounted on the cable payout mounting shaft 22. A cable payout drive 24 is connected to the cable payout mounting shaft 22. The cable payout drive 24 rotates the cable payout mounting shaft 22, paying out the optical fiber 9. Once all optical fibers 9 on the fiber optic reel 23 have been wound, they can be manually replaced.

[0086] The meter counting device 3 includes a fixed meter counting wheel 31 rotatably mounted on the frame 1. A meter counting pressing seat 32 is movably mounted on the frame 1. A movable meter counting wheel 33 corresponding to the fixed meter counting wheel 31 is rotatably mounted on the pressing seat 32. A meter counting pressing force is provided between the pressing seat 32 and the frame 1. A rotation sensor 34 is connected to either the movable meter counting wheel 33 or the fixed meter counting wheel 31. Under the action of the pressing force, the pressing seat 32 effectively clamps the movable meter counting wheel 33 and the fixed meter counting wheel 31. When the optical fiber 9 advances under the force of the cable winding, it drives the movable meter counting wheel 33 and the fixed meter counting wheel 31 to rotate. The length of the optical fiber 9 advanced can be calculated by multiplying the circumference of the movable meter counting wheel 33 or the fixed meter counting wheel 31 by the corresponding number of revolutions. This embodiment illustrates the installation of a rotation sensor 34 on the movable meter counting wheel 33. The length of the optical fiber 9 is calculated by multiplying the circumference of the movable meter counting wheel 33 by the number of revolutions. Of course, the signal of the rotation speed sensor 34 is connected to the electrical controller, and the output signal of the electrical controller is connected to the cable cutting device 5.

[0087] This embodiment shows a meter counter pressing seat 32 that is swingably mounted on the frame 1 and positioned above the meter counter movable wheel 33. The meter counter pressing seat 32 also serves as a meter counter pressing force applicator. The weight of the meter counter pressing seat 32 and its components, such as the movable meter counter wheel 33, the speed sensor 34, and the bearings, causes the movable meter counter wheel 33 and the fixed meter counter wheel 31 to clamp the light. Of course, the meter counter pressing force applicator of this embodiment can also be a meter counter pressing force spring separately disposed between the meter counter pressing seat 32 and the frame 1, further strengthening the clamping effect between the movable meter counter wheel 33 and the fixed meter counter wheel 31 through the spring force. Furthermore, the meter counter pressing seat 32 of this embodiment can also be slidably mounted on the frame 1. Under the action of the meter counter pressing force applicator, the meter counter pressing seat 32 approaches the fixed meter counter wheel 31, similarly forming a clamping effect between the movable meter counter wheel 33 and the fixed meter counter wheel 31. This technical solution is also within the scope of protection of the present invention.

[0088] In an alternative embodiment, the meter counting device includes a sensor and the aforementioned cable winding device. The sensor counts the rotational speed of the cable winding device and calculates the length of the optical fiber transmitted or reeled based on the rotational speed of the cable winding device. This alternative embodiment omits the meter counting wheel and the holding seat, resulting in a simpler structure and lower design, manufacturing, and maintenance costs.

[0089] The tensioning device 4 includes a downward tensioning seat 41 that slides vertically on the frame 1. A downward tensioning pulley 42 is rotatably mounted on the downward tensioning seat 41. The optical fiber 9 supplied by the cable payout device 2 passes through the downward tensioning pulley 42 and then ascends to the metering device 3. This embodiment utilizes the gravity of the downward tensioning seat 41 and the downward tensioning pulley 42 to achieve tensioning of the optical fiber 9. This gravity effect is relatively small and is less likely to damage the structure of the optical fiber 9. This embodiment illustrates the installation of a cable payout guide pulley 25 on the cable payout frame 21, which is higher than the tensioning device 4. This allows for smoother sliding of the downward tensioning seat 41 and more efficient use of the tensioning seat. In this embodiment, the downward tensioning seat 41 is mounted vertically and slidably via two guide rods.

[0090] In actual use, the cable winding speed of the cable winding device 6 and the cable unwinding speed of the cable unwinding device 2 may not necessarily form an exact match. When the cable winding speed of the cable winding device 6 is greater than the cable unwinding speed of the cable unwinding device 2, the length of the optical fiber 9 at the tensioning device 4 will shorten, and the tensioning force of the optical fiber 9 itself will drive the downward tensioning seat 41 to rise. Conversely, when the cable winding speed of the cable winding device 6 is less than the cable unwinding speed of the cable unwinding device 2, or even when the cable winding speed of the cable winding device 6 is zero, such as when the cable cutting device 5 cuts the cable and the cable tying device 8 is bundling it, the length of the optical fiber 9 at the tensioning device 4 will increase, causing the downward tensioning seat 41 to descend. This is to avoid unnecessary problems caused by the optical fiber 9 being too short or too long at the tensioning device 4.

[0091] On the other hand, as the amount of cable released by cable payout device 2 increases, while its cable payout speed remains constant, the amount of cable released decreases due to the decrease in cable thickness. This is equivalent to a change in the cable winding and unwinding speeds between cable winding device 6 and cable payout device 2, which can also cause mismatching between the two. The tensioning device 4 moves up and down, and the amount of up and down movement represents the buffer length of the buffered optical fiber. This buffer length is used to dynamically adapt to changes in the cable winding speed of cable winding device 6 and the unwinding speed of cable payout device 2.

[0092] In this embodiment, the frame 1 is equipped with a highest position sensor and a lowest position sensor corresponding to the downward tensioning seat 41. These sensors detect the highest and lowest positions of the downward tensioning seat 41, respectively, ensuring that the length of the optical fiber 9 at the tensioning device 4 is always maintained within a certain range. The highest and lowest position sensors are also connected to the electrical controller, whose output signals are connected to the cable payout device 2. The highest and lowest position sensors are not shown in the figure, and photoelectric sensors, Hall effect sensors, or other position sensors can be used.

[0093] The cable cutting device 5 mainly comprises two cutting blades for cutting the optical fiber 9. Figure 16As shown, the cable cutting device 5 includes a fixed blade holder 54 and a movable blade holder 52. The fixed blade holder 54 provides a movable channel 540, and the movable blade holder 52 is disposed within the movable channel 540. The fixed blade holder 54 is provided with a wire passing slot 541 and a wire cutter 55. The cutting edge of the wire cutter 55 extends into the wire passing slot 541. Correspondingly, the movable blade holder 52 is provided with a plurality of wire cutters 56. The wire cutters 56 can move to a position where they meet the wire cutters 55. This meeting position is located in the wire passing slot 541. The movable blade holder 52 is driven by a wire cutting actuator 51. One embodiment of the wire cutting actuator 51 is a pneumatic cylinder. When the movable blade holder 52 moves to separate the two wire cutters 55 and 56, the optical fiber 9 can pass through the wire passing slot 541. When the two wire cutters 55 and 56 meet and then intersect during the movement of the movable blade holder 52, the optical fiber 9 in the wire passing slot 541 is cut. As will be understood from the following description, the end of the optical fiber 9 cut upstream of the cable cutting device 5 is clamped by the cable re-cable device 7, namely, by the fiber-taking clamp 77. The cable re-cable device 7 then pulls the optical fiber 9 through the cable trough 541 and transfers it to the cable winding device 6, where it is clamped and begins winding. The power for the optical fiber 9 to be transmitted forward is provided solely by the cable winding device 6. Therefore, many components that intermediately drive the optical fiber 9, such as the stepper motor, driving wheel, driven wheel, pressure cylinder, wire feed roller, and wire feed nozzle, can be omitted, effectively simplifying the number of structural components of the mechanism. Since one station of the cable re-cable device 7 is located upstream of the cable cutting device 5, even if the optical fiber 9 is cut by the cable cutting device 5 and loses driving power, the optical fiber 9 is still maintained in a tensioned state. At the same time, in conjunction with the aforementioned buffer system, the optical fiber 9 can be continuously maintained in a tensioned state before being pulled by the cable re-cable device 7 to the cable winding device 6 for winding.

[0094] The cable winding start end fixer 66 is used to fix the optical fiber 9 at the start end of the cable winding device 6 to prevent it from slipping during the winding process. This embodiment shows that the cable winding start end fixer 66 is a finger cylinder fixedly set on the cable winding main shaft 61, and clamping blocks are respectively set on the two fingers of the finger cylinder. This technology is easy to understand for those skilled in the art based on the description and the prior art, and will not be repeated here. This embodiment shows that two cable winding start end fixers 66 are symmetrically set on the cable winding main shaft 61. When the cable winding device 6 finishes a cable winding operation, it is preferred to control the cable winding start end fixer 66 to be in a vertical state, which can facilitate the cable renewal device 7 to directly fix the start end after delivering the start end of the next wave of optical fiber 9.

[0095] The cable reel 7 includes a reel shift slide 73 slidably mounted on the frame 1. A reel fiber removal slide 75 is vertically slidably mounted on the reel shift slide 73. A fiber removal clamp 77 is provided on the reel fiber removal slide 75. A fiber removal feed driver 76 is provided between the reel fiber removal slide 75 and the reel shift slide 73. A reel shift driver 74 is provided between the reel shift slide 73 and the frame 1. Before the cable cutting device 5 cuts the optical fiber 9, the reel shift driver 74 drives the reel shift slide 73 to slide above the cable cutting device 5 (the first working position). The fiber removal feed driver 76 drives the reel fiber removal slide 75 downward, and the fiber removal clamp 77 clamps the optical fiber 9 in front of the cable cutting device 5. After the cable cutting device 5 cuts the optical fiber 9, the clamping action of the fiber removal clamp 77 ensures that the optical fiber 9 between the fiber removal clamp 77 and the cable payout device 2 does not move. When the bundled cable reel 91 is unplugged and the next wave of optical fiber 9 is to be wound, the fiber take-off feed driver 76 drives the cable take-off slide 75 to rise, and the cable shift driver 74 drives the cable shift slide 73 to slide to the cable winding device 6 (the second station). The position of the optical fiber 9 clamped by the fiber take-off clamp 77 is the starting point of the aforementioned cable winding. According to the height of the cable winding starting end fixture 66 at this time, the fiber take-off feed driver 76 drives the cable take-off slide 75 to move up and down a certain amount. Finally, the starting point of the optical fiber 9 clamped by the fiber take-off clamp 77 is on the cable winding starting end fixture 66. After the cable winding starting end fixture 66 fixes the starting end, the fiber take-off clamp 77 releases the clamp, the cable winding device 7 returns to its position, and the cable winding device 6 can perform the cable winding operation.

[0096] In this embodiment, the cable extension shift driver 74 and the fiber taking feed driver 76 can be realized by using a cylinder, an electric cylinder or a motor in combination with a screw drive, and the fiber taking clamp 77 is also realized by a finger cylinder.

[0097] according to Figure 1 and Figure 2 In the illustrated embodiment, the aforementioned cable payout, cable cutting, cable extension, cable winding, and cable tying can be performed in parallel along multiple paths. In this embodiment, the cable payout device 2 includes six fiber optic reels 23 positioned on a cable payout frame 21, three on each side. The three fiber optic reels 23 on the same side pay out the cable simultaneously.

[0098] Corresponding to the optical fibers 9 released from the three optical fiber reels 23 on each side, three tensioning devices 4 and three metering devices 3 are respectively provided; the lengths of the cable support fixing rod 63 and the cable support movable rod 64 are lengthened, and three pairs of cable winding starting end fixers 66 are provided on the cable winding main shaft 61; three fiber retrieval clamps 77 are provided on the cable extension and fiber retrieval slide 75 in the cable extension device 7.

[0099] In the cable renewing device 7, a transposition cable renewing slide 71 is provided between the cable renewing shift slide 73 and the frame 1, and the cable renewing shift slide 73 is slidably mounted on the transposition cable renewing slide 71; the transposition cable renewing slide 71 is slidably mounted on the frame 1 and can move between the cable cutting devices 5 on both sides, and a transposition cable renewing driver 72 is provided between the transposition cable renewing slide 71 and the frame 1. By driving the transposition cable renewing driver 72 to slide the transposition cable renewing slide 71, the cable renewing device 7 can renew the three optical fibers 9 on one side and then renew the three optical fibers 9 on the other side.

[0100] Similarly, in the cable tying device 8 of this embodiment, the cable tying base 81 is installed on the frame 1 for transverse sliding, and a transposition cable tying driver 811 is provided between the cable tying base 81 and the frame 1. By driving the sliding of the cable tying driver 811, the cable tying base 81 can perform bundling operations on three cable reels 91 on one side in sequence, and then move to the other side to perform bundling operations on another three cable reels 91 in sequence.

[0101] Due to the sliding installation of the cable tying base 81, the cable reel dispensing base of this embodiment is fixedly connected to the cable tying base 81. Specifically, the cable tying base 81 also serves as the cable reel dispensing base, and the cable transposition driver 811 also serves as the cable reel dispensing driver. This makes this embodiment more compact. After the cable tying device 8 completes the bundling operation of the three cable reels 91 on one side, the cable tying structure in the cable tying device 8 returns to its original position. The cable transposition driver 811 drives the cable tying base 81 to the side of the three cable reels 91 on that side. The cable dispensing driver 891 drives the cable reel dispensing lever 89 to extend. The cable transposition driver 811 drives the cable tying base 81 to slide, and the cable reel dispensing lever 89 dispensing the three cable reels 91 on that side. To facilitate the separate dispensing of the cable reels 91 on both sides, a dispensing lever feed seat 892 is slidably mounted on each side of the cable tying base 81. Each dispensing lever feed seat 892 is equipped with a cable reel dispensing lever 89 and a dispensing lever driver 891. After being pulled out, the cable reel lever 89 returns to its original position, and the cable-binding driver 811 drives the cable-binding base 81 to the other side where the three cable reels 91 are positioned.

[0102] Through the above structural optimization, in this embodiment, while one side is performing cable cutting, cable bundling, cable reeling and cable extension, the other side can simultaneously perform cable winding, thus achieving a continuous cable winding operation, greatly improving the overall efficiency of cutting, winding and bundling the optical fiber 9. Specifically, the transposition cable extension driver 72 and the transposition cable bundling driver 811 can both be implemented using structures such as electric cylinders, pneumatic cylinders, or motors in conjunction with screw transmissions.

[0103] This embodiment achieves fully automated operation for bundling optical fibers 9, particularly the entire process from laying out the cables to bundling them. This reduces manpower and labor costs, and improves production efficiency. Furthermore, through a rational structural arrangement, the overall efficiency of the automated operation is greatly improved, resulting in high economic and social value.

[0104] The basic principles, main features, and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and modifications are intended to fall within the scope of the present invention.
