Description

Technical Field

[0001] The present disclosure generally relates to the field of composite cable connection technology, and in particular to a power cable connection device and method. Background Art

[0002] In the field of modern power communications, the application of power communication composite cables is becoming more and more widespread. They can transmit power and communication signals at the same time, providing a strong guarantee for the stable operation of various systems.

[0003] However, the splicing problem of composite cables has always been a key problem that needs to be solved urgently in the industry.

[0004] The traditional composite cable splicing method usually adopts the step-by-step operation of metal wire and optical fiber. This method has many disadvantages. First, it is extremely inefficient, requires a lot of time and labor costs, and increases the construction period and operating costs. Secondly, the core alignment accuracy is poor, and deviations are prone to occur during the manual core alignment process, resulting in a decrease in signal transmission quality and affecting the stability of communication and power transmission.

[0005] In addition, the optical fiber is easily damaged during the splicing process. Since the processing procedures of the metal wire and the optical fiber are separated and the operation is complicated, the optical fiber may break if you are not careful during the operation, which will seriously affect the overall performance of the cable.

[0006] Moreover, it is difficult to accurately control the stripping range of the metal wire with existing splicing technology, and irreparable damage may be caused to the internal optical fiber when stripping the metal wire.

[0007] At the same time, traditional welding methods cannot achieve uniform circumferential welding of metal wires, resulting in uneven welding quality and affecting the long-term performance of the cable.

[0008] Therefore, there is an urgent need for a composite cable splicing technology that is efficient, high-precision and can avoid damaging optical fibers to meet the power communication industry's demand for reliable splicing of composite cables. Summary of the invention

At the same time, the fusion splicer mounting arm drives the optical fiber fusion splicer to move to the position of the exposed optical fiber for splicing. After the optical fiber splicing is completed, the rotary spot welding mechanism slides around the metal wire along the arc-shaped servo slide rail, and the spot welding assembly is driven by the rotary drive assembly to continuously rotate and spot weld around the axis of the composite cable to achieve circumferentially uniform welding of the metal wires.

The fusion splicer mounting arm and the rotary spot welding mechanism are executed step by step to avoid process interference. The core-alignment torsion mechanism calibrates the axial positions of the internal metal wires and optical fibers in the composite cable by synchronous rotation, avoiding the deviation of traditional manual core alignment and improving the splicing reliability. The inclined feeding design of the metal wire stripping structure can accurately control the stripping range of the metal wires to prevent damage to the optical fibers. The rotary spot welding mechanism realizes the rapid and continuous circumferential welding of the metal wires through the coordinated movement of the arc-shaped servo slide rail and the rotary drive assembly, greatly improving the welding efficiency and consistency. The optical fiber fusion splicer and the metal wire welding module are integrated into the same device, reducing the process switching time. The inclined linkage design of the stripping block and the first telescopic mechanism provides a stable operation space for optical fiber splicing while pushing the metal wires away, reducing the risk of optical fiber breakage. The fusion splicer mounting arm is independently arranged on the upper part of the mounting frame to avoid spatial interference with the metal wire welding module. The arc-shaped servo slide rail supports the multi-angle welding path adjustment of the rotary spot welding mechanism, adapting to different composite cable diameters and metal wire arrangement forms, enhancing the versatility of the device, and improving the technical problems of low operation efficiency, poor core alignment accuracy, and easy damage to optical fibers in the traditional splicing of composite cables. It is applicable to the high-efficiency and high-precision splicing scenario of power communication composite cables.

[0032] In order to make the objectives, solutions and advantages of the technical solutions of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments of the present disclosure. Unless otherwise specified, the terms used herein have the ordinary meanings in the art. The same reference numerals in the drawings represent the same components.

[0033] In the description of the present disclosure, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present disclosure can be understood according to specific situations.

[0034] As described above, in the traditional construction of connecting composite cables, since the composite cable is composed of multiple types of wire materials and the connection methods of each type of wire material are different, it is necessary to rely on manual operation for separate connections, resulting in problems such as low connection efficiency and poor connection quality.

[0035] To at least partially solve one or more of the above problems and other potential problems, please refer to Figures 1-9 , the exemplary embodiments of the present disclosure provide a power cable wiring device, which includes: Two groups of core-aligning torsion mechanisms 1, symmetrically arranged on both sides of the wiring ends of two composite cables 9 and detachably connected to the composite cables 9; Mounting frame 2, with two groups of core-aligning torsion mechanisms 1 mounted on the upper part; Torsion drive assembly 3, arranged between the core-aligning torsion mechanism 1 and the mounting frame 2, driving the core-aligning torsion mechanism 1 to rotate around the axis of the composite cable 9; Two sets of wire stripping structures 4 are spaced apart and provided at the lower part of the mounting frame 2; among them The wire stripping structure 4 includes: A first telescopic mechanism 41 is provided on the lower surface of the mounting frame 2, and the telescopic end is inclined and pointed at the composite cable 9; A stripping block 42 is provided at the telescopic end of the first telescopic mechanism 41; The wiring device further includes: An arc-shaped servo slide rail 5 is installed between the stripping blocks 42 of the two sets of wire stripping structures 4; A rotary spot welding mechanism 6 is slidably installed in the arc-shaped servo slide rail 5; The rotary spot welding mechanism 6 includes: A rotary drive assembly 61 is slidably connected to the arc-shaped servo slide rail 5; A spot welding assembly 62 is provided at the drive end of the rotary drive assembly 61, and the rotary drive assembly 61 drives the spot welding assembly 62 to rotate around the axis of the composite cable 9; A splicer mounting arm 7 is provided at the upper part of the mounting frame 2, and an optical fiber splicer is installed at one end of the splicer mounting arm 7 away from the mounting frame 2.

[0036] In the above embodiments, two groups of core-alignment torsion mechanisms 1 symmetrically clamp both ends of the composite cable 9, and rotate around the cable axis through the torsion drive assembly 3 to drive the cable to twist synchronously, so that the internal metal wires 92 and the optical fibers 91 are axially aligned, ensuring the subsequent splicing accuracy. The first telescopic mechanism 41 of the metal wire stripping structure 4 pushes the stripping block 42 to feed obliquely towards the cable, and uses the mechanical action of the stripping block 42 to push the metal wire 92 to both sides. At the same time, the fusion splicer mounting arm 7 drives the fiber optic fusion splicer to move to the position of the exposed optical fiber 91 for splicing. After the splicing of the optical fiber 91 is completed, the rotary spot welding mechanism 6 slides around the cable along the arc-shaped servo slide rail 5, and the spot welding assembly 62 is driven by the rotary drive assembly 61 to continuously rotate and spot weld around the cable axis, realizing the circumferentially uniform welding of the metal wire 92. The splicing of the optical fiber 91 and the welding of the metal wire 92 are completed through the integration of the same device. The fusion splicer mounting arm 7 and the rotary spot welding mechanism 6 are executed step by step to avoid process interference. The core-alignment torsion mechanism 1 calibrates the axial positions of the internal metal wire 92 and the optical fiber 91 in the cable by synchronous rotation, avoiding the deviation of traditional manual core alignment and improving the splicing reliability. The inclined feeding design of the metal wire stripping structure 4 can accurately control the stripping range of the metal wire 92 and prevent damage to the optical fiber 91. The rotary spot welding mechanism 6 realizes the rapid and continuous circumferential welding of the metal wire 92 through the coordinated movement of the arc-shaped servo slide rail 5 and the rotary drive assembly 61, greatly improving the welding efficiency and consistency. The fiber optic fusion splicer and the metal wire 92 welding module are integrated into the same device, reducing the process switching time. The inclined linkage design of the stripping block 42 and the first telescopic mechanism 41 provides a stable operation space for the splicing of the optical fiber 91 while pushing the metal wire 92 away, reducing the risk of optical fiber 91 breakage. The fusion splicer mounting arm 7 is independently arranged on the upper part of the mounting frame 2 to avoid spatial interference with the metal wire 92 welding module. The arc-shaped servo slide rail 5 supports the multi-angle welding path adjustment of the rotary spot welding mechanism 6, adapts to different cable diameters and the arrangement forms of the metal wire 92, enhances the versatility of the device, and solves the technical problems of low efficiency of step-by-step operation of the metal wire 92 and the optical fiber 91, poor core alignment accuracy, and easy damage to the optical fiber 91 in the traditional splicing of the composite cable 9, and is applicable to the high-efficiency and high-precision splicing scenario of the power communication composite cable 9.

[0038] In the above embodiments, when fixing the composite cable 9, the composite cable 9 is placed on the inner wall of the C-shaped clamping arm 11 with an arc-shaped chute 14. Subsequently, another C-shaped clamping arm 11 is placed on the other side of the composite cable 9, and the two C-shaped clamping arms 11 are connected by a fastening bolt 13. Thus, the composite cable 9 is clamped between the inner walls of the two C-shaped clamping arms 11 to achieve the fixation of the composite cable 9.

In the above embodiments, when the torsion drive assembly 3 works, the output shaft of the first motor 33 rotates and drives the first driving gear 32 to rotate, so that when the first driving gear 32 rotates, it drives the driven gear 34 meshing with it to rotate. Then, the rotation of the driven gear 34 drives the first arc-shaped rack 35 meshing with it to make a circular motion around the central axis of the two C-shaped clamping arms 11, so that the two C-shaped clamping arms 11 can twist the composite cable 9 respectively. When the two C-shaped clamping arms 11 rotate, the two groups of positioning sliders 36 slide in the two arc-shaped chutes 14 respectively.

[0040] Please refer to Figures 1-9 , in some embodiments, the first telescopic mechanism 41 includes: A base 411, mounted on the lower surface of the mounting frame 2, and the upper part of the base 411 is inclined backward and points to the composite cable 9; Two groups of first electric push rods 412, spaced apart and mounted on the inclined surface of the upper part of the base 411, and the telescopic ends are connected to the stripping block 42; A guide ring 413, sleeved on the circumferential outer wall of the first electric push rod 412; The guiding rod 414 has one end connected to the peeling block 42 and the other end connected to the end wall of the guiding ring 413. The peeling block 42 includes: Two groups of diamond-shaped vertical plates 421 with openings at the included angles near the composite cable 9; among them The guiding rod 414 penetrates through the included angles at one ends of the two groups of diamond-shaped vertical plates 421 away from the open ends. A triangular prism 422 with both ends disposed inside the inner rings of the two groups of diamond-shaped vertical plates 421. One of the side edges of the triangular prism 422 is disposed close to the guiding rod 414 and is connected to the guiding rod 414. The bottom plate 423 has both ends connected to one ends of the two diamond-shaped vertical plates 421 close to the guiding ring 413, and the middle section of the bottom plate 423 is connected to the telescopic end of the first electric push rod 412. The arc-shaped servo slide rail 5 is disposed between the two groups of peeling blocks 42, and the curved surface of the arc-shaped servo slide rail 5 faces the open ends of the diamond-shaped vertical plates 421. Two groups of curved spring pieces 424 are symmetrically disposed on the inner walls of the diamond-shaped vertical plates 421, and the curved surfaces of the two groups of curved spring pieces 424 face the optical fiber 91 of the composite cable 9. The electromagnetic induction sensor 425 is installed at the open end of the diamond-shaped vertical plate 421. The optical time domain reflectometer 426 has the light-emitting diode at the detection end disposed at the open end of the diamond-shaped vertical plate 421. The control unit is electrically connected to the electromagnetic induction sensor 425 and the first electric push rod 412, and is used to control the first electric push rod 412 to stop moving when the electromagnetic induction sensor 425 detects the disappearance of the metal wire 92.

[0041] In the above embodiments, when the first telescopic mechanism 41 works, the first electric push rod 412 extends, driving the peeling block 42 to feed towards the composite cable 9. During this process, the first electric push rod 412 pushes the opening angle of the diamond-shaped vertical plate 421 towards the two metal wires 92. When the diamond-shaped vertical plate 421 abuts between the two metal wires 92, the first electric push rod 412 continues to extend, causing the first electric push rod 412 to continue pushing the diamond-shaped vertical plate 421 to slide on the guide rod 414 towards the triangular prism 422. The inner walls on both sides of the angle at one end of the diamond-shaped vertical plate 421 close to the triangular prism 422 move along the two adjacent faces of the triangular prism 422, causing the adjacent faces of the triangular prism 422 to push the angle of the diamond-shaped vertical plate 421 to continuously increase, and the vertical plates on both sides of the open end of the diamond-shaped vertical plate 421 to push the two metal wires 92 to expand outwards, achieving the purpose of separating the metal wires 92. When the diamond-shaped vertical plate 421 completely separates the two metal wires 92, the two sets of curved spring pieces 424 arranged inside the diamond-shaped vertical plate 421 are clamped against the outer wall of the optical fiber 91 to stabilize the optical fiber 91. During the movement of the diamond-shaped vertical plate 421, the electromagnetic induction sensor 425 detects the state of the metal wire 92 in real time. When the metal wire 92 disappears, it directly transmits an electrical signal to the control unit. A shielding baffle can be arranged on one side of the electromagnetic induction sensor 425, so that when the electromagnetic induction sensor 425 passes by the metal wire 92, the detection signal is blocked, triggering the first electric push rod 412 to stop immediately; the optical time domain reflectometer 426 (OTDR) collects data of the optical fiber 91 through a light-emitting diode and transmits the measurement result to the data processing module through a communication interface. After the data processing module analyzes and calculates the relative distance between the optical fiber 91 and the metal wire 92, it feeds back the calibration parameters to the control unit; the control unit combines the direct shutdown instruction of the electromagnetic induction sensor 425 and the optical fiber 91 state data of the OTDR to form a double insurance mechanism, dynamically controlling the action of the electric push rod to ensure the safe coordination of the metal wire 92 and the optical fiber 91 during the peeling and fusion process, and finally achieving the efficient and accurate connection of the composite cable 9.

[0045] In the above embodiment, when the spot welding assembly 62 needs to be driven to rotate around the metal wire 92, the second motor 618 is started, so that the second motor 618 drives the second driving gear 617 to rotate. Then, the rotation of the second driving gear 617 drives the second arc-shaped rack 616 engaged with it to rotate around the central axis of the C-shaped mounting plate 612, so that the second arc-shaped rack 616 drives the C-shaped mounting plate 612 to rotate. The openings of the C-shaped mounting plate 612, the C-shaped limiting plate 614, the C-shaped sliding plate 613, and the C-shaped baffle 615 are used for the composite cable 9 to enter the rotation driving assembly 61. When the C-shaped mounting plate 612 makes a circular motion, the C-shaped sliding plates 613 on both sides of the C-shaped mounting plate 612 slide and rotate on the inner wall of the C-shaped limiting plate 614, and the C-shaped limiting plate 614 limits the rotation when the C-shaped sliding plate 613 and the C-shaped mounting plate 612 make a circular motion. When the C-shaped mounting plate 612 rotates around the metal wire 92, the spot welding assembly 62 is started, and the resistance of the metal wire 92 between the welding cable 623 and the welding torch 622 increases. When the current passes through, this section of the metal wire 92 is melted and welded together, realizing continuous spot welding at the interface on the outer circumference of the metal wire 92.

[0046] Please refer to Figures 1-9 , in some embodiments, the wiring device further includes: The skin assembly 8, and the skin assembly 8 is installed on one side of the rotation driving assembly 61; The skin assembly 8 includes: Two groups of C-shaped mounting rods 80 are provided, and the two groups of C-shaped mounting rods 80 are symmetrically arranged on both sides of the C-shaped mounting plate 612, and the C-shaped mounting rods 80 are arranged at an interval from the C-shaped baffle 615; among them The C-shaped mounting rod 80 is fixedly connected to the side wall of the C-shaped baffle 615 through an extension rod 81; A plurality of steering wheels 82 are provided, and the plurality of steering wheels 82 are installed at intervals on the outer circumference of the C-shaped mounting rod 80, and the traveling directions of the steering wheels 82 are parallel to the length direction of the composite cable 9; A track 83 is provided between the two bottom plates 423, the length direction of the track 83 is perpendicular to the plane where the arc-shaped servo slide rail 5 is located, and an auxiliary slider 84 is provided on the side of the arc-shaped servo slide rail 5 close to the track 83, and the auxiliary slider 84 slides in the track 83; The skin assembly 8 further includes: The material roller 85 is rotatably installed on the inner wall of the C-shaped mounting plate 612, and a polyvinyl chloride film 86 is wound around the outer circumference of the material roller 85; The guide wheel 87 is provided in the C-shaped mounting plate 612; The spring pull rod 88 has a guide wheel 87 rotatably installed at one end and is installed on the inner wall of the C-shaped mounting plate 612 at the other end; The L-shaped spring piece 89 has one end disposed at the telescopic end of the second electric push rod 621 and the other end passing through the PVC film 86.

[0047] In the above embodiment, after welding is completed, the C-shaped mounting plate 612 is driven by the steering wheel 82 to move on the metal wire 92 and is driven by the second motor 618 to rotate. The second electric push rod 621 pushes the L-shaped spring piece 89 to contact the outer wall of the metal wire 92, so that the PVC film 86 on the L-shaped spring piece 89 is wound around the outer wall of the metal wire 92 structure, achieving the effect of automatic skinning. During the winding process, the C-shaped mounting plate 612 drives the PVC film 86 to continuously wind around the surface of the metal wire 92.

[0048] Please refer to Figures 1-9 , the exemplary embodiments of the present disclosure also provide a wiring method, including the following steps: S1. Pretreat the butt-end cable: Manually level the butt-end interfaces of the two composite cables 9 and cut the skin of the exposed part of the metal wire 92. S2. Core alignment and calibration: Install the pretreated composite cables 9 into the core-twisting mechanisms 1 symmetrically arranged respectively, and synchronously rotate the two groups of composite cables 9 through the twisting drive assembly 3 to axially align the internal metal wires 92 and optical fibers 91 respectively. S3. Metal wire 92 stripping and positioning: Drive the first telescopic mechanism 41 of the two groups of metal wire stripping structures 4 to feed obliquely towards the composite cable 9, and use the electromagnetic induction sensor 425 on the stripping block 42 to detect the position of the metal wire 92. When the sensor parameter changes from increasing to decreasing, it is determined that the edge of the metal wire 92 is contacted. S4. Optical fiber 91 exposure control: Based on the optical time domain reflectometer 426 to detect the position data of the optical fiber 91, dynamically adjust the stroke of the first telescopic mechanism 41 through the control unit, so that the two side stripping blocks 42 push the metal wire 92 outwards to a predetermined distance, completely exposing the middle optical fiber 91. S5. Optical fiber 91 fusion and detection: Control the fusion splicer mounting arm 7 to move the optical fiber fusion splicer to the butt-joint position for fusion splicing. After fusion splicing is completed, scan and detect the fusion splicing integrity along the axial direction of the optical fiber 91 through the optical time domain reflectometer 426. S6. Metal wire 92 reset welding: After confirming that the optical fiber 91 fusion splicing is qualified, retract the stripping block 42 to make the metal wire 92 reset and contact, and drive the rotary spot welding mechanism 6 to continuously spot weld and fix around the metal wire 92 along the arc-shaped servo slide rail 5.

[0049] In the above embodiments, the exposed skin of the metal wire 92 at the butt end of the composite cable 9 is manually cut off and the end face is flattened to ensure that the end structures of the two composite cables 9 are the same. The pre-treated cables are respectively installed on the core alignment and torsion mechanisms 1 arranged symmetrically. The two groups of composite cables 9 are synchronously rotated by the torsion drive assembly 3, so that the internal metal wires 92 and the optical fibers 91 are automatically axially aligned, eliminating the connection deviation caused by the torsion or offset of the wire cores. The first telescopic mechanism 41 of the metal wire stripping structure 4 is driven to push the stripping block 42 towards the composite cable 9 at an inclined angle. The contact state of the metal wire 92 is detected in real time by the electromagnetic induction sensor 425 integrated in the stripping block 42. When the sensor parameter suddenly changes from increasing to decreasing, it is determined that the stripping block 42 contacts the edge of the metal wire 92. Combining with the axial position data of the optical fiber 91 detected by the optical time domain reflectometer 426 (OTDR), the control unit dynamically adjusts the stroke of the first telescopic mechanism 41, so that the two side stripping blocks 42 precisely push the metal wire 92 to a preset distance, completely exposing the middle optical fiber 91 and avoiding damage. The optical fiber fusion splicer is moved to the exposed position by the installation arm 7 of the fusion splicer to complete the fusion splicing. The OTDR scans the reflection loss value of the fusion splice point along the axial direction of the optical fiber 91 to determine the fusion splicing integrity. After the fusion splicing is qualified, the stripping block 42 is withdrawn, and the metal wire 92 is reset and fitted. The rotary spot welding mechanism 6 is driven to slide circumferentially around the composite cable 9 along the arc-shaped servo slide rail 5 for continuous spot welding fixation.
