Description

Technical Field

[0001] The present invention relates to the technical field of cables, in particular to a composite flexible cable and cable welding equipment. Background Art

[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. Cable is a branch of electric wires. Generally, cables are large in size and transmit high power. They are common energy transmission devices in life. Cables can be divided into rigid cables and flexible cables according to their hardness.

[0003] After the cable is extended or broken, in order to make the remaining cable continue to be used, the two sections of the cable need to be connected to each other. In order to ensure that the power can be connected after the connection, the two sections of the cable core need to be welded, and after the welding is completed, a protective layer is put on the outside;

[0004] The cable core is generally thicker. When two sections of cable need to be welded, it is difficult to weld the cables with high quality using simple equipment, because general welding equipment is generally suitable for thinner wires, and there is no suitable welding equipment for thick cables. Summary of the invention

[0005] To this end, the technical problem to be solved by the present invention is to overcome the problem that the cable core of the cable in the prior art is generally thick. When two sections of cable need to be welded, it is difficult to weld the cable with high quality using simple equipment, because general welding equipment is generally suitable for thinner electric wires, and there is no suitable welding equipment for thick cables.

[0006] In order to solve the above technical problems, the present invention provides a composite flexible cable welding device, comprising two relatively arranged welding seats, the welding seat comprising a support seat, a welding frame and a driving ring are arranged on the top of the support seat, a driving assembly is arranged on the inner ring of the driving ring, and the driving assembly is used to drive the cable to move, an insertion hole is provided on the side of the welding frame close to the driving ring, and the side of the welding frame away from the driving ring is open, and a cable outlet is provided on one side of the welding frame, a welding table is fixedly connected to one side of the two welding seats, a hydraulic telescopic rod is fixedly connected to the side of the welding table close to the welding seat, a mechanical claw is fixedly connected to the output end of the hydraulic telescopic rod, and a plurality of welding nozzles are fixedly connected to the inner ring of the mechanical claw, a raw material box for providing raw materials to the welding nozzle is arranged inside the welding table, a transmission pipe is fixedly connected between the raw material box and the welding nozzle, and a docking groove is provided on the side of the welding frame close to the welding table. Through the arrangement of the two welding seats, the outer protective layers of the two cables to be welded are first removed, and then they are passed through the driving ring, and then Insert the cable into the welding frame, pull the cable toward the welding frame through the driving component in the driving ring, and as the cable heads at both ends touch in the welding frame, the hydraulic telescopic rod is started to extend, and the mechanical claw is extended into the two welding frames. The unfolded mechanical claw will frame the two sections of the cable core. As the mechanical claw closes, the two sections of the cable core are grasped. The inner ring diameter of the mechanical claw is larger than the outer diameter of the cable core. The two sections of the cable core are welded with multiple welding nozzles in the inner ring of the mechanical claw. Some welding nozzles are used to generate high temperature, and some welding nozzles provide welding tin liquid. The raw materials are provided by the raw material box and transmitted through the transmission pipe. Through this setting, the stable welding of the two sections of the cable core is achieved, and the annular welding method of the mechanical claw is used to ensure a comprehensive welding process. At the same time, the entire welding process does not require manual operation, reducing the operation steps. After completion, the cable is pushed out of the welding frame through the cable outlet through the continued extension of the hydraulic telescopic rod. The side of the driving ring close to the cable outlet is a rotation setting, which can be opened so that the welded cable can be smoothly removed after welding.

[0007] In one embodiment of the present invention, a horizontally arranged separation plate is fixedly connected to the inner side of the welding frame, and the separation plate is located in a lower middle position of the welding frame. Two hydraulic rods are fixedly connected to the top of the welding frame, and a translation guide rail is fixedly connected between the bottom output ends of the two hydraulic rods. A connecting plate is slidably connected to the inner side of the translation guide rail, and a lower pressure plate is fixedly connected to the bottom of the connecting plate. A translation module is arranged between the connecting plate and the translation guide rail, and the translation module is used to drive the connecting plate to slide back and forth in the translation guide rail. When the cable penetrates into the welding frame, the hydraulic rod is started to drive the translation guide rail and the lower pressure plate to sink, so that the lower pressure plate presses the cable core to the position of the separation plate, and then the connecting plate and the lower pressure plate are driven by the translation module to move. Moving horizontally, the cable core is made up of multiple strands of flexible wires, which will be spread out horizontally under the squeezing movement. By setting the heights of the two separation plates at different levels, the flattened wires at both ends will diverge from each other. As the driving assembly continues to transport the cable inward, the flattened cable cores at both ends will overlap up and down. At this time, as the open mechanical claw moves from left to right, the flattened cable core can be gathered into the mechanical claw. The inner circle of the mechanical claw is circular. After gathering and gripping, the mechanical claw is released for a certain distance to allow the cable core to remain in the middle of the mechanical claw for welding. Through this setting, the two sections of cable cores can overlap each other. Compared with simple end welding, the docking can be more stable, further improving the welding quality.

[0008] In one embodiment of the present invention, a plurality of spherical protrusions are fixedly connected to the top surface of the separation plate, a plurality of movable grooves are opened inside the lower pressure plate, the bottom of the movable groove passes through the bottom surface of the lower pressure plate, and movable balls are arranged on the inner side of the movable groove. The movable groove is spherical, and the inner diameter of the movable groove is larger than the inner diameter of the movable ball. The arrangement of the protrusions and movable balls on the top surface of the separation plate increases the friction force when separating the cable core, so that the cable core is subjected to stronger force during the friction process and can be dispersed more thoroughly. The spherical arrangement makes the force uniform and will not excessively damage the cable core during the extrusion process.

[0009] In one embodiment of the present invention, the top of the movable groove passes through the top of the lower pressure plate, the top of the movable ball is fixedly connected with a connecting piece of elastic material, and the top of the connecting piece is fixedly connected with a counterweight ball. During the shaking of the lower pressure plate, the counterweight ball will swing under the action of inertia, and the swinging vibration will be transmitted to the movable ball through the elastic connecting piece, so that the movable ball can vibrate at a high frequency, further enhancing the effect of dispersing the cable core.

[0010] In one embodiment of the present invention, three electric telescopic rods are fixedly connected to the inner wall of the welding frame at equal intervals in the horizontal direction, wherein two electric telescopic rods are fixedly connected at the top and one electric telescopic rod is fixedly connected at the bottom in one welding seat; two electric telescopic rods are fixedly connected at the bottom and one electric telescopic rod is fixedly connected at the top in another welding seat. After the cable core is dispersed, the three electric telescopic rods are started to extend, and the extended three electric telescopic rods will contact the cable core that has been frictionally spread out. With the upper and lower distribution of the three electric telescopic rods, the spread out cable core can be pushed into a three-petal unfolded state, and due to the different distribution of the electric telescopic rods in the two welding frames, the two sections of the cable core will be pushed into three-petal shapes with different structures. When the two cable cores are close to each other, the cable cores with different shapes can adapt to each other and snap together, and then gather and form under the claws and bottom of the mechanical claws, and then weld. In this way, the fusion degree of the two cable cores is further improved, thereby effectively improving the welding quality.

[0011] In one embodiment of the present invention, the electric telescopic rod 1 is arranged in an inclined shape, and the inclined direction is toward the direction of the circular separation plate. The output end of the electric telescopic rod 1 is fixedly connected to a top plate, and the top plate is arranged in a flat shape. With the arrangement of the top plate, the cable core can be better and more evenly stressed during the opening process, so that the docking process of the two cable cores is smoother. The inclined arrangement of the electric telescopic rod 1 is also to make the stress process of the cable core more uniform.

[0012] In one embodiment of the present invention, the driving assembly includes an electric telescopic rod 2, which is fixedly connected to the top of the inner ring of the driving ring. An electric wheel is fixedly connected to the bottom of the output end of the electric telescopic rod 2. The inner ring of the driving ring is rotatably connected to a plurality of rotating balls. Through the rotation of the electric wheel, force is applied to the surface of the cable, thereby controlling the cable to move in the direction of the welding frame. At the same time, the setting of the rotating ball can reduce the friction between other parts of the cable and the driving ring, and the electric telescopic rod 2 can adjust the height of the electric wheel to adapt to cables of various specifications.

[0013] In one embodiment of the present invention, a chuck is fixedly connected to one end of the welding frame close to the driving ring, and the end of the chuck close to the cable outlet is open. The open end of the chuck is rotatably connected to a disengagement block. A moving module is connected between the welding frame and the support seat, and the moving module is used to drive the welding frame to move. In the final cable welding stage, after the cable is flattened, the cable needs to be transported forward for a distance to allow the two sections of the cable to dock. However, the cable is generally thicker and longer, and is frequently moved, which is easy to affect nearby staff. Through the setting of the chuck, during the early fixing process, a sufficient length of cable is transported toward the welding frame through the driving ring. After the cable is transported to a distance above the separation plate, the cable is first clamped by the chuck, and the excess cable is first stored between the welding frame and the driving ring. After that, the electric wheel no longer moves. When the two sections of the cable need to be docked, the two welding frames are driven close to each other by the moving module to complete the cable docking. Through this setting, the external cable will only move before processing, and will not suddenly pull the external cable during processing, causing the problem of tripping the staff. The rotation connection of the disengagement block allows the cable that has been welded later to be normally disengaged.

[0014] In one embodiment of the present invention, a slide groove is provided between the driving ring and the welding frame, a screw nut mechanism is fixedly connected in the slide groove, a nut moving end of the screw nut mechanism is slidably engaged with the slide groove, and a bending arm is fixedly connected to the top of the nut moving end, and the bending arm is driven to move by the screw nut mechanism, so that the cable temporarily stored between the driving ring and the welding frame can be straightened and deflected to one side. Through this arrangement, the temporarily stored cable will not be twisted or loose, and subsequent extension is convenient.

[0015] In one embodiment of the present invention, a composite flexible cable is welded by the composite flexible cable welding equipment described above, comprising a plurality of flexible conductive threads, an insulating layer is sleeved on the outer side of the plurality of flexible conductive threads, a wrapping tape is sleeved on the outer side of the insulating layer, a shielding layer is sleeved on the outer side of the wrapping tape, a sheath layer is sleeved on the outer side of the shielding layer, and an outer sheath is sleeved on the outer side of the sheath layer. The plurality of flexible conductive threads can not only transmit electricity normally, but also bend to a certain extent and will not break easily, thereby improving the service life of the cable. At the same time, an insulating layer for isolating electricity and a shielding layer for shielding electromagnetics are provided on the outer side, thereby improving the safety of use, and the wrapping tape and the sheath layer can well protect the internal structure.

[0016] The above technical solution of the present invention has the following advantages compared with the prior art:

[0017] The composite flexible cable welding device described in the present invention, through the arrangement of two welding seats, pulls the cable to move in the direction of the welding frame through the driving assembly in the driving ring, and as the cable heads at both ends contact in the welding frame, the unfolded mechanical claws will frame the two sections of the cable core, and as the mechanical claws close, the two sections of the cable core are grasped, the inner ring diameter of the mechanical claws is larger than the outer diameter of the cable core, and the two sections of the cable core are welded in conjunction with multiple welding nozzles in the inner ring of the mechanical claws, some of the welding nozzles are used to generate high temperature, and some of the welding nozzles provide welding tin liquid, and the raw materials are provided by the raw material box and transmitted through the transmission pipe. Through this arrangement, the work of stably welding the two sections of the cable core is realized, and the annular welding method of the mechanical claws is combined to ensure a comprehensive welding process, and at the same time, the entire welding process does not require manual operation, thereby reducing the operation steps;

[0018] When the cable goes deep into the welding frame, the hydraulic rod is started to drive the translation guide rail and the lower pressure plate to sink, so that the lower pressure plate presses the cable core to the position of the separation plate, and then the connecting plate and the lower pressure plate are driven to move horizontally through the translation module. The cable core is formed by multiple strands of flexible wires gathered together, and will be spread horizontally under the extrusion movement. By setting the heights of the two separation plates at different levels, the flattened wires at both ends will diverge from each other. As the drive assembly continues to transport the cable inward, the flattened cable cores at both ends will overlap up and down. At this time, as the open mechanical claw moves from left to right, the flattened cable core can be gathered into the mechanical claw. The inner circle of the mechanical claw is circular. After gathering and gripping, the mechanical claw is loosened for a certain distance to allow the cable core to remain in the middle of the mechanical claw for welding. Through this setting, the two sections of cable cores can overlap each other. Compared with simple end welding, the docking can be more stable, further improving the welding quality.

DETAILED DESCRIPTION

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1 , Figure 2 and Figure 7 As shown, a composite flexible cable welding device of the present invention comprises two relatively arranged welding seats 1, the welding seat 1 comprises a supporting seat 5, a welding frame 4 and a driving ring 6 are arranged on the top of the supporting seat 5, a driving assembly is arranged on the inner ring of the driving ring 6, and the driving assembly is used to drive the cable to move, an insertion hole is provided on the side of the welding frame 4 close to the driving ring 6, and the side of the welding frame 4 away from the driving ring 6 is open, and a cable outlet 7 is provided on one side of the welding frame 4, a welding platform 2 is fixedly connected to one side of the two welding seats 1, a hydraulic telescopic rod 26 is fixedly connected to the side of the welding platform 2 close to the welding seat 1, a mechanical claw 27 is fixedly connected to the output end of the hydraulic telescopic rod 26, and a plurality of welding nozzles are fixedly connected to the inner ring of the mechanical claw 27, a raw material box for providing raw materials to the welding nozzle is arranged inside the welding platform 2, a transmission pipe is fixedly connected between the raw material box and the welding nozzle, and a docking groove 10 is provided on the side of the welding frame 4 close to the welding platform 2;

[0031] During operation, the cable core is generally thicker. When two sections of cable need to be welded, it is difficult to weld the cable with high quality using simple equipment, because general welding equipment is generally suitable for thinner wires, and there is no suitable welding equipment for thick cables.

[0032] Through the setting of two welding seats 1, the outer protective layers of the two cables to be welded are first removed, and then they are passed through the drive ring 6 and inserted into the welding frame 4. The drive assembly in the drive ring 6 pulls the cable to move in the direction of the welding frame 4. As the cable heads at both ends touch in the welding frame 4, the hydraulic telescopic rod 26 is started to extend, and the mechanical claw 27 is extended into the two welding frames 4. The unfolded mechanical claw 27 will frame the two sections of the cable core. As the mechanical claw 27 closes, the two sections of the cable core are grasped. The inner ring diameter of the mechanical claw 27 is larger than the outer diameter of the cable core. With the multiple welding nozzles on the inner ring of the mechanical claw 27, the two sections of the cable core are welded. The cable core is welded, some welding nozzles are used to generate high temperature, and some welding nozzles provide welding tin liquid. The raw materials are provided by the raw material box and transmitted through the transmission pipe. Through this setting, the stable welding of the two sections of the cable core is achieved, and the annular welding method of the mechanical claw 27 is used to ensure a comprehensive welding process. At the same time, the entire welding process does not require manual operation, which reduces the operation steps. After completion, the hydraulic telescopic rod 26 is continued to extend to push the cable out of the welding frame 4 through the cable outlet 7. The side of the driving ring 6 close to the cable outlet 7 is rotatable and can be opened to allow the welded cable to be smoothly removed after welding.

[0033] Reference Figures 3 to 6 As shown, a horizontally arranged separation plate 12 is fixedly connected to the inner side of the welding frame 4, and the separation plate 12 is located at a position slightly lower than the middle of the welding frame 4. Two hydraulic rods 3 are fixedly connected to the top of the welding frame 4, and a translation guide rail 24 is fixedly connected between the bottom output ends of the two hydraulic rods 3. A connecting plate is slidably connected to the inner side of the translation guide rail 24, and a lower pressure plate 20 is fixedly connected to the bottom of the connecting plate. A translation module is arranged between the connecting plate and the translation guide rail 24, and the translation module is used to drive the connecting plate to slide back and forth in the translation guide rail 24;

[0034] During operation, after the cable penetrates into the welding frame 4, the hydraulic rod 3 is started to drive the translation guide rail 24 and the lower pressure plate 20 to sink, so that the lower pressure plate 20 presses the cable core to the position of the separation plate 12, and then the connecting plate and the lower pressure plate 20 are driven by the translation module to move horizontally. The cable core is formed by gathering multiple strands of flexible wires. Under the extrusion movement, it will be spread horizontally. By setting the heights of the two separation plates 12 differently, the flattened wires at both ends will diverge from each other. As the driving component continues to transport the cable inward, the flattened cable cores at both ends will overlap up and down. At this time, as the opened mechanical claw 27 moves from left to right, the flattened cable core can be gathered into the mechanical claw 27. The inner circle of the mechanical claw 27 is circular. After gathering and gripping, the mechanical claw 27 is loosened for a certain distance, so that the cable core is maintained in the middle of the mechanical claw 27 for welding. Through this setting, the two sections of the cable core can overlap each other. Compared with simple end welding, the docking can be more stable, further improving the welding quality.

[0035] Reference Figures 4 to 6 As shown, a plurality of spherical protrusions are fixedly connected to the top surface of the separation plate 12, and a plurality of movable grooves 22 are opened inside the lower pressure plate 20. The bottom of the movable groove 22 passes through the bottom surface of the lower pressure plate 20, and an movable ball 21 is arranged on the inner side of the movable groove 22. The movable groove 22 is arranged in a spherical shape, and the inner diameter of the movable groove 22 is larger than the inner diameter of the movable ball 21. When working, the setting of the protrusions and movable balls 21 on the top surface of the separation plate 12 increases the friction force when separating the cable core, so that the cable core is subjected to stronger force during the friction process and can be dispersed more thoroughly, and the spherical setting makes it evenly stressed and will not excessively damage the cable core during the extrusion process.

[0036] Reference Figure 6 As shown, the top of the movable groove 22 passes through the top of the lower pressure plate 20, and the top of the movable ball 21 is fixedly connected with a connecting piece 25 of elastic material, and the top of the connecting piece 25 is fixedly connected with a counterweight ball 23. During operation, when the lower pressure plate 20 shakes, the counterweight ball 23 will swing under the action of inertia, and the swinging vibration will be transmitted to the movable ball 21 through the elastic connecting piece 25, so that the movable ball 21 can vibrate at a high frequency, further enhancing the effect of dispersing the cable core.

[0037] Reference Figures 3 to 5 As shown, three electric telescopic rods 13 are fixedly connected to the inner wall of the welding frame 4 at equal intervals in the horizontal direction, wherein two electric telescopic rods 13 are fixedly connected to the upper part of one welding seat 1, and one electric telescopic rod 13 is fixedly connected to the lower part; two electric telescopic rods 13 are fixedly connected to the lower part of another welding seat 1, and one electric telescopic rod 13 is fixedly connected to the upper part;

[0038] During operation, after the cable core is dispersed, the three electric telescopic rods 13 are started to extend. The extended three electric telescopic rods 13 will contact the cable core that has been spread out by friction. With the upper and lower distribution of the three electric telescopic rods 13, the spread cable core can be pushed into a three-petal unfolded state. Moreover, due to the different distribution of the electric telescopic rods 13 in the two welding frames 4, the two sections of the cable core will be pushed into three-petal shapes with different structures. When the two cable cores are close to each other, the cable cores of different shapes can adapt to each other and snap together. Then, they are gathered together under the claws of the mechanical claws 27 and welded. In this way, the fusion degree of the two cable cores is further improved, thereby effectively improving the welding quality.

[0039] Reference Figures 3 to 5As shown, the electric telescopic rod 13 is arranged in an inclined shape, and the inclined direction is toward the direction of the circular separation plate 12. The output end of the electric telescopic rod 13 is fixedly connected with a top plate 14, and the top plate 14 is arranged in a flat shape. When working, the setting of the top plate 14 is combined with the setting of the top plate 14, so that the cable core can be better and more evenly stressed during the opening process, so that the docking process of the two cable cores is smoother, and the inclined setting of the electric telescopic rod 13 is also to make the stress process of the cable core more uniform.

[0040] Reference Figure 4 As shown, the driving assembly includes an electric telescopic rod 17, which is fixedly connected to the top of the inner ring of the driving ring 6. An electric wheel 18 is fixedly connected to the bottom of the output end of the electric telescopic rod 17. The inner ring of the driving ring 6 is rotatably connected to multiple rotating balls 19. When working, the rotation of the electric wheel 18 applies force to the surface of the cable, so that the cable can be controlled to move in the direction of the welding frame 4. At the same time, the setting of the rotating ball 19 can reduce the friction between other parts of the cable and the driving ring 6, and the electric telescopic rod 17 can adjust the height of the electric wheel 18 to adapt to cables of various specifications.

[0041] Reference Figures 1 to 3 As shown, the end of the welding frame 4 close to the driving ring 6 is fixedly connected with a clamp 8, and the end of the clamp 8 close to the cable outlet 7 is open, and the open end of the clamp 8 is rotatably connected with a disengagement block 9. A moving module is connected between the welding frame 4 and the support seat 5, and the moving module is used to drive the welding frame 4 to move. During work, in the final cable welding stage, after the cable is flattened, it is necessary to transport the cable forward for a distance so that the two sections of the cable can be butt-jointed. However, the cable is generally thicker and longer, and is frequently moved, which is easy to affect nearby staff. Through the setting of the clamp 8, during the early fixing process, the driving The dynamic ring 6 transports a sufficient length of cable toward the welding frame 4. After the cable is transported to a certain distance above the separation plate 12, the cable is clamped by the chuck 8, and the excess cable is first stored between the welding frame 4 and the driving ring 6. After that, the electric wheel 18 no longer moves. When the two sections of cable need to be docked, the two welding frames 4 are driven closer to each other by the moving module to complete the cable docking. Through this setting, the external cable will only move before processing, and will not be suddenly pulled during the processing, causing the problem of tripping the staff. The rotating connection of the disengagement block 9 allows the cable that has been welded later to be normally disengaged.

[0042] Reference Figure 3 to Figure 4As shown, a slide groove is provided between the driving ring 6 and the welding frame 4, and a screw nut mechanism 15 is fixedly connected in the slide groove. The nut moving end of the screw nut mechanism 15 is slidably engaged with the slide groove, and a bending arm 16 is fixedly connected to the top of the nut moving end. When working, the bending arm 16 is driven to move by the screw nut mechanism 15, so that the cable temporarily stored between the driving ring 6 and the welding frame 4 can be straightened and deflected to one side. Through this arrangement, the temporarily stored cable will not be twisted or loose, which is convenient for subsequent stretching.

[0043] Reference Figure 8 As shown, a composite flexible cable is welded by the composite flexible cable welding equipment described above, including multiple strands of flexible conductive wires 28, the outer side of the multiple strands of the flexible conductive wires 28 is sleeved with an insulating layer 29, the outer side of the insulating layer 29 is sleeved with a wrapping tape 32, the outer side of the wrapping tape 32 is sleeved with a shielding layer 30, the outer side of the shielding layer 30 is sleeved with a sheath layer 31, and the outer side of the sheath layer 31 is sleeved with an outer sheath 33. When working, the multiple strands of flexible conductive wires 28 can not only transmit electricity normally, but also bend to a certain extent and will not break easily, thereby improving the service life of the cable. At the same time, an insulating layer 29 for isolating electricity and a shielding layer 30 for shielding electromagnetics are provided on the outside, thereby improving the safety of use, and the wrapping tape 32 and the sheath layer 31 can well protect the internal structure.

[0044] During operation, through the setting of two welding seats 1, the outer protective layers of the two cables to be welded are first removed, and then they are passed through the drive ring 6 and inserted into the welding frame 4. The drive assembly in the drive ring 6 pulls the cable to move in the direction of the welding frame 4. As the cable heads at both ends touch in the welding frame 4, the hydraulic telescopic rod 26 is started to extend, and the mechanical claw 27 is extended into the two welding frames 4. The unfolded mechanical claw 27 will frame the two sections of the cable core. As the mechanical claw 27 closes, the two sections of the cable core are grasped. The inner ring diameter of the mechanical claw 27 is larger than the outer diameter of the cable core. With the multiple welding nozzles on the inner ring of the mechanical claw 27, the two sections of the cable core are welded. The cable core of the two sections is welded, some welding nozzles are used to generate high temperature, and some welding nozzles provide welding tin liquid. The raw materials are provided by the raw material box and transmitted through the transmission pipe. Through this setting, the work of stably welding the two sections of the cable core is realized, and the annular welding method of the mechanical claw 27 is used to ensure a comprehensive welding process. At the same time, the entire welding process does not require manual operation, which reduces the operation steps. After completion, the cable is pushed out of the welding frame 4 through the cable outlet 7 through the continued extension of the hydraulic telescopic rod 26. The side of the driving ring 6 close to the cable outlet 7 is a rotation setting, which can be opened so that the welded cable can be smoothly removed after the welding is completed;

[0045] When the cable penetrates into the welding frame 4, the hydraulic rod 3 is started to drive the translation guide rail 24 and the lower pressure plate 20 to sink, so that the lower pressure plate 20 presses the cable core to the position of the separation plate 12, and then the connection plate and the lower pressure plate 20 are driven by the translation module to move horizontally. The cable core is formed by gathering multiple strands of flexible wires. Under the extrusion movement, it will be spread horizontally. By setting the heights of the two separation plates 12 differently, the flattened wires at both ends will diverge from each other. As the driving component continues to transport the cable inward, the flattened cable cores at both ends will overlap up and down. At this time, as the opened mechanical claw 27 moves from left to right, the flattened cable core can be gathered into the mechanical claw 27. The inner circle of the mechanical claw 27 is circular. After gathering and gripping, the mechanical claw 27 is loosened for a certain distance, so that the cable core is maintained in the middle of the mechanical claw 27 for welding. Through this setting, the two sections of the cable core can overlap each other. Compared with simple end welding, the docking can be more stable, which further improves the welding quality.

[0046] The arrangement of the protruding movable ball 21 on the top surface of the separation plate 12 increases the friction force when separating the cable core, so that the cable core is subjected to stronger force during the friction process and can be dispersed more thoroughly. The spherical arrangement makes the force uniform and will not excessively damage the cable core during the extrusion process.

[0047] During the shaking process of the lower pressure plate 20, the weight ball 23 will swing under the action of inertia, and the vibration of the swing will be transmitted to the movable ball 21 through the elastic connecting piece 25, so that the movable ball 21 can vibrate at a high frequency, further enhancing the effect of dispersing the cable core;

[0048] After the cable core is dispersed, the three electric telescopic rods 13 are started to extend. The three electric telescopic rods 13 extend and contact the cable core that has been spread out by friction. With the upper and lower distribution of the three electric telescopic rods 13, the spread cable core can be pushed into a three-petal unfolded state. Since the electric telescopic rods 13 in the two welding frames 4 are distributed differently, the two sections of the cable core will be pushed into three-petal shapes with different structures. When the two cable cores are close to each other, the cable cores with different shapes can be adapted to each other and snap together. Then, they are gathered together under the claws and bottom of the mechanical claws 27 and welded. In this way, the fusion degree of the two cable cores is further improved, thereby effectively improving the welding quality.

[0049] With the setting of the top plate 14, the cable core can be better and more evenly stressed during the top opening process, making the docking process of the two cable cores smoother, and the inclined setting of the electric telescopic rod 13 is also to make the stress process of the cable core more even;

[0050] By rotating the electric wheel 18, the force is applied to the surface of the cable, so that the cable can be controlled to move in the direction of the welding frame 4. At the same time, the setting of the rotating ball 19 can reduce the friction between other parts of the cable and the driving ring 6, and the electric telescopic rod 17 can adjust the height of the electric wheel 18 to adapt to cables of various specifications.

[0051] In the final cable welding stage, after the cable is flattened, it is necessary to transport the cable forward for a distance so that the two sections of the cable can be connected. However, the cable is generally thicker and longer, and is frequently moved, which can easily affect nearby workers. Through the setting of the clamp 8, during the early fixing process, a sufficient length of cable is transported toward the welding frame 4 through the drive ring 6. After the cable is transported to a distance above the separation plate 12, the cable is first clamped by the clamp 8, and the excess cable is first stored between the welding frame 4 and the drive ring 6. After that, the electric wheel 18 no longer moves. When the two sections of the cable need to be connected, the two welding frames 4 are driven to approach each other by the moving module to complete the cable connection. Through this setting, the external cable will only move before processing, and will not be suddenly pulled during processing, causing the problem of tripping the workers. The rotation connection of the disengagement block 9 allows the cable that has been welded later to be normally disengaged;

[0052] The bending arm 16 is driven to move by the screw nut mechanism 15, so that the cable temporarily stored between the drive ring 6 and the welding frame 4 can be straightened and deflected to one side. Through this arrangement, the temporarily stored cable will not be twisted or loose, which is convenient for subsequent stretching.

[0053] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
