Description

Technical Field

[0001] This invention belongs to the field of wire processing technology, and specifically discloses a copper-nickel twisted pair processing device. Background Technology

[0002] As carriers of electrical energy and signals, the performance of cables directly determines the reliability of electronic power systems. From large-section, high-voltage cross-linked polyethylene insulated power cables to micro-diameter, high-precision special electronic cables, despite the different application scenarios and performance requirements, achieving high-efficiency and high-quality processing and effectively controlling process defects such as insulation defects, conductor oxidation, and weld slag residue are common technical challenges faced by the industry. As consumer electronics, medical devices, and precision sensors evolve towards miniaturization and high reliability, the diameter of the metal wires used internally is becoming increasingly smaller (typically less than 0.1 mm). Twisted-pair cables, composed of copper and nickel wires, are widely used due to their combination of copper's excellent conductivity and nickel's corrosion resistance and high strength. After terminal soldering (such as in a soldering bath), high-temperature solder dross adheres to the surface of these fine-diameter twisted-pair cables. Due to the different behaviors of copper and nickel in molten solder, copper dissolves rapidly and forms a brittle copper-tin intermetallic compound, while nickel may form a nickel-tin compound, causing the resulting solder dross to adhere to the outer surface of the twisted wires. If not completely removed, this will lead to a decrease in insulation resistance, deterioration of signal transmission quality, and a risk of short circuits during subsequent use, severely restricting the yield and long-term reliability of high-end precision electronic products. Because copper wire is relatively fragile and the soldering process generates a certain temperature, the traditional method involves manually holding a flexible tool and gently scraping the outer surface of the stranded wire to remove the solder slag. However, the removed solder slag remains outside the solder bath and requires secondary processing, which complicates the process and necessitates an improvement. Summary of the Invention

Two sets of wire guide holes are provided on the top of the liquid storage tank, and a guide wheel frame is provided on the upper surface of the stranding platform and between the wire take-up mechanism. Compared with the prior art, the present invention has the following beneficial effects: 1. By setting two sets of tensioning frames between the wire feeding mechanism and the wire take-up mechanism, the copper wire and nickel wire can be stably pressed together by the cooperation of the sliding rod and sliding wheel in the tensioning frame. At the same time, combined with the rolling wheel above, the tension of the wire is effectively guaranteed during the wire feeding process, avoiding problems such as slack and deviation. This provides a stable wire foundation for subsequent stranding processing and improves stranding accuracy. The coordinated setting of the stranding rotary table and the wire-stopping mechanism allows the copper wire and nickel wire to be accurately stranded under the concentric cooperation of the wire-threading drum and the rotating cylinder wire-stopping drum. The telescopic cylinder and the limit wheel in the wire-stopping mechanism interact to limit and tighten the wire in real time during the stranding process, ensuring the stability of the stranding process, reducing stranding deviation, and thus improving the stranding quality of copper-nickel twisted wire, meeting the requirements of precision electronic products for wire structural stability. 2. The rolling blowing mechanism inside the conductor frame is driven by a second motor and gear transmission, which drives the C-shaped tube and flexible contact to rotate. The irregularly shaped rotating blades made of high-temperature resistant flexible material can flexibly wipe the surface of the twisted pair after soldering without damaging the wire. At the same time, the booster fan and pulse nozzle spray pulse airflow to achieve efficient removal of solder slag. Then, the solder slag is promptly extracted and collected through the suction pipe and the outer pipe, eliminating the need for secondary processing. This greatly improves the efficiency of solder slag cleaning and avoids the impact of solder slag residue on the insulation performance and signal transmission quality of the wire. 3. The device has modules for wire feeding, tensioning, stranding, soldering, cleaning, and immersion coating arranged along the stranding table to form a continuous processing flow, which greatly reduces intermediate transfer and manual intervention, improves production efficiency, and ensures that the stranded wire is cleaned and protected in a timely manner after welding, thereby improving product consistency and reliability.

Detailed Implementation To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below. like Figures 1-11 The copper-nickel twisted-pair wire stranding processing device shown includes a stranding table 1, a control device 2, two wire feeding mechanisms 4, a wire take-up mechanism 5, a stranding rotary table 15, and a wire-stopping mechanism. The two wire feeding mechanisms 4 are disposed on the upper surface of one end of the stranding table 1, and the wire take-up mechanism 5 is disposed on the upper surface of the other end of the stranding table 1. Two sets of tensioning frames 9 are disposed between the wire feeding mechanisms 4 and the wire take-up mechanism 5. The bottoms of both tensioning frames 9 are fixedly mounted on the upper surface of the stranding table 1. A transition platform 11 is fixedly disposed on the upper surface of the stranding table 1 near the two sets of tensioning frames 9. The wire-stopping mechanism is disposed above the transition platform 11, near the upper surface of the stranding table 1 and close to the wire take-up mechanism 5. A support frame 7 is provided on one side, and a solder pot 13 for stranded wire soldering is placed on the upper surface of the stranding table 1. One end of the solder pot 13 is located inside the lower part of the support frame 7. The support frame 7 is connected to a heat transfer shell 22 through a sliding mechanism provided on the top wall. A lead wire wheel 21 is rotatably installed in the middle of the heat transfer shell 22. A wire frame 19 is provided on the upper end of the solder pot 13. Self-pulling wheels 32 are rotatably installed on both sides inside the wire frame 19. An installation shell 28 is provided on one side of the wire frame 19 and below the corresponding self-pulling wheel 32. A wire shell 30 is obliquely embedded in one end of the installation shell 28. A rolling blowing mechanism is provided inside the wire shell 30 and above one end. In this embodiment, the control device 2 is used to control the start and stop of each mechanism and adjust the operating parameters; the two wire feeding mechanisms 4 are used to set up the copper wire reel and the nickel wire reel, respectively; the wire taking-up mechanism 5 is used to take up the processed copper-nickel twisted pair wire; the two sets of tensioning frames 9 and the transition platform 11 are used for the transition and guidance of the wire. Specifically, copper and nickel wires are released by two separate wire feeding mechanisms 4, tensioned by a tensioning frame 9, and then conveyed to a transition table 11. Above the transition table 11, they are twisted together to form a twisted pair. The twisted pair continues to be conveyed to a storage tank 12 for pre-immersion treatment, and then soldered in a solder bath 13 below the support frame 7. After soldering, the twisted pair enters the wire housing 30 via a pulley 32 on the wire guide frame 19, where a rolling blower removes surface solder slag. Finally, guided by a guide wheel frame 6, it is wound up by a take-up mechanism 5, completing the entire processing flow. The control device 2 coordinates the operation of each mechanism to ensure a coordinated processing rhythm. Both sides of the tensioning frame 9 are vertically installed with slide rods 39. The two sets of slide rods 39 are vertically slidably connected with sliding wheels 31. The two sets of sliding wheels 31 are used to press against the passing nickel wire and copper wire respectively. Roller wheels are installed on both sides of the upper part of the tensioning frame 9. In this embodiment, the two sets of sliding wheels 31 correspond to the conveying paths of copper wire and nickel wire, respectively, and are used to press against the wires passing through; the upper sides of the tensioning frame 9 are equipped with rollers through brackets and shafts, and the wheel surface of the rollers is adapted to the wire conveying direction; Specifically, the copper wire and the nickel wire pass through the rollers at the top of the corresponding tensioning frame 9, and then pass under the sliding wheel 31. The sliding wheel 31 slides vertically along the slide bar 39 under its own weight, forming a continuous pressure on the copper or nickel wire below, ensuring that the wire maintains a stable tension during the conveying process, avoiding slack or overstretching, and providing a stable wire state for subsequent stranding processing. The rollers also assist in guiding and reducing friction between the wire and the tensioning frame 9. A support plate is provided on the upper surface of one end of the transition platform 11, and an installation plate 10 is provided on one side of the support plate. A scissor-type clamp 47 is provided on the outer wall of the installation plate 10. Two sets of wire pulleys 20 are provided on the upper surface of the support plate and on the side close to the installation plate 10. The two sets of wire pulleys 20 are arranged in an alternating manner. In this embodiment, the scissor clamp 47 is fixed to the outer wall of the mounting plate 10 by bolts. The clamping port of the scissor clamp 47 corresponds to the wire conveying path. The two sets of wire pulleys 20 are staggered and their grooves are used to accommodate and guide the wire. Specifically, the copper and nickel wires conveyed by the tensioning frame 9 pass through two sets of staggered wire pulleys 20. The staggered guidance allows the two wires to form a preset angle in advance, which is convenient for subsequent stranding on the stranding rotary table 15. When it is necessary to pause and adjust or to initially position the wires during the processing, the scissor-type clamp 47 is closed to accurately clamp and fix the wires, preventing wire displacement and ensuring processing accuracy and operational safety. The twisting rotary table 15 is located on the upper surface of the transition table 11 and near the middle. A threading tube is embedded in one end of the twisting rotary table 15. A rotary cylinder push-wire tube 18 is connected to one side of the twisting rotary table 15 through the installed first motor 3 and transmission assembly. The threading tube and the rotary cylinder push-wire tube 18 are aligned. In this embodiment, after being guided by the wire pulley 20, the copper wire and the nickel wire pass through the threading drum of the twisting rotary table 15 and enter the rotating cylinder wire-stopping drum 18. The control device 2 starts the first motor 3, which drives the rotating cylinder wire-stopping drum 18 to rotate through the transmission component. Since the threading drum and the rotating cylinder wire-stopping drum 18 are aligned, the two wires are evenly twisted into a twisted pair under the rotational driving force of the rotating cylinder wire-stopping drum 18, thus realizing the twisting of the wires. It should be noted that the transmission component is belt driven. The rotary cylinder wire-stopping cylinder 18 consists of four sets of cylinder bodies, a wire-stopping sleeve, and an elastic bushing. The telescopic ends of the four sets of cylinder bodies are fixedly connected to the elastic bushing, and the four sets of cylinder bodies are respectively embedded in the four sides of the wire-stopping sleeve. When the wire is stopped, the telescopic drive of the cylinder body causes the elastic bushing to fit tightly with the copper wire and nickel wire, and then rotates to complete the twisting. The line-stopping mechanism includes a mounting platform 8 fixedly installed on the upper surface of the transition platform 11 and near the side of the twisting rotating platform 15. A telescopic cylinder 16 is provided on the outside of the mounting platform 8. A ball is connected to the telescopic end of the telescopic cylinder 16. A limit wheel is rotatably installed inside the mounting platform 8 and near the lower part of the ball. A tensioning wheel group 14 is installed on the upper surface of the twisting platform 1 and near the end of the transition platform 11. In this embodiment, the ball surface is smooth and corresponds to the wire conveying path; a limit wheel is installed inside the mounting platform 8 near the ball via a rotating shaft, and the wheel surface of the limit wheel corresponds to the ball; the tension wheel assembly 14 is installed on the upper surface of the stranding platform 1 via a bracket and is located at one end near the transition platform 11. The tension wheel assembly 14 is composed of multiple pulleys and is adapted to the wire conveying path. Specifically, during the stranding process, the control device 2 controls the extension cylinder 16 to extend, and the ball bearing at the extension end cooperates with the limiting wheel inside the mounting platform 8 to limit and tighten the stranded wires from both the top and bottom ends, preventing the wires from shifting during stranding; at the same time, the tensioning wheel group 14 applies a continuous tension force to the stranded wires to ensure that the stranding pitch of the stranded wires is uniform and stable, improves the stranding quality, and ensures the smooth progress of the subsequent soldering process. The sliding mechanism includes a guide rail frame 23 fixedly installed on the top wall of the support frame 7. A guide rod 25 is slidably installed on one side inside the guide rail frame 23. A positioning pin 24 is threadedly connected to one end inside the guide rod 25. The end face of the positioning pin 24 abuts against the outer wall of one side of the guide rail frame 23. The bottom end of the guide rod 25 is connected to the upper end of the heat transfer shell 22. In this embodiment, according to the specifications of the twisted pair and the soldering requirements, the positioning screw 24 is loosened, and the guide rod 25 is pushed to slide along the slide groove of the guide rail frame 23, which drives the heat transfer shell 22 and the internal lead wheel 21 to move, adjust the position of the lead wheel 21, and thus change the depth of the twisted pair in the solder pot 13; after the adjustment is in place, the positioning screw 24 is tightened so that the end face of the positioning screw 24 abuts against the outer wall of the guide rail frame 23, fixes the position of the guide rod 25, and ensures the guiding stability of the lead wheel 21 during the soldering process; It should be noted that the heat transfer shell 22 is made of high-temperature resistant thermally conductive material, and an insulation layer can be added to the outer wall, while the interior is a hollow cavity. The rolling blowing mechanism includes two fixed plates 36, a C-shaped tube 37, and a suction tube 38. The two fixed plates 36 are respectively fixedly installed on both sides inside the mounting shell 28, and the side of the two fixed plates 36 that is close to each other is connected to the outer wall of the wire housing 30. A frame plate 33 is fixedly installed on the upper surface of one end of the wire housing 30. A second motor 34 is embedded inside the frame plate 33. A drive gear 17 is fixedly sleeved on the outside of the output shaft of the second motor 34. A ring sleeve 42 is fixedly sleeved on one end of the C-shaped tube 37. The wire housing 30 passes through the two sides of the inner wall installed with... The bearing bracket 45 is rotatably connected to the outside of the ring sleeve 42. A flexible contact is provided at one end of the ring sleeve 42. A booster fan 43 is embedded in one side of the C-shaped tube 37. Pulse nozzles 44 are installed at equal intervals along the horizontal direction inside the booster fan 43. The suction pipe 38 is connected to the lower side of the inside of the wire housing 30. An outer pipe 29 is connected to the end of the suction pipe 38 away from the wire housing 30. A gear 40 is fixedly sleeved on the outside of the C-shaped tube 37 and near the lower part of the ring sleeve 42. The gear 40 is meshed with the drive gear 17. In this embodiment, after the soldered twisted pair enters the conductor housing 30, the control device 2 starts the second motor 34. The second motor 34 drives the drive gear 17 to rotate, which in turn drives the C-shaped tube 37 and the flexible contact to rotate through the gear 40. The flexible contact contacts and wipes the surface of the twisted pair to remove the solder slag. At the same time, the booster fan 43 starts and sprays pulsed airflow through the pulse nozzle 44 to blow on the surface of the wire in a rotating motion trajectory. Since the shape of the solder slag is irregular, it can blow the solder slag on the surface of the wire at different angles as it follows the rotational motion. The solder slag blown off and scraped off is connected to an external negative pressure device through the external pipe 29 and works together with the suction pipe 38 to generate negative pressure, which draws the blown-off solder slag away from the conductor housing 30, achieving efficient cleaning of the solder slag. The flexible contact includes two connecting posts 46 symmetrically mounted on the outer wall of one side of the ring sleeve 42. The two connecting posts 46 are mounted together at the ends away from the ring sleeve 42. The inner wall of the ring sleeve 35 is equidistantly mounted with irregularly shaped spiral pieces 41 along the circumferential direction. A wire-passing channel is provided in the middle of the multiple irregularly shaped spiral pieces 41. The irregularly shaped spiral pieces 41 are made of a high-temperature resistant flexible material. In this embodiment, when the C-shaped tube 37 rotates, it drives the ring shell 35 and the internal irregularly shaped swivels 41 to rotate synchronously through the connecting post 46; the twisted pair passes through the wire channel between the multiple irregularly shaped swivels 41. Since the irregularly shaped swivels 41 are made of flexible material and rotate, their edges make flexible contact with the surface of the twisted pair. Without damaging the wire, the solder slag attached to the surface after being blown off is wiped off, improving the solder slag blowing effect. Together with the suction tube 38, the solder slag is thoroughly cleaned. It should be noted that the irregularly shaped rotary blade 41 is made of a sheet material composed of high-temperature resistant polytetrafluoroethylene composite material. A liquid storage tank 12 is provided on the upper end face of the stranding table 1 and between the support frame 7 and one of the tensioning frames 9. A through hole is provided on one side of the liquid storage tank 12, and a wire soaking wheel 26 is installed inside the through hole. Two sets of wire guide holes 27 are provided on the top of the liquid storage tank 12. A guide wheel frame 6 is provided on the upper end face of the stranding table 1 and between the wire take-up mechanism 5. In this embodiment, part of the immersion wheel 26 is immersed in the liquid in the storage tank 12; two sets of lead holes 27 are opened on the top of the storage tank 12, and the positions of the lead holes 27 correspond to the wheel surface of the immersion wheel 26 for threading and pulling the wire through. Specifically, the storage tank 12 is filled with flux or anti-oxidation liquid. The twisted pair of wires is inserted through a set of lead holes 27 on the top of the storage tank 12, passes around the surface of the dip wheel 26, and then exits through another set of lead holes 27. The dip wheel 26 causes the surface of the twisted pair of wires to be evenly coated with liquid, which plays a role in fluxing and preventing oxidation, thereby improving the firmness of subsequent soldering and the corrosion resistance of the wire. After the pre-dip and soldering and slag cleaning are completed, the twisted pair of wires is guided by the guide wheel of the guide wheel frame 6 and accurately conveyed to the take-up mechanism 5 to ensure a smooth take-up process and avoid wire tangling or deviation. Working principle: Copper wire reels and nickel wire reels are respectively installed on two wire feeding mechanisms 4. The free ends of the copper wire and nickel wire pass through the rolling wheels at the top of the corresponding tensioning frame 9, and then pass under the sliding wheel 31 on the slide rod 39 inside the tensioning frame 9. Under the action of gravity, the sliding wheel 31 slides vertically along the slide rod 39, forming a continuous and adaptive pressure on the copper wire and nickel wire, ensuring stable tension during wire feeding, avoiding slack or overstretching, and laying the foundation for subsequent processing; After initial tensioning, the copper and nickel wires pass through two sets of staggered wire pulleys 20 on the transition platform 11. The staggered guide design allows the two wires to form a preset angle in advance, facilitating subsequent twisting operations. The scissor-type clamps 47 on the outer wall of the mounting plate 10 can precisely clamp and fix the wires, ensuring operational safety and positioning accuracy during processing. The guided copper and nickel wires pass through the threading drum inside the twisting rotary table 15. The control device 2 starts the first motor 3, which drives the rotary cylinder to rotate the threading drum 18 through the transmission component. Since the threading drum and the rotary cylinder to the threading drum 18 are aligned, the two wires are evenly twisted under the rotation of the rotary cylinder to the threading drum 18. At the same time, the telescopic cylinder 16 in the wire-stopping mechanism extends, and the ball at its telescopic end cooperates with the limiting wheel inside the mounting platform 8 to limit and tighten the wire during the stranding process from the upper and lower sides to prevent the wire from deviating; the tensioning wheel group 14 on the stranding platform 1 simultaneously applies auxiliary tension force to the stranding wire to ensure that the stranding pitch is uniform and stable and improves the stranding quality. After being twisted, the twisted pair passes through the lead hole 27 at the top of the liquid storage tank 12, and then around the dipping wheel 26 inside the through hole of the liquid storage tank 12. The liquid storage tank 12 can be filled with flux or anti-oxidation liquid. The dipping wheel 26 causes the surface of the twisted pair to be evenly coated with liquid, which serves to assist soldering and prevent oxidation. The pre-dipped twisted pair continues to be transported to the solder pot 13 below the support frame 7, where the high temperature of the solder pot 13 achieves the soldering treatment of the twisted pair ends. The sliding mechanism on the top wall of the support frame 7 can move the heat transfer shell 22 and the lead wheel 21 inside by adjusting the position of the guide rod 25 in the guide rail frame 23. The positioning pin 24 is used to fix the position of the guide rod 25, thereby adjusting the soldering angle and depth of the twisted pair in the solder pot 13 to adapt to different soldering requirements. After soldering, the twisted pair wires are guided by the pulleys 32 on both sides inside the wire frame 19 and enter the inclined wire housing 30 inside the mounting housing 28. The control device 2 starts the second motor 34, and the drive gear 17 of the output shaft of the second motor 34 drives the meshing gear 40 to rotate. The gear 40 drives the C-shaped tube 37 and the ring sleeve 42 to rotate inside the wire housing 30 through the bearing bracket 45. The ring sleeve 42 rotates synchronously with the ring housing 35 connected by the connecting post 46. The irregularly shaped rotating blades 41 on the inner wall of the ring housing 35 make flexible contact with the surface of the twisted pair wires and wipe away the solder dross that has not been blown away during the rotation. At the same time, the booster fan 43 inside the C-shaped tube 37 starts, and pulse airflow is sprayed onto the surface of the twisted pair through pulse air nozzles 44 distributed at equal intervals along the horizontal direction. The newly attached solder slag is blown away in a circular rotation motion of forward and reverse. At this time, the fallen solder slag falls into the lower part of the conductor shell 30. The suction pipe 38 in the lower part of the conductor shell 30 is connected to the external negative pressure equipment through the external pipe 29 to extract and collect the blown solder slag in time, so as to avoid solder slag residue or scattering, and no secondary treatment is required. After the copper-nickel twisted pair wires have been cleaned of welding slag, they are guided by the guide wheel frame 6 and then connected to the take-up mechanism 5. The control device 2 adjusts the take-up speed of the take-up mechanism 5 to match the pay-off speed of the pay-off mechanism 4 and the rotation speed of the twisting rotary table 15, ensuring that the line speed of the entire processing process is synchronized. Finally, the processed copper-nickel twisted pair wires are neatly wound up, completing all processing steps.
