Description

Technical Field

[0001] This utility model relates to the field of tin-plated copper-clad steel wire production technology, specifically a welding aid device for tin-plated copper-clad steel wire. Background Technology

[0002] Tinned copper-clad steel wire (CP wire) is a type of material made from high-quality carbon steel core, uniformly coated with oxygen-free copper using mechanical methods, and then plated with pure tin. The production process involves eight steps: forming, drawing, annealing, electroplating, polishing, cleaning, soldering, and tinning. During soldering, tin-plated flux is applied to the outer surface of the copper wire; therefore, a soldering device is used to complete the soldering process.

[0003] Patent document CN211771509U discloses a hot-dip tin-plated copper-clad steel wire soldering device, including a soldering pool. Several inlet holes are provided on one side of the soldering pool, and a support frame is welded to the other side. The support frame has mounting holes, and a positioning sleeve is detachably connected to each mounting hole. A through hole is provided inside the positioning sleeve. A positioning plate is provided on the outlet side of the positioning sleeve and is mounted on the support frame with screws. A positioning hole is provided on the positioning plate, the diameter of which is smaller than the diameter of the positioning sleeve. A motor is installed at the bottom of the soldering pool, and the output shaft of the motor passes through the bottom of the soldering pool and is connected to a stirring blade.

[0004] The aforementioned fluxing device still has some problems in use. The device uses a wire structure to allow the copper-clad steel wire to pass through the flux-filled solder bath, ensuring the flux covers the outside of the wire for easy processing. However, the wire structure, with the aid of rollers, causes the copper-clad steel wire to bend. When passing the positioning sleeve, the lower part of the wire rubs severely against the sleeve, resulting in scraping and uneven flux application. Therefore, a fluxing device for tin-plated copper-clad steel wire is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the fluxing device uses a wire structure to allow the copper-clad steel wire to pass through the flux-filled flux pool, so that the flux covers the outside of the copper-clad steel wire, which facilitates processing. However, the wire structure uses rollers to make the copper-clad steel wire bend, and when it passes the positioning sleeve, the lower part of the copper-clad steel wire rubs severely with the positioning sleeve, resulting in scraping problems and uneven flux distribution. This utility model proposes a fluxing device for tin-plated copper-clad steel wire.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The welding device for tin-plated copper-clad steel wire of this utility model includes a welding pool, a guide roller is movably connected to the front end of the welding pool, and a pair of support frames and a support plate are fixedly connected to the rear end of the welding pool. A fixed pipe is fixedly connected to the lower end of the support frame, and a set of guide sleeves are equidistantly arranged directly below the fixed pipe. A transmission mechanism is provided at the front end of the guide sleeve. The fixed tube has a conveying groove inside, and a limiting sleeve is provided in the center of the opposite face of the fixed tube and the guide sleeve. The guide sleeve has a pair of discharge holes inside.

[0007] Preferably, the transmission mechanism includes a drive motor fixedly connected to the top surface of the support frame, a drive gear fixedly connected to the output end of the drive motor, a driven gear sleeve provided directly below the drive gear, and a transmission belt sleeved on the outer side of the opposite surfaces of the drive gear and the driven gear sleeve.

[0008] Preferably, the flux pool is filled with flux, and a delivery pump and a hot air blower are fixedly connected to one side of the flux pool. The input end of the delivery pump is fixedly connected to the flux pool, and the output end of the delivery pump is fixedly connected to the front fixed pipe of the two fixed pipes. The output end of the hot air blower is fixedly connected to the other fixed pipe.

[0009] Preferably, the guide roller has a set of guide grooves on its surface, and a set of positioning sleeves are fixedly connected at equal intervals inside the support plate. The positioning sleeves have shaping grooves inside, and the shaping grooves are located on the same axis as the two adjacent guide sleeves and the guide grooves on the surface of the guide roller.

[0010] Preferably, the upper end of the limiting sleeve is fixedly connected to the fixed pipe, and the limiting sleeve is connected through the conveying groove. The lower end of the limiting sleeve is sleeved on the outside of the guide sleeve, and the lower end of the limiting sleeve is movably connected to the guide sleeve.

[0011] Preferably, the outer side of the transmission belt is provided with a sealing cover that is fixedly connected to the support frame, the driving gear and the driven gear sleeve are respectively movably connected to the upper and lower ends of the sealing cover, and the driven gear sleeve is fixedly connected to the front end of the guide sleeve.

[0012] The advantages of this utility model are: 1. This utility model guides the copper-clad steel wire using guide rollers, allowing it to pass through the first guide sleeve, then the support plate, and finally exit through the second guide sleeve. Throughout this process, the copper-clad steel wire remains straight, preventing scratches. During this process, a pump delivers flux into the first fixed pipe, spraying it onto the copper-clad steel wire. Then, a shaping groove inside the positioning sleeve limits and shapes the flux coating on the surface of the copper-clad steel wire, ensuring uniformity and improving its quality. Finally, a hot air blower delivers hot air to the second fixed pipe, heating the shaped copper-clad steel wire and rapidly forming the flux coating on its surface. This invention allows the copper-clad steel wire to remain straight during flux coating application, minimizing scratches and ensuring a uniform coating. It also allows for heating and drying of the coating, facilitating subsequent processing of the copper-clad steel wire. 2. This utility model uses a drive motor to rotate the active gear, which, in conjunction with the transmission belt inside the sealing cover, causes the driven gear sleeve to rotate the guide sleeve. When the guide sleeve rotates, the position of the limiting sleeve is fixed. At this time, the medium can be continuously transported through the conveying groove and the limiting sleeve. A transmission mechanism is provided so that the guide sleeve can be rotated and adjusted during medium transport, which improves the uniformity of flux spraying and the drying effect of flux coating, and further improves the coating construction effect of copper-clad steel wire flux.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 one Figure 7 As shown, a fluxing device for tin-plated copper-clad steel wire includes a fluxing pool 1, a guide roller 2 movably connected to the front end of the fluxing pool 1, and a pair of support frames 3 and a support plate 4 fixedly connected to the rear end of the fluxing pool 1. A fixed pipe 7 is fixedly connected to the lower end of the support frame 3, and a set of guide sleeves 8 are equidistantly arranged directly below the fixed pipe 7. A transmission mechanism 9 is provided at the front end of the guide sleeves 8. The fixed tube 7 has a conveying groove 10 inside, and a limiting sleeve 11 is provided in the center of the opposite face of the fixed tube 7 and the guide sleeve 8. The guide sleeve 8 has a pair of discharge holes 12 inside. During operation, the fluxing device guides the copper-clad steel wire through the flux pool 1 filled with flux via a wire structure, ensuring the flux covers the outside of the copper-clad steel wire for easy processing. However, the wire structure, aided by rollers, causes the copper-clad steel wire to bend. When passing the positioning sleeve 13, the lower part of the copper-clad steel wire rubs severely against the positioning sleeve 13, resulting in scraping and uneven flux distribution. The copper-clad steel wire is first conveyed by the guide roller 2, passing through the first guide sleeve 8, then through the support plate 4, and finally exiting from the second guide sleeve 8. Throughout this process, the copper-clad steel wire remains straight, preventing scraping.

[0018] Furthermore, the transmission mechanism 9 includes a drive motor 15 fixedly connected to the top surface of the support frame 3. The output end of the drive motor 15 is fixedly connected to a drive gear 16. A driven gear sleeve 17 is provided directly below the drive gear 16, and a transmission belt 18 is sleeved on the outer side of the opposite surfaces of the drive gear 16 and the driven gear sleeve 17. During operation, the guide sleeve 8 can be rotated through the transmission mechanism 9, thereby uniformly feeding and heating the copper-clad steel wire, improving the processing effect of the copper-clad steel wire and facilitating subsequent processing.

[0019] Furthermore, the interior of the flux pool 1 is filled with flux, and a delivery pump 5 and a hot air blower 6 are fixedly connected to one side of the flux pool 1. The input end of the delivery pump 5 is fixedly connected to the flux pool 1, and the output end of the delivery pump 5 is fixedly connected to the front fixed pipe 7 of the two fixed pipes 7. The output end of the hot air blower 6 is fixedly connected to the other fixed pipe 7. During operation, the delivery pump 5 is started to extract flux from the flux pool 1 and send it into the first fixed pipe 7. It then enters the limiting sleeve 11 through the delivery groove 10, and then passes through the limiting sleeve 11 and the discharge hole 12 to spray flux onto the part of the copper-clad steel wire that passes through the fixed pipe 7. The hot air fan 6 is started to deliver hot air to the second fixed pipe 7. The hot air then passes through the delivery groove 10 and the discharge hole 12 to heat the shaped copper-clad steel wire, so that the flux coating on its surface can be formed quickly.

[0020] Furthermore, a set of guide grooves are provided on the surface of the guide roller 2, and a set of positioning sleeves 13 are fixedly connected at equal intervals inside the support plate 4. A shaping groove 14 is provided inside the positioning sleeve 13. The shaping groove 14, the two adjacent guide sleeves 8, and the guide grooves on the surface of the guide roller 2 are located on the same axis. During operation, when the copper-clad steel wire passes through the positioning sleeve 13, the shaping groove 14 inside the positioning sleeve 13 limits and shapes the flux coating on the surface of the copper-clad steel wire, making it uniform and standardized, thus improving the quality of the copper-clad steel wire.

[0021] Furthermore, the upper end of the limiting sleeve 11 is fixedly connected to the fixed tube 7, and the limiting sleeve 11 is connected through the conveying groove 10. The lower end of the limiting sleeve 11 is sleeved on the outside of the guide sleeve 8, and the lower end of the limiting sleeve 11 is movably connected to the guide sleeve 8. During operation, when the guide sleeve 8 rotates, the position of the limiting sleeve 11 is fixed. At this time, the medium can be continuously transported through the conveying groove 10 and the limiting sleeve 11, which improves the uniformity of flux spraying and the drying effect of flux coating.

[0022] Furthermore, a sealing cover fixedly connected to the support frame 3 is provided on the outer side of the transmission belt 18, the driving gear 16 and the driven gear sleeve 17 are respectively movably connected to the upper and lower ends of the sealing cover, and the driven gear sleeve 17 is fixedly connected to the front end of the guide sleeve 8. During operation, the drive motor 15 is started to drive the drive gear 16 to rotate, which, together with the transmission belt 18 inside the sealing cover, causes the driven gear sleeve 17 to drive the guide sleeve 8 to rotate.

[0023] Working principle: The feeding end and the receiving end of the copper-clad steel wire are respectively set at both ends of the welding pool 1. During the processing, the copper-clad steel wire passes through the guide groove of the guide roller 2 from the feeding end, then passes through the first guide sleeve 8 and the support plate 4, and then moves out from the second guide sleeve 8. Finally, it is fixedly connected to the receiving end. During this process, the copper-clad steel wire always remains in a straight state. After that, the copper-clad steel wire is wound and fed.

[0024] The delivery pump 5 is started to extract flux from the flux pool 1 and send it into the first fixed pipe 7. It then enters the limiting sleeve 11 through the delivery groove 10, and passes through the limiting sleeve 11 and the discharge hole 12. The flux is sprayed onto the part of the copper-clad steel wire that passes through the fixed pipe 7. When the copper-clad steel wire passes through the positioning sleeve 13, the shaping groove 14 inside the positioning sleeve 13 limits and shapes the flux coating on the surface of the copper-clad steel wire, making it uniform and standard, and improving the quality of the copper-clad steel wire. Finally, the hot air fan 6 is started to deliver hot air to the second fixed pipe 7. The hot air passes through the delivery groove 10 and the discharge hole 12 to heat the shaped copper-clad steel wire, so that the flux coating on its surface is formed quickly, completing the flux coating construction of the copper-clad steel wire.

[0025] During the flux coating process, the drive motor 15 is started to drive the drive gear 16 to rotate. In conjunction with the transmission belt 18 inside the sealing cover, the driven gear sleeve 17 drives the guide sleeve 8 to rotate. When the guide sleeve 8 rotates, the position of the limiting sleeve 11 is fixed. At this time, the medium can be continuously transported through the conveying groove 10 in conjunction with the limiting sleeve 11, which improves the uniformity of flux spraying and the drying effect of flux coating, and further improves the coating construction effect of copper-clad steel wire flux.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
