Description

Technical Field

[0001] This utility model relates to the field of enameled wire processing technology, specifically to an annealing device for solder enameled wire. Background Technology

[0002] Enamelled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is softened by annealing, then undergoes multiple coatings and baking processes. However, producing products that meet both standard requirements and customer needs is not easy. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enamelled wires differ, but they all possess four major properties: mechanical, chemical, electrical, and thermal. Annealing is an essential process in enamelled wire production. The purpose of annealing is to heat the copper wire, which has hardened due to lattice changes during the stretching process, to a specific temperature, causing the molecular lattice to rearrange and restore the required softness. Simultaneously, it removes residual lubricant and oil from the surface of the copper wire during stretching, making it easier to coat and ensuring the quality of the insulation. Currently, there are three commonly used annealing methods: coil annealing, continuous annealing on a wire drawing machine, and continuous annealing on an enameling machine. Continuous annealing on a wire drawing machine can ensure that the copper wire is fully annealed, so it is often used. However, in the past, when copper wire was continuously annealed, the copper wire was exposed to the air, and the high temperature of the copper wire during annealing made it easy to oxidize, which affected the quality of the enameled wire. In addition, the copper wire had sufficient annealing time to ensure full annealing. Finally, after annealing, it was necessary to clean the oil stains on the surface of the copper wire in a timely manner. These steps could not be completed simultaneously or were not perfect in the past annealing equipment.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN114058795A discloses an annealing treatment device and method for processing enameled wire. The device includes a heating mechanism, a hot air annealing mechanism, a surface cleaning mechanism, a drive mechanism, and a sealing cover, all mounted on a bracket. The heating mechanism is a spiral copper tube, which is powered by an external radio frequency power source to electromagnetically heat the ferrous copper wire. The hot air annealing mechanism is a hot air box with a heating function, which extends the annealing time of the copper wire and ensures thorough annealing.

[0004] While the existing technical solutions described above can fully and evenly anneal the enameled wire, slowly cool it to prevent hydrogenation from contact with air at high temperatures, and promptly clean the surface stains of the enameled wire, the cleaning brush is installed on the motor's drive shaft, and the motor is directly mounted on the cleaning box. This makes it difficult for workers to quickly disassemble the cleaning brush and clean it after a period of use when it is covered with oil and film, thus affecting work efficiency and subsequent cleaning results.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] An annealing device for solder enameled wire includes a treatment box 1. Inside the treatment box 1, from right to left, a heating cylinder 2, a cooling cylinder 3, and a cleaning cylinder 4 are sequentially embedded. A closed groove is formed between one side of the cleaning cylinder 4 and the outer wall of the treatment box 1. A docking brushing mechanism is installed inside the closed groove. The docking brushing mechanism includes a linkage brushing assembly, a sealing plate 14, two sets of docking plates 5, a splicing assembly, a spinning assembly, and a clamping assembly. The two sets of docking plates 5 are installed at both ends of the sealing plate 14. The docking plates 5 and the sealing plate 14 are slidably connected to the closed groove. The linkage brushing assembly is used to clean the outer wall of the enameled wire, and the splicing assembly is used to assemble and overlap the docking plates 5 and the sealing plate 14. On the treatment box 1 and the washing cylinder 4, the spinning assembly is used to cooperate with the splicing assembly to unlock the locking of the docking plate 5, and the clamping assembly is used to cooperate with the spinning assembly to clamp and tighten the position of the docking plate 5. When in use, the device can clean the outer wall of the enameled wire through the linkage brush assembly. The splicing assembly assembles the docking plate 5 and the sealing plate 14 and places them on the treatment box 1 and the washing cylinder 4. The spinning assembly cooperates with the splicing assembly to unlock the locking of the docking plate 5, and the clamping assembly cooperates with the spinning assembly to clamp and tighten the position of the docking plate 5. The structure is simple and easy to operate, which makes it easy for the staff to quickly take out the brush roller 15 for cleaning and maintenance, improves work efficiency, and ensures the subsequent cleaning effect.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the assembly includes a rotating rod 6 slidably connected inside the docking plate 5. A storage groove is provided on one side of the docking plate 5. A positioning block 7 is installed at one end of the rotating rod 6 inside the storage groove. Clamping plates 8 are installed on both sides of the positioning block 7. An assembly groove is provided on the inner wall of the closed groove where it contacts the docking plate 5. Both the clamping plates 8 and the positioning blocks 7 are slidably connected to the assembly groove. The spinning assembly includes an installation groove located inside the processing box 1 on one side of the assembly groove. First springs 9 are installed at both ends of one side of the inner wall of the installation groove. A clamping disc 10 is installed at the other end of the first spring 9. A movable disc 11 is rotatably connected inside the clamping disc 10. A positioning groove is provided on one side of the movable disc 11, and the positioning groove is engaged with the positioning block 7. First, the docking plate 5 and the closed plate 14 are aligned with the closed groove. The first step is to press the pull ring and squeeze the rotary rod 6, causing the clamping plate 8 and the positioning block 7 to slide into the inner side of the splicing groove and the mounting groove, achieving the splicing and fitting effect. The splicing groove is a cross groove. By pressing the pull ring and squeezing the rotary rod 6 downward, the positioning block 7 is inserted into the inner side of the positioning groove, which causes the clamping disc 10 to compress the first spring 9. One end of the clamping plate 8 contacts the locking plate 12, and the two sets of inclined surfaces contact and squeeze each other. At the same time, the squeezing plate 13 presses and causes the third spring to stretch. After the clamping plate 8 continues to move downward and offsets the locking plate 12, the locking plate 12 is returned to its original position by the second spring. Then, it is pulled back a certain distance, and the protruding end of the clamping plate 8 is also inserted into the inner side of the slot on the locking plate 12. The first spring 9 rebounds and causes the clamping disc 10 to press the clamping plate 8 tightly, thereby locking the position of the docking plate 5 and the sealing plate 14.

[0026] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the clamping assembly includes locking grooves on both sides of the inner wall of the mounting groove. A locking plate 12 is slidably connected to the inner side of the locking groove. Multiple sets of second springs are arranged and installed between one side of the locking plate 12 and the inner wall of the locking groove. The opposite ends of the locking plate 12 and the clamping plate 8 are provided with mutually fitting inclined surfaces. A groove is provided at one bottom end of the locking plate 12, and the groove is engaged with the protruding end of the clamping plate 8. An extrusion groove is provided inside the mating plate 5 outside the rotating rod 6. An extrusion plate 13 is slidably connected to the inner side of the extrusion groove. A third spring is installed between both ends of the pressure plate 13 and the inner wall of the extrusion groove. The extrusion plate 13 is rotatably connected to the rotating rod 6. The end of the rotating rod 6 extending to the outside of the docking plate 5 is rotatably connected to a pull ring. Then, when cleaning and maintenance are required, the pull ring can be fastened again to squeeze the rotating rod 6, allowing the clamping plate 10 to move down again. At the same time, the clamping plate 8 is twisted to the longitudinal direction, and the pull ring is pulled back. The clamping plate 8, together with the sealing plate 14 and the docking plate 5, can be pulled out together to clean and maintain the brush roller 15 on the sealing plate 14.

[0027] In this embodiment, as Figure 1 , Figure 3 and Figure 4As shown, the linkage brush assembly includes multiple sets of brush rollers 15 rotatably connected to one side of the closed plate 14 near the inner side of the brushing cylinder 4. Multiple sets of connecting rods are rotatably connected inside the closed plate 14. One end of the connecting rod is fixedly connected to one end of the brush roller 15. A sprocket 16 is installed at the other end of the connecting rod extending to the outer wall of the closed plate 14. The multiple sets of sprockets 16 are connected by a chain. Two sets of drive plates are arranged on one side of the outer wall of the closed plate 14. A linkage motor 17 is installed at one end of the drive plate. The drive end of the linkage motor 17 is fixedly connected to one side of one set of sprockets 16. Furthermore, starting the linkage motor 17 drives one set of sprockets 16 to rotate. In conjunction with the chain, the other two sets of sprockets 16 are driven to rotate. The connecting rod drives each set of brush rollers 15 to rotate together, thus cleaning the enameled wire.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, a heating coil 18 is installed inside the heating cylinder 2, and hot air blowers 19 are installed at both ends of the top of the processing box 1. An air inlet pipe extending to the inside of the cooling cylinder 3 is installed at the output end of the hot air blower 19, and an air inlet head 20 is installed at the other end of the air inlet pipe. Multiple sets of guide wheels 21 are rotatably connected to the inner wall of the processing box 1. Fixed frames are installed at both ends of the processing box 1, and conveyor wheels 22 are rotatably connected inside the fixed frames. A conveyor motor is installed on one side of the fixed frame, and the drive end of the conveyor motor passes through the fixed frame and is fixedly connected to one end of the conveyor wheel 22. Both ends of the processing box 1 have wire inlets. Furthermore, starting the conveyor motor drives the conveyor wheel 22 to rotate and convey the enameled wire into the device. Multiple sets of guide wheels 21 can assist in conveying the enameled wire. Starting the heating coil 18 can heat the enameled wire. After it enters the inside of the cooling cylinder 3, the hot air blower 19 can be started to blow air to ensure that its temperature does not drop rapidly and cools it down. Then, after entering the inside of the washing cylinder 4, the brush roller 15 can be used for brushing and cleaning.

[0029] The implementation principle of the solder enameled wire annealing treatment device in this application embodiment is as follows: The mating plate 5 and the sealing plate 14 are fitted with the sealing groove. Then, the pull ring is held to press the rotary rod 6, causing the clamping plate 8 and the positioning block 7 to slide into the inner side of the splicing groove and the mounting groove, achieving a splicing and fitting effect. The splicing groove is a cross groove. The pull ring is held and the rotary rod 6 is pressed downwards continuously, causing the positioning block 7 to engage with the inner side of the positioning groove, driving the clamping disc 10 to compress the first spring 9. One end of the clamping plate 8 contacts the locking plate 12, and the two sets of inclined surfaces contact and press against each other. The pressing plate 13 simultaneously presses and stretches the third spring. After the clamping plate 8 continues to move downwards and offsets the locking plate 12, the locking plate 12 is returned to its original position by the second spring. Then, it is pulled back a certain distance, and the protruding end of the clamping plate 8 also engages with the inner side of the slot on the locking plate 12. The first spring 9 returns, causing the clamping disc 10 to press the clamping plate 8 against the groove, thereby adjusting the position of the mating plate 5 and the sealing plate 14. When locking and cleaning / maintenance is required, the pull ring can be pressed again to squeeze the rotating rod 6, causing the clamping plate 10 to move down again. At the same time, the clamping plate 8 is twisted to the longitudinal direction, and the pull ring is pulled back to remove the clamping plate 8 together with the sealing plate 14 and the docking plate 5. The brush rollers 15 on the sealing plate 14 are then cleaned and maintained. The linkage motor 17 is started to drive one set of sprockets 16 to rotate, and the chain drives the other two sets of sprockets 16 to rotate. The connecting rod drives each set of brush rollers 15 to rotate together to brush and clean the enameled wire. The conveyor motor is started to drive the conveyor wheel 22 to rotate and convey the enameled wire into the device. Multiple sets of guide wheels 21 can assist in conveying the enameled wire. The heating coil 18 is started to heat the enameled wire. After it enters the cooling cylinder 3, the hot air blower 19 can be started to blow air to ensure that its temperature does not drop rapidly and it cools down. Then, after entering the washing cylinder 4, the brush rollers 15 can be used for brushing and cleaning.

[0030] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
