Description

Technical Field

[0001] The present invention relates to the technical field of enameled wires, and in particular to processing equipment and a processing technology for parallel multi-core composite enameled wires. Background Art

[0002] The trend toward miniaturization and lightweight design in enameled wire applications requires specialized processing methods, particularly for applications such as chip inductors, toroidal inductors, coreless micromotors, and detection signal transmission. These products require multiple enameled wires to be wound in parallel around a single bobbin. Traditionally, this method involves using multiple individual enameled wires automatically wound using a winding machine. However, in actual production, the payout tension varies between different wires, leading to variations in wire length after winding. This directly impacts the consistency of product performance parameters such as resistance and inductance, and can even cause some wires to break.

[0003] Furthermore, some applications require signal transmission via multiple wires, requiring consistent length and alignment, along with excellent mechanical properties. However, using conventional cables for wiring would result in excessive bulk, making it difficult to achieve the required fine wire diameters. Furthermore, enameled wires lack abrasion resistance and environmental resistance.

[0004] In view of this, a parallel multi-core composite enameled wire processing equipment and processing technology are needed to meet these requirements. Summary of the Invention

DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] Example 1

[0045] See Figure 1 The present invention provides a parallel multi-core composite enameled wire, comprising a first core 31, a second core 32, a third core 33, a fourth core 34 and a fifth core 35 arranged in parallel. The outer sides of the first core 31, the second core 32, the third core 33, the fourth core 34 and the fifth core 35 are covered with the outer paint layer 40 of the above-mentioned cores, forming an integrated composite enameled wire structure with a straight line and parallel aggregation arrangement.

[0046] The first core 31 , the second core 32 , the third core 33 , the fourth core 34 and the fifth core 35 have the same diameter.

[0047] Because all wire cores have the same diameter, they have similar resistance, inductance, and transmission characteristics. This means that the performance of different wire cores is consistent, both in terms of signal transmission and circuit connection, making management and maintenance easier. Wire cores of the same diameter can usually be used interchangeably, which increases flexibility and convenience. Wire cores of the same diameter simplify the design and installation of wiring harnesses, reducing the need to manage and match different wire core sizes. This reduces the potential risk of incorrect connections. Whether in terms of current capacity, signal transmission, or other electrical properties, wire cores of the same diameter ensure performance consistency across the entire harness, providing more reliable circuit connections.

[0048] Example 2

[0049] See Figure 2 The present invention provides a parallel multi-core composite enameled wire, comprising a first core 31, a second core 32 and a third core 33 arranged in parallel, the outer sides of the first core 31, the second core 32 and the third core 33 are covered with the outer paint layer 40 of the above cores, forming an integrated composite enameled wire structure with a straight line and parallel aggregation arrangement.

[0050] The diameter of the first core 31 is greater than the diameters of the second core 32 and the third core 33. The diameters of the second core 32 and the third core 33 can be the same or different. Figure 3 The core 30 is a general term for the first core 31, the second core 32 and the third core 33. Based on each core 30, the core 30 itself includes an inner core 301 and an insulating layer 302 wrapped around the outer surface of the inner core 301. The inner core 301 is preferably a copper core.

[0051] By making the diameter of the first core 31 larger, it can be provided with a greater current capacity, thereby adapting to applications requiring higher current, such as those requiring the transmission of large currents or the driving of high-power devices. The diameters of the second core 32 and the third core 33 can be the same or different, which makes the composite enameled wire more versatile in a variety of applications. Cores of different diameters can adapt to different current requirements, thereby expanding the application areas of the wire and providing greater flexibility, making it possible to meet the needs of different applications. Based on specific needs, cores of appropriate diameters can be selected without having to design all cores to the same diameter. By combining cores of different diameters, the performance of the wiring harness can be optimized, while fully utilizing the characteristics of each core, achieving better current transmission and heat dissipation in the composite enameled wire, and improving the overall performance of the wiring harness.

[0052] By using different diameter cores in composite enameled wire, the needs of different applications can be better met, providing greater flexibility and opportunities for performance optimization.

[0053] It can be seen from the solutions of Example 1 and Example 2 that: by coating the outside of each wire core with an insulating varnish layer, the enameled wire ensures sufficient electrical isolation between the wire cores, prevents mutual interference and short circuit of currents, helps maintain electrical separation between the wire cores, and ensures the accuracy of signal transmission; the external varnish layer 40 provides an additional protective layer, which not only increases the wear resistance and resistance to the external environment of the wire core, but also provides mechanical protection and reduces the risk of damage to the wire core.

[0054] The enameled wire design creates a single, parallel, composite enameled wire structure, simplifying wiring and installation. The uniform diameter of the cores further simplifies installation and reduces the possibility of incorrect connections. Furthermore, multi-core cables can be constructed with varying diameters and colors, making it easy to identify and quickly locate the appropriate core for various applications.

[0055] The outer paint layer 40 may be made of a different material than the insulating paint layer 302. Depending on the material selected for the outer paint layer 40, the following functions are achieved:

[0056] When choosing nylon insulating paint material, it increases the slip and wear resistance; when choosing high-temperature resistant insulating paint, it increases the high-temperature resistance and plays a high-temperature protection role; when choosing self-adhesive paint, the multi-core wire can be bonded and fixed between the layers when winding the coil.

[0057] See Figure 4The present invention provides a processing device for manufacturing parallel multi-core composite enameled wire. The device is generally used to produce wire with a diameter of 0.03 to 0.40 mm, with 2 to 7 cores parallelly aggregated in a straight line, with a total width generally less than 5 mm and a thickness less than 0.70 mm. The processing device includes a guide wheel 3 for guiding the multiple strands of wire cores, a wire splitting mechanism for sorting the wires, a gathering mechanism for gathering the wire cores in a straight line in parallel 30, a coating mechanism for applying insulating varnish, an oven 17 for drying the insulating varnish, an air cooler 22 for cooling, and a winding mechanism for winding the multi-core composite enameled wire. The guide wheel 3, the wire splitting mechanism, the gathering mechanism, the coating mechanism, the oven 17, the air cooler 22, and the winding mechanism are arranged in order from front to back.

[0058] The various components of the equipment are arranged in sequence, forming a highly coordinated production process. This layout helps to improve production efficiency and enables each component to work together effectively, thereby accelerating the manufacturing process of composite enameled wire.

[0059] The existence of the branching mechanism ensures that multiple wire cores can be arranged in an orderly manner. This is a key step in manufacturing parallel multi-core composite enameled wires. Through the action of the branching mechanism, each wire core can be correctly positioned to form a parallel arranged wire bundle.

[0060] The equipment includes a coating mechanism and an oven for coating and drying enameled wire, helping to ensure that the applied lacquer layer is uniform and stable to meet product quality standards.

[0061] The presence of the cooling fan 22 can be used to quickly cool the coated enameled wire, ensuring that the varnish layer is solidified and obtains the required physical properties, which helps to improve the quality and stability of the product.

[0062] This arrangement of equipment and process setting helps to achieve a certain degree of automated production, reduces the need for manual intervention, and reduces human errors in production.

[0063] The various mechanisms of the equipment can be set separately or integrated. The integrated setting is preferred. The integrated arrangement of the equipment reduces the complexity of the production line, makes operation more convenient, and makes maintenance and management easier.

[0064] In summary, the layout and functional design of this processing equipment helps to improve the production efficiency, quality and consistency of parallel multi-core composite enameled wire, while reducing the degree of human intervention, making the production process more stable and controllable, which is very beneficial for meeting the demand for high-performance composite enameled wire in different application fields.

[0065] There are multiple guide wheels 3 , which are arranged parallel to each other, and each guide wheel 3 is provided with a V-shaped groove.

[0066] The first mounting block 2 is fixedly mounted on the top of the base plate 1. A supporting leg is provided at the bottom of the base plate 1. A fixing frame is fixedly mounted on the first mounting block 2. Multiple guide wheels 3 are provided on the fixing frame. The guide wheels 3 are fixed to the fixing frame by bolts, and the bolts serve as the rotating shaft for the guide wheels 3 to rotate.

[0067] The parallel arrangement of the plurality of guide wheels 3 helps ensure that the multiple wire cores can be guided in parallel, thereby maintaining a consistent arrangement between the wire cores, and helps to manufacture high quality and consistency of the parallel multi-core composite enameled wire.

[0068] The V-groove design of the guide wheel 3 can better limit the wire cores and ensure that they remain in the correct position, which is very important to avoid the wire cores from being interlaced or confused, especially in high-speed production.

[0069] The V-groove design can reduce the friction between the guide wheel and the wire core, reduce the wear of the wire core, and ensure that the wire core can pass through the guide wheel smoothly during the production process.

[0070] It can be seen that this design helps ensure the stability, consistency and reliability of the production line, and improves the efficiency and quality of producing parallel multi-core composite enameled wire. The parallel arrangement and V-groove design of the guide wheels are particularly helpful in maintaining the correct position and direction of the wire cores, thereby ensuring product consistency.

[0071] The line branching mechanism includes a second mounting block 4, which is fixedly mounted on the top of the base plate 1. The second mounting block 4 is fixedly mounted with a guide plate 5, which is provided with parallel line branching slots 6. The guide plate 5 is preferably a stainless steel sheet.

[0072] Furthermore, in order to increase the smoothness of the wire passing, the wire dividing slot 6 is sprayed with ceramic material to make the wire dividing slot 6 smoother.

[0073] In one embodiment, the diameter of the dividing slots 6 is 1 mm, and the spacing between the dividing slots 6 is 1 mm.

[0074] When in use, the wire core passes through the through hole, and the wires can be threaded in sequence and can be arranged with enameled wires of different colors.

[0075] The wire splitting mechanism can effectively separate the multiple wire cores and arrange them in a specific order through the parallel arrangement of the wire splitting slots 6 on the guide plate 5, ensuring the correct separation and sequential arrangement between the wire cores, which helps to ensure consistency and controllability in the production of parallel multi-core composite enameled wires.

[0076] The diameter and spacing of the branching slots 6 are precisely designed to ensure that the wire cores can accurately pass through the branching slots, and there is enough space when arranging to prevent mutual interference or confusion, which helps to improve the arrangement accuracy of the wire cores.

[0077] The guide plate 5 is made of stainless steel sheet, which has excellent corrosion resistance and mechanical strength, ensuring the durability and reliability of the line dividing mechanism, which is very important for long-term production operation.

[0078] Threading the wires in sequence and using different colored magnet wires provides a simple way to identify each wire core during manufacturing and use, reducing the risk of incorrect connections.

[0079] It can be seen that the design of this wire-dividing mechanism helps to improve the separation, arrangement and identification of wire cores, ensuring the high quality, consistency and reliability of the production of parallel multi-core composite enameled wires. The optimization of the diameter and spacing of the wire-dividing slots and the selection of stainless steel materials help to ensure the long-term performance of the mechanism.

[0080] See Figure 4 and Figure 5 The folding mechanism 10 includes a flat groove bevel wheel 100 and a bevel wheel bracket 101 supporting the flat groove bevel wheel 100. Both surfaces of the flat groove bevel wheel 100 are smooth planes. The angle between the flat groove bevel wheel 100 and the horizontal plane (bottom plate 1) is between 15 degrees and 25 degrees, preferably 20 degrees.

[0081] The flat groove bevel wheel 100 includes a lower wheel plate 102, a convex shaft 107 is provided in the center of the top surface of the lower wheel plate 102, an upper wheel plate 103 is sleeved on the convex shaft 107, a spring 104 is provided on the upper part of the upper wheel plate 103, the spring 104 is sleeved on the convex shaft 107, the end of the convex shaft 107 is provided with a thread and is connected to a nut 105, and the displacement of the upper wheel plate 103 can be limited by adjusting the nut 105 to adapt to wire cores of different wire diameters.

[0082] A bearing 106 is provided at the center of the bottom surface of the lower wheel plate 102, and the upper end of the inclined wheel bracket 101 is set in the bearing 106, so that the lower wheel plate 102 can rotate relative to the inclined wheel bracket 101, and the lower end of the inclined wheel bracket 101 is installed on the base plate 1 or installed on the base plate 1 through a mounting block.

[0083] In one embodiment, the oblique arm of the oblique wheel bracket 101 is parallel to the lower wheel plate 102, and the angle a between the oblique arm of the oblique wheel bracket 101 and the horizontal plane is between 15 degrees and 25 degrees, preferably 20 degrees.

[0084] In one embodiment, the inclined arm of the inclined wheel bracket 101 may not be parallel to the lower wheel plate 102. In this case, the angle with the horizontal plane is required to be between 15 degrees and 25 degrees, preferably 20 degrees.

[0085] The wire core coming from the wire splitting mechanism enters between the lower wheel plate 102 and the upper wheel plate 103, where it is closely arranged. By utilizing the tension of the wire body itself, the wire body moves forward by closely adhering to the flat groove inclined wheel 100.

[0086] The lowermost wire core 30 is slightly larger than the height of the wire dividing slot 6 , and the heights of the other wire cores are all larger than the height of the wire dividing slot 6 .

[0087] The design of the flat groove bevel wheel 100 allows the wire core to fit accurately into the groove of the bevel groove, which helps to ensure that the wire core moves along the correct path during the manufacturing process, thereby maintaining the correct positioning and guidance of the wire core.

[0088] Both sides of the flat groove bevel wheel 100 are smooth planes, which reduces the friction between the wire core and the wire core, helps to reduce the wear of the wire core, and ensures that the wire core can pass through the retracting mechanism smoothly.

[0089] The angle (20 degrees) of the flat groove bevel wheel 100 is precisely controlled to achieve appropriate wire core tension, which helps to ensure that the wire body moves forward steadily in the retracting mechanism 10 and avoids the wire core from becoming loose or too tight during movement.

[0090] It can be seen that the design of this retraction mechanism 10 helps to maintain the correct guidance and positioning of the wire core, reduces the influence of friction and tension, improves production efficiency and protection of the wire core, and ensures the manufacture of high-quality parallel multi-core composite enameled wire.

[0091] See Figure 4 、 Figure 6 and Figure 7 The coating mechanism includes a paint box 7 for storing insulating paint, a processing box 8 is provided on top of the paint box 7, and a support column is provided between the processing box 8 and the paint box 7. A paint inlet pipe 111 and a return pipe 11 are provided between the processing box 8 and the paint box 7. A metering pump 12 for controlling the flow of insulating paint is provided on the paint inlet pipe 111.

[0092] The top end of the return pipe 11 extends into the processing box 8 , and both ends of the paint inlet pipe 111 extend into the paint box 7 and the processing box 8 respectively.

[0093] A metal pressing block 13 is provided in the processing box 8 , an upper felt layer 14 is provided at the bottom of the metal pressing block 13 , a lower felt layer 15 is provided below the bottom of the upper felt layer 14 , and a plurality of wire cores 30 are provided between the lower felt layer 15 and the upper felt layer 14 .

[0094] The flow of insulating varnish can be effectively controlled by the paint inlet pipe 111 and the metering pump 12 provided between the processing box 8 and the paint box 7. This ensures that the amount of insulating varnish applied to the enameled wire can be precisely controlled, thereby maintaining the uniformity and consistency of the coating.

[0095] The provision of the return pipe 11 helps to redirect excess insulating varnish back to the varnish box 7, thus avoiding waste and environmental pollution, thereby helping to improve production efficiency and resource utilization.

[0096] The design of the metal pressing block 13 and the upper and lower felt layers 14 and 15 helps ensure that the enameled wire 30 is subjected to appropriate pressure during the coating process, thereby achieving uniform coating. The felt layer can also evenly distribute the insulating paint to ensure uniform coating.

[0097] Multiple wire cores 30 can be coated in the processing box 8, which improves production efficiency and allows multiple wire cores to be processed simultaneously, which is very beneficial for large-scale production of parallel multi-core composite enameled wires.

[0098] As can be seen, the design of this coating mechanism helps precisely control the flow of insulating varnish, maintaining coating uniformity while minimizing varnish waste. It also allows for the simultaneous processing of multiple wire cores, improving production efficiency and making it suitable for the manufacture of high-quality parallel multi-core composite enameled wire.

[0099] See Figure 4 and Figure 5 An oven 17 is provided on the rear side of the coating mechanism, and a box cover 18 is hingedly installed on the top of the oven 17. Wire slots 19 are provided on the outer walls of both sides of the oven 17. Asbestos boards 20 and thermal insulation cotton 201 are provided in sequence from the inside to the outside of the oven 17, and asbestos boards 20 and thermal insulation cotton 201 are provided in sequence from the inside to the outside of the box cover 18. The asbestos boards 20 and thermal insulation cotton 201 are adapted to the two wire slots 19. A heating wire tube 21 is provided in the oven 17, and the heating wire tube 21 is led out of the box body.

[0100] In one embodiment, the oven 17 can be 800mm-1200mm long, 300mm wide, with a 50mm upper cover and 150mm lower housing height. The front and rear lower housings each have slots 19 approximately 20mm high and 40mm wide for passage of multi-core wires. The slots are equipped with thermocouples for temperature monitoring, and the temperature is controlled by a controller. Heating is preferably set at a temperature between 120°C and 500°C, ensuring that the heating tubes are at a height that prevents friction with the running multi-core enameled wire. The upper and lower housings are insulated with asbestos panels, which are installed at the same angle as the wire distribution slots 6 in the retraction mechanism.

[0101] The oven 17 allows the coated enameled wire to be heated to a temperature ranging from 120°C to approximately 500°C. The oven 17's heating wire tubes 21 and thermocouple temperature detection allow the desired temperature to be precisely controlled and maintained, which is important for ensuring uniform curing of the insulating varnish on the enameled wire, thereby maintaining the quality and consistency of the coating.

[0102] The outer walls of both sides of the oven 17 are provided with wire notches 19, which help the multi-core wire body pass through the oven. The setting of the notches ensures that the wire body can pass through the oven smoothly without being hindered.

[0103] The arrangement of the asbestos board 20 and the thermal insulation wool 201 provides good thermal insulation and heat-insulating effects, helps to maintain a stable temperature in the oven, reduces energy consumption, reduces temperature fluctuations, and improves the efficiency of the oven.

[0104] The design of the oven 17 ensures that the height of the heated tube does not rub against the running multi-core enameled wire, which helps prevent potential damage or safety issues.

[0105] Thermocouples are used to detect the temperature, which is then controlled by a controller. This ensures that the temperature inside the oven is always maintained within the required range, thus ensuring that the applied insulating varnish can be cured correctly.

[0106] It can be seen that the design of the oven 17 helps to ensure a high-quality enameled wire coating process, and provides an efficient, reliable and safe drying environment through precise temperature control, thermal insulation and safety design, which is very beneficial for the production of parallel multi-core composite enameled wire.

[0107] See Figure 4 A cooling fan 22 is provided at the rear of the oven 17 to cool the wire core as it passes through the cooling fan 22 .

[0108] The oven 17 is used to cure the insulating varnish on the enameled wire, while the air cooler 22 is used to quickly cool the enameled wire after coating. This alternating hot and cold treatment can improve the quality and performance of the enameled wire and ensure that they meet the design requirements.

[0109] A winding mechanism is provided at the rear of the oven 17 , and the winding mechanism includes a mounting frame 24 , on which a rotating shaft 25 is mounted, the rotating shaft 25 being connected to a servo motor 26 , the output shaft of the servo motor 26 being fixedly connected to one end of the corresponding rotating shaft 25 , and a winding roller 27 being provided on the circumferential side of the rotating shaft 25 .

[0110] The winding mechanism includes a servo motor 26, which precisely controls the winding speed of the enameled wire. Servomotors are generally more accurate and reliable than traditional variable frequency motors. This helps ensure uniform winding of the enameled wire, avoiding tight or loose wire, thereby improving product consistency.

[0111] Preferably, the servo motor 26 is a variable frequency motor, which has adjustable speed and higher precision, and can adjust the winding speed as needed to improve production flexibility.

[0112] It can be seen that the design of this system helps to ensure high-quality manufacturing of enameled wire during the coating and cooling process, combining an oven, a cooler and a winding mechanism to achieve an efficient and precise production process.

[0113] Processing technology:

[0114] Insulated enameled wire of varying lengths and colors, or even the same color, is guided from guide pulley 3 into the wire-splitting slots 6 of the wire-splitting mechanism. The wires are then separated one by one and fed into the flat-grooved, beveled pulleys 100 of the take-up mechanism 10, ensuring close contact between the wires before entering the coating mechanism. The upper felt layer 14 is temporarily released, and the wires are placed on top of the lower felt layer 15. The height is adjusted to the desired position before entering the drying oven 17. Once normal operation is confirmed, the oven cover 18 is closed, and the wires pass under the cooling fan 22 and enter the take-up roller 27. The multi-core wire is first knotted and reeled onto the take-up roller 27 before entering. The reeling operation is then slowly started. Once all components are confirmed to be normal, the oven 17 begins heating. The desired temperature is set, determined by the material used in the oven 17. The reeling operation is then slow, ensuring that the multi-core enameled wire does not break due to the oven's static heating. When the oven reaches the desired temperature, the dosing pump 12 is activated, with the initial amount of paint set to meet the required coating material supply.

[0115] The working principle of the parallel multi-core composite enameled wire processing equipment provided by the present invention is as follows:

[0116] Step 1: When in use, you can choose to feed the insulated enameled wires of different numbers and colors or the same color through the guide wheel 3 and the wire splitting slot 6. The wires are separated one by one in sequence by the wire splitting mechanism and then enter the flat groove bevel wheel 100 to form a close contact state before entering the paint box 4. The incoming wires are guided by the guide assembly 10 on the paint box 7 and the processing box 8 and enter the processing box 8 through the wire inlet 9;

[0117] The second step: start the metering pump 12, which can extract the insulating paint in the paint box 7 through the paint inlet pipe 111, and then discharge it into the processing box 8 through the paint inlet pipe 111, and then press the wire core 30 with the metal pressing block 13, the upper felt layer 14, and the lower felt layer 15 to paint the wire, and then discharge the wire through the wire inlet 9. The metering pump 12 can set the paint feeding amount per unit time, and the excess paint flows into the paint box 7 from the return pipe 11 for recycling. The paint in the paint box 7 can be the same paint as the thick enameled wire, or self-powder paint or other base paint.

[0118] The third step: the painted wire enters the oven 17 through the wire slot 19, then exits the wire slot 19 on the right side and enters the air cooler 22, and then is discharged through the wire outlet on the air cooler 22 and wound around the winding roller 27. In the oven 17, the painted wire can be dried by energizing the heating wire tube 21 for heating, and the air cooler 22 is started to operate, and the paint wire is discharged into the air cooler 22 through the exhaust pipe to cool the paint wire. The servo motor 26 is started, and the output shaft of the servo motor 26 can drive the rotating shaft 25 and the winding roller 27 to rotate to reel the wire.

[0119] The beneficial effects of implementing the processing equipment and processing technology of the parallel multi-core composite enameled wire provided by the present invention are as follows:

[0120] The equipment is organized from front to back, including guide wheels, wire separation mechanism, take-up mechanism, coating mechanism, oven, air cooler and winding mechanism. This arrangement ensures the continuity of the production process. The wire core can pass through a series of processing steps without additional interruptions or transfers, thereby improving production efficiency.

[0121] The wire-splitting mechanism is used to arrange multiple wire cores in an orderly manner, and the gathering mechanism is used to ensure that the wire cores move along the correct path, which helps to ensure that the wire cores are correctly positioned and guided throughout the entire processing process, reducing the risk of wire core misalignment or twisting.

[0122] The coating mechanism is used to coat the insulating varnish on the wire core, and the oven is used to cure the coated insulating varnish, which helps to ensure that the insulating varnish is evenly coated and completely cured, thereby improving the quality and performance of the enameled wire.

[0123] The cooling air blower is used to quickly cool the coated enameled wire, while the winding mechanism is used to wind the final enameled wire product. These steps help ensure the final quality of the enameled wire while maintaining efficient production speed.

[0124] In summary, by ensuring the continuity of the process, correct line division and guidance, and coordination of steps such as coating, drying, cooling and winding, the consistency and quality of the product are improved, and errors and losses in production are reduced.

[0125] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
