Description

Technical Field

[0001] This utility model relates to the field of motor processing technology, specifically to a motor coil winding device. Background Technology

[0002] The motor coil is the core component of a motor, enabling the "electromagnetic-mechanical" energy conversion. It is made by combining various specifications of wire in specific quantities into a single strand, which is then wound into a coil with specific shapes and parameters. Different specifications of wire exhibit significant differences in conductivity, mechanical strength, and heat resistance. By rationally combining wires of various specifications, the advantages of each wire can be comprehensively utilized to optimize coil performance. In existing technologies, when multiple independent wires are brought together, the wires are drawn from their respective pay-off reels and directly converged onto a fixed wire-gathering ring or guide wheel, merging into a single strand before being guided to a winding machine for winding.

[0003] Existing winding devices have significant drawbacks in practical applications. First, they lack an independent wire separating device. After the wire is drawn from the pay-off reel, it twists and swings randomly. When multiple wires swing together, they become tangled or even knotted.

[0004] Secondly, the wire gathering section typically uses only a single wire gathering ring or guide wheel, which is ineffective for gathering multiple specifications and quantities of wire. Individual wires may detach, and the lack of a restraining structure makes it difficult to achieve tight and uniform gathering of the strands. This results in loose and unevenly arranged strands with gaps, directly affecting the quality of subsequent winding and causing defects in both appearance and performance of the wound coil. Furthermore, the lack of an independent and reliable tension control mechanism leads to inconsistent wire tension, resulting in coils with varying tightness, severely impacting the mechanical strength and consistency of the product. Utility Model Content

[0005] The present invention aims to provide a motor coil winding device to avoid tangling and knotting of wires of various specifications during winding, thereby improving the quality of the motor coil.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A motor coil winding device includes an independent wire feeding mechanism and a winding mechanism. The wire feeding mechanism includes a wire feeding box, a wire separating device, and a wire gathering device arranged sequentially from bottom to top. The wire feeding box has several wire feeding slots for placing coiled wire. The wire separating device is fixed above the wire feeding box by pillars at the four corners of the wire feeding box. The wire separating device includes several wire separating units that match the positions of the wire feeding slots. The wire gathering device is fixed above the wire separating device by pillars and is used to gather all the wires into one strand. The winding mechanism includes a winding machine and a winding mold fixed on the winding machine. The winding mold is used to wind the stranded wire into shape.

[0007] The principles and advantages of this scheme are: 1. The process of converging multiple wires into a single wire and winding it is achieved through independent wire feeding and winding mechanisms. This allows for flexible layout adjustments based on site or process requirements, adapting to different production line configurations. The wire feeding mechanism sequentially completes the wire feeding-splitting-gathering work through the wire feeding box, wire separating device, and wire gathering device. The winding mechanism completes the final winding into a coil. Each device has a clear function and a simple structure, facilitating equipment manufacturing, installation, maintenance, and subsequent process optimization.

[0008] 2. The number and position of the line splitting units are matched with the number and position of the line feeding slots. The line splitting units separate the lines of several coils in space, avoiding tangling and knotting between the lines. The fixed position makes the direction of each line fixed, and the converged lines are smoother and more uniform.

[0009] Preferably, as an improvement, the top opening of the cable tray is provided with a cover plate that does not completely cover it, and the top of the cable tray is provided with support blocks at two non-adjacent diagonals that support the cover plate, and the cover plate is provided with a cable outlet hole.

[0010] Technical benefits: This solution employs the above-mentioned setup, where the cover plate does not completely cover the wire, allowing operators to visually observe the specifications and remaining quantity of the coiled wire inside the wire feeding trough. This facilitates timely replenishment and replacement, ensuring continuous production. The two ends of the cover plate are secured at two non-adjacent diagonal points on the top of the wire feeding trough, with both diagonal sidewalls providing support for the cover plate. This ensures that the cover plate will not easily shake or shift during device operation, thereby guaranteeing the stability of the wire feeding process. The wire outlet hole of the cover plate serves as a preliminary guide and limiter, preventing the wire from swinging disorderly at the outlet.

[0011] Preferably, as an improvement, the cover plate is further provided with a cover plate slot, one end of which is connected to the cover plate outlet hole, and the other end passes through the edge of the cover plate, and the inner wall of the cover plate slot is provided with a rubber strip.

[0012] Technical benefits: This solution, with the above-mentioned setup, eliminates the need for threading through the bottom of the small cover plate outlet hole. The wire can be easily moved into the outlet hole from the cover plate slot, reducing operational difficulty and time, and improving production efficiency. The rubber strip on the inner wall of the cover plate slot has a certain degree of elasticity and friction, which can effectively prevent the wire from accidentally coming out of the cover plate slot when tension changes or vibration occurs, ensuring the stability of the wire exit.

[0013] Preferably, as an improvement, the cable splitting device includes two support rods and a plurality of cable splitting plates. The support rods are located above the two non-adjacent sides of the cable distribution box, and their two ends are fixedly connected to the support columns respectively. The plurality of cable splitting plates are arranged between the two support rods, and their two ends are fixedly connected to the support rods on both sides respectively. The cable splitting unit is arranged on the cable splitting plate, and the cable splitting unit includes cable splitting plate outlet holes and cable splitting plate slots arranged on the cable splitting plate.

[0014] Technical effect: The above-mentioned setup provides each wire with an independent, fixed-position wire outlet hole, which completely isolates each wire in physical space and fundamentally avoids the problem of multiple wires getting tangled and knotted during travel.

[0015] Preferably, as an improvement, one end of the splitter plate slot is connected to the cable outlet hole of the splitter plate, and the other end passes through the edge of the splitter plate, and a rubber strip is provided on the inner wall of the splitter plate slot.

[0016] Technical benefits: The above-mentioned setup facilitates wire threading, allowing the wire to be easily moved from the wire divider slot into the wire outlet hole. The rubber strip on the inner wall of the wire divider slot has a certain degree of elasticity and friction, which effectively prevents the wire from accidentally coming out of the wire divider slot when tension changes or vibration occurs, ensuring the stability of the wire exit.

[0017] Preferably, as an improvement, the cable bus device includes a support plate, a column, and a first cable ring, a second cable ring, and two guide wheels arranged sequentially from bottom to top on the column. The two ends of the support plate are fixedly connected to two non-adjacent columns, the column is mounted on a support rod and threadedly connected to the support rod, the guide wheels are rotatably connected to the column through a rotating shaft, the outer wheel surface of the guide wheels is provided with a cable groove, and the outer wheel surfaces of the two guide wheels are fitted together.

[0018] Technical benefits: This solution adopts the above-mentioned setup, with the column and support rod threaded together. The rotating support column can drive the entire wire feeding device to rotate, thereby adjusting the wire output direction. This allows the equipment to flexibly adapt to different workshop layouts and winding machine positions. The closed wire hole formed by the two guide wheels can guide the wire to the winding mechanism, prevent wire dispersion, and minimize wear on the wire through rolling friction, ensuring the surface quality of the wire.

[0019] Preferably, as an improvement, the inner surfaces of both the first and second bus rings are variable diameter structures with a smaller top and a larger bottom, and the inner diameter of the top of the first bus ring is equal to the inner diameter of the bottom of the second bus ring.

[0020] Technical effect: The above settings in this solution allow for a smooth and gradual two-stage gathering of the wires, which is more effective than a single, rapid gathering in combining multiple wires into a single strand more evenly and smoothly.

[0021] Preferably, as an improvement, the winding machine is provided with a rotating rod, the winding machine drives the rotating rod to rotate, a limiting block is provided on the rotating rod near one end of the winding machine, the winding mold is sleeved on the rotating rod and one side is in contact with the limiting block, and the winding mold is fixed on the rotating rod by a fixing nut.

[0022] Technical benefits: With the above-mentioned setup, the winding mold is fixed to the rotating rod by the limiting block and the fixing nut, which ensures the initial positioning of the winding mold on the rotating rod and prevents axial movement during rotation, thus ensuring the accuracy of the winding dimensions. The winding mold is fixed by the fixing nut, making installation and disassembly convenient.

[0023] Preferably, as an improvement, the winding die includes multiple partitions and multiple inner supports. The inner supports are located between two partitions. Each inner support includes a first inner support block and a second inner support block. The first inner support block and the second inner support block are respectively disposed on opposite surfaces of two adjacent partitions and located on different sides. The first inner support block has a first inclined surface on the side closer to the second inner support block, and the second inner support block has a second inclined surface on the side closer to the first inner support block that cooperates with and connects to the first inclined surface.

[0024] Technical effect: The above-mentioned setting makes it easy to release the support on the inside of the coil by tapping or squeezing the inner support block relative to the inclined surface after the winding is completed. This allows the partition to be easily removed from the formed coil, solving the problem of difficult demolding after the coil is wound and protecting the shape of the coil from damage.

[0025] Preferably, as an improvement, the winding mechanism further includes a tensioning device, which includes a base, two support plates, a tensioning rod, and a tensioning wheel. The two support plates are fixedly mounted on the base, the tensioning rod is disposed between the two support plates and its two ends are fixedly connected to the two support plates respectively, and the tensioning wheel is sleeved on the tensioning rod. The outer wheel surface of the tensioning wheel is provided with a wire groove.

[0026] Technical effect: The above settings in this solution provide constant tension to the wire with the tensioning wheel, ensuring uniform tension when the wire is wound onto the die, resulting in a tight coil structure, regular shape, and no looseness between turns. Attached Figure Description

Detailed Implementation

[0036] The following detailed description illustrates the specific implementation method: Example The basics are as follows: Figure 1-8 As shown: The motor coil winding device includes independent wire feeding and winding mechanisms. The wire feeding mechanism gathers various wires of different specifications into a single strand according to a preset combination, and then the winding mechanism winds the strand into a coil. Figure 1 As shown, the wire feeding mechanism includes a wire feeding box 1, a wire separating device 3, and a wire gathering device 4 arranged sequentially from bottom to top. The wire feeding box 1 contains several wire feeding slots 11 for placing coiled wire. The wire feeding slots 11 are evenly arranged horizontally and vertically within the wire feeding box 1. The wire separating device 3 is fixed to the top of the wire feeding box 1 by support pillars 2 at its four corners. The wire separating device 3 includes several wire separating units that match the positions of the wire feeding slots 11. The wire separating device 3 separates the wires leading out from the several wire feeding slots 11, preventing multiple wires from tangling and knotting. Figure 5 As shown, the wire gathering device 4 is fixed above the wire splitting device 3 by the support column 2, and is used to gather all the wires into one strand. The winding mechanism includes a winding machine 5 and a winding mold 6 fixed on the winding machine 5. The winding mold 6 is used to wind the stranded wires into shape.

[0037] like Figure 1 As shown, the top opening of the wire feeding trough 11 is provided with a partially covered cover plate 13. The specifications and quantity of the coiled wire inside the wire feeding trough 11 can be seen through the uncovered area, which is convenient for checking the specifications and replacing the coiled wire at any time. Support blocks 12 supporting the cover plate 13 are provided at two non-adjacent diagonals at the top of the wire feeding trough 11. The cover plate 13 is provided with a cover plate wire outlet hole 131. The wire of the coiled wire is led out from the cover plate wire outlet hole 131, which can be used to tighten and control the output speed. The cover plate 13 is also provided with a cover plate slot 132. One end of the cover plate slot 132 is connected to the cover plate wire outlet hole 131, and the other end passes through the edge of the cover plate 13. The wire can be moved from the cover plate slot 132 into the cover plate wire outlet hole 131 without having to align the wire from the bottom of the cover plate wire outlet hole 131 upwards. The inner wall of the cover plate slot 132 is provided with a rubber strip to prevent the wire from leaving the cover plate slot 132 and the cover plate wire outlet hole 131 during the output process.

[0038] like Figure 2 As shown, the cable distribution device 3 includes two support rods 31 and several cable distribution plates 32. The support rods 31 are located above the two non-adjacent sides of the cable feeding box 1, and their two ends are fixedly connected to the support column 2. The several cable distribution plates 32 are arranged between the two support rods 31, and their two ends are fixedly connected to the support rods 31 on both sides. The cable distribution units are arranged on the cable distribution plates 32. The number and position of the cable distribution units match the number and position of the cable feeding slots 11. The cable distribution unit includes a cable distribution plate outlet hole 321 and a cable distribution plate slot 322 arranged on the cable distribution plate 32. The cables from the several cable distribution plates exit the slots. Hole 321 separates several coils of wire, preventing them from tangling and knotting. The fixed positions of the wire outlet holes 321 on the wire divider also fix the direction of each wire, resulting in a smoother and more uniform converging wire. One end of the wire divider slot 322 is connected to the wire outlet hole 321 on the wire divider, and the other end passes through the edge of the wire divider 32. Wires can be moved from the wire divider slot 322 into the wire outlet hole 321. The inner wall of the wire divider slot 322 is provided with a rubber strip to prevent the wire from detaching from the cover plate outlet hole 131 during the wire exit process.

[0039] like Figure 4As shown, the cable concentrator 4 includes a support plate 41, a column 42, and a first cable concentrator ring 43, a second cable concentrator ring 44, and two guide wheels 45 arranged sequentially from bottom to top on the column 42. The two ends of the support plate 41 are fixedly connected to two non-adjacent support columns 2, respectively. The column 42 is mounted on the support rod 31 and is threadedly connected to the support rod 31. By rotating the support rod 31, the orientation of each component on the column 42 can be adjusted, thereby adjusting the outgoing direction of the concentrating cable. The adjustment can be made according to the layout of the site. The guide wheels 45 are rotatably connected to the column 42 through a rotating shaft. The outer wheel surface of the guide wheels 45 is provided with a cable groove, and the outer wheel surfaces of the two guide wheels 45 are fitted together, so that the cable grooves of the two guide wheels 45 form a closed cable hole, which can guide the cable to the winding mechanism and prevent the cable from scattering. Both the inner surfaces of the first cable ring 43 and the second cable ring 44 have a variable diameter structure with a smaller top and a larger bottom, which helps to gather and converge the cables. The inner diameter of the top of the first cable ring 43 is equal to the inner diameter of the bottom of the second cable ring 44. Through the effect of two gatherings, multiple cables of various specifications can be gathered into one cable.

[0040] like Figure 6 As shown, the winding machine 5 is equipped with a rotating rod 51. The winding machine 5 drives the rotating rod 51 to rotate. A limiting block 52 is provided on the rotating rod 51 near one end of the winding machine 5. The winding mold 6 is sleeved on the rotating rod 51, and one side is in contact with the limiting block 52. The winding mold 6 is fixed on the rotating rod 51 by a fixing nut 53. The rotation of the rotating rod 51 drives the winding mold 6 to rotate. With manual assistance, the stranded wire is wound on the winding mold 6 to form a coil.

[0041] like Figure 8 As shown, the winding mold 6 includes multiple partitions 61 and multiple inner support members 62. The inner support members 62 are located between two partitions 61. The inner support members 62 include a first inner support block 621 and a second inner support block 622. The first inner support block 621 and the second inner support block 622 are respectively disposed on the opposite surfaces of two adjacent partitions 61 and are located on different sides. The first inner support block 621 has a first inclined surface on the side near the second inner support block 622, and the second inner support block 622 has a second inclined surface on the side near the first inner support block 621 that is connected to the first inclined surface.

[0042] like Figure 5As shown, the winding mechanism also includes a tensioning device 7. Before the wire enters the winding mold 6 for winding, the tensioning device 7 tensions the wire to ensure consistent tension throughout the wound coil. The tensioning device 7 includes a base 71, two support plates 72, a tensioning rod 73, and a tensioning wheel 74. The two support plates 72 are fixedly mounted on the base 71. The tensioning rod 73 is positioned between the two support plates 72, with both ends fixedly connected to the two support plates 72 respectively. The tensioning wheel 74 is sleeved on the tensioning rod 73 and can slide along and rotate relative to the tensioning rod 73. A groove is provided on the outer surface of the tensioning wheel 74. The stranded wire wraps once around the groove of the tensioning wheel 74 before entering the winding mold 6 for winding. The tensioning wheel 74 rotates as the wire passes through, thus not affecting the passage of the wire while providing tension.

[0043] In actual use, different specifications and quantities of coiled wire are placed in the wire release slot 11 according to requirements. The cover plate 13 is then closed, and the wire ends are pulled out one by one. First, the wire ends enter the wire outlet hole 131 of the cover plate through the slot 132, then enter the wire outlet hole through the slot of the wire outlet plate, and finally pass through the first wire conduit ring 43 and the second wire conduit ring 44 in sequence, and then pass out between the two guide wheels. All coiled wires are operated in the same way. After all the wires pass through the guide wheels, they are gathered into a single strand. The stranded wire is wound once on the tensioning wheel 74, and then the wire is wound on the rotating winding mold 6 with manual assistance. After the winding is completed, the wire is cut, the fixing nut 53 on the rotating rod 51 is unscrewed, and the winding mold 6 and the wound coil are removed together. The winding mold 6 and the coil are then separated.
