Description

Technical Field

[0001] This invention belongs to the field of stator processing technology, and more specifically, it is a device for winding stator coils of an automotive motor. Background Technology

[0002] An automotive motor stator coil winding device is a device used in the manufacturing process of automotive motor stators to wind and fix the surface coil structure. The automotive motor stator is a key static component in an electric motor or generator, and it plays a vital role in the automotive electrical system.

[0003] Patent document CN118523572B describes a stator coil winding device, including a stator assembly, a coil compaction mechanism disposed inside the stator assembly, a support mechanism mounted on the stator assembly and the coil compaction mechanism, and a winding mechanism disposed within the stator assembly. The support mechanism includes multiple crossbars and two pressure-carrying rings disposed on the crossbars. The coil compaction mechanism includes a wire-binding frame disposed inside the stator assembly, with the wire-binding frame located between the two pressure-carrying rings. The coil, under tension, is immediately compacted and shaped by the horizontally pushed coil compaction mechanism upon completion of winding, until the wound coil is forcibly compacted, thus preventing loosening or unraveling due to the lack of external force.

[0004] The above-mentioned stator coil winding device has certain shortcomings in use, such as the stator structure... Figure 9 As shown, its surface has several sets of winding structures distributed in a ring. When the coil winding device is in use, the wire is wound on the surface of the winding structure by rotation. The wire is prone to knotting or tangling during winding and rotation, and it does not have the function of auxiliary conductor. At the same time, the height and diameter of stator structures of different specifications are different. Traditional stator structures cannot be arbitrarily adjusted according to the size of the stator structure, which reduces its applicability. Summary of the Invention

[0005] The purpose of this invention is to provide a device for winding stator coils of an automotive motor, which can solve existing problems.

[0006] The problem solved by this invention is:

[0007] 1. When using the coil winding device, the wire is wound onto the surface of the winding structure by rotation. The wire is prone to knotting or tangling during the winding rotation. It does not have the function of an auxiliary conductor. At the same time, the height and diameter of stator structures of different specifications are different. Traditional stator structures cannot be arbitrarily adjusted according to the size of the stator structure, which reduces its applicability.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A stator coil winding device for an automotive motor includes a fixed base, a winder, and a turntable. The turntable is movably mounted at the upper middle position of the fixed base. The winder is movably mounted at the upper end of the fixed base, located on one side of the turntable. Several sets of mounting rods for mounting the stator core are arranged in a ring on the upper end of the turntable. Two sets of mating retaining rings are spliced ​​onto the surface of the mounting rods. The winder includes a transverse push rod, a rotating arm, and a guide frame. The rotating arm is movably mounted on the outer surface of one end of the transverse push rod. The guide frame is fixedly mounted at the middle position of one end of the transverse push rod. A wire sleeve for winding is movably mounted on one end of the rotating arm.

[0010] As a further technical solution of the present invention, the surface of the wire sleeve is provided with a wire-passing hole, and one end of the wire sleeve and the rotating arm are connected by a shaft. A telescopic rod is movably sleeved in the middle of the rotating arm. The user passes the wire wound on the wire spool through the wire-passing hole of the wire sleeve, so that one end of the wire is fixed to the inside of the stator core. The rotating arm drives the wire to rotate. When the rotating arm rotates, because the wire sleeve is movably installed at one end of the rotating arm, the wire sleeve maintains the corresponding angle under the action of the wire, avoiding the wire from being wound on the surface of the wire sleeve when the rotating arm rotates. When the rotating arm drives the wire sleeve to rotate, the angle of the wire sleeve itself does not change due to the rotation of the rotating arm. Under the action of the shaft, the wire-passing hole inside the wire sleeve always remains vertical, allowing the wire to pass vertically through the wire sleeve. The movable wire sleeve can be released when the wire is wound, so that the wire is wound to the inside of the stator core under the rotation of the rotating arm.

[0011] As a further technical solution of the present invention, guide clamps are movably installed on the outer surfaces of both ends of the guide frame, and guide side plates are fixedly installed on the outer surfaces of both sides of the guide frame. The outer surface of the guide clamp is an arc-shaped structure, and the side of the guide side plate is inclined. One end of the guide frame and the transverse push rod are connected and fixed by a docking clamp. When the wire sleeve drives the wire to rotate, the guide clamp can be used to adjust the winding position of the wire according to the height of the stator core. Secondly, the guide side plate can be adjusted to match the gap position of the stator core. When the wire is wound, the wire is accurately guided into the gap of the stator core. During the rotation of the wire, the winding operation between the wire and the stator core is completed.

[0012] As a further technical solution of the present invention, the guide frame and the guide clamp block, as well as the guide frame and the guide side plate, are all connected by a telescopic arm. One end of the telescopic arm is fixedly installed with a limit clamp head, and the side of the telescopic arm is provided with a limit groove. Different models of stator cores have different diameters, heights, and side gap positions. By using the telescopic arm, the position of the guide structure at both ends of the guide frame and on both sides can be adjusted. By pulling the guide clamp block, the guide clamp blocks at the upper and lower ends drive the telescopic arm to move. The position of the guide clamp block is adjusted according to the height of the stator core, so that the guide clamp block is locked at the upper and lower ends of the stator core. At the same time, the arc-shaped structure design of the guide clamp block surface can prevent the wire from breaking when in contact. At the same time, according to the surface gap position of the stator core, by pulling the guide side plate, the position of the two sets of guide side plates on both sides is adjusted in conjunction with the telescopic arm, so that the guide side plate is locked in the gap on the surface of the stator core, thus making it suitable for stator cores of different sizes.

[0013] As a further technical solution of the present invention, a rotating sleeve is fixedly installed on the outer surface of the other end of the rotating arm, and a telescopic rod is movably installed in the middle of the rotating arm. By using the rotating sleeve, the rotating arm can rotate at the telescopic end of the transverse push rod, and the telescopic rod can adjust the length of the rotating arm so that the rotating arm can be arbitrarily adjusted according to the height of the stator core.

[0014] As a further technical solution of the present invention, the rotating sleeve is movably installed at one end of the transverse push rod, and a toothed ring is fixedly installed on the outer surface of the rotating sleeve. An electric motor is fixedly installed below the transverse push rod. The electric motor and the toothed ring are driven by a steering tooth. The electric motor and one end of the transverse push rod are connected and fixed by a fixing frame. During the stator coil winding process, the winder needs to be adjusted according to the coil winding position. By using the transverse push rod, the position of the winder can be adjusted as a whole. At the same time, the electric motor drives the steering tooth, which drives the toothed ring. The toothed ring drives the rotating arm to rotate, completing the coil winding operation. The fixing frame moves with the transverse push rod.

[0015] As a further technical solution of the present invention, the mounting rod and the turntable are movably connected by a rotating seat. Gears are installed at the lower ends of the rotating seat and the turntable. Two sets of motors are installed at the lower part of the turntable. The turntable is driven to rotate by the motors and gears, thereby adjusting the position of the mounting rod on the turntable. When the mounting rod rotates to the corresponding position, the gear at the lower end of the turntable will mesh with the output teeth of the other set of motors. The motors drive the mounting rod to rotate, thereby adjusting the processing position of the stator core during the stator coil winding process.

[0016] As a further technical solution of the present invention, the surface of the mounting rod is provided with a threaded groove for use with a docking ring. The mounting rod and the docking ring are fixed together by the threaded groove. The user can rotate and install a docking ring of the corresponding size according to the diameter of the stator core, and use the threaded groove to fix the docking ring on the surface of the mounting rod.

[0017] As a further technical solution of the present invention, the upper outer surface of the docking ring is inclined, and the upper end of the fixed base is provided with a rolling mill on one side of the winding machine. By utilizing the design of the inclined structure at the upper end of the docking ring, the resistance during installation between the stator core and the docking ring can be reduced.

[0018] As a further technical solution of the present invention, a rotating frame is movably installed on the top of the fixed base, and two sets of wire feeding drums are movably installed on the inner side of the rotating frame. When the wire in one set of wire feeding drums is used up, the position between the two sets of rotating frames can be switched by rotating the rotating frame.

[0019] The beneficial effects of this invention are:

[0020] 1. By setting up a winding device, the winding structure of the stator coil winding device of the automobile motor is optimized when it is used. The wire sleeve is used to prevent the wire structure from tangling and improve the winding stability of the coil.

[0021] During operation, the user inserts the wire wound on the spool through the through-hole of the conductor sleeve, fixing one end of the wire to the inside of the stator core. The spool is then driven to rotate. As the spool rotates, the conductor sleeve, movably mounted at one end of the spool, maintains its angle under the influence of the wire, preventing the wire from winding around its surface during rotation. The angle of the conductor sleeve remains unchanged as the spool rotates. The shaft's action keeps the conductor sleeve movably mounted at one end of the spool, ensuring the through-hole remains vertical, allowing the wire to pass vertically through the sleeve. This movable conductor sleeve allows for release of the wire during winding. Thus, under the rotation of the rotating arm, the wire is wound around the inside of the stator core. The wire sleeve plays a guiding role in the winding process. The rotation of the wire sleeve drives the wire to rotate, so that the wire is wound on the surface of the stator core. At the same time, the movable wire sleeve can prevent the wire from getting tangled, allowing the wire sleeve to rotate accordingly with the wire. During the stator coil winding process, the winder needs to be adjusted according to the winding position of the coil. The position of the winder can be adjusted as a whole by using the setting of the transverse push rod. At the same time, the electric motor drives the steering gear, which drives the gear ring, which drives the rotating arm to rotate, completing the wire winding operation. The fixed frame moves with the transverse push rod.

[0022] 2. By setting a guide frame, the stator coil winding device of the automobile motor has an auxiliary guiding structure when in use, so that the coil structure is accurately wound on the stator surface, and can be adjusted arbitrarily according to the stator size;

[0023] In use, different models of stator cores have different diameters, heights, and side gap positions. The telescopic arm allows for adjustment of the guide structure at both ends and sides of the guide frame. By pulling the guide clamps, the upper and lower guide clamps move the telescopic arm. Adjusting the position of the guide clamps according to the stator core height ensures they are engaged at the upper and lower ends. The arc-shaped design of the guide clamp surface prevents breakage of the wire upon contact. Furthermore, by pulling the guide side plates in conjunction with the telescopic arm, the positions of the two sets of guide side plates on both sides are adjusted according to the surface gap position of the stator core, ensuring they are engaged within the gaps on the stator core surface. This allows for the use of stator cores of different sizes. During winding, the wire contacts the guide clamps and guide side plates of the guide frame as it rotates, allowing the wire to pass through the gaps and wind around the surface of the stator core. The guide frame can also be adjusted according to the transverse push rod.

[0024] 3. By setting up mounting rods and docking rings, the automotive motor stator coil winding device has a rotary combination fixing structure when in use, which optimizes the use of the winder, improves the coil winding efficiency, and flexibly applies to stator structures of different sizes.

[0025] During operation, the stator core is placed on the mounting rod. The turntable is driven to rotate by a motor and gears, thereby adjusting the position of the mounting rod on the turntable. When the mounting rod rotates to the corresponding position, the gear at the lower end of the turntable will mesh with the output teeth of another set of motors. The motor drives the mounting rod to rotate, thereby adjusting the processing position of the stator core during the stator coil winding process, thus completing the uninterrupted winding operation of the stator core. The user can rotate and install the corresponding size docking ring according to the diameter of the stator core. The docking ring is fixed to the surface of the mounting rod using the threaded groove. The inclined structure at the upper end of the docking ring can reduce the resistance during installation between the stator core and the docking ring. Attached Figure Description

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0038] like Figure 1-9As shown, an automotive motor stator coil winding device includes a fixed base 1, a winder 3, and a turntable 7. The turntable 7 is movably installed at the upper middle position of the fixed base 1. The winder 3 is movably installed at the upper end of the fixed base 1, located on one side of the turntable 7. Several sets of mounting rods 6 for mounting stator cores 14 are arranged in a ring at the upper end of the turntable 7. Two sets of mating retaining rings 29 are spliced ​​on the surface of the mounting rods 6. The winder 3 includes a transverse push rod 8, a rotating arm 11, and a guide frame 13. The rotating arm 11 is movably installed on the outer surface of one end of the transverse push rod 8. The guide frame 13 is fixedly installed at the middle position of one end of the transverse push rod 8. A wire sleeve 12 for winding is movably installed at one end of the rotating arm 11.

[0039] To solve the problem of tangling during wire winding, such as Figure 2 As shown, the surface of the wire sleeve 12 is provided with a wire-passing hole, and one end of the wire sleeve 12 is connected to the rotating arm 11 via a shaft. A telescopic rod 23 is movably sleeved in the middle of the rotating arm 11. The user passes the wire wound on the wire reel 5 through the wire-passing hole of the wire sleeve 12, so that one end of the wire is fixed to the inside of the stator core 14. The rotating arm 11 drives the wire to rotate. When the rotating arm 11 rotates, because the wire sleeve 12 is movably installed at one end of the rotating arm 11, the wire sleeve 12 maintains a corresponding angle under the action of the wire. To prevent the wire from getting wrapped around the surface of the conductor sleeve 12 when the rotating arm 11 rotates, the angle of the conductor sleeve 12 itself does not change when the rotating arm 11 rotates. Under the action of the shaft, the wire hole inside the conductor sleeve 12 always remains vertical, allowing the wire to pass vertically through the conductor sleeve 12. The movable conductor sleeve 12 can be released when the wire is wrapped, so that the wire is wrapped around the inside of the stator core 14 when the rotating arm 11 rotates.

[0040] like Figure 3 As shown, guide clamps 16 are movably installed on the outer surfaces of both ends of the guide frame 13, and guide side plates 17 are fixedly installed on the outer surfaces of both sides of the guide frame 13. The outer surface of the guide clamps 16 is an arc-shaped structure, and the side of the guide side plates 17 is inclined. The guide frame 13 and one end of the transverse push rod 8 are connected and fixed by the docking clamp 18. When the wire sleeve 12 drives the wire to rotate, the guide clamps 16 can be used to adjust the winding position of the wire according to the height of the stator core 14. Secondly, the guide side plates 17 can be adjusted to the gap position of the stator core 14. When the wire is wound, the wire is accurately guided into the gap of the stator core 14. During the rotation of the wire, the winding operation between the wire and the stator core 14 is completed.

[0041] To improve the winding accuracy of stator coils, such as Figure 3As shown, the guide frame 13 and the guide clamp 16, as well as the guide frame 13 and the guide side plate 17, are all movably connected via telescopic arms 19. A limit clamp 20 is fixedly installed at one end of the telescopic arm 19, and a limit groove 21 is provided on the side of the telescopic arm 19. Different models of stator cores 14 have different diameters, heights, and side gap positions. Using the telescopic arm 19, the position of the guide structures at both ends and on both sides of the guide frame 13 can be adjusted. By pulling the guide clamp 16, the guide clamps 16 at both ends move the telescopic arm 19. The guide clamp 16 is adjusted according to the height of the stator core 14, so that the guide clamp 16 is locked at the upper and lower ends of the stator core 14. At the same time, the arc-shaped structure design of the surface of the guide clamp 16 can prevent the wire from breaking when in contact. Meanwhile, according to the position of the gap on the surface of the stator core 14, the guide side plate 17 is pulled and the position of the two sets of guide side plates 17 on both sides is adjusted in conjunction with the telescopic arm 19, so that the guide side plate 17 is locked in the gap on the surface of the stator core 14, thus accommodating stator cores 14 of different sizes.

[0042] like Figure 5 As shown, a rotating sleeve 22 is fixedly installed on the outer surface of the other end of the rotating arm 11, and a telescopic rod 23 is movably installed in the middle of the rotating arm 11. The rotating sleeve 22 is used to allow the rotating arm 11 to rotate at the telescopic end of the transverse push rod 8. The telescopic rod 23 can be used to adjust the length of the rotating arm 11, allowing the rotating arm 11 to be adjusted arbitrarily according to the height of the stator core 14.

[0043] like Figure 5 As shown, the rotating sleeve 22 is movably installed at one end of the transverse push rod 8, and a toothed ring 24 is fixedly installed on the outer surface of the rotating sleeve 22. An electric motor 9 is fixedly installed below the transverse push rod 8. The electric motor 9 and the toothed ring 24 are driven by a steering gear 15. The electric motor 9 and one end of the transverse push rod 8 are connected and fixed by a fixing bracket 10. During the stator coil winding process, the winder 3 needs to be adjusted according to the coil winding position. By using the transverse push rod 8, the position of the winder 3 can be adjusted as a whole. At the same time, the electric motor 9 drives the steering gear 15, which drives the toothed ring 24. The toothed ring 24 drives the rotating arm 11 to rotate, completing the wire winding operation. The fixing bracket 10 moves with the transverse push rod 8.

[0044] like Figure 6As shown, the mounting rod 6 and the turntable 7 are movably connected by a rotating seat 26. Gears 27 are installed at the lower ends of the rotating seat 26 and the turntable 7. Two sets of motors 25 are installed at the lower part of the turntable 7. The turntable 7 is driven to rotate by the motors 25 in conjunction with the gears 27, thereby adjusting the position of the mounting rod 6 on the turntable 7. When the mounting rod 6 rotates to the corresponding position, the gears 27 at the lower end of the turntable 7 will mesh with the output teeth of the other set of motors 25, and the motors 25 will drive the mounting rod 6 to rotate, thereby adjusting the processing position of the stator core 14 during the stator coil winding process.

[0045] The surface of the mounting rod 6 is provided with a threaded groove 28 for use with the docking ring 29. The mounting rod 6 and the docking ring 29 are fixed together by the threaded groove 28. The user can rotate and install the docking ring 29 of the corresponding size according to the diameter of the stator core 14, and use the threaded groove 28 to fix the docking ring 29 to the surface of the mounting rod 6.

[0046] The upper outer surface of the docking ring 29 is inclined. The upper end of the fixed base 1 is located on one side of the winder 3 and a roller 2 is provided. By utilizing the inclined structure of the upper end of the docking ring 29, the resistance during installation between the stator core 14 and the docking ring 29 can be reduced.

[0047] A rotating frame 4 is movably mounted on the top of the fixed base 1, and two sets of wire feeding drums 5 are movably mounted on the inner side of the rotating frame 4. When the wire in one set of wire feeding drums 5 is used up, the position between the two sets of rotating frames 4 can be switched by rotating the rotating frame 4.

[0048] When in use, by setting the winder 3, the winding structure of the stator coil winding device of the automobile motor is optimized, and the wire sleeve 12 is used to prevent the wire structure from tangling, thereby improving the winding stability of the coil.

[0049] During operation, the user passes the wire wound on the reel 5 through the through hole of the wire sleeve 12, fixing one end of the wire to the inside of the stator core 14. The user then uses the rotating arm 11 to drive the wire to rotate. As the rotating arm 11 rotates, the wire sleeve 12, movably mounted on one end of the rotating arm 11, maintains its angle under the action of the wire, preventing the wire from winding around the surface of the wire sleeve 12 during rotation. While the rotating arm 11 drives the wire sleeve 12 to rotate, the angle of the wire sleeve 12 itself does not change due to the rotation of the rotating arm 11. Under the action of the shaft, the wire sleeve 12, movably mounted on one end of the rotating arm 11, keeps the through hole inside the wire sleeve 12 vertical, allowing the wire to pass vertically through the wire sleeve 12. Through the movable wire sleeve 12, the wire can be wound more smoothly during the winding process. The wire is released, and under the rotation of the rotating arm 11, the wire is wound around the inside of the stator core 14. The wire sleeve 12 plays a guiding role in the winding process. The rotation of the wire sleeve 12 drives the wire to rotate, so that the wire is wound on the surface of the stator core 14. At the same time, the movable structure of the wire sleeve 12 can prevent the wire from getting tangled, and the wire sleeve 12 can rotate and change accordingly with the rotation of the wire. During the stator coil winding process, the winder 3 needs to be adjusted according to the coil winding position. The position of the winder 3 can be adjusted as a whole by using the setting of the transverse push rod 8. At the same time, the electric motor 9 drives the steering gear 15, so that the steering gear 15 drives the gear ring 24, and the gear ring 24 drives the rotating arm 11 to rotate, completing the wire winding operation. The fixed frame 10 moves with the transverse push rod 8.

[0050] By setting the guide frame 13, when the automotive motor stator coil winding device is used, it has an auxiliary guiding structure, which allows the coil structure to be accurately wound on the stator surface, and can be adjusted arbitrarily according to the stator size.

[0051] In use, different models of stator cores 14 have different diameters, heights, and side gap positions. The telescopic arm 19 allows for adjustment of the guide structures at both ends and sides of the guide frame 13. By pulling the guide clamps 16, the upper and lower guide clamps 16 move the telescopic arm 19. Adjusting the position of the guide clamps 16 according to the height of the stator core 14 ensures that the guide clamps 16 are engaged at the upper and lower ends of the stator core 14. Furthermore, the arc-shaped design of the guide clamps 16 prevents wire breakage upon contact. Meanwhile, based on the position of the surface gap of the stator core 14, the guide side plate 17 is pulled and the position of the two sets of guide side plates 17 on both sides is adjusted in conjunction with the telescopic arm 19, so that the guide side plate 17 is stuck in the gap on the surface of the stator core 14, thus accommodating stator cores 14 of different sizes. During the winding operation, when the wire rotates, it contacts the guide clamp 16 and the guide side plate 17 of the guide frame 13 respectively. The guide clamp 16 and the guide side plate 17 allow the wire to pass through the gap and wrap around the surface of the stator core 14. At the same time, the guide frame 13 can be adjusted accordingly according to the transverse push rod 8.

[0052] By setting the mounting rod 6 and the docking ring 29, the automotive motor stator coil winding device has a rotary combination fixing structure when in use, which optimizes the use of the winder 3, improves the coil winding efficiency, and flexibly applies to stator structures of different sizes.

[0053] During operation, the stator core 14 is fitted onto the mounting rod 6. The turntable 7 is driven to rotate by the motor 25 and gear 27, thereby adjusting the position of the mounting rod 6 on the turntable 7. When the mounting rod 6 rotates to the corresponding position, the gear 27 at the lower end of the turntable 7 will mesh with the output teeth of another set of motors 25. The motor 25 drives the mounting rod 6 to rotate, thereby adjusting the processing position of the stator core 14 during the stator coil winding process, thus completing the uninterrupted winding operation of the stator core 14. The user can rotate and install the corresponding size docking ring 29 according to the diameter of the stator core 14. The docking ring 29 is fitted into the middle of the core 14 to accommodate stator cores 14 of different sizes. The docking ring 29 is fixed to the surface of the mounting rod 6 by the threaded groove 28. The design of the inclined structure at the upper end of the docking ring 29 can reduce the resistance during installation between the stator core 14 and the docking ring 29.

[0054] When winding, when the stator core 14 needs to rotate to the winder 3, the motor structure under the turntable 7 is turned off, so that the core 14 is located on one side of the winder 3.
