[0002] A winding device for an automotive motor stator coil is a device used in the process of processing an automotive motor stator to wind and fix the surface coil structure. The automotive motor stator is a key stationary component in a motor or generator, and it plays a crucial role in the automotive electrical system.

[0003] The patent document with the publication number CN118523572B discloses a stator coil winding device, which includes a stator assembly, a coil ramming mechanism arranged inside the stator assembly, a bearing mechanism installed on the stator assembly and the coil ramming mechanism, and a winding mechanism arranged inside the stator assembly; the bearing mechanism includes a plurality of cross bars and two load pressing pad rings arranged on the plurality of cross bars; the coil ramming mechanism includes a wire bundling frame arranged inside the stator assembly, and the wire bundling frame is located between the two load pressing pad rings. At the moment when the tightly wound coil is completed, the coil ramming mechanism that is pushed horizontally can shape and press the wire group until the wound coil is forcibly rammed to avoid the problem of slack or looseness due to the lack of external force on the coil.

[0004] The above-mentioned stator coil winding device has certain deficiencies in use. As shown in the stator structure Figure 9 , a number of winding structures are annularly distributed on its surface. When the coil winding device is in use, the wire is wound around the surface of the winding structure by rotation. The wire is prone to knotting or tangling during the winding rotation and does not have an auxiliary wire guiding function. At the same time, the height and diameter of different specifications of stator structures are different, and the traditional stator structure cannot be arbitrarily adjusted according to the stator structure size, reducing its scope of application. Summary of the Invention

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

[0006] The problems solved by the present invention are:

[0007] 1. When the coil winding device is in use, the wire is wound around the surface of the winding structure by rotation. The wire is prone to knotting or tangling during the winding rotation and does not have an auxiliary wire guiding function. At the same time, the height and diameter of different specifications of stator structures are different, and the traditional stator structure cannot be arbitrarily adjusted according to the stator structure size, reducing its scope of application.

[0008] The purpose of the present invention can be achieved by the following technical solutions:

[0009] An automobile motor stator coil winding device, comprising a fixed base, a winding device and a turntable. The turntable is movably installed at the middle position of the upper end of the fixed base. The winding device is movably installed at one side of the turntable at the upper end of the fixed base. A plurality of groups of mounting rods for installing stator cores are annularly distributed on the upper end of the turntable. Two docking snap rings are spliced and installed on the surface of the mounting rod. The winding device includes a horizontal push rod, a rotating arm and a guiding frame. The rotating arm is movably installed on the outer surface of one end of the horizontal push rod. The guiding frame is fixedly installed at the middle position of one end of the horizontal push rod. A wire sleeve for winding wire is movably installed at one end of the rotating arm.

[0010] As a further technical solution of the present invention, a wire passing hole is provided on the surface of the wire sleeve, and one end of the wire sleeve and the rotating arm are butt-jointed through a shaft body. An expansion rod is movably sleeved in the middle of the rotating arm. The user passes the wire wound on the wire releasing cylinder through the wire passing hole of the wire sleeve, so that one end of the wire is fixed inside the stator core. The rotating arm is used to drive 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 a corresponding angle under the action of the wire, avoiding the wire 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 body, the wire passing hole in the wire sleeve always remains vertical, enabling the wire to pass vertically through the wire sleeve. Through the movable wire sleeve, the wire can be released during wire winding, so that under the rotation of the rotating arm, the wire is wound inside the stator core.

[0011] As a further technical solution of the present invention, guiding clip blocks are movably installed on the outer surfaces of both ends of the guiding frame, and guiding side plates are fixedly installed on the outer surfaces of both sides of the guiding frame. The outer surface of the guiding clip block is an arc structure, and the side of the guiding side plate is inclined. The guiding frame and one end of the horizontal push rod are butt-jointed and fixed through a docking chuck. When the wire sleeve drives the wire to rotate, the guiding clip block can be used to adjust the wire winding position according to the height of the stator core. Secondly, the guiding side plate can be used to adjust the gap position with the stator core, accurately guiding the wire into the gap of the stator core during wire winding, and completing the winding operation between the wire and the stator core during the rotation of the wire.

[0012] As a further technical solution of the present invention, the guide frame and the guide clamping block, as well as the guide frame and the guide side plate, are all movably docked through telescopic arms. A limit chuck is fixedly installed at one end of the telescopic arm, and a limit chute is arranged on the side of the telescopic arm. The diameters, heights, and side gap positions of stator cores of different models are different. By setting the telescopic arms, the position adjustment of the guide structures at both ends and on both sides of the guide frame can be carried out. By pulling the guide clamping block, the telescopic arms are driven to move by the guide clamping blocks at the upper and lower ends. According to the height of the stator core, the position of the guide clamping block is adjusted so that the guide clamping block is clamped at the upper and lower ends of the stator core. At the same time, the design of the arc-shaped structure on the surface of the guide clamping block can prevent the wire body from breaking during contact. At the same time, according to the surface gap position of the stator core, by pulling the guide side plate and cooperating with the telescopic arm to adjust the positions of the two groups of guide side plates on both sides, the guide side plates are clamped in the gaps on the surface of the stator core, so as to be applicable to 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 setting the rotating sleeve, the rotating arm can rotate at the telescopic end of the transverse push rod, and the setting of the telescopic rod can adjust the use length of the rotating arm, so that the rotating arm can be adjusted arbitrarily 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 gear. The electric motor and one end of the transverse push rod are butt-jointed and fixed through a fixing frame. During the winding process of the stator coil, the winding device needs to be adjusted correspondingly according to the winding position of the coil. By setting the transverse push rod, the position of the winding device can be adjusted as a whole. At the same time, by using the electric motor to drive the steering gear, the steering gear drives the toothed ring, and the rotating arm is driven to rotate through the toothed ring to complete the wire winding operation, and the fixing frame moves along with the transverse push rod.

[0015] As a further technical solution of the present invention, the mounting rod and the turntable are movably connected through a rotating seat. Gears are installed at the lower ends of the rotating seat and the turntable. Two groups of electric motors are installed at the lower part of the turntable. The turntable is driven to rotate by the cooperation of the electric motors and the gears, so as to adjust 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 tooth body at the output end of another group of electric motors. By using the electric motor to drive the mounting rod, the mounting rod rotates, so as to adjust the processing position of the stator core during the winding process of the stator coil.

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

[0017] As a further technical solution of the present invention, the upper outer surface of the docking collar is inclined. A rolling press is provided on one side of the winding device at the upper end of the fixed base. By designing the inclined structure at the upper end of the docking collar, the resistance during the installation between the stator core and the docking collar 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 wire reels are movably installed inside the rotating frame. When the wire in one wire reel is used up, the rotating frame can be rotated to switch the positions between the two rotating frames.

[0019] Advantages of the present invention:

[0020] 1. By setting the winding device, when the automotive motor stator coil winding device is used, its winding structure is optimized. The wire sleeve is used to prevent the wire structure from being entangled, and the stability of coil winding is improved;

[0021] During operation, the user passes the wire wound on the wire reel through the wire passing hole of the wire sleeve, so that one end of the wire is fixed inside the stator core. The wire is driven to rotate by the rotating arm. When the rotating arm rotates, since the wire sleeve is movably installed at one end of the rotating arm, the wire sleeve maintains a corresponding angle under the action of the wire, avoiding the wire 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 body, the wire sleeve is movably installed at one end of the rotating arm, so that the wire passing hole in the wire sleeve can be kept vertical, and the wire can pass through the wire sleeve vertically. Through the movable wire sleeve, it can be released during wire winding. Thus, under the rotation of the rotating arm, the wire is wound inside the stator core. The wire sleeve plays a guiding role during the wire 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 being entangled, and the wire sleeve can rotate correspondingly following the rotation of the wire. During the stator coil winding process, the winding device needs to be adjusted correspondingly according to the coil winding position. By setting the transverse push rod, the position of the winding device can be adjusted as a whole. At the same time, the electric motor is used to drive the steering gear, so that the steering gear drives the toothed ring, and the toothed ring drives the rotating arm to rotate to complete the wire winding operation. The fixed frame moves along with the transverse push rod.

[0022] 2. By setting up a guiding frame, when the device for winding the stator coil of an automotive motor is in use, it has an auxiliary guiding structure, enabling the coil structure to be precisely wound on the stator surface and allowing for arbitrary adjustment according to the stator size.

[0023] During use, the diameters, heights, and positions of the side gaps of stator cores of different models are different. With the telescopic arm, the positions of the guiding structures at both ends and on both sides of the guiding frame can be adjusted. By pulling the guiding clamping block, the guiding clamping blocks at the upper and lower ends drive the telescopic arm to move, and the position of the guiding clamping block is adjusted according to the height of the stator core, so that the guiding clamping block is stuck at the upper and lower ends of the stator core. At the same time, the arc-shaped structure design on the surface of the guiding clamping block can prevent the wire body from breaking when contacting. Also, according to the position of the surface gap of the stator core, by pulling the guiding side plate and cooperating with the telescopic arm to adjust the positions of the two groups of guiding side plates on both sides, the guiding side plates are stuck in the gaps on the surface of the stator core, thus adapting to stator cores of different sizes. During the winding operation, when the wire body rotates, it contacts the guiding clamping block and the guiding side plate of the guiding frame respectively, and the wire body passes through the gap and winds around the surface of the stator core through the guiding clamping block and the guiding side plate. At the same time, the guiding frame can be adjusted correspondingly according to the horizontal push rod.

[0024] 3. By setting up the mounting rod and the docking snap ring, when the device for winding the stator coil of an automotive motor is in use, it has a rotary combined fixing structure, optimizing the use of the winding device, improving the coil winding efficiency, and being flexibly applicable to stator structures of different sizes.

[0025] During operation, the stator core is sleeved on the mounting rod, and the turntable is driven to rotate by the motor in cooperation with the gear, 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 tooth body at the output end of another motor, and the motor is used to drive the mounting rod to rotate, so as to adjust 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 docking snap ring of the corresponding size according to the diameter of the stator core, and fix the docking snap ring on the surface of the mounting rod by using the thread groove. With the inclined structure design at the upper end of the docking snap ring, the resistance during the installation between the stator core and the docking snap ring can be reduced.

[0037] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features, and their effects of the present invention as follows.

[0038] As Figure 1-9As shown in the figure, an apparatus for winding a stator coil of an automotive motor includes a fixed base 1, a wire winder 3, and a turntable 7. The turntable 7 is movably installed at the middle position of the upper end of the fixed base 1. The wire winder 3 is movably installed on one side of the upper end of the fixed base 1 and above the turntable 7. A number of mounting rods 6 for mounting a stator core 14 are annularly distributed on the upper end of the turntable 7. Two docking snap rings 29 are spliced and installed on the surface of the mounting rod 6. The wire winder 3 includes a horizontal 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 horizontal push rod 8. The guide frame 13 is fixedly installed at the middle position of one end of the horizontal push rod 8. A wire guide sleeve 12 for winding wire is movably installed at one end of the rotating arm 11.

[0039] To solve the problem of wire entanglement during wire winding, as Figure 2 shown in the figure, a wire passing hole is provided on the surface of the wire guide sleeve 12, and one end of the wire guide sleeve 12 and the rotating arm 11 are docked through a shaft body. 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 guide sleeve 12, so that one end of the wire is fixed inside the stator core 14. The rotating arm 11 is used to drive the wire to rotate. When the rotating arm 11 rotates, since the wire guide sleeve 12 is movably installed at one end of the rotating arm 11, the wire guide sleeve 12 maintains a corresponding angle under the action of the wire, avoiding the wire being wound around the surface of the wire guide sleeve 12 when the rotating arm 11 rotates. When the rotating arm 11 drives the wire guide sleeve 12 to rotate, the angle of the wire guide sleeve 12 itself does not change due to the rotation of the rotating arm 11. Under the action of the shaft body, the wire passing hole in the wire guide sleeve 12 always remains vertical, enabling the wire to pass vertically through the wire guide sleeve 12. Through the movable wire guide sleeve 12, the wire can be released during wire winding, so that under the rotation of the rotating arm 11, the wire is wound inside the stator core 14.

[0040] As Figure 3 shown in the figure, guide clamping blocks 16 are movably installed on the outer surfaces of both ends of the guide frame 13. 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 clamping block 16 is an arc structure, and the side of the guide side plate 17 is inclined. The guide frame 13 and one end of the horizontal push rod 8 are fixedly docked through a docking chuck 18. When the wire guide sleeve 12 drives the wire to rotate, the setting of the guide clamping block 16 can be used to adjust the wire winding position according to the height of the stator core 14. Secondly, the setting of the guide side plate 17 can adjust the gap position with the stator core 14. During wire winding, the wire is accurately guided into the gap of the stator core 14, and 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 the stator coil, as Figure 3As shown, the guide frame 13 and the guide clamping block 16, as well as the guide frame 13 and the guide side plate 17, are all movably docked through the telescopic arm 19. A limit chuck 20 is fixedly installed at one end of the telescopic arm 19, and a limit chute 21 is provided on the side of the telescopic arm 19. The diameters, heights, and side gap positions of the stator cores 14 of different models are different. By setting the telescopic arm 19, the position adjustment of the guide structures at both ends and on both sides of the guide frame 13 can be carried out. By pulling the guide clamping block 16, the telescopic arm 19 is driven to move by the guide clamping blocks 16 at the upper and lower ends. According to the height of the stator core 14, the position of the guide clamping block 16 is adjusted so that the guide clamping block 16 is stuck at the upper and lower ends of the stator core 14. At the same time, the design of the arc-shaped structure on the surface of the guide clamping block 16 can avoid the phenomenon of wire breakage during contact. At the same time, according to the surface gap position of the stator core 14, by pulling the guide side plate 17 and cooperating with the telescopic arm 19 to adjust the positions of the two groups of guide side plates 17 on both sides, the guide side plates 17 are stuck in the gaps on the surface of the stator core 14, so as to be applicable to stator cores 14 of different sizes.

[0042] As Figure 5 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. By setting the rotating sleeve 22, the rotating arm 11 can rotate at the telescopic end of the transverse push rod 8. And the setting of the telescopic rod 23 can adjust the use length of the rotating arm 11, so that the rotating arm 11 can be arbitrarily adjusted according to the height of the stator core 14.

[0043] As Figure 5 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 butt-jointed and fixed through a fixing frame 10. During the winding process of the stator coil, the winding device 3 needs to be adjusted correspondingly according to the coil winding position. By setting the transverse push rod 8, the position of the winding device 3 can be adjusted as a whole. At the same time, by driving the steering gear 15 with the electric motor 9, the steering gear 15 drives the toothed ring 24, and the rotating arm 11 is driven to rotate through the toothed ring 24 to complete the wire winding operation, and the fixing frame 10 moves along with the transverse push rod 8.

[0044] As Figure 6As shown, the mounting rod 6 and the turntable 7 are movably connected through a rotating seat 26. A gear 27 is installed at the lower ends of the rotating seat 26 and the turntable 7. Two groups 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 cooperation with the gear 27, so as to adjust the position of the mounting rod 6 on the turntable 7. After the mounting rod 6 rotates to the corresponding position, the gear 27 at the lower end of the turntable 7 will mesh with the tooth body at the output end of another group of motors 25, and the motors 25 are used to drive the mounting rod 6 to rotate, so as to adjust the processing position of the stator core 14 during the winding process of the stator coil.

[0045] Thread grooves 28 for cooperating with the docking collar 29 are provided on the surface of the mounting rod 6. The mounting rod 6 and the docking collar 29 are fixedly docked through the thread grooves 28. The user can rotate and install the docking collar 29 of the corresponding size according to the diameter of the stator core 14, and fix the docking collar 29 on the surface of the mounting rod 6 by means of the thread grooves 28.

[0046] The outer surface of the upper end of the docking collar 29 is inclined. A rolling press 2 is arranged on one side of the winding device 3 at the upper end of the fixed base 1. By using the design of the inclined structure at the upper end of the docking collar 29, the resistance during the installation between the stator core 14 and the docking collar 29 can be reduced.

[0047] A rotating frame 4 is movably installed at the top of the fixed base 1, and two groups of wire reels 5 are movably installed inside the rotating frame 4. When the wire in one wire reel 5 is used up, the position between the two rotating frames 4 can be switched by rotating the rotating frame 4.

[0048] During use, by setting the winding device 3, when the automotive motor stator coil winding device is used, its winding structure is optimized. The wire sleeve 12 is used to prevent the wire structure from being entangled, and the stability of its coil winding is improved;

[0049] During operation, the user passes the wire wound on the wire pay-off reel 5 through the wire threading hole of the wire guide sleeve 12, so that one end of the wire is fixed inside the stator core 14. The wire is driven to rotate by the swing arm 11. When the swing arm 11 rotates, since the wire guide sleeve 12 is movably installed at one end of the swing arm 11, the wire guide sleeve 12 maintains a corresponding angle under the action of the wire, avoiding the wire being wound around the surface of the wire guide sleeve 12 when the swing arm 11 rotates. When the swing arm 11 drives the wire guide sleeve 12 to rotate, the angle of the wire guide sleeve 12 itself does not change with the rotation of the swing arm 11. Under the action of the shaft body, the wire guide sleeve 12 is movably installed at one end of the swing arm 11, so that the wire threading hole in the wire guide sleeve 12 can be kept vertical, enabling the wire to pass vertically through the wire guide sleeve 12. Through the movable wire guide sleeve 12, release can be carried out during wire winding. Thus, under the rotation of the swing arm 11, the wire is wound inside the stator core 14. The wire guide sleeve 12 plays a guiding role during wire winding. The rotation of the wire guide 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 wire guide sleeve 12 can prevent the wire from being wound, enabling the wire guide sleeve 12 to make corresponding rotational changes following the rotation of the wire. During the winding of the stator coil, the winding device 3 needs to be adjusted correspondingly according to the winding position of the coil. By providing the transverse push rod 8, the position of the winding device 3 can be adjusted as a whole. At the same time, the electric motor 9 is used to drive the steering gear 15, so that the steering gear 15 drives the gear ring 24, and the swing arm 11 is driven to rotate by the gear ring 24 to complete the wire winding operation. The fixed frame 10 moves along with the transverse push rod 8;

[0050] By providing the guide frame 13, when the automotive motor stator coil winding device is in use, it has an auxiliary guiding structure, enabling the coil structure to be accurately wound on the stator surface, and can be adjusted arbitrarily according to the stator size;

[0051] During use, the diameters, heights, and side gap positions of the stator cores 14 of different models are different. With the provision of the telescopic arm 19, the positions of the guiding structures at both ends and on both sides of the guiding frame 13 can be adjusted. By pulling the guiding clamping block 16, the guiding clamping blocks 16 at the upper and lower ends drive the telescopic arm 19 to move. According to the height of the stator core 14, the position of the guiding clamping block 16 is adjusted so that the guiding clamping block 16 clamps the upper and lower ends of the stator core 14. At the same time, the design of the arc-shaped structure on the surface of the guiding clamping block 16 can prevent the wire body from breaking during contact. Also, according to the surface gap position of the stator core 14, by pulling the guiding side plate 17 and cooperating with the telescopic arm 19 to adjust the positions of the two groups of guiding side plates 17 on both sides, the guiding side plates 17 are clamped in the gaps on the surface of the stator core 14, thereby being applicable to stator cores 14 of different sizes. During the winding operation, the wire body contacts the guiding clamping block 16 and the guiding side plate 17 of the guiding frame 13 during rotation, and the wire body passes through the gap and winds around the surface of the stator core 14 through the guiding clamping block 16 and the guiding side plate 17. At the same time, the guiding frame 13 can be correspondingly adjusted according to the transverse push rod 8;

[0052] By providing the mounting rod 6 and the docking collar 29, when the automotive motor stator coil winding device is in use, it has a rotary combined fixing structure, optimizing the use of the winder 3, improving the coil winding efficiency, and being flexibly applicable to stator structures of different sizes;

[0053] During operation, the stator core 14 is sleeved on the mounting rod 6, and the turntable 7 is driven to rotate by the motor 25 in cooperation with the 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 engage with the tooth body at the output end of another motor 25, and the motor 25 is used to drive the mounting rod 6 to rotate, so as to adjust the processing position of the stator core 14 during the stator coil winding process, thereby completing the uninterrupted winding operation of the stator core 14. The user can rotate and install the docking collar 29 of the corresponding size according to the diameter of the stator core 14, and the docking collar 29 is sleeved in the middle of the core 14 to adapt to stator cores 14 of different sizes. The docking collar 29 is fixed on the surface of the mounting rod 6 by using the thread groove 28. With the design of the inclined structure at the upper end of the docking collar 29, the resistance during the installation between the stator core 14 and the docking collar 29 can be reduced;

[0054] During winding, when the stator core 14 needs to rotate to the winder 3, the motor structure at the lower part of the turntable 7 is turned off, and the core 14 is located on one side of the winder 3.

[0055] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
