Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] A stator coil winding machine, such as Figures 1-4 As shown, the device includes a base 1, which serves as the supporting foundation for the entire device. It is made of cast iron or aluminum alloy to ensure overall rigidity. A side seat 2 is fixed to one side of the base 1. A horizontal turntable 8 is rotatably mounted on the upper end of the base 1 via a bearing. The turntable 8 is driven by a servo motor (not shown in the figure, model Panasonic Minas A6) installed inside the base 1, which can achieve precise indexing rotation. A circular clamp 10 is fixed to the upper end of the base 1. A circular coil frame 9 is coaxially clamped on the turntable 8. Both the turntable 8 and the coil frame 9 are rotatably mounted outside the clamp 10. The coil frame 9 is sleeved outside the clamp 10. The clamp 10, the turntable 8, and the coil frame 9 are coaxial. When the turntable 8 rotates, it drives the upper coil frame 9 to rotate.

[0024] A rectangular slot 11 is provided in the middle of the card holder 10, with both ends of the slot 11 passing through both ends of the card holder 10. An inverted U-shaped bracket 12 is fixedly connected to the upper end of the card holder 10 above the slot 11. A winding seat 13 is vertically slidably installed inside the bracket 12. The winding seat 13 is driven to rise and fall by an electric push rod (not shown in the figure, the power cord of the electric push rod will not affect the rotation of the changing plate 8) installed in the machine base 1. One end of the winding seat 13 is located inside the bracket 12, and the other end is located outside the bracket 12. The cross-sectional shape of the winding seat 13 matches the inner cavity shape of the coil to be wound. A de-rotating device is installed at one end of the winding seat 13. The wire assembly facilitates pushing the coil on the winding seat 13 away from the winding seat 13. A movable seat 4 is slidably installed on the upper end of the side seat 2. A winding rod 7 is rotatably installed on one side of the movable seat 4. The winding rod 7 has a wire-passing hole for the electromagnetic wire to pass through. The movable seat 4 drives the winding rod 7 to move closer to or away from the winding seat 13. Hook assemblies are installed on both sides of the machine base 1. The hook assemblies cooperate with the winding rod 7. When the winding rod 7 is close to the winding seat 13, the hook assemblies retract and hook the electromagnetic wire at the end of the winding rod 7, hooking the electromagnetic wire to one side of the bracket 12, so that the electromagnetic wire can be wound on the winding seat 13.

[0025] The wire-removing assembly includes a wire-removing frame 14. An electric push rod (Thomson Linearact series) is fixedly connected inside the end of the wire-removing seat away from the movable seat 4. The wire-removing frame 14 is U-shaped. The two ends of the wire-removing frame 14 slide on both sides of the winding seat 13 to push the coil wound on the winding seat 13. The output end of the electric push rod is fixedly connected to the middle of the wire-removing frame 14. When the output end of the electric push rod retracts, it can drive the wire-removing frame 14 to slide along the winding seat 13, thereby removing the coil wound on the winding seat 13 from the winding seat 13.

[0026] A movable seat 4 is slidably mounted on the upper end of the side seat 2. A lead screw 3 is also rotatably mounted on the upper end of the side seat 2 via a bearing. The axis of the lead screw 3 is in the same direction as the extension direction of the winding rod 7. The movable seat 4 and the lead screw sleeve of the lead screw 3 are fixedly connected by a connecting plate (the lead screw 3 is driven by a servo motor, Delta ECMA series, not shown in the figure), which can control the forward and backward movement of the movable seat 4. A cavity 5 is opened inside the movable seat 4. A circular plate 6 is rotatably mounted on one end of the cavity 5 near the bracket 12. One end of the hollow winding rod 7 is fixedly connected to the edge of the circular plate 6 at an eccentric position. A wire-passing hole is opened inside the winding rod 7 along its axial direction. The wire-passing hole passes through the entire winding rod 7 and continues through the circular plate 6. The electromagnetic wire enters the wire-passing hole from the cavity 5 and exits from the winding rod 7. The winding rod 7 is driven to rotate by a motor (Leysun Technology 57 series, shown in the figure but not marked) installed in the cavity 5. The winding rod 7 surrounds the winding seat 13, winding the electromagnetic wire onto the winding seat 13.

[0027] When the winding rod 7 approaches the winding seat 13, the extension end of the cylinder 16 (SMC MGPM series) retracts, the bent rod 18 hooks the electromagnetic wire, and pulls the electromagnetic wire to one side of the winding seat 13. The bent rod 18 is located on one side of the bracket 12. The winding rod 7 rotates to wind the electromagnetic wire onto the winding seat 13. After the winding is completed, the winding rod 7 disengages from the winding seat 13, the wire pulling assembly extends and disengages from the electromagnetic wire, and the winding seat 13 descends into the slot 11.

[0028] A cylinder 19 (SMC MXQ series) is fixedly connected to the upper end of the base 1. The output end of the cylinder 19 drives the electric slide table 20 (TOYO-GTH8) to rise and fall to a certain extent. The moving end of the electric slide table 20 is fixedly connected to a slide block 21. A fixed rod 22 is fixedly connected to the slide block 21. A pressure rod 23 for pressing the coil is fixedly connected to the bottom of the fixed rod 22. The cylinder 19 and the electric slide table 20 drive the fixed rod 22 to rise or move, pressing the upper end of the wound coil and initially shaping the stator coil.

[0029] The working principle of the stator coil winding machine provided by this utility model is as follows:

[0030] In the initial state, the winding seat 13 is in the upper position, the moving seat 4 is in the retracted position away from the bracket 12, the hook assembly is in the extended state, the unwinding assembly is in the retracted state, the winding rod 7 is located at the leftmost or rightmost position of the circular plate 6, the coil frame 9 is installed on the turntable 8, the electromagnetic wire enters the wire hole from the cavity 5 and passes through the winding rod 7, and is led out from the outlet at its front end for a certain length, with the end pre-clamped on the coil frame 9.

[0031] The control screw 3 drives the moving seat 4 to move forward, causing the winding rod 7, carrying the electromagnetic wire, to approach the winding seat 13. At this time, the output ends of the cylinders 16 on both sides retract simultaneously, and the push plate 17 and the bending rod 18 retract. The bending rod 18, corresponding to the starting position of the winding rod 7, hooks the electromagnetic wire led out from the winding rod 7, so that the electromagnetic wire is hooked to a suitable position on the winding seat 13. The bending rod 18 is located on one side of the bracket 12 to avoid affecting the winding of the winding rod 7. The end of the winding rod 7 simultaneously reaches a suitable position on one side of the winding seat 13. The winding rod 7 begins to rotate under the drive of the motor, tightly winding the electromagnetic wire onto the winding seat 13. At the same time, the moving seat 4 can slowly retract as needed to control the winding width. After one coil is wound, the output end of the cylinder 16 extends again, causing the bending rod 18 to separate from the electromagnetic wire. Then the moving seat... 4. The winding rod 7 is driven to move backward, leaving the winding area. The winding seat 13 moves downward, carrying the formed coil down into the slot 11 of the holder 10. Then, the electric push rod of the unwinding component is activated, pushing the U-shaped unwinding frame 14 to slide, smoothly pushing the coil off the winding seat 13 so that it is completely wrapped on the teeth of the stator core, completing one coil winding. Then, all structures return to the initial state. The turntable 8 drives the coil frame 9 to rotate by a precise angle (such as 20° or 10°) so that the next tooth to be wound is aligned with the winding seat 13. The winding process is repeated until all coils on the stator core are wound. The stator coil winding process does not require manual intervention. The entire process, from hooking, winding, unwinding to rotation, is carried out continuously without interrupting the equipment, which greatly improves production efficiency and reduces labor costs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
