[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides an automotive generator rotor assembly device, such as... Figures 1 to 9 As shown, the device includes a worktable 1, a stator core support mold 2, a cylinder 3, guide arms 4, and an adjustment mechanism. The stator core support mold 2 is mounted on the worktable 1 for placing workpieces. The cylinder 3 is mounted on the worktable 1, and two guide arms 4 are mounted on the top of the cylinder 3 for controlling the movement of the two guide arms 4. A button is mounted on the worktable 1, and a control panel 8 is mounted on the top of the worktable 1 for controlling the operation of the cylinder 3, the two guide arms 4, and the stator core support mold 2. A drive component is mounted at the bottom of the cylinder 3 for controlling the rotation of the two guide arms 4. The drive component, the cylinder 3, and the guide arms 4 are located on opposite sides of the stator core support mold 2. The drive component is a motor 9, which is fixedly connected inside the worktable 1. The output end of the motor 9 is fixedly connected to the bottom of the cylinder 3. The adjustment mechanism is set on the cylinder 3 and two guide arms 4. The adjustment mechanism includes a connecting ring 5, a slot 7, a limiting groove, and a limiting structure. The connecting ring 5 is set between the two guide arms 4, and a first electric push rod 6 is fixedly connected to both the upper and lower sides of the connecting ring 5. The slot 7 is opened on the two guide arms 4, and the end of the first electric push rod 6 away from the connecting ring 5 is inserted into the slot 7. The limiting groove is opened at the top of the cylinder 3 and is connected to the slot 7. A limiting structure is set inside the limiting groove and the slot 7.

[0021] When the stator core support mold 2 is working, it can expand and contract radially. After being inserted into the stator, it expands to fit the inner wall of the stator slot, fixes the stator position, and prevents displacement and deformation during wire insertion. At the same time, the guide groove on its surface is aligned with the stator slot opening, providing a guide channel for the wire harness to enter the slot. After the wire is inserted, it contracts to facilitate the removal of the stator. Through the extension and retraction of the cylinder 3 rod, the two guide arms 4 at the top move up and down, realizing the alignment and pushing action of the guide arms 4 with the wire harness and stator support mold.

[0022] According to the specifications (slot pitch, width) of the stator to be embedded, the adjustment parameters are set through the control panel 8, and the first electric push rod 6 is activated: the electric push rod extends or retracts, pushing the two guide arms 4 to move along the slot 7, adjusting the distance between the two guide arms 4 until it matches the stator slot pitch and width. After the adjustment is in place, the limiting structure automatically snaps into the limiting slot and slot 7, locking the position of the guide arms 4 to prevent displacement, thus completing the specification adaptation.

[0023] When the operator places the stator core to be embedded onto the stator core support mold 2 on the workbench 1 and presses the start button on the workbench 1, the control panel 8 issues a command, the stator core support mold 2 expands radially, and the multi-lobed expansion block fits against the inner wall of the stator slot to fix the stator position. At the same time, the guide groove on the support mold is precisely aligned with the stator slot opening to prepare for the wire harness to enter the slot. The control panel 8 controls the motor 9 to drive the cylinder 3 and the two guide arms 4 at the top to rotate synchronously, adjusting the angle of the guide arms 4 so that the inclined surface at the front end of the guide arm 4 faces the wire harness, ensuring that the inclined surface can accurately fit the outside of the wire harness. Then, the control panel 8 controls the cylinder 3 to extend, driving the two guide arms 4 to descend synchronously until the inclined surface at the front end of the guide arm 4 gently fits the wire harness, completing the alignment. After alignment, the control panel 8 controls the cylinder 3 to continue to extend smoothly, driving the two guide arms 4 to descend synchronously. The inclined surface at the front end of the guide arm 4, by virtue of its tilt angle, gathers and aligns the scattered wire harness, while generating an inward component force to guide the wire harness to slide smoothly along the guide groove of the stator core support mold 2, gradually pushing the wire harness into the stator groove. After the coil is completely in the groove, the cylinder 3 retracts, driving the guide arm 4 to rise and reset; the motor 9 drives the guide arm 4 to rotate, retracting to a safe position to avoid interference with the unloading; the stator core support mold 2 retracts radially, disengaging from the inner wall of the stator groove; the operator presses the button to remove the stator with the embedded wire.

[0024] When the guide arm 4 wears out, the first electric push rod 6 is activated to disconnect it from the slot 7 on one of the guide arms 4, thus disconnecting the limiting structure from the cylinder 3. The two guide arms 4 are rotated to switch positions, and then the first electric push rod 6 is used to connect them to the slot 7 again, and the limiting structure is used to connect them to the cylinder 3 again for reuse. At the same time, the switched guide arm 4 automatically retracts to a safe position, preventing it from touching the mold or scratching the line, thus preventing interference and improving work efficiency.

[0025] like Figures 8 to 9 As shown, there are four slots 7 and four first electric push rods 6. The limiting structure is located in the limiting groove and slot 7 on the left and right sides of the two guide arms 4. The limiting structure includes a limiting block 10 and a first spring 11. The bottom of the limiting block 10 is slidably connected to the inner wall of the limiting groove and slot 7. The side of the limiting block 10 away from the limiting groove is connected to the inner wall of the slot 7 through the first spring 11. The first electric push rod 6 is located at one end of the slot 7. The side of the limiting block 10 away from the first spring 11 is both inclined. The inclined surface of the first electric push rod 6 fits against the inclined surface of the limiting block 10.

[0026] In the initial state, the first spring 11 always pushes the limiting block 10 outward, so that one end of the limiting block 10 passes through the slot 7 and is inserted into the limiting groove. During the winding operation, the guide arm 4 will not deviate or shake under the force and vibration, ensuring that the inclined surface of the push head 16 is always aligned with the wire harness and the mold guide groove. When it is necessary to replace the guide arm 4, the four first electric push rods 6 retract synchronously. The inclined surface of the first electric push rod 6 no longer presses against the inclined surface of the limiting block 10, and the first spring 11 is no longer compressed, thereby driving the limiting block 10 to move backward into the slot 7. When the limiting block 10 disengages from the limiting groove, it releases the constraint on the guide arm 4. At this time, the two guide arms 4 are rotated to change their positions, so that the worn guide arm 4 rotates to the rear side of the cylinder 3. Then, the first electric push rod 6 extends, so that the inclined surface of the first electric push rod 6 fits against the inclined surface of the limiting block 10, compressing the first spring 11 and pushing the limiting block 10 to slide and reset along the limiting groove. The limiting block 10 is re-engaged into the limiting groove, automatically locking the position of the guide arm 4 again, and then it can continue to be used, which facilitates the improvement of replacement efficiency.

[0027] like Figures 2 to 3 As shown, a limiting component is provided on the outer side of the bottom end of the cylinder 3. The limiting component includes a mounting base 12 and a telescopic support rod 13. The mounting base 12 is fixedly connected to the bottom end of the cylinder 3. The bottom of the mounting base 12 is rotatably connected to one side of the worktable 1. The mounting base 12 connects the cylinder 3 and the worktable 1, and plays a role in assisting in fixing the cylinder 3, dispersing the force on the cylinder 3, and reducing the deformation of the cylinder 3 caused by the pressure of the guide arm 4. A telescopic support rod 13 is provided on the top of the mounting base 12. The top of the telescopic support rod 13 is inserted into the bottom of the guide arm 4. The bottom of the fixed end of the telescopic support rod 13 is fixedly connected to the mounting base 12. A second spring 14 is fixedly connected inside the fixed end of the telescopic support rod 13. The fixed end of the telescopic support rod 13 is connected to the telescopic end of the telescopic support rod 13 through the second spring 14.

[0028] The telescopic support rod 13 is installed through the mounting base 12. The telescopic support rod 13 provides bottom auxiliary support for the guide arm 4, shares the force on the top of the cylinder 3, and prevents the guide arm 4 from bending or shifting downward due to the reaction force of the front push coil. The telescopic end can extend and retract flexibly to adapt to the lifting and lowering action of the guide arm 4 without affecting the normal movement of the guide arm 4. When the guide arm 4 pushes the coil downward during winding, it will be subject to the reaction force of the coil. The second spring 14 can absorb part of the impact force through compression and rebound, reducing the vibration of the guide arm 4 and the cylinder 3, and avoiding wear and deformation of the components. When the guide arm 4 rises, the spring rebounds and pushes the telescopic end to extend synchronously, always in contact with the bottom of the guide arm 4. At the same time, the telescopic end is inserted into the bottom of the guide arm 4, which can be quickly disassembled and positioned, facilitating the maintenance and replacement of the guide arm 4.

[0029] like Figures 4 to 5As shown, the middle part of the two guide arms 4 is rotatably connected to the top of the cylinder 3, and the two guide arms 4 are arranged in a rotationally symmetrical manner with respect to the center of the cylinder 3. Both guide arms 4 are provided with a replacement structure for replacing the damaged guide arm 4. The end of the two guide arms 4 away from the cylinder 3 is provided with an inclined surface for conforming to the direction and automatically gathering the wire harness. Both guide arms 4 include a connecting arm 15 and a push head 16. A replacement structure is set at the connection between the connecting arm 15 and the push head 16. The replacement structure includes a connecting block 17, a third spring 18, and a connecting rod 19. A connecting block 17 is provided on the side of the connection between the connecting arm 15 and the push head 16. The connecting block 17 is connected to the connecting arm 15 through the third spring 18. The connecting rod 19 is fixedly connected to the side of the connecting block 17 away from the third spring 18. The connecting rod 19 is inserted into the push head 16. A second electric push rod 20 is fixedly connected inside the connecting arm 15. The end of the second electric push rod 20 passes through the push head 16 and is inserted into the connecting rod 19. A fixing member is provided on the telescopic end of the second electric push rod 20. The fixing member is located inside the end of the connecting arm 15 near the push head 16 and is used to fix the connecting block 17, the connecting arm 15, and the push head 16 again.

[0030] When cylinder 3 drives guide arm 4 to descend as a whole, the inclined surface of push head 16 first contacts the outer side of the wire harness. Utilizing the inclination angle of the inclined surface, an inward converging force is generated, smoothly conforming to the wire harness and automatically gathering loose wires. The wire harness is then neatly guided into the guide groove of stator core support mold 2, and then smoothly pushed into the stator wire groove as guide arm 4 descends, avoiding sharp corners that could harden the wire harness insulation. Connecting block 17 drives connecting rod 19 to insert into the side hole of push head 16, completing the initial lateral positioning of connecting arm 15 and push head 16. The second electric push rod 20 extends, its end passing through push head 16 and axially inserting into connecting rod 19, restricting the push head 16's back-and-forth movement and completing axial locking. After the second electric push rod 20 is in position, the fixing component on it moves, fixing the connecting block 17, connecting arm 15, and push head 16 inside the connecting arm 15. When the push head 16 needs to be replaced, the second electric push rod 20 is controlled to retract, first withdrawing the connecting rod 19, releasing the axial lock, so that the fixing component is unlocked simultaneously. The connecting block 17 is pulled laterally to stretch the third spring 18, causing the connecting rod 19 to withdraw laterally from the push head 16. The worn or deformed push head 16 can be directly removed and a new push head 16 can be installed. The connecting block 17 is released, the third spring 18 rebounds, and the connecting rod 19 is reinserted into the push head 16. The second electric push rod 20 extends and tightens again, the fixing component is locked a second time, and the working state is immediately restored.

[0031] like Figures 6 to 7As shown, the fixing component includes a movable block 21, a push rod 22, a compression spring 23, and a fixed rod 24. The movable block 21 is fixedly connected to the telescopic end of the second electric push rod 20. The push rod 22 is fixedly connected to one side of the movable block 21. A protrusion is provided at the bottom end of the push rod 22, and a fixed rod 24 is provided at the protrusion. The side of the fixed rod 24 near the protrusion is inclined, and the protrusion is located at the inclined surface. The fixed rod 24 is connected to the inner wall of the connecting arm 15 through the mounting plate and the compression spring 23. The fixed rod 24 passes through the connecting arm 15 and is inserted into the connecting block 17.

[0032] In the initial state, the compression spring 23 is compressed, pushing the fixing rod 24 into the holes of the connecting block 17 and the connecting arm 15 to achieve initial fixation, limiting the relative displacement of the two and preventing the connecting arm 15 from shifting and the push head 16 from misaligning. When it is necessary to replace the push head 16 with a different specification, the second electric push rod 20 retracts, driving the moving block 21 to move backward, so that the protrusion of the push rod 22 no longer presses against the inclined surface of the fixing rod 24. The compression spring 23 stretches, causing the fixing rod 24 to be pulled out of the hole and the lock is released. After the replacement is completed, the second electric push rod 20 extends again, pushing the moving block 21 and the push rod 22 to reset. The fixing rod 24 is reinserted into the hole, and the compression spring 23 rebounds, completing the fixation. This ensures that the guide arm 4 and the push head 16 do not shift or loosen during operation, while facilitating later replacement and maintenance. It is compatible with the overall winding process of the equipment and works in synergy with the second electric push rod 20, the guide arm 4, and the stator support mold to ensure winding quality and efficiency.

[0033] Working principle of this invention: Reference Figures 1 to 9As shown, during use, the stator core to be embedded is placed on the stator core support mold 2 on the workbench 1. The start button on the workbench 1 is pressed, and the control panel 8 issues a command. The stator core support mold 2 expands radially, and the multi-lobed expansion blocks fit against the inner wall of the stator slot, fixing the stator position. Simultaneously, the guide groove on the support mold is precisely aligned with the stator slot opening, preparing for the wire harness insertion. The control panel 8 controls the motor 9 to drive the cylinder 3 and the two guide arms 4 at the top to rotate synchronously, adjusting the angle of the guide arms 4 so that the inclined surface at the front end of the guide arms 4 faces the wire harness, ensuring that the inclined surface can accurately fit against the outside of the wire harness. Then, the control panel 8 controls the cylinder 3 to extend, driving the two guide arms 4 to descend synchronously. The telescopic support rod 13 retracts, compressing the second spring 14 until the inclined surface at the front end of the guide arms 4 gently fits against the wire harness, completing the alignment. After alignment, the control panel 8 controls the cylinder 3 to continue to extend smoothly, driving the two guide arms 4 to descend synchronously. The inclined surface at the front end, by virtue of its tilt angle, gathers and aligns the scattered wire bundle, while simultaneously generating an inward force to guide the wire bundle to slide smoothly along the guide groove of the stator core support mold 2, gradually pushing the wire bundle into the stator slot. After the coil is fully inserted into the slot, the cylinder 3 retracts, driving the guide arm 4 and the telescopic support rod 13 to rise and reset, and the second spring 14 stretches; then the motor 9 drives the guide arm 4 to rotate, retracting to a safe position to avoid interference with the unloading; the stator core support mold 2 retracts radially, disengaging from the inner wall of the stator slot; the operator presses the button to remove the stator with the embedded wire.

[0034] When the entire guide arm 4 needs to be replaced, the telescopic support rod 13 retracts to no longer restrict the guide arm 4. The four first electric push rods 6 retract synchronously. The inclined surface of the first electric push rod 6 no longer presses against the inclined surface of the limiting block 10, and the first spring 11 is no longer compressed. This causes the limiting block 10 to move backward into the slot 7. The limiting block 10 disengages from the limiting groove, releasing the restriction on the guide arm 4. At this time, the two guide arms 4 are rotated to change their positions, so that the worn guide arm 4 rotates to the rear side of the cylinder 3. Then, the first electric push rod 6 extends, so that the inclined surface of the first electric push rod 6 fits against the inclined surface of the limiting block 10, compressing the first spring 11 and pushing the limiting block 10 to slide back along the limiting groove. The limiting block 10 re-locks into the limiting groove and automatically locks the position of the guide arm 4 again, allowing the replaced guide arm 4 to be used.

[0035] When it is necessary to replace the guide arm 4 with one of different specifications, the second electric push rod 20 is activated to retract, causing the moving block 21 to move backward. This prevents the protrusion of the push rod 22 from pressing against the inclined surface of the fixed rod 24, and the compression spring 23 is stretched, causing the fixed rod 24 to be pulled out of the hole and the lock is released. The connecting block 17 is pulled laterally, causing the third spring 18 to stretch and the connecting rod 19 to be pulled out laterally from the push head 16. The worn or deformed push head 16 can then be removed directly and a new push head 16 can be installed. The connecting block 17 is released, the third spring 18 rebounds, and the connecting rod 19 is reinserted into the push head 16. This causes the second electric push rod 20 to extend and tighten again, locking the fixing part a second time and immediately restoring the working state.

[0036] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
