As a preferred scheme of the utility model, the size of the guide hole 121 near the side of the iron core 4 is equal to the size of the plug hole, and the guide hole 121 away from the side of the iron core 4 is provided with a taper 122, that is, the size of the port of the guide hole 121 away from the side of the iron core 4 is greater than the size of the plug hole. Through the arrangement of the taper 122, the magnetic steel is conveniently inserted, finally pressed and inserted into the plug hole on the surface of the iron core 4, and the precision of inserting the magnetic steel is ensured.

[0035] The pressure insertion assembly 2 in the utility model is used for inserting the magnetic steel into the plug hole. Specifically, the magnetic steel is grabbed by the mechanical arm 21 driving the clamp jaw 22, and then the magnetic steel is inserted into the plug hole from the guide hole 121.

[0041] Further, the conveying assembly 3 further comprises a conveying assembly 3, the conveying assembly 3 comprises a conveying frame 31 and a jig 32, the conveying frame 31 is arranged at the bottom of the support frame 11, and the jig 32 is arranged on the conveying frame 31, and the iron core 4 is placed on the top of the jig 32.

[0042] Specifically, the top of the jig 32 is used for placing the iron core 4, then the jig 32 is placed on the conveying frame 31 for conveying, and the conveying frame 31 conveys the jig 32 with the iron core 4 to the bottom of the support frame 11.

[0044] This invention uses a limiting component to fix the fixture 32 on the conveyor frame 31. Specifically, a limiting cylinder 332 is located at the bottom of the conveyor frame 31, directly opposite the support frame 11. The action of the limiting cylinder 332 raises the positioning plate 333, causing it to engage with the fixture 32 between the positioning plate 333 and the conveyor frame 31, ultimately causing the iron core 4 to engage with the guide plate 12. The first positioning pin 334 on the positioning plate 333 cooperates with the first positioning hole 321 on the fixture 32, ensuring that the fixture 32 can be stably positioned on the positioning plate 333.

[0048] Furthermore, a check mechanism 34 is provided on the inner side of the conveyor frame 31, and the check mechanism 34 is located at the bottom of the support frame 11.

[0049] Specifically, after the jig 32 passes through the bottom of the support frame 11, the check mechanism 34 can prevent the jig 32 from rebounding, further ensuring the accuracy of the jig 32's delivery position.

[0050] Furthermore, the guide plate 12 is detachably connected to the support frame 11. When the size of the iron core 4 changes, the guide plate 12 with the corresponding hole needs to be replaced to adapt to the iron core 4 of the corresponding size, thus improving the versatility of the entire device. Example 2

[0051] A device for inserting magnets into a motor rotor assembly includes the device for inserting magnets into a motor rotor assembly as described in Embodiment 1.

[0052] In summary, this utility model introduces a device and equipment for inserting magnets into a motor rotor assembly. The specific operating steps are as follows: A fixture 32 with an iron core 4 is conveyed to the bottom of a support frame 11 via a conveyor frame 31. A limiting cylinder 332 actuates to make a positioning plate 333 fit against the fixture 32. The limiting cylinder 332 continues to actuate to make the iron core 4 at the top of the fixture 32 fit against a guide plate 12 on the support frame 11, pressing the iron core 4 firmly against the bottom of the guide plate 12. Simultaneously, a robotic arm 21 drives a gripper 22 to grasp the magnet. A clamping cylinder 23 actuates to cause the gripper 22 to clamp the magnet. When the robotic arm 21 places the magnet at the top of the corresponding guide hole 121, a pressing cylinder 24 actuates a push rod 25 to press the magnet into the insertion hole. This invention provides a guide plate 12 at the top of the iron core 4. The guide hole 121 on the guide plate 12 has a conical structure, which guides the pressing and inserting action of the magnet. This makes it easier for the robotic arm 21 to insert the magnet into the iron core 4, improving the pressing and inserting accuracy of the magnet and increasing the efficiency of magnet insertion.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation.
