Since the orientations of the first shaft end and the second shaft end cannot be unified when the iron core is fed into the guide rail, it is necessary to use the length detection mechanism 8 to detect whether the orientation of the iron core output by the iron core feeding mechanism is correct. The length detection mechanism 8 includes a detection rod 81. A detection mounting frame 82 is fixedly arranged on the frame. A detection sliding seat 83 is arranged on the detection mounting frame 82 in a liftable manner.

In this embodiment, a contact sensor is preferably used. An elastic component is sleeved between the fixed rod 831 and the detection rod 81. In this embodiment, a spring is preferably used.

[0032] During specific operation, the cylinder is used to drive the detection sliding seat 83 to drive the detection rod 81 to descend. At this time, if the second shaft end of the iron core faces upward, the detection rod 81 will be lifted by the second shaft end of the iron core during the downward pressing process until the limiting plate contacts the length detection module 84, and then it is determined that the orientation of the iron core is incorrect. If the first shaft end of the iron core faces upward, the detection rod 81 will not be lifted by the first shaft end of the iron core during the downward pressing process, then it is determined that the orientation of the iron core is correct, thus realizing the automatic detection of whether the orientations of the first shaft end and the second shaft end of the iron core are correct.

[0044] Combined with Figure 3 、 Figure 4 As shown in the figure, the commutator loading component 61 includes a material taking pipe 611, a feeding pipe 612, and an X-axis sliding module 613.

The commutator detection module preferably adopts an infrared sensor. When the commutator detection module detects a commutator, the commutator conveying guide rail does not continue to convey the commutator forward. If the commutator detection module does not detect a commutator, the commutator conveying guide rail continues to convey the commutator, thereby making the conveyance of the commutator more accurate.

[0046] During specific operation, the material taking driving device 617 and the feeding driving device 618 respectively drive the material taking pipe 611 and the feeding pipe 612 to descend, and the air source is turned on to enable the material taking pipe 611 to generate an adsorption force to hold the commutator at the very end on the commutator conveying guide rail 621, while the feeding pipe 612 abuts against the next commutator on the commutator conveying guide rail 621.

Subsequently, the material taking driving device 617 drives the material taking pipe 611 to descend to sleeved the commutator on the second shaft end of the iron core. After turning off the air source, the material taking driving device 617 drives the material taking pipe 611 to ascend.

The feeding driving device 618 drives the feeding pipe 612 to ascend and reset under the drive of the X-axis sliding module. The feeding pipe 612 continues to suck the commutator at the very end of the commutator conveying guide rail 621.

[0048] Furthermore, a qualified detection module 40 is provided at the end of the guide rail 11. In this embodiment, the qualified detection module 40 preferably adopts an infrared sensor, which is used to detect whether the commutator on the iron core is pressed in place.

When the commutator on the iron core is assembled qualifiedly, the screening driving device drives the feed end of the first screening guide groove 71 to be connected with the end of the guide rail, so that the iron core sent out by the guide rail 11 slides into the qualified material box through the first screening guide groove 71. When the commutator of the iron core is assembled unqualifiedly, the screening driving device 73 drives the feed end of the second screening guide groove 72 to be connected with the end of the guide rail 11, so that the unqualified iron core sent out by the guide rail 11 slides into the unqualified material box through the second screening guide groove 72, thus avoiding the mixing of unqualified iron cores and qualified iron cores, and reducing the defective rate of the motor.
