[0050] The working principle of the present invention is as follows:

[0051] The motor shaft feeding mechanism of the present invention is used in actual use;

[0052] 1. After the wire tray 22 is transported to the planting working position by the wire servo slide rail 21, the wire lifting and positioning mechanism 24 at the bottom lifts and positions the wire tray 22, and then the photoelectric sensor 23 detects whether there is a motor shaft 8 on the stator 221 to be inserted on the surface of the wire tray 22 transported to the position of the wire lifting and positioning mechanism 24. If there is no motor shaft 8, the second step is performed;

[0053] 2. At this time, the tray transfer mechanism 3 starts to work. First, the tray lifting positioning plate 32 pushes up the shaft tray 7 on the full tray stacking mechanism 4 through the tray lifting positioning pin 321. At the same time, the tray remover 42 starts to work. The tray remover cylinder 425 presses down to make the top of the tray remover lifting rod 424 tilt up to make way. At this time, the tray lifting positioning plate 32 moves down with the shaft tray 7 stacked at the bottom. After moving down to the set height, the tray remover cylinder 425 is reset, and the tray remover reset spring 426 is pressed down. Under the action, the tray remover tilting rod 424 is automatically reset, so that it is just stuck on the bottom surface of the second shaft material tray 7 at the bottom, so that after the bottom shaft material tray 7 moves down, the second shaft material tray 7 at the bottom falls on the top of the tray remover tilting rod 424 and continues to be stacked, and the unloading of the shaft material tray 7 on the full material tray stacking mechanism 4 is completed in this cycle. The unloaded shaft material tray 7 is transferred to the planting station between the full material tray stacking mechanism 4 and the empty material tray stacking mechanism 5 together with the tray lifting positioning plate 32;

[0054] 3. At this time, the picking jaw 66 of the transplanting rotary material taking mechanism 6 removes the motor shaft 8 from the shaft material tray 7, and then the picking jaw 66 of the transplanting rotary material taking mechanism 6 rises and rotates 90 degrees, and the picking jaw 66 of the transplanting rotary material taking mechanism 6 descends to put the motor shaft 8 into the shaft stator 221 to be inserted on the surface of the wire body tray 22; then the picking jaw 66 of the transplanting rotary material taking mechanism 6 returns to its original position, and the wire body tray 22 carries the transplanted stator product to the next process;

[0055] 4. When the motor shaft 8 on the shaft material tray 7 is taken out, the empty shaft material tray 7 is further transported to the bottom of the empty material tray placement frame 51 by the material tray transfer mechanism 3, and then the material tray lifting positioning plate 32 pushes the shaft material tray 7 up and into the empty material tray placement frame 51 through the material tray lifting positioning pin 321. At the same time, the loader 52 starts to work, and the pushed shaft material tray 7 lifts the loader tilting rod 524 of the loader 52 upward until the shaft material tray 7 passes into the upper layer. Then, under the action of the loader reset spring 525, the upturned loader tilting rod 524 is reset to a horizontal state. At this time, the material tray lifting positioning plate 32 is removed, and it is lowered and retracted so that the shaft material tray 7 is placed on the surface of the loader tilting rod 524. The material tray lifting positioning plate 32 retreats to its original position with the material tray transfer mechanism 3 to unload the next plate of shaft material tray 7, and the motor shaft is planted in this cycle.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
