Further, referring to fig. 3, as an embodiment of the automatic micro-motor assembling machine provided by the present invention, the micro-motor handling device 70 includes a mounting frame 71, a lifting mechanism 72, and a first driving mechanism 73. The elevating mechanism 72 is provided on the mounting frame 71 and is movable horizontally and linearly. The first driving mechanism 73 is disposed on the mounting frame 71 and is used for driving the lifting mechanism 72 to perform horizontal linear motion, so that the switching of the lifting mechanism 72 between different stations can be realized. Preferably, the first driving mechanism 73 may be provided as a cylinder, the piston rod of which is connected to the lifting mechanism 72. Specifically, the lifting mechanism 72 includes a first mounting base 721, a second driving mechanism 722, a first mounting plate 723, a pressing block 724, and an adsorbing device 725. The first mounting base 721 is connected to the first driving mechanism 73, so that the first mounting base 721 can move horizontally and linearly under the driving of the first driving mechanism 73. The second driving mechanism 722 is disposed on the first mount 721.

For example, when the micro-motor on the waiting station 11 is required to be carried to the end cap riveting station 12, first the first driving mechanism 73 drives the pressing block 724 to move horizontally above the waiting station 11. Then, the second driving mechanism 722 drives the pressing block 724 to descend until the pressing block 724 abuts against the upper surface of the micro-motor, and the magnetic piece can just attract the micro-motor.

The first drive mechanism 73 then drives the lamination block 724 horizontally over the end cap riveting station 12. Finally, the second driving mechanism 722 drives the pressing block 724 to descend until the micro motor is placed on the end cover riveting station 12, and then the riveting operation can be performed. After the end cap riveting, the shaft axial gap measurement and the end cap riveting missing detection are completed, the third driving mechanism 7251 drives the magnetic piece to ascend so as to separate the magnetic piece from the micro motor, then the second driving mechanism 722 drives the pressing block 724 to ascend to the initial position, the first driving mechanism 73 drives the pressing block 724 to horizontally move to the initial position, and the third driving mechanism 7251 drives the magnetic piece to descend to the initial position, so that one working cycle can be completed and the next working cycle can be performed. Preferably, the third driving mechanism 7251 may be provided as an air cylinder. The magnetic member may be made of a magnetic material such as a magnet. It should be noted that the arrangement of the suction device 725 is not limited thereto, and for example, in other preferred embodiments of the present invention, the suction device 725 may be configured as a suction cup, and the suction cup may be connected to a vacuum pump, so as to fix or separate from the micro motor.

The support seat 9157 is provided on the second mounting plate 911. Preferably, both ends of the third elastic member are respectively connected to the push plate 9156 and the support seat 9157, for providing elastic force to move the push plate 9156 toward the direction approaching the spindle axial gap measuring station 13 to contact the driving shaft 913, and to push the driving shaft 913 toward the direction approaching the spindle axial gap measuring station 13. When the sixth driving mechanism 9154 drives the extension shaft 9153 to move in a direction approaching the rotation axis-direction gap measuring station 13, the push plate 9156 rotates in a direction approaching the driving shaft 913 due to the elastic force of the third elastic member, and when the push plate 9156 rotates by a certain angle, the push plate 9156 contacts the driving shaft 913 and pushes the driving shaft 913 to move in a direction approaching the rotation axis-direction gap measuring station 13, so that the clip 916 provided on the driving shaft 913 approaches the rotation axis of the micro motor. Specifically, the sixth driving mechanism 9154 is an air cylinder, and the first elastic member, the second elastic member, and the third elastic member are all springs.

When the sixth driving mechanism 9154 drives the projecting shaft 9153 to move in a direction away from the spindle axial gap measuring station 13 until the boss 901 contacts the push plate 9156, the boss 901 pushes the push plate 9156 to rotate in a reverse direction, so that the push plate 9156 is separated from the driving shaft 913, and the push plate 9156 has no force on the driving shaft 913.
Finally, the driving shaft 913 moves away from the axial gap measuring station 13 of the rotating shaft under the elastic force of the first elastic member, and the measuring meter 92 can measure the moving distance of the rotating shaft away from the axial gap measuring station 13 of the rotating shaft and compare with the initial value, so as to determine whether the axial gap of the rotating shaft meets the requirement.
