[0106] In an embodiment of the present utility model, the supporting mechanism 200 further includes:

[0107] The carrier plate is slidably disposed on the frame 100, and a plurality of nozzle assemblies 210 are spaced apart along a first direction;

[0108] The seventh driving assembly is disposed on the frame 100 , and drives the carrier to move along the first direction.

[0109] Specifically, the nozzle assembly 210 is arranged on the carrier plate, and the carrier plate is driven by the seventh driving assembly to be arranged at intervals along the first direction on the frame 100. A plurality of second sensors 110 are arranged between the carrying mechanism 200 and the conveying mechanism 500, and the plurality of second sensors 110 are arranged at intervals along the first direction. After the clamping assembly 510 clamps the unwound rotor and moves toward the direction of the winding mechanism 400, when each second sensor 110 senses the workpiece (rotor), the seventh driving assembly drives the carrier plate to move toward the direction of the conveying mechanism 500, and the carrier plate moves to the bottom of the clamping assembly 510. By adjusting the position of the manipulator 511 that clamps the unwound rotor, each manipulator 511 corresponds to a nozzle assembly 210. At this time, the manipulator 511 is driven to descend by the fifth driving assembly 550 to place the rotor on the nozzle assembly 210. The manipulator 511 releases the rotor and drives the carrier plate to move to the middle set assembly by the seventh driving assembly. The workpiece 310 is below the workpiece 310. At this time, the middle sleeve assembly 310 is driven to descend by the second driving assembly 330 to cover the commutator of the rotor and wait for the winding mechanism 400 to wind the rotor. After the winding is completed, the seventh driving assembly drives the carrier to move toward the direction of the conveying mechanism 500 and below the clamping assembly 510. At this time, one group of clamping assemblies 510 of the conveying mechanism 500 clamps the unwound rotor, and one group of clamping assemblies 510 does not clamp the workpiece. The clamping assemblies 510 that do not clamp the workpiece are driven by the fifth driving assembly 550 and the sixth driving assembly 560 to move to the top of the nozzle assembly 210, and clamp the wound rotor. Then, the clamping assembly 510 that clamps the unwound rotor is moved to the top of the nozzle assembly 210 by the fifth driving assembly 550 and the sixth driving assembly 560, and the rotor is placed on the nozzle assembly 210, waiting for the next winding, so as to realize the conveying of the wound rotor and the unwound rotor, thereby improving the work efficiency. The seventh driving component can be a linear driving component such as a cylinder, a hydraulic cylinder or an electric telescopic component.

[0110] In addition, the frame 100 is also provided with an accordion cover 220 to prevent dust and protect the supporting mechanism 200 from entering and affecting the operation of the supporting mechanism 200.

[0111] In an embodiment of the present utility model, the rotor winding machine further includes a conveying mechanism 600, and the conveying mechanism 600 includes:

[0112] A feeding conveyor line 610, on which a tray 670 for placing an unwound rotor is disposed, and which moves along a second direction;

[0113] The storage conveyor line 620 is parallel to the feeding conveyor line 610;

[0114] The first transfer assembly 640 is used to transfer the tray 670 on the feeding conveyor line 610 to the storage conveyor line 620 to wait for the conveying mechanism 500 to carry it;

[0115] The second transfer assembly 641 is used to transfer the tray 670 on the stock material conveying line 620 to the stock material conveying line 620 .

[0116] Please refer to Fig.10 and Fig.11 A conveying mechanism 600 is installed on the frame 100. The conveying mechanism 600 includes a feeding conveyor line 610 and a storage conveyor line 620 arranged in parallel, and also includes a first transfer component 640 and a second transfer component 641. The first transfer component 640 and the second transfer component 641 are arranged on the storage conveyor line 620. The feeding conveyor line 610 and the storage conveyor line 620 move along the second direction. The feeding conveyor line 610 is used to transport a pallet 670 with a rotor placed thereon. The rotor that is not wound is transported at the front end in the transport direction. The first transfer component 640 transfers the pallet 670 to the storage conveyor line 620, waiting for the transport mechanism 500 to transport it. The empty pallet 670 after transport continues to be on the storage conveyor line 620. After winding is completed, the transport mechanism 500 places the wound rotor on the empty pallet 670, and transfers the wound rotor and the pallet 670 to the feeding conveyor line 610 through the second transfer component 641, and flows to the next process.

[0117] It should be noted that the transport mechanism 500 clamps the rotor with completed winding and moves it to the storage conveyor line 620. The two side-by-side manipulators 511 descend, one of which clamps the rotor with completed winding and places it in the empty pallet 670, and the other manipulator 511 clamps the rotor without winding on the pallet 670 and leaves the empty pallet 670. At this time, the storage conveyor line 620 drives the pallet 670 to continue to move forward, the pallet 670 with the rotor moves forward one station, and the empty pallet 670 moves to the next station. The fourth drive assembly drives the clamp 670 to move forward one station, and the empty pallet 670 moves forward one station. The picking component 510 continues to move along the first direction toward the conveying mechanism 600, that is, the two manipulators 511 in the second row move to above the tray 670, one manipulator 511 clamps the rotor, and the other manipulator 511 places the clamped wound rotor on the empty tray 670, and repeats the previous process until one group of manipulators 511 clamps the rotor, and the other group of manipulators 511 places all the wound rotors on the empty tray 670. At this time, the fourth drive component drives the clamping component 510 to move toward the winding mechanism 400.

[0118] Among them, the first transfer component 640 and the second transfer component 641 have the same structure, including a stand 642 and a gripper 643, the stand 642 is set on the frame 100, the gripper 643 is set on the stand 642, and moves along the three directions of X, Y, and Z on the stand 642, and the gripper 643 is controlled by a two-way cylinder to grab and transport the pallet 670 and the rotor. Specifically, a grabbing portion 671 is set on the pallet 670, and the grabbing portion 671 is used to support the rotor. A grabbing groove 672 is set on the outer periphery of the grabbing portion 671, and the gripper 643 is in the grabbing groove 672 to transfer the pallet 670.

[0119] Among them, the conveying mechanism 600 also includes a reflux conveyor line 630, which is parallel to the feeding conveyor line 610. The reflux conveyor line 630, the feeding conveyor line 610 and the storage conveyor line 620 run through different processes. The feeding conveyor line 610 and the reflux conveyor line 630 have opposite moving directions. When the rotor is processed in the last process, the empty pallet 670 is transferred to the reflux conveyor line 630 and returns to the first process with the reflux conveyor line 630 to process a new round of rotors.

[0120] In an embodiment of the present utility model, the conveying mechanism 600 further includes:

[0121] The first sensor 650 is disposed on the material storage conveying line 620 to sense the tray 670;

[0122] The lifting assembly 660 is disposed on the material storage conveying line 620 to lift up the tray 670 when the first sensor 650 senses the tray 670 .

[0123] Specifically, please refer to Fig.10 A first sensor 650, a lifting assembly 660 and a blocking member are provided on the stock conveying line 620. When the first sensor 650 senses the tray 670, the blocking member rises. At this time, the lifting assembly 660 moves upward and lifts the tray 670, blocking the tray 670 from continuing to flow forward with the stock conveying line 620 and waiting for the transport mechanism 500 to transport it. In addition, a first limiting member 673 is provided on the tray 670, and a second limiting member 680 is provided on the stock conveying line 620. When the lifting assembly 660 lifts the tray 670, the first limiting member 673 rises and abuts against the second limiting member 680 to prevent the rising height process from affecting stability.

[0124] The lifting component 660 may be a linear drive component such as a cylinder, and the output end of the lifting component 660 extends upward to lift the tray 670.
