[0034] A plurality of wire wheels 306 are also rotatably mounted on the frame 303. After the winding wire passes through the rear tension regulator 304, it is transmitted through these wire wheels 306 to the gap 5 at the first rotating clamping part 203. A winding wire entrance adjustment group 8 is also provided at the rear end of the connecting plate 3040 fixedly connected to the frame 303. The entrance adjustment group 8 defines a winding wire entrance position on the fully automatic stator winding machine.

[0035] The following introduces the working principle of the fully automatic coil winding machine:

[0036] After the empty stator winding skeleton 208 is installed on the skeleton support seat 2071, it is assembled with the first winding seat 2301 on the left side of the skeleton support seat 2701 and the second winding seat 2501 on the right side to form a winding fixture 207. The winding fixture 207 is rotated and installed between the first rotating clamping part 203 and the second rotating clamping part 205 by controlling the first cylinder 206. Then, the winding passes through the inlet adjustment group 8 provided at the rear of the frame 303, and the winding passes through the wire feeding mechanism 3. The wire goes through the channel formed between the upper adjusting wheel 3041 and the lower adjusting wheels 3042 to reach the tension adjuster 304, and then passes the winding wire through the wire wheel 306 above the tension adjuster 304 and reaches the remaining wire wheels 306 on the frame 303. The winding wire comes to the clamping mechanism 6, and the winding wire is clamped to the notch 5 of the clamping mechanism 6 by the third cylinder 7. After closing the protective cover 101 and setting the relevant working information on the operating box 102, the fully automatic stator winding machine is started, and the first motor 204 and the second motor 300 of the winding machine start to run.

[0037] The first motor 204 starts to rotate clockwise, driving the steering shaft 2042 on the top to rotate together, so that the winding mechanism 2 starts to rotate clockwise around a horizontal axis. At the same time, the ball screw 3001 on the second motor 300 starts to rotate, driving the slider 3002 and the wire feeding mechanism 3 to move rightward as a whole.

[0038] When the ball screw 3001 rotates clockwise, the first winding seat 2031 of the winding mechanism 2 begins to be wound with some wire. When the wire passes through the convex pin provided on the first winding seat 2031 and reaches the left stator winding frame 208, the ball screw 3001 rotates counterclockwise, driving the slider 3002 to move a small distance to the left, so that the wire is stuck in the left starting position of the left stator winding frame 208. The ball screw 3001 is adjusted to rotate clockwise at high speed, driving the wire feeding mechanism 3 to move to the right on the track 302, so that the wire is wound on the rotating left stator winding frame 208 at high speed.

[0039] After the wire is wound on the left stator winding frame 208, the ball screw 3001 is adjusted to rotate slowly clockwise, driving the wire feeding mechanism 3 to a position parallel to the middle stator winding frame 208, and the ball screw 3001 rotates counterclockwise, driving the slider 3002 to move a small distance to the left, so that the winding is stuck in the left starting position of the middle stator winding frame 208, and then the ball screw 3001 is adjusted to rotate clockwise at high speed, driving the wire feeding mechanism 3 to move to the right on the track 302, so that the rotating middle stator winding frame 208 is wound with wire at high speed.

[0040] After the wire is wound on the middle stator winding frame 208, the ball screw 3001 is adjusted to rotate clockwise at a slow speed, driving the wire feeding mechanism 3 to a position parallel to the right stator winding frame 208, and the ball screw 3001 rotates counterclockwise, driving the slider 3002 to move a small distance to the left, so that the wire is stuck in the starting position on the left side of the right stator winding frame 208, and then the ball screw 3001 is adjusted to rotate clockwise at a high speed, driving the wire feeding mechanism 3 to move rightward on the track 302, so that the wire is wound on the rotating right stator winding frame 208 at a high speed.

[0041] Subsequently, the ball screw 3001 is adjusted to rotate slowly clockwise, driving the wire feeding mechanism 3 to slowly wind the wire around the second winding seat 2051 for one circle. At this time, a layer of wire is wound on the stator winding frame 208 on the winding fixture 207. The ball screw 3001 rotates counterclockwise again, driving the wire feeding mechanism 3 to move to the left by a certain distance, and clamps the wire on one side of the convex pin on the second winding seat 2051. Then the clockwise rotation of the first motor 204 is adjusted to counterclockwise rotation, and rotated by a certain angle. Then the ball screw 3001 rotates slowly clockwise, driving The wire feeding mechanism 3 is displaced to the right by a certain distance, so that the winding wire follows the wire feeding mechanism 3 to the other side of the convex pin on the second winding seat 2051 and is wound around the convex pin of the second winding seat 2051. Then the first motor 204 rotates counterclockwise, so that the winding mechanism 2 rotates counterclockwise, and the ball screw 3001 then rotates clockwise to allow the wire feeding mechanism 3 to wind the wire around the second winding seat 2051 for several turns, and then the ball screw 3001 rotates counterclockwise slowly, and the wire feeding mechanism 3 starts to move to the left as a whole through the counterclockwise rotation of the ball screw 3001.

[0042] When the wire feeding mechanism 3 comes to be parallel to the right stator winding frame 208, the ball screw 3001 rotates clockwise, driving the slider 3002 to move a small distance to the right, so that the winding is stuck in the right starting position of the right stator winding frame 208. The ball screw 3001 is adjusted to rotate counterclockwise at high speed, driving the wire feeding mechanism 3 to move to the left on the track 302, so that the winding is wound on the rotating right stator winding frame 208 at high speed.

[0043] After the wire is wound on the right stator winding frame 208, the ball screw 3001 is adjusted to rotate counterclockwise at a slow speed, driving the wire feeding mechanism 3 to a position parallel to the middle stator winding frame 208, and the ball screw 3001 rotates clockwise, driving the slider 3002 to move a small distance to the right, so that the wire is stuck in the right starting position of the middle stator winding frame 208, and then the ball screw 3001 is adjusted to rotate counterclockwise at a high speed, driving the wire feeding mechanism 3 to move to the left on the track 302, so that the wire is wound on the rotating middle stator winding frame 208 at a high speed.

[0044] After the wire is wound on the middle stator winding frame 208, the ball screw 3001 is adjusted to rotate counterclockwise at a slow speed, driving the wire feeding mechanism 3 to a position parallel to the left stator winding frame 208. The ball screw 3001 rotates clockwise, driving the wire feeding mechanism 3 to move a small distance to the right, so that the wire is stuck in the right starting position of the left stator winding frame 208. Then the ball screw 3001 is adjusted to rotate counterclockwise at a high speed, driving the wire feeding mechanism 3 to move to the left on the track 302, so that the wire is wound on the rotating left stator winding frame 208 at a high speed.

[0045] When several stator winding frames 208 on the winding tooling 207 are wound with the second layer of winding, the ball screw 3001 is adjusted to rotate slowly counterclockwise, driving the wire feeding mechanism 3 to move slowly to the left, and winding the winding around the first winding seat 2031 for one circle. At this time, the wire clamping mechanism 6 located on the side of the first rotating clamping part 203 releases the clamped starting end of the winding, and the ball screw 3001 continues to rotate slowly counterclockwise to bring the winding back to the notch 5. At the same time, the second circle of winding is wound on the first winding seat 2031.

[0046] When the winding enters the gap 5, the wire clamping mechanism 4 and the wire cutting mechanism 6 in the gap 5 start to work, clamping the returning winding at the gap 5 and cutting the winding returning from the winding mechanism 2 at the same time, and the cutter head of the wire cutting mechanism 4 automatically bounces back. At this time, the original winding starting end on one side of the cutter head and the two ends of the cut end of the winding returning from the winding mechanism 2 are scattered in the gap 5, while the wire clamping mechanism 4 on the other side of the gap 5 still clamps the starting end of the new winding at the rear. At this time, the full-automatic stator winding machine stops running.

[0047] The worker opens the protective cover 101 and removes the winding jig 207 from the machine under the control of the first cylinder 206. Then, he removes several stator winding skeletons 208 that have been wound with two layers of winding from the winding jig 207, places empty stator winding skeletons 208 on the winding jig 207, and installs the winding jig 207 between the first rotating clamping part 203 and the second rotating clamping part 205 again. Then, he closes the protective cover 101, and the full-automatic stator winding machine starts to operate again to continue winding.

[0048] Attached Figure 4 As shown, after several groups of stator winding bobbins 208 with wound wires are taken off from the winding tooling fixture 207, these stator winding bobbins 208 with wound wires are installed on the stator core 9, and the manufacture of a stator assembly can be completed.
