[0036] The lead wire puncture test mechanism and the lead wire shearing mechanism are located around the through hole on the workbench A.

[0037] The stator clamping and lifting mechanism includes a chuck 1, a first lifting driver 2, and a fixing block 3. The fixing block 3 is fixed to the lower end of the worktable A. The chuck 1 is directly below the through hole of the worktable A. The area of ​​the through hole on the worktable A is larger than the area of ​​the top of the chuck 1. A third slide rail 3a is fixed on the fixing block 3. The chuck 1 slides with the third slide rail 3a. The chuck 3 is also connected to the first lifting driver 2. The first lifting driver 2 drives the chuck 1 to move upward or downward along the third slide rail 3a. The chuck 1 enters the inner hole of the stator to tighten the stator.

[0039] The lead wire puncture test mechanism includes a first test block 4, a second test block 5, a first mounting base 6, a second mounting base 7, and a first drive system. The first drive system is set on the workbench A. The first mounting base 6 is connected to the first test block 4, and the second mounting base 7 is connected to the second test block 5. The first test block 4 and the second test block 5 are located at the two ends of the through hole on the workbench A, respectively, and cooperate with the first drive system.

The first test block 4 is connected to a first pressure block 4a, and the second test block 5 is connected to a second pressure block 5a. Both the first pressure block 4a and the second pressure block 5a have grooves for hiding the test wires.

[0040] The first drive system includes a first slide rail 8, a first slider 9, a connecting rod 10, and a drive cylinder 11. There are two sets of first slide rails 8, each set of which is slidably connected to the first slider 9 at both ends. The two sets of first slide rails 8 are symmetrically fixed at both ends of the through hole on the worktable A. There are two sets of connecting rods 10, each set of which is connected to a first slider 9 at both ends and is perpendicular to any one of the first slide rails 8.

Both ends of the drive cylinder 11 have piston rods, and the two connecting rods 10 are respectively connected to the two ends of the drive cylinder 11.

After reaching the designated position, the stator lead wire is punctured and detected.

[0041] The post-test lead wire cutting mechanism includes a wire guiding fork 12, a second drive system, and a cutting system. The wire guiding fork 12 has a groove on its side. The wire guiding fork 12 cooperates with the cutting system, and the cutting system cooperates with the second drive system.

[0042] The second drive system includes a second slide rail 13, a second slider 14, a second connecting seat 15, and a second cylinder 16. There are two sets of second slide rails 13, and the same end of each set of second slide rails 13 is connected to a second slider 14.

The moving blade 17 is fixed to the moving blade holder 18 and is located on one side of the through hole on the worktable A. The moving blade holder 18 is connected to the second slider 14 and fixed to the second connecting seat 15. The fixed blade holder 20 is set on the worktable A and is located on the other side of the through hole on the worktable A. The fixed blade 19 is fixed on the fixed blade holder 20, and the wire guide fork 12 is fixed on the fixed blade holder 20.

[0044] After the lead wire cutting mechanism is activated, the second cylinder 16 drives the second connecting seat 15 to push the moving knife seat 18 along the second slide rail 13 toward the fixed knife seat 20. When the moving knife 17 approaches the fixed knife 19, the wire fork 12 presses the stator lead wire against the side of the moving knife seat 18 and clamps the lead wire. At this time, the moving knife 17 and the fixed knife 19 cut the lead wire under the interaction of forces. The stator is lowered along with the stator clamping lifting mechanism. After the stator is taken away by the staff or robot, the cutting system is reset and the cut lead wire is released to prevent the cut lead wire from falling into the stator winding.

[0045] This utility model also includes a wire alignment and wire handling mechanism, which is fixed on the workbench A and cooperates with the stator clamping and lifting mechanism.

[0046] The cable alignment and cable management mechanism includes a third cylinder 21, a fixed base 22, a finger cylinder 23, and a cable management clamp 24.

The third cylinder 21 is connected to the finger cylinder 23, and the finger cylinder 23 is connected to the cable management clamp 24. The finger cylinder 23 and the cable management clamp 24 are located above the drive cylinder 11.

[0047] The finger cylinder 23 drives the cable clamp 24 to open. After the stator clamping and lifting mechanism drives the stator to rise, the third cylinder 21 operates, and the piston rod of the third cylinder 21 extends, driving the finger cylinder 23 and the cable clamp 24 to move towards the through hole on the worktable A. Then, the finger cylinder 23 drives the cable clamp 24 to clamp the stator lead wire. Subsequently, the stator clamping and lifting mechanism drives the stator to descend in a straight line, and the stator lead wire clamped by the cable clamp 24 is straightened by the cable clamp 24. After the stator clamping and lifting mechanism descends to the set position, the finger cylinder 23 drives the cable clamp 24 to open, and the piston rod of the third cylinder 21 retracts, causing the finger cylinder 23 and the cable clamp 24 to return to the initial position.

[0048] It also includes a buffer mechanism, which is set on the workbench A. The buffer mechanism includes a positioning block 25, a first connecting seat 26, a guide rod 27, and a spring 28. The positioning block 25 is connected to the first connecting seat 26. The positioning block 25 has a through hole. One end of the guide rod 27 passes through the through hole on the positioning block 25 and is fitted with a clearance fit. The other end of the guide rod 27 is fixed to the cable fork 12. The spring 28 is sleeved on the guide rod 27. One end of the spring 28 abuts against the positioning block 25, and the other end of the spring 28 abuts against the cable fork 12. When the moving knife holder 18 is engaged with the cable fork 12, the cable fork 12 is pushed back by pressure, and the spring 28 is compressed. When the moving knife holder 18 is separated from the cable fork 12, the spring 28 releases the accumulated elastic potential energy, and the spring 28 pushes the cable fork 12 to gradually return to the initial position.

[0049] The specific working process of this embodiment is as follows:

[0050] After the stator is placed on the stator clamping and lifting mechanism, the stator is fitted onto the chuck 1. The chuck 1 operates and tightens the stator (the stator lead wire is located at the upper end of the stator). Under the driving action of the first lifting driver 2, the stator clamping and lifting mechanism carries the stator upward. After rising to the through hole of the worktable A, the finger cylinder 23 drives the cable clamp 24 to open. The third cylinder 21 operates, and the piston rod of the third cylinder 21 extends, driving the finger cylinder 23 and the cable clamp 24 to move towards the through hole on the worktable A. Then, the finger cylinder 23 drives the cable clamp 24 to clamp the stator lead wire. Subsequently, the stator clamping and lifting mechanism drives the stator to descend in a straight line. The stator lead wire clamped by the cable clamp 24 is thus straightened by the cable clamp 24. After the stator clamping and lifting mechanism descends to the set position, the finger cylinder 23 drives the cable clamp 24 to open, and the piston rod of the third cylinder 21 retracts, causing the finger cylinder 23 and the cable clamp 24 to return to the initial position. Subsequently, the stator clamping and lifting mechanism raises the stator again, and the piston rod of the drive cylinder 11 retracts, causing the connecting rod 10 to move closer to the center of the through hole on the worktable A. This causes the first test block 4 and the second test block 5 to clamp the stator leads. Because the first test block 4 and the second test block 5 have cutting edges, they pierce the insulation layer on the stator leads. After piercing the insulation layer, the stator leads are tested through the first test block 4 and the second test block 5 and the connected testing equipment. After the test is completed, the drive cylinder 11 drives the first test block 4 and the second test block 5 away from the stator leads.

[0051] Subsequently, the second cylinder 16 drives the second connecting seat 15 to push the moving blade holder 18 along the second slide rail 13 toward the fixed blade holder 20. When the moving blade 17 approaches the fixed blade 19, the wire guide fork 12 just presses the stator lead wire against the side of the moving blade holder 18 and clamps the lead wire. At this time, the moving blade 17 and the fixed blade 19 cut the lead wire under the interaction of forces. During the process of the moving blade holder 18 and the wire guide fork 12 engaging, the wire guide fork 12 is pushed back by pressure, the spring 28 is compressed, and the stator descends with the stator clamping lifting mechanism. After the stator is taken away by the worker or the robot, the cutting system begins to reset. When the moving blade holder 18 separates from the wire guide fork 12, the spring 28 releases the accumulated elastic potential energy, and the spring 28 pushes the wire guide fork 12 to gradually return to the initial position.
