Description

Technical Field

[0001] The invention relates to the technical field of motor stators, and in particular to an automatic device for detecting by piercing an insulating layer of a stator. Background Art

[0002] The motor includes a stator and a rotor. The stator needs to be assembled during the motor assembly process. First, the iron core is wound, and then several iron cores are assembled into a circular stator. The upper surface of the stator has several terminal slots for inserting terminals. Several terminals are inserted into the terminal slots of the stator, and then the two ends of the terminals are bent. After the iron core is wound, there will be some remaining leads on the end face of the stator. In these processes, since the stator leads are constantly bent and rubbed, the enameled wires of the stator may be damaged, resulting in a decrease in the quality of the stator and an increase in the defective rate. Obviously, in the prior art, there is still a lack of detection of the quality of the stator leads. Summary of the invention

[0037] The stator clamping and lifting mechanism includes a chuck 1, a first lifting driver 2, and a fixed block 3. The fixed block 3 is fixed to the lower end of the workbench A. The chuck 1 is directly below the through hole of the workbench A. The area of ​​the through hole on the workbench A is larger than the area of ​​the top of the chuck 1. The third slide rail 3a is fixed on the fixed 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 up or down along the third slide rail 3a. The chuck 1 enters the inner hole of the stator to expand the stator.

[0038] The chuck 1 preferably adopts a multi-claw chuck, such as a three-claw or four-claw pneumatic chuck, and the first lifting driver 2 preferably adopts an electric cylinder. The structure of the multi-claw chuck 1 is generally as follows: it includes a plate cover 1a, a clamping claw 1b, a support handle 1c, and a base 1d.

The expansion or release of the stator is achieved by controlling the expansion or contraction of the clamping claw 1b.

[0039] The lead piercing test mechanism includes a first test block 4, a second test block 5, a first mounting seat 6, a second mounting seat 7, and a first driving system. The first driving system is arranged on a workbench A. The first mounting seat 6 is connected to the first test block 4, and the second mounting seat 7 is connected to the second test block 5. The first test block 4 and the second test block 5 are respectively located at the two ends of the through hole on the workbench A, and cooperate with the first driving system. The first test block 4 and the second test block 5 have cutting edges on the sides for piercing the insulation layer of the stator lead. The first test block 4 and the second test block 5 are both connected with test wires, and the test wires are connected to a test electrical appliance. The test electrical appliance can be, for example, a multimeter. The first test block 4 is connected with a first pressure block 4a, and the second test block 5 is connected with a second pressure block 5a. The first pressure block 4a and the second pressure block 5a are provided with grooves for hiding the test wires.

[0040] The first driving system includes a first slide rail 8, a first slider 9, a connecting rod 10, and a driving cylinder 11. There are two groups of first slide rails 8. Both ends of each group of first slide rails 8 are respectively slidably connected to the first slider 9. The two groups of first slide rails 8 are symmetrically fixed at both ends of the through holes on the workbench A. There are two groups of connecting rods 10. Both ends of each group of connecting rods 10 are respectively connected to a first slider 9, and are vertically related to any first slide rail 8. One connecting rod 10 cooperates with the first detection block 4, and the other connecting rod 10 cooperates with the second detection block 5. Both ends of the driving cylinder 11 are provided with piston rods, and the two connecting rods 10 are respectively connected to the two ends of the driving cylinder 11. When the lead piercing test mechanism is activated, the driving cylinder 11 drives the connecting rods 10 at both ends along the first slide rail 8 to push the first detection block 4 and the second detection block 5 to the middle of the through hole on the workbench A. After reaching the specified position, the stator lead is pierced and detected.

[0041] The post-test lead cutting mechanism comprises a wire management fork 12, a second driving system, and a cutter system. The wire management fork 12 has a groove on its side. The wire management fork 12 cooperates with the cutter system, and the cutter system cooperates with the second driving system.

[0042] The second driving system includes a second slide rail 13, a second slider 14, a second connecting seat 15, and a second cylinder 16. There are two groups of second slide rails 13. The same end of each group of second slide rails 13 is connected to the second slider 14. The two groups of second slide rails 13 are symmetrically fixed at both ends of the through holes on the workbench A and are parallel to the first slide rail 8. The second slider 14 cooperates with the cutter system, and the cutter system cooperates with the second connecting seat 15. It also includes a push plate 16a and a fourth cylinder 16b. The fourth cylinder 16b is fixed on the workbench A, and the fourth cylinder 16b is connected to the push plate 16a. There is a through hole on the push plate 16a. The second cylinder 16 passes through the through hole on 16a and is fixed to the second connecting seat 15.

[0043] The cutting system includes a movable knife 17, a movable knife seat 18, a fixed knife 19, and a fixed knife seat 20. The movable knife 17 is fixed to the movable knife seat 18 and is located on one side of the through hole on the workbench A. The movable knife seat 18 is connected to the second slider 14 and is fixed to the second connecting seat 15. The fixed knife seat 20 is arranged on the workbench A and is located on the other side of the through hole on the workbench A. The fixed knife 19 is fixed to the fixed knife seat 20, and the wire management fork 12 is fixed to the fixed knife seat 20.

[0044] After the lead cutting mechanism is activated, the second cylinder 16 drives the second connecting seat 15 to push the moving knife seat 18 to move 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 just presses the stator lead against the side of the moving knife seat 18 to clamp the lead. At this time, the moving knife 17 and the fixed knife 19 cut the lead under the interaction of force, and the stator is lowered along with the stator clamping lifting mechanism. After the stator is taken away by the staff or the manipulator, the cutting knife system is reset to release the cut lead to prevent the cut lead from falling into the stator winding.

[0045] The present invention also includes a lead wire alignment and wiring arrangement mechanism, which is fixed on the workbench A and cooperates with the stator clamping and lifting mechanism.

[0046] The lead wire alignment and wiring management mechanism includes a third cylinder 21, a fixed seat 22, a finger cylinder 23, and a wire management clamp 24. The fixed seat 22 is fixed to the workbench A by screws or welding. The third cylinder 21 is fixed to the fixed seat 22. The third cylinder 21 is connected to the finger cylinder 23. The finger cylinder 23 is connected to the wire management clamp 24. The finger cylinder 23 and the wire management clamp 24 are located above the driving cylinder 11.

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

[0048] The workbench A also includes a buffer mechanism, which is arranged 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. A through hole is provided on the positioning block 25. One end of the guide rod 27 passes through the through hole on the positioning block 25 and is fitted with a clearance of the through hole. 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 movable knife seat 18 is combined with the cable fork 12, the cable fork 12 retreats under the action of pressure, and the spring 28 is compressed. When the movable knife seat 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] When the stator is placed on the stator clamping and lifting mechanism, the stator is sleeved on the chuck 1, the chuck 1 works and tightens the stator (the stator lead is located at the upper end of the stator), and under the driving action of the first lifting driver 2, the stator clamping and lifting mechanism carries the stator up, and after rising to the through hole of the workbench A, the finger cylinder 23 drives the wire clip 24 to open, and when the third cylinder 21 works, the piston rod of the third cylinder 21 extends, driving the finger cylinder 23 and the wire clip 24 to move toward the through hole on the workbench A, and then, the finger cylinder 23 drives the wire clip 24 to clamp the stator lead, and then, the stator clamping and lifting mechanism drives the stator to descend in a straight line, and the stator lead clamped by the wire clip 24 is straightened by the wire clip 24, and after the stator clamping and lifting mechanism descends to the set position, the finger cylinder 23 drives the wire clip 24 to open, and the piston rod of the third cylinder 21 retracts, so that the finger cylinder 23 and the wire clip 24 return to the initial position. Subsequently, the stator clamping and lifting mechanism again raises the stator, and the piston rod of the driving cylinder 11 retracts to drive the connecting rod 10 to move closer to the middle of the through hole on the workbench A, so that the first test block 4 and the second test block 5 clamp the stator lead. Since the first test block 4 and the second test block 5 have cutting edges, the first test block 4 and the second test block 5 pierce the insulation layer on the stator lead. After piercing the insulation layer, the stator lead is tested by the first test block 4 and the second test block 5 and the connected test equipment. After the test is completed, the driving cylinder 11 drives the first test block 4 and the second test block 5 away from the stator lead.

[0051] Then the second cylinder 16 drives the second connecting seat 15 to push the moving knife seat 18 to move 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 just presses the stator lead against the side of the moving knife seat 18 to clamp the lead. At this time, the moving knife 17 and the fixed knife 19 cut the lead under the interaction of force. During the combination of the moving knife seat 18 and the wire fork 12, the wire fork 12 retreats under the action of pressure, the spring 28 is compressed, and the stator descends along with the stator clamping lifting mechanism. After the stator is taken away by the staff or the manipulator, the cutting knife system starts to reset. When the moving knife seat 18 is separated from the wire fork 12, the spring 28 releases the accumulated elastic potential energy, and the spring 28 pushes the wire fork 12 to gradually return to the initial position.
