Description

Technical Field

[0047] Please refer to Figures 1 to 19 , an embodiment of the present invention discloses a terminal installation machine 100 .

[0048] In one embodiment, if Figure 1-Figure 9As shown, the terminal installation machine 100 includes a frame 10 with a workbench 101, a turntable mechanism 102 rotatably arranged on the workbench 101, a loading and unloading device, a detection device 30, a pre-pressing device 40, a pressing device 50, a wire cutting device 60, a stator performance testing device 70, a marking device 80 and a scanning device which are sequentially arranged on the workbench 101 along the rotation direction of the turntable mechanism 102 and located beside the turntable mechanism 102, and a lifting and lowering placement seat 104 is provided on the turntable mechanism 102, and the placement seat 104 is used to place and fix the stator 900. Among them, the stator 900 includes a stator core 901 and a winding group, the winding group is wound on the stator core 901, and the wire end 903 of the winding group extends out of the stator core 901.

[0049] The frame 10 is used to carry and support the terminal installation machine 100. A workbench 101 for completing various functions is provided on the frame 10. The turntable mechanism 102 includes a first rotating drive member and a turntable 103. The first rotating drive member can be a rotating motor. One end of the first rotating drive member is arranged on the workbench 101, and the output end of the first rotating drive member extends out of the workbench 101 and is arranged on the turntable 103, so that there is a gap between the turntable 103 and the workbench 101. The turntable 103 is provided with second through holes corresponding to the loading and unloading device, the detection device 30, the pre-pressing device 40, the pressing device 50, the wire cutting device 60, the stator performance testing device 70, the marking device 80 and the scanning device. The placement seats 104 are respectively inserted into the second through holes and the placement seats 104 and the second through holes are clearance-matched, so that the placement seats 104 can be pushed out or taken out by external force, so that the placement seats 104 can move up or down relative to the turntable 103 under the action of external force. The placement seats 104 are used to place and fix the stator 900, so that the placement seats 104 can simultaneously drive the stator 900 to move up or down when they move up or down.

[0050] The loading and unloading device includes a conveying structure 201 arranged on the workbench 101, a transport component 202 arranged on the workbench 101 and a placement seat 104 located at the initial position of the turntable 103. The terminal installation machine 100 also includes a good product unloading channel 203 and a defective product unloading channel 204. The transport component 202 is located at the rear end of the conveying structure 201, and the transport component 202 is vertically arranged with the output material structure. The good product unloading channel 203 and the defective product unloading channel 204 are respectively located on both sides of one end of the output material structure facing the transport component 202, and the good product unloading channel 203 is located between the turntable mechanism 102 and the defective product channel.

[0051] During the loading process, the stator 900 with the winding wires is first placed on the conveying seat on the conveying material structure 201 through a robot (external equipment). The conveying structure transports the conveying seat with the stator 900 with the winding wires from its initial position to the tail end of the conveying material structure 201, so that the clamp of the conveying component 202 can grab the stator 900 and transport the stator 900 to the placement seat 104 located at the initial position of the turntable 103 to complete the loading.

[0052] During the unloading process, after loading, the stator 900 with the winding wire is driven to the next work by rotating the turntable 103, until the stator 900 completes all the processing steps, and then the stator 900 returns to the initial position of the turntable 103, and then the stator 900 is grabbed by the clamp of the conveying component 202 and conveyed to the good product unloading channel 203 or the defective product unloading channel 204, wherein the defective product unloading channel 204 includes a press-fit defective product channel and a performance defective product channel, so that the subsequent staff can directly put the stator 900 into the corresponding storage box, avoid manual classification, save time and labor, and improve work efficiency. At the same time, a rework input port 205 is also provided on the workbench 101. After the staff reworks the defective product, the reworked stator 900 is placed in the rework input port 205, and then the reworked stator 900 is placed on the placement seat 104 located at the initial position of the turntable 103 through the conveying component 202, so as to improve the utilization rate of defective products.

[0053] The detection device 30 is used to detect whether the position of the thread end 903 meets the requirements. The detection device 30 includes a third support frame 301 and a shooting structure 302. One end of the third support frame 301 is set on the workbench 101, and the shooting structure 302 is set on the other end of the third support frame 301 and is located above the turntable 103. By rotating the turntable 103, the stator 900 is rotated from the initial position of the turntable 103 to just below the shooting structure 302. The shooting structure 302 is located on the stator on the placement seat 104. The stator 900 is photographed and the photographed image is then uploaded to the host computer for image processing. The host computer determines whether the wire end 903 is located in the terminal mounting groove of the stator core 901 according to a preset program. Since the wire end 903 is located in the terminal mounting groove after the stator 900 is wound, the wire end 903 can be pressed tightly when the terminal 902 is subsequently inserted into the terminal mounting groove. Therefore, before inserting the terminal 902, it is necessary to first check whether the position of the wire end 903 meets the requirements to avoid increasing the defective rate of the stator 900.

[0054] Specifically, the shooting structure 302 is a CCD camera.

[0055] The pre-pressing device 40 is used to pre-press the terminal 902. The pre-pressing device 40 includes a first lifting and rotating structure 401 and a clamping and pre-pressing structure 402. The first lifting and rotating structure 401 is arranged on the workbench 101 and is located in the gap between the workbench 101 and the turntable 103. By rotating the turntable 103, the stator 900 that has completed the position detection of the wire head 903 is rotated to the top of the first lifting and rotating structure 401. The first lifting and rotating structure 401 is placed by the lifting and placing seat 104 thereby lifts the stator 900 placed in the placement seat 104 to a preset distance, so that the clamping pre-pressing structure 402 can pre-press the terminal 902 into the terminal installation groove of the stator core 901. The clamping pre-pressing structure 402 is arranged on the workbench 101, located on the side of the turntable 103, and located above the turntable 103, so that the structural design of the pre-pressing device 40 is compact, so that the first lifting and rotating structure 401 and the clamping pre-pressing structure 402 can cooperate to complete the pre-pressing of the terminal 902.

[0056] During the pre-stressing process, the clamping pre-stressing structure 402 clamps the single terminal 902 in a horizontal state and rotates it to make the single terminal 902 in a vertical state, then moves the single terminal 902 in the vertical state to the positive direction of the terminal mounting slot, and then presses down to press the terminal 902 into the terminal mounting slot by a preset distance, thereby completing the pre-stressing of the terminal 902.

[0057] The press-fitting device 50 is used to tighten and press-fit the pre-stressed terminal 902, that is, to press the pre-stressed terminal 902 into the terminal installation groove. The press-fitting device 50 includes a second lifting and rotating structure 501 and a press-fitting structure 502. The second lifting and rotating structure 501 is arranged on the workbench 101 and is located in the gap between the workbench 101 and the turntable 103. By rotating the turntable 103, the stator 900 that has completed the pre-stressing of the terminal 902 is rotated to the top of the second lifting and rotating structure 501. The second lifting and rotating structure 501 lifts the placement seat 104 to lift the stator 900 that has completed the pre-stressing of the terminal 902 placed in the placement seat 104 to a preset distance, so as to facilitate the press-fitting structure 50 The pre-stressed terminal 902 is tightened and pressed. The pressing structure 502 is arranged on the workbench 101, beside the turntable 103, and above the turntable 103, that is, the turntable 103 is located between the pressing structure 502 and the second lifting and rotating structure 501, so that the second lifting and rotating structure lifts the placement seat 104 and lifts the stator 900 with the pre-stressed terminal 902 placed in the placement seat 104 to a preset distance, so that the pressing structure 502 descends to press the pre-stressed terminal 902 into place, and the terminal 902 is tightened and pressed. The second lifting and rotating structure 501 and the pressing structure 502 cooperate with each other to complete the tightening and pressing of the terminal 902.

[0058] The wire cutting device 60 is used to cut the wire ends 903. The wire cutting device 60 includes a third lifting and rotating structure 601 and a wire cutting structure 602. The third lifting and rotating structure 601 is arranged on the workbench 101 and is located in the gap between the workbench 101 and the turntable 103. By rotating the turntable 103, the stator 900 with the terminal 902 pressed is rotated to the top of the third lifting and rotating structure 601. The third lifting and rotating structure 601 lifts the placement seat 104 to lift the stator 900 with the terminal 902 pressed and placed in the placement seat 104 to a preset distance, so that the wire cutting structure 602 can cut the wire ends 903. The wire cutting structure 602 can be slidably arranged on the workbench 101, so that the wire cutting structure 602 can be moved to a suitable position to cut the wire ends 903.

[0059] The stator performance testing device 70 is used to perform performance testing on the stator 900. By rotating the turntable 103, the stator 900 with the wire ends 903 cut off is rotated to the corresponding position of the stator performance testing device 70, so as to facilitate performance testing of the stator with the wire ends 903 cut off, wherein the performance test is one or more of an electrical strength test, a DC resistance test, a turn-to-turn insulation test, and an inductance test.

[0060] The marking device 80 includes a laser marking machine, a smoke purifier and a fourth lifting and rotating structure. The laser marking machine and the smoke purifier are both arranged on the workbench 101 and located on the side of the turntable 103. The fourth lifting and rotating structure is arranged in the gap between the turntable 103 and the workbench 101. By rotating the turntable 103, the stator 900 that has completed the performance test is rotated to the position corresponding to the laser marking machine and is located directly above the fourth lifting and rotating structure. Before marking, the fourth lifting and rotating structure lifts the placement seat 104 and the stator 900 to a preset distance, so that the laser marking machine can mark the stator 900 that has completed the performance test, so that the stator 900 has a recognizable QR code or bar code. At the same time, the smoke purifier purifies the smoke generated by marking, which is beneficial to environmental protection. After marking is completed, the fourth lifting and rotating structure drives the placement seat 104 and the stator 900 to reset.

[0061] Among them, the first lifting and rotating structure 401, the second lifting and rotating structure 501, the third lifting and rotating structure 601 and the fourth lifting and rotating structure are the same structure.

By rotating the turntable 103, the marked stator 900 is rotated to the corresponding position of the scanning device, so as to scan the stator 900 and identify its information. The scanning device is a barcode scanner. After the scanning is completed, the turntable 103 is rotated again to rotate the scanned stator 900 to the initial position of the turntable 103, and then the scanned stator 900 is transported to the good product unloading channel 203 or the defective product unloading channel 204 through the transport component 202.

The two guide rods 410 are both arranged on the first lifting drive member 408 and are respectively located on both sides of the connecting shaft 409. The first fixed seat 407 is arranged on one end of the connecting shaft 409, and the surface of the first fixed seat 407 away from the connecting shaft 409 is flush with the end faces of the two guide rods 410, so that the two guide rods 410 and the first fixed seat 407 cooperate with each other to fix the placement seat 104, thereby realizing that the first lifting component 406 can lift the placement seat 104.

[0066] Since a stator 900 needs to pre-press multiple terminals 902, after pre-pressing one terminal 902, the stator 900 needs to be rotated by a certain angle so that the next terminal installation slot corresponds to the terminal 902 to be pre-pressed. The present application drives the stator 900 to rotate while driving the placement seat 104 to rotate by setting a rotating component 405. The rotating component 405 includes a second rotating driving member 415, a synchronous belt 413 and a synchronous wheel 414. The synchronous wheel 414 is sleeved on one end of the connecting shaft 409. The two ends of the synchronous belt 413 are respectively meshed and connected with the output ends of the synchronous wheel 414 and the second rotating driving member 415, so that The second rotating drive member 415 drives the synchronous wheel 414 to rotate through the synchronous belt 413. The synchronous wheel 414 rotates and drives the connecting shaft 409 to rotate, thereby driving the first fixed seat 407 set on the connecting shaft 409 to rotate. After being lifted, the first fixed seat 407 will contact the placement seat 104 to fix the placement seat 104. Therefore, as the first fixed seat 407 is continuously lifted, the placement seat 104 is also lifted. At the same time, the rotation of the first fixed seat 407 drives the placement seat 104 to rotate, realizing the rotation of the stator 900. By rotating the stator 900, the pre-pressing of multiple terminals 902 can be completed, thereby improving work efficiency. Exemplarily, the pre-pressed terminals 902 can be 1, 2, 3, 4, 5, 6, etc. This embodiment does not limit the number of pre-pressed terminals 902, and pre-pressing can be performed according to actual conditions. Specifically, the second rotating drive member 415 is a rotating motor.

[0067] The terminal installation machine 100 also includes a terminal loading device 82 and a punching device 83. The terminal 902 is loaded in the form of a coil and is loaded through the loading device. Therefore, the punching device 83 is required to punch the coiled terminal 902 into a single terminal 902 for subsequent installation. The punched single terminal 902 is placed horizontally, and the insertion direction of the terminal installation slot of the stator 900 is perpendicular to the horizontally placed terminal 902. Therefore, the clamping pre-pressing structure 402 needs to rotate the horizontal terminal 902 into a vertical state after clamping the flatly placed terminal 902, so that the insertion end of the terminal 902 is consistent with the insertion direction of the terminal installation slot.

[0068] like Figure 6 As shown, Figure 6 Figures a to b show that the clamping and pre-stressing structure 402 clamps a single terminal 902 in a horizontal state and rotates it to make the single terminal 902 in a vertical state. The clamping and pre-stressing structure 402 includes a first support frame 403 and a clamping and rotating component 404. One end of the first support frame 403 is set on the workbench 101. The clamping and rotating component 404 can be slidably set on the first support frame 403, so that the clamping and rotating component 404 can slide to the terminal 902 and clamp the terminal 902, and then pre-insert the terminal 902 into the terminal installation groove. The clamping and rotating component 404 is used to clamp the terminal 902 and rotate the terminal 902 to a vertical state and then insert it into the terminal installation groove of the stator core 901.

[0069] Specifically, the clamping pre-pressing structure 402 also includes a first clamping component 411 and a third rotating driving component 412. One end of the third rotating driving component 412 can be slidably arranged on the slide rail of the first support frame 403 through a slider, so that the third rotating driving component 412 can slide on the first support frame 403. The third rotating driving component 412 can be a pneumatic swing table swing cylinder, which is a pneumatic actuator that uses compressed air to drive the output shaft to perform reciprocating rotation within a certain angle range. One end of the first clamping component 411 is arranged on the output end of the third rotating driving component 412, so that the third rotating driving component 412 can drive the first clamping component 411 to rotate, thereby realizing the rotation of the terminal 902 in a horizontal state to the terminal 902 in a vertical state. The power source for the opening or closing action of the first clamping component 411 is gas.

[0070] In one embodiment, if Figure 7-Figure 9As shown, the press-fitting structure 502 includes a second support frame 503, a pressing head assembly 504 and a wire pulling assembly 505. One end of the second support frame 503 is arranged on the workbench 101, and the pressing head assembly 504 is arranged at the other end of the second support frame 503, and the pressing head assembly 504 is located directly above the placement seat 104, so that the pressing head assembly 504 can tighten and press the pre-pressed terminal 902. The wire pulling assembly 505 is arranged on the second support frame 503, and the wire pulling assembly 505 is used to clamp the wire end 903 of the stator 900 to avoid bringing the wire end 903 into the stator core 901 during tightening and pressing.

[0071] Specifically, the pressure head assembly 504 includes a first pressure head 509 and a lifting motor 510 for driving the first pressure head 509 to move upward or downward. The lifting motor 510 is arranged on the second support frame 503. The first pressure head 509 is arranged on the output end of the lifting motor 510. The first pressure head 509 is arranged toward the stator 900. The lifting motor 510 drives the first pressure head 509 to move downward until the first pressure head 509 is pressed tightly against the terminal 902, and then continues to move downward to a preset distance, so as to fasten the terminal 902 in the terminal installation groove and complete the press-fitting of the terminal 902. In addition, a pressure sensor and a displacement sensor are arranged in the first pressure head 509. The pressure sensor is used to sense the pressure of the press-fit terminal 902, and the displacement sensor is used to measure the distance of the terminal 902 being pressed downward.

[0072] The press-fitting structure 502 also includes a connecting plate 506, a first slide 507 and a pressing plate 508. One end of the connecting plate 506 is arranged on the second support frame 503. The connecting plate 506 is provided with a slide rail compatible with the first slide 507. The first slide 507 can be slidably arranged on the slide rail so that the first slide 507 can move up or down along the slide rail. The pressing plate 508 is arranged on the first slide 507. The pressing plate 508 is used to press the stator core 901 to prevent the stator core 901 from being displaced during the press-fitting process of the terminal 902.

[0073] The wire pulling assembly 505 is a clamp that can be pneumatically driven to open or close. Before the terminal 902 is pressed, the clamp first clamps the wire end 903, and then the terminal 902 is tightened and pressed, which can avoid the wire end 903 being brought into the stator core 901 when the terminal 902 is pressed.

[0074] In one embodiment, if Figure 10-Figure 14 As shown, the wire cutting structure 602 is used to cut the wire ends 903 of the stator core 901, and the wire cutting structure 602 includes a second fixing seat 603, a first fixing member 604, a wire clamping assembly 605 and a cutting assembly 606.

[0075] The second fixed seat 603 includes a fixed plate 610 and a second slide 611, the second slide 611 can be slidably arranged on the fixed plate 610, and the first fixed member 604 can be slidably arranged on the second slide 611, so that the second slide 611 slides toward the direction of the stator core 901 and drives the first fixed member 604 to slide toward the direction of the stator core 901, so that the first fixed member 604 can be clamped on the side wall of the stator core 901, and the clamping assembly 605 for clamping the wire head 903 is arranged on the first fixed member 604, so that the first fixed member 604 moves toward the direction of the stator core 901 and drives the clamping assembly 605 to move toward the direction of the stator core 901, so that the first fixed member 604 can be clamped on the side wall of the stator core 901. After the fixed piece 604 is clamped on the side wall of the stator core 901, the wire clamping assembly 605 can clamp the wire end 903. The shearing assembly 606 is arranged on the second slide 611 and is located directly above the wire clamping assembly 605, and is used to shear the wire end 903. Since the first fixed piece 604 is clamped on the side wall of the stator core 901, the wire clamping assembly 605 can straighten the entire wire end 903 when clamping the wire end 903, thereby avoiding the stator core 901 from shifting when the wire clamping assembly 605 clamps the wire end 903 and straightens the wire end 903, resulting in the wire end 903 not being straightened, that is, being in a bent state, thereby resulting in the length of the short wire end 903 after shearing by the shearing assembly 606 being non-uniform, and further resulting in unstable shearing accuracy.

[0076] Specifically, the shearing component 606 may be a gas shear.

[0077] In one embodiment, the wire cutting structure 602 further includes a second fixed structure 607, which is retractably arranged on the machine platform, and is pressed against the stator core 901 and located directly above the stator core 901, for positioning and fixing the stator core 901. In the working state, the second lifting and rotating structure 501 lifts the stator core 901 to the shearing opening of the wire cutting structure 602, and then the second fixed structure 607 descends and presses against the side surface of the stator core 901 away from the second lifting and rotating structure 501, so that the second fixed structure 607 and the second lifting and rotating structure 501 fix the stator core 901 in the vertical direction, further improving the stability of the stator core 901 fixation, that is, when the clamping structure pulls the wire head 903 with force, the wire head 903 cannot pull the stator core 901, thereby further improving the uniformity of the length of the short wire head 903 after the wire cutting structure 602 cuts, and improving the precision of the precision cutting.

[0078] Furthermore, the second fixed structure 607 includes a fixed rod 612, a second lifting drive member 613 and a second pressing head 614. The second lifting drive member 613 can be a cylinder. One end of the fixed rod 612 is fixed to the machine platform, and the fixed plate 610 is fixed to the fixed rod 612. The second lifting drive member 613 is arranged at the other end of the fixed rod 612. The second pressing head 614 is arranged at the output end of the second lifting drive member 613, so that the second lifting drive member 613 can drive the second pressing head 614 to move upward or downward, so that when the second pressing head 614 is in the working state, 4 can be lowered onto the stator core 901 and press the stator core 901. The second pressing head 614 is a pure plane downward pressing positioning, which not only prevents the stator core 901 from floating or the stator core 901 from tilting during the jacking, but also forms a vertical fixation for the stator core 901 with the second jacking rotating structure 501, further improving the fixation of the stator core 901, and preventing the clamping assembly 605 from pulling the stator core 901 out of position when pulling the straight wire head 903, thereby further improving the uniformity of the length of the short wire head 903 cut by the wire cutting structure 602 and improving the precision of the precision cutting.

[0079] In one embodiment, a fixing opening 608 is provided on the front end surface of the first fixing member 604. When in working state, the second slide 611 slides toward the direction of the stator core 901 and drives the first fixing member 604 to slide toward the direction of the stator core 901 until the side wall of the stator core 901 is stuck in the fixing opening 608 to be fixed. The fixing opening 608 is in surface contact with the side wall of the stator core 901, which increases the force bearing area and thus improves the stability of fixing the stator core 901, and prevents the clamping assembly 605 from pulling the stator core 901 at the same time during the process of straightening the straight head 903, so that The wire end 903 is in a bent state, resulting in the short wire end 903 being of non-uniform length and low precision after being cut by the shearing assembly 606. The wire clamping assembly 605 includes a clamping claw driving member arranged on the first fixing member 604, and two clamping claws arranged on the output end of the clamping claw driving member. The two clamps form a clamping opening for clamping the wire end 903. The distance between the clamping opening and the side wall of the stator core 901 is greater than the distance between the fixing opening 608 and the side wall of the stator core 901, so that when the side wall of the stator core 901 is stuck in the fixing opening 608, the clamping opening is close to the wire end 903, which is convenient for clamping the wire end 903.

[0080] Furthermore, the first fixing member 604 is a plate-like structure, and the fixing opening 608 is arranged on the front end surface of the plate-like structure, and the fixing opening 608 is an arc-shaped opening that is compatible with the curvature of the side wall of the stator core 901. The side wall of the stator core 901 is inserted into the first arc-shaped opening to form a fixation. The first fixing member 604 is a plate-like structure, and an arc-shaped opening is provided on the front end surface of the plate-like structure, and the stator core 901 can be horizontally fixed, so that the wire cutting structure 602 has a compact structural design, a simple structure, a small size, and high working efficiency.

[0081] Specifically, the material of the first fixing member 604 is an elastic material, so that the first fixing member 604 can fix the stator core 901 without scratching the stator core 901 .

[0082] In one embodiment, if Figure 15-19 As shown, the stator performance test device 70 includes a workbench 101, a positioning structure 702, a lifting structure 702 and a test clamping assembly 703. The performance of the stator 900 is tested through the terminal 902, and the performance test of the stator 900 is one or more of an electrical strength test, a DC resistance test, a turn-to-turn insulation test, and an inductance test, all of which are electrical performance tests. Therefore, when the performance test of the stator 900 is performed, insulation is required. A first through hole 105 is provided at the bottom of the placement seat 104. The first through hole 105 is used for the lifting structure 702 to extend into or out of the placement seat 104, so that the lifting structure 702 can lift the stator 900. The material of the placement seat 104 is metal, which is easy to conduct electricity. Therefore, only the stator 900 is lifted during lifting.

[0083] The positioning structure 701 is used to position the stator 900 , and the positioning structure 701 can be telescopically disposed on the workbench 101 .

[0084] The lifting structure 702 is used to lift the stator 900 to a predetermined height position. The lifting structure 702 includes a second lifting component 704 and a positioning fixture 705. One end of the second lifting component 704 is arranged on the workbench 101. The positioning fixture 705 is arranged on the output end of the second lifting component 704, so that the second lifting component 704 can drive the positioning fixture 705 to move upward or downward, and the placement seat 104 is located between the positioning structure 701 and the positioning fixture 705, so that the stator 900 can be positioned and pressed after the stator 900 is lifted, and the diameter of the first through hole 105 is larger than the diameter of the stator 900. The diameter of the positioning fixture 705 is smaller than the diameter of the stator 900, so that the positioning fixture 705 can extend or extend into the first through hole 105, and the stator 900 can be placed on the placement seat 104 without falling, so that the second lifting component 704 can drive the positioning fixture 705 to extend into the first through hole 105 and insert it into the stator core 901 of the stator 900 placed in the placement seat 104 to form a fixation, thereby lifting the stator 900 to a predetermined height alone, avoiding lifting the placement seat 104 together, resulting in failure to insulate the stator 900, resulting in inaccurate test results or causing a short circuit. The material of the positioning fixture 705 is an insulating material.

[0085] The test clamping assembly 703 is arranged on the positioning structure 701 and is located on one side of the positioning structure 701, so that when the positioning structure 701 descends, it drives the test clamping assembly 703 to descend to the stator 900, so that the test clamping assembly 703 can clamp the terminal 902 to test the performance of the stator 900. Automated testing is achieved, and test efficiency, comprehensive test rate, and test accuracy are improved.

[0086] In one embodiment, the stator core 901 is inserted with at least four terminals 902, and the test clamping assembly 703 includes at least four test pieces 706, each of which is disposed on the positioning structure 701, and each of which clamps each terminal 902 for performance testing. In this embodiment, the number of terminals 902 and test pieces 706 is not specifically limited, and the number of terminals 902 and test pieces 706 can be 1, 2, 3, 4, 5, 6, 7, or the like.

[0087] Specifically, the test piece 706 includes a first driving piece 707 and a test clamp 708. The first driving piece 707 is arranged on the positioning structure 701, so that the positioning structure 701 drives the first driving piece 707 to descend while performing a descending motion. The test clamp 708 is arranged at the output end of the first driving piece 707, so that the first driving piece 707 can drive the test clamp 708 to clamp the terminal 902 for performance testing, or release the terminal 902 after the performance test is completed. The first driving piece 707 can be a cylinder.

[0088] In one embodiment, the stator performance testing device 70 also includes a grounding component 709, and the grounding component 709 includes a second driving member 710 and a grounding contact 711. The second driving member 710 is arranged on the positioning structure 701, so that when the positioning structure 701 descends, the grounding component 709 is also driven to descend, so that the grounding component 709 can be grounded to the stator 900. The grounding contact 711 is arranged on the output end of the second driving member 710. When the positioning structure 701 descends, the grounding component 709 is also descended to the vicinity of the stator 900, and then the second driving member 710 drives the grounding contact 711 to contact the stator core 901 to achieve a grounding connection, so as to reduce the harm of current to equipment and personnel. Grounding can effectively prevent electric shock accidents and protect personal safety. The test structure and the grounding assembly 709 are simultaneously arranged on the positioning structure 701, so that the positioning structure 701 can drive the test structure and the grounding assembly 709 to descend to the vicinity of the stator 900 while performing a descending movement. There is no need for one structure to correspond to one driving component, so that the structural design of the stator performance test device 70 is compact, simple in structure, and high in working efficiency.

[0089] In one embodiment, the positioning fixing member 705 is a positioning shaft, one end of which is arranged on the output end of the second lifting component 704, and the other end of the positioning shaft is inserted into the through hole of the stator core 901 to form a fixation, so that the lifting structure 702 can lift the stator 900 alone to achieve insulation of the stator 900.
