Abstract
Description
Technical Field

[0002] After the rotor is manufactured, it needs to be tested for insulation, resistance, etc. The testing of electronic rotor plays a key role in ensuring the performance, safety and reliability of motor.
[0003] Currently, a testing device is used to test the rotor. The testing device includes a support frame and a connector. A spring needle is installed inside the connector. The spring needle abuts against the surface of the commutator segments on the rotor. Before inserting the connector, the rotor on the support frame needs to be rotated to ensure that the commutator segments and the spring needle are in the correct positions after insertion. A shift fork is installed on the support frame to insert into the slot of the iron core after the iron core has rotated to a preset position to stop the iron core from rotating. However, the contact between the shift fork and the iron core can easily damage the surface of the iron core and the enameled wire, affecting the test results. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the implementation of this utility model will be described in detail below with reference to the specific accompanying drawings.
[0026] For ease of description, the terms "front," "rear," "left," "right," "up," and "down" used below are consistent with the front, rear, left, right, up, and down directions of the accompanying drawings, but do not limit the structure of this utility model.
[0027] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms “first,” “second,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a” and similar terms do not indicate a limitation of quantity, but rather indicate the presence of at least one.
[0028] like Figures 1 to 3 As shown, the rotor testing device 100 provided in this embodiment includes a base plate 10 and at least one clamping device 20 and at least one test connection device 30 supported on the base plate 10; the at least one clamping device 20 includes a base 21, a chuck 22 for clamping the iron core 601 of the rotor 600 and rotatably mounted on the base 21, and a rotary drive mechanism 23 for rotating the chuck 22; the at least one test connection device 30 includes a test connector 31 for connecting an electrical performance testing device (not shown), the test connector 31 has a test cavity 311 for moving the commutator of the rotor 600 into and out, and a probe (not shown) for abutting against the side of the commutator 602 is provided in the test connector 31; a position detection device 40 is provided on the base 21 for detecting the rotational position of the iron core 601.
[0029] The aforementioned rotor testing device 100 includes a base plate 10, a clamping device 20, and a testing connection device 30. The clamping device 20 includes a base 21, a chuck 22, and a rotary drive mechanism 23 for rotating the chuck 22. The testing connection device 30 includes a testing connector 31, which has a probe that abuts against the side of the commutator 602. The base 21 is equipped with a position detection device 40 for detecting the rotational position of the core 601. Thus, when the rotary drive mechanism 23 rotates the chuck 22 and the rotor 600, the position detection device 40 detects the rotational position of the core 601. After the position detection device 40 detects that the core 601 has rotated to a preset rotational position, it controls the rotary drive mechanism 23 to stop the rotation of the chuck 22. This avoids damage to the core 601 due to contact with it and ensures the testing effect.
[0030] See Figures 1 to 3The rotor testing device 100 provided in this embodiment includes a base plate 10, a clamping device 20 and a testing connection device 30. The clamping device 20 and the testing connection device 30 are supported on the base plate 10. In this embodiment, the surface of the base plate 10 has a first direction D1 (the direction D1 shown in the figure, hereinafter referred to as the first direction D1) and a second direction D2 (the direction D2 shown in the figure, hereinafter referred to as the second direction D2) that are perpendicular to each other.
[0031] See Figures 1 to 3 The clamping device 20 provided in this embodiment is used to clamp the iron core 601 of the rotor 600. The clamping device 20 includes a base 21, a chuck 22 for clamping the iron core 601 and rotatably mounted on the base 21, and a rotary drive mechanism 23 for rotating the chuck 22. In this embodiment, the number of clamping devices 20 is not limited to two. The two clamping devices 20 are arranged side by side and spaced apart in the first direction D1. The chuck 22 includes a chuck body 221 and jaws 222 disposed on the chuck body 221. The chuck body 221 is rotatably mounted on the base 21 around its center. The number of jaws 222 on the chuck body 221 is not limited to three. The three jaws 222 are arranged at equal angular intervals on the chuck body 221 and are located at the center of the chuck body 221. Driven by the rotation mechanism 23, the rotor 600 can move towards or away from the center of the chuck 22. The rotation drive mechanism 23 is, but is not limited to, a motor belt drive mechanism. It is supported on the base 21 and connected to the chuck 22. The base 21 is equipped with a position detection device 40 for detecting the rotational position of the iron core 601. Thus, the rotor 600 is placed at the center of the chuck 22, so that the rotation axis of the rotor 600 is concentric with the chuck 22. The chuck body 221 drives the jaws 222 to move towards the center to clamp the rotor 600. The rotation drive mechanism 23 drives the chuck 22 and the rotor 600 to rotate. At the same time, the position detection device 40 detects the rotational position of the iron core 601. After the position detection device 40 detects that the iron core 601 has rotated to the preset rotational position, it controls the rotation drive mechanism 23 to stop the rotation of the chuck 22.
[0032] See Figures 1 to 3The position detection device 40 provided in this embodiment includes a proximity sensor 41. The proximity sensor 41 is fixed on the base 21 by a mounting rod 42. The proximity sensor 41 is located at one end of the chuck 22 near the test connector 31 and aligned with the center of the chuck 22. In this embodiment, the proximity sensor 41 is located directly above the rotor 600 and directly opposite the axis of the rotor 600. The proximity sensor 41 is communicatively connected to a PLC (Programmable Logic Controller) system (not shown). It should be noted that after the rotor 600 is placed in, the proximity sensor 41 will detect the presence of the surface of the iron core 601. When the rotor 600 and the iron core 601 rotate, after the slot of the iron core 601 rotates to the position below the proximity sensor 41, the proximity sensor 41 fails to detect the surface of the iron core 601 and outputs a detection signal to the PLC system. The PLC system then controls the rotary drive mechanism 23 to stop rotating. The PLC system is any existing PLC control system that can achieve the above functions.
[0033] See Figure 1 and Figure 2 The test connection device 30 provided in this embodiment includes a test connector 31 for connecting electrical performance testing equipment (not shown). The test connector 31 has a test cavity 311 for the commutator 602 of the rotor 600 to move in and out. The test connector 31 is provided with a probe (not shown) for abutting against the side of the commutator 602. In this embodiment, the electrical performance testing equipment includes, but is not limited to, an insulation withstand voltage tester and a resistance tester. The number of test connection devices 30 is, but not limited to, two. The two test connection devices 30 are arranged side by side and spaced apart in the first direction D1, and are connected to two... Each clamping device 20 is aligned and arranged in a corresponding manner. The test connector 31 of each test connection device 30 is movably mounted on the base plate 10 along the second direction D2. Each test connection device 30 also includes a longitudinal power member 32 for driving the test connector 31 to move along the second direction D2. The longitudinal power member 32 is, but is not limited to, a cylinder. Thus, under the drive of the longitudinal power member 32, the test connector 31 moves along the second direction D2 relative to the chuck 22 of its corresponding clamping device 20, so that the commutator 602 of the rotor 600 slides into the test cavity 311 of the test connector 31.
[0034] Please continue reading Figure 1 and Figure 2In this embodiment, a loading / unloading hole 11 is provided in the middle of the substrate 10. The base 21 of each clamping device 20 is movably mounted on the substrate 10 along the first direction D1. Each clamping device 20 also includes a transverse power member 24 for driving the base 21 to move along the first direction D1. The transverse power member 24 is, but is not limited to, a cylinder. In this way, the transverse power member 24 can drive the base 21 to reciprocate between the loading / unloading hole 11 and the corresponding test connection device 30. That is, after the clamping device 20 clamps the rotor 600 to be tested in the loading / unloading hole 11, it moves to the position corresponding to the test connection device 30, and after testing, it moves to the loading / unloading hole 11 for unloading. The two clamping devices 20 alternately perform loading / unloading and testing, which can improve work efficiency and reduce production costs.
[0035] See Figures 1 to 3 In this embodiment, the jaw 222 is provided with an insulating clamping member 223 for abutting against the side of the iron core 601. In this embodiment, the insulating clamping member 223 is made of insulating materials such as polyaryletherketone and polyetherketone, and is fixedly installed on the jaw 222 by fasteners such as screws and bolts. In this way, the rotor 600 is clamped by the insulating clamping member 223, which can ensure the accuracy of electrical detection and avoid measurement errors caused by current leakage.
[0036] See Figure 1 and Figure 2 In this embodiment, an insulating support base 50 for supporting the iron core 601 is provided on the substrate 10. The insulating support base 50 is movably mounted on the substrate 10 and has a support groove that matches the shape of the iron core 601. It should be noted that when the test connector 31 of the test connection device 30 is connected to the commutator 602, the rotor 600 can be held by the insulating clamping member 223 of the chuck 22 or supported on the insulating support base 50. Of course, when the insulating clamping member 223 is not installed on the chuck 22, the insulating support base 50 can be provided to support the rotor 600 during the test.
[0037] See Figure 1 and Figure 2 In this embodiment, the insulating support base 50 is provided with a limiting protrusion 51 for insertion into the groove of the iron core 601, so that the iron core 601 can be limited in the circumferential direction.
[0038] See Figure 2In this embodiment, the probe is telescopically and movably installed in the test connector 31. A pinhole 312 for probe movement is formed on the inner wall of the test cavity 311. The test connector 31 is provided with a driving component (not shown) for driving the end of the probe to extend into the test cavity 311. The driving component is, but is not limited to, an air bladder. Thus, after the commutator 602 moves into the test cavity 311, the air bladder inflates and pushes the probe out of the pinhole 312 in the test cavity 311 to contact the surface of the commutator 602.
[0039] See Figure 4 and Figure 5 The testing equipment 1000 provided in this embodiment includes a frame 1001 and the rotor testing device 100 described above. The frame 1001 is provided with a recovery device 200 and a transfer device 300. The recovery device 200 includes a recovery belt 201 rotatably supported on the frame 1001, a support seat 202 disposed on the recovery belt 201 for placing the rotor 600, and a recovery power component 203 for driving the recovery belt 201 to rotate. The transfer device 300 includes a clamping assembly 301 for clamping the rotor 600 and reciprocating between the rotor testing device 100 and the recovery device 200. In this embodiment, a conveyor line 500 is provided on one side of the frame 1001 for conveying the rotor 600 along the first direction D1. A first loading / unloading assembly 501 is provided below the conveyor line 500. The first loading / unloading assembly 501 is vertically mounted below the conveyor line 500. The first loading / unloading assembly 501 can lift the rotor 600 on the conveyor line 500 through the loading / unloading holes 11 of the substrate 10 to above the substrate 10, and lower the rotor 600 back onto the conveyor line 500 after testing. A recycling device 200 is provided on one side of the rotor testing device 100. The recycling device 200 includes a recycling belt 201, a support seat 202, and... The power unit 203 is a recyclable component, which is not limited to a motor. Multiple support seats 202 are provided on the recycling belt 201. The multiple support seats 202 are arranged sequentially along the length direction of the recycling belt 201. The clamping component 301 of the transfer device 300 can move along the first direction D1. In this way, when the rotor 600 measured by the rotor testing device 100 fails to meet the standard, the rotor 600 is clamped onto the recycling device 200 by the clamping component 301 of the transfer device 300 and placed into the support seat 202 for removal. If the rotor 600 meets the standard, the first loading and unloading component 501 sends the rotor 600 to the conveyor line 500.
[0040] See Figure 4 and Figure 5In this embodiment, a marking device 400 is provided on the frame 1001. The marking device 400 includes a platform 401 for placing the rotor 600 and a marking machine 402 for marking the rotor 600 on the platform 401. In this embodiment, a second loading / unloading assembly 502 is provided below the conveyor line 500. The structure of the second loading / unloading assembly 502 is basically the same as that of the first loading / unloading assembly 501. The second loading / unloading assembly 502 is movably installed below the conveyor line 500. The marking device 400 includes a platform 401, a marking machine 402, a clamping assembly 403 that can reciprocate between the platform 401 and the second loading / unloading assembly 502, and a material-shifting assembly 407. The second loading / unloading assembly 502 can lift the rotor 600 on the conveyor line 500. The clamping assembly 403 includes a clamping manipulator 404 for clamping the rotor 600, a clamping lifting cylinder 405 for lifting the clamping manipulator 404, and a rotary cylinder 406 for rotating the clamping lifting cylinder 405 horizontally. The material-shifting assembly 407 includes a material-shifting assembly for engaging the rotor 600. The second loading / unloading assembly 502 raises the rotor 600 on the conveyor line 500, and the clamping robot 404 clamps the rotor 600. The rotary cylinder 406 rotates the clamping robot 404 horizontally half a turn, and the clamping lifting cylinder 405 controls the clamping robot 404 to descend and place the rotor 600 on the platform 401. The clamping cylinder 409 can control the clamping rod 408 to extend and touch the surface of the iron core 601 to ensure that the iron core 601 falls into the platform 401 as a whole. Then, the marking machine 402 controls the marking machine to perform laser marking on the surface of the iron core 601. Then, the clamping robot 404 clamps the rotor 600 and sends it to the second loading / unloading assembly 502, and then the second loading / unloading assembly 502 descends to the conveyor line 500 for unloading.
[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
