Description

Technical Field

[0001] The present application relates to the technical field of motor detection, and more specifically, to a rotor high-voltage testing device. Background Art

[0002] As the core component of a motor's energy conversion, the rotor's insulation performance directly determines its operational safety and service life. Therefore, during rotor production, its insulation strength is rigorously inspected through high-voltage testing to eliminate substandard products with insulation defects.

[0003] Currently, rotor high-voltage testing mostly relies on traditional manual operations or single-station manual tooling. In practical applications, this approach has significant technical limitations: on the one hand, the rotor needs to be manually placed at the test station during testing, but the accuracy of manual placement is difficult to guarantee. The relative position deviation between the rotor and the test electrode can easily lead to distortion of the test data, affecting the accurate judgment of the rotor's insulation performance. On the other hand, the loading, positioning, testing, unloading, and sorting of defective products during the test process must be completed manually. The operation process is cumbersome and labor-intensive, resulting in low test efficiency and difficulty matching the pace of mass production. In addition, the single-station manual tooling has a fixed structure and a single function, and cannot be connected to the front-end and back-end automated production lines. It has extremely poor scalability and cannot meet the current production needs of the motor manufacturing industry for upgrading to intelligent and automated production. Summary of the Invention

[0049] Figure 1 FIG. 1 is a front structural diagram of a rotor high-voltage testing device provided in an embodiment of the present application. Figure 2 FIG. 1 is a schematic diagram of the three-dimensional structure of the rotor high-voltage testing device provided in an embodiment of the present application. Figure 3 The figure shows a three-dimensional structural diagram of the positional relationship among the conveying mechanism, the high-voltage testing mechanism and the buffer mechanism in the embodiment of the present application.

[0050] Please refer to Figures 1 to 3 An embodiment of the present application provides a rotor high-voltage testing device, including a frame 100 , a conveying mechanism 200 , a high-voltage testing mechanism 300 and a cache mechanism 400 .

[0051] The conveying mechanism 200 is used to convey the rotor from the first station P1 to the second station P2 along the first direction D1 relative to the frame 100. A testing station Pd and a sorting station Pw are sequentially provided on the conveying path between the first station P1 and the second station P2.

[0052] The high-voltage testing mechanism 300 is located at the testing station Pd in ​​the first direction D1 . The high-voltage testing mechanism 300 is used to perform a high-voltage test on the rotor located at the testing station Pd.

[0053] The cache mechanism 400 is located at the sorting station Pw in the first direction D1. The cache mechanism 400 includes a cache bin 410, a limit stop 420 and a cache drive 430. The cache drive 430 is used to transfer the rotor that is determined to be unqualified by the high-voltage testing mechanism 300 and is at the sorting station Pw to the cache bin 410. The limit stop 420 is used to confine the unqualified rotors stored in the cache bin 410 to the cache bin 410.

[0054] In the rotor high-voltage testing device provided in this embodiment, the conveying mechanism 200 conveys the rotor from the first station P1 through the test station Pd and the sorting station Pw to the second station P2 in sequence. The conveying mechanism 200 realizes the automatic conveyance of the rotor between the stations along the first direction D1, replacing the traditional method of manually placing the rotor, avoiding the position deviation problem caused by manual operation, and ensuring that the rotor can maintain precise positioning when passing through the high-voltage testing mechanism 300, thereby ensuring the accuracy and consistency of the high-voltage test results. Secondly, the high-voltage testing mechanism 300 is located at the test station Pd. The high-voltage testing mechanism 300 completes the test at the test station Pd (before the sorting station Pw). The entire process does not require manual intervention in the loading, conveying and preliminary unloading links, reducing manual operation steps, significantly shortening the rotor test cycle, and can adapt to the rhythm of mass production and meet the needs of efficient production. Furthermore, the cache mechanism 400 is configured to automatically transfer and store rotors at the test station Pd. The cache driver 430 can accurately move rotors that have been determined to be unqualified by the high-voltage test mechanism 300 from the conveying mechanism 200 to the cache bin 410. The position limiter 420 ensures that unqualified rotors are stably stored in the cache bin 410, avoiding the tediousness and omissions of manual sorting. At the same time, qualified rotors can continue to be transported to the second station P2 via the conveying mechanism 200, thus achieving integrated automation of testing and sorting and improving the continuity of the production line. In addition, the device, through the modular combination of the conveying mechanism 200, the high-voltage test mechanism 300, and the cache mechanism 400, can be conveniently connected to the front-end and back-end automated production lines, breaking away from the limitations of traditional single-station manual tooling with a single function and incompatibility with automated production. It improves the accuracy and efficiency of the rotor high-voltage test results, can meet the needs of the motor manufacturing industry for upgrading to intelligence and automation, and has broad application prospects.

[0055] See also Figures 1 to 3 In some embodiments, the first direction D1 is parallel to the horizontal plane; the cache drive member 430 is configured as a top-loading cylinder, the cache bin 410 is located above the top-loading cylinder, the cache bin 410 is extended along the vertical direction V, and the limit stop 420 is arranged at the bottom of the cache bin 410. The limit stop 420 is a one-way limiting structure, which is used to allow the rotor moving from bottom to top to pass through and enter the cache bin 410, and prevent the rotor moving from top to bottom from escaping from the cache bin 410.

[0056] In this embodiment, the conveying path of the conveying mechanism 200 is parallel to the horizontal plane, the buffer bin 410 is extended along the vertical direction V, and the buffer bin 410 is arranged above the pushing cylinder, so that the pushing action precisely corresponds to the entrance position of the buffer bin 410. The pushing cylinder is used as the cache driving component 430 to accurately and quickly push the unqualified rotor from the test station Pd upward to the buffer bin 410, reducing the path deviation during the rotor transfer process and ensuring that the rotor can smoothly enter the buffer bin 410.

[0057] In addition, the buffer bin 410 extending along the vertical direction V can fully utilize the vertical space and increase the storage capacity of unqualified rotors within a limited equipment footprint, which is particularly suitable for scenarios where the production line space is compact.

[0058] The stopper 420, a one-way stopper located at the bottom of the buffer chamber 410, allows the rotor, pushed by the ejection cylinder, to enter the buffer chamber 410 smoothly from bottom to top. It also effectively prevents the rotor from escaping from the buffer chamber 410 from top to bottom due to its own gravity or slight external vibrations, thus stably limiting the position of unqualified rotors. This one-way stopper design eliminates the need for additional locking controls and achieves the limit function solely through mechanical structure. This not only simplifies the control logic, but also reduces the probability of failure and improves the operational stability of the buffer mechanism 400.

[0059] In summary, this embodiment improves the operating efficiency, space utilization and structural reliability of the device while making the entire defective product sorting and storage process more efficient and stable through the detailed design of the setting direction of the cache bin 410, the conveying direction of the conveying mechanism 200 (i.e., the direction from the first workstation P1 to the second workstation P2 along the first direction D1), the cache drive 430 and the limit stop 420.

[0060] Figure 4 The figure shows a schematic top view of the positional relationship among the conveying mechanism, the high-voltage testing mechanism and the buffer mechanism in the embodiment of the present application. Figure 5 Shown is a schematic structural diagram of the cache bin in an embodiment of the present application.

[0061] See also Figures 1 to 5 In some embodiments, the cache bin 410 includes two cache units arranged opposite to each other along a second direction D2, where the second direction D2 is parallel to the horizontal plane and perpendicular to the first direction D1; each cache unit includes two receiving plates 411 arranged opposite to each other along the first direction D1 and extending along the vertical direction V, and a first space 412 is formed between the two receiving plates 411, and the first space 412 is adapted to the rotating shaft of the rotor and for it to pass through. A second space 413 is provided between the two cache units, and the second space 413 is adapted to the iron core of the rotor and for it to pass through. The first space 412 and the second space 413 are connected to form a channel for the entire rotor to pass through and accommodate.

[0062] In the embodiment, the cache bin 410 is provided with two cache units arranged opposite to each other along the second direction D2, and a second space 413 is arranged between the two cache units, and each cache unit is provided with two receiving plates 411 arranged opposite to each other along the first direction D1, thereby forming the first space 412 and the second space 413 matched with the rotor structure. The first space 412 is adapted to the rotating shaft of the rotor, and the second space 413 is adapted to the core of the rotor, and the two spaces are connected to form a complete channel; the structure design can form targeted constraints on different parts of the rotor, and the four receiving plates 411 of the cache bin 410 limit the horizontal activity freedom of the rotor, thereby avoiding the shaking or deviation of the rotor in the cache bin 410, ensuring that the unqualified rotor maintains a stable posture during storage, and further improving the reliability of the cache mechanism 400.

[0063] Figure 6 Fig. 2 shows a structural schematic diagram of the receiving plate in the embodiment of the application, Figure 7 Fig. 3 shows a structural schematic diagram of the cache bin in the embodiment of the application, Figure 6 Fig. 4 shows an enlarged view of part A in Fig. 3.

[0064] Referring to Figures 5 to 7 In some embodiments, in each cache unit, a mounting groove 4111 is formed on the bottom side of one receiving plate 411 and close to one side of the other receiving plate 411, the limiting stopper 420 includes a blocking strip 421 and a torsion spring (not shown in the figure), the blocking strip 421 is arranged between the two receiving plates 411, and a first end of the blocking strip 421 is rotatably mounted in the mounting groove 4111 through a pin shaft 4112, and a second end of the blocking strip 421 is a free end;

[0065] The torsion spring is sleeved on the pin shaft 4112, and one end of the torsion spring abuts against the second end of the blocking strip 421, and the other end of the torsion spring abuts against the inner wall of the mounting groove 4111;

[0066] The limiting stopper 420 has a first state and a second state; in the first state, the second end of the blocking strip 421 is used to abut against the other receiving plate 411, or a first gap is formed between the second end of the blocking strip 421 and the other receiving plate 411, the first gap is much smaller than the diameter of the rotating shaft of the rotor to block the rotating shaft, and the torsion spring is in a natural state; in the second state, the second end of the blocking strip 421 is used to be upwardly pushed by the rotating shaft of the rotor to form a second gap between the second end of the blocking strip 421 and the other receiving plate 411 for the rotating shaft of the rotor to pass through, and the torsion spring is deformed under pressure.

[0067] The working process of the buffer bin 410 of the embodiment is as follows: when the unqualified rotor is conveyed to the sorting station Pw by the conveying mechanism 200 and is pushed upward by the buffer driving member 430 (a top material air cylinder) to the bottom of the buffer bin 410, the rotor shaft first contacts the second end of the blocking strip 421, at this time, the upward pushing force of the rotor shaft forces the blocking strip 421 to rotate around the pin shaft, so that the second end of the blocking strip 421 swings away from the opposite side receiving plate 411, the limiting stop member 420 is switched from the first state to the second state, that is, the second gap for the rotor shaft to pass through is formed between the blocking strip 421 and the other receiving plate 411, and the torsional spring member is deformed due to the rotation of the blocking strip 421. As the rotor continues to move upward, the rotor shaft of the rotor enters the first space 412 of the buffer bin 410 through the second gap, and the rotor core passes through the second space 413 between the two buffer units, and the entire rotor is completely in the buffer bin 410. When the rotor passes through, the pushing force of the rotor shaft on the blocking strip 421 disappears, the blocking strip 421 is reset under the action of the spring restoring force driven by the torsional spring member, and the limiting stop member 420 is switched back to the first state, that is, the second end of the blocking strip 421 abuts against the other receiving plate 411 or forms a first gap smaller than the diameter of the rotor shaft between the other receiving plate 411, so as to prevent the rotor in the buffer bin 410 from falling downward due to gravity and other factors.

[0068] In the embodiment, the one-way passage control of the unqualified rotor is realized by the cooperation of the blocking strip 421 and the torsional spring member, only the rotor is allowed to enter the buffer bin 410 from bottom to top, the falling of the rotor is effectively prevented, and the unqualified rotor is stably stored in the buffer bin 410. Secondly, the installation position and size design (such as the first gap being much smaller than the diameter of the rotor shaft) of the limiting stop member 420 are matched with the receiving plate 411 of the buffer unit and the structure of the rotor shaft, which not only ensures the effective blocking of the rotor, but also avoids interference with the process of the rotor entering the buffer bin 410. In addition, the state switching of the limiting stop member 420 is realized without additional driving devices by the elastic deformation and reset characteristics of the torsional spring member, which is simple in structure, stable and efficient in operation.

[0069] Referring to Figures 1 to 3 In some embodiments, the high-voltage test mechanism 300 includes a lifting driving member 310 and a pressure resistance instrument 320, the pressure resistance instrument 320 is used for high-voltage test of the rotor, the lifting driving member 310 is used for driving the rotor to reciprocate between the to-be-tested station Pd and the test station Pt, the test station Pt is the test working position of the pressure resistance instrument 320 and is located on one side of the to-be-tested station Pd in the third direction, and the third direction is not parallel to the first direction D1.

[0070] It should be understood that the test station Pt is located on one side of the test station Pd along the third direction. In specific implementation, the third direction may preferably be the vertical direction V, in which case the test station Pt and the test station Pd are distributed vertically. Of course, the third direction may also be set to other directions parallel to the horizontal plane, so that the test station Pt and the test station Pd are distributed laterally on the horizontal plane. In specific implementation, the setting orientation of the test station Pt can be flexibly selected according to the actual space constraints of the production line: when the horizontal layout of the workshop is compact, the test station Pt is arranged in the vertical direction V, which can reduce the floor space by utilizing the three-dimensional space. When it is necessary to connect with the peripheral equipment on the same horizontal plane, a horizontal lateral layout can be selected to form a coherent planar production flow.

[0071] Furthermore, because the withstand voltage tester 320 outputs a high-voltage electrical signal during high-voltage testing, the high-voltage testing mechanism 300 may further include a housing 340. The withstand voltage tester 320 and the test station Pt may be located within the space within housing 340. Housing 340 effectively isolates the high-voltage area, preventing operators from accidentally contacting live components and reducing the risk of electric shock. Furthermore, housing 340 blocks sparks and arcs that may be generated during testing, preventing interference and damage to surrounding equipment or personnel. This significantly improves the operational safety of the device and complies with industrial safety regulations. Furthermore, housing 340 reduces the impact of environmental factors on the testing process. For example, it blocks dust and oil from the workshop from entering the test station Pt, preventing them from adhering to the test end of the withstand voltage tester 320 or the test area of ​​the rotor, ensuring good electrode contact. Furthermore, housing 340 isolates the withstand voltage tester 320 from external airflow, vibration, and electromagnetic interference to a certain extent, making the test data from the withstand voltage tester 320 more stable, reducing test errors caused by environmental fluctuations, and further ensuring the accuracy of high-voltage test results.

[0072] In this embodiment, the lift-drive element 310 drives the rotor back and forth between the test station Pd and the testing station Pt, ensuring that the rotor can be transferred to the testing station Pt without interruption during the normal conveying path. This design not only avoids spatial interference between the high-voltage testing mechanism 300 and the conveying mechanism 200, but also ensures a continuous "conveying-testing-return conveying" process. After testing, the rotor can be returned to the conveying path by the lift-drive element 310 and continue to participate in subsequent sorting or conveying steps, significantly improving overall production efficiency.

[0073] Figure 8 The figure shows a schematic diagram of the assembly structure of the adjustment member and the pressure tester in the embodiment of the present application.

[0074] See also Figure 1 、 Figure 3 and Figure 8In some embodiments, the high voltage testing mechanism 300 further includes an adjusting member 330 , which is connected to the withstand voltage tester 320 and is used to adjust the distance between the withstand voltage tester 320 and the test station Pt.

[0075] A specific implementation of the adjustment member 330 in this embodiment is as follows: the adjustment member 330 includes a guide rod 331, a connecting block 332, and a locking member 333, wherein the pressure tester 320 is fixedly connected to the connecting block 332, the connecting block 332 and the guide rod 331 form a sliding fit structure, and the locking member 333 is used to position and lock the connecting block 332 to a specific position of the guide rod 331 after the adjustment is completed. The specific adjustment process is as follows: when it is necessary to adjust the position of the pressure tester 320, the locking member 333 is released to allow the connecting block 332 to slide freely along the guide rod 331, and the position of the pressure tester 320 is adjusted by changing the position of the connecting block 332 on the guide rod 331; after the pressure tester 320 is adjusted to the target position, the locking member 333 is operated to fix the connecting block 332 relative to the guide rod 331, so that the pressure tester 320 can be maintained in the set position, ensuring that its relative position to the test station Pt is stable. Of course, the specific structure of the adjustment member 330 is not limited to the above-mentioned form, and other adjustment structures commonly used in this field (such as a spiral adjustment structure, a guide rail slider adjustment structure, etc.) can also be adopted. As long as the position fine-tuning function of the pressure gauge 320 can be achieved, this application does not limit this.

[0076] In this embodiment, for rotors of different models or sizes, there are differences in the distance between the parts that need to be tested under high voltage (such as the winding ends) and the test reference surface. The adjusting member 330 can flexibly adjust the distance between the withstand voltage instrument 320 and the test station Pt, so that the test electrodes of the withstand voltage instrument 320 can be accurately aligned with the test parts of rotors of different specifications, ensuring good test contact. In addition, during the installation and debugging stage of the device, the position of the withstand voltage instrument 320 can be quickly adjusted by the adjusting member 330, so that it can be accurately matched with the rotor that is transferred to the test station Pt by the lifting drive member 310, thereby shortening the debugging cycle; in daily maintenance, if the position of the withstand voltage instrument 320 or related components changes, it can also be conveniently corrected through the adjusting member 330, without the need for large-scale disassembly or adjustment of the entire high-voltage test mechanism 300, thereby reducing the difficulty and workload of maintenance, improving the operation and maintenance efficiency of the equipment, and providing higher flexibility and reliability for the automated testing process.

[0077] Figure 9 The figure shows the connection structure diagram of the second driving member and the movable gear plate in the embodiment of the present application. Figure 10 Shown Figure 3 A partial enlarged view of point B in the middle.

[0078] See also Figure 2 、 Figure 3 、 Figure 9 and Figure 10In some embodiments, the conveying mechanism 200 includes a movable gear group 210, a fixed gear group 220 installed on the frame 100, a first driving member 230 and a second driving member 240;

[0079] The fixed gear set 220 includes two fixed gear plates 221 extending in a first direction D1 and arranged opposite to each other in a second direction D2. The first direction D1 and the second direction D2 are perpendicular to each other and parallel to the horizontal plane.

[0080] The movable gear assembly 210 includes two movable gear plates 211, each of which is parallel to a corresponding fixed gear plate 221. The movable gear plates 211 and the corresponding fixed gear plates 221 are both provided with latches with fixed tooth spacing, and the tooth spacing and tooth width of the latches are equal. The latches are used to accommodate and support the rotating shaft of the rotor. The movable gear plates 211 and the corresponding fixed gear plates 221 are arranged along the axial direction of the rotor.

[0081] The first driving member 230 is used to drive the two movable row gear plates 211 to reciprocate in the vertical direction V, and the second driving member 240 is used to drive the two movable row gear plates 211 to reciprocate in the first direction D1. The first driving member 230 and the second driving member 240 work alternately.

[0082] It should be understood that the movable row of toothed plates 211 and the corresponding fixed row of toothed plates 221 are arranged along the axial direction of the rotor. As a specific implementation of this embodiment, the movable row of toothed plates 211 and the fixed row of toothed plates 221 can be arranged sequentially along the second direction D2 from the end of the rotor shaft toward the center, that is, the movable row of toothed plates 211 are positioned closer to the end of the rotor shaft than the corresponding fixed row of toothed plates 221.

[0083] In another embodiment, see Figure 10 , two fixed row gear plates 221 can be set to further improve the stability of the rotor during transportation by increasing the bearing points. At this time, the movable row gear plate 211 can be placed between the two fixed row gear plates 221. The two fixed row gear plates 221 can form a lateral limit for the movable row gear plate 211 in the second direction D2, effectively restraining its displacement in the second direction D2 during movement, thereby enhancing the movement stability of the movable row gear plate 211. In addition, this "double fixed row gear plates 221 clamping the movable row gear plate 211" structural design also has a protective function: the two fixed row gear plates 221 can form a physical barrier for the movable row gear plate 211, reducing the probability of direct contact between staff or other objects and the movable row gear plate 211, which not only reduces the risk of external interference with the movable row gear plate 211, but also improves the operational safety during equipment operation and testing.

[0084] In this embodiment, both the movable tooth plate 211 and the corresponding fixed tooth plate 221 are equipped with latches with fixed tooth spacing. The latches provided on the movable tooth plate 211 are denoted as movable latches 2111, and the latches provided on the fixed tooth plate 221 are denoted as fixed latches 2211. The latches on the movable tooth plate 211 and the fixed tooth plate 221 have equal tooth spacing and tooth width. The fixed latches 2211 and the movable latches 2111 can precisely accommodate and stably support the end of the rotor's shaft, providing a reliable support base for the rotor. Furthermore, the tooth walls of the latches can limit the rotor's shaft, effectively limiting its displacement along the first direction D1 during transportation, thereby ensuring that the rotor always moves smoothly along the first direction D1 and preventing position deviations caused by shaking that could adversely affect subsequent testing or sorting processes.

[0085] In this embodiment, the first driving member 230 drives the movable row of gear plates 211 to reciprocate in the vertical direction V, thereby enabling the movable row of gear plates 211 to contact or separate from the rotor; the second driving member 240 drives it to reciprocate in the first direction D1, thereby driving the rotor to move along the conveying direction. The specific working process is as follows: the first driving member 230 drives the movable row gear plate 211 to make it rise, the movable latch 2111 undertakes the rotating shaft of the rotor, and makes the rotating shaft of the rotor disengage from the fixed latch 2211 of the fixed row gear plate 221, and then the second driving member 240 drives it to move forward along the first direction D1 (i.e. along the conveying direction) by a tooth pitch, and then the first driving member 230 drives the movable row gear plate 211 again to make it descend, and places the rotor in the next fixed latch 2211 of the fixed row gear plate 221; finally, the second driving member 240 drives the movable row gear plate 211 again to move it backward along the first direction D1 (i.e. in the opposite direction of the conveying direction) by a tooth pitch, and the movable row gear plate 211 is reset, completing one stepping conveying. As mentioned above, the movable tooth plate 211 performs a cyclic action of "rising-forward-falling-backward", and cooperates with the fixed tooth 2211 of the fixed tooth plate 221 to position the rotor, so that the rotor can be accurately moved to each station according to the preset beat (such as the first station P1 to the test station Pd, the test station Pd to the second station P2), and the conveying accuracy is significantly improved, meeting the strict requirements of high-voltage testing on the rotor position. In the above process, the first drive member 230 and the second drive member 240 work alternately, and the automatic action of the movable tooth group 210 can be realized through program control. There is no need for manual intervention in the rotor conveying process, which not only reduces the inefficiency caused by manual operation, but also ensures the consistency of the conveying rhythm, so that the rotor can continuously enter the test process, greatly improving the overall operating efficiency of the device and adapting to the needs of batch testing.

[0086] In summary, this embodiment achieves precise, automated and stable rotor transportation through the coordinated cooperation of the movable gear group 210, the fixed gear group 220 and the first drive member 230 and the second drive member 240, which not only ensures the smooth progress of subsequent testing links, but also improves the operating efficiency and scope of application of the device, and provides an efficient transportation solution for the automated production line of rotor high-voltage testing.

[0087] See also Figure 3 、 Figure 4 and Figure 9 In some embodiments, the two movable tooth plates 211 are connected by a connection group, which includes a first connecting rod 2212 and a second connecting rod 2213, the first driving member 230 is connected to the first connecting rod 2212, and the second driving member 240 is connected to the second connecting rod 2213.

[0088] In specific implementations, because the movable toothed plate 211 extends along the first direction D1, its rigidity in this direction is relatively weak. To enhance structural stability, multiple first connecting rods 2212 may be provided. In one specific embodiment, two first connecting rods 2212 are provided, one mounted at each end of the movable toothed plate 211 in the first direction D1. This multi-point support effectively improves the overall rigidity of the movable toothed plate 211 in the extension direction, preventing deformation due to stress and thus affecting conveying accuracy.

[0089] In this embodiment, the two movable rows of toothed plates 211 are rigidly connected by a first connecting rod 2212 and a second connecting rod 2213, making the two a whole. When the first driving member 230 drives the first connecting rod 2212, the two movable rows of toothed plates 211 can maintain a completely consistent lifting rhythm and displacement in the vertical direction V; similarly, when the second driving member 240 is driven by the second connecting rod 2213, the translational movement of the two in the first direction D1 can also be precisely synchronized. This synchronization avoids positional deviation of a single movable row of toothed plates 211 due to uneven force or drive delay, ensuring that the two end shafts of the rotor can be simultaneously received, transferred, and placed by the movable row of toothed plates 211, effectively preventing the rotor from tilting, getting stuck, or falling during transportation, greatly improving the stability and reliability of transportation.

[0090] See also Figure 3 and Figure 10 In some embodiments, the conveying mechanism 200 further includes two limiting plates 250 , each limiting plate 250 corresponding to and parallel to a fixed tooth plate 221 , and the limiting plate 250 is used to abut against the end surface of the rotating shaft of the rotor.

[0091] In this embodiment, the limit plate 250 forms an axial constraint on the rotor from both ends of the rotating shaft, effectively limiting the displacement of the rotor in the second direction D2, and preventing the rotor from moving along the axial direction of the rotating shaft due to vibration, inertia or impact of the driving member during transportation, thereby ensuring that the rotor is always on the preset conveying path and maintains precise docking with the teeth of the fixed tooth plate 221 and the movable tooth plate 211, providing a pre-guarantee for the position accuracy of subsequent high-voltage testing, defective product sorting and other links.

[0092] See also Figure 1 and Figure 2 In some embodiments, the rotor high-voltage testing device further includes an electronic control component, which includes a first sensor, a second sensor, a third sensor, and a controller 510. The first sensor is used to detect whether the rotor is located at the test station Pd, the second sensor is used to detect whether the rotor is located at the test station Ps, and the third sensor is used to detect whether the rotor is located at the sorting station Pw. The controller 510 is electrically connected to the first sensor, the second sensor, the third sensor, the first drive member 230, the second drive member 240, the lifting drive member 310, the cache drive member 430, and the voltage tester 320.

[0093] In this embodiment, the first, second, and third sensors respectively monitor the rotor's position in real time at the test station Pd, the test station Ps, and the sorting station Pw. This allows for precise monitoring of the rotor's status at each key station, providing accurate positional information for subsequent operations. The controller 510 is electrically connected to each sensor and the actuators (the first actuator 230, the second actuator 240, the lifting actuator 310, and the buffer actuator 430). Based on the rotor position information provided by the sensors, the controller automatically triggers the corresponding actuators. For example, when the first sensor detects that the rotor is located at the test station Pd, the controller 510 can control the lifting drive 310 to move the rotor to the test station Ps, perform high-voltage testing on the rotor through the pressure tester 320, and transmit the test result signal to the controller 510; when the second sensor detects the rotor and completes the test after a preset time, the controller 510 can coordinate the lifting drive 310 to move the rotor back to the test station Ps. After the rotor reaches the sorting station Pw along the conveying direction, the cache drive 430 is selected to work according to the corresponding test result transmitted by the pressure tester 320. When the test result is unqualified, the controller 510 can control the cache drive 430 to transfer the rotor to the cache bin 410; when the test result is qualified, the cache drive 430 does not work, and the conveying mechanism 200 continues to realize the automatic linkage of the entire test process, reducing manual intervention. Real-time monitoring of the rotor position by the sensor and timely response of the controller can avoid operational errors caused by inaccurate rotor position information, ensure smooth operation of each drive component, improve the continuity and reliability of the operation of the entire rotor high-voltage test device, and thus improve the test efficiency and the accuracy of the test results.
