[0002] In the fields of motor manufacturing and power equipment maintenance, it is often necessary to use generator stator winding detection devices to evaluate winding performance. For example, in the production line of new energy vehicle drive motors, in order to ensure the operational reliability of the motors leaving the factory, parameters such as the inter-turn insulation and magnetic flux distribution of the stator windings often become key inspection items.

[0039] In this way, the conveying belt 11 can realize the conveying of the stator winding, complete the continuous detection process in cooperation with multiple fixed assemblies, and improve the detection efficiency; the support frame 12 provides a mounting carrier for the detection assembly, and the first electric push rod 13 can drive the detection assembly to ascend and descend, so as to adapt to the detection requirements of stator windings of different heights, and form a basic framework of “conveying-detection” integration.

[0040] The detection assembly comprises a shielding cover 14, a Hall sensor 15 for detecting the magnetic flux of the winding, and a detection ring 16, and the fixed assembly comprises a base 17 and multiple clamping plates 18.

[0041] In this way, the shielding cover 14 can isolate external electromagnetic interference, and ensure the detection accuracy of the Hall sensor 15 on the magnetic flux; the detection ring 16 integrates the functions of conduction and detection, and realizes the synchronization of energization and signal acquisition of the winding; the base 17 provides a mounting basis for the fixed assembly, and the multiple clamping plates 18 clamp the stator winding from different directions, so as to ensure the structural stability during detection and avoid detection errors caused by shaking.

[0042] The shielding cover 14 is mounted on the movable rod of the first electric push rod 13, the detection ring 16 is in sliding connection with the shielding cover 14, multiple conductive parts and multiple sliding blocks 27 are arranged on the detection ring 16, the conductive part comprises a conductive column 19 and a detection clamp for detecting the terminal of the winding, the conductive column 19 is arranged on the sliding block 27, and the detection clamp is arranged at one end of the conductive column 19, and the Hall sensor 15 is arranged on the clamping plate 18.

[0043] In this way, the shielding cover 14 can be adjusted quickly with the distance from the stator winding by ascending and descending with the first electric push rod 13; the detection ring 16 can move up and down along the stator winding by sliding through the driving structure; the sliding block 27 drives the conductive part to adjust the position, so that the detection clamp is connected to the terminal; and the Hall sensor 15 on the clamping plate 18 can detect the magnetic flux of the local area of the winding, so as to form a multi-dimensional detection of “overall + local” with the sensor of the detection assembly, and improve the comprehensiveness of defect identification. The Hall sensor 15 can be a SS495A type Hall sensor.

[0044] Further, the Hall sensors 15 are evenly distributed along the outer side wall of the clamping plate 18, and the number thereof is matched with the number of poles of the winding, for example, 4 groups of sensors are matched with a 4-pole winding, the detection surface of the sensor faces the inner side of the stator winding, the detection range covers the transition area between the end of the winding and the slot, and the radial magnetic flux distribution of the winding can be captured.

[0045] An image collector 49 is arranged on the detection ring 16, and the image collector 49 is electrically connected with an external control module.

[0046] In this way, the image collector 49 can identify the position coordinates of the winding terminal in real time and transmit signals to the control module, and the control module drives the driving component to adjust the alignment of the detection clamp, realizes automatic alignment without manual intervention, and solves the problems of low efficiency and large error of manual calibration of the traditional device. The image collector 49 can adopt a UTi640J model image collector.

[0047] Further, the image collector 49 is embedded in the lower end surface of the detection ring 16, the lens is directed obliquely downward at an angle of 35° with the vertical direction, and the built-in LED fill light (not shown in the figure) can complete terminal image shooting after the conveying belt 11 stops and identify the terminal profile.

[0048] The base 17 is provided with a clamping piece and a first driving motor 21, the first driving motor 21 is connected with the clamping piece, and the clamping plate 18 is connected with the clamping piece.

[0049] In this way, the first driving motor 21 provides power for the clamping piece, and the clamping piece drives the clamping plate 18 to move synchronously, realizing automatic clamping and loosening of the stator winding; compared with manual clamping, the clamping force of this structure is more uniform, and the clamping force can be controlled through motor parameters to avoid damage to the winding due to over-clamping or displacement during the detection process due to under-clamping.

[0050] The shielding cover 14 is provided with a sliding groove 22 on both sides, and the top of the shielding cover 14 is provided with two groups of second driving motors 23. The sliding groove 22 is provided with a lead screw 24, and one end of the two groups of lead screws 24 is connected with the output shaft of the two groups of second driving motors 23.

[0051] In this way, the sliding groove 22 provides guidance for the sliding of the detection ring 16, ensuring stable movement track; the second driving motor 23 drives the lead screw 24 to reverse, driving the detection ring 16 to translate along the sliding groove 22, and the distance between the detection ring 16 and the winding can be adjusted according to the winding diameter, adapting to different specifications of products and improving the compatibility of the device.

[0052] The detection ring 16 is sleeved on the two groups of lead screws 24, and the detection ring 16 is provided with a conductive plate 25 and a gear ring 26. The sliding block 27 is provided with a gear 28 at one end, the gear 28 is engaged with the gear ring 26, the top of the sliding block 27 is provided with a driving motor 29, and the output shaft of the driving motor 29 is provided on the gear 28.

[0053] In this way, the detection ring 16 is stably translated through the lead screw 24; the driving motor 29 drives the gear 28 to rotate along the gear ring 26, which can adjust the circumferential angle of the sliding block 27, so that the detection clamp can adapt to different distribution positions of the terminal in the circumferential direction, and realize three-dimensional alignment by cooperating with radial translation.

[0054] The bottom of each slider 27 is provided with a conductive block 31, and a plurality of groups of conductive grooves 32 are formed on the detection ring 16, and a first conductive sheet 33 is arranged in each conductive groove 32, and a first contact sheet 34 is arranged on one side of the conductive block 31, and the first contact sheet 34 is in contact with the first conductive sheet 33, and a second conductive sheet 35 is arranged at the bottom of the conductive groove 32, and a second contact sheet 36 is arranged at the bottom of the conductive block 31, and the second contact sheet 36 is in contact with the second conductive sheet 35.

[0055] In this way, the conductive block 31 is in sliding contact with the first conductive sheet 33 through the first contact sheet 34 and the second conductive sheet 35 through the second contact sheet 36, and the detection signal and the power supply are continuously conducted during the movement of the slider 27, which not only ensures the continuity of the conduction, but also does not limit the adjustment action of the slider 27, and solves the problem that the movement adjustment and stable conduction cannot be considered.

[0056] The second electric push rod 37 is arranged at the end of the slider 27 away from the gear 28, and the conductive column 19 is mounted on the movable rod of the second electric push rod 37, and the second electric push rod 37 is electrically connected with the second contact sheet 36.

[0057] In this way, the second electric push rod 37 can drive the conductive column 19 to extend and retract along the axial direction, adjust the axial distance between the detection clamp and the terminal, and adapt to the terminal extension length of different windings; the second electric push rod 37 is electrically connected with the second contact sheet 36, and can realize extension and retraction control through an external power supply and a control module, and complete closed-loop adjustment in cooperation with the signal of the image collector 49, and the control module can adopt an XC5-60R-E type control module.

[0058] The first conductive sheet 33 is electrically connected with an external detector, and the second conductive sheet 35 is electrically connected with an external power supply.

[0059] In this way, the first conductive sheet 33 forms a detection signal transmission loop, and conducts signals such as magnetic flux of the winding to the external detector, and the second conductive sheet 35 forms a power supply loop to pass the detection current to the winding, and the two are independent and integrated in the detection ring 16, so that the "power-on-detection" is performed synchronously, and the detection link switching time is reduced.

[0060] The end cover of the slider 27 is provided with an elastic contact ring 38, the elastic contact ring 38 is electrically connected with the first contact sheet 34, the conductive column 19 is in contact with the elastic contact ring 38, and a protective sleeve 39 is sleeved on the part of the conductive column 19 extending out of the slider 27.

[0061] In this way, the elastic contact ring 38 is always in contact with the conductive column 19 through its own elastic force, which ensures the stability of signal transmission during the extension and retraction of the conductive column 19 and avoids poor contact; the protective sleeve 39 is made of silicone rubber and has a corrugated tube structure, can be extended and retracted, and can prevent the operator from being electrically shocked by accidentally touching the conductive column 19 and isolate the pollution of external dust to the conductive part.

[0062] Further, the elastic contact ring 38 is a beryllium copper annular spring piece fixed along the inner wall of the end cover of the slider 27, and a plurality of protruding contacts are uniformly distributed on the inner side of the contact ring; the contact end of the contact ring is a spherical structure, which ensures that at least two protruding contacts are in contact with the conductive column 19 at all times when the conductive column 19 is extended or slightly deviated.

[0063] The detection clamp comprises a base 41, which is L-shaped, and a third electric push rod 42 is arranged on one side of the base 41. A push plate 51 is slidably arranged on the base 41 and connected with the movable rod of the third electric push rod 42. A third contact piece 43 is arranged on the base 41 and electrically connected with the conductive column 19.

[0064] In this way, the L-shaped base 41 provides sliding guidance for the push plate 51, the third electric push rod 42 drives the push plate 51 to move close to / distance from the base 41, thereby realizing clamping / loosening of terminals of different sizes; the third contact piece 43 conducts the current / signal of the conductive column 19 to the terminal, thereby ensuring the transmission of the energization and detection signal, and the structure is simple and the clamping is reliable.

[0065] Further, the conductive loop of the detection clamp is formed through the third contact piece 43 on the base 41-winding terminal-other third contact piece 43 on the base 41 of the detection clamp: a plurality of sliders 27 respectively connect different terminals of the winding, one of which is connected to the external detector through the conductive structure including the conductive block 31, the first contact piece 34, the first conductive piece 33, etc., and the other is connected to the external power supply through the corresponding conductive structure. After the current flows into the winding through the terminal, it is transmitted back to the external detector through the third contact piece 43 of the corresponding detection clamp and the conductive column 19, thereby forming a series loop with the winding as the core. Therefore, the push plate 51 only plays a mechanical clamping role and does not need to be provided with a contact piece, and the conductive function can be realized through single-point contact, i.e., the third contact piece 43 on the base 41 and the winding terminal, and the structure is simplified while ensuring the transmission of the detection signal.

[0066] A pressure sensor 48 is arranged on the base 41 and electrically connected with the third electric push rod 42 and the external control module.

[0067] In this way, the pressure sensor 48 can detect the clamping force of the push plate 51 on the terminal and feed back the signal to the control module, so that the control module adjusts the extension amount of the third electric push rod 42, so that the clamping force is stabilized in a preset range, thereby avoiding damage to the terminal due to over-clamping or excessive contact resistance due to under-clamping, forming a closed-loop control and improving the conductive reliability. The pressure sensor 48 can be an MPX5010 type pressure sensor.

[0068] The clamping member comprises two sets of adjusting rings 44 and a bidirectional screw rod 45, the two sets of adjusting rings 44 are sleeved on the bidirectional screw rod 45, the output shaft of the first driving motor 21 is connected with the bidirectional screw rod 45, and a plurality of clamping plates 18 are slidably provided with two sets of sliding blocks 46, the two sets of sliding blocks 46 are connected with the adjusting rings 44 through X-shaped hinges 47.

[0069] In this way, when the first driving motor 21 drives the bidirectional screw rod 45 to rotate, the two sets of adjusting rings 44 move in opposite directions synchronously along the bidirectional screw rod 45, the sliding blocks 46 are pushed to slide on the clamping plates 18 through the X-shaped hinges 47, a plurality of clamping plates 18 are driven to shrink / spread synchronously, the self-adaptive clamping of the stator winding with different outer diameters is realized, the X-shaped hinge 47 can ensure that the clamping force is uniformly distributed, the deformation of the winding caused by uneven force is avoided, and the fixing stability is improved.

[0070] Further, the X-shaped hinge 47 is formed by hinging two groups of metal rods in the middle, the top end of the hinge is connected with the middle part of the sliding block 46 through a pin shaft, the sliding block 46 slides along the slide rail on the side of the clamping plate 18, and the bottom end is connected with the outer side ear plate of the adjusting ring 44 through a pin shaft; when the bidirectional screw rod 45 drives the adjusting ring 44 to move towards each other, the included angle of the X-shaped hinge 47 is reduced from 60° to 30°, the sliding block 46 is pushed to slide along the slide rail to the two ends of the clamping plate 18, the clamping plate 18 is driven to shrink inward synchronously, and meanwhile the X-shaped hinge 47 is arranged in the through hole on the base 17, and the through hole plays a limiting role.

[0071] The specific use mode and effect of the embodiment are as follows:

[0072] The stator winding of the generator to be detected is placed on the conveying belt 11, and is conveyed to the detection station by the conveying belt 11, at this time, the first driving motor 21 on the base 17 drives the bidirectional screw rod 45 to rotate, the clamping plate 18 is driven to clamp the winding to complete positioning through the adjusting ring 44 and the X-shaped hinge 47; then the first electric push rod 13 drives the shielding cover 14 and the detection ring 16 to descend, the image collector 49 identifies the position of the terminal, the position of the detection ring 16 along the height direction of the stator winding is adjusted through the second driving motor 23 driving the screw rod 24, or the sliding block 27 is adjusted in the circumferential direction through the driving motor 29 driving the gear 28 to rotate along the tooth ring 26, the detection clamp is positioned; after positioning, the second electric push rod 37 pushes the conductive column 19 to extend out, the third electric push rod 42 drives the push plate 51 to clamp the terminal, the pressure sensor 48 feeds back the clamping force to the control module to ensure that the force is appropriate, the external power supply is powered on to the winding through the conductive structure, the Hall sensor 15 collects the magnetic flux data and transmits it to the detector to analyze the defects, and after the detection is completed, the components are reset, and the conveying belt 11 conveys the winding to the next station.

[0073] The external control module predefines a control process:

[0074] Alignment stage: after the image collector 49 transmits the terminal coordinates, the control module calculates the radial adjustment amount of the detection ring 16, drives the second drive motor 23 to rotate, the lead screw 24 drives the detection ring 16 to move and the sliding block 27 to move axially, drives the motor 29 to rotate, and the gear 28 drives the sliding block 27 to move circumferentially;

[0075] Clamping stage: the pressure sensor 48 transmits the clamping force signal in real time, when the force value reaches 10±1N, the control module immediately sends a stop signal to the third electric push rod 42, and if the preset value is not reached within 3 seconds, an alarm is triggered;

[0076] Detection stage: the control module synchronously receives the signals of the Hall sensor 15 and the external detector, when the magnetic flux deviation exceeds ±5% or the detection current is abnormal (such as short circuit leading to sudden increase of current), the winding is marked as unqualified, and feedback is given through the indicator light.

[0077] The specific parameters (such as the type of Hall sensor, angle, size, pressure threshold, control accuracy, etc.) mentioned in the above embodiments are only used to more clearly explain the structural principle, cooperative relationship and implementation mode of the utility model, to assist the technical personnel in the art in understanding the cooperation logic and function realization process of each component, and do not limit the protection scope of the utility model.
