Description

Technical Field

[0001] The present invention relates to the field of automation technology, and in particular to an all-in-one machine for magnetizing and detecting surface magnetism of a motor rotor. Background Art

[0002] With the rapid development of the new energy vehicle industry, the performance and reliability of motors, as one of their core components, are receiving increasing attention. Permanent magnet synchronous motors (PMSMs) have become the mainstream choice for new energy vehicle motors due to their high power density, high efficiency, compact size, and low noise. The magnetization process of the rotor, a key component of a PMSM, has a crucial impact on the motor's overall performance and quality.

[0003] Currently, manual magnetization is the primary method for surface magnetization of motor rotors. This method presents numerous problems: First, manual magnetization consumes significant time and human resources, resulting in low magnetization efficiency and difficulty meeting the needs of large-scale production. Second, the instability of manual operation can easily lead to insufficient magnetization accuracy, affecting the performance and consistency of the motor rotor. Furthermore, manual magnetization can pose safety risks, such as magnetic field leakage or equipment damage due to improper operation.

[0004] At the same time, the rotor surface magnetic detection of motors mainly adopts manual detection, which usually consumes a lot of time and human resources, resulting in low detection efficiency. With the development of Industry 4.0 and intelligent manufacturing, manual detection methods are difficult to seamlessly connect with automated production lines and intelligent detection systems, which limits the optimization and upgrading of production processes.

DETAILED DESCRIPTION

[0032] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figures 1 to 11 As shown, the present invention provides an integrated machine for magnetizing and detecting surface magnetism of a motor rotor. In one embodiment, the machine comprises a workbench 1; a work position is provided on the workbench 1, and the work position is used to place a magnetizing coil assembly 2; a rotor lifting device 3 is further installed at the bottom of the workbench 1 corresponding to the work position, and the rotor lifting device 3 partially passes through the magnetizing coil assembly 2; a pressing device 4 is further installed at the top of the workbench 1 corresponding to the work position; a support frame 5 is installed on the top of the workbench 1 near the work position, and a surface magnetism detection device 6 and an appearance detection device 7 are also installed on the support frame 5.

[0034] In this embodiment, a frame is also included, and a workbench 1 is installed in the frame; a cabinet door is also provided on the front of the frame, and a display screen, keyboard and mouse are also installed on the frame to facilitate operation by the staff. A three-color indicator light is also provided on the top of the frame, and foot cups are also installed at the four corners of the bottom of the frame; the top of the workbench 1 is also provided with two guide grooves spaced parallel to each other along its length, and the magnetizing coil assembly 2 includes a carrier plate and a magnetizing coil installed on the top of the carrier plate; guide pins are provided at the two sides of the bottom of the carrier plate corresponding to the guide grooves, and the guide pins are inserted into the guide grooves. The magnetizing coil can be pushed to the working position by manually pushing the carrier plate; when working, first select the type of motor rotor to be magnetized The corresponding magnetizing coil assembly 2 is then manually pushed to the working position (when pushing the carrier, it can be guided by the guide pins and guide grooves). Subsequently, the electronic rotor to be tested is placed on the rotor lifting device 3, and the pressing device 4 is pressed down to limit the rotor downward. Subsequently, the rotor lifting device 3, the rotor and the pressing device 4 are synchronously lowered so that the rotor is placed in the magnetizing coil and magnetization is started. After magnetization is completed, the rotor lifting device 3, the rotor and the pressing device 4 are synchronously raised so that the rotor rises from the magnetizing coil to the predetermined detection position. Finally, the surface magnetism detection device 6 and the appearance detection device 7 detect the surface magnetism and surface appearance of the rotor.

[0035] In one embodiment, the pressing device 4 includes a pressing fixed frame 41, a pressing rotating seat 42, a pressing rod 43, and a pressing pin assembly 44; the pressing fixed frame 41 is installed on the workbench 1; a pressing driving mechanism 45 is installed on the pressing fixed frame 41, and the pressing driving mechanism 45 is also driven by a pressing lifting plate 46; a first bearing seat 461 is installed on the pressing lifting plate 46, and a tapered roller bearing 466 is installed on the upper and lower parts of the first bearing seat 461; the pressing rotating seat 42 is arranged through the first bearing seat 461, and the pressing rotating seat 42 is connected to the workbench 1; The middle part is connected to two tapered roller bearings 466; the lower pressure rod 43 is installed on the bottom of the lower pressure rotating seat 42, and the bottom of the lower pressure rod 43 is conical; the bottom of the lower pressure rotating seat 42 is also connected to the upper workholding seat 47, and the lower pressure rod 43 is located in the upper workholding seat 47; the lower pressure pin assembly 44 is installed on the lower pressure rotating seat 42, and one end of the lower pressure pin assembly 44 is movably passed through the bottom of the upper workholding seat 47 and extended outward; a rotation drive mechanism 48 is also installed on the lower pressure lifting plate 46, and the upper part of the lower pressure rotating seat 42 is connected to the rotation drive mechanism 48.

[0036] In this embodiment, a lifting guide rod is connected between the four corners of the bottom of the pressing fixed frame 41 and the workbench 1, a copper sleeve is installed at each of the diagonal positions of the top of the pressing lifting plate 46, and a linear bearing is installed at each of the other diagonal positions of the top of the pressing lifting plate 46. The pressing lifting plate 46 is slidably connected to the four lifting guide rods via two copper sleeves and two linear bearings. By installing the copper sleeves and linear bearings at the diagonal positions of the pressing lifting plate 46, the uniformity and smoothness of the force applied to the pressing lifting plate 46 can be ensured when it is lifted or lowered. The pressing drive mechanism 45 includes a servo motor module installed on the top of the pressing fixed frame 41, and a pressing connecting seat installed on the top of the pressing lifting plate 46 and connected to the servo motor module. Driven by the servo motor module, the downward pressing rotating seat 42 can be raised and lowered through the downward pressing connecting seat and the downward pressing lifting plate 46, so that the downward pressing rod 43 can limit the downward pressing of the motor rotor; a pin hole is provided on the motor rotor, and when the downward pressing rod 43 presses the rotor, it will first perform a pin-finding action, that is, the downward pressing pin assembly 44 may not be aligned with the pin hole at this time. At this time, the rotary driving mechanism 48 will drive the downward pressing rotating seat 42 to drive the downward pressing pin assembly 44 to rotate until the downward pressing pin assembly 44 is inserted into the pin hole to complete the product positioning. At this time, when the rotary driving mechanism 48 drives the downward pressing rotating seat 42 to rotate, the motor rotor can be driven to rotate through the downward pressing pin assembly 44 to perform a return to origin (return to origin, adjust the rotor magnetization position) operation.

[0037] Furthermore, in this embodiment, the bottom of the downward-pressing rotating seat 42 is also connected to a first connecting seat 49, and the bottom of the first connecting seat 49 is sequentially arranged with a first deep groove ball bearing, a first spacer, a first thrust ball bearing, a second spacer, and a second deep groove ball bearing from top to bottom. The downward-pressing rod 43 is mounted on the first connecting seat 49, and the upper portion of the downward-pressing rod 43 is sequentially connected with the first deep groove ball bearing, the first spacer, the first thrust ball bearing, the second spacer, and the second deep groove ball bearing from top to bottom. The middle outer wall of the downward-pressing rod 43 is provided with a bearing step, and the second deep groove ball bearing is arranged on the bearing step. The upper portion of the downward-pressing rod 43 is connected to the above three bearings and can rotate relative to the first connecting seat 49. After the downward-pressing rod 43 is pressed to the top of the rotor, when the downward-pressing rotating seat 42 drives the motor rotor to rotate via the downward-pressing pin assembly 44, the downward-pressing rod 43 can rotate synchronously with the rotor relative to the bearings, thereby preventing friction resistance on the motor rotor and thus damaging the product.

[0038] Furthermore, in this embodiment, the downward pressure pin assembly 44 includes a second connecting seat 441; the bottom of the downward pressure rotating seat 42 is also provided with a first limit groove, and the second connecting seat 441 is movably arranged in the first limit groove; the two ends of the bottom of the second connecting seat 441 are respectively connected to a positioning pin 442, and the top of the upper workpiece seat 47 is provided with a first socket extending through its bottom corresponding to the two positioning pins 442; the two positioning pins 442 are respectively movably arranged through a first socket; the top of the second connecting seat 441 is also connected to a first guide rod 443, and the downward pressure rotating seat 42 is also provided with a second socket connected to the first limit groove along its axial direction; the first guide rod 443 is movably inserted into the second socket; the outer wall of the first guide rod 443 is also sleeved with a first spring 444, and the inner wall of the second socket is also provided with a first limit step, and the two ends of the first spring 444 respectively abut against the bottom of the first limit step and the top of the second connecting seat 441.

[0039] When the downward-pressing rotating seat 42 drives the upper workpiece seat 47 to be pressed down, the two positioning pins 442 will hit the rotor. At this time, the positioning pins 442 and the pin holes on the rotor may not be aligned. Therefore, under the influence of the reaction force of the rotor, the positioning pins 442 will move upward. When the positioning pins 442 move upward, they will drive the second connecting seat 441 and the first guide rod 443 to move upward synchronously, and then squeeze the first spring 444 to put it in a compressed state. Subsequently, when performing the pin-finding action, the positioning pins 442 will rotate with the downward-pressing rotating seat 42 until they reach the pin holes of the rotor. At this time, the positioning pins 442 will move downward under the action of the restoring force of the first spring 444 and be inserted into the pin holes, completing the pin-finding and positioning action.

[0040] Furthermore, in this embodiment, the pressing pin assembly 44 also includes a positioning pin 445 and a second spring 446; the lower outer wall of the pressing rotating seat 42 is provided with a first accommodating groove 447, and the bottom of the pressing rotating seat 42 is also provided with a third plug hole connected to the first accommodating groove 447; the upper part of the positioning pin 445 is movably inserted in the third plug hole, and the top of the positioning pin 445 is also connected to the first sensing block 448 arranged in the first accommodating groove 447; the upper outer wall of the positioning pin 445 is provided with a first limiting boss, and the inner wall of the third plug hole is also provided with a second limiting step; the second spring 446 is sleeved on the upper part of the positioning pin 445, and the two ends of the second spring 446 are respectively abutted against the top of the first limiting boss and the bottom of the second limiting step; the top of the upper workpiece seat 47 is also provided with a fourth plug hole that passes through its bottom corresponding to the positioning pin 445, and the lower part of the positioning pin 445 is movably arranged through the fourth plug hole. There is a positioning hole on the rotor. When the pin-finding action is performed, the positioning pin 445 will also rotate with the downward pressing rotating seat 42 until it is inserted into the positioning hole. Its working principle is similar to the above-mentioned pin-finding action and will not be repeated here.

[0041] Furthermore, in this embodiment, the upper portion of the first guide rod 443 is further connected to a first connecting rod 401 in the horizontal direction, and the outer wall of the downward-pressing rotating seat 42 is further provided with two first sliding holes in the vertical direction, and the two first sliding holes are arranged opposite to each other; both ends of the first connecting rod 401 are movably inserted into a first sliding hole; the outer wall of the downward-pressing rotating seat 42 is further movably sleeved with an induction ring 402, and the two end portions of the first connecting rod 401 are connected to the induction ring 402; the lower outer wall of the first bearing seat 461 is further connected to two oppositely arranged first brackets 403, each of which is horizontally mounted with a first proximity switch 404; one of the first proximity switches 404 is arranged on the outside of the induction ring 402, and the other first proximity switch 404 is arranged above the induction ring 402; the lower outer wall of the first bearing seat 461 is further connected to a second bracket 405, and a second proximity switch 406 is further horizontally mounted on the second bracket 405; the second proximity switch 406 is arranged on one side of the first receiving groove 447.

[0042] When the pin is being found, the first guide rod 443 moves up and down synchronously with the positioning pin 442. When the first guide rod 443 moves up and down, the induction ring 402 is driven to move via the first connecting rod 401. At this time, the two first proximity switches 404 detect the signal of the induction ring 402 to determine whether the pin is being found successfully. If the pin is not being found, one of the first proximity switches 404 is located above the induction ring 402, and the other first proximity switch 404 is located on the side of the induction ring 402, so only one proximity switch detects the signal. During operation, when the positioning pin 442 is not inserted into the pin hole, the first guide rod 443 will move upward with the positioning pin 442. At this time, the proximity switch located above the induction ring 402 will also detect a signal, so there are two proximity switches detecting signals. When the positioning pin 442 is inserted into the pin hole, the first guide rod 443 descends. At this time, only one proximity switch detects a signal. Therefore, the staff can use this rule to judge whether the pin-finding action is successful. Similarly, whether the positioning pin 445 is in place can be judged based on whether the second proximity switch 406 detects a signal.

[0043] In one embodiment, a panel 462 is further installed on the top of the downward pressure lifting plate 46; the upper part of the first bearing seat 461 is installed on the panel 462, and the lower part of the first bearing seat 461 is arranged through the downward pressure lifting plate 46; a third bracket 463 is installed on the panel 462, and an encoder 464 is also installed on the bottom of the third bracket 463; the top of the downward pressure rotating seat 42 is connected to the output shaft of the encoder 464 via a coupling 465; the rotary drive mechanism 48 includes a fourth bracket 481 installed on the panel 462, and a rotary motor installed on the fourth bracket 481 482, a driving wheel installed on the output shaft of the rotating motor 482, a driven wheel 483 installed on the upper part of the downward-pressing rotating seat 42, and a transmission belt 484 wound between the driving wheel and the driven wheel 483; a latch base 4621 is also installed on the panel 462, and a translation cylinder 4622 is also installed on the latch base 4621 in the horizontal direction; the output shaft of the translation cylinder 4622 is driven and connected to the first latch; a clamp 4623 is also installed on the upper part of the downward-pressing rotating seat 42, and a clamp hole 4624 is also opened on the outer wall of the clamp 4623 corresponding to the first latch.

[0044] In this embodiment, the top of the pressing rotating seat 42 is connected to the encoder 464, and the encoder 464 can detect the rotation state of the pressing rotating seat 42 in real time, which is convenient for background closed-loop control and improves the rotation accuracy; the rotation drive mechanism 48 adopts a motor in conjunction with a driving wheel, a transmission belt 484 and a driven wheel 483 to ensure the stability of the rotation movement of the pressing rotating seat 42; when the pressing rotating seat 42 drives the rotor to rotate through the positioning pin 442 and returns to the original position, on the one hand, it is to adjust the magnetization position of the rotor, and on the other hand, it is necessary to align the pin hole 4624 on the clamp 4623 with the first pin, and the translation cylinder 4622 drives the first pin to move so that the first pin is inserted into the pin hole 4624, thereby limiting the pressing rotating seat 42 to offset the torque generated during the magnetization of the rotor and avoid the breakage of the transmission belt 484.

[0048] In this embodiment, the first Z-axis lifting mechanism 61 and the first translation mechanism 62 can be made of linear modules. With the cooperation of the two, the detection probe 66 can be driven to perform lifting and translation movements so as to detect the surface magnetic fields of different areas of the rotor. At the same time, in order to improve the detection efficiency, in this embodiment, two groups of detection probes 66 are provided; in addition, the top of the probe mounting frame 65 is slidably connected to the bottom of the probe fixing plate 64, and a buffer spring is provided between the end of the probe mounting frame 65 away from the magnetizing coil and the probe fixing plate 64. When the first translation mechanism 62 drives the detection probe 66 to move excessively toward the rotor and hits the rotor, the buffer spring can buffer the squeezing force on the rotor to avoid damage to the rotor.

The second Z-axis lifting mechanism 72 uses a cylinder transmission method to drive the inspection camera 74 to move up and down, allowing the inspection camera 74 to take photos of different areas of the rotor for inspection.

[0050] In summary, the present invention reduces the footprint of the equipment and reduces the purchase and maintenance costs of the equipment by integrating the magnetization and surface magnetic detection functions. At the same time, the integrated design enables the magnetization and detection processes to be seamlessly connected, reducing the material handling and waiting time in the intermediate links, and further improving production efficiency and economic benefits.
