[0002] With the rapid development of the new energy vehicle industry, the performance and reliability of the motor as one of its core components have received increasing attention. Among the motors for new energy vehicles, permanent magnet synchronous motors have become the mainstream choice due to their high power density, high efficiency, small size and low noise. The motor rotor is a key component of the permanent magnet synchronous motor, and its magnetization process has a vital impact on the overall performance and quality of the motor.

[0003] At present, manual magnetization is still the main method for surface magnetization of motor rotors.

[0019] Continue to refer to Figures 1 to 11As shown, in this embodiment, a workbench is also included, and a workbench 1 is installed on the workbench; in this embodiment, the loading and conveying device 5 includes a loading and conveying frame 51 and a tray lifting mechanism 52; a transmission rail 53 is installed on each side of the top of the loading and conveying frame 51, and a transmission module is also installed on each transmission rail 53; the tray lifting mechanism 52 is arranged between the two transmission rails 53; a stopping mechanism 54 is also installed at one end between the two loading and conveying frames 51.

[0021] During operation, the loading and conveying device 5 receives the product tray carrying the motor rotor transmitted from the upstream transmission line, and transmits it to the predetermined loading position, that is, the position close to the transfer device 4; then, the tray lifting mechanism 52 lifts the product tray from the loading and conveying device 5, and the transfer device 4 clamps the motor rotor on the product tray and transfers it to the lifting device 2 (at this time, the predetermined magnetizing position on the workbench 1 (that is, the lifting device 2) has been pre-placed with a magnetizing coil, and the lifting device 2 passes through the magnetizing coil arrangement); then, the lifting device 2 drives the motor rotor to descend so that the motor rotor is located in the magnetizing coil; then, the clamping device 3 is pressed down to clamp the motor rotor to a limit position and drive it to rotate; finally, the magnetizing coil is energized to magnetize the motor rotor. After the magnetization is completed, the clamping device 3 rises and resets, the lifting device 2 drives the motor rotor to rise, and the transfer device 4 transfers the magnetized motor rotor back to the product tray; then, the tray lifting mechanism 52 places the product tray back on the loading and conveying device 5 and transmits it to the next process.

[0022] In one embodiment, the jacking device 2 includes a jacking drive mechanism 21 installed at the bottom of the workbench 1, a jacking lift plate 22 connected to the jacking drive mechanism 21, a jacking lift seat 23 connected to one side of the jacking lift plate 22, and a jacking lift cylinder 24 installed on the jacking lift seat 23; a first mounting hole is also opened on the workbench 1 at a position corresponding to the jacking lift cylinder 24, and a first guide sleeve 25 is also installed in the first mounting hole; the upper part of the jacking lift cylinder 24 is movably arranged through the first guide sleeve 25; a lower fixture seat 26 is also installed on the top of the jacking lift cylinder 24, and an upper fixture seat 27 is also installed on the top of the lower fixture seat 26; the upper fixture seat 27 and the lower fixture seat 26 are both axially hollow structures, and the axially hollow part of the upper fixture seat 27 and the axially hollow part of the lower fixture seat 26 are arranged in alignment with each other; a rotating bearing component 28 for bearing products is also installed in the lower fixture seat 26.

[0023] In this embodiment, the jacking drive mechanism 21 includes a jacking mounting frame connected to the bottom of the workbench 1, and a jacking drive component installed on the jacking mounting frame; the jacking drive component adopts a transmission method of a motor and a screw, and the jacking lifting plate 22 is slidably connected to one side of the jacking mounting frame through a slide rail and a slider; the jacking drive component can drive the jacking lifting seat 23 to drive the jacking lifting cylinder 24 to rise and fall relative to the first guide sleeve 25, and the top of the jacking lifting cylinder 24 is successively installed with a lower fixture seat 26 and an upper fixture seat 27, and the motor rotor is placed on the upper fixture seat 27, so it can drive the motor rotor to perform synchronous lifting and lowering movements; at the same time, a first fixing ring is also installed on the lower outer wall of the first guide sleeve 25, and a stop rod is also installed on the first fixing ring, which can limit the lifting and lowering stroke of the jacking lifting cylinder 24 to improve its operation safety.

[0024] In addition, the rotating bearing assembly 28 includes a rotating bearing column 281, a first deep groove ball bearing 282 installed in the lower part of the lower fixture seat 26, and a thrust ball bearing, a first washer 358, and a second deep groove ball bearing 283 installed in the upper part of the lower fixture seat 26 from top to bottom; the lower part of the rotating bearing column 281 is connected to the first deep groove ball bearing 282, and the upper part of the rotating bearing column 281 passes through the second deep groove ball bearing 283, the first washer 358 and the thrust ball bearing arrangement in sequence; the upper part of the rotating bearing column 281 is also provided with a first limiting step 284, and the first limiting step 284 is arranged on the thrust ball bearing. When the motor rotor is transferred to the upper jig seat 27 by the transfer device 4, its lower shaft passes through the upper jig seat 27, is inserted into the lower jig seat 26 and placed on the rotating bearing column 281. The rotating bearing column 281 can support the motor rotor. At the same time, the rotating bearing column 281 is installed in the lower jig seat 26 through multiple bearings and can rotate relative to the lower jig seat 26, so that the clamping device 3 drives the motor rotor to rotate, thereby facilitating its magnetization.

[0025] In one embodiment, the lifting device 2 further includes a positioning pin assembly 29; the positioning pin assembly 29 includes a spring guide rod 291; a bearing mounting block 292 is installed at the upper portion of the lifting and lifting cylinder 24, and a first linear bearing is also installed in the bearing mounting block 292; the spring guide rod 291 is movably arranged in the lifting and lifting cylinder 24, and the upper portion of the spring guide rod 291 passes through the first linear bearing arrangement; the top of the spring guide rod 291 is also connected to a first support bar 293, and the top ends of the first support bar 293 are each connected A positioning pin 294; the top of the lower fixture seat 26 is also provided with two first sockets extending to the bottom thereof, and the two positioning pins 294 are respectively movable through a first socket arrangement; a positioning hole 295 is also provided at the bottom of the upper fixture seat 27 corresponding to the positioning pin 294; a second limiting step is also provided in the jacking lifting cylinder 24; the outer wall of the spring guide rod 291 is sleeved with a first spring 296, and the two ends of the first spring 296 are respectively abutted against the bottom of the first support bar 293 and the top of the second limiting step.

[0026] The spring guide rod 291 can move up and down relative to the lifting cylinder 24. When replacing different types of upper fixture seats 27, it is necessary to first perform a pin-finding and positioning action, because at this time the positioning socket 295 at the bottom of the upper fixture seat 27 may not be aligned with the positioning pin 294, which will then generate downward pressure on the positioning pin 294, causing the positioning pin 294 to move downward. When the positioning pin 294 moves downward, a downward force is applied to the spring guide rod 291 through the first support bar 293, causing the spring guide rod 291 to move downward as well. When the spring guide rod 291 moves downward, it squeezes the first spring 296. The pressure causes the first spring 296 to be in a compressed state, and under the influence of the restoring force of the first spring 296, the spring guide rod 291 will generate a continuous upward restoring force on the positioning pin 294. At this time, the upper fixture seat 27 is rotated until the positioning pin 294 is aligned with the positioning socket 295. The positioning pin 294 is driven by the restoring force of the first spring 296 to move upward and then inserted into the positioning socket 295, completing the rapid positioning of the upper fixture seat 27. The flexible pin-finding positioning method in which the positioning pin 294 first descends and then rises can be used to realize rapid replacement of the fixture and at the same time, it can also prevent the pin from damaging the fixture.

[0027] In addition, a second linear bearing is also installed at the bottom of the lifting and lifting seat 23, and the lower part of the spring guide rod 291 passes through the second linear bearing after passing through the lifting and lifting cylinder 24; a detection mounting plate is connected to each side of the lifting and lifting seat 23, and a first proximity switch 297 is installed on each detection mounting plate; the bottom of the spring guide rod 291 is also connected to an induction coil 298, and the induction coil 298 is located between the two first proximity switches 297; the part of the spring guide rod 291 located in the lifting and lifting cylinder 24 is also installed with a first stopper, and the outer wall of the first stopper is also connected to a first stopper 299; the outer wall of the lifting and lifting cylinder 24 is also provided with a limiting sliding hole along its axial direction, and one end of the first stopper 299 is arranged through the limiting sliding hole. Through the cooperation between the induction coil 298 and the first proximity switch 297, the position of the spring guide rod 291 can be detected, which is convenient for accurately controlling the pin-finding action. At the same time, one end of the first baffle 299 is arranged through the limit sliding hole, which can guide the spring guide rod 291 when it is raised or lowered, so as to ensure the stability of its lifting and lowering. In addition, the outer wall of the lower fixture seat 26 is also installed with a detection strip 261, and a plurality of detection holes are spaced apart in the vertical direction on one side of the detection strip 261. Induction sheets can be installed in the detection holes at different positions, and different arrangements and combinations (multiple detection switches are installed near the detection holes of the equipment, each detection switch corresponds to a detection hole, and different detection signals of the detection switches are used to determine whether the tooling matches. For example, it is pre-set that only one detection switch detects a signal, which corresponds to one product, and two detection switches detect a signal, which corresponds to another product. Through different arrangements and combinations, multiple types of tooling can be quickly detected).
