[0002] With the widespread use of electric motors, the requirements for component assembly during motor production are becoming increasingly stringent. The rotor, a key component of a motor, often requires a magnetic ring to be press-fitted onto its central axis.

The transverse movement mechanism 600 is located in front of the magnetic testing device 200 and the magnetic ring clamping device 300. The rotor inspection device 400 is mounted on the machine platform 100 and located in front of the robot 500. Among them, the rotor is automatically grabbed by the manipulator 500 and placed on the rotor detection device 400; the rotor that has passed the inspection of the rotor detection device 400 is grabbed by the manipulator 500 and moved to the magnetic detection platform 240; the magnetic detection platform 240 driven by the lifting mechanism 230 first drives the rotor to the magnetic flux measuring position, and completes the magnetic flux detection of the rotor through the magnetic flux testing mechanism 210; the magnetic detection platform 240 then drives the rotor down to the surface magnetic position, and completes the surface magnetic quantity detection of the rotor through the surface magnetic testing mechanism 220; the rotor that has passed the inspection of the magnetic testing device 200 is grabbed from the magnetic detection platform 240 by the transverse movement mechanism 600 and placed on the pressure ring loading platform 320, and the pressing mechanism 310 presses the magnetic ring downward to fit it on the rotor.

[0028] Based on this design, in this embodiment, since the magnetic testing device 200, the magnetic ring pressing device 300 and the rotor detection device 400 are provided on the same machine 100, and the rotor can be automatically loaded and unloaded in the aforementioned devices through the conveying device, the machine for rotor magnetic testing and magnetic ring pressing can integrate multiple process flows such as rotor detection, rotor magnetic testing and pressing the magnetic ring on the rotor into a complete set of process flows, reducing the turnover process, saving production space, and greatly improving production detection efficiency.

[0029] See also Figure 1 and Figure 8In the embodiment, the angle of the rotor is detected before the magnetic detection of the rotor. Specifically, the rotor detection device 400 comprises a detection frame 410, a detection platform 420, a detection camera 430 and a detection position sensor 440; the detection platform 420 is connected to the upper end of the detection frame 410; the detection camera 430 is arranged below the detection platform 420 and is used to shoot the lower surface of the detection rotor; the detection position sensor 440 is located beside the detection platform 420 and is higher than the detection platform 420, so that the detection position sensor 440 can check whether the rotor has arrived on the detection platform 420. The magnetic steel in the rotor is staggered at a certain angle for each layer, and the lower end of the rotor is marked with a mark groove, the left side of which is the positive electrode and the right side is the negative electrode. The detection camera 430 is fixed below the detection platform 420 by a sheet metal part, when the robot 500 places the rotor on the detection platform 420, the detection camera 430 will shoot the lower surface of the rotor and transmit the detection image to the corresponding control system such as a detection host and the like, and then the detection host calculates and judges whether the angle of the rotor is qualified according to the obtained detection image by using relevant image phase algorithm and the like, if qualified, the next step of magnetic flux detection is performed; if not qualified, the rotor needs to be adjusted to the predetermined position, and then the magnetic flux detection is performed after the detection is qualified.

[0030] Please refer to Figure 1 and Figure 10 In the embodiment, the robot 500 comprises a motion arm 510 and a clamping jaw assembly 520 arranged at the free end of the motion arm 510, the clamping jaw assembly 520 comprises a clamping jaw connecting plate 521, a clamping jaw cylinder 522 and a rotating air jaw 523; the clamping jaw cylinder 522 is detachably connected with the motion arm 510 through the clamping jaw connecting plate 521, and the clamping jaw cylinder 522 drives the rotating air jaw 523 to realize 360-degree axial rotation. Here, the robot 500 is specifically a four-axis robot 500, and the rotating air jaw 523 which can rotate 360 degrees facilitates the adjustment of the angle of the rotor. In addition, the part of the inner side of the rotating air jaw 523 which contacts the outer side of the rotor is preferably provided with a super glue 524 to enhance the friction of the inner side of the rotating air jaw 523, so that the rotating air jaw 523 can more tightly grasp the rotor.

[0031] Please refer to Figure 1 , Figure 4 and Figure 5In this embodiment, the lifting mechanism 230 includes a lifting motor 231, a main synchronous wheel 232, a plurality of sub-synchronous wheels 233, a synchronous belt 234, a lifting base plate 235, a base plate connecting plate 236 and a plurality of screw rods 237; the lifting base plate 235 is located below the magnetic detection platform 240 and is transmission-connected to the magnetic detection platform 240 through a plurality of spaced screw rods 237; one end of the base plate connecting plate 236 is connected to the lifting base plate 235, and the other end of the base plate connecting plate 236 extends out of the lifting base plate 235 and is installed with a lifting motor 231; the main synchronous wheel 232 is provided on the bottom surface of the base plate connecting plate 236 and is connected to the rotating shaft of the lifting motor 231, and a plurality of sub-synchronous wheels 233 are spaced on the bottom surface of the lifting base plate 235 and are transmission-connected to the screw rods 237 at corresponding positions respectively; the main synchronous wheel 232 and the sub-synchronous wheel 233 are both transmission-connected by a synchronous belt 234 to achieve synchronous rotation. Specifically, in this embodiment, there is one main synchronous wheel 232 and two auxiliary synchronous wheels 233. The main synchronous wheels 232 and the two auxiliary synchronous wheels 233 are arranged in a triangular shape. The lifting motor 231 is mounted on the bottom plate connecting plate 236 and is located above the main synchronous wheel 232. This arrangement not only ensures that the lifting motor 231 drives and controls the main synchronous wheel 232, but also makes the overall structure more integrated and compact, which is more conducive to accurately controlling the lifting accuracy of the magnetic detection platform 240, thereby improving the accuracy of magnetic detection. After the lifting motor 231 is started, it will drive the main synchronous wheel 232 to rotate. Then, the main synchronous wheel 232 drives the two auxiliary synchronous wheels 233 to rotate synchronously via the synchronous belt 234. The two auxiliary synchronous wheels 233 then drive the two corresponding screw rods 237 connected thereto to rotate, thereby achieving the lifting and lowering of the magnetic detection platform 240. However, the present design is not limited to this. In other embodiments, the lifting and lowering of the magnetic detection platform 240 can also be achieved through other structural designs. However, in this embodiment, the lifting mechanism 230 design of the motor, synchronous wheel, synchronous belt 234 and screw rod 237 can make the lifting and lowering of the magnetic detection platform 240 more stable and accurate, which is beneficial to improving the accuracy of magnetic detection of the rotor.

[0032] Furthermore, if Figure 4 and Figure 5As shown, in this embodiment, the magnetic testing device 200 also includes a rotating mechanism 250, which includes a rotating motor 251, a rotating coupling 252 and a rotating bracket 253; the rotating bracket 253 is arranged below the magnetic detection platform 240 and is located in the space surrounded by multiple screw rods 237; the upper end of the rotating bracket 253 is fixedly connected to the lower surface of the magnetic detection platform 240, and the rotating motor 251 is installed on the lower surface of the rotating bracket 253; the lower end of the rotating coupling 252 is connected to the rotating motor 251, and the upper end of the rotating coupling 252 passes through the through hole of the magnetic detection platform 240 and is exposed on the magnetic detection platform 240; after the rotor is placed on the magnetic detection platform 240, it is positioned and connected to the upper end of the rotating coupling 252. Here, the rotating bracket 253 is arranged below the magnetic detection platform 240 and is located in the space surrounded by multiple screw rods 237. This allows the lifting mechanism 230 and the rotating mechanism 250 to be integrated into one, making the structure more compact and reducing the production space occupied by the components. The provision of the rotating coupling 252 can make the rotor rotation more stable. In addition, multiple magnetic positioning bosses 241 are fixed to the magnetic detection platform 240, stacked from bottom to top, so as to be suitable for the positioning and placement of rotors of different models and sizes on the magnetic detection platform 240. The center of the magnetic positioning boss 241 protrudes with a rotating shaft 242 that drives the rotor to rotate. The rotating shaft of the rotating motor 251 passes through the rotating coupling 252 and is connected to the rotating shaft 242. During actual operation, the rotating mechanism 250 and the lifting mechanism 230 cooperate to realize the rotational lifting movement of the rotor on the magnetic detection platform 240. In addition, when the rotor rises and is located in the magnetic flux measuring position, the rotating mechanism 250 can also drive the rotor to rotate axially in the flux meter 212, thereby completing the magnetic flux test. Similarly, when the rotor is located in the surface magnetic measuring position, the rotating mechanism 250 can also drive the rotor to rotate, thereby completing the surface magnetic test.

[0033] See also Figures 1 to 3In this embodiment, the magnetic flux testing mechanism 210 includes a magnetic flux detection bracket 211, a fluxmeter 212, and a positioning pin assembly. The magnetic flux detection bracket 211 includes a first mounting plate 211a, a second mounting plate 211b, a fluxmeter connecting plate 211c, and a plurality of mounting posts 211d. The first mounting plate 211a is located parallel to and above the second mounting plate 211b. The lower ends of the mounting posts 211d are fixedly connected to the machine 100. The upper ends of the mounting posts 211d pass through the second mounting plate 211b and are fixedly connected to the first mounting plate 211a. The second mounting plate 211b is also fixedly connected to the mounting posts 211d. The rear end of the fluxmeter connecting plate 211c is fixedly connected to the first mounting plate 211a. The fluxmeter 212 is mounted on the bottom surface of the fluxmeter connecting plate 211c, which protrudes from the second mounting plate 211b. In addition, to facilitate the installation of the flux meter 212 and ensure that both the magnetic flux and the surface magnetism can be measured when the rotor moves up and down along the axial direction, a avoidance groove 211e is provided at the front end of the second mounting plate 211b for the rear end of the flux meter 212 to extend into. Specifically, the positioning ejector assembly includes a positioning ejector 213, an ejector slide rail 214, an ejector slider 215 and an ejector connector 216; the axial direction of the positioning ejector 213 is the up and down direction, and the slide plate provided with the ejector slide rail 214 is vertically installed on the first mounting plate 211a, the ejector slider 215 is slidably connected to the ejector slide rail 214, and the upper end of the positioning ejector 213 is connected to the ejector slider 215 through the ejector connector 216, and the ejector slider 215 is driven to slide up and down on the ejector slide rail 214 to drive the positioning ejector 213 to move up and down; the lower end of the positioning ejector 213 is provided with a conical positioning protrusion 217, and the upper end of the central axis of the rotor is provided with a positioning recess adapted to the shape of the positioning protrusion 217. When the rotor is lifted to the magnetic flux measurement position by the lifting mechanism 230 and the rotating mechanism 250, the positioning pin 213 moves downward until the positioning protrusion 217 aligns and abuts the positioning recess, achieving coaxial positioning of the rotor and positioning pin 213. During actual operation, when the rotor is in the magnetic flux measurement position, the control system controls the driver to drive the pin slide 215 downward on the pin rail 214 until the positioning protrusion 217 of the positioning pin 213 abuts the positioning recess at the upper end of the rotor's central axis. In this way, the rotor is positioned by the positioning pin 213, preventing the rotor from swinging during magnetic flux and surface magnetism measurements, thereby ensuring the accuracy of the magnetic test. When the rotor magnetic test is completed and the rotor stops rotating, the control system controls the driver to drive the pin slide 215 upward on the pin rail 214 to disengage the positioning pin 213 from the rotor.

[0034] See also Figures 1 to 3In this embodiment, the surface magnetic field measuring position is located below the magnetic flux measuring position, and the surface magnetic testing mechanism 220 is located behind the surface magnetic field measuring position. It includes a surface magnetic detection connecting plate 221, a surface magnetic detection driver 222, and a surface magnetic probe 223. The surface magnetic detection driver 222 is mounted on the second mounting plate 211b via the surface magnetic detection connecting plate 221. The surface magnetic probe 223 is driven by the surface magnetic detection driver 222 to achieve back and forth movement. After the rotor reaches the surface magnetic field measuring position, the surface magnetic probe 223 moves forward to approach the outer side of the rotor. The rotating mechanism 250 drives the rotor to rotate one revolution, allowing the surface magnetic probe 223 to complete the surface magnetic test. Here, the arrangement of a fluxmeter 212 fixed to the first mounting plate 211a and a surface magnetic probe 223 fixed to the second mounting plate 211b allows two rotor magnetic tests to be performed simultaneously on the same magnetic testing platform 420, effectively improving testing efficiency. Furthermore, the first mounting plate 211a and the second mounting plate 211b are parallel and spaced apart, and their relative positions are adjustable, thereby accommodating the testing of rotors of varying specifications and effectively expanding the scope of testing. In this embodiment, the surface magnetic detection driver 222 is specifically a cylinder. Of course, in other embodiments, the surface magnetic detection driver 222 may also be, but is not limited to, a motor. During actual operation, when the rotor drops from the magnetic flux measuring position to the surface magnetic measuring position, first, the position sensor at the rear is used to determine that the rotor is in the correct surface magnetic measuring position; then, the control system controls the surface magnetic detection driver 222 to start, so that the surface magnetic detection driver 222 drives the surface magnetic probe 223 to move forward until the front end of the surface magnetic probe 223 is 1 to 2 mm away from the outer side of the rotor, and then, the rotating mechanism 250 drives the rotor to rotate one circle, and the surface magnetic probe 223 completes the surface magnetic test of the rotor; after the surface magnetic test is completed, the surface magnetic detection driver 222 drives the surface magnetic probe 223 to move backward to move away from the rotor, and the rotor then drops to the position for loading before magnetic measurement.

[0035] See also Figure 1 and Figure 9In this embodiment, a transverse movement mechanism 600 is required to realize the movement of the rotor between the magnetic testing device 200 and the magnetic ring pressing device 300 and automatic loading and unloading. Specifically, the transverse mechanism 600 includes a transverse slide rail 610, a transverse connection assembly 620, a transverse gripper assembly 630, a first drive member, a second drive member 650 and a third drive member 660; the transverse slide rail 610 is in the shape of a long strip, and the length direction of the transverse slide rail 610 is the left and right direction; one end of the transverse connection assembly 620 is slidingly connected to the transverse slide rail 610, and the other end of the transverse connection assembly 620 is connected to the transverse gripper assembly 630; the first drive member is arranged under the transverse slide rail 610, and drives the transverse connection assembly 620 to move left and right along the transverse slide rail 610; the second drive member 650 is arranged on the transverse connection assembly 620, and drives the transverse gripper assembly 630 to move up and down; the third drive member 660 is arranged on the transverse connection assembly 620, and drives the second drive member 650 and the transverse gripper assembly 630 to move forward and backward together. The transverse gripper assembly 630 includes a transverse gripper driver 631 and a transverse clamping jaw 632. The transverse gripper driver 631 is connected to the transverse connection assembly 620 and drives the V-shaped transverse clamping jaw 632 to open and close. Here, the first, second, and third drivers 650, 660 are all pneumatic cylinders. However, in other embodiments, they may also be, but are not limited to, drive motors. During the actual operation, the first driving member drives the transverse gripper assembly 630 to move to the front of the magnetic detection platform 240, and the transverse gripper driving member 631 drives the V-shaped transverse clamp 632 to open and close to clamp the upper part of the central axis of the rotor. The first driving member drives the transverse gripper assembly 630 to move horizontally to the front of the pressure ring loading platform 320. Then, the third driving member 660 drives the transverse gripper assembly 630 to move forward to the pressure ring loading platform 320. After that, the transverse gripper driving member 631 drives the transverse clamp 632 to open so that the rotor is placed on the pressure ring loading platform 320. After the rotor is pressed and fitted with the magnetic ring, the transverse gripper driver 631 drives the transverse clamp 632 to open and close to grab the rotor. Then, the first driver drives the transverse gripper assembly 630 to move to the front of the transfer platform at the intermediate transfer position next to the pressure ring loading platform 320. Then, the third driver 660 drives the transverse gripper assembly 630 to move forward to the transfer platform at the intermediate transfer position. The transverse gripper driver 631 drives the transverse clamp 632 to open so that the rotor is placed on the transfer platform at the intermediate transfer position. Finally, the rotor with the magnetic ring pressed and fitted will be moved to the next assembly process flow at the intermediate transfer position. In addition, since the heights of the magnetic detection platform 240, the pressure ring loading platform 320 and the intermediate transfer position loading platform may be inconsistent, the transverse gripper assembly 630 can also be moved up and down by the second driver 650, thereby achieving height adjustment of the transverse gripper assembly 630.

The press position sensor 325 is located behind the press positioning boss 326. After the rotor's magnetic properties are measured, the rotor will be grasped by the transverse movement mechanism 600 and placed on the press positioning boss 326 of the pressure ring loading platform 320. During placement, the press positioning member 324 inserts into the bottom of the rotor to achieve the function of positioning the rotor. After the rotor is placed, the position sensor behind it will detect that the rotor is in the press-fitting position and send a relevant signal to the control system. Then, the control system controls the press-fitting mechanism 310 to complete the press-fitting of the magnetic ring.

[0037] See also Figure 1 and Figure 6 In this embodiment, the press-fitting mechanism 310 includes a press-fitting bracket 311, a press cylinder assembly, and a pressure sensor. The press-fitting bracket 311 is fixed to the machine platform 100. The press cylinder assembly includes a press cylinder 312 and a press head 313. The press cylinder 312 is fixed to the top plate of the press-fitting bracket 311, and the upper end of the press head 313 is in transmission connection with the press cylinder 312. The pressure sensor is provided on the press head 313. The magnetic ring is pre-mounted on the upper end of the central shaft of the rotor, which is positioned on the press-fitting positioning boss 326. The press head 313 is driven downward by the press cylinder 312, pressing the magnetic ring downward and fixing it on the upper end step of the central shaft of the rotor. Here, during the press-fitting process of the magnetic ring, the sudden pressure change detected by the pressure sensor can be used to determine whether the magnetic ring has been press-fitted into place. In addition, an upper and lower axial ejector pin is provided inside the pressing head 313, the upper end of the ejector pin is sleeved with a spring, and the lower end of the ejector pin is also provided with a conical protrusion, which can cooperate with the positioning recess at the upper end of the central axis of the rotor, thereby realizing the axial alignment positioning of the rotor when the magnetic ring is pressed. In this way, the rotor is not easily displaced or swung during press-fitting, so that the press-fitting position of the magnetic ring is accurate and the process is smooth.
