Description

Technical Field

[0001] This application belongs to the technical field of motor component manufacturing equipment, and more specifically, relates to a machine for rotor magnetic testing and magnetic ring clamping. Background Technology

[0002] With the widespread application of electric motors, the requirements for component assembly in the motor manufacturing process are becoming increasingly stringent. As one of the main components of an electric motor, the rotor often requires the pressing of a magnetic ring onto its central shaft. Before pressing the magnetic ring, the rotor's performance, especially its critical magnetic properties, needs to be tested to ensure that only rotors meeting performance standards can be fitted with the magnetic ring.

[0003] However, in current common rotor manufacturing processes, magnetic ring assembly uses one set of equipment and processes, while rotor magnetic testing, such as magnetic flux detection and surface magnetic field testing, uses separate testing equipment and processes. These processes require manual loading and unloading of materials and material handling, resulting in low testing and assembly efficiency. Summary of the Invention

[0050] This application provides a machine for rotor magnetic testing and magnetic ring clamping.

[0051] Please see Figures 1 to 10In one embodiment, the machine for rotor magnetic testing and magnetic ring clamping includes a machine base 100, a magnetic testing device 200, a magnetic ring clamping device 300, a conveying device, and a rotor detection device 400. Specifically, the magnetic testing device 200 is mounted on the machine base 100 and includes a flux testing mechanism 210, a surface magnetic testing mechanism 220, a lifting mechanism 230, and a magnetic detection platform 240 located below the flux testing mechanism 210; the magnetic testing device 200 has a flux measurement position and a surface magnetic measurement position. The magnetic ring clamping device 300 is mounted on the machine base 100 and located beside the magnetic testing device 200; the magnetic ring clamping device 300 includes a pressing mechanism 310 and a ring loading platform 320 located below the pressing mechanism 310. The conveying device is mounted on the machine base 100 and includes a robot arm 500 and a transverse mechanism 600. The robot arm 500 is located on the side of the magnetic testing device 200 away from the magnetic ring clamping device 300, and the transverse mechanism 600 is located in front of the magnetic testing device 200 and the magnetic ring clamping device 300. The rotor detection device 400 is mounted on the machine base 100 and located in front of the robot arm 500. The rotor is automatically picked up by a robotic arm 500 and placed on a rotor testing device 400. After passing the test by the rotor testing device 400, the rotor is picked up by the robotic arm 500 and moved to a magnetic testing platform 240. Driven by a lifting mechanism 230, the magnetic testing platform 240 first raises the rotor to the magnetic flux measurement position, and the magnetic flux of the rotor is tested by a magnetic flux testing mechanism 210. The magnetic testing platform 240 then lowers the rotor to the magnetic meter measurement position, and the magnetic meter measurement of the rotor is tested by a magnetic meter measurement mechanism 220. After passing the test by the magnetic testing device 200, the rotor is picked up from the magnetic testing platform 240 by a horizontal moving mechanism 600 and placed on a pressure ring loading platform 320. The pressing mechanism 310 presses the magnetic ring downwards to fit onto the rotor.

[0052] Based on this design, in this embodiment, since the magnetic testing device 200, the magnetic ring pressing device 300, and the rotor testing device 400 are set on the same machine 100, and the rotor can be automatically loaded and unloaded in the aforementioned devices through the conveying device, the machine used for rotor magnetic testing and magnetic ring pressing can integrate multiple processes such as rotor testing, rotor magnetic testing, and pressing the magnetic ring onto the rotor into a complete process, reducing the turnover process, saving production space, and greatly improving production and testing efficiency.

[0053] Please see Figure 1 and Figure 8In this embodiment, the rotor angle needs to be detected before performing magnetic detection on the rotor. Specifically, the rotor detection device 400 includes 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 located below the detection platform 420 and is used to photograph the lower surface of the rotor. The detection position sensor 440 is located beside the detection platform 420 and is higher than the detection platform 420. Thus, the detection position sensor 440 can be used to check and determine whether the rotor has reached the detection platform 420. The magnets inside the rotor are staggered at a certain angle in each layer. The lower end of the rotor is engraved with marking grooves, with the left side of the marking groove being the positive pole and the right side being the negative pole. A detection camera 430 is fixed below the detection platform 420 by sheet metal parts. When the robot arm 500 places the rotor on the detection platform 420, the detection camera 430 will take a picture of the lower surface of the rotor and transmit the detection image to the corresponding control system, such as the detection host. Then, the detection host uses relevant image phase algorithms to calculate and determine whether the angle of the rotor is qualified based on the obtained detection image. If it is qualified, the next step of magnetic flux detection is carried out; if it is not qualified, the rotor needs to be adjusted to the predetermined position and then the detection is carried out. Only after it is qualified can the magnetic flux detection be carried out.

[0054] Please see Figure 1 and Figure 10 In this embodiment, the robotic arm 500 includes a motion arm 510 and a gripper assembly 520 disposed at the free end of the motion arm 510. The gripper assembly 520 includes a gripper connecting plate 521, a gripper cylinder 522, and a rotary gripper 523. The gripper cylinder 522 is detachably connected to the motion arm 510 through the gripper connecting plate 521, and the gripper cylinder 522 drives the rotary gripper 523 to achieve 360-degree axial rotation. Here, the robotic arm 500 is specifically a four-axis robotic arm 500, and the 360-degree rotatable rotary gripper 523 facilitates adjustment of the rotor angle. In addition, the inner side of the rotary gripper 523, the part in contact with the outer side of the rotor, is preferably provided with urethane rubber 524 to enhance the inner friction of the rotary gripper 523, so that the rotary gripper 523 grips the rotor more tightly.

[0055] Please see Figure 1 , Figure 4 and Figure 5In this embodiment, the lifting mechanism 230 includes a lifting motor 231, a main synchronous pulley 232, multiple auxiliary synchronous pulleys 233, a synchronous belt 234, a lifting base plate 235, a base plate connecting plate 236, and multiple lead screws 237. The lifting base plate 235 is located below the magnetic detection platform 240 and is connected to the magnetic detection platform 240 via multiple spaced lead screws 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 equipped with the lifting motor 231. The main synchronous pulley 232 is located on the bottom surface of the base plate connecting plate 236 and is connected to the rotating shaft of the lifting motor 231. Multiple auxiliary synchronous pulleys 233 are spaced apart on the bottom surface of the lifting base plate 235 and are respectively connected to the lead screws 237 at their corresponding positions. The main synchronous pulley 232 and the auxiliary synchronous pulleys 233 are both connected via the synchronous belt 234 to achieve synchronous rotation. Specifically, in this embodiment, there is one main synchronous pulley 232 and two auxiliary synchronous pulleys 233, arranged in a triangular pattern. The lifting motor 231 is mounted on the base plate connecting plate 236 and positioned above the main synchronous pulley 232. This arrangement ensures the driving control of the lifting motor 231 over the main synchronous pulley 232, and also makes the overall structure more integrated and compact. This facilitates precise control of the lifting accuracy of the magnetic detection stage 240, thereby improving the accuracy of magnetic detection. After the lifting motor 231 starts, it drives the main synchronous pulley 232 to rotate. Then, the main synchronous pulley 232 drives the two auxiliary synchronous pulleys 233 to rotate synchronously via the synchronous belt 234. The two auxiliary synchronous pulleys 233 then drive the two corresponding lead screws 237 connected to them to rotate, thereby realizing the lifting of the magnetic detection stage 240. However, this design is not limited to this. In other embodiments, the lifting and lowering of the magnetic detection stage 240 can also be achieved through other structural designs. However, in this embodiment, the design of the lifting mechanism 230 with motor, synchronous pulley, synchronous belt 234 and lead screw 237 can make the lifting and lowering of the magnetic detection stage 240 more stable and precise, thereby improving the accuracy of magnetic detection of the rotor.

[0056] Furthermore, such as Figure 4 and Figure 5As shown, in this embodiment, the magnetic testing device 200 further 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 located below the magnetic testing platform 240 and within the space enclosed by multiple lead screws 237. The upper end of the rotating bracket 253 is fixedly connected to the lower surface of the magnetic testing platform 240, and the rotating motor 251 is mounted 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 testing platform 240 and is exposed on the magnetic testing platform 240. After the rotor is placed on the magnetic testing platform 240, it is positioned and connected to the upper end of the rotating coupling 252. Here, the rotating bracket 253 is located below the magnetic testing platform 240 and within the space enclosed by multiple lead screws 237, allowing the lifting mechanism 230 and the rotating mechanism 250 to be integrated into one unit, resulting in a more compact structure and reduced production space occupied by components. The rotating coupling 252 further stabilizes the rotor rotation. Additionally, multiple magnetic positioning bosses 241, stacked from bottom to top, are fixed on the magnetic testing platform 240, accommodating the positioning of rotors of different sizes. A rotating shaft 242, which drives the rotor's rotation, protrudes from the center of each magnetic positioning boss 241. The rotating shaft of the rotary motor 251 passes through the rotating coupling 252 and connects to the rotating shaft 242. In actual operation, the rotating mechanism 250 and the lifting mechanism 230 work together to achieve the rotating and lifting motion of the rotor on the magnetic testing platform 240. In addition, when the rotor rises to the flux measurement position, the rotating mechanism 250 can also drive the rotor to rotate axially within the flux meter 212, thereby completing the flux measurement. Similarly, when the rotor is in the meter magnetic position, the rotating mechanism 250 can also drive the rotor to rotate, thereby completing the meter magnetic test.

[0057] Please see 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 parallel to and above the second mounting plate 211b. The lower end of the mounting post 211d is fixedly connected to the machine base 100, and the upper end of the mounting post 211d passes through the second mounting plate 211b and is fixedly connected to the first mounting plate 211a. The second mounting plate 211b is also fixedly connected to the mounting post 211d. The rear end of the fluxmeter connecting plate 211c is fixedly connected to the first mounting plate 211a, and the fluxmeter 212 is mounted on the bottom surface of the fluxmeter connecting plate 211c in the area protruding from the second mounting plate 211b. In addition, to facilitate the installation of the flux meter 212 and to ensure that both the magnetic flux measurement and the meter magnetic field measurement can be completed when the rotor moves up and down along the axial direction, a clearance 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 vertical. The slide plate with the ejector slide rail 214 is vertically mounted on the first mounting plate 211a. The ejector slider 215 is slidably connected to the ejector slide rail 214. The upper end of the positioning ejector 213 is connected to the ejector slider 215 through the ejector connector 216. 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 tapered positioning protrusion 217. The upper end of the central shaft of the rotor is provided with a positioning recess that matches the shape of the positioning protrusion 217. After the rotor is lifted to the 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 against the positioning recess, achieving coaxial positioning of the rotor and the positioning pin 213. During actual operation, when the rotor is at the flux measurement position, the control system controls the drive component to drive the pin slider 215 downward on the pin slide rail 214 until the positioning protrusion 217 of the positioning pin 213 abuts against the positioning recess at the upper end of the rotor's central shaft. This allows the rotor to be positioned using the positioning pin 213, preventing it from wobbling during flux and magnetism measurements, thus ensuring the accuracy of the magnetic test. After the rotor magnetic test is completed and the rotor stops rotating, the control system controls the drive component to drive the pin slider 215 upward on the pin slide rail 214, disengaging the positioning pin 213 from the rotor.

[0058] Please see Figures 1 to 3In this embodiment, the magnetic flux measurement position is located below the magnetic flux measurement position, and the magnetic flux measurement mechanism 220 is located behind the magnetic flux measurement position. It includes a magnetic flux detection connecting plate 221, a magnetic flux detection drive 222, and a magnetic flux probe 223. The magnetic flux detection drive 222 is mounted on the second mounting plate 211b via the magnetic flux detection connecting plate 221. The magnetic flux probe 223 is driven by the magnetic flux detection drive 222 to move back and forth. After the rotor is positioned at the magnetic flux measurement position, the magnetic flux probe 223 moves forward towards the outer side of the rotor. The rotating mechanism 250 drives the rotor to rotate one revolution, allowing the magnetic flux probe 223 to complete the magnetic flux measurement. Here, the arrangement of fixing a fluxmeter 212 on the first mounting plate 211a and a surface magnetic probe 223 on the second mounting plate 211b allows the rotor to complete two magnetic tests simultaneously on the same magnetic detection platform 420, effectively improving detection efficiency. Furthermore, the parallel spacing and adjustable relative positions of the first and second mounting plates 211a and 211b allow for testing rotors of different specifications, effectively expanding the scope of application. In this embodiment, the surface magnetic detection drive 222 is specifically a cylinder; however, in other embodiments, the surface magnetic detection drive 222 can also be, but is not limited to, a motor. In actual operation, after the rotor descends from the flux measurement position to the magnetic field measurement position, firstly, the position sensor at the rear confirms that the rotor is in the correct magnetic field measurement position; then, the control system controls the magnetic field detection drive 222 to start, causing the magnetic field detection drive 222 to drive the magnetic field probe 223 forward until the front end of the magnetic field probe 223 is 1 to 2 mm away from the outer side of the rotor. Then, the rotating mechanism 250 drives the rotor to rotate one revolution, and the magnetic field probe 223 completes the magnetic field test of the rotor; after the magnetic field test is completed, the magnetic field detection drive 222 drives the magnetic field probe 223 to move backward away from the rotor, and the rotor then descends to the loading position before magnetic field measurement.

[0059] Please see Figure 1 and Figure 9In this embodiment, a transverse mechanism 600 is required to enable the rotor to move between the magnetic testing device 200 and the magnetic ring clamping device 300 and to automatically load and unload materials. Specifically, the lateral movement mechanism 600 includes a lateral movement slide rail 610, a lateral movement connecting assembly 620, a lateral movement gripper assembly 630, a first driving member, a second driving member 650, and a third driving member 660. The lateral movement slide rail 610 is elongated, and its length direction is left-right. One end of the lateral movement connecting assembly 620 is slidably connected to the lateral movement slide rail 610, and the other end of the lateral movement connecting assembly 620 is connected to the lateral movement gripper assembly 630. The first driving member is located below the lateral movement slide rail 610 and drives the lateral movement connecting assembly 620 to move left-right along the lateral movement slide rail 610. The second driving member 650 is located on the lateral movement connecting assembly 620 and drives the lateral movement gripper assembly 630 to move up-down. The third driving member 660 is located on the lateral movement connecting assembly 620 and drives the second driving member 650 and the lateral movement gripper assembly 630 to move back-and-forth together. The lateral gripper assembly 630 includes a lateral gripper drive 631 and a lateral gripper 632. The lateral gripper drive 631 is connected to the lateral connection assembly 620, and the lateral gripper drive 631 drives the V-shaped lateral gripper 632 to open and close. Here, the first drive member, the second drive member 650, and the third drive member 660 are all cylinders, but in other embodiments, they may also be, but are not limited to, drive motors, etc. In actual operation, the first driving member drives the transverse gripper assembly 630 to move in front of the magnetic detection table 240. The transverse gripper driving member 631 drives the V-shaped transverse chuck 632 to open and close to grip the upper part of the rotor's central shaft. The first driving member drives the transverse gripper assembly 630 to move laterally in front of the pressure ring loading table 320. Then, the third driving member 660 drives the transverse gripper assembly 630 to move forward onto the pressure ring loading table 320. After that, the transverse gripper driving member 631 drives the transverse chuck 632 to open, so that the rotor is placed on the pressure ring loading table 320. After the magnetic ring is pressed onto the rotor, the lateral gripper drive 631 drives the lateral gripper 632 to open and close to grip the rotor. Then, the first drive unit drives the lateral gripper assembly 630 to move to the front of the transfer platform at the intermediate position, located next to the pressing ring loading table 320. Then, the third drive unit 660 drives the lateral gripper assembly 630 to move forward to the transfer platform at the intermediate position. After that, the lateral gripper drive 631 drives the lateral gripper 632 to open, so that the rotor is placed on the transfer platform at the intermediate position. Finally, the rotor with the pressed magnetic ring is moved to the next assembly process at the intermediate position. In addition, considering that the heights of the magnetic detection table 240, the pressing ring loading table 320, and the loading table at the intermediate position may be inconsistent, the lateral gripper assembly 630 can also move up and down through the second drive unit 650, thereby realizing the height adjustment of the lateral gripper assembly 630.

[0060] Please see Figure 1 , Figure 6 and Figure 7In this embodiment, the pressure ring loading platform 320 includes a pressure plate 321, a support base plate 322, multiple spaced support columns 323, a pressure positioning component 324, and a pressure position sensor 325. The support base plate 322 is located below the pressure plate 321, and is fixedly connected to the support columns 323. The upper end of the support column 323 passes through the support base plate 322 and is fixedly connected to the pressure plate 321. The pressure plate 321 is provided with a pressure positioning boss 326, and the pressure positioning component 324 is provided on the pressure positioning boss 326 and protrudes upward in a strip shape. The pressure position sensor 325 is located behind the pressure positioning boss 326. After the rotor's magnetism is measured, the rotor is picked up by the transverse mechanism 600 and placed on the pressure positioning boss 326 of the pressure ring loading platform 320. During placement, the pressure positioning component 324 achieves the positioning function of the rotor by inserting into the bottom of the rotor. After the rotor is placed, the position sensor behind it will detect that the rotor is in the pressing position and send a relevant signal to the control system. Then, the control system controls the pressing mechanism 310 to complete the pressing of the magnetic ring.

[0061] Please see Figure 1 and Figure 6 In this embodiment, the pressing mechanism 310 includes a pressing bracket 311, a pressing cylinder assembly, and a pressure sensor. The pressing bracket 311 is fixed on the machine base 100. The pressing cylinder assembly includes a pressing cylinder 312 and a pressing head 313. The pressing cylinder 312 is fixed on the top plate of the pressing bracket 311, and the upper end of the pressing head 313 is connected to the pressing cylinder 312 in a driving connection. The pressure sensor is located on the pressing head 313. The magnetic ring is pre-fitted onto the upper end of the central shaft of the rotor, which is positioned on the pressing positioning boss 326. The pressing head 313 is driven downward by the pressing cylinder 312 to press and fix the magnetic ring downward at the upper step of the central shaft of the rotor. Here, during the pressing process of the magnetic ring, the pressure change detected by the pressure sensor can be used to determine whether the magnetic ring has been pressed into place. In addition, the press head 313 is provided with an axially oriented ejector pin. The upper end of the ejector pin is fitted with a spring, and the lower end of the ejector pin is also provided with a tapered protrusion. This protrusion can cooperate with the positioning recess at the upper end of the rotor's central shaft, thereby realizing the axial alignment and positioning of the rotor during the pressing of the magnetic ring. In this way, the rotor is not easy to shift or swing during the pressing, thus ensuring that the pressing position of the magnetic ring is accurate and the process is smooth.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
