Description

Technical Field

[0001] The present invention relates to the technical field of permanent magnet motor processing, and more particularly to a rotor embedding device for permanent magnet motor processing. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels and adopt new in-vehicle power devices), integrating advanced technologies in vehicle power control and drive, and forming vehicles with advanced technical principles, new technologies, and new structures. Permanent magnet motors have become one of the core components of new energy vehicle drive systems due to their high efficiency, high power density, and excellent performance.

[0003] During the processing of the permanent magnet motor of a new energy vehicle, when embedding magnetic steel into the rotor, generally only one magnetic steel can be embedded into a single magnetic slot at a time, and there are at least 4 magnetic slots on the rotor. Therefore, during the process of embedding the magnetic steel, multiple repeated operations are required, which reduces the embedding efficiency of the rotor. At the same time, after the magnetic steel is embedded, it also needs to be adhesively treated. During this process, the rotor needs to be transported from the fitting position to the adhesive position, increasing the working time, and it is impossible to quickly embed and adhesively treat the rotor.

[0004] Therefore, a rotor embedding device for permanent magnet motor processing is needed to solve the above problems. Summary of the Invention

Detailed implementation manners

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0033] The following describes the specific implementation of the present invention in detail with specific embodiments.

[0034] In an embodiment of the present invention, refer to Figure 1 and Figure 2, A rotor embedding device for processing a permanent magnet motor 411, comprising a workbench 1. A placing disk 2 is rotatably provided on the workbench 1. Four placing guide posts 201 for placing the rotor body 9 are circumferentially and equidistantly distributed on the placing disk 2. A feeding assembly 3 is installed on the workbench 1. The feeding assembly 3 includes a feeding guide frame 301 installed on the workbench 1 and a first fixed cylinder 305 arranged directly above one of the placing guide posts 201. A plurality of through grooves corresponding to the magnetic grooves distributed on the rotor body 9 are circumferentially distributed at the bottom of the first fixed cylinder 305. A plurality of magnetic steel pieces 302 are placed on the feeding guide frame 301. A material distributing assembly 4 is provided at the top of the first fixed cylinder 305. A pushing assembly 6 is movably arranged in the first fixed cylinder 305. A switching assembly 5 is arranged between the material distributing assembly 4 and the pushing assembly 6. A bonding assembly 7 connected to the material distributing assembly 4 is arranged directly above another placing guide post 201. A blower module 8 is arranged at one end of the workbench 1 away from the feeding assembly 3 and directly above the corresponding placing guide post 201.

[0035] In this embodiment, through the placing guide post 201, the rotor body 9 can be guided for placement and synchronous rotation of the rotor body 9 can be achieved. Through the cooperation of the feeding assembly 3 and the material distributing assembly 4, intermittent feeding processing of the magnetic steel pieces 302 can be realized. Through the cooperation of the switching assembly 5 and the pushing assembly 6, all the magnetic steel pieces 302 at the corresponding position can be pushed to the rotor body 9 at one time to achieve rapid embedding, avoiding the low efficiency of the existing method of only embedding a single magnetic steel piece 302 into the corresponding magnetic groove at a time. Through the switching assembly 5 and the bonding assembly 7, the rotor body 9 embedded with the magnetic steel pieces 302 can be bonded, ensuring the firmness between the magnetic steel pieces 302 and the rotor body 9. Through the blower module 8, the bonded rotor body 9 can be quickly air-dried. At the same time, through the switching assembly 5, intermittent rotation of the placing disk 2 can be achieved, facilitating the automatic processing of the rotor body 9 in accordance with the sequence of embedding - bonding - air-drying, and improving the embedding efficiency of the rotor body 9;

[0036] Among them, the feeding assembly 3, the bonding assembly 7 and the blower module 8 are distributed along the outer side of the placing disk 2 in a clockwise direction, facilitating the orderly processing of the rotor body 9. The feeding assembly 3 further includes a pushing plate 303 slidably arranged in the feeding guide frame 301. One end of the pushing plate 303 close to the first fixed cylinder 305 abuts against the magnetic steel piece 302 away from the first fixed cylinder 305. A spring 304 is connected between the feeding guide frame 301 and the pushing plate 303. Through the connection of the spring 304 and the pushing plate 303, the magnetic steel piece 302 can be pushed into the interior of the first fixed cylinder 305, facilitating the orderly feeding of the magnetic steel piece 302. The blower module 8 can be composed of a C-shaped frame and a blower.

[0037] In an embodiment of the present invention, refer to Figures 1 - 3, the material distribution component 4 includes a mounting plate 401 installed on the top of the first fixed cylinder 305. A first rotating rod 403 is rotatably provided on the mounting plate 401. One end of the first rotating rod 403 is connected to a material distribution plate 402 rotatably arranged at the inner bottom of the first fixed cylinder 305. A plurality of placement grooves are circumferentially distributed on the outer side wall of the material distribution plate 402. The number of the placement grooves is the same as the number of the through grooves. The size of the placement grooves is slightly larger than the size of the magnetic steel 302. The end of the first rotating rod 403 away from the material distribution plate 402 is connected to an intermittent turntable 404 rotatably arranged on the top of the mounting plate 401. A motor 411 is installed on the mounting plate 401. A driving pulley 410 is connected to the output shaft of the motor 411. A residual rotating wheel 406 that is intermittently and slidably engaged with the intermittent turntable 404 is rotatably provided on the mounting plate 401. A fixed sliding column 405 that is intermittently and slidably engaged with the intermittent turntable 404 is connected to the outer end of the residual rotating wheel 406. A second rotating rod 407 is rotatably arranged inside the residual rotating wheel 406. A driven pulley 408 is connected to the top of the second rotating rod 407. The driving pulley 410 and the driven pulley 408 are connected by a first transmission belt 409.

[0038] In this embodiment, in the initial state, through the switching component 5, the residual rotating wheel 406 and the second rotating rod 407 rotate synchronously. One magnetic steel 302 on the material guiding frame 301 close to the first fixed cylinder 305 corresponds to one placement groove on the material distribution plate 402. The motor 411 drives the driving pulley 410 to rotate. The driving pulley 410 drives the second rotating rod 407 to rotate synchronously by connecting with the driven pulley 408 through the first transmission belt 409. The second rotating rod 407 drives the residual rotating wheel 406 to rotate synchronously by rotating synchronously with the residual rotating wheel 406. The residual rotating wheel 406 drives the intermittent turntable 404 to rotate intermittently by the intermittent sliding fit between the fixed sliding column 405 and the intermittent turntable 404. The intermittent turntable 404 drives the material distribution plate 402 to rotate synchronously and intermittently by connecting with the first rotating rod 403. The material distribution plate 402 can sequentially fill a plurality of magnetic steels 302 into a plurality of placement grooves through its own intermittent rotation, which is convenient for embedding the magnetic steels 302 into the rotor body 9 at one time later, realizing the orderly placement of the magnetic steels 302.

[0039] Among them, a plurality of arc-shaped grooves and a plurality of sliding grooves are provided on the outer side wall of the intermittent turntable 404. The arc-shaped grooves and the sliding grooves are arranged at intervals. The arc-shaped grooves correspond to the placement grooves one by one. The material distribution plate 402 is made of magnetic material, which can ensure the fit between the material distribution plate 402 and the magnetic steel 302, and avoid the phenomenon that the magnetic steel 302 falls through the through groove at the bottom of the first fixed cylinder 305 during the rotation process.

[0040] In an embodiment of the present invention, see Figures 1 - 3 、 Figures 5 - 6, the pusher component 6 includes a third rotating rod 601 rotatably arranged on the outer wall of the first fixed cylinder 305. An inclined ring groove 602 is provided on the outer side wall of the third rotating rod 601. A strip-shaped limiting groove is provided on the side wall of the first fixed cylinder 305 close to the third rotating rod 601. A lifting plate 603 is slidably arranged on the inner wall of the first fixed cylinder 305. One end of the lifting plate 603 is movably matched with the third rotating rod 601. A third sliding column 605 slidably matched with the inclined ring groove 602 is provided on the lifting plate 603. A plurality of pusher rods 604 are circumferentially distributed on the side of the lifting plate 603 close to the placing plate 2 of the workbench 10. The pusher rods 604 correspond to the through grooves at the bottom of the first fixed cylinder 305 one by one.

[0041] In this embodiment, in the initial state, the third sliding column 605 is slidably matched with the highest point of the inclined ring groove 602, and the lifting plate 603 is at the highest point. Through the switching component 5, when the second rotating rod 407 is connected to the third rotating rod 601, the second rotating rod 407 and the third rotating rod 601 rotate synchronously. When the magnet 302 needs to be embedded into the rotor body 9, the motor 411 drives the driving pulley 410 to rotate. The driving pulley 410 drives the second rotating rod 407 to rotate synchronously in a manner of being connected by the first transmission belt 409 and the driven pulley 408. The second rotating rod 407 drives the third rotating rod 601 to rotate by rotating synchronously with the third rotating rod 601. The third rotating rod 601 drives the lifting plate 603 to move downward by the sliding cooperation of the inclined ring groove 602 and the third sliding column 605 and the sliding cooperation of the lifting plate 603 and the strip-shaped limiting groove. The lifting plate 603 can push the corresponding magnet 302 downward by driving the pusher rods 604 to move downward synchronously;

[0042] When the third sliding column 605 is matched with the lowest point of the inclined ring groove 602, the lifting plate 603 moves down to the lowest point. At this time, the pusher rod 604 pushes the magnet 302 into the magnetic groove of the rotor body 9, and all the magnets 302 can be embedded at one time, avoiding the low efficiency of only being able to embed a single magnet 302 at a time and realizing the rapid and efficient embedding of the magnets 302;

[0043] When the third rotating rod 601 continues to rotate, the third rotating rod 601 drives the lifting plate 603 to move upward by the sliding cooperation of the inclined ring groove 602 and the third sliding column 605 and the sliding cooperation of the lifting plate 603 and the strip-shaped limiting groove. When the third sliding column 605 is matched with the highest point of the inclined ring groove 602, the lifting plate 603 resets;

[0044] Wherein, the distance of the inclined ring groove 602 in the vertical direction is the distance from the bottom of the pusher rod 604 to the top of the rotor body 9. The pusher rod 604 is made of non-magnetic material, which can effectively avoid the problem that after the magnet 302 is embedded into the magnetic groove, the pusher rod 604 moves upward and accidentally drives the magnet 302 to move upward.

[0045] In one embodiment of the present invention, refer to Figures 1 - 5 and Figures 7 - 8 , the switching component 5 includes a lifting frame 501 movably arranged between the mounting plate 401 and the workbench 1. A plurality of electric cylinders 502 are connected between the lifting frame 501 and the mounting plate 401. One end of the lifting frame 501 close to the first fixed cylinder 305 is connected with a first collar 503. A first lifting cylinder 504 which is sleeved on the outer side of the second rotating rod 407 in a sliding and rotating manner is arranged inside the first collar 503. A first external tooth ring 505 is arranged on the outer side wall of one end of the first lifting cylinder 504 close to the residual rotating wheel 406. A second external tooth ring 506 is arranged on the outer side wall of the other end of the first lifting cylinder 504. A first internal tooth groove 507 which is movably meshed with the first external tooth ring 505 is arranged on the inner side wall of one end of the residual rotating wheel 406 close to the first lifting cylinder 504. A second internal tooth groove 508 which is movably meshed with the second external tooth ring 506 is arranged at one end of the third rotating rod 601 close to the first lifting cylinder 504. A detection hole is arranged on the first fixed cylinder 305. A bracket 512 is arranged at the detection hole. A photoelectric sensor 513 is installed on the bracket 512.

[0046] In this embodiment, in the initial state, the lifting frame 501 is at the highest point. The first external tooth ring 505 is meshed with the first internal tooth groove 507, and the second external tooth ring 506 is far away from the second internal tooth groove 508. At this time, synchronous connection is achieved between the second rotating rod 407 and the residual rotating wheel 406, and the orderly placement of the magnetic steel 302 can be realized. When the photoelectric sensor 513 detects that the placement grooves on the material distribution plate 402 are all provided with the magnetic steel 302, the motor 411 stops working first. The electric cylinder 502 extends downward and drives the lifting frame 501 to move downward. The lifting frame 501 drives the first lifting cylinder 504 to move downward synchronously in a way that the first collar 503 is rotationally matched with the first lifting cylinder 504, so as to release the meshing between the first external tooth ring 505 and the first internal tooth groove 507 and realize the meshing between the second external tooth ring 506 and the second internal tooth groove 508. Then, the motor 411 works and drives the second rotating rod 407 to rotate synchronously. The second rotating rod 407 drives the third rotating rod 601 to rotate synchronously in a way that the second external tooth ring 506 is meshed with the second internal tooth groove 508, and the downward movement of the magnetic steel 302 can be realized, which is convenient for the primary embedding of the magnetic steel 302.

[0047] When the photoelectric sensor 513 detects that the corresponding placement groove is in an empty state, the motor 411 stops working first, the electric cylinder 502 contracts upward and drives the lifting frame 501 to move upward. The lifting frame 501 drives the first lifting cylinder 504 to move upward synchronously in a way that the first collar 503 rotates with the first lifting cylinder 504, so as to release the engagement between the second external gear ring 506 and the second internal gear groove 508, and realize the engagement between the first external gear ring 505 and the first internal gear groove 507. Then, the motor 411 works and drives the second rotating rod 407 to rotate synchronously. The second rotating rod 407 drives the waste wheel 406 to rotate synchronously by the engagement between the first external gear ring 505 and the first internal gear groove 507, which can realize the re - orderly filling of the magnetic steels 302 in several placement grooves, can realize the switching of different working states, and improve the practicability of the device.

[0048] Among them, the first lifting cylinder 504 can slide along the axial direction of the second rotating rod 407.

[0049] In addition, a fixed column 202 is installed at the center of the placement disc 2. A guiding ring groove 511 is arranged on the fixed column 202. A second lifting cylinder 509 connected to the lifting frame 501 is movably sleeved outside the fixed column 202. An elastic sliding column 510 that slidably cooperates with the guiding ring groove 511 is slidably arranged on the inner wall of the second lifting cylinder 509. The guiding ring groove 511 is composed of four guiding groove groups that are evenly circumferentially distributed and connected end to end. The guiding groove group is composed of a second groove 5113, a vertical groove 5111, a first groove 5112, and a spiral groove 5114 connected in sequence. The depth of the second groove 5113 is greater than the depth of the vertical groove 5111. The depth of the first groove 5112 is greater than the depth of the end of the spiral groove 5114 close to the first groove 5112. The vertical groove 5111 and the first groove 5112 are smoothly transitioned. The second groove 5113 corresponds to and is smoothly transitioned with the end of the spiral groove 5114 far from the first groove 5112.

[0050] In the initial state, the lifting frame 501 is at the highest point, and the elastic sliding column 510 corresponds to the first groove 5112. At this time, several magnets 302 can be orderly filled into the placement grooves of the material distribution plate 402. When it is necessary to embed the magnet 302 into the magnetic groove of the rotor body 9, the electric cylinder 502 drives the lifting frame 501 to move downward, so that the magnet 302 can be embedded once. At the same time, the lifting frame 501 drives the second lifting cylinder 509 to move downward synchronously, and the second lifting cylinder 509 drives the elastic sliding column 510 to move downward synchronously, so that the elastic sliding column 510 corresponds to the second groove 5113; when the lifting frame 501 moves upward, the lifting frame 501 drives the elastic sliding column 510 to move upward synchronously by connecting with the second lifting cylinder 509 and the sliding fit between the second lifting cylinder 509 and the elastic sliding column 510. Since the depth of the second groove 5113 is greater than the depth of the vertical groove 5111 and the second groove 5113 is smoothly transitioned to the end of the spiral groove 5114 away from the first groove 5112, the elastic sliding column 510 slides from the bottom of the spiral groove 5114 to the top of the spiral groove 5114. During the upward movement of the elastic sliding column 510, since the second lifting cylinder 509 can only move in the vertical direction, the fixed column 202 drives the placement plate 2 to rotate clockwise by ninety degrees through the sliding fit between the guide ring groove 511 and the elastic sliding column 510 and the sliding fit between the placement plate 2 and the workbench 1, so that the rotor body 9 embedded with the magnet 302 can be rotated to the lower part of the bonding assembly 7, the bonded rotor body 9 can be rotated to the lower part of the fan module 8, and the air-dried rotor body 9 can be rotated to the empty station, which is convenient for the staff to take out the rotor body 9 after multiple treatments and put in the rotor body 9 to be treated, realizing the station adjustment of the rotor body 9, improving the work efficiency and avoiding the low efficiency of manual adjustment.

[0051] In an embodiment of the present invention, referring to Figures 1 - 6 , the bonding assembly 7 includes a connecting frame 704 fixedly connected to the outside of the mounting plate 401. The bottom of the connecting frame 704 is rotatably connected with a second fixed cylinder 701. An elevating rod 705 is slidably arranged inside the second fixed cylinder 701. The top of the elevating rod 705 is rotatably provided with a second collar 706 connected to the lifting frame 501. The bottom of the elevating rod 705 is connected with a cross plate 707. The outer end of the cross plate 707 is connected with a glue injector 709 that is in movable contact with the top of the rotor body 9. A glue storage tank 708 communicating with the glue injector 709 is arranged on the cross plate 707. A first ring groove 702 is arranged at the top of the connecting frame 704. A second ring groove 710 is arranged at the top of the third rotating rod 601. A second transmission belt 703 is connected between the first ring groove 702 and the second ring groove 710.

[0052] In this embodiment, when the lifting frame 501 is at the highest point, the cross plate 707 and the glue injector 709 are at the highest point, and the glue injector 709 is away from the corresponding rotor body 9. At this time, the second outer gear ring 506 is not engaged with the second inner tooth groove 508, and the third rotating rod 601 and the second fixed cylinder 701 do not rotate. When the lifting frame 501 moves down, the second outer gear ring 506 is engaged with the second inner tooth groove 508, and the second rotating rod 407 and the third rotating rod 601 rotate synchronously. At the same time, the lifting frame 501 drives the lifting rod 705 to move downward by connecting with the second ring 706, and the lifting rod 705 drives the glue injector 709 and the glue storage tank 708 to move downward synchronously by connecting with the cross plate 707, so that the glue injector 709 contacts the magnetic groove of the rotor body 9.

[0053] When the third rotating rod 601 rotates one circle, the third rotating rod 601 drives the second fixed cylinder 701 to rotate one circle through the transmission connection between the second ring groove 710, the second transmission belt 703 and the first ring groove 702, and the second fixed cylinder 701 drives the horizontal plate 707 to rotate one circle by sliding with the lifting rod 705. The horizontal plate 707 drives the glue injector 709 to rotate synchronously to achieve the bonding process between the magnetic groove of the rotor body 9 and the corresponding magnetic steel 302, so that the multiple linkage of the device can be realized;

[0054] When the lifting frame 501 moves upward, the second outer tooth ring 506 and the second inner tooth groove 508 are disengaged, so that the position adjustment of the rotor body 9 in different states can be realized, which facilitates the orderly processing of the rotor body 9;

[0055] Among them, the glue storage tank 708 is provided with a screw cap on the top, and an observation window is provided in the middle of the glue storage tank 708. The screw cap allows the staff to add glue in time, and the observation window allows the staff to observe the glue content in the glue storage tank 708 at any time.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
