[0002] The motor rotor consists of a rotor housing, a rotor shaft, and a magnetic ring. The magnetic ring is a permanent magnet with N north and south magnetic poles, which rotates along with the rotor. The magnetic ring is typically composed of an iron ring and a magnetic strip ring disposed on the inner surface of the iron ring. The magnetic strip ring is formed by bending and connecting strips of magnetic material end-to-end to create a circular structure. During motor rotor assembly, a machine is used to press the magnetic strip ring into the rotor housing.

[0029] A fully automatic magnetic strip installation device for motor manufacturing, such as Figure 1 As shown, the system includes a first feeding device 1, a second feeding device 2, a mounting platform 3, a magnetic strip bending and pressing mechanism 4, and an ejection device. The first feeding device 1 is located on the side of the mounting platform 3, and the second feeding device 2 is located on the mounting platform 3. Several mounting seats 5 are provided on the mounting platform 3 on the side of the second feeding device 2. The magnetic strip bending and pressing mechanism 4 is located on the mounting platform 3 and above it. The first feeding device 1 and the second feeding device 2 are used to feed the rotor housing into the mounting seats 5 on the mounting platform 3. The magnetic strip bending and pressing mechanism 4 is used to press the straight magnetic strip into a circle and press the formed magnetic strip into the mounting seat 5.
[0030] like Figure 2As shown, the first feeding device includes a support frame 6, with fixed frames 7 on both sides of the top of the support frame 6, and drive shafts 8 on both sides of the fixed frames 7. A first conveyor belt 9 and a second conveyor belt 10 are connected to the drive shafts 8, and a placement gap 11 is provided between the first conveyor belt 9 and the second conveyor belt 10. A motor that drives the rotation of one of the drive shafts 8 on the fixed frame 7 is connected to the side of the drive shaft 8. After the drive shaft 8 rotates, it drives the first conveyor belt 9 and the second conveyor belt 10 to move. The placement gap 11 between the first conveyor belt 9 and the second conveyor belt 10 is provided to facilitate the accommodation of the rotor shaft on the rotor housing. The rotor housing is placed vertically on the first conveyor belt 9 and the second conveyor belt 10. The rotor shaft in the middle of the rotor housing passes through the placement gap 11. The rotor housing is transported to the side of the second feeding device 2 by the first conveyor belt 9 and the second conveyor belt 10.
[0031] like Figure 3As shown, the second feeding device includes a lifting plate 12, a slide rail 13 on the lifting plate 12, a translation plate 14 slidably mounted on the slide rail 13, a first finger cylinder 15 and a second finger cylinder 16 on the translation plate 14, and a rotary cylinder 17 connected to the rear end of the second finger cylinder 16. A second lifting motor 43 is located below the mounting platform 3, and the output end of the second lifting motor 43 passes through the mounting platform 3 and is connected to the bottom of the lifting plate 12. The second lifting motor 43 is used to drive the lifting plate 12, the translation plate 14, and the first finger cylinder 15 and the second finger cylinder 16 on the plate to move up and down. An electric telescopic rod 44 is horizontally mounted on the lifting plate 12, and a stop block is connected to the side of the translation plate 14. The output end of the electric telescopic rod 44 is connected to the stop block, and the electric telescopic rod 44 can drive the plate to slide on the slide rail 13 of the lifting plate 12. The gripper portions of the first finger cylinder 15 and the second finger cylinder 16 extend outward toward one side of the translation plate 14. When the second feeding device operates, it first raises the lifting plate 12 so that the height of the gripper portion on the first finger cylinder 15 is higher than the height of the rotor shell on the first feeding device 1. Then, by moving the translation plate 14, the gripper portion on the first finger cylinder 15 moves above the rotor shell. The lifting plate 12 descends, and the gripper portion fits onto both sides of the rotor shell. Then, the first finger cylinder 15 clamps the rotor shell. Finally, the lifting plate 12 is raised again, and the translation plate 14 is moved to move the rotor shell to the mounting seat 5 on the mounting platform 3. In this embodiment, the first finger cylinder 15 and the mounting seat... Multiple mounting bases 5 can be set, so that by moving the lifting plate 12 and the translation plate 14 once, multiple rotor shells can be sent into the mounting base 5. The spacing between the mounting bases 5 is the same, and the spacing between the first finger cylinders 15 is also the same. The middle mounting base 5 is located directly below the magnetic strip bending and pressing mechanism 4. After the magnetic strip bending and pressing mechanism 4 rounds the magnetic strip, it is pressed into the rotor shell on the mounting base 5 directly below. Then, the rotor shell is clamped by the second finger cylinder 16. By using the rotating cylinder 17 at the rear end of the second finger cylinder 16, the rotor shell can be rotated 180° and placed on the fixed base 42 on one side of the mounting base 5, and magnetized by the magnetizing device. In this embodiment, the mounting base 5 and the fixed base 42 are both nearly hollow cylindrical structures. The rotor shell on the fixed base 42 can be ejected and unloaded by the ejection device.
[0032] like Figure 7As shown, the ejector device includes a connecting plate 35, a fixing plate 36 connected to one side of the connecting plate 35, a guide rail on one side of the fixing plate 36, an upper top plate and a lower bottom plate above and below the fixing plate 36, a stepper motor 37 on the lower bottom plate, a lead screw 38 connected to the output end of the stepper motor 37, the top of the lead screw 38 being rotatably connected to the upper top plate, a nut seat 39 slidingly mounted on the lead screw 38, one side of the nut seat 39 being slidably connected to the guide rail, and a horizontal plate 40 connected to the other side of the nut seat 39, with a push rod 41 connected above the horizontal plate 40. By driving the stepper motor 37, the nut seat 39 can be moved up and down, thereby moving the push rod 41 up and down. During the upward movement of the push rod 41, the rotor shaft on the rotor housing can be ejected, thus ejecting the entire rotor housing.
[0033] like Figure 4-6 As shown, the magnetic strip bending and pressing mechanism 4 includes a worktable 18, a support plate 19 above the worktable 18, a drive motor 20 on the support plate 19, the output end of the drive motor 20 extending downward and connected to a die head 21, shaping devices on the left and right sides of the die head 21, and a material conveying device on the rear side of the die head 21. A first lifting motor 22 is mounted on the support plate 19, and its output end is connected to the worktable 18. Support columns 23 are connected around the support plate 19 and fixed to the mounting platform 3. Sleeves 24 are connected around the worktable 18 and slidably mounted on the support columns 23. The support plate 19 is fixed to the mounting platform 3 by four support columns 23. The first lifting motors 22 on both sides of the support plate 19 can drive the worktable 18 to move up and down along the support columns 23.
[0034] The bending and shaping device includes a first bending device and a second bending device. The first bending device includes a first motor 25, which is connected to a first shaping seat 26. The first shaping seat 26 has a semi-circular groove 27. The second bending device includes a second motor 28, which is connected to a second shaping seat 29. The second shaping seat 29 also has a semi-circular groove 27. A first motor 25 seat and a second motor 28 seat are fixedly mounted on both sides of the worktable 18. The first motor 25 and the second motor 28 are respectively mounted on the first motor 25 seat and the second motor 28 seat. The first motor 25 is fixed on the first motor 25 seat and pushes the first shaping seat 26 to move. The second motor 28 is fixed on the second motor 28 seat and pushes the second shaping seat 29 to move.
[0035] When the feeding device moves the square magnetic strip to the front end of the first shaping seat 26, the center points of the square magnetic strip, the semi-circular groove 27 at the front end of the first shaping seat 26, and the die head 21 are all on the same straight line. When the first motor 25 pushes the first shaping seat 26 toward the die head 21, the two sides of the front end of the first shaping seat 26 will abut the magnetic strip, driving the magnetic strip toward the die head 21 until the center point of the magnetic strip abuts the end of the center of the die head 21. At this time, under the action of the semi-circular groove 27 and the die head 21, the square magnetic strip will first be bent into a U-shaped structure. Then, the second motor 28 is driven to move the second shaping seat 29 toward the die head 21, and the second shaping seat 29 and the two semi-circular grooves 27 on the first shaping seat 26 can form a complete circle. Under the action of the second shaping seat 29 and the first shaping seat 26, the magnetic strip is bent into a ring shape.
[0036] The material conveying device includes a push rod (not shown) and a conveying platform 31, as shown in the figure. The conveying platform 31 is used to place the strip-shaped magnetic strips. A baffle 32 is provided at the front end of the conveying platform 31, and a corresponding drive mechanism is provided on the side of the baffle 32. The drive mechanism has a push rod 30 and a pushing mechanism, such as an electric cylinder, inside it to move the push rod 30. Its direction of movement is shown by arrow K. A third motor 33 is provided on the side of the conveying platform 31. The third motor 33 is connected to a push plate 34. The pushing direction of the push plate 34 is shown by arrow L, and the pushing direction of the push plate 34 is perpendicular to the pushing direction of the push rod. During the pushing process, several square magnetic strips are first placed on the conveying platform 31. Then, the pusher plate is moved by the third motor 33 to make the magnetic strips fall into the channel between the conveying platform 31 and the baffle 32. Then, the push rod pushes the magnetic strips to the front end of the first shaping seat 26 and presses them into a ring shape. Finally, the drive motor 20 drives the mold head 21 to move downward, so that the pressed magnetic strips move to the position specified by the motor. At the same time as the mold head 21 moves downward, the first lifting motor 22 also drives the worktable 18 to descend.
[0037] This embodiment includes a first feeding device 1 and a second feeding device 2, which can feed the rotor shell into a designated position. Then, the magnetic strip is rounded by the magnetic strip bending and pressing mechanism 4. Finally, the magnetic strip is pressed into the rotor shell by a servo motor and the bottom of the die head 21. This solution can accurately place the rotor shell under the die head 21, improving the automation level and yield of magnetic strip installation. At the same time, this solution includes an ejection device, which can eject the assembled rotor shell.
[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
