[0018] The beneficial effects of this invention are as follows:

[0019] 1. The motor module drives the turntable to rotate, which in turn drives several assembly slots to rotate. Therefore, the various components of the brushless rotor can be placed into the assembly slots in sequence to assemble the brushless rotor. The dustproof sheet vibratory feeder can vibrate and convey the dustproof sheet to the dustproof sheet linear feed vibrator. The first gripping displacement mechanism can drive the dustproof sheet positioning pin and the dustproof sheet positioning shaft to grip and convey the dustproof sheet at the end of the dustproof sheet linear feed vibrator, thereby gripping the dustproof sheet into the assembly slot. The dustproof sheet positioning sleeve can also provide positioning support for the dustproof sheet to facilitate subsequent assembly of the dustproof sheet.

[0020] 2. The operator can place the magnetic sheet into several magnetic insertion slots, then place the iron core on the upper end of the magnetic insertion base, and drive several magnetic blocks to move upwards simultaneously through the output shaft of the first electric cylinder, so as to push the magnetic sheet in the magnetic insertion slot into the iron core, thereby completing the magnetic insertion work of the iron core. The iron core with the magnetic insertion completed can be placed in the feeding trough, so that the iron core is located in the feeding trough for neat placement. Then, the motor pulley group can drive the moving seat to move left and right along the first mounting frame, thereby driving the second electric cylinder to move left and right. Then, the output shaft of the second electric cylinder can drive the feeding sleeve to move up and down, so as to pick up and transfer the iron core in the feeding trough, thereby transferring the iron core to the assembly slot on the turntable for subsequent assembly work.

[0021] 3. The fan blade can be vibrated and conveyed by the fan blade vibrating plate, so that the fan blade can be conveyed to the fan blade linear feeding vibrator. The second gripping displacement mechanism can drive the fan blade positioning pin and the fan blade positioning shaft to grip and convey the fan blade at the end of the fan blade linear feeding vibrator, so that the fan blade can be gripped into the assembly slot. The fan blade positioning sleeve can also provide positioning support for the fan blade, so as to facilitate the subsequent assembly of the fan blade.

[0022] 4. By adjusting the position of the adjusting plate on the iron core rack, the distance between the iron core rack and the adjusting plate can be adjusted, thus facilitating the placement of drive shafts of different lengths in the iron core trough. The output shaft of the third electric cylinder can drive the lifting plate to move up and down, thereby driving the unloading rack to move up and down. When the unloading rack moves downward, the drive shaft at the front end of the iron core trough can slide into the unloading rack. Subsequently, the unloading rack can move upward, driving the drive shaft upward. The output shaft of the fourth electric cylinder can drive the limit stop plate to move downward, thus blocking the drive shaft and ensuring that only a single drive shaft can pass between the limit stop plate and the surface of the iron core trough, ensuring that only a single drive shaft passes at a time. The drive shaft slides into the unloading rack, thus enabling the assembly of each drive shaft. The output shaft of the pusher cylinder can drive the unloading rack forward, thereby pushing the drive shaft out of the unloading rack and facilitating its insertion into the clamping and flipping mechanism for clamping and fixing. The clamping and flipping mechanism can then be rotated 90° to change the drive shaft from a horizontal to a vertical position. Subsequently, the first hydraulic cylinder can drive the first pressure block to press the drive shaft downward. When the brushless rotor component rotates above the servo press, the servo press, in conjunction with the first pressure block, can insert the drive shaft into the iron core for assembly. At the same time, the drive shaft can pass through the fan blade to fix the fan blade, thus completing the assembly of the drive shaft.

[0023] 5. The upper bearing can be conveyed by the upper bearing vibratory plate, so that the upper bearings can be conveyed one by one to the upper bearing slide rail. When the brushless rotor component rotates to the lower end of the upper bearing slide rail, the upper bearing can fall to the upper end of the brushless rotor drive shaft component. At this time, the output shaft of the second hydraulic cylinder can drive the upper bearing pressure head to move downward, and the lower die pressure head can abut against the bottom of the drive shaft. Finally, the upper bearing can be pressed into the upper end of the drive shaft, thus completing the assembly of the upper bearing.

[0024] 6. The lower bearing can be vibrated and conveyed by the lower bearing vibratory plate, so that the lower bearings can be conveyed one by one to the lower bearing slide rail. When the brushless rotor component rotates to the upper end of the lower bearing slide rail, the lower bearing can fall to the upper end of the lower bearing pressure head. At this time, the output shaft of the third hydraulic cylinder can drive the lower bearing pressure head to move upward, and the upper die pressure head can abut against the top of the drive shaft, and finally press the lower bearing into the lower end of the drive shaft, thereby completing the assembly of the lower bearing.

[0025] 7. The third material handling and displacement mechanism can grab the brushless rotor that has been transferred in the assembly tank and put it onto the belt conveyor. Finally, the brushless rotor can be transported by the belt conveyor so that the staff can collect it for subsequent processing. Attached Figure Description

[0038] like Figures 1 to 10 As shown, an automatic assembly device for brushless rotors includes a workbench 1. A motor module 2 is mounted on the upper end of the workbench 1. A turntable 3 is fixed to the output shaft of the motor module 2. Several assembly slots 4 are formed on the turntable 3. The motor module 2 drives the turntable 3 to rotate, thereby rotating the assembly slots 4. This allows the various components of the brushless rotor to be sequentially placed into the assembly slots 4 to assemble the brushless rotor. Each of the assembly slots 4 contains a fan blade positioning sleeve 5, a core positioning sleeve 6, and a bearing positioning sleeve 7, arranged from top to bottom. These sleeves allow for the positioning and placement of the fan blade, core, and upper and lower bearings, respectively. The workbench 1 also includes:

[0039] Dustproof sheet feeding mechanism 8: The dustproof sheet feeding mechanism 8 includes a dustproof sheet vibrating plate 9 disposed on one side of the workbench 1. A dustproof sheet linear feeding vibrator 10 is disposed at the upper end of the workbench 1, and the dustproof sheet linear feeding vibrator 10 is connected to the output end of the dustproof sheet vibrating plate 9. A dustproof sheet baffle 14 is disposed at the end of the dustproof sheet linear feeding vibrator 10. The dustproof sheet can be vibrated and conveyed by the dustproof sheet vibrating plate 9, so that the dustproof sheet can be conveyed to the dustproof sheet linear feeding vibrator 10 for conveying. The dustproof sheet baffle 14 can prevent the dustproof sheet from falling from the end of the dustproof sheet linear feeding vibrator 10. A first material gripping and displacement mechanism 11 is provided above the workbench 1. The output end of the first material gripping and displacement mechanism 11 is connected to a dustproof sheet positioning pin 12. The lower end of the dustproof sheet positioning pin 12 is connected to a dustproof sheet positioning shaft 13. The first material gripping and displacement mechanism 11 can drive the dustproof sheet positioning pin 12 and the dustproof sheet positioning shaft 13 to grip and transport the dustproof sheet at the end of the dustproof sheet linear feeding vibrator 10, so that the dustproof sheet can be gripped into the assembly slot 4. The dustproof sheet positioning sleeve can also provide positioning support for the dustproof sheet, so as to facilitate the subsequent assembly of the dustproof sheet.

[0040] The first material handling displacement mechanism 11 includes a second column 67 fixedly mounted on the upper end of the workbench 1. A first fixed frame 68 is fixedly mounted on the upper end of the second column 67. A fifth electric cylinder 69 is connected to one side of the first fixed frame 68. A movable second fixed frame 70 is embedded in the first fixed frame 68. The output shaft of the fifth electric cylinder 69 is fixedly connected to one side of the second fixed frame 70. The second fixed frame 70 can be moved left and right along the first fixed frame 68 by the output shaft of the fifth electric cylinder 69. A sixth electric cylinder 71 is installed on the top of the second fixed frame 70. A movable third fixed frame 72 is embedded in the second fixed frame 70, and the output shaft of the sixth electric cylinder 71 is fixedly connected to the top of the third fixed frame 72. A first gripping electric cylinder 73 is installed on the third fixed frame 72, and the dustproof sheet positioning pin 12 is fixedly connected to the output shaft of the first gripping electric cylinder 73. The output shaft of the sixth electric cylinder 71 can drive the third fixed frame 72 to move up and down along the second fixed frame 70, and finally the lateral and longitudinal positions of the third fixed frame 72 can be adjusted, thereby realizing the flexible adjustment of the position of the first gripping electric cylinder 73. Therefore, the first gripping electric cylinder 73 can drive the dustproof sheet positioning pin 12 and the shaft of the dustproof sheet positioning pin 12 to move up and down to realize the gripping and transfer of the dustproof sheet.

[0041] Iron core insertion and feeding mechanism 15: The iron core insertion and feeding mechanism 15 includes an insertion box 16 disposed on one side of the workbench 1. An insertion seat 17 is disposed at the upper end of the insertion box 16. Several insertion slots 18 are opened on the insertion seat 17. A first electric cylinder 19 is installed inside the insertion box 16. Several insertion blocks 20 are fixedly disposed on the output shaft of the first electric cylinder 19. The upper ends of the several insertion blocks 20 are slidably inserted into the several insertion slots 18. The operator can put the magnetic sheet into the several insertion slots 18, and then place the iron core on the upper end of the insertion seat 17. The output shaft of the first electric cylinder 19 drives the several insertion blocks 20 to move upward at the same time, so as to push the magnetic sheet in the insertion slot 18 into the iron core, thereby completing the insertion of the iron core.

[0042] Two first columns 21 are fixedly mounted on the upper end of the workbench 1. A first mounting frame 22 is fixedly mounted on the upper end of the two first columns 21. A slidable movable seat 23 is embedded in the first mounting frame 22.

A rotatable feeding tray 27 is connected to one of the first columns 21. The feeding tray 27 has several feeding slots 28. Workers can place the magnetized iron core into the feeding trough 28, ensuring its neat placement. Then, the motor pulley assembly 24 drives the moving seat 23 to move left and right along the first mounting frame 22, which in turn moves the second electric cylinder 25 left and right. The output shaft of the second electric cylinder 25 then drives the loading sleeve 26 to move up and down, facilitating the extraction and transfer of the iron core from the feeding trough 28 to the assembly slot 4 on the turntable 3 for subsequent assembly. A rotating mechanism (not shown in the figure) is connected below the feeding tray 27 to drive its rotation; its structure is existing technology and will not be described in detail.

[0043] The workbench 1 is also fixed with a bracket 74, on which a number of sensors 75 are installed. The sensors 75 are located below a number of material feeding slots 28. The sensors 75 can sense whether there is an iron core in the assembly slot 4 so that the feeding sleeve 26 can pick up the iron core. The model of the sensor 75 is existing technology, so it will not be described in detail.

[0044] Fan blade feeding mechanism 29: The fan blade feeding mechanism 29 includes a fan blade vibrating plate 30 disposed on one side of the workbench 1. A fan blade linear feeding vibrator 31 is disposed at the upper end of the workbench 1, and the fan blade linear feeding vibrator 31 is connected to the output end of the fan blade vibrating plate 30. A fan blade baffle 35 is disposed at the end of the fan blade linear feeding vibrator 31. The fan blade can be vibrated and conveyed by the fan blade vibrating plate 30, so that the fan blade can be conveyed to the fan blade linear feeding vibrator 31 for conveying. The fan blade baffle 35 can prevent the fan blade from falling from the end of the fan blade linear feeding vibrator 31. A second material gripping and displacement mechanism 32 is provided above the workbench 1. The output end of the second material gripping and displacement mechanism 32 is connected to a fan blade positioning pin 33. The lower end of the fan blade positioning pin 33 is connected to a fan blade positioning shaft 34. The second material gripping and displacement mechanism 32 can drive the fan blade positioning pin 33 and the fan blade positioning shaft 34 to grip and transport the fan blade at the end of the fan blade linear feeding vibrator 31, so that the fan blade can be gripped into the assembly slot 4. The fan blade positioning sleeve 5 can also provide positioning support for the fan blade, so as to facilitate the subsequent assembly of the fan blade.

[0045] The second material handling displacement mechanism 32 includes a third column 76 fixedly mounted on the upper end of the workbench 1. A fourth fixed frame 77 is fixedly mounted on the upper end of the third column 76. A seventh electric cylinder 78 is connected to one side of the fourth fixed frame 77. A movable fifth fixed frame 79 is embedded in the fourth fixed frame 77. The output shaft of the seventh electric cylinder 78 is fixedly connected to one side of the fifth fixed frame 79. The fifth fixed frame 79 can be moved left and right along the fourth fixed frame 77 by the seventh electric cylinder 78. An eighth electric cylinder 80 is installed on the top of the fifth fixed frame 79. A movable sixth fixed frame 81 is embedded in the seventh fixed frame 84, and the output shaft of the eighth electric cylinder 80 is fixedly connected to the top of the sixth fixed frame 81. A second material-gripping electric cylinder 82 is installed on the sixth fixed frame 81, and the fan blade positioning pin 33 is fixedly connected to the output shaft of the second material-gripping electric cylinder 82. The eighth electric cylinder 80 can drive the sixth fixed frame 81 to move up and down along the fifth fixed frame 79, and finally the lateral and longitudinal positions of the sixth fixed frame 81 can be adjusted, thereby the position of the second material-gripping electric cylinder 82 can be flexibly adjusted. Therefore, the fan blade can be gripped and transferred by driving the fan blade positioning pin 33 and the fan blade positioning shaft 34 to move up and down through the second material-gripping electric cylinder 82.

[0046] Iron core loading mechanism 36: The iron core loading mechanism 36 includes an iron core rack 37 mounted on the upper end of the worktable 1. A detachable adjusting plate 38 is connected to the upper side of the iron core rack 37 by screws. One side of the iron core rack 37 and one side of the adjusting plate 38 form an iron core groove 39 for the drive shaft to slide. By adjusting the position of the adjusting plate 38 on the iron core rack 37, the distance between the iron core rack 37 and the adjusting plate 38 can be adjusted, thereby facilitating the placement of drive shafts of different lengths in the iron core groove 39. A third electric cylinder 40 is installed on the upper end of the workbench 1. A lifting plate 41 is connected to one side of the output shaft of the third electric cylinder 40, and the lifting plate 41 abuts against one side of the iron core material trough 39. A feeding rack 42 is connected to the upper end of the lifting plate 41. The lifting plate 41 can be driven to move up and down through the output shaft of the third electric cylinder 40, thereby driving the feeding rack 42 to move up and down. When the feeding rack 42 moves down, the drive shaft at the front end of the iron core material trough 39 can slide into the feeding rack 42. Then, the drive shaft can be driven to move up through the upward movement of the feeding rack 42. A fourth electric cylinder 43 is installed above the iron core material rack 37. The output shaft of the fourth electric cylinder 43 is fixed with a limiting baffle 44, and the limiting baffle 44 cooperates with the unloading rack 42. The output shaft of the fourth electric cylinder 43 can drive the limiting baffle 44 to move downward. Therefore, the limiting baffle 44 can block the drive shaft, so as to ensure that only a single drive shaft can pass between the limiting baffle 44 and the surface of the iron core material rack 39. This ensures that only a single drive shaft slides into the unloading rack 42 each time, thereby realizing the assembly of drive shafts one by one.

[0047] A pusher cylinder 45 is also installed on the upper side of the unloading rack 42, and a clamping and flipping mechanism 46 is also provided on the worktable 1. The clamping and flipping mechanism 46 is located on one side of the unloading rack 42.
