Description

Technical Field

[0001] This utility model relates to the field of motor processing technology, and in particular to a brushless fan motor assembly machine. Background Technology

[0002] Brushless fan motors are widely used in computer cooling, home appliances, and industrial equipment due to their high efficiency, low noise, and long lifespan. A typical brushless fan motor consists of a stator assembly (including coils and silicon steel sheets), a rotor assembly (including permanent magnets and a shaft), a housing, bearings, and a circuit board.

[0003] Traditional assembly methods often rely on manual operation or the use of multiple independent tooling fixtures to complete the pressing process step by step. Manual operation is slow, and the time-consuming transfer between processes makes it difficult to meet the needs of large-scale production, resulting in low production efficiency. Furthermore, assembly precision is inconsistent: manual pressing makes it difficult to precisely control the force and angle, easily leading to problems such as misaligned motor coils, damage to the drive shaft, and uneven assembly gaps, affecting motor performance and yield. To address these issues, a solution is proposed below. Utility Model Content

When assembling the motor, the motor housing can be placed on the upper end of the positioning shaft and positioned with the lower end of the motor housing through the positioning shaft sleeve, thereby ensuring the accuracy of the motor housing's placement. After the motor housing is placed, the two lower clamping blocks can be used to clamp and fix the two sides of the motor housing to ensure the stability of the motor assembly and further improve the accuracy of the motor assembly. The operator can place the motor coil on the upper end of the positioning plate, so that the drive shaft of the motor coil is located in the centering groove. At the same time, the positioning blocks can be used to abut and position the outer side of the motor coil, thus achieving the positioning and centering of the motor coil. After that, the operator can move the placement plate to move the motor coil above the motor housing. After the motor coil is placed, the two moving frames can be brought closer together to drive the two upper clamping blocks to bring closer together, thereby clamping and fixing the drive shaft of the motor coil to play a centering role during assembly, thereby improving the accuracy of the assembly position.

[0017] 2.

[0024] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0025] like Figures 1 to 4 As shown, a brushless fan motor assembly machine includes a machine base 1. The upper end of the machine base 1 is equipped with a moving mechanism 2, a lower clamping mechanism 3, an upper clamping mechanism 4, and a lifting mechanism 5. The moving mechanism 2 includes a motor lead screw linear module 6 mounted on the upper end of the machine base 1. A movable lead screw seat 7 is threadedly connected to the motor lead screw linear module 6. The motor lead screw linear module 6 can drive the lead screw seat 7 to move left and right. The structure of the motor lead screw linear module 6 is existing technology; it is essentially a motor-driven lead screw rotation, so it will not be described in detail. Two first guide rails 8 are fixedly mounted on the upper end of the machine base 1. Several slidable first guide blocks 9 are embedded in the two first guide rails 8. A base plate 10 is fixedly mounted on the upper end of the several first guide blocks 9, and the lead screw seat 7 is fixedly connected to one side of the base plate 10. The left and right movement of the lead screw seat 7 can drive the base plate 10 to move left and right, thereby causing the several first guide blocks 9 to slide left and right along the two first guide rails 8 respectively. A positioning shaft 11 is rotatably connected to the upper end of the base plate 10. A positioning sleeve 12 is connected to the positioning shaft 11, and a motor housing 13 is placed on the upper end of the positioning sleeve 12. When assembling the motor, the motor housing 13 can be placed on the upper end of the positioning shaft 11, and the positioning shaft 11 is fitted with the lower end of the motor housing 13 for positioning, thereby ensuring the accuracy of the placement of the motor housing 13.

[0026] The lower clamping mechanism 3 includes two lower clamping blocks 14. After the motor housing 13 is placed, the two lower clamping blocks 14 can clamp and fix both sides of the motor housing 13 to ensure the stability of the motor assembly and further improve the accuracy of the motor assembly. The upper end of the base plate 10 is fixed with two second guide rails 15. Each second guide rail 15 is embedded with two slidable second guide blocks 16. The upper end of each pair of second guide blocks 16 is connected to a moving plate 17. The upper end of each of the two moving plates 17 is fixed with several connecting posts 18. The two lower clamping blocks 14 are fixedly connected to several connecting posts 18. When the moving plate 17 moves, it can drive the two lower second guide blocks 16 to slide along the second guide rails 15, and at the same time drive the upper connecting posts 18 to move. Finally, it can drive the two lower clamping blocks 14 to move at the same time, so as to adjust the distance between the two lower clamping blocks 14. Two second guide blocks 16 are connected to first racks 19. A first gear 20 is fixed on the outer side of the positioning shaft 11. The two first racks 19 mesh with the first gear 20 respectively. A first electric cylinder 21 is installed at the lower end of one of the moving plates 17. The output shaft of the first electric cylinder 21 is connected to the lower side of the other moving plate 17. When the output shaft of the first electric cylinder 21 extends outward, it can drive the right moving plate 17 to move to the right. At this time, it can drive the lower first rack 19 to move to the right, thereby driving the first gear 20 to rotate. Since the two first racks 19 mesh with the first gear 20 respectively, the upper first rack 19 can move to the left as the first gear 20 rotates, thereby driving the left moving plate 17 to move to the left. Finally, the two moving plates 17 can be moved away from each other, thereby moving the two lower clamping blocks 14 away from each other. Conversely, when the output shaft of the first electric cylinder 21 retracts inward, the two lower clamping blocks 14 move closer to each other.

[0027] The upper end of the machine base 1 is also provided with a support frame 38 and a fixed frame 39. The upper end of the support frame 38 and one side of the fixed frame 39 are respectively fixed with a fifth guide rail 40. Several slidable fifth guide blocks 41 are embedded on the two fifth guide rails 40. The upper end of several fifth guide blocks 41 is connected to a placement plate 42. The upper end of the placement plate 42 is connected to a vertical plate 43. The vertical plate 43 is fixedly connected to the other fifth guide blocks 41. By pushing the placement plate 42 back and forth, the vertical plate 43 can be moved back and forth, thereby causing several fifth guide blocks 41 to slide back and forth along the two first guide rails 8 respectively. A positioning plate 44 is fixedly provided on the upper end of the placement plate 42. A motor coil 37 is placed on the positioning plate 44. A centering groove 45 is provided on the positioning plate 44. A positioning block 46 is also fixedly provided on the upper end of the positioning plate 44. The operator can place the motor coil 37 on the upper end of the positioning plate 44, so that the drive shaft of the motor coil 37 is located in the centering groove 45. At the same time, the positioning block 46 can be used to abut and position the outer side of the motor coil 37. Finally, the motor coil 37 can be positioned and centered. Then the operator can move the placement plate 42 to move the motor coil 37 above the motor housing 13.

[0028] The upper clamping mechanism 4 includes two upper clamping blocks 22. A bracket 23 is fixedly installed at the upper end of the machine base 1. Two third guide rails 24 are fixedly installed on one side of the bracket 23. Several slidable third guide blocks 25 are embedded on the two third guide rails 24 respectively. A mounting plate 26 is connected to one side of the several third guide blocks 25. When the mounting plate 26 moves up and down, it can drive the several third guide blocks 25 to slide up and down along the two third guide rails 24 respectively. A connecting plate 27 is fixedly mounted on one side of the mounting plate 26. Two fourth guide rails 28 are fixedly mounted on one side of the connecting plate 27. Two slidable fourth guide blocks 29 are embedded in each fourth guide rail 28. A movable frame 30 is connected to each pair of fourth guide blocks 29, and two upper clamping blocks 22 are fixedly mounted on the inner side of the two movable frames 30. A second electric cylinder 31 is mounted on one side of the mounting plate 26, and the output shaft of the second electric cylinder 31 is fixedly connected to one side of the movable frame 30. A second gear 32 is rotatably connected to the connecting plate 27. A second rack 33 is fixedly mounted on the bottom of each of the two movable frames 30. The two second racks 33 mesh with the second gear 32 respectively. When the output shaft of the second electric cylinder 31 extends... The second electric cylinder 31 can move the left movable frame 30 to the right, thereby moving the connected second rack 33 to the right. This causes the second gear 32 to rotate. Since the two second racks 33 mesh with the second gear 32, the rotation of the second gear 32 can move the other second rack 33, that is, the other second rack 33 can move to the left. This will eventually move the right movable frame 30 to the left. At this time, the two movable frames 30 move closer to each other, which will cause the two upper clamping blocks 22 to move closer to each other. Conversely, when the output axis of the second electric cylinder 31 retracts inward, the two upper clamping blocks 22 move away from each other, which will eventually adjust the distance between the two upper clamping blocks 22.

[0029] When the two movable frames 30 move, they can also drive several fourth guide blocks 29 to slide along the two fourth guide rails 28 respectively. After the motor coil 37 is placed, the two movable frames 30 can move closer to each other, thereby driving the two upper clamping blocks 22 to move closer to each other, thus clamping and fixing the drive shaft of the motor coil 37, so as to play a centering role during assembly and thus improve the accuracy of the assembly position.

[0030] The lifting mechanism 5 includes a third electric cylinder 34 on the top of the mounting bracket 23. A lifting plate 35 is also fixedly mounted on one side of the mounting plate 26, and the output shaft of the third electric cylinder 34 is fixedly connected to the lifting plate 35. A positioning head 36 is connected to the lifting plate 35. A motor coil 37 is clamped between two upper clamping blocks 22, and the top end of the motor coil 37 abuts against the positioning head 36. The output shaft of the third electric cylinder 34 can drive the lifting plate 35 to move up and down, thereby driving the mounting plate 26 to move up and down, and simultaneously driving the connecting plate 27 to move up and down. When the motor coil 37 is clamped and fixed, the top end of its drive shaft can be... The positioning head 36 abuts against each other, which further positions the motor coil 37. Then, the placement plate 42 can be pushed to separate the positioning plate 44 from the motor coil 37. Subsequently, the lifting plate 35 can move downward to drive the fixed and clamped motor coil 37 downward. Finally, the motor coil 37 can be installed into the motor housing 13 to complete the assembly between the motor housing 13 and the motor coil 37. By clamping and fixing the motor housing 13, and simultaneously clamping, fixing and centering the motor coil 37, the accuracy after assembly can be guaranteed, which can further improve the practicality of the device.

[0031] A top plate 47 is connected above the machine base 1. A fourth electric cylinder 48 is installed on the top plate 47, and a pressure block 49 is located below the top plate 47. The output shaft of the fourth electric cylinder 48 is fixedly connected to the upper end of the pressure block 49. After assembly, the motor housing 13 can be moved to the lower end of the pressure block 49 by the movement of the base plate 10. Then, the end cover can be placed on the upper end of the motor housing 13, and the pressure block 49 can be moved downward by the output shaft of the fourth electric cylinder 48, thereby pressing the end cover into the motor housing 13 to complete the assembly of the motor. Two guide sleeves 54 are fixedly installed on the top plate 47. Sliding guide shafts 55 are respectively inserted into the two guide sleeves 54. The lower ends of the two guide shafts 55 are fixedly connected to the upper end of the pressure block 49. When the pressure block 49 moves up and down, it can drive the two guide shafts 55 to slide up and down along the two guide sleeves 54 at the same time. Therefore, the movement trajectory of the pressure block 49 is straighter and more stable, which further ensures the accuracy of motor assembly.

[0032] A handwheel threaded rod module 50 is installed on the upper end of the machine base 1. A threaded seat 51 is connected to the handwheel threaded rod module 50, and an adjusting plate 52 is connected to the upper end of the threaded seat 51. A laser marking device 53 is installed on the adjusting plate 52. By adjusting the handwheel threaded rod module 50, the threaded seat 51 can be moved up and down along the handwheel threaded rod module 50, thereby moving the adjusting plate 52 up and down, and finally moving the laser marking device 53 up and down. Therefore, the height position of the laser marking device 53 can be adjusted. When the assembled motor moves in front of the laser marking device 53, the laser marking device 53 can be used to mark the surface of the motor housing 13 for further processing. The structure of the handwheel threaded rod module 50 is existing technology; it is essentially a handwheel driving the threaded rod to rotate. The model, structure, and working method of the laser marking device 53 are also existing technology, so they will not be described in detail.
