[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0018] As Figures 1-6 shown, the present utility model provides an automatic screw assembly device for a motor, including a workbench 1. A indexing turntable 2 is installed on the upper side of the workbench 1. A plurality of assembly positioning seats 14 are evenly arranged around the circumference on the upper side of the indexing turntable 2. A front bracket loading manipulator 7 is arranged on one side of the indexing turntable 2. The front bracket loading manipulator 7 is docked with a front bracket conveying device 5 on one side of the workbench 1 to place the front bracket on the assembly positioning seat 14. A main and auxiliary stator feeding conveyor line 3 is arranged on the side of the indexing turntable 2. A main and auxiliary stator feeding assembly 4 is arranged between the main and auxiliary stator feeding conveyor line 3 and the indexing turntable 2 to sequentially place the main and auxiliary stators on the front brackets on the assembly positioning seats 14. An automatic screw driving assembly 6 is also arranged on the side of the indexing turntable 2. The automatic screw driving assembly 6 is connected to a screw conveying assembly 13 on the upper side of the workbench 1 to connect and fix the main and auxiliary stators and the front brackets. At least one automatic tapping assembly 11 is sequentially installed along the indexing turntable 2 on the side of the automatic screw driving assembly 6. An automatic unloading manipulator 10 is arranged along the indexing turntable 2 on the side of the automatic tapping assembly 11. A blanking conveyor belt is arranged under the automatic unloading manipulator 10.

[0019] Specifically, the front bracket conveying device 5 includes a front bracket conveying vibrating disk and a corresponding conveying track. The front brackets will be conveyed one by one to the end of the conveying track, and then the front bracket loading manipulator 7 places the front brackets on the assembly positioning seats 14 for positioning. The structure and shape of the assembly positioning seats 14 need to be designed according to the specific structural dimensions of the front brackets and the main and auxiliary stators. It only needs to ensure that the two components can be firmly positioned and there is enough space for the manipulator to pick up. The front bracket loading manipulator 7 adopts a conventional manipulator, generally including a horizontal moving component and a vertical moving component, which can realize the lifting and horizontal movement of the product. These are standard components on the market and can be easily realized.

[0020] The front bracket on the assembly positioning seat 14 moves to the position of the main and auxiliary stator feeding assembly 4 as the indexing turntable 2 rotates. The main and auxiliary stators already assembled on the main and auxiliary stator feeding conveyor line 3 are placed on the front bracket through the main and auxiliary stator feeding assembly 4 for corresponding assembly. Then, as the indexing turntable 2 rotates, it moves to the position of the automatic screw driving assembly 6. Two screws are driven into the space between the front bracket and the main and auxiliary stators through the automatic screw driving assembly 6 to fasten the two parts together. Then, through the knocking of the automatic knocking assembly 11, the screws are assembled in place. Finally, the automatic blanking manipulator 10 is used for blanking.

[0021] In this embodiment, the automatic screw driving assembly 6 includes two screw driving units arranged side by side and capable of synchronous lifting. The screw driving unit includes a driving motor 15 and a telescopic cylinder 16 arranged on the lower spindle of the driving motor 15. A screw driving head 17 is arranged at the lower end of the telescopic cylinder 16. A conveying sleeve 19 is sleeved outside the lower part of the telescopic cylinder 16. A feed pipe 18 is arranged on one side of the conveying sleeve 19. The feed pipe 18 is connected to the screw conveying assembly 13 through a hose. The driving motor 15 can drive the telescopic cylinder 16 and the screw driving head 17 to rotate together. The screw driving unit is driven by a standard lifting assembly for lifting. At the same time, the feed pipe 18 sucks the screws on the screw conveying assembly 13 into the conveying sleeve 19, and the screw driving head 17 ejects and rotates the screws to complete the installation of the screws. There is a negative pressure suction structure on the hose to suck away the screws.

[0022] In order to enable the screw conveying assembly 13 to convey two screws simultaneously, the screw conveying assembly 13 includes a screw vibrating conveyor disk 12 and a screw positioning seat 24 arranged at the end of the screw vibrating conveyor disk 12. A positioning groove 23 is arranged on the screw positioning seat 24. A slider communicating with the screw vibrating conveyor disk 12 is arranged inside the screw positioning seat 24. Cylinders 22 connected to the slider are arranged on both sides of the screw positioning seat 24. By driving the slider to slide left and right through the cylinders 22, the screws conveyed by the screw vibrating conveyor disk 12 are successively moved to both ends of the positioning groove 23, and then the two screws are sucked away by the hose, with high efficiency.

[0023] Since the assembled main and auxiliary stators were assembled in the reverse direction in the previous process, the main and auxiliary stators need to be turned over in this process. Therefore, the feeding assembly 4 for the main and auxiliary stators includes a first manipulator assembly and a second manipulator assembly. The first manipulator assembly is used to turn over the main and auxiliary stators, and the second manipulator assembly is used to move the turned-over main and auxiliary stators to the assembly positioning seat 14. Specifically, the first manipulator assembly includes a rotary cylinder 45 installed on the lifting unit and a first clamping cylinder 46 installed on the first rotary cylinder 45. A product gripper is provided on the first clamping cylinder 46. The rotary cylinder 45 is arranged above one end of the feeding conveyor line 3 for the main and auxiliary stators. The second manipulator assembly includes a servo transverse movement unit 41 arranged above the first manipulator assembly and a lifting cylinder 42 arranged on the servo transverse movement unit 41. A second rotary cylinder 43 is installed at the lower end of the lifting cylinder 42, and a plug-in tensioning column 44 is arranged at the lower end of the second rotary cylinder 43. The plug-in tensioning column 44 is inserted into the through hole in the middle of the already turned-over main and auxiliary stators, and the main and auxiliary stators can be lifted by expanding it.

[0024] In order to automatically detect good products and defective products, a vision detection unit is arranged between the automatic knocking assembly 11 and the automatic blanking manipulator 10. The blanking conveyor belt includes a good product blanking conveyor belt 8 and a defective product blanking conveyor belt 9.
