Description

Technical Field

[0001] The utility model relates to the technical field of assembly devices, in particular to an assembly device for a motor magnetic ring. Background Art

[0002] In the field of motor manufacturing, the assembly of magnetic rings is a crucial link. The motor magnetic ring is usually composed of an iron ring and a magnetic strip ring. The magnetic strip ring is formed by extruding and bending the strip magnetic strips and connecting them end to end to form a circular ring structure. The magnetic ring is a ring-shaped magnetic conductor, usually made of ferrite materials (such as Mn-Zn), which has a good inhibitory effect on high-frequency noise. As part of the motor rotor, the magnetic ring not only affects the performance parameters of the motor, but is also directly related to the overall operating efficiency and stability of the motor. Through the automated assembly device, the magnetic ring can be accurately positioned and fixed, effectively improving the assembly accuracy and reducing human errors.

The second cylinder 21 drives the connecting plate 22 to move, so that the rotating head 14 is located at the lower end of the feeding component 11, so that the rotating head 14 contacts with the magnetic ring, and the second The servo motor 17 is started, and the gear 16 is used to transmit the rotation to the rotating head 14 to drive the magnetic ring to rotate and dock, ensuring that the magnetic ring is correctly docked with the rotor core 6. After the rotation and docking are completed, the rotating plate 7 continues to rotate and brings the forming plate 8 to the bottom of multiple dispensing components 10. The dispensing components 10 sequentially dispense glue at different positions of the connection between the rotor core 6 and the magnetic ring to strengthen the connection strength. The forming plate 8 rotates to the bottom of the riveting component 9, and the third cylinder 25 drives the pressing plate 26 to press down, pressing the rotor core 6 downward to ensure the assembly accuracy of the rotor core 6 and the magnetic ring. At the same time, the fourth cylinder 28 drives the sliding frame 30 and the moving plate 27 to move, and the assembly is further supported and positioned by the support frame 33. The assembled motor magnetic ring rotates with the rotating plate 7 to the bottom of the discharge component 3, and the discharge component 3 takes out the assembled motor magnetic ring to prepare for the next round of assembly or subsequent processing.
