Description

TECHNICAL FIELD

[0001] The present application relates to the field of motor manufacturing, in particular to a magnetic shoe and shell gluing and assembling equipment. BACKGROUND

[0002] The magnetic shoe of the motor stator is usually bonded with a heat-cured glue, such as epoxy structural glue, hot melt glue, acrylic structural glue, and polyurethane glue, etc. Such glue usually has excellent bonding strength, high temperature resistance, and good environmental adaptability, to ensure that the magnetic shoe does not loosen or fall off during operation of the motor.

[0003] The conventional magnetic shoe and stator assembly structure can refer to the magnetic shoe shell assembly equipment disclosed in the Chinese patent with publication number CN116317387A. The equipment includes a warehouse structure, a gluing device, a ferromagnetic device, and a magnetic shoe pushing device. The ferromagnetic device includes a rotating assembly and a magnetic shoe pressing mold. The rotating assembly drives the magnetic shoe pressing mold and the shell to rotate. The magnetic shoe pushing device includes a transfer assembly, a magnetic shoe pushing assembly, and a magnetic shoe pushing mold. The transfer assembly is arranged between the gluing device and the ferromagnetic device. The transfer assembly transfers the glued magnetic shoe to one side of the ferromagnetic device. The magnetic shoe pushing mold extends into the inside of the shell. The outside of the magnetic shoe pushing mold is an arc-shaped guide surface. The magnetic shoe pushing assembly pushes the magnetic shoe located in the transfer assembly into the inside of the shell. The magnetic shoe is guided by the arc-shaped guide surface to enter the inside of the shell and directly adhere to the inner wall of the shell.

[0004] The process of pushing the magnetic shoe into the shell by the magnetic shoe pushing assembly is a straight-line motion. The magnetic shoe and the inside of the shell must be in close contact, which will inevitably cause glue scraping. If the amount of glue applied is too small, although the degree of glue scraping can be reduced, the problem of partial non-adhesion will further occur. Not only will there be a little glue scraping on the outside of the magnetic shoe and the problem of glue overflow, but also the problem of poor adhesion stability due to the lack of glue in some areas will occur. In subsequent use, the problems of magnetic shoe loosening and glue overflow falling off will occur, which will interfere with the operation of the rotor and seriously affect the service life of the motor. If the amount of glue applied is sufficient, the degree of glue scraping will be increased. During assembly, there will be the problem of thin glue on the bottom and thick glue on the top, which will cause errors in the adhesion of the magnetic shoe. The distance between the adhesively attached magnetic shoe and the rotor is not equal. The rotor cannot be assembled or the assembly precision is poor. There is too much glue overflow at the end, which further increases the risk of subsequent falling off. SUMMARY
