AI Technical Summary

Technical Problem

The existing permanent magnet motor rotor magnet assembly is inefficient and has poor precision consistency. Manual operation is prone to errors and cannot meet the needs of mass production.

Method used

Assembly equipment is used, including assembly fixtures, brackets with slots, and flexible tracks. Magnets are fixed on the flexible tracks using foolproof magnets. Multiple magnets are fed, positioned, and transferred synchronously through the flexible tracks. Combined with upper and lower fixtures, the accurate positioning and correct polarity of the magnets are ensured.

Benefits of technology

Significantly improves assembly efficiency, ensures consistent magnet spacing and correct polarity, reduces operational difficulty and training costs, and enhances production efficiency and motor performance.

Abstract

The invention provides an assembling method for a rotor magnet of a permanent magnet motor, and relates to assembling equipment which comprises an assembling jig, a bracket provided with a clamping groove, a flexible track and a plurality of fool-proof magnets, the assembling method comprises the steps that S1, a plurality of assembling magnets coated with an accelerant are attracted and fixed to fool-proof magnets corresponding to the flexible track in the mode that opposite magnetic poles are opposite, and when each assembling magnet is attracted to the corresponding fool-proof magnet, the flexible track is synchronously pushed into a clamping groove; s2, the stator iron ring coated with the glue is fixed in an assembling jig; s3, the flexible crawler belt is pulled out of the clamping groove, and the assembly magnet moves along with the flexible crawler belt under the adsorption effect of the fool-proof magnet and is kept fixed; s4, when the flexible crawler belt is pulled out, the flexible crawler belt is synchronously wound to the periphery of the stator iron ring, so that the assembled magnet is aligned to a preset mounting position on the stator iron ring; and S5, the assembled magnet is pressed into the stator iron ring, and bonding assembly is completed. According to the invention, the efficiency and precision of magnet assembly can be improved.
