Feeding device for motor rotor magnetic shoe filling

Abstract

A feeding device for motor rotor magnetic shoe filling comprises a supporting plate, a magnetic shoe channel plate and magnets, wherein the magnetic shoe channel plate is provided with a plurality of storage channels for magnetic shoes to be arranged and is arranged on the upper end face of the supporting plate, the supporting plate is provided with a blanking channel communicated with one end of each storage channel, and magnetic shoe blanking ports corresponding to the arrangement positions of the magnetic shoes in a motor rotor are formed. The magnets are arranged in the magnetic shoe blanking ports and used for attracting the magnetic shoes in the magnetic shoe channel. Due to the fact that the magnets are fixedly arranged, N / S polarity of the magnets are not changed, the magnetic shoes suspended each time can be only in contact with the magnets in the fixed N / S pole directions, and the problem that the N / S poles of the magnetic shoes are arranged by mistake does not occur. Multiple magnetic shoes can be accurately installed by adopting the feeding device in one time, the problem of low efficiency during manual filling and the problem that the poles of the magnetic shoes are easily mistakenly arranged are solved simultaneously, and working efficiency is improved.

Description

technical field [0001] The invention relates to the field of rotor manufacturing equipment, in particular to a feeding device for filling magnetic tiles of motor rotors. Background technique [0002] In brushless DC motors, the existing installation methods of magnetic components are: [0003] 1) Glue fixing: However, it is not easy to apply glue evenly by hand, it is not environmentally friendly, the heat-setting time is long, the production efficiency is low, and there is a hidden danger of falling off and jamming the motor in future use. [0004] 2) Fixed by the slot of the fixed bracket: but the magnetic tile requires high dimensional accuracy to fix the magnetic tile firmly, otherwise it may not be installed or loose, which will increase the production cost. [0005] The above installation method makes the outer diameter of the rotor fluctuate widely, resulting in an asymmetric air gap of the motor, which in turn causes the motor to vibrate greatly during operation, ca...

Problems solved by technology

[0003] 1) Glue fixation: But it is not easy to apply glue evenly by hand, it is not environmentally friendly, the heat-setting time is long, the production efficiency is low, and there is a hidden danger of falling off and jamming the motor in future use

[0004] 2) Use the fixed bracket card slot to fix: but the magnetic tile requires high dimensional accuracy, so that the magnetic tile can be firmly fixed, otherwise there will be a phenomenon that the installation cannot be inserted or loosened, and the production cost will be high.

When using this process to process the rotor, workers need to put the magnetic tiles into the injection mold according to the correct N\S position, the feeding efficiency is low, and the error rate of N\S position reversal is high, which seriously affects the processing efficiency
