Description

Technical Field

[0001] The present application relates to the field of rotor balancing correction, and in particular to a transport mechanism for rotor balancing correction. Background Art

[0002] The motor rotor is a rotating part in the motor, which is used to cooperate with the motor stator to realize the conversion of electrical energy and mechanical energy. Since the motor rotor is affected by the materials, manufacturing process and assembly process during its manufacturing process, it has an initial imbalance. If the initial imbalance of the motor rotor is too large, it will produce great vibration and noise when rotating at high speed, which not only affects the normal use of the motor, but also greatly shortens the service life of the motor. Based on this, after the motor rotor is processed, workers usually use a motor rotor balancing machine to detect and correct the imbalance of the motor rotor to ensure product quality.

[0003] After the rotor balancing test is completed, the rotor usually needs to be transported to the calibration station for balancing correction. In the prior art, the rotor is usually transported by a single manipulator. However, since there is usually a certain distance between the rotor testing station and the rotor calibration station, the manipulator needs to move a long distance to complete the rotor transportation, and the transportation efficiency is low.

After the rotor is inspected at the inspection station, the first manipulator 2 grabs the rotor from the inspection station to the transfer seat 7, and then the second manipulator 5 grabs the rotor from the transfer seat 7 to the correction station. With the connection and cooperation of the first manipulator 2, the second manipulator 5 and the transfer seat 7, the handling stroke of a single manipulator can be effectively shortened, and the handling efficiency can be improved.
