Problems solved by technology

[0002] In the production of the motor rotor, it is necessary to stamp out the chute on the iron core. At present, it mainly depends on the human eye to judge whether the angle of the rotor chute meets the requirements. However, the manual inspection is not rigorous, resulting in frequent quality accidents of abnormal rotor chute angles.
Moreover, since the rotor is made of cast aluminum, the rotor may also have an air gap problem. Therefore, it is still necessary to manually detect the fullness of the rotor, but at present it still relies on manual detection

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a rotor aluminum strip detection device and a rotor aluminum strip detection method. Background technique [0002] In the production of motor rotors, it is necessary to punch out inclined grooves on the iron core. At present, it is mainly dependent on the human eye to judge whether the angle of the rotor inclined groove meets the requirements. However, the manual inspection is not rigorous, resulting in frequent quality accidents with abnormal rotor inclined groove angles. In addition, because the rotor is made of cast aluminum, the rotor may also have an air gap problem. Therefore, it is necessary to manually detect the fullness of the rotor, but at present, it is still manually detected. SUMMARY OF THE INVENTION [0003] One of the objectives of the present invention is to avoid the deficiencies in the prior art and provide a rotor aluminum bar detection device, which can accu...
