[0002] CCD (Charge-Coupled Device) inspection of motor rotors and stators is a high-precision inspection method that uses CCD cameras for non-contact measurement. This method is widely used in motor manufacturing and inspection, and can accurately measure and evaluate various parameters of motor rotors and stators. CCD inspection of motor rotors mainly focuses on defects such as surface cracks, shape deformation, and thickness compliance.

[0003] For example, the CCD automatic detection device recorded in the patent announcement number CN216880494U realizes the movement of the handling block in the horizontal plane and the vertical plane through the cooperation of the rotating component and the lifting component; the workpiece can be continuously loaded and unloaded by two suction cups, thereby improving the handling efficiency of the workpiece; and the automatic detection of the workpiece is realized by setting a size detection device to ensure the accuracy of size detection.
