Description

Technical Field

[0001] This invention relates to the field of motor quality inspection technology, and in particular to a machine vision-based motor stator winding assembly quality inspection device. Background Technology

[0002] Electric motors are used in many fields and play a vital role in daily life and production. An electric motor mainly consists of a stator and a rotor. The stator primarily generates a magnetic field, while the rotor cuts magnetic lines of force within the rotating magnetic field to generate current. The stator is a crucial component of the motor, significantly impacting its performance. Furthermore, the quality of the stator is critical to the motor's safety. Since motors require 220V AC power during operation, issues such as leakage, burnout, and fires frequently occur. Therefore, the stator windings are extremely important to prevent safety hazards. During motor production, the assembled stator windings need to be inspected to prevent quality defects. Therefore, a machine vision-based quality inspection device for motor stator winding assembly is designed.
