[0002] In the production process of flat wire motor stators, the wire forming equipment is a key link. The quality of its wire output directly affects the implementation of subsequent processes such as wire pressing, flaring, and twisting, and thus determines the overall quality of the stator.

[0003] Traditional manual measurement methods have many problems: First, copper wire itself is relatively soft, and direct manual measurement can easily deform the wire, affecting the accuracy of the measurement results; second, manual measurement is inefficient and cannot meet the needs of large-scale production; and some dimensions cannot be measured directly by hand, such as angles or the distance from a point to a line.

[0004] Furthermore, the wire forming equipment produces a wide variety of wire types. During the equipment commissioning phase, the dimensions of each wire type need to be measured to ensure consistency in the output. Existing measuring equipment has shortcomings in terms of measurement field of view, compatibility, accuracy, and efficiency, and cannot meet the requirements of rapid and accurate measurement of multiple wire types on the production line. Therefore, developing a high-efficiency, accurate, and highly compatible wire forming dimension visual measurement system is of great significance for improving the production quality and efficiency of flat wire motor stators.
