The transformer core is the core component of the transformer, and its shape and processing accuracy play a decisive role in the magnetic properties and measurement accuracy of the transformer. The traditional transformer core processing method has the following shortcomings: manual operation is difficult to ensure smooth cutting edges, the manual adjustment of the cutting head cannot meet the needs of mass production, and there is a serious waste of materials and insufficient intelligence in the process.

[0003] In order to solve these problems, this application proposes a machine vision-based transformer core cutting device, which realizes efficient, accurate and low-consumption processing of core materials through visual guidance technology, high-precision cutting equipment and intelligent multi-module collaborative control.
