[0002] The line-tracking deviation correction inductor is applied in the coil processing industry to track and detect materials such as coating and printing edges, and feedback their position signals to a deviation correction or third-party controller, providing a position control reference for process processing or giving early warnings.

[0003] Currently, edge-tracking deviation correction inductors generally use the principles of ultrasonic waves or infrared light to track the edges of materials, while line-tracking deviation correction inductors generally adopt the principles of optoelectronics or line-scan cameras for development. The optoelectronic principle mainly uses silicon photodiode elements. The color components of the material pattern position in the sensor's field of view are different, and electrical signals are generated through the light intensity reflected by different colors to indicate the target position. The line-scan camera scans a one-dimensional linear image in real time and identifies the pattern edges.

[0004] With the development of production processes, more and more new materials and processes have been applied in production, and the products faced by machines are becoming more and more challenging.
