AI Technical Summary

Technical Problem

Existing fiber laser devices cannot detect abnormalities in a timely and accurate manner during processing, resulting in defects or damage to the workpieces. Existing data has large errors and cannot stop processing in a timely manner.

Method used

The system employs a combination of a control module, a laser generation module, a coupling device, a signal light module, a photodetector, and a processing head. Through the cooperation of the coupling device and the photodetector, it accurately detects the light to be measured. It uses the wavelength difference between the signal light and the laser to isolate them, forming accurate detection data. The control module controls the target execution component according to the threshold.

Benefits of technology

It enables real-time and precise control of fiber laser devices, reducing labor costs, ensuring processing quality, avoiding defects in workpieces, and improving processing efficiency.
