AI Technical Summary

Technical Problem

In existing fuse welding technologies, the rigidity of welding parameters leads to poor adaptability, laser welding causes significant thermal damage, and the lack of real-time quality inspection results in low production efficiency and high defect rate, failing to meet the production requirements of high-precision fuses.

Method used

A laser-micro-resistance hybrid welding method is adopted, which combines a dual-band collaborative imaging system and a precision resistance meter for real-time quality detection. Welding parameters are dynamically adjusted through a mapping model to achieve adaptive parameter adjustment and thermal damage control, and the welding quality is judged in real time.

Benefits of technology

It enables high-precision welding of fuses of different specifications, reduces heat damage, improves production efficiency and consistency, reduces defect rate, and meets the production needs of high-precision fuses.
