AI Technical Summary

Technical Problem

The inability to quickly determine the specific location and cause of quality abnormalities during the production process of airbags leads to low production efficiency and difficulty in guaranteeing product qualification rates.

Method used

By obtaining the current process number, retrieving work reports and tool usage information, and combining the global top view and the side view of the airbag fabric, we can analyze the undulations and texture features, distinguish between coating thickness anomalies, temporary wrinkles and permanent wrinkles, and use angle adjustment and supplementary lighting to eliminate light reflection interference, construct a texture distortion correction mechanism, and achieve accurate detection.

Benefits of technology

It enables rapid location and cause analysis of airbag quality abnormalities, improves the accuracy and efficiency of detection, reduces misjudgments, and enhances the automation level and reliability of production.
