AI Technical Summary

Technical Problem

In existing aluminum electrolytic prebaked anode crack detection, the manual application of coupling agent is uneven and easily generates air bubbles, leading to signal attenuation, focusing distortion, and Doppler error, thus affecting detection accuracy.

Method used

The device employs an adjustment mechanism within the housing, including a slide bar, a reciprocating plate, an application chamber, a sealing chamber, and an air bladder. It uses a magnetic ring to attract the device closer to the object being tested, automatically applying the coupling agent to ensure uniform thickness and avoid gaps and air bubbles.

Benefits of technology

It achieves uniform application of coupling agent, improves detection accuracy and efficiency, reduces false judgments, and is simple, time-saving, and labor-saving to operate.
