AI Technical Summary
Technical Problem
Existing automotive protective film corrosion resistance testing benches require manual cutting and spraying of corrosive liquid after testing, which increases workload, poses safety hazards, and has poor synchronization, affecting the testing results.
Method used
A testing platform comprising a reciprocating mechanism, a transverse component, and a clamping component was designed. A servo motor drives a threaded rod to achieve automated linkage between the cutting blade and the spray head, ensuring that cutting and corrosive liquid spraying are carried out synchronously.
Benefits of technology
It achieves automation and synchronization of the detection process, improves detection efficiency and accuracy, and ensures operational stability and safety.
