Abstract：To address the issues of low efficiency,significant errors,and inaccurate classification in traditional inspection methods for liquid-filled formed equilateral triangular tubes,an intelligent detection device based on angle determination was developed.The device determines whether the internal angle of the tube is 60° through an error identification mechanism.It achieves energy self-sufficiency by combining magnetic field cutting power generation with the triboelectric-piezoelectric effect,while a multi-level marking mechanism classifies and labels defective products.The experiments?indicated demonstrate that the device achieves high accuracy in inspecting tubes of varying specifications,with significantly shorter detection time compared to traditional methods,thereby improving inspection efficiency.Its application in aerospace and automotive manufacturing has notably reduced production costs,while providing an innovative solution for the efficient inspection of liquid-filled formed tubes.
