AI Technical Summary

Technical Problem

In existing technologies, the detection of surface defects in fiberglass products relies on manual visual inspection, especially the problem of cavitation, which is difficult to detect, resulting in low detection efficiency and poor quality.

Method used

Design an automated inspection device that includes positioning, conveying, and inspection mechanisms. The positioning mechanism automatically positions the rail transit fairing, the conveying mechanism automatically conveys it, and the inspection mechanism uses inspection probes to perform comprehensive inspection and detect defects that are not visible to the naked eye.

Benefits of technology

It has enabled automated detection of surface defects in fiberglass products, improved detection efficiency, reduced manual labor time, significantly improved surface quality, and provided a good guarantee for subsequent painting.

Abstract

This invention discloses a surface defect detection device for rail transit fairings, relating to the technical field of rail transit fairing manufacturing. It includes an installation platform, a positioning mechanism, a conveying mechanism, and a detection mechanism. The positioning mechanism comprises a pair symmetrically arranged on the left and right sides of the installation platform, used for automatically positioning the rail transit fairing to be inspected, and includes a hydraulic cylinder, a positioning plate, and a positioning block. The conveying mechanism comprises a pair symmetrically arranged on the left and right sides of the installation platform, used for automatically conveying the rail transit fairing before and after inspection, and includes a first fixing plate, a first motor, and a support plate. The detection mechanism is located above the installation platform and is used for automatically and comprehensively inspecting the surface of the positioned rail transit fairing for cavitation defects. The detection mechanism includes a second fixing plate, a second motor, a threaded rod, a third fixing plate, a third motor, a mounting rod, and a detection probe. This invention features high efficiency and accuracy in detection.
