AI Technical Summary

Technical Problem

Traditional billboard appearance inspection relies on manual visual inspection, which is inefficient and easily leads to eye fatigue, making it difficult to effectively detect the geometry and surface damage after welding.

Method used

Design a post-weld inspection mechanism for billboards, comprising a displacement mechanism, an inspection mechanism, a material discharge assembly, and a cleaning assembly. Utilize components such as a camera, a straightness measurement assembly, a roller brush, and a cleaning roller to achieve automated inspection and cleaning, adapting to different billboard frame sizes and shapes.

Benefits of technology

It improves inspection efficiency, reduces human fatigue, can accurately detect welding angles and surface scratches, keeps the billboard frame clean, facilitates precise inspection, and avoids deformation caused by welding angle deviations.

Abstract

The application belongs to the technical field of advertising board welding detection, in particular to a post-welding detection mechanism for advertising board, which comprises an advertising board frame and further comprises a shifting mechanism arranged above the advertising board frame and a detection mechanism installed at the bottom of the shifting mechanism, the detection mechanism comprising a sliding way and a moving block installed on the sliding way, and a material discharging assembly and a cleaning assembly symmetrically arranged below the moving block, the application sets the detection mechanism to make the cleaning assembly close to the upper surface and two side surfaces of the supporting rod and clean them, the material discharging assembly discharges the sundries to the outside, so that the surface to be detected can be directly below the camera, whether there are scratches or welds on the surface of the advertising board frame after simple cleaning is easier to be observed by shooting, which avoids the influence of judgment caused by sundries covering, and the mechanism can adaptively clean the supporting rods of different widths and lengths of the advertising board frame, and can detect different types of advertising board frames.
