Technical Field
[0001] This utility model relates to the technical field of steel mesh inspection equipment, specifically an image acquisition device for steel mesh inspection. Background Technology
[0002] In railway engineering construction, the widespread use of simply supported box girder structures has made steel mesh a key supporting skeleton material. These steel meshes are usually processed, arranged, and tied manually, a process that is not only time-consuming and labor-intensive but also highly dependent on the operator's skills. Therefore, using automated steel mesh welding equipment for production has become a necessary means to solve this problem. Furthermore, the quality inspection of large steel meshes is crucial. Traditional inspection methods mostly rely on manual visual inspection, which is not only inefficient but also easily affected by human factors, leading to inaccurate inspection results. With the advancement of technology, although some automated inspection equipment has emerged, image acquisition of ultra-large steel meshes still faces problems such as high equipment complexity, inconvenient operation, and low acquisition efficiency. To address this, we propose an image acquisition device for steel mesh inspection. Utility Model Content
