一种AFA3G定位格架外观自动检测装置
摘要：
本发明属于核燃料元件制造技术领域，具体涉及一种AFA3G定位格架外观自动检测装置。本发明的一种AFA3G定位格架外观自动检测装置，包括成像系统和工作台；所述成像系统安装于工作台之上。所述成像系统包括：第一相机、第二相机、第三相机、第一镜头、第二镜头和第三镜头。所述第一镜头和第二镜头为双远心镜头，所述第三镜头为小视场双远心镜头。本发明需要解决的技术问题为：现有的格架外观检查一直采用人工目视检查的方式，检测效率不高，而且容易引起检验人员视觉疲劳而出现漏检、误检。使用本发明的AFA3G定位格架外观自动检测装置，能够实现自动对定位格架的外观进行检测，检测效率高，漏检和误检率低，检测性能稳定。
摘要（英）：

The invention belongs to the technical field of nuclear fuel elements and particularly relates to an automatic appearance detection device for AFA3G spacer grid. The device comprises an imaging system and a workbench, and the imaging system is mounted above the workbench and comprises a first camera, a second camera, a third camera, a first lens, a second lens and a third lens. The first lens and the second lens are bi-telecentric lens, and the third lens is a small-view-field bi-telecentric lens. The technical problem to be solved includes that existing spacer grid appearance inspection which is always performed by means of manual visual check is low in detection efficiency and proneness to missing inspection and false inspection due to visual fatigue of inspection personnel. By application of the automatic appearance detection device for the AFA3G spacer grid, automatic appearance detection of the AFA3G spacer grid can be realized, and high detection efficiency, low missing inspection and false inspection rate and detection performance stability are realized.
