[0002] Nuclear fuel rods, related rods and some other nuclear products currently generally use X-ray radiography for internal defect detection, and the radiography platform is an important equipment for radiographic detection. At present, foreign countries including the United States, Germany, Japan and other countries have adopted more advanced automation equipment to realize integrated full-process automated radiography of fuel products. Domestically, the China Institute of Atomic Energy and the China Nuclear Power Research and Design Institute, etc., are mostly scientific research products with low output. They use semi-automatic methods for product layout and radiography. For production companies, large-scale radiography is required. This method is not economical and has low inspection efficiency. Since the 1980s, China National Nuclear Corporation Jianzhong Nuclear Fuel Element Co., Ltd. has built 1# and 2# fuel rod production lines, which have a high level of automation and are mainly used for the production of fuel rods; while other nuclear products such as scientific research or related components have low output, and their production equipment has a low level of automation, and most of them rely on manual labor. The X-ray radiography platform device currently used by the company has the following shortcomings:
