Description

Technical Field

[0001] The present invention relates to the field of detection technology, and in particular to an X-ray detection stepping device and a detection method for a plate-fin radiator. Background Art

[0002] The plate-fin radiator core is the core component of the main heat exchange equipment in the aviation heat exchanger. The quality of the plate-fin radiator core directly affects the performance of the heat exchanger. During the production process of the plate-fin radiator, each set of products needs to be X-rayed after the life test to check the production quality of the radiator core, which is a key process. The main inspection contents include whether the fins of the radiator core are deformed, defective, and whether there are foreign objects.

[0003] At present, when the plate-fin radiator core is X-rayed, due to the hazards of X-ray radiation, each time a layer is inspected, the staff enters the inspection room to manually adjust it and then comes out to inspect it, repeating the work until all inspections are completed. Since the shooting distance during the inspection is manually adjusted, it is impossible to ensure that it is equidistant and consistent with the core spacing, and the inspection results often have repeated shots or missed shots. And when a machine fails, it cannot be inspected on the machine, and the product must be dismantled and sent back to the original site for inspection.

[0004] According to statistics, each set of products uses more than 40 X-ray inspection films, which takes up one working day of the X-ray detection equipment and film developing equipment. When this type of product is being X-ray inspected, the other products are waiting in that process, disrupting the production rhythm of the other products that need X-ray inspection and affecting subsequent processes. The X-ray inspection process has become a bottleneck process in the production process of radiator products. Summary of the invention
