Abstract

The invention provides an X-ray detector applied to impurity detection. The detector comprises a conveyor line, double light source X-ray scanning equipment and information processing equipment, wherein the conveyor line is used for conveying detected articles; the double light source X-ray scanning equipment is used for generating two X rays for scanning the detected articles; the two X rays form a ray included angle; and the information processing equipment is connected with the double light source X-ray scanning equipment and is used for processing the information obtained after scanning of the double light source X-ray scanning equipment to form images. The X-ray detector based on double light sources can generate X-ray double light sources so as to project the detected articles in two directions to form two complementary X-ray detecting images, thus solving the intrinsic blind zone problem of the single light source detectors and improving the impurity detection accuracy rate.

Description

technical field [0001] The invention relates to a foreign matter detection device, in particular to an X-ray detection device applied to foreign matter detection. Background technique [0002] In the prior art, in order to prevent defective products from being shipped due to foreign matter mixed into the product and damage to the product on the product production line, X-ray inspection devices are usually used to inspect the product (such as food boxes or food cans) for defective products . In the above-mentioned radiation detection device, X-rays are irradiated to the inspected object continuously conveyed on the conveying line, and the transmission state of the X-rays is detected by the X-ray light receiving part, so as to determine whether or not the inspected object is mixed with X-rays. There are foreign objects. [0003] Currently known X-ray detection devices used in the food industry are traditional single-source X-ray detection devices, that is, only a single set ...
