A detection device and an X-ray leak detection method

Abstract

The invention provides a detection device and an X-ray leakage detection method. When an object to be detected is detected, the first X-ray radiation dose at the entrance of the detection device and / or at the exit of the detection device is monitored; when the first X-ray When the radiation dose is abnormal, stop emitting X-rays to detect the object to be inspected and / or issue an alarm message of X-ray leakage; when the first X-ray radiation dose is normal, start to detect the next object to be inspected. The present invention compares the X-ray radiation dose value obtained at the exit and entrance of the detection equipment with the maximum X-ray radiation dose value and the safety threshold allowed at the exit and entrance, and combines the imaging situation of the object to be inspected through the X-ray beam to determine the X-ray radiation dose. X-ray radiation is abnormal, so as to judge whether the curtains installed at both ends of the detection channel are lifted abnormally, and then shut down and give an alarm to prevent X-ray leakage, and remind the staff to carry out maintenance in time.

Description

technical field [0001] The invention relates to the technical field of X-ray leakage detection, in particular to a detection device and an X-ray leakage detection method. Background technique [0002] At present, X-ray technology is widely used in the field of online inspection of industrial production lines. Through X-ray transmission images, the internal structure and state of products can be clearly seen, and possible foreign objects or defects in products can be found. [0003] X-ray foreign matter detection equipment is divided into two categories: online and offline. Among them, the online detection equipment has a detection channel and a conveyor, and the detection channel is generally connected with the industrial production line, and the conveyor in the detection channel transports the object to be inspected It is automatically sent into the detection channel, and then automatically detected by the equipment. After the detection is completed, it is automatically sen...

Problems solved by technology

However, there are also extreme cases where the object to be inspected blocks the door curtain so that it cannot be closed automatically, the door curtain is damaged, or the maintenance personnel forget to install the door curtain. At this time, there is a safety hazard of X-ray leakage.

Traditional on-line X-ray foreign object detection equipment can only use X-rays for imaging detection of the object to be inspected, but cannot monitor X-ray leakage outside the detection channel
