X-ray plate blank imager and detection method

Abstract

The invention relates to an X-ray plate blank imager and a detection method. The X-ray plate blank imager comprises a device body and a detection assembly arranged in the device body. A detected piecepassing opening is formed in the lower portion of the device body. The detection assembly comprises an X-ray generator and an adjustable plate arranged below the X-ray generator. A plurality of X-raycameras are arranged on the adjustable plate at intervals, the X-ray cameras are connected in series, one side of the X-ray generator is connected with a light beam device, and the X-ray generator emits fan-shaped light through the light beam device.

Description

technical field [0001] The invention relates to the field of imaging detection, in particular to an X-ray slab imager and a detection method. Background technique [0002] The traditional detector has the following defects: 1. Every time the slippery specification method needs to be re-calibrated with different steel balls, it can only be traced back to the number of alarms and cannot reverse the image. It can only detect metals and cannot classify and judge foreign objects. Foreign body area detection. 2. The horizontal density is measured by moving left and right, but the horizontal real-time performance is poor, and the vertical density change cannot be provided. 3. Regular monitoring is adopted. After an alarm occurs, modify the setting parameters according to the electronic control PLC, debug and optimize, and complete the alarm elimination and normal production. It takes half an hour or more to complete the correction. [0003] Because the traditional detector uses l...

Problems solved by technology

[0002] The traditional detector has the following defects: 1. Every time the slippery specification method needs to be re-calibrated with different steel balls, it can only be traced back to the number of alarms and cannot reverse the image. It can only detect metals and cannot classify and judge foreign objects. Foreign object area detection

2. Measure the horizontal density by moving left and right, but the horizontal real-time performance is poor, and the vertical density change cannot be provided

[0003] Because the traditional detector uses left and right moving scanning (spot X-ray method) to measure the transverse density, the real-time performance is poor, and it cannot provide the longitudinal density change; the regular observation and monitoring adopted by the traditional detector is cumbersome to operate, and it needs to be detected according to the electric current after the alarm occurs. It usually takes half an hour or more to correct the PLC, modify the setting parameters, debug and optimize, complete the alarm elimination and normal production; the traditional metal detector needs to be re-calibrated with different steel balls every time the specification is changed, and only It can detect metal, and only the number of alarms can be traced back

In order to solve a series of cumbersome matters brought by traditional detectors and increase work efficiency, the X-ray slab imager was invented
