Background

The X-ray detection equipment is widely applied to the fields of food, medical detection, industrial inspection and the like, and the principle of industrially utilizing X-ray detection is as follows: when X-rays are absorbed by a substance, the molecules that make up the substance are broken down into positive and negative ions, known as ionization, and the number of ions is proportional to the amount of X-rays absorbed by the substance. The ionization effect is generated by air or other substances, and the ionization degree is measured by a meter, so that the quantity of the X-ray can be calculated. The image is converted into digital signals by an imager, and the digital signals are restored into images by computer-aided software to be subjected to image judgment, labeling, storage and the like.

In the existing X-ray detection equipment, when a workpiece is detected under a light source, the position of the workpiece to be detected is generally adjusted and moved for multiple times to achieve the purpose of positioning, and if the workpiece to be detected is too large and too heavy, incomplete detection due to moving inconvenience occurs, or detection is directly unavailable, so that the requirements of customers are difficult to meet.
