360-degree plane 3D detection system and detection method based on X-RAY

Abstract

The application relates to the technical field of X-ray application equipment. The invention in particular relates to a 360-degree plane 3D detection method and detection system based on X-RAY. The detection system comprises a machine shell, an X-ray emitting device, an image receiving device and a computer processing device. The computer processing device is connected with the image receiving device, the machine shell is provided with a workbench, the X-ray emitting device and the image receiving device are arranged in the machine shell at intervals in a vertical direction, and the X-ray emitting device is used for emitting X-rays towards the image receiving device; the workbench is arranged between the X-ray emitting device and the image receiving device. The system further comprises a first driving device and a second driving device, and the first driving device is used for driving the image receiving device to move horizontally so that the image receiving device can rotate around the vertical projection of the emission center of the X-ray emission device in the direction parallel to the plane of the workbench. The system is stable in structure, and can achieve the good recognition of the internal defects of a product.

Description

technical field [0001] The present application relates to the technical field of X-ray application equipment, in particular to an X-RAY-based 360-degree plane 3D detection system and detection method. Background technique [0002] In recent years, with the rapid development of the electronics industry, the printed circuit board (referred to as PCB) industry has shown a continuous and rapid growth trend. The quality of PCB directly depends on the quality of each line and each hole on the circuit board. There are usually thousands of lines and holes on a circuit board. If any of them has quality problems such as too thin, too thick, incomplete, pinholes, adhesion, disconnection, and misalignment, it will affect the final product quality. , so PCB detection is particularly important. [0003] At present, X-RAY detection system is usually used for PCB detection, mainly including supporting table, X-ray emitting device, image receiving device and computer processing device. The...

Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that when targeting complex products, the image received by the image receiving device tends to have too much gray, which will lead to a poor simulation effect of the image by the computer processing device, thereby affecting the internal defects of the product. recognition accuracy
