Desktop X-ray detectorIt is a compact, high-precision non-destructive testing equipment designed specifically for laboratories and industrial sites, which uses X-ray penetration technology to visualize the internal structure of materials. Its core advantages lie in its compact size, convenient operation, and diverse functions, which can be widely used for defect detection and quality control in electronic components, glass ceramics, metal materials, biological samples, and other fields.
This device is based on the difference in X-ray penetration and material absorption, and uses a high-voltage generator to excite an X-ray tube (such as a tungsten target), generating a high-energy X-ray beam that penetrates the object being measured. Internal defects (such as pores, cracks, foreign objects) or structural differences can cause varying degrees of X-ray attenuation. Detectors (such as flat panel detectors or CCDs) convert the transmitted radiation into electrical signals, which are processed by software to generate grayscale images.
Desktop X-ray detectorAs a high-precision detection equipment, its core components can be summarized into the following five modules, which work together to achieve internal structural visualization detection:
1、 X-ray source system
X-ray tube
Core function: By heating the cathode, electrons are released, which are accelerated by the anode and collide with a target material (such as a tungsten target) to generate a high-energy X-ray beam.
Technical parameters: The tube voltage (40-90kV) and tube current (0.08-0.15mA) can be adjusted, which directly affects the radiation penetration and image contrast.
Design features: Some high-D devices use micro focus X-ray tubes, with a focus size that can be reduced to the micrometer level to improve image resolution.
high voltage generator
Provide a stable high-voltage power supply for X-ray tubes to ensure stable energy output and avoid image flickering or artifacts.
2、 Sample detection and motion control module
Sample stand
Function: Carrying the sample to be tested, supporting multi degree of freedom movement (such as X/Y/Z axis translation, rotation, tilt), achieving precise positioning and multi angle detection of the sample.
Design: Driven by high-precision stepper motors, the positioning accuracy can reach micrometer level, meeting the requirements of detecting small defects.
Mechanical architecture
Supporting structure: The casing is composed of a three-layer composite material of steel lead steel, and the lead layer effectively shields X-ray leakage to ensure operational safety.
Motion unit: Integrated stepper motor drive system controls the coordinated motion of the stage, X-ray tube, and detector to achieve low-speed stable scanning at high magnification.
3、 Image receiving and conversion device
Detector (probe)
Type:
Area array detector: including image intensifier (suitable for low resolution, large field of view detection) and flat panel detector (high-resolution, dynamic imaging).
Linear array detector: such as TDI (Time Delay Integral) detector, suitable for high-speed pipeline detection.
Function: Receive X-rays that have penetrated the sample, convert them into visible light or electrical signals, and form an initial image.
imaging system
Optical components: including lenses, filters, etc., optimize image clarity and contrast.
Real time display: Presenting detection images through a monitor, supporting real-time adjustment of parameters such as exposure time and gain.
4、 Image Processing and Analysis System
Software Control Platform
Function:
Parameter settings: Adjust X-ray energy, detection angle, scanning speed, etc.
Image processing: denoising, enhancement, edge detection, 3D reconstruction, etc., to improve defect recognition rate.
Data analysis: Automatically measure line segment curvature, cavity size, grayscale distribution, etc., and generate detection reports.
Features: Supports programming control and enables automated detection processes (such as batch testing and defect classification).
Storage and output
Store detection images and data, support exporting to common formats (such as JPEG, BMP, DICOM) for subsequent analysis or archiving.
5、 Security protection and auxiliary system
Radiation protection device
Lead door and safety shutter: automatically close during detection to prevent X-ray leakage.
Warning signs: Radiation warning signs are posted on the surface of the equipment to remind operators to pay attention to safety.
Interlock protection: The X-ray source cannot be started when the door is not closed, ensuring safe operation.
Environmental control module
Temperature and humidity monitoring: Ensure that the equipment operates in a suitable environment (such as temperature 20-25 ℃, humidity<60%) to avoid component aging.
Cooling system: Maintain equipment temperature stability and extend service life through fans or liquid cooling devices.
