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 detectorThe operation steps are as follows:
1. Environmental preparation and safety protection
Place the device in a dry and stable environment, away from strong electromagnetic interference sources, and ensure good ventilation.
It is recommended to control the laboratory temperature at 20-25 ℃ and the relative humidity below 60%.
Operators need to receive radiation safety training, wear lead protective clothing, lead goggles, protective gloves and other equipment, and set up warning signs around the equipment.
2. Equipment inspection and preheating
Before starting up, check whether the appearance of the device is intact, whether the connections of each component are tight, and confirm that the power cord is not damaged.
After turning on the power, the device needs to be preheated for 15-30 minutes (refer to the instruction manual for specific time), and then proceed with subsequent operations after the system stabilizes.
During the preheating period, do not operate buttons or open doors to avoid damaging the equipment.
3. Sample preparation and placement
Choose the appropriate processing method based on the sample type (solid, powder, liquid):
Solid samples: Ensure a smooth and even surface, and if necessary, wipe with a dust-free cloth to remove dust or grease.
Powder samples: pressed into sheets or loaded into specialized sample cups to prevent scattering.
Liquid samples: Fill into leak proof containers to avoid spillage.
Place the sample on the testing platform, adjust the position to align the test area with the center of the testing window, and ensure that the sample is stable and free from shaking.
4. Parameter setting and calibration
Set detection parameters through the control panel or software, including X-ray energy (usually 40-90kV), current (0.08-0.15mA), detection angle, scanning speed, etc.
Select standard samples for calibration based on analysis elements, and strictly follow the instructions to ensure data accuracy during the calibration process.
Some devices support automatic calibration function, which can simplify the operation process.
5. Initiate detection and image acquisition
Close the inspection hatch and confirm that the safety interlock device is activated (such as the lead door closing indicator light on).
Start the X-ray source, control the detection probe to move to the target position through software, and begin scanning.
Real time observation of images or data on the display screen, adjusting the sample position or detection parameters as needed (such as rotating the sample stage, adjusting the C-arm angle).
6. Data analysis and result interpretation
After the detection is completed, the software automatically generates an analysis report, displaying information such as element content percentage and defect location.
Experienced operators or professionals review data, identify potential defects (such as cracks, pores) or outliers, and evaluate their importance.
Multiple measurement tools, such as bubble detection and CNC automatic detection, can be used to assist in the analysis of complex images.
7. Equipment shutdown and maintenance
After the detection is completed, turn off the X-ray source first and wait for the system to cool down (about 10-20 minutes) before turning off the power.
Clean the sample residue, wipe the testing table and cabin ring with a soft cloth, and keep the interior of the equipment clean.
Regularly inspect the condition of equipment components (such as radiation tubes, cables, silicone grease), replace consumables or perform maintenance according to the instructions.
Record the testing parameters, sample information, and results, and archive them for future reference.
