What is an X-Ray Intelligent Counter
2025-08-14
An X-ray counter (also known as an X-ray counting machine) uses X-ray technology to automatically count electronic components. Its core principle is based on the differential absorption of X-rays by materials and intelligent image recognition technology. Its main operating principles include the following:
1. X-ray Generation and Penetration
Ray Generation: A high-voltage generator provides a high voltage to the X-ray tube, causing electrons emitted by the cathode filament to collide with the anode target (such as tungsten metal) at high speed, generating X-rays.
Material Penetration: X-rays penetrate the tray or strip containing electronic components. Materials of varying densities (such as metal pins and plastic packaging) absorb the X-rays to varying degrees, resulting in varying intensities after penetration.
2. Image Capture and Signal Conversion
Detector Reception: A flat-panel detector (or parallel-plate detector) captures the X-rays after penetration and generates a grayscale image based on the intensity differences (high-density areas appear dark, low-density areas appear bright).
Signal Digitization: The detector converts the optical image into an electrical signal, which is then transmitted to the image processing system. III. Intelligent Image Processing and Counting
Image Preprocessing: Optimizes image quality through noise reduction, contrast enhancement, and other technologies.
Feature Recognition:
Contour Extraction: Utilizes edge detection algorithms to identify component shape, size, and position.
Layer Analysis: Utilizes deep image processing algorithms to identify hidden components layer by layer in multi-layered trays.
AI-Assisted Counting: Combining pattern recognition and deep learning algorithms, it matches component database features for accurate classification and automatic counting.
IV. Result Output
Processed data is displayed in real time on the user interface, generating quantity reports that can be synchronized to production management systems (such as MES). Data export and report printing are supported.

Working principle of dek 03ix printing machine
2025-07-03
Its core working principle includes three aspects: the visual positioning system captures MARK points on the PCB and steel mesh through up and down dual cameras, and achieves micrometer level alignment accuracy with high-speed lenses and independent light sources. The printing control system adopts a cantilever printing head design, and computer servo controls parameters such as pressure/speed/stroke of the scraper to ensure stable printing quality. The cleaning system has an automatic wiping function, including three modes of dry wiping/wet wiping/vacuum, and a programmable cleaning frequency of .
Other important information includes: the maximum processing size of the device is 510 × 508.5mm, with a repeatability accuracy of ± 25 μ m (6 σ standard), and it uses the Instinctiv V9 operating system. When answering, focus on highlighting these technical highlights and avoid excessive basic descriptions.
Considering that this is an industrial equipment description, we plan to use a structured presentation format, divided into two main parts: core systems and workflow. Insert thecomponent in the appropriate position to display the device structure diagram, and use thecomponent to supplement the technical parameter card. Although the search results for thecomponent mention videos with underlying principles, the specific link is not available, so we have decided not to insert the video component.
1、 Core system composition and functions
Visual positioning system
Dual view alignment: By independently controlling the up/down view optical lens, the MARK points on the PCB and steel mesh are captured at high speed to achieve precise alignment, with a repeat positioning accuracy of ± 25 microns (6 Sigma standard).
Light source adjustment: The independent lighting system can dynamically optimize lighting conditions to ensure image recognition stability. 13
Printing control system
Cantilever printing head: Designed with a high rigidity structure, the scraper pressure, speed, and stroke are all controlled by computer servo to ensure printing uniformity.
Scraper parameters: The metal scraper operates at an angle of 45 ° -60 °, with a pressure range of 3-15N/cm ² and a speed of 20-80mm/s, ensuring that the solder paste fully fills the steel mesh openings. 34
PCB processing device
Dynamic clamping system: The magnetic top pin and edge clamping device are adaptive to PCBs of different sizes/thicknesses (up to 510mm × 508.5mm), effectively overcoming circuit board deformation.
Supporting pins: prevent PCB bending during the printing process and maintain flatness. 34
Steel mesh cleaning system
Automated cleaning: Programmable selection of dry wipe, wet wipe, or vacuum adsorption modes to remove residual solder paste at the bottom of the steel mesh according to the set cycle, avoiding hole blockage
Detailed explanation of workflow
1. PCB positioning
The PCB enters the equipment through a conveyor belt, and the fixture automatically clamps and locates it. The visual system scans the MARK points and calibrates the position of the steel mesh and PCB.
2. Solder paste filling
The scraper moves horizontally to evenly press the solder paste into the steel mesh opening. The servo system adjusts the parameters of the scraper in real time to ensure that the opening filling rate is greater than 95%.
3. Demoulding and transfer printing
The steel mesh is separated from the PCB, and solder paste is precisely deposited on the solder pads. The demolding speed and spacing should match the viscosity of the solder paste to prevent pulling or bridging.
4. Cleaning and Quality Inspection
After completing multiple prints, the automatic wiping device cleans the bottom surface of the steel mesh; Some models integrate SPI (solder paste detector) linkage function to monitor printing quality in real-time
Key technological advantages
Precision control: Driven by high-precision servo motors, combined with the Instinctiv V9 operating interface, achieving a printing accuracy of ± 25 μ m.
Stability design: The lightweight structure of the cantilever scraper crossbeam reduces inertia, and the printing repeatability Cpk is greater than 2.0.
Intelligent diagnosis: The fault self checking system prompts abnormal causes (such as scraper pressure deviation, visual alignment failure, etc.) through sound and light alarms.
