Fully Automatic X-Ray Inspection Machine for Cylindrical Batteries

The Fully Automatic X-Ray Inspection Machine for Cylindrical Batteries is a specialized device for non-destructive testing of internal quality in cylindrical lithium-ion batteries (e.g., models 18650, 21700, 4680). It leverages X-ray imaging to visualize hidden structures and defects, ensuring battery safety, performance, and compliance with production standards.

Working Principle

X-Ray Emission & Penetration: An X-ray generator emits X-rays that penetrate the cylindrical battery. Different internal components (electrodes, tabs, separators, electrolytes) absorb X-rays differently due to varying density and atomic number.

Imaging & Signal Conversion: A high-resolution detector (e.g., TDI line-scan detector, flat-panel detector) captures the attenuated X-rays and converts them into digital signals.

Automatic Analysis: Dedicated software processes the digital images, identifies defects (via preset criteria), and compares measured parameters (e.g., tab alignment) with standards to judge “good (OK)” or “defective (NG)” products.
