Fully Automatic X-Ray Inspection Machine for Battery Cells
The Fully Automatic X-Ray Inspection Machine for Battery Cells is a device specialized in detecting internal defects of lithium-ion battery cells. Below is a detailed introduction:
Working Principle
The machine generates X-rays via an X-ray tube, which penetrate the interior of battery cells. Different materials inside the cell (such as electrodes and separators) absorb and attenuate X-rays to varying degrees due to differences in density and atomic number. The attenuated X-rays reach a detector, which converts the X-ray signals into electrical or digital signals. After digital processing, analyzable images are generated. These images are processed and analyzed by dedicated software to identify internal defects in the battery cells.
Main Functions
Defect Detection: Identifies multiple internal defects in battery cells, including poor alignment of pole pieces, short circuits, open circuits, bubbles, impurities, and deformation.
Dimensional Measurement: Automatically measures dimensional parameters such as the alignment of battery positive and negative pole pieces, and calculates statistical data including maximum, minimum, and average values.
Good/Bad Sorting: Automatically distinguishes between good and defective products based on preset standards, and sorts defective products automatically.
Technical Features
High Precision: Detection accuracy typically reaches the micron level. For example, Zhuomao Technology’s XB7100 achieves a detection accuracy of 5-15μm with a repeatability of 30μm, while Zhengye Technology’s XG5500 offers a repeat testing accuracy of 60μm.
High Efficiency: Fast detection speed meets the high-speed production needs of production lines. For instance, Zhuomao Technology’s XB7100 reaches a maximum detection efficiency of 60 PPM, and its XB8100 achieves ≥90 PPM.
High Automation: Enables fully intelligent automatic loading/unloading, online inspection, automatic sorting of OK/NG products, and supports automatic reflow and retesting of NG products.
Strong Data Management: Integrates with MES systems via an interaction module to upload visual data in real time. Equipped with an automatic barcode scanning function, it ensures traceability of production data.
Safety and Environmental Protection: Typically features safety interlocks and multiple protection functions, complying with national safety radiation standards. For example, Zhengye Technology’s XG5500 meets safety radiation standards on all surface parts, with radiation leakage ≤1μSV/hr.
Application Fields
The Fully Automatic X-Ray Inspection Machine for Battery Cells is mainly used in the production of lithium-ion batteries, including electric vehicle batteries, consumer electronics batteries, and energy storage batteries. It ensures the quality and safety of lithium-ion batteries, improving production efficiency and yield rates.
