Application Scenario

During the production of bare cells, processes like winding, stacking, and Mylar film wrapping can lead to defects such as wrinkles, scratches, and folded tabs. To ensure that battery quality meets production standards, visual inspection at this stage must achieve zero defects to prevent faulty products from entering the packaging phase.

Project Challenges

    1. Variety of Defects: Bare cell appearance defects can range from obvious issues like surface scratches, damage, and wrinkles to subtle flaws such as tiny bubbles and protrusions that are difficult to detect. The wide variety of defects requires multiple lighting schemes, and multiple inspection stations are necessary to capture images and avoid missed detections.

    2. Environmental Interference: During surface defect detection, factors like complex environments and material properties can interfere with visual inspection, making it challenging to distinguish between dust, impurities, and scratches.

I-TEK Solution: 4K Color Line Scan Camera

    1. Advanced CMOS Sensor: The I-TEK 4K color line scan camera integrates an advanced global shutter CMOS sensor with excellent color reproduction, ensuring high-accuracy detection of appearance defects. It is ideal for applications with high image capture requirements.

    2. High Responsiveness and Efficiency: The camera's fast response speed and efficient image extraction software allow multiple independent images to be captured with different lighting at a single inspection station. This reduces the number of inspection stations needed and lowers the overall cost of the visual system.

    3. Proven Performance: This camera is a classic product from I-TEK, with extensive market application experience. It combines powerful performance with high cost-effectiveness, making it a reliable and stable choice.
