2.  Introduction:

The online vision inspection system utilizes cameras and image processing technology to automatically inspect product weld quality, component positioning, dimensional accuracy, surface defects, and more. By acquiring product images through high-speed cameras and advanced image processing algorithms, it achieves real-time online monitoring and inspection, replacing manual visual inspection and improving inspection efficiency and accuracy. It ensures product quality consistency and reliability, making it an indispensable quality control tool for lithium-ion battery module and pack production lines.

3. Working Process:

• The product to be inspected enters the vision inspection area.

• High-speed industrial cameras capture images of designated product areas.

• Images are transmitted to the image processing unit (industrial PC or embedded system).

• Computer vision algorithms process, analyze, detect defects, and measure dimensions from the images.

• The system determines if the product passes or fails based on preset standards.
  

• For failed products, an alarm signal is triggered to remove or stop the production line.

• Inspection results and data are recorded and stored for traceability and analysis.

4. Technical Specifications:

• Camera Resolution: 5-20 megapixels.
• Camera Frame Rate: 10-200 fps.
• Lens Focal Length: 8-50mm.
