The liquid level sensor smart production line is compatible with flexible production for multiple versions of materials, equipped with a high-precision servo multi-station divider to achieve synchronized precise control throughout the entire process. It integrates a CCD vision inspection system, which can automatically identify anomalies such as stains, scratches, welding point defects, cracks, and misalignment of components and intelligently sort them. The system simultaneously completes core processes such as riveting, robotic flexible assembly, automatic soldering, and precise spring installation. The production line's cycle time is compressed to within 15 seconds. Through the collaboration of automated modules and robotic flexible operations, the production line combines high production rhythm and high yield, meeting the needs for complex process integration and stable mass production.
