LIGENT Industrial Robotics unveiled a comprehensive solution for automated sand core loading production lines. Featuring customized equipment configurations, intelligent control systems, and efficient production cycle designs, this solution offers a new pathway for the automation and intelligent transformation of sand core processing in the manufacturing industry, helping manufacturers achieve efficiency gains and process upgrades.

This newly launched sand core feeding production line is a turnkey solution developed by LIGENT specifically for the characteristics of sand core processing. It encompasses the R&D and manufacturing of robot bodies, customized grippers, automated conveyors, and supporting auxiliary equipment, while also providing end-to-end services ranging from installation and commissioning to personnel training and after-sales maintenance. Centered around two LIGENT industrial robots, the production line integrates modular units such as vision tracking, grinding and deburring, and precision positioning to establish a fully integrated automated production process. It achieves full automation across all stages—from loading, gripping, and positioning to grinding and feeding into the sand core machine—with a theoretical production cycle of just 48 seconds, significantly enhancing production efficiency and process stability in sand core processing.

In terms of equipment R&D and configuration, LIGENT has thoroughly considered the process requirements of sand core machining to develop multiple customized core components. The integrated vision-gripping and grinding-feeding robotic grippers are constructed from lightweight materials and equipped with a vacuum-based workpiece detection function, ensuring precise, error-free workpiece gripping; The grinding gripper integrates an adjustable grinding head and air-blowing nozzle assembly, simultaneously removing burrs and clearing debris to maintain a clean processing environment and equipment without affecting the production cycle. The positioning table is equipped with multiple air-blowing devices and adjustable contouring positioning pins, ensuring a clean loading surface and precise positioning, thereby laying a solid foundation for production stability at the hardware level.

The innovative design of the control system is one of the core highlights of this production line. LIGENT employs a decentralized control model, with the loading table controlled by an independent PLC. Robots communicate only with upstream and downstream associated equipment, while peripheral devices for each robot are autonomously controlled by the robot itself. This not only facilitates rapid switching between workpiece types and flexible addition or removal of production processes but also significantly reduces the difficulty of troubleshooting and maintenance. Daily operations and maintenance can be performed without specialized or complex control knowledge, adapting to diverse enterprise production needs.

The various LIGENT industrial robot models deployed in this solution all feature 6-axis high-degree-of-freedom capabilities and ±0.06mm high repeatability. Different robot models can be adapted to varying payloads and working radii based on production requirements. Their joint operating speeds and working ranges balance efficiency and flexibility, while their protection ratings and operating temperature ranges are suited to complex industrial production environments, providing the core driving force for the production line’s stable operation. Additionally, all mechanical and electrical components on the production line are selected from high-quality configurations, ensuring equipment durability and operational stability from the outset.

Furthermore, the LIGENT sand core feeding production line features a standardized design for the production environment, clearly defining requirements for environmental parameters such as power supply, air pressure, temperature and humidity, and floor load capacity. This design is compatible with mainstream industrial production sites, facilitating rapid deployment by enterprises.

The launch of this sand core feeding production line solution represents another innovative achievement by LIGENT in the foundry processing sector. It not only demonstrates LIGENT’s core capabilities in industrial robot R&D, system integration, and process adaptation but will also inject new momentum into the transformation of traditional manufacturing toward intelligent and efficient operations. Moving forward, LIGENT will continue to deepen its commitment to industrial automation technology R&D, consistently introducing solutions that align with industry needs. This will help more manufacturing enterprises achieve production upgrades and drive the high-quality development of the smart manufacturing industry.
