Summary

This case study introduces how Dadisick safety light curtains were applied in a lithium battery cell automated production line to protect operators at robotic and high-speed workstations, enhancing safety while maintaining production efficiency.

Customer Background

With the rapid growth of the lithium battery industry, manufacturers are increasingly relying on highly automated production lines to meet rising demands for efficiency, consistency, and output. In lithium battery cell manufacturing, processes such as assembly, inspection, and material handling are often performed at high speed and with minimal tolerance for error.

In this project, the customer operates a fully automated lithium battery cell production line integrating multiple processing stations and an industrial robot for material transfer. While automation significantly improved productivity, it also introduced potential safety risks during manual intervention, maintenance, and troubleshooting stages. Ensuring operator safety without compromising production efficiency became a critical requirement.

Safety Challenges

Safety Light Curtain Protection for Lithium Battery Cell Automated Production Line

The production line features multiple linear workstations and robotic handling units operating in proximity. Key safety challenges included:

· Frequent access points for operators during setup, adjustment, and maintenance

· High-speed moving components and robotic arms create potential pinch and impact hazards

· Limited space, making traditional mechanical guarding impractical

· The need to maintain production continuity without excessive downtime

The customer required a safety solution that could provide reliable personnel protection while allowing rapid access and minimal impact on cycle time.

Dadisick Safety Light Curtain Solution

To address these challenges, Dadisick safety light curtains were installed at critical access points along the lithium battery cell production line. The safety light curtains create an invisible infrared protective field around hazardous areas. When an operator enters the protected zone, the system immediately sends a stop signal to the machine or robot controller, preventing potential injury.

Key advantages of the Dadisick solution include:

· Fast response time, suitable for high-speed automated equipment

· Stable detection performance in complex industrial environments

· Flexible protective height and resolution options, adapting to different access openings

· Compact design, ideal for space-constrained lithium battery production lines

· Easy integration with existing PLC and safety control systems

By selecting appropriate beam spacing and protective height, the safety light curtains ensured compliance with industrial safety standards while maintaining smooth production flow.

Implementation Results

After installation, the safety system successfully enhanced operator protection across the entire lithium battery cell production line. Operators can now safely access the equipment for inspection or maintenance without relying on manual lockout procedures, significantly reducing downtime.

The customer achieved:

· Improved workplace safety and reduced accident risk

· Higher production efficiency with minimal interruption

· Simplified safety management and system integration

· Increased confidence in meeting internal and regulatory safety requirements
