Roll-to-Roll Laser Scribing & Edge-Cleaning System​

Roll-to-Roll Laser Edge Cleaning Equipment

Application Field:
Laser edge cleaning for thin-film solar cells.

Structural Features:

• Three-station design incorporating an unwinding mechanism, laser processing host, and rewinding mechanism

• Edge-cleaning modules mounted on a fixed gantry structure, with irradiation from the upper coated surface

• Optical system capable of simultaneous edge cleaning using multiple lasers and optical modules

• Highly integrated automation control system, optical processing system, and imaging system for stable and reliable operation

  
  

Product Advantages:

• Multiple independently controlled edge-cleaning axes and optical modules with flexible parameter settings – no mutual interference during simultaneous operation for high efficiency

• Independent following-type dust collection port with excellent dust removal performance

• Triple-vision edge detection and positioning system ensures higher edge-cleaning positional accuracy

  
  

Typical Applications:
In thin-film solar cell production, this equipment is used to remove excess materials or coatings from cell edges, significantly improving cell performance and quality. For instance:

1. Mass Production Lines: Enables rapid, high-efficiency edge cleaning in large-scale manufacturing facilities by leveraging its multi-axis/multi-module simultaneous operation capability

2. Precision Processing: The triple-vision positioning system ensures micron-level accuracy for critical edge treatment processes

3. Flexible Manufacturing: Adaptable to various thin-film solar cell designs (e.g., CIGS, CdTe) with customizable parameter settings for different coating materials

4. Clean Production: Integrated dust collection system maintains clean processing environments while meeting industrial emission standards

The equipment particularly excels in:

• High-throughput production environments requiring >95% edge-cleaning consistency

• Next-generation solar cells demanding <50μm edge treatment precision

• Automated lines where seamless integration with upstream/downstream processes is crucial
