Working Principle of?Thin-film Solar Laser Scribing Mass Production Machine

1. Laser Scribing

   • Ultrafast lasers perform precise scribing on thin-film solar cell layers, creating P1-P3 lines for electrical isolation.

   • Multiple wavelengths are available (355nm, 532nm, 1064nm) to match material absorption characteristics.

2. Mechanical Beam Splitting

   • The laser beam is split into multiple processing channels, each equipped with an attenuation module to maintain power fluctuation ≤3%.

3. Motion and Positioning System

   • The product remains stationary while a multi-channel scribing head moves, preventing vibration-related defects.

   • X/Y axes driven by linear motors, achieving positioning accuracy ≤±3μm and repeatability ≤±2μm.

   • High- and low-magnification industrial cameras (CCD) combined with telecentric lenses enable visual positioning and distance measurement.

4. Flying Optical Path Scribing

   • The Y-axis utilizes flying optical path scanning for high-speed scribing, with maximum speeds ≥1.5 m/s.

5. Automation and Data Control

   • Fully automated operation with automatic loading/unloading; semi-automatic mode for parameter testing.

   • Professional software allows process editing and supports standard file formats such as Gerber, DXF, and DWG.

Operational Guidelines

1. Ensure substrates are securely fixed to avoid scribing errors.

2. Regularly inspect laser optical paths and attenuation modules to maintain power fluctuation ≤3%.

3. Use compressed air (0.5–0.7 MPa) to clear debris from the scribing area.

4. Install equipment on a vibration-isolated foundation to ensure precision.

5. Adjust laser power and process parameters according to material type to prevent over-ablation.

6. Maintain CCD cameras and vision systems regularly for precise positioning.
