研究目的
To propose a novel laser composite separation method for laminated glass by combining laser-induced thermal-crack propagation and laser thermal melting to simplify the cutting process and improve separation quality.
研究成果
The laser composite separation method successfully simplified the laminated glass cutting process from five steps to two, achieving high-quality separation without defects. The method has potential for industrial application and further research into materials with more layers.
研究不足
The method is currently optimized for laminated glass with a specific thickness and may require adjustments for materials with more layers or different properties.
1：Experimental Design and Method Selection:
Utilized a multi-focus separating head to generate three laser foci for simultaneous action on each layer of laminated glass.
2：Sample Selection and Data Sources:
Commercial laminated glass with specific dimensions and properties was used.
3：List of Experimental Equipment and Materials:
Included a CW fiber laser, multi-focus separating head, and 2D moving platform.
4：Experimental Procedures and Operational Workflow:
Laser foci were adjusted to act on each layer, and the laminated glass was moved relative to the laser beam for separation.
5：Data Analysis Methods:
Optical microscopy, SEM, and 3D surface profilometer were used to analyze separation quality.
