PV Glass Laser Drilling Machine

Application
With the rise of photovoltaic double-glass modules, the demand for drilled back glass is increasing, and the drilling quality has become a key process link affecting the production of back glass. In response to the low-cost drilling requirements of thin glass, Han’s Photovoltaic Equipment has developed high-precision, high-efficiency precision laser drilling equipment.

Main Features

• Compatible with mainstream glass specifications (600*1200~1200*2500mm, thickness 1.6-5mm);
• The equipment includes acceleration section, rotation section, laser drilling section, rotation section and deceleration section;
• Compatible with long-side feeding (shingled type) and short-side feeding (conventional);
• The processing cycle is as fast as 6 pieces/min (diameter 12mm, thickness 2mm);
• Using highly stable laser, the process effect is stable.
