AI Technical Summary
During laser cutting, local areas of the LCD color film are irradiated by a high-energy laser beam, causing a rapid increase in temperature. This leads to melting, carbonization, or decomposition of the material edges, resulting in burnt edges that affect product quality.
Cooling mechanisms are installed on both sides of the cutting assembly. Cooling gas is sprayed out through nozzles. The airflow is controlled by a pressure relief valve and a gas supply pipe. The nozzle angle and position are adjusted by an adjustment mechanism to achieve pre-cooling and secondary cooling after cutting, preventing the edges of the color film from melting, carbonizing or decomposing.
It significantly improves cutting quality and product yield, prevents damage to the edges of the color film, and ensures cutting accuracy and efficiency.
