AI Technical Summary
Existing technologies have problems with uneven film thickness distribution and uneven spraying on 3D curved glass. In particular, the uneven film thickness distribution is caused by the real-time changes in the distance and angle between the curved surface R-corner and the arc area and the spray gun. Traditional fixed spray guns cannot follow the changes in the curved surface contour, resulting in defects such as local missed spraying, pitting, and sagging.
A 3D curved glass AG conformal spraying process based on a six-axis robot is adopted. Through 3D contour acquisition, robot trajectory generation, spray gun posture adaptation and real-time compensation of spraying parameters, the spray gun is made perpendicular to the glass surface. The spraying air pressure, liquid flow rate and robot movement speed are adjusted in real time, and closed-loop control is achieved by combining online haze/film thickness detection.
It achieves full-area haze deviation control within ±1.0% and film thickness deviation ≤ ±0.1μm for 3D curved glass. The spray gun is always perpendicular to the glass surface, avoiding R-corner accumulation, arc surface missed spraying and dripping, improving the yield rate by 20% to 35%, and adapting to 3D curved glass with arbitrary curvature.
