Industry Background
In LCD manufacturing, cleaning processes are essential across cutting, grinding, developing, etching, and inspection stages. As LCD panels become larger, thinner, and more precise, cleaning systems must efficiently remove particles, chemical residues, and moisture without damaging delicate surfaces, ensuring stable downstream processing and high yield.
Common Cleaning Problems in LCD Line
Problem 1: Surface particle residue
Incomplete cleaning leaves dust or debris on glass surfaces, affecting display uniformity and bonding quality.
Problem 2: Water marks and chemical residue
Residual moisture or chemicals after cleaning lead to surface defects.
Problem 3: Uneven cleaning due to brush wear
Aging or mismatched brush rollers cause uneven pressure and increase scratch risk.
Problem 4: Frequent maintenance
High humidity and chemical exposure shorten component lifespan and increase downtime.
Engineering Causes
-
Uneven water flow and mechanical contact at high line speeds
-
Insufficient chemical resistance of cleaning materials
-
Inefficient water absorption and drainage
-
Long-term fatigue in wet processing environments
