Description

Technical Field

[0002] Display assembly equipment primarily includes automated alignment and lamination machines, bonding machines (COG / FOG), glue dispensers, curing ovens, and testers. Specialized industrial robots, vision positioning systems, and PLC controls enable precise assembly of components (such as panels, backlight modules, and driver ICs). The typical process involves: cleaning the substrate → automated alignment and lamination (such as with optical bonding adhesives) → driver chip bonding (using hot pressing or ultrasonic processes) → sealing and glue dispensing (using UV or thermal curing) → quality inspection (for brightness, color, and defects). The entire process requires a dust-free environment and automated control to ensure high yields.
