Manufacturing device for a light guide plate

摘要

A manufacturing device includes a feeder, a first pressing roller, a second pressing roller, a third pressing roller, a transmission assembly, and a driving assembly. The first pressing roller and the second pressing roller cooperatively press a hot melt adhesive from the feeder to obtain a preprocessed light guide plate. A temperature of the second pressing roller is lower than a temperature of the hot melt adhesive. The third pressing roller separates the preprocessed light guide plate from the second pressing roller to obtain a light guide plate. The transmission assembly connects the second pressing roller and the third pressing roller. The driving element is connected to the transmission assembly, and drives the transmission assembly to rotate the third pressing roller around the second pressing roller, and thus adjusting a contact area and a contact time between the light guide plate and the second pressing roller.
