Abstract
UV curing of adhesives with light beam shaping utilizes a spot curing process that focuses a limited amount of UV light onto a target area, such as glue dots. A focusing lens may be used to direct the UV light beam to the target area. The target areas have different geometrical shapes, and the UV light is advantageously concentrated in a more efficient manner. Beam-shaping optics or lenses are used to facilitate re-shaping and re-defining the UV-light beam. The UV beam may be defined and limited to a rectangular spot to improve the spot process quality and efficiency.
