SCRIBING DEVICE USING LASER USABLE IN LARGE LIGHT GUIDE PLATE AND PROCESSING PLATE

摘要

PURPOSE: A scribing device using a laser is provided to improve an exterior, brightness, and uniformity of a light guide plate by uniformly controlling a focus of a laser beam even in a large light guide plate. CONSTITUTION: A table(160) is installed to arrange an object(162) of laser processing thereon. A laser oscillator(110) emits a laser beam to the object of laser processing on the table. A head(140) is installed on the table, and applies the laser beam transmitted from the laser oscillator to the object of laser processing. An optical fiber(130) is connected between the laser oscillator and the head for transmitting the laser beam emitted from the laser oscillator to the head. A condenser lens is arranged between the laser oscillator and the optical fiber for condensing the laser beam emitted from the laser oscillator into the optical fiber. The table and the heads relatively move in X-Y direction.
