Apparatus for processing light guide plate by laser

An apparatus for processing a light guide plate using laser is provided to adjust distance between a focus lens and the light guide plate by transferring a laser generator and a laser head to left and right sides for changing processed depth of the light guide plate, thereby enabling the light guide plate to be processed with desired depth. An apparatus for processing a light guide plate(P) using laser comprises a laser generator(10), a laser head(20), and a distance adjusting unit(30). The laser generator oscillates a laser beam to the outside. The laser head has a focus lens for receiving the laser beam oscillated from the laser generator. The distance adjusting unit changes the distance from the focus lens to the light guide plate. The laser head has an upper and lower body tubes. The distance adjusting unit includes upper and lower brackets, a servo motor, and a distance adjusting part. A left and right transfer unit(40) moves the laser generator and the laser head to left and right sides. The left and right transfer unit is guided by a guide rail(50). Thereby, the light guide plate is processed with desired depth.
