The present invention relates to a laser cutting device comprising: a laser unit cutting a cutting subject by emitting a laser beam to the cutting subject along a preset cutting route; a stage unit continuously transferring the cutting subject along a preset transferring route; an encoder unit outputting encoder pulses every time when the cutting subject is transferred to as much as a preset distance along the transferring route; a trigger unit outputting trigger pulses corresponding to the encoder pulses; and a cutting route storing unit storing a plurality of unit cutting sections generated by dividing the cutting route based on the transferring distance of the cutting subject per unit trigger pulse. The laser unit emits the laser beam along the unit cutting section in correspondence with a current position of the cutting subject among the plurality of unit cutting sections every time when the trigger pulse is emitted. According to the present invention, the laser cutting device is capable of laser-cutting the cutting subject while continuously transferring the cutting subject, thereby reducing a time required for laser cutting. In addition, the laser cutting device is capable of laser-cutting the cutting subject while transferring the cutting subject at a constant speed, thereby constantly maintaining a quality of a cut surface of the cutting subject. |
