1. An automatic metal sorting system using laser induced breakdown spectroscopy, the automatic metal sorting system comprising:
a conveyer configured to move waste metals at a constant speed;
a shape measurer configured to measure a position and a shape of at least one waste metal on the conveyer;
a laser induced breakdown spectroscopic device configured to determine the kind of the waste metal by emitting a laser to the waste metal and receiving and analyzing a plasma spectrum signal generated by the emitted laser; and
a discharger configured to separate and discharge the waste metal in accordance with the determined kind of the waste metal,
wherein the laser induced breakdown spectroscopic device includes:
a laser emitter configured to emit the laser;
a focusing module configured to receive the laser from the laser emitter, and adjust a focal length of the laser in accordance with a change in positions and shapes of the waste metals;
a dichroic mirror configured to receive the laser having the adjusted focal length from the focusing module, and transmit the received laser; and
a galvano-scanner configured to receive the laser from the dichroic mirror, and direct the laser to the waste metals located on the conveyer by changing a direction of the laser emitted from the laser emitter by adjusting an angle of a mirror disposed in the galvano-scanner, and
wherein the focusing module is positioned between the dichroic mirror and the laser emitter, and the dichroic mirror is positioned between the focusing module and the galvano-scanner.
