Claim 4:
5. The automated gas supply system of claim 1, wherein the gas cabinet includes:
a clamp module disposed on a sidewall of the gas cabinet and configured to clamp a side surface of the gas cylinder;
a second seating unit on which the gas cylinder is seated, the second seating unit being among the one or more seating units;
a fastening unit which is disposed on the sidewall of the gas cabinet at a side surface of the gas spray nozzle of the gas cylinder and includes a Compressed Gas Association (CGA) holder unit connected to the gas pipe and an end cap holder unit coupled to an end cap, which is coupled to the gas spray nozzle of the gas cylinder, to separate the end cap from the gas spray nozzle or couple the end cap to the gas spray nozzle;
a CGA plug unit which is disposed on the sidewall of the gas cabinet at the side surface of the gas spray nozzle of the gas cylinder and configured to be fastened to the CGA holder unit in a case where the gas cylinder is not present on the second seating unit;
a first guide rail which is disposed on an upper surface of the gas cabinet and extends in a second direction which is a longitudinal direction of the gas cabinet;
a second guide rail which is disposed on a lower surface of the first guide rail and extends in a first direction perpendicular to the second direction;
a third guide rail which is coupled to the second guide rail and extends in a third direction perpendicular to the first direction and the second direction;
a traveling unit which is coupled to the third guide rail and includes a first actuator so as to move in the first to third directions along the first to third guide rails; and
a common fastening device which is coupled to the traveling unit to move in the first to third directions and includes a second actuator coupled to the fastening unit to rotate at least one of the CGA holder unit and the end cap holder unit.
