1. Pouched-type secondary battery packaging equipment comprising:
a pallet on which a cell assembly, in which a cell is accommodated inside a pouch, is placed;
a loading robot configured to lift the cell assembly to be seated on the pallet;
a pallet rail along which the pallet is guided;
a marking printer configured to generate a mark on the cell assembly placed on the pallet;
a mark reader configured to read the mark generated by the marking printer;
a first meter configured to measure a weight of the cell assembly;
an injector provided with an injection nozzle configured to inject an electrolyte into the pouch of the cell assembly;
a second meter configured to measure a weight of the cell assembly having the electrolyte injected thereinto;
a sealer provided with a vacuum chamber, into which the cell assembly is put, and configured to seal the pouch;
an inspector configured to inspect the cell assembly sealed by the sealer; and
an unloading robot configured to lift and unload the cell assembly,
wherein the pallet rail comprises:
a first rail and a second rail, the first rail and the second rail being parallel to each other;
a third rail connecting a second end of the first rail to a second end of the second rail; and
a fourth rail connecting a first end of the first rail to a first end of the second rail, wherein the marking printer, the mark reader, the first meter, the injector, the second meter, the sealer, and the inspector are sequentially disposed in a line along the first rail from the first end to the second end,
wherein the unloading robot is configured to unload the cell assembly from the pallet located after the inspector,
wherein the unloading robot is disposed closer to the second end of the first rail than the first end of the first rail,
wherein the loading robot is configured to lift the cell assembly to the pallet disposed before the marking printer, and
wherein the loading robot is disposed closer to the first end of the first rail than the second end of the first rail.
