A multifunction cap replacement module includes a cap rotation module supporter and at least one cap rotation module. The cap rotation module is mounted to the cap rotation module supporter, and the cap rotation module includes a first cap rotation device and a second cap rotation device. The first cap rotation device is configured to open one sealing cap of at least one chemical drum and extract a chemical liquid from the chemical drum, and the second cap rotation device is configured to open another one sealing cap of the chemical drum and allow the chemical liquid to flow back to the chemical drum.
