The invention discloses a novel turntable-type liquid injection machine of a soft package lithium battery. The liquid injection machine comprises a transmission device, a weighing device before liquid injection, a turntable-type liquid injection device, a weighing device after liquid injection and a quadruple rotary manipulator, wherein the quadruple rotary manipulator is arranged among the transmission device, the weighting device before liquid injection, the turntable-type liquid injection device and the weighting device after liquid injection and rotates among the transmission device, the weighting device before liquid injection, the turntable-type liquid injection device and the weighting device after liquid injection so that the soft package lithium battery moves among the transmission device, the weighting device before liquid injection, the turntable-type liquid injection device and the weighting device after liquid injection. The novel turntable-type liquid injection machine of the soft package lithium battery, disclosed by the invention, has the advantages of compact structure and short production line, and the occupied volume is reduced.
