1. A device for inserting sealing pads into one of a plurality of sectors that form a turbine stator of a turbine, the one sector comprising a side face and a plurality of slots arranged in the side face and each slot configured to receive a predefined sealing pad, the device comprising:
a support configured to support the one sector;
a first robot arm comprising a first means for gripping the sealing pads, each sealing pad being predefined in accordance with a corresponding one of the plurality of slots that receives the sealing pad, the first robot arm being configured to insert each predefined sealing pad into each of the corresponding slots of the side face of the one sector; and
a system for preparing sealing pads comprising a receptacle adapted to receive a plurality of sealing pads and a second robot arm comprising a second means for gripping sealing pads in the receptacle, the second means for gripping being adapted to deposit the sealing pads on a sealing pads support and wherein the first means for gripping is adapted for gripping sealing pads supported by the sealing pads support and orientable for the insertion of sealing pads into the slots of the side face of the one sector,
wherein:
the receptacle comprises a plurality of bins, each containing loose sealing pads of a same type different from one bin to another;
the sealing pads support comprises a plurality of zones, each zone being associated with a type of pad; and
the second robot arm is configured to identify at least one sealing pad that is grippable by the second means for gripping in each bin, grip one sealing pad from each bin and deposit each in the zone of the sealing pads support associated with the type of the gripped pad.
