Coating sprayer, method for assembling and disassembling

A sprayer to be mounted on a robot, the sprayer comprising:

• an air guide, the air guide being an air skirt,
• a fixed member of the sprayer, the fixed member being a turbine stator,
• at least one magnet mounted on a first component from among the air guide and the fixed member, and
• at least one ferromagnetic part made from a ferromagnetic material, which is intended to cooperate with the at least one magnet and which is mounted on or defined by the other component from among the air guide and the fixed member, wherein
• the air guide is fastened to the fixed member by the at least one magnet and the at least one ferromagnetic part,
• the at least one magnet and the at least one ferromagnetic part generate a magnetic attraction force between the at least one magnet and the at least one ferromagnetic part between 10 kN and 200 kN,
• the fixed member is traversed by independent circuits and complementary independent circuits, complementary to the independent circuits traversing the fixed member, that are arranged through the air guide, the independent circuits including at least one compressed air circuit between the turbine stator and the air skirt, and
• the air guide and the fixed member are provided with matching elements arranged to position the fixed member with respect to the air guide in a predefined angular position, the predefined angular position being configured to connect the independent circuits of the fixed member and the complementary independent circuits of the air guide.
