A tool for positioning spacers (7) on a first plate (1) intended for being maintained at a distance from a second plate (4) by said spacers, said tool including openings for receiving said spacers, wherein said openings (32-35-32) 32′-35-32, 32′-35′-32′, 61, 67-64-68, 72-74, 76, 83-82, 88-89-88, 99) are of variable size between a first position of introduction of the spacers and a second position of mechanical blocking of the spacers.
A method of positioning spacers in a tool including openings for receiving said spacers, wherein said openings (32-35-32, 32′-35-32, 32′-35′-32′, 61, 67-64-68, 72-74, 76, 83-82, 88-89-88, 99) are of variable size between a first position of introduction of the spacers and a second position of mechanical blocking of the spacers, said method comprising:
- placing a spacer (7) in each opening (32-35-32, 32′-35-32, 32′-35′-32′, 61, 67-64-68, 72-74, 76, 83-82, 88-89-88, 99) of the positioning tool in a first position using a vacuum table (20);
- and performing successive suction and blowing cycles, by applying a free end of the spacers against an alignment plate (52), before their locking in their position by narrowing of the openings.
