Patent ID: 11454293

Abstract:
A diaphragm transfer device sucks and transfers a diaphragm that includes a first protrusion protruding in a direction perpendicular to the surface of the diaphragm. The diaphragm transfer device is provided with: a placing table on which the diaphragm is placed in such an orientation that the first protrusion faces downward; and a suction pad that sucks the diaphragm, placed on the placing table, from above on the outer circumferential side of the protrusion. The placing table includes an annular pedestal facing an outer-circumferential-side thick portion of the diaphragm, the thick portion being sucked by the suction pad, and a second recess recessed downward on the inner diameter side of the pedestal. The whole first protrusion of the diaphragm is located inside the second recess in a top view.
