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.

First claim

What is claimed is:

1. A diaphragm transfer device for sucking and transferring a diaphragm that includes a protrusion protruding in a direction perpendicular to a surface of the diaphragm, the diaphragm transfer device comprising:
a placing table on which a diaphragm is placed in such an orientation that the protrusion faces downward; and
a suction pad that sucks the diaphragm placed on the placing table, from above on an outer circumferential side of the protrusion,
wherein
the placing table includes
a pedestal having an annular shape and facing a sucked portion of the diaphragm from below, the sucked portion being sucked by the suction pad, and
a recess recessed downward on an inner diameter side of the pedestal, and
a whole of the protrusion of the diaphragm is located inside the recess in a top view.

2. The diaphragm transfer device according to claim 1 , wherein in a state where the diaphragm is placed on the placing table and not sucked by the suction pad, the diaphragm vertically faces the pedestal via a first gap.

3. The diaphragm transfer device according to claim 2 , wherein
in the state where the diaphragm is placed on the placing table and not sucked by the suction pad, the protrusion vertically faces the recess via a second gap, and
a length of the first gap is equal to or less than a length of the second gap.

4. The diaphragm transfer device according to claim 1 , wherein
the placing table further includes a step having an annular shape and
the step has:
an outer circumferential wall that positions an outer circumference of the diaphragm radially from an outer diameter side; and
a bottom surface that supports the outer circumference of the diaphragm from below.

5. The diaphragm transfer device according to claim 4 , wherein
the placing table is formed with a groove that radially penetrates the step, and
in a state where the diaphragm is positioned on the placing table, a space defined between the diaphragm and the placing table below the diaphragm communicates with an outside of the space through the groove.
