Abstract
A method which is capable of completely separating a plate member with a large area without using a peeling member and eliminating a possibility of permanent deformation on the plate member. A plurality of suction pads are suckingly disposed on a surface of a topmost plate member in a substantially lattice shape. Then, while the topmost plate member is held by the suction pads disposed in a zigzag shape among the suction pads disposed in the substantially lattice shape, the topmost plate member is lifted by the remaining suction pads. Finally, the suction pads holding the topmost plate member are lifted.
Claims19
A method of separating a plate member for separating a topmost plate member from laminated plate members, the method comprising:
- a first step of arranging a plurality of suction devices substantially in a lattice shape to apply a suction force on a surface of a topmost plate member, said suction devices including a plurality of first and second suction devices;
- a second step of holding the topmost plate member by the plurality of first suction devices, which are arranged in a zigzag pattern within the substantially lattice shaped arrangement of the suction devices, and lifting the topmost plate member by the plurality of second suction devices, wherein the second suction devices are mutually exclusive of the first suction devices;
- and
- a third step of lifting the plurality of first suction devices holding the topmost plate member at the second step.
A method of separating a plate member for separating a topmost plate member from laminated plate members, the method comprising:
- a first step of forming a first inclined face continuous to a lower face from an end face of a plate member at a corner portion on a lower side and forming a second inclined face continuous to an upper face from the end face of the plate member at a corner portion on an upper side;
- a second step of arranging suction devices to apply a suction force on a center portion and end portions of the topmost plate member;
- a third step of blowing wind to the end face of the plate member, holding the topmost plate member by the suction device arranged at the center portion of the plate member, and lifting the topmost plate member by remaining ones of the suction devices;
- and
- a fourth step of lifting the suction device holding the topmost plate member at the third step while blowing the wind to the end face of the plate member.
