Patent ID: 8701734

Claim:
A separating apparatus for separating a supporting plate from a substrate to which the supporting plate has been attached, comprising: a plurality of gripping devices configured to grip an outer peripheral end of the supporting plate, each of the plurality of gripping devices configured to grip the supporting plate; a plurality of cylinders, wherein each cylinder is configured to individually move each gripping device in a linear horizontal direction toward or away from the supporting plate; and a sucking device configured to adhere to the supporting plate by suction, wherein the surface of the supporting plate is attached to the substrate, wherein the outer peripheral end of the supporting plate has a chamfered portion, wherein each of the gripping devices comprises a clamp having a vertical surface facing the supporting plate and a claw having a surface declined away from the vertical surface toward the supporting plate to grip the chamfered portion of the outer peripheral end, wherein the plurality of gripping devices is configured to grip the outer peripheral end of the supporting plate to which the sucking device has adhered by suction, and wherein each of the cylinders is capable of individually controlling each of the gripping devices comprising a clamp so that a displacement angle of the clamp with respect to a direction orthogonal to the surface of the supporting plate is capable of being set to a predetermined angle.
