Abstract
A method for transferring a thin plate is provided, in which three or more grasping claws of a transfer arm grasp the periphery of the thin plate in order to transfer it to a predetermined transfer position, and three or more holding claws hold the periphery of the thin plate in the transfer position. The transfer arm rotates about a shaft which is in a direction of a vector sum of a first vector perpendicular to a surface of the thin plate before transfer, and a second vector perpendicular to the surface of the thin plate after the transfer, to transfer the thin plate with changing the posture thereof.
Claims7
A method for transferring a thin plate by changing a posture of said thin plate, comprising:
- rotating a transfer arm that holds said thin plate about a shaft which extends in a direction of a vector sum of a first vector perpendicular to a surface of said thin plate before transfer, and a second vector perpendicular to said surface of said thin plate after the transfer, when the magnitude of said first and second vectors is equal to each other to change said posture of said thin plate, the rotation of the transfer arm being such that said shaft is positioned under said thin plate during the entire transfer.
An apparatus for transferring a thin plate by changing a posture of said thin plate, comprising:
- a transfer arm for grasping said thin plate, said transfer arm being attached to and rotatable about a first end of a shaft which extends in a direction of a vector sum of a first vector that extends perpendicular to a surface of said thin plate before transfer, and a second vector that extends perpendicular to said surface of said thin plate after the transfer, when the magnitude of said first and second vectors is equal to each other, such that during the entire transfer said shaft is positioned under said thin plate.
