Patent attributes
A substrate gripping hand includes: a base plate wherein a center line and gripping position are prescribed; at least one fixed claw capable of mating with a substrate edge in the gripping position and provided at a base plate distal end side; a movable claw having an acting portion acting on a substrate edge in gripping position and movable back-and-forth on center line; a pusher having an acting portion acting on an edge lower than the substrate center in a perpendicular orientation and movable back-and-forth parallel with the center line; and an actuator for moving the movable claw and pusher. The pusher acting portion is positioned more to the distal end side than the movable claw acting portion such that the substrate is grasped by the movable claw joint operation and the fixed claw after the substrate is brought to gripping position by the pusher moving forward toward the distal end side.
