Device for holding plate-shaped body in frame passing before coating unit

摘要

Plate bodies (5) are held in a frame (2) by spring clamps (6) which fit inside openings (44) in the frame. The clamps can be moved from a starting position (PA) where they are completely free from the frame into a work position where the clamping edge (18) is raised above the plate in the non-clamp phase (PE) and then forced down into the clamp position (PB) by spring (16) when the robot finger (25) is removed. The edge (18) is balanced on a pivot edge (10) fixed to the circular body (8) which rotates in the grooves (24) in ring nut (24). The plate is also held at the back by a tension element (46) which is clamped into position by gripping devices (59b) which can move horizontally to pull stamps (52) onto the plate or alternatively release the pressure of the stamp.
