AUTOMATED FILM PICKUP AND PLACEMENT METHOD FOR INSULATING GLASS UNITS

摘要

A method of automatically mounting a sheet from a cutting table onto a spacer frame of an insulating glass unit begins with identifying a position and orientation of a specified sheet on the cutting table and moving a robotic sheet pickup apparatus to a corresponding position to that identified for the sheet. An edge of the specified sheet is lifted off of the table, beginning with mechanical suction that brings a corner of the sheet to within proximity of a primary vacuum suction of the pickup apparatus. In particular, the pickup apparatus may have a substantially planar platen with a set of channels coupled to a vacuum source. Once the sheet is fully picked up by vacuum suction, the sheet is laid upon a top surface of a tilt table, which can be simply the platen inverted. The table (or platen) is tilted to bring a corner of the sheet to abut against physical fences. Once the position and orientation of the sheet is so known, the sheet is oriented to correspond to a frame, and attached thereto.

1. A method of mounting a sheet onto a spacer frame of an insulating glass unit, the method comprising:
identifying a position and orientation upon a cutting table of a specified sheet to be mounted, wherein the sheet is of any arbitrary size; moving a sheet pickup apparatus to a position corresponding to the identified position and orientation of the specified sheet; lifting a corner of a specified sheet off of the cutting table; lifting an edge of that sheet off the cutting table; lifting the remaining portion of the sheet off the cutting table so it lies adjacent to a lifting surface; inverting the sheet pickup apparatus so that the sheet lays on the lifting surface; moving the sheet to abut a fence on the lifting surface; rotating the sheet pickup apparatus to align the sheet with a frame; and attaching the sheet to the frame.
