Abstract

A production process for robotically removing a protective film from the active face of a cathode ray tube (CRT) uses a workstation including a clamping apparatus for the CRT, monothane wheels for freeing the film edge, and robotic grippers for stripping and removing the film. In operation, a CRT 10 is delivered by a robot to a CRT support 11 which includes an air-bearing table. This assembly then translates to the stripping station and lowers so that a lug on each corner of the CRT drops over a corresponding dowel pin 12 (only one shown). The air-bearing table permits slight lateral movement during this operation to allow for mechanical tolerances. The CRT is then clamped on the corner lugs, and the CRT support drops, translates away from the CRT and rises to its original position, ready to receive another CRT.

Robotic Removal of Protective Film From CRT Face

A production process for robotically removing a protective film from the active face of a cathode ray tube (CRT) uses a workstation including a clamping apparatus for the CRT, monothane wheels for freeing the film edge, and robotic grippers for stripping and removing the film. In operation, a CRT 10 is delivered by a robot to a CRT support 11 which includes an air-bearing table. This assembly then translates to the stripping station and lowers so that a lug on each corner of the CRT drops over a corresponding dowel pin 12 (only one shown). The air-bearing table permits slight lateral movement during this operation to allow for mechanical tolerances. The CRT is then clamped on the corner lugs, and the CRT support drops, translates away from the CRT and rises to its original position, ready to receive another CRT. At the stripping station, the stripping operation commences with a bank of monothane stripping wheels 13 (only one visible) which are set rotating and moved across the tube edge, lifting the edge of the protective film. This film edge is grasped by one or more of a group of robotic grippers 14 (only one visible) which, after checking that the film has been successfully gripped, drop slightly and move across the face of the CRT, stripping as they do so. When the grippers have moved far enough to completely remove the film from the CRT, the grippers are opened which usually leaves the film adhering to some of...
