Abstract

Protective expanded-polystyrene foam sheet material is removed from the screen of a CRT by cutting it in two along a central line, bunching the two separated halves, and individually gripping the two portions of material and pulling them apart off the screen. In operation, protective expanded polystyrene foam sheet material is removed from faceplates of CRTs as a continuous process using automatically operated apparatus. Each CRT is placed in turn by a robot at a 'place' station from where it is moved to a 'workstation' for removal of the sheet material, and thereafter to a 'pick' station for removal also by a robot. The figure shows a CRT at the workstation for removal of the protective sheet material.

Method of Robotically Removing Protective Foam From a CRT Face

Protective expanded-polystyrene foam sheet material is removed from the screen of a CRT by cutting it in two along a central line, bunching the two separated halves, and individually gripping the two portions of material and pulling them apart off the screen. In operation, protective expanded polystyrene foam sheet material is removed from faceplates of CRTs as a continuous process using automatically operated apparatus. Each CRT is placed in turn by a robot at a 'place' station from where it is moved to a 'workstation' for removal of the sheet material, and thereafter to a 'pick' station for removal also by a robot. The figure shows a CRT at the workstation for removal of the protective sheet material. The mechanism for removal of the material includes two linear arrays of vacuum-operated suction cups 3 and between which is located an elongated hot air cutter 4. Initially, the arrays of suction cups are moved into contact with the sheet material, one on each side of a notional central line across the material. In this position the cups are shown as labelled 3.1. The vacuum is operated and with the material attached, the arrays of cups are moved away from the CRT back towards their original position, drawing the sheet material towards the hot air cutter where it is eventually cut in two along the central line. The two arrays of suction cups, with the respective portions of sheet material still attache...
