Green Sheet Pick Up Tool

This article concerns a tool for handling unfired ceramic sheets without causing damage or distortion to the sheet corners or edges. The tool features a receiving plate to which a handle, vacuum suction and gas release means are added for receiving, retaining and releasing the uncured ceramic sheet.

In the course of manufacturing ceramic sheets, it becomes necessary to handle the ceramic in the unfired state, a state in which it can be easily distorted or damaged. This article concerns a tool for handling such uncured ceramic sheets which avoids damage.

As shown in the figures and with particular reference to Fig. 1, tool 1 includes a base plate 2 for receiving an uncured ceramic sheet (not shown). Base plate 2 is formed by two rectangular polycarbonate sheets 3 and 4 which, as better seen in Figs. 2 and 3, are contoured to accept the uncured sheet without contact to any patterning which may exist on the sheet. Base plate 2 is also provided with a metallic plate 5, e.g., aluminum, atop polycarbonate sheets 3 and 4 for stiffening purposes. A~ seen in Fig. 1, a vacuum line 6 and a gas line 7, e.g., nitrogen, are provided at base plate 2 to retain and release the ceramic substrate, as desired. As best seen in Fig. 3, polycarbonate sheets 3 and 4 are provided with channels 8 and 9, respectively, for applying vacuum and release gas alternately to the ceramic sheet when it is respectively picked up and released. With reference to Fig. 1, tool 1...
