SYSTEM FOR DETECTING SURFACE OF A COATED CONDUCTIVE SUBSTRATE

원문 (중국어)

A system for detecting an edge of a substrate, comprising a coated assembly. The coated assembly includes a conductive substrate having at least one edge portion and a dielectric coating coupled along the conductive substrate, the dielectric coating covering the at least one edge portion of the conductive substrate. The system also includes a conductive tool configured to interact with the coated assembly and a substrate sensing system. The substrate sensing system includes a power source coupled with the conductive tool, the coated assembly, and an electrical circuit including the power source and the coated assembly and a sensor configured to sense a change between an open configuration and a closed configuration of the electrical circuit. In an open configuration the conductive tool is engaged with the coated assembly and disengaged from the conductive substrate and in a closed configuration the conductive tool is engaged with the conductive substrate.
