Technical Field
The invention relates to the field of laser cutting, in particular to a cutting edge detection device and laser cutting equipment.
Background
The laser cutting can replace the traditional diamond cutter processing, and is widely used in the glass material removing and forming process. In laser glass cutting, when a laser focused beam enters the surface of glass from the edge of the glass to start cutting, the focused beam is refracted and reflected on the end surface and the lower surface of the glass with a certain thickness, and unnecessary light with certain energy can damage the upper surface of the glass.
