▎ 摘 要
NOVELTY - The device has an optical shutter (2) whose light output end is provided with a beam expander (3). The output end of the expander is arranged with a 45 degrees total reflection mirror (4). The output end of the reflection mirror is provided with a dynamic focusing mirror (5) and a scanning field lens (6). The scanning field lens is provided with a blowing device (7). A working platform (10) is equipped with a dust collecting device (9). USE - Device for etching graphene conductive layer on touch screen. ADVANTAGE - The device is pollution-free and stable, and has high working precision. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for etching graphene conductive layer on touch screen. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the conductive layer etching device.
