▎ 摘 要
NOVELTY - The utility model relates to a touch screen is etching a conductive layer of graphene device, the output end of the high frequency short-pulse laser is arranged with a light gate, the output end of the brake is provided with a beam expander, the output end of the expander is arranged with a 45 degrees total reflection mirror, the output end of the 45 completely reflecting mirror is orderly arranged with a dynamic focusing mirror and a scanning field lens, the scanning field lens is opposite is set with the other one side of the blowing device, a working platform for one side of the working platform, the working platform is equipped with a dust collecting device. A function of high frequency pulse laser with different wavelength as the laser source, a touch screen product with graphene as conductive layer material for laser etching the graphene conductive layer on the high frequency short-pulse laser is a gasification so as to reach the aim of etch through high-precision dynamic focusing mirror and a galvanometer, the etching ranges from 500 mm asterisk 500 mm, process is pollution-free, linear stable, the touch screen electronic product.
