Abstract
The utility model relates to a device used for TOL touch and OGS touch upper conducting film layer laser etching. Lasers emitted by a laser device enter a beam expander through an optical shutter. Laser beams enter a total reflection lens set adjusting optical path after being expanded and collimated by the beam expander. The lasers are all reflected to a vibration lens system and are accurately controlled to be focused on a conducting film of glass through a telecentric field lens. A focus light spot ranges from 20 micros to 40 micros. The laser device and the vibration lens system are in data communication through a communication system and an industrial personal computer and convert a scanned image into digital signals. The image is converted on a piece to be machined, wherein the piece to be machined needs etching and is absorbed on a vacuum absorption platform. A CCD counterpoint observing system is used for shooting an imported localizer, capturing a target and controlling machining. After one unit is subjected to laser etching, a next unit is moved by the vacuum absorption platform, the lasers start machining again, and the etching of the whole processed image is achieved through repeating of the process. According to the device used for the TOL touch and OGS touch upper conducting film layer laser etching, the machining method is concise, the machining efficiency is high, and consumable items are not needed.
