LASER MARKING APPARATUS AND METHOD FOR HANDPHONE KEYPAD

摘要

PURPOSE: A laser marking apparatus for a cell phone keypad and a method thereof are provided to reduce working burden and cleaning time, since laser marking and cleaning are performed together when multiple cell phones are placed on a tray. CONSTITUTION: A laser marking apparatus for a cell phone keypad comprises a laser marking unit(110), and a CO2 cleaning unit(120). The laser marking unit emits laser on a cell phone keypad to mark characters or numbers. The CO2 cleaning unit sprays CO2 particles on a marked site and removes residue. The laser is used among an ultraviolet laser, a green laser, an infrared laser, and a CO2 laser.
