AIR KNIFE STRUCTURE OF LCD PANEL DRYING DEVICE, ESPECIALLY CONCERNED WITH IMPROVING UNIFORMITY OF AIR JET THROUGH DISCHARGE PORTS OF AIR KNIFE WHILE MINIMIZING LOSS OF AIR

摘要

PURPOSE: An air knife structure of an LCD(Liquid Crystal Display) panel drying device is provided to improve the uniformity of air jet through discharge ports of an air knife while minimizing loss of air due to exposing holes generated at assembling bolt holes, thereby effectively removing a cleaning solution and particles from a surface of an LCD panel. CONSTITUTION: An air inlet block(110) is formed in a square shape having a space inside, and has an air inlet pipe(111) at both ends to flow compressed air supplied from a compressor into the air inlet block, and has a plurality of outlet holes(112) formed at a lower surface for flowing out the air. An air jet block(120) has a plurality of air guide passages(121) connected with the outlet holes of the air inlet block, has orifice paths(122) extended from the air guide passages and bent in multi-stages with a change in width, and jet holes(123) formed at ends of the orifice paths.
