VARIABLE PNEUMATIC PRESSURE SUPPLY DEVICE OF A GRINDING BELT FOR CLEANING DISPLAY PANELS, CAPABLE OF ACCURATELY CONTROLLING THE AREA OF PNEUMATIC PRESSURE

摘要

PURPOSE: A variable pneumatic pressure supply device of a grinding belt for cleaning display panels is provided to enable the easy control of pneumatic pressure applied on a grinding belt according to the standard of the display panel in cleaning or grinding process of the display panel.;CONSTITUTION: A variable pneumatic pressure supply device of a grinding belt for cleaning display panels comprises a pneumatic pressure feeding unit(100). The pneumatic pressure feeding unit comprises an air guide block(110), a porous pad(130), a pad mounting block(140), a pair of variable sidewalls(150), a side wall adjusting unit(160). The porous pad lets the pneumatic pressure of an air chamber(120) of the air guide block through a lower part. The pad mounting block covers the rim of the porous pad to fix the porous pad with the lower part of the air guide block. The side wall adjusting unit is installed outside the variable sidewalls to change the distance between the variable sidewalls according to the width of the display panel.;COPYRIGHT KIPO 2010
