Abstract

This invention relates to an auto-etching unit for TFT-LCD glass which comprises an etching tank using a corrosive treatment solution such as hydrofluoric acid to etch the glass substrate; a first fast washing tank to clean the treatment solution etching substrate on the glass substrate; a second fast washing tank to clean the etching substance for the second time; and a drying tank to dry the glass substrate. The invented unit further comprises a supplying tank to supply hydrofluoric acid or similar mixed reagent solution (named treatment solution thereafter); two sedimentation tanks to alternately sediment the used treatment solution to regenerate the treatment solution; and two supplying units to alternately supply original liquid of the treatment solution. A porous bubbling unit capable of ejecting nitrogen or similar gas (named nitrogen hereafter) and punching plates to guide and disperse the gas bubbles are concurrently disposed on the bottom of the etching tank so that the bubbling unit can supply nitrogen to homogeneously clean the surface of the glass substrate.
