Automatic Apparatus of Controlling Concentration of Dyeing Composition For Polarizer and Automatic Controlling Method thereof

摘要

The present invention will automatically check the concentration of the dyeing liquid of the dyeing process of the polarizing plate used in the flat panel display (FPD) the equipment. Relates to the concentration of the dye solution, the concentration of the dye composition in real time using a spectroscope to an apparatus and method for the automatic management. The device is connected to a dye liquid tank in a manufacturing process of the polarizer, the analysis device comprising a spectrometer for analyzing the dye concentration in the dye composition tank and the dye composition according to the analysis result of the analysis device and a further supply for replenishing dye composition. In addition, the administration method is the storage tank for the lack of staining solution dye composition according to the analysis result of step and the spectrometer using a spectroscope to analyze the concentration of each dye composition present in the dye storage tanks for the dyeing process of the polarizing plate production process supplied to a step of adjusting the dye composition.
