  • Patent number: 5667624
    Abstract: The present invention relates to a polarization plate to a surface of a liquid crystal cell in a manufacturing process of a liquid crystal panel, where a rotary table is disposed with loading domains for the liquid crystal cell, with each domain sequentially moving to carry-in, cleaning, gluing and carry-out stations.The cleaning mechanism serves to cause an elastic plate to be pushed to the surface of the liquid crystal cell, thereby removing foreign objects.The gluing mechanism serves to cut the polarization plate on the carrier tape to a predetermined length, to thereby allow the same to be a polarization plate chip, which is in turn absorbed and supported by the glue head. The polarization chip is now torn apart from the carrier tape to thereby be glued to the surface of the liquid crystal cell.By this, process of picking up the polariation plate can be shortened and the position of the polarization plate can be determined in a state of the polarization plate being absorbed and supported by the glue head.
