Polarizer removing device and method of using it

摘要

The present invention provides a polarizer removing device and a method of using it. The polarizer removing device comprises a supporting unit for supporting a panel, a clamping-removing unit for clamping a polarizer and removing the polarizer from the panel, and a pressurizing unit for exerting a pressure onto the panel during the removing of the polarizer. According to the polarizer removing device, a uniform force is exerted onto the polarizer during the removal thereof. As a result, it is above to prevent the polarizer from being broken, thereby to facilitate the operation, improve the production efficiency and save an adhesive tape.

1. A polarizer removing device, comprising a supporting unit for supporting a panel, a clamping-removing unit for clamping a polarizer and removing the polarizer from the panel, and a pressurizing unit for exerting a pressure onto the panel during the removing of the polarizer;
wherein the clamping-removing unit comprises a cylindrical winding drum, on which a clamping mechanism for clamping the polarizer is arranged, the winding drum being configured to be rotated so as to wind the polarizer clamped by the clamping mechanism onto an outer surface of the winding drum; wherein a groove is provided in the outer surface of the winding drum and extends in a direction identical to an extension direction of the winding drum; wherein the clamping mechanism comprises a clamping block and a power unit, the clamping block being driven by the power unit so as to move toward an interior of the groove and cooperate with the groove, thereby to clamp the polarizer; wherein the power unit is provided within the winding drum, and comprises a guiding plate, a sliding block cooperating with the guiding plate, and a cylinder; wherein a piston rod of the cylinder is connected to the sliding block and has an axis parallel to an axis of the winding drum; wherein an upper end of the sliding block extends through a via-hole at a bottom of the groove and is connected to the clamping block; and wherein the piston rod is configured to move the sliding block along the guiding plate toward the cylinder, so that the sliding block moves the clamping block toward the interior of the groove.
