Description

Polarizer peeling machine and method for stripping the same

For the attachment accuracy is insufficient, bubbles appear and the polarizer is scratched, etc. The attached polarizer is peeled off from the glass substrate and then reattached to meet the quality requirements of the LCD.

The conventional method for peeling off the polarizer is: first cutting the front end of the polarizer with a blade into the joint of the polarizer and the glass substrate; and pulling the front end of the polarizer up until the polarizer is separated from the glass substrate. Referring to FIG. 1 , it is a schematic cross-sectional structure of a conventional polarizer peeling machine. The conventional polarizer peeling machine adopts a single roller system, which includes an operation platform 101 and a roller 102. The operation platform 101 is provided with a slit 103 as a polarizing strip peeling position, and the roller 102 is installed under the slit 103, and the polarizer is to be peeled off. The glass substrate 104 slides over the slit 103 on the operation platform 101, and the front end of the polarizer 105 is connected to the roller 102. As the glass substrate 104 slides on the operation platform 101 and the roller 102 rotates in the B direction, The polarizer 105 is separated from the glass substrate 104 and wound around the roller 102. After the polarizer 105 is peeled off, the roller 102 needs to be rotated in the opposite direction in the A direction to remove the polarizer 105 wound on the roller 102, and then the next polarizer peeling operation is performed. The process cannot continuously perform the polarizer stripping operation, and the efficiency is low.
