[0002] The basic structure of polarizing sheet is composed of two layers of tri-acetyl cellulose film (TAC) and a layer of polyvinyl alcohol film (PVA) that can produce polarized light. When natural light passes through the polarizing sheet, the light whose vibration direction is perpendicular to the transmission axis of the polarizing sheet will be absorbed, leaving only the polarized light whose vibration direction is parallel to the transmission axis of the polarizing sheet to pass through, thereby realizing the control of the polarization direction of the light beam.

[0003] In the production and processing process of polarizing sheet, cutting is a crucial link, which directly affects the dimensional accuracy and appearance quality of the finished polarizing sheet. However, in actual operation, the cut polarizing sheet is often directly stacked on the cutting table. This disordered stacking method not only may cause scratches or damage between the polarizing sheets, affecting product quality, but also brings great inconvenience to subsequent arrangement work. When a batch of polarizing sheet is cut, the staff needs to spend a lot of time and effort to arrange these scattered polarizing sheets one by one, and rearrange them according to the specified order and direction, so as to facilitate subsequent packaging and transportation.
