[0002] A polarizing plate is made of a film with highly oriented polymer molecules, which are linear and naturally arranged parallel to the film surface. Their production process usually involves stretching the molecules along the same axis and fixing them so that they can be parallel to each other and perpendicular to the surface. The film thus produced exhibits unique properties for light, allowing only light oscillating in a specific plane to pass in a certain direction.

[0003] In the prior art, when pasting a polarizing plate, a suction assembly such as a suction cup is often used to suck the polarizing plate to the surface of the electronic screen to be pasted, then the suction cup is removed, and a pressing device is used to press the polarizing plate to eliminate air bubbles between the polarizing plate and the object to be pasted.
