A tearing method for tearing a polarizing plate, including: after a tear-initiation edge of a polarizing plate defectively attached on a liquid crystal panel is torn away from the panel, turning on a pneumatic maintaining device to keep the tear-initiation edge at a torn-away state; moving the pneumatic maintaining device and a tearing platform such that the tear-initiation edge can be located in a tearing assembly; and clamping the tear-initiation edge in the tearing assembly and further tearing the polarizing plate by the relative movement between the tearing platform and the tearing assembly. The present disclosure further provides a tearing apparatus for tearing the polarizing plate. The tearing method and device allows the polarizing plate to be torn semi-automatically, improves the controllability of the tearing process of the polarizing plate, and further improves the yield rate of the panel as well as reduces the industry safety risks. |
