    • 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.
    • 一种用于撕裂偏振片的撕裂方法,包括:在缺陷地附着在液晶面板上的偏振片的撕裂起始边缘从面板撕开之后,打开气动保持装置,使撕裂起始边缘保持在 撕毁状态 移动气动维持装置和撕裂平台,使得撕裂起始边缘可以位于撕裂组件中; 并且将撕裂起始边缘夹紧在撕裂组件中,并通过撕裂平台和撕裂组件之间的相对运动进一步撕裂偏振片。 本公开还提供了一种用于撕裂偏振片的撕裂装置。 撕裂方法和装置允许偏光板半自动撕裂,提高偏光板撕裂过程的可控性,进一步提高面板的成品率,降低行业安全隐患。
