技术领域Technical field
本申请涉及液晶显示技术领域，特别涉及一种偏光板限位机构以及偏光板限位机构的控制方法。The present application relates to the technical field of liquid crystal display, in particular to a polarizing plate limiting mechanism and a control method of the polarizing plate limiting mechanism.
背景技术Background technique
这里的陈述仅提供与本申请有关的背景信息，而不必然地构成现有技术。The statements here only provide background information related to the present application and do not necessarily constitute prior art.
液晶面板偏光板贴附制程中，受偏光板清扫部清扫滚筒之间的间隙不佳、偏光板表面材质变异、对位平台对位速度不佳等影响，易导致偏光板对位失败。采用三边（两个短边+一个长边）对位方式进行偏光板对位，由于三边对位方式只有三边限位，若偏光板表面材质变异，导致摩擦系数变化，或者长边对位气缸速度不佳，导致偏光板长边在靠位时发生歪斜，偏光板进入对位平台发生歪斜，长边对位柱无法进行靠位，相机的镜头无法抓取偏光板，容易导致偏光板对位失败。During the process of attaching the polarizing plate of the liquid crystal panel, the polarizing plate cleaning section is affected by poor gaps between the cleaning rollers of the polarizing plate, surface material variation of the polarizing plate, and poor alignment speed of the alignment platform. The three-sided (two short sides + one long side) alignment method is used for polarizing plate alignment. Since the three-side alignment method has only three-sided positioning, if the polarizer surface material changes, the friction coefficient changes, or the long side alignment The poor speed of the positioning cylinder causes the long side of the polarizer to skew when it is seated. The polarizer enters the registration platform and skews. The long-side registration post cannot be seated. The camera lens cannot grab the polarizer, which is easy to cause the polarizer. Alignment failed.
