Description

配向紫外线照射机 技术领域
本发明涉及显示技术领域，尤其涉及一种配向紫外线照射机。
 背景技术
液晶显示装置（Liquid Crystal Display，LCD）具有机身薄、省电、无辐射等众多优点，得到了广泛的应用。现有市场上的液晶显示装置大部分为背光型液晶显示装置，其包括液晶显示面板及背光模组。通常液晶显示面板由彩膜（Color Filter，CF）基板、薄膜晶体管（Thin Film Transistor，TFT）基板、夹于彩膜基板与TFT基板之间的液晶（Liquid Crystal，LC）及密封框胶（Sealant）组成。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，通过玻璃基板通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。
通常，TFT基板及CF基板上分别具有一层配向膜，该配向膜与LC接触后，能够使得LC产生一定方向的预倾角，从而给液晶分子提供一个承载的角度（预倾角的大小对LCD的驱动电压、对比度、响应时间、视角等具有重要影响），配向膜的材料通常选用聚酰亚胺（Polyimide，PI）材料，由PI液涂布于基板上所形成。
聚合物稳定垂直配向（Polymer stabilized vertical alignment，PSVA）技术能够使液晶显示面板具有较快的响应时间、穿透率高等优点，其特点是液晶里包含有反应型单体（RM），通过对基板照射紫外光（UV）的方式使液晶中的反应型单体发生反应，在配向膜表面形成聚合物突起，从而在电压和温度的协同作用下使液晶形成预倾角，这一过程称为紫外配向。因此，在液晶配向过程中，紫外线、电场以及反应温度是三个非常重要的因素。
液晶面板的紫外配向过程通过配向紫外线照射机（Ultraviolet Meter，UVM）来实现，当前业界用于紫外配向的紫外线照射机主要是腔体式（chamber），在紫外线照射机中，灯管提供液晶反应所需的紫外光，加热平台（stage）提供液晶反应所需的温度。在实际生产中，需要保证面板在配向过程中其显示区（AA区）的温度保持均匀，因此会在stage上覆盖一块导热板，以保证面板接收到的温度均匀。
现有的配向紫外线照射机通过机械手臂（robot）进行进片和排片的动作，如图1-2所示，进片过程中，在使用机械手臂8将显示面板9运入腔体5内放于加热平台1上时，为了防止显示面板9破裂，需从加热平台1中伸出顶升杆（Lift Pin）2来支撑显示面板9，然后机械手臂8从腔体5内移出，顶升杆2下降，从而将显示面板9放置到加热平台1上。当紫外配向完成后，顶升杆2上升将显示面板9顶起，机械手臂8再次进入腔体5内将显示面板9运出。由于顶升杆2需通过导热板3从加热平台1内升出，因此需要在导热板3上对应开孔，而开孔便会影响到导热板3的温度均一性，因此在导热板3上开孔时需避开显示面板9的显示区。目前量产中针对不同的产品会对应设计不同开孔的导热板，当产品切换生产时需更换对应的导热板。然而，产品切换产线时更换导热板耗时较久（一般需3小时），产能影响大且导热板在长期更换动作中容易变形，影响生产良率。此外，现有的配向紫外线照射机需要预先在stage中设置lift pin孔，设计好之后便无法更改，后续产品的排版设计会受到限制，灵活性差。
