Description

配向紫外线液晶照射装置、水冷套管
【技术领域】
本发明涉及液晶面板制造技术领域，特别涉及一种配向紫外线液晶照射装置、还涉及一种水冷套管。
【背景技术】
HVA光配向技术是指在给基板加电压的情况下，通过紫外光照射促使基板内的单体（monomer）与基板表面的配向膜分子链（PI Side Chain）反应，进而达到液晶配向目的。HVA光配向技术已广泛应用于高世代TFT-LCD行业中。
配向紫外线灯管（UVM Lamp）发射出的紫外光若不经过任何过滤直接照射至液晶基板上，会对液晶分子进行破坏，导致配向异常，配向紫外线灯管发出的紫外光的波长在200~500nm波段均有，320nm以下的紫外光对液晶分子存在不同程度破坏影响，需使用石英材料的紫外光滤光片（UV cut filter）进行过滤。
请参阅图1，图1是现有技术中液晶面板进行配向的工作示意图。
如图1所示，在G8.5代液晶面板产线上，液晶面板3的尺寸为2200×2500mm，而紫外光滤光片需由多个小块的紫外滤光片2拼凑而成，每一小块的紫外滤光片2的尺寸为32×28mm，配向紫外线液晶照射装置1发出的紫外光经由紫外光滤光片2滤光后照射至液晶面板3。
多个小块的紫外滤光片2拼凑容易造成推挤破裂（如图2中所示的A处），造成产能损失且漏光后会造成产品大量报废，破裂不容易被发现，并且，多个小块的紫外滤光片2拼凑容易有堆叠性漏光（如图2中所示的B处）不容易发现，确认漏光至少需要1天的时间，此外，小块的紫外滤光片使用寿命较短，更换周期一般为2~3年。
基于以上原因，在生产过程中需要经常停机检查漏光以及破损状况并相应更换小块的紫外滤光片。

如图3所示，本发明提供一种配向紫外线液晶照射装置10，其发出的紫外光经过滤后直接射向液晶面板20，与现有技术相比较，其无需通过小块的紫外滤光片2进行过滤，避免了利用多块片状紫外滤光片2进行滤光容易造成推挤破裂或堆叠漏光的问题。
具体而言，请一并参阅图4和图5，其中，图4是图3中所示的配向紫外线液晶照射装置的局部放大立体结构示意图，图5是图3中所示的配向紫外线液晶照射装置的截面放大结构示意图。
如图4和图5所示，本发明提供的配向紫外线液晶照射装置10主要包括水冷套管100、灯管200、红外滤光层300、紫外滤光层400以及灯罩500。
其中，水冷套管100包括间隔设置的内管110和外管120，该内管110和外管120可采用秀明的石英材料制成。在本发明实施例中，内管110的管径小于外管120的管径，该内管110和外管120可为空心圆柱状，在其他实施例中，该内管110和外管120亦可为空心的椭圆柱状。
在优选实施例中，水冷套管100还包括第一间隔物和第二间隔物、入水口130、出水口、入水管140以及出水管。
其中，第一间隔物将内管110与外管120平行间隔。第二间隔物将红外滤光层300与内管110和外管120平行间隔，优选地，第二间隔物将红外滤光层300间隔于内管110和外管120的中间位置处，该第二间隔物可为支架、球体等，可通过粘接或其他方式固定于内管110、外管120或红外滤光层300上。

在优选实施例中，第一间隔物可为设于内管110和外管120的第一端部和第二端部的封板，本领域技术人员容易想到，该封板为环圈状，封板与内管110和外管120相连接，封板、内管110以及外管120形成冷却物流动空间，其中，冷却物可为冷却水或其他冷却质。
灯管200设于内管110的内部，在本发明实施例中，灯管200为圆形灯管，在其他实施例中，灯管200亦可为椭圆形灯管，灯管200的数量也不限于一个，可以是两个或多个。

反光罩500呈围绕水冷套管100的弧形状，将配向紫外线液晶照射装置10发出的光反射至液晶面板。
综上所述，本领技术技人员容易理解，区别于现有技术的情况，本发明提供的配向紫外线液晶照射装置10及其水冷套管100由于在外管120上设置有紫外滤光层400，解决了现有技术中利用多块片状紫外滤光2片进行滤光容易造成推挤破裂或堆叠漏光的问题，并且可避免片状紫外滤光2破损漏光导致产品报废，此外，紫外滤光层400比片状紫外滤光2使用寿命长，可长期使用不需做任何更换，降低了生产成本，减少了需停机检查导致产能损失以及人力浪费。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
