Description

液晶面板的裂片装置及方法
技术领域
本发明涉及液晶面板领域，尤其涉及一种液晶面板的裂片装置及方法。
背景技术
光配向是指在给基板施加电压时，通过紫外光照射而使面板内的单体反应，以达到液晶配向的目的。而为了给基板施加电压，必须将CF（Color Filter，彩色滤光片）基板的余料切除，以露出TFT（Thin Film Transistor，薄膜场效应晶体管）基板两端的金属线。即先通过切割机在CF基板上划出一切割线，然后通过裂片治具使得切割线外侧的CF基板余料从CF基板上脱落，从而露出TFT基板两相邻侧面的端子区。
如图1所示，图1是现有技术裂片治具的截面结构示意图。该裂片治具包括上裂片101及下裂片102。需要裂片的液晶面板包括TFT基板201、CF基板202，该TFT基板201和CF基板202之间夹设有液晶而形成显示区203，显示区203的外围均设有框胶204，该框胶用于将液晶密封于显示区203内及连接TFT基板201和CF基板202。该液晶面板的裂片步骤为：先将切割机在CF基板202上划出切割线，该切割线位于CF基板202设置有框胶204的外端处；然后将上裂片101紧贴液晶面板的TFT基板201，下裂片102紧贴液晶面板的CF基板202，将紧贴CF基板202的下裂片102端部向上裂片101靠近（即沿A箭头所示的方向运动）而将CF基板202的外端部分沿切割线处折断，从而CF基板202的外端部分可从液晶面板上脱离，最后下裂片101将CF基板202的外端部分吸附走。
上述裂片治具中，由于上裂片101及下裂片102仅两端夹持，因此在下裂片102向上裂片101靠近时，下裂片102的中间将呈弯曲状，从而使得两裂片的端部之间的距离与两裂片中间部分的距离不一致，造成裂片异常，影响了液晶面板的良率。

本发明通过第二夹持机构40夹持上裂片10和下裂片20的中间部分，从而使得该裂片装置在对液晶面板进行裂片时，可以调节第二夹持机构40，将上裂片10和下裂片20的中间部分紧贴液晶面板而不会弯曲，保证了上裂片10和下裂片20各个部分之间的距离的误差在0.05mm以下，从而使得裂片正常，提高了液晶面板的良率。
进一步的，结合参照图3及图4，图3是本发明液晶面板的裂片装置中第二夹持机构与液晶面板的结构示意图；图4是本发明图3所示液晶面板的裂片装置中第二夹持机构夹紧液晶面板的状态示意图。上述第二夹持机构40包括平行设置的上夹持板41和下夹持板42。在本发明一实施例中，该第二夹持机构40中上夹持板41与下夹持板42之间的距离可以是固定的。该距离可以设置为略大于或等于上裂片10、下裂片20的厚度与液晶面板的厚度之和。该上夹持板41紧贴上裂片10设置，下夹持板42紧贴下裂片20设置。在本发明另一实施例中， 该第二夹持机构40中上夹持板41与下夹持板42之间的距离是可调的。例如，该实施例中第二夹持机构40还包括伸缩装置43及控制伸缩装置43运动的控制器（图中未示出），所述伸缩装置43包括固定件431及活动件432。所述固定件431与上夹持板41连接，活动件432与下夹持板42连接，或者固定件431与下夹持板42连接，活动件432与上夹持板41连接。通过控制器调节伸缩装置43运动，从而可调节上夹持板41与下夹持板42之间的距离。优选地，该伸缩装置为气缸，当然也可以为其他起到同等作用的伸缩装置。
进一步的，上述第二夹持机构40还包括用以调节上夹持板41及下夹持板42之间距离的辅助调节件433。当上夹持板41与下夹持板42之间的距离通过控制器而夹紧时，为了提高上夹持板41与上裂片10以及下夹持板42与下裂片20的贴紧度，可以通过该辅助调节件433，对上夹持板41与下夹持板42之间的距离进行微调。
进一步的，一实施例中，上述辅助调节件433是设置在固定件431上的螺旋杆，该螺旋杆与固定件431上设置的螺纹孔配合，通过旋转螺旋杆上的螺盖，可以调节固定件431与活动件432之间的距离，即调节上夹持板41与下夹持板42之间的距离。另一实施例中，上述辅助调节件433也可以包括呈“[”形的夹合部及设置在夹合部上的螺旋部，所述螺旋部穿过夹合部的顶端，且与夹合部的底端将上夹持部41与下夹持部42夹紧。通过转动螺旋部，从而可以调节螺旋部与夹合部的底端之间的距离，即对上夹持部41与下夹持部42之间的距离。
进一步的，上述第一夹持机构30包括设置在上裂片10及下裂片20两端部的活动夹具30a和30b，以活动夹具30a为例，该活动夹具包括基座31、设置在所述基座31两端上的马达32及与所述马达32的输出轴连接的固定部33，该固定部33分别与上裂片10与下裂片20的端部连接。
进一步的，上述第二夹持机构40为两个以上，且间隔设置。由于上裂片10和下裂片20的长度均较长，例如2.9m，所以通过设置多个第二夹持机构40，间隔设置在上裂片10和下裂片20的中间部分，用以夹紧上裂片10和下裂片20。本实施例中，可以将裂片分为三等分，其中处于中间等分的裂片即为上裂片10和下裂片20的中间部分。
上述裂片装置用于对液晶面板进行裂片，如图1所示，该液晶面板被夹持在上裂片10和下裂片20之间，然后再调节第一夹持机构30，使得该下裂片20的端部向上裂片10靠拢，从而可以将CF基板外端部分从液晶面板上沿切割线处折断。同时，调节第二夹持机构40，用以夹紧上裂片10和下裂片20的中间部分，从而使得在下裂片20的端部向上裂片10靠拢时，上裂片10和下裂片20之间的距离整体的误差为0.05mm，提高了液晶面板的良率。
参照图5，图5是本发明液晶面板的裂片方法较佳实施例的流程示意图。该液晶面板的裂片方法包括以下步骤：
步骤S10、提供一裂片装置，其包括上裂片、下裂片、夹持上裂片和下裂片两端部的第一夹持机构及夹持上裂片和下裂片的中间部分的第二夹持机构；
提供一裂片装置，该裂片装置可参照前面所述及参照图1-4，在此就不再赘述。
步骤S20、利用切割机在液晶面板的CF基板形成切割线；
步骤S30、将形成切割线的液晶面板置于上裂片与下裂片之间；
步骤S40、调节第一夹持机构，将CF基板的外端部分从液晶面板上沿切割线折断，同时调节第二夹持机构，以夹紧上裂片和下裂片的中间部分。
先通过切割机在液晶面板的CF基板对应液晶面板显示区的外端形成切割线。然后将形成切割线的液晶面板置于上裂片10和下裂片20之间，即液晶面板的TFT基板紧贴上裂片10，液晶面板的CF基板紧贴下裂片20。调节第一夹持机构30，使得下裂片20的端部向上裂片10靠近，从而将CF基板的外端部分从液晶面板上折断；同时调节第二夹持机构40，使得上裂片10与下裂片20紧贴液晶面板。
本发明通过第二夹持机构40夹持上裂片10和下裂片20的中间部分，从而使得该裂片装置在对液晶面板进行裂片时，可以调节第二夹持机构40，将上裂片10和下裂片20的中间部分紧贴液晶面板而不会弯曲，保证了上裂片10和下裂片20各个部分之间的距离的误差在0.05mm以下，从而使得裂片正常，提高了液晶面板的良率。
以上所述仅为本发明的优选实施例，并非因此限制其专利范围，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，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。
