Description

液晶面板的制作装置及方法
技术领域
本发明涉及液晶面板制作技术领域，尤其涉及一种液晶面板的制作装置及方法。
背景技术
液晶面板包括相对设置的薄膜晶体管（TFT，Thin Film Transistor）阵列基板、彩色滤光片（CF，Color Filter）基板以及夹在两基板之间的液晶层。在进行成盒工艺时，在其中一基板上涂布框胶，在另一基板上滴注液晶，在真空状态下，利用真空贴合机对准两基板，使两基板贴合。框胶粘结TFT阵列基板和CF基板，并阻隔大气进入液晶层。
但是在两基板贴合后，液晶会扩散并与框胶接触，此时框胶未经固化，液晶与框胶接触后会逐渐将框胶溶解；并且在贴合后的液晶面板搬运至框胶固化装置的过程中，未固化的框胶暴露在大气中，空气同样会侵蚀未固化的框胶，如图1所示，其为现有技术中被液晶和空气侵蚀的框胶的示意图。液晶溶解与其接触的框胶30，形成液晶侵蚀区101；而空气则会侵蚀暴露在空气中的框胶30，形成空气侵蚀区201。如果在一定时间内没有将框胶固化，则可能出现框胶30被侵蚀而形成通孔，造成空气进入液晶中，在液晶层产生气泡，导致液晶面板的报废。
在现有技术中，框胶的固化通常采用紫外光固化和热固化两种方式。由于框胶对紫外光的反应敏感，如图2所示，图2是现有的一种液晶面板用的框胶的固化率与紫外光的积算光量之间的关系示意图，由图2可知，在积算光量为200mJ/cm2的紫外光照射下，框胶即可硬化到最终固化率的90%左右。因此，紫外光固化方式是目前常用的框胶固化方式。
但是，目前真空贴合机和紫外光固化机是分离的，TFT基板和CF基板在真空贴合机中贴合之后，经过搬动系统和/或翻转系统进入紫外光固化机进行紫外光照射。在贴合后的液晶面板从真空贴合机搬运至紫外光固化机的过程中，未固化的框胶暴露在空气中，液晶和空气同时侵蚀框胶，并且搬运的过程也需要一定的时间，会出现框胶因侵蚀而形成通孔的现象，而大气则经过通孔进入液晶中，造成液晶面板报废。

具体实施方式
以下将结合附图及实施例，对实现发明目的的技术方案作详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
如图3至图5所示，图3是本发明液晶面板的制作装置较佳实施例的俯视图；图4是将TFT基板和CF基板置于图3所示的液晶面板的制作装置中且上定盘处于待机位置时的示意图；图5是3所示的液晶面板的制作装置贴合TFT基板和CF基板后的示意图。本发明较佳实施例提出的一种液晶面板的制作装置，所述液晶面板1包括TFT基板11、CF基板12及贴合TFT基板11和CF基板12的框胶（图未示）。该液晶面板的制作装置内设有用于对液晶面板1的框胶进行预照射的紫外光源4。
本实施例液晶面板的制作装置包括相对设置的上定盘2、下定盘3及控制单元（图未示），用于贴合所述液晶面板1的TFT基板11和CF基板12。上述上定盘2可位于待机位置或贴合位置，其中，所述待机位置是指液晶面板的制作装置贴合TFT基板11和CF基板12前，上定盘2位于下定盘3上方的最高点位置，即上定盘2准备向下移动与下定盘3贴合、但未移动时所处的位置；所述贴合位置是指所述上定盘2和下定盘3将TFT基板11与CF基板12贴合时，上定盘2所处的位置。该上定盘2用于承载TFT基板11，所述下定盘3用于承载CF基板12，且该下定盘3还用于承载贴合后的TFT基板11和CF基板12。当然，在其他实施方式中，所述上定盘2也可用于承载CF基板12，相应的，所述下定盘3用于承载TFT基板11。所述控制单元用于控制上定盘2从待机位置移动至贴合位置或从贴合位置移动至待机位置。
所述液晶面板的制作装置还包括定位单元（图未示），该定位单元用于对置于上定盘2和下定盘3的基板进行定位，并使其对准。
本实施例具体将紫外光源4设置在上定盘2和下定盘3的四周，且位于下定盘3的上方。其中，紫外光源4可以为条状，还可以为其他形状；其数量沿下定盘3的四周各设置一个，也可以为两个或多个。
本实施例以沿下定盘3的四周各设置一条状紫外光源4为例进行说明。
为了使紫外光源4对TFT基板11和CF基板12之间的框胶具有较好的照射效果，优选的，上述紫外光源4设置在上定盘2的待机位置与下定盘3之间，且位于上定盘2与下定盘3的外围，即位于下定盘3的斜上方，以使紫外光源4可以从上往下对液晶面板1的框胶进行照射，使该框胶接收紫外光而预硬化。
所述紫外光源4包括紫外光灯41、光罩42及开关（图未示），所述光罩42设置在紫外光41的一侧，用于将紫外光灯41发出的光线反射至下定盘3。所述开关用于开启或关闭紫外光灯41，该开关与控制单元连接，由控制单元控制开关开启或关闭紫外光源4。
本实施例的液晶面板的制作装置通过紫外光源4对框胶进行预硬化的过程如下：
在进入所述液晶面板的制作装置前，所述TFT基板11上滴注有液晶或涂布有框胶，相应的，所述CF基板12上涂布有框胶或滴注有液晶，当然液晶和框胶可以均设置在TFT基板11上或CF基板12上。本实施例以TFT基板11上滴注液晶，CF基板12上涂布框胶为例进行说明。
搬运装置（图未示）将滴注有液晶的TFT基板11和涂布有框胶的CF基板12分别放置在上定盘2和下定盘3的预定位置，并由定位单元对TFT基板11和CF基板12进行定位，以使TFT基板11和CF基板12精确对准，此时上定盘2处于待机位置，如图4所示；然后通过所述控制单元控制所述上定盘2从待机位置向下运动至贴合位置，将TFT基板11和CF基板12贴合，在此过程中，紫外光灯41关闭，TFT基板11和CF基板12贴合后的状态如图5所示；完成贴合后，上定盘2从贴合位置向上移动至待机位置，如图6所示，在上定盘2从贴合位置向待机位置移动的过程中，通过控制单元控制开关开启紫外光灯41，紫外光灯41发出光线（如图6中箭头所示）对框胶进行预照射，使该框胶预硬化，当然也可以在上定盘2移动至待机位置后再开启紫外光灯41。
本实施例中，所述紫外光灯41发出的紫外光积算光量优选为200mJ/cm2其照度优选为为100mW/cm2，由此，在100mW/ cm2的照度下，达到200mJ/ cm2的积算光量的紫外光大约2秒即可使框胶的固化率达到90%。由于预固化时间短，预固化过程可以在搬运装置将贴合后的液晶面板1搬出所述液晶面板的制作装置之前完成，因此该预固化制程可以与搬运装置搬运贴合后的液晶面板1动作同时进行，而不会影响到液晶面板1的制作流程。
本实施例的液晶面板的制作装置通过在液晶面板1贴合后并在搬运至下一制程设备前使用紫外光对框胶进行预固化，大大增强了框胶抵抗液晶和大气侵蚀的能力，减少甚至消除后续制程中因液晶和空气侵蚀对框胶的影响，即使搬送装置中途出现故障，也不至于导致液晶面板1的报废。
如图7所示，本发明较佳实施例提出一种液晶面板的制作方法的流程示意图，本实施例采用上述实施例所述的液晶面板的制作装置来制作液晶面板，在此不做赘述。该液晶面板的制作方法包括：
步骤S101，贴合TFT基板和CF基板。
请参阅图4及图5，在所述TFT基板11上滴注有液晶或涂布有框胶（图未示），相应的，所述CF基板12上涂布有框胶或滴注有液晶（图未示），当然液晶和框胶可以均设置在TFT基板11上或CF基板12上。本实施例以TFT基板11上滴注液晶，CF基板12上涂布框胶为例进行说明。
一搬运装置将滴注有液晶的TFT基板11和涂布有框胶的CF基板12分别放置在上定盘2和下定盘3的预定位置，并由定位单元对TFT基板11和CF基板12进行定位，以使TFT基板11和CF基板12精确对准，此时上定盘2处于待机位置，如图4所示；然后通过所述控制单元控制所述上定盘2从待机位置向下运动至贴合位置，将TFT基板11和CF基板12贴合，在此过程中，紫外光灯41关闭，TFT基板11和CF基板12贴合后的状态如图5所示。
步骤S102，预固化框胶。
请参阅图6，TFT基板11和CF基板12完成贴合后，上定盘2从贴合位置向上移动至待机位置，在上定盘2从贴合位置向待机位置移动的过程中，通过控制单元控制开关开启紫外光灯41，紫外光灯41发出光线（如图6中箭头所示）对框胶进行预照射，使该框胶预硬化。当然在其他实施方式中，也可以在上定盘2移动至待机位置后再开启紫外光灯41。
本实施例中，所述紫外光灯41发出的紫外光积算光量优选为200mJ/cm2其照度优选为为100mW/cm2，由此，在100mW/ cm2的照度下，达到200mJ/ cm2的积算光量的紫外光大约2秒即可使框胶的固化率达到90%。由于预固化时间短，预固化过程可以在搬运装置将贴合后的液晶面板1搬出所述液晶面板的制作装置之前完成，因此该预固化制程可以与搬运装置搬运贴合后的液晶面板1动作同时进行，而不会影响到液晶面板1的制作流程。
本实施例液晶面板的制作方法通过在液晶面板1贴合后并在搬运至下一制程设备前使用紫外光对框胶进行预固化，大大增强了框胶抵抗液晶和大气侵蚀的能力，减少甚至消除后续制程中因液晶和空气侵蚀对框胶的影响，即使搬送装置中途出现故障，也不至于导致液晶面板1的报废。
上述经过紫外光预固化的液晶面板1，由搬送装置送至框胶紫外光固化机后，继续其紫外光固化制程，最终完成框胶达到100%的紫外光固化率。
本发明实施例液晶面板的制作装置及方法，通过在液晶面板1的TFT基板11和CF基板12贴合后并在搬运至下一制程设备前使用紫外光对框胶进行预固化，大大增强了液晶面板1的框胶抵抗液晶和大气侵蚀的能力，减少甚至消除后续制程中因液晶和空气侵蚀对框胶的影响，即使搬送装置中途出现故障，也不至于导致液晶面板1的报废。
以上所述仅为本发明的优选实施例，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。
