Description

框胶硬化装置及框胶硬化方法
【技术领域】
本发明实施例涉及液晶显示模组制造技术领域，尤其涉及一种用于对液晶显示模组的框胶进行硬化的框胶硬化装置及框胶硬化方法。
【背景技术】
液晶显示模组因具有低辐射性、体积轻薄短小及耗电低等特点，已广泛应用于手机、个人数字助理、笔记本电脑、个人电脑及电视等领域。
在液晶显示模组的制造过程中，通常需要对设置在薄膜晶体管（TFT）基板和彩色滤光片（CF）基板之间的框胶（seal）进行硬化。常见的框胶硬化方式是利用紫外光照射框胶，使框胶硬化后再热硬化。
在此过程中，业内的常见方法是：将紫外灯管安装在玻璃基板上方，紫外灯管发出的紫外光照射到玻璃基板及框胶。某些工艺中的液晶分子对紫外光敏感，为了防止液晶分子被照射而提前配向，还需要用光罩来遮挡照到液晶部分的紫外光，而只漏出框胶区域的紫外光。实际上，工艺中只需要紫外光照射到框胶区即可，从紫外光的光利用效率来看，紫外光的绝大部分照射在光罩或者液晶分子上，造成很大的浪费。
由于紫外灯管的价格较为昂贵，例如8.5代生产线中，每支紫外灯管的价格大约为2万元，一个框胶硬化机台所需的紫外灯管数量约为8支，因此紫外灯管成为框胶固化装置的最重要耗材。
因此，目前的框胶固化装置存在对框胶进行紫外光照射固化的光利用效率较低、生产成本较高。
【发明内容】

【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：
图1是本发明框胶硬化装置第一优选实施例的结构示意图；
图2是本发明框胶硬化装置第二优选实施例的结构示意图。
【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
第一实施例：
请参阅图1，本实施例公开了一种框胶硬化装置，所述框胶硬化装置1包括紫外光源10、导光组件12和滤光单元14。
所述紫外光源10包括一个或多个发出紫外光的紫外灯管100，其发出的紫外光波长在4-380 nm之间，以用于使框胶16硬化。
所述滤光单元14设置在所述紫外光的传播路径上，所述滤光单元14可以吸收波长小于4 nm和波长大于380 nm的光。也就是说，所述滤光单元14吸收波长大于紫外光波长和小于紫外光波长的杂光，其可以将所述紫外光源10发出的少量非紫外光吸收滤除。
所述导光组件12包括多个入光口122和多个出光口124，所述滤光单元14设置在所述紫外光源10和所述多个入光口122之间，所述紫外光源10发出的紫外光穿过所述滤光单元14后分别从所述多个入光口122进入所述导光组件12内部，并经过一次或者多次的内部反射后分别自所述多个出光口124射出，而所述多个出光口124仅对应待照射的框胶18位置。
如图1所示，在本实施例中，所述导光组件12包括多根L型导光管126，所述导光管126包括两端开口，对应的，所述多根导光管126的一端分别形成所述多个入光口122，其接收所述紫外光源10发出的紫外光。所述多根导光管126的另一端分别形成所述多个出光口124，其中，所述多个出光口124分散开来，以分别对应所述待照射的框胶18位置。所述导光管126可以为一体成型的弯折结构，也可以是由两根长直的导光管拼接而成。
所述导光管126的长度不一，可以将所述导光管126根据需要截成对应长度X1、X2、X3，也可以将所述导光管126设计为伸缩式结构，例如通过驱动马达来使得伸缩式结构的所述导光管126的长度发生变化，适应不同排布的框胶位置，从而使得所述框胶硬化装置1可以用于生产不同尺寸的液晶显示模组时，降低设备成本。
所述导光管126内包括反射表面128，所述反射表面128将自所述导光管126的一端入射的紫外光反射导向所述待照射的框胶18位置。其中，所述反射表面128可以在需要光反射处贴覆金属反射层或者涂覆光反射材料，也可以直接将反射镜放置在需要光反射处。例如，在所述导光管126的拐弯处放置一面与入射的紫外光成45°的反射镜，如此，水平入射的紫外光被所述反射镜改变传播方向，垂直向下照射框胶18。
所述多个出光口124的位置分布直接对应于待照射的框胶18的位置，如此，自所述导光组件12射出的紫外光仅照射待照射的框胶18，而不会照射到液晶区，不但提高了紫外光的利用率，也避免液晶分子被紫外光照射而提前无序配向。
对于同一片承载框胶的基板11，假设框胶区面积为a，而非框胶区面积为b，在需要相同积算光量的情况下，利用本实施例所需的紫外光量为原来的a/（a+b），可以认为紫外光源10中所需的紫外灯管100数量为原来的a/（a+b），如此可以大幅度降低设备成本。此外，由于所述紫外光源10的紫外灯管100都集中在一处，因此所述紫外灯管100的更换较为方便，不需多处操作。此外，由于所述导光管126的长度可以变化，因此可以适应不同尺寸的液晶显示模组制造，从而提高了所述框胶硬化装置1的实用性。
第二实施例：
请参阅图2，本实施例公开了一种框胶硬化装置，所述框胶硬化装置2包括紫外光源20、导光组件22和滤光单元24。
所述紫外光源20包括一个或多个发出紫外光的紫外灯管200，其发出的紫外光波长在4-380 nm之间，以用于使框胶硬化。
所述滤光单元24设置在所述紫外光的传播路径上，所述滤光单元24可以吸收波长小于4 nm和波长大于380 nm的光。也就是说，所述滤光单元24吸收波长大于紫外光波长和小于紫外光波长的杂光，其可以将所述紫外光源20发出的少量非紫外光吸收滤除。
类似于第一优选实施例，所述导光组件22包括多个入光口（图未示）和多个出光口（图未示），所述滤光单元24设置在所述紫外光源20和所述多个入光口之间，所述紫外光源20发出的紫外光穿过所述滤光单元24后分别从所述多个入光口进入所述导光组件22内部，并经过一次或者多次的内部反射后分别自所述多个出光***出，而所述多个出光口仅对应待照射的框胶（图未示）位置。
在本实施例中，所述导光组件22包括多束并联的光纤220，所述多束光纤220并联形成光纤束。所述多束光纤220的一端分别形成所述多个入光口，其接收所述紫外光源20发出的紫外光。所述多束光纤220的另一端分别形成所述多个出光口，其中，所述多个出光口分散开来，以分别对应所述待照射的框胶位置。
根据光的全反射原理，光纤220具有变换光传播方向的作用。在本实施例中，进入所述导光组件22的紫外光在所述多束光纤220内经过多次的内部全反射（total internal reflection）后，自所述多个出光***出以照射待照射的框胶。其中，所述多个出光口的位置分布直接对应于待照射的框胶的位置，如此，自所述导光组件22射出的紫外光仅照射待照射的框胶，而不会照射到液晶区，不但提高了紫外光的光利用率，也避免液晶分子被紫外光照射而提前无序配向。
同样的，对于同一片承载框胶的基板21，假设框胶区面积为a'，而非框胶区面积为b'，在需要相同积算光量的情况下，利用本实施例所需的紫外光量为原来的a'/（a'+b'），可以认为紫外光源20中所需的紫外灯管200数量为原来的a'/（a'+b'），如此可以大幅度降低设备成本。此外，由于所述紫外光源20的紫外灯管200都集中在一处，因此紫外灯管200的更换较为方便，不需多处操作。
本发明实施例还公开了一种框胶硬化方法，所述框胶硬化方法包括：
紫外光源发出紫外光；
所述紫外光经过导光组件内部反射后分别被导向多个出光口，所述多个出光口的位置仅对应待照射的框胶位置；
所述紫外光自所述多个出光口分别射出后，照射所述待照射的框胶。
进一步的，当所述待照射的框胶位置变化后，相应调整所述多个出光口的位置，以使所述多个出光口保持与所述待照射的框胶的位置对应关系。
区别于现有技术的情况，本发明实施例的框胶硬化装置及框胶硬化方法具有以下的有益效果：由于提高了紫外光源的光利用率，可以减少成本较高的紫外灯管数量，而且出光口仅对应待照射的框胶位置，避免液晶分子被紫外光照射而提前无序配向。
综上所述，本发明实施例的框胶硬化装置及框胶硬化方法具有提高光源利用率、降低制造成本和避免液晶分子提前无序配向等优点。
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它相关的技术领域，均同理包括在本发明的专利保护范围内。
