Description

液晶基板框胶涂覆装置及液晶基板框胶涂覆方法
【技术领域】
本发明涉及一种液晶基板框胶涂覆装置，特别涉及一种涂覆效率比较高的液晶基板框胶涂覆装置，本发明还涉及一种应用上述液晶基板框胶涂覆装置的液晶基板框胶涂覆方法。
【背景技术】
薄膜晶体管液晶显示器（Thin Film Transistor Liquid Crystal Display，TFT-LCD）已经成为了现代IT、视讯产品中重要的显示平台。TFT-LCD一般包括上下相对设置的薄膜晶体管基板（Array基板）、彩色滤光片基板（CF基板）和夹设在Array基板与CF基板之间的液晶材料。TFT-LCD的主要工作原理为：通过适当的电压加载在Array基板与CF基板之间的液晶材料，使液晶分子在电压作用下发生偏转，通过不同电压控制得到不同的穿透率，从而实现了显示。
现阶段，Array基板与CF基板的结合主要通过框胶（sealant）的粘贴完成，CF基板端的电信号主要通过半径为微米级的镀金高分子小球（Au-Ball）进行连接Array基板端的线路。
在液晶显示面板制作工艺中，通常是从一块尺寸较大的母基板中切割出多块基板。在此过程中，需要将Array基板与CF基板通过框胶进行贴合。目前，需要在Array基板或CF基板涂覆主框胶、副框胶和导电介质。其中，主框胶的主要作用是进行Array基板与CF基板贴合，其位置位于显示区外；辅框胶主要在Array基板与CF基板贴合时起到保护作用，在母基板切割时会去掉；导电介质涂覆在主框的路线上，且其一般在主框胶和副框胶涂覆过程中或涂覆完成后进行涂覆。
现阶段框胶与导电介质的涂覆方式主要有两种：第一种，为先进行主框胶涂覆以及辅框胶涂覆，最后进行导电介质涂覆；第二种，将主框胶与导电介质混合，然后在一道工序中完成主框胶与导电介质的涂覆，然后进行副框胶涂覆。
上述两种涂覆方式存在的主要问题是：首先，无论是第一种涂覆方式还是第二涂覆方式，前后需要至少两道涂覆工序，耗时较长；其次，在第二种涂覆方式中，由于导电介质全部混合在主框胶中，使得导电介质的消耗量明显增加从而导致材料成本上升，同时由于导电介质涂覆在不必要的信号线部位增加了产品缺陷的风险，降低了产品的品质。
【发明内容】
为了克服现有技术中液晶基板框胶涂覆的工艺耗时较长、材料成本较高的问题，本发明提供一种液晶基板框胶涂覆装置及液晶基板框胶涂覆方法，能够使框胶涂覆均匀、节省工艺时间和节省材料成本的优点。
本发明解决技术问题所采用的技术方案是：提供一种液晶基板框胶涂覆装置，包括：第一框胶喷嘴、第二框胶喷嘴、导电介质喷嘴和调节轴；第一框胶喷嘴和导电介质喷嘴相对间隔固定，第二框胶喷嘴与第一框胶喷嘴和导电介质喷嘴相对间隔固定，调节轴调节第一框胶喷嘴和第二框胶喷嘴之间的距离；第一框胶喷嘴、第二框胶喷嘴和导电介质喷嘴一并移动，且第一框胶喷嘴和第二框胶喷嘴一并打开或关闭，第一框胶喷嘴沿第一预设路线对液晶基板中的一液晶显示面板显示区外的粘合区域进行第一框胶涂覆，第二框胶喷嘴一并沿第二预设路线对液晶显示面板的显示区外区域的切割区域进行第二框胶涂覆。

【具体实施方式】
下面对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
请参阅图1与图2，图1是本发明液晶基板框胶涂覆装置一较佳实施例的平面结构在倾斜视角下的(例如：135度)示意图，图2是图1所示液晶基板框胶涂覆装置的一种喷嘴排列方式正视示意图，本发明液晶基板框胶涂覆装置的具体实施例如下：
一种液晶基板框胶涂覆装置1，用于对液晶基板进行框胶涂覆，其中所述液晶基板用来制成一个液晶显示面板，或用来切割制成两个或多个液晶显示面板。所述液晶基板框胶涂覆装置1包括第一框胶喷嘴10、第二框胶喷嘴11和导电介质喷嘴12。
其中，所述第一框胶喷嘴10和导电介质喷嘴12相对间隔固定，所述第一框胶喷嘴10与所述导电介质喷嘴12一并沿第一预设路线移动过程中，在所述导电介质喷嘴12移动到第一预设路线中的预设位点时，打开导电介质喷嘴12对液晶基板进行导电介质18涂覆，并在导电介质18涂覆完成所述预设位点后关闭所述导电介质喷嘴12。
所述第二框胶喷嘴11与所述第一框胶喷嘴10和导电介质喷嘴12相对间隔固定，在所述第一框胶喷嘴10对所述液晶基板中的一液晶显示面板显示区外的粘合区域进行第一框胶涂覆时，所述第二框胶喷嘴11沿第二预设路线对所述液晶显示面板的显示区外的切割区域进行第二框胶涂覆。
所述第一框胶喷嘴10与所述导电介质喷嘴12的连线垂直于所述第一框胶喷嘴10和所述第二框胶喷嘴11的连线，其排列方式如图2所示。所述第一框胶喷嘴10与所述导电介质喷嘴12的连线也可以倾斜于所述第一框胶喷嘴10和所述第二框胶喷嘴11的连线，其排列方式如图3所示，其中，图3是图1所示液晶基板框胶涂覆装置的喷嘴另一种排列方式正视示意图，图3中所示的所述第一框胶喷嘴10和所述第二框胶喷嘴11与框胶容器的出胶口（见下文）来源的距离相等。
所述液晶基板框胶涂覆装置1还包括调节轴13、框胶容器14、第一框胶喷嘴控制阀100、第二框胶喷嘴控制阀110、导电介质喷嘴控制阀120、导电介质容器15和对位标记识别单元16。
其中，所述调节轴13分别连接所述第一框胶喷嘴10和所述第二框胶喷嘴11，其主要作用是调节所述第一框胶喷嘴10和所述第二框胶喷嘴11之间的距离，从而满足不同产品工艺的需要。例如，所述调节轴13可以为一可伸缩的长轴，所述第一框胶喷嘴10和所述第二框胶喷嘴11分别设置在所述调节轴13的两端，当需要调节所述第一框胶喷嘴10和所述第二框胶喷嘴11之间的距离时，可以调整缩进或拉长所述调节轴13本身的长度。又例如，所述调节轴13可以包括滑槽和固定块，所述第一框胶喷嘴10和所述第二框胶喷嘴11可以在所述滑槽内滑动，并可以通过所述固定块来固定其在所述滑槽中的位置。
所述框胶容器14的主要作用是盛装框胶17，并提供给所述第一框胶喷嘴10和所述第二框胶喷嘴11。所述框胶容器14包括一出胶口（未标示），所述出胶口一起连接所述第一框胶喷嘴10和所述第二框胶喷嘴11，且所述出胶口位于距离所述第一框胶喷嘴10和所述第二框胶喷嘴11相等的中间位置。也就是说，框胶容器14中盛有框胶17时，所述第一框胶喷嘴10处和所述第二框胶喷嘴11处的压强是相同的。所述框胶17在涂覆后形成主框胶和副框胶，其中所述主框胶位于液晶显示面板的显示区外部，所述副框胶位于所述主框胶的外围。
所述第一框胶喷嘴控制阀100设置在所述第一框胶喷嘴10的喷出口和所述框胶容器14的出胶口之间，其主要作用是控制所述第一框胶喷嘴10与所述框胶容器14之间的连通与关闭。例如，当所述第一框胶喷嘴10需要喷涂框胶17时，可以控制所述第一框胶喷嘴控制阀100处于打开状态；当所述第一框胶喷嘴10不需要喷涂框胶17时，可以控制所述第一框胶喷嘴控制阀100处于关闭状态。类似的，所述第二框胶喷嘴控制阀110设置在所述第二框胶喷嘴11的喷出口和所述框胶容器14的出胶口之间，其主要作用是控制所述第二框胶喷嘴11与所述框胶容器14之间的连通与关闭。例如，当所述第二框胶喷嘴11需要喷涂框胶17时，可以控制所述第二框胶喷嘴控制阀110处于打开状态；当所述第二框胶喷嘴11不需要喷涂框胶17时，可以控制所述第二框胶喷嘴控制阀110处于关闭状态。所述第一框胶喷嘴控制阀100和所述第二框胶喷嘴控制阀110可以是机械式控制阀，也可以是电子开关式控制阀。
所述导电介质容器15的主要作用类似于所述框胶容器14，所述导电介质容器15主要用来盛装导电介质18，并提供给所述导电介质喷嘴12。所述导电介质容器15包括一出口（未标示），所述出口与所述导电介质喷嘴12相通。其中，所述导电介质容器15中盛装的导电介质18包括多个半径为微米级的镀金高分子小球。
所述导电介质喷嘴控制阀120设置在所述导电介质喷嘴12的喷出口和所述导电介质容器15的出口之间，其主要作用是控制所述导电介质喷嘴12与所述导电介质容器15之间的连通与关闭。例如，当所述导电介质喷嘴12需要喷涂导电介质18时，可以控制所述导电介质喷嘴控制阀120处于打开状态；当所述导电介质喷嘴12不需要喷涂导电介质18时，可以控制所述导电介质喷嘴控制阀120处于关闭状态。
所述对位标记识别单元16的主要作用是识别液晶基板上的对位标记。为了在贴合和切割时准确对位，液晶基板上通常会设置对位标记，例如在液晶基板的四个角落分别设置一十字形对位标记。所述对位标记识别单元16可以为一CCD摄像头，其与一控制装置（图未示）连接。
请参阅图4，图4是本发明液晶基板框胶涂覆方法一较佳实施例的步骤示意图。所述液晶基板框胶涂覆方法利用本发明实施例的液晶基板框胶涂覆装置1对液晶基板进行框胶涂覆，其包括：将第一框胶喷嘴10、第二框胶喷嘴11和导电介质喷嘴12一并移动，一并打开或关闭所述第一框胶喷嘴10和所述第二框胶喷嘴11，将第一框胶喷嘴10沿第一预设路线对所述液晶基板进行第一框胶涂覆，在所述第一框胶喷嘴10沿第一预设路线移动过程中，将所述导电介质喷嘴12移动到第一预设路线中的预设位点时，打开所述导电介质喷嘴12对液晶基板进行导电介质18涂覆，并在导电介质18涂覆完成所述预设位点后关闭所述导电介质喷嘴12。
其中，所述将第一框胶喷嘴10沿第一预设路线对所述液晶基板进行第一框胶涂覆步骤包括：将第一框胶喷嘴10沿第一预设路线对所述液晶基板中的一液晶显示面板显示区外区域进行第一框胶涂覆，并且将第二框胶喷嘴11沿第二预设路线对所述液晶显示面板的显示区外区域进行第二框胶涂覆。根据工艺的不同需求，在所述第一框胶喷嘴10进行第一框胶涂覆时，所述第二框胶喷嘴11可以同时沿第二预设路线对所述液晶显示面板的显示区外区域进行第二框胶涂覆，所述第二框胶喷嘴11也可以在所述第一框胶喷嘴10进行第一框胶涂覆之前或者之后沿第二预设路线对所述液晶显示面板的显示区外区域进行第二框胶涂覆，所述第二框胶喷嘴11也可以在所述第一框胶喷嘴10进行第一框胶涂覆的部分时间内沿第二预设路线对所述液晶显示面板的显示区外区域进行第二框胶涂覆。
当然，在将所述第一框胶喷嘴10沿第一预设路线对所述液晶基板进行第一框胶涂覆、将第二框胶喷嘴11沿第二预设路线对所述液晶基板进行第一框胶涂覆步骤之前，还包括：确认所述液晶显示面板在液晶基板中的对位标记；以及根据所述对位标记将所述第一框胶喷嘴10移动至第一预设位置（同时作为导电介质18涂覆的预设位点，见下文）和将所述第二框胶喷嘴11移动至第二预设位置（同时作为导电介质18涂覆的预设位点，见下文）。
请参阅图5，图5是本发明液晶基板框胶涂覆方法对液晶基板涂覆框胶的示意图。以下结合图1举例说明所述液晶基板框胶涂覆方法如何利用本发明实施例的液晶基板框胶涂覆装置1对液晶基板进行框胶17涂覆。图5中，液晶基板2的左上角设有对位标记20，所述对位标记20可以通过所述对位标记识别单元16进行辨识，从而确认框胶17涂覆的起点。其中，所述第一框胶喷嘴10沿着第一预设路线涂覆框胶17形成位于内侧的主框胶21（即第一框胶），所述第二框胶喷嘴11沿着第二预设路线涂覆框胶17形成副框胶22（即第二框胶），假设涂覆的顺序为图5所示的A→B→C→D→A。
首先，通过所述对位标记识别单元16确认所述对位标记20的位置后，移动所述第一框胶喷嘴10和所述第二框胶喷嘴11到A点位置准备进行框胶17涂覆。初始状态下，所述第一框胶喷嘴控制阀100、所述第二框胶喷嘴控制阀110和所述导电介质喷嘴控制阀120都处于关闭状态。在从A点到B点位置过程中，所述第一框胶喷嘴控制阀100和所述第二框胶喷嘴控制阀110分别打开，从而所述第一框胶喷嘴10进行主框胶21涂覆，所述第二框胶喷嘴11进行副框胶22涂覆。在移动至A点和B点之间的A’B’位置时，所述导电介质喷嘴控制阀120打开，在适当压力的作用下，导电介质滴落涂覆在A点，当A点的导电介质18涂覆完成后，所述导电介质喷嘴控制阀120关闭。
除了A点之外，所述第一预设路线上还包括多个其它预设位点。类似的，在完成上述从A点至B点的涂覆后，所述第一框胶喷嘴10和所述第二框胶喷嘴11继续移动，所述导电介质喷嘴12一并跟随所述第一框胶喷嘴10移动，当所述导电介质喷嘴12分别移动至所述多个其它预设位点（例如B点、C点和B点与C点之间）时，将所述导电介质喷嘴12对所述液晶基板2进行导电介质18涂覆，并在预设位点涂覆完成导电介质18涂覆后关闭所述导电介质喷嘴12。
相较于现有技术，本发明液晶基板框胶涂覆装置和液晶基板框胶涂覆方法一并进行主框胶和副框胶的涂覆，并且在主框胶涂覆过程中，将导电介质喷嘴移动到需要涂覆的预设位点时，才打开导电介质喷嘴对液晶基板进行导电介质涂覆，并在导电介质涂覆完成预设位点后关闭所述导电介质喷嘴。也就是说，在一个涂覆周期内即完成了主框胶、副框胶和导电介质的涂覆，避免了分为多个涂覆周期完成带来的耗时较长问题，明显提高了涂覆效率。此外，由于导电介质和框胶是分开盛装，导电介质只在需要使用到的位置才进行涂覆，所以可以精确控制导电介质的用量，明显降低了材料成本。在大尺寸液晶显示面板，例如第八代液晶生产线上生产47英寸液晶显示面板时，本发明液晶基板框胶涂覆装置和液晶基板框胶涂覆方法的优点尤为突出，可以大幅度节省工时和材料。
综上所述，本发明液晶基板框胶涂覆装置和液晶基板框胶涂覆方法具有工艺耗时较短、材料成本较低的优点。
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。
