Description

液晶滴注装置
本发明要求2014年12月24日递交的发明名称为“液晶滴注装置”的申请号201410817854.9的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
技术领域
本发明涉及液晶滴注装置。
背景技术
薄膜晶体管液晶显示器(Thin Film Transistor Liquid Crystal Display，TFT-LCD)毋庸置疑的是现代显示器件中的主流产品。TFT-LCD一般的构成部分为，薄膜晶体管基板(TFT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TFT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。
传统的液晶注入方式已被淘汰(TFT基板与CF基板先完成对组，再利用毛细现象将液晶吸入)。现阶段，绝大部分液晶面板生产厂采用液晶滴下制程，即在对组前将计算好的液晶量滴入到CF或者TFT基板上，再将TFT基板与CF基板对组。液晶滴下制程大大的缩短了制程时间，同时节约了将近40％的液晶。
现阶段的液晶滴下管路如下：利用PUMP抽液晶，使管路及过滤器内形成负压，从而吸出液晶瓶内的液晶。由于目前液晶瓶随机台一起运动，移动过程中，液晶瓶内会产生极细小气泡，气泡会进入到过滤器的滤膜区导致以下两种不良：
1.滤膜区液面下降，滤膜利用率降低。
2.孔径为0.1um或者更大的气泡进入到0.1um的滤膜孔内造成滤膜阻塞，过滤器丧失过滤能力而报废。液晶滴下紊乱造成基板报废。
发明内容

本发明通过所述排气管的一端伸入所述过滤器内，所述排气管的另一端伸入所述液晶瓶内且位于所述液晶瓶内液晶以上的位置，通过所述排气管用于将进入所述过滤器内的气泡排出，使得过滤器内过滤部分(过滤膜)始终充满液晶，过滤器的利用率为100％，防止由于气泡进入引起的过滤器堵塞造成的异常。

具体而言，所述过滤器20内设过滤膜22，所述输液管40将所述液晶瓶10内的液晶输送至所述过滤膜22，通过所述过滤膜22的过滤后的液晶再通过输液管40输送至所述泵30，所述过滤器20内还设有容气区24，所述容气区24位于所述过滤膜22垂直上方，所述排气管50伸入所述过滤器20的位置停 留在所述容气区24内。
所述过滤器20还包括缓存区26，所述缓存区26位于所述过滤膜22的下方，经过所述过滤膜22过滤后的液晶收容在所述缓存区26内。
所述过滤器20包括壳体(未标注)和紧固件28，所述紧固件28锁附于所述壳体之正对所述容气区24的位置处，所述紧固件28设有通孔，所述排气管50穿过所述通孔以伸入所述过滤器20。所述紧固件28可以为螺母或螺柱，通孔开设在螺母或螺栓的轴心的位置。
