Description

液晶滴灌装置 技术领域
本发明涉及液晶面板生产技术，更具体地说，涉及一种液晶滴灌装置。
背景技术
在液晶面板的生产过程中，一般使用液晶滴下方式将液晶滴入有框胶围护的玻璃基板上，再将上下基板组合后形成液晶显示器件。目前使用的液晶滴下方式为采用单一液晶滴下头对单个目标进行滴注，滴下时间与滴下精度均较差。而且由于每次滴入的液晶量会存在一定的差异，容易导致同一批次的产品之间的质量存在差异，不利于大批量生产作业。
发明内容
本发明的目的在于，针对现有的灌入液晶的方式存在无法进行大批量、高精度生产的缺陷，提供一种液晶滴管装置，以解决上述问题。
本发明解决上述问题的方案是：构造一种液晶滴灌装置，包括导管容器，导管容器内设有多根液晶导管，液晶导管贯通导管容器的上端面和下端面；紧贴导管容器下端面设有挡板，挡板上对应于液晶导管的位置开设有通孔；导管容器下端面设有第一驱动件，挡板上设有第二驱动件；第一驱动件和第二驱动件驱动挡板相对于导管容器移动。

实施本发明的液晶滴灌装置，能够同时对多个液晶进行灌入液晶的操作，大幅度提升了生产效率，降低作业成本，提升产品竞争力；同时由于挡板进行位移的时候能够对所有的液晶导管的滴灌量进行相同的调整，使得所有的液晶导管的滴灌量相同，产品的质量能够保持一致。挡板通过电磁控制，能够精确控制液晶滴下量，完成液晶滴下作业，从而提高了产品的良品率。
附图说明
以下结合附图对本申请进行说明，其中：
图1为本发明较佳实施例的液晶滴灌装置的结构示意图；
图2为图1所示的液晶滴灌装置的液晶容器的结构示意图；
图3为安装了图1所示的液晶滴灌装置的生产线的结构示意图。
具体实施方式
以下结合附图和具体实施方式对本发明进行详细说明。
如图1所述为本发明液晶滴灌装置的结构示意图。本发明提供的液晶滴灌装置主要由两部分构成：相互紧贴设置的导管容器100和挡板200，挡板200紧贴在导管容器100的下端面上。在导管容器100内设有多根相同规格的液晶导管110。该等液晶导管110可以与盛装液晶的液晶容器连通，将液晶容器内的液晶导出并从管口滴下。液晶导管110均匀分布在导管容器100内，并竖直贯穿导管容器100的上端面和下端面。一般设置液晶导管110的下部为逐渐变小的结构，以控制液晶滴出时的形状。考虑到实际产品的规格，一般液晶导管110的下部开口直径为0.1mm～4mm。
在挡板200上，对应于各个液晶导管110的位置开设有通孔210。较佳的，通孔210的形状与大小设置成与液晶导管110下部开口相匹配。当控制挡板200的各个通孔210对准液晶导管110的时候，液晶能够通过液晶导管110滴出；而当挡板200与液晶导管110相互错位的时候，液晶导管110被挡板200的其他位置所挡住，液晶无法滴出。通过控制挡板200在限定的时间内切换位置，就能够精确控制液晶滴出的量。
为了实现对挡板200的精确控制，在导管容器100上嵌入第一电磁线圈120作为第一驱动件，在挡板200上嵌入第二电磁线圈220作为第二驱动件，两个线圈的绕设方向相同，绕设的线圈数也相同。当通入两个线圈的电流使两个线圈分别产生正负磁场的时候挡板200的通孔与液晶导管110的开口相重叠，反之，挡板200的通孔与液晶导管110的开口错位。通过改变通入线圈的电信号，可以改变挡板200的位置。并且在挡板200的移动频率与电信号的切换频率相一致。当移动频率加快时可以得到小滴的液晶滴下量，反之，当移动频率变慢时，可以得到大滴的液晶滴下量，从而精确控制滴下液滴的大小。在实际使用的时候，一般使两个线圈中的一个通入固定不变的电信号，以产生固定的磁场，然后改变另一电磁线圈通入的电信号，以实现改变挡板200的相对位置。
在本实施例中，采用电磁线圈作为驱动件进行对挡板200的驱动，还可以采用其他的方式，例如在导管容器100上装配磁铁，在挡板200上设置电磁线圈，也能实现对挡板200的驱动效果，即第一驱动件为磁铁或电磁铁，第二驱动件为电磁线圈。
考虑到挡板200的形状，通常将第二电磁线圈220沿着挡板200的边缘进行绕设，以降低电磁线圈的设置难度。在设置挡板200的时候，还要考虑挡板200与导管容器100之间的摩擦所带来的精度影响，因此，可以选用产生摩擦力较小的陶瓷材料制作挡板200。
为了进一步精确控制液晶滴出的量，在导管容器100的上部加设如图2所示的液晶容器300。液晶容器300内部为一个用于容纳液晶的空腔，在该空腔的底部开设有与液晶导管110连通的开口330，空腔内的液晶能够通过该开口330流到液晶导管110内。在液晶容器300的顶部开设有用于灌入液晶的液晶注入口320，用于滴灌的液晶能够通过该液晶注入口320进行补充。在液晶容器300的顶部还开设有一个用于通入加压气体的气体通入口310，一般的，通入的加压气体为氮气。将氮气通入气体通入口310，能够对液晶容器300内的压力进行调整，从而改变液晶的滴出速度以及液滴的大小。
较佳的，液晶容器300采用如图2所示的上表面大于下表面的倒台形结构，采用这样的结构，液晶容器30内的液晶较容易从开口330流出。
当本发明配合生产线工作的时候，其结构如图3所示。导管容器100由支撑架500支撑，设置在生产流水线的正上方。当待滴灌液晶的玻璃基板400移动到合适位置后，支撑架500带动导管容器100下降至适当的高度，并进一步的微调导管容器100的位置，当液晶导管110的对准玻璃基板400的各个液晶填充位410后开始填充液晶。
填充时，向第一电磁线圈120和第二电磁线圈220分别通入用于控制的电信号，使得挡板200相对于导管容器100在水平方向上移动。当需要滴灌较大的液滴时，挡板200以较低的频率往复移动，当需要滴灌较小的液滴时，挡板200以较高的频率往复移动。此外，还可以通过控制通入的氮气来控制液滴的大小：当需要滴灌较大的液滴时，通入较多的氮气，使得液晶容器内的气压升高；反之，则降低液晶容器内的气压。
完成一块玻璃基板的滴灌之后，生产线带动下一块玻璃基板移动到对应位置，再次进行滴灌。完成所有的液晶滴下作业后，可以将各个部件拆下，清洗备用。
以上仅为本发明具体实施方式，不能以此来限定本发明的范围，本技术领域内的一般技术人员根据本创作所作的均等变化，以及本领域内技术人员熟知的改变，都应仍属本发明涵盖的范围。
