Description
本揭示涉及一种辅助装置，特别是涉及一种用于液晶取样的辅助装置及具有所述辅助装置的液晶取样系统。
液晶是薄膜晶体管液晶显示器（TFT-LCD)制造业中主要的核心原料。为了保证显示器的产品质量以及优化制造工艺，液晶的品质甚为关键。对于液晶面板的生产业而言，检测液晶的成分以及液晶中污染杂质的含量是必要的。在检测上，入料时直接取样液晶原料的检验较为容易。然而，在工艺研发、生产过程、面板解析等阶段的液晶取样相对困难。
传统的液晶取样方法为，先收集目标区域的液晶至检测样品瓶中。接着，在检测样品瓶中加入溶解液晶的溶剂。最后，进行上机检测，其中检测仪器具有自动进样针与抽取泵。自动进样针可伸入检测样品瓶中的待测溶液，并且通过抽取泵将待测溶液抽出。在收集目标区域的液晶时，通常是采用陶瓷刮刀收集液晶，或者是采用玻璃刀切下部分面板，接着用溶液移取面板上的液晶。无论采用哪种方式取样，过程中均会存在带入一些固体杂质进入测试溶液的风险。由于色谱类检测设备(如液相色谱仪)的分离柱的填料粒径均在微米级别，固体杂质极易堵塞管路，进而缩短分离柱的寿命。再者，取样的溶液量不均匀也容易影响测试结果的准确性。
有鉴于此，有必要提出一种辅助装置及液晶取样系统，以解决现有技术中存在的问题。
为解决上述现有技术的问题，本揭示的目的在于提供一种辅助装置及液晶取样系统，其通过辅助装置来过滤液晶溶液中的杂质，进而可避免液晶取样系统抽出的液晶溶液含有固体杂质的问题。
为达成上述目的，本揭示提供一种用于液晶取样的辅助装置，包含：中空管，其中所述中空管的一部份浸渍在液晶溶液内，所述中空管包含：相对的第一端和第二端，且所述第一端和所述第二端皆为开口；进液段，位在所述第二端，用于让所述液晶溶液进入所述中空管；取样段，用于提供取样针抽取位在所述取样段内的所述液晶溶液；以及过滤段，位在所述进液段与所述取样段之间；过滤器，放置在所述中心管之所述过滤段且靠近所述第二端，其中所述液晶溶液从所述中空管的所述进液段进入并且通过位在所述过滤段的所述过滤器而进入到所述取样段；以及支架，用于支撑所述中空管，并使所述中空管保持在竖直状态。
本揭示其中之一优选实施例中，所述中空管的内径由所述第一端向所述第二端逐渐缩小。
本揭示其中之一优选实施例中，所述过滤器的外周缘与所述中空管的内管壁连接。
本揭示还提供一种用于液晶取样的辅助装置，包含：中空管，包含相对的第一端和第二端，且所述第一端和所述第二端皆为开口；以及过滤器，放置在所述中心管内且靠近所述第二端，其中所述中空管的一部份浸渍在液晶溶液内，且所述液晶溶液从所述中空管的所述第二端通过所述过滤器进入到所述中空管的内部。
本揭示其中之一优选实施例中，所述中空管的内径由所述第一端向所述第二端逐渐缩小。
本揭示其中之一优选实施例中，所述辅助装置还包含支架，用于支撑所述中空管，并使所述中空管保持在竖直状态。
本揭示其中之一优选实施例中，所述中空管包含：进液段，位在所述第二端，用于让所述液晶溶液进入所述中空管；过滤段，用于放置所述过滤器；以及取样段，用于提供取样针抽取位在所述取样段内的所述液晶溶液，其中所述过滤段位在所述进液段与所述取样段之间。
本揭示其中之一优选实施例中，所述过滤器的外周缘与所述中空管的内管壁连接。
本揭示还提供一种液晶取样系统，包含：容器，用于承装液晶溶液；辅助装置，设置在所述容器内，且一部份浸渍在所述液晶溶液内，用于过滤所述液晶溶液中的杂质；以及取样针，用于伸入所述容器内部并且抽取通过所述辅助装置过滤后的所述液晶溶液。
本揭示其中之一优选实施例中，所述辅助装置包含：中空管，包含相对的第一端和第二端，且所述第一端和所述第二端皆为开口；以及过滤器，放置在所述中心管内且靠近所述第二端，其中所述中空管的一部份浸渍在所述液晶溶液内，且所述液晶溶液从所述中空管的所述第二端通过所述过滤器进入到所述中空管的内部。

相较于先前技术，本揭示通过在液晶取样系统中设置可过滤液晶溶液中的杂质的辅助装置，并且在检测时，液晶取样系统会抽取过滤后的液晶溶液。藉此设计，可确保液晶取样系统抽出的液晶溶液不会含有固体杂质。
图1显示一种根据本揭示优选实施例的辅助装置的结构示意图；
图2显示将图1的辅助装置放入装有液晶溶液的容器内的示意图；以及
图3显示一种根据本揭示优选实施例的液晶取样系统的结构示意图。
为了让本揭示的上述及其他目的、特征、优点能更明显易懂，下文将特举本揭示优选实施例，并配合所附图式，作详细说明如下。
请参照图1，其显示一种根据本揭示优选实施例的辅助装置10的结构示意图。辅助装置10包含中空管11、过滤器12、和支架13。中空管11包含相对的第一端111和第二端112，且中空管11的内径由第一端111向第二端112逐渐缩小，其中第一端111和第二端112皆为开口。
如图1所示，过滤器12放置在中空管11内且靠近第二端112。过滤器12的外周缘与中空管11的内管壁连接。更明确地说，过滤器12的尺寸是介于中空管11的第一端111的截面的内径尺寸与第二端112的截面的内径尺寸之间。因此，当中空管11以竖直放置且第一端111位在相对较高的位置以及第二端112位在相对较低的位置时，放置在中空管11内的过滤器12，其外周缘会卡固在中空管11的内管壁上而不会从第二端112掉出。
如图1所示，支架13用于支撑中空管11。详言之，支架13包含固定圈和多个支脚，其中多个支脚的其中一端与固定圈连接，另一端放置在表面上(例如桌面或地面)。中空管11架设在支架13的固定圈上，使得中空管11保持在竖直状态。
请参照图2，其显示将图1的辅助装置10放入装有液晶溶液30的容器20内的示意图。辅助装置10的一部份浸渍在液晶溶液30内，用于过滤液晶溶液30中的杂质R。具体来说，当辅助装置10放入容器20内时，中空管11的第一端111靠近容器20的顶部，以及中空管11的第二端112靠近容器20的底部，并且液晶溶液30的液面高度会超过过滤器12的位置，即，过滤器12会浸泡在液晶溶液30内。再者，由于中空管11的中空结构，使得液晶溶液30可从中空管11的第二端112通过过滤器12进入到中空管11的内部。藉此设计，通过过滤器12可过滤出液晶溶液30中的固体杂质R。
优选地，由于辅助装置10会直接放入装有液晶溶液30的容器20内，为了避免辅助装置10的材料物质析出或溶解至液晶溶液30内，辅助装置10的中空管11、过滤器12、和支架13皆选用惰性材料。可选地，中空管11选用玻璃材料。再者，支架13可采用有弹性的材料与结构以让支架13具有可压缩性，藉此有利于将支架13放入容器20内。
请参照图3，其显示一种根据本揭示优选实施例的液晶取样系统1的结构示意图。液晶取样系统1包含辅助装置10、容器20、和取样针40，其中辅助装置10和容器20的相关特征与前述相同或相似，在此不加以赘述。取样针40用于伸入容器20内部并且抽取通过辅助装置10过滤后的液晶溶液30。
更明确地说，如图3所示，辅助装置10的中空管11包含进液段113、过滤段114、和取样段115。进液段113位在中空管11的第二端112，用于让液晶溶液30进入中空管11。过滤段114用于放置过滤器12。取样段115包含过滤段114至液晶溶液30的液面的范围。取样段115是用于提供取样针40抽取位在取样段115内的液晶溶液30。应当注意的是，取样针40的探针41伸入容器20内部时，探针41会从中空管11的第一端111进入到中空管11的内部，并且探针41的末端是停留在中空管11的取样段115。可以理解的是，由于过滤段114位在进液段113与取样段115之间，因此位在取样段115内的液晶溶液30是指已经通过过滤器12过滤后的液晶溶液30。藉此设计，取样针40可抽取到过滤后的液晶溶液30。
综上所述，本揭示通过在液晶取样系统中设置可过滤液晶溶液中的杂质的辅助装置，并且在检测时，液晶取样系统会抽取过滤后的液晶溶液。藉此设计，可确保液晶取样系统抽出的液晶溶液不会含有固体杂质。再者，通过将辅助装置放置在液晶取样系统中，抽出的液晶溶液直接上机检测(即放置入检测装置)，进而可避免当检测样品量少时还需先稀释和过滤等繁琐操作步骤。因此，通过采用本揭示的辅助装置可解决从面板中取出的液晶量少，以及取样后溶液中有固体杂质的问题，并且同时也可以避免在样品稀释过滤等过程中导致的目标待测物质损失的问题，以达到更高的回收率。
以上仅是本揭示的优选实施方式，应当指出，对于所属领域技术人员，在不脱离本揭示原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本揭示的保护范围。
