Description

液晶滴下装置
技术领域
本发明涉及液晶显示器制造技术领域，特别涉及一种液晶滴下装置。
背景技术
液晶面板包括上下两片基板，中间夹着一层液晶。当光束通过这层液晶时，液晶会并排站立或扭转呈不规则状，从而阻隔或使光束顺利通过，以完成显示功能。在生产过程中，可以将液晶滴设在一片基板上，然后将滴设有液晶的基板与另一基板对盒，从而形成液晶面板。
参照图1，图1为现有技术中的液晶滴下装置的示意图。现有技术中的液晶滴下装置包括驱动器10、液晶容器20和滴头30，液晶容器20用于盛装液晶，驱动器10用于提供压力使液晶容器20中的液晶从其液晶喷头吐出，滴头30将自液晶喷头吐出的液晶滴落到基板40上，驱动器10与液晶容器20连接，滴头30与液晶喷头连通，一驱动器10对应连接一液晶容器20，一液晶容器20对应连接一滴头30。现有技术中的这种一驱动器10对应一滴头30的技术方案存在如下不足：当基板上的液晶面板的长边有a行滴液点，短边有b列滴液点时，则一共需要滴a*b次，即滴头30在需要滴液晶的坐标点之间移动a*b次，因此制造液晶显示面板所耗费的时间长，生产效率低；而且滴头30每次滴落的液晶量较大，使得滴下的液晶分布不均匀。
发明内容

附图说明
图1为现有技术中的液晶滴下装置的示意图；
图2为本发明液晶滴下装置较佳实施例的示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
参照图2，图2为本发明液晶滴下装置较佳实施例的示意图。本发明公开了一种液晶滴下装置，其包括驱动器1、液晶容器2及两滴头3，液晶容器2用于盛装液晶，其远离驱动器1的一端设有用于喷射液晶的液晶喷头，驱动器1用于提供压力使液晶容器2中的液晶从液晶容器2的液晶喷头吐出，两滴头3将自液晶喷头吐出的液晶滴落到基板4上。驱动器1与液晶容器2连接，两滴头3连接到液晶容器2的液晶喷头处。
在具体实施例中，液晶容器2设置一液晶喷头，此时两滴头3均连接至该液晶喷头，并对从该液晶喷头吐出的液晶进行分流，达到减少每个滴头3单次滴下液晶的液晶量的目的。当然在其他变形实施例中，液晶容器2可设置与滴头数量相等的液晶喷头，如对应两滴头3设置两个液晶喷头，由于驱动器1的驱动力一定，每个液晶喷头吐出液晶的液晶量相对设置一液晶喷头时的吐出液晶量减小，即达到减少每个滴头3单次滴下液晶的液晶量的目的。
本发明通过在液晶喷头处连接两滴头3，在驱动器1的作用下液晶容器2中的液晶从液晶喷头吐出，经两滴头3后滴落到基板4上，相对现有技术中一驱动器10对应一滴头30的技术方案，本发明一驱动器1对应两滴头3的技术方案具有缩短制造液晶显示面板的时间，提高生产效率的优点，并可避免因每个滴头3单次滴下液晶的液晶量大，而出现滴下的液晶分布不均匀的现象。
根据驱动器1的驱动力不同及需要每个滴头3单次滴下液晶的液晶量的大小不同，在具体实施例中，滴头3的个数不限于2个，其个数可以根据需要设置，优选地，滴头3的个数为2~4个，例如驱动器1为泵时，根据现有泵的压力增量范围，最多适合设置四个滴头3。相对现有技术中的驱动器，本发明中的驱动器1的驱动力要相对增大，驱动力的增量可根据需要设计。
在具体实施例中，本发明液晶滴下装置还包括连接管5，连接管5设置在液晶容器2的液晶喷头与两个滴头3之间，并将液晶容器2的液晶喷头与两个滴头3连通，连接管5为耐腐蚀材质制成。当液晶容器2仅设置一液晶喷头时，连接管5可以是用于对液晶喷头处的液晶进行引流，也可以是用于对液晶喷头处的液晶进行分流。当液晶容器2上设置液晶喷头的数量与滴头3的数量相等时，连接管5用于对液晶喷头处的液晶进行引流。
由于液晶本身的特性，优选地，连接管5为不透光材质制成。当然在其他变形实施例中，连接管5也可为透光材质制成，可通过在连接管5的外表面设置一层不透光层，或者可在液晶容器2的液晶喷头与两滴头3之间设置一具有不透光特性的防护件6，通过该防护件6将连接管5包裹，该防护件6还具有保护连接管5免受外力或外部环境污染的作用。较佳地，该防护件6呈圆锥形，其底面与呈圆锥形的滴头3的底面密封连接。
在一具体实施例中，连接管5包括一体成型的一总管及一端与总管连接的分管，且分管的数量与滴头3的数量相等，总管的另一端与液晶容器2的液晶喷头连接，各分管的另一端分别与滴头3连接。为了减少连接管的管壁对流经连接管中的液晶产生阻力，优选地，连接管5为直管，连接管5的数量与滴头3的数量相等。
为了保证滴头3可连续滴下液晶，在具体实施例中，滴头3为圆锥形，或者滴头3与基板4相对的一端设置成圆锥形。为了进一步减少滴头3单次滴下液晶的液晶量，优选地，滴头3中圆锥形部分的最小直径为d，d≤0.5MM。
为了进一步减少滴头3单次滴下液晶的液晶量，优选地，液晶喷头的形状为最小直径为d的圆锥形，d≤0.5MM。
在具体实施例中，本发明液晶滴下装置还包括气压阀，气压阀位于液晶容器2的液晶喷头与滴头3之间，气压阀的数量与滴头3的数量相等。通过控制气压阀打开的大小可调节滴头3单次滴下液晶的液晶量，通过控制气压阀的开闭可调整液晶分布及液晶滴落的间距。
以上所述仅为本发明的优选实施例，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。
