具体实施方式
在采用油墨针对彩膜基板进行修复时，通常将用于修复的油墨材料直接注入油墨针的针管内，通过对针管内人工施加压力将油墨挤压而出实施。如果采用玻璃材料制成油墨针，则为了储存油墨材料，针体过长极易断裂，而且操作不方便。
由于油墨挤压采用人工施压的方式，每当修复一个不良时就需要根据经验重新设定用于油墨挤压的压力值，当压力设置不准确时则需要反复设定并进行预涂，确认可以涂布的大小后，才能够在彩膜基板上完成所需要的修复过程，从而占据大量修复时间。
此外，由于对油墨挤压过程中的压力难以控制，修复过程中针管极易出现堵塞，即使每天进行点检清洗，也无法从根本上解决该问题。
为此，本公开提出一种涂覆装置，该装置能解决前述问题中的至少一者。下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1为本公开实施例所述涂覆装置的第一种管路连接结构示意图。参阅图1所示，所述涂覆装置包括固定座10，用于固定针管。其中图1中未显示固定座10上所设置针管的结构，以箭头指示针管的设置位置和针管中油墨材料的流动路径。根据图1，该实施例中，涂覆装置包括四个针管。
本公开实施例中，所述涂覆装置还包括四个第一储存罐20，用于储存不同类型的油墨材料。具体地，四个第一储存罐20可以分别储存分别对应彩膜基板上黑色矩阵层(BM)、红色(R)、绿色(G)和蓝色(B)的油墨材料，其中该些油墨材料的主要成分为有机溴化合物和各种酯类。
根据图1，本公开实施例中，每一第一储存罐20分别通过第一管路1与一个针管相连接，且不同第一储存罐20通过第一管路1连接至不同的针管。
本公开具体实施例的连接结构中，所述涂覆装置还包括气体输出装置30和第二储存罐40。具体地，该气体输出装置30可以为空气压缩机，用于输出预定压力气体；第二储存罐40用于储存清洗材料，其中该清洗材料为能够用于对第一储存罐20内的油墨材料进行清洗处理的材料，本领域技术人员应该能够了解该清洗材料的具体成分，在此不详细说明。
结合图1，本公开具体实施例中，气体输出装置30通过第一气体输出管路2延伸进入第一储存罐20的内部，其中第一气体输出管路2包括多个分支管路21，每一分支管路21分别延伸进入其中一个第一储存罐20，此外通过第二气体输出管路3延伸进入第二储存罐40的内部。具体地，本公开具体实施例中，第一气体输出管路2、分支管路21与第二气体输出管路3之间通过三通换向阈相互连接，连接至气体输出装置30的一个气体输出端，当采用气体输出装置30向其中一第一储存罐20的内部输出气体，或者向第二储存罐40的内部输出气体时，只需要使对应的三通换向阀切换至使对应管路连通的状态即可。
第二储存罐40还通过第二管路4与每一第一管路1相连接，气体输出装置30还通过第三气体输出管路5连接至第一管路1。参阅图1，本公开实施例中，每一第一管路1上分别设置有四通换向阀，连接第二储存罐40的第二管路4设置有多个三通换向阀，其中通过第一管路1上其中一四通换向阀与其中一三通换向阀的相互连接，实现第二管路4与第一管路1的连接。其中每一四通换向阀包括连通第一管路1与第二管路4的状态以及切断第一管路1与第二管路4之间连通的状态，且当第一管路1与第二管路4之间切断连通时，能够使第一管路1本身连通，使第一储存罐20内的油墨材料能够输送至针管中。当需要使第二储存罐40与其中一第一储存罐20相连通，用于对该第一储存罐20进行清洗时，可以控制对应管路上的三通换向阀和四通换向阀进行状态切换，使对应管路处于连通状态。
另外，连接气体输出装置30的第三气体输出管路5上设置有多个三通换向阀，且通过第三气体输出管路5上的其中一三通换向阀与第一管路1上的其中一四通换向阀相连接，实现第三气体输出管路5与第一管路1的连接。其中每一四通换向阀还包括连通第一管路1与第三气体输出管路5的状态以及切断第一管路1与第三气体输出管路5之间连通的状态。当需要使气体输出装置30向其中一第一管路1上输出气体，用于对相对应的第一管路1和针管执行吹干操作时，可以控制对应管路上的三通换向阀和四通换向阀进行状态切换，使对应管路处于连通状态。
采用上述图1所示的第一种管路连接结构，每一针管分别通过一个第一管路1连接至其中一个第一储存罐20，且不同针管连接至不同的第一储存罐20。当需要使用其中一种油墨材料进行彩膜基板修复时，可以控制储存对应油墨材料的第一储存罐20相连接第一管路1上的四通换向阀处于使第一管路1本身连通的状态，并使对应的分支管路连通至气体输出装置，通过相连接的第一气体输出管路2和分支管路21，气体输出装置30能够向对应的第一储存罐20的内部输出气体，使对应的第一储存罐20内的油墨材料在气体压力的作用下被挤压，通过相应的第一管路1进入针管，之后油墨材料通过针管的针头流出，用于彩膜基板修复。
由于气体输出装置30还通过第三气体输出管路5连接至第一管路1，当通过控制第一管路1上四通换向阀和第三气体输出管路5上的三通换向阀的连通状态，使对应第一管路1与第三气体输出管路5连通时，可以通过气体输出装置30向对应的第一管路1输出气体，在对应的第一管路1的针管使用过程中，可以对第一管路1和针管进行吹干操作，以防止油墨材料堵塞针头。
此外，当其中一第一储存罐20内的油墨材料使用完之后，通过控制该第一储存罐20相连接第一管路1上四通换向阀和第二管路4上三通换向阀的连通状态，使第二管路4与第一储存罐20相连通，并通过第二气体输出管路3使第二储存罐40与气体输出装置30相连通，能够向第二储存罐40的内部输出气体，使第二储存罐40内的清洗材料在气体压力的作用下被挤压，通过第二管路4和第一管路1进入第一储存罐20，用于第一储存罐20的清洗，为该第一储存罐20重新注入油墨材料作好准备。
另外，本公开实施例所述涂覆装置还提供第二种管路连接结构，如图2所示，所述涂覆装置包括固定座10，用于固定针管。本公开实施例中，涂覆装置包括四个针管。
此外，与第一种管路连接结构相同，所述涂覆装置还包括四个第一储存罐20，用于储存不同类型的油墨材料。具体地，四个第一储存罐20可以分别储存分别对应彩膜基板上黑色矩阵层(BM)、红色(R)、绿色(G)和蓝色(B)的油墨材料。
本公开实施例的连接结构中，每一针管分别通过第一管路1连接至每一第一储存罐20，且第一管路1上设置有七通换向阀，通过该七通换向阀，针管能够与其中一个第一储存罐20相连通。具体地，根据图2，每一第一储存罐20分别连接一个第一管路1，且每一第一管路1均连接至两个七通换向阀，两个七通换向阀分别与一针管相连接。该两个七通换向阀能够控制所连接的针管与其中一第一管路1相连通，以使相连通第一管路1所连接的第一储存罐20内的油墨材料能够进入针管内部，用于彩膜基板修复。
本公开实施例的连接结构中，所述涂覆装置还包括气体输出装置30和第二储存罐40。具体地，该气体输出装置30可以为空气压缩机，用于输出预定 压力气体；第二储存罐40用于储存清洗材料。
结合图2，本公开实施例的连接结构中，气体输出装置30通过第一气体输出管路2延伸进入第一储存罐20的内部，其中第一气体输出管路2包括多个分支管路21，每一分支管路21分别延伸进入其中一个第一储存罐20，此外通过第二气体输出管路3延伸进入第二储存罐40的内部。其中，第一气体输出管路2、分支管路21与第二气体输出管路3之间通过三通换向阈相互连接，并且连接至气体输出装置30的一个气体输出端，当采用气体输出装置30向其中一第一储存罐20的内部输出气体，或者向第二储存罐40的内部输出气体时，只需要使对应的三通换向阀切换至使对应管路连通的状态即可。
第二储存罐40还通过第二管路4与每一第一管路1相连接，气体输出装置30还通过第三气体输出管路5连接至第一管路1。本公开实施例的连接结构中，第二管路4和第三气体输出管路5上分别设置三通换向阀，通过三通换向阀分别连接至两个七通换向阀与每一第一管路1相连接，并能够与两个针管相连接。
根据以上，每一七通换向阀包括使其中一第一管路1与所连接的针管相连通的状态、使其中一第一管路1与第二管路4相连通的状态和使其中一第一管路1与第三气体输出管路5相连通的状态。
采用上述图2所示的第二种管路连接结构，两个针管分别能够连接至每一第一储存罐20。当需要使用其中一种油墨材料进行彩膜基板修复时，可以控制其中一针管所连接的七通换向阀切换状态，使储存对应油墨材料的第一储存罐20所连接的第一管路1与相应针管相连通，并控制储存对应油墨材料的第一储存罐20所对应的分支管路连接至气体输出装置30，通过相连接的第一气体输出管路2和分支管路21，气体输出装置30能够向对应的第一储存罐20的内部输出气体，使对应的第一储存罐20内的油墨材料在气体压力的作用下被挤压，通过相应的第一管路1进入七通换向阀所连接的针管，之后油墨材料通过针管的针头流出，用于彩膜基板修复。
由于气体输出装置30还通过第三气体输出管路5连接至每一七通换向阀，当控制彩膜基板修复过程中不同于所使用针管的另一针管所连接七通换向阀 的连接状态，使第三气体输出管路5与该另一针管所连接的管路连通，也即与该另一针管所连通时，可以通过气体输出装置30向该另一针管输出气体，从而在一个针管的使用过程中，对另一针管进行吹干操作。因此，采用第二种管路连接方式，当通过其中一针管进行彩膜基板修复时，可以对另一针管执行吹干操作，以等待另一油墨材料从针管中输出用于彩膜基板修复，能够为彩膜基板的修复工艺过程节约时间。
此外，当其中一第一储存罐20内的油墨材料使用完之后，通过控制其中一七通换向阀的连通状态，使该第一储存罐20所连接的第一管路1与第二储存罐40所连接的第二管路4相连通，并通过第二气体输出管路3使第二储存罐40与气体输出装置30相连通，能够向第二储存罐40的内部输出气体，使第二储存罐40内的清洗材料在气体压力的作用下被挤压，通过第二管路4和第一管路1进入第一储存罐20，用于第一储存罐20的清洗，为该第一储存罐20重新注入油墨材料作好准备。
当通过其中一针管采用其中一第一储存罐20的油墨材料进行彩膜基板修复时，采用上述方式，可以完成对另一第一储存罐20的清洗，具体过程可以参阅以上的描述，在此不再赘述。
相较于第一种管路连接结构，采用第二种管路连接结构，一个针管可以用于输出不同的油墨材料，且在使用其中一个针管和其中一个第一储存罐执行彩膜基板的修复过程时，能够同时完成对另一个针管的吹干操作或者对另一个第一储存罐的清洗操作。
本公开具体实施例所述涂覆装置，通过设置用于储存油墨材料的第一储存罐，与用于彩膜基板修复的针管连接，为针管提供油墨材料，能够使得针管的长度减小，避免针管过长易于折断问题。
如图3和图4，本公开具体实施例所述涂覆装置还可以包括：
固定块50，其中针管100的其中一部分设置于固定块50的内部，与固定块50一体连接；
其中固定块50设置于固定座10上，与固定座10配合连接。
所述涂覆装置中，固定块50与针管100均采用塑料材料制成。相较于玻 璃材料制成的针管，针管100采用塑料材料制成，能够避免针管易断的问题。另外，固定块50与固定座10上分别设置有可拆卸连接的配合结构，如固定块50的其中一端面上设置突起41，固定座10的与固定块50配合的端面上可以设置凹槽，将固定块50设置于固定座10上时，使固定块50上的突起41与固定座10上的凹槽配合连接。采用该种可拆卸连接方式，使得针管100使用时的安装和拆卸过程简单、方便。此外，还通过固定块50的设置，对针管100起到一定的缓冲作用。
结合图3和图4，每一针管100分别包括形成有中心管路的连接端110，而与针管100相连接的第一管路上设置有管路接口200(如图5和图6所示)，其中通过连接端110可插拔设置于管路接口200的内部，针管100与第一管路相连接。
具体地，结合图5和图6，连接端110沿圆周方向开设有卡槽111，管路接口200的内部设置有至少两个滚珠，其中连接端110插设于管路接口200的内部时，滚珠卡设于卡槽111中。
参阅图7和图8，管路接口200具体包括：
第一筒体210，内壁面上沿圆周设置有滚珠220；
设置于第一筒体210内部的第一弹簧230和与第一弹簧230固定连接的定位件240，其中定位件240上开设有中心孔，该中心孔的中心线与第一筒体210的中心位为同一直线；
其中，当连接端110插设于管路接口200的内部时，与定位件240对位连接，定位件240的中心孔与连接端110相连通。
另外，管路接口200还包括：
套设于第一筒体210外围的第二筒体250，且第二筒体250包括与第一筒体210贴合连接的第一部分和与第一筒体210相分离形成一第一安装空间251的第二部分以及形成第二安装空间252的第三部分；
第二弹簧260，套设于第一筒体210上，设置于第一筒体210与第二筒体250之间，且第二弹簧260的其中一部分设置于第一安装空间251中，另一部分设置于第二安装空间252中；
其中，第二筒体250能够相对于第一筒体210沿轴向方向移动，通过第二筒体250相对于第一筒体210沿轴向方向移动，第一筒体210的第一部分包括抵压第一筒体210上的滚珠220的第一状态，以及与滚珠220相分离的第二状态。
其中，滚珠220在第一筒体210上的安装具有能够上下移动、即沿着大致垂直于第一筒体210的中心线的方向移动的活动空间，并且滚珠220的直径大于第一筒体210的壁厚，当第二筒体250的第一部分未抵压滚珠220时，滚珠220的沿径向突出于第一筒体210的内壁面的部分较少，此时可以将第一管路1(参阅图1和图2)的连接端110顺利插设于第一筒体210的内部；当第二筒体250的第一部分抵压滚珠220时，滚珠220的沿径向突出于第一筒体210的内壁面的部分较多，此时若连接端110已插设于第一筒体210的内部，且卡槽111的位置与滚珠220的位置对应，则能够使滚珠220卡设于卡槽111中，以实现连接端110在管路接口200上的固定。
上述连接端110与管路接口200的连接方式，利用第一弹簧230的设置，为定位件240提供使其能够沿第一筒体210的中心线方向移动的轴向力，保证定位件240与连接端110的准确对位和相互抵压连接；利用第二弹簧260的设置，为第二筒体250提供使其能够沿第一筒体210的中心线方向移动的轴向力，使第二筒体250在第一状态和第二状态之间切换。
在进行连接端110相对于管路接口200的安装和拆卸时，只需要拖动第二筒体250，使第二筒体250相对于第一筒体210朝背离连接端110插入的方向移动，第二筒体250从第一状态切换至第二状态，即能够将连接端110顺利插入第一筒体210或者从第一筒体210中拔出，之后拖动第二筒体250的拖动力消失，在第二弹簧260的弹性恢复力作用下，第二筒体250恢复至第一状态，完成连接端110的插入或者拔出过程。因此，该过程能够简单、方便地得以实现。此外，连接端110与管路接口200之间的滚珠与卡槽配合的方式，能够保证连接端110与管路接口200连接后的相对旋转。
另外，根据图7和图8，定位件240上设置有密封件241，其中密封件241的外表面与第一筒体210的内壁面相抵接，以保证连接端110与定位件240之 间油墨材料传输时的密封性。
本公开具体实施例所述涂覆装置中，如图3和图9所示，所述涂覆装置还包括有针头清洗结构300，在使用时设置于固定座10使针管100的针头露出的一侧，其中针头清洗结构300上设置有针头容置槽，用于插设针管100的针头。针头容置槽的数量与针管100的数量相同，每一针头容置槽用于插设一个针管100的针头。
具体地，针头清洗结构300包括：
第一主体310，包括设置有第一开槽311的第一端面；
第二主体320，包括设置有第二开槽321的第二端面，其中第二主体320与第一主体310通过转轴连接；通过所述转轴，第二主体320能够在第一状态和第二状态之间切换；其中，在第一状态，第二端面与第一端面贴合连接，第一开槽311与第二开槽321相组合形成针头容置槽；在第二状态，第二端面与第一端面相分离。
另外，第一主体310包括第一底座和橡胶材料制成的第一内芯3101，其中第一开槽311设置于第一内芯上；第二主体320包括第二底座和橡胶材料制成的第二内芯3201，其中第二开槽321设置于第二内芯3201上。而且，橡胶材料制成的第一内芯和第二内芯分别与第一底座和第二底座可拆卸连接，以方便更换。
在针头清洗结构300使用时，可以使第一主体310相对于第二主体320呈打开状态，将从固定座10中露出的针头移动至第二主体320的第二开槽321中，之后使第一主体310相对于第二主体320盖合，这样整个针头插设于针头清洗结构300所形成的针头容置槽中。再之后，使整个固定座10相对于针头清洗结构300向远离针头清洗结构300的方向移动，通过针头相对于针头容置槽的移动，实现针头的清洁。当然，在整个针头插设于针头清洗结构300所形成的针头容置槽中之后，也可以使固定座10固定不动，使针头清洗结构300朝向以及背离固定座10移动，实现对针头的清洁。
本公开具体实施例中，所述涂覆装置还包括容置盒，设置于针头清洗结构300的下方位置，用于收容对针头清洁时掉落的材料。
本公开具体实施例所述涂覆装置，相较于利用针管储存油墨材料，本公开通过设置用于储存油墨材料的第一储存罐与针管连接，并利用气体输出装置对第一储存罐内的油墨材料施加气体压力，可以保证修复过程中压力恒定，使得施压过程自动可控，解决采用油墨针对彩膜基板进行修复时通过人工方式控制油墨挤压压力，造成修复时间较长且针头易堵塞的问题。
由于采用本公开所述涂覆装置，修复过程中压力恒定，还可以避免油墨涂布面积过大或者过小，无需每次修复之前进行预涂，可以直接进行修复操作，从而达到节约修复时间，提高修复效率的效果。
本公开实施例所述涂覆装置，通过设置用于储存清洗材料的第二储存罐，通过第二管路与第一储存罐的第一管路连接，当第一储存罐内油墨材料使用完之后，能够实现对第一储存罐的清洁；通过设置第三气体输出管路，实现气体输出装置与第一管路的连通，还能够执行对第一管路和针管的吹干操作。该些构件的设置及管路连接，能够实现对各部分的自动清洗与吹干，避免产生堵塞。
以上所述的是本公开的优选实施方式，应当指出对于本技术领域的普通人员来说，在不脱离本公开所述的原理前提下还可以作出若干改进和润饰，这些改进和润饰也在本公开的保护范围内。
