技术领域
本发明涉及一种摩擦取向装置、组件和摩擦取向方法，以及显示基板、显示装置。
背景技术
在液晶基板制造过程中，为了使液晶分子形成一定的预倾角，需要对基板上的取向膜进行摩擦取向。
随着液晶基板的尺寸越来越大，因此在摩擦取向工艺时所使用的母板的尺寸也随之增大，但母板的利用率却随之减小。母板通常划分为多个基板，基板所在区域为母板的有效区域，用于制作成液晶基板，而相邻基板中间的区域为母板的无效区域，在对盒切割之后即被废弃。有效区域的面积占整个母板面积的比例即为母板的利用率。例如，母板尺寸为2200mm×2500mm，其在切割形成43英寸基板时的利用率为75％，切割形成46寸基板时的利用率为84.95％，。为了提高母板的利用率，可以在同一张母板上设计尺寸不同的基板，例如，在一张母板上同时设置尺寸为43寸和18.5寸的基板时，母板的利用率为90.3％。
但现有的摩擦取向装置只适用于对被划分成均匀排布的多个相同基板的母板进行摩擦，如果对同一张母板的不同基板进行摩擦，就会因不同基板间的差异对摩擦取向的均一性造成影响，从而影响液晶配向，导致画面异常。
图1和图2所示为现有的对基板进行摩擦取向的示意图。如图1或2所示，摩擦滚轮11在升降机(未示出)的作用下沿箭头方向上下和升降。由于母板上有效区域和无效区域的厚度有明显差异，因此在摩擦取向过程中，摩擦滚轮的摩擦布上就会形成与有效区域和无效区域边界相吻合的印记12。但当母板的后段的有效区域、无效区域的排 布与前段的有效区域、无效区域的排布不同、或同一母板上分布有多种尺寸的基板时(见图2)，这种带有印记的摩擦布就会在对后段的母板进行摩擦取向的过程中在有效区域留下印记，进而影响液晶面板的品质，出现画面显示不良或异常。因此，现有的摩擦取向装置在对被划分成多种不同的基板排布的母板进行摩擦时，会影响摩擦取向的均一性，进而对液晶取向的均一性产生很大影响，造成面板品质不良等。
发明内容

具体实施方式
下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
如图3所示，本发明的一个实施例提供了一种摩擦取向装置，用于对母板进行摩擦取向，包括摩擦部件1和摩擦部件控制器。摩擦部件1包括两个摩擦滚轮11，还包括对称设置在每个摩擦滚轮11两侧的升降机构32，升降机构32用于控制摩擦滚轮11上升或者下降。
需要说明的是，本实施例中所说的“上升”指远离基板，“下降”指靠近基板，在本实施例中只是针对其中一种实现方式举例说明，其他能实现远离或靠近基板的方式均包含在本发明的保护范围中，此处不再赘述，且以下实施例同样适用。
摩擦部件控制器包括第一控制器33和第二控制器34，第一控制器33与摩擦滚轮11连接，用于驱动摩擦滚轮11旋转；第二控制器34与升降机构32连接，用于驱动升降机构32上升或下降。
应能理解到的是，本文所提到的“连接”的含义包括“直接连接”和“间接连接”，例如，对象A与对象B连接，可以指的是对象A与对象B直接连接，对象A和对象B之间无其它元件，或者，对象A和对象B直接连接，即，对象A和对象B之间存在其它元件。
图4所示为图3中摩擦部件的主要结构示意图，图5所示为图4中升降机构32的局部放大图。摩擦滚轮11包括转动轴311和设置在转动轴311上的摩擦布312，第一控制器33与摩擦滚轮11的转动轴311连接，用于控制摩擦滚轮11的转动。升降机构32包括滚轮夹紧装置321、支撑梁322、连接结构323、第一楔形滑块324、第二楔形滑块325、支撑导轨326、滑块327、螺纹丝杠328和限位传感器329。滚轮夹紧装置321与摩擦滚轮11的转动轴311连接，以保证滚轮在上升和下降过程中的稳定性；支撑梁322的一端与滚轮夹紧装置321连接，另一端与连接结构323连接，用以支撑摩擦滚轮11；第一楔形滑块324分别位于连接结构323和支撑导轨326之间，第二楔形滑块325的斜面与支撑导轨326相连，另一面与螺纹丝杠328连接。同时，螺纹丝杠328还连接第二控制器34，当第二控制器34启动时，螺纹丝杠328开始旋转，从而带动滑块327在支撑导轨326上滑动，使得第一楔形滑块324和第二楔形滑块325靠近或分离，进而控制支撑梁322向上或向下运动，实现摩擦滚轮11的上升或下降。也就是说，上述的第一楔形滑块、第二楔形滑块、支撑导轨、滑块和螺纹丝杠可以构成一个传动件。限位传感器329可设置在第二楔形滑块325的斜面上， 用以限定滑块327在第二楔形滑块325的斜面上运动的边界。
本发明的另一实施例提供了一种摩擦取向组件，如图6所示。摩擦取向组件包括如本发明的上述实施例所描述的摩擦取向装置(图6中只示出摩擦滚轮)，用于运送母板的机台15和机台控制器。机台15的起始位置为坐标原点O，由此可以确定机台15在运行过程中的坐标。机台控制器与摩擦取向装置中的摩擦部件控制器通过信号线连接，用于接收机台15的坐标信息、控制机台15运行并传送信号给摩擦部件控制器，摩擦部件控制器根据机台15的坐标信息控制摩擦部件1的上升或者下降。
本发明的另一实施例提供了一种对母板进行摩擦取向的方法，如图7-图8所示，该方法可包括以下步骤：
确定机台15的起始位置，以该起始位置作为机台15的坐标原点O，根据原点O确定摩擦部件1的坐标；机台控制器控制机台15开始运行，并实时获取机台15运行过程中的坐标位置；机台控制器根据机台15的坐标信息，传递信号给控制摩擦滚轮的第二控制器，第二控制器控制摩擦滚轮实现上升或者下降；当摩擦滚轮上升或下降动作完成后，第一控制器控制摩擦滚轮转动或停止转动；此程序依次循环进行，完成对模板上的不同基板进行摩擦取向的过程。
为了方便说明摩擦滚轮的升降过程，图7和图8中将两个并排设置的摩擦滚轮分别定义为第一摩擦滚轮111和第二摩擦滚轮112。现以图6中所示的母板上不同尺寸的基板14、28为例具体说明实现摩擦取向的过程。
假设摩擦滚轮111的坐标为X。
Step 1：机台运行，当机台上排布的第一组基板B(即，基板28)到达第一摩擦滚轮111下方，即机台15的坐标为X时(机台15的坐标取值为机台上母板远离原点的一侧对应的坐标值)，第二控制器34控制第一摩擦滚轮111下降以摩擦第一组B基板，第二摩擦滚轮112位置保持不动。
Step 2：当第一摩擦滚轮111摩擦完第一组B基板的结束位置时，此时机台15的坐标为X+956(假设尺寸较大的第一组B基板的宽度为956mm)，第二控制器34控制第一摩擦滚轮111开始升起，第二摩擦滚轮112位置仍保持不变。
Step 3：当第一组A基板(即，基板14)移动到第二摩擦滚轮112下方(机台15的坐标信息依次类推)时，第二摩擦滚轮112在第二控制器34的控制下下降，开始对第一组A基板进行摩擦取向，此时第一摩擦滚轮111位置保持不变。
Step 4：在第二摩擦滚轮112摩擦第一组A基板的过程中，第二组B基板移动到第一摩擦滚轮111下方，此时第一摩擦滚轮111下降，开始摩擦第二组B基板。
Step 5：第二摩擦滚轮112摩擦完第一组A基板的结束位置时开始升起，此时第一摩擦滚轮111继续摩擦第二组B基板。
Step 6：在第一摩擦滚轮111摩擦完第二组B基板的结束位置开始升起时，第二摩擦滚轮112已经升起并保持位置不动。
Step 7：第一摩擦滚轮111上升至起始位置，并保持不动，当第二组A基板移动到第二摩擦滚轮112下方时，第二摩擦滚轮112下降并对第二组A基板进行摩擦取向直至结束。
以上7个步骤完成了对图6中所示的母板进行的一次摩擦取向，其中第一摩擦滚轮111对应B基板，第二摩擦滚轮112对应A基板。
在进一步的实施例中，在完成对母板的一次摩擦取向之后，机台控制器控制机台开始反向运行，依次反方向执行上述7个步骤，即，第二摩擦滚轮112先摩擦第二组A基板，然后第一摩擦滚轮111摩擦第二组B基板，随后第二摩擦滚轮112再完成第一组A基板的摩擦取向，第一摩擦滚轮111完成第一组B基板的摩擦取向。至此，一个母板的摩擦取向工作全部完成。通过上述过程，实现了两个摩擦滚轮单独对不同基板进行摩擦取向，从而避免不良的产生，同时机台的反向运行可以使得每个基板经过两次摩擦取向，保证了摩擦强度，进而保证产品品质。
需要说明的是，这里所说的“组”是指连续排列的相同尺寸的基板，可以为一个或多个，也可以为一排或几排，这里的所提到的“排”所在的直线垂直于基板运行方向。当然，母板上基板的排列方式并不限于本实施例中所示，替代性地，全部B基板可排列为一组，全部A基板可排列为一组，或者其他方式，只要摩擦滚轮能单独对不同尺寸的基板进行摩擦取向，它们均在本发明的保护范围之内，这里不再赘述。
利用本发明实施例提供的摩擦取向装置及摩擦取向组件对母板进行摩擦取向，可以完成对多个不同尺寸的基板的摩擦取向，避免了传统摩擦工艺中造成的取向膜不均匀而导致的显示不良。而摩擦部件的连续上升下降是在机台移动过程中进行的，机台不用停止，不仅可以避免机台停止时造成的时间浪费，还可以有效提高摩擦滚轮下降的精度。此外，利用母板上不同基板的坐标信息来控制摩擦部件的上升下降，省去了人工操作或其他采集基板形状和位置信息的组件，使得摩擦取向装置结构简单。
图9为本发明的另一实施例提供的摩擦取向装置的结构示意图。在该实施例中，摩擦取向装置中的摩擦部件可包括3个摩擦滚轮与一个中心转动轴330，摩擦滚轮绕中心转动轴330间隔设置，其与中心转动轴330通过连接轴331相连，相邻连接轴331之间的夹角β近似为120°。摩擦滚轮的结构与之前实施例所描述的摩擦滚轮的结构相似，包括转动轴311和设置在转动轴311上的摩擦布312。
该摩擦取向装置中的摩擦部件控制器包括第一控制器33和第三控制器35，第一控制器33与转动轴311连接(图9中为了图片结构清晰起见，仅示出3个摩擦滚轮中的一个连接有第一控制器33，实际上每个摩擦滚轮可连接有第一控制器33)，用于驱动摩擦滚轮旋转；第三控制器35与中心转动轴330连接，用于驱动中心转动轴330旋转，从而实现摩擦滚轮的上升或下降。
本实施例提供的摩擦取向装置中，每个摩擦滚轮可以对应一种尺寸的基板，因此本实施例提供的摩擦取向装置可以同时对母板上排布有三种尺寸基板的母板进行摩擦取向。
虽然图9所示的实施例包括3个摩擦滚轮，但是，能够领会到的是，在其它实施例中，可以包括2个或更多数目的摩擦滚轮，其结构和连接关系与本实施例相似。当摩擦滚轮个数为N时，相邻连接轴之间的夹角β为360°/N，N为正整数且分N≥2。
在包括多个这样的摩擦部件的情形中，由于每个摩擦部件包括多个摩擦滚轮，所以当其中一个摩擦部件中的摩擦滚轮或控制器出现故障或缺陷时，并不影响对其它基板的摩擦取向，并且可以较为方便地对出现故障或缺陷的摩擦滚轮进行更换。另外，除了之前讨论的让机台以正向和反向往复运行之外，还可以使得不同摩擦部件中的摩擦滚 轮相互配合，针对同一基板多次摩擦，提高对同一基板的摩擦强度，这样，可促进生产效率的提升。
基于同样的发明构思，本发明的又一实施例提供了一种摩擦取向组件，包括：
如上述实施例所述的摩擦取向装置；用于运送母板的机台；以及机台控制器。机台的起始位置可以为坐标原点，由此可以确定机台在运行过程中的坐标。机台控制器与摩擦部件控制器通过信号线连接，用于接收机台的坐标信息、控制机台运行并传送信号给摩擦部件控制器。摩擦部件控制器根据机台的坐标信息控制摩擦部件的上升或者下降。
基于如图9所示的本发明的摩擦取向装置的实施例，本发明的又一实施例提供了一种对目标进行摩擦取向的方法，其可包括如下步骤：
确定机台的起始位置，以该起始位置作为机台的坐标原点，根据原点确定摩擦部件的坐标；机台控制器控制机台开始运行，并实时获取机台运行过程中的坐标位置；机台控制器根据机台的坐标信息，传递信号给控制摩擦部件的第三控制器，第三控制器控制中心转动轴旋转，使得摩擦滚轮实现上升或者下降；当摩擦滚轮上升或下降动作完成后，第一控制器控制摩擦滚轮转动或停止转动；此程序依次循环进行，完成不同基板摩擦取向的过程。
借助图9所示的摩擦取向装置实现摩擦取向的过程与参照图7和8描述的实施例相似。所不同的是，图7和图8中并排设置的摩擦滚轮在本实施例中被替代为绕中心转动轴间隔设置的多个摩擦滚轮，之前实施例中摩擦滚轮的上升下降是通过升降机构实现的，而本实施例中摩擦滚轮的上升下降是通过中心转动轴的旋转实现的，其他过程是相似的，在此不再赘述。
利用本发明实施例提供的摩擦取向装置及组件对母板进行摩擦取向，可以完成对多个不同尺寸的基板的摩擦取向，避免传统摩擦工艺中造成的取向膜不均匀而导致的显示不良。而摩擦部件的连续上升下降是在机台移动中实现的，机台不用停止，不仅可以避免机台停止时造成的时间浪费，还可以有效提高摩擦滚轮下降的精度。包括多个摩擦滚轮的摩擦部件可以实现对多个不同基板的进行单独的摩擦取向，从而克服了现有技术中只能对单一基板进行摩擦取向的技术问题。另 外，利用母板上不同基板的坐标信息来控制摩擦部件的上升下降，省去了人工操作或其他采集基板形状和位置信息的组件，使得摩擦取向装置结构简单。
图10示意性地示出了根据本发明的又一实施例提供的摩擦取向装置，用于对基板进行摩擦取向。该摩擦取向装置包括摩擦部件和摩擦部件控制器。摩擦部件的结构和连接关系与图9所示的实施例相似，只是本实施例中的摩擦部件相比图9所示的实施例增加了升降机构32及第二控制器34，第二控制器34与升降机构32连接，用于控制升降机构上升或者下降。如图10所示，为了较为简洁的显示各部件之间的连接结构，图中仅以框图示意性地示出该摩擦取向装置的结构组成。
在一个实施例中，摩擦部件可包括3个摩擦滚轮11(图10中示意性地示出1个摩擦滚轮11)与一个中心转动轴330，摩擦滚轮11与中心转动轴330通过连接轴331相连；摩擦滚轮11绕中心转动轴330间隔设置，相邻连接轴331之间的夹角近似为120°。摩擦部件还包括升降机构32，升降机构32与中心转动轴330连接，用于控制中心转动轴330上升或者下降。
在该实施例中，摩擦部件控制器包括第一控制器33、第二控制器34和第三控制器35，第一控制器33与摩擦滚轮11连接，用于驱动摩擦滚轮11的旋转；第二控制器34与升降机构32连接，用于驱动升降机构32上升或下降；第三控制器35与中心转动轴330连接，用于驱动中心转动轴330旋转，这样，当第二控制器34控制升降机构32运动以带动中心旋转轴330升降到达预定位置后，第三控制器35可控制中心转动轴330旋转以选择将进行摩擦取向的摩擦滚轮，随后第一控制器33可控制该摩擦滚轮旋转开始作业。因此，在该实施例中，第二控制器34和第三控制器35可共同实现摩擦滚轮的上升和下降。
在该实施中，摩擦滚轮11、升降机构32的结构可以与之前的实施例所描述的摩擦滚轮和升级机构相同，此处不再赘述。本实施例中是以摩擦部件具有3个摩擦滚轮为例进行说明，实际中摩擦滚轮的个数可以根据生产需要设定，在此不做限定，即摩擦滚轮个数可以为N，相邻连接轴之间的夹角为360°/N，N为正整数且N≥2。
关于第一控制器33与摩擦滚轮的转动轴311、第二控制器34与升降机构32、以及第三控制器35与中心转动轴330之间的连接方式 在之前的实施例中也已经有所表述，升降机构32与中心转动轴330的连接方式可以和图3-6所示的实施例中升降机构32与摩擦滚轮的转动轴的连接方式相同，这里不再具体说明。
基于同样的发明构思，本发明的另一实施例还提供一种摩擦取向组件，包括：
如参照图10所描述的实施例所述的摩擦取向装置；
机台，用于运送母板；
机台控制器，机台的起始位置为坐标原点，由此可以确定机台在运行过程中的坐标。机台控制器与摩擦部件控制器通过信号线连接，用于接收机台的坐标信息、控制机台运行并传送信号给摩擦部件控制器从而控制摩擦部件的升降；摩擦部件控制器根据机台的坐标信息控制摩擦部件的上升或者下降。
基于如图10所示的本发明的摩擦取向装置的实施例，本发明的又一实施例提供了一种对母板进行摩擦取向的方法，其可包括如下步骤：
确定机台的起始位置，以该起始位置作为机台的坐标原点，根据原点确定摩擦部件的坐标；机台控制器控制机台开始运行，并实时获取机台运行过程中的坐标位置；机台控制器根据机台的坐标信息，传递信号给摩擦部件控制器的第二控制器和第三控制器中的至少一个控制器，接收到信号的控制器通过控制与其连接的结构使得摩擦滚轮实现上升或者下降；当摩擦滚轮上升或下降动作完成后，第一控制器控制摩擦滚轮转动或停止转动；此程序依次循环进行，完成不同基板摩擦取向的过程。
具体实现摩擦取向的过程可与参照图7和图8所描述的实施例的过程相似。所不同的是，图7和图8中并排设置的摩擦滚轮在本实施例中被替换为绕中心转动轴间隔设置的多个摩擦滚轮，之前实施例中摩擦滚轮的上升或下降是通过升降机构实现的，而本实施例中摩擦滚轮的上升下降则可以通过升降机构的升降或者中心转动轴的旋转两种方式中的任一种或者二者结合实现，这样的设置有利于提高摩擦滚轮上升下降的精度；另外，当其中一种控制方式出现故障时，还可以通过另一种控制方式控制摩擦滚轮的升降进行摩擦取向，延长了装置的使用寿命，便于维修和更换。本实施例中其他的结构设置和方法过程都与之前的实施例类似，在此不再赘述。
综上，利用本发明实施例提供的摩擦取向装置及***对母板进行摩擦取向，可以完成对多个不同基板的摩擦取向，避免了传统摩擦工艺中造成的取向膜不均匀而导致的显示不良，而摩擦部件的连续上升下降是在机台移动中实现的，机台不用停止，不仅可以避免机台停止时造成的时间浪费，还可以有效提高摩擦滚轮下降的精度。包括多个摩擦滚轮的摩擦部件可以实现多个不同基板的摩擦取向，从而解决了现有技术中只能对单一基板进行摩擦取向的技术问题。另外，利用母板上不同基板的坐标信息来控制摩擦部件的上升下降，省去了人工操作或其他采集基板形状和位置信息的组件，使得摩擦取向装置结构简单，降低成本，提高产品市场竞争力。
本发明的又一实施例提供了一种显示基板，该显示基板是利用本发明的上述实施例中任一实施例所述的摩擦取向装置制备得到的。
本发明的再一实施例提供一种显示装置，该显示装置包括前述实施例所述的显示基板。
