如图 5所示, 基板 3上一般设置有多个均匀分布的阵列基板 31 (即行向 有 n个阵列基板, 列向有 m个阵列基板), 且每一个阵列基板 31上具有块状 金属村底区域和活动区域, 且块状金属 311 的上边缘与对应的阵列基板 31 上的边缘重合。
在取向时, 将基板 3放在基台 1上, 在基板 3上涂覆取向液以形成取向 层, 将摩擦板 2分别放置在同一行阵列基板 31的活动区域内。 例如, 在传动 装置 4的传送方向是摩擦板 2的运动方向 a时,摩擦板 2上的取向摩擦布 21 的初始位置为:取向摩擦布 21的上边缘与块状金属 311的下边缘重合(即取 向摩擦布不在块状金属村底区域中),调节摩擦板 2的摩擦面与支撑面之间的 距离,进而调整取向摩擦布 21的毛发压入基板 3上取向层内的深度,传动装 置 4驱动摩擦板 2移动,进而带动取向摩擦布 21在基板 3上进行摩擦取向(沿 着基板的列向移动), 为了避免取向摩擦布 21取向到下一行上的每一个阵列 基板 31的块状金属 311所在的区域,设定取向装置的移动距离(即取向距离) 为: 每一个阵列基板 31的活动区域的长度 L与取向摩擦布 21的宽度 W之 差。
在本实施例中, 如图 6 所示, 每一个取向摩擦布 21 的宽度例如为 2cm~8cm。 也就是说, 取向布 21的宽度要小于每一个阵列基板 31的活动区 域的长度 每一个取向摩擦布 21的宽度 W例如可以为约 2cm、 4cm、 6cm、 8cm等。 在本实施例中, 每一块摩擦板 2朝向支撑面的一面贴附有多个间隔 分布的取向摩擦布 21 ,便于更好的对基板 3进行均匀取向。在其他实施例中, 每一个摩擦板上可仅具有一块取向摩擦布。
通过本实施例提供的取向装置, 有效地避免了取向摩擦布取向到阵列基 板的块状金属村底区域, 同时采用平动的方式对基板进行取向, 可以使取向 毛发的弯曲程度相同。 所以, 本实施例提供的取向装置, 提高了取向工艺的 均一性。 实施例 2
本实施例提供了如图 6所示的第二种取向装置结构示意图。 该取向装置 包括基台 1 , 至少一块摩擦板 2 (例如三个)和传动装置 4。 与实施例 1不同 的是, 本实施例的传动装置包括:
分别位于基台 1相对的两侧的支架(图中未示出);
设置于每一个支架上的输送机构 41 ,每一块摩擦板 2的一端与一个输送 机构 41固定连接, 另一端与另一个输送机构 41固定连接; 其中, 摩擦面与 基台 1的支撑面之间的间距可调。
例如, 如图 7 所示, 每一个支架包括至少两根与支撑面垂直的导向杆 51、 与导向杆 51滑动连接的托板 52、 以及驱动托板 52沿导向杆 51滑动的 驱动装置,输送机构 41设置于托板 52背离支撑面的一面。托板 52可以沿着 导向杆 51移动,进而实现摩擦板 2的摩擦面与基台 1的支撑面之间的间距可 调。 继续参考图 7, 例如, 在一个示例中, 驱动装置可以包括: 与支撑面垂直的传动丝杠 7;
固定于支撑面上且与传动丝杠 7的一端传动连接的驱动电机 6;
固定于托板 52、 与传动丝杠 7传动连接的滑块 71。
在工作时, 驱动电机 6驱动传动丝杠 7转动, 传动丝杠 7带动滑块 71 沿着传动丝杠 7上下移动, 滑块 71又带动托板 52沿着导向杆 51上下移动, 因此, 可以实现摩擦板 2的摩擦面与基台 1的支撑面之间的间距可调。
在另一个示例中, 还可以将导向杆 51 替换为由驱动电机驱动的传动丝 杠。 此时,托板的两端各固定有一个滑块,每一个滑块与传动丝杠传动连接, 以使滑块在传动丝杠上滑动。 进一步地, 为了保持托板移动的平稳性, 且始 终保持与支撑面平行, 两个传动丝杠的转动方向需要相同, 两个驱动电机的 传动速率需要相同。 工作时, 每一个驱动电机驱动对应的传动丝杠转动, 传 动丝杠带动滑块可以沿着传动丝杠上下移动, 滑块又带动托板沿着传动丝杠 上下移动, 实现摩擦板 2的摩擦面与基台 1的支撑面之间的间距可调。
本实施例的输送机构可以具有以下两种结构:
输送机构的结构一
如图 7所示, 每一个输送机构例如为传送带 411 , 摩擦板 2的两端安装 在该传送带上。 工作时, 传送带 411带动摩擦板 2移动, 进而带动取向摩擦 布 21的取向毛发摩擦基板 3 , 对基板 3内的阵列基板 31的活动区域进行取 向。 采用传送带 411传送摩擦板 2的速度比较快且均匀, 传送的比较平稳。
可选地, 为了防止传送带 411在移动过程中, 摩擦板 2从传送带 411上 脱落, 如图 7所示, 每一块摩擦板 2的两端分别与两个传送带 411通过诸如 螺釘 8的固定件连接。 更优选地, 可在螺釘 8与传送带 411的固定处设置垫 片以用于紧固。
输送机构的结构二
如图 8所示, 每一个输送机构包括:
与托板 52滑动配合的传送板 412,传送板 412朝向支撑面的一面具有滑 块 71';
与滑块 7Γ传动连接的传动丝杠 7';
固定于托板 52上的步进电机 9, 该步进电机 9的输出轴与传动丝杠 7' 的一端传动连接。
工作时,将摩擦板 2的两端安装在该传送板 412上。托板 52背离支撑面 的一面设有滑槽, 步进电机 9驱动传动丝杠 7'转动, 进而带动滑块 71'沿着传 动丝杠 7'滑动, 从而可以推动传动板 412沿着滑槽滑动。 传送板 412带动摩 擦板 2移动, 进而带动取向摩擦布 21的取向毛发摩擦基板 3 , 对基板 3内的 阵列基板 31的活动区域进行取向。
可选地, 如图 8所示, 每一块摩擦板 2的两端分别与两个传送板 412通 过诸如螺釘 8的固定件连接。 或者, 如图 9所示, 每一个传送板 412设置有 多个间隔分布的卡槽 4121 ,每一个摩擦板 2一端与一个传送板 412上的一个 卡槽 4121卡合, 另一端与另一个传送板 412上的对应位置处的卡槽 4121卡 合。 这种固定方式, 便于安装和拆卸摩擦板 2。
通过本实施例提供的取向装置, 有效地避免了取向摩擦布取向到阵列基 板的块状金属村底区域, 同时采用平动的方式对基板进行取向, 可以使取向 毛发的弯曲程度相同。 所以, 本实施例提供的取向装置, 提高了取向工艺的 均一性。
在本发明的以上实施例中, 摩擦板 2可以为一块, 也可以为多块。 也就 是说, 用在本发明实施例提供的取向装置给基板 3取向时, 可以只采用一个 摩擦板 2先对基板 3上的同一行上的阵列基板 31进行取向,然后移动基板 3 或者摩擦板 2, 对基板 3上的其它行上的阵列基板 31进行取向; 也可以采用 多个摩擦板 2, —个基板 3上的每一行阵列基板 31对应一个摩擦板 2, 这样 可以操作一次便可以对基板 3上的所有阵列基板 31进行取向,取向速度比较 快。 优选地, 若为多块时, 相邻两块摩擦板 2之间的距离相等。 下面通过具体示例说明本发明实施例提供的取向装置对基板进行取向时 的具体实现过程。
以第五代线玻璃基板 ( l.lm*1.3m )为例, 并结合图 6、 7 以输送机构 为传送带进行说明: 阵列基板按 4*3的阵列方式排布, 每个阵列基板的尺寸 为约 23cm*41cm,摩擦板 2的数量为 3块,每块摩擦板 2上的取向摩擦布 21 的个数为 4 (即每一个阵列基板对应一个取向摩擦布),每一个取向摩擦布 21 的长度约为 23.4cm, 宽度约为 4cm,传送带 411可移动的距离约为 37cm (该 距离等于 L-W ), 取向摩擦布 21的毛发长度: 约 1.2mm, 取向摩擦布 21上 的毛发压入阵列基板内的压入量约为 0.4mm。 在取向时, 将每一块摩擦板 2 放置在各行的阵列基板 21的活动区域内, 每一块摩擦板 2上的取向摩擦布 21的初始位置为:取向摩擦布 21的上边缘与块状金属 311的下边缘重合(取 向摩擦布不在块状金属村底区域中)。 工作时, 驱动电机 6驱动传动丝杠 7 转动, 进而带动滑块 71沿着传动丝杠 7上下移动, 从而带动托板 52移动来 调节摩擦板 2的摩擦面与支撑面之间的距离,使得取向摩擦布 21的毛发压入 基板 3内的值约为 0.4mm, 传送带 411移动, 进而带动取向摩擦布 21在基 板 3上进行摩擦取向(沿着基板 3的列向移动),传送带的移动距离为约 37cm 时, 停止移动, 对基板 21的取向完成。
在本发明其他实施例中, 也可以使基台 1是可以移动的, 这样便可以通 过基台 1与传动装置 4之间的相对位移对基板 3内的每一个阵列基板 31进行 取向。
上述本发明实施例提供的取向装置, 在取向时, 将基板放在基台上, 摩 擦板放置在基板行向上的活动区域内, 传动装置驱动摩擦板移动, 进而带动 取向摩擦布对基板的活动区域进行摩擦取向(沿着基板 3的列向移动),有效 地避免了取向摩擦布取向到块状金属村底区域, 同时采用平动的方式对基板 进行取向, 可以使取向毛发的弯曲程度相同。
上述本发明实施例提供的取向装置, 避免了现有取向装置中取向辊取向 到基板的块状金属村底区域, 也就避免了块状金属村底区域在灰阶状态下形 成与块状金属宽度相等的取向沟槽现象的发生。 所以, 上述本发明实施例提 供的取向装置, 提高了取向工艺的均一性。
以上所述仅是本发明的示范性实施方式, 而非用于限制本发明的保护范 围, 本发明的保护范围由所附的权利要求确定。
