Description

喷墨打印设备及制作光栅的方法 技术领域
本发明的实施例涉及一种喷墨打印设备及制作光栅的方法。 背景技术
立体显示已经成为显示技术领域的一大趋势。 而立体显示的根本原理 就是视差产生立体， 即， 使人的左眼看到左眼图像， 右眼看到右眼图像， 在人眼的视觉暂留时间之内， 给左、 右眼分别送去有视差的两幅图像，两幅 不同的图象输送到大脑后，我们所看到的就是有景深的立体图像。
视差挡板法 3D是现在最流行的一种 3D显示技术， 其基本结构包括显 示单元以及在显示单元下面的视差挡板。 视差挡板是周期性排列一条透明， 一条遮光条纹的光栅， 其中透光区域宽度一般为 20— 70微米， 而遮光区域 宽度一般为几十到几百微米。
常规技术一般采用光刻或者喷墨打印的方法制作光栅。 用光刻方法制 作光栅时， 精度较高， 但是流程很复杂、 制作效率低。 理论上可以采用喷 墨打印的方法制作光栅， 即直接在基板上打印光栅遮光条纹， 此方法工艺 筒单， 可以提高光栅的制作效率。 但是用喷墨打印的方法制作光栅时， 每 打印完一条遮光条纹后， 需要控制喷头精确移动到下一条遮光条纹的中心 然后再进行打印， 这样， 由于光栅相邻两遮光条纹的中心距离太小， 因此 必须制作出步进很小的位移控制装置才能满足光栅的制作要求， 而常规技 术中的传动设备 4艮难达到这样的精度， 而且即使有也价格非常昂贵， 这样 就导致了喷墨打印的方法 4艮难实施。 发明内容
本发明的实施例提供一种喷墨打印设备及制作光栅的方法， 使得用喷 墨打印的方法制作光栅时， 不需要制作步进很小的设备就可以满足高精度 光栅的制作， 降低了采用喷墨打印法制作光栅的设备成本， 提高了采用喷 墨打印的方法制作光栅的可行性。
根据本发明的一方面， 提供了一种喷墨打印设备， 包括：
基座； 基台， 所述基台设置于所述基座上， 用于承载待加工基板在所述基座 的表面沿第一方向直线移动； 以及
喷头组件， 所述喷头组件设置于所述基台上方， 所述喷头组件包括喷 头支架和设置于所述喷头支架面向所述基台一侧上的多个喷头， 所述多个 喷头上设有对应的喷嘴， 所述喷头组件可沿第一方向直线移动。
本发明的另一方面提供了一种制作光栅的方法， 包括： 操作所述喷头 在待加工基板上进行光栅遮光条纹的第一次打印；
操作所述基台沿所述第一方向移动第一距离， 操作所述喷头组件沿所 述第一方向移动第二距离， 操作所述喷头在所述待加工基板上沿平行于第 一次打印的光栅遮光条纹的方向进行光栅遮光条纹的第二次打印， 所述第 一距离和所述第二距离的距离差由待制作光栅遮光条纹的间距确定； 以及 重复上一步骤， 直至打印完成所有光栅遮光条纹。 附图说明
以下将结合附图对本发明的实施例进行更详细的说明， 以使本领域普 通技术人员更加清楚地理解本发明， 其中：
图 1为本发明实施例喷墨打印设备的整体结构示意图；
图 2为本发明实施例喷墨打印设备的一种喷头组件结构的示意图； 图 3为本发明实施例喷墨打印设备的基台移动组件的结构示意图； 图 4为本发明实施例喷墨打印设备的喷头移动组件的结构示意图； 图 5 为使用本发明实施例光栅制作方法制作的一个具体的光栅条纹示 意图。 具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进 行清楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分示例性 实施例， 而不是全部的实施例。 基于本发明中的示例性实施例， 本领域普 通技术人员在不需要创造性劳动前提下所获得的所有其他实施例， 都应属 于本发明保护的范围。
除非另作定义， 此处使用的技术术语或者科学术语应当为本发明所属 领域内具有一般技能的人士所理解的通常意义。 本发明专利申请说明书以 及权利要求书中使用的 "第一" 、 "第二" 以及类似的词语并不表示任何 顺序、数量或者重要性， 而只是用来区分不同的组成部分。 同样， "一个"、 "一" 或者 "该" 等类似词语也不表示数量限制， 而是表示存在至少一个。 "包括" 或者 "包含" 等类似的词语意指出现该词前面的元件或者物件涵 盖出现在该词后面列举的元件或者物件及其等同， 而不排除其他元件或者 物件。 "上" 、 "下" 等仅用于表示相对位置关系， 当被描述对象的绝对 位置改变后， 则该相对位置关系也可能相应地改变。
图 1为本发明实施例喷墨打印设备的整体结构示意图， 如图 1所示， 根据本发明的实施例的喷墨打印设备， 包括： 基座 1 , 基座 1上的设置的基 台 2, 基台 2用于承载待加工基板 7, 基台 2可在所述基座 1的表面沿第一 方向直线移动。 喷墨打印设备还包括喷头组件 3 , 所述喷头组件 3设置于所 述基台 2的上方， 所述喷头组件 3包括喷头支架 31和设置于喷头支架 31 面向基台 2—侧上的喷多个头 32, 所述多个喷头的每个上设有喷嘴 33 , 所 述喷头组件 3可沿第一方向直线移动。
本发明实施例提供的喷墨打印设备， 由于所述基台 2和所述喷头组件 3 均可沿所述第一方向移动， 因此在制作光栅时， 同时移动基台 3 和喷头组 件 2,利用基台 3和喷头组件 2移动时在第一方向上产生的距离差来保证待 制作光栅相邻两遮光条纹的间距。 由此， 使得基台 3和喷头组件 2不需要 有很高的移动精度也可完成高精度光栅的制作， 降低了采用喷墨打印法制 作光栅的设备成本， 提高了采用喷墨打印的方法制作光栅的可行性。
喷头组件 3的形式可以有多种， 例如可以为如图 1所示的形式： 所述 喷头组件 3 包括喷头支架 31和沿第一方向等间隔设置于所述喷头支架 31 面向所述基台 2—侧上的多个喷头 32, 每一个所述喷头 32面向所述基台 2 一端上均设有喷嘴 33 ,所述喷嘴 33的直径与待制作光栅遮光条纹的宽度相 等且各喷嘴 33之间的间距可调。 使用图 1所示的实施例的喷头组件 3进行 光栅打印时， 在打印不同规格的光栅时， 需要对各喷嘴 33之间的间距进行 调整，使各喷嘴 33之间的间距与待制作光栅遮光条纹的间距相适应。 由此， 只需一套喷头组件 3即可满足多种规格的光栅制作要求。喷嘴 33与喷头 32 的连接方式可以有多种， 例如可在喷头 32面向所述基台 2—端沿第一方向 开设长槽， 然后将喷嘴 33通过螺栓固定于长槽上， 每次调整时只需松开螺 栓然后将喷嘴 33在长槽上滑动即可。 但是， 由于此类可调结构在多次打印 的情况下各喷嘴 33之间的间距会出现微小的变化， 需要再次进行校正， 因 此图 1所示的实施例的喷头组件 3适用于对不同规格的光栅少量生产的情 况。
根据上面的实施例， 所属技术领域的技术人员可以容易地想出其它调 节喷嘴位置的方式的实施例。
喷头组件 3还可以设置为如图 2所示的形式： 所述喷头组件 3包括喷 头支架 31和设置于所述喷头支架 31面向所述基台 2—侧上的喷头 34, 所 述喷头 34面向所述基台 2—侧设有挡板 35 , 所述挡板 35上沿第一方向等 间隔设置有若干喷口 36,所述喷口 36的直径与待制作光栅遮光条纹的宽度 相等。 使用图 2所示的实施例的喷头组件 3进行光栅打印时， 在打印不同 规格的光栅时， 可以配备具有不同间距的喷口设计的挡板 35 , 例如通过膜 具成型方式制作具有不同喷口间距的挡板。 例如， 在挡板 35上加工出与待 制作光栅遮光条纹的间距相适应的喷口 36,使用时更换上相应的挡板 35即 可。 这种方式使更换方便且易于保证喷口 36间距的精度。 但是由于不同规 格的光栅所使用的挡板 35的规格也不相同， 因此图 2所示的实施例中的喷 头组件 3适用于对同种规格的光栅大批量生产的情况。
根据上面的实施例， 所属技术领域的技术人员可以容易地想出其它调 节喷嘴或喷口间距的实施例。
^^台 2和喷头组件 3移动的实施方式可以有多种， 只要^ ^台 2和 喷头组件 3能够在基台 2的平面方向内沿同一直线方向运动即可。 例如， 可以选用丝杠和丝杠螺母的传动方式、 传动带的传动方式或者采用直线电 机的传动方式， 其结构均为本领域技术人员能够实施的常用的机械传动结 构。 参照图 3 , 图 3所示为一个用于控制基台移动的基台移动组件 7的实施 例， 当需要 ^^台 2沿第一方向运动时， 基台 2下方设置丝杠， 丝杠 73上 配合连接有丝杠螺母 74 , 所述丝杠 73沿所述第一方向设置。 所述丝杠 73 一端通过变速箱 72与电机 71连接， 电机 71固定于基座 1上。 此结构成本 低。
图 4所示为一个用于控制喷头组件 3移动的喷头移动组件 8的实施例。 该喷头移动组件 8包括磁轨 81和推力线圏 82。 当需要使喷头组件 3沿第一 方向运动时， 只需将直线电机的磁轨 81沿第一方向设置， 然后将喷头组件 3的喷头支架 31与直线电机的推力线圏 82连接即可。 此结构传动精度高。 进一步地， 如图 1 所示， 为了提高设备的油墨储量， 节省频繁添加油 墨所耗费的时间， 提高生产效率， 优选使用油墨箱 4, 所述油墨箱 4与喷头 连接， 可向喷头持续供给油墨。
进一步地， 如图 1 所示， 为了安装被加工基板时更加精确、 方便， 本 发明的打印系统还可以包括定位装置 5。 所述定位装置 5设置于喷头支架 31上， 可对被加工基板 6和喷头支架 31的相对位置进行定位。
本发明实施例还提供了一种利用上述任一项实施例所述的喷墨打印设 备制作光栅的方法， 所述方法包括：
操作喷头在待加工基板上进行光栅遮光条纹的第一次打印；
操作所述基台 2沿第一方向移动第一距离， 操作所述喷头组件 3沿第 一方向移动第二距离， 操作所述喷头在所述待加工基板 6上沿平行于第一 次打印的光栅遮光条纹的方向进行光栅遮光条纹的第二次打印， 所述第一 距离和所述第二距离的距离差由待制作光栅遮光条纹的间距确定； 以及 重复上一步骤， 直至打印完成所有光栅遮光条纹。
本发明实施例提供的光栅制作方法， 由于所述基台 2和所述喷头组件 3 均可沿所述第一方向移动， 因此在制作光栅时， 同时移动基台 3 和喷头组 件 2,利用基台 3和喷头组件 2移动时在第一方向上产生的距离差来保证待 制作光栅遮光条纹的间距， 由此， 使得基台 3和喷头组件 2不需要有很高 的移动精度也可完成高精度光栅的制作， 降低了采用喷墨打印法制作光栅 的设备成本， 提高了采用喷墨打印的方法制作光栅的可行性。
例如， 当待制作光栅为等间距光栅且待制作光栅相邻两遮光条纹的中 心距为 W时， 打印光栅遮光条纹的方法如下：
调整所述第一距离与所述第二距离的差的绝对值 V,所述喷嘴的个数 N 以及相邻两喷嘴的中心距 B , 使其同时满足如下条件：
B和 V均为 W的正整数倍；
B和 V至少有一个为 W的奇数倍；
V < B ( N-1 ) +W;
当 B≠W时， B≠V;
操作喷头在待加工基板上进行光栅遮光条纹的第一次打印；
操作所述基台 2沿第一方向移动第一距离， 操作所述喷头组件 3沿第 一方向移动第二距离， 操作喷头在所述待加工基板上进行光栅遮光条纹的 第二次打印； 以及
重复上一步骤， 直至打印完成所有光栅遮光条纹。
采用本实施例所述的方法进行光栅打印时， 首先需要根据待打印光栅 的 W值对参 ¾ V、 B、 N进行调整， 使其同时满足上述各条件， 对上述各 条件的原理解释如下：
1 ) B为 W的正整数倍： 此条件是为了保证同一次打印中， 各喷嘴 /喷 口所打印出的光栅遮光条纹间距为 W的正整数倍。
2 ) V为 W的正整数倍： 此条件是为了保证同一喷嘴 /喷口多次打印出 的光栅遮光条纹间距为 W的正整数倍。
3 ) B和 V至少有一个为 W的奇数倍： 由于当 B为 W的偶数倍时， 相 邻两喷口打印出的光栅遮光条纹间距为 W的偶数倍， 此时若 V也为 W的 偶数倍则同一喷口各次打印出的光栅遮光条纹间距也为 W的偶数倍， 因此 最多只能打印出间距为 2W的光栅遮光条纹而无法打印出间距为 W的光栅 遮光条纹。 因此，此条件是为了保证能够打印出间隔为 W的光栅遮光条纹。
4 ) V < B ( N-1 ) +W: 此条件限制了喷嘴 /喷口的最少个数， 目的是为 了在仅通过 V值无法保证光栅遮光条纹间距的情况下可以通过多个喷嘴或 喷口的多次打印来保证光栅遮光条纹间距。
5 ) 当 B≠W时， B≠V: 若 B≠W时， B=V, 则无论打印多少次， 打 印出的相邻两光栅遮光条纹间距均不等于 W, 因此无法制作出相邻两光栅 遮光条纹间距为 W的光栅遮光条纹。
如图 5所示， 图 5为使用上述方法制作的一个光栅遮光条纹示意图， 图 5 中相同粗细的条紋表示同一次打印出的条纹， 图中由粗到细分别表示 第一次打印的光栅遮光条纹、 第二次打印的光栅遮光条纹……第五次打印 的光栅遮光条纹。 此示意图中将光栅遮光条纹设计为不同宽度只是为了区 分方便， 实际打印出的各光栅遮光条纹宽度相等。 在此实施例中， 参数 V、
N、 B与 W之间的关系如下： V=4W, B=5W, N=7。
本发明实施例提供的制作光栅的方法， 不需要制作步进很小的驱动装 置也可完成高精度光栅的制作， 降低了光栅制作设备的成本。 此方法筒单， 易于操作， 光栅制作效率高。
本发明实施例提供的喷墨打印设备及制作光栅的方法， 由于所述基台 和所述喷头组件均可沿所述第一方向移动， 因此在制作光栅时， 同时移动 基台和喷头组件， 利用基台和喷头组件移动时在第一方向上产生的距离差 来保证待制作光栅相邻两遮光条纹的间距， 由此， 使得基台和喷头组件不 需要有很高的移动精度也可完成高精度光栅的制作， 降低了采用喷墨打印 法制作光栅的设备成本， 提高了采用喷墨打印的方法制作光栅的可行性。
以上所述， 仅为本发明的示例性实施例或实施方式， 但本发明的保护 范围并不局限于此， 本技术领域的普通技术人员在本发明所公开的范围内， 可容易地想到许多变化或替换， 而这些变化和替换都应涵盖在本发明的保 护范围之内。
