具体实施方式
为了使得从喷嘴里喷出的油墨， 能够更为均匀地喷涂于玻璃基板的涂布间隔带上， 油墨 扩散均匀， 涂布厚度均一， 本发明提供了一种喷墨涂布装置 1， 用于在设有涂布间隔带的玻 璃基板 2上喷涂油墨， 其包括基台 10和喷头 12， 所述基台 10用于放置玻璃基板 2， 所述喷 头 12包括若干个喷嘴 14， 玻璃基板 2上布置有若干个平行排列的分割柱 20， 分割柱 20之间 形成涂布间隔带 30， 其中， 所述喷嘴 14包括油墨入射口 140和油墨喷射口 142， 所述油墨由 油墨入射口 140引入， 由油墨喷射口 142向玻璃基板 2喷射出， 在涂布间隔带 30中形成不同 颜色的油墨喷涂层 40， 所述油墨喷射口 142的内径大于油墨入射口 140的内径。
其中， 玻璃基板 2上设置有若干个分割柱 20， 在分割柱 20之间形成涂布间隔带 30， 各 个涂布间隔带 30间距相等， 用于填充不同颜色的油墨。 涂布间隔带 20排列方向分别与喷嘴 14相平行， 喷嘴 14喷射出的油墨填充于涂布间隔带 20上。 一组或多组涂布间隔带 20中可 分别填充不同颜色的油墨， 所述油墨为配向膜油墨。

同时， 所述喷嘴 14呈喇叭状， 所述喷嘴 14的油墨喷射口 142比油墨入射口 140的内径 大 5-200微米， 优选 100-150微米； 所述油墨喷射口 142的外张角度为 20-89度， 优选 30-60 度。 喇叭状的喷嘴可提高所喷出的油墨量， 使得由油墨喷射口 142喷出的油墨滴的形状为椭 圆状， 扩大了油墨在水平方向上的表面积， 油墨的宽度加大， 高度变小， 使其可均匀地注入 各个涂布间隔带上， 喷涂量均匀， 各个油墨喷涂层的厚度均一。 并使得吐出的油墨在空中连 接融合形成一薄膜， 落到油墨间隔带 30中， 覆盖于玻璃基板表面， 形成油墨涂布层 40。 所 述油墨喷射口 142呈内凹形， 可有效防止油墨残留在其上。 由于无需根据涂布间隔带 30的数 量， 配置一比一喷嘴 14， 可减少喷嘴的配置数量。

所述涂布间隔带 30中放置彩色滤光片、 TFT基板或 OLED基板涂布成膜。
本发明还提供了一种喷墨涂布方法， 其包括以下步骤：
步骤 1 ) 将玻璃基板放置于基台上， 通过对位控制系统将玻璃基板与喷嘴相互对位； 步骤 2) 从喷嘴吐出油墨， 形成椭圆状油墨滴， 分散于玻璃基板上的涂布间隔带上， 形 成涂布油墨层。

本发明一种喷墨涂布装置采用了喇叭状的喷嘴， 相互紧密依靠， 相邻喷嘴之间无间隙， 既提高了油墨的喷涂量， 使得喷涂的油墨呈椭圆状， 从而更均匀地分散于各个油墨间隔带中， 形成厚度均一的油墨喷涂层， 同时， 由于喷嘴之间无间隙， 避免了残余喷墨聚集黏结于喷嘴 的外表面上， 造成喷嘴的堵塞， 减少了喷嘴清洗的工序， 保证了油墨的顺畅喷涂， 从而提高 了喷涂的效率和品质。 并且， 通过改变施加于压电传感器上的电压大小， 随之改变喷嘴的口 径， 从而调整油墨的喷射量， 因此， 可微量调整油墨喷射量， 使得喷涂工艺更为精确化。
