Description
一种基板涂布机的管路排泡方法、 管路排泡装置及相应的涂布机
本申请要求于 2013 年 1 月 11 日提交中国专利局、 申请号为 201310009567.0、 发明名称为 "一种基板涂布机的管路排泡方法、 装置及相 应的涂布机" 的中国专利申请的优先权, 上述专利的全部内容通过引用结合 在本申请中。 技术领域
本发明涉及薄膜晶体管液晶显示器( Thin Film Transistor Liquid Crystal Display, TFT-LCD )的制程技术, 特别涉及一种基板涂布机的管路排泡方法、 装置及相应的涂布机。
背景技术
在现有的 TFT-LCD产品的生产制程中, 一般需要对上版及下版进行处 理, 下版为 TFT P车歹l ( TFT Array )制程玻璃, 而上版则是彩色滤光片(Color Filter, CF )制程玻璃。 在这两种玻璃上均需要进行涂布的过程, 需要将光阻 涂布于两种玻璃基板上。 由于涂布机(Coater ) 的管路中或多或少会存在气 泡, 故首先需要进行排泡处理。
在现有涂布机中对管道进行排泡处理一般采用多次排泡和分段排泡的 方式来完成, 其中排泡次数通常由经验值进行确定, 但是这两种方式通常可 以将大颗气泡排出,但是微小气泡通常聚集与管路系统的接口和附着在管壁 上无法排出。 因此, 在现有的方式中, 会出现排泡不尽的情形或者需要艮多 次的排泡过程才能将气泡排尽, 在第一种情形中, 如果管道中排泡不尽通常 会导致通过喷嘴向基板最终的涂布效果不均勾, 使得产品品质发生异常, 甚 至导致产品失败, 而处理这些异常无疑会导致产能下降; 在另一种情形中, 如果需而很多次的排泡过程, 则需要进行多次的排泡过程, 每次的排泡过程 均需要光阻在管道中流动, 故会导致光阻的浪费。

可以理解的是, 需要首先预先设置第一时间与第二时间。
如图 6所示, 是本发明中进行多次排泡过程的时间周期示意图。 在一个 实施例中, 假设需要对涂布机的管道进行多次排泡操作。 在图 6中的注射泵 的启动时间周期图中,高位线段代表注射泵启动,低位线段代表注射泵关闭。 在排泡的时间周期图中, 高位线段代表排泡操作在进行中, 低位线段代理排 泡操作停止。
其中, 时间 T1代表注射泵单次启动的时间; 时间 T2代表在涂布机管路 中进行一次排泡的时间, 其开始时间与注射泵开始启动时间存在一定的时间 差; 时间 T3代表注射泵一次启动完成至涂布机管路完成一次排泡的延迟时 间, 时间 T4为两次排泡之间新增加的时间间隔 (即前述提及的第二时间), 在该新增的时间间隔中, 通过对涂布机管道进行静置, 或者向涂布机管道提 供震动波, 可以使在涂布机管道中残存的微小气泡有时间进行凝结增大体 积, 在下次进行排泡操作时, 可以增加排泡的成功率。
实施本发明实施例, 具有如下有益效果:
本发明实施例中, 通过在一次排泡完成后, 增加一个第二时间的间隔设 定, 使微小气泡在此时间间隔内可以积聚为大颗气泡, 之后再次进行排泡的 步骤, 可在相同光阻用量下提高排泡效率, 从而很好地将基板涂布机的管路 中的气泡排尽, 并能节省光阻, 提高光阻的利用效率。
以上所揭露的仅为本发明较佳实施例而已, 当然不能以此来限定本发明
之权利范围, 因此等同变化, 仍属本发明所涵盖的范围。
