Description

基板清洗装置 技术领域
本发明的实施例涉及一种基板清洗装置。 背景技术
清洗是平板显示器所用基板的生产过程中非常重要的一个环节, 无论是 在基板 I¾ 之前, 还是在基板生产工艺完成之后, 清洗效果的好坏都会直接 影响基板的产品质量。
现有的基板清洗装置大多采用固定的喷淋管道, 喷淋管道上具有朝向基 板的喷嘴, 在对基板进行清洁时, 喷嘴将喷淋管道内的液体沿垂直于基板的 方向喷向基板表面, 来实现对基板被清洁面的清洗。 但是这种清洗方式, 能 够直接喷进基板表面的沟道、 凹槽或窄缝内的液体较少, 对基板的沟道、 凹 槽或窄缝内残留杂质的清洁效果较差, 从而影响了基板整体的清洁效果。 发明内容
本发明的实施例提供了一种基板清洗装置, 其能够在对基板移动速度影 响较小的前提下, 提高对基板表面的清洁效果。
本发明的一个方面提供了一种基板清洗装置, 包括: 内部具有清洗室的 壳体; 枢装于所述壳体、 且沿基板移动方向并排分布的多个喷淋管道, 每一 液口, 每一个所述喷淋管道的一端具有与其同轴固定的传动齿轮; 与所述传 动此轮连接以通过所述传动齿轮驱动所述喷淋管道同频率往复转动的驱动系 统, 其中一部分所述喷淋管道的往复转动方向与另一部分所述喷淋管道的往 复转动方向相反。
采用本发明实施例提供的基板清洗装置对基板被清洁面进行清洗时, 通 过外部的输送管道将液体持续注入到喷淋管道内, 喷淋管道内的液体通过喷 液口喷向基板表面。 由于各喷淋管道同频率轴向往复转动, 而喷淋管道的轴 向往复转动会带动喷液口持续喷出的液体往复摆动, 使得液体从喷液口喷出 的方向与基板之间的角度发生规律性变化, 从而保证了有更多的液体能够直 接喷进基板表面的沟道、 凹槽或窄缝内, 提高对基板表面的沟道、 凹槽或窄 缝内残留杂质的清洗效果。
另外, 由于两部分喷淋管道往复转动方向相反, 使得两部分喷淋管道上 喷液口持续喷出的液体的往复摆动方向相反, 从而使得转动方向相反的两部 分喷淋管道上的液体从喷液口喷出的方向相反, 喷出方向相反的液体对基板 移动时的推动效果和阻碍效果相互抵消, 减小了液体的沖击对基板在运输设 备上运行速度的影响。 因此, 本发明提供的基板清洗装置能够在对基板移动 速度影响较小的前提下, 提高对基板表面的清洁效果。 附图说明

驱动系统 4开启后, 驱动系统 4驱动一部分传动齿轮 3按照先逆时针、 后顺时针的方式轴向往复转动, 并带动与该部分传动齿轮 3中的每一个传动 齿轮 3同轴固定的喷淋管道 2也按照先逆时针、 后顺时针的方式轴向往复转 动; 同时, 驱动系统 4还驱动另一部分传动齿轮 3按照先顺时针、 后逆时针 的方式轴向往复转动, 带动另一部分喷淋管道 2按照先顺时针、 后逆时针的 方式轴向往复转动。 这两部分传动齿轮 3轴向往复转动的频率均相同。
采用本实施例提供的基板清洗装置对基板 1表面进行清洗时, 喷淋管道 2 与外部的输送管道(未示出 )连通, 外部的输送管道将清洗液体持续注入 到喷淋管道 2内。喷淋管道 2内的液体通过喷液口 21喷向下方放置的基板 1 表面。各喷淋管道 2同频率轴向往复转动的同时带动从喷液口 21持续喷出的 液体往复摆动,使得液体从喷液口 21的喷出方向与基板 1之间的角度发生规 律性变化, 从而保证了更多的液体能够直接喷进基板 1表面的沟道、 凹槽或 窄缝内, 提高对基板 1表面的沟道、 凹槽或窄缝内残留杂质的清洗效果。
另外, 由于两部分喷淋管道 2往复转动方向相反, 使得两部分喷淋管道 2上喷液口 21持续喷出的液体的往复摆动方向相反,从而使得转动方向相反 的两部分喷淋管道 2上的液体从喷液口 21喷出的方向相反,喷出方向相反的 液体对基板 1的推动效果和阻碍效果相互抵消, 减小了液体的沖击对基板 1 在运输设备上运行速度的影响。
因此, 本实施例提供的基板清洗装置能够在对基板移动速度影响较小的 前提下, 提高对基板表面的清洁效果。
例如, 往复转动方向相反的两部分喷淋管道 2的数量相同; 例如, 两部 分喷淋管道 2的喷液口 21的数量相同, 彼此相对或彼此错开布置。
这样,在任一时刻, 两部分喷淋管道 2上的喷液口 21喷出的液体作用在 基板 1后,对基板 1的移动所产生的推动效果和阻碍效果正好能够全部抵消, 更大程度地减小了液体的沖击对基板 1在运输设备上运行速度的影响。
图 3示出了本发明实施例一的一种变体提供的一种基板清洗装置, 其与 图 1所示的实施例的区别在于驱动系统 4的布置略有不同。
请参考图 1、 3, 例如, 本发明实施例提供的基板清洗装置的驱动系统 4 包括: 驱动电机 41 ; 驱动多个传动齿轮 3往复转动的传动机构 42,传动机构 42的动力输入端与驱动电机 41的输出轴传动连接。
驱动电机 41作为动力输出设备,驱动电机 41的输出轴通过传动机构 42 将动力传输给各传动齿轮 3 ,通过传动机构 42带动各传动齿轮 3实现轴向往 复运动。
请参考图 1、 图 3, 例如, 传动机构 42包括: 与驱动电机 41的输出轴同 轴固定的主动轮 421;—端与主动轮 421铰接的连杆 422; 与连杆 422另一端 铰接的过渡齿轮 423,主动轮 421、连杆 422以及过渡齿轮 423形成四连杆机 构; 与多个传动齿轮 3、过渡齿轮 423连接的传送皮带 424; 至少一个用于张 紧传送皮带 424的张紧轮 425。
连杆 422的两端分别转动地连接一个与连杆 422垂直的销轴(图中未示 出) 。 连杆 422—端的销轴固定在主动轮 421上, 另一端的销轴固定在过渡 齿轮 423上, 从而将连杆 422铰接在主动轮 421和过渡齿轮 423之间, 使得 主动轮 421、 连杆 422以及过渡齿轮 423形成一个四连杆机构。 驱动电机 41 通过该四连杆机构可以带动过渡齿轮 423在一定角度范围内轴向往复转动, 从而带动与过渡齿轮 423连接的传送皮带 424往复运动, 传送皮带 424往复 运动的同时带动与其连接的各传动齿轮 3轴向往复转动。 每一个传动齿轮 3 轴向固定的一个喷淋管道 2随该传动齿轮 3—起往复转动, 从而带动从喷淋 管道 2的喷液口 21持续喷出的液体往复摆动, 使得液体从喷液口 21喷出的 方向与下方放置的基板 1之间的角度发生规律性变化, 提高了基板清洗装置 对基板表面的清洁效果, 且减小了液体对基板运行速度的影响。 调整各传动齿轮 3的往复转动方向, 以改变喷淋管道 2的往复转动方向。
请继续参考图 1、 图 3 , 例如, 多个传动齿轮 3形成依次相邻的若干个齿 轮组 31 , 任意相邻的两个齿轮组 31中的传动齿轮 3上的传送皮带 424绕向 相反。
驱动电机 41通过主动轮 421、连杆 422以及传送皮带 424形成的四连杆 机构驱动传送皮带 424往复运动, 传送皮带 424往复运动的同时带动传动齿 轮 3轴向往复转动。 在传送皮带 424沿一个方向运动时, 传送皮带 424绕向 相反的传动齿轮 3的转动方向相反, 转动方向相反的传动齿轮 3带动的喷淋 管道 2的转动方向也相反, 从而使得转动方向相反的两部分喷淋管道 2中的 液体从喷液口 21喷出的方向相反,喷出方向相反的液体对基板 1的推动效果 和阻碍效果相互抵消, 减小了液体的沖击对基板 1在运输设备上运行速度的 影响。
请继续参考图 1、 图 3 , 例如, 上述每一个齿轮组 31包括至少一个传动 齿轮 3。
更具体地, 如图 1中所示, 上述每一个齿轮组 31包括一个传动齿轮 3, 任意相邻的两个传动齿轮 3上的传送皮带 424绕向相反。 如图 3中所示, 上 述每一个齿轮组 31包括两个传动齿轮 3, 同一个齿轮组 31中的两个传动齿 轮 3上的传送皮带 424的绕向相同,任意相邻的两个齿轮组 31的传动齿轮 3 上的传送皮带 424绕向相反。
图 4为本发明实施例二提供的基板清洗装置中第二种传动机构的结构示 意图。 图 5为本发明实施例三提供的基板清洗装置中第三种传动机构的结构 示意图。 图 7为本发明实施例四提供的基板清洗装置中第四种传动机构的结 构示意图。 请参考图 4、 5和 7, 多个传动齿轮 3形成若干个分别具有两个相 互啮合的传动齿轮的齿轮组 32。
如图 4、 5所示, 齿轮组 32中的齿轮 321和齿轮 322相互啮合; 传动机 构 42包括:形成曲柄滑块机构的主动轮 421、连杆 422、滑轨 426和推杆 427, 以及连接推杆 427与每一个齿轮组 32中的一个传动齿轮 3、将推杆 427的直 线运动转换为传动齿轮 3的周向运动的转换机构。主动轮 421与驱动电机 41 的输出轴同轴固定;连杆 422的一端与主动轮 421铰接,而另一端与推杆 427 的一端铰接; 滑轨 426与壳体相对固定、 且沿基板 1移动方向 a延伸; 推杆 427滑动装配于滑轨 426。
连杆 422的两端分别转动地连接一个与连杆 422垂直的销轴, 连杆 422 一端的销轴固定在主动轮 421上, 连杆 422另一端的销轴固定在推杆 427的 一端, 从而将连杆 422铰接在主动轮 421和推杆 427之间, 由于推杆 427滑 设于滑轨 426内, 从而使得主动轮 421、 连杆 422以及过渡齿轮 423形成一 个曲柄滑块机构。驱动电机 41通过该曲柄滑块机构驱动推杆 427在滑轨 426 内沿直线往复运动,推杆 427通过转换机构带动齿轮组 32中的一个传动齿轮 321轴向往复转动, 由于同一齿轮组 32中的传动齿轮 321和传动齿轮 322相 互啮合, 所以传动齿轮 321和传动齿轮 322—起同频率反方向往复转动, 从 而将推杆 427的直线运动转换为传动齿轮 321的周向运动。 任意一个齿轮组 32中的传动齿轮 321和传动齿轮 322分别连接的喷淋管道 2的往复转动方向 相反, 从而使得往复转动方向相反的两部分喷淋管道 2的数量相同, 更大程 度地减小了液体的沖击对基板 1在运输设备上运行速度的影响。
图 6为基板清洗装置中另一种驱动系统的驱动原理示意图, 例如可用于 替换如图 4以及图 5所示实施例的基板清洗装置中的驱动系统。
请参考图 6,驱动多个传动齿轮 3往复转动的传动机构 42包括形成凸轮 连杆机构的凸轮 5、滑轨 426和推杆 427, 以及连接推杆 427和每一个齿轮组 32中的一个传动齿轮 321、 将推杆 427的直线运动转换为传动齿轮 3的周向 运动的转换机构凸轮 5安装于驱动电机 41的输出轴;滑轨 426与壳体相对固 定、且沿基板 1移动方向 a延伸;推杆 427与滑轨 426配合滑动,且推杆 427 的一端配合安装于凸轮 5。
驱动电机 41的输出轴安装一个具有导向槽 51的凸轮 5, 推杆 427滑设 于滑轨 426内、且一端通过一滚轮配合安装于凸轮 5的导向槽 51内,使得凸 轮 5、 推杆 427和滑轨 426形成一个凸轮连杆机构。 驱动电机 41通过凸轮连 杆机构驱动推杆 427在滑轨 426内沿直线往复运动, 推杆 427通过转换机构 带动齿轮组 32中的一个传动齿轮 321轴向往复转动,同时传动齿轮 321带动 与其啮合的另一传动齿轮 322轴向往复转动,且传动齿轮 321和传动齿轮 322 的往复转动方向相反, 从而将推杆 427的直线运动转换为多个传动齿轮 3的 周向运动。
再请参考图 4, 实施例二的基板清洗装置的转换机构包括: 推杆 427上 设置的垂直于基板的滑槽 428;—端固定于齿轮组 32中的一个传动齿轮 321 , 另一端伸入滑槽 428的滑杆 429。 由于滑杆 429的一端固定于齿轮组 32中的 一个传动齿轮 321 , 使得滑杆 429的运动方向必须与传动齿轮 321的转动方 向一致, 而且滑杆 429的另一端伸入滑槽 428内, 因此在推杆 427带动滑杆 429沿推杆 427的运动方向往复运动的同时,滑杆 429在推杆 427的滑槽 428 内还会相对于推杆 427上、 下往复运动, 从而将推杆 427的直线运动转换为 传动齿轮 321的周向运动。
请参考图 5 , 实施例三与实施例二的区别在于基板清洗装置的转换机构, 该实施例三的基板清洗装置的转换机构包括: 设置于推杆 427朝向传动齿轮 3的一侧、 与每一个齿轮组 32中的一个传动齿轮 321啮合的齿条 6。 传动齿 轮 321啮合的齿条 6构成一个转换机构, 推杆 427通过齿条 6带动每一个齿 轮组 32中与齿条 6啮合的传动齿轮 321轴向往复转动,从而将推杆 427的直 线运动转换为多个传动齿轮 3的周向运动。
请参考图 7, 实施例四中, 多个传动齿轮 3形成若干个分别具有两个相 互啮合的传动齿轮的齿轮组 32; 如图 7所示, 齿轮组 32中的齿轮 321和齿 轮 322相互啮合; 传动机构 42包括主动轮 421、 连杆 422和推杆 427, 以及 连接推杆 427与每一个齿轮组 32中的一个传动齿轮 3、将推杆 427的直线运 动转换为传动齿轮 3的周向运动的转换机构。主动轮 421与驱动电机 41的输 出轴同轴固定; 连杆 422的一端与主动轮 421铰接, 另一端与推杆 427的一 端铰接。 该实施例中的转换机构包括: 推杆 427具有的圓孔; 一端固定于齿轮组 32中的一个传动齿轮 321 , 另一端插入推杆 427的圓孔中、 且与圓孔转动配 合的滑杆 429。
连杆 422的两端分别转动地连接一个与连杆 422垂直的销轴, 连杆 422 一端的销轴固定在主动轮 421上, 连杆 422另一端的销轴固定在推杆 427的 一端, 从而将连杆 422铰接在主动轮 421和推杆 427之间; 传动齿轮 321固 定的滑杆 429插入推杆 427的圓孔中构成一个转换机构。驱动电机 41通过主 动轮 421和连杆 422推动推杆 427往复运动, 推杆 427在往复运动的同时通 过滑杆 429带动齿轮组 32中的一个传动齿轮 321轴向往复转动,由于同一齿 动齿轮 322会一起同频率反方向往复转动, 从而将推杆 427的直线运动转换 为传动齿轮 321的周向运动。
请参考图 2, 对于本发明的实施例, 每一个喷淋管道 2上间隔设置若干 个喷嘴 7,形成喷液口 21;相邻喷淋管道 2上的喷液口 21可以彼此相对或相 错开设置。 喷嘴 7可以通过螺纹连接或焊接或其它连接方式设置在喷淋管道 2上, 每一个喷嘴 7形成一个喷液口 21。 脱离本发明的精神和范围。 这样, 倘若本发明的这些修改和变型属于本发明 权利要求及其等同技术的范围之内, 则本发明也意图包含这些改动和变型在 内。
