Description

一种玻璃基板清洗机
【技术领域】
本发明涉及玻璃制造领域，特别是涉及一种玻璃基板清洗机。

显示屏的玻璃基板在制程过程中的投入及关键制程前均需要进行彻底清洗。请参阅图1，图1是现有技术的玻璃基板清洗机的结构示意图，如图1所示，现有技术的玻璃基板清洗机10包括风刀101、多个间隔设置的滚轴102以及间隔套设在每一滚轴102上的多个滚轮103。其中，风刀101包括上风刀111和下风刀112。滚轮103在玻璃基板20的下方支撑并传送玻璃基板20，将玻璃基板20向前推进到风刀101处。
目前，玻璃基板20越来越薄、越来越轻。因此，在传送过程中，玻璃基板20遇到下方的风或较大的清洗液压力时容易浮起。进一步的，在到达风刀101前由于上风刀111和下风刀112实时压力、风速、稳定性存在一定差异，使得玻璃基板20抖动，而玻璃基板20抖动又会进一步产生乱流，因此，加剧玻璃基板20的抖动，当抖动范围超出上风刀111和下风刀112之间的狭缝时，玻璃基板20将会撞击风刀101从而造成破损。而破损通常需要进行现场调查、设备诊断调节、破板清理、试生产、恢复生产等约2-3小时的处理。因此，降低了玻璃基板的良率以及产量，提高了生产成本。
【发明内容】
本发明主要解决的技术问题是提供一种玻璃基板清洗机，能够降低玻璃基板的破损率，提高玻璃基板的产量及良率。
为解决上述技术问题，本发明采用的一个技术方案是：提供一种玻璃基板清洗机，其包括：风刀，用于吹干玻璃基板；传送装置，其包括用于承载并传送玻璃基板的主传送滚轮组，其中：传送装置还包括辅传送滚轮组，辅传送滚轮组设置在风刀的前侧并位于主传送滚轮组的上方，其中：辅传送滚轮组和主传送滚轮组上下联动以夹持玻璃基板朝向风刀的方向向前推进；辅传送滚动组设置在距离风刀的前侧的400毫米至20毫米的位置处；风刀包括上风刀和下风刀，上风刀到下风刀的垂直距离大于或者等于辅传送滚轮组到主传送滚轮组的垂直距离。
其中，主传送滚轮组和辅传送滚轮组分别包括多条平行间隔设置的滚轴和多个间隔套设在每一滚轴上的滚轮。
其中，风刀的前后两侧均设置有主传送滚轮组，位于风刀的前侧的主传送滚轮组包括第一传送滚轮组和第二传送滚轮组，其中，第一传送滚轮组位于辅传送滚轮组的下方，第二传送滚轮组与第一传送滚轮组相接且更远离风刀的前侧，第一传送滚轮组的相邻两个滚轴之间的距离为D1，第二传送滚轮组的相邻两个滚轴之间的距离为D2，其中，D1小于D2。
其中，辅传送滚轮组的相邻两个滚轴之间的距离为D3，其中，D3等于D1。
其中，D1的取值等于D2的三分之二。
其中，D1等于80毫米，D2等于120毫米。
其中，辅传送滚轮组的滚轴与主传送滚轮组的滚轴在水平方向交错设置。
其中，辅传送滚轮组的滚轴设置在主传送滚轮组的两个相邻的滚轴的水平轴线上。
其中，玻璃基板清洗机进一步包括相对设置的两侧板，侧板用于固定滚轴的两端。
为解决上述技术问题，本发明采用的又一个技术方案是：提供一种玻璃基板清洗机，其包括：风刀，用于吹干玻璃基板；传送装置，其包括用于承载并传送玻璃基板的主传送滚轮组，其中：传送装置还包括辅传送滚轮组，辅传送滚轮组设置在风刀的前侧并位于主传送滚轮组的上方，其中，辅传送滚轮组和主传送滚轮组上下联动以夹持玻璃基板朝向风刀的方向向前推进。
其中，辅传送滚动组设置在距离风刀的前侧的400毫米至20毫米的位置处。
其中，主传送滚轮组和辅传送滚轮组分别包括多条平行间隔设置的滚轴和多个间隔套设在每一滚轴上的滚轮。
其中，风刀的前后两侧均设置有主传送滚轮组，位于风刀的前侧的主传送滚轮组包括第一传送滚轮组和第二传送滚轮组，其中，第一传送滚轮组位于辅传送滚轮组的下方，第二传送滚轮组与第一传送滚轮组相接且更远离风刀的前侧，第一传送滚轮组的相邻两个滚轴之间的距离为D1，第二传送滚轮组的相邻两个滚轴之间的距离为D2，其中，D1小于D2。
其中，辅传送滚轮组的相邻两个滚轴之间的距离为D3，其中，D3等于D1。
其中，D1的取值等于D2的三分之二。
其中，D1等于80毫米，D2等于120毫米。

图1是现有技术的玻璃基板清洗机的结构示意图；
图2是本发明玻璃基板清洗机实施例的结构示意图；
图3是图2所示的玻璃基板清洗机的辅传送滚轮组和第一传送滚轮组的设置高度的示意图。
【具体实施方式】
请参阅图2，图2是本发明玻璃基板清洗机实施例的结构示意图，如图2所示，本发明的玻璃基板清洗机200包括风刀201以及传送装置202。
其中，风刀201通过压缩空气驱动，以形成一面薄薄的高强度、大气流的冲击风幕，用以吹干玻璃基板300。
本实施例中，风刀201的材质优选为铝合金或者不锈钢。
传送装置202包括分别设置在玻璃基板300上下两侧的主传送滚轮组221和辅传送滚轮组222。其中，主传送滚轮组221用于承载并传送玻璃基板300，其分别设置在风刀201的前后两侧并且位于玻璃基板300的下方。辅传送滚轮组222设置在风刀201的前侧，并位于主传送滚轮组221的上方。优选为，辅传送滚轮组222设置在风刀201的前侧的400毫米至20毫米的位置处，使得在风刀201的前侧，辅传送滚轮组222和主传送滚轮组221上下联动以夹持玻璃基板300朝向风刀201的方向向前推进。
具体的，位于风刀201的前侧的主传送滚轮组221包括第一传送滚轮组223和第二传送滚轮组224。其中，第一传送滚轮组223位于辅传送滚轮组222的下方，第二传送滚轮组224与第一传送滚轮组223相接且更远离风刀201的前侧。
本实施例中，主传送滚轮组221和辅传送滚轮组222分别包括多条平行间隔设置的滚轴225和多个间隔套设在每一滚轴225上的滚轮226。其中，滚轮226对玻璃基板300起到支撑的作用，并且滚轮226相对于滚轴225转动，以此传送玻璃基板300。
本实施例中，第一传送滚轮组223的相邻两个滚轴225之间的距离为D1，第二传送滚轮组224的相邻两个滚轴225之间的距离为D2，辅传送滚轮组222的相邻两个滚轴225之间的距离为D3。其中，为了增加玻璃基板300的平稳度，本实施例采取增加玻璃基板300的支撑点的方案，即：设置第一传送滚轮组223的相邻两个滚轴225之间的距离D1小于第二传送滚轮组224的相邻两个滚轴225之间的距离D2，以此增加滚轴225的设置密度，进而增加滚轮226的设置数量，从而在靠近风刀201的不稳定区域使得玻璃基板300的支撑点位变得更为密集。可以理解的是，设置辅传送滚轮组222的相邻两个滚轴225之间的距离D3等于第一传送滚轮组223的相邻两个滚轴225之间的距离D1，能够使得玻璃基板300的平稳效果更好。
本发明实施例中，D1和D3的取值等于D2的三分之二。并且，D1和D3优选等于80毫米，D2优选等于120毫米。
进一步的，辅传送滚轮组222的滚轴225与主传送滚轮组221的滚轴225在水平方向交错设置。本实施例中，辅传送滚轮组222的滚轴225优选与第一传送滚轮组223的滚轴225在水平方向交错设置。具体的，辅传送滚轮组222的滚轴225设置在第一传送滚轮组223的两个相邻的滚轴225的水平轴线上。使得玻璃基板300能够均匀地受到辅传送滚轮组222和第一传送滚轮组223的夹持作用，从而进一步增加玻璃基板300传送的平稳度。
本实施例中，在风刀201的前侧，位于玻璃基板300上下两侧的辅传送滚轮组222和第一传送滚轮组223的设置高度关系如图3所示，其中，风刀201包括上风刀211和下风刀212，其中，上风刀211到下风刀212的垂直距离H1大于或者等于辅传送滚轮组222到第一传送滚轮组223的垂直距离H2。而辅传送滚轮组222到第一传送滚轮组223的垂直距离H2略大于玻璃基板300的厚度。
本实施例中，玻璃基板清洗机200进一步包括相对设置的两侧板203，侧板203用于固定滚轴225的两端。具体的，在侧板203上设置了多个与滚轴225两端的形状对应的通孔231，滚轴225的两端分别设置在通孔231中进行固定。
承前所述，玻璃基板300通过辅传送滚轮组222和主传送滚轮组221配合传送，在风刀201前侧抖动范围较小，能够顺利通过风刀201，降低玻璃基板300的破损率。具体的工作过程为：
首先，第二传送滚轮组224支撑玻璃基板300，并通过滚轮226向风刀201的方向联动，以将玻璃基板300朝向风刀201的方向向前推进。当到达风刀201前侧的位置处时，第一传送滚轮组223和辅传送滚轮组222上下联动以夹持玻璃基板300继续前进。此时，由于上风刀211和下风刀212的实时压力、风速以及稳定性存在一定的差异，因此，玻璃基板300会受到来自风刀201的风的不均匀撞击而产生抖动。但是，因为玻璃基板300受到辅传送滚轮组222和第一传送滚轮组223的上下夹持，因此，玻璃基板300的抖动能够保持在较小范围内。又因为上风刀211到下风刀212的垂直距离H1大于或者等于辅传送滚轮组222到第一传送滚轮组223的垂直距离H2，因此，保证了玻璃基板300在传送过程中不会撞击到风刀201。进一步的，玻璃基板300的抖动保持在较小的范围内，使得玻璃基板清洗机200中的清洗液和玻璃基板300的接触面积较大，因此，更好地对玻璃基板300进行清洗。
综上所述，本发明的玻璃基板清洗机通过在风刀的前侧设置密集的支撑点位并增加位于主传送滚轮组的上方的辅传送滚轮组，使得玻璃基板可稳定传送同时限制玻璃基板的抖动范围，从而可以避免撞击风刀而造成破损。因此，降低了玻璃基板的破损率，提高了玻璃基板的良率以及产量。另外，玻璃基板的抖动保持在较小的范围内，进一步使得玻璃基板清洗机能更好地对玻璃基板进行清洗，因此，进一步提高了玻璃基板清洗机的清洗效果。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
