Description

一种玻璃基板传送装置及检测被传动轴转动同步性的方法
【技术领域】
本发明涉及显示技术领域，特别是涉及一种玻璃基板传送装置及检测被传动轴转动同步性的方法。
【背景技术】
液晶面板生产过程中，在对TFT-LCD玻璃基板传送时，一般采用传送带（Conveyor）作为传送装置进行流片，目前的传送带主要采用聚甲醛树脂（POM）及铁氟龙等低发尘防静电滚轮进行玻璃传送。
在对玻璃传送过程中，要求平稳流片、无抖动、无流偏且玻璃基板无划伤，这就要求各个被传送轴相对速度相同，并且各滚轮与玻璃接触点在同一等高面。通常可以通过调整来保证各滚轮与玻璃接触点的高度在允许的误差范围内，但是，各被传动轴则可能受磁力的主传动轮品质差异、现场撞击以及温度骤变等因素而不能保证同步。
玻璃基板依靠滚动摩擦力进行传送，传送过程中，当某一被传动轴因故障停止转动或转速与其它被传动轴不同步时，该被传动轴上的滚轮与玻璃基板接触点处产生滑动摩擦力。一方面，当滑动摩擦力远大于滚动摩擦力时，可能会在玻璃上留下痕迹或刮伤产品，另一方面，新增的滑动摩擦力破坏了玻璃基板的力平衡，并使玻璃基板发生抖动和流偏，从而造成玻璃基板破片。
当各被传动轴转动不同步产生滑动摩擦力时，仅凭肉眼很难察觉，一般很难及时发现，目前往往是出现破片或者不良品后去检测才知道设备需要维修。
因此，有必要提供一种玻璃基板传送装置及检测被传动轴转动同步性的方法，以解决现有技术的玻璃基板传送带无法快速检测各个被传动轴的转动是否同步的技术问题。

图7是本发明实施例的玻璃基板传送方法的流程图。
【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
图1是本发明实施例的玻璃基板传送装置的结构示意图。如图1所示，玻璃基板传送装置1包括多个被传动轴10、多个滚轮20、反射板30以及红外线传感单元40。
其中，多个被传动轴10沿第一方向X平行间隔设置并沿第二方向Y延伸，并在第一方向X上设置有贯穿被传动轴10的通孔11，第一方向X与第二方向Y垂直。通孔11用于供红外线穿过，通孔11的尺寸根据被传动轴10的直径和红外线的要求而设置。在安装被传动轴10时，需要将各个被传动轴10上的通孔11对齐，以使各个对齐的通孔11能形成一个供红外线穿过的通道。
多个滚轮20沿第二方向Y间隔固定在被传动轴10上，滚轮20用于承载玻璃基板2，并随被传动轴10的转动而转动以传动玻璃基板2流动。本实施例中，滚轮20由聚甲醛树脂或铁氟龙等低发尘且防静电的材料制成，滚轮20通过滚动摩擦力驱动玻璃往前流动。
反射板30沿第一方向X设置在被传动轴10的一侧，其用于反射红外线。
红外线传感单元40沿第一方向X设置在被传动轴10的另一侧。通孔11及反射板30皆位于红外线传感单元40发出的红外线的传播方向上。红外线传感单元40用于发出红外线，并接收红外线传感单元40所发射出的红外线经障碍物反射回的反射光，并根据反射光的强度值判断多个被传动轴10转动的同步性。
图2是图1中红外线传感单元40的结构示意图。如图2所示，本实施例中的红外线传感单元40包括发射模块41、接收模块42、判断模块43以及告警模块44。
其中，发射模块41用于发射红外线，发射模块41例如为红外发射电路等。接收模块42用于接收发射模块41发射出的红外线经障碍物反射回的反射光，接收模块42例如为红外接收模块等。
图3是图1中玻璃基板传送装置的被传动轴10转动同步时的局部放大图，图4中图3中玻璃基板传送装置的左侧视图。如图3、4所示，当各个被传动轴10转动同步时，各个通孔11对齐并形成一个供红外线通过的通道，红外线传感单元40发射的红外线穿过各个通孔11形成的通道到达反射板30，并经反射板30反射回红外线传感单元40。
图5是图1中玻璃基板传送装置的被传动轴10转动不同步时的局部放大图，图6是图4中玻璃基板传送装置的左侧视图。如图5、6所示，当各个被传动轴10转动不同步或者某一被传动轴10转动停止时，红外线传感单元40发射的红外线只能穿过部分通孔11，并被转动不同步或转动停止的被传动轴10反射回红外线传感单元40。
如图4、6所示，可在滚轮20上进一步设置转动标记21，在安装滚轮20时，将第一方向X上处于同一排的所有滚轮20按照转动标记21对齐，然后将滚轮20固定于被传动轴10上，以便于通过肉眼判断各个滚轮20转动是否同步。
判断模块43与接收模块42连接，判断模块43用于根据反射光的强度值判断多个被传动轴10的转动是否同步。由于接收模块42接收的反射光强随反射物体（即障碍物）的距离变化而变化，反射物体的距离近则反射光强，距离远则反射光弱，判断模块43可根据反射光的强度值判断障碍物的距离，反射光的强度值越大则障碍物的距离越近，因此，据此可以判断前方是否有被传动轴10转动不同步，并可进一步根据反射光的强弱判断转动不同步的被传动轴10的距离，并根据不同的距离判定哪根被传动轴10的转动不同步。
本实施例中，判断模块43存储有多个预设反射光强度值，每一预设反射光强度值分别对应于多个被传动轴10及反射板30反射红外线发射模块40发出的红外光的强度值。
判断模块43判断反射光的强度值与对应于反射板30的预设反射光强度值是否匹配，若匹配，则判断模块43判断该多个被传动轴10的转动为同步，若不匹配，则判断模块43判断该多个被传动轴10的转动为不同步。当判断该多个被传动轴10的转动为不同步时，判断模块43根据反射光的强度值搜索与其匹配的预设反射光强度值，并根据搜索到的匹配的预设反射光强度值判断与其对应的被传动轴10的转动为不同步。
当判断模块43判断该多个被传动轴10的转动为不同步时，告警模块44发出告警以提醒用户检修玻璃基板传送装置1。
请再参考图1，在本实施例中，玻璃基板传送装置1还进一步包括驱动单元50，驱动单元50用于驱动被传动轴10转动。本实施例中，驱动单元50包括主传动轴51、多个主传动轮52以及多个被传动轮53。
其中，主传动轴51的延伸方向垂直于被传动轴10的延伸方向，主传动轴51可转动，多个被传动轴10沿主传动轴51的延伸方向间隔排列设置。多个主传动轮52沿主传动轴51的延伸方向间隔固定在主传动轴51上，并随主传动轴51的转动而转动，且主传动轮52具有磁性。被传动轮53也具有磁性，每一被传动轮53固定在每一被传动轴10的非通孔区域且靠近主传动轴51的一端上，被传动轮53由主传动轮52通过磁耦合作用驱动而转动，并最终带动被传动轴10转动。
图7是本发明实施例的玻璃基板传送方法的流程图。如图7所示，本发明实施例的检测玻璃基板传送装置中被传动轴转动的同步性的方法包括：
步骤S1：在沿第一方向平行间隔设置的多个被传动轴上沿第一方向设置贯穿被传动轴的通孔，多个被传动轴沿第二方向延伸，且第一方向与第二方向垂直；
步骤S2：沿第一方向，在多个被传动轴的两侧分别提供红外线传感单元和发射板，且通孔及反射板位于红外线传感单元发出的红外线的传播方向上；
步骤S3：利用红外线传感单元发出红外线，且接收其所发射出的红外线经障碍物反射回的反射光；
步骤S4：根据反射光的强度值判断多个被传动轴转动的同步性。
其中，步骤S4包括：根据反射光的强度值判断障碍物的距离，反射光的强度值越大则障碍物的距离越近。
在本实施例中，步骤S4包括：存储多个预设反射光强度值，每一预设反射光强度值分别对应于多个被传动轴及反射板反射红外线发射模块发出的红外光的强度值；判断反射光的强度值与对应于反射板的预设反射光强度值是否匹配，若匹配，则判断多个被传动轴的转动为同步，若不匹配，则判断多个被传动轴的转动为不同步，当判断多个被传动轴的转动为不同步时，步骤S4还包括：根据反射光的强度值搜索与其匹配的预设反射光强度值，并根据搜索到的匹配的预设反射光强度值判断与其对应的被传动轴的转动为不同步。
通过上述方式，本发明的玻璃基板传送装置及检测被传动轴转动同步性的方法通过在各被传动轴两侧设置红外线传感单元和发射板，能够及时检测各被传动轴的转动是否同步或者停止，避免玻璃基板产生刮伤或破片。
以上所述仅为本发明的实施例，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。
