【附图说明】
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图，其中：
图1是与本发明相关的一种玻璃基板歪斜放置在收纳箱内的结构示意图；
图2是本发明优选实施例基板解包装置的结构示意图；
图3是图2所示基板解包装置的高度探测传感器的放大结构示意图；
图4是本发明当玻璃基板歪斜放置在收纳箱内时吸附组件停止下降的示意图。
【具体实施方式】
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明的一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本发明实施例公开了一种基板解包装置，请参阅图2，所述基板解包装置2可以用来将隔板3和玻璃基板4从收纳箱5中取出，例如先将所述隔板3取出放入旁边的另一个收纳箱（图未示）中回收利用，然后再将所述玻璃基板4取出以作目标用途。其中，所述玻璃基板4和所述隔板3都平放在所述收纳箱5中，所述隔板3设置在所述玻璃基板4上方，两者之间的间距较小，有时甚至接近真空状态。
所述基板解包装置2包括连接板20、多个吸附组件21和多个高度检测传感器23，所述多个高度检测传感器23分别设置在所述连接板20和所述多个吸附组件21之间。
所述吸附组件21用于吸附目标物体，例如吸附所述玻璃基板4和所述隔板3。请参阅图3，所述吸附组件21包括导杆210、弹簧212和吸附末端214。其中，所述导杆210的一端与所述高度检测传感器23连接，所述导杆210的另一端与所述吸附末端214连接，所述弹簧212套设在所述导杆210上，并位于所述吸附末端214与所述高度检测传感器23之间。在本实施例中，所述多个吸附末端214与所述连接板20之间的距离相同，所述吸附末端214为吸盘，针对不同材料的目标物体，所述吸附末端214可以对应更换为吸力较好的元件。
其中，当所述弹簧212处于自然状态时，所述传感器23处于关闭状态。当所述弹簧212处于收缩状态时，所述传感器23处于开启状态。
当所述吸附末端214下降以吸附目标物体时，所述多个高度检测传感器23的状态同步，则所述基板解包装置2的工作过程正常。
当所述吸附末端214下降以吸附目标物体时，所述多个高度检测传感器23中至少一个与其它所述高度检测传感器23的状态不同步时，例如其中一个或者两个高度检测传感器23处于开启状态，而其余的高度检测传感器23处于关闭状态时，则所述基板解包装置2的工作过程异常，此时所述吸附末端214停止向所述目标物体方向移动。此外，所述基板解包装置2还包括警报单元（图未示），当所述基板解包装置2的工作过程异常时，所述警报单元发出报警，可以提醒操作人员人工处理。
所述基板解包装置2还设计了容错功能。其中，所述多个高度检测传感器23的状态同步判断设有预设的延时，在预设的延时范围内，忽略所述多个高度检测传感器23的状态同步差异。即，在延时范围内，如果其中一个或者两个高度检测传感器23处于开启状态，而其余的高度检测传感器23处于关闭状态时，则此时仍然判定所述基板解包装置2的工作过程正常，以允许所述玻璃基板4处于平放在所述收纳箱5情况下，所述多个吸附末端214到达所述玻璃基板4的表面的时间的细微差异。在预设的延时范围外，所述多个高度检测传感器23的状态同步差异被即时判断。即，在延时范围外，如果其中一个或者两个所述高度检测传感器23处于开启状态，而其余的所述高度检测传感器23处于关闭状态时，则此时立刻判定所述基板解包装置2的工作过程异常，马上停止所述吸附末端214向所述玻璃基板4方向移动以保护所述玻璃基板4，并发出报警提醒操作人员及时处理。
在本实施例中，所述吸附组件21的数量为四个，其可以分别吸附目标物体的四个角落处。当然，所述吸附组件21的数量也可以为两个，如此分别可以吸附目标物体的中心轴对称位置。所述吸附组件21的数量还可以为三个，如此可以分别吸附目标物体的稳定三角位置。根据实际需求，所述吸附组件21的数量还可以为六个、八个或者其它合适的数量。
当利用所述基板解包装置2来进行解包吸附时，首先，所述吸附末端214吸附位于上层的所述隔板3的表面，并将其向上提起。此时，如果所述玻璃基板4没有跟随所述隔板3被一并带起，则后续对所述玻璃基板4的吸附过程正常操作。
还有一种情况是，所述玻璃基板4跟随所述隔板3被一并带起，并在向上运动过程中歪斜放置在所述收纳箱5内，请参阅图4。此时，已经将所述隔板3吸走并放置到其它地方的吸附末端214回到所述收纳箱5上方，并向下运动来吸附所述玻璃基板4。由于所述玻璃基板4歪斜放置在所述收纳箱5内，所以所述多个吸附末端214到达所述玻璃基板4的顺序相异，其中对应所述玻璃基板4抬高处的吸附末端214首先到达所述玻璃基板4，而其余的吸附末端214则滞后到达所述玻璃基板4。首先到达所述玻璃基板4的所述吸附末端214对应的所述高度检测传感器23的弹簧212接下来会产生形变而收缩，并开启所述高度检测传感器23。根据所述基板解包装置2的设计，其余的所述高度检测传感器23的弹簧212此时仍未产生形变，并没有开启其余对应的所述高度检测传感器23。也就是说，此时所有的所述高度检测传感器23的状态并不同步，且这种同步差异在预设的延时范围外，这种情况下，所述吸附末端214马上停止向所述玻璃基板4方向移动，并且所述警报单元发出报警。因此，虽然所述玻璃基板4歪斜放置在所述收纳箱5内，但由于所有的所述高度检测传感器23的状态并不同步，而且同步差异在预设的延时范围之外，所以可以避免由于所述吸附末端214的继续下降而导致所述玻璃基板4破片，同时保护了所述吸附末端214受到机械损坏。
此外，本发明实施例的所述基板解包装置2的除了可以用来吸附所述玻璃基板4外，还可以用来吸附其它合适材料的基板。
区别于现有技术的情况，本发明实施例的基板解包装置具有以下的有益效果：由于所述基板解包装置包括所述高度检测传感器和所述吸附组件，通过所有高度检测传感器的同步差异来判定玻璃基板是否歪斜放置在收纳箱内，以避免玻璃基板破片和保护吸附组件机械损坏。
综上所述，本发明实施例的基板解包装置具有减少基板破片和保护机构避免损坏等优点。
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它相关的技术领域，均同理包括在本发明的专利保护范围内。
