所述基准高度值H2即为显示面板50的中部平板区域（没有翘曲的区域）与距离传感器30之间的高度值，可以预先测量，也可以在检测中进行检测。
本申请技术方案通过检测平台10承载传输所述显示面板50，使显示面板50的一端临接距离传感器30，然后距离传感器30检测显示面板50的端部与距离传感器30之间的第一高度值H1，控制器70将所述第一高度值H1与基准高度值H2做差，若第一高度值H1与基准高度值H2的差值△H大于预设阈值H时，则证明所述显示面板50的端部的弯曲度过高，达不到使用的需求，进而所述检测装置100发出警示，提醒操作人员。如此，通过所述检测装置100，即可方便快捷的检测显示面板50的弯曲度是否达到使用需求，减少人工检测的工序，降低人工成本。
在实施例中，所述预设阈值H的范围值为：0.5mm≤H≤1mm。所述预设阈值H的设定根据不同的显示面板50的尺寸进行设置，大规格的显示面板50其允许翘曲的高度值高一些，小规格的显示面板50其允许翘曲的高度值低一些。综合现有规格的显示面板50，其允许翘曲的高度值在0.5mm至1mm。
在实施例中，所述距离传感器30为红外传感器或超声波传感器。红外传感器通过发射红外线进行测距，超声波传感器通过发射超声波进行测距，当然，还可以包含其他传感器，也在本申请的保护范围内。
参照图1和图2，在本申请的一实施例中，所述检测平台10包括安装架和安装于所述安装架（未图示）的至少两间隔设置的滚筒11，所述距离传感器30安装于所述安装架，并位于两所述滚筒11之间。两滚筒11的上侧边位于同一水平面，可以通过电机驱动滚筒11转动，带动显示面板50传动。通过将距离传感器30位于两滚筒11之间，同时位于显示面板50的下方，可方便检测。
进一步地，所述基准高度值H2的范围值为：15cm≤H2≤20cm。也即，距离传感器30相对于显示面板50中部平板区域的高度为15cm~20cm。距离传感器30在安装架中距离显示面板50中部平板区域过近会影响安装空间，过远或影响检测的灵敏度。因此，设置在15cm~20cm可兼顾安装空间和检测的灵敏度。
在本实施例中，所述检测装置100还包括发出警示信息或警示音的报警器（未图示），所述报警器与所述控制器70电性连接。
所述报警器发出的警示可为文字警示信息，也可为警示音，通过警示信息或警示音使得操作者得知面板不符合使用的需求，进而进行下一步操作。
在本实施例中，所述检测装置100还包括触控显示器80，所述触控显示器与所述控制器70电性连接。通过触控显示器80，可以实现触控操作，如输入预设阈值H，操作检测装置100开启或停止等，也可以显示显示面板50的检测数据。
本申请还提供一种显示面板的检测方法，
步骤S10：传输显示面板50，使显示面板50的一端临接一距离传感器30；
步骤S20：距离传感器30检测所述显示面板50的端部与距离传感器30之间的第一高度值H1，并将第一高度值H1发送至一控制器70；
步骤S30：所述控制器70将第一高度值H1与基准高度值H2做差，若差值△H大于预设阈值H时，则发出警示。
本方法通过检测平台10承载传输所述显示面板50，使显示面板50的一端临接距离传感器30，然后距离传感器30检测显示面板50的端部与距离传感器30之间的第一高度值H1，控制器70将所述第一高度值H1与基准高度值H2做差，若第一高度值H1与基准高度值H2的差值△H大于预设阈值H时，则证明所述显示面板50的端部的弯曲度过高，达不到使用的需求，进而所述检测装置100发出警示，提醒操作人员。如此，通过所述检测装置100，即可方便快捷的检测显示面板50的弯曲度是否达到使用需求，减少人工检测的工序，降低人工成本。
在本实施例中，在检测所述显示面板50的端部与距离传感器30之间的第一高度值H1的步骤后，还包括，检测所述显示面板50的中部平板区域的第二高度值，并将第二高度值发送至所述控制器70，所述控制器70将所述第二高度值记为基准高度值H2。
也即，不需要手动输入基准高度值H2，通过检测显示面板50的中部平板区域与距离传感器30之间第二高度值，将所述第二高度值记为基准高度值H2即可。
进一步地，在发出警示的步骤后，还包括：将所述显示面板50传送至复检部进行复检。也即，通过将弯曲程度超过预设阈值H的显示面板50复检，防止出现误检测的情况。
在本申请的一实施例中，在传输显示面板50的步骤前，还包括：通过触控显示器输入预设阈值H至一控制器70。也即，预先输入预设阈值H，所述预设阈值H的范围值为：0.5mm≤H≤1mm。所述预设阈值H的设定根据不同的显示面板50的尺寸进行设置，大规格的显示面板50其允许翘曲的高度值高一些，小规格的显示面板50其允许翘曲的高度值低一些。综合现有规格的显示面板50，其允许翘曲的高度值在0.5mm至1mm。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的申请构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
