Description

一种显示面板检测设备
本申请要求在2018年11月22日提交中国专利局、申请号为201811398263.7的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请属于显示面板技术领域，例如涉及一种面板检测设备。
背景技术
人工目视检查(Manual Visual Inspection，MVI)是显示面板检测的一种手段，相关MVI检测台通常为通过将水平放置的检测平台翻转获得检测角度，或者检测平台本就设置固定倾斜角度以便检测。但对于第一种方式，检测平台翻转克服平台重量，需要使用电机，对于一些中小尺寸面板的检测来讲，成本较高；对于第二种方式，检测平台具有固定倾斜角度，使得检测平台接料困难，对将面板移载于检测平台上的移载机构要求较高，不利于产线的自动化。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请提供一种即便于接料出料又没有高负载的显示面板的检测设备。
本申请提出以下技术方案：一种显示面板检测设备，显示面板检测设备包括：驱动底座；旋转台，设置于驱动底座上，且旋转台与水平面呈夹角α；以及载台，设置于旋转台上，且载台与旋转台呈夹角α。
在阅读并理解了附图和详细描述后，可以明白其他方面。
附图说明
图1为本申请一实施例侧面示意图；
图2为本申请一实施例立体示意图；
图3为本申请一实施例的驱动底座示意图。
其中：1、底座；11、倾斜支撑面；2、驱动机构；3、旋转台；4、载台；41、支撑台；42、支撑座；421、位置调节机构；5、压头组件；6、相机组件。
具体实施方式
下面结合附图及具体实施方式对本申请进行详细描述：
请参考图1至图3，图1为本申请一实施例侧面示意图；图2为本申请一实施例立体示意图；图3为本申请一实施例的驱动底座示意图。本申请的一实施例提供一种显示面板检测设备，包括驱动底座、旋转台3及载台4；旋转台3设置于驱动底座上，且旋转台3与水平面呈夹角α；载台4设置于旋转台3上，且载台4与旋转台3呈夹角α。载台4上放置待测面板，旋转台3驱动载台4旋转，由于载台4与旋转台3之间、旋转台3和水平面之间均存在夹角α，因此载台4在旋转过程中可在水平与倾斜之间切换，载台4水平时便于向载台4上放置待测面板或自载台4上卸载已检测完成的面板，旋转台3旋转180°后，则载台4与水平面的夹角为2α，载台4呈倾斜状态，便于人员对待测面板进行检测。该过程中只涉及旋转的动作，相比于相关技术中的翻转的动作的负载更低，且可同时实现面板水平上下料。
在一实施例中，显示面板检测设备具有第一工位和第二工位，旋转台3设置为驱动载台4旋转，使得载台4在第一工位和第二工位之间切换。
在一实施例中，第一工位和第二工位分别为上下料工位和检测工位。其中，载台4在上下料工位时是水平的，在检测工位时是倾斜的。当载台4位于上下料工位时，载台4是水平的，方便移栽机构将待测面板移栽至载台4上。当载台4位于检测工位时，载台4是倾斜的，适于进行人工目视检查。
在一实施例中，载台4与水平面的夹角可在0°和2×α之间切换。由于载台4与旋转台3之间有夹角α，旋转台3与水平面之间也有夹角α，当载台4随旋转台3旋转时，载台4与旋转台3之间的夹角α和旋转台3与水平面之间的夹角α会在相互抵消到相互叠加之间连续地变化，当两个夹角α相互抵消时，载台4与水平面的夹角为0°，当两个夹角α相互叠加时，载台4与水平面的夹角为2×α，因此，载台4与水平面的夹角可随着旋转台3的旋转而在0°和2×α之间切换。
在一实施例中，α可以设置为20°至25°之间，例如α可以设置为22.5°；但 不以此为限，α的大小可以根据实际检测需求进行设置。
在一实施例中，驱动底座包括底座1和驱动机构2，底座1具有倾斜支撑面11；驱动机构2设置于倾斜支撑面11上，驱动机构2驱动连接旋转台3。由驱动机构2驱动旋转台3进行旋转，载台4随着旋转台3旋转，如图1所示。
在另一实施例中，底座1设置于驱动机构2上，驱动机构2驱动连接底座1，旋转台3设置于支撑面11上。驱动机构2驱动底座1旋转，旋转台3和载台4随着底座1旋转，如图2所示。
在一实施例中，支撑面11与水平面呈夹角α。此时，支撑面11与旋转台3平行，设于二者之间的驱动机构2的上下两个端面平行支撑面11设置。
在一实施例中，载台4亦可以为偶数组，偶数组载台4两两对称地设置于所述旋转台3上；当然，偶数组载台4的位置也可以不对称设置，能满足水平上下料和倾斜检测即可。以载台4为两组为例，当其中一个载台4水平时，另一载台4倾斜，两个载台4分别位于上下料工位和检测工位，可分别对两块显示面板进行上下料和检测操作，比单独一个载台4的实施例中的工作效率更高；为进一步提高检测效率，载台4的数量可以设置为4组或更多。但不以此为限，载台4也可以为3组、5组等奇数组，实际操作中可以以检测需要具体设计载台4的数量。
在一实施例中，载台4包括支撑台41和支撑座42，支撑座42上设置有位置调节机构421，位置调节机构421设置为驱动支撑台41直线移动或旋转。待测面板置于支撑台41上，可随着支撑台41的直线移动或旋转改变位置，可设置为补正移载机构在将待测面板移载至支撑台41上时产生的位置误差，使待测面板在支撑台41上的位置始终准确，避免检测时因待测面板位置误差而产生检测误差；或者待测面板与压接机构的相对位置偏差时，对待测面板进行位置调整，以确保面板与压接机构精密压接实现检测信号的导通。
在一实施例中，显示面板检测设备还包括压头组件5，压头组件5设置于载台4上方，设置为与载台4上的待测面板压接导通，从而将外部检测信号输入待测面板，进而对点亮的面板进行检测。
在一实施例中，显示面板检测设备还包括相机组件6，相机组件6设置于载台4上方，设置为辅助压头组件5与载台4对位。载台4可根据相机组件6的位置信息调整自身位置，从而与压头组件5的压头精准对位。
