需要说明的是，在本申请实施例中，虽然图1和图2中的第一弯折部11和第二弯折部12的结构相同，但是这只是最优的方式，还可以存在仅有第一弯折部11的存在情况，另一侧只需要能固定待测试面板即可，另外，下方实施例存在同样的情况，不再一一赘述。

其中，第二载台121用于承载待测试面板，其待测试面板的整个形状应该是中间段为曲线，中间段的两侧为直线，因此，第一载台111还可用于对待测试面板进行测试时，以支撑待测试面板弯折时的两侧直线段的一侧部位。
需要说明的是，在本申请实施例中，虽然图1和图2中的第一弯折部11和第二弯折部12的结构相同，但是这只是最优的方式，还可以存在仅有第二弯折部12的存在情况，另一侧只需要能固定待测试面板即可，另外，下方实施例存在同样的情况，不再一一赘述。

其中，第一载台111和第二载台121用于共同承载待测试面板，其待测试面板的整个形状应该是中间段为曲线，中间段的两侧为直线，因此，第一载台111和第二载台121还可用于对待测试面板进行测试时，以分别支撑待测试面板弯折时的两侧直线段的部位。
本申请实施例中，所述第一载台111与所述第一机械臂114转动连接，所述第一驱动装置115包括第一驱动部116和第二驱动部126，所述第一驱动部116的一端连接于所述底座部13，所述第一驱动部116的另一端转动连接于所述第一机械臂114，以驱动所述第一机械臂114转动，所述第二驱动部126的一端连接于所述第一机械臂114，所述第二驱动部126的另一端转动连接于所述第一载台111，以驱动所述第一载台111转动；和/或，

其中，第一驱动装置115与第二驱动装置125可以都是主动型驱动，且第一驱动装置115与第二驱动装置125是可以协同工作的，如图1、2，在实际测试过程中，随着待测试面板的弯曲率逐渐变大时，其待测面板的两端可能会出现向上翘的可能，且存在面板与第一载台111或第二载台121相互摩擦的可能，因此，为了避免这种情况的发生，在实际测试过程中，随着待测试面板的弯曲率逐渐变大时，应该调节第一载台111与第一机械臂114之间的夹角，为此，本申请通过第二驱动装置125中的第三驱动部117收缩以主动减小第一载台111与第一机械臂114之间的夹角，从而避免上述问题的产生。

其中，当压力传感器21出现问题时，或者预先设置的测试值存在问题时，可以通过视觉传感器以及主控器控制弯折机构10弯折角度，避免上述问题存在，例如，待测试面板的弯曲率会有一个最大限定值，由此，可以给主控器预先输入该弯曲率的最大限定值，当测试过程中，检测到待测试面板的弯曲率接近最大限定值，则主动停止测试。
需要说明的是，上述方案只是一个具体的实施方式，具体的，还可以采用角度传感器，且该角度传感器可以用于检测弯折机构10中存在角度改变的结构，例如，检测第一载台111和第一机械臂114之间的夹角，又或者检测第一机械臂114于底座之间的夹角。

其中，第一支撑座118还可包括第一支撑板1181和第一支撑层1182，第二支撑座119还可包括第二支撑板1191和第二支撑层1192。
其中，随着用户的需求多样化以及显示面板的场景多样化，显示面板的尺寸要求也是多样化，在传统的测试过程中，其面板弯折测试装置也是随着某一尺寸的面板产量的完成后不再被重复利用，因此，本申请为解决该问题，以调整面板测试装置的结构，以使得同一面板弯折测试装置可以适应多种尺寸面板，提高利用率，节约资源。进一步的，本申请通过将第一弯折部11与所述第一支撑座118转动连接，所述第一支撑座118与所述载具14滑动连接，以调节所述第一弯折部11与所述第二弯折部12之间的间距。从而可以根据不同长度的待测试面板进行调节。
其中，载具14与弯折机构10可以是一体的，也可以不是一体的，当载具14与弯折机构10可以是一体时，其载具14与底座部13之间的滑动连接方式可以是卡合方式，并且可分为多个档位，当底座部13处于载具14的档位时，是可以进行固定的，具体固定方式不作限定，当载具14与弯折机构10不是一体时，其弯折机构10与载具14之间为可拆卸结构，为了确保面板弯折测试装置在测试过程中，弯折机构10内部不产生相对滑动，可以在弯折机构10与载具14之间设置一防护层，或者多个卡合结构，从而满足弯折机构10的调节功能，同时避免弯折机构10内部不产生相对滑动。载具14还包括至少两对滑轨141。
