其中，夹具组件40设置在腔体10内。夹具组件40用于夹持所述柔性显示面板，所述夹具组件40包括旋转驱动机构403，并在柔性显示面板以预设速度朝向所述曲面盖板贴合时，所述旋转驱动机构控制所述夹具组件旋转直至所述柔性显示面板与所述曲面盖板完全贴合后与所述柔性显示面板分离。需要说明的是，该预设速度可以根据本领域技术人员的需要进行设置。
也即，可通过旋转驱动机构403，抵紧块组件30上升压合时，夹具组件40同步旋转，夹具组件40可持续固定柔性显示面板，防止柔性显示面板的边缘与曲面盖板的边缘在抵紧块组件30过早接触，可以避免曲面盖板与柔性显示面板之间产生气泡，进而可以提高贴合质量。
具体的，夹具组件40包括第一夹具401、第二夹具402以及旋转驱动机构403。第一夹具401夹持在柔性显示面板的第一侧，第二夹具402夹持在柔性显示面板的第二侧，第一侧与第二侧相对。旋转驱动机构403与第一夹具401以及第二夹具402连接，旋转驱动机构403用于控制第一夹具401以及第二夹具402旋转。旋转驱动机构403可以采用电机实现，例如步进电机。在一些实施例中，第一夹具401的夹持面与第二夹具402的夹持面均设置有防黏层。
在一些实施例中，夹具组件40可以采现有技术中的结构来实现其旋转及脱离，例如三轴驱动机构结合旋转电机。
本申请实施例提供的贴合装置，通过给夹具组件增加旋转功能，抵紧块组件上升压合时，夹具组件同步旋转，夹具组件可持续固定柔性显示面板，防止柔性显示面板的边缘与曲面盖板的边缘在抵紧块组件过早接触，可以避免曲面盖板与柔性显示面板之间产生气泡，进而可以提高贴合质量。
请参照图2，图2为本申请实施例提供的贴合方法的流程示意图。本申请实施例提供的贴合方法采用以上所述的贴合装置进行贴合。该贴合方法包括以下步骤：
S201、将柔性显示面板弯曲预设弧度，并通过夹具组件夹持所述柔性显示面板；
S202、对腔体进行抽真空处理，并将所述柔性显示面板上升至预设贴合位置；
S203、控制抵紧块组件将所述柔性显示面板以预设上升速度朝向所述曲面盖板贴合，并控制所述夹具组件以预设旋转速度旋转直至所述柔性显示面板与所述曲面盖板完全贴合后与所述显示面板分离。
具体的，请同时参照图3-图6，图3为本申请实施例提供的柔性显示面板的曲面盖板贴合方法的第一种操作场景图；图4为本申请实施例提供的柔性显示面板的曲面盖板贴合方法的第二种操作场景图；图5为本申请实施例提供的柔性显示面板的曲面盖板贴合方法的第三种操作场景图；图6为本申请实施例提供的柔性显示面板的曲面盖板贴合方法的第四种操作场景图。
在S201中，将柔性显示面板200弯曲预设弧度，将贴合装置1000的第一夹具401和第二夹具402分别夹在柔性显示面板200的两未被弯曲的相对的侧边上，第一夹具401和第二夹具402可沿着侧边旋转。操作时，先将贴合装置1000的第一部分101打开，其中，该预设弧度曲率小于该贴合装置1000的抵紧块的的曲率。
在S202中，将弯曲后的柔性显示面板200放置在贴合装置1000的抵紧块301上。其中，将柔性显示面板200设置在抵紧块301上后，将第一部分101与第二部分102闭合实现密封。对贴合装置1000的腔体10进行抽真空，并控制抵紧块组件30将柔性显示面板200朝向贴合装置1000的承载台20的凹槽201的方向移动，以将柔性显示面板200上升至预设贴合位置。
在S203中，控制抵紧块组件30以预设上升速度顶升柔性显示面板200，并控制夹具组件40自第一夹具401和第二夹具402的外侧朝向远离凹槽201的方向旋转，在柔性显示面板200完全进入凹后，第一夹具401和第二夹具402脱离柔性显示面板200。
其中，第一夹具401和第二夹具402可以持续固定住柔性显示面板200与曲面盖板100不提前接触，光学黏胶层不会拉胶。柔性显示面板200的上表面贴附一层光学黏胶层。其中，第一夹具401的夹持面和第二夹具402的夹持面均设置有防粘层，以避免第一夹具401以及第二夹具402与光学黏胶层粘接。
其中，第一夹具401和第二夹具402的预设旋转速度与抵紧块301的预设上升速度可通过仿真计算相匹配，通过仿真模拟计算得到具体的值，在贴合操作末端第一夹具401和第二夹具402快速后退以与柔性显示面板200分离，抵紧块301持续向上压合并保压。由于有些显示面板的边缘不与曲面盖板提前接触粘住，气泡通过抵紧块挤压有效排出。
本申请实施例提供的贴合装置及柔性显示面板的曲面盖板贴合方法，通过给夹具增加旋转功能，抵紧块组件上升压合时，夹具同步旋转，夹具可持续固定柔性显示面板，防止柔性显示面板的边缘与曲面盖板的边缘在抵紧块组件过早接触，可以避免曲面盖板与柔性显示面板之间产生气泡，可以提高贴合质量。
虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
