另外，下面结合附图描述的本发明的实施方式是示例性的，仅用于解释本发明的实施方式，而不能理解为对本发明的限制。
请参阅图1和图2，本发明实施方式提供的膜材折弯设备100，包括折弯轴10、固定装置20和夹持装置30。固定装置20位于折弯轴10一侧，用于固定待折弯膜材40一端。夹持装置30位于折弯轴10另一侧，用于夹持待折弯膜材40的另一端。夹持装置30包括基板32、夹持件34和弹性组件36。基板32可相对于折弯轴10转动。夹持件34滑动设置在基板32上。弹性组件36连接基板32和夹持件34，夹持件34通过弹性组件36滑动设置在基板32上，夹持件34用于夹持待折弯膜材40，并带动待折弯膜材40绕折弯轴10转动，以将待折弯膜材40折弯在折弯轴10上。
本发明实施方式的膜材折弯设备100通过带动待折弯膜材40绕折弯轴10表面弯曲以测试待折弯膜材40的折弯能力。由于夹持件34通过弹性组件36可滑动设置在基板32上，因此，弹性组件36在折弯过程中保持对待折弯膜材40施加弹性拉力，一方面可以保证待折弯膜材40紧绕折弯轴10，保证了折弯精度，另一方面，弹性连接也可以避免膜材扯断或损坏等情况。
具体地，折弯轴10呈圆柱状，表面光滑。
夹持装置30带动待折弯膜材40绕折弯轴10转动过程中，待折弯膜材40保持和折弯轴10的紧密接触，折弯轴10表面光滑可以防止刮伤待折弯膜材40。
折弯轴10一般采用不锈钢制成。
不锈钢成本低，制造简单，能降低膜材折弯的加工成本，同时不锈钢有较好的硬度和耐腐蚀性，使用寿命较长。
基板32通过螺母或焊接固定。
如此可以避免在折弯过程中基板32可能会发生松动，向靠近折弯轴10或远离折弯轴10的方向发生位移的情况，影响待折弯膜材40的弯曲精度。
夹持件34和折弯轴10保持距离。
如此避免了在夹持件34旋转过程中和折弯轴10发生碰撞，导致待折弯膜材40改变位置，影响折弯精度的情况。
在本实施方式中，膜材折弯设备100进一步包括主平台50，主平台50包括转盘52，折弯轴10与转盘52同轴设置，夹持装置30偏离转盘52中心设置在转盘52上。
本发明实施方式中，折弯轴10和转盘52同轴，如此，折弯轴10不随转盘52一起旋转，待折弯膜材40能稳定地绕着折弯轴10进行弯曲，保证了待折弯膜材40的折弯效果。
夹持装置30设置在转盘52的偏心位置，如此，夹持装置30能带动待折弯膜材40的一端绕折弯轴10旋转。
进一步地，夹持装置30可设置在靠近转盘52中心的位置。
如此，不但保证了折弯效果，还能减小转盘52的面积，进而使膜材折弯设备100的结构变得更加紧凑，从而减少膜材折弯设备100制造材料的消耗，节省能源。
在本实施方式中，膜材折弯设备100还包括与主平台50分立设置的副平台60，折弯轴10设置在副平台60上。
如此，进一步保证折弯轴10不跟随转盘52旋转，也不会和夹持装置30发生碰撞，使待折弯膜材40能稳定地绕折弯轴10进行弯曲，进一步提高了待折弯膜材40的折弯效果。
具体地，副平台60与主平台50间隔设置，间隔距离为3厘米-10厘米。
如此，主平台50和副平台60上的部件运行时不会相互影响，同时，整个膜材折弯设备100显得较为紧凑和一体化，减少占用空间，也便于实现大规模专业化生产。
进一步地，副平台60呈平面板状结构，一般采用钢制作。
如此，副平台60能为设置在副平台60上的部件提供稳定支撑。
副平台60底部还能设置支脚。
如此能防止有水或油污进入副平台60上，对副平台60上部件的工作造成影响或者锈蚀副平台60上的部件。
在某些实施方式中，副平台60包括底座62及设置在底座62上的固定架622，折弯轴10可拆卸地设置在固定架622上。
如此，可根据待折弯膜材40不同的折弯需求，更换不同直径的折弯轴10，操作简单方便，大大提升了膜材折弯设备100的效益。
在某些实施方式中，固定架622上包括设置在底座62上且相互平行的安装板624，安装板624上形成有安装孔6242；
折弯轴10包括轴体及位于轴体两端且与安装孔6242匹配的安装片626，折弯轴10通过安装片626和安装孔6242的配合关系安装在所固定架622上。
本发明实施方式中，相互平行的安装板624保证了折弯轴10能垂直于转盘52，进而保证了待折弯膜材40绕折弯轴10折弯的效果；安装片626可拆卸，安装片626包括配合孔，多个安装片626的直径固定，配合孔的直径不同，如此，更换不同直径的折弯轴10，可更换有与折弯轴10直径一致的配合孔的安装片626，折弯轴10两端插入安装片626的配合孔中，安装片626再固定到安装板624上的安装孔6242上，从而可使用不同直径的折弯轴10来折弯待折弯膜材40。
具体地，安装片626和折弯轴10可通过螺纹连接的方式固定。
如此，更换不同的安装片626和折弯轴10时，操作方便快捷。
进一步地，安装片626和安装板624也可通过螺纹连接的方式。
如此，安装片626易于更换，操作简单快速。
在某些实施方式中，膜材折弯设备100包括与主平台50分立设置的副平台60，固定装置20设置在副平台60上。
折弯待折弯膜材40的过程中，膜材对固定装置20施加较大拉力，将固定装置20设置在副平台60上，固定装置20更稳定，膜材也就能更稳定地固定在固定装置20上，避免了固定装置20松动导致膜材一端在折弯过程中发生位移从而影响膜材的折弯精度的情况。
具体地，固定装置20包括连接部6214，连接部6214上开设有通孔，副平台60的底座62上开设有螺孔，紧固件穿过通孔进入螺孔，将固定装置20固定在底座62上。
如此，固定装置20能更稳定地设置于底座62上。
在某些实施方式中，副平台60包括底座62、形成于底座62上的第一轨道628和滑动设置在第一轨道628上的固定板621，第一轨道628的导向与折弯轴10垂直，固定装置20设置在固定板621上，固定装置20形成有用夹设待折弯膜材40的夹缝22，夹缝22与折弯轴10平行。
本发明实施方式中，待折弯膜材40较短时，固定板621可在第一轨道628上滑动，靠近折弯轴10，对待折弯膜材40进行稳定的固定；待折弯膜材40较长时，固定板621可在第一轨道628上滑动，远离折弯轴10，方便固定装置20对待折弯膜材40进行固定；夹缝22平行于折弯轴10，使待折弯膜材40能保持和折弯轴10紧密接触，避免了在夹持装置30带动待折弯膜材40的另一端旋转的过程中，待折弯膜材40与折弯轴10脱离接触从而影响待折弯膜材40的折弯精度的情况。
具体地，第一轨道628的长度可设置得较长。
如此，折弯不同长度的待折弯膜材40时，固定板621可在第一轨道628上滑动调整距离折弯轴10的距离，以使固定装置20能对待折弯膜材40进行稳定的固定。
两个夹板形成夹缝22，待折弯膜材40一端设置在夹缝22中，再通过紧固件将两个夹板固定在一起，从而固定住待折弯膜材40的一端。
如此结构简单，易于实现。
当然，还能在夹缝22附近设置线圈和磁场，在线圈中通电。
线圈通电结合磁场产生电磁感应，使夹缝22产生对待折弯膜材40的吸力，从而将待折弯膜材40固定在固定装置20上。
在某些实施方式中，固定板621形成有第二轨道6212，第二轨道6212的导向垂直于折弯轴10，固定装置20滑动设置在第二轨道6212上。
如此，当更换不同直径的折弯轴10后，夹缝22可随固定装置20通过第二轨道6212上下调整位置，使待折弯膜材40保持与不同直径的折弯轴10的紧密接触。
具体地，第二轨道6212的长度可设置得较长。
如此，固定板621的上下调整距离较长，固定板621能配合更多的折弯轴10对待折弯膜材40进行折弯操作。
在某些实施方式中，夹持件34形成有夹持缝隙342，夹持缝隙342平行于折弯轴10。
如此，使待折弯膜材40能保持和折弯轴10紧密接触，避免了在夹持装置30带动待折弯膜材40的另一端旋转的过程中，待折弯膜材40与折弯轴10脱离接触从而影响待折弯膜材40的折弯精度的情况。
在某些实施方式中，夹持件34包括螺旋夹紧、偏心夹紧或联动夹紧。
具体地，螺旋夹持件34是指通过螺旋副、压板、垫片和螺钉等元件的配合对待折弯膜材40实施夹紧的部件。螺旋夹持件34结构简单，夹紧行程大，且自锁性能好，增力比大；
具体地，偏心夹持件34是指用偏心件直接或间接夹紧对待折弯膜材40的机构。偏心夹持件34包括圆偏心和曲线偏心。圆偏心夹持件具有结构简单、操作方便、夹紧迅速等优点；
具体地，联动夹持件34是指利用一个原始作用力实现对对待折弯膜材40的多点、多向同时夹紧的机构。联动夹持件34对待折弯膜材40的夹紧比较稳定。
在某些实施方式中，弹性组件36包括可拆卸地连接基板32与夹持件34的弹性件。
例如：弹性件可以是弹簧。
如此，折弯延展度较大的待折弯膜材40时，可选用弹性较小的弹性件；折弯延展度较小的待折弯膜材40时，可选用弹性较大的弹性件，避免了弹性件将待折弯膜材40拉断的情况。同时，弹性组件36还能采用不同数量的弹性件，折弯延展度较大的待折弯膜材40时，可选用较少数量的弹性件；折弯延展度较小的待折弯膜材40时，可选用较多数量的弹性件，以保证对待折弯膜材40的拉紧且不损坏待折弯膜材40。
具体地，基板32上可设置有挂钩，挂钩穿过弹性组件36将弹性组件36固定在基板32上。
如此，更换不同弹性的弹性件或不同数量的弹性件时，简单方便。
在某些实施方式中，基板32包括凸出部324，弹性件一端固定在凸出部324上，另一端固定连接夹持件34，通过弹性件限制夹持件34的移动距离，即限制夹持件34向凸出部324方向的运动。基板32上设置有限位块322，限位块322位于夹持件34和凸出部324之间，限位块322限制夹持件34向凸出部324方向运动。
如此，在弹性件弹性过大的情况下限位块322可限制弹性件带动待折弯膜材40过度向凸出部324方向运动从而避免待折弯膜材40被扯断，有效保证了待折弯膜材40的安全。
进一步地，限位块322可设置成滑动式。
如此，可根据不同的弹性件自由调整限位块322的位置，进一步保证待折弯膜材40不被弹性件扯断。
所述待折弯膜材40可以为柔性显示屏，膜材折弯设备100可以用于测试该柔性显示屏的折弯能力，例如折弯角度、折弯次数。
