如图2至图4所示，在无边框手机中，触摸屏显示模组要比触摸屏10大，从而在触摸屏10安装后，触摸屏10四周与手机的中框50之间形成一条狭小的缝隙，需要通过外观色泽与中框50类似的柔性材料20进行填充。基于填充的柔性材料20，为了防止柔性材料20表面形成不规则的凹坑或纹路，本发明提出了触摸屏填缝工艺方法各实施例。需要说明的是，本发明实施例中的无边框手机是指手机左右两侧的边框较窄，当屏幕点亮时，从视觉上产生无边框的视效。
参照图1至图4，本发明实施例提供了一种触摸屏填缝工艺方法，在一实施例中，该触摸屏填缝工艺方法包括：
步骤S10，将触摸屏10四周的缝隙填充柔性材料20；
步骤S20，将触摸屏10四周填充好柔性材料20的手机固定在夹具30
上；
步骤S30，控制低表面能材料的压头40位于缝隙上方，且与缝隙内的柔性材料20贴合；
步骤S40，控制压头40与手机相对移动，以抹平缝隙内的柔性材料20。
本发明实施例提供的触摸屏填缝工艺方法主要应用在液晶显示设备中，本发明实施例以手机为例进行详细说明。具体地，该触摸屏填缝工艺方法主要是针对无边框手机的制造工艺。
本发明实施例中，在进行触摸屏填缝工艺时，首先将触摸屏10四周的缝隙填充柔性材料20；然后可以将多余的柔性材料20进行去除。在去除完多余的充柔性材料20后，需要对柔性材料20的表面进行抹平处理。具体地，可以通过一夹具30将手机进行固定，然后通过采用低表面能材料制成的压头40压接在中框50上，此时，压头40将与填充在触摸屏10四周缝隙内的柔性材料20相互贴合压持；最后控制压头40与手机之间发生相对移动，以对填充的柔性材料20进行平整。
具体地，对于压头40与手机之间相对移动的控制方式可以根据实际需要进行设置。例如在本实施例中，上述步骤S40包括：
保持手机不动，控制压头40沿缝隙形成的轨迹移动；或者，
保持压头40不动，控制夹具30带动手机移动，以使压头40沿缝隙形成的轨迹相对移动。
可以理解的是，在其他实施例中，还可以采用两种方式进行结合设计。具体地实现方式在此不做进一步地限定，只要能够保证压头40在手机上移动的轨迹为触摸屏10四周缝隙所形成的轨迹即可。
具体地，在本实施例中，在保持手机不动，控制压头40沿缝隙形成的轨迹移动的方式中，可以在手机上方设置轨道、与轨道匹配的滑块以及用于驱动滑块在轨道上运动的驱动电路。其中，该轨道为环形轨道，且与手
机的触摸屏10四周缝隙的形状和大小相对应，上述压头40直接或间接固定在滑块上，随着滑块沿轨道滑动，从使得压头40沿触摸屏10四周的缝隙移动。
在保持压头40不动，控制夹具30带动手机移动，以使压头40沿缝隙形成的轨迹相对移动的方式中，可以在手机的下方设置轨道、与轨道匹配的画面以及用于驱动滑块在轨道上运动的驱动电路，其中，该轨道为环形轨道，且与手机的触摸屏10四周缝隙的形状和大小相对应，上述夹具30直接或间接固定在滑块上，随着滑块沿轨道滑动，带动手机移动，从使得压头40沿触摸屏10四周的缝隙移动。
本发明实施例通过将触摸屏10四周的缝隙填充柔性材料20；将触摸屏10四周填充好柔性材料20的手机固定在夹具30上；控制低表面能材料的压头40位于缝隙上方，且与缝隙内的柔性材料20贴合；控制压头40与手机相对移动，以抹平缝隙内的柔性材料20。由于采用了低表面能材料的压头40对缝隙内的柔性材料20进行压平处理，从而提高了缝隙内的柔性材料20的平整度。
具体地，上述压头40相对于手机移动的方向和速度均可以根据实际需要进行设置，本实施例中，优选地，压头40相对于缝隙形成的轨迹按照逆时针或者顺时针方向循环移动。此外，压头40相对于缝隙形成的轨迹匀速移动。具体地，可以设定一个移动速度，并通过瞬时反馈调节，以达到速度恒定的效果。
本实施例中，控制压头40相对缝隙形成的轨迹按照逆时针或者顺时针方向循环移动，可以从整体保证缝隙内柔性材料20的平整度，防止柔性材料20在某一区域内堆积形成凸出部位或者缺少形成凹陷部。
进一步地，基于上述实施例，本实施例中，上述夹具30可以包括底座31和顶针32，其中底座31上设有安装定位手机的定位槽，顶针32位于定
位槽上方。上述将触摸屏10四周填充好柔性材料20的手机固定在夹具30上包括：
将触摸屏10四周填充好柔性材料20的手机部分容置于夹具30的底座31中定位槽内，使得触摸屏10顶部凸出定位槽设置；
控制夹具30的顶针32与触摸屏10顶部抵持，以与底座31配合夹持固定手机。
本实施例中，上述顶针32的数量和大小均可以根据实际需要进行设置。具体地，上述定位槽的形状和大小与手机相匹配；定位槽的深度根据实际情况可以进行设置，本实施例中，优选地，上述手机的中框50顶端位于定位槽外，在压头40压接中框50时，将不会与底座31相接触。安装时，可以将手机的背面置于定位槽内，并在放平后控制顶针32抵持手机的触摸屏10，从而通过顶针32和底座31配合相互夹持固定手机。
进一步地，为了提高柔性材料20表面的平整度，本实施例中，在压头40与手机相对移动的过程中，控制压头40压持柔性材料20的作用力保持恒定。
可以理解的是，对于控制压头40在相对移动的过程中，以恒定的压力压持柔性材料20，具体地实现方式可以根据实际需要进行设置。例如在一实施例中，可以恒压控制器控制压头40压持的作用力，在本实施例中，具体地，控制压头40压持柔性材料20的作用力保持恒定包括：
通过预设于压头40上方的压力检测装置60检测压头40的压力实时动态调整压头40压持柔性材料20的作用力。
在本实施例中，上述压力检测装置60设置在压头40上方，用于检测中框50及柔性材料20对于压头40的反作用力，根据检测的作用力的大小变化，实时动态调整压头40输出的压力大小，从而使得压头40压持柔性材料20的作用力保持恒定。具体地，可以设定压头40的压力大小，然后
根据压力检测装置60检测的压力大小的反馈，智能计算调整压头40压持柔性材料20的作用力。由于压头40的压力和相对移动速度保证恒定，不仅可以保证单个产品的外观统一性，还可以保证批量产品外观的统一性。
应当说明的是，上述压头40为低表面能材料，具体地，该低表面能材料的材质可以根据实际需要进行设置，上述柔性材料20的材质也可以根据实际需要进行设置，在本实施例中，优选地，该压头40与所述柔性材料20之间互不粘结。通过利用两者相互不粘接的特性，当压头40压持柔性材料20表面滑动的过程中，压头40与柔性材料20的结合面会形成少量水分，使柔性材料20表面发生软化现象，实现柔性材料20统一的外观效果。
具体地，在本实施例中，上述低表面能材料可以为硅胶；上述柔性材料20为胶水。可以理解的是，在其他实施例中低表面能材料和柔性材料20还可以其他类似的产品，在此不再一一赘述。
以上仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
本发明实施例通过将触摸屏四周的缝隙填充柔性材料；将触摸屏四周填充好柔性材料的手机固定在夹具上；控制低表面能材料的压头位于所述缝隙上方，且与所述缝隙内的柔性材料贴合；控制所述压头与手机相对移动，以抹平所述缝隙内的柔性材料。由于采用了低表面能材料的压头对缝隙内的柔性材料进行压平处理，从而提高了缝隙内的柔性材料的平整度。
