具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行描述。
本发明实施例的技术方案可以应用于所有具有显示屏的移动终端，例如移动终端可以是具有显示器的移动电话、平板个人电脑(Tablet Personal Computer)、媒体播放器、智能电视、笔记本电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、个人计算机(Personal Computer)、移动上网装置(Mobile Internet Device)或智能手表等可穿戴式设备(Wearable Device)等，本发明实施例对此不作限定。
图1示出了移动终端的显示屏与壳体的示意性结构图，如图1所示，具有显示屏的移动终端包括显示屏110和壳体120，该壳体120的内表面可以包括底面121和四个侧面(图1中示出了侧面122)，该底面与每个侧面之间都存在相同的夹角，现有的移动终端组装方法为通过在壳体120的内表面上点胶后，将该显示屏110粘结到该壳体120的内部。
由于壳体内表面比较光滑，因此，直接通过点胶的方式将显示屏与壳体粘结在一起，粘结强度不理想，容易出现显示屏脱落的现象。
图2示出了本发明实施例的壳体与显示屏的粘结方法100的示意性流程图。
S110，将包括多个通孔的聚合物层粘结在该壳体的内表面上。
S120，对粘结在该壳体内表面上的该聚合物层进行点胶。
S130，对点胶后的该聚合物层与该显示屏进行粘结。
应理解，通孔可以为贯穿该聚合物层上下表面的孔。
本发明实施例的壳体与显示屏的粘结方法，由于粘结在壳体内表面的聚合物层上包括多个通孔，因此，在对该聚合物层点胶时，胶水可以灌进聚合物层上的通孔与壳体粘结后形成的凹槽中，这样以来，在凹槽中可以容纳更多胶水，胶水能够与凹槽的槽壁贴合，增加了胶水的比表面积，从而能够增加该聚合物层和显示屏的粘结强度。
应理解，本发明实施例中的聚合物层可以为高聚物，能够牢固固化在壳体内表面，另外，该聚合物层的表面形态较复杂，能够增加该聚合物层的表 面粗糙度，从而增加与显示屏之间的粘结强度。
此外，本发明实施例中的聚合物层的材质还具有弹性和刚性，能够起到缓冲的作用，在终端设备从高处跌落时，能够起到保护显示屏的作用。
下面将结合图3至图12对本方法实施例的壳体与显示屏的粘结方法100进行说明，但是本发明实施例并不限于此。
图3示出了本发明实施例的聚合物层200的示意性结构图，其中，图3中的(a)中示出了本发明实施例的聚合物层200的平面图，图3中的(b)中示出了本发明实施例的聚合物层200的侧视图。
如图3中的(a)所示，该聚合物层200可以包括多个通孔(图中示出了通孔210)，该多个通孔可以为不规则排布，也可以为均匀排布，该聚合物层例如可以为网状聚合物层，本发明实施例对此不作限定。
可选地，该聚合物层可以为弹性和刚性很强的材质，例如可以为尼龙之类的材质。另外由于该聚合物层可以为网状的，例如可以为渔网状聚合物层，接触面表面形貌复杂，可以增加粘结面的粗糙度。
可选地，该聚合物层上的通孔的孔径可以为0.01mm～0.3mm。
本发明实施例的壳体与显示屏的粘结方法，能够满足未来移动终端更窄的显示屏边框，以及更薄的机身等需求中粘胶面积更小的设计需求。同时避免孔径过小与壳体表面形态特征过于类似，起不到增加壳体表面粗糙度的作用的情况。
图4示出了本发明实施例的通孔的表面形状示意图，如图4所示，该网状聚合物层上的通孔的表面形状可以为图4中的(a)中所示的正方形、图4中的(b)中所示的三角形、图4中的(c)中所示的圆形或者图4中的(d)中所示的平行四边形，或者根据不同形状点胶台的形状确定的通孔表面形状，但本发明实施例并不限于此。
本发明实施例的壳体与显示屏的粘结方法，通过控制该聚合物层上的通孔的表面形状，能够满足各种点胶场景下不同点胶台形状的设计需求。
可选地，本发明实施例的壳体与显示屏的粘结方法，可以通过紫外固化或胶水粘结等方式将所述聚合物层粘结在所述壳体的内表面，本发明实施例对此不作限定。
可选地，该壳体的内表面可以包括第一内表面和第二内表面，该第一内表面和该第二内表面之间存在夹角，其中，该第一内表面可以为该壳体内表 面的底面，该第二内表面可以为该壳体内表面的侧面。
可选地，该壳体可以包括多个侧面，该多个侧面中的每个侧面均与该底面之间存在夹角，本发明实施例对此不作限定。
具体而言，在S110中，可以将该聚合物层进行弯折，并将弯折后的该聚合物层粘结在该第一内表面和该第二内表面上。
本发明提供的壳体与显示屏的粘结方法，通过透明压合模具将弯折后的聚合物层与涂覆固化胶的第一内表面和第二内表面紧密贴合，并通过对该压合模具进行紫外光照射，将该聚合物层固化在所述壳体上，能够增加该壳体与该聚合物之间的粘结强度。
作为一个可选实施例，图5示出了本发明实施例的聚合物层与壳体的粘结方法示意图，如图5所示，可以通过在该壳体300的内表面上涂覆固化胶，将如图3所示的聚合物层200覆盖在该固化胶上，将透明压合模具400置于该聚合物层上，对该固化胶和该聚合物层进行压合处理，通过置于该聚合物层上的该透明压合模具，对该壳体上的该聚合物层进行紫外光500照射，对该聚合物层进行紫外固化处理，从而使得该具有通孔的聚合物层固化在该壳体的内表面。
应理解，由于该透明压合模具400具有一定的重量，因此，将该透明压合模具放置于覆盖在固化胶上的聚合物层上，能够使得该聚合物层与固化胶充分接触，紧密压合。另外，由于该透明压合模具400为透明的，因此，可以在该透明压合模具对该聚合物层进行压合的同时，对该透明压合模具进行紫外光照射，能够更进一步增加该聚合物层与该壳体内表面的粘结强度。
还应理解，由于该聚合物层可弯曲，因此，在将该聚合物层覆盖涂覆固化胶的壳体内表面时，可以完全贴合该壳体的内表面包括的底面和侧面。
可选地，该聚合物层可以只覆盖在该壳体300内表面的底面310，或者侧面320，或者可以同时覆盖该壳体内表面的底面和侧面，本发明实施例对此不作限定。
图6示出了本发明实施例的点胶方法示意图，如图6所示，点胶时可以在固化在壳体内表面的聚合物层上进行点胶，由于粘结在壳体内表面的聚合物层上包括多个通孔，因此，在对该聚合物层点胶时，胶水可以灌进聚合物层上的通孔与壳体粘结后形成的凹槽中(例如图6中通孔210与壳体之间形成的凹槽)，这样以来，在凹槽中可以容纳更多胶水，胶水能够与凹槽的槽 壁贴合，增加了胶水的比表面积，从而能够增加该聚合物层和显示屏的粘结强度。
可选地，可以在壳体内表面的底面和侧面的夹角处的聚合物层上进行点胶，将显示屏覆盖在点胶后的聚合物层上压合后，可以使得胶水覆盖整个聚合物层，以防胶水过多溢出。
图7示出了本发明实施例的壳体与显示屏的粘结方法示意图。如图7所示，在固化在壳体300内表面的聚合物层200上进行点胶，并将显示屏600放置于壳体300的内部，对显示屏600与壳体300进行粘结。
应理解，图7中仅以壳体的局部示意图(一个侧面与底面)为例进行示意性说明壳体与显示屏的粘结方法，但本发明实施例不限于此。
上面结合图1至图7描述了本发明实施例的壳体和显示屏的粘结方法，下面将结合图8至图12详细介绍本发明实施例的网状聚合物层的制备方法。
作为一个可选实施例，图8示出了本发明实施例的网状聚合物层的制备方法示意图。如图8所示，可以通过以下方式制备该聚合物层包括：在基板710上涂覆固化胶，并进行紫外固化处理，形成平板状的聚合物层720，在该平板状的聚合物层720上涂覆保护胶，并进行紫外固化处理，形成保护胶层730，其中，该平板状的聚合物层720层用于经过下述处理得到待制备的网状聚合物层，该保护胶层730用于形成制备网状聚合物层的图形层。
图9示出了本发明实施例的另一聚合物层的制备方法示意图。如图9所示，激光束750通光掩膜740在如图8中的保护胶层730上进行曝光，形成多个曝光区域(图9中示出了曝光区域731)，使用溶剂除去所述保护胶层730上除该多个曝光区域以外区域的保护胶，得到如图10中所示的网状的保护胶层732。
图11示出了本发明实施例的光掩膜的示意图。如图11中所示，可以根据光掩膜740对该保护胶层进行曝光，其中，该光掩膜上包括多个透光孔(图11中示出了透光孔741)，光束通过该多个透光孔在该保护胶层上形成与该多个透光孔对应的多个曝光区域，使用溶剂将该保护胶层上除该多个曝光区域以外区域的保护胶，形成如图10中所示的网状保护胶层732。
可选地，本发明实施例还可以使用激光在保护胶层上直接进行图形绘制，并通过溶剂除去图形区域外的保护胶，得到网状保护胶层，但本发明实施例并不限于此。
图12示出了本发明实施例又一聚合物层的制备方法示意图，如图12所示，根据该网状保护胶层732上的网状图形在该平板状聚合物层上进行刻蚀，除去该平板状聚合物层上没有保护胶层覆盖的区域的聚合物，只留下有保护胶覆盖的区域(如图12中示出的区域721)的聚合物，最后使用溶剂除去保护胶层的保护胶，得到具有与网状的保护胶层相同结构的网状聚合物层。
可选地，通过调节制备本发明实施例中的聚合物层的材质和原料成分，可以制备出具有刚性和弹性的聚合物层，例如可以为尼龙类的高聚物，能够增加聚合物层与其他表面进行粘结的粘结强度，但本发明实施例对此不作限定。
上面结合图1至图12描述了本发明实施例的壳体与显示屏之间的粘接方法，下面将结合图13和图14描述本发明实施例的壳体组件和移动终端。
图13示出了本发明实施例的壳体组件，该壳体组件包括壳体300和聚合物层200，该聚合物层200包括多个通孔，且该聚合物层可以通过紫外结固化的方式固化在该壳体的内表面上。
可选地，该壳体的内表面可以包括第一内表面(如图13中的底面310)和第二内表面(如图13中的侧面320)，该第一内表面和该第二内表面之间存在夹角，该聚合物层经弯折后分别与该第一内表面和该第二内表面粘结在一起。
由于本发明实施例的壳体组件中的聚合物层上包括多个通孔，因此，在对该聚合物层点胶时，胶水可以灌进聚合物层上的通孔与壳体粘结后形成的凹槽中，这样以来，在凹槽中可以容纳更多胶水，胶水能够与凹槽的槽壁贴合，增加了胶水的比表面积，从而能够增加该聚合物层和显示屏的粘结强度。
可选地，本发明实施例的壳体组件中的聚合物层可以为网状聚合物层，该网状聚合物层固化在该壳体表面能够增加壳体表面的粗糙度，从而增加与显示屏之间的粘结强度。
另外，本发明实施例的壳体组件中的聚合物层的材质还具有弹性和刚性，能够起到缓冲的作用，在终端设备从高处跌落时，能够起到保护显示屏的作用。
图14示出了本发明实施例的移动终端局部侧视图，该移动终端包括显示屏600和壳体300，该显示屏600和该壳体300根据如图1至图12中描述的粘结方法，通过包括多个通孔的聚合物层200粘结在一起，为避免重复， 此处不再赘述。
