Description

屏幕的安装方法、终端的组装方法及终端 技术领域
本发明涉及屏幕的安装领域，具体而言，涉及一种屏幕的安装方法、终端的组装方法及终端。
背景技术
现有触摸屏(TP)的固定方式为底部双面胶或点胶固定，而为了使得TP能够顺利地组装在壳体上，必须要在壳体与触摸屏预留组装缝隙，该缝隙一方面容易积灰，另一方面，降低了产品的密封性能，从而容易损坏安装在壳体内、触摸屏下方的电子元件。
因此，如何设计出一种新的可将屏幕无缝安装在壳体上的安装方法成为目前亟待解决的问题。
发明内容
本发明正是基于上述问题，提出了一种新的可将屏幕无缝安装在金属壳上的安装方法。
有鉴于此，本发明的一方面提出了一种屏幕的安装方法，包括：将屏幕安装在金属壳内的预设位置上；利用冷挤压模具挤压所述金属壳的侧壁，使所述金属壳的侧壁向所述金属壳内变形，并与所述金属壳内的所述屏幕无缝贴合。
在该技术方案中，在将屏幕安装在金属壳内的预设位置上后，通过挤压金属壳，可使金属壳向靠近屏幕的方向产生塑性变形，从而该塑性变形可填补屏幕与金属壳之间的缝隙并使金属壳与屏幕的侧壁紧密贴合，进而在将屏幕装配到金属壳上后，便能够实现屏幕与金属壳之间的无缝安装。同时，该挤压过程采用冷挤压模具进行冷挤压，即不加热的情况下挤压，从而可防止金属壳内的电子元件受热损坏的情况发生。具体地，预设位置为屏幕在金属壳内的待安装位置，比如对于手机等移动终端而言，金属壳 的一端面为敞口，屏幕一般镶嵌在敞口处，因此，预设位置便为该敞口处。同时，在具体挤压金属壳时，可预先设置一个专用的冷挤压模具，并在该冷挤压模具上加工出与壳体的形状、大小一致的模腔，以便该冷挤压模具可刚好套设在金属壳外，从而便可利用该冷挤压模具同时挤压金属壳的外侧，以实现金属壳的一次挤压成型，进而可提高屏幕的安装效率。
在上述技术方案中，优选地，在所述将屏幕安装在金属壳内的预设位置上之前，还包括：在所述屏幕的四周加工出倒角。
在该技术方案中，倒角可加大金属壳的变形量，从而在金属壳变形后，金属壳上能够对应地形成与倒角相适应的斜面，该斜面能够进一步阻止屏幕从金属壳内滑出，从而能够提高屏幕安装的可靠性。
在上述技术方案中，优选地，所述倒角的角度大于0°小于90°。
在该技术方案中，倒角的角度优选为30°至60°。
在上述技术方案中，优选地，所述将屏幕安装在金属壳内的预设位置上包括：将所述屏幕胶合在所述预设位置上或利用所述金属壳内的限位件将所述屏幕限位在所述预设位置上。
在该技术方案中，可通过底部双面胶或点胶的固定方式将屏幕胶合安装在金属壳的预设位置上，或者还可通过在金属壳的内壁上设置支撑块等限位件的方式将屏幕限位安装在金属壳的预设位置上，通过上述方式，能够对屏幕起到初步定位的作用，从而可防止在冷挤压过程中，屏幕出现挪动或倾斜的现象，从而可确保挤压安装后，屏幕依旧能够精准的安装在预设位置上。
在上述技术方案中，优选地，所述金属壳的侧壁包括两个相对设置的第一侧壁和第二侧壁，其中，所述第一侧壁和所述第二侧壁向所述金属壳内变形后，挤压所述屏幕并与所述屏幕无缝贴合。
在该技术方案中，金属壳的侧壁包括两个相对设置的第一侧壁和第二侧壁，从而从金属壳的两边同时向内挤压第一侧壁和第二侧壁时，第一侧壁和第二侧壁便可从屏幕的两边向内变形并夹紧屏幕，从而即可实现屏幕与金属壳之间的无缝贴合，又可实现金属壳的侧壁对屏幕的挤压固定。当然，在挤压变形后，第一侧壁与第二侧壁也可不挤压屏幕，而只是刚好变 形到与屏幕无缝贴合的位置，即是说，金属壳的侧壁只是刚好与屏幕贴合，而与屏幕之间没有挤压力，该种情况下，可通过底部双面胶或点胶的固定方式将屏幕胶合固定在金属壳的预设位置上，以实现屏幕在金属壳体内的最终固定。
优选地，屏幕即采用底部双面胶或点胶的固定方式将屏幕胶合固定在金属壳的预设位置上，又利用冷挤压工艺使金属壳的侧壁挤压屏幕，从而在实现金属壳与屏幕无缝贴合的同时，又能够实现金属壳与屏幕之间的胶合和挤压的双重固定。
在上述技术方案中，优选地，所述金属壳的侧壁设置成环形，其中，所述金属壳的侧壁向所述金属壳内变形后，挤压所述屏幕并与所述屏幕无缝贴合。
在该技术方案中，环形可以是三角形、四边形等多边形以及圆形，当然，也可以是多边形、圆形、弧形等相互结合的形状，具体地，该环形与屏幕的形状一致，从而通过冷挤压能够使屏幕与金属壳的侧壁之间既能够实现无缝贴合，又能够实现相互之间的挤压固定。
在上述技术方案中，优选地，变形后的所述金属壳的侧壁包括有一包边，所述包边无缝贴合于所述屏幕。
在该技术方案中，可将金属壳的上端面设置的较高于屏幕的上端面，从而便可在屏幕的侧壁及上端面上形成包边，优选地，该包边与屏幕之间也为无缝贴合。
在上述技术方案中，优选地，所述金属壳为铝合金壳，所述屏幕为触摸屏。
本发明第二方面提供一种终端的组装方法，该终端的组装方法采用第一方面任一项实施例提供的屏幕的安装方法进行终端的屏幕安装，其中，在安装所述屏幕之前还包括：将屏幕面板以及屏幕模组组装成所述屏幕。
在该技术方案中，终端的屏幕通过第一方面任一项实施例所述的屏幕的安装方法进行屏幕安装，因而安装后的屏幕与终端的金属壳之间将无任何缝隙，从而可避免终端的缝隙处出现积灰等现象。而具体地，终端屏幕包括屏幕面板以及屏幕面板下的屏幕模组，而在具体挤压安装过程中，可对屏幕面板以及屏幕模组同时进行挤压安装。
本发明第三方面提供一种终端，该终端采用第二方面提供的终端的组装方法组装而成，从而该终端的金属壳与终端屏幕之间无任何缝隙。

步骤102，将屏幕安装在金属壳内的预设位置上；
该步骤中，预设位置为屏幕在金属壳内的待安装位置，比如对于手机等移动终端而言，金属壳的一端面为敞口，屏幕一般镶嵌在敞口处，因此，预设位置便为该敞口处。
步骤104，利用冷挤压模具挤压所述金属壳的侧壁，使所述金属壳的侧壁向所述金属壳内变形，并与所述金属壳内的所述屏幕无缝贴合。
该步骤中，在具体挤压金属壳时，可预先设置一个专用的冷挤压模具 并在该冷挤压模具上加工出与壳体的形状、大小一致的模腔，以便该冷加压模具可刚好套设在金属壳外，从而便可利用该冷挤压模具同时挤压金属壳的外侧，以实现金属壳的一次挤压成型，进而可提高屏幕的安装效率。
在该技术方案中，将屏幕安装在金属壳内的预设位置上后，通过挤压金属壳，可使金属壳向靠近屏幕的方向产生塑性变形，从而该塑性变形可填补屏幕与金属壳之间的缝隙并使金属壳与屏幕的侧壁紧密贴合，进而在将屏幕装配到金属壳上后，可实现屏幕与金属壳之间的无缝安装。同时，该挤压过程采用冷挤压模具进行冷挤压，即不加热的情况下挤压，从而可防止金属壳内的电子元件受热损坏的情况发生。
在上述技术方案中，优选地，在所述将屏幕安装在金属壳内的预设位置上之前，还包括：在所述屏幕的四周加工出倒角。
在该技术方案中，倒角可加大金属壳的变形量，从而在金属壳变形后，金属壳上能够对应地形成与倒角相适应的斜面，该斜面能够进一步阻止屏幕从金属壳内滑出，从而能够提高屏幕安装的可靠性。
在上述技术方案中，优选地，所述倒角的角度大于0°小于90°。
在该技术方案中，倒角的角度优选为30°至60°。
在上述技术方案中，优选地，将所述屏幕安装在金属壳内的预设位置上，包括：将所述屏幕胶合在所述预设位置上或利用所述金属壳内的限位件将所述屏幕限位在所述预设位置上。

同时，该技术方案中，也可直接通过底部双面胶或点胶的固定方式实现屏幕在金属壳体内的最终固定，从而不需要利用金属壳的侧壁对屏幕进行夹紧固定，即是说，在该种情况下，金属壳的侧壁在变形后，金属壳的侧壁只需要与屏幕无缝贴合即可，而不需要为屏幕提供夹紧固定力。
在上述技术方案中，优选地，所述金属壳的侧壁包括两个相对设置的第一侧壁和第二侧壁，其中，所述第一侧壁和所述第二侧壁向所述金属壳内变形后，挤压所述屏幕并与所述屏幕无缝贴合。
在该技术方案中，金属壳的侧壁包括两个相对设置的第一侧壁和第二侧壁，从而从金属壳的两边同时向内挤压第一侧壁和第二侧壁时，第一侧壁和第二侧壁便可从屏幕的两边向内变形并夹紧屏幕，从而即可实现屏幕与金属壳之间的无缝贴合，又可实现金属壳的侧壁对屏幕的挤压固定。当然，在挤压变形后，第一侧壁与第二侧壁也可不挤压屏幕，而只是刚好变形到与屏幕无缝贴合的位置，即是说，金属壳的侧壁只是刚好与屏幕贴合，而与屏幕之间没有挤压力，该种情况下，可通过底部双面胶或点胶的固定方式将屏幕胶合固定在金属壳的预设位置上，以实现屏幕在金属壳体内的最终固定。
优选地，屏幕即采用底部双面胶或点胶的固定方式将屏幕胶合固定在金属壳的预设位置上，又利用冷挤压工艺使金属壳的侧壁挤压屏幕，从而在实现金属壳与屏幕无缝贴合的同时，又能够实现金属壳与屏幕之间的胶合和挤压的双重固定。
在上述技术方案中，优选地，所述金属壳的侧壁设置成环形，其中，所述金属壳的侧壁向所述金属壳内变形后，挤压所述屏幕并与所述屏幕无缝贴合。
在该技术方案中，环形可以是三角形、四边形等多边形以及圆形，当然，也可以是多边形、圆形、弧形等相互结合的形状，具体地，该环形与屏幕的形状一致，从而通过冷加压能够使屏幕与金属壳的侧壁之间既能够实现无缝贴合，又能够实现相互之间的挤压固定。
在上述技术方案中，优选地，变形后的所述金属壳的侧壁包括有一包边，所述包边无缝贴合于所述屏幕。
在该技术方案中，可将金属壳的上端面设置的较高于屏幕的上端面，从而便可在屏幕的侧壁及上端面上形成包边，优选地，该包边与屏幕之间也为无缝贴合。
在上述技术方案中，优选地，所述金属壳为铝合金壳，所述屏幕为触摸屏。
图2示出了根据本发明的一个实施例的终端的组装方法的流程示意图。
如图2所示，本发明第二方面提供一种终端的组装方法，包括：
步骤202，将屏幕面板以及屏幕模组组装成所述屏幕；
步骤204，将所述屏幕安装在金属壳内的预设位置上；
步骤206，利用冷挤压模具挤压所述金属壳的侧壁，使所述金属壳的侧壁向所述金属壳内变形，并与所述金属壳内的所述屏幕无缝贴合。
在该技术方案中，终端的屏幕通过第一方面任一项实施例所述的屏幕的安装方法进行屏幕安装，因而安装后的屏幕与终端的金属壳之间将无任何缝隙，从而可避免终端的缝隙处出现积灰等现象。而具体地，终端的屏幕包括屏幕面板以及屏幕面板下的屏幕模组，而在具体挤压安装过程中，可对屏幕面板以及屏幕模组同时进行挤压安装。
图3示出了根据本发明的一个实施例的终端的结构示意框图。
本发明第三方面提供一种终端300，该终端300采用第二方面提供的终端的组装方法组装而成，从而该终端的金属壳310与终端的屏幕320之间无任何缝隙。
下面结合图4来描述本发明的一个具体实施例提供的屏幕的安装方法的流程示意图。
如图4所示，该实施例提供的屏幕的安装方法包括：
步骤402，在屏幕的四周加工出倒角；
在该步骤中，倒角可加大金属壳的变形量，从而在金属壳变形后，金属壳上能够对应地形成与倒角相适应的斜面，该斜面能够进一步阻止屏幕从金属壳内滑出，从而能够提高屏幕安装的可靠性。
步骤404，将所述加工有倒角的屏幕安装在金属壳内的预设位置上；
在该步骤中，可通过底部双面胶或点胶的固定方式将屏幕胶合安装在金属壳的预设位置上，或者还可通过在金属壳的内壁上设置支撑块等限位件的方式将屏幕限位安装在金属壳的预设位置上，通过上述方式，能够对屏幕起到初步定位的作用，从而可防止在冷挤压过程中，屏幕出现挪动或倾斜的现象，从而可确保挤压安装后，屏幕依旧能够精准的安装在预设位置上。
步骤406，利用冷挤压模具挤压所述金属壳的侧壁，使所述金属壳的侧壁向所述金属壳内变形，并与所述金属壳内的所述屏幕无缝贴合。
在该步骤中，挤压过程采用冷挤压工艺，即不加热的情况下挤压，从而可防止金属壳内的电子元件受热损坏的情况发生。具体地，该步骤包括：
将冷挤压模具套设在带有屏幕的金属壳上；
按压冷挤压模具；
其中，挤压完成后，取下挤压模具即可完成屏幕的安装。
综上，该实施例通过在屏幕上加工出倒角，从而可为金属壳的侧壁提供一定的变形空间，增大了金属壳的变形量，进而增大了金属壳对屏幕的挤压安装力，同时，在具体将屏幕安装在金属壳内的预设位置上即待安装位置上时，可在金属壳的内壁上设置支撑块等限位件，以对屏幕的安装位置进行预定位，当然，也可通过底部双面胶或点胶的固定方式实现屏幕的预定位，从而在利用冷挤压模具挤压金属壳时，屏幕在金属壳内不会出现屏幕挪动或倾斜的现象。此外，由于该实例中采用了冷挤压工艺，因而不需要对金属壳进行加热，从而简化了步骤，也避免了金属壳内的电子元件受热而发生损坏的情况，同时，由于采用冷挤压工艺，金属壳的侧壁可以向屏幕的方向产生足够大的变形量，以填补金属壳与屏幕之间的缝隙，并进而与屏幕的侧壁紧密贴合，进而可简单、方便地实现屏幕与金属壳之间的无缝安装。
此外，在步骤404中，也可直接通过底部双面胶或点胶的固定方式实现屏幕在金属壳体内的最终固定，从而在步骤406中，便不需要利用金属壳的侧壁对屏幕进行夹紧固定，即是说，在该种情况下，金属壳的侧壁在变形后，金属壳的侧壁只需要与屏幕无缝贴合即可，而不需要为屏幕提供夹紧固定力。
下面结合图5至图9来具体描述本发明提供的屏幕的安装方法、终端的组装方法及终端。
具体地，如图5和图6所示，可先将屏幕面板11组装在屏幕模组12上以形成待安装的屏幕1，再在屏幕1上加工出倒角13，然后将屏幕1安装在金属壳2的预设位置上，其中，屏幕1的下端面可用限位件抵住，而由图6中可知，此时，屏幕1与金属壳2之间包括有组装缝隙3。
此后，如图7所示，将冷挤压模具4套设在金属壳2的上端，并在挤压模具4上施加如图7所示的力F。
之后，取下挤压模具4，得出如图8所示的终端，即实现了屏幕的安装以及终端的组装。其中，由图9可知，通过该种方法组装的终端，屏幕1与金属壳2之间没有任何组装缝隙。
以上仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
