Description

智能平板一体机及其组装方法 技术领域
本发明涉智能平板技术领域，特别是涉及智能平板一体机及其组装方法。
背景技术
随着智能平板设备相关技术的发展，对智能平板设备的生产组装效率要求也越来越高。传统的智能平板设备的零部件很分散，零部件的数量也很多，包括屏、钢化玻璃、前框、红外框、后壳等，安装时工艺非常复杂。例如在组装屏时，需要通过固定架先进行固定才能将屏组装好，同样在安装玻璃时也需要压块对玻璃进行定位才能将玻璃安装好，这种安装方式的效率非常低、安装成本也比较高。
并且，传统的智能平板设备在拆卸红外触摸模块时，需要先将后壳、屏、固定连接件等先拆出，然后才能从红外框中将红外触摸模块拆下，整个过程很繁琐，效率很低，不便于维修和更换，给用户造成了不便。
发明内容
基于此，有必要针对上述安装及拆卸智能平板设备的效率低、成本高的问题，提供一种智能平板一体机及其组装方法。
为实现上述目的，本发明采用如下的技术方案：
一种智能平板一体机，包括：屏、玻璃、红外触摸模块、后壳以及多个屏支架；所述屏支架上设有卡槽，玻璃卡入卡槽内并与卡槽相配合；所述屏支架上还设有插槽，红外触摸模块置于插槽内并与插槽相配合；所述屏支架一侧还设有支撑台，各屏支架上的支撑台首尾相连形成屏框，屏安装于屏框中，后壳安装于屏的后背处。
本发明实施例中还提供一种用于智能平板一体机的屏支架，所述屏支架上设有用于卡入玻璃并与之相配合的卡槽以及用于插入红外触摸模块并与之相配合的插槽；所述屏支架还设有支撑台，多个屏支架上的支撑台首尾相连，形成用于支撑屏的屏框；所述插槽沿屏支架长度方向设置，所述卡槽位于支撑台与插槽之间。
本发明实施例中还提供一种用于智能平板一体机的红外触摸模块固定结构，包括转角盖以及多个屏支架，所述转角盖安装于相邻屏支架之间，多个所述屏支架首尾相连形成屏框，所述屏框的四周边框内设有插槽，多个红外触摸模块分别置于各个插槽内并与插槽相配合。
本发明实施例中还提供一种上述智能平板一体机的安装方法，包括以下步骤：
a、将转角盖座安装于相应的屏支架上，再将供智能平板设备使用的玻璃放置好，将四个屏支架置于玻璃四周，每个屏支架的卡槽对准玻璃的边缘，将四个屏支架分别卡入到玻璃的四周；
b、步骤a中的四个屏支架上的支撑台形成屏框，将屏放入屏框中，用螺丝穿过支撑台上的第二螺纹孔及屏背板上的第一螺纹孔将屏固定在屏框中；
c、将红外触摸模块的线路板固定于屏背板上；
d、将后壳固定在屏背板上；
e、将红外触摸模块及红外滤光条插入到各个屏支架上的插槽中；
f、将转角盖安装于相邻屏支架之间的转角盖座上。
本发明实施例的智能平板一体机中，玻璃通过多个屏支架上的卡槽共同作用实现定位，在卡槽的作用下，玻璃会保持平整，不会因为在外力作用下而变形，从而不会出现四角起翘而导致玻璃与前框间隙过大的现象，进而提高了产品的品质和合格率；并且本发明实施例中屏固定于多个支撑台形成的屏框中，红外触摸模块插入到屏支架上的插槽中，整个安装过程不需要用到任何定位块进行固定，节约了成本，同时提高了组装和拆卸效率，能满足大规模、模块化生产的需求。另外本发明的智能平板一体机的组装方法，采用这种方法安装时省去了传统结构中用到的玻璃、屏的定位块，降低了成本、提高了效率，屏背板减去了传统屏背板上的各种定位支架，使结构更加简单，成本更低，重量更轻，红外触摸模块直接插入到插槽中，拆装更加迅速，省去了传统结构中的很多工序，极大地提高了安装和拆卸效率。
