Description

组装贴合设备 技术领域
本发明属于自动化设备领域，具体地讲，涉及一种用于组装贴合片状元件的组装贴合设备。

在传统的平面背光模块中，其光学片材的组装工艺通常是采用光学片材平面裁切和光学片材平面吸附的方式进行。一般而言，光学片材包含扩散片、增光片、反射片等，它们都是以卷料方式运送。
如果以与传统的平面背光模块中光学片材的组装工艺相同的方式对曲面背光模块进行组装，那么在对光学片材弯曲的过程中，光学片材存在内生应力，且光学片材的内外表面的延生与压缩不一致会导致光学片材褶皱不平，甚至发生连接胶的脱落或是光学片材的翘曲。这样，会影响曲面背光模块的光学品味，并且会使曲面背光模块中的结构连接强度较弱，最终影响到曲面背光模块的品质。

附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是根据本发明的实施例的组装贴合设备的结构示意图；
图2是根据本发明的另一实施例的吸附装置的结构示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中，为了清楚起见，夸大了层和区域的厚度。相同的标号在附图中始终表示相同的元件。
图1是根据本发明的实施例的组装贴合设备的结构示意图。在本实施例中，以利用组装贴合设备将光学片材组装贴合到待组装贴合光学片材的曲面背光模块为例进行说明，本发明的组装贴合设备并不局限运用于此。
参照图1，根据本发明的实施例的组装贴合设备包括：吸附装置100、传动装置200。
吸附装置100用于吸附多张光学片材300。传动装置200设置在吸附装置100的下方，或称传动装置200与吸附装置100相对设置。传动装置200用于对多个待组装贴合光学片材的曲面背光模块400进行水平传动，即传动装置200能够将每个曲面背光模块400传动到吸附装置100的正下方，以使一个曲面背光模块400与一张光学片材300正相对。
当传动装置200将一个曲面背光模块400水平传动至吸附装置100的正下方时，吸附装置100将吸附的一张光学片材300正对该一个曲面背光模块400，吸附装置100靠近传动装置200，吸附装置100解除对该一张光学片材300的吸附，使该被解除吸附的一张光学片材300组装贴合到该一个曲面背光模块400。这样，就完成了一张光学片材300组装贴合到一个曲面背光模块400的过程。
在完成了一张光学片材300组装贴合到一个曲面背光模块400之后，吸附装置100远离传动装置200，传动装置200对下一个曲面背光模块400进行水平传动；当传动装置200将下一个曲面背光模块400水平传动至吸附装置100的正下方时，吸附装置100吸附的下一张光学片材300正对下一个曲面背光模块400，吸附装置100靠近传动装置200，吸附装置100解除对下一张光学片材300的吸附，使被解除吸附的下一张光学片材300组装贴合到下一个曲面背光模块400。如此循环，即可将吸附装置100吸附的每张光学片材300都组装贴合到对应的曲面背光模块400。
进一步地，吸附装置100能够进行自旋转。这样，当传动装置200将一个曲面背光模块400水平传动至吸附装置100的正下方时，吸附装置100通过自旋转而将吸附的一张光学片材300正对该一个曲面背光模块400。这样，通过吸附装置100的自旋转，可将吸附装置100吸附的每张光学片材300都组装贴合到对应的曲面背光模块400。
为了能够使吸附装置100靠近或远离传动装置200，在本实施例中，吸附装置100还能够进行上下运动；其中，当吸附装置100向下运动时，吸附装置100靠近传动装置200；当吸附装置100向上运动时，吸附装置100远离传动装置200。
具体地，传动装置200包括：传动平台210以及多个曲面定位冶具220。
传动平台210沿着水平方向进行传动，在本实施例中，传动平台可利用一步进电机(未示出)来进行水平方向的传动，但本发明并不局限于此。传动平台210的表面具有多个下凹的曲面凹槽211；其中，该曲面凹槽211的曲率与曲面定位冶具220的曲率匹配。每个曲面定位冶具220置于对应的一个曲面凹槽211中，每个曲面定位冶具220用于承载且定位一个曲面背光模块400。
吸附装置100包括：卷轴110以及设置在卷轴110中的吸附槽120和驱动组件130。
卷轴110整体呈圆柱形，其截面形状为圆形。吸附槽120设置在卷轴110中并延伸至卷轴110的表面(或称柱面)，吸附槽120能够将光学片材300吸附在卷轴110的表面。而驱动组件130用于驱动卷轴110进行自旋转及上下运动。
进一步地，在本实施例中，吸附槽120的数量八根，但本发明并不限制于此，例如，吸附槽120的数量可以根据实际情况设置。这八根吸附槽120沿着卷轴110的截面圆周等弧度设置，每根吸附槽120吸附一张光学片材300。
此外，在本实施例中，这八根吸附槽120互相贯通。这样，在对光学片材300进行吸附时，这八根吸附槽120通过贯通的管道抽压而一起吸附八张光学片材300；而当传动平台210将一个曲面背光模块400水平传动至卷轴110的正下方时，卷轴110自旋转，使这八根吸附槽120之一将吸附的一张光学片材300正对一个曲面背光模块400；驱动组件130驱动卷轴110向下运动，使卷轴110靠近传动平台210；这八根吸附槽120之一解除对其吸附的一张光学片材300的吸附，使被解除吸附的一张光学片材300组装贴合到一个曲面背光模块400。
此外，在本实施例中，驱动组件130包括旋转马达131及上下运动驱动单元(例如气缸)132；其中，旋转马达131用于驱动卷轴110进行自旋转，而上下运动驱动单元(例如气缸)132用于驱动卷轴110进行上下运动。
作为本发明的另一实施方式，图2是根据本发明的另一实施例的吸附装置的结构示意图。参照图2，与图1所示的吸附装置不同的是：八根吸附槽120各自独立。这样，在对光学片材300进行吸附时，这八根吸附槽120分别独立 抽压而各自吸附一张光学片材300；而当传动平台210将一个曲面背光模块400水平传动至卷轴110的正下方时，卷轴110自旋转，使这八根吸附槽120之一将吸附的一张光学片材300正对一个曲面背光模块400；驱动组件130驱动卷轴110向下运动，使卷轴110靠近传动平台210；这八根吸附槽120之一解除对其吸附的一张光学片材300的吸附，使被解除吸附的一张光学片材300组装贴合到一个曲面背光模块400。
综上所述，根据本发明的实施例的组装贴合设备，其在组装贴合光学片材(诸如光学膜片、光学胶带、反射片等)时，能够保持光学片材自身的应力方向，使光学片材更好地吻合曲面背光模块的曲率，从而使光学片材不会出现褶皱不平、脱落或翘曲等不良现象。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
