【具体实施方式】
下面结合附图和实施方式进行详细说明。
请参阅图1和图2，图1是本发明背光模组的装配方法实施方式的流程图，图2是本发明背光模组的装配方法实施方式中的反射片、导光板以及光学模片叠置成一个组件整体的示意图。如图所示，所述方法包括：
S101: 使反射片113、导光板112以及光学膜片111叠置成一个组件整体11，并整体固定；
其中，固定组件整体11是通过自动化设备实现，但固定组件整体11的方式不作限定，只要不影响装配背板即可，在本发明实施方式中，其中一种固定组件整体11的方式为：先通过定位机构在平台上依次定位好反射片、导光板以及光学膜片；再上下夹持固定反射片、导光板以及光学膜片以形成组件整体，并撤掉平台及其定位机构，在撤掉平台及其定位机构后，组件整体的四周预留固定主连接件的空间，以不影响装配主连接件。

主连接件又可包括至少两个副连接件，至少两个副连接件连接固定形成主连接件。副连接件间可通过卡合固定、螺接固定、焊接固定或者胶水固定等。主连接件分拆成至少两个副连接件，并优化设计，使得不同尺寸的主连接件可使用相同的副连接件，实现模具共用，降低模具成本，进而降低产品成本。
如图3、图4、图5和图6所示，主连接21包括第一副连接211和第二副连接件212，第一副连接211和第二副连接件212连接固定形成主连接件21。主连接22包括第三副连接221、第四副连接件222和第五副连接223。第三副连接221、第四副连接件222和第五副连接223连接固定形成主连接22。其中，第一副连接211与第三副连接221相同，第二副连接件212与第四副连接件222相同。因此，第一副连接211与第三副连接221可使用相同的模具制作，第二副连接件212与第四副连接件222可使用相同的模具制作，实现模具共用，降低模具成本。
形成背板的主连接件的数量至少为两个，至少两个主连接件首尾连接固定，以围绕形成背板，其中主连接间通过卡合固定、螺接固定、焊接固定或者胶水固定等。以下以背板的主连接件的数量为四个为例进行说明。
请进一步参阅图7和图8，图7为本发明背光模组的装配方法实施方式中的背板的主连接件的数量为四个时的结构示意图，图8是本发明背光模组的装配方法实施方式中的背板的主连接件的数量为四个时装配背光模组的示意图。如图所示，背板30包括第一主连接件301、第二主连接件302、第三主连接件303和第四主连接件304，第一主连接件301、第二主连接件302、第三主连接件303和第四主连接件304的形状均为直条形，并且在装配时首尾连接固定，以围绕形成背板30。在装配时，先将反射片113、导光板112以及光学膜片111叠置成一个组件整体31。再通过自动化设备分别固定背板30的第一主连接件301和第三主连接件303于组件整体31的前后两侧，接着再分别固定背板30的第二主连接302和第四主连接件304于组件整体31的左右两侧。当然，固定背板30的主连接件于组件整体31的四周的方式不限于上述的方式，只要实现固定背板30的主连接件于组件整体31的四周，使得反射片313、导光板312以及光学膜片313分别固定于背板30相应的位置即可，例如：每次仅固定一个主连接件或者先同时固定其中三个主连接件，再固定最后一个主连接件。
在本发明实施方式中，先将反射片、导光板以及光学膜片叠置成一个组件整体，并整体固定，再使首尾连接固定形成背板的至少两个主连接件分别固定于组件整体的四周，从而使得反射片、导光板以及光学膜片分别固定于背板相应的位置。而上述装配背光模组的方式，适合通过自动化设备实现，通过自动化设备装配背光模组，有利于提高装配背光模组的效率，减少装配背光模组的人员数量，降低人工成本。
本发明又提供了一种背光模组的装配设备实施方式。请参阅图9和图2，图9为本发明背光模组的装配设备实施方式的结构示意图。如图所示，所述装配设备40包括固定装置41和装配装置42。固定装置41用于将反射片113、导光板112以及光学膜片111叠置成一个组件整体11，并整体固定。固定装置41包括平台412和夹持单元411，平台412中空，四周设有定位机构4121，夹持单元411包括上夹持单元4111和下夹持单元4112，下夹持单元4112位于平台412中空位置。定位机构4121在平台412上依次定位好反射片113、导光板112以及光学膜片111，
上夹持单元4111和下夹持单元4112上下夹持固定反射片113、导光板112以及光学膜片111以形成组件整体11，并撤掉平台412及其定位机构4121，在撤掉平台412及其定位机构4121后，组件整体11的四周预留固定背板的空间。
装配装置42用于将首尾连接固定形成背板的至少两个主连接件分别固定于组件整体11的四周，从而使得反射片113、导光板112以及光学膜片111分别固定于背板相应的位置。
背板的主连接件的数量至少为两个，至少两个主连接件首尾连接固定，以围绕形成背板，其中主连接间通过卡合固定、螺接固定、焊接固定或者胶水固定等。在本发明实施方式中，背板的主连接件的数量可选为四个，再参阅图7和图8，背板30包括第一主连接件301、第二主连接件302、第三主连接件303和第四主连接件304，第一主连接件301、第二主连接件302、第三主连接件303和第四主连接件304的形状均为直条形，并且首尾连接固定，以围绕形成背板30。装配装置42先分别固定背板30的第一主连接件301和第三主连接件303于组件整体31的前后两侧，接着再分别固定背板30的第二主连接302和第四主连接件304于组件整体31的左右两侧，从而使得反射片313、导光板312以及光学膜片311分别固定于背板相应的位置。
其中，主连接件又可包括至少两个副连接件，至少两个副连接件连接固定形成主连接件，将主连接件分拆成至少两个副连接件时，进行优化设计，使得不同尺寸的主连接件可使用相同的副连接件，实现模具共用，降低模具成本，进而降低产品成本。再次参阅图3和图4。主连接21包括第一副连接211和第二副连接件212，第一副连接211和第二副连接件212连接固定形成主连接件21，主连接22包括第三副连接221、第四副连接件222和第五副连接223，第三副连接221、第四副连接件222和第五副连接223连接固定形成主连接22，其中，第一副连接211与第三副连接221相同，第二副连接件212与第四副连接件222相同，因此，第一副连接211与第三副连接221可使用相同的模具制作，第二副连接件212与第四副连接件222可使用相同的模具制作，实现模具共用，降低模具成本。
在本发明实施方式中，固定装置将反射片、导光板以及光学膜片叠置成一个组件整体，并整体固定，装配装置将首尾连接固定形成背板的至少两个主连接件分别固定于组件整体的四周，从而使得反射片、导光板以及光学膜片分别固定于背板相应的位置。而固定装置和装配装置均适合配置为自动化设备，自动化设备装配背光模组，有利于提高背光模组的装配效率，减少装配背光模组的人员数量，降低人工成本。
以上所述仅为本发明的实施方式，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。
