Description

一种液晶面板注塑箱 技术领域
本发明涉及液晶面板制造包装领域，尤其涉及一种液晶面板注塑箱。
背景技术
在电子行业中，电子产品的生产装配需要复杂的供应链支持。通常，电子产品的零部件在不同地方批量生产、制造，经过运输，统一运送至装配工厂进行组装。在液晶显示设备领域，液晶面板作为液晶显示设备的核心部件，在运输中需要考虑包装的可靠性。但是，在装载、运输过程中通常将装有液晶面板的包装箱相互堆叠，下层包装箱受到了多层堆叠后包装箱的挤压，由于传统的包装方式不能较好地承受外部压力，导致液晶面板产生变形，给企业带来不必要的损失。
传统注塑箱的底面板采用T型加强筋结构，底面板和加强筋壁较厚，在包装箱注塑成型时，由于收缩不均匀造成底面板下凹，随着注塑箱承载产品的时间增加，底面板下凹越来越严重，底面板下凹的存在导致了注塑箱体在堆叠时压迫箱内液晶面板，而这种底面板下凹的现象在包装箱注塑工艺上较难避免，同时，底面板下凹的注塑箱不利于回收使用，增加了包装成本。另外，在承载大尺寸液晶面板时，该种包装箱往往设计成大结构尺寸，增加了注塑箱的重量，不方便作业人员的工作，影响工作效率。
发明内容
本发明所要解决的技术问题是提供一种液晶面板注塑箱，加强注塑箱底部结构强度，提高注塑箱底部平面度，节省材料，实现一种尺寸大、重量轻的注塑箱。
为了达到上述发明目的，本发明采用了如下的技术方案：
一种液晶面板注塑箱，包括侧壁和底面板，所述侧壁围绕在所述底面板的四周，其中，所述底面板包括内底板和外底板，所述内底板与外底板之间设置有加强结构。
进一步地，所述加强结构由若干个单元组成，呈栅格状。
更进一步地，每一个所述单元均包括边框，所述边框连接所述内底板与外底板。
更进一步地，所述边框为多边形结构，与所述内底板和外底板围合形成的空间为中空。
更进一步地，所述边框为四边形，若干个所述四边形单元之间相互连接，使底面板的截面呈连续口字形结构。
更进一步地，所述边框为六边形，前后所述六边形单元依次连接，左右所述六边形单元交错连接，使所述加强结构呈蜂巢状。
本发明的有益效果：
本发明提供的一种液晶面板注塑箱，具有结构简单、节省材料、平面度高、结构紧凑、受力均匀的特点，使注塑箱的承载能力大大提高，不易变形，避免了注塑箱相互叠置而影响液晶面板品质的问题，增加注塑箱回收次数，降低包 装成本，解决了大尺寸注塑箱较重的问题。

具体实施方式
为了更好地阐述本发明的技术特点和结构，以下结合本发明的优选实施例及其附图进行详细描述。
实施例1
参阅图1至图3，一种液晶面板注塑箱，包括侧壁100和底面板200，该侧壁100围绕在底面板200的四周，其中，该底面板200包括内底板210和外底板230，该内底板210与外底板230之间设置有加强结构220，该加强结构220用于提高注塑箱的结构强度和减轻重量。
该加强结构220由若干个单元221组成，呈栅格状。其中，每一个单元221均包括边框21，该边框21位于底面板200的内部，连接底面板200的内底板210与外底板230，与内底板210和外底板230形成空心区域，该空心区域用于减轻注塑箱的重量。加强结构220设计成栅格状结构，使注塑箱平面度高，结构紧凑，受力均匀，极大地提高注塑箱的承载能力，不易变形，同时，栅格中每一单元221的内部为中空结构，有助于节省底面板材料，减少重量，解决了 大尺寸注塑箱较重的问题。
该加强结构220为多边形栅格，每一个单元221的边框21为多边形结构。在设计制造过程中，可根据承载液晶面板的数量和重量，选择边框21的类型、壁厚和直径的大小。本实施例选取加强结构220中每一个单元221的边框21为四边形，若干个所述四边形单元221之间相互连接，使底面板200的截面呈连续口字形结构，口字形的中间区域为空心，有助于减轻注塑箱的重量。
实施例2
参阅图4，本实施例选取加强结构220中每一个单元221的边框21为六边形，前后的六边形单元221依次连接，左右的六边形单元221交错连接，使该加强结构220呈蜂巢状，位于底面板200的内底板210和外底板230之间。由基础物理知识可知，箱体的抗压强度由四面侧壁提供，且两面侧壁相交形成的楞所产生的抗压强度最大，经合理推断，当楞的数量增多，箱体所产生的抗压强度越大，因此，六边形的加强结构220有助于提高注塑箱的结构强度和承载能力。
综上所述，本发明提供的一种液晶面板注塑箱，具有结构简单、节省材料、平面度高、结构紧凑、受力均匀的特点，使注塑箱的承载能力大大提高，不易变形，避免了注塑箱相互叠置而影响液晶面板品质的问题，增加注塑箱回收次数，降低包装成本，解决了大尺寸注塑箱较重的问题。
本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其他不同形式的变化或变动。这里无需也无法对所有的实施 方式予以穷举。凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明权利要求的保护范围之内。
