Description

一种液晶面板注塑包装箱 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包装箱。
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，在运输中传统的包装方式由于不能较好地承载外部压力，可能使多层堆叠的液晶面板产生变形，不仅影响使用效果，而且给企业带来不必要的损失。其主要原因为：传统注塑包装箱的凸起结构和加强筋壁较厚，在包装箱注塑成型时，由于收缩不均匀造成凸起结构下凹，随着注塑包装箱承载产品的时间增加，凸起结构下凹越来越严重，凸起结构下凹的存在导致了注塑包装箱体在堆叠时压迫箱内液晶面板，影响液晶面板的品质，同时，凸起结构下凹的注塑包装箱不利于回收使用，增加了包装成本。
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包装箱，通过包装箱凸起结构上凸和加强筋内凹的结构，避免注塑箱底部下凹现象的发生。
为了达到上述发明目的，本发明采用了如下的技术方案：
一种液晶面板注塑包装箱，包括箱体，所述箱体由侧壁板和底面板组成，其中，所述底面板设置有凸起结构，向所述箱体内凸起。
进一步地，所述凸起结构由上表面和下表面组成。
进一步地，所述上表面和下表面均为向上凸的圆弧曲面。
进一步地，所述上表面为向上凸的圆弧曲面，所述下表面为平面。
进一步地，所述上表面和下表面均为平面。
进一步地，所述下表面的外侧设置有若干条加强筋，所述加强筋包括刚性端和柔性端，所述刚性端位于加强筋的两侧，所述柔性端位于加强筋的中间。
进一步地，所述刚性端的高度大于所述柔性端的高度。
进一步地，所述加强筋的外缘为沿所述箱体外侧向箱体内侧凹陷的圆弧。
进一步地，所述若干条加强筋呈十字交叉状分布于所述凸起结构的下表面上。
进一步地，所述侧壁板围绕在所述凸起结构的四周，与凸起结构围合形成容置空间。
本发明的有益效果：
本发明提供的一种液晶面板注塑包装箱，结构简单，增加了注塑包装箱的抗弯曲强度，解决了注塑箱底部下凹的问题，同时，避免了注塑包装箱相互叠置而影响液晶面板品质的问题，增加注塑包装箱回收次数，降低包装成本。
附图说明
图1是本发明实施例液晶面板注塑包装箱的示意图。
图2是本发明实施例1液晶面板注塑包装箱的凸起结构示意图。
图3是本发明实施例2液晶面板注塑包装箱的凸起结构示意图。
图4是本发明实施例2液晶面板注塑包装箱的底部示意图。
图5是本发明实施例3液晶面板注塑包装箱的凸起结构示意图。
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。
参阅图1，一种液晶面板注塑包装箱，包括箱体10，该箱体10由侧壁板100和底面板200组成，其中，该底面板200设置有凸起结构210，该凸起结构210位于侧壁板10之中，侧壁板10围绕在凸起结构210的四周，与凸起结构200围合形成容置空间300，该容置空间300用于放置液晶面板310。
实施例1
参阅图2，该凸起结构210由上表面211和下表面212组成，本实施例的上表面211、下表面212均为向上凸的圆弧曲面。在承载液晶面板时，液晶面板先与凸起结构210的上表面211接触，圆弧曲面状的凸起结构210产生屈服应力支撑液晶面板，但是，由于液晶面板存在自身重力以及多个液晶面板的叠置，使液晶面板的重力大于凸起结构210的屈服应力，当液晶面板放置于箱体10内时，凸起结构210向箱体10内凸起的效果被抵消，凸起结构210为平面板，不影响液晶面板放置于箱体10内的平整性。当液晶面板从箱体10内部移出时， 凸起结构210的屈服强度保证了凸起结构210能够恢复原状，有效抑制了箱体10底部下凹。
实施例2
参阅图3、图4，该凸起结构210的上表面211为向上凸的圆弧曲面或者平面，下表面212为平面，该下表面212的外侧设置有若干条加强筋230。本实施例中凸起结构210的上表面为平面，该加强筋230包括刚性端231和柔性端232，该刚性端231位于加强筋230的两侧，该柔性端232位于加强筋230的中间，刚性端231的高度大于柔性端232的高度，使得加强筋230的外缘为沿箱体10外侧向箱体10内侧凹陷的圆弧，从而该凸起结构210呈凹透镜状。由于刚性端231的高度大于柔性端232的高度，使得箱体10的底面板200四周强度大于底面板200中心强度，对承载液晶面板产生的底部下凹现象具有抑制作用，同时，该若干条加强筋230呈十字交叉状位于凸起结构210的下表面212上，有效地增加了箱体10的抗弯曲强度，极大地改善了注塑包装箱底部下凹的问题。另外，在多个装有液晶面板的箱体10相互叠置时，刚性端231还具有支脚的作用，增加了相互叠置箱体之间的距离，避免了上端叠置的箱体压到下端叠置箱体内的液晶面板。
实施例3
参阅图5，本实施例中该凸起结构210的上表面211为向上凸的圆弧曲面，下表面212为平面，每一条加强筋230均设置于下表面212上，位于该底面板200的外侧。由于该凸起结构210的上表面211为向上凸的圆弧曲面，下表面连接呈凹陷状的加强筋230，具有对箱体10底部下凹问题起到双重抑制效果，使箱体10具有更好的屈服强度，对防止包装箱底部下凹具有更好的技术效果，适 用于承载大尺寸液晶面板的包装箱。
综上所述，本发明提供的一种液晶面板注塑包装箱，结构简单，增加了注塑包装箱的抗弯曲强度，解决了注塑箱底部下凹的问题，同时，避免了注塑包装箱相互叠置而影响液晶面板品质的问题，增加注塑包装箱回收次数，降低包装成本。
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。
