Description

液晶面板包装箱及其成型方法
技术领域
本发明涉及包装箱领域，尤其涉及一种液晶面板包装箱及其成型方法。
背景技术
液晶面板包装箱设计中，基于成本考量，箱体的发泡倍率选择越来越高，这样的方式也带来了新的问题，那就是箱体的四个角落用于支撑玻璃的位置强度不足，现有设计一般采用增加扣件放置到各个角落来增强对应位置的强度，这些扣件也可采用注塑成型。这样搭配之后的组合箱体，因为搭配公差以及各个部品制造公差的问题，很难保证组合箱体的尺寸，也增加了制造难度。
发明内容
鉴于现有技术存在的不足，本发明提供了一种保证强度、制造方便、精度要求低的液晶面板包装箱及其成型方法。
为了实现上述的目的，本发明采用了如下的技术方案：
一种液晶面板包装箱，包括中间开槽的箱体和角部缓冲部，所述角部缓冲部一体形成于所述箱体内壁的四个角处，并凸出于所述箱体的内壁。
优选地，所述箱体的四个角处的所述角部缓冲部的端面围成矩形区域。
优选地，至少一个所述角部缓冲部由多个凸出高度相同的子缓冲部组成。
优选地，每个所述角部缓冲部与所述箱体内壁在四个角处的相应交线间隔一段距离。
优选地，所述角部缓冲部的材料强度大于所述箱体。
或者，所述角部缓冲部的发泡倍率低于所述箱体。
本发明的另一目的在于提供一种液晶面板包装箱的成型方法，所述液晶面板包装箱包括中间开槽的箱体和凸出于所述箱体内壁的四个角处的角部缓冲部，所述箱体和所述角部缓冲部发泡成型。
优选地，所述角部缓冲部的材料强度大于所述箱体。
或者，所述角部缓冲部的发泡倍率低于所述箱体。
优选地，至少一个所述角部缓冲部由多个凸出高度相同的子缓冲部组成。
本发明采用复合成型的方式，在箱体的四个角处一体形成有角部缓冲部，提高了箱体的支撑强度，同时，避免了组合装配的方式带来的尺寸不稳定情况发生。另外，将角部缓冲部的强度设置成高于箱体部分，可以提高用于支撑玻璃位置的强度，提高了液晶面板包装箱整体的强度。
附图说明
图1为本发明实施例1的液晶面板包装箱的结构示意图。
图2为本发明实施例1的液晶面板包装箱的产品堆放示意图。
图3为本发明实施例2的液晶面板包装箱的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例1
参阅图1，本实施例的液晶面板包装箱包括中间开槽的箱体10和角部缓冲部20，角部缓冲部20采用发泡工艺一体形成于箱体10内壁的四个角处，并凸出于箱体10的内壁。
如图2，箱体10的四个角处的角部缓冲部20的端面围成矩形区域，用于弹性接触放入其中的液晶面板的四个角，起到缓冲支撑和保护的作用。
本实施例中，角部缓冲部20的端面平行于箱体10内壁，其侧面垂直于相应的箱体10内壁，便于制造。在其他实施方式中，角部缓冲部20的侧面也可以相对于相应的箱体内壁倾斜设置，角部缓冲部20的端面还可设置凸包或条纹状凸筋或粘贴耐磨的橡胶、硅胶片，增大与液晶面板的摩擦力，提高支撑可靠性。
优选地，每个角部缓冲部20与箱体10内壁在四个角处的相应交线间隔一段距离，使得在每个角部处，相邻的两个内壁上的角部缓冲部20之间形成缺口11，使得当角部缓冲部20受力过大或使用年限过长导致变形后，可允许其朝缺口11方向产生一定的微变形。
为进一步提高用于支撑玻璃位置的强度，角部缓冲部20的强度高于箱体部分，具体是在发泡工艺过程中，使角部缓冲部20的发泡倍率低于箱体10，或者使位于角部缓冲部20的材料强度大于箱体10，使得受力集中的角部缓冲部20的局部强度高于其它非受力部位。
由于角部缓冲部与箱体一体发泡成型，降低了制造精度要求和制造难度，不需要考虑二者配合精度造成的尺寸不稳定的情况发生。
本发明的另一目的在于提供一种液晶面板包装箱的成型方法，将凸出于箱体10内壁的四个角处的角部缓冲部20与箱体10一起发泡成型，发泡材料可以是聚苯乙烯、聚氨酯、聚氯乙烯、聚乙烯、脲甲醛、酚醛等，在发泡工艺过程中，仅选用强度较大的材料制造角部缓冲部20，或者使角部缓冲部20的发泡倍率低于箱体10，一方面节约了成本，另一方面也保证了受力部的强度。
实施例2
如图3，与实施例1不同的是，本实施例的至少一个角部缓冲部20由若干个凸出高度相同的子缓冲部21组成。每个子缓冲部21在箱体10的高度方向上成排设置，或者也可以在箱体10侧壁的长度方向成排设置，仅在相邻的两个子缓冲部21之间设计微小间隙，每个子缓冲部21都可以允许有微小变形，即使一个子缓冲部21磨损或损坏，相邻的子缓冲部21仍可进行有效支撑和缓冲，提高了包装箱的可靠性和使用寿命。
由于采用复合成型的方式，在箱体的四个角处一体形成有角部缓冲部，提高了箱体的支撑强度，同时，也避免了组合装配的方式带来的尺寸不稳定情况发生。另外，将角部缓冲部的强度设置成高于箱体部分，可以提高用于支撑玻璃位置的强度，提高了液晶面板包装箱整体的强度。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
