多组分多层复合电芯托盘及其制造方法
技术领域
本发明涉及一种多组分多层复合电芯托盘及其制造方法，属于包装,储藏,运输设备的制造及其应用技术领域。
背景技术
吸塑托盘是一种转运电池的载具，产品是通过吸塑成型工艺转化而成。塑料加工工艺主要原理是将平展的塑料硬片材加热变软后，采用真空吸附于模具表面，冷却后成型。
传统的吸塑托盘通常是由PS、PET、PP等吸塑原料制成，因为温度和制作工艺影响，吸塑托盘通常有且仅有一种材料或一种复合材料制成，无法兼顾强度和韧性，装载电池时，无法兼顾内部和外部环境，单一的吸塑托盘或硬或软，材料直接影响装载效果。所以需要一种能保证吸塑托盘的强度，另一方面又需要保护电芯的载具。
发明内容
有鉴于此，本发明的目的是提供一种重量轻，制作方便，装载效果好的多组分多层复合电芯托盘及其制造方法，既能保证强度，又能保护电芯。
本发明采用以下方案实现：一种多组分多层复合电芯托盘，包括基板，所述基板上表面覆盖有下衬层，所述下衬层上表面覆盖有型腔层，所述型腔层上开设有用以容纳电芯并贯通其上、下表面的电芯容纳腔；所述电芯容纳腔内设置有覆盖在下衬层上的下保护垫；电芯容纳腔内还设置有覆盖在电芯上的上保护垫以及覆盖在上保护垫上表面的上衬层。
进一步的，所述上衬层采用EVA 泡棉，所述上保护垫和下保护垫采用硅胶，所述型腔层和下衬层采用EVA泡棉，所述基板采用PVC板。
进一步的，所述上衬层和上保护垫通过双面胶或胶水粘连，所述型腔层和下保护垫通过双面胶或胶水与下衬层粘连，所述下衬层与基板通过双面胶或胶水粘连。
一种如上所述多组分多层复合电芯托盘的制造方法，包括以下步骤：（1）裁剪生产出基板、下衬层、型腔层、下保护垫、上保护垫和上衬层；（2）在型腔层上冲剪出电芯容纳腔；（3）将基板、下衬层、型腔层采用双面胶或胶水粘连；然后在型腔层的电芯容纳腔中放入下保护垫，下保护垫采用双面胶或胶水与下衬层粘连；（4）将上保护垫和上衬层采用双面胶或胶水粘连形成上盖，然后将电芯放入型腔层的电芯容纳腔中，并将上盖覆盖在电芯上。
与现有技术相比，本发明具有以下有益效果：本发明多组分多层复合电芯托盘通过将不同硬度和强度的材料组合，兼具顾强度和韧性，可以兼顾内部和外部环境，装载效果好，既能保证强度，又能保护电芯；节省原辅材料、重量轻、运输方便、密封性能好，符合环保绿色包装的要求；不需要大型的吸塑设备，节约成本，制作方便，外形美观，节省人力、提高效率。
为使本发明的目的、技术方案及优点更加清楚明白，以下将通过具体实施例和相关附图，对本发明作进一步详细说明。
