Description

超细纤维面料顶篷的包边方法 技术领域
本申请涉及汽车内饰件技术领域，例如涉及一种超细纤维面料顶篷的包边方法。
背景技术
随着汽车市场消费日益升级，以Alcantara(欧缔兰)为代表的麂皮绒(超细纤维)面料也逐渐由个别高端品牌开始在众多品牌车型上应用，并慢慢向中端市场普及。一直以来，在超细纤维类面料的包边过程中，因面料的延伸率太差，使用自动化设备包边时，面料易受力撕裂、拉断，而设备力太小则无法包紧，所以相关技术使用此种类面料的产品包边一直以人工为主，但人工手法不稳定，包边拉紧面料所需力量较大，不利于人员长时间作业，过程费时费力，生产效率低。
发明内容
本申请提供了一种超细纤维面料顶篷的包边方法，能够针对超细纤维类面料的缺陷，解决撕裂、拉断等包边不良问题，实现包边过程的自动化。
一实施例提供了一种超细纤维面料顶篷的包边方法，包括：在面料上沿着顶篷包边拐角形状加工出圆弧切口；将所述顶篷的面料正面朝下，对所述面料背面包边区域进行施胶，同时对包边拐角处使用雾化水喷淋，使表面被水雾浸透；及将所述顶篷及所述面料预贴合并放置于包边工位，并将随形机构的热压板压覆于所述包边面料上，其中，所述随性机构沿所述包边区域设置于所述包边工位上。
附图说明
图1是本申请一实施例提供的超细纤维面料顶篷的包边方法中圆弧切口的示意图；
图2是本申请一实施例提供的超细纤维面料顶篷的包边方法的流程图。
具体实施方式
在本申请的描述中，除非另有明确的规定和限定，术语“相连”、“连接”、“固定”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，可以是机械连接，也可以是电连接，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
在本申请的描述中，除非另有明确的规定和限定，第一特征在第二特征之“上”或之“下”可以包括第一特征和第二特征直接接触，也可以包括第一特征和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”包括第一特征在第二特征正下方和斜下方，或仅仅表示第一特征水平高度小于第二特征。下面结合附图并通过具体实施方式来进一步说明本申请的技术方案。
本实施例提供了一种超细纤维面料顶篷的包边方法，如图1-2所示，该方法包括：
S100：面料切割
在面料4上沿着顶篷包边拐角3的形状加工出圆弧切口，该圆弧切口均摊包边过程中受到的拉扯应力。
如图1所示，此处的圆弧切口包括圆孔部1和扩口部2，多个圆孔部1沿着顶篷包边拐角3的边缘间隔排布，扩口部2自圆孔部1向面料4边沿延伸，具体采用冲切或水切成型。
在一实施例中，圆孔部1的直径为6mm～15mm，圆孔部1的中心至顶篷包边拐角3的边沿的垂直距离为10mm～30mm，相邻圆弧切口的中心间距为8mm～16mm。
S200：施胶喷淋
将顶篷的面料正面朝下，对面料背面包边区域进行施胶，同时对包边拐角处使用雾化水喷淋，使表面被水雾浸透。
施胶喷淋过程中，将顶篷面料放置于施胶工位上，施胶工位上对应包边区域设置有多个雾化喷头，喷淋软化水，以保证面料表面湿度。在一实施例中，喷淋水量为每平方米5g～200g。
S300：加热包边
将顶篷及面料预贴合并放置于包边工位，包边工位上沿着包边区域设置有 随形机构，随形机构包括热压板，热压板压覆于包边面料上，压合的同时进行热传导，保证面料的延伸率。
在一实施例中，加热包边过程中，将面料加热至70℃～100℃，面料表面纤维因高湿状态不被破坏，且水分使热能迅速进入纤维内部，实现高效热传导。
综上，上述的超细纤维面料顶篷的包边方法在常规包边前进行特定造型切口的切割，并对包边区域进行雾化水喷淋、加热，以均匀分摊应力，改善面料物性，实现了稳定、有效的包边，便于机械自动化操作。
本申请提供的超细纤维面料顶篷的包边方法具有以下特点：
(1)利用超细纤维类面料在高温条件下延伸率较常温条件下有很大改善的特性，在包边过程中对面料进行加热，以改善面料的特性，使面料易于加工；
(2)利用圆弧切口能够分散受力的特性，对顶篷包边区域进行特定形状的切割，以增加面料耐拉伸性；
(3)利用面料高湿状态下导热速率更高，且不易烫伤表面绒毛的特性，在生产过程中对面料进行雾化水喷淋，保证超细纤维面料表面湿度；
(4)针对面料特性，提升面料的可加工性，使面料能够应用于自动化设备生产，减少人力投入。
