本申请是要求于2015年6月26日提交的美国临时申请No.62/185,296的优先权的PCT国际专利申请。上述申请的公开内容通过参引并入本文。
技术领域
本发明涉及将热塑性复合材料部件焊接在一起从而具有复杂的三维焊缝的方法。
背景技术
用于汽车应用的电阻植入焊接碳纤维填充的热塑性复合材料组件由于碳纤维填料的导电性而产生挑战。这些问题已经通过使用高导电性网材料解决,所述高导电性网材料例如在2014年4月10日提交的题为RESISTIVE IMPLANT WELDING CARBON FIBERTHERMOPLASTICS USING HIGHLY CONDUCTIVE MESH(使用高导电性网的电阻植入焊接碳纤维热塑性材料)的USSN 61/978,042、现在的2015年4月6日提交的并公开为WO2015155669A1的国际申请号PCT/IB2015/052485的共同待审的申请中阐述,上述申请通过参引并入本文作为本发明的一部分。
尽管通过上述增强技术改进了现有技术,但是由于汽车面板升举门和前端模块等中通常使用的三维形状,使电阻植入焊接变得复杂。当表面的角部变得尖锐和/或表面本身复杂时,网扭曲到一定程度使得电阻植入焊接中的功能减小或引起故障。
因此,本领域需要提供一种将电阻植入焊接用于小角度和其他复杂三维表面的方法。
发明内容
一种电阻植入焊接热塑性复合材料的方法。复合材料部件包括沿着表面待焊接在一起的两个部件。在优选实施方式中,两个组件部件的至少一个部件由碳纤维材料形成。组件的两个部件各自具有焊接表面,组件沿着该焊接表面焊接在一起。焊接表面包括第一表面,第一表面以超过约30度的角度或另一三维形状邻接第二表面。第一丝网导体材料沿着第一表面定位在至少两个部件的焊接表面之间。第二丝网导体材料以重叠的方式通过成角度连接沿着第二表面定位在至少两个部件的焊接表面之间。将电流施加至导体使导体被加热并使组件的至少两个部件熔融在一起。当使用导电的可焊接材料比如碳纤维时,重叠的网状物材料的每个焊脚被通电以单独地沿着角度焊接,从而使穿过部件材料的电流的短路或分流最小化。
从下文提供的详细描述中,本发明的其他适用领域将变得明显。应当理解的是,在指示发明的优选实施方式的同时,详细描述和特定示例仅用于说明的目的,而并不意在限制本发明的范围。

具体实施方式
优选实施方式的以下描述本质上仅仅是示例性的,并决非意在对本发明、本发明的应用或用途进行限制。
总体参照图1,在拐角周围施加总体以100示出的丝网并弯曲丝网100的常规方法由于载体丝线102会彼此接触而不起作用,以至于电阻植入焊接中的功能减少或引起焊接故障。丝网100以大的弯曲角度形成的平行四边形将闭合或以其他方式显著地减少由网状织物产生的孔。一旦网夹在两个热塑性复合材料之间并且电压施加至网的相反的两个端部,上述结构将不允许熔融材料流过丝网。目前,焊接线限于45度的弯曲角度以确保由网状织物产生的孔仍然足够大从而允许熔融材料通过网状织物。图1示出了由“W”指示的丝网宽度,在该丝网宽度处网状织物开口或孔通常是正方形或适于接纳用于焊接的熔融材料的其他形状,并且图1示出了倾斜区域,该倾斜区域具有由“W’”指示的调整过的宽度,在该调整过的宽度处开口是通常将不允许用于焊接的熔融材料有效地流过丝线的平行四边形。
为了三维部件的较大的焊接灵活性,电阻植入焊接的常规方法受到丝网可以在平面内弯曲的量的限制。通常当使用标准的.009”直径的丝线编织成每英寸16×16丝线的网格密度时这个极限是45度。本发明使用交叉点来解决该弯曲极限。
总体参照图2至图6,根据本发明提供了一种电阻植入焊接热塑性复合材料的方法。总体以10示出的部件组装件具有至少第一部件12和第二部件14,第一部件12和第二部件14为可焊接的热塑性复合材料,优选地至少一个部件由碳纤维增强的热塑性复合材料形成,并且总体以10示出的部件组件设置有总体以16指示的多条丝网条,该丝网条在焊接期间沿着第一部件12和第二部件14的多个表面定位。丝网条相交。交叉点用作将单独的丝网条焊接成独立电路的内部接触点。这允许在贯穿部件10没有显著的电流损失的情况下使电流沿着丝网的更多线性路径被引导。
提供了总体以10示出的部件组件,该部件组件具有由可焊接的热塑性材料形成的组件的至少两个部件,至少第一部件12和第二部件14。优选地,部件12、14中的至少一者由碳纤维增强的热塑性复合材料形成。组件的第一部件12和第二部件14各自具有至少一个焊接表面,组件沿着所述至少一个焊接表面焊接在一起。焊接表面包括第一表面,第一表面以超过约30度的角度或另一三维形状邻接第二表面。第一丝网导体材料沿着第一表面定位在至少两个部件12、14的焊接表面之间。第二丝网导体材料沿着第二表面以重叠的方式通过成角度的连接定位在至少两个部件12、14的焊接表面之间。向导体施加电流使导体被加热并使组件的至少两个部件熔融在一起。
图3描绘了使用碳纤维增强的热塑性复合材料模制的第一部件12和第二部件14,以及需要焊接在一起的三个焊接表面或“边缘”(在图6中最佳示出的第一表面18、第二表面20和第三表面22)。第二表面20在第一交叉点24与第一表面18相交并且在第二交叉点26处与第三表面22相交。由焊接线产生的角度总共为270度。如上所述,在这些拐角周围施加丝网并弯曲丝网的常规方法是不可取的,这是因为七根载体丝线将彼此接触。参见图1。
为了实现比如图3中示出的期望的更大的弯曲角度,将单独一条丝网施加到270度的平面角度中的常规方法不是有效的。图2示出了实现任何所需的弯曲角度的方法。在弯曲角度小于45度的情况下通过沿着部件边缘施加丝网导体材料4例如丝网条,并且在公共交叉点6处堆叠新的丝网5,可以在交叉点6处以任何所需的量增加弯曲角度。类似地,可以在其他交叉点处施加附加的丝网条以进一步提高焊接的可设计性。为了确保交叉点6处堆叠的丝网的良好的电接触,探针7必须穿过总体以2示出的一个部件中的孔8并且探针7压靠堆叠的丝网6和总体以1示出的第二部件的壁坯(wall stock)9(参见图2)。
部件组件10的第一部件12或第二部件14中的至少一者具有至少一个孔和至少一个探针。图6示出了具有两个孔28、30和用于与丝网16接触的探针32的第二部件14,其中,为了清楚起见省略了丝网16。应当理解的是,在不脱离本发明的范围的情况下可以设想更多或更少的孔和探针(例如与孔30相邻的探针32的附加的探针镜像)。图5示出了组件10,其中,在交叉点24、26处堆叠丝网16以实现270度的焊缝角度。图3中示出的第一表面18、第二表面22和第三表面22现在可以作为如图4所示的单个电路焊接在一起。
在优选的实施方式中,将第一条丝网34施加至第一表面18,并且将第三条丝网38施加至第三表面22。将第二条丝网36施加至第二表面20并且在交叉点24、26处与第一条丝网34和第三条丝网38相交。替代性地,首先施加第二条丝网36,并且将第一条丝网34施加至第一表面18,将第三条丝网38施加至第三表面22,并且在交叉点24、26处将第一条丝网34和第三条丝网38放置在第二条丝网36的顶部上。替代性地,在每个交叉点24、26处施加附加的丝网。应当理解的是,根据应用,在不脱离本发明的范围的情况下,可以设想到更多或更少的交叉点、多种丝网导体材料和/或待焊接的边缘/表面。
第二部件14上的第一表面18、第二表面20和第三表面22中的每一者分别对应于第一部件12上的相对的第四表面40、第五表面42和第六表面44或“边缘”,其中,用于焊接的对应的第一条丝网34、第二条丝网36和第三条丝网38在所述表面之间。
进行导电复合材料的焊接的方法包括将每条丝网(例如34、36、38)分别地焊接成单独的电路,如图4所示。指示为“电路#1”的第一电路使用一组唯一的工艺参数并且使用交叉点探针作为电极和另一相邻电路端部作为相反的电极而被焊接。正负变化应用于电路#1,而其余电极与电压源断开连接。在焊接电路#1所需的必要电流已经完成之后,与指示为“电路#2”的第二电路直接相邻的电极以相反的极性被激活,而其余电极与电压源断开连接。电路#2也通过一组唯一的工艺参数被通电。指示为“电路#3”的第三电路重复该过程。
上述方法适用于不导电的复合材料。对于导电的复合材料,该方法将不起作用,除非网材料比复合材料更具导电性。现在参照图7,如果使用总体以200示出的具有标准的网材料202比如不锈钢的部件组件焊接与图4所示的类似的部件,则电流将分流穿过部件(如总体以箭头204指示)并产生不均匀的焊接。
在本发明的实施方式中,通过使用图4中描绘的方法,使用堆叠的丝网将不导电的热塑性塑料焊接成角度大于45度。所有三个电路通过将部件的右侧部处的电极连接且不使用内部连接件而一次焊接。
如在附图中容易理解的,该方法允许在共同交叉点处堆叠丝网以实现任何期望的弯曲角度。在一个部件中在共同交叉点处设置有孔,探针穿过该孔并压靠堆叠的丝网和另一部件的壁坯。这确保了探针正确地接触网以使网的电路通电。探针用于在网夹在层之间的点处接触网状物,或者在优选实施方式中,沿着交叉点设置孔以允许插入探针。在使用高导电性部件材料比如碳复合材料的优选实施方式中,该方法允许使用每条丝网作为独立的焊接电路来限制电流分流穿过导电复合材料部件。如本文中所阐述的,这是使用堆叠的丝网的相邻公共交叉点作为每个电路的电极来实现的。此外,在优选实施方式中,在复合部件的焊接中进行焊接过程时,沿着电路的其余电极断开连接以限制穿过部件的分流。根据复合材料是导电的并且网是高导电性网的一个实施方式,整个网在最外周边缘之间通电,以使整个网材料通电。在复合材料是不导电的另一实施方式中,网状导体材料中的每个网状导体材料的最外周端部可以由探针接触并且最外周边缘被通电以焊接部件。
此外,本发明的方法允许部件的阶梯形多层焊接,使得每个焊接电路可以使用唯一的工艺参数独立地通电,所述唯一的工艺参数允许沿着待焊接的接缝的每个焊脚进行定制的焊接。因此,可以针对电路的每个单独的焊脚处的部件的唯一形态调整焊接方法。这为针对部件设计的单独需求进行调整的焊接定制提供了改进的焊接结果、质量和增加的强度。
本发明的描述本质上仅仅是示例性的,并且因此,不脱离本发明主旨的变型意在被包括在本发明的范围内。这些变型不能被认为是脱离本发明的精神和范围。
