本实用新型涉及用于在第一接触面和至少一个另外的接触面之间建立线连接的设备。本实用新型还涉及具有这种线连接的器件装置。
背景技术
用于建立线连接的设备是长期已知的，尤其以名称“线键合机”已知。通常，该设备构成为，使得，例如从US8,657,181B2中已知：通过线引导工具，实现将在线引导毛细管中引导的线的接触端部相对于要相互连接的接触面定位以及建立在线和接触面之间的连接。
为了建立连接，对线引导工具的冲头状构成的、通常也称作为“楔形件”的部件加载超声，使得设置在“楔形件”和接触表面之间的线通过在摩擦焊接过程中进行超声加载与接触面连接。
该焊接过程的执行，除了“楔形件”的超声加载之外，以线的足够的压力加载为前提，使得所述线必须借助相应的压力朝接触面挤压，所述楔形件由于超声加载执行平行于接触面的震荡振动。从这种类型的加载中得出接触表面的和设有该接触表面的组件的相应的机械负荷。
从上述内容中清楚的是：借助于超声键合来建立线连接的前提是相应的机械负荷能力还有接触部位的可触及性。因此，超声键合通常也在如下情况下使用，在所述情况下在专业术语方面也作为印刷电路板已知的、可承受机械负荷的电路板上制造具有可容易触及的接触面的线。
实用新型内容
本实用新型所基于的目的是：即使在存在接触部位的差的可触及性的情况下也能够实现在接触部之间建立线连接，或者也能够在线和接触部或接触体之间建立电接触，所述电接触部不应承受机械负荷。此外，本实用新型所基于的目的是：利用这样建立的线连接实现器件装置。
已知的线引导工具不仅用于将要与接触面接触的线定位而且用于通过线的超声加载在线和接触面之间建立机械接触，与已知的构成为线键合机的线引导工具不同，根据本实用新型使用如下线引导工具，所述线引导工具仅用于将线相对于接触部定位，然而不用于在线和接触部之间建立接触连接。更确切地说，导电的和机械保持的连接的建立借助于用至少部分熔化的、由焊料成形件形成的第一焊料量润湿在第一接触面和接触端部之间构成的接触区域，以构成第一焊料连接部，使得构成在接触端部和第一接触面之间的机械的、导电的连接。
随后，将线引导工具朝另外的接触面移动，使得在借助于线引导工具的移动在第一接触面和另外的接触面之间构成的线段的线段端部和第二接触面之间构成接触区域。
接着，进行借助至少部分熔化的、由焊料成形件形成的第二焊料量润湿另外的接触区域，以构成另外的焊料连接部，使得在线段端部和另外的接触面之间构成机械的、导电的连接。
随后，能够将线段与借助线引导工具引导的线分离。所述分离能够机械地或例如也热学地借助于对有意的分离部位进行激光加载来进行。
根据本实用新型对借助于线引导工具，将线相对于接触面定位连同构成接触区域；和与线引导工具无关地，借助于用焊料润湿接触面来在线和接触面之间建立导电的且机械的接触之间进行区别造成的结果是：应与线连接的接触面不受机械负荷。由于借助于润湿建立线和接触面之间的线连接，那么尤其也能够将多芯的线或还有压力敏感的线或导体、即尤其导电覆层的光导纤维与接触面连接。
除了由此避免在接触部上的力作用进而也能将特别压力敏感的接触部与线电连接之外，接触部的基本上平坦的表面构成也不是必要的，如该平坦的表面构成是对于执行超声键合重要的。因此，例如也能够在线和拱起的或完全球形的接触表面之间进行接触。
特别地，也能够执行串联接触或并联接触，其中将多个接触面与连续构成的线导体连接。
尤其有利的是：通过如下方式进行第一接触区域和第二接触区域的润湿：即焊料成形件距接触区域一定间距地设置在初始位置中，至少部分地熔化在初始位置中的焊料成形件，并且将至少部分熔化的焊料成形件从初始位置中朝接触区域离心分离。借此，也能够用焊料润湿在接触面和线之间构成的这种接触区域，所述接触区域不可借助用于在接触区域中喷涂焊料的机械的转移装置触及。更确切地说可行的是：从与接触区域间隔开的初始位置中起进行润湿。
尤其有利的是：为了限定初始位置，将焊料成形件在喷涂毛细管的喷嘴中设置在喷嘴的输出开口之上，其中输出开口的直径小于焊料成形件的直径，通过对焊料成形件加载激光能量来进行焊料成形件的熔化，并且通过对焊料成形件进行气体压力加载来进行熔化的焊料成形件的输出。
用于加载成形件的激光装置优选也能够用作为分离装置或也用于：在润湿设置在接触面上的线之前移除线的绝缘部，使得也能够将绝缘的线用于执行该方法。
根据本实用新型的设备包括：线引导工具，其用于将线的接触端部相对于第一接触面定位和在第一接触面和至少一个另外的接触面之间构成线段以及用于将线段端部相对于另外的接触面定位；和焊料喷涂装置，其用于将至少部分熔化的焊料成形件喷涂在接触端部和第一接触面之间构成的接触区域中和喷涂在线段端部和另外的接触面之间构成的接触区域中。
优选地，该设备具有用于分离所述线段的分离装置。
优选地，焊料喷涂装置独立于线引导工具构成，使得能够独立于线引导工具进行喷涂装置的定位，即例如能够在线引导工具的彼此跟随的接触位置中进行喷涂装置的定位，能够从不同的初始位置进行喷涂焊料成形件，所述初始位置实现接触区域的分别最佳的可润湿性。
如果线引导工具具有线引导毛细管，其用于输出借助于进给装置从在线引导毛细管的喷嘴处构成的输出开口中运送出的线，那么得到从输出开口中伸出的接触端部相对于要接触的接触面的精确的定位。
优选地，分离装置至少部分地通过线引导毛细管的喷嘴形成，使得喷嘴同时实现多个功能。
优选地，分离装置具有分离元件，所述分离元件相对于线引导毛细管的喷嘴能移动地构成，使得在分离元件构成为分离装置的第一刀刃的情况下，线引导毛细管的喷嘴能够构成配合刃(Gegenschneide)。
优选地，线引导毛细管经由所述线引导工具的基体刚性地与线压紧装置连接，所述线压紧装置通过设有分离元件的间隙与线引导毛细管的喷嘴间隔开。由此，设有多重功能的线引导工具的尤其紧凑的设计方案是可行的。
根据本实用新型的器件装置具有多个尤其构成为芯片的电子器件，其中所述器件以堆叠布置设置，并且设置在器件的连接侧上的接触面借助根据本实用新型所制造的线连接彼此连接，使得在第一焊料连接部和第二焊料连接部之间构成线段，所述第一焊料连接部将第一器件的第一接触面与线的接触端部连接，而所述第二焊料连接部将另外的器件的第二接触面与线连接。
在第一有利的实施方式中，器件构成金字塔形的堆叠布置，使得在两个彼此上下设置的器件的后侧和连接侧之间构成器件连接，并且构成用于将器件的接触面连接的线段阶梯式地在器件的相邻的侧边缘之上延伸。
在器件装置的另一有利的实施方式中，在两个彼此上下设置的器件的朝向彼此的后侧之间构成器件连接，并且构成用于将器件的接触面连接的线段弧形地在器件的相邻的侧边缘之上延伸。

具体实施方式
图1示出接触插头11的碗形构成的壳体部件10的示意图，其中在壳体部件10中在前侧12上、即在朝向在此未示出的、设置用于与接触插头11组合的接触插座的一侧上设有多个接触管脚13，为了简化图示在此仅示出所述接触管脚中的一个接触管脚13。
接触管脚13在其后部的、设置在壳体部件10之内的连接部件14上具有在此通过削平部形成的接触面15。在接触面15上方或右方存在线连接设备16，所述线连接设备包括线引导工具17以及焊料喷涂装置18。
线引导工具17具有线引导毛细管19以及经由基体20与线引导毛细管19连接的压紧装置21。在压紧装置21和线引导毛细管19之间构成的间隙22中容纳有在此构成为具有切割棱边24的刀刃的分离元件23。
线引导毛细管19具有喷嘴25，所述喷嘴与输出开口26相邻地设有配合刃棱边27，所述配合刃棱边连同设有切割棱边24的分离元件23一起构成分离装置28。
为了实现线引导工具17的多轴运动，基体20设有耦联装置29，所述耦联装置实现线引导工具17与机械手装置的未详细示出的手轴连接。
焊料喷涂装置18具有喷涂毛细管30，所述喷涂毛细管具有喷嘴31，所述喷嘴设有输出开口32。为了作用于在输出开口32之上容纳在喷嘴31中的焊料成形件33，焊料喷涂装置18设有在此未详细示出的沿着喷涂毛细管30的通道轴线34发射激光辐射的激光装置。焊料喷涂装置18同样能够如线引导工具17那样连接在用于实施多轴运动的机械手装置的手轴上。
线引导工具17和焊料喷涂装置18分别设有在此未详细示出的输送装置，所述输送装置在线引导工具17的情况下具有在此未详细示出的进给装置，借助所述进给装置将沿着线引导毛细管19引导的线35沿通道轴线36的方向向前移动并且在此从同样未详细示出的线储存卷中开卷。
在焊料喷涂装置18的情况下，输送装置设有用于容纳焊料成形件33的储备容器，所述焊料成形件借助于输送装置分别地从焊料容器中取出并且为了喷涂焊料成形件33而运送到图1中示出的初始位置P中。
图1中示出的配置示出直接在构成在线35的接触端部37和接触管脚13的接触面15之间建立的焊料连接部38之后的线连接设备16。
为了建立图1中示出的焊料连接部38，将从线引导毛细管19中引出的接触端部37定位，以在接触面15上构成接触区域39。在此，线35引导穿过压紧装置21的在当前情况下向下敞开的容纳槽40。如果接触端部37处于图1中示出的接触位置中，那么进行至少部分地熔化容纳在喷涂毛细管30的喷嘴31中的焊料成形件33，使得借助于对焊料成形件33进行气体压力加载，将焊料成形件33通过输出开口32排出并且朝接触区域39离心分离，其中所述焊料成形件33的直径d在至少部分熔化之前大于输出开口32的直径D。由于至少部分熔化的焊料成形件33碰撞到接触区域39上，得到接触区域的图1中示出的润湿。
在建立图1中示出的焊料连接部38之后，进行将线引导工具17的基体20或线引导工具17移动到图2中示出的第二接触位置中，其中由于将线35的接触端部37机械固定在接触管脚13上，在线引导工具17的线引导毛细管19的喷嘴25和接触管脚13之间构成线段41，使得在线段端部45和容纳在壳体部件10中的电路板43的接触面42之间构成另外的接触区域44，在所述另外的接触区域中，线35以线段端部45安置于接触面42上。
为了借助接触区域44的构成来辅助将连接区域45安置或贴靠在接触面42上，在当前的情况下，基体20围绕横轴线46枢转，使得压紧装置21从现在开始引起在线段35的走向中的轻微的弯曲。
随后，在线引导工具17的图2中示出的接触位置中，焊料喷涂装置18以上面已经阐述的方式和方法工作，使得从现在开始为了构成焊料连接部48将另外的焊料成形件33朝接触区域44离心分离，以构成接触区域44的润湿。
随后，通过刀刃23的轴向的切割运动49进行线段41的分开，其中线35被切断。
在图3至5中示出线连接设备50的另一实施方式，所述线连接设备与图1和2中示出的线连接设备16不同具有线引导工具51和分离装置52的装置，使得在当前情况下与焊料喷涂装置18相同构成的进而在此设有相同附图标记的焊料喷涂装置18设置在构成在线引导工具51和分离装置52之间的间隙62中。
特别地，图3至5中示出的线连接设备的分离装置52、线引导工具51和焊料喷涂装置18在需要时能够多轴地且尤其与彼此独立地以可在空间中移动的方式构成，以便能够将在空间中不同定向的接触面彼此连接。
线引导工具51具有在当前情况下竖直定向的线引导毛细管54，所述线引导毛细管在其自由端部处设有弯曲的喷嘴55，所述喷嘴具有输出开口56。如从图3可见，线引导毛细管54在基本上竖直设置的情况下实现将线35的接触端部37对准接触面15，使得接触端部37与接触面15重叠地设置并且同时与通过焊料喷涂装置18的通道轴线34限定的喷涂轴线相交。在该配置中，如上面参考图1已阐述那样，能够将至少部分熔化的焊料成形件33喷涂到接触面15上。
在接触端部37和接触面15之间建立第一焊料连接部38之后，为了构成线段41，同样如已经参考图1和2所描述那样，将线引导工具51移动到图4中示出的第二接触位置中，使得在另外的接触面42和线段端部45之间构成另外的接触区域44，在所述另外的接触区域中线以线段端部45安置在接触面42上。
在线引导工具51的图4中示出的接触位置中，为了构成另外的焊料连接部48，进行将另外的至少部分熔化的焊料成形件33朝接触区域44喷涂，使得将接触区域44和线35润湿。对于另外的焊料连接部48是最后由多个在持续地从线引导工具51的喷嘴55中引导的线35和接触面之间建立的焊料连接部的情况，随后通过分离装置52的切割运动53进行线段的分离，使得在分离装置59的分离元件60处构成的切割棱边61如在图5中示出那样将线35切断。
图6示出器件装置70，其具有三个在此构成为芯片的器件71、72、73，所述器件彼此上下重叠以金字塔形的堆叠布置设置。为了将器件71、72、73相互上下固定，在相邻的器件中在设有接触面75、76、77的连接侧83和后侧84之间设有在此通过填充不足构成的器件连接部85。
器件装置70具有优选利用图3至5中示出的线连接设备50建立的线连接，其中分别设置在连接侧83的侧边缘上的接触面75、76、77经由线段78彼此连接，使得在构成线段78的线79和接触面75、76、77之间分别构成焊料连接部80、81和82。
图7示出同样优选借助线连接装置50制造的器件装置90，所述器件装置具有两个在此同样构成为芯片的器件91、92，所述器件经由其后侧93、94彼此连接，使得器件91、92的连接侧95、96分别构成器件装置90的外侧，所述器件在当前的情况下分别设有两个接触面97、98。为了将各两个彼此关联的、设在彼此背离的连接侧95、96上的接触面97、98连接，所述连接面经由线段99彼此连接，使得构成线段99的线101经由构成在具有接触面97的下部的连接侧95上的第一焊料连接部102和经由借助设置在上部的接触侧94上的接触面96构成的第二焊料连接部103构成器件91、92之间的线连接。
