Description

汽车灯的制造方法以及相应的汽车灯
技术领域
本发明涉及汽车灯的制造方法以及使用所述方法所获得的相应汽车灯。
背景技术
术语汽车灯理解成是指一般性的后汽车灯或前汽车灯，后者也被称为前灯。
如已知的那样，汽车灯是下述车辆的照明和/或信号装置，所述车辆包括具有朝向车辆外部的照明和/或信号功能的至少一个外部汽车灯，诸如像侧光灯、指示灯、刹车灯、后雾灯、倒车灯、近光灯、远光大灯等。
汽车灯以其最简单的形式包括容纳体、透镜体和至少一个光源。
透镜体放置成封闭容纳体的口部以便形成一个壳体腔室。光源布置于壳体腔室内部，所述光源可被定向以便当供以电力时朝向透镜体发射光。
一旦各个部件已被组装好，则汽车灯的制造方法必须设置成将透镜体附接和以气密的方式密封到容纳体。
这样的密封和附接通常通过焊接来执行。
自然地，焊接也会与更复杂汽车灯的例如布置于壳体腔室内部的其它部件相关。
现有技术的解决方案设置成使用各种技术进行焊接。从机械的角度出发，现有技术的焊接使得能够实现接头，它们随着时间的推移从机械的角度出发以及从密封的角度出发都是可靠的，从机械的角度出发考虑到汽车灯持续地经受连续的机械应力和热应力(振动以及大气条件)，而从密封的角度出发考虑到例如防止水或污物从外部朝向灯内部的任何渗透。
然而现有解决方案的组装技术具有缺陷，其原因在于透镜体到容纳体的焊接过程相当复杂、缓慢、以及因而是昂贵的。
例如，已知使用振动焊接技术来组装汽车灯。迄今为止，在汽车灯中的激光焊接应用连同目前使用的技术都不是很有效，因为需要将复杂的几何形状(诸如汽车灯的那些部件)焊接到一起。
事实上，汽车灯的透镜体和容纳体由聚合物材料制成并包括高度复杂的几何形状，所述几何形状具有弯曲的或笔直的联接表面，而所述联接表面具有沿着所述相互联接的整个周边的高度可变性。
此外，如已知的那样，聚合物主体的激光焊接过程在其最普遍的意义上采取热能的局部供给，能够局部地熔化聚合物主体，所述聚合物主体相应具有对激光源(诸如激光二极管)所发射的电磁辐射的良好透射率和良好吸收性。
更具体而言，由激光源所发射的电磁辐射的光能量在其被吸收到吸收性聚合物主体内的过程中转化为热量。从而吸收性聚合物主体局部熔化，并且同时在相应于接触主体之间界面区域的限定焊接区域内将热量传导到透射性聚合物主体。软化的聚合物主体因此可互相渗透，一旦冷却就永久性地连接。
在前灯中，聚合物主体例如包括汽车灯的透镜体和容纳体，其中所述透镜体用作透射性的聚合物主体，而容纳体用作吸收性的聚合物主体。
然而，汽车灯或其诸如容纳体和透镜体的部件的复杂几何形状不适用于当前的激光焊接技术，这些技术实际上优化成适于应用到平坦的壁、简单的几何形状和相对薄厚度的主体上。
由此可见，激光焊接技术目前很少用于汽车灯上，因为它们并不能确保令人满意的结果，并且在任何情况下使用替代性的焊接技术都不具有竞争力的成本/时间。
因此存在汽车灯的另外一个特点，其使得目前的激光焊接技术复杂化、形成进一步的障碍且使其不便利。
实际上，汽车灯的部件(例如透镜体)可由光源所发射的光穿过，从而实现汽车灯的照明。因此透镜体可采取着色，这将根据规定所要求的颜色赋予给由光源所发射的光。例如，汽车灯的停车灯可用基本白色的光源来实现，而透镜体趋向于红色。
然而，例如在激光焊接过程中，着色的透镜体(例如趋向于红色)与无色的透镜体相比会吸收大量的光能，这有损于由激光源所提供的光能，因而激光源必须能够在焊接区域内提供预定的光能。由于着色透镜体造成的吸收性增加需要使用更高功率的激光束，从而具有高的消耗和焊接成本，其中着色透镜体作为透射性元件用来过滤所发射的辐射。
鉴于所有的上述考虑，激光焊接技术迄今为止很少使用在汽车灯上，因为它们与替代性的焊接技术(诸如像摩擦焊接)相比太复杂和昂贵以及不方便设计。
发明内容
本发明的目的在于设计出一种在汽车灯中使用的用于聚合物主体的激光焊接方法，与由现有技术所提供的功率相比其能够减小激光源的功率。
因此本发明的目的在于通过激光焊接技术来执行汽车灯的焊接，所述激光焊接技术克服了有关汽车灯特定性质的技术缺陷，上述缺陷迄今为止使得这种焊接技术不便利且昂贵。
该目的通过根据权利要求1所述的汽车灯的制造方法以及通过根据权利要求6所述的汽车灯来实现。
本发明的其它实施例在从属权利要求中描述。

具体实施方式
参照前述附图，附图标记4指示整个汽车灯，其中下面的描述是指以不丧失其一般性应用的方式来进行描述。
如上所述，术语汽车灯理解成是指一般性的后汽车灯或前汽车灯，后者也被称为前灯。
如已知的那样，汽车灯包括具有照明和/或信号功能的至少一个外部汽车灯，诸如像侧光灯(其可以是前侧、后侧或侧面侧光灯)、指示灯、刹车灯、后雾灯、近光灯、远光大灯等。
汽车灯4包括通常为聚合物材料的容纳体8，其通常允许将汽车灯4附接到相应的车辆上。
对于本发明的目的而言，容纳体8可以是任何形状和尺寸，并且甚至可以是汽车灯内部的元件，例如其不直接与相关联车辆的例如车身或其它紧固件相关联。
根据一个实施例，容纳体8限定容纳壳体12，其容纳至少一个光源16，所述光源电连接到以便对其供电的电连接器件，并适于发射光束以便传播到汽车灯的外部。对于本发明的目的而言，与所使用的光源16的类型是无关的；优选地，光源16是发光二极管(LED)光源。
容纳体8由第一周边轮廓20界定。
透镜体24结合到容纳体8，所述透镜体依次由第二周边轮廓28界定。
对于本发明的目的而言，透镜体24可在汽车灯4的外部，从而限定汽车灯的直接经受环境的至少一个外壁；对于本发明的目的而言，透镜体也可在汽车灯4的内部，即不直接经受外部环境，进而由一个或多个屏或覆盖板直接或间接地覆盖。
根据一个可能的实施例，透镜体24适于封闭容纳壳体12并适于将由光源16所产生的光束透射到汽车灯4的外部。
为此目的，所述透镜体24由至少部分透明的或半透明的或透明的材料制成，并且还可包括一个或多个不透明的部分，以便允许在任何情况下由光源16所产生的光束至少部分地穿过。
第二周边轮廓28相对于第一周边轮廓20是对应形状的，以便根据带形状的联接而在汽车灯4的组装配置中与后者即第一周边轮廓20联接。
汽车灯4的组装包括将相应的第一和第二周边轮廓20，28至少部分地结合到彼此的步骤。例如，所述步骤设置成将透镜体24布置成封闭容纳体8的容纳壳体12，以便将相应的第一和第二周边轮廓20，28结合。
有利地，根据本发明的汽车灯的制造方法设置成通过激光焊接，对应于所述周边轮廓20，28将所述透镜体和容纳体结合到彼此。
激光焊接过程可通过不同的技术实现，例如，通过同步激光焊接，几乎同步的激光焊接，边界激光焊接，掩模激光焊接，径向激光焊接，整体激光焊接等。
然而，在下面的描述中，将具体参照同步激光焊接，但以不丧失其一般性应用的方式来进行描述。
具体地，提供至少一个激光源(未示出)，以便其发射具有特征发射光谱的激光束或光束或电磁辐射。采用特征发射光谱指基本上在某一频率下发射的或具有一定波长的电磁辐射。根据一个实施例，所述激光源为发射激光束的激光二极管。根据可能的另一实施例，激光源包括CO2激光器或YAG激光器，在CO2激光器中激光束由包含CO2的气体混合物产生，而在YAG激光器中激光束由固态晶体产生。
所述激光源发射的光束可直接被发送到透镜体24；在一个优选的实施例中，激光源与插入到基体/光导33内的光纤32相关联，所述基体/光导33具有支撑光纤32以及引导由激光源所发射光束的功能。
优选在将容纳体8放置到相应的附接块35内之后进行焊接。
有利地，提供透镜体24的步骤设想到所述透镜体24通过模制技术获得，以便具有包括至少第一和第二层36、40的透镜体24，所述第一和第二层36、40至少部分地彼此重叠并且集成到彼此。
根据一个可能的实施例，第一层36朝向汽车灯4的外部以及第二层40朝向容纳壳体12。
除了所述层的相互定位之外，所述层36、40有利地具有相对于激光源发射光谱的不同透射率值。
换言之，所述层36、40具有不同的光学特性，使得它们显示出相应于激光源的特征发射光谱的不同透射率值。因此，由激光源发射的光束将由两层36、40不同地透射或吸收。
具体地，透镜体24到容纳体8的焊接是激光焊接，其中由激光二极管所发射的光束朝向周边轮廓20、28发送(route)，以便在通过透镜体24的至少一层36、40之后到达容纳体8的所述第一周边轮廓20，所述层36、40具有相对于发射光谱的不同透射率值。
在焊接步骤期间，容纳体8用作相对于由激光源所发射光束的吸收构件，以及透镜体24用作所述光束的透射构件。
根据一个实施例，由激光源所发射的光辐射在到达焊接区域之前穿过透镜体24的所述第一层36和第二层40，所述焊接区域位于第一和第二周边轮廓20、28之间的界面44处。
根据一个实施例，透镜体24的所述层36和40之一是为聚合物材料的层，其具有在激光源发射光谱上所测量的大于90％的透射率值。
例如，透镜体24的至少一个所述层36、40是由大致无色的材料制成的层。
根据一个实施例，至少一个所述层36、40由具有所需颜色的聚合物材料制成，所述层36、40具有的透射率足以不软化由光束所击中的材料并足以将光束朝向周边轮廓20、28和朝向界面44透射。
可以使得透镜体24的第一层36和第二层40由相同的材料制成。例如，透镜体24的第一和/或第二层36、40的材料是一种树脂，诸如PMMA，PC等。
根据优选的实施例，具有较大透射率值的透镜体24的层36或40的厚度大于具有较小透射率值的层36或40。
根据一个可能的实施例，透镜体24具有4.5毫米的总厚度，其中2毫米针对具有较小透射率值的层36或40以及另外2.5毫米针对具有较大透射率值的层40或36。
通过这种方式将具有更好的能量效率，因为对于相同的总路径而言(即必须由光束经过以便到达界面44的透镜体24的厚度)，，具有较低功率消耗和因此更高透射效率的光束的路径或路程增加。
对于本发明的目的而言，透镜体24的所述第一和第二层36、40通过共模制技术来获得。
例如，透镜体24通过多色注射模制技术来获得，其中使用设有模具的设备，所述模具包括固定平台和旋转平台，所述固定平台具有至少两个基体半模，而所述旋转平台具有冲头半模，所述旋转平台能够相对于固定平台移动，以便将冲头半模与存在于固定平台上的每个基体半模联接。
不管使用哪种具体模制技术，如所看到的那样，透镜体24具有：
集成到彼此并至少部分地重叠的至少两层36、40。
两个或多个层36、40优选制成不同的颜色：通常，其中一个层是无色的或基本上透明的，另一个层被着色，因为所述另一个层必须过滤由所述光源发射的光，使得从光输出中产生的光束具有所需的颜色；例如，针对侧光灯或停止灯为红色，针对指示灯为橙色等。着色(即掺杂材料以便获得透镜体的着色层)对于入射光束的相同光谱而言会改变透射率：在一般情况下，在没有掺杂的情况下即在存在无色层的情况下透射率增加，以及透射率随着所述掺杂的增加而减小。
如所看到的那样，对于汽车灯功能的目的而言，例如假设常用光源发射基本上白色的光束，所述透镜体24必须具有一个或多个着色件，使得输出的光束具有所需的颜色。
在现有技术的解决方案中，用激光技术焊接的透镜体具有在单件中的着色部分：换言之，透镜体由单一着色层构成，然后掺杂所需的颜色。这种解决方案在试图通过激光焊接方式来将透镜体24焊接到容纳体8时不是很有效。有利地，根据本发明，透镜体取而代之的是包括至少两层，所述至少两层用不同的掺杂进行着色，以便至少部分地增加所述透镜体的总透射率。这样的效果可通过下述来获得：将无色层(具有大于90％的透射率)施加到着色层(例如透射率小于90％的红色)来获得，或重叠两个均着色的层，以便提供所需颜色的光输出并具有优于相应单个着色层情况下的透镜体的总透射率。
根据一个实施例，透镜体24在第二周边轮廓28处包括与容纳体8接触的第二接触边缘48，其中所述第二接触边缘48遵循相应的第二周边轮廓28且从所述第二周边轮廓28在容纳体8的方向上突出。
通过这种方式，由激光源所发射的光辐射被定向，以便在所述第二接触边缘48内进行引导，并作用到容纳体8的第一周边轮廓20上。
根据一个实施例，第二接触边缘48与透镜体24的第二层40是一体的(或集成)。例如，透镜体24的第二层40是具有较高透射率的层，并且还包括所述第二接触边缘48：以这种方式，进一步增加在具有更高透射率的层内部的光束路径。
根据另一实施例，第二接触边缘48包括第一和第二层36、40的重叠部分(图6至图7)。
例如(图6)，所述重叠部分36'、40'包括第一层36的至少一个突起36'，其至少部分地深入到第二层40的第二接触边缘48内。
根据一种可能的焊接技术，由激光源所发射的光辐射在所述周边轮廓20、28处根据基本上垂直于透镜体的层36、40的方向定向(图5)。
根据另一实施例，所述透镜体24在第二周边轮廓28处包括朝向容纳体8的折叠部分52，折叠部分52与透镜体24是一体的并限定与容纳体8接触的第二接触边缘48；折叠部分52又包括透镜体24的第一层和第二层36、40的重叠部分(图6至图7)。
由激光源所发射的光辐射在第二接触边缘48处根据基本上平行于透镜体24的层36、40的方向定向。
在这种情况下，光辐射也被定向，以便沿着透镜体的每个层36、40将其自身引导到第二接触边缘48内，并作用到第一周边轮廓20上。
根据一个可能的实施例，容纳体8在第一周边轮廓20处包括与容纳体8接触的第一接触边缘56，所述第一接触边缘56遵循相应的第一周边轮廓20并且从其在透镜体24的方向上突出。
第一周边轮廓20相对于所述第二周边轮廓28是至少部分地对应形状的，以及第一周边轮廓20具有抵接壁60，其以抵接的方式接纳所述第二接触边缘56。
抵接壁60形成透镜体24和容纳体8之间的界面44。
优选地，所述抵接壁60具有的厚度大于或等于第二接触边缘48的相应支撑壁64。
如上所述，根据本发明的适于制造方法的激光焊接技术可以是各种类型的；例如，根据“同步”焊接技术，激光焊接步骤通过一个或多个光纤来执行，所述光纤同时将相应的光辐射发射到所述周边轮廓20，28的分开的预定部分上。
还可能的是，根据“边界”焊接技术也可通过至少一个移动激光源用相应的光纤32来执行激光焊接步骤，所述光纤32受到引导以便将光辐射沿着所述周边轮廓20、28进行定向。
如可从描述中理解到的那样，根据本发明的制造方法使得能够克服现有技术的缺陷。
具体地，由于本发明的方法，还能够将激光焊接技术应用于汽车灯上，所述汽车灯具有任何类型的复杂几何形状，具有沿着灯的周边高度变化的曲率和厚度。
相比于现有技术的替代性焊接技术，根据本发明的激光焊接技术不仅方便，而且在成本和时间方面可更好，且与汽车灯领域中现有技术的解决方案相比，焊接接头具有相同的质量。
具体地，由于至少两个层相对于激光源的发射光谱存在不同的透射率，因而可降低消耗且降低成本，同时光束的较大部分可透射到透镜体和容纳体之间的焊接界面上。
界面部分上的光束因此适于获得具有优异的机械质量、不浪费光功率的焊接接头。
此外，不管用何种技术来执行激光焊接步骤(例如“边界”或“同步”类型)，激光焊接步骤都是快速和可靠的，从而相比于现有技术针对相同质量的接头允许进一步降低组装成本。
此外，包括至少两层的透镜体的模制技术使得有可能获得与使用常规模制技术相比具有更大厚度的透镜体的周边轮廓和/或接触边缘。由于透镜体的周边轮廓以及相应接触边缘的厚度增加，可将光束的更大部分引导并透射到所述容纳体，以便获得焊接接头的更多加热的益处，因此由于更大的能效而实现节能。
此外，由于透镜体的周边轮廓和相应接触边缘的厚度增加，也有可能引导具有更高光输出的光束，以便例如在相对远离激光源发射器的界面区域(在透镜体和容纳体之间)内进行焊接，例如，对于具有透镜体的特定几何形状和特别明显的高度或厚度的汽车灯而言。
换言之，如果透镜体相对于所述界面表面特别向前或明显向外，光束在到达所述界面表面之前将必须覆盖相对长的路径，同时将激光源和相应的光纤放置在与透镜体的外表面相接触的界限处。在所述路径中，光束将至少部分地由所述透镜体所吸收，因而，为了在界面表面处局部熔化所述容器体(吸收性)，将需要发送高功率的光束。以这种方式，一方面将会增加消耗而另一风险是在透镜体的不同部分内产生不必要的熔化或软化。在其它情况下，存在所述透镜体的过于狭窄的周边轮廓和相应的接触边缘将导致在界面表面处的塑料材料不熔融，从而使得焊接不可能。
相反，由于实现透镜体的至少两层，所以能够创建具有足够厚度的轮廓和边缘，从而在提高的距离或深度处获得光束的有效透射，所述距离或深度即从透镜体的外表面到透镜体和容纳体之间的界面表面之间的距离，从而使得对于具有任何几何形状的汽车灯而言激光焊接是可能和有效的。
本领域内的技术人员可对上述的汽车灯的制造方法做出许多修改和变型，以满足相应的和特定的要求，同时仍处于如由以下权利要求所限定的本发明保护范围之内。
