Description

用于向面式的基体上施加介质的方法和装置
技术领域
本发明涉及一种用于向面式的基体上、特别是向印刷电路板上施加介质的方法和装置。待施加的介质例如可以是粘结剂或焊膏。
背景技术
为了能够有效地给面式的基体设置介质、例如焊膏或粘接剂,在过去开发出了各种不同的方法,这些方法使得可以基本上同时地向印刷电路板的接近整个表面上施加所述介质。这里特别是所谓的丝网印刷法较为成功,在这种方法中可以借助于相应的印刷模板按相应希望的图案以简单的方式在基体上施加导体线路。
丝网印刷法构成一种将介质施加到基体上的经济的且有效的解决方案。但已经证明,通常在至少几个位置处,借助于丝网印刷法不能以足够令人满意的方式实现介质的施加。这特别是指这样的位置,所述位置与利用印刷模板可以实现的情况相比需要更多或更少的介质。
在这种情况下,介质的施加必须单独或点状地进行,其中为此通常使用所谓的且已知的分配器。借助于这种装置,尽管存在在印刷电路板的各单个位置按希望的量施加介质的可能性,但这种方法的效率要比前面所述的丝网印刷法低,因此,这种方法比较不适于常用地向印刷电路板上施加介质。如果设想,作为丝网印刷法的补充只是在几个确定的位置借助于分配器施加介质,则存在这样的问题,即,用于加工基体的相应的装置要设计得非常复杂。
发明内容
因此本发明的目的是,提供一种向基体上施加介质的改进的可能性。这里特别是应开创这样的可能性,即,即使是借助于分配器进行介质的补充施加也可以以简单和有效的方式进行。
所述目的通过根据权利要求1的方法以及通过根据权利要求6的装置来实现。本发明有利的改进方案是各从属权利要求的内容。
原则上本发明基于这样的构思,即,除了常见的对基体的印刷以外,还应借助于一分配器补充地施加介质。这里尽可能有效地利用已经是印刷基体必需的装置,以便使得也可以借助于分配器进行补充的施加介质。这里特别设想,将印刷基体本来就需要的光学的监控装置用于保持分配器,以便使分配器相对于所述监控装置按固定的关系设置,借助于所述监控装置确保基体相对于印刷装置的布置和正确定向(对齐)。
特别是可以设想,所述分配器固定在一照相机上,借助于该照相机可以在印刷方法的范围内监控标志,借助于所述标志确定基体的正确布置和定向。现在可以利用本来已经存在的照相机轴(线),一别借助于分配器例如在印刷电路板上放置粘结剂或焊料。这里分配器可以完全利用照相机轴的移动范围,以便到达全部待补充分配的位置。
因此,通过根据本发明的解决方案,明显地降低了总费用,因为不需要单独的用于借助于分配器施加介质的装置。此外,还可以利用所述照相机来确保分配器以正确的方式设置。以这种途径最终可以整体上提高在施加介质中的质量或精度。
附图说明
下面应根据附图对本发明进行详细说明。其中:
图1示出根据本发明的用于向面式的基体施加介质的装置的视图;
图2示出图1的视图的放大的局部。
具体实施方式
图1示出整体上用附图标记1表示的装置,借助于该装置可以将介质、例如粘结剂或焊膏施加到面式的基体上。这里示意性示出的基体2是一印刷电路板,该印刷电路板特别是应设有导体线路。
根据本发明设想,在一第一步骤中首先按照一种丝网印刷法施加待施加的介质的大部分。为此,示意性地示出一丝网印刷模板3,该丝网印刷模板此时为了以后的印刷工艺可以设置在印刷电路板2的表面上。这里重要的是,模板3相对于基体2以正确的方式设置和定向。
模板3相对于基体2的设置和定向借助于一光学的监控装置按已知的方式监控,该监控装置的主要组成部件是一照相机5。如图2中的放大视图所示,在照相机5的壳体6的上侧上设有一照相机窗口7,借助于该照相机窗口,可以观察位于照相机上方的印刷模板3。以相同的方式在壳体6的下侧上设有一第二照相机窗口,该照相机窗口用于,可以对位于照相机下方的印刷电路板2进行光学扫描。此时,借助于所述连个照相机窗口可以检测到设置在模板3上或印刷电路板2上的标志,通过所述标志可以识别,印刷电路板2是否正确地设置或定向,或者必要时是否需要相应的校正。在通过监控装置确认正确的设置之后,此时使印刷模板3下降到印刷电路板2上,以便启动印刷过程。
根据本发明,此外在照相机壳体6上还借助于一夹紧件8设置一分配器10,借助于所述分配器可以在另一个方法步骤中点状地并且对前面所述的丝网印刷法补充地向印刷电路板2上施加介质。在所示实施例中,涉及一种本身已知的所谓螺旋分配器10,在该螺旋分配器的前端部上设有一指向下面的针11,借助于一马达13通过该针将位于一筒(Kartusche)12中的介质施加到印刷电路板2上。例如可以在筒12中容纳粘结剂或焊膏。
根据本发明的解决方案的特别之处在于,分配器10固定地设置在照相机5上。这里由此得到第一个优点,即,照相机5的通过在图1中示出的各种不同的并且本身已知的部件实现的可移动性也可以用于相应地设置分配器10。分配器10由此可以在印刷电路板2的平面内在照相机5的运动范围内移动,而不必为此需要附加的机构。用于实现用于借助于丝网印刷法以及借助于分配器施加介质的组合式装置的费用可以以这种途径明显地降低。
另一个优点在于,分配器10按已知的相对于照相机5、具体地讲是相对于照相机窗口的布置形式设置。这意味着,在以后借助于分配器10补充施加介质时,照相机5也可以用于确保,分配器10以正确的方式定位。以这种途径,在施加介质时可以进一步改善精度。
因此,通过根据本发明的组合有助于实现精确地以及正确地将介质施加到基体上。同时还降低了用于实现相应装置的费用。
