Abstract (en)
The method for hardening an adhesive (3'), which is arranged on a first component (1') and a second component (2') to be adhered with the first component, by application of adhesive with a radiation (20), comprises influencing a part of the radiation directed in the direction of the adhesive in such a way that the part strikes on the selected area of the adhesive. The part of the radiation is blocked or diverted. A complete application of the adhesive with the radiation is carried out with a further irradiation process. The method for hardening an adhesive (3'), which is arranged on a first component (1') and on a second component (2') to be adhered with the first component, by application of adhesive with a radiation (20), comprises influencing a part of the radiation directed in the direction of the adhesive in such a way that the part strikes on the selected area of the adhesive. The part of the radiation is blocked or diverted. The ratio of the area and/or the surface on which the radiation is not striked on the basis of blockage or diversion on the available adhesive is selected to the area and/or the surface on which the radiation is striked on the available adhesive, in such a way that the adhesive volume not stopping the radiation is slightly greater than the shrink volume of the hardened adhesive. A complete application of the adhesive with the radiation is carried out with a further irradiation process. The adhesive is applied as layer between the components to be adhered, and a flat, radiopaque mask is used as means for partial blockage of the beam, where the mask is equipped with a radiation permeable area and is positioned between the radiation source and the component to be adhered. The radiation is UV-radiation and the adhesive is UV-curable adhesive. An independent claim is included for a microfluidic system.
Abstract (de)
Die Erfindung betrifft ein Verfahren zur Aushärtung eines Klebstoffs (3), welcher an wenigstens einem ersten Bauteil (1) und an wenigstens einem mit dem ersten Bauteil (1) zu verklebenden zweiten Bauteil (2) angeordnet ist, wobei die Aushärtung durch Beaufschlagung des Klebstoffs (3) mit einer Strahlung (4) eingeleitet wird. Erfindungsgemäß ist vorgesehen, dass ein Teil der in Richtung auf den Klebstoff (3) gerichteten Strahlung (4) derart beeinflusst wird, dass diese nicht (50) auf den Klebstoff (3), zumindest jedoch lediglich auf einen ausgewählten Bereich (51) des Klebstoffs auftrifft. Auf diese Weise ist es möglich, in gezielten (definierten) Bereichen des Klebstoffs (3) Hohlräume (6) zu erzeugen und somit eine gewünschte Veränderung bzw. Kontrolle der technischen Eigenschaften (bspw. Haftung, Festigkeit) der verklebten Baugruppe zu erreichen. Die Erfindung betrifft ferner noch spezielle Verwendungen des Verfahrens sowie mikrofluidische Systeme, welche insbesondere durch das erfindungsgemäße Verfahren hergestellt sind.
