Process for joining a foil or a membrane

摘要

Process for joining a foil or a membrane.;The invention relates to a method for joining at least one foil-like or membrane-like part to a structural part (9), wherein the foil-like or membrane-like part is separated by means of a tool (2) from a semi-finished product (3) and is held on the tool (2) by applying a reduced pressure, and wherein the foil-like or membrane-like part is placed on the structural part (9), and is in turn held on this (9) and joined to this (9) by applying a reduced pressure.;By means of the method a precise, reliable and readily automatable joining of a foil-like or membrane-like part to a structural part (9) is possible.;A device (1) is also proposed, with which the method according to the invention can readily be carried out.

1. A method for joining at least one foil-like or membrane-like part (3′) to a microfluidic structural part (9,9′) wherein the foil-like or membrane-like part (3′) is held on a semi-finished product (3) which comprises the steps of:
(a) separating the foil-like or membrane-like part (3′) from the semi-finished product (3) by means of a separation tool (2) wherein the foil-like or membrane-like part (3′) is held on the separation tool (2) by means of a partial vacuum or reduced pressure; (b) transferring the foil-like or membrane like part (3′) to an alignment component (8); (c) holding the foil-like or membrane-like part (3′) to the alignment component (8) by application of a second partial vacuum or reduced pressure; (d) positioning the foil-like or membrane like part (3′) that is held on the alignment component (8) in position for alignment and centering on the microfluidic structural part (9,9′); and (f) joining the foil-like or membrane-like part (3′) to the microfluidic structural part (9,9′), wherein said microfluidic structural part contains at least one micro-channel or at least one micro-chamber.
