Abstract
An adhesive joining device for providing a connection between a metal surface and a body using an electrochemical etching device. The device has a vacuum holder to form a vacuum connection between the adhesive joining device and the metal surface. A tool changing holder receives at least two different tools in a time-staggered manner. A first tool can be an electrochemical etching cell for an electrolyte with an etching chamber which is oriented towards the metal surface, a feed for electrolyte, a drain, and two electrodes, one electrode being mechanically and electrically connected to the metal surface and the second electrode coming into contact with the electrolyte. A second tool is for holding and positioning the body to be adhered to the etched metal surface. The distance, position, alignment, and/or parallelity of the body to be adhered can be configured in a reliable and defined manner for the adhesion process.
