ADHESIVE JOINING DEVICE AND ADHESIVE JOINING METHOD FOR A METAL SURFACE

An adhesive joining device for providing and/or producing an adhesive connection in an adhesive point and/or adhesive section on a metal surface (5) to a body and/or component (4) to be adhered thereon and an adhesive using an electrochemical etching device, having a vacuum holder (1) with a vacuum connection (11), wherein a vacuum can be formed between the adhesive joining device and the metal surface (5) around the adhesive point and/or adhesive section to be produced; a tool changing holder (2) which receives at least two different tools (31, 32) in a time-staggered manner and in a defined position; a first usable tool (31) which can be inserted into the tool holder (2) in a time-staggered manner, namely an electrochemical etching cell for an electrolyte with an etching chamber which is oriented towards the metal surface (5), a feed for supplying an electrolyte (311) to the etching chamber, a drain for the etching chamber (312), and two electrodes (12, 313) with corresponding electric contacts, one electrode (12) being mechanically and electrically connected to the metal surface (5) to be structured and the second electrode (313) coming into contact with the electrolyte; and a second usable tool (32) which can be inserted into the tool holder (2) in a time-staggered manner for holding and positioning the body and/or component (4) to be adhered to the etched metal surface (5) with a defined position within the tool holder (2). The distance, position, alignment, and/or parallelity of the body (4) to be adhered can be configured in a reliable and defined manner for the adhesion process. Also, an adhesive joining method for a metal surface using the adhesive joining device.
