<p>The method involves producing a screw connection by a screwing tool i.e. power screwdriver (12). Objects e.g. bolt (22) and work-piece (24), to be screwed is identified by an optical image processing. A characteristic of the objects to be screwed or a characteristic in the proximity of the objects is evaluated. A coding i.e. data-matrix code, on the objects or in the proximity of the objects is evaluated. Electromagnetic radiation in a visible region and a non-visible region is evaluated. The coding of the objects is realized after illumination with UV light. An independent claim is also included for a screwing device.</p> |
