Abstract

A method for joining two components is disclosed. In an embodiment of the method, a joining element is inserted into the two components, and during the joining process, at least one parameter quantifying the joining process is determined. The joining element is inserted by a robot and the at least one parameter quantifying the joining process is determined by the robot. A device for joining two components is also disclosed.

First claim

The invention claimed is:

1. A method for joining two components, comprising the steps of:
inserting a joining element into the two components by a robot in a joining process;
measuring and evaluating a current consumption of drive axes of the robot:
determining parameters quantifying the joining process during the joining process by the robot, wherein the parameters are determined based on the measuring and evaluating of the current consumption and wherein the parameters include a force for driving in the joining element, an energy for driving in the joining element, an acceleration of the joining element, and a path of the joining element; and
monitoring and assessing the joining process and a joining connection produced by the joining process by the determined parameters.

2. The method according to claim 1 , further comprising the step of regulating the robot depending on the determined parameters.
