Abstract
The present invention relates to a method for connecting two joining elements, these elements being connected by means of a thermally activatable adhesive with a flat heating element arranged therein, by suitable heating of the adhesive. The invention also relates to an assembly produced in this way from two joining elements and to an arrangement designed for carrying out a corresponding method.
Claims13
A method for connecting two joining elements, comprising the steps of:
- a) providing the two joining elements,
- b) providing a thermally activatable adhesive,
- c) providing a flat heating element,
- d) embedding the flat heating element within the thermally activatable adhesive,
- e) arranging the flat heating element and the thermally activatable adhesive between the joining elements,
- f) heating the thermally activatable adhesive by applying electrical power to the flat heating element while at the same time measuring a temperature of the thermally activatable adhesive, the extent to which electrical power is applied to the flat heating element being controlled in dependence on the temperature measured, the measurement of the temperature of the thermally activatable adhesive being performed by determining a resistance of the flat heating element;
- wherein the resistance is determined by means of measuring synchronously a voltage and a current intensity, with a time difference between the measurement of the current intensity and the measurement of the voltage of ≤10 ms.
