Abstract

Claims (25)

1 . A method for an automated mounting of insulating elements on structural elements of motor vehicles, the method comprising the steps of:

providing a plurality of insulating elements, wherein an insulating element in each case comprises a carrier, an expandable material which is arranged on the carrier, and at least one fixing element for fixing the insulating element on the structural element;

gripping individual insulating elements by a robot, wherein the robot is designed as a multi-axis robot with a gripper; and

mounting in each case an insulating element on a structural element by the robot, wherein the at least one fixing element of the insulating element is inserted into an opening in the structural element.

2 . The method as claimed in claim 1 , wherein the insulating elements are provided in a stack when they are provided, all the insulating elements stacked on top of one another being oriented substantially identically in space.

3 . The method as claimed in claim 1 , wherein the robot moves the insulating element in at least two different application directions when inserting the fixing element into the opening.

4 . The method as claimed in claim 1 , wherein the method comprises the further step of:

testing that the insulating element is correctly mounted on the structural element, in that the robot loads the insulating element in at least one testing direction which is inclined by at least 45° from an application direction, and/or in that the robot loads the insulating element in at least one testing direction which substantially corresponds to a direction of rotation of the insulating element.

5 . The method as claimed in claim 4 , wherein the robot loads the insulating element in at least two different testing directions during testing.

6 . The method as claimed in claim 4 , wherein during testing a force of at least 5 N and/or at most 200 N is applied by the robot to the mounted insulating element.

7 . The method as claimed in claim 4 , wherein the method comprises the further step of:

sorting out the insulating element if the insulating element is detached from the structural element during testing.

8 . The method as claimed in claim 7 , wherein the method comprises the further step of:

interrupting the automated operation if three or more insulating elements out of ten insulating elements mounted one after the other are each detached from the structural element during testing.

9 . The method as claimed in claim 1 , wherein the robot applies a force of at least 70 N to the fixing element during mounting.

10 . An insulating element for sealing off a structural element in a motor vehicle, the insulating element comprising:

a carrier;

an expandable material which is arranged on the carrier; and

at least one fixing element for fixing the insulating element on the structural element;

wherein the insulating element is designed for automated mounting as claimed in claim 1 .

11 . The insulating element as claimed in claim 10 , wherein the fixing element has a guide element which is designed as an extension at one end of the fixing element in an intended application direction.

12 . The insulating element as claimed in claim 11 , wherein the guide element has a height in the application direction of between 0.5 and 5 mm.

13 . The insulating element as claimed in claim 10 , wherein the insulating element comprises at least two fixing elements, and wherein at least one of these fixing elements is designed as a fastening clip with a snap closure.

14 . The insulating element as claimed in claim 10 , wherein a height of the fixing element in the application direction, which increases over the structural element in a mounted state, is at most 5 mm.

15 . The insulating element as claimed in claim 10 , wherein the fixing element is of asymmetrical design, with a first half of the fixing element being designed to be higher by a height in the application direction than a second half of the fixing element.
