Abstract

A robot tool for placing sealing plugs in openings in a vehicle body component includes a placing installation, in which a plug magazine having a plurality of plugs is accommodated, which plugs can be set into the respective openings in direct succession by the placing installation without reloading. A method is provided for securely setting the plugs, wherein the plugs can be pushed out of the plug magazine accommodated in the placing installation in predefined steps by a drive unit, wherein the plug magazine extends axially in an axial direction and the drive unit is arranged on the plug magazine at an angle of 90-170° to the axial direction.

First claim

What is claimed is:

1. A robot tool for placing sealing plugs into openings in an automotive body component, comprising:
a sealing plug magazine having a plurality of lined-up sealing plugs;
a placing installation on which the sealing plug magazine is disposed, wherein via the placing installation the plurality of the sealing plugs are capable of being placed in a directly sequential manner and without reloading into respective openings of the automotive body component;
a drive unit configured to eject the sealing plugs in predefined steps from the sealing plug magazine disposed on the placing installation, wherein
the sealing plug magazine extends in an axial direction, and
the drive unit is disposed relative to the sealing plug magazine at an angle of 90° to 170° in relation to the axial direction.

2. The robot tool according to claim 1 , further comprising:
an encircling elastic lip provided on an outlet of the placing installation that holds the sealing plugs in the sealing plug magazine, wherein
via an axial movement of the sealing plugs, the elastic lip is capable of being elastically bent in the axial direction of the robot tool.

3. The robot tool according to claim 2 , wherein
each of the sealing plugs has a non-elastic cover, and
a forward most sealing plug in the region of the placing installation is held on the cover by the elastic lip.

4. The robot tool according to claim 1 , wherein
the robot tool is adapted for human-robot interaction, and
the placing installation is capable of being guided to the openings sequentially and in an automated manner.

5. The robot tool according to claim 1 , wherein
the robot tool is configured to receive interchangeable placing installations, wherein dissimilar sealing plugs are placeable via different placing installations into respectively dissimilar openings.

6. A robot tool for placing sealing plugs into openings in an automotive body component, comprising:
a sealing plug magazine having a plurality of lined-up sealing plugs;
a placing installation on which the sealing plug magazine is disposed, wherein via the placing installation the plurality of the sealing plugs are capable of being placed in a directly sequential manner and without reloading into respective openings of the automotive body component;
a drive unit configured to eject the sealing plugs in predefined steps from the sealing plug magazine disposed on the placing installation, wherein
the sealing plug magazine extends in an axial direction,
the drive unit is disposed relative to the sealing plug magazine at an angle of 90° to 170° in relation to the axial direction,
the drive unit comprises a motor and a flexible brush cable configured as an indexing element, and
the brush cable is connected to a slide that is capable of being repositioned in the axial direction and by way of which the sealing plugs are capable of being moved out of the sealing plug magazine.

7. The robot tool according to claim 6 , wherein the brush cable has a deflection at an angle of 60° to 120°.

8. The robot tool according to claim 7 , wherein
the drive unit further comprises a drive that engages the brush cable and during operation moves the brush cable such that the brush cable repositions the slide.

9. The robot tool according to claim 6 , wherein
the drive unit further comprises a drive that engages the brush cable and during operation moves the brush cable such that the brush cable repositions the slide.

10. A method for placing a sealing plug into an opening in an automotive body component via a robot tool according to claim 1 , the method comprising the steps of:
ejecting the sealing plug to be placed from an outlet of the placing installation by a predetermined amount via the drive unit;
inserting the partially ejected sealing plug via the placing installation in an automated manner into the opening to be closed such that a portion of the sealing plug engages in the opening from behind so as to be held therein;
ejecting the sealing plug from the placing installation;
retracting the placing installation, wherein
the sealing plug, via the drive unit, is ejected in predefined steps from the sealing plug magazine disposed in a placing installation, and
the sealing plug magazine extends axially in an axial direction and the drive unit is disposed on the sealing plug magazine at an angle of 90° to 150° in relation to the axial direction.

11. The method according to claim 10 , wherein
in order for the sealing plug to be placed, the placing installation is configured to freely oscillate, wherein the sealing plug, via an oscillating movement of the placing installation, is positioned in a self-acting manner with respect to the opening to be closed.
