Description

Gebiet der ErfindungField of the invention

Die vorliegende Erfindung betrifft eine Vorrichtung zum Schneiden oder Perforieren von Polymer- und/oder Textilbauteilen im Fahrzeugbau.The present invention relates to a device for cutting or perforating polymer and / or textile components in vehicle construction.

Stand der TechnikState of the art

Das Einbringen von Sollbruchstellen in Airbag-Klappen ist allgemeiner Stand der Technik. Die Erzeugung dieser Sollbruchstellen erfolgt an Luft unter atmosphärischem Druck mittels Laserbearbeitung. Beim Laservorgang an Luft wird das abzutragende Material oftmals zu stark verbrannt (Sauerstoffgehalt fast 21%), was in einer optischen Sichtbarkeit der Sollbruchstelle auf der Airbag-Klappe resultiert. Diese unerwünschten, sichtbaren Fehlstellen müssen oftmals aufwendig nachbearbeitet werden.The introduction of predetermined breaking points in airbag flaps is generally state of the art. The generation of these predetermined breaking points takes place in air under atmospheric pressure by means of laser processing. During the laser process in air, the material to be removed is often too heavily burned (oxygen content almost 21%), resulting in an optical visibility of the predetermined breaking point on the airbag flap. These unwanted, visible defects must often be elaborately reworked.

Die DD 245 833 A1 beschreibt eine Vorrichtung für die Materialbearbeitung durch Laserstrahleinwirkung, wobei eine selektive Lasermaterialbearbeitung von Festkörperoberflächen und Schichten wahlweise im Vakuum oder unter definiert vorgegebener Gaseinwirkung in einem wählbaren Probentemperaturbereich mit hoher Positioniergenauigkeit des Laserstrahls realisiert wird.The DD 245 833 A1 describes a device for material processing by laser beam exposure, wherein a selective laser material processing of solid surfaces and layers is realized either in vacuum or under defined predetermined gas action in a selectable sample temperature range with high positioning accuracy of the laser beam.

Zusammenfassung der ErfindungSummary of the invention

Es ist Aufgabe der Erfindung eine verbesserte Airbag-Perforationsvorrichtung zum Schneiden oder Perforieren von Polymer- und/oder Textilbauteilen von Airbags im Fahrzeugbau vorzustellen, insbesondere eine Vorrichtung, die eine übermäßige ungewollte Verbrennung der Polymer- und Textilbauteile verhindert.The object of the invention is to present an improved airbag perforation device for cutting or perforating polymer and / or textile components of airbags in vehicle construction, in particular a device which prevents excessive unwanted combustion of the polymer and textile components.

Die Lösung der Aufgabe erfolgt durch eine Airbag-Perforationsvorrichtung zum Schneiden oder Perforieren von Polymer- und/oder Textilbauteilen von Airbags im Fahrzeugbau, umfassend einen Laser und eine Bearbeitungskammer, wobei der Laser zumindest teilweise in der Bearbeitungskammer angeordnet ist, wobei innerhalb der Bearbeitungskammer ein Unterdruck, Vakuum und/oder eine Schutzgasatmosphäre erzeugbar ist, wobei der Unterdruck und/oder das Vakuum über zumindest eine Vakuumpumpe erzeugbar ist, wobei die Polymer- und/oder Textilbauteile in die Bearbeitungskammer einbringbar sind, so dass sie durch den Laser bei Unterdruck, Vakuum oder in Schutzgasatmosphäre geschnitten oder perforiert werden können.The object is achieved by an airbag perforation device for cutting or perforating polymer and / or textile components of airbags in vehicle construction, comprising a laser and a processing chamber, wherein the laser is at least partially disposed in the processing chamber, wherein a negative pressure within the processing chamber , Vacuum and / or a protective gas atmosphere can be generated, wherein the negative pressure and / or the vacuum via at least one vacuum pump can be generated, wherein the polymer and / or textile components are introduced into the processing chamber, so that they by the laser at negative pressure, vacuum or can be cut or perforated in a protective gas atmosphere.

Die erfindungsgemäße Airbag-Perforationsvorrichtung umfasst einen Laser und eine Bearbeitungskammer, wobei der Laser zumindest teilweise in der Bearbeitungskammer angeordnet ist und der Erzeugung von Sollbruchstellen in Polymer- und/oder Textilbauteilen im Fahrzeugbau dient. Innerhalb der Bearbeitungskammer herrscht Unterdruck, Vakuum oder eine Schutzgasatmosphäre, in diesem Fall bevorzugt eine Stickstoff- oder Argon-Atmosphäre. Das Vakuum und/oder der Unterdruck innerhalb der Bearbeitungskammer werden über zumindest eine geeignete Vakuumpumpe bevorzugt innerhalb eines Zeitraums von wenigen Sekunden erzeugt.The airbag perforation device according to the invention comprises a laser and a processing chamber, wherein the laser is at least partially disposed in the processing chamber and serves to generate predetermined breaking points in polymer and / or textile components in vehicle construction. Within the processing chamber, there is negative pressure, vacuum or a protective gas atmosphere, in this case preferably a nitrogen or argon atmosphere. The vacuum and / or the negative pressure within the processing chamber are preferably generated by means of at least one suitable vacuum pump within a period of a few seconds.

Die optionale Zufuhr von Schutzgas und Bearbeitung der Polymer- und/oder Textilbauteile in Schutzgasatmosphäre, insbesondere Stickstoff- oder Argon-Atmosphäre, in die Bearbeitungskammer erfolgt aus konventionellen Gasflaschen über geeignete Ventile, die an der Bearbeitungskammer vorgesehen sind.The optional supply of protective gas and processing of the polymer and / or textile components in a protective gas atmosphere, in particular nitrogen or argon atmosphere, into the processing chamber is carried out from conventional gas cylinders via suitable valves which are provided on the processing chamber.
