Description

Die Erfindung betrifft eine Sicherheitsblende für handgeführte Laser-Beschriftungsgeräte oder Laser-Materialbearbeitungsvorrichtungen. Der Erfindung liegt das Problem zugrunde, die Laserdichtheit bei der Benutzung handgeführter Geräte auf einfach handhabbare Weise zu gewährleisten, um insbesondere bei der Beschriftung bzw. Bearbeitung von Werkstücken, deren zur Beschriftung bzw. Bearbeitung vorgesehene Fläche kleiner ist als das Scanfeld des Lasergerätes, wie dies beispielsweise bei der Laser-Beschriftung von Wälzlagerringen der Fall ist, einen Strahlungsaustritt neben der Fläche zu verhindern.The The invention relates to a safety panel for hand-held laser marking devices or Laser material processing devices. The invention is the Problem based, the laser-tightness when using hand-held devices on easy to handle Way to ensure especially in the labeling or processing of workpieces whose surface intended for labeling or processing is smaller than the scan field of Laser device, as for example in the laser marking of rolling bearing rings the case is to prevent radiation leakage adjacent to the surface.

Die Erfindung löst diese Aufgabe gemäß Schutzanspruch 1 mit einer aus einer Rahmenplatte mit wenigstens einer einen umlaufenden Aufsetzrand für den Strahltrichter des Lasergerätes aufweisenden Blendenöffnung und wenigstens einer den Strahldurchtrittsbereich der Blendenöffnung verändernden Blendenlamelle bestehenden Sicherheitsblende, wobei die Blendenlamelle mit einem Betätigungs- oder Feststellmittel verbunden ist. Vorteilhaft weitergebildet ist die Erfindung, indem die Rahmenplatte über Anschlagmittel für eine sichere Positionierung am Werkstück verfügt, wobei insbesondere die Anschlagmittel verstellbar ausgebildet sind. Die Rahmenplatte kann vorteilhaft über wenigstens einen Handgriff zur Verbesserung der Handhabung und/oder über Befestigungsmittel zur lösbaren oder festen Verbindung zwischen Rahmenplatte, Lasergerät und/oder Werkstück verfügen.The Invention solves this task according to protection claim 1 with one of a frame plate with at least one a circumferential Aufsetzrand for the radiation cone of the laser device having aperture and at least one diaphragm blade changing the beam passage area of the diaphragm opening existing safety screen, with the shutter blade with a actuating or locking means is connected. Advantageously developed the invention by the frame plate via stop means for a secure Positioning on the workpiece features, in particular, the stop means are designed to be adjustable. The frame plate can advantageously via at least one handle for improving the handling and / or fastening means for releasable or firm connection between frame plate, laser device and / or workpiece feature.

Die erfindungsgemäße Rahmenplatte wird auf dem Werkstück positioniert, so dass sich die Blendenöffnung über der zu beschriftenden bzw. zu bearbeitenden Fläche befindet. Vorteilhaft liegen dabei die Anschlagmittel geeignet am Werkstück an oder werden nach dem Auflegen der Rahmenplatte entsprechend eingestellt bzw. gespannt. Die zu beschriftende bzw. zu bearbeitende Fläche des Werkstücks kann in wenigstens einer Koordinate kleiner sein als die Blendenöffnung. Damit dennoch keine Strahlung am Werkstück vorbei austreten kann, wird mittels der Blendenlamelle die Blendenöffnung den zu beschriftenden bzw. zu bearbeitenden Flächenbereich des Werkstücks frei lassend verschlossen. Die Anzahl und Form der Blendenlamellen richtet sich nach den zu beschriftenden bzw. zu bearbeitenden Werkstücken und/oder den zu schreibenden Informationen bzw. dem auszuführenden Bearbeitungsgang. Die Blendenlamelle wird mittels des Feststellmittels fixiert. Genauso ist es möglich, eine zunächst geschlossene Lamelle nur für die Zeitdauer des Beschriftungs- bzw. Bearbeitungsvorgangs mittels geeigneter Betätigungsmittel zu öffnen.The Frame plate according to the invention gets on the workpiece positioned so that the aperture above the label or to be machined surface located. Advantageously, the stop means are suitable for workpiece on or are adjusted accordingly after placing the frame plate or curious. The area to be labeled or processed workpiece may be smaller than the aperture in at least one coordinate. So that no radiation can escape the workpiece over, is by means of the shutter blade the aperture the area of the workpiece to be marked or machined freely leaving closed. The number and shape of the aperture blades directs depending on the workpieces to be inscribed or machined and / or the information to be written or the one to be executed Machining operation. The diaphragm blade is fixed by means of the locking means. It is equally possible one at first closed louvre only for the duration of the labeling or editing process by means of suitable actuating means to open.

Nachfolgend wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der Zeichnung näher erläutert. Die Zeichnung zeigt
eine perspektivische Ansicht einer erfindungsgemäßen Sicherheitsblende.Hereinafter, a preferred embodiment of the invention will be explained in more detail with reference to the drawing. The drawing shows
a perspective view of a security panel according to the invention.

Eine metallene, rechteckige Rahmenplatte 1 ist mit einer quadratischen Blendenöffnung 2 versehen, deren Randbereich 21 umlaufend eine Fixierkante zum Aufsetzen des Lasergerätes bildet und gegebenenfalls eine elastische Beschichtung zur Verbesserung der Dichtigkeit aufweist. Außerhalb der Blendenöffnung 2 sind zwei Handgriffe 4 mit der Rahmenplatte 1 verbunden. Zur Befestigung der Rahmenplatte 1 auf dem Werkstück W dienen Anschlagmittel 5, die als in Längsrichtung der Rahmenplatte 1 verschiebbare Stäbe ausgebildet sind und mittels Feststellschrauben 51 arretiert werden. Die Blendenöffnung 2 ist in der Abbildung durch sechs in Längsrichtung der Rahmenplatte 1 verschiebbare Lamellen 3 vollständig verschlossen. Die Lamellen 3 sind in drei Bahnen jeweils stirnseitig aneinander stoßend angeordnet. Im dargestellten geschlossenen Zustand entsteht dadurch die Stoßlinie B. Durch entsprechendes Verschieben der Lamellen 3 und Feststellen mittels der Feststellschrauben 31 wird das Beschriftungs- bzw. Bearbeitungsfeld freigegeben. Das Ausführungsbeispiel einer erfindungsgemäßen Sicherheitsblende dient der Beschriftung von Wälzlagerringen W und zeigt deshalb eine bogenförmige Stoßlinie B, so dass durch Verschieben wenigstens einer Lamelle 3 eine Öffnung in Form eines Ringsegmentes entsteht, wodurch nur ein Ausschnitt der Wälzlagerringflanke mit Laserstrahlung beaufschlagt wird und keine Strahlung am Werkstück W vorbei in den Raum gelangen kann.A metal, rectangular frame plate 1 is with a square aperture 2 provided, whose edge area 21 circumferentially forms a fixing edge for placing the laser device and optionally has an elastic coating to improve the tightness. Outside the aperture 2 are two handles 4 with the frame plate 1 connected. For fastening the frame plate 1 on the workpiece W serve stop means 5 that is considered longitudinally of the frame plate 1 sliding rods are formed and by means of locking screws 51 be arrested. The aperture 2 is in the figure by six in the longitudinal direction of the frame plate 1 movable slats 3 completely closed. The slats 3 are arranged in three tracks each abutting each other frontally. In the illustrated closed state thereby creates the joint line B. By appropriate displacement of the slats 3 and fixing by means of the locking screws 31 the caption or edit field is released. The embodiment of a safety panel according to the invention is used to inscribe rolling bearing rings W and therefore shows an arcuate joint line B, so that by moving at least one blade 3 an opening in the form of a ring segment is formed, whereby only a portion of the Wälzlagerringflanke is acted upon by laser radiation and no radiation on the workpiece W can pass into the room.

Zur Verbindung der Rahmenplatte 1 mit dem Werkstück W können außer den verstellbaren Anschlagmitteln 5 magnetische, durch Unterdruck wirkende oder federnd rastende Befestigungsmittel eingesetzt werden. Auch kann eine erfindungsgemäße Sicherheitsblende geeignet modifiziert ausgebildet in der gleichen Weise mit einem Lasergerät fest oder lösbar verbunden sein.To connect the frame plate 1 with the workpiece W can except the adjustable slings 5 magnetic, acting by negative pressure or resiliently latching fasteners are used. Also, a security panel according to the invention may be formed suitably modified in the same way with a laser device permanently or detachably connected.
