Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Evakuieren und Verschließen von Bildwiedergaberöhren nach dem Oberbegriff des Patentanspruches.The invention relates to a method and a device for evacuating and sealing picture tubes according to the preamble of the claim.
Die Evakuierung von Bildwiedergaberöhren erfolgt durch speziell für den jeweiligen Produktionsprozeß geeignete Pumpsysteme auf entsprechenden Pumpgestellen. Röhren mit Glasumhüllung werden in der Regel durch Glasrohre mit den Pumpsystemen verbunden. Diese Glasrohre, in der Fachspra che Pumpstengel genannt, werden nach dem Evakuieren durch Abschmelzen vom Pumpsystem getrennt. Der der Röhre zuge wandte Teil des Pumpstengels bleibt Bestandteil des Röh renfußes, auf den innere Bauteile der Röhre montiert sind. Für die Serienfertigung wird zum Abschmelzen eine Vorrichtung verwendet, welche als Abschmelzvorrichtung bezeichnet wird. Man unterscheidet 2 prinzipielle Ver fahren zur Ankopplung des Pumpstengels an das Pumpsy stem. Das Absenken der Bildwiedergaberöhre auf ein starr angeordnetes Pumpsystem oder das Hinführen des Pumpsy stems zum Pumpstengel. Der Pumpstengel taucht dabei durch die Abschmelzvorrichtung in das Pumpsystem ein und wird über eine vorgespannte oder durch eine über eine zusätz lich aufzubringende Kraft aktivierte Dichtung an das Pumpsystem angeschlossen.The display tubes are evacuated by especially suitable for the respective production process Pump systems on corresponding pump racks. Tubes with Glass envelopes are usually covered with glass tubes Pump systems connected. These glass tubes, in the specialist language called pump stalks, are evacuated by Melting separated from the pump system. The one drawn to the tube part of the pump stem remains part of the Röh renfußes, mounted on the inner components of the tube are. For series production, one is used for melting Device used as a melting device referred to as. There are two basic ver drive to connect the pump stem to the Pumpsy stem. Lowering the display tube to a rigid one arranged pump system or leading the Pumpsy stems to the pump stem. The pump stem dips through the melting device into the pump system and will via a pre-tensioned one or through an additional one force to be applied activated seal on the Pump system connected.
Die Abschmelzvorrichtung ist bei Verwendung von 65 mm langen Pumpstengeln auf dem Pumpgestell in einem Ab stand von 20 bis 30 mm vom Pumpsystem entfernt an Füh rungssäulen derart befestigt, daß eine Lageabweichung der Bildwiedergaberöhre durch manuelle Justage von Bildwie dergaberöhre und Abschmelzvorrichtung ausgeglichen werden kann. Die derzeitige Halterung der Abschmelzvorrichtung trägt diesem Erfordernis durch eine richtungsunabhängige Beweglichkeit in horizontaler Ebene Rechnung. Ziel der Erfindung ist es, ein Verfahren und eine Vorrichtung zum Evakuieren und Verschließen von Bildwiedergaberöhren zu entwickeln, welche es gestatten, den technologischen Teilschritt zur Verbindung des Pumpstengels der Bildwie dergaberöhre mit dem Pumpsystem zu automatisieren und durch Verwendung von Preßtellern mit einem 55 mm langen Pumpstengel die Pumpzeiten zu minimieren.The melting device is when using 65 mm long pump stems on the pump frame in one ab stood at 20 to 30 mm from the pumping system tion columns attached such that a positional deviation of the Image display tube by manual adjustment of image as the dispensing tube and melting device are balanced can. The current holder of the melting device contributes to this requirement by a directional Mobility in the horizontal plane. goal of Invention is a method and an apparatus for Evacuate and seal display tubes develop, which allow the technological Partial step to connect the pump stem of the picture as automate the transfer tube with the pump system and by using press plates with a 55 mm long Pump stem to minimize pumping times.
Die Aufgabe wird durch den kennzeichnenden Teil des Pa tentanspruches gelöst.The task is carried out by the defining part of Pa claim resolved.
Die Erfindung wird am Beispiel von Bildwiedergaberöhren erläutert.The invention is illustrated using the example of picture display tubes explained.
Die Abbildung zeigt die Abschmelzvorrichtung, bestehend aus den das Heizelement 4 umgebenden Isolier- und Pasi tionierelementen 5, 6, 7, 8, 9, 14, dem direkt an das Pumpsystem 1 angekoppelten Zentrierelement 10 und der ebenfalls mit diesen Bauelementen verbundenen trichter förmigen Anordnung 12 zur Vorzentrierung der Bildwie dergaberöhre. The figure shows the melting device, consisting of the insulating and pasi tioning elements 5 , 6 , 7 , 8 , 9 , 14 surrounding the heating element 4 , the centering element 10 directly coupled to the pump system 1 and the funnel-shaped arrangement 12 also connected to these components for pre-centering the picture tube.
Erfindungsgemäß wird die in der Halterung 11 abgelegte Bildwiedergaberöhre 2 in der über der HF-Spule 17 befind lichen trichterförmigen Anordnung 12 über den Röhrenhals 13 vorzentriert und bevor die Kontaktstifte 15 des Schei benfußes in die Abschmelzvorrichtung eintauchen im Zen trierelement 10 axial positioniert. Die dadurch noch vor handene Drehwinkelabweichung von max. 4° wird bei dem Eintauchen der Kontaktstifte 15 in die Kontaktfedern 16 durch eine zwangsweise Beweglichkeit der Abschmelzvor richtung um ihre eigene Achse ausgeglichen.According to the stored in the holder 11 display tube 2 in the above the RF coil 17 Lichen funnel-shaped arrangement 12 over the tube neck 13 and before the pins 15 of the Schei benfußes immerse in the melting device in Zen trier element 10 axially positioned. The still existing rotation angle deviation of max. 4 ° is compensated for by immersing the contact pins 15 in the contact springs 16 by a forced mobility of the melter on its own axis.
Durch das beschriebene Verfahren unter Nutzung der Vor richtung wird eine automatische Bestückung von Pump automaten für Bildwiedergaberöhren ermöglicht. Gleich zeitig werden hiermit die Voraussetzungen für den Einsatz kürzerer Pumpstengel geschaffen, die eine Optimierung des Pumpregimes gestatten. Die Handbarkeit der Abschmelz vorrichtung im Havariefall zur Reinigung und zur Beseiti gung von Glasresten wird durch einfaches Abheben der Vorrichtung nach oben verbessert.Through the procedure described using the pre direction is an automatic assembly of Pump Automatics for picture tubes enabled. Soon The requirements for use are hereby timely shorter pump stem created an optimization of the Allow pumping regimes. The manageability of the melting device in the event of an accident for cleaning and disposal Glass residue is removed by simply lifting the Device improved upwards.
