Abstract

A device for the supply of protective gas to a heated workpiece has a temperature measuring device, for measuring the workpiece temperature, and a protective gas supply which is directed onto the heated workpiece. Here, the temperature measuring device is arranged within the end section of this protective gas supply, as a result of which a considerable saving in space is effected and also very precise temperature measurement, since the exit opening of the protective gas can also be used as a diaphragm for an IR sensor of the temperature measuring device, the temperature measurement being carried out in addition under the influence of protective gas.

Description

Die Erfindung betrifft eine Vorrichtung zur Zufuhr von Schutzgas an ein beheiztes Werkstück.The invention relates to a device for supplying protective gas a heated workpiece.

Die Schutzgaszufuhr an ein Werkstück ist beispielsweise bei der automatischen Durchführung von Lötungen an einem Werkstück üblich. Insbesondere bei kleineren Werkstücken taucht hierbei das Problem auf, daß im unmittelbaren Bereich der Lötstelle mehrere Einrichtungen angeordnet sind oder dort enden, nämlich Heizeinrichtungen wie z. B. HF-Heizungen für das Werkstück, eine Vorrichtung zur Temperatur­ messung des Werkstückes zur ordnungsgemäßen Steuerung des Lotdraht­ vorschubes, Vorschubeinrichtungen oder Führungseinrichtungen für den Lotdraht und ein Zufuhrrohr oder ähnliches zur Versorgung der Lötstelle mit dem Schutzgas. Es wird daher im Bereich der Lötstelle unter Umständen sehr schwierig, diese Vorrichtungen so anzuordnen, daß sie einerseits optimal ihren jeweiligen Zweck erfüllen, andererseits sich aber nicht gegenseitig behindern.The shielding gas supply to a workpiece is, for example, at automatic execution of soldering on a workpiece common. The problem arises in particular with smaller workpieces on that in the immediate area of the solder joint several facilities are arranged or end there, namely heating devices such. B. HF heaters for the workpiece, a device for temperature Measurement of the workpiece for proper control of the solder wire feeders, feed devices or guide devices for the Solder wire and a feed tube or the like to supply the Soldering point with the protective gas. It is therefore in the area of the solder joint may be very difficult to arrange these devices that on the one hand they optimally fulfill their respective purpose, on the other hand, do not interfere with each other.

Es ist daher Aufgabe der Erfindung, durch konstruktive Maßnahmen hier eine Erleichterung zu schaffen.It is therefore an object of the invention by constructive measures here to create a relief.

Erfindungsgemäß wird diese Aufgabe durch den kennzeichnenden Teil des Patentanspruchs 1 gelöst. According to the invention, this object is achieved by the characterizing part of the Claim 1 solved.  

Der wesentliche Erfindungsgedanke besteht also in der integrierten Ausführung einer Schutzgasvorrichtung und einer Temperaturmeßein­ richtung.The main idea of the invention is the integrated one Execution of a protective gas device and a temperature measurement direction.

Diese Anordnung hat den Vorteil der Raumersparnis, ermöglicht eine präzise Temperaturmessung, da die Austrittsöffnung des Schutzgases auch als Blende für einen IR-Sensor der Temperaturmeßeinrichtung dienen kann, außerdem erfolgt die Temperaturmessung unter Schutz­ gaseinfluß und damit können auch Verunreinigungen des IR-Sensors vermieden werden.This arrangement has the advantage of saving space, enables a precise temperature measurement because of the outlet opening of the protective gas also as an aperture for an IR sensor of the temperature measuring device can also serve, the temperature measurement takes place under protection Influence of gas and thus also contamination of the IR sensor be avoided.

Ausgestaltungen dieser Lösung sind den Unteransprüchen zu entnehmen; ein Ausführungsbeispiel wird anhand der Zeichnung näher erläutert:Refinements of this solution can be found in the subclaims; an embodiment is explained in more detail with reference to the drawing:

Die Figur zeigt einen Querschnitt durch die im Bereich eines Werk­ stückes 20 angeordneten Einrichtungen, nämlich ein im wesentlichen zylindrisches Bauteil 12 als Endabschnitt einer Schutzgaszuführung, das sich zur Austrittsöffnung hin konisch verjüngt, eine HF- Heizeinrichtung 21 gegenüber der Austrittsöffnung der Schutzgaszu­ führung und eine Führungseinrichtung 31 zur Führung des Lotdrahtes 30 (dessen Vorschubeinrichtungen sind nicht dargestellt) an das Werkstück 20.The figure shows a cross section through the devices arranged in the area of a workpiece 20 , namely an essentially cylindrical component 12 as the end section of a protective gas supply, which tapers conically towards the outlet opening, an HF heating device 21 with respect to the outlet opening of the protective gas supply and a guide device 31 for guiding the solder wire 30 (its feed devices are not shown) to the workpiece 20 .

Das Bauteil 12 ist gegenüber der Austrittsöffnung mit einer Stirn­ seite 12A abgeschlossen, in die eine Temperaturmeßeinrichtung 10 mit frontal angeordnetem IR-Sensor koaxial zur Längsachse A-A des Bauteils 12 eingelassen ist, so daß der Sensor 11 die aktuelle Temperatur des Werkstückes 20 erfassen kann.The component 12 is opposite the outlet opening with a front side 12 A, in which a temperature measuring device 10 with a front-mounted IR sensor is inserted coaxially to the longitudinal axis AA of the component 12 , so that the sensor 11 can detect the current temperature of the workpiece 20 .

Die Zuführung des Schutzgases S erfolgt über eine seitliche Einlaß­ öffnung 12B, die in Strömungsrichtung oberhalb des Sensors 11A der Temperaturmeßeinrichtung 10 liegt, so daß gewährleistet ist, daß der IR-Sensor in der Strömung des Schutzgases liegt.The protective gas S is supplied via a lateral inlet opening 12 B, which lies in the flow direction above the sensor 11 A of the temperature measuring device 10 , so that it is ensured that the IR sensor is in the flow of the protective gas.
