Abstract

The invention relates to an arrangement for cooling electrical components (7, 13) on mechanical apparatuses which are driven by compressed air, for example automatic handling equipment. In order to make use of the compressed air in the mechanical elements (1, 2, 10) of the apparatus in a simple way for cooling the electrical components (7, 13) which are located on them, special outlet openings are provided on connections (3), which are generally like joints, or on ends of the elements (10), which outlet openings, together with deflection parts (6, 12) pass portions of the compressed air to the components (7, 13) which are to be cooled. The invention can primarily be used in automatic handling equipment, in industrial production. <IMAGE>

Description

Anordnung zur Kühlung von elektrischen Bauelementen anArrangement for cooling electrical components

druckluftbetriebenen mechanischen Geräten Die Erfindung betrifft eine Anordnung nach dem Oberbegriff des Anspruchs 1.Compressed Air Operated Mechanical Devices The invention relates to a Arrangement according to the preamble of claim 1.

Es ist üblich, beispielsweise bei druckluftbetriebenen Handhabungsautomaten (Robotern), die Druckluftkanäle im Innern der mechanischen Elemente, z. B. Handhabungsarme, vorzusehen. Zur Steuerung der Bewegungsvorgänge dieser mechanischen Geräte sind außen auf den mechanischen Elementen vorzugsweise elektrische Bauelemente angebracht (z. B. optische oder taktile Sensoren), mit denen die Umgebung dieser Geräte abtastbar ist. Viele dieser Sensorelemente sind besonders empfindlich gegen eine hohe Umgebungstemperatur, so daß hier eine Kühlung angezeigt ist.It is common, for example, in the case of automatic handling machines operated by compressed air (Robots), the compressed air ducts inside the mechanical elements, e.g. B. handling arms, to be provided. To control the movement processes of these mechanical devices are On the outside of the mechanical elements, preferably electrical components are attached (e.g. optical or tactile sensors) with which the surroundings of these devices can be scanned is. Many of these sensor elements are particularly sensitive to high ambient temperatures, so that cooling is indicated here.

Der Erfindung liegt die Aufgabe zugrunde, bei druckluftbetriebenen mechanischen Geräten eine aufwandsarme Kühlung von elektrischen Bauelementen an dem Gerät zu ermöglichen.The invention is based on the object in compressed air-operated mechanical devices a low-cost cooling of electrical components to enable the device.

Zur Lösung dieser Aufgabe sind bei einer Anordnung der eingangs angegebenen Art die im Kennzeichen des Anspruchs 1 angegebenen Merkmale vorhanden. Das Anbringen von Austrittsöffnungen im Bereich von Verbindungen oder Enden der mechanischen Elemente ist insofern vorteilhaft, als daß hier ohnehin besondere Dichtungsmaßnahmen notwendig sind, um einen Austritt der Druckluft weitgehend zu vermeiden oder im gewissen Umfang kalkulierbar zu machen. Da die Verbindungsstellen der mechanischen Elemente in der Regel eine Bewegung der mechanischen Elemente gegeneinander um mehrere Freiheitsgrade ermöglichen sollen, werden hier beispielsweise Labyrinthdichtungen zwischen den mechanischen Elementen angebracht. Diese Dichtungen können leicht mit einigen Austrittsöffnungen versehen werden, aus denen der vorgegebene Teil der Druckluft entweichen kann. Außerdem ist auch eine gewisse Abluft aus den Druckluftleitungen - vorzugsweise an den Enden - notwendig, um die Druckverhältnisse in den mechanischen Elementen zu regeln. Auch diese Abluft kann zur Kühlung von elektrischen Bauelementen herangezogen werden, indem auch sie durch Umlenkteile zu den elektrischen Bauelementen hingeführt wird.To solve this problem, in an arrangement, the above-mentioned Kind of the features specified in the characterizing part of claim 1 present. Attaching of outlet openings in the area of connections or ends of the mechanical elements is advantageous in that special sealing measures are necessary here anyway are to largely avoid or to a certain extent an escape of the compressed air to make it calculable. Since the joints of the mechanical elements in the Usually a movement of the mechanical elements against each other by several degrees of freedom should make possible here, for example, labyrinth seals attached between the mechanical elements. These seals can easily be used with some outlet openings are provided, from which the predetermined part of the compressed air can escape. There is also a certain amount of exhaust air from the compressed air lines - preferably at the ends - necessary to the pressure conditions in the mechanical Elements to regulate. This exhaust air can also be used to cool electrical components can be used by also passing them through deflection parts to the electrical components is led.

Vorteilhafte Ausführungsformen der erfindungsgemäßen Anordnung sind in den Unteransprüchen angegeben.Advantageous embodiments of the arrangement according to the invention are specified in the subclaims.

Die Erfindung wird anhand der Figuren erläutert, wobei Figur 1 eine erste Ausführungsform mit einer gelenkartigen Verbindung von mechanischen Elementen und Figur 2 eine zweite Ausführungsform an einem Ende eines mechanischen Elementes darstellen.The invention is explained with reference to the figures, wherein Figure 1 is a first embodiment with an articulated connection of mechanical elements and FIG. 2 shows a second embodiment at one end of a mechanical element represent.

In der Figur 1 sind mechanische Elemente 1 und 2 als Hand habungsarme eines mechanischen Gerätes, z. B. eines Handhabungsautomaten, mit einem Gelenk 3 dargestellt. Im Inneren der Elemente 1 und 2 ist ein Druckluftkanal 4 vorhanden, der am Gelenk 3 über eine Labyrinthdichtung 5 geführt ist. Die Labyrinthdichtung 5 ist mit Austrittsöffnungen versehen, die vorgegebene Teile der Druckluft im Druckluftkanal 4 aus dem Gelenk 3 herausführen. Am mechanischen Element 1 ist ein Umlenkteil 6 befestigt, welches das Gelenk 3 überdeckt und zum mechanischen Element 2 hin offen ist. Durch die offene Seite des Umlenkteils 6 kann somit der vorgegebene Teil der Druckluft des Druckluftkanals 4 austreten und beispielsweise ein elektrisches Bauelement 7 am mechanischen Element 2 kühlen. Das mechanische Element 2 kann hier z. B. die Hand des Handhabung automaten darstellen, die entsprechende taktile oder op- tische Sensoren als elektrische Bauelemente aufweist, um ein zu bearbeitendes oder zu transportierendes Werkstück zu detektieren.In the figure 1, mechanical elements 1 and 2 are dung as hand arms a mechanical device, e.g. B. a handling machine, with a joint 3 shown. Inside the elements 1 and 2 there is a compressed air duct 4, which is guided on the joint 3 via a labyrinth seal 5. The labyrinth seal 5 is provided with outlet openings, the predetermined parts of the compressed air in the compressed air channel 4 lead out of joint 3. A deflection part 6 is located on the mechanical element 1 attached, which covers the joint 3 and is open to the mechanical element 2 is. Through the open side of the deflecting part 6, the predetermined part of the Compressed air of the compressed air channel 4 emerge and, for example, an electrical component 7 on mechanical element 2 to cool. The mechanical element 2 can here, for. B. the Hand of the handling machine represent the corresponding tactile or op- tables Has sensors as electrical components in order to be processed or transported To detect workpiece.

In der Figur 2 ist ein mechanisches Element 10 gezeigt, das beispielsweise ebenfalls die Hand eines Handhabungsautomaten darstellen kann. Ein Druckluftkanal 11 im Inneren des mechanischen Elements 10 transportiert auch hier die Druckluft, wobei am Ende des Kanals 11 ein Rohr 12 als Umlenkteil angeordnet ist, das einen vorgegebenen Teil der Druckluft auf ein elektrisches Bauelement 13 führen kann. Auch hier ist somit gewährleistet, daß mit der aus dem Umlenkteil 12 austretenden Druckluft eine Kühlung des elektrischen Bauelements 13 erfolgen kann.In the figure 2, a mechanical element 10 is shown, for example can also represent the hand of a handling machine. A compressed air duct 11 inside the mechanical element 10 also transports the compressed air here, wherein at the end of the channel 11 a tube 12 is arranged as a deflecting part, the one predetermined part of the compressed air can lead to an electrical component 13. Here, too, it is ensured that with the emerging from the deflection part 12 Compressed air cooling of the electrical component 13 can take place.
