W I () Dispositif de préhension robotisé pour la manipulation de pièces deW I () Robotic gripping device for handling workpieces
carrosserie dans une installation d'assemblage de véhicules La présente invention concerne un dispositif de préhension robotisé pour la manipulation de pièces de carrosserie dans une installation d'assemblage de véhicules, du type comprenant un support solidaire d'un robot et des moyens mécaniques de serrage et/ou de centrage commandés par au moins un vérin pneumatique, lesdits moyens pouvant occuper une position stable de serrage et/ou de centrage et une position stable de libération de la ou des pièces à assembler. La robotisation des chaînes d'assemblage de carrosserie de véhicules automobiles est devenue prépondérante du fait des The present invention relates to a robotic gripping device for handling body parts in a vehicle assembly installation, of the type comprising a support secured to a robot and mechanical clamping means and / or centering controlled by at least one pneumatic cylinder, said means being able to occupy a stable position for tightening and / or centering and a stable position for releasing the part or parts to be assembled. Robotization of motor vehicle body assembly lines has become dominant due to the
avantages technologiques et économiques qu'elle présente. technological and economic advantages it presents.
Cette robotisation est essentiellement utilisée pour le soudage ou la manutention avec ou sans géométrie des pièces This robotization is mainly used for welding or handling with or without geometry of the parts

La pince de soudage peut être montée sur un robot qui l'amène périodiquement, selon un programme informatisé, à un emplacement de soudage o elle effectue le soudage programmé de pièces préalablement amenées à cet emplacement, puis le robot ramène la pince de soudage à une position de repos. Une autre technologie consiste à disposer les pinces de soudage à des emplacements fixes auxquels un robot amène périodiquement les pièces à souder, ces pièces étant The welding clamp can be mounted on a robot which periodically brings it, according to a computerized program, to a welding location where it carries out the programmed welding of parts previously brought to this location, then the robot brings the welding clamp to a rest position. Another technology consists in placing the welding tongs at fixed locations to which a robot periodically brings the parts to be welded, these parts being
1) maintenues par un dispositif de préhension. 1) held by a gripping device.
C'est à cette dernière technologie que se réfère la présente invention. Dans tous les cas, la multiplication des sources d'énergie, énergie électrique pour la commande des robots et énergie pneumatique ou hydraulique pour la commande des organes solidaires du robot, pince de soudage dans le premier cas ou dispositif de préhension dans le second cas, présente des inconvénients aussi bien pour la conception que pour It is to this latter technology that the present invention refers. In all cases, the multiplication of energy sources, electrical energy for controlling the robots and pneumatic or hydraulic energy for controlling the components integral with the robot, welding tongs in the first case or gripping device in the second case, has drawbacks both for design and for
l'exploitation des chaines d'assemblage. the operation of assembly lines.
Une solution évidente consiste à utiliser l'énergie électrique, indispensable pour la commande des robots, An obvious solution is to use electrical energy, essential for controlling robots,
également pour la commande des organes portés par le robot. also for controlling the components carried by the robot.
C'est ainsi qu'on a vu apparaître des pinces de soudage à commande électrique, dont la mise au point a été longue et délicate. Cette solution, dans le cas de dispositifs de préhension robotisés, présente cependant divers inconvénients liés en particulier au mode de fonctionnement à deux positions This is how we saw the appearance of electrically controlled welding tongs, the development of which was long and delicate. This solution, in the case of robotic gripping devices, however has various drawbacks linked in particular to the two-position operating mode
stables des moyens mécaniques de serrage et/ou de centrage. stable mechanical tightening and / or centering means.
En outre, le montage de moteurs électriques embarqués et leur alimentation par l'intermédiaire de variateurs et systèmes d'asservissement posent des problèmes de poids et d'encombrement et remettent en question toute la structure In addition, the mounting of on-board electric motors and their power supply via variators and servo systems pose problems of weight and space and challenge the entire structure.

surcoût par rapport aux commandes à fluide traditionnellement utilisées. additional cost compared to the fluid controls traditionally used.
La présente invention vise à résoudre ces problèmes de The present invention aims to solve these problems of
manière simple, économique et efficace, en permettant en outre l'équipement de dispositifs de préhension existants. simple, economical and efficient way, while also allowing the equipment of existing gripping devices.
A cet effet, le dispositif de préhension selon l'invention 1W est caractérisé par le fait que ledit vérin pneumatique est alimenté par un compresseur électrique embarqué alimenté en courant électrique à partir d'une source fixe et commandé de To this end, the gripping device according to the invention 1W is characterized in that said pneumatic cylinder is supplied by an on-board electric compressor supplied with electric current from a fixed source and controlled from
manière programmée.programmed way.
L'utilisation d'un compresseur électrique embarqué permet de supprimer toute source externe d'alimentation en fluide alors même que la commande des moyens mécaniques de serrage et/ou centrage est faite, de manière éprouvée et traditionnelle, The use of an on-board electric compressor makes it possible to eliminate any external source of fluid supply even though the control of the mechanical tightening and / or centering means is done, in a proven and traditional manner,
par au moins un vérin pneumatique.by at least one pneumatic cylinder.
2) Le poids et le prix du compresseur embarqué peuvent être relativement bas, du fait que les pressions nécessaires au déplacement des moyens mécaniques dans leurs deux positions 2) The weight and the price of the on-board compressor can be relatively low, because the pressures necessary to move the mechanical means in their two positions
sont relativement faibles, de l'ordre de quelques bars. are relatively small, on the order of a few bars.
En outre, le vérin pneumatique n'étant actif que lors du passage de la position de serrage à la position de desserrage et inversement, on peut prévoir que l'alimentation électrique du compresseur est commandée pour être interrompue dans les In addition, the pneumatic cylinder being active only when passing from the clamping position to the loosening position and vice versa, it can be provided that the electrical supply to the compressor is controlled to be interrupted in the
3 positions de serrage, de desserrage ou de pression. 3 tightening, loosening or pressure positions.
L'invention facilite en outre la commande de l'ensemble du dispositif de préhension, à partir d'une source d'alimentation électrique unique et par une baie The invention further facilitates the control of the entire gripping device, from a single electrical power source and through a rack.
