Le dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.
La fig. 1 est une vue schématique, en élévation, d'une installation de galvanoplastie, etThe drawing represents, by way of example, an embodiment of the subject of the invention. Fig. 1 is a schematic view, in elevation, of an electroplating installation, and
La fig. 2 est une vue en perspective, avec coupe partielle, d'une partie d'un détail de cette installation.Fig. 2 is a perspective view, partly in section, of part of a detail of this installation.
L'installation représentée est modulaire, seul un module étant entièrement visible au dessin.The installation shown is modular, only one module being entirely visible in the drawing.
Cette installation comprend un châssis 1 portant, sur sa partie supérieure la formant table, une série de cuves de traitement 2, en polypropylène, à rai¬ son d'une par module, et, logés dans sa partie inférieu-' re, sous la table la, une série de réservoirs 3, en poly¬ propylène également, contenant des bains de galvanoplastie, tel le bain représenté en 4 à la fig. 1 comme si le réser¬ voir était transparent. Les réservoirs 3 sont constitués par des enceintes fermées, ce qui protège les bains et les empêche de se dégrader.This installation comprises a frame 1 carrying, on its upper part forming the table, a series of treatment tanks 2, made of polypropylene, with one sound per module, and, housed in its lower part, under the table la, a series of tanks 3, also made of polypropylene, containing electroplating baths, such as the bath shown in 4 in FIG. 1 as if the container were transparent. The tanks 3 consist of closed enclosures, which protects the baths and prevents them from degrading.
Chaque réservoir 3 est relié à la cuve 2 située au-dessus de lui par un conduit 5 muni d'une pompe 6 destinée à puiser dans la cuve 2 le bain qu'il contient. Chaque cuve de traitement 2 est entourée par une cuve ex¬ térieure 7, de débordement ou de trop-plein, dont la hau¬ teur est supérieure à celle de la cuve de traitement, et dansEach tank 3 is connected to the tank 2 located above it by a conduit 5 provided with a pump 6 intended to draw from the tank 2 the bath which it contains. Each treatment tank 2 is surrounded by an external tank 7, of overflow or overflow, the height of which is greater than that of the treatment tank, and in

le fond de laquelle débouche un conduit de retour 8 destiné à ramener le bain 4 dans le réservoir 3. La contenance de chaque réservoir 3 étant supérieure à celle de la cuve 2 à laquelle il est associé, il est possible, au cours même du fonctionnement de l'installa¬ tion, de faire circuler le bain, sous l'effet de la pom¬ pe 6, entre le réservoir 3 et la cuve de traitement 2, le bain débordant de la cuve 2 et étant repris par la cuve de trop-plein 7 d'où il est ramené dans le réservoir 3. Cet agencement permet de donner aux bains un volume important grâce auquel les bains se dégradent moins, de sorte qu'ils n'ont pas à être changés aussi souvent que s'ils étaient entièrement contenus dans la cuve 2. Un conduit de vidange 9, de forte section, muni d'une vanne 10, permet, lorsque le traitement est terminé, de ramener rapidement dans le réservoir 3 tout le bain se trouvant dans la cuve 2. • WIPO the bottom of which opens a return duct 8 intended to bring the bath 4 back into the tank 3. The capacity of each tank 3 being greater than that of the tank 2 with which it is associated, it is possible, even during operation of the installation, to circulate the bath, under the effect of the pump 6, between the tank 3 and the treatment tank 2, the bath overflowing from the tank 2 and being taken up by the tank too -full 7 from where it is brought back into the reservoir 3. This arrangement makes it possible to give the baths a large volume thanks to which the baths degrade less, so that they do not have to be changed as often as if they were entirely contained in the tank 2. A large-diameter drain pipe 9, fitted with a valve 10, makes it possible, when the treatment is finished, to quickly return to the tank 3 all the bath present in the tank 2.
Il est à remarquer que chaque module de l'installation comprend en outre un filtre 11 muni d'une pompe 12 montée sur un conduit 13, ce qui permet de pré¬ lever du bain dans le réservoir 3, à l'aide de la pompe 12, de le filtrer et de le restituer au réservoir, ceci en continu. L'installation comprend en outre une sonde 14
à buts multiples servant en particulier à prélever des informations concernant la température du bain et son niveau dans le réservoir 3. Elle agit sur un corps de chauffe 15, immergé dans le bain, pour maintenir constante la température de celui-ci et agit également pour stopper le chauffage si, accidentellement, le niveau du bain vient à baisser au-delà d'une limite donnée.It should be noted that each module of the installation further comprises a filter 11 provided with a pump 12 mounted on a conduit 13, which makes it possible to pre-lift the bath in the tank 3, using the pump 12, to filter it and return it to the tank, this continuously. The installation also includes a probe 14 multipurpose serving in particular to take information concerning the temperature of the bath and its level in the tank 3. It acts on a heating body 15, immersed in the bath, to maintain constant the temperature thereof and also acts for stop the heating if, accidentally, the bath level drops beyond a given limit.
Chaque cuve de traitement 2, dont la matière est électriquement isolante, est munie, à son bord supé¬ rieur, d'un anneau métallique 16 relié, par une tige 17 et par un conducteur 18 schématique ent représenté, à la borne positive d'un redresseur de courant 19. Des tiges conductrices 20, formant anodes, sont suspendues à l'an¬ neau 16 et immergées dans le bain de traitement se trou¬ vant dans la cuve 2.Each treatment tank 2, the material of which is electrically insulating, is provided, on its upper edge, with a metal ring 16 connected, by a rod 17 and by a conductor 18 schematically shown, to the positive terminal of a current rectifier 19. Conductive rods 20, forming anodes, are suspended from the ring 16 and immersed in the treatment bath trou¬ vant in the tank 2.
Chaque module de 1'installation comprend en outre un vibreur électro-mécanique 21 situé sous la cuve de traitement 2, et reposant sur des traverses lb que pré¬ sente le châssis 1. Ce vibreur 21 est relié, par des biel- lettes 22, à un plateau 23 solidaire d'un arbre 24 traver¬ sant, de façon étanche, un trou central que présente la cuve 2. L'étanchéité est assurée par une membrane 25 agen¬ cée de façon telle que les mouvements rotatifs vibratoiresEach module of the installation further comprises an electro-mechanical vibrator 21 located under the treatment tank 2, and resting on crossbars lb which the chassis 1 presents. This vibrator 21 is connected, by connecting rods 22, to a plate 23 integral with a shaft 24 traver¬ sant, sealingly, a central hole that has the tank 2.

L'arbre 24 reçoit un panier 26, en polypropylène, représenté en détail à la fig. 2, dans lequel se placent les pièces à traiter. Le fond de ce panier, désigné par 27, également en poly¬ propylène, est hélicoïdal, la rampe ainsi formée se ter¬ minant après un tour par une paroi verticale 28 de quel¬ ques cm de hauteur, qui relie l'une à l'autre ses deux extrémités, supérieure et inférieure.-_ • WIPO IPO _> _ to which the shaft 24 is subjected under the effect of the vibrator 21 do not communicate with the tank 2. The shaft 24 receives a basket 26, made of polypropylene, shown in detail in FIG. 2, in which the parts to be treated are placed. The bottom of this basket, designated by 27, also made of polypropylene, is helical, the ramp thus formed ending after a revolution by a vertical wall 28 of a few cm in height, which connects one to the 'other its two ends, upper and lower.
Grâce à cet agencement, les pièces qui se 'trouvent sur le fond hélicoïdal 27 effectuent, sous l'ef¬ fetdes vibrations, un cheminement ascendant jusqu'au mo¬ ment où, parvenues au droit de la paroi verticale 28, el¬ les retombent en culbutant sur la partie inférieure de la rampe, pour reprendre leur cheminement sur celle-ci.With this arrangement, the parts that are 'located on the helical root 27 intervene, on the ef¬ fetdes vibrations, an upward path until mo¬ ment which, received by the right of the vertical wall 28, the fall el¬ by tumbling on the lower part of the ramp, to resume their progress on it.
Les perforations de la rampe hélicoïdale 27 sont munies de pastilles 29 percées d'un grand nombre de trous de faible dimension, à l'instar d'un tamis, ce qui permet une bonne circulation du bain de galvanoplastie à travers le panier 26, améliorant ainsi l'efficacité du bain et provoquant en outre un déplacement supplémentaire des pièces en traitement se trouvant dans le panier.
La rampe 27 porte, enrobées dans sa matière, trois barres métalliques radiales 30, disposées à 120° les unes des autres, en contact électrique avec l'arbre cen¬ tral 24. Ces barres 30 portent, vissées sur elles, des pastilles en acier inoxydable 31, noyées dans la matière de la rampe, dont la face supérieure affleure la face su¬ périeure de celle-ci. L'arbre 24 étant relié, par un con¬ ducteur 32 schématique ent représenté à la fig. 1, à la borne négative du redresseur 19, les pastilles 31, avec lesquelles des pièces en traitement sont toujours en con¬ tact, forment la cathode de l'installation. Ces pastilles, vissées sur les barres 30, sont facilement remplaçables lorsqu'elles sont revêtues du métal de déposition.The perforations of the helical ramp 27 are provided with pellets 29 pierced with a large number of small holes, like a sieve, which allows good circulation of the electroplating bath through the basket 26, improving thus the efficiency of the bath and causing further displacement of the parts being treated in the basket. The ramp 27 carries, coated in its material, three radial metal bars 30, arranged at 120 ° from each other, in electrical contact with the central shaft 24. These bars 30 carry, screwed onto them, steel pellets stainless 31, embedded in the material of the ramp, the upper face of which is flush with the upper face of the latter. The shaft 24 being connected, by a schematic conductor 32 shown in FIG. 1, at the negative terminal of the rectifier 19, the pellets 31, with which the parts being treated are always in contact, form the cathode of the installation. These pads, screwed onto the bars 30, are easily replaceable when they are coated with the deposition metal.
Chaque module comporte, outre le redresseur 19, une armoire de commande 32 dont les éléments qu'elle contient servent à régler la valeur du courant de traite¬ ment, le temps de travail du module, la fréquence et l'am¬ plitude des vibrations du vibreur 21, de même que la tem¬ pérature du bain, et permettent également la commande ma¬ nuelle du vibreur, des mouvements du bain comme aussi de toute autre fonction du module.
Each module comprises, in addition to the rectifier 19, a control cabinet 32 the elements of which it contains are used to adjust the value of the treatment current, the working time of the module, the frequency and the amplitude of the vibrations. of the vibrator 21, as well as the temperature of the bath, and also allow manual control of the vibrator, of the movements of the bath as also of any other function of the module.
