Abstract

Device for chemical treatment of articles of small size. It consists of a tank 1 with double-walled lid 2 pierced with orifices 8. In the bottom of the tank, intended to receive a chemical bath B, there is an air diffuser 5 providing mixing. The articles to be treated are supported by removable slides 12 housed in sleeves 11 attached to the tank. This device is intended for amateurs to permit development, the etching of printed circuits or the production of artistic etchings.

Description

La présente invention concerne un dispositif de traitement chimique d'articles et, plus particulièrement, elle vise une cuve pouvant servir au développement (révélation de résine photosensible), à la gravure (attaque par perchlorure de fer) des circuits imprimés électroniques ou à d'autres applications telles que la réalisation de gravures sur cuivre ou autres matériaux. Plus précisément, l'invention concerne une cuve destinée aux amateurs qui ont à travailler des articles de dimensions réduites, le dispositif de l'invention étant conçu pour une utilisation aisée dans des conditions de sécurité maximale et pour un coût aussi réduit que possible.The present invention relates to a device for the chemical treatment of articles and, more particularly, it relates to a tank which can be used for the development (development of photosensitive resin), for etching (attack by iron perchloride) of electronic printed circuits or for other applications such as making engravings on copper or other materials. More specifically, the invention relates to a tank intended for amateurs who have to work with articles of reduced dimensions, the device of the invention being designed for easy use under conditions of maximum safety and at a cost as low as possible.

Dans cette optique, le dispositif de-l'invention se caractérise par le fait qu'il est constitué d'un bac destiné à recevoir un bain chimique et contenant au moins un diffuseur d'air fixé à la partie basse de l'espace intérieur du bac, le ou les dits diffuseurs étant reliés à une pompe à air extérieure alimentant le ou les diffuseurs pour assurer un brassage du bain chimique, le bac étant obstrué par un couvercle à double paroi perce d'orifices décalés permettant l'évacuation de l'air de brassage injecté dans le bain tout en interdisant les projections, au moins un moyen de retenue des articles à traiter étant en outre prévu à l'intérieur du bac.With this in mind, the device of the invention is characterized by the fact that it consists of a tank intended to receive a chemical bath and containing at least one air diffuser fixed to the lower part of the interior space. of the tank, the said diffuser (s) being connected to an external air pump supplying the diffuser (s) to ensure mixing of the chemical bath, the tank being obstructed by a double-walled cover pierced with offset orifices allowing the evacuation of the mixing air injected into the bath while preventing splashes, at least one means for retaining the articles to be treated is also provided inside the tank.

Le moyen de retenue des articles est constitué par une glissière verticale logée à l'intérieur de la paroi latérale du bac et s'étendant sur toute la hauteur de celui-ci.The means for retaining the articles is constituted by a vertical slide housed inside the side wall of the container and extending over the entire height thereof.

Les produits de traitement peuvent être soit utilisés à la température ambiante, soit être réchauffés par l'introduction dans la cuve d'une résistance chauffante étanche du type de celles utilisées dans les aquariums.The treatment products can either be used at room temperature or be warmed up by the introduction into the tank of a waterproof heating resistor of the type used in aquariums.

On décrira à présent l'invention, à titre d'exemple non limitatif, en référence au dessin annexé dans lequel: la figure 1 est une vue d'ensemble d'une cuve selon l'inventian; la figure 2 est une coupe selon le repère r -= de la figure 1 et la figure 3 représente une glissière de retenue d'un article à traiter coulissant dans un manchon normalement solidaire du bac. The invention will now be described, by way of nonlimiting example, with reference to the appended drawing in which: FIG. 1 is an overall view of a tank according to the inventian; Figure 2 is a section along the reference r - = of Figure 1 and Figure 3 shows a slide for retaining an article to be treated sliding in a sleeve normally attached to the tray.

L'ensemble se compose d'un bac en plastique choc transparent 1 fermé par un double couvercle 2 et pouvant être fixé (notamment par velcro 3) sur une pompe à air 4 formant alors socle et assurent un brassage efficace des produits de traitement au moyen d'un diffuseur d'air 5 en céramique, seul matériau offrant à la fois de bonnes performances et une grande longévité sans être attaqué par les produits de traitement. L'air est véhiculé de la pompe 4 au diffuseur 5 par un tuyau 6 maintenu le long de la cuve par des attaches 7 et passant au travers du couvercle 2 par un orifice 8, les orifices Subis permettent eux la sortie de l'air injecté dans la cuve sans pour autant autoriser une quelconque projection des produits de traitement.La pompe à air 4, dont le débit est réglable au moyen du bouton de réglage 9, est alimentée en courant par le secteur 220 v et bénéficie d'une excellente isolation et protection contre les projections de liquide éventuelles, gage d'une sécurité électrique totale. Le diffuseur 5 est fixé au fond du bac 1 par une attache 10.The set consists of a transparent shock plastic container 1 closed by a double cover 2 and which can be fixed (in particular by velcro 3) on an air pump 4 then forming a base and ensuring efficient mixing of the treatment products by means of an air diffuser 5 made of ceramic, the only material offering both good performance and a long service life without being attacked by the treatment products. The air is conveyed from the pump 4 to the diffuser 5 by a pipe 6 maintained along the tank by fasteners 7 and passing through the cover 2 by an orifice 8, the Subis orifices allow them the exit of the injected air in the tank without allowing any projection of the treatment products. The air pump 4, the flow rate of which is adjustable by means of the adjustment knob 9, is supplied with current by the 220 v sector and has excellent insulation and protection against possible liquid splashes, guarantee of total electrical safety. The diffuser 5 is fixed to the bottom of the tank 1 by a clip 10.

Le circuit ou plaque à traiter est inséré dans une glissière amovible en plastique 12 à section en V dont les ailes sont élastiquement déformables et sollicitées l'une vers l'autre afin de retenir par simple pincement les articles 13 qui peuvent ainsi être insérés et retirés très aisément. La glissière 12 coulisse dans un des deux manchons 11 fixés, par exemple par collage, dans la cuve 1. Ce mode d'insertion assure un excellent maintien des articles à traiter et une manipulation extrêmement aisée sans aucun contact avec les produits de traitement, aussi bien en début et fin d'opération qu'en cours de travail pour le contrôle du développement ou de la gravure. La disposition de plusieurs manchons 11 à l'intérieur du bac 1 permet le traitement simultané de plusieurs articles. Les glissières peuvent être des profilés en matière plastique.The circuit or plate to be treated is inserted in a removable plastic slide 12 with a V-section, the wings of which are elastically deformable and urged towards one another in order to hold the articles 13 by simple pinching, which can thus be inserted and removed. very easily. The slide 12 slides in one of the two sleeves 11 fixed, for example by gluing, in the tank 1. This mode of insertion ensures excellent retention of the articles to be treated and extremely easy handling without any contact with the treatment products, also both at the start and end of the operation as during work for development or engraving control. The arrangement of several sleeves 11 inside the tank 1 allows the simultaneous treatment of several articles. The slides can be plastic profiles.

La fixation de la cuve proprement dite sur la pompe-socle par velcro permet un démontage instantané et racilite le rangement de l'ensemble.  The fixing of the tank itself on the pump-base by velcro allows an instant disassembly and racilite the storage of the whole.
