La présente invention concerne un dispositif pour sceller de manière étanche aux gaz et aux liquides le boîtier d'élément galvanique sous la forme de piles très minces, par soudage aux ultrasons de couches de matière plastique des parties de boîtier.  The present invention relates to a device for sealing in a gas and liquid tight manner the galvanic element housing in the form of very thin batteries, by ultrasonic welding of plastic layers of the housing parts.

Les éléments galvaniques sous la forme de piles minces et plates sont connus et sont par exemple décrits dans le document EP 862 227 Al. Dans de telles piles l'électrode positive et l'électrode négative sont placées avec interposition de séparateur, par exemple entre deux films de matière plastique constituant les parties de boîtier et que l'on relie d'une manière étanche aux gaz et aux liquides. Les films qui forment les parties de boîtier peuvent également être des films de matière plastique métallisée ou des films métalliques, par exemple des films ou feuilles de cuivre dont la zone de bord tournée vers l'intérieur de la pile est revêtue d'une matière plastique permettant le soudage après l'assemblage.  Galvanic elements in the form of thin and flat cells are known and are for example described in document EP 862 227 A1. In such cells the positive electrode and the negative electrode are placed with interposition of a separator, for example between two plastic films constituting the housing parts and which are connected in a gas-tight and liquid-tight manner. The films which form the housing parts can also be films of metallized plastic or metallic films, for example films or sheets of copper, the edge region facing the inside of the stack is coated with a plastic material. allowing welding after assembly.

Pour relier ces parties de boîtier on utilise généralement un procédé de soudage. Selon ce procédé on fixe les parties du composant sur une enclume alignée vers une sonotrode et on soude aux ultrasons.  To connect these housing parts, a welding process is generally used. According to this method, the parts of the component are fixed on an anvil aligned towards a sonotrode and welded with ultrasound.

La présente invention a pour but de rendre ce soudage aux ultrasons fiable même pour des éléments galvaniques très minces.  The present invention aims to make this ultrasonic welding reliable even for very thin galvanic elements.

Ce problème est résolu selon l'invention à l'aide d'un dispositif du type défini ci-dessus, caractérisé en ce qu'il comporte une plaque formant enclume servant d'appui aux pièces à réunir et située en regard de la sonotrode assurant le soudage aux ultrasons, la plaque formant enclume est montée de manière centrée par rapport à la sonotrode et la plaque formant enclume est munie de moyens de guidage et de ressorts dans sa zone de bord.  This problem is solved according to the invention using a device of the type defined above, characterized in that it comprises an anvil plate serving as support for the parts to be assembled and located opposite the sonotrode ensuring ultrasonic welding, the anvil plate is mounted centrally relative to the sonotrode and the anvil plate is provided with guide means and springs in its edge area.

Suivant d'autres caractéristiques avantageuses, - le montage centré est formé d'un appui constitué par une bille, - sur la face supérieure de la plaque formant enclume on a une matière isolante, en particulier une plaque en céramique, - la plaque formant enclume comporte des broches de centrage pour re- cevoir une plaque de centrage.  According to other advantageous characteristics, - the centered mounting is formed by a support constituted by a ball, - on the upper face of the anvil plate there is an insulating material, in particular a ceramic plate, - the anvil plate has centering pins for receiving a centering plate.

Suivant une autre caractéristique le dispositif comporte une mince couche de colle entre la plaque formant enclume et la plaque en matière céramique isolante.  According to another characteristic, the device comprises a thin layer of adhesive between the anvil plate and the insulating ceramic plate.

La présente invention sera décrite ci-après de manière plus détaillée à l'aide des dessins annexés dans lesquels : - la figure 1 est une section du dispositif selon l'invention,  The present invention will be described below in more detail with the aid of the appended drawings in which: FIG. 1 is a section of the device according to the invention,

<Desc/Clms Page number 2><Desc / Clms Page number 2>

- la figure 2 est une vue de dessus du dispositif, - la figure 3 est une coupe partielle du dispositif.  - Figure 2 is a top view of the device, - Figure 3 is a partial section of the device.

Le dispositif selon l'invention se compose pour l'essentiel d'une plaque de support 1 munie en position centrale d'une plaque formant enclume 2 alignée sur une sonotrode 4 placée au-dessus de la plaque formant enclume 2. Le palier est constitué par une bille 3. La plaque formant enclume 2 est montée au niveau de ses bords par des moyens de guidage 6, par exemple des vis à tête et des ressorts de compression 5 qui stabilisent. Un cadre de centrage 7 est fixé à la plaque formant enclume par l'intermédiaire de vis à tête fraisée 12 d'organes d'écartement 13 et de broches de centrage 8. Sur la plaque formant enclume il y a une autre plaque 10 en matière isolante, partiellement en verre ou en une matière céramique ou encore une plaque d'acier. Entre cette plaque et la plaque formant enclume 2 on a une mince couche de colle. La couche de colle assure le découplage pour que le siège du palier centré ou de la bille 3 ne soit pas détruit par l'action des ultrasons.  The device according to the invention essentially consists of a support plate 1 provided in the central position with an anvil plate 2 aligned on a sonotrode 4 placed above the anvil plate 2. The bearing consists by a ball 3. The anvil plate 2 is mounted at its edges by guide means 6, for example head screws and compression springs 5 which stabilize. A centering frame 7 is fixed to the anvil plate by means of countersunk-head screws 12 of spacer members 13 and centering pins 8. On the anvil plate there is another plate 10 made of material. insulating, partially made of glass or a ceramic material or a steel plate. Between this plate and the anvil plate 2 there is a thin layer of glue. The layer of adhesive ensures decoupling so that the seat of the centered bearing or of the ball 3 is not destroyed by the action of ultrasound.

On place dans le cadre de centrage 7, la combinaison de films non représentée en détail et qui constitue l'élément galvanique puis on soude le long du contour 14. La sonotrode 4 est centrée au-dessus de la bille 3.  The combination of films, not shown in detail and which constitutes the galvanic element, is placed in the centering frame 7 and then welded along the contour 14. The sonotrode 4 is centered above the ball 3.

En position de repos la plaque est montée libre par rapport au siège à bille, contre la butée des têtes de vis 6. Ces vis à tête 6 sont définies pour être grossièrement alignées par rapport à la sonotrode 4. Pour souder, la sonotrode 4 arrive sur la combinaison de films placée dans le logement du cadre de centrage 7 et qui constitue la pile ; on presse alors la plaque formant enclume 2 dans le siège de la bille 3. Comme la bille 3 est centrée par rapport à la sonotrode 4, la plaque formant enclume 2 s'aligne exactement par rapport à la sonotrode 4. La plaque formant enclume 2 compense les défauts de parallélisme dans un domaine par exemple de 1/100 mm. L'alignement grossier réalisé par les moyens de guidage ou les vis à tête 3 évite un basculement trop important de la plaque formant enclume 2 de sorte que les éléments de piles ne soient soumis à aucune force qui pourrait les faire coulisser l'un par rapport à l'autre.  In the rest position the plate is mounted free relative to the ball seat, against the stop of the screw heads 6. These head screws 6 are defined to be roughly aligned with respect to the sonotrode 4. To weld, the sonotrode 4 arrives on the combination of films placed in the housing of the centering frame 7 and which constitutes the stack; the anvil plate 2 is then pressed in the seat of the ball 3. As the ball 3 is centered relative to the sonotrode 4, the anvil plate 2 is aligned exactly with respect to the sonotrode 4. The anvil plate 2 compensates for parallelism defects in a range, for example of 1/100 mm. The rough alignment achieved by the guide means or the head screws 3 prevents the anvil plate 2 from tilting too much so that the battery cells are not subjected to any force which could cause them to slide relative to one another. to the other.

Le dispositif selon l'invention permet un soudage précis de pièces très minces comme par exemple le scellement de piles plates au lithium prévues pour des cartes de circuits électroniques ayant par exemple une épaisseur de 0,4 mm.  The device according to the invention allows precise welding of very thin parts, for example the sealing of flat lithium batteries intended for electronic circuit boards having for example a thickness of 0.4 mm.
