(EN) BATTERY CELL MANUFACTURING DEVICE USING INDUCTION HEATING
(FR) DISPOSITIF DE FABRICATION D'ÉLÉMENT DE BATTERIE UTILISANT UN CHAUFFAGE PAR INDUCTION
Abstract
(EN)
The present disclosure provides a battery cell manufacturing apparatus for forming a sealing surplus portion by thermally fusing an outer periphery of a pouch type case by using induction heating, and the apparatus includes a cradle configured to fix and mount a battery cell; one or more induction heating coils formed by winding an electrical wire at least one time at a position corresponding to the outer periphery to generate an induced current in the outer periphery of the pouch type case on which the sealing surplus portion is to be formed; a power supply configured to supply an alternating current to the induction heating coils; and at least two pressing members configured to press both sides of the outer periphery of the pouch type case on which the sealing surplus portion is to be formed, wherein the outer periphery of the pouch type case is induction-heated by a magnetic field generated in the induction heating coils and up to a temperature at which heat fusion is possible to form the sealing surplus portion.

La présente invention concerne un dispositif de fabrication d'élément de batterie utilisant un chauffage par induction pour lier thermiquement la périphérie externe d'un boîtier de type poche, formant ainsi une partie d'étanchéité excédentaire. Le dispositif de fabrication d'élément de batterie est caractérisé en ce qu'il comprend : un support pour fixer et monter un élément de batterie ; au moins une bobine de chauffage par induction formée par enroulement d'un fil électrique au moins une fois dans une position correspondant à la périphérie externe de telle sorte qu'un courant d'induction peut être généré sur la périphérie externe du boîtier de type poche sur lequel la partie d'étanchéité excédentaire doit être formée ; une partie d'alimentation électrique pour fournir un courant alternatif à la bobine de chauffage par induction ; et au moins deux éléments de compression pour comprimer, des deux côtés, la périphérie externe du boîtier de type poche sur lequel la partie d'étanchéité excédentaire doit être formée, la périphérie externe du boîtier de type poche étant chauffée par induction à la température à laquelle la liaison thermique pour former la partie d'étanchéité excédentaire est possible à l'aide d'un champ magnétique généré dans la bobine de chauffage par induction.
