Title:
BATTERY CELL MANUFACTURING DEVICE USING INDUCTION HEATING
Document Type and Number:
WIPO Patent Application WO/2018/128302
Kind Code:
A2
Abstract:
The present invention provides a battery cell manufacturing device using induction heating to thermally bond the outer periphery of a pouch-type case, thereby forming a surplus sealing portion. The battery cell manufacturing device is characterized by including: a support for fixing and mounting a battery cell; at least one induction heating coil formed by winding an electric wire at least once at a position corresponding to the outer periphery so that an induction current can be generated on the outer periphery of pouch-type case on which the surplus sealing portion is to be formed; a power supply part for providing an alternating current to the induction heating coil; and at least two compressing members for compressing, from both sides, the outer periphery of pouch-type case on which the surplus sealing portion is to be formed, wherein the outer periphery of the pouch-type case is inductively heated to the temperature at which the thermal-bonding for forming the surplus sealing portion is possible using a magnetic field generated in the induction heating coil.
