Abstract
Disclosed herein is a bonded-type laminated core member manufacturing apparatus comprising an adhesive application unit to apply an adhesive to a material being continuously transferred, and a laminating unit to integrate laminar members laminated within a laminating hole by blanking the material, a laminated core member being manufactured by interlayer adhesion between the laminar members, wherein the laminating unit includes a high-frequency heater to harden the adhesive located between the laminar members, the high-frequency heater including a coil wound on the circumference of a hardening hole which accommodates the laminar members and forming a passage of high-frequency current. In accordance with the present invention, the adhesive is rapidly hardened by high-frequency induction heating and thus the integration time of the laminated core member is shortened, and accuracy of the laminating unit, which integrates the laminar members, i.e., straightness of the laminating hole to pass the laminar members, is stably maintained and, thus, misalignment of the laminated core members is prevented and management of product quality is facilitated.
