Title:
LAMINATED IRON CORE PRODUCTION DEVICE, LAMINATED IRON CORE, AND LAMINATED IRON CORE PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/172451
Kind Code:
A1
Abstract:
A laminated iron core production device that layers a plurality of punched members that have been punched from a plate-shaped member (MS). The laminated iron core production device has a transport means that transports the plate-shaped member (MS), lifters (146) that support the plate-shaped member (MS) as transported by the transport means, a liquid material supply unit (143) that deposits a liquid material on an area of one principal surface of the plate-shaped member (MS) as transported by the transport means that is to become a punched member, and a punching unit (D42) that, after the liquid material has been deposited, punches the plate-shaped member (MS) and forms a punched member. The liquid material supply unit (143) deposits the liquid material on the plate-shaped member (MS) so as to avoid contact areas (S1–S4) that, of the area of the plate-shaped member (MS) that is to become a punched member, are areas at which the plate-shaped member (MS) is in contact with lifters (146) that are downstream of where the liquid material supply unit (143) is to deposit the liquid material and upstream of the punching unit (D42).
