2 DEVICE FOR REMOVING COATING MATERIALS WHEN CUTTING JELLY ROLLY IN THE JELLY ROLL WINDING SYSTEM OF ELECTRIC DOUBLE LAYER CAPACITORS

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a foreign matter removing device generated in a process of winding a battery roll in a secondary battery winding system. In the system including the electrode winding process of the secondary battery, the surface of the electrode and the separator is coated with a ceramic, so that the ceramic powder is blown when the cutting blade cuts on the ceramic coated surface. If it is difficult to form a pedestal by the backside of the electrode in the winding structure of the electrode plate, when the blade is cut in the space and the electrode plate is cut, the ceramic powder is accumulated in the peripheral machinery and mechanism part repeatedly. Therefore, there is a problem in the operation of the machine, and it is often necessary to disassemble and clean the relevant part, thereby deteriorating the productivity. The present invention relates to a method for removing foreign matter scattered during winding process when a battery roll (jelly roll) is manufactured, and particularly, when a separating film is cut, a coating material can be removed A suction means for sucking the coating material scattered on the central axis of the winding unit and discharging the coating material to the outside of the system is formed so that the coating material separated from the electrode and the separation membrane is not accumulated in the system, A system for removing foreign substances generated in a process of winding a battery roll in a secondary battery reeling system.
