Ultrasonic Knife Geometry for Clean Secondary Battery Electrode Cutting

The patent replaces the conventional mechanical cutting system with an ultrasonic cutting system. The ultrasonic vibration module generates high-frequency vibrations that are transmitted to the cutting member, enabling cutting through vibrational energy rather than purely mechanical force. This substitution prevents blade blunting by using vibration-assisted cutting that reduces friction and heat generation, thereby maintaining cutting efficiency over extended periods.

The patent directly applies mechanical vibration through the ultrasonic vibration module that generates high-frequency oscillations in the cutting member. This vibration assists the cutting process by reducing contact time between the cutting member and sheet material, minimizing adhesion of scattering matters, and preventing blade blunting even during repeated cutting operations, thus resolving the contradiction between productivity and blade sharpness.

The ultrasonic vibration module generates high-frequency vibrations in the cutting member that reduce the contact time between the cutting edge and sheet material. This vibrational action prevents scattering matters from adhering to the cutting member surface, maintaining clean cut surfaces and high manufacturing precision while sustaining productivity through continuous operation.

By replacing conventional mechanical cutting with ultrasonic vibration-assisted cutting, the system eliminates the friction and heat that cause material adhesion. The vibrational energy enables clean separation of material without the scraping action that generates scattering matters, thereby maintaining cut surface quality during high-productivity repeated cutting.

The patent merges the cutting member with an ultrasonic vibration module into an integrated cutting system. This combination allows the cutting member to receive vibrational energy directly, enabling it to maintain sharp edges and prevent material adhesion without requiring separate blade replacement mechanisms or complex cooling systems, thus achieving high cut surface quality with moderate device complexity.

The cutting member is designed to serve multiple functions: it performs the primary cutting action while simultaneously receiving ultrasonic vibrations to prevent adhesion and maintain edge sharpness. This multi-functionality allows a single component to achieve both high productivity and high manufacturing precision without requiring additional separate systems.
