This utility model discloses an online roller cleaning device for pressing electrodes, relating to the technical field of electrode processing equipment. It solves the problems of incomplete cleaning and localized particle adhesion to the rollers inherent in existing technologies. The device includes a frame with upper and lower rollers for pressing electrodes. A laser cleaning component and a protective cover are also connected to the frame. The laser cleaning component cleans the coating material on the corresponding roller using laser light. The protective cover has slits for the laser to pass through and slides parallel to the laser irradiation direction, connected to the frame. One side of the protective cover covers the corresponding roller, and the sliding path of this side's axis of symmetry is arranged radially along the corresponding roller. This device improves the cleaning effect of the coating material on the rollers. By replacing the scraper mechanism with a laser cleaning device, and placing the laser cleaning device below the lower roller and above the upper roller, the laser energy can be adjusted to remove the coating material adhering to the rollers without damaging them.
