Abstract
Provided are a coating apparatus and a coating system, where the coating apparatus includes: a coating module, the coating module including a coating roller and a coating die, where the coating roller is configured to drive, when rotating, a substrate to move toward the coating die, and the coating die is configured to apply a coating onto the substrate; an error acquisition module having a predetermined distance to the coating roller and configured to acquire a circular run-out error of rotation of the coating roller and transmit the circular run-out error to a linkage module; and the linkage module configured to adjust position of the coating die in real time according to the circular run-out error transmitted to the linkage module, so as to keep a distance between the coating roller and the coating die unchanged.
