Coating device and coating method

The invention discloses a coating device and a coating method.The coating device comprises a rack, a coating module, a first driving mechanism and a second driving mechanism, the rack comprises a base and a coating roller, the base is movably installed on the rack, and the first driving mechanism drives the coating module to move in the first direction and the second direction opposite to the first direction; and the second driving mechanism is used for providing thrust towards the first direction or the second direction for the base, and the coating method is executed by adopting the coating device. Movement of the coating module in the first direction or the second direction is achieved through driving of the first driving mechanism, and the second driving mechanism is connected with the base and used for applying thrust towards the first direction or the second direction to the coating module so as to provide assistance in the starting stage of the coating module and provide resistance in the braking stage
