s1: putting the electrode sheet base material released from the unreeling device into the box body (1) from the electrode sheet base material inlet (2), tightly coiling the electrode sheet base material on the two groups of carrying rollers (13) and the back roller (19) in an S shape, and finally releasing the electrode sheet base material from the electrode sheet base material outlet (3) to be connected with a reeling mechanism on electrode sheet drying;
s2: pouring the slurry to be coated into a slurry coating collecting box (4), screwing a collecting box cover (5), controlling the rotation of a first motor (6) through a controller (22), enabling a stirring rod (7) to further stir the slurry, enabling the slurry to flow to the surface of a coating roller (12) through a guide hole (8), controlling the rotation of a second motor (20) through the controller (22) to enable the coating roller (12) to rotate, and enabling the slurry to be adhered on the coating roller (12);
s3: according to the coating requirement during battery production, the controller (22) controls the fourth motor (23) to rotate so as to enable the scraping wheel (10) to rotate, thereby adjusting the gap between the scraping wheel (10) and the coating roller (12) and adjusting the thickness of the slurry on the coating roller (12);
s4: and then the operation of the electric push rod (16) is controlled by the controller (22), the distance between the back roller (19) and the coating roller (12) is further adjusted, so that the slurry on the coating roller (12) is coated on the electrode slice substrate conveyed on the back roller (19), and the coating of the slurry on the battery motor slice and the adjustment of the coating thickness are completed.
