In accordance with the height of the lithium battery, the measuring column 7-6 and the measuring frame 7-7 are observed during the continuous movement. When there is a protrusion, the measuring column 7-6 will move upward to facilitate the viewing of the protruding part. When repair is needed, according to the surface height of the lithium battery, the adjusting screw 6-1 is turned to control the leveler 6-5 to fit the normal coating surface of the lithium battery. Then the driving motor 6-4 is started to drive the driven gear 6-6 through the driving gear 6-7 to rotate the leveler 6-5 and cooperate with the transverse movement to gradually level the protruding part as it moves.
