the spraying steps comprise:
s1: the feeding device clamps one wall surface of the lithium battery and moves the lithium battery to a spraying position;
s2: the side spraying device positioned at the periphery of the spraying position moves towards a position close to the outer side wall of the lithium battery and simultaneously sprays the periphery of the lithium battery;
s3: when the lithium battery has a corner cambered surface, the adjacent side spraying devices can spray simultaneously or spray in a staggered manner;
s4: the feeding device can drive the lithium battery to vertically reciprocate;
s5: when the insulating ink layer of the lithium battery reaches a preset thickness, the feeding device drives the lithium battery to move to the position of the curing device and fixes the ink on the peripheral wall of the lithium battery.
According to the technical scheme, the feeding device adopts a vertical lifting structure, so that the peripheral wall of the lithium battery can be sprayed at the same time, the spraying time and the equipment volume are smaller compared with the existing equipment, the strength, the shearing force and the insulating blind area of the sprayed insulating paint surface are smaller, and the processing efficiency and the product precision degree of the lithium battery are effectively improved.
