Background The inkjet printing technology refers to a technology that an inkjet printing device uniformly ejects ink droplets onto a printing medium through nozzles on a nozzle to obtain images or characters, and the printing medium is generally two-dimensional, but with the development of technology and the growing demand for printing the surface of a three-dimensional product, more and more occasions need to print the surface of the three-dimensional product, for example, in the actual manufacturing process of a square battery case serving as a three-dimensional product, an ink layer obtained by printing ink on the surface of the battery case is required to form an insulating layer such as an insulating blue film layer so as to cover the whole surface, thereby reducing the risks of short circuit and fire between the battery cases. In the manufacturing process of the square battery case, welding, stamping and other processing technologies are needed to form the surface of the corner at the intersection of two adjacent square surfaces, the surface of the corner has larger bending degree as the transition between two surfaces, so that roughness is higher, and some salient points are easy to generate at the corner, when ink is printed on the surface of the corner with the salient points, because of the surface tension and the liquid shrinkage effect, the gap between the salient points can lead the ink serving as liquid to be more prone to be gathered on the salient points without smoothly transiting to the lower part or the periphery, so that the gap between the salient points can lead the liquid to generate local fracture and can not be continuously spread, and the defect that the integrity and the uniformity of an ink layer are poor due to the fact that the roughness exists at the corner, namely, the insulation blue film layer wrapping the whole surface of the battery case is difficult to form, so that a plurality of gaps exist on the cured insulation blue film layer, the risk of short circuit and fire between the battery cases is increased, and the safety of the battery is further reduced.
