Summary:The invention relates to the technical field of magnetic core preparation, in particular to a preparation method and device for an insulated coated amorphous nanocrystalline strip. The method comprises the steps that S1, the surface of an original magnetically soft alloy strip is continuously and evenly coated with a polyvinylpyrrolidone solution, and a magnetically soft alloy strip coated with polyvinylpyrrolidone is obtained; s2, the magnetically soft alloy strip coated with polyvinylpyrrolidone is continuously immersed in a tetrabutyl titanate solution to be subjected to water bath for a certain time, and a magnetically soft alloy strip with a titanium dioxide coating layer is obtained; and S3, the magnetically soft alloy strip with the titanium dioxide coating layer is cleaned and dried, and the magnetically soft alloy strip with the insulation coating layer is obtained. According to the invention, the surface of the strip is preferentially coated with a TiO2 insulating layer, so that the problem that abs
