The iron core is a basic component of the transformer and is a magnetic circuit and a framework of the transformer, and the quality of the iron core plays a decisive role in the performance of the transformer. The iron core is formed by accumulating silicon steel sheets with different widths and thicknesses of 0.2-0.35mm layer by layer, and has various structural forms, such as a single-phase three-column, a three-phase five-column and the like. The silicon steel sheets can be manually stacked, and an iron core automatic stacking device with higher efficiency can also be used for automatic stacking.

At present, the manual stacking procedure of the domestic silicon steel sheets is finished in a mode of one group of six persons, and because the silicon steel sheets are large and soft, the silicon steel sheets are very easy to be scratched and cut by sharp corners during sheet taking, the repeated stacking times of operators are more, the efficiency is low, the iron core stacking quality is unstable, and the labor intensity is very high.
When automatically stacking the silicon steel sheets, the sucking disc device adsorbs the silicon steel sheets from the raw material rack, lifts to move to a position where products need to be stacked, automatically identifies, positions and releases, and automatically detects and corrects the seam. Because the silicon steel sheet is long strip-shaped, the thickness is very thin, and the specification size and the shape are relatively complex, the sucking disc device is easy to bend in the process of grabbing the silicon steel sheet in the automatic iron core stacking process, so that the positioning is inaccurate or the silicon steel sheet is damaged. Meanwhile, when the silicon steel sheets are sucked by the sucking disc, the situation that a plurality of silicon steel sheets are sucked at one time often occurs, so that the stacking sequence of the silicon steel sheets is wrong, and the product quality is influenced. Therefore, a sucking disc device which is suitable for automatically overlapping the iron core and used for grabbing and releasing the silicon steel sheet needs to be designed, and the silicon steel sheet can be accurately grabbed and placed.
