The utility model discloses a flexible intelligent lamination production system for a transformer iron core. The system comprises a storage round-trip turnover stepping conveying platform (1), a silicon steel sheet taking and fragmenting multi-mechanical-arm platform (2), a silicon steel sheet conveying, leading-in, correcting and positioning platform (3), a silicon steel sheet multi-mechanical-arm flexible collaborative stacking platform (4) and a silicon steel sheet turnover output platform (5) which are sequentially arranged into a line. The terminal of the storage round-trip turnover stepping conveying platform 1 is located below the silicon steel sheet taking and slicing multi-mechanical-arm platform; the silicon steel sheet taking and slicing multi-mechanical-arm platform, the silicon steel sheet conveying, guiding, correcting and positioning platform, the silicon steel sheet multi-mechanical-arm flexible cooperative stacking platform and the silicon steel sheet overturning and outputting platform are located in a main rack (6), and an outer side rail (601) and an inner side rail (602) are arranged on the main rack in the long axis direction. According to the utility model, the mechanical-electrical-automatic integration of the whole process from feeding to lamination and turnover output of transformer iron core lamination can be realized, and the lamination precision andthe lamination efficiency of the transformer are improved.
