Background Art

[0002] Power transmission and distribution is an important industry related to the people's livelihood. In the power transmission and distribution process, transformers of various capacity levels are indispensable. In the power transmission and distribution process of transformers of various capacity levels, energy conservation and fully reducing the power grid's own operating energy consumption have always been the direction of continuous exploration and efforts by the power industry. In terms of the operating efficiency and energy consumption loss of the transformer itself, in addition to adopting a more optimized core structure, silicon steel sheet material and splicing method, exploring the additional stress, iron loss and random error caused by manual secondary iron stacking due to multiple handling and knocking in the traditional core production process has become a problem that needs to be solved in the development of the core production industry.

[0003] In recent years, with the traditional manufacturing industry vigorously carrying out digital transformation, continuously improving production efficiency, reducing labor costs, and fully tapping the benefits of data, it is particularly urgent to subvert the traditional labor-intensive production model of the transformer manufacturing industry. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method that can realize point-to-point absolute position transmission of the yoke iron sheets, phase column side column sheets, and middle column sheets of the iron core formed by intelligent cutting from the finished silicon steel coil strip. After being transmitted to the set position, the set position of each finished iron sheet is automatically stacked and stacked through the intelligent stacking host.
