Description

TECHNICAL FIELD

The core function is to improve the assembly efficiency, ensure the product consistency and electrical performance, and is widely used in the power equipment manufacturing industry, which includes core assembly device, winding assembly device and overall assembly and auxiliary equipment, etc. When the transformer assembly device assembles the core, it mainly stacks, positions and fastens silicon steel sheets such as E core, I core and ring core according to the design rules to form a core body with low magnetic resistance and high magnetic conductivity, which lays the foundation for subsequent winding assembly and magnetic circuit construction, directly affects the loss, efficiency and operation stability of the transformer, and is one of the core processes of transformer production.

[0003] However, before the traditional transformer assembly device assembles the core, the laminations need to be temporarily stored in the material collecting bin.
