This master’s thesis deals with the rationalization of the winding process in the production of solenoids with a focus on increasing the efficiency of assembly and reducing the scrap rate. The aim of the thesis was to propose a technical solution leading to the improvements of the production process. It summarizes basic knowledge about the design and function of spindles, also used in winding processes, and also deals with the basic characteristics of solenoids. Focus on the design of a type of winding spindles for the production of solenoids, which replaces the original threaded design with an expansion sleeve and a locking element, and on the design of a pressing fixture for mounting pins into the coil frame. The proposed solutions were verified in real serial production, where assembly time was shortened, the number of production operations was reduced and the scrap rate was reduced. The thesis also includes an economic evaluation based on real operating data, which confirms an approximate payback period of two years. The results demonstrate the benefit of the proposed measures to the rationalization of the winding process.
