Description

technical field [0001] The invention relates to the technical field of production of a transformer non-gold alloy magnetic core material, in particular to a fully automatic transformer magnetic core strip winding device. Background technique [0002] The structure of transformers widely used in modern industry is mainly composed of mutually insulated primary windings, secondary windings, magnetic cores, frames, shells, terminals and other components. Winding magnetic cores with amorphous alloy strips is a relatively advanced preparation method for transformer cores. Amorphous alloy strips are usually prepared by single-roll quick quenching method: first, the amorphous alloy strips need to be put into the furnace Carry out melting and calcination, then pour the fully fused amorphous alloy solution onto a cooling roll that rotates rapidly and has a lower surface temperature, the molten amorphous alloy material contacts the cooling roll and cools rapidly to form an amorphous al...

Winding magnetic cores with amorphous alloy strips is a relatively advanced preparation method for transformer cores. Amorphous alloy strips are usually prepared by single-roll quick quenching method: first, the amorphous alloy strips need to be put into the furnace Carry out melting and calcination, then pour the fully fused amorphous alloy solution onto a cooling roll that rotates rapidly and has a lower surface temperature, the molten amorphous alloy material contacts the cooling roll and cools rapidly to form an amorphous alloy strip, and then the amorphous alloy The alloy strip is wound into a closed ring shape. The conventional amorphous alloy strip winding is mainly automatic mechanical winding and manual winding. The manual winding method is labor-intensive and low in efficiency, while the conventional The automatic winding machine needs to cut off the continuous transformer magnetic core strip manually after the winding is completed, and stick the end of the magnetic core strip connected to the magnetic core part after cutting to the surface of the magnetic core roller. The above operation method is laborious. High strength and low operating efficiency; in addition, the conventional automatic winding machinery is not accurate in judging the quantitative end point of transformer magnetic core strip winding, thus increasing the screening workload of subsequent quality control links
