Description

Technical Field

[0001] The utility model relates to the technical field of transformer production, in particular to a device for attaching copper foil to a magnetic core. Background Art

[0002] A transformer is a device that transforms AC voltage, current, and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), inducing a voltage (or current) in the secondary coil. A transformer consists of an iron core (or magnetic core) and a coil. The coil has two or more windings: the winding connected to the power supply is called the primary coil, and the remaining windings are called the secondary coils. In a generator, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electric potential is induced in the coil. In both cases, the value of the magnetic flux remains constant, but the amount of magnetic flux intersecting the coil changes. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance. Copper foil has low surface oxygen content, can adhere to a variety of substrates, and has a wide operating temperature range. It is primarily used for electromagnetic shielding and antistatic applications. Placing conductive copper foil on the substrate, combined with the metal substrate, provides excellent conductivity and electromagnetic shielding. To mitigate interference and improve power supply reliability, transformers often use copper foil on the outer surface of the magnetic core. During the production process of transformer copper foil, misalignment is likely to occur, thus affecting the qualified rate of copper foil. Utility Model Content
