Description

Technical Field

[0001] The utility model relates to the technical field of film laminating devices, and more specifically, to a film laminating device for a patch transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). In electrical equipment and wireless circuits, it is commonly used for stepping up or down voltages, impedance matching, safety isolation, etc. In a generator, whether the coil moves through the magnetic field or the magnetic field moves through the fixed coil, an electromotive force can be induced in the coil. With the development of ultra-large-scale circuits and system integration, as well as the high-density surface mounting of printed circuit boards, the emergence of patch transformers provides a feasible path for the miniaturization of power systems. Conventional patch transformers are made using plastic skeletons, and enameled wires are wound around the plastic skeletons. After production, the plastic skeleton and the wound enameled wires together form a patch transformer. During the production process of patch transformers, it is necessary to laminate the coils to protect them. Existing laminating equipment generally has a fixed structure and cannot be adjusted according to coils of different specifications.
