[0002] The present application relates to the technical field of transformer production, in particular to an electronic surface adhesive tape winding device for transformer. BACKGROUND

[0003] A transformer is a device that uses the principle of electromagnetic induction to change the alternating voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). In electrical equipment and radio circuits, it is commonly used for voltage conversion, 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 electric potential can be induced in the coil. In these two cases, the value of the magnetic flux does not change, but the amount of magnetic flux intersecting the coil does. This is the principle of mutual induction. A transformer is a device that uses electromagnetic mutual induction to transform voltage, current, and impedance.

[0004] During the operation of the transformer, winding insulation tape is used to wrap the two wires of the transformer together, which can resist high temperature, humidity, corrosion and other factors that affect the external environment, and maintain the normal operation of the transformer, so that the insulation performance of the transformer is effectively protected for a long time. When winding, it should be wound as flat as possible, and attention should be paid to winding as evenly as possible without gaps to ensure the good performance of the winding insulation tape. The existing winding method is generally manual winding, which not only cannot guarantee the uniformity and flatness of the winding, but also has low winding efficiency, increases the winding time and reduces the winding efficiency.
