Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a coil winding device in a transformer. Background Art

[0002] The transformer consists of an iron 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 secondary coils. It can transform AC voltage, current and impedance. The simplest iron core transformer consists of an iron core made of soft magnetic material and two coils with unequal numbers of turns wrapped around the iron core.

[0003] For example, Chinese patent CN220420436U proposes a transformer coil winding mechanism, including a substrate, a winding assembly and a clamping assembly, wherein the winding assembly is arranged on the substrate and the rotation direction intersects with the width direction of the substrate, and is used to wind the coil of the magnetic core of the transformer; the clamping assembly is arranged on both sides of the winding assembly and can be moved along the length direction of the substrate to switch to a clamped state or a loosened state, when the clamping assembly switches to the clamped state, the magnetic core is clamped and fixed in the winding direction of the winding assembly; when the clamping assembly switches to the loose position, the magnetic core is released and loosened in the winding direction of the winding assembly. The clamping spacing is adjusted by the clamping assembly, so that magnetic cores of different sizes can be clamped and fixed.

[0004] Although the above patent can achieve clamping and fixing of magnetic cores of different sizes, it cannot achieve adjustment of tension during the winding process. In actual production, in order to ensure the uniformity of the coil on the magnetic core, workers are often required to manually adjust the tightness of the coil, which leads to reduced production efficiency.

[0005] Based on this, the utility model designs a coil winding device in a transformer to solve the above problems. Utility Model Content
