Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer manufacturing, in particular to a transformer magnetic core coil outer copper foil component. Background Art
[0002] The transformer core coil outer copper foil assembly is composed of a foil supply device and a foil winding device. The copper foil needs to be cleaned before winding it. The cleaning method is generally to scrub the oil stains on the surface with a brush. The copper foil will be squeezed during the scrubbing process, and the surface of the copper foil will be deformed and uneven during the squeezing. Therefore, the copper foil needs to be flattened before winding. The existing technology generally achieves the flattening action by two rollers rolling against each other. When the thickness of the copper foil changes, the operator adjusts the gap between the two rollers to squeeze the copper foil. The size of the gap often needs to be smaller than the thickness of the copper foil. In the actual production process, the copper foil will be squeezed and deformed, affecting the production quality. For this reason, we propose a transformer core coil outer copper foil assembly. Utility Model Content

[0013] (1) The transformer core coil is wrapped with a copper foil assembly.

At this time, the gap between the second rotating roller and the first rotating roller is smaller than the thickness of the copper foil. When the copper foil enters between the second rotating roller and the first rotating roller, it squeezes the second rotating roller, causing the second rotating roller to move upward. In actual use, the second rotating roller can maintain a stable pressure without causing extrusion deformation of the copper foil due to excessive pressure, thereby improving production quality.
[0014] (2) The transformer core coil is wrapped with a copper foil assembly.

The sliding sleeve is moved on the fixed column by rotating the screw rod, and the sliding sleeve can be quickly disassembled and replaced. The copper foil and the prepreg DMD wound on the first rotating column are respectively guided through two shunt chambers. When cut by a cutting knife, one end of the copper foil and the prepreg DMD wound on the first rotating column will not droop completely, which is convenient for subsequent re-winding work and easy to use.
