Description

Ribbon wire coating device

The present invention relates to a ribbon wire coating apparatus capable of precisely and uniformly enamelling a ribbon wire of an electric conductor used in various electronic products and the like.

The ribbon wire means that a round or square wire rod is finely rolled using a rolling mill, and the ribbon wire is enamelled on the surface through a coating apparatus.

Conventionally, a ribbon wire drawn from a drawing machine is softened, the softened ribbon wire is drawn into a coating portion, coated with enamel, and then coated and then dried at a uniform temperature to coat the surface of the ribbon wire with enamel.

Specifically, it includes a supply part for supplying a ribbon wire for enamel coating, a coating part for coating enamel on the surface of the ribbon wire, a drying part for heating and drying the coated enamel, and a winding part for winding the dried wire on the bobbin .

The coating method of the ribbon wire was performed by a method of spraying through a spray nozzle and a method of coating the surface by immersing or passing through a container containing enamel.

However, since the ribbon wire is rolled, the method of spraying enamel on one side of the upper, lower, right and left sides can not uniformly coat the surface of the ribbon wire. In the immersion method, too much enamel is deposited on the surface, There was a problem of enormous waste of course as well as difficulty.
