Embodiment approach 1

[0037] Fig. 1 has shown the perspective view of the first embodiment that is used for electric wire painting device of the present invention; figure 2 An enlarged cross-sectional view showing a state in which the varnish is applied to the outer surface of the electric wire by the dripping of the varnish from the dripping nozzle of the dripping device of the first embodiment; image 3 An enlarged sectional view showing a state of a typical electric wire forming a varnish insulating layer; and FIG. 4 showing a perspective view of a second embodiment of the apparatus for varnishing an electric wire of the present invention.

[0038] In Figure 1 to image 3 In , the reference number 1 represents - a wire moving at the desired speed. In this embodiment, said wire 1 has a circular cross-section and a diameter of 0.01 mm to 3.00 mm, preferably a diameter of 0.2 mm to 2.50 mm. The electric wire 1 is made of metal such as aluminum or its alloys, or iron, gold or other conductors, whi...

specific Embodiment 1

[0077] The electric wire having an outer diameter φ of 1.00 mm is fed by the rolling of the conveying roller (not shown), and the electric wire is taken up by the take-up roller (not shown), and the electric wire moves at a speed of about 20 m / min. By turning the working handle 12 of the dropping device 8 , the storage tank 15 is filled with a suitable amount of varnish W to drop drop by drop from the dropping nozzle 11 onto the electric wire 1 moving along the moving direction A.

[0078] In this embodiment, the varnish W is composed of a resin component and a solvent, the resin component is polyamide resin, epoxy resin, polyimide resin, etc., or a compound of two resins, and the solvent is cresol, xylene, ( Mixed) xylene, ethylbenzene, phenol, methanol, ethanol, water, etc. In this embodiment, the varnish W is composed of 10-30% by weight of the resin component and 70-90% by weight of the solvent. In this embodiment, when the liquid temperature of the varnish is 20°C-30°C, ...

Embodiment approach 2

[0084] Figure 4 shows a second embodiment of the device for applying varnish to electrical wires according to the invention. In FIG. 4 , like reference numerals refer to like elements in FIG. 1 . In the present embodiment, an insulating layer P of varnish W is formed on the outer surfaces of a plurality of electric wires 1, 1, . . . which are arranged to be movable at a predetermined speed. The device comprises, arranged at a lower position in the direction of movement of the arrow A, a trough-shaped container 2, 2, ... for the individual wires, and a dripping device on said container 2, 2, ... 8, 8, ... to correspond to the plurality of electric wires 1, 1, ... and for dripping and applying a predetermined amount of varnish on the outer surface of each of the plurality of electric wires 1, 1, ... W, and dripping devices 8, 8, . . . each provided with a flow rate adjusting portion 9. Each of the plurality of wires 1, 1, . . . has an outer diameter of 0.01 mm-3.00 mm, prefera...

Abstract

An electric wire 1 is moved in a moving direction at a desired speed. An insulating layer of varnish is formed on the outer surface of the electric wire 1 by a device for applying the varnish. The device includes a rough-like container 2 and dropping means 8. The rough-like container 2 is located below the electric wire 1 in the moving direction. The dropping means 8 is located for the electric wire above the container. Adesired quantity of varnish is dropped from the dropping means 8 toward the outer surface of the electric wire 1 through a flow rate adjusting portion. The flow rate of the varnish is adjusted by the flow rate adjusting portion 9.

Description

technical field [0001] The present invention relates to an electric wire varnishing apparatus and method thereof, and more particularly, the present invention relates to an apparatus for forming an insulating layer having stable electrical and thermal insulation by applying a minimum necessary amount of varnish to the outer surface of an electric wire and method without changing the mixing ratio of the resin and solvent in the varnish and with high productivity. Background technique [0002] A conventionally known method for forming an electrical insulating layer or a surface finish on the outer surface of an electric wire is to immerse the electric wire in an insulating liquid such as varnish by passing the electric wire through a container containing the insulating liquid so that the varnish is absorbed by the viscosity of the varnish. Applied on the outer surface to form an insulating layer, and drying said varnish insulating layer by passing the electric wire through a d...
