Abstract

Provided is a coating device and a method capable of coating a conductor of a plurality of electrical wires with coating material with simple configuration and of coating without exposing the conductor. A nozzle and a coating area of a terminal-equipped electrical wire are applied to voltage by a voltage applying unit such as to be electrified with polarity different from each other, and jetting jet liquid forms jet liquid over the whole coating area, forms the coating layer with anticorrosion material on a surface of the terminal-equipped electrical wire, and coats the coating area including a conductor with anticorrosion material without being exposed. Furthermore, it is possible to allow the nozzle jet the jet liquid and to move the nozzle in an arranging direction of the terminal-equipped electrical wire, and also to coat the coating area of the terminal-equipped electrical wire with anticorrosion material.

First claim

1 . A coating device for coating an exposed conductor of an electrical wire with coating material, the coating device comprising:
a holder for arranging and holding a plurality of electrical wires; a jetting unit including a jetting outlet made of metal arranged spaced apart from the holder, and jetting liquid including the coating material out of the jetting outlet; a voltage application unit for applying a voltage to the jetting outlet and the conductor, and electrifying the jetting outlet and the conductor; a moving unit for relatively-moving the jetting outlet and the holder along an arrangement direction of the plurality of electrical wires; a controller, while letting the jetting outlet jet the liquid, allowing the moving unit to relatively-move the jetting outlet and the holder along the arrangement direction.

2 . The coating device according to claim 1 , wherein the electrical wire is an aluminum electrical wire.

3 . The coating device according to claim 1 , wherein the voltage application unit applies voltage such that the jetting outlet and the conductor are each electrified to have polarity different from each other.

4 . The coating device according to claim 2 , wherein the voltage application unit applies voltage such that the jetting outlet and the conductor are each electrified to have polarity different from each other.

5 . The coating device according to claim 1 , wherein the moving unit relatively-moves the jetting outlet and the holder along a longitudinal direction of the electrical wire.

6 . The coating device according to claim 2 , wherein the moving unit relatively-moves the jetting outlet and the holder along a longitudinal direction of the electrical wire.

7 . The coating device according to claim 3 , wherein the moving unit relatively-moves the jetting outlet and the holder along a longitudinal direction of the electrical wire.

8 . The coating device according to claim 4 , wherein the moving unit relatively-moves the jetting outlet and the holder along a longitudinal direction of the electrical wire.

9 . The coating device according to claim 1 , wherein the coating material is anticorrosion material.

10 . The coating device according to claim 2 , wherein the coating material is anticorrosion material.

11 . The coating device according to claim 3 , wherein the coating material is anticorrosion material.

12 . The coating device according to claim 4 , wherein the coating material is anticorrosion material.

13 . The coating device according to claim 5 , wherein the coating material is anticorrosion material.

14 . The coating device according to claim 6 , wherein the coating material is anticorrosion material.

15 . The coating device according to claim 7 , wherein the coating material is anticorrosion material.

16 . The coating device according to claim 8 , wherein the coating material is anticorrosion material.

17 . A method for coating an exposed conductor of an electrical wire with coating material, the method comprising:
arranging a plurality of electrical wires; applying a jetting outlet arranged spaced apart from the electrical wire and the conductor, and electrifying the jetting outlet and the conductor; while jetting the liquid including the coating material out of the jetting outlet, relatively-moving the jetting outlet and the plurality of electrical wires along an arrangement direction of the plurality of electrical wires.
