Abstract

A method for manufacturing a terminal with an electric wire includes: forming a conductor exposed portion by removing a resin coating of an electric wire; forming a wire-terminal connection portion by connecting a terminal fitting to a position of the conductor exposed portion; and supplying a sealing material from a nozzle to the wire-terminal connection portion. During supply of the sealing material, the nozzle is moved in X-, Y- and Z-directions or a relative position between the wire-terminal connection portion and the nozzle is changed in the X-, Y- and Z-directions.

Claims

1. A method for manufacturing a terminal with an electric wire comprising:

forming a conductor exposed portion by removing a resin coating of an electric wire;

forming a wire-terminal connection portion by connecting a terminal fitting to a position of the conductor exposed portion; and

supplying a sealing material from a nozzle to the wire-terminal connection portion,

wherein during supply of the sealing material, the nozzle is moved in X-, Y- and Z-directions or a relative position between the wire-terminal connection portion and the nozzle is changed in the X-, Y- and Z-directions.

2. The method for manufacturing a terminal with an electric wire according to claim 1,

wherein the wire-terminal connection portion is formed in a range comprising:

a conductor crimping part in which the conductor exposed portion is crimped by a conductor crimping piece of the terminal fitting;

a non-crimping part around the conductor crimping part; and

a coating crimping part in which the resin coating in a vicinity of the conductor exposed portion is crimped by a coating crimping piece of the terminal fitting, and

wherein the sealing material is supplied to cover the wire-terminal connection portion formed in the range, and during supply of the sealing material, at least in a position of the non-caulking part, the nozzle is moved in the X-, Y- and Z-directions or the relative position between the wire-terminal connection portion and the nozzle is changed in the X-, Y- and Z-directions.

3. The method for manufacturing a terminal with an electric wire according to claim 1, further comprising:

prior to supply of the sealing material, determining an initial position of the nozzle based on an image of the wire-terminal connection portion which is captured from a predetermined position by a camera.
