Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for processing a covered lead wire as a preparatory step for attaching the covered lead wire to a terminal or the like.

Conventional soft ultra-fine coated lead wire (hereinafter referred to as coated lead wire)
It is difficult to automate the coating removal process, and most of the time it relies on manual work.

The work requires skill and concentration, and there are problems that can lead to wire breakage, such as core wire breakage and variations in the length of peeling of the coating.

In the present invention, by making a notch of a certain depth in the coating of the coated lead wire and attaching the tip of a diamond file to the tip of the coating stripping chuck, the coating can be grasped with low pressure and diamond grains are scattered. By doing this, the wire can be gripped securely, and the core wire can be twisted to increase the strength of the core wire, thereby eliminating wire breakage, which is the biggest problem with peeling off the wire, and automating the process. .

An embodiment of the present invention will be described based on the drawings.

First, FIG. 2 shows an outline of the coated lead wire processing apparatus of the present invention, where A is a wire supply section, B is a wire drawing ridge section,
C is a line length adjustment part, D is a cutter part, E is an index part, and F and F' are chuck parts.

Next, the covered lead wire processing apparatus will be specifically explained.

Tension is applied to the single coated lead wire 1 wound around the bobbin 4 by a roller 5 and a tension roller 6, and a strainer 7
The curls are removed using felt 8.

The coated lead wire 1 from which curls have been removed in this way protrudes from the wire drawing outlet 9, and the wire drawing chuck holder 11 pulls the slide shaft 12 in the direction of the arrow d. , and pull out the covered lead wire 1 for a certain length.

The wire length adjustment pin 13 moves to the position 13' to vary the length of the covered lead wire 1.

A single air chuck 15 attached to the index chuck holder 14 is expanded in the vertical direction by a cam, and the air chuck 15 grips the coated lead wire 1.

Next, the cutter iD and chucks il F and F' are used in the same process, but as shown in FIG. Cutting C is performed using the notch a1 cutting cutter 19, and the process is performed as shown in FIG.

On the other hand, the torsion wire chuck holder 21 moves in the e direction along the slide shaft 12, and grips the coating 17 of the coated lead wire 1 with the diamond tip 3 at the tip of the torsion wire chuck 2.

The rotation of the motor 23 is transmitted to the torsion wire chuck 2, and the cam moves the torsion wire chuck holder 21 on the slide shaft 12 in the f direction, and the torsion wire chuck 2 moves while rotating, thereby removing the end of the covered lead wire 1. The coating 17 is peeled off and the core wire 20 is twisted as shown in FIG.

At this time, in the lower part of the device, peeling on the opposite side and twisting of the core wire 20 are performed at the chuck portion F'.

Furthermore, by adding the function of attaching the covered lead wire 1 to the terminal in part 0, it is possible to attach the covered lead wire to the terminal using the apparatus of the present invention.

As described above, the coated lead wire processing device of the present invention can peel off the coating on both ends of a soft, ultra-fine coated lead wire after cutting it to a fixed size without breaking the wire, and can also twist the core wire. Since the chip is mounted using a single twisted wire chuck, the chuck pressure on the coating can be reduced, reducing the risk of wire breakage, and all work is automated, greatly improving productivity. It has its advantages and is a dog of industrial value.
