Wire protection film stripping device and wire protection film stripping device method

Abstract

The invention discloses a wire protection film stripping device and a wire protection film stripping device method which can strip a protection film which covers the wire circumferentially, easily and reliably. The wire protection film stripping device comprises a wire supporting unit used for supporting the wire, a pair of cutting members facing each other across the wire, cut applying units which enables the pair of cutting members to abut on the protection film formed on the outer surface of the wire from the two sides of the wire and apply cuts to the protection film, a cutting member relative motion unit which enables the pair of cutting members applying the cuts to the protection film to move relatively along the length direction of the wire, and a cutting member rotation unit which enables the pair of cutting members facing each other across the wire to rotate with the wire serving as the rotation center. The cutting member rotation unit comprises a rotation member allowing the wire to pass through and being capable of rotating with the wire ass the rotation center. The pair of cutting members are arranged on the rotation member.

Description

technical field [0001] The present invention relates to a protective film peeling device and a protective film peeling method for peeling a protective film formed on an outer surface of a wire rod. Background technique [0002] Conventionally, when a wire covered with a protective film such as an insulating protective film is used for winding, the protective film of the wire needs to be partially peeled off in order to ensure electrical contact with the terminal on which the wire is wound or to directly serve as an electrical contact. In addition, as an apparatus for peeling off the insulating protective film of a flat wire having a rectangular cross-sectional shape, there is known an apparatus that brings a rotating roller or a friction member into contact with the insulating protective film to peel off the insulating protective film. In the case of such a device, the insulating protective film is peeled off by moving the roller, the friction member, or the wire, but there ...

AI Technical Summary

Problems solved by technology

Even if the protective film on the side remains, if the protective film on the opposite main surface of the wire is peeled off, the electrical contact between the wire and the terminal can be ensured, but the above-mentioned protective film peeling device cannot be used to remove the protective film formed on the entire circumference of the wire. The protective film of the wire rod is peeled off, and there remains a problem to be solved that the protective film formed on the entire circumference of the wire is required to be peeled off, but this requirement cannot be met.
