Claims (5)

An electric wire cutting device that pulls out an electric wire from the electric wire supply reel and cuts it to a predetermined length;
An electric wire processing apparatus for performing predetermined processing on the cut electric wire;
An inspection device that detects the presence or absence of processing defects by imaging the processing portion of the electric wire;
The station in which the wire cutting device is disposed, the station in which the wire processing device is disposed, and the station in which the inspection device is disposed are sequentially moved to receive and / or deliver the wire at each station. An apparatus for manufacturing an electric wire processed product comprising an electric wire conveying device.   The electric wire transfer device includes a guide member arranged along the arrangement of the stations, a slide base that reciprocates on the guide member, and at least two electric wire clamps installed on the slide base. The said electric wire clamp is a manufacturing apparatus of the electric wire processed goods of Claim 1 which can receive and deliver an electric wire in at least two adjacent stations.   The inspection apparatus includes a plurality of cameras that capture the processed portion of the electric wire from a plurality of directions, detects a defective portion based on an image captured by the camera, and an electric wire that does not have a defective portion and a defective The apparatus for manufacturing an electric wire processed product according to claim 1 or 2, wherein the electric wire having a portion is sorted and discharged.   The electric wire includes a core wire, a dielectric layer made of an insulating coating covering the outer periphery of the core wire, a shield layer made of a braided wire covering the outer periphery of the dielectric layer, and an insulating coating covering the outer periphery of the shield layer A coaxial cable composed of a protective layer, and the electric wire processing apparatus strips the protective layer, the shield layer, and the dielectric layer of the coaxial cable by changing their lengths, and the portion where the shield layer is exposed. The apparatus for manufacturing a wire processed product according to any one of claims 1 to 3, wherein the device forms a portion where the dielectric layer is exposed and a portion where the core wire is exposed.   The detection of the defective portion in the inspection apparatus is performed by checking whether the thickness of the exposed portion of the shield layer is equal to or smaller than a predetermined value, and whether the thickness of the exposed portion of the dielectric layer is equal to or smaller than a predetermined value. Determining whether the color tone or brightness of the exposed portion of the dielectric layer is different from the original color tone or brightness of the dielectric layer, and whether the thickness of the exposed portion of the core wire is equal to or less than a predetermined value. The manufacturing apparatus of the electric wire processed product of Claim 4 made by doing.
