Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an apparatus for manufacturing an intermittently exposed conductor wire, and particularly detects non-insulation by a spark generated by applying power from the front and back of a tape-shaped intermittently exposed conductor wire. The present invention relates to an apparatus for manufacturing an intermittently exposed conductor wire having an insulation test section.

[Problems to be solved by conventional technology and invention] Conventionally, when a tape-like electric wire is used for connection between electronic devices, a conductor of the tape-like electric wire is exposed without connecting a connector plug to a terminal thereof, and reinforced on one side. The method of attaching a material and inserting it directly into a socket has been adopted. In order to manufacture such an end-treated tape-shaped electric wire, as shown in FIG. 4, a window-mounted insulating tape 3 having windows 2 provided at desired intervals and a windowless insulating tape 3 having no windows 2 are provided. A continuous intermittently exposed conductor wire 6 having a conductor exposed portion 4 and an insulating portion 5 is formed by sandwiching the conductor 1 from the front and back. Thereafter, a reinforcing material 7 is adhered to the windowless insulating tape 3 at a position corresponding to the window 2 to reinforce the exposed conductor 1 and to form both end lines a of the window 2.
-A ', and then the center line b-
b 'and cut the individual terminal conductors 1 as shown in FIG.
Is obtained to expose the terminal-treated electric wire 8.

On the other hand, in a normal insulation test during the manufacture of such an electric wire having no intermittent exposed portion, for example, a non-insulated portion is allowed to pass through a stylus impressed to several tens of volts, and a spark is generated. Or by inserting an ammeter and reading the deflection of the needle to perform an insulation test. However, the insulation test during the production of the above-described terminal-treated electric wire cannot be performed because the conductor exposed portion is provided intermittently, and the insulation test can be performed only in a unit test in an individual product state. . For this reason, there was a drawback that the test could not be performed continuously and the efficiency was very poor.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a manufacturing apparatus for an intermittently exposed conductor wire having an insulation test section capable of continuously performing an insulation test on the intermittently exposed conductor wire.

[Means for Solving the Problems] In order to achieve this object, an apparatus for manufacturing an intermittently exposed conductor wire according to the present invention includes a conductor supplier for supplying a plurality of conductors in parallel, and an insulator for clamping the conductors. An insulator supply body that supplies a, a window opening device that provides a rectangular window that forms a conductor exposed portion in the insulator, and a heating roll that integrates the conductor and the insulator to form an intermittently exposed conductor wire. A manufacturing apparatus for an intermittent exposed conductor wire, comprising a winding machine for the intermittent exposed conductor wire, wherein the intermittently exposed conductor wire is disposed above and below the intermittently exposed conductor wire between the heating roll and the winding machine. An electrode in which an electrode contactor is implanted toward the intermittently exposed conductor wire, and a sensor for detecting a start end and an end of the conductor exposed portion of the intermittently exposed conductor wire, and the sensor detects the start end. Then to the intermittently exposed conductor wire And an insulation test section for supplying current to the intermittently exposed conductor wire when the sensor detects the termination.

[Operation] In order to continuously perform an insulation test on a tape-shaped electric wire having a conductor exposed intermittently, a conductor-exposed portion is detected by a light emitting / receiving sensor or the like provided on the front and back of the tape-shaped electric wire. A brush-like contact placed on the power-applying electrode is applied to apply electricity, and at the exposed conductor, the contact is moved mechanically to release the contact or to stop applying electricity. To perform an insulation test. In this manner, the insulation test can be performed continuously during the manufacture of the intermittently exposed conductor wire before cutting into the single terminal-treated wire.

[Embodiment] An embodiment to which the manufacturing apparatus for intermittently exposed conductor wires of the present invention is applied will be described below with reference to the drawings.

As shown in FIG. 1, an apparatus for manufacturing an intermittently exposed conductor wire includes a conductor supply unit for supplying a conductor 1 upstream of a production line.
11 and insulating tape supply units 31 and 32 which are insulation supply units for supplying insulation tapes 31-1 and 32-1 which are heat-fusible insulations sandwiching the supplied conductor 1. ing. In the vicinity of the insulating tape supply body 31, there is provided a window opening device 9 for forming the window 2 shown in FIG. 4 in the insulating tape 31-1 supplied therefrom. Insulating tape 31-1 with window on which window 2 is formed and insulating tape 32 without window without window 2
A heating roll 10 is provided at the joint between the insulating tape and the conductor so as to heat the conductor 1 so as to be heat-fused together with the conductor 1 held therebetween. Since the window 2 is opened, the reinforcing member supply body 71 that supplies the reinforcing member 7 (FIG. 5) for reinforcing the conductor exposed portion 4 of the intermittently exposed conductor wire formed to have the conductor exposed portion 4 and the insulating portion 5 is provided. The heating roll 10 is provided downstream of the production line. The reinforcing material 7 from the reinforcing material supply body 71 is supplied to the back side of the conductor exposed portion 4 as shown in the figure, and the reinforcing material 7 is cut by the cutter 72 to the width of the intermittently exposed conductor wire and guided to the heating roll 12. It is supposed to be. The heating roll 12 is provided with an insulation test section 13 so as to continuously perform an insulation test on the intermittently exposed conductor wire as described later.

The cutter 14 is provided on both sides of the window 2 as shown in FIG.
It has a function of cutting along the line a ', and the winding machine 15 is for winding the product which has been subjected to the insulation test.

As shown in FIG. 2, the insulation test sections 13 are arranged to face each other, and each of the one and the other electrodes on which a brush-like touch element 17 is implanted.

A detection signal based on the detection signal from the exposed portion detecting means 50 connected to the exposed portion detecting means 50,
In the case of detection information, the air cylinder 22 is actuated to bring the tentacles 17, 17 into contact with the front and back of the intermittently exposed conductor wire 6, and in the case of "end" detection information, the air cylinder 22 is returned to the initial state and the tentacle 17 is intermittently exposed conductor wire. 6 and a control means CPU constituted by a microcomputer or the like having a function of making it non-contact.

In such an insulation test section 13, the photoelectric sensor 19 detects the end 21 of the conductor exposed portion 4 of the intermittently exposed conductor wire 6 by the transmitted light from the photoelectric lamp 18, and sends a detection signal to the control means CPU. The control means CPU outputs this detection signal to the drive mechanism 22, and moves the electrode 16 so that the stylus 17 contacts the surface of the insulating tapes 31-1, 32-1. The electrode 16 is always energized, and is charged with a voltage that causes sparking if the insulating portion 5 has a crack or the like. The spark can be confirmed visually or by an ammeter (not shown). Then, the intermittently exposed conductor electrode 6 is moved, the photoelectric sensor 19 detects the start end 20 of the conductor exposed portion 4, and when the detection signal is sent to the control means CPU, the control means CPU
Actuates the drive mechanism 22 to separate the tentacle 17 from the intermittently exposed conductor wire 6 and to move it from the tentacle 17 to a distance at which spark does not occur. By doing so, the insulation test can be performed while continuously moving the intermittently exposed conductor wire.

As another insulation test apparatus, as shown in FIG.
When the photoelectric sensor 19 detects the start end 20 of the conductor exposed portion 4 of the intermittently exposed conductor wire 6 by receiving light from the photoelectric lamp 18, the photoelectric sensor 19 sends a detection signal to the control means CPU, and outputs the detection signal to the control means CPU. A switch 23 for stopping power application to the electrode 16 by a signal may be provided. The switch 23 is turned on by a signal sent to the control means CPU when the photoelectric sensor 19 detects the end 21 of the conductor exposed portion 4. The energization is turned on in the insulating portion of the electrode 16 and the energization is turned off in the exposed portion of the conductor, so that the probe 17 can be installed at a fixed position and the insulation test can be continuously performed.

The above-described example is an embodiment of the present invention, and the present invention is not limited to this. The sensor for detecting the conductor exposed portion may be another known sensor. The driving mechanism for moving is not limited to the air cylinder, and any type can be adopted as long as the contact is electrically or mechanically avoided from the exposed conductor.
