BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic wiring machine for temporarily assembling a large number of electric wires on a wiring table, mainly for manufacturing a wire harness.

[0002]

2. Description of the Related Art An automatic wiring machine is a machine for temporarily assembling a large number of electric wires to be assembled into an electric device such as a switchboard in order to form a wire harness. As shown, a wiring table 2 on which a large number of coordinate pins 1 are erected, and a traveling frame 3 that can move in the horizontal vertical direction (X direction) on the wiring table 2 while straddling the wiring table 2. , Along the traveling frame 3 in the horizontal direction (Y
Direction), and a controller 5 for controlling the movement and operation of the traveling frame 3 and the wiring head 4.

The wiring head 4 is controlled by the controller 5 and moves laterally in association with the vertical movement of the traveling frame 3 to move to an arbitrary position on the wiring table 2. Outside the machine, from the electric wire supply section 6 to the electric wire exchange section 7
The electric wire is adapted to be supplied via.

[0004]

By the way, the above-mentioned automatic wire laying machine is one in which a long electric wire is successively cut into a predetermined length and laid on the wire laying table 2. The terminal of each wire that has been wired remains disconnected and is not processed.

For this reason, conventionally, an operator removes the electric wires after the wiring from the wiring table 2, peels off the coating of each electric wire, and carries out a terminal treatment work such as attaching a crimp terminal, which requires a lot of manpower. Not only that, it took time to manufacture, and the work efficiency could not be improved easily.

On the other hand, in addition to the automatic wire laying machine, there is already a dedicated device for the end treatment of electric wires, which automatically carries out the work such as cutting the electric wire, stripping the covering, and attaching the crimp terminal. Therefore, it is considered to install such a terminal processing device in an automatic wiring machine. That is, the terminal treatment device as described above is installed in the preceding stage of the automatic wiring machine, and the electric wire subjected to the terminal treatment from the terminal treatment device is supplied to the wiring head 4 of the automatic wiring machine so that the electric wire after the terminal treatment is performed. Wiring is performed on the wiring table 2. By doing so, the wiring and the end treatment of the electric wire are automated, and the work can be labor-saving and efficient.

[0007] However, if the electric wire subjected to the terminal treatment is sent to the wiring head of the conventional automatic wiring machine, the following problems occur.

As shown in FIG. 3, inside the wiring head 4 of a conventional automatic wiring machine, in addition to the printer 8 for display printing and the cutting blade 9, a pair of feed rollers 10 and straightening rollers are provided. There are rollers such as 11 and the electric wire W passes between these rollers 10 and 11. However, when an electric wire with a crimp terminal is passed through here, the crimp terminal is broken or the wiring head 4 side has a mechanism. Damage occurs. Therefore, in the conventional automatic wiring machine, it is practically impossible to supply the terminated electric wire to the wiring head 4 to perform wiring.

The present invention addresses the above-mentioned problems of the prior art, in which a terminal-treated electric wire is laid on a wiring table without any trouble so as to be terminal-treated like a wire harness. It is an object to save labor and improve the efficiency of the manufacturing process of the temporary assembly of the electric wire.

[0010]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a wiring table, a wiring head movable vertically and horizontally in a horizontal plane with respect to the wiring table, and a wiring table. A terminal processing device that is installed adjacent to the terminal and sends out the processed electric wire to the wiring table side, and a relay that holds the end of the terminal processed electric wire from this terminal processing device and transfers it to the wiring head side that stands by at a predetermined position. The automatic wiring machine is provided with a winding reel for winding the terminal treated electric wire from the relay means and unwinding the electric wire to be fed onto the wiring table.

[0011]

In the automatic wire laying machine having the above-mentioned structure, while the wire laying head is standing by at a predetermined position near the terminal processing device, the electric wire terminated by the terminal processing device is wound by the relaying means around the wire laying head. It is delivered to a take-up reel and wound on the reel. Then, in association with the movement of the wiring head on the wiring table, the take-up reel reversely rotates and rewinds the electric wire, so that the terminal-treated electric wire is laid on the wiring table.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to an embodiment shown in FIG. FIG. 1 is a perspective view of an automatic wiring machine according to an embodiment of the present invention.

The automatic wire laying machine according to this embodiment comprises a wire laying machine main body 20 substantially corresponding to the above-mentioned conventional automatic wire laying machine, an electric wire end treatment device 30, and a relay means 40.

The main body 20 of the wire laying machine is a wire laying table 2 on which a large number of coordinate pins 1 are erected, and is moved over the wire laying table 2 in the horizontal vertical direction (X direction). It includes a traveling frame 3, a wiring head 4A that can move in the horizontal lateral direction (Y direction) along the traveling frame 3, and a controller 5A.

Like the wiring head 4 of the conventional automatic wiring machine, the wiring head 4A here moves laterally in association with the vertical movement of the traveling frame 3 under the control of the controller 5A. Although it moves to an arbitrary position on the line table 2, unlike the conventional one, it does not have a cutting blade, a feed roller, a straightening roller, etc., and instead drives a motor (not shown). Thus, the take-up reel 21 that is rotated in the normal and reverse directions is provided in a lateral direction, and at least the upper surface portion is exposed. Further, the controller 5A controls the movement and operation of the traveling frame 3 and the wiring head 4A, and also controls the operation of the terminal processing device 30 and the relay means 40.

The terminal processing device 30 has a base 31 on which
The electric wire take-in unit 32 also serving as the electric wire cutting unit, the printer 3
3, marking tube inserter 34, sleeve inserter 3
5. The strip processing section 36 and the crimp terminal mounting section 37 are arranged in this order. The electric wire W supplied to the electric wire intake section 32 is cut into a required length, and the terminal is sequentially processed as required. It is designed to be fed out from the crimp terminal mounting portion 37, and is installed at a position adjacent to one longitudinal end of the wiring table 2 so that the feeding end approaches the moving area of the wiring head 4A.

The relay means 40 is, for example, a multi-axis robot having a chuck 41 at its tip and is installed between the wiring table 2 and the terminal processing device 30. When the wiring head 4A is at a predetermined position close to the terminal processing device 30, the relay means 40 grabs the tip of the electric wire at the sending end of the terminal processing device 30 and attaches this to the take-up reel 21 of the wiring head 4A. It is something to pass.

It should be noted that the take-up reel 21 has a locking portion (for example, a processing terminal insertion hole) for locking the processing end of the electric wire so that the processing end of the electric wire can be pulled out freely. By locking the processing terminal of
The electric wire can be wound up. Also, the wiring head 4
It is desirable that a guide for guiding the electric wire downward is provided on the lower surface of the main body of A. Then, the rewinding electric wire is sent downward from a predetermined position in the width direction of the wiring head 4A by the guide.

Next, the operation of the above configuration will be described. Before starting the wiring, no electric wire is supplied to the wiring head 4A and no electric wire is present on the take-up reel 21. Then, the wiring head 4A first moves laterally in association with the vertical movement of the traveling frame 3 to move to a position close to the wire feeding end of the terminal processing device 30, and stands by at that position.

On the other hand, the terminal processing device 30 cuts the electric wire W supplied thereto into a predetermined length, performs terminal processing on the front end and the rear end thereof, and sends it out from the crimp terminal mounting portion 37. In connection with the electric wire feeding from the terminal processing device 30, the relay means 40 starts its operation, grasps the tip of the electric wire subjected to the terminal treatment, carries this to the take-up reel 21 side, and the engaging portion of the reel 21. To be locked.

With this, the take-up reel 21 can take up the electric wire, and by normally rotating, the end-treated electric wire of a predetermined length is taken up. When the winding of the electric wire by the take-up reel 21 is completed, the wiring head 4A horizontally moves in association with the vertical movement of the traveling frame 3 and moves to the wiring start position. Then, the take-up reel 21 is reversely rotated at that position, and the movement is started again. As a result, the terminal-treated electric wire wound on the take-up reel 21 is rewound, sent out from the rear end of the winding onto the wiring table 2, and laid on the table 2.

[0022]

As described above, according to the present invention, the terminal treatment of the electric wire and the wiring are automatically performed. Therefore, a temporary assembly of the terminal-treated electric wire such as a wire harness is
It can be efficiently manufactured without requiring manpower.

In addition, the terminal-treated electric wire is laid through the winding and unwinding operations of the take-up reel, and during that time, an unreasonable force such as pressing of the roller is not applied to the laying head. It is possible to manufacture a highly reliable product without breaking the terminals, and since the mechanism of the wiring head is not damaged, it is possible to manufacture without trouble.
