[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harness manufacturing apparatus for manufacturing a harness formed by press-connecting a plurality of electric wires to a connector.

[0002]

2. Description of the Related Art A plurality of electric wires arranged side by side in a plane are continuously supplied, and the plurality of electric wires are pressed into contact with a connector and cut to a predetermined length, whereby the connectors are attached to the plurality of electric wires. 2. Description of the Related Art A harness manufacturing apparatus that manufactures a manufactured harness is conventionally known. This harness manufacturing equipment includes
For example, there are ones that manufacture a harness (feed-through type harness) in which a connector is connected by pressure welding not only to both ends of an electric wire, but also those that manufacture a harness in which a connector is connected by pressure connection only to both ends of an electric wire. is there.

An example of a harness manufacturing apparatus for manufacturing a feed-through type harness is disclosed in JP-A-60-1175.
There is a type described in Japanese Patent Publication No. 80. This harness manufacturing apparatus includes a press-contact portion for press-connecting a plurality of wires supplied from a wire supply portion to a connector, a clamp for holding the connector to which the wires are press-connected at the press-contact portion, and reciprocating the clamp. An electric wire measuring section is provided at a position opposite to the electric wire supply section across the press-contact section for measuring the electric wire length, and a clamp holding the connector holds the electric wire measuring section at a predetermined position. By reciprocating by a distance, electric wires are pressed and connected to the connector at predetermined intervals to manufacture a harness.

On the other hand, as an example of a harness manufacturing apparatus for manufacturing a harness in which a connector is press-connected to both ends of an electric wire of a predetermined length, two press-contact portions, an electric wire supplied to the press-contact portion and an electric wire supplied thereto There is known a roller provided with a roller for measuring the length of the paper (Japanese Patent Laid-Open No. 61-18 / 1986).
No. 881). In this harness manufacturing apparatus, after the leading end of the wire is pressure-connected to the connector at one press-contact portion, the wire is sent out while being measured by a roller, and the rear end of the wire is pressed against the connector at the other press-contact portion. Connected, thereby producing the harness. By the way, since the connection between the electric wire and the connector of the manufactured harness is not always good, this harness manufacturing device inserts a check pin into the connector of the manufactured harness to connect the electric wire and the connector. A device for automatic inspection is added.

[0005]

The harness manufacturing apparatus for manufacturing the above-mentioned feed-through type harness has a configuration in which a clamp holding a connector is moved along a wire measuring section in order to measure a wire. Therefore, a length measuring unit having a length corresponding to the moving distance is required. For this reason, for example, if the electric wire length of the harness is 2 m, the length of the length measuring section is also required about 2 m, and even if the clamp is reciprocated twice and the length is measured, about 1 m is required.
A harness manufacturing apparatus having such a long measuring section has a problem that the entire apparatus cannot be made compact and cannot be made compact, and the occupied area becomes large.

In view of the above circumstances, it is a first object of the present invention to provide a compact harness manufacturing apparatus capable of manufacturing a feed-through type harness. On the other hand, in the above-mentioned harness manufacturing apparatus for manufacturing a harness in which connectors are connected by pressure contact only to both ends of an electric wire, two press-contact portions are required, and therefore the entire apparatus becomes complicated and large. In this harness manufacturing apparatus, since the electric wire is cut at the same time when the connector is pressure-connected to the rear end of the electric wire, there is also an inconvenience that a feed-through type harness cannot be manufactured.

The apparatus for inspecting the connection between the electric wire and the connector in the above-mentioned harness manufacturing apparatus is configured to inspect the harness after the end of manufacture by moving the place. When applied to the inspection of a through type harness, for example, even if only one connector connected to the middle part of the wire has a connection failure, the entire completed harness becomes defective,
For this reason, there is a problem that the wire and the connector, which are press-connected after the intermediate portion, are wasted.

In view of this problem, it is a second object of the present invention to provide a harness manufacturing apparatus having a function of inspecting the connection between an electric wire and a connector during manufacture of the harness.

Thereafter, a plurality of wires continuously supplied from the wire supply unit are measured by the roller, and the plurality of wires are gripped by a wire clamp as needed, and a middle portion of the plurality of wires is pressed by a pressure contact portion. It is press-connected to the second connector. Further, when the connector is press-connected to another portion in the middle of the plurality of wires, the length of the wire is further measured with a roller. Is press-connected to the connector. When the connector is connected to the part corresponding to the end of the wire when completed as a harness, the wire is cut with a cutting blade and the end of this wire is corrected to correct the difference in the arrangement position between this cutting blade and the press-contact part The wire is gripped and pulled by the wire clamp so that the portion moves to the press-contact portion, and the terminal portion of the wire is press-connected to the last connector at the press-contact portion. As described above, in the first harness manufacturing apparatus of the present invention, since the roller for measuring the length is arranged between the electric wire supply part and the press contact part and the length of the electric wire is measured by this roller, the apparatus is compact. A feed-through type harness is manufactured by the device.

In the first harness manufacturing apparatus,
Instead of press-connecting the middle portion of the wire to the connector, it is also possible to press-connect only the ends of the wire to the connector. For this purpose, after the tip is press-connected to the connector, the length of the wire is measured with a roller, and when the wire reaches a predetermined length, the wire is cut with a cutting blade, and the end of the wire is pressed into contact with the connector. It is preferable that the electric wire is gripped and pulled by the electric wire clamp so as to move to the end, and the terminal end of this electric wire is press-connected to the last connector at the press-contact portion.

Further, when a plurality of rollers for independently measuring the lengths of a plurality of electric wires are provided, a harness having a plurality of electric wires having different lengths can be manufactured. For this purpose, for example, each roller measures the length of each of a plurality of electric wires, and when each of them reaches a predetermined length, cuts the plurality of electric wires with a cutting blade. It is preferable to hold and pull the electric wire by the electric wire clamp so as to move, and to press-connect the last connector to the terminal end of the electric wire at the press-contact portion.

Further, in the second harness manufacturing apparatus of the present invention having the function of checking the connection between the electric wire and the connector during the manufacturing of the harness, the second check pin provided on the connector clamp is connected to the connector clamp. The first check pin provided on the press-contact portion contacts the contact of the connector press-connected by the press-contact portion, and the first check pin and the second check pin in the continuity check portion contact the contact of the pinched connector. Is inspected, so that the quality of the connection between the electric wire and the cocota can be inspected even during the production of the harness. As a result, when a conduction defect is found, the subsequent connection between the electric wire and the connector can be stopped, and the waste of the electric wire and the connector can be reduced.

The two cutting blades 26, the electric wire clamp 36, the stuffer 48 of the press-contact portion 28 (see FIG. 1), the connector guide 32, and the connector clamp 40 are open. As shown in FIG.
When the electric wire is fed so that the tip of the electric wire 12 reaches the press-contact portion, the connector guide 32 rises one step and guides the electric wire 12. Next, as shown in FIG.
As a result, the distal end of the electric wire 12 is press-connected to the connector 50. When the pressure welding step is completed, a part of the electric wire 12 is gripped by the electric wire clamp 36 as shown in FIG. 6, the connector guide 32 and the stuffer 48 are separated, and the preparation for the connector clamp 40 to grip the connector 50 is completed. . Next, as shown in FIG. 7, the connector 50 is gripped by the connector clamp 40, and the second check pins 42 provided on the connector clamp 40 come into contact with the contacts (not shown) of the connector 50. The connector guide 32 includes the following connector as the parts feeder 30.
(See FIG. 2). Next, as shown in FIG. 8, the electric wire clamp 36 is opened, the connector clamp 40 is moved to a predetermined position, and the electric wire 12 is moved to the roller 18 (see FIG. 1).
The length of the electric wire 12 is measured while being pulled out from the electric wire supply unit. Next, as shown in FIG. 9, the electric wire clamp 36 is closed, the electric wire 12 is moved to a right side in the figure by a predetermined distance, and the electric wire 12 is further pulled out from the electric wire supply unit. afterwards,
As shown in FIG. 10, a new connector is press-fitted to the middle portion of the electric wire 12, and after the stuffer 48 has risen, the continuity check section checks the continuity between the first check pin 34 and the second check pin 42. Is done. Here, when a conduction failure is found, the cutting blade 26 after the process shown in FIG.
As a result, the electric wire is cut, and the connector and the electric wire connected to the connector are determined to be defective and are discarded. Then, FIG.

Next, as shown in FIG. 16, the terminal end of the electric wire 12 is press-connected to the connector, and then a continuity test is performed in the same manner as in the step shown in FIG. The manufactured harness is discharged by the connector discharge cylinders 38a and 38b (see FIG. 2), returns to the process shown in FIG. 3, and shifts to manufacturing of the next harness.

As described above, in the harness manufacturing apparatus of this embodiment, the operation of the cutting blade and the operation of the press contact portion are independent of each other, and a feed-through type harness is manufactured. In addition, since the wire clamp moves beyond the press-contact portion 28 and the length of the wire is measured by a roller arranged on the upstream side of the press-contact portion 28, the wire is connected to, for example, FIG.
As shown in FIG. 6, even when the electric wire is hung down, the electric wire can be press-connected to the connector, so that the entire apparatus is compact. Also, when a feed-through type harness is manufactured using this device, conduction is inspected each time an electric wire is pressed into a connector. Connection is stopped and the process returns to the first step, so that waste of wires and connectors is reduced.

The harness manufacturing apparatus shown in the above embodiment can be used not only for manufacturing a feed-through type harness, but has general versatility. Hereinafter, this point will be described. With reference to FIGS. 17 to 28, a description will be given of a manufacturing process of a harness in which a connector is pressed and connected only to both ends of a predetermined-length electric wire using the above-described harness manufacturing apparatus.

Here, since only the leading end and the trailing end of the electric wire are press-connected to the connector, many steps are the same as the steps of manufacturing the feed-through type harness shown in FIGS. 3 to 16, and the same steps will be described. Omitted. That is, FIG.
23 to FIG. 23 are the same as the steps shown in FIG. 3 to FIG. 24 and FIG. 25 correspond to FIG. 12 and FIG.
3 is the same as the step shown in FIG.

In the step shown in FIG. 26, the connector clamp 40 is moved to a predetermined position after the distal end of the electric wire 12 is press-connected to the connector, and after the electric wire 12 has been measured for a predetermined length, the cutting blade 26 is used. Is a step of cutting. Thereafter, as shown in FIG. 27, the cutting blade 26 is opened, and the wire clamp 36 moves so that the terminal end of the wire 12 moves to the position of the connector guide 32. Next, as shown in FIG. 28, the terminal end of the electric wire 12 is press-contacted to the connector, a continuity test is performed in the same manner as in the step shown in FIG. 10, and the harness manufacturing step is completed.

As described above, the harness manufacturing apparatus of the present embodiment can also manufacture a harness in which connectors are connected by pressure contact only to both ends of an electric wire. Next, FIG. 29 to FIG.
With reference to FIG. 5, a description will be given of a process in which a connector is pressure-welded to the ends of electric wires having different lengths using the above-described harness manufacturing apparatus. FIG. 29 is the same view as FIG. 3 and shows a start state of the harness manufacturing, in which the tip of the electric wire 12 is at a position in the middle of the guide pipe 24, and the upper and lower two cutting blades 26,
The electric wire clamp 36, the stuffer 48 of the press contact portion 28, the connector guide 32, and the connector clamp 40 are open. In this embodiment, one roller 18 (see FIG. 1) is arranged for each electric wire (only three are shown in FIG. 30), and the length of each electric wire is measured by an encoder 19 (see FIG. 2). Therefore, as shown in FIG.
Each electric wire can be sent out such that each electric wire has a different length. After each electric wire is sent out in this manner, the electric wire clamp 36 is closed as shown in FIG. next,
As shown in FIG. 32, after the wire 12 of a predetermined length is pulled out from the wire supply unit and the wire clamp 36 moves to the position shown in the drawing, the connector guide 32 is raised one step to
Guide. Next, as shown in FIG.
Thereby, the electric wire 12 is cut. Thereafter, as shown in FIG. 34, the cutting blade 26 is opened, and the wire clamp 36 moves so that the terminal end of the wire 12 moves to the position of the connector guide 32. Then, as shown in FIG.
The terminal portion of the electric wire 12 is press-connected to the connector, and the harness manufacturing process ends.

As described above, in the harness manufacturing apparatus of the present embodiment, one roller 18 (see FIG. 1) is arranged for each electric wire (only three are shown in FIG. 30), and an encoder 19 (see FIG. 2). ), The length of each electric wire is measured, so that a harness having electric wires having different lengths from each other can be manufactured. Next, the schematic structure of the continuity inspection unit will be described with reference to FIG. The continuity inspection unit 60 is provided with a power supply 64 for providing a potential difference between the first check pin 34 and the second check pin 42 through an electric wire 62 and a potential difference therebetween, for example, a light bulb 70. When conduction between the two connectors 66 and 68 is good, the light bulb 7
0 is lit, but when conduction is poor, the bulb 70 is not lit, so that the quality of conduction can be determined. still,
Needless to say, the conduction and non-conduction can be automatically determined using a microprocessor or the like. Further, if an electric resistance measuring unit is arranged in place of the light bulb 70 and a harness exceeding a predetermined resistance value is identified as defective, it is possible to detect a harness that has continuity but incomplete pressure contact connection.

A check circuit having the following configuration may be added between the stuffer 48 and the second check pin 42. That is, by interposing an insulator such as a plastic plate between the stuffer 48 and the ram supporting the stuffer 48, the stuffer 48 is insulated from the ram and the press body. The stuffer 48 and the second check pin 42 are connected via a check circuit.

Usually, the stuffer 48 is designed so as not to contact the press-contact portion of the press-contact when the press-contact is normally accommodated in the connector. However, the conventional harness manufacturing apparatus cannot detect deformation of the press contact portion and a state where the press contact is not normally accommodated in the connector (for example, the inclined contact is contained). When the check circuit is added, the staff member comes into contact with the press-contact portion at the time of press-contact and a closed circuit is formed by the harness and the check circuit, so that deformation of the press-contact portion can be detected.

Further, the conventional apparatus could not detect the broken wire of the electric wire due to the press-contact error, but according to the check circuit, the broken wire and the stuffer 48 come into contact with each other. Can be detected.

[0028]

As described above, according to the first harness manufacturing apparatus of the present invention, the length of the electric wire is measured by the roller disposed closer to the electric wire supply portion than the press contact portion, and the electric wire clamp is used. Since it is arranged reciprocally movable between the first and second positions, a compact harness manufacturing apparatus capable of manufacturing a feed-through type harness is configured.

Further, in the second harness manufacturing apparatus of the present invention, the first check pin and the second check pin are provided, and the continuity inspection unit for inspecting the continuity between them is provided. Is found, the connection of the electric wire to the connector is stopped thereafter, and the use of the electric wire and the connector is reduced.
