Abstract

PURPOSE:To shorten a required time for insertion per electric wire and to reduce a size in an electric wire inserting device by synchronizing a crimp terminal insertion accompanying action by the other device with a crimp terminal inserting action by one device in a pair of crimp terminal inserting devices. CONSTITUTION:A crimp terminal B is mounted in the front end of an electric wire A by a crimp terminal caulking device 3, and the electric wire A is pulled out by a chuck main body 7c of an electric wire puller device 7. Then, the electric wire A is clamped by the chuck jaw 5f of an electric wire front end part inserting device 5, and a rotary driving part 5d is rotated so that the terminal B properly faces a housing whose position is regulated in the predetermined position. The forward/backward movement mechanism of the insertion device 5 is actuated so that the terminal B is inserted into the predetermined position in the housing. During this action of the insertion device 5, the similar action by an electric wire rear end part insertion machine is synchronously carried out, so that the crimp terminal B is mounted in the rear end of the electric wire A by the caulking device 3. In this way, a required time for insertion can be shortened by the synchronous actions of a pair of crimp terminal insertion devices.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire insertion device,
More specifically, in order to electrically connect a plurality of electronic devices to each other, an electric wire is inserted into a housing such as a connector based on a predetermined relative relationship to achieve electrical connection between the housings. Regarding the device.

[0002]

2. Description of the Related Art Conventionally, with the spread of microcomputers and the like, a control unit for electrically controlling the operation of each component of an industrial machine, an automobile, etc. is arranged near the position to be controlled, In order to exchange signals between the control units, it has become common to electrically connect the control units to each other using a plurality of connectors electrically connected by a necessary number of wires. Specifically, a plurality of connectors to which a plurality of electric wires are connected are provided, and a mating connector is defined for each electric wire of each connector.

Therefore, as a work of mounting an electric wire for electrically connecting a plurality of connectors to each other, crimping terminals are crimped to both ends of the electric wire which has been cut into a predetermined length by using crimping terminals. A method of crimping and inserting each crimping terminal into a desired portion of a desired connector by a manual operation of an operator is adopted.

[0004]

When the electric wire is inserted into the connector by the above method, not only the time required for inserting the electric wire is considerably long, but also the electric wire is required to be inserted into the connector. There is a disadvantage that there is a high possibility that an insertion error of will occur. In consideration of such inconvenience, inserting a wire into a connector using a multi-axis general-purpose industrial robot (specifically, inserting a crimp terminal)
It is possible to do. However, in this case, the number of connectors into which electric wires should be inserted is generally quite large, and the electric wire insertion positions in each connector are considerably large, and furthermore, both ends of each electric wire are inserted in the corresponding positions of the connector. Since it must be done, the time required to insert both ends of one wire into the corresponding positions of the connector becomes considerably long (for example, the time required to insert each wire takes about 30 seconds or more). There is an inconvenience that

Further, if the number of connectors into which electric wires are to be inserted increases, it is necessary to employ an industrial robot having a wide operable range, which causes an inconvenience that the electric wire inserting device becomes large as a whole.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an electric wire insertion device capable of significantly shortening the time required for insertion of an electric wire and relatively reducing the size thereof as a whole. It is an object.

[0007]

In order to achieve the above object, an electric wire insertion device according to claim 1 has a terminal mounting device for mounting crimp terminals on both ends of a wire of a predetermined length, and a terminal mounting device for both ends. A housing holding device that holds the housing to which the wire with the crimp terminal is to be mounted in a positionally adjustable manner, and the crimp terminal mounted on one end of the wire is directly or indirectly grasped and inserted into the corresponding part of the housing. A first crimp terminal insertion device, a second crimp terminal insertion device that directly or indirectly grips a crimp terminal attached to the other end of the electric wire, and inserts the crimp terminal into a corresponding portion of the housing, and one of the crimp terminal insertion devices And a control device for controlling both crimping terminal inserting devices so that the crimping terminal inserting operation by the other crimping terminal inserting device is performed in synchronization with the crimping terminal inserting operation. Here, the operation associated with insertion of the crimp terminal is used as a concept including an operation not directly involved in insertion of the crimp terminal, and also includes a returning operation after insertion of the crimp terminal.

[0008]

According to the electric wire inserting device of the present invention, crimping terminals are attached to both ends of the electric wire of a predetermined length by the terminal attaching device, and the housing holding device holds the position adjustably and crimps the both ends. A housing, represented by a connector, in which an electric wire on which a terminal is mounted is to be mounted is moved in correspondence with a crimp terminal insertion planned position. Then, under the control of the control device, the crimp terminal inserting operation by the other is performed in synchronization with the crimp terminal inserting operation by one of the pair of crimp terminal inserting devices. Therefore, the required time can be shortened by the synchronous operation of the pair of crimp terminal insertion devices. Since the operating range of the crimp terminal inserting device can be reduced corresponding to the moving range of the housing by the housing moving device, it is possible to achieve downsizing as a whole.

The operation of the electric wire insertion device having the above configuration will be described below with reference to the timing chart shown in FIG. In FIG. 10, the operation sequence is indicated by an arrow.

The crimping terminal caulking machine 3 is used to mount the crimping terminal B on the tip of the electric wire A, and the slide member 7b is then used to advance the chuck body 7c of the electric wire drawing machine 7 to move the mounted crimping terminal B to the chuck claw 7d. The electric wire A is pulled out by gripping with and by retracting the chuck body 7c. After that, the chuck main body 5e is moved forward by operating the advancing / retreating mechanism 5g of the electric wire tip portion inserting machine 5, and the vicinity of the portion of the electric wire drawing machine 7 which is gripped by the chuck claw 7d is gripped by the chuck claw 5f. Next, the chuck main body 5e is retracted by the advancing / retreating mechanism 5g, and the first turning drive unit 5a is operated, whereby the chuck main body 5e is moved.
To face the housing holding device 2. During this time, the posture of the chuck claw 5f is controlled by operating the second turning drive unit 5d as necessary (this operation is not shown in the timing chart). afterwards,
The chuck body 5e is moved forward by operating the advancing / retreating mechanism 5g of the wire tip insertion device 5, and the crimp terminal B close to the grip position by the chuck claw 5f is moved to a predetermined position on the housing carrier main body 2c. The chuck body 5e is inserted into the position, the gripping state of the chuck claw 5f is released, and further the chuck main body 5e is retracted by the advancing / retreating mechanism 5g. It should be noted that the wire feeding roller 9 operates to feed the wire A from the backward movement of the chuck body 7c of the wire drawing machine 7 to the forward movement of the chuck body 5e for inserting the crimp terminal B into the housing 8. This prevents an excessive tensile force from acting. of course,
The wire A of the required length is also delivered.

By performing the above series of operations, the crimp terminal B at the tip of the electric wire A is inserted into the housing 8 at a predetermined position. Further, before the chuck body 5e is finally retracted, the wire crimping machine 3 operates to mount the crimp terminal B on the rear end of the wire A as well. By operating the electric wire rear end inserting machine 4 in the same manner as the electric wire front end inserting machine 5, the crimp terminal B at the rear end of the electric wire A can be inserted into a predetermined position of the corresponding housing 8. However, in this case, it is not necessary to operate the wire drawing machine 7 because the gripped state by the chuck claw 4f is suitable for the final insertion operation.

Even when the crimp terminal B mounted on the electric wire A is inserted into the housing 8 by any of the above-mentioned inserters, the posture of each inserter at the time of inserting work is fixed, so that the housing carrier main body 2c is placed horizontally. Direction and / or vertical direction to move the housing 8 into which the crimp terminal B is to be inserted to a predetermined position,
The insertion work of the crimp terminal B can be performed without any inconvenience.

Further, while one of the inserting machines is performing an operation for inserting the crimp terminal, the other inserting machine performs a returning operation (a turning operation in a reverse direction by the first turning drive section),
The insertion work of the crimp terminal B is sequentially performed with almost no dead time. Hereinafter, by repeating the above series of operations, both ends of a large number of electric wires A can be sequentially inserted into the corresponding housing 8.

Further, the tact time per electric wire by the electric wire insertion device having the above-mentioned structure can be reduced to about 1/4 of the tact time per electric wire by the general-purpose industrial robot having the multi-axis structure.

[0021]

As described above, according to the first aspect of the present invention, the required time can be shortened by the synchronous operation of the pair of crimp terminal insertion devices, and the crimp terminal insertion device can be adapted to the movement range of the housing by the housing movement device. It has a unique effect that the operating range of can be reduced and the miniaturization can be achieved as a whole.
