Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a terminal crimping machine for crimping a terminal by continuously conveying a terminal continuous body in which a plurality of crimping terminals are connected in a chain at a predetermined feed pitch.

[0002]

2. Description of the Related Art FIG. 6 is a plan view of a terminal chain used in this type of terminal crimping machine. This terminal chain body 1 is configured to include a plurality of crimp terminals 3 and two strip-shaped carriers 5 and 7 that connect the plurality of crimp terminals 3 in parallel with each other. On one side of each crimp terminal 3, a connecting portion 3a to be connected to another electric device is formed, and on the other side, a crimp portion 3b to be crimped to the wire end 11a of a predetermined electric wire 11 (see FIG. 7) is provided. Has been formed. The crimp terminals 3 and the carriers 5 and 7 are connected to each other by the cut-off portions 13 and 15 extending on the edge portions of the crimp terminals 3 on the connection portion 3a side and the crimp portion 3b side.

The electric wire 11 to which the crimp terminal 3 is crimped is a high tension cable (high voltage resistance electric wire for automobiles),
The two crimp portions 3b of each crimp terminal 3 have two barrel portions 3c,
3d is provided. In addition, in FIG. 6, A indicates the distance between the separated portions 13 and 15 of each crimp terminal 3 in the terminal chain 1 (width of the crimp terminal 3), and B indicates the terminal crimping machine of the terminal chain 1 which will be described later. Shows the transport direction in C, and C is the terminal chain 1
Shows the width direction of.

The crimping of the crimp terminals 3 of the terminal chain 1 to the electric wire 11 is performed by a predetermined terminal crimping machine. In the terminal crimping machine, while transporting the terminal chain 1 at a predetermined feed pitch by a predetermined terminal transport mechanism,
Separate each crimp terminal 3 from the carriers 5 and 7,
Exposed conductor 11b, as shown in FIG.
The crimp portion 3b of each crimp terminal 3 into which the electric wire end 11a of the electric wire 11 is inserted in a state where the wire is bent is crimped as shown in FIG.

Here, an epoxy resin adhesive is pre-applied to the inside of the crimping portion 3b of each crimping terminal 3 by a predetermined adhesive application mechanism, and the crimped crimping terminal 3 is more firmly connected to the wire end 11a. It is supposed to be fixed.

In such a terminal crimping machine, when the terminal chain 1 is transported by the terminal transport mechanism, the terminal chain 1 and the applicator for crimping the terminals are positioned by a predetermined guide mechanism so as to position the terminal chain 1. The body 1 is positioned and held so as to be sandwiched from both sides.

This guide mechanism is generally composed of a fixed guide body fixed at a predetermined position and a movable guide body whose position can be adjusted so as to move toward and away from the fixed guide body. By adjusting the distance between the guide body and the moving guide body, different types of terminal chain bodies 1
It can be adapted to.

With respect to this point, in the conventional terminal crimping machine, the moving guide body is fixed to the female screw body screwed to the bolt body rotatably fixed at a predetermined fixing position, and the bolt body is manually fixed. By driving the moving guide body in the reverse direction, the distance between the fixed guide body and the moving guide body is adjusted.

[0009]

However, in the conventional terminal crimping machine, when the type of the terminal chain 1 is changed and the like, the bolt body is manually rotated so that the distance between the fixed guide body and the movable guide body is increased. There is a problem in that it needs to be adjusted and it takes time to set.

Further, if the gap between the fixed guide body and the movable guide body is set too wide, the positioning of the terminal chain body 1 becomes insufficient. On the other hand, if the gap is set too narrow, the terminal chain body 1 becomes the guide bodies. Although it can be caught and cannot be transported smoothly, in the conventional terminal crimping machine, the terminal crimping is performed with the gap between the fixed guide body and the moving guide body being kept constant. There is a problem that the above-described inconvenience is likely to occur in positioning or transporting the chain 1.

Therefore, in view of the above problems, the first aspect of the present invention
It is an object of the present invention to provide a terminal crimping machine that does not take time and effort to change the setting of the interval between the individual guide body that guides the terminal chain body by sandwiching it from both sides and the moving guide body.

Furthermore, when changing the type of the terminal chain 1,
By performing a predetermined operation input through the input receiving unit 58 under the control of the control unit 59, the distance D of the guide mechanism 31 and the position of the first cutting mechanism 33 are values corresponding to the new type of the terminal chain 1. And the position is automatically changed.

As described above, according to this embodiment, the moving guide body 29 is driven by the driving force of the motor 55 of the guide drive mechanism 35, so that the fixed guide body 27 and the moving guide body 29 are used. It does not take time to change the setting of the interval D.

Further, since the interval D of the guide mechanism 31 is opened and closed in conjunction with the feeding operation of the terminal transport mechanism 25, the terminal chain body 1 is smoothly transported while the terminal chain body 1 is being transported. The terminal can be crimped in a good state by favorably positioning in the width direction C.

Further, the first cutting mechanism 33 for cutting the separating portion 13 on the connecting portion 3a side of each crimping terminal 3 in the terminal chain 1 and the moving guide body 29 constitute the guide driving mechanism 3.
Since it is designed to be driven integrally by 5,
The configuration can be simplified as compared with the case where the drive mechanism is provided on both the cutting mechanism 33 and the movement guide body 29.

[0042]

According to the first aspect of the present invention, the moving guide body is driven in the direction of moving toward and away from the fixed guide body by the driving force of the power source of the guide drive mechanism.

According to the second aspect of the present invention, the moving guide body is driven by the guide drive mechanism in association with the feeding operation of the terminal transport mechanism, and the distance between the fixed guide body and the moving guide body is set to the terminal chain. When the body is being transported, the terminal chain is opened so that it can be transported smoothly, and when the body is stopped, the gap is closed and the terminal chain is positioned and held. Therefore, the terminal chain can be satisfactorily positioned in the width direction to crimp the terminal while smoothly transporting the terminal chain.

According to the third aspect of the invention, the first cutting mechanism for cutting the separation portion on the connection portion side of each crimp terminal in the terminal chain and the moving guide body are fixed guides by the guide drive mechanism. Since it is driven integrally in the direction of approaching and separating from the body, the configuration can be simplified as compared with the case where the drive mechanism is provided for both the first cutting mechanism and the movement guide body.
