The electric wire 6 is conveyed by moving left and right, and this operation will be explained in detail later in the explanation of the operation.

Next, the instrument holding device 4 will be explained based on FIG. 1, FIG. 8, and FIG. 9. Air cylinders 58, 5 are installed at the four corners of the pallet transfer table 2, as shown in FIG.
9, 60, 61 are arranged, and pallet 3
A, 3B, and 3C are configured to be alternately moved to a wiring work position indicated by reference numeral 3A in FIG. 8 and a mounting position of a wired appliance by a worker 62 indicated by reference numeral 3B. At the appliance mounting position, for example, a plurality of electric appliances 63A, 63 are installed at positions as shown in the perspective view of the pallet after wiring in FIG.

At the wiring position, as shown in FIGS. 10 and 11, after peeling off the coating, the tip of the L-shaped electric wire 6 passes through the chamfered guide portion 64 of the electrical appliance 63A and connects to the terminal 65 or 66 and the wall surface. inserted between. The insertion operation will be described later.

The operation of the automatic wiring device configured as above will be explained. The worker 62 places the electrical appliances 63A on the pallet 3B (3A, 3C) at the appliance mounting position.
... and air cylinders 58, 59, 60, 6
1 as appropriate to create pallet 3A in Fig. 8.
Move to the wiring position where is located. and,
When the device is operated, the electric wire 6 pulled out from the storage container 5 by the guide rollers 18 and 19 is pulled out from the tension applying section 7.
Tension is applied at 8, and the curvature is removed by a strainer 8 before being sent out. At this time, Figure 13a
As shown in FIG. 13, the clamper 11A on the fixed side is fixed and the gripping portion is open, and the wire 6 that is sent out is projected from between the gripping portions, and as the belt 22 is driven by the motor 25, it is moved to the position shown in FIG. 13b. As shown, the gripper 11B on the movable side moves to the vicinity of the gripper 11A with its grip part open and picks up the electric wire 6.
grasp. The cutters 26 and 27 are retracted.
Then, when the motor 25 is rotated in the reverse direction, as shown in FIG.
As shown in , the gripper 11 moves along with the electric wire 6 and stops at a position of a predetermined dimension L. At this time, the fingers 56 and cutters 57 of both wiring hands 15 and 16 are open, so when only the fingers 55 are closed after the electric wire 6 has stopped, the electric wire 6 is connected to both fingers 55 as shown in FIG. 13d. It is gripped by both grippers 11A and 11B. So Katsuta 2
At steps 6 and 27, the electric wire 6 is cut to a predetermined length L. In addition,
As a result, the electric wire 6 on the gripper 11A side is in the state shown in FIG.
Repeat this operation at a predetermined timing.

After cutting the electric wire 6, the grippers 11A and 11B are released, and the arms 28 of both wiring hands 16 and 17 are moved by driving the motors 14 and 15, etc., and the electric wire 6, whose ends are gripped by both fingers 55, is placed on the pallet 3.
Move to the wiring position above A. When transporting the electric wire 6, it is desirable to keep the distance between the two wiring hands 16, 17 constant at all times in order to prevent the electric wire 6 from becoming too tensioned or sagging. Therefore, in this embodiment, for example, the electric wires 6 at positions P ₁ and P ₂ in FIG. 14 are connected by both wiring hands 16 and 17.
When moving to the wiring positions indicated by P ₃ and P ₄ , the first
As shown in Figure 5a, move the wiring hand 16 from P ₁ to P _3.
Then, after moving wiring hand 17 from P ₂ to P ₅ at the same acceleration and speed, wiring hand 1
By moving only wire 7 from P ₅ to P ₄ , excessive tension and slack in the wire 6 are minimized. Figure 15b shows the wire 6 from P ₁ , P ₂ to P ₃ , P ₄
In this case, too, after moving from P ₁ and P ₂ to P ₅ and P ₄ , one wiring hand 1
Move only 6 from P ₅ to P ₃ .

Next, a description will be given of the wire end processing operation in which the wire 6 that has been transported to the wiring position is stripped of its covering, molded, and then inserted into the terminal portion of the device. When the cutter 56 is closed at the same time as the wire reaches the wiring position, the circular blade 57 at the tip of the cutter 56 applies strong pressure to the end of the electric wire 6, thereby cutting the coating in an annular shape. Figures 16a and 17a show this state. Therefore, when the piston rod 37 of the air cylinder 36 is moved backward and the cutter holder 39 is moved outward, the blade 5
At the same time as the wire 7 strips off the annularly cut sheath, the engagement between the pin 48 and the stopper 47 is released, and the guide claw 51 rapidly descends along the guide rod 45 by the tensile force of the tension spring 50. The protrusion from the finger 55 is bent into an L shape. Figures 7, 12 and 16b, 17
Figure b shows this situation. In this case, as shown in FIG. 7, the V-groove 51a at the tip of the guide claw 51 holds and guides the core wire after the coating has been peeled off. Further, when the guide claw 51 is lowered, it descends while slidingly contacting the stopper 54 due to the bias of the tension spring 53.
After the end of the electric wire 6 is formed in this way, the finger holder 38, guide pawl 51, etc. are lowered integrally by the rotation of the motor 33 as shown in FIGS. 16c and 17c. , first first
As explained based on FIGS. 0 and 11, the electric wire 6
The core wire portion of the terminals 65, 66 and the electric appliance 63A...
...is inserted between it and the wall surface. In this insertion operation, as shown in FIGS. 17a, b, and c, a step is provided on the contact surface of the guide pawl 51 with respect to the stopper 54 to form a plate cam. It is pulled by the stopper 54
By coming into contact with the lower part of the plate cam, the V-groove 51a of the guide pawl 51 reliably guides the core wire portion, as shown in FIGS. 7 and 17b. That is, the first
The guide claw 51 moves by an amount indicated by the symbol t in FIG. 2 to guide the core wire portion. Further, when the finger 55 finishes descending as shown in FIG.
The finger 55 is pushed up against the spring force of 0.
inserts the core wire into the terminals 65, 66 of the appliances 63A, and at this time, the stopper 54 comes into contact with the high part of the plate cam, so the tip of the guide claw 51 escapes from the wire 6 in the horizontal direction, and the guide Even if the claw 51 rises, the covering of the electric wire 6 will not be damaged.

When the wire connection is completed in this manner, the finger 55 is opened to release the grip on the wire 6, and the finger holder 38, guide claw 51, etc. are raised integrally by driving the motor or the like. During this upward movement, the guide pawl 51 is lowered by the spring force of the tension spring 50, but until the tip part leaves the electric wire 6, it escapes from the electric wire 6 by the action of the plate cam, so that the sheathing is not damaged. . When the finger holder 38 and the like have finished rising, the cutter holder 39 is moved slightly backward by the air cylinder 36, and then the air cylinder 40 is operated and its stopper 43 moves the block 46 and the guide claw 51.
If you raise the air cylinder 40 and let out the air,
The guide pawl 51 returns to its original state in which the pin 48 is supported by the stopper 47. The wiring cycle is then completed by moving the wiring hands 16, 17 to the position for receiving the next wire by the movement of the arm 28.

The operations from supplying, transporting, and connecting the electric wire 6 have been described above, and by repeating these operations, each electric appliance 58A to 58 as shown in FIG.
Wiring between F is automatically performed.

Although this embodiment shows an example in which electric appliances are mounted on a pallet and wiring is made between electronic appliances, it is also possible to directly wire the electric appliances to a product on which they are mounted. In addition, in this embodiment, an example was shown in which the wires are transported to the wiring position, stopped, and then subjected to terminal processing such as stripping the coating. If only the insertion is performed, the wiring time can be shortened.
