A wire rod i transport means for transporting the wire rod 41 is configured. In other words, as is clear from FIG. 7, each index chuck 38 provided on the index table 34 is rotated to the seventh position.
Starting from the angular position indicated by @ reference symbol 51 in the figure, the movement counterclockwise (in the direction of arrow J) by an angular pitch of 60'', sequentially passes through the angular positions 52 to 56 following the starting point, and returns to the angular position 51 ( (starting point).

The structure of the index chuck 38 mentioned above will be explained in detail.

As shown in FIGS. 12 and 13, the index chucks 38 are attached to five holding members 59 via bins 60 so as to be swingable relative to each other, and one pair each. has two pairs of gripping claws 61 and 62 that grip one end of the cut coated wire 41 (see FIG. 8).

8 has been made smaller and the structure has been simplified.

In addition, since the movement stroke of the piston 68 and therefore the rod 67 is determined by the bush 70 interposed between the index table 34 and the holding member 59, the movement stroke of the piston 68 and therefore the rod 67 is adjusted, that is, the opening and closing of each gripping claw 61, 62 is controlled. No adjustment necessary. Therefore, each index chuck 3
8 can be interchanged without any adjustment. The compressed air is supplied into the cylinder portion into which the screws 1 to 68 are fitted, as shown in FIG.

The reel 82 and the drive IJJ mechanism 84 form a terminal supplying means for supplying the gable terminal 42 fixed to the exposed core portion of the cut and coated wire 41 (see FIG. 8(C)).

As shown in FIG. 7, a continuity check device checks the continuity of the cut covered wire 41 (see figure m8 + d+) that has completed crimping of the terminal 42, corresponding to the angular position 54 following the angular position 53 described above. 86 are arranged.

As shown in FIGS. 3, 4, and 6, a continuity check device 8 is provided in front of the index table 34.
The printed circuit board 3 (shown in the first figure) is held while holding the cut coated wire 41 (see Fig. 8 (see small)) that has completed the continuity check in step 6.
A wire transport/insertion device 88 is disposed for transporting the cut coated wire upward and inserting the end of the cut coated wire into the insertion hole of the printed circuit board 3 as shown in FIG. 8(Q). As is clear from the figure, the wire rod conveyance/insertion device 88 as a whole consists of a support plate 30 provided on the workbench 2 together with the frame 29.
Supported by

As shown in FIG. 15 (corresponding to the angular position 55 following the aforementioned angular position 54), a wire rod transfer device 90 is arranged. , take the serial number from the index chuck 38, and insert it into the wire transport/insertion device 1.
This is to transport the wire to the wire gripping position by ff88.

Further, a wire removing device 91 shown in FIG. 4 is arranged corresponding to the angular position 56 following the angular position 55 described above. The wire removal device 91 serves to remove the cut covered wire 41 in a predetermined direction when the continuity check by the continuity check device 86 fails.

Next, each of the devices from the wire supply device i77 to the wire removal device ff191 will be described in detail.

First, the wire supply device 77 shown in FIGS. 1 to 3
I will explain about it. As is particularly clear from FIGS. 16 and 17, the wire supply device 77 has a support box 94 that supports the pulley 76 around which the long covered wire 4440 is wound. Note that the boo 976 is rotationally driven by the electromagnetic play key→motor 95 also shown in FIG. 16th
As shown in the drawings and FIG. 17, a lever A96 is arranged on the outer surface of the front surface of the support box 94, and
One end thereof is swingably attached to a support box 94 by a pin 97. A boot 998 is provided at the free end of the lever Δ96, and the long coated wire 40 is hooked around this pulley 98 and two fixed pulleys 99 and 100 fixed to the support box 94. In addition, each fixed pulley 99° 100 has a presser pulley 102 and 1
03 are inadvertently brought into contact with each other due to the biasing force of the coil springs 102a and 103a. 6 presser pulley 102.1
03 is the support box 9 by the bins 102b and 103b.
an arm member 102c swingably attached to 4;
It is provided at the free end of 103c.

As shown in FIG. 17, a bin 97 supporting the lever Δ96 reaches the inner surface of the support box 94, and another lever B104 is also fixed to the bin. Na a3,
A pair of stoppers 1058. are located near the lever B104.
105b is arranged, and the swinging movement of lever B104 and lever A96 is restricted within a predetermined range. lever 81
A coil spring 106 is connected to the free end of the lever B for biasing the lever B clockwise in FIG. A detected element 104a is attached to the free end of the lever B104, and three sensors 108 to 110 for detecting this detected element 104a are connected to the lever 8.
104 are arranged corresponding to the three swing angle positions.

The operation of the wire supply device 77 having the above configuration will be explained.

When the long covered wire 40 is pulled out in the direction of arrow P, the lever A96 is swung by a predetermined angle C in the clockwise direction in FIG. 16 due to the pulling force. Further, the lever B104 is swung counterclockwise in FIG. 17. At this time, if the long coated wire 40 is loosened between the reel 76 and the fixed pulley 99, the lever A96 and the lever B104 are moved by the coil spring 106 (shown in FIG. 17) into the positions shown in FIGS. 16 and 17. It can be returned to the first position instantly. Therefore, the detected element 104a installed on the lever 8104 is detected by the sensor 108, so that the electromagnetic brake motor 95 does not operate and the long coated wire 40 is not fed out from the reel 76.

When the long coated wire 40 is not loosened between the reel 76 and the fixed pulley 99 and is stretched, the lever B104 remains oscillated, and the detected element 104a is removed from the detection position by the sensor 108 for a predetermined period of time or more. I will do it. Then, the motor 95 with an electromagnetic brake operates, and the long coated wire 40 is fed out from the reel 76 by a predetermined distance. As a result, the lever B104 returns to the state shown in FIG.
The detected element 104a is detected by the sensor 108, and the electromagnetic brake motor 95 stops again. Also, when the lever 8104 swings considerably and the detected element 104a is detected by the sensor 109, the electromagnetic brake motor 95 stops. When the long coated wire 40 wound around the reel 76 runs out, the lever B104 swings even more due to the force of pulling out the wire in the direction of arrow P, since the end of the long coated wire is connected to the reel 76. However, the detected element 104a is detected by the sensor 110. This detection signal becomes a signal indicating that the long coated wire 40 has run out, and the reel 76 is replaced with a new one.

Next, the wire cutting device 75 shown in FIGS. 4, 7, and 15 will be described in detail.

As shown in FIGS. 18 and 19, the wire cutting device 75 is cut in the vertical direction (arrow Z direction and the opposite direction).
It has a guide rail 114 that extends at and is fixed to the workbench 2 (see FIGS. 1 and 7, etc.), and a slider 115 that is slidably attached to the guide rail.

As is particularly clear from FIG.
A gripping RF machine groove 116 for gripping 0 is rotatably attached via a ball bearing or the like. Note that the rotation center axis of the chuck 116 is aligned in a direction perpendicular to the direction of arrow Zh, that is, in a horizontal direction. The chuck 116 includes a holding member 117 and a pair of gripping claws 118 that are attached to the holding member 117 via a pin 118a so as to be able to swing freely relative to each other and grip the tip of the long coated wire 40. have. Incidentally, the long coated wire 40 supplied from the wire supply device 77 is fed through a plurality of rollers 119 and a nozzle 12, as shown in FIG.
Guided through 0. As is particularly clear from FIG. 21, a pair of intermediate levers 122 are rotatably attached to the rear end of each gripping claw 118 via a pin 122a, and the six intermediate levers 122 are rotatably attached at one end thereof. Each other end of the lever is pivoted by a pin 122b. This bottle 122
b is connected to the tip of the rod 123 via a coverlet 123a. In other words, the grip claws 118 are opened and closed by the reciprocating movement of the rod 123. The rod 118 is driven by a cylinder mechanism formed within the holding member 117.

As shown in Figures 19 and 20,
A pinion 125 is fixed to the rear end of the motor 16. On the other hand, as shown in FIG. 18, a rack member 126 that engages with the pinion is attached to the slider 115 so as to be able to reciprocate in the horizontal direction. A pair of guide shafts 128 are arranged behind the rack member 126, extending in the horizontal direction and fixed to the workbench 2 (see FIG. 7, etc.) via a bracket 127. A slider 129 is attached to the guide shaft 128.
But li! ! A guide rail 130 is movably attached to the slider and extends vertically (in the direction of arrow Z and in the opposite direction) to the rack member 126.
It is in sliding contact with the bottle 131 which is provided protrudingly. In other words, as the slider 129 reciprocates, the binion 125
Therefore, the chuck 116 is rotated.

The slider 129 reciprocates by reciprocating a rod 133 connected to the slider. Further, as described above, the chuck 116 is capable of reciprocating in the up and down direction (direction of arrow Z and the opposite direction) together with the slider 115 that supports the chuck. This is achieved by swinging the dogleg-shaped swinging lever 134 shown in FIG. As shown in FIGS. 7 and 15, a rod 135 for swinging the swing lever is connected to one end of the swing lever 134. As shown in FIGS. This rod 1
35 is movable in the front-rear direction (in the direction of arrow Y and the opposite direction), and is appropriately driven by a drive source 136 shown in FIGS. 4 and 5.

On the other hand, as is clear from FIG. 7, FIG. 15, and FIG. ing. Swing plate 139
is mounted on the workbench 2 by a pin 139a. Like the rod 135 on the right side, the rod 138 is also capable of reciprocating in the front-rear direction, and is driven by a drive source 136 shown in FIGS. 4 and 5.

As shown in FIGS. 4, 7, and 19, near the tip of the chuck 116 is a roller 141 for hooking the long covered wire 40 (see FIG. 19, etc.) pulled out by the chuck. is located. Although not described in detail, this roller 141 is appropriately moved by a predetermined lN4 in the vertical direction (two directions of arrows and the opposite direction) and the direction of arrow Q.

As shown in FIGS. 15 and 19, the chuck 11
A cutting mechanism 142 for cutting the long covered wire 40 (see FIG. 19, etc.) at a predetermined position is disposed near the roller 141 and below the roller 141.

The above-mentioned chuck 116, a chuck moving means for moving the chuck 116 including the guide rail 114 and the guide shaft 128, the roller 141, a mechanism for moving the roller (not detailed), and the cutting mechanism 142, A wire cutting device 75 shown in FIG. 15 and the like is configured.

The operation of the wire cutting device 75 described above will be explained.

As shown in FIG. 23, the long coated wire 40 drawn out by the chuck 116 through the nozzle 120 (also shown in FIG. 19) is hung on the roller 141 by vertical movement and rotation of the chuck. During this movement, the O-ra 141 is moved upward (in the direction of arrow Z) by a predetermined distance, and the elongated covered wire 40 that has been pulled out is formed into an inverted U-shape.

Then, the cutting mechanism 142 operates to cut the long covered wire into a predetermined length, thereby obtaining the cut covered wire 41 shown in FIG. 8+b+. Cutting wave II obtained in this way
The wire 41 is gripped by the index chuck 38 at an angular position 51 (shown in the seventh figure) and conveyed to the next angular position 52.

Next, a peeling device 7 provided corresponding to the angular position 52
9 will be explained in detail.

As shown in FIGS. 24 and 25, the peeling device 79
has a pair of guide shafts 146 extending in the vertical direction (arrow Z direction and the opposite direction), and a peeling chuck 147 slidably attached to the guide shafts. As also shown in FIG. 26, the peeling chuck 14
7 is attached to the holding member 148 through a pin 149 so as to be able to swing freely relative to each other, and each pair of the parts 2 peels off the insulating material at the end of the cut covered wire 41. It has a pair of peeling claws 150 and 151. Both peeling claws 150 and 151 are opened and closed by a cylinder mechanism including a rod 153.

As is particularly clear from FIG. 25, a bracket 155 is provided on the side of the peeling chuck 147, and a rotary lever 156 is rotatably attached to the upper end of the bracket by a pin 156a. This rotating lever 1
The free end of 56 is pivotally attached to bracket 147a on peel chuck 147 by bolt 156b. At the other free end of the rotary lever 156, there is a rod 157 that can reciprocate in the front-rear direction (arrow Y direction and the opposite direction).
It is pivotally attached to one end of the . The other free end of the rotary lever 156 is provided with a coil spring 156C for biasing the rotary lever clockwise in FIG.
are connected. In other words, as the rod 157 reciprocates, the rotary lever 156 rotates, thereby causing the peeling chuck 147 to move up and down. As is clear from FIGS. 5 and 15, the rod 157 is driven by the drive source 136 also shown in FIG. Note that, as shown in FIG. 25, a coil spring 14 that directly urges the peeling chuck 147 upward
7C is also provided.

The operation of the above-mentioned peeling device 79 will be explained.

When the U-shaped cut coated wire 41 (see FIG. 8(b)) obtained by the above-mentioned wire cutting device 11ff75 is gripped by the index chuck 38 and conveyed to the position of the peeling device 79, first, the peeling is performed. Peeling claws 151, 152 of the device grip the ends of the cut coated wire 41. In this state f11, the peeling chirek 147 is moved downward, and the cut coated wire 4
The insulating material at the end of the cut wire 41 is peeled off, and the cut covered wire 41 is in the state shown in FIG. 8(C). Note that the peeled insulating material is located at position 1 below the peeling chuck 147.
