Description

Detailed Description of the Invention Technical Field The present invention involves cutting a long coated wire into a predetermined length, peeling off the insulation coating at the end of the cut coated wire, and then removing the core wire from the end. The present invention relates to a covered wire insertion device that is inserted into an insertion hole of a printed circuit board.

BACKGROUND ART A printed circuit board as an object of work is placed in a horizontal plane, that is,
- The printed circuit board is placed on a table driven in the Y direction, and electrical components such as transistors, resistors, or capacitors are loaded onto this printed circuit board, and the terminals of each electrical component are automatically inserted into the insertion holes of the printed circuit board. Component mounting devices are already known. This component mounting device is used to automate the mounting of electrical components on many of the printed circuit boards used in electric carriers, which greatly contributes to the supply of stable products in large quantities without human error. .

As mentioned above, this type of component mounting device inserts a plurality of terminals established on a component body, such as a transistor, into an insertion hole of a printed circuit board, and a predetermined portion of the component body is inserted into the insertion hole of the component body. By chucking, it is possible to locate the terminals of the component by oneself, and therefore it is relatively easy to insert the terminals of the component into a predetermined position on the printed circuit board.

On the other hand, a large number of flexible coated wires are attached to the printed circuit board in addition to the above-mentioned electrical components. Specifically, a long coated wire wound around a reel or the like is cut to a predetermined length to obtain a cut coated wire, and the coated insulating material at both ends of the cut coated wire is peeled off to expose the core wire. The core wire is inserted into the insertion hole of the printed circuit board. Conventionally, this series of operations relied on human labor, which was particularly inefficient on production lines with a large amount of work. In addition, manual work has the disadvantage that there are large variations in the accuracy of installing the covered wire, resulting in a large number of defective products.

In order to compensate for the drawbacks of such manual work, a covered wire insertion device has recently been developed that automatically inserts the covered wire (see, for example, Japanese Patent Application No. 103,679/1982). Specifically, the coated wire insertion device includes a wire supply means for supplying a long coated wire, a cutting means for cutting the long coated wire into a predetermined length to obtain a cut coated wire, and a wire supply means for supplying a long coated wire; A wire conveying means that includes a gripping mechanism that grips the cut covered wire and conveys the cut covered wire along the process, a peeling means that peels off the insulation coating at the end of the cut covered wire, and a gripping mechanism that grasps the cut covered wire. and a wire transport/insertion means for transporting the cut coated wire onto the printed circuit board and inserting the exposed core wire at the end of the cut covered wire into the insertion hole of the printed circuit board.

By using such a covered wire insertion device, the efficiency and accuracy of the work of attaching the covered wire to the printed circuit board can be dramatically improved.

However, in the coated wire insertion device that has already been developed, the wire transport and insertion means has only one gripping means for gripping the cut covered wire. That is,
The gripping means receives, from the gripping mechanism (included in the wire transporting means), the first cut coated wire obtained by the cutting means and from which the coating insulation material at the end has been peeled off by the peeling means. In this state, it is moved onto the printed circuit board, and when the insertion of the cut covered wire into the printed circuit board is completed, it is moved back to the vicinity of the above-mentioned gripping mechanism, but during this time, the cut covered wire to be inserted next is They are forced to wait.

Therefore, the time it takes for the gripping means to move back from above the printed circuit board to the vicinity of the gripping mechanism (included in the wire transport means) and grip the next cut coated wire becomes so-called idle time, which reduces work efficiency. This was one of the issues that needed to be resolved in order to improve the situation.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned points, and its object is to provide a coated wire insertion device with even higher working efficiency.

The covered wire insertion device according to the present invention includes a wire feeding means for supplying a long covered wire, a cutting means for cutting the long covered wire into a predetermined length and cutting the cut covered wire, and a cutting means for cutting the cut covered wire into a predetermined length. a wire conveying means that includes a gripping mechanism that grips the cut covered wire and conveys the cut covered wire along the process; a peeling means that peels off the insulation coating at the end of the cut covered wire; wire transport and insertion means for gripping and transporting the cut covered wire onto the printed circuit board and inserting the exposed core wire at the end of the cut covered wire into the insertion hole of the printed circuit board; a rotating body capable of rotating around an axis parallel to the rotating body; a driving means for rotationally driving the rotating body; a gripping means which is respectively disposed and movable along the rotation center axis of the rotating body and grips an end portion of the cut covered wire; and a gripping means for inserting the exposed core wire of the cut covered wire into the insertion hole of the printed circuit board It is characterized by having a gripping means moving means for moving the means.

Each index chuck 38, an index table 34 supporting each index chuck, a motor 36 (shown in FIG. 5, etc.) for rotationally driving the index table, and a power transmission mechanism 35 (shown in FIG. 5, etc.) )and,
These and related peripheral small members constitute a wire transport means that transports the cut covered wire 41 through each process such as a terminal crimping process and a continuity check process, which will be described later. That is, as is clear from FIG. 7, each index chuck 38 provided on the index table 34 is moved to the seventh position by the rotation of the index table.
Starting from the angular position indicated by reference numeral 51 in the figure, it moves counterclockwise (in the direction of arrow J) in angular pitch increments of 60°, successively radiates 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 chuck 38 is attached to the holding member 59 via a bottle 60 so as to be swingable relative to each other, and each pair is attached to the holding member 59. It has two pairs of gripping claws 61 and 62 that grip one end of the cut covered wire 41 (see FIG. 8).

As is particularly clear from FIGS. 14(a) and 14(b), intermediate levers 64, 65 are rotatably attached to the rear end of each of the gripping claws 61, 62 via a pin 63 at one end thereof. and each other end of the lever is attached to the bottle 6.
It is pivoted by 6. As shown in FIGS. 12 and 13, the bottle 66 is pivotally connected to the tip of a rod 67. As shown in FIGS.

That is, the reciprocating movement of the rod 67 causes the gripping claws 61 to
．． 62 can be opened and closed. The rod 67 is formed integrally with a piston 68 that is fitted into a cylinder portion formed by parts of the index table 34 and the holding member 59. Further, a coil spring 69 is compressed within the cylinder portion and provides a bias tension to the rod 67.

The above cylinder part is like this, index table 3
4 and a portion of the holding member 59, the index table 34 and the index chuck 3
8 has been made smaller and the structure has been simplified.

Furthermore, 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 piston 68 is fitted, through the index boss 31 as shown in FIG.

A terminal supply means is configured to supply the terminal 42 to be fixed to the exposed core wire portion (see FIG. 8(C)).

As shown in FIG. 7, the continuity of the cut covered wire 41 (see FIG. 8(d)), which has been crimped with the terminal 42, is checked corresponding to the angular position 54 following the angular position 53 described above. A continuity check device 86 is arranged.

As shown in FIGS. 3, 4, and 6, a continuity check device 8 is provided in front of the index table 34.
The cut coated wire 41 (see FIG. 8 (d+)) which has completed the continuity check in step 6 is gripped and conveyed onto the printed circuit board 3 (shown in the first figure), and the end of the cut coated wire is held as shown in FIG.
As shown in FIG. 2, a wire transport/insertion device 88 for inserting into the insertion hole of the printed circuit board 3 is arranged. As is clear from the figure, the wire rod conveyance/insertion device 88 as a whole consists of a support plate 3 provided on the workbench 2 together with a frame 29.
Supported by 0.

As shown in Figure @15, a wire transfer device 90 is disposed corresponding to the angular position 55 following the angular displacement @54 described above. This wire transfer device 90 grips the cut covered wire 41 that has been checked for continuity, receives it from the index chuck 38, and transfers it to the wire transfer and insertion device 88.
The wire is transported to the position where the wire is held.

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, the wire removing device 9 is transferred from the wire feeding device 77 described above.
Each of the devices up to 1 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 40 is wound. The pulley 76 is rotationally driven by a motor 95 with an electromagnetic brake, which is also shown in FIG. As shown in FIGS. 16 and 17, a lever A96 is arranged on the outer surface of the front surface of the support box 94, and is swingably attached to the support box 94 by a pin 97 at one end thereof. ing. A pulley 98 is provided at the free end of the lever A96, and the long coated wire 40 is hooked around this pulley 98 and two fixed pulleys 99, 100 fixed to the support box 94. In addition, each fixed pulley 99°100 has presser pulleys 102 and 103.
are in contact with each other with the urging force of coil springs 102a and 103a. 8 presser pulley 102.103
The arm members 102c and 103 are swingably attached to the support box 94 by the bins 102b and 103b.
provided at the free end of c.

As shown in FIG. 17, a pin 97 supporting lever A96 reaches the inner surface of support box 94, and another lever 8104 is also fixed to this pin. In addition, a pair of stoppers 105a are provided near the lever B104.
105b is arranged, and the swinging movement of lever B104 and lever A96 is restricted within a predetermined range. Lever B1
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 B1.
04 are arranged corresponding to the three digitorum angle positions.

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

When the long coated wire 40 is pulled out in the direction of arrow P, the pulling force causes the lever A96 to swing clockwise in FIG. 16 by a predetermined angle. Also, lever B
104 is swung counterclockwise in FIG.

At this time, if the long coated wire 40 is slack between the reel 76 and the fixed pulley 99, the lever A96 and the lever B
104 is instantly returned to the first position shown in FIGS. 16 and 17 by a coil spring 106 (shown in FIG. 17). Therefore, the detected element 104a provided on the lever B104 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.

If the long coated wire 40 is not loosened between the reel 76 and the fixed pulley 99 but is stretched, the lever B104 remains oscillated, and the detected element 104a is removed from the position detected 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 length. 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 movably attached to the guide rail.

As is particularly clear from FIG.
A chuck 116 serving as a gripping mechanism for gripping 0 is rotatably attached via a ball bearing or the like.

Note that the rotation center axis of the chuck 116 extends in a direction perpendicular to the two arrow directions, 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 through a bin 118a so as to be able to swing freely relative to each other and grip the tip of the long coated wire 40. ing. Note that the long coated wire 40 supplied from the wire supply device 77 is passed through a plurality of rollers 119 and a nozzle 120, as shown in FIG.
will be guided through. As is especially clear from Figure 21,
A pair of intermediate levers 122 are rotatably attached at one end to the rear end of each gripping claw 118 via a pin 122a, and each other end of the intermediate lever is attached to a pin 122a. 122b. This bottle 122b
is connected to the tip of the rod 123 via a coupler 123a. That is, the gripping 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 FIGS. 19 and 20, the chuck 11
A binion 125 is fixed to the rear end portion of the wheel 6. On the other hand, as shown in FIG. 18, a rack member 126 that engages with the binion 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 slidably attached to the guide shaft 128, and a guide rail 130 that is attached to the slider and extends vertically (in the direction of arrow Z and the opposite direction) is provided to protrude from the rack member 126. It is in sliding contact with the bottle 131. That is, slider 1
By reciprocating the pinion 29, the pinion 125 and therefore the chuck 116 are 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 is connected to one end of the swing lever 134 for swinging the swing lever. This rod 13
5 is movable in the front-rear direction (arrow Y direction and the opposite direction), and is connected to the drive source 1 shown in FIGS. 4 and 5.
36 as appropriate.

On the other hand, as is clear from FIGS. 7, 15, and 18, the rod 133 connected to the slider 129 that controls the rotation of the chuck 116 is connected to another rod 138 via a swing plate 139. There is. Swing plate 139
is mounted on the workbench 2 by a bin 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 FIG. 4, FIG. 7, and FIG. 19, near the tip of the chuck 116, there is a hole for hooking the long coated wire 40 (see FIG. 19, etc.) pulled out by the chuck. A roller 141 is arranged. Although not described in detail, this roller 141 is appropriately moved in the vertical direction (arrow Z direction and the opposite direction) and arrow Q direction by a predetermined mechanism.

As shown in FIGS. 15 and 19, the chuck 11
6, a cutting mechanism 142 is arranged below the roller 141 to cut the long coated wire 40 (see FIG. 19, etc.) at a predetermined position.

The chuck 116 described above, a chuck moving means for moving the chuck 116 including the guide rail 114 and the guide shaft 128, a roller 141, a mechanism (not detailed) for moving the roller, and a cutting mechanism 142. Thus, the wire cutting bag M75 shown in FIG. 15 and the like is constructed.

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 process, the roller 141 is moved upward (in the direction of arrow Z) by a predetermined distance, and the drawn out portion of the long covered wire 40 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). The cutting wave rN obtained in this way
The at material 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, the peeling device 79 provided corresponding to the angular position 52 will be described in detail.

As shown in FIGS. 24 and 25, the peeling device 79
