The frames 7 and 47 are connected to both frames 11 and 12. For the wire guide 43 and the depressing device 44, refer to Japanese Patent Application No.
No. 06472 has been proposed.

Above the electric wire 4, an electric wire pressing blade 48 is provided.
The electric wire connection portions 6 and 7 each including a crimping punch portion 49 (see FIG. 14 and integral with or separate from the electric wire pressing blade 48) are provided.
When the sliders 51, 51 are lowered by the driving of the servomotors 50, 50 of the press-connecting machines 2, 3, the electric wire connecting parts 6, 7 are pushed down by the sliders 51, 51 and move down integrally to push down the electric wire 4. . The electric wire 4 is cut by the cutters 52, 52, and at the same time as the cutting, the respective ends of the electric wire 4 are pressed against the connectors 21, 21 via the electric wire pressing blades 48, 48 (see FIG. 14).

In FIG. 14, a caulking punch 49 integrated with the electric wire pressing blade 48 is adapted to caulk a pair of covering caulking portions 53 provided at the rear end of the press contact terminal 5. When the sheath crimping portions 53 are crimped, the electric wire 4 is more firmly held on the press contact terminal 5 via the insulating covering. The circuit for the continuity test is closed by the contact between the caulking punch 49 and the covering caulking parts 53, 53, and if the connection is good, the lamp 9 is turned on as described above. Such an inspection (inspection method) of the electric wire 4 constituting the sub-harness is useful for efficiently inspecting the sub-harness.

In FIG. 5, the pressure welding machines 2 and 3 are located symmetrically in the front-rear direction, and have almost the same configuration. Pressure welding machines 2, 3
Will be described in detail later (the press-welding machine 2 will be described later as a representative).

Here, the manufacturing process (manufacturing method) of the sub-harness by the press-contact device 1 will be described with reference to FIG. The description will be made only for the press machine 2 of the frame 11 on the front side (the view from the press machine 3 side. The right side in the figure is the left stage. The illustration of the band cut lid closing unit 101 is shown. Is omitted). Therefore, the connector provided at the terminal of the sub-harness is only the connector 21 here (the connector 10 with the cover).
In the case where 3 is included, the operation of a band cut lid closing unit 101 described later may be added to this example.)

First, as shown in FIG. 6A, with the connector tables 14 and 15 positioned on both sides of the frame 11, the connector holding rod 20 is set on the connector table 14 of the left stage. A desired connector 21 is arranged on the connector holding rod 20 in advance. Connector 21
Is set by, for example, automatically or manually assembling connectors 21 of various shapes to a number of various connector holding rods 20 according to the form of various sub-harnesses in a separate step. Of course, the connectors 21 may be set in the same form on a number of connector holding rods 20 of the same form. Further, a connector 103 with a cover (see FIG. 1) may be included.

Next, the lock by the fixed cylinder 17 (see FIG. 1) is released, and as shown in FIG. 6B, the connector table 14 of the left stage is moved to the servo motor 30 (FIG. 2).
1) and the drive of the timing belt 25 (see FIGS. 1 and 2), the sliding movement is performed immediately below the central press machine 2. Then, the electric wire 4 (see FIG. 5) is pressed into contact with each connector 21 on the connector table 14 on the left stage (the electric wire 4 (see FIG. 5) according to the position of the press contact terminal 5 (see FIG. 14) by driving the servomotor 30. ) Is connected). Meanwhile, the connector holding rod 20 is set on the connector table 15 on the right stage. The right stage connector table 15
As described above, various connectors 21 are arranged.

When the electric wires 4 (see FIG. 5) are pressed into contact with the various connectors 21 on the connector table 14 of the left stage while checking the continuity, the connector table 14 of the left stage is removed as shown in FIG. 6C. Then, the connector table 15 on the right stage is slid and moved directly below the center pressure welding machine 2. Then, the electric wire 4 (see FIG. 5) is pressed against the connector 21 on the connector table 15 of the right stage while checking the continuity in the same manner as described above. During this time, the connector holding rod 20 is moved from the connector table 14 of the left stage.
Is removed, and a new connector holding rod 20 is set on the connector table 14 on the left stage.

When the wire 4 (see FIG. 5) has been pressed against the connector 21 on the connector table 15 on the right stage while checking the continuity, the connector table 15 on the right stage is returned to its original position as shown in FIG. 6B. , And the connector table 14 of the left stage is moved to a position immediately below the crimping machine 2. This cycle is repeated (when the cover-equipped connector 103 is included, the band cut lid closing unit 101 is moved directly below and the cover-equipped connector 10
3). By alternately pressing the left and right connector groups, the time from connector set to connector removal is greatly reduced.

As shown in FIGS. 1 and 2, since a pair of right and left connector tables 14, 15, 37, 38 are used, separate sub-harness configurations can be obtained for the left and right connector groups. Of course. FIGS. 7A and 7B show an example of the sub-harness form. The sub-harness 56 shown in FIG.
12 (see FIGS. 1 and 2), and is manufactured by the connector tables 14, 37 (see FIG. 1) on the left stage. The sub-harness 57 shown in FIG.
12 (see FIGS. 1 and 2), and is manufactured using connector tables 15 and 38 (see FIG. 2) on the right stage (see FIGS. 1 and 2).
The electric wire 4 (see FIG. 5) is pressed against the various connectors 21 in a state where the connector 7 and the connector tables 15 and 38 are disposed immediately below the press-connecting machines 2 and 3, respectively. The sub-harnesses 56 and 57 shown in FIG.
(See FIG. 5). Cross wiring of the electric wires 4 (see FIG. 5) is performed by moving one connector table, for example, by one connector. It is of course possible to include a connector 103 with a cover).

On the other hand, as shown in FIGS. 1 and 2, the connector tables 14, 15, 3
Since the connector holding rod 20 can be detachably attached to the cassettes 7 and 38 in a cassette type, it is not necessary to change the connector arrangement, and the sub-harnesses 56 and 57 (see FIG. 7) can be manufactured quickly and reliably. Become. Also, as described above,
Since separate sub-harness configurations can be set on the left and right stages of the press-welding machines 2 and 3 and can be performed in a cassette type, sub-harness lot production (sub-harnesses of the same configuration are produced in large quantities, Rather than assembling them into a product), but set production (a method of directly producing products) becomes possible. Furthermore, high-mix low-volume production becomes possible. In addition, a plurality of sizes and shapes of connectors 21
To quickly press the wire 4 (see Fig. 5)
In the pressure welding apparatus 1 of the present embodiment, a plurality of applicators 58 (see FIG. 8) slidably holding different types of electric wire connection portions 6 (electric wire connection portions 7; see FIG. 14) (six types in this embodiment, (It is not limited to this.) The rotary type applicator itself is arranged in a rotary manner.
It has been proposed in Japanese Patent Application No. 8-189511.

Next, the pressure welding machine 2 will be described with reference to FIG. As shown in FIG. 8, the electric wire connection part 6 is fixed to the shank 60. The shank 60 is provided on the rotor 61 so as to be able to move up and down. The head 62 of the shank 60 engages with the claw 63 of the slider 51 and
Is detached with the rotation of. Rotor 61
Is fixed to the rotating shaft 64. The rotation shaft 64 is connected to a servomotor 68 via pulleys 65 and 66 and a timing belt 67. The members related to the electric wire connection portion 6 include a spring-biased movable blade guide 69.
(See FIG. 10).

Each of the applicators 58 includes the electric wire connection portions 6 and the shank 60 having different sizes and shapes, and is disposed on each of the six surfaces of the rotor 61 as shown in FIG. The applicator 58 (see FIG. 8) can be attached to and detached from the rotor 61 with bolts, and it is easy to change over to another applicator other than the six types. In addition, the measuring roller 40 shown in FIGS.
A rotary type electric wire feeder (not shown) for supplying electric wires 4 of various diameters (see FIG. 5) is arranged behind the.
The electric wire 4 (see FIG. 5) is changed according to the type and size of the press-contact terminal 5 (see FIG. 14) of the connector 21, and the electric wire connection according to the electric wire diameter is performed by a rotary applicator 58 (see FIG. 8). The section 6 (see FIG. 8) is appropriately selected.

The slider 51 in FIG. 8 is connected to a T-shaped cam 70 as shown in FIG. The cam 70 is connected to an eccentric shaft 72 of a rotating plate 71 (see FIG. 8). As shown in FIG. 8, the rotating plate 71 (see FIG. 8) is provided with a rotating shaft 74 of the speed reducing portion 73 of the servomotor 50.
It is connected to. 10, an eccentric shaft 72 is slidably engaged with a horizontal groove 75 of a cam body 70 via a slider 76, and the servo motor 50 (FIG. 8).
Rotation of the rotor 61 (see FIG. 8)
The eccentric shaft 72 moves in the horizontal groove 75 of the cam body 70, whereby the cam body 70 moves up and down integrally with the slider 51. The slider 51 moves vertically along the guide 77.

The rotation plate 71 (see FIG. 8)
11 (a) to FIG.
As shown in FIG. 11 (c), the slider 51 is lowered by rotation of 0 ° to 180 ° and located at the bottom dead center (FIG. 11C).
The slider 51 is raised by the rotation of 80 ° to 360 ° and located at the top dead center (FIG. 11A). As described above, the slider 51 and the wire connection portion 6 (see FIG. 8) move up and down integrally. The next stroke of the slider 51 is obtained by reversing the rotating plate 71 with the servo motor 50 (see FIG. 8). It goes without saying that this lifting mechanism is useful.

When the lifting mechanism is applied, it is possible to cope with various types of connectors having different wire pressing strokes (pressing heights). That is, by appropriately setting the rotation angle of the servo motor 50 (see FIG. 8), that is, the rotation angle of the rotating plate 71, the lifting stroke of the electric wire connection portion 6 (see FIG. 8) can be freely changed. Become. For example, if the rotating plate 71 is turned 90 ° in FIG. 11B and then turned over, the stroke of the slider 51, that is, the wire connecting portion 6 (see FIG. 8) is turned 180 ° (see FIG. 11B). 11 (c)). As described above, since the press-contact height can be managed by the servomotor 50 (see FIG. 8), no setup change is required, and it is possible to quickly cope with various types of connectors 21.

The rotation of the servomotor 50 (see FIG. 8) is controlled by, for example, the above-mentioned control unit (not shown), so that the electric wire connection unit 6 (see FIG. 8) is connected to the press contact terminal 5 (see FIG. 14) until the continuity test is completed. The crimped cover crimping portion 53 of

That is, even if the operation is displaced between the press-welding machines 2 and 3, it is necessary to wait for the electric wire connecting portion 6 (see FIG. 8) to rise while being in contact with the sheath caulking portions 53 and 53 (see FIG. 14). (The same applies to the crimping machine 3 side). The servo motor 50 (see FIG. 8) is controlled by the control unit (not shown), and the timing of caulking the coating caulking units 53 and 53 (see FIG. 14) is performed simultaneously with the press-contacting machines 2 and 3. Needless to say, this saves time.

In FIG. 5, vertical wire holders 80, 80 are engaged with the claws 79, 79 of the sliders 51, 51 of each of the press-connecting machines 2, 3 by grooves 81, 81, and the wire connection portions 6, 81 are engaged.

Reference numeral 5 is fixed to the frame 12 (see FIG. 5), and the electric wire receiver 84 is located immediately below the electric wire 4 when the rod 86 is in the most extended state. The electric wire retainer 80 and the electric wire receiver 84 are formed in, for example, a rod shape, a blade shape, or a block shape.

As the electric wire connecting portion 7 descends, the electric wire press 80
Are linked and integrally lowered, the wire 4 is cut by the blade portion (upper blade) 87 of the wire connecting portion 7 and the cutter (lower blade) 52. At the same time, as shown in FIG. 13, the electric wire 4 is sandwiched between the electric wire holder 80 and the electric wire receiver 84 located immediately below the electric wire 4. At the same time, the air cylinder 85 is depressurized, and the air cylinder 85 is configured to support the electric wire 4 as a weak spring body (or to depressurize the air cylinder 85 by using an air cylinder 85 having a load lower than the pressing force of the electric wire holder 80). Without
The wire holder 80 may forcibly push down the wire receiver 84 via the wire 4).

The electric wire receiver 84 can be further raised from the state shown in FIG. 12 to just below the electric wire 4 by the extension operation of the air cylinder 85. The cutter 52 (see FIG.
1), the wire retainer 80, and the wire receiver 84 fix the front and rear positions of the wire 4, and the wire 4 is supported straight.

Then, while the wire 4 is stably held between the wire retainer 80 and the wire receiver 84, the wire 4 descends integrally with the wire connecting portion 7, and the wire 4 corresponds to the connector 21 by the wire connecting portion 7. The pressure contact terminal 5 (see FIG. 12) is securely pressed. After the wire pressure welding (after the continuity test), only the wire connecting portion 7 and the wire presser 80 rise, the air cylinder 85 is completely depressurized, and the wire cylinder 84 keeps the wire 4 lowered so as not to push up the wire 4. become. When the electric wire 4 comes off from the electric wire receiver 84 by the horizontal movement of the connector table 37 (or the connector table 38), the electric wire receiver 84 is raised as shown in FIG.

Further, the cover closing means performs from the cutting of the band to the engagement and closing of the cover. Therefore, the conventional manual operation becomes unnecessary, and the sub-harness can be manufactured efficiently.

According to the second aspect of the present invention, the connector housing can be held by the band cutting portion during the second step. This prevents the connector housing from being displaced from the connector holder when the band is cut, the cover is inverted, or the cover is engaged or closed. Therefore, it is possible to reliably manufacture the sub-harness having the connector with the cover at the terminal. Further, it can be manufactured efficiently.

According to the third aspect of the present invention, the cut waste of the band can be sucked by the suction means provided in the press-contact device. There is no risk of band debris entering the connector with cover. Therefore, in addition to the above-described effects, it is possible to prevent the waste of the band from being mixed into the connector with the cover. Further, a sub-harness having a connector with a cover on a terminal can be reliably manufactured, and reliability can be improved.

The harness can be manufactured efficiently. That is, the frame has a slidable connector table, and the connector holder has the connector with the cover set thereon and is fixed to the connector table via the connector holding rod. In addition, the connector holder has a band cutting portion that slidably cuts the band, and the pressure welding machine presses one or the other end of the electric wire constituting the sub-harness to the pressure contact terminal of the connector with the cover. The pressure contact is sequentially performed on the corresponding pressure contact terminals while moving the connector table that slides the frame. The cover closing means acts to engage the banded cover with the press-fit terminal mounting portion. Therefore, the conventional manual operation becomes unnecessary, and the sub-harness can be manufactured efficiently.

According to the fifth aspect of the present invention, since the cover closing means has the first action section, the second action section and the third action section, The band cutting section can be slid in the band cutting direction by the action section. In addition, the cover can be turned upside down toward the press contact terminal mounting portion by the second action portion.

The band cutting portion is formed to have a length that is located at the set holding portion of the base member with respect to the connector housing after at least part of the band is cut, so that the connector housing can be held by the band cutting portion. The connector housing can be prevented from being displaced from the set holding portion when the band is cut, the cover is inverted, or the cover is engaged or closed. Therefore, it becomes a useful connector holder when efficiently manufacturing a sub-harness having a connector with a cover at a terminal.

According to the fourteenth aspect of the present invention,
Since the band cutting portion is disposed rotatably along the surface of the connector housing having the band, if the band cutting portion is expanded, the band cutting portion does not interfere with the band cutting portion. The connector with the cover can be set smoothly on the connector holder. Therefore, it becomes a useful connector holder when efficiently manufacturing a sub-harness having a connector with a cover at a terminal.

According to the present invention described in claim 15,
Since the band cut portion has a thickness substantially corresponding to the gap between the connector housing and the cover in an inverted state, the band can be removed only by sliding the band cut portion once. Therefore, it becomes a useful connector holder when efficiently manufacturing a sub-harness having a connector with a cover at a terminal.

According to the sixteenth aspect of the present invention,
Since the base member has a hole for guiding the cut waste of the band, it is possible to prevent the waste of the band from being mixed into the connector with cover. Therefore, the connector holder is useful for reliably manufacturing a sub-harness having a connector with a cover at the terminal. Further, reliability can be improved.
