Description

DETAILED DESCRIPTION OF THE INVENTION Romitsu Doowaka Natsuhada■ The present invention relates to an improvement in a method for continuous crimping of electric wires and terminals during the production of wire harnesses.

A method and an apparatus for successively crimping and connecting a plurality of electric wires and terminals are known, for example, as disclosed in Japanese Patent Publication No. 12064/1983. This is an example of a base for installing various devices.A lamp chain for carrying electric wires is attached to the edge of the base with clamps for gripping the electric wires attached at approximately equal intervals. place the equipment,
After straightening and stripping the wire, a desired terminal is continuously crimped with a desired device on the end of the wire that is intermittently transferred.

Each crimping device is equipped with a pair of rams and a press stand that face each other in a vertically movable manner, and the electric wire floating between the rams and the press stand is sandwiched between the ram and the press stand from above and below to form a terminal. It was intended to be crimped.

In the conventional technology, the electric wire is stopped floating between the open ram and the press stand, and the ram presses down the wire while pressing down on the pair of crimping pieces of the terminal. Since the terminals of the electric wires are guided in between and crimped and connected, there is a problem that the terminals of the electric wires are bent and a process such as correcting the posture is required when inserting them into the connector housing, and the terminals are easily crimped incorrectly.

An object of the present invention is to solve these problems and provide a method for continuously crimping terminals without bending the end portion of the wire or crimping errors.

In order to achieve the above-mentioned problem of increasing the number of wires, the present invention provides a terminal crimping device that includes a pair of rams and a press stand, and intermittently connects a plurality of electric wires held in parallel at predetermined intervals facing each other. In the method of crimping a terminal by moving the terminal, the terminal crimping device and one of the plurality of electric wires is provided so as to be able to move toward and away from the other or to move up and down, and the ram is lowered with the terminal placed on the press stand. The method is characterized in that the plurality of electric wires are intermittently moved after the terminals are crimped.

Further, as described in claim 2, the terminal crimping device is provided so as to be movable up and down, and the pair of rams and the press stand are placed on standby in an open state, and the plurality of electric wires are intermittently moved through the open space. By crimping the terminal when the desired wire reaches the terminal crimping device, the device and process for the crimping method can be most simplified.

In the present invention, the terminal is crimped with the wire placed on the press stand of the terminal crimping device, that is, between the pair of crimping pieces of the terminal. Electric wires with terminals of constant quality can be obtained without bending or crimping errors.

In addition, the terminal crimping device and the plurality of electric wires held in parallel facing the device are installed so that one of them can be moved toward and away from the other or can be moved up and down, so there is no problem in intermittent movement of the electric wires. , can be passed freely.

At that time, if the terminal crimping device is movable up and down and moves the plurality of electric wires intermittently through the open space between the ram and the press stand, the terminal crimping device is raised and the wires are moved to the press stand. After crimping, it is sufficient to simply lower the device, the mechanism of the device is simple, the number of steps for crimping the terminals is minimal, and quick crimping is possible.

Hereinafter, the steps from producing a fixed-length electric wire to fitting it into a case and the operation of each device will be explained.

[Production process of fixed length electric wire]

First, FIGS. 3a and 4a show that the tip of the long electric wire W pulled out from the reel station A (FIG. 1) is placed on the wire temporary holding plate 10 by the wire feeding guide ring 33.
The wire is stretched into a U-shape by the stretching head 9 through the wire check roll 34 and the wire insertion tube 35, and is cut by the wire cutting blade 14 of the U-turn turning head 8, with both ends adjacent to the wire clamping rod 3. It shows the state where it is held between two wire clamps 4 (hereinafter referred to as the "end point").
.

The length of the U-shaped wire W1 that has been stretched and cut is approximately 2, and its total length is approximately 2.

After cutting, the wire cutting blade 14 is raised by the operation of the cylinder 21 as shown in FIGS. The tip of the long electric wire W left behind is bent into a U-shape, and the bent end is pushed and held between the electric wire insertion tube 35 and a pair of adjacent electric wire locking plates 36. After clamping, the wire temporary holding plate 10 moves one pitch (distance between adjacent wire clamps 4 of the wire clamp rod 3) in the direction of the arrow in FIG.

In this way, by stretching and cutting the long electric wire W, a fixed length electric wire W is obtained.
After producing I, the tip of the remaining long electric wire W is bent into a U-shape and prepared for the next process of producing a fixed length electric wire by sequentially drawing and cutting. In FIG. 1, a wire temporary holding plate 10 (see FIG. 4) indicated by a two-dot chain line holds a plurality of long wires W bent in a U-shape, such as a wire insertion tube 35 and a wire locking plate 36. Indicates the state held in (hereinafter referred to as "
"Starting point". ).

Figures 3C and 4C show the starting state of the wire drawing process. In this state, the transfer head 1 is moved by the operation of the cylinder 41.
1 moves onto the wire locking plate 36 as shown by the arrow, and the pair of wire clamp plates 37 descend to grip the U-shaped bent end of the long electric wire W and its opposing portion, and After rising and retreating, it is moved and clamped by the wire clamp 4 (FIG. 4d).

Next, as shown in FIGS. 3 d and 4 d, the wire fixing plate 42 a of the wire fixing head 42 is lowered to clamp and fix the U-shaped bent end to the wire clamp 4 . At the same time, the enlarging head 9 approaches the U-shaped bent portion by rotation of the length measuring motor 28 (FIG. 1). At this time, the wire hooking pin 24
is in the lowered position, the front sides of the upper and lower bin guide plates 23.23 are open, and the U-shaped bent portion enters between the plates 23.23. Therefore, the wire hooking pin 24 is attached to the cylinder 26.
is raised to close the open portion.

Next, as shown in FIGS. 3e and 4e, the enlarging head 9 is moved back by half (L) of the required wire length by the reverse operation. Then, the wire hooking pin 24 is lowered to release its engagement with the wire, and the wire fixing plate 42 is raised and returned to its original position.

Finally, as shown in Fig. 3f, the swinging U-turn head 8 is lowered by the actuation of the cylinder 18 to the side of the long electric wire W that has been U-turned, and after the electric wire is clamped by the electric wire clamp plate 13, the electric wire is cut. When cut by the blade 14, it returns to the "end point" as shown in FIG. 3a.

Next, a U-shaped bent portion is sequentially formed on the long electric wire W,
It is transferred to the position indicated by the two-dot chain line in FIG. 1 and clamped by the newly supplied wire clamping rod 3.

As a result, a desired fixed length electric wire W+ having a total length of about 2L is produced.

Below, the "starting point" of Figure 3 a - f and Figure 4 a - e
By repeating "end point" from "end point" repeatedly, as shown in FIG. A primary intermediate product P1 of harness is obtained.

In the above-mentioned manufacturing process of the fixed-length electric wire, the wire clamping rod 3 with the electric wire clamps 4 arranged in parallel is used as a clamping and fixing means for both ends of the fixed-length electric wire Wl. It is possible to use an endless chain as disclosed in the above publication, in which electric wire grippers (consisting of a pair of grippers that can be opened and closed) are provided at a predetermined pitch. In addition, the process of bending the tip of the long electric wire W1 into a U-shape, the stretching process, the cutting process, and their processing positions are separated, and the transfer head 11 is omitted to temporarily hold the electric wire at the U-shaped bent part. It will be easily understood that the step of transferring from FiIO to the wire clamping rod 3 may be omitted.

[Wire stripping and straightening process]

The primary intermediate product PI is sequentially conveyed one pitch at a time in the direction of the arrow on the conveyor table 1' as shown in FIGS. After that, the wire is stripped using a wire stripping device.

[Terminal crimping process]

A plurality of terminal crimping devices E1, Ez, etc. shown in FIG.
... are in the lowered position with the ram 46 and press table 47 open, as described above (FIGS. 5a and 5b). Through this open space, the terminal portions of the plurality of fixed length electric wires W fixed to the clamp rod 3 are intermittently moved one pitch at a time. Each of the devices E+, Ez, . . . is provided with a chain of terminals 48 having different shapes and sizes.

Therefore, during the above-mentioned intermittent movement, the desired terminals 48 are sequentially and continuously crimped onto both ends of the predetermined length electric wire W1 using devices selected from the devices EI, E2, . . . I can do it. In FIGS. 11A and 11C, one end of the length electric wire designated by the symbol Wl' is connected to a terminal 48. by device E+. shows the crimped state. The crimping is done using device E as shown in Figure 5a and b.
1 is raised by the cylinder 44. Next, press table 47
This is done using a known mechanism in which the wire crimping portion 48a of the terminal 48 is placed on the holder and the ram 46 is lowered. After crimping, the device E1 is lowered in the opposite direction to return to the state shown in FIG. 5a.

Continuous crimping of terminals can also be achieved by providing one of the wire clamping rod 3 and the crimping devices El, EX, .

[Composite crimping process for terminals]

Composite crimping, in which two or more electric wires are crimped and connected to one terminal, is achieved in parallel with the crimping process.

That is, as shown in FIG. 11, a combination head 50 that can be raised and lowered is located between the stripping device and the terminal crimping device E, and its wire clamp plate 51 is designated by reference numeral 4. It is located directly above the wire clamp indicated by . Therefore, the wire clamp plate 51 descends to grip the end portion of the fixed-length wire W, // and then rises to move the wire clamp rod 3 one pitch.
Lower and raise the electric wire W in the opposite manner to the above, and as shown in FIG.
Stack it on /// and hold it.

Figure 12 shows a fixed length electric wire W, / with a wire clamp 4□.
A composite sandwiching state of / and W, /// is shown. Therefore, when the wire clamp 42 reaches the desired terminal crimping device (El, E2, . . .) from the intermittent movement of the wire clamp rod 3, it is sufficient to perform the crimping connection in the same manner as in the normal crimping process.

In addition, the above-mentioned composite clamping for composite crimping of electric wires (12th
), by moving the composite head 50 parallel to the wire clamp 3, a desired fixed length wire Wl can be obtained.
It can be done more easily and in a variety of forms.

Thus, as shown in FIG. 11d, a secondary intermediate product P2 is created in which a plurality of wires with terminals (standard length wires) Wl including composite crimping are held at both ends by the wire clamp 4 of the wire clamp rod 3. can get.

[Case fitting process]

The secondary intermediate products P2 are collectively transferred to a setting table 52 on which a plurality of connector housings Iyz, 13 and ■4 are arranged as shown in FIG.

Here, the moving plate 64 is moved along the guide rail 66 by the operation of the step motor 68, as shown in FIG. 6a, and positioned above the desired wire clamp 4.

Next, by operating the cylinder 65, the holder support plate 61, ie, the wire clamp plate 56, is lowered to grip the fixed length electric wire W (FIG. 6b), and then the terminal gripping claw 54 and the wire gripping claw 55 are lowered, respectively. Wire crimping portion 48 of terminal 48
Sandwich a and the electric isw + from both sides (Fig. 6C)
.

At this time, as shown in FIGS. 7a and 7b, the terminal gripping claws 54
, 54 is lowered by the operation of the lift cylinder 63 to push down the terminal 48, and cooperates with the protrusions 54a and 55a to arrange the terminal 48 in a substantially horizontal constant position.

Subsequently, the terminal gripping claw 54 to the wire clamp plate 56 are raised in the reverse operation to remove the wire Wl from the wire clamp 4, and if necessary, the movable plate 64 is moved laterally in the same manner as above to remove the terminal 48. The tip end is made to face the terminal accommodating chamber 73 (FIG. 10) of a desired housing selected from the plurality of connector housings I, I2, . . . (6th
Figure d).

Next, as shown in FIGS. 6e and 6f, the head holder 59 is advanced toward the housing and the electrical contact portion 48b of the terminal 48 is inserted into the terminal accommodating chamber 73, and then the terminal gripping claw 54 and the wire gripping claw 55 Open and raise.

Subsequently, as shown in FIG. 6g, the head holder 59 is further advanced while holding the wire W1 with the wire clamp plate 56.
The terminal 48 is inserted into the terminal accommodating chamber 73 as shown in FIG. As a result, the terminal 48 is engaged with and locked with the locking arm 74.

By repeating the above operations, a desired fixed length electric wire W is obtained.

Connect the terminal 48 of the terminal 48 to the desired connector housing (I+).

■2...) can be inserted into the predetermined terminal accommodation chamber 73.

[Terminal alignment mechanism]

When inserting the terminal 48 into the terminal accommodating chamber 73 in FIGS. 6d and 6e, it suffices if the axes N and N' of both are parallel as shown in FIG. If the axis N of 48 is tilted, smooth insertion will not be possible.

Therefore, the sensor 71 detects the error between the distance 2' between the sensor 71 and the tip of the terminal 48 and the set value 1, and if there is no error, move it by the distance and insert it as it is, and the error (±Δ2) If there is, use the moving plate 64! Correct by moving ±Δl.

Since this set value i varies depending on the shape and size of the terminal, it is stored in advance in the control device G for each type. As the sensor 71, a known sensor including a light emitting element and a light receiving element including a phototransistor, for example, can be used. Further, instead of distances z and z', reflection angles may be measured and compared.

In addition, when aligning the centers, it is not necessary to make the axis N of the terminal parallel to N'; insertion is possible as long as the center 0 of the tip of the terminal 48 coincides with the axis N' of the terminal receiving chamber 73. It is.

[Terminal insertion check mechanism]

Although the case fitting is completed by inserting the terminal 48 shown in FIG. 6g, it is preferable to check for incomplete insertion.

Therefore, as shown in FIG. 9, the mounting head 58 is swung (backswinged) in the direction of the arrow to apply a predetermined tension to the electric wire W. This makes it possible to determine whether there is incomplete insertion. As described above, instead of swinging, the wire clamp 56, ie, the head holder 59, may be moved backward.

FIG. 13 shows a state in which the fixed-length wire W5 group fitted in the case is removed from the wire clamp rod 3. And each connector housing 1. ,1. ．． Tape Tr, Tz at appropriate locations of the group of wires W7 of fixed length arranged in a U-shape between I and 14.
, Tx .

As explained above, according to the method of the present invention, there is no bending of the wire ends or crimping errors when crimping terminals, and the terminals can be crimped quickly and continuously while simplifying the equipment. This contributes to improved wire productivity.
