Description

TECHNICAL FIELD The present invention relates to a ribbon cable processing device that cuts a ribbon cable at a predetermined location and attaches a pressure-18 terminal to the cut end.

"Prior Art and its Problems" As shown in FIG. 19, a ribbon cable 11 has a plurality of electric wires 12 connected to each other in parallel and in a flat state. When processing the ribbon cable 11, after cutting it to a predetermined length, the end portion 12a of each electric wire 12 is
I try to separate them from each other. Roughly speaking, a pressure contact terminal 13, for example, is attached to the end of the separated electric wire 12. The pressure contact terminal 13 is inserted into the mounting groove 14 into which the end portion 12a of each electric wire 12 is fitted, and the pressure contact terminal 13 is installed by driving the end portion 12a into the groove 14 using a pressure welding machine (not shown). It is now possible to

Conventionally, when processing the ribbon cable 11 as described above, the ribbon cable 11 is cut by a cutting machine, the cut wire ends 12a are spread out and held in parallel by an alignment means, and the wire ends 12a are pressure-welded. A device was used which was driven into the pressure contact terminal 13 depending on the machine. In addition, as the alignment means, a plurality of bins protruding in parallel at predetermined intervals are used, and the bins are attached to each wire end 12.
The end portion 12a was inserted between the holes 12a and 12b to expand the end portion 12a.

However, in the above-mentioned conventional processing device, after cutting the ribbon cable 11@, an alignment means consisting of a plurality of bins is pushed into the wire@@ portion 12a to spread it out (see 1), so that the end portion 12a is , and the position of each end 12a and the mounting of the pressure contact terminal 13 do not match the position of the groove 14, often resulting in a mounting error.

OBJECT OF THE INVENTION The object of the present invention is to spread out and align the separated ends of the ribbon cable parallel to each other so that the installation of each end or insulation displacement terminal can be accurately driven into the groove. An object of the present invention is to provide a ribbon cable processing bag M as described above.

``Structure of the Invention'' The ribbon cable processing device according to the present invention includes a pair of alignment blades that expand the electric wires located at the cutting/pressure welding point of the ribbon cable at a predetermined interval and align them in parallel, and a It is characterized by comprising a pair of clamps arranged and a cutting/pressing machine arranged further inside these clamps.

Then, by pushing a pair of alignment blades into the parts of the ribbon cable that are located at the cutting and pressure welding points, or more precisely, into the parts on both sides of the cutting and pressure welding points, the wires located between the pair of alignment blades are aligned in a specified manner. spread out at intervals and aligned in parallel. Then, by clamping the inside of each alignment blade with a pair of clamps, the alignment state of the electric wires is fixed. In this state, the ribbon cable is cut using a cutting/pressure welding machine and pressure Wi is applied, whereby a pressure contact terminal can be attached to the cut end of the ribbon cable.

In this case, since the alignment of the wire ends is fixed by the clamp as described above, the pressure contact terminal can be accurately driven into the groove without shifting the wire ends. This reduces the number of defective products and improves yield.

It is designed to move roughly up and down from the state where it is supported. Therefore, while the upper movable block 60 is lowered to some extent, the air cylinder 72 is activated to further lower the upper blade 68, and at the same time, the air cylinder 61 is activated to raise the lower blade 69 together with the lower movable block 60. As a result, the upper blade 68 and the lower blade 69 come into sliding contact to perform cutting.

The length measuring device 108 has a rear stopper 109 and a shock absorber 110, and can be fixed at any location on the rail 91 by a lock lever 111. Roughly speaking, a beam mitt switch 112 is attached to the length measuring device 108 to detect when the slider 92 touches the rear stopper 109 and send a signal to the drive device. A scale 113 is attached to the 91, and a length measuring device 10 is attached according to the desired length of the ribbon cable.
The position of 8 is determined and measurement is made easily.

The first movement is performed by moving the movable block 123 by the air cylinder 122 and moving the lot 121 in the axial direction accordingly. Furthermore, an air cylinder 125 is attached to the movable block 123 via a housing 124, and when the air cylinder (25) is operated, the rod 121 is roughly moved in the axial direction even with respect to the movable block 123. On the other hand, the clamp table 94 is moved in the second operation.
A lock-up device N126 is slidably attached to the rod 121. Further, an air cylinder 127 is connected to the slider 92, and the slider 92 moves along the rail 91 by the operation of the air cylinder 127.

As a result, the clamp stand 94 mounted on the slider 92 via the auxiliary rail 93 is moved, and the rear clamp I is moved for the +H operation. At this time, the lock-up device 126 is unlocked and slides along the lot 121. Then, when operating the air cylinder 125 mentioned above, the lock-up device +26! When locked, the clamp base 94 moves on the auxiliary rail 93 as the O-rad 121 moves in the axial direction, thereby causing the rear clamp I to move in the second operation. In this way, the movement of the center clamp Gδ and the dipping clamp (2) in the second operation is an integral movement by the opening and closing of the zero pickup device 126. Therefore, it is possible to accurately determine the timing and amount of movement of both. Incidentally, as the lockup device 126, a known device using, for example, an 0-link up ring can be used.

As shown in FIG. 12, the rear clamp (2) grips the tip of the ribbon cable 11, and the front clamp (C) releases the ribbon cable 11 and returns to its original position.

The rear clamp (2) moves in the direction of the arrow in the figure and pulls out the ribbon cable 11 by a predetermined length. This length can be freely adjusted using the length measuring device 108 shown in FIG. As the rear clamp (2) moves, the slitter A moves up and down as shown by the arrow C in the figure, separating the electric wires 12 at the portions corresponding to the cutting and pressure-welding points of the ribbon cable 11 from each other.

As shown in FIG. 13, when the movement of the rear clamp (2) is completed, at least the space between the first alignment blade 8 and the second alignment blade H becomes a part where the electric wire 12 is separated by the slitter A. There is. In this state, push the first alignment blade B into the ribbon cable 11 and at the same time press the front clamp C on the inside of it.

The Novon cable 11 will not become sagging, bent, or cut due to excessive tension.

As shown in FIG. 15, when the cut ends of the ribbon cable 11 come to the positions of the first pressure welding machine and the second pressure welding machine F, the movement of each clamp C, G, and T is stopped. At this time, the expanded electric wires 12 of the ribbon cable 11 are fixed in alignment by the front clamp C and the center clamp G, so that the ends 12a of each electric wire 12 or the pressure contact terminals 13 are installed in the grooves 14 accurately. He was defeated once.

In the above embodiment, only one of the pressure welding machines and F is used, and the cutting machine E is also equipped with a stripping blade, so that one end of the ribbon cable 11 has a pressure of 1! Attach the terminal,
The other end may be left uncoated.

"Effects of the Invention" As explained above, according to the present invention, a pair of alignment blades is inserted into the portion corresponding to the cutting/pressure welding point of the ribbon cable, and each wire of the ribbon cable is spread out and parallel to each other. Since the wires are arranged in the same direction and the inside of each of the roughly aligned blades is held by a pair of clamps, it is possible to fix the expanded alignment state of the electric wires. Since the wires are cut in the above condition and the cut ends are driven into the insulation displacement terminals, the ends of each wire and the grooves are not misaligned when installing the insulation displacement terminals. It is possible to reduce mistakes and improve yield.
