This invention relates to a device for primary processing both ends of a coaxial ribbon cable so that a connector can be connected thereto.

[Conventional technology]

The above-mentioned coaxial ribbon cable has a signal line, a drain line, and a shield line intertwined within the jacket, and it is necessary to sort them before connecting a connector. In the past, this work was done exclusively by hand, that is, removing the outer sheath from the ends and then blowing and bending the delicate shield wires to separate the signal wires and drain wires. .

[Problem that the invention seeks to solve]

When the above-mentioned work is performed manually, efficiency is inevitably low, costs are high, and processing uniformity tends to be lacking.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coaxial ribbon cable end processing device that enables the above operations to be performed mechanically, thereby improving production efficiency and reducing operating costs.

[Means for solving problems]

In the present invention, a clamp section 1 consisting of an upper press that is moved up and down by a clamp cylinder and a lower press that receives the upper press is installed on a slide base that is moved by the action of a rodless cylinder,
The outer cover is composed of a stationary claw and a corresponding movable claw, and the movable claw opens and closes by rotating under the action of a cylinder, and is movable toward and away from the clamp part. Strip part 2
is installed on the slide base, and a cutting part including a plurality of upper blades for cutting a cutting line into the ribbon cable and a plurality of lower blades opposing the cutting part is attached to the clamp part 1.
An air blowing unit 4 is attached to and fixed on a stationary base on which the rodless cylinder is installed, and further has an air blowing part 4 on the stationary base that moves vertically and horizontally by the action of the two cylinders. The above problem was solved by the installed coaxial ribbon cable terminal processing equipment.

[Effect]

After the ribbon cable is set in place, the cable main body is clamped in the clamp part 1. Further, the tip end of the ribbon cable is clamped by the jacket strip part 2. With the above two places clamped, the clamp part 1 and jacket strip part 2 move to guide the ribbon cable to the notch 3 and pass through it to make one or several score lines (6th Figure B). Alternatively, move the notch portion 3 to make a score line. The jacket stripping part 2 is moved to the score line to be stripped and reclamped there. Then, by retracting the jacket stripping section 2 while clamped, the jacket is stripped (FIG. 6C).
When the air blowing section 4 starts the blowing operation, the tips of the delicate shield wires are blown downward from their roots (FIG. 6D). In addition, due to the difference in resistance to blowing, the drain wire curves slightly upward.

The clamp cylinder 25 is fixed on the strip base 27 via a bracket 30, and its rod is connected via a joint 31 to a clamp piece 32. The clamp piece 32 is supported by a shaft 33 and is rotatable on a clamp piece 34 fixed on the clamp base 27, and has a movable claw 23 attached to its tip. The stationary claw 24 is attached to the upper end of the clamp piece 34. Thus, when the clamp cylinder 25 operates, the clamp piece 32 rotates, thereby opening and closing the clamp portion consisting of the movable claw 23 and the stationary claw 24. Also,
The motor 26 is fixed on the slide base 12, and moves the rack 35 back and forth in accordance with its operation. The tip of the rack 35 is attached to a block 36 fixed on the strip base 27. Therefore, with the movement of the rack 35,
The strip part base 27 on which the clamp part and the clamp cylinder 25 are installed is supported by the LM guide 28 and moves on the guide rail 29. 37 is a stopper for regulating the retracted position of the strip base 27, and 38 is a sensor for regulating the retracted position of the rack 35.

Next, an example of the configuration of the notch 3 will be described. 39,
Numeral 40 denotes pillars erected on the front and rear of the stationary base 21, to which upper blade bases 41, 42 and lower blade bases 43, 44 are passed. The pillar 39, upper blade base 41, and lower blade base 43 are sandwiched inside the upper press 6 and lower press 7, and the wheels 18 are in contact with both sides of the upper blade base 41. In addition, a pillar 40, an upper blade base 42, a lower blade base 4
4 is located on the outer surface of the upper press 6 and lower press 7, and the upper blade base 42 is in contact with the wheel 18. Each upper blade base 41, 42 and lower blade base 43, 44 has an upper blade holder 45,
46, the upper blade 4 via the lower blade holders 47 and 48
9, 50 and lower blades 51, 52 are attached. In the illustrated embodiment, three upper blades 50 and three lower blades 52 are provided, so that the ribbon cable 13 has four cutting edges as shown in FIG. 6B.
The book's score lines a to d will be inserted. The upper blades 49, 50 and the lower blades 51, 52 are configured so that their opening degrees can be adjusted. That is, the upper blade holder 4
5, 46 and the lower blade holders 47, 48 are both attached to the shaft 5.
3 as a fulcrum, and the upper blade base 4
1 and 42 and the lower blade bases 43 and 44, adjustment pieces 54 having sloped tips are attached to the upper blade holder 4.
5, 46 and the lower blade holders 47, 48 are placed between them. The adjustment piece 54 can be moved back and forth by rotating the micro head 55, and when it is moved forward, its slope will touch the bottom of each of the diagonally cut upper blade holders 45, 46 and lower blade holders 47, 48. It enters the area and acts to push it up. Therefore, by adjusting the degree of advancement of the front and rear adjustment pieces 54, the upper blade holders 45, 46 and the lower blade holders 47, 48 can be rotated, thereby adjusting the opening degree of both the upper and lower blades. 40a is a cable guide attached to the pillar 40.

As shown in FIGS. 3 and 4, the air blow section 4 includes a blow piece 56 having a jet hole at its tip, a twin rod cylinder 57 that moves the blow piece 56 up and down, and a twin rod cylinder 57 that moves the blow piece 56 back and forth. It is composed of a twin rod cylinder 58 that moves. The blow piece 56 has a blow piece 59 connected to the compressor and a joint 60.
and is inserted into a vertically elongated hole 61 provided in the pillar 40 of the notch 3. Further, the twin rod cylinder 58 is fixed to the outer surface of the pillar 39, and the twin rod cylinder 57 is fixed to the rod of the twin rod cylinder 58 via a cylinder holder 57a. Therefore,
When the twin rod cylinder 58 operates, the blow piece 56 moves back and forth, and when the twin rod cylinder 57 operates, the blow piece 56 moves up and down. A dust collection port 62 is opened below the blow position and communicates with a dust collection pipe 63 connected to a dust suction device. Reference numeral 64 denotes a chute for collecting the processed ribbon cable 13, which is installed so as to be inclined downward from the stationary base 21 via a bracket 65. Ribbon cable 13
A mechanism for stopping the tip of the ribbon cable 13 in a fixed position when it is supplied from the cable guide 19 is shown in FIGS. 3 and 5. That is, 66 is a seesaw that rotates around a shaft 67,
Long holes 68 and 69 are formed at both ends. 70 is a cylinder, and the pin 71 attached to the rod is
It is engaged with the elongated hole 68. In addition, 72 is a stopper, and a pin 73 attached to the bottom of the stopper is inserted into the elongated hole 6.
9 is engaged. The stopper 72 is movable up and down within the lower press 7. Therefore, when the cylinder 70 operates, the elongated hole 68 of the seesaw 66
side is pressed down, the elongated hole 69 side rotates upward, and the stopper 72 is raised. As a result, the tip of the ribbon cable 13 comes into contact with the stopper 72, and positioning is performed.

To explain the operation of the embodiment with the above configuration, first, the ribbon cable 13 to be processed is manually or mechanically fed onto the cable guide 19 and pushed to a fixed position regulated by the stopper 72. At this time, the upper press 6 is raised by the action of the clamp cylinder 5, and the movable claw 23 is rotated upward by the action of the clamp cylinder 25.
The clamp part is in an open state. and,
When the ribbon cable 13 is supplied, the upper press 6
descends and strongly presses the ribbon cable 13 between it and the lower press 7, firmly holding down its center side.
Further, the movable claw 23 is also closed, and the tip of the ribbon cable 13 is held between it and the stationary claw 24. When the rodless cylinder 20 operates in that state,
The clamp part 1 on the slide base 12 moves to the left in FIG. 2, and the ribbon cable 13 passes between the upper blades 49, 50 and the lower blades 51, 52, so that the outer sheath is in the position where it is to be stripped. Score lines a to d are made (FIG. 6B). Of the four score lines a to d, the position to be finally stripped is score line a, but in this device, stripping is performed starting from score line b. After being cut, the ribbon cable 13 moves to the blow position shown in phantom lines in FIG. There, the movable claw 2
3 opens and becomes unclamped, motor 2
After the clamp portion advances to the position of the cut line b by the action of step 6, it is clamped at that position again. and,
When the motor 26 operates in the opposite direction, the rack 3
5 and block 36, the strip base 27 is pulled, and the jacket strip 2 resting thereon is moved to the right in FIG.
As a result, the outer cover is peeled off from the position of the cut line b, and the signal line A, the drain line B, and the shield line C are exposed (FIG. 6C). Therefore, by reciprocating the twin rod cylinder 58,
The spout of the blow piece 56 reciprocates across the tip of the ribbon cable 13 from which the sheath has been stripped off. When air is blown from the nozzle, only the delicate shield wires are blown and bent from their roots.
It is separated from the other two lines (Fig. 6D). This blowing operation is preferably performed in two steps. That is, the first blow is performed intermittently, and the second time is a continuous blow. The reason for doing this is to increase the chances of blow bending, as air pressure is large at the beginning of the blow and is particularly effective for blow bending, and to prevent the wire from waving in the blow direction by continuing to blow continuously. This is to prevent this. Wire debris generated during the blowing operation is sucked through the dust collection port 62.

〔Effect of the invention〕

The present invention is as described above, and has the effect that it is possible to mechanically and continuously perform the work of sorting the signal wire, drain wire, and shield wire of a coaxial ribbon cable, thereby realizing work efficiency and cost reduction. There is.
