BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coaxial cable processing apparatus for processing a coaxial cable terminal.

[0002]

2. Description of the Related Art Generally, in order to connect a terminal of a coaxial cable to a connector terminal or the like, the terminal of the cable must be processed. FIG. 5A illustrates an example of the state of the coaxial cable 10 immediately before the processing is performed. In this case, the insulating sheath 11 is about 4.5 [m] from the end face.
m], the braided conductor 12 located between the insulating outer skin 11 and the insulating inner skin 13 made of foam is also slightly cut off from the end face, and 3 to 4 [mm] is exposed. Although not shown here, a central conductor 14 of a single line is inserted through the central axis of the insulating inner skin 13.

[0003] From such a terminal state, the exposed braided conductor 12 is turned around the root portion thereof toward the insulating outer cover 11 and then turned over.
5 is cut away from the vicinity of the base, leaving the inner central conductor 14, so that a connector terminal or the like can be connected to the end of the coaxial cable 10 as shown in FIG. 5 (2). .

2 are arranged. The turntable 22 can be moved by the single-axis robot 23 along the axial direction of the coaxial cable 10 as shown by an arrow VIa in the figure. As shown in FIG. Is installed.

[0006] A vacuum nozzle 27 also serving as a knitting sleeve and a tip positioning block 26 are mounted on a nozzle protruding cylinder 25 mounted on a nozzle vertical cylinder 24 so as to face the coaxial cable 10. Is established.

The nozzle vertical cylinder 24 is indicated by an arrow VIb in the drawing.
As shown in the figure, the nozzle protruding cylinder 25 can be moved in the axial direction of the coaxial cable 10 as shown by an arrow VIc in FIG. The sucked vacuum nozzle 27 can be brought into contact with the coaxial cable 10 as an object and sucked.

FIG. 7 mainly shows various processing tools for the coaxial cable 10 mounted on the turntable 22. A pair of knitting wire raising cylinders 28, 28, which are arranged 180 ° opposite each other, are shown. A total of six cylinders consisting of the knitted wire stripping cylinders 29 and 29 and the endothelial cutting cylinders 30 and 30 are arranged radially so that the central angle is 60 °.

From the state of the coaxial cable 10 shown in FIG. 5A, the braided wire raising cylinders 28, 28 are exposed at the root portions of the braided conductor 12 by braided wire raising claws 28a, 28a provided at the ends of the cylinders. Is temporarily clamped to deform the braided conductor 12 so as to float from the insulating inner skin 13.

[0010] The knitting wire stripping cylinders 29, 29 are provided with stripping claws 29a, provided at the tips of the braided conductors 12 at the tip ends of the braided conductors 12 in a state of being floated from the insulating inner skin 13 by the operation of the knitting wire raising cylinders 28, 28, respectively. 29a, the coaxial cable 10 is peeled off on the insulating sheath 11 on the opposite side to the terminal.

The endothelial cutting cylinders 30, 30 are operated by the above-described braided wire stripping cylinders 29, 29 so that the braided conductor 1
The exposed insulative endothelium 13 of the coaxial cable 10 with the stripped 2 is cut into the endothelial cutting claw 30 provided at the tip of each cylinder.
The cut is made by a and 30a leaving the center conductor 14.

However, the turntable 22 is driven to rotate by a table rotation motor 31 as shown by an arrow VII in the drawing, and the desired cylinders 28, 28 to 3 are rotated.
0, 30 are controlled to be at desired positions on a plane perpendicular to the axis of the coaxial cable 10, and the entire turntable 22 is coaxial cable 1 as shown in FIG.
The cylinder can be moved along the zero axis direction, and the chuck operation of each cylinder uses air pressure as an operation source.

Next, the actual processing of the coaxial cable 10 by the processing apparatus will be described. First, FIG. 8 (1)
5A, after the coaxial cable 10 in the state shown in FIG. 5A is securely fixed at a predetermined position by the feeder clamp 21, the knitting wire raising claws 28a of the turntable 22 are used by the knitting wire raising cylinders 28, 28. , 28a are temporarily clamped at the exposed base portion of the braided conductor 12, thereby deforming the braided conductor 12 so that the braided conductor 12 floats from the insulating inner skin 13.

This operation is repeated two more times while rotating the turntable 22 by the table rotation motor 31 and shifting the central angle by 60 ° as shown in FIG.
By a total of three clampings, the braided conductor 12 floats from the insulating inner skin 13 over the entire periphery from the exposed root portion.

Thereafter, in step 2 of FIG. 8 (2), the braided conductor 12 that is floating over the entire circumference from the insulating inner skin 13 of the coaxial cable 10 also serves as a sleeve for raising a braid. By pressing the end of the vacuum nozzle 27 in contact with the vacuum nozzle 27 and pressing it toward the root portion as shown by arrow VIIIb in FIG.

Next, in step 3 of FIG. 8 (3), the tip of the coaxial cable 10 is guided by the vacuum nozzle 27, and the knitting wire stripping cylinders 29, 29 of the turntable 22 are operated to turn the stripping claws 29a, 29a. 2
9a is brought into contact with each tip as shown by arrow VIIIc in the figure.

At the tips of the stripping claws 29a, 29a, semi-circular cutouts slightly larger than the diameter of the insulating endothelium 13 are formed, and these notches are applied as shown by arrows VIIIc in the figure. By making contact, the insulating inner skin 13 can be inserted, but a circular hole is formed in the braided conductor 12 which is in a state of being raised around the entire periphery thereof, so as to interfere with the braided conductor.

Accordingly, the single-axis robot 23 adjusts the axial position of the coaxial cable 10 with the tip of the stripping claws 29a and 29a kept in contact with each other, and the arrow VIIId in FIG.
When the braided conductor 12 in the raised state is slid as shown in FIG.

Thereafter, in step 4 of FIG. 8 (4), the endothelial cutting cylinders 30, 30 are operated in place of the knitting wire stripping cylinders 29, 29, and the coaxial cable 10 is stripped as shown by arrow VIIIe in the figure. The insulating endothelium 13 is cut by the endothelial cutting claws 30a, 30a at a position slightly closer to the end of the coaxial cable 10 than the base position of the returned braided conductor 12.

At this time, semi-circular cutouts slightly larger than the diameter of the center conductor 14 are formed at both ends of the endothelial cutting claws 30a, 30a. Although 13 is cut, the center conductor 14 inserted through the central shaft portion is not cut.

At this time, the vacuum nozzle 27
When the turntable 22 and the vacuum nozzle 27 are slid and moved as shown by the arrow VIIIf in the drawing while sucking the position where the coaxial cable 10 abuts, the cut insulating sheath 13 is moved to the center conductor 14. 5 and is separated from the coaxial cable 10 while being sucked by the vacuum nozzle 27. As a result, the processing of the terminal of the coaxial cable 10 is completed as shown in FIG.

[0022]

In the above-described processing apparatus, as shown in FIG.
Each type of cylinder must be mounted in pairs, and a table rotation motor 31 for rotating the turntable 22 and a single-axis robot 23 for sliding movement are required. It becomes very complicated.

In addition, together with this, one type of cylinder,
For example, paying attention to the knitting wire raising cylinders 28, 28, it is inevitable to form a pair having a central angle of 180 ° due to the relationship with the other cylinders, and therefore, as shown in FIG. The knitting-raising nails 28a are provided over the entire circumference of the ten.
In order to clamp 28a, it is necessary to perform a total of three clamping operations while rotating the turntable 22 at a central angle of, for example, 60 °, which increases the time required for the operation. Was.

The present invention has been made in view of the above circumstances, and has as its object to coaxial cable processing apparatus capable of simplifying the structure as much as possible and reducing the time required for processing. Is to provide.
