BACKGROUND OF THE INVENTION
The present invention relates to a coaxial cable processing apparatus for processing a terminal of a coaxial cable.
[0002]
[Prior art]
Generally, in order to connect a coaxial cable end to a connector terminal or the like, the cable end must be processed. FIG. 5 (1) illustrates the state of the coaxial cable 10 immediately before the processing, and here, the insulating outer shell 11 is cut from the end face by about 4.5 [mm], and the insulating outer shell 11 and the foamed body are removed. Similarly, the braided conductor 12 positioned between the insulating endothelium 13 is slightly cut off from the end face, and 3 to 4 [mm] is exposed. Although not shown here, a central conductor 14 made of a single wire is inserted through the central axis portion of the insulating endothelium 13.
[0003]
From such a state of the terminal, the exposed braided conductor 12 is folded back and inverted toward the insulating skin 11 around the root portion, and then the exposed insulating endothelium 13 is moved from the vicinity of the root to the inner central conductor. By cutting away 14, a connector terminal or the like can be connected to the end of the coaxial cable 10 as shown in FIG. 5 (2).
[0004]
6 and 7 show a schematic configuration of the coaxial cable processing apparatus 20 that performs the processing as described above. FIG. 6 shows the configuration of the entire apparatus viewed from the side, and FIG. A detailed configuration around the table is shown.
[0005]
In FIG. 6, the unprocessed coaxial cable 10 is held and fixed to a feeder clamp 21, and a flat plate ring-shaped turntable 22 is coaxially disposed at a terminal portion where the processing is performed. The turntable 22 can be moved along the axial direction of the coaxial cable 10 as indicated by an arrow VIa in the drawing by the single-axis robot 23. Various processing tools for the coaxial cable 10 as shown in FIG. Is placed.
[0006]
Further, a vacuum nozzle 27 that also serves as a knitting sleeve and a tip positioning block 26 are mounted on a nozzle protruding cylinder 25 mounted on the nozzle upper and lower cylinders 24 so as to face the coaxial cable 10. .
[0007]
The nozzle up / down cylinder 24 is movable in the vertical direction as indicated by an arrow VIb in the figure, and in addition, the nozzle protruding cylinder 25 is movable in the axial direction of the coaxial cable 10 as indicated by the arrow VIc in the figure. Therefore, the vacuum nozzle 27 mounted on the nozzle protruding cylinder 25 can be brought into contact with the coaxial cable 10 as an object and sucked.
[0008]
FIG. 7 mainly shows various processing tools for the coaxial cable 10 mounted on the turntable 22, and each pair of knitting wire raising cylinders 28 and 28 arranged opposite to each other by 180 °, and the knitting wire peeling. A total of six cylinders including the return cylinders 29 and 29 and the endothelium cutting cylinders 30 and 30 are arranged radially so that the central angle is 60 °.
[0009]
The knitting wire raising cylinders 28, 28 temporarily remove the exposed root portions of the braided conductor 12 from the state of the coaxial cable 10 shown in FIG. 5 (1) by the knitting wire raising claws 28a, 28a provided at the ends of the cylinders. The braided conductor 12 is deformed by being clamped between the insulating inner skin 13 and the braided conductor 12.
[0010]
The braided stripping cylinders 29 and 29 are coaxially formed by stripping claws 29a and 29a provided on the tip of the cylinder, with the braided conductor 12 floating from the insulating endothelium 13 by the operation of the braid raising cylinders 28 and 28, respectively. The cable 10 is peeled back on the insulating sheath 11 on the opposite side to the terminal.
[0011]
Endothelial cutting cylinders 30 and 30 are respectively provided with an insulating insulating skin 13 of the coaxial cable 10 in which the braided conductor 12 is peeled off by the operation of the braided wire turning cylinders 29 and 29 at the tip of the cylinder. The central conductor 14 is left and removed by 30a and 30a.
[0012]
However, the turntable 22 is rotationally driven by the table rotating motor 31 as indicated by an arrow VII in the drawing, so that the desired cylinders 28, 28 to 30, 30 are on a plane perpendicular to the axis of the coaxial cable 10. The entire turntable 22 can be moved along the axial direction of the coaxial cable 10 as shown in FIG. 6, and the chucking operation of each cylinder is controlled by air pressure. The source.
[0013]
Next, actual processing of the coaxial cable 10 by the processing apparatus will be described.
First, in step 1 of FIG. 8 (1), the coaxial cable 10 in the state shown in FIG. 5 (1) is securely fixed at a predetermined position by the feeder clamp 21, and then the braid raising cylinder 28 of the turntable 22, The braided conductor 12 is deformed by temporarily clamping the exposed root portion of the braided conductor 12 by the braided nails 28a, 28a by 28, and is made to float from the insulating endothelium 13.
[0014]
This operation is repeated twice in the same manner while rotating the turntable 22 by the table rotation motor 31 and shifting the central angle by 60 ° as shown in the figure, and the braided conductor 12 is exposed by a total of three times of clamping. It is in a state of floating from the insulating endothelium 13 from the root portion to the entire periphery.
[0015]
Thereafter, in step 2 of FIG. 8 (2), the braided conductor 12, which is in a state of being floated all around from the insulating inner skin 13 of the coaxial cable 10, is used as a vacuum nozzle that also serves as a knitting sleeve. The tip of 27 is brought into contact and pressed to the direction of its root portion as shown by arrow VIIIb in the figure, whereby the braided conductor 12 is completely raised from the insulating endothelium 13.
[0016]
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 peeling cylinders 29, 29 of the turntable 22 are operated to show the peeling claws 29 a, 29 a. Each tip is brought into contact with each other as indicated by an arrow VIIIc.
[0017]
Semi-circular cutouts slightly larger than the diameter of the insulating endothelium 13 are formed at the tips of the peeled claws 29a and 29a, and these tips are brought into contact with each other as shown by an arrow VIIIc in the drawing. As a result, a round hole is formed in the braided conductor 12 that can be inserted through the insulating endothelium 13 but is raised all around it.
[0018]
Accordingly, when the single claw robot 23 is slid and moved in accordance with the axial position of the coaxial cable 10 as shown by the arrow VIIId in a state where the tips of the peeling claws 29a and 29a are kept in contact with each other, the state that has occurred The braided conductor 12 is peeled off from the exposed root portion to the insulating skin 11 side.
[0019]
Thereafter, in Step 4 of FIG. 8 (4), the endothelium cutting cylinders 30 and 30 are operated in place of the knitting wire peeling cylinders 29 and 29, and the coaxial cable 10 is peeled off as indicated by an arrow VIIIe in the drawing. The insulating endothelium 13 is cut by the endothelium cutting claws 30a, 30a at a position slightly closer to the end of the coaxial cable 10 than the base position of the braided conductor 12.
[0020]
At this time, both ends of the endothelium cutting claws 30a and 30a are formed with semicircular cutouts slightly larger than the diameter of the central conductor 14, and the insulating endothelium 13 is cut by contacting these tips. However, the central conductor 14 inserted through the central shaft portion is not cut.
[0021]
At this time, if the position where the coaxial cable 10 is in contact is sucked by the vacuum nozzle 27 at this time, the turntable 22 and the vacuum nozzle 27 are slid and moved as shown by an arrow VIIIf in FIG. The insulating endothelium 13 leaves the central conductor 14 and is separated from the coaxial cable 10 while being sucked by the vacuum nozzle 27. As a result, the end of the coaxial cable 10 is processed as shown in FIG. Complete.
[0022]
[Problems to be solved by the invention]
In the processing apparatus as described above, as shown in FIG. 7, three types of cylinders must be mounted on the turntable 22 in pairs, and the turntable 22 is rotationally driven. The configuration becomes very complicated, such as the need for the rotary motor 31 and the single-axis robot 23 for sliding movement.
[0023]
At the same time, when focusing on one type of cylinder, for example, the knitting cylinders 28, 28, a pair having a central angle of 180 ° has to be formed in relation to the other cylinders. In order to clamp the claws 28a, 28a over the entire circumference of the coaxial cable 10 as shown in (1), for example, the center angle is rotated three times in total while rotating the turntable 22 by 60 °. There is a problem that the clamping operation needs to be performed and the time required for the work becomes long.
[0024]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coaxial cable processing apparatus capable of simplifying the structure as much as possible and reducing the time required for processing. There is.
[0025]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a holding means for holding a coaxial cable having a predetermined length removed from the end of the insulating skin, and a braid of the coaxial cable held by the holding means that is exposed by removing the insulating skin. The conductor base portion is simultaneously sandwiched from three locations along a plane perpendicular to the axis of the coaxial cable, and rotated around the axis of the coaxial cable along the plane perpendicular to the axis of the coaxial cable. The base portion of the braided conductor is pushed in a total of six locations, and the braided conductor is in a state of floating from the insulating endothelium inside thereof, and the coaxial cable is centered along a plane perpendicular to the axis of the coaxial cable. Braided wire raising means arranged uniformly in the circumferential direction, and has an inner diameter slightly larger than the outer diameter of the insulating endothelium, and is abutted against the coaxial cable and floats from the inner insulating endothelium by the braided wire raising means State A first cylindrical member that is in a state where the braided conductor is pressed to its root portion and is raised, and the first cylindrical member is coaxially provided on the first cylindrical member and has an inner diameter that is outside of the insulating sheath of the coaxial cable. A second cylindrical member that is formed slightly larger than the diameter and that presses the braided conductor raised by the first cylindrical member at the tip surface and peels it back to the insulating skin side. And
[0026]
With such a configuration, it is only necessary to provide the above-described knitting means as processing tools arranged in the same circumference, and it is not necessary to adopt a structure for moving it along the axial direction of the coaxial cable. Therefore, the overall structure becomes extremely small and simple, and the number of components of the knitting line raising means itself can be increased. As a result, the time required for processing can be shortened.

In addition, the braid raising means rotates about the axis of the coaxial cable along a plane perpendicular to the axis of the coaxial cable, and sandwiches the root portion of the braided conductor in two times before and after the rotation. Features.
[0028]
In addition , the position of the knitting raising means can be controlled by a cylinder or the like in two alternatives before and after the rotation, and it is not necessary to carry out complicated rotation angle control, etc. Can contribute to downsizing.

DETAILED DESCRIPTION OF THE INVENTION
A coaxial cable processing apparatus 40 according to an embodiment of the present invention will be described below with reference to the drawings.
[0030]
In this case, the processing of the coaxial cable 10 is performed from the state shown in FIG. 5A to the step of peeling the braided conductor 12 (corresponding to step 3 in FIG. 8C), and the subsequent insulation. The illustration and description of the process of excising the endothelium 13 is omitted.
[0031]
1 to 3 show the external configuration, FIG. 1 is a plan view, FIG. 2 is a side view, and FIG. 3 is a sectional view mainly showing the configuration of a three-jaw chuck taken along the line II-II in FIG. It is.
[0032]
1 and 2, the coaxial cable 10 is detachably held on a feeder clamp 41 by the operation of a clamp cylinder 45, and a three-claw chuck 42 and a sleeve portion 44 are disposed corresponding to the terminal position where processing is performed. ing.
[0033]
The three-jaw chuck 42 has three knitting wire raising claws 43, 43, 43 as shown in FIG. 3 along a plane perpendicular to the axis of the coaxial cable 10 and a central angle of 120 ° about the coaxial cable 10. The base portion of the braided conductor 12 that is mounted in a radial manner so that the insulation sheath 11 of the coaxial cable 10 is removed and exposed is temporarily clamped by the braids 43, 43, 43. Thus, the braided conductor 12 is made to float from the insulating endothelium 13.
[0034]
The three-jaw chuck 42 is rotated by an angle of 60 ° on the plane perpendicular to the axis of the coaxial cable 10 by the chuck rotating cylinder 46, and the rotation position is in two stages by the operation of the chuck rotating cylinder 46. The selection is fixed to one of these.
[0035]
The sleeve portion 44 includes two sleeves, that is, a knitting wire raising sleeve 47 having an outer diameter substantially equal to that of the coaxial cable 10, and a knitting wire peeling sleeve having an inner diameter slightly larger than the outer diameter of the knitting wire raising sleeve 47. 48, the knitting wire raising sleeve 47 is driven by the knitting wire raising cylinder 49, and the knitting wire peeling sleeve 48 is driven by the knitting wire peeling cylinder 50 independently in the axial direction thereof. And abutted against the coaxial cable 10.
[0036]
A circular hole having an inner diameter slightly larger than the outer diameter of the insulating inner skin 13 of the coaxial cable 10 is further formed on the end face of the knitting wire raising sleeve 47 that is in contact with the coaxial cable 10.
[0037]
Reference numeral 51 denotes an emergency stop button, 52 denotes a clamp release button for releasing the holding of the coaxial cable 10 by the feeder clamp 41, and 53 denotes a machining start switch 53.
[0038]
Next, the actual processing of the coaxial cable 10 by the processing device 40 will be described.
First, in step 1 of FIG. 4 (1), the coaxial cable 10 shown in FIG. 5 (1) is securely fixed at a predetermined position by the feeder clamp 41 and then placed on the three-jaw chuck 42. The braided conductor 12 is deformed by temporarily clamping the exposed root portion of the braided conductor 12 with the three radially arranged braid raising claws 43, 43, 43, and is made to float from the insulating endothelium 13. .
[0039]
This operation is performed by temporarily clamping the braided conductor 12 with the braid raising claws 43, 43, 43 as indicated by arrows IVa, IVa, IVa at the normal position shown in FIG. After the three-jaw chuck 42 is rotated by 60 °, the braided conductor 12 is temporarily clamped by the braid raising claws 43, 43, 43 again as shown in FIG. 4 (1) -b. . As a result of the two clamping operations, the exposed root portion of the braided conductor 12 is temporarily pushed at convenient 60 ° intervals around the entire circumference, and the braided conductor 12 is completely removed from the exposed root portion. It is in a state of floating from the insulating endothelium 13 over the periphery.
[0040]
Thereafter, in step 2 of FIG. 4 (2), the braided conductor 12, which is in a state of being floated from the insulating inner skin 13 of the coaxial cable 10, is brought into contact with the tip of the sleeve 47. As shown by an arrow IVb in the figure, the braided conductor 12 is completely raised from the insulating inner skin 13 by being pressed to a position where the insulating outer skin 11 is located.
[0041]
At this time, since the circular hole having an inner diameter slightly larger than the outer diameter of the insulating endothelium 13 is formed at the tip of the knitting wire raising sleeve 47 as described above, the insulating endothelium 13 is inserted into the circular hole and knitted. The braided conductor 12 is pressed by the ring-shaped front end surface of the line raising sleeve 47 so as to be completely raised.
[0042]
Next, in step 3 of FIG. 4 (3), the knitting wire stripping sleeve 48 provided coaxially with the knitting wire raising sleeve 47 is operated by the knitting wire stripping cylinder 50 as shown in FIG.
[0043]
In this case, as described above, the inner diameter of the braided stripping sleeve 48 is larger than the outer diameter of the braided raising sleeve 47 and the thickness of the braided conductor 12 is taken into account. It is set slightly larger than the diameter.
[0044]
Therefore, when passing through the insulating endothelium 13 where the tip of the braided line peeling sleeve 48 is raised, it is peeled back on the insulating skin 11 in the left direction in the figure.
[0045]
After the stripping of the braided conductor 12 is completed in this way, the process proceeds to step 4 in FIG. 4 (4), and the braided stripping cylinder 50 and the braiding raising cylinder 49 are operated so as to gently move as shown by an arrow IVd in the drawing. Then, the knitting wire stripping sleeve 48 and the knitting wire raising sleeve 47 are separated from the coaxial cable 10, and the processing step for the coaxial cable 10 is completed.
[0046]
When the coaxial cable processing apparatus 40 is configured as described above and the coaxial cable 10 is processed, a turn on which 3 to 6 processing tools of the conventional coaxial cable processing apparatus 20 shown in FIG. Compared with the table 22, only the braid raising nail 43 used for raising the braided conductor 12 may be mounted on the three nail chuck 42, so that the three nail chuck 42 itself is sufficiently small. It can be.
[0047]
Moreover, the number of braid raising claws 43 to be placed is, for example, three, and the braided conductor 12 is raised by changing the rotation angle of the three claws chuck 42 and clamping twice in total.
[0048]
Therefore, in the conventional coaxial cable processing apparatus 20, the braided conductor 12 is raised by a total of three times of clamping by the braid raising cylinder 28 in which two braid raising claws 28a are formed. This process can reduce the time by about 33%.
[0049]
In addition, in the coaxial cable processing apparatus 20, in order to adjust the rotational position of the turntable 22 on which a total of 3 to 6 processing tools are mounted, the position is controlled by driving the table rotation motor 31. However, in the coaxial cable processing apparatus 40 according to the present invention, it is only necessary to switch the position of the three-jaw chuck 42 to any one of the two stages. There is no need to perform control.
[0050]
Further, as means for peeling off the braided conductor 12, the braided wire turning cylinder 29 formed with the turning claws 29a as in the coaxial cable processing apparatus 20 is not slid by the single axis robot 23, but the braided wire of the sleeve portion 44 is used. Since the stripping sleeve 48 is squeezed by the operation of the braided stripping cylinder 50, a large and expensive configuration such as the single-axis robot 23 can be eliminated, which can contribute to downsizing and cost reduction of the apparatus.
[0051]
In addition, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
[0052]
Further, the above embodiments include inventions at various stages, and various inventions can be extracted by appropriately combining a plurality of disclosed constituent elements. For example, even if some constituent elements are deleted from all the constituent elements shown in the embodiment, at least one of the problems described in the column of the problem to be solved by the invention can be solved, and described in the column of the effect of the invention. In a case where at least one of the obtained effects can be obtained, a configuration in which this configuration requirement is deleted can be extracted as an invention.
[0053]
【The invention's effect】
According to the first aspect of the present invention, it is only necessary to provide the knitting wire raising means as the processing tool arranged on the same circumference, and it does not adopt a structure for moving it along the axial direction of the coaxial cable. Therefore, the overall structure becomes extremely small and simple, and the number of components of the knitting line raising means itself can be increased, and as a result, the time required for processing can be shortened.
[0054]
According to the second aspect of the invention, in addition to the effect of the first aspect of the invention, the position of the knitting line raising means can be controlled by one of two choices before and after the rotation by a cylinder or the like. Therefore, it is not necessary to perform a rotation angle control or the like, so that the structure can be further simplified and the entire apparatus can be reduced in size.
