Description

Automatic strip device for stripping cable

The present invention relates to an automatic cable end strip device.

The rapid development of telecommunication technology has led to the development of various cables that are optimally designed for the individual needs of each sector. For example, a shielding layer is provided inside the high voltage transmission cable applied to an ultra high voltage power transmission cable or an electric vehicle to shield the electromagnetic force so that the electromagnetic force generated from the inner core of the cable does not affect the outside of the cable. In the case of communication cables, a shielding layer is built-in so that external electromagnetic forces do not affect the core and cause errors in transmission data.

1 is a perspective view showing a cable end structure of a type in which the shielding layer is incorporated.

The cable 11 shown in FIG. 1 includes a core wire 13 made of a conductor and extending in the longitudinal direction, an insulating layer 15 surrounding the core wire 13 and insulating the core wire to the outside, and the insulating layer A shielding layer 17 surrounding the shielding layer 17 and shielding the electromagnetic wave generated from the core 13 from leaking to the outside or preventing external electromagnetic waves from affecting the core 13, and surrounding the shielding layer 17. Insulation coating 19 is included.

The said shielding layer 17 is cut | disconnected for some time in order to connect to the connection object external to the core wire 13. That is, when the insulating layer 15 is peeled by the required length to expose the core wire 13, at least the length of the insulating layer 15 is peeled off. This is to prevent the shielding layer 17 from electrically contacting the core 13 as well as the connection object.

Furthermore, the shielding layer 17 whose end is cut to some extent may be removed as much as possible from the exposed part of the insulating coating 19 so as not to interfere with the supply of power or the transmission and reception of data or to be awkward in view of the cable construction work. Tightened in a folded state.

In any case, in order to connect the cable 11 to an external connection object, the end portion of the cable 11 must be peeled in any shape. By the way, the conventional working method of peeling the end part of the cable 11 has been performed by a worker by hand tools, such as a knife or industrial scissors, without any dedicated tool or mechanism. This method includes a process of cutting off and peeling off the insulating layer 15, the shielding layer 17 and the insulating coating 19 using a knife or scissors, and is very inconvenient and time-consuming. Not only can the hand be injured, but also has the disadvantage that the shape after cutting is not neat.

FIG. 12 is a view illustrating a cable transfer unit in an automatic cable end strip device according to an embodiment of the present invention, and FIG. 13 is a view for explaining the operation principle of the cable transfer unit shown in FIG. 12.

Basically, the cable conveying part 41 in the shielding layer finishing apparatus according to the present embodiment is located opposite to the front of the processing part and reciprocates in the direction orthogonal to the processing direction and the direction perpendicular to the processing part, and the strip The cable is to be transported to the cut portion, the cut portion to the first thin skin, and the first thin skin to the second thin skin.

As shown in the drawing, the cable transfer part 41 is mounted on the upper surface of the base plate 41a fixed to the upper part of the table 23 and the base plate 41a, and guides the first actuator 41c. A sliding plate 41b reciprocating in the direction of arrow X, a plurality of fixing blocks 41f fixed to both ends of an upper surface of the sliding plate 41b, and a guide rod horizontally supported by the fixing block 41f. (41g).

In addition, the upper portion of the sliding plate (41b) is provided with a second actuator (41h) for reciprocating the cable support plate (41d) and the cable support plate (41d) in the direction of the arrow Y. The cable support plate 41d is a plate member having a predetermined thickness and width, and both ends thereof are supported by the guide rod 41g in a state where the width direction thereof is erected in the vertical direction. Since the cable support plate 41d moves in the direction of arrow Y on the sliding plate 41b, the cable support plate 41d is free in the X-Y direction motion, that is, two-dimensional motion, in the upper part of the cable 23.

Reference numeral 41e denotes a cable groove. The cable groove 41e is a groove for supporting the cable 11 and accommodates the cable when the cable 11 passes through the cable support plate 41d during transportation. In particular, the spacing between the cable grooves 41e is equal to the spacing between the cable holders in the cut portion 25, the first thin skin 27, and the second thin skin 29.

In addition, the upper actuator (41m) is provided in the vertical upper portion of the cable groove (41e). The upper actuator 41m is vertically fixed to the upper frame 41k disposed above the table 23, and has a push rod 41n on the operation rod. The push bar 41n is an annular member, and when the cable 11 spans the cable groove 41e, it is lowered by the operation of the upper actuator 41m to bring the cable 11 to the cable groove 41e side. Press to support it.

On the other hand, two holder portions are installed in the cable support plate 41d. The holder part holds the cable to be transported, reciprocates by the X-Y direction movement of the cable support plate 41d and serves to move the cable to the next process.

Of the two holder parts, the holder part on the left side of the drawing reciprocates between the cut part 25 and the first thin skin part 27, and cuts the cable processed by the cutting line 11a by the cut part 25. Transfer to one thin skin (27). In addition, the first holder portion, the new cable provided from the outside by the operator to move to the cut portion 25 also serves to take over the cable holder 25n of the cut portion 25.

In addition, the holder part on the right side of the drawing transfers the cable peeled by the first thin skin to the second thin skin while reciprocating between the first thin skin 27 and the second thin skin 29.

As shown in Figs. 13A and 13B, the holder part is fixed to the cable support plate 41d, but is operated by the operation of the finger drive actuator 41q and the finger drive actuator 41q, which are fixed to raise and lower the operation rod. A horizontal lifting block 41r for elevating and a pair of vertical rods 41s fixed to both ends of the elevating block 41r and extending vertically.

In addition, a rotation rod 41t is linked to the upper end of each of the vertical rods 41s by a connecting pin 41v. The rotating rod 41t is rotatably connected to the cable support plate 41d via the rotating shaft 41u, and the lifting block 41r is raised in the arrow g direction to move the arrow h direction about the rotating shaft 41u. Rotate into

In addition, the finger 41p is fixed to the inner side of the upper end of the pivot rod 41t. The fingers 41p are close to each other and meet each other when the lifting rod 41t rotates in the direction of the arrow n by the lifting block 41r descending. The groove 41w is formed in the opposing surface of the finger 41p. The groove 41w is a groove that receives and clamps the cable 11.

Eventually, as the finger drive actuator 41q is operated, the finger 41p is raised to grab the cable 11 to transfer the cable to the next process, or to descend to let the cable holder of the processing unit take the cable. The operation can be repeated.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
