Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a conductive wire used in J-Robots 1 to 1, etc., and a method for manufacturing the same.

In recent years! 1! J5 to I to Robo 1 to live 77? There are some remarkable things, but especially that Itfi! The movements of robots are intense, and the number of repetitions of movements is high.
The conductive wire connected to M+ is subject to many harsh conditions and generally has a short lifespan.

The object of the present invention is to provide a conductive wire having extremely high elasticity and flexibility to withstand severe motion and momentum, and a method for manufacturing the same.

Next, the structure of the conductive wire of the present invention will be explained based on the drawings.

The wire 1 of the present invention consists of a highly elastic core material 11 and a strand 12 spirally wound around the core material 11 (t1).

<A> Core material The core material 11 is a fiber such as stretchable spandex, stretchable synthetic rubber, or stretchable natural rubber.

And its cross-sectional shape is a circle.

Curon wire The cable wire 12 is a conductive wire material such as copper.

The cross-sectional shape is not particularly limited, and may be any shape such as a circle, ellipse, square, or rectangle, but in this embodiment, it is assumed to be rectangular.

(c) Conductive wire The conductive wire 1 is made by winding a cable wire 12 around a core material 11 in a spiral shape with close intervals. (Fig. 1.2) Next, the manufacturing method of the conductive wire 1 will be explained.
-f Manufacturing equipment will be explained 4.

Gui> Cable line drum The cable line drum 2 is a hollow cylinder for winding the cable line around its outer periphery, and has annular flanges 21.2 at both ends.
2 will be established.

A kite 23 is attached to one flange 21 through which the wire 12 passes.

A gear 24 is attached to the lower part of the flange 22 of one tube, and power is applied to rotate the movable key A725 and Iei1 together, and the peg 2 in the -;

The direction of rotation is the direction in which the cable wire 12 is unraveled when the wire drum 2 around which the wire 12 is wound rotates.

Also, the rotational speed must always be higher than a certain level, but the degree and reason for this will be discussed later. .

Feeding device Sandwiching the wire drum 2, feeding devices 3.4 are placed on both sides of the drum 2.
Established.

The feeding device 3.4 has the same structure as J3, and consists of two rolls that rotate in left and right opposite directions on axis 1 in V rows.

The feeding device rotates the core material 11 or the conductive wire in a fixed direction by sandwiching the conductive wire 1 wound with I-MI, 4A11, or strands 12 between two rolls, and rotating each roll at the same speed in opposite directions. send to

The two feeding devices 3.4 are of the same construction and have the same rotational direction iJ, but their rotational speeds are different.

In other words, in the direction of movement of the core material, the feeding device 3, which is located at the front of the tram 2 for strands, moves faster than the feeding device 4, which is located behind the drum 2. Keep the material under tension at all times d5<.

(Figure 3) Next, the manufacturing method will be explained.

<A> The core material 11 passes through the hollow part of the cable drum 2 and is fed in a fixed direction by two feeding devices that sandwich the strand drum 2 between them.

Since the feed device 3 on the downstream side rotates faster than the feed device 4 on the upstream side, the core material 11 is always under tension.

The reason for applying tension to the core material is that the core material 11 is made of elastic rubber, etc.
,, although it is not possible to accurately wind I in a spiral shape4
The strands 12, which protrude from the cable drum 2 rotating at high speed, pass through a guide 23 and move in a fixed direction.
It wraps around Δ11 in a spiral.

The following describes how high the rotational speed of the cable drum should be at this time and the reason for this. Core material 1
1 is made of a stretchable material, so when the rotational speed of the system wire drum is slow, the core material is pulled toward the guide side by the cable wire passing through the guide.

In such a state, it is not possible to wind the cable wire accurately around the core Io.

Therefore, by rotating the strand drum 2 faster, for example, the moving speed of the guide from point A to point B is increased, and the core material is stretched to one side to provide a distance of 4r. (Fig. 4) In other words, the rotational speed of the wire drum 2 is set to a speed that does not allow time for the core material to elongate in one direction.

In the manner described above, a conductive wire is manufactured by feeding the core material in a fixed direction while winding the wire around the core material.

<C> About the rotation of the strands According to the above winding method, the strands 12 only revolve around the core material 11 and do not rotate, so the strands 12 with a rectangular cross section
However, it can be wrapped tightly around the core material 11. (Fig. 2) Therefore, the wire drum 2 is rotated at extremely high speed.

Even if the strands 12 are twisted almost completely, the core material 1
It can be wrapped around the outer circumference of 1.

<2> Other embodiments One or more conductive wires of the present invention are bundled in the required number,
The surface of the bundle is further coated with an elastic material such as rubber or urethane.

It is also conceivable that this cable could be used as a large-capacity Kuku electric wire, which has a thick core and flexibility, and at the same time prevents the conductive wire from being cut by the outer horns.

Since the conductive wire of the present invention is as explained above, the following effects can be expected.

B) Since the strands are spirally wound around a stretchable core material, the completed conductive wire will have stretchability and flexibility even if the strands themselves are not stretchable.

<Opening> The core material inside the spirally wound 1C wire serves as a support member for the coil, and at the same time serves as a material to prevent deformation of the cable wire due to external shocks, etc.

It has elasticity, flexibility, and is resistant to external impacts, making it suitable for parts that move vigorously and repeat many times, such as robot arms.
