Abstract

A fiber winding device includes a spool assembly having a plurality of bobbins provided around a spiral wire in a circumferential direction to form a spool surface, a guide ring provided at a front part of the center of the spool assembly in a direction oblique to the spool surface, and a wire transfer unit for transferring the spiral wire to pass through the guide ring. The spiral wire is disposed to perpendicularly pass through the center of the guide ring. The spool assembly is disposed in a direction oblique to the wire, and fibers from the plurality of bobbins are wound on the spiral wire along the guide ring. In addition, by sequentially arranging a plurality of fiber winding devices along the spiral wire, fibers in multiple layers can be wound on one spiral wire sequentially and continuously.

First claim

1 . A fiber winding device comprising:
a spool assembly comprising a plurality of bobbins provided around a spiral wire in a circumferential direction, the spool assembly being configured to form a spool surface; a guide ring provided at a center of the spool assembly in a direction oblique to the spool surface; and a wire transfer unit configured to transfer the spiral wire to pass through the guide ring, wherein the spiral wire is disposed to perpendicularly pass through a center of the guide ring, the spool surface of the spool assembly is disposed in a direction oblique to the spiral wire, and fibers from the plurality of bobbins are wound on the spiral wire along the guide ring.

2 . The fiber winding device of claim 1 , wherein
all of the plurality of bobbins are configured to move in one direction to wind fibers in one direction, or some bobbins are configured to move in directions opposite to each other to wind fibers in a woven form.

3 . The fiber winding device of claim 1 , further comprising a bobbin carrier to which a tension control unit configured to control tension of fibers is attached.

4 . The fiber winding device of claim 1 , wherein
the wire transfer unit is installed in plurality along the spiral wire.

5 . The fiber winding device of claim 1 , wherein
the wire transfer unit comprises a first roller configured to provide a transferring force to the spiral wire and a second roller configured to prevent the spiral wire from leaving, the first roller is disposed on both sides of the spiral wire, and the second roller is disposed on at least one of the inside or outside of the spiral wire.

6 . The fiber winding device of claim 5 , wherein
the first roller has a tapered shape, and a taper portion having a wide diameter of the first roller is disposed toward the outside of the spiral wire.

7 . The fiber winding device of claim 1 , further comprising:
a wire transfer speed measurement unit; and a roller motor rotation speed control unit configured to control a rotation speed of a motor driving rollers of the wire transfer unit.

8 . The fiber winding device of claim 1 , further comprising:
a wire transfer speed measurement unit; and a bobbin rotation speed control unit configured to control rotation speeds of the bobbins.

9 . A fiber winding system comprising
the fiber winding device of claim 1 , wherein the fiber winding device is provided in plurality and arranged in sequence along the spiral wire.

10 . A composite structure manufactured using the fiber winding device of claim 1 .

11 . A composite structure manufactured using the fiber winding system of claim 9 .
