Patent ID: 8563840

Claim:
An apparatus for making a carbon nanotube composite wire structure, the apparatus comprising a wrapping unit; a supply unit configured to feed a linear structure to the wrapping unit; and a collecting unit configured to pull the linear structure and collect the carbon nanotube composite wire structure formed on the wrapping unit, wherein the wrapping unit comprising: a hollow rotating shaft defining an axis, wherein the supply unit is adapted to feed the linear structure through the hollow rotating shaft; a growing substrate with a carbon nanotube array; a face plate mounted on the hollow rotating shaft, wherein a shape of the face plate is a frustum pyramid, the frustum pyramid includes a plurality of side surfaces configured to load the carbon nanotube array growing on the growing substrate, the carbon nanotube array being used to form a carbon nanotube structure; and a drive mechanism configured to drive the hollow rotating shaft rotating around the axis, and wind the carbon nanotube structure around the linear structure to form the carbon nanotube composite wire structure.
