The invention discloses a
helical fiber grating manufacturing device and a manufacturing method thereof and relates to
helical fiber gratings. The device comprises a
direct current motor, a storage
pipe, a
metal rod, a heater, a temperature controller, a micro-channel, a power supply, a conductive base, a translation stage controller and an X-Y-axis precision translation stage. The manufacturing method comprises the following steps: adding electrostatic
spinning raw materials into the storage
pipe, regulating the temperature controller to heat so as to remove the
moisture in the
raw material, and regulating the temperature to the
melting point of the raw materials; inserting the
metal rod into a melt
polymer, extending out of a
discharge hole below the micro-channel, and regulating the rotating speed of the
direct current motor until the needle tip is coated by the melt
polymer, so that the molten liquid stably flows out; switching on the power switch, regulating the
voltage of the conductive base to a preset negative pressure, starting the electrostatic
spinning process, collecting electrospun fibers on the conductive base, reducing the temperature for curing in the
deposition process, and forming a
helical structure; enabling the X-Y-axis precision translation stage to drive the conductive base to move by virtue of the translation stage controller, thereby obtaining the helical
fiber grating with the controllable
diameter and screw
pitch.
