[0002] Carbon nanotubes are one-dimensional nanomaterials that can be simply viewed as seamless, hollow nanotubes formed by curling graphene sheets. Their main performance advantages are: high strength, high electron mobility, excellent wave-absorbing electromagnetic shielding effect, extremely high electric-to-heat conversion rate of up to 99.8%, and infrared conversion efficiency of up to 83%.

The optional model of the tension sensor 41 is the WFTG-3-100N-50200-CXH sensor. The model of the substrate unwinding roll device 43 can be QZZ-FLW28-JD, and the substrate roll collected by the substrate collecting roll device 32 can be installed in the substrate unwinding roll device 43 for unwinding.

[0039] Furthermore, the drying module 5 includes: a metal coating box 51, a hot air dryer 52, a second automatic deflection correcting machine 53, a third automatic deflection correcting machine 54, and a drying module bracket 55.

The motor driving the carbon film material roll device 61 after stretching is connected to the signal of the tension sensor 41. The speed of the motor driving the carbon film material roll device 61 after stretching is controlled by the tension sensed by the tension sensor 41, thereby realizing the tension control of the carbon nanotube film during the stretching process. In addition, the carbon nanotube film will be immersed in alcohol before stretching, and the film will shrink and densify during the volatilization of the alcohol, thereby realizing the stretching and densification of the carbon nanotube film.

[0042] The above-mentioned first automatic deflection correcting machine 23, the second automatic deflection correcting machine 53, and the third automatic deflection correcting machine 54 can all be selected as PG200D50W230AL deflection correcting machine.

After unwinding, the laser cutting module 2 divides the carbon-carbon film material belt into a substrate 14 and a carbon film 15, wherein the carbon film 15 needs to be cut into a fixed width using a laser cutter 22. After the cutting is completed, the carbon film 15 is soaked in alcohol in the cleaning module 4. In the cleaning module 4, the tension sensor 41 is used to measure and feedback the size of the drawing force applied on the carbon film 15, and at the same time, the unwinding function of the final collected substrate 14 is provided. In the drying module 5, the carbon film 15 is dried before collection to ensure that the carbon film 15 is collected in a dry state, and the substrate 14 and the carbon film 15 are corrected before collection. The metal coating box 51 is used to complete the metal deposition on the surface of the carbon film 15. In the winding module 6, the carbon film 15 and the substrate 14 are combined and collected after drawing, and the carbon film material roll device 61 after drawing provides the drawing force for the carbon film 15 during the whole drawing process. Through this design, a longer high-performance carbon nanotube film product can be achieved, and the preparation efficiency and automation of the carbon nanotube film product can be improved.
