The highly automated winding process improves production efficiency. At the same time, the automatic cutting device ensures the accuracy of the length of high-strength cables for new energy vehicles, reduces material waste, and enhances operational safety. The design flexibility of the system also ensures the ability to quickly adapt to high-strength cables for new energy vehicles of different specifications.

[0051] Embodiment 3: Combining with Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 In addition to the contents of the above embodiments, the fixing module includes a clamping unit for adapting and clamping the high-strength cable for new energy vehicles and an angle adjustment unit for driving the clamping unit to rotate relative to the drum.

[0052] The clamping unit includes a tubular structure pipe fixed to the outer wall of the drum, a plurality of airbag balls sequentially arranged around the inner wall of the pipe, an inner channel arranged in the pipe wall of the pipe, a plurality of through holes respectively arranged on the inner wall of the pipe and respectively connected with each inner channel, a plurality of micro air pumps fixed to the inner wall of the drum, an air guide tube partially placed in the inner channel and one end of which passes through the through hole to be connected with the airbag ball and the other end of which passes through the pipe and the drum in sequence to be connected with the micro air pump, and a micro pressure sensor respectively laid on each airbag ball for monitoring the contact pressure between the airbag ball and the high-strength cable for new energy vehicles.

[0056] The micro pressure sensor monitors the contact pressure between the airbag ball and the high-strength cable for new energy vehicles in real time. When the pressure monitored by the micro pressure sensor is too large or too small, the system will automatically adjust the output of the micro air pump to ensure that the airbag ball provides appropriate clamping force, which will not damage the high-strength cable for new energy vehicles, and can also prevent the high-strength cable for new energy vehicles from sliding or dislocating during the winding process, thereby achieving adaptive clamping of high-strength cables for new energy vehicles with different diameters.

It not only realizes the adaptability and flexibility of high-strength cables for new energy vehicles with different diameters, but also ensures the uniform distribution and stability of high-strength cables for new energy vehicles during the winding process. Through the cooperation of micro pressure sensors and automatic regulating air pumps, the system can accurately control the clamping force, avoid damage to high-strength cables for new energy vehicles and improve production quality.
