[0044] S4. Start the main motor and the vortex fan connected to the thread suction tube, implement the coordinated actions of bobbin thread release, active roller and driven roller thread drawing, and thread suction tube thread suction, until the sensor in the thread suction tube no longer detects that there is excess thread entering the thread suction tube;

[0045] S5. The robot grabs the new thread until it reaches the bobbin. At this time, the lateral positioning arm starts to drive the pressure column to fit the side wall of the bobbin to achieve the circumferential fixation of the thread end of the new thread and the bobbin; then the main motor is started to drive the bobbin to rotate and wind the new thread onto the bobbin;

[0046] S6.
