The winding head, the upper guide rod, and the lower guide rod are arranged in sequence from top to bottom, and the winding head, the upper guide rod, and the lower guide rod move synchronously in the vertical direction and rotate along the common axis of the upper guide rod and the lower guide rod in the horizontal direction. The first pulley is coaxially fixedly connected with an eccentric crank, and the first pulley is connected with the eccentric crank, a connecting rod, and a sliding block in sequence. The eccentric crank drives the rotation of the first pulley, and the eccentric crank and the connecting rod form an eccentric crank sliding block mechanism. The sliding block is hingedly connected with the connecting rod and moves reciprocatingly in the vertical direction. The second driving pulley is connected with a sectorizer. The sectorizer outputs a reciprocating swing action within a certain angle range. The winding head and the upper guide rod are driven to rotate by the second motor and the sectorizer. The sectorizer drives the upper guide rod to reciprocate through a sector gear, thereby realizing the reciprocating swing of the winding nozzle on the winding head. The second motor also drives the upper guide rod to reciprocate vertically. The above-mentioned winding mechanism has the following disadvantages:

[0003] Because the number of winding slots and the angle of the winding slots of different specifications of stators are inconsistent, the angle of the swing of the winding nozzle of the winding mechanism is inconsistent. Therefore, when winding different specifications of stators, the above-mentioned winding mechanism needs to replace sector gears of different sizes to adjust the swing angle of the winding nozzle. The replacement operation of the sector gears is troublesome, and the gears are replaced frequently, which results in poor meshing and unstable operation of the winding mechanism.
