[0034] The working principle of a semi-automatic winding machine for winding large-sized nanocrystalline magnetic rings provided by the utility model is as follows: before work, the staff first adjusts the size of the nanocrystalline magnetic ring 13 to be wound, and the staff first starts the motor 2 121 by adjusting the control switch group 2. The operation of the motor 2 121 drives the screw rod 122 to rotate, and the rotation of the screw rod 122 drives the fixed frame 124 to move up and down under the limiting effect of the avoidance groove 123.

At the same time, the left and right sides of the nanocrystalline magnetic ring 13 are contacted and locked by the limit plate 87, so The nanocrystalline magnetic ring 13 rotates between the rollers 10, thereby realizing the rotation of the rotating frame 11 and driving the winding drum 7 to make a circular motion with the center of the rotating frame 11. At the same time, since one end of the filter coil of the winding drum 7 is fixed on the nanocrystalline magnetic ring 13, the winding drum 7 rotates itself, and the filter coil is wound on the part of the nanocrystalline magnetic ring 13 corresponding to the upper and lower positions of the rotating frame 11. At the same time, the nanocrystalline magnetic ring 13 rotates to align the unwound position with the rotating frame 11 up and down, thereby the nanocrystalline magnetic ring 13 can be semi-automatically wound, saving manpower of the staff and improving work efficiency. After the winding is completed, the filter coil is cut off, an upward thrust is applied to the limit plate 87, the lock is released, and then the nanocrystalline magnetic ring 13 is taken out.
