低下し、コイルボビンの生産性を損なうことになる。[Problems to be Solved] When the coil bobbin is not symmetrical with respect to the insertion hole,
When the winding shaft is rotated, eccentricity occurs, the rotating shaft moves, and the wire is not wound evenly. Further, in the case of a thin wire having a wire diameter of about 0.08 mm used for a small coil, the coil bobbin may be broken even by a slight deformation.
Further, an asymmetric force due to the centrifugal force acts to cause resonance, and the coil bobbin may escape from the winding shaft or may deform the winding shaft, causing damage to the winding machine.
If the winding speed is slowed down to prevent this, the winding efficiency is lowered, and the productivity of the coil bobbin is impaired.
