Transformer coil winding apparatus for winding wire on coil bobbin with correctly counting winding number and enabling high speed winding operation

摘要

A transformer coil winding apparatus for winding a winding wire (6) on a coil bobbin (1) comprises a rotating drive mechanism (2a to 2d, 2'a to 2'd, 3) for rotatably driving the coil bobbin (1) by a friction force between the coil bobbin (1) and the rotating drive mechanism (2c, 2'c; 2d, 2'd). Further, the transformer coil winding apparatus comprises a detection unit (7) provided on said coil bobbin (1), a rotation number counting unit (109) for counting number of rotations (C1) of the coil bobbin (1) on the basis of the output of the detection unit (7), and a drive unit (5) for rotatably driving the rotating drive mechanism (2a to 2d, 2'a to 2'd) in response to the number of rotations (C1) on the rotation number counting unit (109). Therefore, the production cost for the transformer can be lowered.
