Description

Technical Field

[0001] The utility model relates to the technical field of circuit breaker coils, in particular to a six-head coil winding device. Background Art

[0002] Six-head coils are widely used in circuit breakers. The existing six-head coils are automatically wound by a winding device. In order to fix the six-head coils, the traditional winding rotation device often uses a coil fixing head that can fit tightly with the six-head coil to position it. However, there will be errors in the dimensions of the six-head coils during mass production. In addition, the fastening force of the coil fixing head will decrease due to frequent plugging and unplugging, resulting in uneven winding, large swing amplitude, and reduced winding accuracy during the winding process of the six-head coil, which greatly delays production and has low production efficiency. The existing coil fixing head is not convenient to use. Therefore, it is necessary to develop a six-head coil winding device that can be flexibly adjusted and fixed according to the six-head coil.
