Technical Field

The invention relates to the technical field of light coil manufacturing, in particular to a coil winding device and a winding method.

Background

The moment coil is used for providing exciting current and is sensitive to external acceleration together with other components, the evaluation on the winding quality of the coil comprises the appearance quality, the number of layers, the weight, the resistance value and the like of the winding, and the consistency of the winding parameters of the moment coil has important influence on the performance index of a superior component.

The coil is formed on coil skeleton by the coiling of copper core enameled wire, first circle enameled wire definition is the lead-out wire, because the coiling machine that uses does not have the tailstock, can't be through the enameled wire of butt structure coiling system coil skeleton, original coiling frock is the bar copper, adopt and twist screw form installation coil skeleton, the enameled wire lead-out wire passes through behind the coil skeleton breach position, bond on the coil skeleton outer wall with the adhesive tape, because the coil skeleton breach is sharp, the lead-out wire has the coating to drop or the fish tail risk, coil skeleton relies on the inner chamber location alone, it is different to place different coil skeleton positions, different coil home position discrepancy can be greater than 0.5 circle, the state that leads to the coil coiling is inconsistent, the later stage parameter matches the difficulty.
