Background The existing wind power blade balancing schemes are two, namely (1) balancing according to the mass and the mass moment of the blade, and (2) balancing according to the maximum mass moment of the blade. The balancing is performed according to the mass and the mass moment of the blade, namely, the balancing is performed according to the fact that the mutual difference of the mass and the mass moment in the wind power blade sleeve does not exceed the standard regulated by the industry. Therefore, when the blades are weighted, the same set of three blades must wait for all production and weighing to finish before being weighted uniformly, and the weighting method has the following limitations: The first finished blade needs to occupy stations for a long time to wait for the subsequent blades, at least two stations are wasted, as the quantity of wind power blades is increased, space resources of a factory building are tense, the space rotation rate of the blades waiting for counterweight can be reduced, in addition, before three blades are balanced and complete, the counterweight can be carried out after the first finished blade needs to wait for the completion of the second two blades, and the counterweight scheme of the complete blade needs to be determined after the completion of weighing of the third blade, so that the delivery time of the blades is prolonged. The balancing according to the maximum mass moment has the defect that the dosage of the balancing material is excessive, the blades are inevitably deviated within an acceptable range in actual production, individual differences of the blades in a weighing stage are increased after tolerance accumulation of each procedure, more balancing material is needed to be added for balancing the mass moment by taking the blade with the maximum mass moment as a reference, waste of the balancing material is caused, and the improvement of the balancing efficiency is not facilitated.
