Initial error parameter correction method and equipment of automatic arch wire bending device, medium and product

Abstract

The invention provides an initial error parameter correction method for an automatic arch wire bending device, and the method comprises the steps: obtaining initial data, and obtaining a plurality of groups of initial motor rotation angle data; measuring the actual angle, and measuring the actual bending angle of the arch wire after the automatic arch wire bending device bends the arch wire according to the initial motor rotation angle data; conducting data fitting, specifically fitting different types of equations by using the actual bending angle of the arch wire and the corresponding initial motor rotation angle data, evaluating the fitting degree of each equation, and finding out the most relevant fitting curve equation as a final fitting function according to the fitting degree evaluation result; and conducting parameter correction, specifically correcting the initial motor rotation angle data through the final fitting function. The fitting function is obtained by inputting a plurality of groups of initial data and carrying out actual testing. During subsequent formal use, a data value is input, and a final value is obtained through the fitting function, so that springback and various errors existing in the device are eliminated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method, equipment, medium and product for correcting initial error parameters of an automatic archwire bending device. Background technique [0002] Malocclusion is a common oral disease, the main manifestations of which are irregular arrangement of teeth, abnormal tooth-jaw relationship between the upper and lower dental arches, and abnormal size, shape and position of the jaw. Fixed orthodontic technology is a common and effective orthodontic treatment method at present. The fixed orthodontic technology is mainly realized by brackets and orthodontic archwires. Force, moving teeth tends to level off, restore normal bite. In the process of orthodontic treatment, especially the fixed correction of the lingual side, it is often necessary to bend arch wires with different angles and put them into the lingual inclined groove bracket for use. At present, personalized lingu...
