Abstract

This invention relates to the field of dispensing system equipment technology, specifically to a servo parameter adjustment method, system, equipment, and medium for a five-axis dispensing system. It establishes a dual-channel communication architecture, separating motion control and parameter adjustment paths. By defining thresholds, deltaCorner, and overshoot values ​​to quantify accuracy indicators, and through initialization, inertia ratio acquisition, servo rigidity estimation, and single-axis coarse and fine-tuning of the X / Y axes, the servo parameters are automatically adjusted. The PC software collects encoder data in real time, calculates the indicator parameters, and dynamically optimizes the speed feedforward and torque feedforward gains based on accuracy requirements until the target is met. This invention solves the problems of traditional manual parameter adjustment, which relies on experience, is inefficient, and has subjective accuracy, improving debugging efficiency and dispensing accuracy. It is applicable to five-axis dispensing equipment in the fields of electronics manufacturing and medical device manufacturing.
