AI Technical Summary

Technical Problem

Existing motor coil pressing control methods are unable to simultaneously meet the preset target pressing force and target termination position when faced with dynamic disturbances such as material batch differences, ambient temperature changes, and equipment state drift, resulting in insufficient process stability and consistency.

Method used

By constructing a process state simulation model, pressure and displacement data during the pressing process are collected in real time to predict future state changes. The temperature of the pressure head and coil is introduced as compensation quantities to construct a multi-objective optimization function and dynamically adjust the control strategy to achieve the objectives simultaneously.

Benefits of technology

Under dynamic disturbances, the target clamping force and target termination position can be reliably synchronized, improving the stability and control accuracy of the motor coil pressing process and enhancing the product consistency of drive motors for new energy vehicles and motors for household appliances.

Abstract

The invention discloses a motor coil press fitting process parameter self-adaptive regulation and control method and device, and relates to the technical field of motor vehicle motor manufacturing. The method comprises the steps that press fitting target parameters including a target termination position and target pressing force are obtained, press fitting is started, actual pressure and displacement values are collected in real time, a process state deduction model is constructed, whether double targets can be met at the same time when press fitting is finished in a current control mode or not is predicted, and an analysis result is output. If the conditions cannot be met at the same time, the predicted pressure deviation value and the displacement deviation value are taken as optimization targets, a process state compensation value is introduced, a multi-target optimization function is constructed to solve a control target weighting coefficient, a press fitting tail-section hybrid controller is reconstructed, output instructions of a position ring and a force ring are fused, and press fitting is executed. According to the invention, synchronous high-precision control of the pressing force and the termination position under material fluctuation and environmental interference is realized, and the adaptability and stability of coil press-fitting processes of various motors such as a new energy automobile driving motor and a household appliance motor are improved.
