Control method and control system of servo electric screwdriver

Abstract

The invention discloses a control method and a control system of a servo electric screwdriver. The control method comprises the steps that preset servo parameters of the servo electric screwdriver are configured, and the preset servo parameters are obtained from a database; a controller is started to input preset servo parameters so as to enable the servo electric screwdriver to operate, and a torque value is detected through real-time torque so as to construct a torque curve model; whether the torque value of the torque curve model exceeds a preset range within a preset time or not is judged to obtain a judgment result; a preset servo parameter is adjusted according to the judgment result; and the controller is started to input the adjusted servo parameters so as to enable the servo electric screwdriver to operate, and a torque value is detected through real-time torque so as to construct a new torque curve model. According to the method, the torque curve is constructed according to real-time data of the servo electric screwdriver, and corresponding torque, speed and servo turns are adjusted according to changes of the torque reflection curve so as to make a servo electric screwdriver control strategy; and the screw driving process of the servo electric screwdriver is controllable, informatization butt joint is achieved, full-automatic production is achieved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of a servo electric batch, in particular to a control method and a control system for a servo electric batch. Background technique [0002] The traditional servo electric screwdriver control is to control the servo rotation with a given torque, and there is no feedback on the resistance and friction encountered in the process of servo electric screwdriver rotation and screwing, which cannot accurately reflect the servo electric screwdriver screwing process, resulting in servo electric screwdriver screwing The process is uncontrollable, and there are quality problems of screwing. Contents of the invention [0003] Aiming at one or more of the above problems, the present invention provides a control method and control system of a servo electric screwdriver, which realizes the controllable screw driving process of the servo electric screwdriver, fully automated production, and improves production efficiency. ...
