Dual-motor moment synchronous control system used for hard-brittle material multi-wire cutting machine

Abstract

The present invention relates to a dual-motor moment synchronous control system used for a hard-brittle material multi-wire cutting machine. The dual-motor moment synchronous control system used for the hard-brittle material multi-wire cutting machine comprises a motion controller, the motion controller controls a plurality of servo drivers and a plurality of motors via buses, and the plurality of motors comprise two spindle motors. The two spindle motors adopt a moment mode to control, the motion controller real-timely obtains the moment control data via an on-site bus and controls the two spindle motors according to the obtained moment control data. The dual-motor moment synchronous control system used for the hard-brittle material multi-wire cutting machine of the present invention enables the synchronism of the dual motors to be improved, solves the synchronous time delay and oscillation problems of the two spindle motors, at the same time, saves the transmission belts, and enables the system noise to be reduced.

Description

technical field [0001] The invention relates to the technical field of motor control, in particular to a dual-motor torque synchronous control system for a multi-wire square cutting machine for hard and brittle materials. Background technique [0002] As an important technical crystal, sapphire can be widely used in military, aviation, consumer electronics and other fields. The application of sapphire has broad prospects, especially in the fields of electronic consumption and LED basic applications. [0003] Since the Mohs hardness of sapphire and silicon carbide is greater than or equal to 9, which is second only to the hardness of diamond, it is a typical hard and brittle material, and it is very difficult to cut. In order to solve this cutting problem, early adopt the form of inner circle, outer circle or multi-knife. Cutting, but its efficiency is low and the loss is large. In the later stage, whether it is cutting single (poly)crystalline silicon or crystal, the multi...

Problems solved by technology

Among them, the motor cascade control part is used to set the parameter information and control mode of the motor, and drive the motor to run according to the parameter information and control mode, output the actual speed or actual position of the motor according to the control mode, and the synchronous controller is used to receive The actual speed or actual position of the motor, and compensate the motion of the motor according to the set speed or set position. It adopts two speed control modes, although the synchronization of the two motors is improved by compensating the motion of the motor , but it still has the problem of control lag
