A Tension Control System of Multi-Wire Cutting Machine Based on Image Processing

Abstract

A multi-wire cutting machine tension control system based on image processing, including cutting wire, main roller, pay-off roller, take-up roller, wire discharge reel, wire pulley I, wire pulley II, wire take-up and discharge pulley, upper computer, Human-computer interaction module, image acquisition card, data acquisition card, main roller motor, pay-off motor, take-up motor, pay-off and discharge motor, take-up and discharge motor and corresponding encoders. The multi-wire cutting machine tension control system collects real-time images of the cutting line, calculates the wire mesh tension according to the displacement of the cutting line, and controls the speed of the pay-off motor and the take-up motor as a feedback amount; controls the wire arranging motor according to the cutting line trajectory, Prevent jumper wires and misalignment. The invention can reduce the manufacturing cost and maintenance cost of the multi-wire cutting machine, shorten the wiring path, and improve the reliability of the system.

Description

technical field [0001] The invention relates to a tension control system of a multi-wire cutting machine. Background technique [0002] The multi-wire cutting machine has the function of cutting hard and brittle materials such as solar silicon wafers, sapphire, and silicon carbide in batches and in multiple pieces. Drive the workpiece to feed perpendicular to the direction of wire mesh movement to complete the cutting task. During the cutting process, the cutting wire web needs to run at high speed while maintaining a given tension, so the requirements for the automatic control system are very strict. Multi-wire cutting machine tension control system is the core technology of multi-wire cutting machine. [0003] The existing tension control technology mainly adopts tension weights or tension pendulum rods, which need to add mechanical components such as tension hammers, tension pendulum rods, and guide wheels. The inevitable wear and tear during operation increases mainten...
