Multi-wire cutting machine tension control system based on image processing

Abstract

The invention discloses a multi-wire cutting machine tension control system based on image processing. The multi-wire cutting machine tension control system based on the image processing comprises a cutting wire, main rolls, a wire unwinding roll, a wire winding roll, an wire unwinding and arranging wheel, a guide wire wheel I, a guide wire wheel II, a wire winding and arranging wheel, an upper computer, a man-machine interaction module, an image acquisition card, a data acquisition card, a main roll motor, a wire unwinding motor, a wire winding motor, a row-wire unwinding motor, a wire winding and arranging motor and corresponding coders. Real-time images of the cutting wire are collected by the multi-wire cutting machine tension control system, the tension of a wire discharging net is calculated according to the displacement of the cutting wire and is used as a feedback variable to control the rotating speeds of the wire unwinding motor and the wire winding motor; the wire arrangingmotors are controlled according to the track of the cutting wire, and the wire jumper and the wrong arrangement are prevented. According to the multi-wire cutting machine tension control system basedon the image processing, the manufacturing cost and the maintenance cost of a multi-wire cutting machine can be reduced, the wire arrangement route is shortened, and the reliability of the system is improved.

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 solar silicon wafers, sapphire, silicon carbide and other hard and brittle materials in batches and multiple pieces. Drive the workpiece to feed perpendicular to the moving direction of the wire mesh 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. The multi-wire cutting machine tension control system is the core technology of the multi-wire cutting machine. [0003] The existing tension control technology mainly adopts tension weight or tension pendulum rod, etc., which need to add mechanical parts such as tension hammer, tension pendulum rod, guide wheel, etc. The inevitable wear during operation increases the maintenanc...

Problems solved by technology

[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 maintenance costs; at the same time, the length of wiring increases. Increased size and weight of the cutting machine
