Robot Intelligent Cutting System Based On Motion Control Card

At present, the glass cutting system used by domestic glass deep processing enterprises were nearly imported from Italian Bottero and Austrian Lisec. This robot control system was developed to achieve domestic market of certain equipment.An open modulation robot control system solution based on PC and motion control card was proposed, and the close-loop consists of motion control card and AC servos so that on-line programming and motion control are parallel processed.A displacement resolution match algorithm was proposed, and the third axis which controls a cutting wheel remains tangent to the motion of the selected pair of axes by revising the real output pulses of one axis, and curve's cutting with three axes coordinated motion was achieved.An intelligent search-cutting algorithm was proposed by using laser searcher to seek three border points of two legs of glass, and the graphs based on glass plane was mapped to the machine coordinate system through coordinate transformation so that glass search-cutting was implemented.An intelligent robot protection system was proposed by using the sensor on the bottom of cutter to achieve down protection, and by using infrared to protect the safe area, and by monitoring the warning signals of servos, and by using tertiary position limit protection so that both safety and stability of the system were practically enhanced.The cutting system based on this thesis achieves the cutting speed of 120 meter/minute, and cutting precision of +/-0.2mm, and cutting thickness of 2mm-19mm, and the technical specifications above mentioned have nearly reached the level of Bottero, and it occupies great superiority in manufacture and maintenance cost so that it achieves domestic market introduction and enough affirmation of customers.
