The Research On Movement Control System Based On Network And Application To The Precised Twister

Along with the fast development of the local capital construction, the demand of various solder wire and winding is daily on the increase. But the improvement and exaltation of the processing technology of these products are needed urgently. For example, high accuracy equipments for winding solder wire are needed. Speeding the research on winding technology based on the high accuracy AC servo is staring us in the face.The solder wire should attain the standard provision deflection and pitch by straightening. The continuous deflection and pitch of the solder wire can assure continuous electrical contact, smooth arc characteristic and coherently penetrative welding, and serve wire on the automation welding equipment continuously. The arranging wire based on angle and the constant intertwist tension are foundation.As far as the foreign equipments are concerned, the automation degree is currently high, the automatically rowing line is precise, initiative unwinds, and winding quality is high, but the price is expensive. The domestic equipments are not enough stability about rowing automatically, and the artificial intervention is needed. Majority is passively unwinding, unsteady quality, and low efficiency.The main contents of this research are about the movement control based on the network, to communicate every examination and performance organization with control center by the fieldbus. Aiming at the machine structure characteristics, the arranging wire mechanism based on angle control is put forward to avoid emergence of unwinding and overlapping in this paper. The pay-off mechanism realizes initiative unwinding by constant tension without distorting the solder wire. All of the principal axis electromotor and pay-off electromotor adopt vector type frequency inverter. The technique problem of constant tension and initiative unwinding is worked out. The winding precision and the work efficiency of the equipment are promoted. The actual results show that performance targets meet technological requirements. Weight error is less than 5‰.
