Development of Automatic Mechanical Control System for Copper Wire Elongation

Copper wire is currently a most widely used conductive material for transmitting various signals. Its size can be produced as small as 0.01mm, particularly in medical health equipments. Although most of the wire elongation process has been automized, it still requires human to thread the wire through tens of die molds in advance, usually taking tens of minutes. To resolve this problem, this paper develops an automatic mechanical control system for wire elongation. The proposed hardware system mainly contain three pneumatic claws that can replace the human hands operation. are designed in the proposed system. The first claw is used to clamp the wire. The second claw fixed in the rotating mechanism is to draw the heated wire. The third claw is used to move the wire going through the die molds. The wire drawing power is generated from the gear connection controlled by the serer motor. The control software is developed by PLC programming. The experimental results confirm that the proposed can work efficiently in terms of robust and rapid performance.
