Abstract
Copper wire is a major conduction material that carries a variety of signals in industry. Presently, automatic wire elongating machines to produce very thin wiresare available for manufacturing. However, the original wires for the elongating process to thin sizes need heating, drawing and then threadingthrough the die molds by the manpower before the machine starts to work. This procedure repeatsuntil the wire threads through all various die molds. To replace the manpower, this paper aims to develop an automatic wire die molds threading system for the wire elongation process. Three pneumatic grippers are designed in the proposed system. The first gripper is used to clamp the wire. The second gripper fixed in the rotating mechanism is to draw the heated wire. The third gripper is used to move the wire for threading through the dies mold. The force designed for drawing the wire can be adjusted via the gear ratio. The experimental results confirm that the proposed system can accomplish the wiredies mold threading processin term of robustness, rapidness and accuracy.

Summary
Automation on demand for all technical processes is essential in industry. The variety of desired functionalities makes the automation system extremely varied. The modern automation systems are moving towards very high complexity. A high degree of automation increases requirements in measurement technology and goes on in automation technology such as closed-loop and open-loop control or others. Feasible application-specific methods for signal measurement to master future systems are indispensable [1–6]. The wire threading through the die mold for theelongation process has not been automatizeduntil now [7–10]. For advanced automation study related to this issue, many papers can be found in the literature [11–18]. The design of wire die mold threading automation can be regarded as a new technological development in the copper wire manufacturing discipline
