Subject 18: Design and Development of an Automatic Machine for Untwisting and Straightening Conductive Wires PFE

Project overview

• Design and develop an automatic machine capable of untwisting (left-right rotation) and straightening twisted conductive wires.
• Aim to produce a functional prototype with validated performance for cycle time, repeatability, and straightening quality.
• Duration: 06 Months. Number of Interns: 02 Interns.

Main tasks and deliverables

• Complete mechanical design of the system including guiding, driving, holding, and straightening mechanisms.
• 3D modeling and sizing of mechanical and electromechanical components using SolidWorks or Autodesk Inventor.
• Programming of the automatic cycle covering time management, left/right rotation control, safety interlocks and emergency stop.
• Development of a functional prototype and experimental validation (measure cycle time, repeatability, and straightening quality).

Required skills and technologies

• Mechanical design experience (SolidWorks or Autodesk Inventor) and component sizing.
• Industrial automation skills: PLC, API, or microcontroller programming for motion and sequence control.
• Knowledge of sensors, kinematics, and machine safety (safety circuits, emergency stop implementation).

Experimental validation and performance targets

• Implement test plans to evaluate cycle time, repeatability, and straightening quality under representative conditions.
• Data collection and analysis to quantify improvements and identify design iterations.
• Ensure safety validation and reliable emergency-stop behavior during tests.
