Transformer Winding Jig

Jan 2025 – Feb 2025

What?

Designed a custom jig to assist production workers in wrapping wire around transformer cores accurately and efficiently

How?

  • Designed a jig that elevates and secures the core, enabling smooth wire threading from both the top and bottom
  • Integrated a telescopic end holder to anchor wire at a precise distance for consistent length control
  • Iterated on multiple prototypes to resolve issues with holder stability and fork height
  • Added adjustable levelers to accommodate multiple core sizes
  • Fabricated components using 3D-printed PLA, repurposed materials, and scrap wood to minimize cost

Result

  • Reduced wrapping time from 20 minutes to 15 minutes per unit
  • Improved repeatability and ease of use for production workers
  • Enhanced workflow efficiency for a time-sensitive transformer order
