Automated Tape Punch Machine
A complete electromechanical tape punch system — CAD-designed punch-die mechanics, stepper-driven feed, and a hardwired PLC controller for automated hole patterns used in precise rivet insertion.
Overview
As an undergraduate research assistant at Ryerson University, I designed and assembled a mechanical system for tape punching. The machine creates a pattern of holes specially designed for accurate rivet insertion. A gear system driven by a stepper motor feeds the tape, and a guiding and positioning system keeps the tape precise relative to the punch-die. The system was fine-tuned and successfully tested. Alongside the mechanics, I designed, hardwired, and tested a controller for full automation using a PLC, stepper driver, and proximity sensors for tape and punch position feedback.
Key Highlights
Punch-Die Mechanics
Custom mechanical design for accurate hole patterns used in rivet insertion
Stepper Feed System
Gear-driven stepper motor for controlled tape feeding and positioning
PLC Automation
Hardwired PLC controller with ladder logic for the full punch sequence
Sensor Feedback
Proximity sensors for locating both tape and punch position
Mechanical Tape Punch
Designed and assembled in CATIA V5 — stepper-driven feed, guiding/positioning system, and punch-die assembly for precise hole patterns.
Tape Punch Controller
A programmable logic controller was coded to run the automated punching sequence. A stepper motor driver controls tape feed; proximity sensors provide feedback. Power supply, relays, and hardwired schematics complete the industrial-style control box.
