Different Screw Shapes and Sizes

Develop AI-powered vision sensors capable of recognizing and locating various screw shapes and sizes.

Design the screw handling mechanism to adapt to different screw geometries and minimize potential damage.

Detect. Keep going.

Our solution integrates torque monitoring and feedback systems to detect cross-threading or screw head damage during fastening.

Additionally, error-proofing mechanisms automatically halt the process if a cross-threaded screw is identified, preventing scrap and ensuring consistent quality.

Process

Process Overview

1. Operator loads parts into the fixture.
2. Vision AI Sensor validates part presence before beginning.
3. The robot jogs to the screw presenter, automatically picking up screws.
4. Screw passes through a thrubeam area sensor to verify correct height.
5. The robot initiates the fastening process.
6. IX Height Measurement Sensor checks screw head height tolerance.

Process Diagram Flow
