Custom automation cases
Vision-guided automatic screwdriving machine
Electric fan manufacturing ·
A complete machine that identifies screw holes, determines the applicable screw, and performs the fastening cycle through integrated vision, mechanics, PLC control, and a robotic arm.
Challenge
In an electric fan factory, manual screwdriving made it difficult to consistently match each screw hole with the correct screw and introduced fastening defects, including damaged or failed screws.
Constraints
- The system needed to distinguish screw-hole requirements before initiating the fastening operation.
- Customer identity, cycle time, and production performance remain confidential.
PandectAI scope
- 01Design and build the complete automatic screwdriving machine
- 02Develop the machine-vision recognition and screw-selection logic
- 03Integrate mechanical assemblies, PLC controls, robotic arm, and fastening tooling
Solution
PandectAI built the full machine around a vision-guided workflow. The vision system identifies the screw hole and determines the applicable screw; the PLC coordinates the mechanical assemblies, robotic arm, and automatic screwdriving tooling to execute the required fastening cycle.
Build vision and mechanics
Develop recognition, machine structure, fixtures, motion, and screwdriving tooling as one coordinated design.
Integrate and verify
Connect the vision system, PLC, robotic arm, mechanical assemblies, and fastening cycle, then verify the complete machine workflow.
