JIT Material Supply Retrofit for AMR Production Line at a 3C Electronics Factory

Project Pain Points

• •Manual delivery has inconsistent speed and cannot precisely match the production line's JIT supply requirements.
• •Material inbound/outbound confusion during line changeovers; high risk of mix-ups with multi-SKU, low-volume items.
• •Delivery is high-intensity, repetitive work, making recruitment difficult and staff turnover rates high.
• •No complete records for delivery tasks; material flow nodes cannot be monitored.

Implementation Plan

Deploy DD80/DD150 backpack robots and DL150 lift robots with a cloud-based cluster scheduling platform. Supports on-demand line calls and scheduled cyclic delivery, enables automatic elevator use for inter-floor sample transport, and logs the entire sample workflow.

Quantified Achievements

• ★Reduced production line downtime loss by 90%, on-time material delivery rate 100%
• ★Reduce changeover time for new product materials by 70%, enabling rapid adaptation to flexible, multi-variety, low-volume production.
• ★Replaces over 80% of manual delivery roles, saving 60-80 K in annual labor costs
• ★Eliminated mis-shipments and missing items; significantly reduced product defect rates.
