Tích hợp robot ABB vào dây chuyền sản xuất - Case study

# Tích Hợp Robot ABB Vào Dây Chuyền Sản Xuất - Case Study Dự án tích hợp robot ABB IRB 1600 vào dây chuyền welding tại nhà máy ô tô. ## Thông Tin Dự Án ### Yêu Cầu: - **Welding** 24 điểm hàn/sản phẩm - **Cycle time**: < 45 giây - **Precision**: ±0.1mm - **Uptime**: > 95% ### Equipment: - **Robot**: ABB IRB 1600-6/1.45 - **Controller**: IRC5 Compact - **Welding**: Fronius TPS 320i - **Vision**: Cognex In-Sight 7000 - **Safety**: ABB SafeMove ## Giai Đoạn Thiết Kế ### 1. Layout Planning ``` Station Layout: - Robot reach: 1450mm - Part fixture: 800x600mm - Safety fence: 2000x2000mm - Operator access: Front side ``` ### 2. Kinematics Analysis - **Joint limits** check - **Singularity** avoidance - **Collision** detection - **Cycle time** optimization ### 3. Tool Design ``` Welding Gun Specifications: - Weight: 2.5kg - Reach: 150mm - Cable management: Dress pack - Quick change: Manual ``` ## Programming Strategy ### RAPID Code Structure: ```rapid MODULE MainModule PROC main() ! Initialize InitializeStation; ! Main loop WHILE TRUE DO WaitForPart; PickupPart; WeldSequence; PlacePart; ENDWHILE ENDPROC ENDMODULE ``` ### Welding Sequence: ```rapid PROC WeldSequence() ! Move to start position MoveJ pWeldStart, v100, fine, tWeldGun; ! Start welding SetDO doWeldStart, 1; ! Weld path MoveL pWeld1, v50, z1, tWeldGun; MoveL pWeld2, v50, z1, tWeldGun; ! Stop welding SetDO doWeldStart, 0; ENDPROC ``` ## Integration Challenges ### 1. Timing Synchronization **Problem**: Robot và conveyor không sync **Solution**: ```rapid ! Wait for conveyor signal WaitDI diConveyorReady, 1; ! Start robot motion MoveJ pPickup, v200, fine, tool0; ``` ### 2. Vision System Integration **Problem**: Part position variation **Solution**: ```rapid ! Get vision data GetVisionOffset nXOffset, nYOffset, nRotOffset; ! Apply offset pPickupActual := Offs(pPickupNominal, nXOffset, nYOffset, 0); ``` ### 3. Safety Implementation **Problem**: Operator access during operation **Solution**: - **Light curtains** at entry points - **SafeMove** reduced speed zones - **Emergency stops** accessible ## Performance Results ### Before Automation: - **Cycle time**: 120 seconds - **Quality**: 85% first pass - **Operator**: 2 người - **Downtime**: 15% ### After Robot Integration: - **Cycle time**: 42 seconds ✅ - **Quality**: 98% first pass ✅ - **Operator**: 1 người ✅ - **Downtime**: 3% ✅ ## Lessons Learned ### 1. Planning Phase: - **Simulation** trước khi install - **Mock-up** testing quan trọng - **Operator training** từ sớm ### 2. Programming: - **Modular** code structure - **Error handling** comprehensive - **Documentation** chi tiết ### 3. Maintenance: - **Preventive** maintenance schedule - **Spare parts** inventory - **Remote monitoring** setup ## ROI Analysis ### Investment: - Robot system: $80,000 - Integration: $30,000 - Training: $10,000 - **Total**: $120,000 ### Savings/Year: - Labor cost: $60,000 - Quality improvement: $25,000 - Productivity gain: $40,000 - **Total**: $125,000 **Payback period**: 11.5 tháng ✅ ## Recommendations ### For Similar Projects: 1. **Start** với simulation 2. **Involve** operators từ đầu 3. **Plan** cho maintenance 4. **Document** everything 5. **Train** thoroughly Ai đã làm robot integration?
