Document Type: Intelligent Manufacturing Upgrade Roadmap for DINGPRECISION (Foshan Dingyi Industrial Technology Co., Ltd.)
Scope: Robotization and digitalization transformation of five core processes: spraying, welding, bending, cutting, and stamping
The sheet metal processing industry has long faced the "Three Highs and One Low" dilemma:
表格
Pain Point | Details | Impact |
|---|---|---|
High Labor Cost | Shortage and aging of skilled welders, sprayers, and bending operators | Recruitment difficulty, retention issues, annual labor cost increases |
High Quality Variation | Manual welding/spraying relies on experienced workers' feel | Inconsistent batch quality, customer complaints, rework |
High Safety Risk | Spraying VOC, welding arc, bending pinching hazards | Workplace injury risks and environmental compliance pressure |
Low Efficiency Improvement | Standalone operations, manual loading/unloading, slow mold changes | Capacity bottlenecks, unstable delivery schedules |
Stable Quality: Robot repeat positioning accuracy ±0.02mm, welding/spraying consistency far exceeds manual operation
Efficiency Improvement: Automatic loading/unloading + robot operation, single-shift capacity increase of 30%-50%
Compliance and Safety: Smart spraying meets GB 14444-2025 explosion-proof and ventilation interlock requirements, reducing personnel exposure
Sheet metal processing intelligence is not "buying a few robots" but a three-layer progression of "Equipment Automation + Production Line Flexibility + Management Digitalization":
Layer 1: Standalone Automation (Robot Workstations)
↓
Layer 2: Production Line Flexibility (Automatic Loading/Unloading + Robots + Online Inspection)
↓
Layer 3: Management Digitalization (MES/ERP/PLM/Data Collection)
↓
Layer 4: Intelligent Decision-Making (Digital Twin + AI Scheduling + Quality Prediction)
DINGPRECISION recommends a phased approach: "Start with single points, then connect lines, then move to the cloud" to avoid the risk of trial and error from one-time large investments.
Spraying is DINGPRECISION's core process (dual-spray dual-coating) and the area with the greatest transformation value.
Plan A: Reciprocating Automatic Spraying Machine (Entry Level)
Applicable: High-volume, regular-shaped sheet metal parts (e.g., energy storage cabinet panels, home appliance housings)
Configuration: Reciprocating machine + automatic gun adjustment system + online film thickness inspection
Advantages: Moderate investment, spray uniformity far exceeds manual operation, suitable for dual-spray dual-coating primer/topcoat layers
Plan B: 6-Axis Spraying Robot (Advanced)
Applicable: Irregular parts, multi-variety small batch production (e.g., robot housings, medical device enclosures)
Configuration: ABB/KUKA/FANUC/Yaskawa spraying robot + offline programming + automatic color change system
Advantages: High flexibility, covers complex curved surfaces, fast color change, suitable for multi-variety production
Plan C: Smart Spraying Line (Full Process)
Process: Pretreatment (automatic zirconium conversion coating line) → Primer robot spraying → Flash-off → Topcoat robot spraying → Baking → Online inspection
Key Configurations:
Automatic gun adjustment system: real-time adjustment of spray pattern, atomization, and flow rate
Online film thickness inspection: laser thickness measurement/eddy current thickness measurement, real-time feedback closed loop
Explosion-proof design: configure explosion-proof area, ventilation interlock, combustible gas monitoring per GB 14444-2025
Robot explosion-proof spraying version: meets explosion-proof zone operation requirements
Smart Spraying Core Benefits: Dual-spray dual-coating process parameters (primer 20-30μm, topcoat 40-60μm, baking 120-180°C) precisely controlled by the system, film thickness consistency improved from ±15% to within ±5%.
Welding is the most labor-intensive process in sheet metal processing with the most significant quality variation.
Plan A: Welding Robot Workstation (Standalone)
Configuration: 6-axis welding robot + positioner + torch cleaning and wire cutting mechanism
Applicable: Stable batch structural parts (energy storage cabinet frames, lift table frames, cabinets)
Programming Method: Teach programming (entry) → Offline programming (advanced)
Plan B: Vision-Guided Welding (Advanced)
Configuration: Laser vision seam tracking system (e.g., FANUC iRVision, KUKA Vision)
Capability: Automatic weld seam position identification, real-time deviation correction, adapts to workpiece tolerance variations
Applicable: Scenarios with significant welding deformation or unstable assembly gaps in sheet metal parts
Plan C: Smart Welding Production Line (Full Process)
Process: Automatic loading → Robot spot welding/arc welding → Visual seam inspection → Automatic unloading
Key Configurations:
Offline programming software (RobotStudio, RoboDK): shortens changeover time
Welding parameter database: automatic parameter matching by material type (stainless steel 304/316, aluminum 6061, cold-rolled steel) and plate thickness
Online seam inspection: laser profile scanning, detects weld height, width, and porosity
Smart Welding Core Benefits: Welding pass rate increases from 95% (manual) to 99%+, consistent weld seam quality, welders transition from "operators" to "programmers and maintenance personnel."
Bending is a key forming process in sheet metal processing. Manual bending relies on experienced workers, with slow mold changes and precision variations.
Plan A: Bending Robot Loading/Unloading
Configuration: 6-axis robot + press brake (e.g., Amada, Trumpf) + automatic tool changing system
Capability: Robot automatically picks up material, positions, bends, and stacks, enabling unmanned bending
Applicable: Stable batch sheet metal parts (energy storage cabinet doors, equipment housings)
Plan B: Bending Angle Online Inspection
Configuration: Laser angle sensor + closed-loop feedback
Capability: Real-time bending angle detection, automatic springback compensation, precision up to ±0.1°
Applicable: High-precision sheet metal parts (medical device enclosures, precision cabinets)
Plan C: Smart Bending Center (Full Process)
Process: Automatic loading → Bending robot → Angle online inspection → Automatic unloading and stacking
Key Configurations:
Automatic tool changing system: tool library + automatic tool change, changeover time reduced from 30 minutes to 3 minutes
Bending program library: call bending sequence and parameters by product model
MES integration: automatic work order issuance, automatic program call
Smart Bending Core Benefits: Tool change time reduced by 90%, bending precision stabilized at ±0.1°, significantly improved flexibility for multi-variety small batch production.
Laser cutting is the "first process" in sheet metal processing and the most automated stage.
Automatic Loading/Unloading: Material storage + automatic loader + cutting machine + automatic unloader and sorter
Nesting Software: CypCut, Lantek, etc., automatic nesting, material utilization rate improved by 5%-10%
Unmanned Cutting: Overnight unattended operation, cutting machine + automatic loading/unloading + automatic sorting
MES Integration: Automatic work order issuance, automatic cutting program call, scrap material management
Stamping Robot: Automatic feeding + stamping + stacking, replaces manual loading/unloading
Servo Press: High precision, low energy consumption, programmable
Die Management: Die library + automatic die change, shortens changeover time
