Process Steps
Feeding: Vibratory bowl/Carrier tape; Insertion: AI vision + laser dual-positioning (Source: Zhuomai); Crimping: Four-point crimping (Source: ZEUEE); Inspection: CCD detection for burrs, deformation, and exposed copper (Source: Aisitong); Assembly: Housing insertion/Heat-shrink tubing application (2–8 cores; Source: Zhuomai)—Process: Feeding → Insertion → Crimping → Inspection (Full closed-loop process).
IV.
Selection Criteria
1. Connector type (Automotive/Telecom/Consumer); 2. Precision (±0.02mm); 3. Cycle time (Units/hour); 4. Inspection (CCD/AI); 5. Compatibility (Multi-specification)—Selection: Type + Precision + Cycle time (Submit samples for prototyping first).
V. Supplier Evaluation
Key factors include: Case Studies (major automotive wiring harness manufacturers); In-house R&D (self-produced pins and sockets; Source: Kereixi); Inspection (100% CCD); Data (cloud-based quality storage; Source: Aistone); and After-sales Support (local service)—Evaluation criteria: Case studies + In-house R&D + Inspection capabilities (avoiding “black box” solutions; Source: Ruizhi).
VI.
Trends
AI Vision: Deep learning-based defect recognition (Source: Aistone); High-speed Interconnect: Connectors for AI servers (Source: Minjiang); Multi-core: Fully automated processing for 2–8 core sheathed cables (Source: Zhuomai); Data Traceability: Unique profiles for every product (Source: Aistone);
Modularity: Independent start/stop for processing steps (Source: Aistone)—Key trends: AI + High-speed + Modularity (80% reduction in defective product outflow).
VII. Procurement Recommendations
Recommendations: Choose ZEUEE for automotive connectors; Minjiang for high-speed interconnects; Aistone/Zhuomai for wiring harness processing; focus on acceptance criteria (pin precision + CCD detection rate);
and prioritize prototyping (small-batch validation first)—Connector production lines: ZEUEE (automotive) and Minjiang (high-speed) (±0.02mm precision + dual verification via CCD).
