Precision Assembly Automation

Fully Automatic TWS Charging Case Plug Connector Assembly & Inspection Line

This fully automatic line is engineered for the assembly, welding, and inspection of TWS charging case plug connectors. It integrates three core modules — CNC & MESH assembly & welding, CNC & CONTACT assembly & welding, and Frame assembly — into a single continuous workflow. Vision-guided assembly and welding, combined with zero-downtime material changeover, deliver an assembly accuracy of ±0.01mm with welding CT of 1.3 s and assembly CT of 0.8 s.

Product Introduction

Application Scenarios

Industry Focus

Widely used in consumer electronics manufacturing, precision connector assembly, wireless earbud charging case production, and precision component processing.

Applicable Products

Tailor-made for TWS charging case plug connectors and similar precision connectors.

Line Compatibility

Fully automatic production line with vision-guided processes and zero-downtime material changeover.

Core Advantages

  • Vision-Guided Assembly & Welding: High-precision positioning with real-time feedback to PLC and motor compensation ensures assembly accuracy of ±0.01mm, and product assembly of ±0.03 mm, ideal for small, circular-shaped products.
  • Closed-Loop Control System: After assembly, machine vision performs real-time inspection and feeds the results back to the control system for real-time automatic error correction, ensuring every product remains within tolerance and meets Grade-A quality standards.
  • Zero-Downtime Material Replenishment: AGV-based automatic tray switching and automated laser welding of terminal carrier tape enable non-stop material replenishment during operation, significantly boosting Overall Equipment Effectiveness (OEE).
  • High Surface Quality Control: For electroplated CNC parts, where surface quality is critical, the line prevents scratches and shiny marks by automatically cleaning the welding head with CO₂ every 30 minutes.
