As smart car keys become increasingly sophisticated (e.g., BLE communication, NFC interaction, key force sensing, static current management), their end-of-line (EOL) assembly and testing require higher precision and efficiency. This solution, designed for the HongQi E702 smart key project, flexibly retrofits existing production lines with multi‑station automated testing and assembly tooling. It covers the entire process from housing assembly, key force testing, static current measurement, to BLE RF performance verification.

The system supports quick changeover, tooling error‑proofing, MES data upload, and NFC UID traceability, ensuring consistency and reliability in mass production. By introducing advanced features such as proportional valve control, vision inspection, and shielded test boxes, it significantly improves test accuracy and capacity flexibility – making it ideal for high‑volume EOL applications of premium automotive smart keys.
