The body‑in‑white welding station integrates the OCE large electronic card to coordinate the timing and sequencing of multiple welding robots along the chassis line. By receiving position signals from encoders and issuing precise trigger pulses, the card ensures that each weld is initiated exactly when the surrounding components are correctly aligned, preventing distortion and reducing rework. In addition to managing the weld cycle, the card interfaces with the station’s safety PLC, allowing real‑time monitoring of door interlocks and emergency stops, which keeps the work area compliant with occupational safety standards. Operators interact with the system through a human‑machine interface that draws its display data from the same card, providing instant feedback on weld quality, energy consumption, and cycle count. When the line shifts to power‑train assembly, the same card can be repurposed to control torque‑verification tools, linking torque transducers to the central diagnostic network and logging each bolt‑tightening event for traceability. This flexibility makes the OCE large electronic card a cornerstone for synchronising complex automation tasks in modern vehicle manufacturing.
