Semi-Automatic Assembly Machine for Automotive Control Valve Components

Designed and supported the implementation of a semi-automatic assembly machine for automotive control valve components. The machine used a curved rail transport system with 22 carriers mounted on a timing belt driven by a servo motor or indexing unit. Most materials were supplied by bowl feeders, with sensors used to detect material presence and feeding status. Each bowl feeder was equipped with a hopper to provide approximately one hour of material supply. Due to the soft and flexible characteristics of the rubber component, one operator was assigned for manual rubber loading. The system used a Siemens S7-1500 PLC for machine control and an Advantech IPC for data management. The design focused on stable transportation, reliable feeding, accurate detection, and efficient integration of manual and automated operations.
