The equipment was designed to operate in a fully automated manner: the operator only fills the vibrating bowls, starts the cycle on the HMI, and the system performs feeding, positioning, and screwing of the components with integrated process control.
Main Project Assemblies
| Assembly | Main Function |
|---|---|
| Steel lower structure | Rigid support with leveling feet and ACM closure. |
| Screwdriver with E/D towers | Controlled simultaneous tightening; quick bit change. |
| Vibratory feeders (screw and LUG) | Continuous dosing of fastening elements. |
| Siemens HMI KTP700 + PLC S7-1200 | Programming of times, counters, and alarms; touch screen with shortcuts for Automatic, Configuration, Manual, and Alarms modes. |
| 220 V electrical panel | 24 V power supply, safety relay, isolator switch, circuit breakers, and industrial switch. |
| Pneumatic panel | Safety valve and regulation of 6–7 bar for cylinders and blowers. |
| OK/NOK discard module | Pneumatic actuator that directs good or rejected parts to color-coded BIN drawers. |
