Precision assembly and inspection station
The core assembly station adopts a closed aluminum profile frame design, equipped with Delta HMI touch screen for intelligent parameter setting and real-time monitoring. This station integrates precision pneumatic pressure devices (with pressure gauge monitoring) for high-precision pressing of critical relay components. Multiple safety protection mechanisms ensure operational safety and production stability. The scientific equipment layout and organized piping reflect modern intelligent manufacturing standards.
Automated material feeding and assembly system
Our fully automatic tray loading system features multi-layer pallet stacking and conveyor mechanisms. This system enables precise positioning and continuous feeding of relay components, with precision servo robotic arms handling automatic grasping and transfer operations. Trays carrying relay products are neatly arranged on the production line, with complete automation from feeding to discharging, ensuring stable production cycles and consistent product quality.
