Pneumatic Actuated Machines That Play a Key Role in Smart Manufacturing

On the electronics production line, the smart pneumatic automatic assembly machine used for assembling switch modules is a typical application of a pneumatic air-operated machine.

The neatly arranged parts in the hopper are first transported to the conveyor track by a pneumatic vibratory feeder or a feeding cylinder. When a part slides into the assembly position, a limit sensor detects that the part is in place and sends the signal back to the PLC system. Then, a pneumatic fixture driven by a double-acting cylinder gently clamps the part, securing it in the precise position. Once the part is correctly positioned, an optical sensor triggers the pneumatic stamping cylinder to operate, pushing the punch to accurately insert the switch module into the plastic housing. The PLC controls the entire sequence of actions: first clamping, then stamping, holding the pressure for a certain time, and finally retracting slowly.

After assembly, sensors automatically inspect the assembled components to confirm whether the switch module is fully in place.

Pneumatically Actuated Machine: A more complex integrated pneumatic system

A pneumatic machine is not a pneumatic device that performs a single action or function. Instead, it can carry out more complex and diversified system operations and functions, often involved in the processing or manufacturing of a finished product. The associated commands and mechanical actions are usually also diverse. For example, the automatic assembly of switch modules requires multiple pneumatic actuators and various sensors for state and position detection, all of which need a control system to coordinate.

By combining multiple pneumatic devices with control logic, a pneumatic machine can form a complete operational workflow. Its components include:A more complete set of pneumatic handling preparation components includes multiple pneumatic elements or actuators, centralized solenoid valves for more effective distribution and control of large volumes of compressed air, and more efficient transmission piping and sealing accessories.
