Automatic assembly of actuators
An actuator converts an electrical, hydraulic or pneumatic energy source into a linear or rotational movement. Together with sensors, these drive elements are a key component in every machine.
For more than 20 years, Wolf has been manufacturing assembly lines for actuator production, among other things.
These are mostly electric actuators with rotary movements for the automotive sector.
Typical processes in actuator assembly
Several steps are necessary when assembling an actuator. These vary depending on the design of the component. The usual processes are
• Joining / pressing in pins
• Joining components automatically (e.g. stator, rotor, gears, circuit board)
• Greasing
• Heat caulking
• soldering
• Automatic optical inspection (AOI)
• Plastic welding with laser
• Laser marking
• End-of-line tests (EOL) e.g. functional test, noise test or similar
Feeding into the assembly line
The production of actuators involves many assembly tasks. The parts to be assembled must therefore be fed into the system. The small parts can be fed using the following systems:
• Manual via manual workstation (insertion / preloading)
• Stack feeding into pallets
• Blister belt feed
• Magazines
• Vibratory spiral conveyor
• Step conveyor
• Vibration table with image processing for parts recognition (AnyFeeder)
Actuators can be assembled in both fully automated and hybrid assembly lines. At Wolf, the degree of automation of the assembly line can be freely selected. Depending on the framework conditions (quantities, production location, etc.) and individual requirements, we work with you to develop the ideal system concept.
