Moving coil actuator is precise about PCB position
A
SMAC Europe product story
Edited by the Engineeringtalk editorial team
Feb 18, 2008
Accurate actuator is highly cost efficient has now been used in a number and variety of PCB assembly applications across the world.
The SMAC LAR31 series moving coil actuator is extremely precise with an encoder resolution of 5um with standard options of 1, 0.5 and 0.1.
The device is capable of repeatable positioning to +/-2 encoder counts.
Further to this highly accurate placement with maximum shaft run-out of 30um as standard, with 10um achievable for special units.
It also designed to deliver long life for continuous operation, with units in excess of 100million cycles in the field.
The LAR31 series actuator is compact, measuring only 140 x 77.25 x 35mm, and can easily be programmed to control force/torque, position and velocity in all axes.
This enables the ability placement of components at different heights and to have a window to warn of missing or broken components.
The unit offers multiple functions, with the ability to assemble and test components with additional life test and measurement functions in one single unit.
The system has the significant advantage of low repeatable friction.
The actuator also has SMAC's unique "Softland" function, which enables the unit to gently land on a delicate component with a controlled force to avoid damage of both the component and the actuator.
This SMAC solution is highly cost efficient has now been used in a number and variety of PCB assembly applications across the world.
SMAC moving coil actuators are designed to deliver the following benefits: compact overall size, light weight, extremely fast, high precision and offering a combination of programmable force, position and velocity in both linear and rotary axis at the same time.
