Heason Technology has developed a new range of low-cost Cartesian style gantry positioning systems for pick and place applications in the growing biomedical and laboratory automation market and other industries where medium precision and medium duty robotic handling for assembly or parts sorting is required.

The design is based on Heason’s PLA leadscrew actuators which feature an extruded aluminium housing and a robust linear motion guide support bearing system in a compact modular package that allows XY and XYZ positioning systems to be designed and built quickly and effectively. The standard range will accommodate X and Y travel to 300mm with a 75mm travel Z axis.

The microstepping motor driven actuator assemblies can be supplied complete with drives, motion controls, cable management, overtravel and datum switches. Further customisation features can include motor mounted encoders for position verification, handwheels for manual positioning, pick and place grippers, and other fixtures to suit application requirements. The T-slot housings are assembled together using simple clamping nuts that allow the combined actuators to be assembled in almost any orientation. The positioning resolution on each axis is determined by the choice of 1mm or 6.35mm pitch leadscrews and is typically between 5 and 25 microns depending upon the microstepping motor resolution used. Positioning repeatability is specified to 0.025mm on each axis and maximum traversing speeds are up to 50mm/sec.
