Positioning Stage Provides Two Axes of Coordinated Motion
The single rail positioning stage H-gantry design is an open frame XY positioning system. It has two bottom parallel axes with one cross axis connecting the two (H-gantry).
Each linear axis uses brushless linear motors (BLDM-B04), and each has a total stroke length of 25.67 in.; can generate 6.2 lb. of continuous force and 18.7 lb. of peak force, or a combined 12.4 lb. continuous force and 37.4 lb. of peak force on the bottom axis. The non-contact 1-micron resolution encoders allow for precise positioning. The moving tables are guided by a precision recirculating linear ball bearing system.
The linear axes are assembled on a single piece of aluminum extrusion, thus reducing the overall weight of the system. The top cross axis is mounted to the bottom parallel axis using rigid aluminum extrusions, 90-deg. right angle gussets, and custom extrusion end plates. The system is mounted to a flat aluminum tooling plate base. There are also provisions that allow customer cables to be routed within the cable carriers. It has end-of-travel rubber bumper stops.
Additional options include, a home positioning sensor, end-of-travel-sensors, and custom mounting holes. Single extrusion length of up to 6 m long, allows for longer stroke applications.
Features:
- low system weight
- built using standard extrusion profiles
- cable carriers to route payload cables
- three axis of coordinated motion
