The AGS1500 Series Cartesian linear-motor gantry, designed for ultraprecise, high-dynamic contouring, provides precision micromachining, stencil cutting, fuel-cell manufacturing, solder-ball placement, printed electronics, high-speed pick-and-place, automated assembly, vision inspection, dispensing stations, and high-accuracy inspection.
The unit’s planar design minimizes dynamic pitch errors at the work point and keeps the linear motors and linear encoders to the outside of the work area, making the gantry less susceptible to debris-induced damage.
Brushless linear servomotors drive the gantry to speeds of 3 m/sec and accelerations of 5 g. Dual linear motors and encoders are included on the lower axis for performance and precision. The bearings are preloaded linear motion guides with wiper seals and grease fittings, and are mounted to provide dynamic stiffness and load distribution. The noncontact optical linear encoders offer resolutions to 1 nm when coupled with controllers.
The cable-management system features large bend radii and high-flex cables for millions of cycles of maintenance-free operation. In the unlikely event of a component failure, the unit’s modular design allows for fast and easy part replacement.
All cabling and pneumatics can be routed through the system e-chain. Connectors are provided at the workpiece and at the opposite end of the e-chain.
