These systems are used in high-speed pick-and-place, automated assembly, vision inspection, dispensing stations, and high-accuracy inspection.
Linear Motor/Linear Encoder/Air-Bearing Design
Aerotech's high-performance BLM series brushless linear servomotors drive the ABG10000 to speeds of 1 m/s and accelerations of 0.5 g. Feedback is from a rugged noncontact optical linear encoder. The ABG10000 incorporates an active preload on both vertical and horizontal surfaces. The opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air-bearing surface that distributes the load over a large surface area, results in a stage with outstanding stiffness that is ideal for heavy or offset loading. Proprietary manufacturing techniques result in a stage with unsurpassed geometrical characteristics. The air bearing has an inherent averaging effect that maximizes performance. The thin film will fill small surface voids and allow for other irregularities. This characteristic yields superior pitch, roll, yaw, straightness, and flatness specifications.
Rugged Design
Since the linear motor is a noncontact device, there is no backlash, wear, or maintenance with which to contend. The air bearings are magnetically preloaded and assembled to provide optimized stiffness and load distribution.
Cable Management System
Extensive R&D has resulted in an optimized cable management system (CMS) that has been field-proven to be the industry's most reliable design. Large bend radii and high-flex cables ensure that the Air-Bearing Gantry provides millions of cycles of maintenance-free operation. In the unlikely event of a component failure, a modular design ensures that part replacement is fast and easy. All customer 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, greatly simplifying final machine integration.
Turnkey Operation
