Motion Control – Linear-XYZ-Rotary Combination Stages from Intellidrives!
 |
Philadelphia, PA, — Motion Control Components and Systems – Intellidrives’ compact, high precision XYZ-Rotary stage is a combination of Intellidrives: LSMA XY lead-screw driven stages, an MLVT Lift stage, and an RTHM worm gear rotary table.
Features include:
– XY stroke 100×100 mm
– Lift 13 mm
– Unlimited rotation
XY Lead-Screw Driven Stages – The LSMA miniature linear actuators designed for the space confined applications while retaining the high reliability required in production environments. It is an ideal choice for measurement, testing, alignment and component assembly in any application on the factory floor or laboratory environments.
The precision ball screw or micrometer grade lead screw provide excellent accuracy and repeatability with ultra-fine positioning resolution capability of 0.1 micron or finer when driven by the stepper motor. The servomotor version is equipped with a rotary encoder and provides exceptionally smooth travel.
Lift Stage – The MLVT Vertical Lift Stages offers precise vertical translation for payload elevation. A unique wedge design or direct drive motorized screw converts motor rotation into true vertical elevation of the platform. Precision bearings provide platform stiffness and stability while the screw mechanism assures positioning accuracy.
Rotary Table – The RTHM series rotary stages provide arc-second resolution when driven from a micro-stepping or a brushless servo motor controller. The low profile design is made possible by the use of compact precision bearings. The rotating carriage of the stage provides continuous rotation of load up to 10 kg and has large clear aperture to allow the passage of the optical path or cables directly through the stage. The main body of the stages is made from lightweight anodized aluminum and can attach directly to an optical table or moving linear or XY actuators and can be mounted at any orientation. A precision worm gear assembly is used to transfer the rotary motion of the stepper motor into rotary motion of the carriage. The small size allows use in confined spaces, such as laser cavities, disk texturing machines, manufacturing areas for fiber optical components or semiconductor manufacturing.

XY Gantry Robot with Theta-Control from Intellidrives!
|
Philadelphia, PA, — Motion Control Components and Systems – Repeatability and accuracy are essential characteristics of any motion control system, and the objective of the design is to assure the desired trajectories can accurately follow through the working range of the system.
In traditional XY gantry designs upper gantry member (Y axis) is carried by two identical bottom axes (X1 and X2). Each X1 and X2 axes motor/screw/bearing systems are separated by finite distance orthogonal to the direction of the axes.
INTELLIGENT ACTUATORS can easily “talk over” USB 2.0, Ethenet, RS232, RS485 interfaces and come with powerful yet easy to use software packages. for system start-up and integration, like communication drivers, linkable DLL libraries, National Instruments Labview drivers and VI examples, GUI and easy-to-use DXF conversion software.
Due to the manufacturing precision of the components, such as linear guides deflections, ball screw lead errors, axes misalignment, the variation of the position errors in X1 and X2 axes controllers, XY gantries orthogonality is affected. As Y-axis with load traverses across XY plane, it also introduces X axes position errors that are Y axis position dependent.
The current approach to this design challenge is to implement 2-D position error mapping or suspend Y axis on the flexible members (flexures) and to independently control X1 and X2 axes to assure orthogonality. This approach reduces system bandwidth and provides small range of angle adjustment, usually within not more than 1 degree.
There are also many applications, where large THETA angle is an INTENTIONAL FEATURE of the system design (X-Y-THETA) to allow alignment of the work tool to the non-orthogonally located objects or to align patterns.
