Abstract
An apparatus for precisely moving and positioning a manufacturing component includes a housing on which a magnet is mounted. An electrical coil is wound around a coil piston which is slidingly mounted on the housing for movement within the magnetic field generated by the magnet. A rod, having a member for gripping the component, is attached for translational movement with the coil piston, and a source of electrical current is connected to the coil which is wrapped around the coil piston. A pneumatic rotary actuator is mounted on the apparatus, and a coupling connects the rotary actuator to the grip for rotation of the grip as desired. A vacuum source can be connected to the grip to allow picking up a fragile workpiece. In the operation of the apparatus, a current is selectively passed through the coil. This current in the coil then moves the coil piston and the attached grip within the magnetic field to position the component as desired in translation. Also, the rotary actuator can be activated to move the grip in rotation as desired. Additionally, position sensors can be mounted on the apparatus to determine the location of the coil piston, and a controller can be incorporated in the apparatus to use this position determination for controlling movement of the coil piston and the attached grip in translation and rotation.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
