An actuator may include a stator supporting a magnet; a stationary pole; and a bobbin supporting a winding of a coil, the bobbin being coaxial with the stator and stationary pole, and positioned inside the magnet and outside the stationary pole. A gap may be provided between the bobbin and the stationary pole. A beam steering mechanism may include a mirror; a frame; a pivot anchor fixed to the frame and connected to the mirror; and an actuator. An output end of the actuator may be connected to the rear surface. A beam steering mechanism may alternatively include a flexure; a mirror attached to the flexure; a frame; supports fixed to the frame and the flexure; a pivot anchor fixed to the frame and connected to the mirror or the flexure; and an actuator. An output end of the actuator may be connected to the flexure.

Actuator and beam steering mechanism using an actuator

An actuator may include a stator, a pole; a bobbin; and windings provided around an exterior surface of the bobbin. The stator may include a stator body; and a plurality of magnets circumferentially arranged around an inner surface of the stator body. The stator, the pole, and the bobbin may be coaxial. An outer diameter of the pole may be smaller than an inner diameter of the bobbin such that the bobbin is movable in an axial direction over an exterior surface of the pole. An outer diameter of the bobbin may be smaller than an inner diameter of the stator such that the bobbin is movable in an axial direction inside the plurality of magnets circumferentially arranged around the inner surface of the stator body.

A laser marking system for marking a predetermined pattern on a workpiece may include a first light source structured to emit first light at a first wavelength; a second light source structured to emit second light at a second wavelength different from the first wavelength and selected to mark a marking surface of the workpiece; beam shaping optics structured to adjust a focal length of the second light; beam steering optics structured to aim the first laser light and the second laser light; a controller configured to control the first light source to emit the first light at the marking surface of the workpiece and control the beam steering optics to aim the second light so as to mark the marking surface of the workpiece and create the first predetermined pattern; and a camera structured to detect first light reflected from the marking surface and record an image.

Laser marking system and method for laser marking a workpiece

An actuator utilizes a voice coil motor with one or more voice coil windings supported on a light weight moveable bobbin that connects at one end to move an object rapidly up to a small number of millimeters translationally along a system axis. The bobbin moves over a distal portion of a center pole of a stator, which supports the voice coil motor magnets. The pole, which acts as a flux path for the voice coil motor, also provides a thin film of air in a gap between the pole and the bobbin via an air path and corresponding holes at the distal end of the pole. The bobbin moves translationally relative to the pole on the thin film of air under the control of the voice coil motor.
