摘要： A system for programming and controlling the movement of a probe of a voice coil actuator along a path includes a control module that is mounted on a voice coil actuator. Specifically, the control module is connected to a clock and to an encoder to selectively establish a plurality of sequential positions for the probe. Each position in this sequence is defined by a location on the path (translation and rotation), and a time at the location. More specifically, the control module includes a key pad for inputting data to identify each position and also, there is a display for providing a visual presentation of the data. In operation the plurality of sequential positions specify a work cycle for the probe and the voice coil actuator uses the input data to perform a series of work cycles.

摘要： An electric voice coil actuator includes two coils slidingly mounted on a ferromagnetic housing. The coils, which are connected to each other in most applications, are mounted co-axially for linear reciprocal movement in respective magnetic fields. The north poles of a first pair of magnets are affixed to the housing to create the magnetic fields in which the first coil moves. The south poles of a second pair of magnets are affixed to the housing to create the magnetic fields in which the second coil moves. Alternately, the coils can move in the same magnetic field. Opposing poles of the pairs of magnets are affixed to the housing to prevent magnetic saturation of the housing. The coils are electrically connected to an electric current source to produce magnetic fields that interact with the magnetic fields of the magnets to cause movement of the coils. The electric current source may be electrically connected in parallel to each coil, to cause substantially identical movement of the coils. The coordinated movement of the two coils produces more motive force than one coil. Alternatively, the coils may be electrically connected to separate electric current sources. Employing separate current sources permits using the second coil to oppose the movement of the first coil, to brake the motion of the coils for more accurate positioning of the coils.

摘要： The, present invention is a gripper for use in combination with a machine for repositioning a component. Structurally, the present invention includes a housing formed with a chamber. A fixed-pole housing magnet is positioned inside of the chamber. A pair of grips are slidingly mounted for movement relative to the housing. Each grip is partially contained in the chamber and partially projects from the housing. An electromagnetic coil is attached to each grip. Functionally, the gripper is positioned with an assembly component between the grips. A separate electric current is then passed through each of the electromagnetic coils mounted on each of the respective grips. The electric current causes each electromagnetic coil to generate a magnetic field which interacts with the housing magnet. The interaction between the magnetic fields generated by the electromagnetic coils and the housing magnet creates a force on each grip, causing each grip to move translationally to hold, or squeeze, the component. The machine may then be utilized to reposition the gripper and the component.

摘要： A method for manufacturing a linear voice coil actuator, capable of continuously generating a one hundred kilogram force with less than two amperes of current, requires using a coil for generating an electrical field and an unsaturated permanent magnet circuit for generating a magnetic field. In the method of manufacture, a flat surface of the electrical coil is positioned parallel to a flat surface of the magnet to establish a gap therebetween. Before operating the actuator, when no current is running through the coil, a distance of approximately 0.75 mm is established across the gap. Subsequently, during operation of the actuator, when a current of less than approximately two amperes is driven through the coil, the electrical field generated by the coil interacts with the magnetic field of the magnet to generate as much as a 100 kg force on the coil.

摘要： A controller for a voice coil actuator includes sensors that are connected with the actuator probe to monitor both the linear and angular position of the probe, as well as the axial and rotational forces on the probe. Using predetermined instructions, the probe can be controlled in either an open loop mode or in a closed loop feedback mode, for either static or dynamic operations. For static operations, the axial and rotational forces on the probe can be controlled by referencing set values for the forces which are to be applied to/by the probe. For dynamic operations, in addition to the axial and rotational forces on the probe, the linear and angular movements of the probe can be controlled. In the closed loop mode, linear and angular positions, velocities, and accelerations can be used for control. In its operation, the controller selectively establishes linear and rotational movements and forces for the probe which are useful in accomplishing the wide variety of tasks wherein such forces and movements are required.
