The voice coil motors are mainly used in the following applications:
One, the field of optical system
The voice coil motors and linear motors are widely used in the field of optics, microelectronics and measurement of the optical scanning, positioning, aiming, tracking and stabilization of the lens or mirror to carry out precision motion control. For example, the auto focus of video cameras, digital cameras and microscopes, the Z-axis dynamic focusing of laser cutting equipment, the focusing and tracking of optical disk drives, as well as the polarization control of fast mirrors in astronomical telescopes, and so on.
Two, semiconductor equipment field
Semiconductor manufacturing and packaging process, most of the occasions need high-speed and high-precision motion control. The excellent characteristics of voice coil motors can precisely meet these needs. In the dispenser, lead bonding machine, PCB drilling machine, photolithography machine, wafer pick and place and component testing equipment are used.
Three, the field of vibration control
One is used as a vibration source, i.e., excitation equipment. Electrodynamic shaker is the implementation of vibration and shock testing, for mechanical structure dynamics testing, fatigue testing of commonly used equipment, generally small shakers are used in permanent magnet type, and larger shakers (i.e., vibration table) are used in excitation type.
The other is used as a vibration damper, i.e., to eliminate the adverse effects of vibration. Electrodynamic vibration absorbers can be used to absorb the vibration energy of a vibrating system by actively applying appropriate damping forces to counteract or reduce the excitation force, thereby reducing or isolating the transmission of vibration.
Four, linear compressors and control valves in the field
Linear compressors in the use of linear motors to drive the piston directly after the composition of the piston can be eliminated due to the traditional reciprocating compressor piston and the cylinder body of the lateral force caused by the wear and tear, vibration and noise, is widely used in the refrigerator, Sterling refrigeration equipment, etc..
The voice coil/linear motor can also be used for precision control valves in industrial and medical equipment, such as automobile engine valves, electro-hydraulic servo valves, auxiliary respiratory pressure control valves and blood circulation auxiliary pumps.
Fifth, the field of machining
Ordinary lathes can only process circular cross-section of the rotary parts, for some parts with non-circular cross-section is very difficult to process out. The use of large thrust linear motor directly drive the tool for radial high-frequency reciprocating motion, you can realize the non-circular cross-section shape parts processing.
At present, the linear motors and voice coil motors independently developed and produced by Tongmao Linear Motor have been applied in the machining of cams, mid-convex elliptical pistons, and the outer ring raceways of flap bearings, as well as in the laser cutting machines and electromagnetic presses.
Six, other fields
Other fields also have a lot of applications, such as 3D printing, plotter; some need to tension (or pressure) control and displacement / force control of mixed applications, such as wire winding machines, ultrasonic welding, etc..
In summary, linear motors and voice coil motors have a wide range of applications. Kunshan Tongmao motor in the linear in the voice coil motor and linear motor field has many years of research and development experience, has formed a complete range of specifications and models of the series products, in the linear platform has also achieved good results in research and development and application, please pay more attention to our voice coil motor.
