Abstract
A solder head control mechanism which uses a movable small size and simply structured acoustic coil linear servomotor to directly drive a solder head to perform soldering operation. The solder head links with a position sensor, a controller and a current output actuator to form a closed loop control mechanism which has small inertia, fast response time and great positioning accuracy. The controller may dynamically change amplifying value to actuate the solder head.
