A fixed support for voice coil motor comprises a coil, hollow plate, opening, structural reinforcement beam, and a plurality of pins. The pins extruding from the hollow plate allows the coil to wind around them. The opening, which locates on the center of the hollow plate, distributes stress concentration around the center. The structural reinforcement beam, which extrudes from an edge of the hollow plate, improves stiffness of the fixed support, thereby allowing the hollow plate to be made thinner.

Fixed support for voice coil motor

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.
