Claim:
1. A method to assemble a coil and elastic plates of a voice coil motor assembly, comprising the steps of: step 1: winding the coil around a support body on a coil support, the coil support being a sleeve, the coil support having an upper flange and a lower flange at upper and lower ends thereof, and the support body between the upper flange and the lower flange for the coil to be wound thereon, an outer edge of the upper flange having at least two opposing protrusions, radially opposed to each other and protruding in a radial direction, the coil having a head end and a tail end which are respectively wound in one or more loops perpendicular to the radial direction on the two opposing protrusions; step 2: installing the two opposing lower elastic plates on an upper surface of the coil support through an automation apparatus, the two opposing lower elastic plates being respectively stacked above the two opposing protrusions of the coil support; step 3: placing the coil support stacked with the lower elastic plates in a welding apparatus, contact positions between the two lower elastic plates and the two protrusions being an area formed by the one or more loops of the coil for proceeding with solder paste; and step 4: soldering tin on the solder paste or fixing by laser welding to assemble the coil and the elastic plates of the voice coil motor assembly.
