METHOD TO ASSEMBLE COIL AND ELASTIC PLATE OF VOICE COIL MOTOR ASSEMBLY

摘要

An assembling method of a coil and an elastic plate of a voice coil motor assembly includes a coil support, a coil wound on the coil support, and two opposing lower elastic plates disposed on an upper part of the coil support. The outer edge of an upper flange of the coil support has at least two opposing protrusions which are arranged radially. The coil has a head end and a tail end which are respectively wound on the two protrusions. The two lower elastic plates are respectively connected with the coil wound on the two protrusions by welding. To prevent the head end from slanting, the lower elastic plates are mounted on the coil support through the operation of an automation apparatus to be soldered with the coil wound on the protrusions.

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 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 a 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, the coil having a head end and a tail end which are respectively wound 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 on 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 of the two lower elastic plates and the two protrusions being contact positions of the lower elastic plates and 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.
