Lens drive device and producing method thereof

镜头驱动装置及镜头驱动装置的制造方法

Abstract

本发明要解决的技术问题是以少量加热将板簧与线圈进行连接,防止热量对镜头保持部件的损坏。一种镜头驱动装置(1)的制造方法:在保持镜头体的镜头保持部件(5)的周围安装线圈(59),并设置磁轭(7)及磁铁(6)以便使磁路作用于线圈(59)而使镜头保持部件(5)沿光轴方向移动,在光轴方向上,通过下板簧(4)对镜头保持部件(5)进行支持,并且将线圈(59)的端部卷绕到设置于镜头保持部件(5)上的缠绕销(57)上,在下板簧(4)上形成的切口部(63)的附近,通过焊膏(65)将卷绕在缠绕销(57)上的线圈(59)的端部与下板簧(4)电连接。
The invention aims to resolve a technical problem that a plate spring can be connected to a coil by a little heating and the damage of heat to a lens retaining component can be prevented. A producing method of a lens drive device (1) comprises the steps of installing a coil (59) at the periphery of the lens retaining component (5); arranging a magnet yoke (7) and a magnet (6) to enable a magnetic circuit to act on the coil (59) to make the lens retaining component (5) move along an optical axis. In the optical axis direction, the lens retaining component (5) is supported by a lower spring plate (4), and the end part of the coil (59) is rolled on a winding pin (57) disposed on the lens retaining component (5). Near a notch part (63) disposed on the lower spring plate (4), the end part of the coil (59) rolled on the winding pin (57) is electrically connected to the lower spring plate (4) through a soldering paste (65).
