Abstract

The invention relates to a concentric assembly apparatus and method for linear vibration motor. According to the invention, a pick-up device is used to pick up magnets, and the magnets are concentrically assembled in a center of the counterweight assembly through a working guide, so that a concentric assembly of a reference value meeting requirements of assembling processes can be performed, thereby improving workability and reliability.

Description

technical field [0001] The invention relates to a concentric assembly device and method for a linear vibration motor. Background technique [0002] As a component that uses the principle of electromagnetic force to convert electromagnetic energy into mechanical vibration, the linear vibration motor is mounted on the mobile phone for silent notification. Such a linear vibration motor is disclosed in detail in Patent Document 1, and its structure will be briefly described below with reference to this disclosure. [0003] That is, the linear vibration motor according to Patent Document 1 includes: an armature; a stator; a vibrator; and a spring, wherein the armature includes a coil that generates a magnetic field after introducing a current and a magnet that generates an electromagnetic force with the coil; The stator includes a housing housing in which the armature is accommodated; the vibrator includes a yoke for accommodating the magnet and a weight body arranged outside th...
