Abstract

Disclosed is a test apparatus for inspecting displacement or tilting of an actuator for a mobile phone camera. The present apparatus is capable of easily selecting defective goods by measuring displacement amounts of the actuator including lens and inclination by using laser beam. This invention can inspect displacement amount of the actuator and tilting at the same time, be used to the various size of actuators using one test apparatus, and prevent the actuator with moving in the side and upper direction.

Description

technical field [0001] The invention relates to a device for inspecting the displacement and inclination of an actuator used in a mobile phone camera. This inspection device is an inspection device that facilitates selection of unqualified mobile phone camera actuators by measuring the displacement and inclination of the built-in lens actuator. Background technique [0002] A small camera actuator needs to be mounted on a small communication device about the size of a mobile phone. [0003] Figure 16 This is a structural diagram of a conventional camera actuator for a common mobile phone. [0004] Figure 16 The mobile phone camera actuator shown includes: in order to change the magnification of the subject, a lens group (500) composed of a plurality of lenses, a lens seat (550) driven in the direction of the optical axis after the lens group (500) is installed, and a fixed part (600), the leaf spring (650) supported on the fixed part (600) that stretches the lens mount (...
