Camera module testing device

摘要

A camera module testing device for detecting light leakage in relation to a camera module includes a base, a first fixing plate, a second fixing plate, a movable element, a stepping motor, a sliding table, a support mechanism, a board and a power supply module, and a processing unit. The movable element includes a first movable plate, a second movable plate, and a third movable plate. The support mechanism and the camera module are driven to rotate to various predetermined angles. The stepping motor drives movable element, the support mechanism and the camera module to swing a predetermined number times for each predetermined angle. The lens captures an image each time. The processing unit compares an image captured each time with a predetermined image and analyze if there is a problem of light leakage for the camera module.

主权项

1. A camera module testing device, comprising:
a base; a first fixing plate placed on the base; a second fixing plate opposite to the first fixing plate and placed on the base; a movable element comprising:
a first movable plate rotatably connected to the first fixing plate;a second movable plate opposite to the first movable plate, and rotatably connected to the second fixing plate; anda third movable plate connected between the first movable plate and the second movable plate; a stepping motor configured to drive the movable element to rotate relative to the first fixing plate and the second fixing plate; a sliding table rotatably connected to the third movable plate; a support mechanism fixed on the sliding table and configured to support a printed circuit board (PCB), a power supply module, and a camera module attached on the PCB, wherein the power supply module is configured to provide power for the PCB and the camera module; and a processing unit; wherein the sliding table is configured to rotate the support mechanism and the camera module to a plurality of different predetermined angles, the stepping motor drives the movable element, the support mechanism and the camera module to swing a predetermined number of times relative to the first fixing plate and the second fixing plate at each predetermined angle, the lens module captures an image each time, the processing unit compares an image captured each time with a predetermined image, and analyzing if there is a problem of light leakage for the camera module.
