Camera module automatic function test machine

Abstract

The invention discloses an automatic function testing machine for camera modules. The automatic function testing machine comprises a work platform and a controller, at least one rotation testing device is fixedly arranged on the work platform at intervals, and a locating jig and a PC are arranged on the work platform corresponding to each rotation testing device. A plurality of testing units used for carrying out function testing on the camera modules are located on the rotation testing devices. Corresponding movement locating mechanisms are arranged on the work platform corresponding to part of the locating jigs, the controller can control the movement locating mechanisms to push the corresponding locating jigs to move and to be located at set positions, the controller can control the rotation testing devices to rotate by a set angle and to be located, and the testing units on the rotation testing devices are made to be aligned at the camera modules when rotating to the set positions. The automatic function testing machine is simple in testing operation, labor can be greatly reduced, the workload of testing personnel is greatly lowered, testing work efficiency is optimized, meanwhile, testing precision is improved, and therefore the testing cost of a whole test is lowered.

Description

technical field [0001] The invention relates to a camera module image function testing device, in particular to a camera module automatic function testing machine. Background technique [0002] With the development of technology, the demand and quality of camera modules on mobile phones and other electronic products are increasing and stricter. In order to ensure the quality of the product, it is necessary to test the function of the camera module. The function test of the camera module is to place the module under the specified light source and test the test items under the corresponding light source, so as to achieve the purpose of picking out the defective products. . The functional test of the camera module mainly includes: AF close focus test, stain test and AF far focus and MTF far focus test, the functional test of the camera module in the prior art needs to pass through a plurality of devices with different test functions to the camera module Perform multiple funct...

AI Technical Summary

Problems solved by technology

During the test, employees need to manually move the camera module to the corresponding light source to test the function. At this time, the position of the camera module is not fixed, and it is usually impossible to place the camera module in the center of the light source. , the test accuracy is greatly affected by

In addition, because employees have been manually moving modules, a large part of the entire testing process is wasted on moving modules, which seriously affects the efficiency of production testing.
