Position movement module of AOI optical testing machine

The utility model belongs to the field of optical testing, particularly relates to a position movement module of an AOI (automatic optical inspection) optical testing machine, and aims to solve the problems that the modules can be fixed and detected only after limiting bearing plates matched with different models of modules are mounted, so that the limiting bearing plates need to be frequently mounted and dismounted during detection, the operation is relatively tedious, and the cost is high. In order to solve the problems that the use convenience is reduced and the detection efficiency is influenced, the utility model provides the following scheme that the device comprises a test frame, a turntable is arranged in the test frame, and a plurality of optical test racks are fixedly mounted at the top of the turntable. When the limiting bearing plate is used, liquid crystal display modules of different models can be conveniently limited and fixed, the modules can be detected without being installed after the limit
