Automatic test fixture, infrared remote control detection system and infrared remote control detection method

The invention discloses an automatic test fixture, an infrared remote control detection system and an infrared remote control detection method. The automatic test fixture comprises a top plate, four linear module units and four module bases for placing modules to be tested, wherein each linear module unit comprises a guide rail, a first sliding block, a second sliding block and a driving mechanism, and the first sliding block and the second sliding block are located on the guide rail and are oppositely arranged; and according to the size of the to-be-tested module, the driving mechanism of each linear module unit responds to a first external signal to adjust the position of the corresponding first sliding block and/or second sliding block, so that the to-be-tested module is placed on the four module bases. According to the embodiment of the invention, to-be-detected modules with different sizes can be detected, the cost of the fixture is effectively reduced, and the fixture has a wideapplication prospect. 本发明
