The invention relates to a display screen detection tool and a motion platform. The display screen detection tool motion platform comprises a display screen detection tool. The display screen detection tool comprises a tool body with a display screen containing cavity formed on the surface, a light emitting assembly arranged on the bottom of the display screen containing cavity, a detection probe arranged on one side of the display screen containing cavity and a signal connector which is fixed on the tool body and is electrically connected to the light emitting assembly and the detection probe; the motion platform comprises a first installation bottom plate, a first guiding member which is arranged on the bottom plate and is in linkage with the tool body and a third driving member which is used for driving a first guiding member to move along the first installation bottom plate. The detection signal input before the display detection screen is performed through the display screen detection tool, which avoids the manual detection intersection pollution. The motion platform is used for delivering the detection tool, and realizes the automatic transmission during the display screen detection and improves the detection efficiency.
