This utility model relates to the field of automatic screen detection technology, including a
workbench, an automatic screen detection device for LED displays, a
fixed frame, a sliding frame, slidably mounted on the outer wall of a support plate; a placement plate for placing the screen to be tested, fixedly mounted on the top of the
workbench; a contact for touch screen testing, fixedly mounted on the bottom of the placement plate; and a fixing device for clamping the screen, located on the top of the
workbench. The fixing device can switch between a first state and a second state. In the first state, the fixing device fixes the screen on the surface of the placement plate. In the second state, the fixing device engages with the screen on the surface of the placement plate, and a connecting rod pushes the clamping plate and the fixed plate to fix the screen. This allows the contact to move downwards and automatically clamp the screen during testing, achieving simultaneous detection and fixing, reducing manual operation steps.
