Problems solved by technology

[0003] When the existing LED display screen is tested, the LED display screen is generally placed on a shelf or platform. The shelf and platform are fixed, and only the LED display screen of the same specification can be detected. For LED display screens, it is necessary to remake the shelf, which is a waste of cost and low detection efficiency; and the existing shelf can only detect one side of the display screen and cannot be turned over. To detect the second side, the display screen needs to be disassembled. down, re-fixed, poor detection

Abstract

The invention discloses a display screen detecting mechanism including a bottom board, a first support, a second support, a first rotary motor, a second rotary motor, a mounting frame, a plurality of positioning boards and a plurality of fixing bolts. By arranging the first rotary motor and the second rotary motor on two ends of the mounting frame, the first rotary motor and the second rotary motor can be controlled to drive the display screen on the mounting frame to turn over, so that the turning-over function of the display screen during a detection process is realized. By arranging a transverse first positioning board and a transverse second positioning board and a vertical third positioning board and a vertical fourth positioning board on the mounting frame, the positions of the positioning boards are adjusted for display screens of different sizes and the positioning boards are finally locked with fixing bolts. Therefore, the display screen clamping operation is implemented. The detecting mechanism is applicable to display screens of different specifications. By mounting rubber pads on the positioning boards, a cushion effect can be achieved during display clamping and damage to the display screens during the clamping process is avoided.

Description

Technical field: [0001] The invention belongs to the technical field of display screen detection, and in particular relates to a display screen detection mechanism. Background technique: [0002] The LED display is a flat panel display consisting of small LED module panels. LED displays are generally used to display various information such as text, images, videos, and video signals. LED is a light-emitting diode. It is a diode made of gallium, arsenic, phosphorus, nitrogen, and indium compounds by controlling the display mode of a semiconductor light-emitting diode. When electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes. In order to ensure the display quality, it is necessary to strictly control the flatness of the entire LED display, the pixel center distance deviation of each LED display panel, the horizontal relative misalignment deviation of each LED display, and the vertical relative misalignment deviatio...
