Device for detecting screen meshes

A device for detecting screen meshes comprises a detection table and a reading microscope, wherein an LED lamp and a charge power supply are arranged at the bottom of the detection table; an LED lamp power switch is arranged on the outer wall of the detection table; a frosted glass plate is arranged on the upper end surface of the detection table; and the reading microscope is arranged on the frosted glass plate. According to the device for detecting the screen meshes, the LED lamp at the bottom of the detection table provides a lighting source for the reading microscope through the frosted glass plate, so that the reading microscope can detect the screen meshes under sufficient light rays; and the device is simple in structure and convenient to use, one detection worker can finish the screen mesh detection under the condition that the natural light rays are not sufficient or no auxiliary staff provide the lighting source, the reading deviation of the detection worker due to the fact that the light source is
