High-precision printing screen detection device

The invention belongs to the field of detection devices, and particularly relates to a high-precision printing screen detection device, which solves the problems of poor detection accuracy and small detection range in the prior art, and comprises a device base, a side plate is fixedly connected to the top of the device base, and two symmetrically arranged lifting slide rails are mounted on the side plate. A lifting seat is arranged on the lifting sliding rail, a lifting plate is fixedly connected to one side of the lifting seat, through the arrangement of a cleaning brush and other structures and the flexible design of a telescopic air cylinder, an adjusting bolt and a fixing claw, rapid fixing and unlocking of screen plates of different sizes are achieved, the clamping flexibility is improved, and meanwhile, the clamping efficiency is improved. By means of the lifting sliding rail, the servo motor, the cleaning brush and other components, automatic cleaning of the surface of the screen plate is achieved, dus
