Pressure detector for display screen production and pressure detection method

The invention discloses a pressure detector for display screen production and a pressure detection method, and belongs to the technical field of display screen production, the pressure detector comprises a detection table, a mounting plate is arranged on the detection table, a hydraulic cylinder is arranged at the top of the mounting plate, and a pressing plate is arranged at the output end of the hydraulic cylinder; a plurality of testing mechanisms for detecting the pressure of the display screen are arranged on the inner side wall of the mounting plate at equal intervals; and an adjusting mechanism for adjusting and limiting the display screen is arranged below the displacement testing mechanism on the detection table. According to the invention, the length of the first telescopic spring is adjusted through the telescoping of the first electric control cylinder, so that the pressing column on each testing mechanism applies different pressure to the display screen, and when the hydraulic cylinder moves down
