The invention discloses an NC membrane strip clamping and placing machine. The NC membrane strip clamping and placing machine comprises a plurality of bearing plates connected end to end, an NC membrane strip storing tray, a moving frame and an NC membrane strip clamping mechanism, wherein the bearing plates are used for placing test paper substrates, the NC membrane strip storing tray is used for placing NC membrane strips, the moving frame is used for moving the NC membrane strip clamping mechanism between the bearing plates and the NC membrane strip storing tray, and the NC membrane strip clamping mechanism is used for clamping NC membrane strips and comprises a first clamping plate and a second clamping plate. The stroke of a power air cylinder is set as a fixed value, then primary buffering is formed under the combined action of rotating plates, tension springs and springs, and finally clamping is achieved through elastic pieces controlled by piezoelectric material layers, so that it is ensured that NC membranes can be clamped without damage, and the percent of pass of test paper made with the method is quite high.
