The invention discloses an intelligent material conveying device used in a circuit board production line. The device comprises a first material machine and a second material machine. A conveying pedestal is arranged between the first material machine and the second material machine, and a pair of shaft brackets are fixed to the conveying pedestal. A roller lead screw is installed in the shaft brackets in an inserted mode, a feather key is arranged on the roller lead screw, and the two sides of the pair of shaft brackets are each provided with a pair of auxiliary frames. An auxiliary shaft is arranged on each pair of auxiliary frames in an inserted mode. A walking platform is installed on the auxiliary shafts and the feather key together, a material frame is arranged on the walking platform, and a driving component is arranged on the outer wall of the shaft frame. According to the intelligent material conveying device used in the circuit board production line, effective braking is conducted by using feeler levers and pressure sensors, manual work is not needed for controlling and stopping, and the device is convenient and rapid.
