PCB conveying mechanism and material taking device

The utility model belongs to the technical field of laser cutting, and particularly relates to a PCB conveying mechanism and a material taking device. The PCB conveying mechanism comprises two wall plates which are arranged at an interval; corresponding belt conveying assemblies are respectively arranged on the wall plates and are respectively used for conveying corresponding process edges of a PCB (Printed Circuit Board); a plurality of notches are formed in the positions, located at the grabbing positions, of the wall plate, at least parts of the notches are located on the lower side of the technological edge, and clamping jaws of a grabbing mechanism stretch into the notches to grab the PCBs. The corresponding belt conveying assemblies are arranged on the wall plates of the PCB conveying mechanism and used for conveying the corresponding process edges of the PCBs, the multiple notches are formed in the positions, located at the grabbing positions, of the wall plates, at least part of the notches are locate
