PCB drying device

The utility model discloses a PCB (Printed Circuit Board) drying device, which relates to the technical field of PCBs, and comprises a device main body and a crawler belt, a first fixed magnet and a second fixed magnet are respectively arranged on one side of the interior of the device main body, and a rack is fixed on the other side of the interior of the device main body. Through the arrangement of the gear, the rack, the rotating shaft, the placing frame, the movable magnet, the clamping plate, the first fixed magnet and the second fixed magnet, during drying, due to the fact that the movable magnet and the first fixed magnet attract each other, the clamping plate is retracted into the containing groove, and then a worker puts a PCB into the placing frame; at the moment, the crawler belt moves to drive the supporting plate and the placing frame to move, so that the PCBs do not need to be turned over and placed on the conveying belt again for drying again, the drying time is greatly shortened, the working e
