The invention discloses a plate type production line capable of automatically charging and discharging. The plate type production line comprises a charging platform, a machine body and a discharging platform; the charging platform comprises a lifting platform which is arranged on a base, a shear shank is arranged at the lower part of the lifting platform, and one end of a hydraulic cylinder is connected to the base; the discharging platform consists of a motor, a reduction box, a belt, a stopping bakelite plate, a section frame, an optoelectronic switch and a rolling shaft; the machine body consists of a bed body assembly, a gantry assembly, a charging assembly, a rear locator, a lateral locating system, an X sliding plate assembly, a Z shaft assembly, a dust collection system and a pushing system. The plate type production line provided by the invention has the beneficial effects that manual labor can be reduced greatly, the plate locating precision is higher, the use ratio of plates can be improved, and the production cost can be reduced; furthermore, plates can be pushed to the discharging platform timely after the completion of plate processing, so that time that plates occupy the machine main body, after the completion of processing, can be reduced, and the production efficiency can be greatly improved.
