The invention discloses a stitching process equipment automatic device, comprising six devices: a target-shooting machine, a dragging and edging machine, a chamfering machine, a washing machine, a plate thickness measuring machine, and an automatic categorization plate collector, and characterized by comprising a: area programming: programming the area layout of each device together, and leaving no obstructs among connection; and b, employing a conveyer, a conveyor belt, a central positioning machine and a lower trigger among equipment for connection, and allowing the equipment to perform effective transmission connection work. According to the technical scheme, all works can be completed only through placing a plate by the target-shooting machine; the work which requires multiple persons and multiple processes is improved to automatic line production which can be completed by a single person, thereby reducing costs, and increasing efficiency; the stitching process equipment automatic device has a high automation degree, is easy to operate, and can improve work efficiency, reduce production abnormity and manual carrying, decrease scratch discards, and save manpower resources.
