The automatic test sorting machine is an efficient and economical material sorting solution, and the process architecture design usually adopts a manipulator to take out materials to be tested from an incoming material tray, then the materials are put into a special instrument testing system for testing, and finally the tested materials are taken out by the manipulator and are respectively put into correspondingly defined material trays.
