Production line yield collecting device

The invention discloses a production line yield collecting device. The production line yield collecting device comprises a rack (1), wherein an electric conveyor belt (2) is arranged below the rack and can be used for conveying a to-be-collected sample; a counting module (3) and an emitter (4) are arranged in the above rack; the emitter (4) is used for emitting conveying information to a computer (5) at a far end; the electric conveyor belt (2) is positioned below the rack and is capable of conveying a to-be-collected object; the counting module (3) is positioned in the rack and is capable of counting the objects which pass through the lower side; the emitter (4) is positioned in the rack and is capable of sending data obtained by counting to the computer (5); the computer (5) can be used for recording and storing the collected data. The production line yield collecting device can be used for collecting objects which quickly pass through, so that the working efficiency is improved, the time is saved, and the automatic yield collection is realized.
