Abstract
A packaged chip detection and classification device includes a rotation unit for transporting a plurality of packaged chips, a packaged chip detection unit, and a packaged chip classification unit. The rotation unit includes a rotary turntable, a plurality of receiving portions formed on the rotary turntable, and a plurality of suction-exhaust openings respectively formed in the receiving portions. Each receiving portion is used to selectively receive at least one of the packaged chips. The packaged chip detection unit includes a packaged chip detection module adjacent to the rotation unit for detecting each packaged chip. The packaged chip classification unit includes a packaged chip classification module adjacent to the rotation unit for classifying the packaged chips. Therefore, the packaged chip detection and classification device can be used to detect and classify no-lead packaged chips by matching the rotation unit, the packaged chip detection unit, and the packaged chip classification unit.
