Double-flow channel unit device of QFN (Quad Flat No-lead Package) integrated circuit testing separator

Abstract

The invention relates to a double-flow channel unit device of a QFN (Quad Flat No-lead Package) integrated circuit testing separator, which is characterized by comprising a large bottom board (1), a separating flow channel large bottom board (20), two sets of main flow channel assemblies, two sets of testing flow channel assemblies, two sets of bent flow channel assemblies, two sets of shuttle flow channel assemblies, two sets of buffering flow channel assemblies and two sets of separating flow channel assemblies, wherein the large bottom board (1) is vertically arranged, and the separating flow channel large bottom board (20) is arranged below the large bottom board (1) to form an obtuse angle with the large bottom board (1). When entering flow channel units No.1 and No.2, products drop by dead weight, the test is started when the products drop to testing flow channels, and then the products drop to bent flow channels after being tested, slip into buffering flow channels through shuttle flow channels and finally enter feed tubes through separating flow channels. The two sets of flow channels are parallel to each other and independently and simultaneously work so that the speed is improved, and when materials are blocked in one flow channel, the running of the other flow channel can not be influenced.

Description

(1) Technical field [0001] The invention relates to a testing and sorting machine for integrated circuit series products, in particular to a QFN integrated circuit testing and sorting machine with double channel unit device. It is suitable for testing and sorting of QFN integrated circuit products for communication products with high requirements such as LCD and mobile phones. (2) Background technology [0002] The QFN integrated circuit testing and sorting machine is mainly a mechatronic device composed of many mechanical parts with pneumatic components, stepping motors, optical fiber sensors, etc., and its program control is programmed by an industrial computer. It is mainly composed of six local units including feeding unit, rotating unit, flow channel unit, testing unit, shuttle unit and distributing unit. The traditional test sorter is a single-channel material supply test, and the test speed is relatively slow, while the QFN integrated circuit series product test sort...

Problems solved by technology

[0003] The runner unit is the delivery track for the products tested by the test sorter. The previous test sorter used a single runner to feed the material, and the speed was slow. When the material jammed, the machine would stop running, which would affect the production efficiency.
