Description
Technical field
The present invention relates to a kind of sorting machine, in particular to a kind of chip testing sorting machine.
Background technique
It to the screening of qualified chip is not completed using Wafer Probe platform at present.Smooth Wafer Probe is by showing
What micro mirror, probe base, workbench, wafer-supporting platform, electrician's system and interface display formed, it completes after its collocation tester to wafer
Electric parameters testing and functional test.For this Wafer Probe platform because of the limitation of its probe and striking mechanism, electrical parameter can only
It is set as two grades (qualified product and rejected product, rejected product beat red dot), electrical parameter does not conform to lower than can only being used as setting target
Lattice product are classified as waste material, and substantial portion rejected product can be classified as next shelves (non-defective unit or middle top grade), and the unreasonable of detection device is made
At the waste and increased costs of product.Secondly, since it is desired that changing wafer manually and calibrating and wafer is flat in operating rate
Face is mobile to need X, Y-axis with dynamic etc. limitation, and leading to it, working efficiency is not high per hour.Again, it is needed after wafer test is complete
It is cut into chip, is possible to will cause the damage of chip in cutting process, needs to screen again two times after cutting, leads to increased costs
It is reduced with efficiency.
A kind of chip testing classifier device people is disclosed in the prior art, Publication No.: 106938255 A of CN, no
Foot place is that feeding will appear the phenomenon that chip is superimposed, to influence rotary disc assembly absorption chip, influence to process
Efficiency.
Summary of the invention
The object of the present invention is to provide a kind of double-station chip testing sorting machines, by the straight shake feeding rail for designing new construction
Road so that chip guarantees the continuity of chip conveying when directly shake feeding track is mobile, and improves detection efficiency.
The object of the present invention is achieved like this: a kind of double-station chip testing sorting machine, including is mounted on workbench
On a pair of of loading assemblies, a pair of of test suite, rotary disc assembly, push component and a pair of of Riving Box；
