More Information
Summary:The utility model relates to a sorting machine used in semi-conductor processing, in particular to a test clamping mechanism of sorting machine which is composed of a spring plate mechanism and a forced-contract mechanism, the spring plate mechanism comprises a test spring plate retaining rack, and left and right test spring plates arranged on the test spring plate retaining rack, the forced-contract mechanism comprises a cylinder and press blocks driven by the cylinder, the press block is respectively arranged at two sides of the left and right test spring plates. Compared with the left and right double-cylinder driving mechanism, The structure that the single cylinder drives the press block more facilitates the press blocks to keep the same speed and force and keep consistent travel relative to the integrated circuit, besides materials are saved.
