After all data are measured, the electric linear sliding table c2 drives the three-jaw cylinder b2 to move to a blanking station, a clamping jaw of the three-jaw cylinder extends out, a workpiece falls into a blanking frame, and then the electric linear sliding table c2 resets to wait for detecting the next workpiece. In this embodiment, there are two blanking slots in the blanking frame 4, receive certified products and non-certified products respectively, and electric linear sliding table c2 transports certified products and non-certified products to the top of corresponding blanking slot respectively according to the testing result.
