Description

TECHNICAL FIELD

[0003] According to Chinese patent CN216705129U, a chip high-low temperature sorting test machine is disclosed. The machine reabsorbs the chip through a carrying manipulator, places the chip in a workpiece placement position in a transfer disc, and a transplanting manipulator takes the chip from the transfer disc and places it in a preheating position in a preheating disc. After the preheating disc preheats the chip to a specified temperature, the transplanting manipulator takes the chip from the preheating disc and places it in a detection station. A chip pressure test module slides to the detection station directly above, presses a temperature control head on the surface of the chip through a positioning pin hole to control the temperature, and controls the temperature of the chip in real time through the temperature control head during the test process. The transplanting manipulator takes back the test chip and places it back in the transfer disc to send the chip out of the sealed shuttle channel, and the carrying manipulator takes away the chip. However, the number of chips accommodated by the detection station is limited, and after each detection is completed, the transplanting manipulator needs to remove the chip and take the chip from the preheating disc and place it in the detection station, which greatly reduces the detection efficiency.
