This invention relates to the field of semiconductor product testing technology and discloses a high and low temperature testing and conveying device for semiconductor products. The device includes a carrier on which a tray is placed. Several sets of lower pressure plates and upper pressure components are respectively installed on the carrier. The lower pressure plates and upper pressure components are drively connected and move in opposite directions. One set of lower pressure plates has a positive trapezoidal plate, and an inverted trapezoidal plate is also provided inside the testing chamber. The inverted trapezoidal plate cooperates with the positive trapezoidal plate to move the lower pressure plates downwards. By setting relatively movable lower pressure plates and pressure cylinders, the cooperation of the inverted and positive trapezoidal plates during carrier movement drives the automatic clamping of the tray. This forcibly corrects the unevenness of the tray top caused by long-term wear, ensuring that the tray top always remains level. This guarantees that the suction cup can accurately pick up semiconductor products from all positions within a fixed stroke, effectively avoiding missed tests due to partial tray sagging, and significantly improving the integrity and reliability of the test.
