The invention relates to the field of semiconductor production, in particular to a base plate lifting mechanism. The base plate lifting mechanism comprises a bearing table, a pin, a pin mounting ring,a lifting base, a lifting drive device and a lifting transmission assembly, wherein the lifting base is driven by the lifting drive base to ascend and descend; the lifting drive device is used for transmitting force moment through the lifting transmission assembly; the upper end of the lifting base is fixedly connected to the pin mounting ring; the bearing table is arranged above the pin mountingring; the pin is arranged on the pin mounting ring in the peripheral direction; a through hole for allowing the pin to pass through is formed in the bearing table in the peripheral direction; the bearing table is equipped with a fixed pin and a movable clamping pin; and the base plate is fixed by the fixed pin and the clamping pin. The base plate lifting mechanism can effectively prevent a base plate from being damaged, and can precisely transfer the base plate.
