Pre-uncovering device and chemiluminescence immune analyzer

The invention relates to a pre-uncovering device and a chemiluminescence immune analyzer. The pre-uncovering device is used for performing pre-uncovering of containers with anti-evaporation covers. The pre-uncovering device comprises an opening part and a driving part, wherein the opening part is provided with through holes vertically arranged in an extending mode, the through holes are used for letting sampling probes pass through, so that the sampling probes can enter the containers for sampling after the opening part opens the anti-evaporation covers; and the driving part is connected withthe opening part, and the driving part can drive the opening part to move along the containers in the axial directions for opening the anti-evaporation covers. The pre-uncovering device can perform the pre-uncovering of the containers with the anti-evaporation covers, erroneous judgment of a liquid level detector is avoided from appearing in the process of the sampling probes passing through the anti-evaporation covers, a
