Centrifugal mechanism and in vitro detection analyzer

Abstract

The invention relates to a centrifugal mechanism and an in vitro detection analyzer. The centrifugal mechanism comprises a centrifugal disc assembly, a circumferential positioning mechanism and a horizontal positioning mechanism, a positioning hole is formed in the centrifugal assembly in the vertical direction, the circumferential positioning mechanism comprises a circumferential detection sensor, the circumferential detection sensor is used for detecting the circumferential position of the centrifugal disc assembly, thus the centrifugal disc assembly is circumferentially positioned, the horizontal positioning mechanism comprise a positioning driving mechanism and a positioning piece which are connected in a transmission mode, the positioning driving mechanism can drive the positioning piece to move in the vertical direction, so that the positioning piece is inserted into the positioning hole, and thus the centrifugal disc assembly is horizontally positioned in a radial-centered mode.According to the centrifugal mechanism, a centrifugal cup can be accurately positioned.

Description

technical field [0001] The invention relates to the technical field of centrifugation, in particular to a centrifugal mechanism and an in vitro detection analyzer comprising the centrifugal mechanism. Background technique [0002] The centrifuge is the equipment that must be used in chemiluminescent in vitro diagnostic equipment. The centrifuge needs to rotate at a high speed to separate the serum and blood cells, which will inevitably generate large vibrations. In order to eliminate vibration, it is usually necessary to use springs for vibration damping. Due to the existence of the spring, the structure such as the centrifugal disc is on a floating mechanism. As the centrifuge works longer and longer, the spring may undergo permanent deformation and the centrifugal disc cannot maintain a horizontal state, which will make the centrifuge The centrifuge cups on the plate are difficult to position accurately. Once the position deviation of the centrifuge cup exceeds a certai...

AI Technical Summary

Problems solved by technology

Due to the existence of the spring, the structure such as the centrifugal disc is on a floating mechanism. As the centrifuge works longer and longer, the spring may undergo permanent deformation and the centrifugal disc cannot maintain a horizontal state, which will make the centrifuge Difficult to position the centrifuge cups on the plate accurately

Once the position deviation of the centrifuge cup exceeds a certain range, the mechanical arm used to automatically grab the centrifuge cup will not be able to accurately load and unload the centrifuge cup, which may lead to the failure of the entire working system and equipment downtime
