Sample frame conveying device

Abstract

The invention discloses a sample frame conveying device which comprises a sample frame loading part used for storing vertically stacked sample frames, wherein a conveying opening is formed in the bottom of the sample frame loading part; a loading area switch part which is arranged around the conveying opening and is used for controlling the sample frame to enter / exit from the conveying opening; and a linkage conveying part which is provided with a first supporting plate moving in the Z direction and a second supporting plate moving in the Y direction, wherein the first supporting plate is arranged corresponding to the conveying opening, and the second supporting plate and the grabbing position are arranged at the same height. The sample frame conveying device is ingenious in structure, small in size and capable of accurately bearing a sample frame and stably conveying the sample frame, and the requirements for sample feeding and sample frame recycling are met; meanwhile, whole-support or single-support sample injection can be realized, samples can be added at any time in the experiment process, and the sample injection efficiency and the sample injection flexibility are improved.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnostic equipment, in particular to a sample rack transmission device. Background technique [0002] In order to meet the requirements of automatic analysis, the sample rack transfer device is widely used in biochemical analyzers, immunological analyzers and laboratory assembly line analysis systems. The sample rack transmission device is provided with an independent sample rack loading area and a sample rack recovery area, a loading channel is provided between the sample rack loading area and the testing equipment, and a recovery channel is provided between the sample rack recycling area and the testing equipment. When working, untreated samples are placed on the sample rack, and are sent from the sample rack loading area to the testing equipment through the loading channel. After the testing items are completed, they are sent back to the sample rack recovery area through the recovery channel...

AI Technical Summary

Problems solved by technology

Most of the existing sample rack transport devices adopt the structure of transporting the sample racks in the same plane, which cannot satisfy the situation that there is a height difference between the loading and unloading position and the grabbing position of the sample rack; secondly, there is a defect that samples cannot be added at any time , limited injection efficiency and flexibility
