Full-automatic sample injector transmission device

Abstract

The invention discloses a full-automatic sample injector transmission device, and belongs to the technical field of detection devices. The device comprises a sample injection frame, a sample injection arm and a Z-axis transmission mechanism. The sample injection arm comprises a fixed part and a moving part. The moving part is vertically connected with the fixed part in a sliding manner. The Z-axis transmission mechanism comprises a Z-axis transmission wheel, a Z-axis transmission shaft and a Z-axis driving part. The Z-axis transmission wheel is rotationally connected with the sample injection arm. The Z-axis transmission shaft is rotationally connected with the sample injection frame. According to the Z-axis transmission mechanism, the Z-axis transmission wheel drives the moving part to vertically slide relative to the fixed part, and the Z-axis transmission wheel can slide along the Z-axis transmission shaft. The full-automatic sample injector transmission device is reasonable in structure and small in occupied size, the integration degree of the full-automatic sample injector is improved, simultaneous sampling and sample injecting by multiple sample injection arms are achieved, and the sampling and sample injecting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of detection devices, in particular to a transmission device for a fully automatic sampler. Background technique [0002] Sampling equipment is used for fully automated sample and reagent dilution, distribution, mixing, and automatic management of related data documents. Multiple sampling channels refer to having multiple samplers. The multi-channel sampling equipment can be used for all automatic liquid sampling work in the process of medical inspection, food inspection, biological experiment, etc., which can improve the efficiency of sampling and adding. [0003] The transmission device of the existing sampling equipment occupies a large volume, and the transmission structure is unreasonable. Limited by the transmission structure, the existing automatic sample injection device has a low degree of automation and integration, and can only achieve a small number of sample injection arms at the same time.

Problems solved by technology

[0003] The transmission device of the existing sampling equipment occupies a large volume, and the transmission structure is unreasonable. Limited by the transmission structure, the existing automatic sample injection device has a low degree of automation and integration, and can only achieve a small number of sample injection arms at the same time. Loading

Especially the transmission structure in the Z-axis direction needs to move synchronously with the sample loading arm, and its excessive volume is the key point and difficulty that hinders the automatic sample loading device from realizing synchronous sampling and loading with multiple sample loading arms.
