Abstract
The automatic sampling device of serum tube provided by the utility model, utilize the gear of step motor Direct driver small diameter, higher transmission positioning precision can be ensured, comparatively stable intermittent exercise is achieved by pinion wheel and the direct engaged transmission of gear wheel, thus drive the sample hose step motion be positioned on gear wheel, to meet the technical requirement that the actions such as follow-up application of sample, sampling have linked up.In optimal technical scheme, effectively can alleviate deadweight, lifting means operational efficiency by plate-like gear wheel is improved to ring-type; Below gear wheel, set up expansion sleeve is take into full account that its deadweight is comparatively large, can alleviate mechanical wear, lifting gear serviceable life by installing expansion sleeve additional.
Description
Technical field
The utility model relates to technical field of biomedical detection, is specifically related to the automatic sampling device of a kind of serum tube.
Background technology
Serum tube sampling device is the important component part of robotization immunity analysis instrument, its effect is transmitted with the mode of motion of continuous print, robotization sample to be detected, for the steps such as follow-up application of sample, sampling, detection are prepared, realize the robotization of entire flow simultaneously.Its automaticity of serum tube sampling device of prior art is lower, and its kinematic accuracy is limited simultaneously, and because the steps such as follow-up detection, analysis need higher positional precision, therefore its mechanical property of serum tube sampling device of prior art has much room for improvement.
Summary of the invention
The utility model is intended to the technological deficiency for prior art, provides a kind of serum tube automatic sampling device, to realize more accurate mechanical drive, the operational efficiency of lifting gear entirety simultaneously.
For realizing above technical purpose, the utility model by the following technical solutions:
The automatic sampling device of a kind of serum tube, it is characterized in that comprising base, step motor, pinion wheel, gear wheel, sample hose, wherein step motor, pinion wheel, gear wheel are placed on base, pinion wheel and gear wheel engaged transmission, pinion wheel is connected with step motor, and sample hose has several, is positioned at gear wheel marginal position.
Preferably, also comprise specimen holder, described specimen holder has several, is fixed on gear wheel marginal position, and several sample hoses described are placed in gear wheel marginal position by several specimen holders.
Preferably, also comprise expansion sleeve, described expansion sleeve is positioned at the junction of gear wheel and base.
Preferably, described step motor is placed in below base.
Preferably, described gear wheel in the form of a ring.
Preferably, described gear wheel is not more than 3:1 with the diameter ratio of pinion wheel.
The automatic sampling device of serum tube provided by the utility model, utilize the gear of step motor Direct driver small diameter, higher transmission positioning precision can be ensured, comparatively stable intermittent exercise is achieved by pinion wheel and the direct engaged transmission of gear wheel, thus drive the sample hose step motion be positioned on gear wheel, to meet the technical requirement that the actions such as follow-up application of sample, sampling have linked up.In optimal technical scheme, effectively can alleviate deadweight, lifting means operational efficiency by plate-like gear wheel is improved to ring-type; Below gear wheel, set up expansion sleeve is take into full account that its deadweight is comparatively large, can alleviate mechanical wear, lifting gear serviceable life by installing expansion sleeve additional.
