Problems solved by technology

This patent utilizes synchronous belt drive for linkage between three axes, but synchronous belt is easy to cause failure to a certain extent, and its service life is relatively short; and re-sampling after the first sampling may cause errors due to different sample properties ; If the industrial needles are replaced after each sampling, it will take a lot of time and labor, so there are still many deficiencies in the prior art, and the present invention will propose improvements to these problems

Abstract

The invention relates to the technical field of liquid collection, in particular to a sampling device for a liquid sample. The sampling device comprises a driving structure, a liquid suction head assembly and a cleaning structure, wherein the driving structure comprises an Z-axis driving mechanism, a Y-axis driving mechanism and an X-axis driving mechanism which are jointly matched; the sampling device is skillfully and accurately positioned by the driving mechanism, and can be cleaned and reutilized by the cleaning structure after the liquid suction head assembly completes primary sampling; when the liquid sample is collected for the second time, the influence by the previous collected liquid sample is avoided. The sampling device has the advantages that the structure arrangement is reasonable, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of liquid collection, in particular to a liquid sample sampling device. Background technique [0002] With the development of technology, more and more products and production are put into the experimental environment, and testing equipment is indispensable. When sampling, the representativeness, typicality, timeliness and procedurality of sample testing are usually considered, so there are certain requirements for sampling devices for liquid samples. [0003] For sample sampling and testing equipment, such as the patent application number "201520282469.9" discloses a large-capacity automatic water sampling instrument, its structure includes an instrument frame, an X-axis drive mechanism installed in the instrument frame, and a Y-axis drive mechanism , a Z-axis drive mechanism, a liquid suction head assembly and a peristaltic pump; the Z-axis drive mechanism is used to drive the liquid suction head assembly...
