Automatic bacterial colony selecting instrument and selecting method

Abstract

The present application discloses an automatic bacterial colony selecting instrument and a selecting method. The automatic bacterial colony selecting instrument comprises a workbench; the workbench is rotationally connected with a rotating disc arranged in a disc shape and a power piece used for driving the rotating disc to rotate in the circumferential direction of the rotating disc; a plurality of teasing needles are evenly distributed on the rotating disc in the circumferential direction of the rotating disc at intervals; a picking station, an inoculating station and a cleaning station are sequentially arranged on the workbench in the moving direction of the rotating disc; the cleaning station comprises a cleaning mechanism used for cleaning the teasing needles, a heating mechanism used for heating the teasing needles and a cooling mechanism used for cooling the teasing needles; a picking station driving part and an inoculating station driving part which correspond to the picking station and the inoculating station respectively are arranged on the workbench; and automatic teasing needle resetting mechanisms which correspond to the teasing needles one to one are further fixedly arranged on the rotating disc. The automatic bacterial colony selecting instrument has an effect that a teasing needle cleaning path of the cleaning station is prolonged to the maximum extent, and then the teasing needle cleaning time is prolonged to the maximum extent.

Description

technical field [0001] The invention relates to the field of colony selection equipment, in particular to an automatic colony selection instrument and a selection method. Background technique [0002] In the fields of large-scale gene sequencing, biochips, biopharmaceuticals, immunoassays, and chemical synthesis, there are many processes that urgently need robots to replace tedious manual work to ensure high-throughput, high-precision assembly line production needs. In the gene sequencing workflow, the workload of clone picking is very heavy, that is, the host cells containing the foreign gene insertion are picked into the liquid medium. During this process, an automatic colony picker is usually used for colony picking. Pick a shift operation. [0003] In the related art, the automatic colony sorting instrument usually includes a workbench, a transmission part arranged on the workbench and a power part for driving the transmission part to move along its own circumference. ...

AI Technical Summary

Problems solved by technology

[0005] In view of the related technologies mentioned above, the inventor believes that there are the following defects: the picking needles are reused during the working process of the automatic colony picker, and it needs to be cleaned and disinfected after each picking is completed, while the automatic colony picker in the related art The needle cleaning process of the instrument is controlled by jog, which leads to limited cleaning time of the needle, and there are factors of incomplete cleaning, which reduces the reliability and scientificity of the experimental results. Therefore, there is a certain room for improvement.
