Intelligent centrifuge control method and device in full-automatic cell cultivation system

Abstract

The invention relates to an intelligent centrifuge control method and a device in a full-automatic cell cultivation system. A controller controls a relay in a centrifuge; a servo motor drives a push rod to pull a cover plate; the cover plate moves to the left side so as to open the cover plate of the centrifuge; a mechanical gripper grabs a centrifugal pipe; the grabbed centrifugal pipe is put in an initial object carrying frame corresponding to an initial point; a sensor sends a detecting signal to detect if the object carrying frame in the initial point position loads the centrifugal pipe; if the centrifugal pipe is put in, a rotating frame rotates by an angle until all centrifugal pipes are put on the rotating frame; when all the centrifugal pipes are placed, the angle rotation is finished, the push rod pushes the cover plate, the cover plate of the centrifuge is closed, and the rotating frame slowly accelerates to rotate for centrifugal work; labors are reduced to participate in a cell cultivation environment in the whole process; and the working efficiency of the centrifuge for centrifugating cells can be improved.

Description

technical field [0001] The invention relates to the technical field of cell culture, in particular to an intelligent centrifuge control method and device in a fully automatic cell culture system. Background technique [0002] In the field of cell biology research and life science research, cell culture is the most basic link. Cell culture is a culture process in which cells are propagated and proliferated using nutrients, etc., in an artificial environment, and used for "various purposes". [0003] In the process of cell culture, the centrifugal separation device is an effective method to realize the solid-liquid separation of cell culture. The cell solution is added to the centrifuge tube, and the centrifuge tube is transferred to the centrifuge. After several minutes, the cells are in the centrifuge. Under the traction, they will gather at the bottom of the centrifuge tube. After the centrifuge finishes running, just discard the supernatant in the centrifuge tube. At this...

AI Technical Summary

Problems solved by technology

In the fully automatic cell culture system in the prior art, when the cell culture is separated, an electric button is usually added to the casing of the centrifuge, and the upper cover of the centrifuge is opened or closed by pressing the electric button, and then the centrifuge is separated one by one by the staff. Put the centrifuge tube into the centrifuge. During the rotation of the centrifuge, the turntable rotates according to the set speed. This method has the following disadvantages: 1. It requires manpower to press the button to open or close the upper cover; 2. , In the fully automatic cell culture system, the staff needs to wait for the configuration of the culture solution by the device, and then put the centrifuge tubes containing the culture solution into the centrifuge one by one, and then press the electric button to close the centrifuge. Cover, artificially placed centrifuge tubes with culture medium will easily interfere with unnecessary impurities to contaminate the culture medium, and cannot guarantee the culture environment of cells; 3. If the staff does not press the electric button in time, it will easily lead to the failure of the entire culture system The work collapses and the work efficiency is extremely low; 4. During the rotation of the turntable according to the speed, when it needs to stop, the turntable will continue to move until it stops due to inertia
