The working principle and the process of the full-automatic inoculation instrument are as follows:

(1) stock preparation

The sample cup rotary feeder 7 is provided with sample cups 12 of the same or different samples, and the culture dish 10 is filled in the culture dish stock feeder 2.

(2) Feeding of materials

The machine works, the culture dish 10 is firstly fed into the first conveyer belt 210 by the stock feeding unit 220, the first conveyer belt 210 feeds the culture dish 10 to the second conveyer belt 320 on the culture dish transferring device 3, and then the culture dish 10 is fed to the third conveyer belt 410 by the second conveyer belt 320 and the first lifting linear module 310.

(3) Inoculation streaking

The culture dish 10 arrives at the working position of the first culture dish cover taking and rotating device 4 through the third conveyer belt 410, the culture dish 10 is clamped by the culture dish rotating mechanism 420, and then the cover body 11 of the culture dish 10 is taken down by the culture dish cover taking mechanism 430;

the sample cup rotating and feeding device 7 rotates, and the code scanner 706 scans codes to obtain the information of each sample cup 12; the first scribing device 5 grabs the inoculation rod 13 in the corresponding sample cup 12, falls in the culture dish 10, drives the culture dish 10 to rotate by the culture dish rotating mechanism 420, and then is matched with the three-axis platform 510 to inoculate in the culture dish 10 and draw a corresponding line;

after completion of the inoculation score, the inoculation rod 13 is withdrawn and the cap 11 is closed.

Install culture dish stock feedway 2, culture dish transfer device 3, culture dish on the inoculation platform 1 and get lid rotary device 4, first marking device 5, second marking device 6, rotatory feedway 7 of sample cup and culture dish and pile up output device 8.

(4) Zoning marking-out

The culture dish 10 comes to the working position of the second culture dish cover taking and rotating device 4 through the third conveyer belt 410, and is clamped firstly and then taken;

the streaking bar 630 of the second streaking device 6 is turned towards the inoculating head feed mechanism 610, inserted into the inoculating head 14 in the feed tube 614, withdrawn, turned towards the culture dish 10, and dropped into the culture dish 10; then the culture dish 10 is driven to rotate, and a corresponding line is drawn in the culture dish 10 by matching with the two-axis platform 620, so that the partition line drawing is completed; when the next culture dish 10 comes in, the scribing rod 630 can be rotated to replace one surface of the inoculating head 14 for scribing until the inoculating head 14 finishes using three surfaces; then the inoculating head 14 is turned to the inoculating head feeding mechanism 610 and falls into the blocking groove 617, the inoculating head 14 is pulled out, and the waste inoculating head 14 falls into the waste material falling opening 613;

after the zone-dividing line is scribed, the inoculating head 14 is withdrawn and the cap 11 is closed.

(5) Discharging

The third conveyer belt 410 sends the culture dish 10 to the supporting plate 823 in the lifting pushing mechanism 820, and the push plate 825 pushes the culture dish 10 to the fourth conveyer belt 810; when stacking is required, the culture dishes 10 are lifted by the third lifting linear module 821 to be stacked. The seventh sensor 827 may determine how high the stack is.

The utility model provides a full-automatic inoculation appearance collects streak inoculation sample function, subregion streak function, changes inoculation head function, assembly line processing culture dish function in an organic whole, and functional diversity and degree of automation are high, and further reduction personnel participate in, improve experimenter's security and experimental result's accuracy.

The above description is only an example of the present invention, and certainly, the scope of the present invention should not be limited thereto, and therefore, the present invention is not limited to the above description.
