Description

Technical Field

[0001] The utility model relates to the technical field of colony counters, in particular to a colony counter photographing and scanning device. Background Art

[0002] Culturing microorganisms on nutrient-rich agar media at a defined temperature and humidity, and then counting the number of colonies after cultivation, is a quality control method widely used in microbial limit testing in the food and pharmaceutical industries. Furthermore, the dynamics of microbial growth is increasingly being used in strain analysis and personalized antimicrobial therapy.

[0003] At present, the culture and counting method commonly used in the industry is still manual counting after culture in an ordinary constant temperature incubator. Counting may occur after the end of culture or multiple times during the culture process. However, during the operation, since the inspectors cannot obtain dynamic growth change information during the microbial culture process, there is an error between the manually delayed colony count and the true value, which in turn affects the accuracy of the counting results, especially for the counting of adherent colonies, and the operation process consumes a lot of manpower. To solve the above problems, the patent document with application number 202220769905.5 mentions a fully automatic colony culture counting system that can automatically scan and take pictures of culture dishes.

[0004] However, the system mentioned in the above patent still has certain problems during use: when performing the code scanning and photo taking processes on this system, the culture dishes must be placed on two different platforms respectively, which will cause the entire counting process time to be longer; at the same time, the position in the culture room is fixed, and the code scanning and recognition platform and the photo taking and counting platform are placed separately, which will inevitably occupy one more position, and then the culture dish rack will have one less workstation, affecting the volume of the entire culture room.

By arranging the photographing unit within the storage unit, the culture dishes can be rotated synchronously while photographing them to scan barcodes on the circumferential surfaces of the culture dishes, thereby avoiding the problem in the prior art of requiring the culture dishes to be placed on two separate platforms during the scanning and photographing steps, which results in a longer counting process. At the same time, the two workstations are combined into a single workstation, reducing the occupancy of the culture dish rack station and increasing the capacity of the culture chamber for culture dishes.

[0011] Preferably, the shooting unit is a high-definition camera, which is arranged inside the rotating frame and fixedly connected to the rotating frame.

[0012] Preferably, the rotating unit includes a motor bracket, a rotating motor and a rotating part, the upper end of the motor bracket is fixedly connected to the first flange, the lower end of the motor bracket is fixedly connected to the rotating motor, the output shaft of the rotating motor is connected to the rotating part, the upper part of the rotating part is a accommodating cavity of an inner cavity structure, the high-definition camera is located inside the accommodating cavity, the lower part of the rotating part is a rotating shaft, and the rotating shaft is connected to the output shaft of the rotating motor through a coupling.

[0017] It can be seen from the above technical solution that the advantages of the present invention are: by arranging the shooting unit inside the storage unit, the culture dish can be rotated synchronously when taking a picture of the culture dish to scan the barcode on the circumferential surface of the culture dish, thereby avoiding the problem in the prior art that the culture dish must be placed on two different platforms during the scanning and photographing processes, which causes the entire counting process time to become longer.
