Description

Technical Field

[0001] The utility model relates to the technical field of biological detection, and more specifically to an automatic microbial culture detector. Background Art

[0002] Bacterial species counting is an important step in today's microbial testing. Bacterial species counting requires culturing the sample and observing the number of bacterial species after culturing to complete quality judgment.

[0003] Nowadays, in the process of culturing sample strains, a sample needs to be sampled multiple times, and the samples taken multiple times need to be cultured in groups (one group usually consists of 4-6 culture dishes). The traditional manual counting method is time-consuming and labor-intensive. At the same time, traditional culture instruments require the internal rack to be taken out, and then the culture dishes are placed on the rack and then moved back to the culture instrument for cultivation. This makes the use of such instruments more inconvenient, and therefore needs to be improved. Utility Model Content

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments, wherein the same components are denoted by the same reference numerals.

[0026] like Figure 1-5 As shown, a microbial automatic culture detector includes a main body 1, which is provided with a plurality of culture spaces 2 separated into upper and lower parts. A placement opening 3 is formed on the main body 1, and the placement opening 3 is used for allowing culture dishes to enter the culture space 2. A translation track 4 is provided in the culture space 2, and the translation track 4 is used to carry and horizontally transport the culture dishes. An outlet 5 is provided at the end of the translation track 4 on one side of the main body 1, and a shooting unit 6 is provided at the outlet 5. The shooting unit 6 is used to shoot the culture dishes. A moving passage 7 is provided between adjacent culture spaces 2, and a longitudinal moving device 8 is provided in the moving passage 7. The longitudinal moving device 8 is used to drive the culture dishes to move longitudinally.

[0027] When in use, the culture dish is placed into the culture space 2 along the placement port 3 and placed on the translation track 4, and is moved through the translation track 4 and transferred to other culture spaces 2 through the longitudinal moving device 8, thereby realizing the storage and culture of multiple culture dishes in the culture space 2.

[0028] After the cultivation is completed, the translation track 4 moves it to the end, and the status of the bacterial species in the culture dish is photographed through the shooting unit 6. The photographed bacterial species can be further identified by setting an identification module. The identification device is an existing technology and will not be described in detail here. The setting of the shooting unit 6 can image the culture dish after cultivation, which is convenient for subsequent processing to achieve automatic identification.

[0029] Preferably, the translation track 4 includes several track units 9 arranged parallel to each other, and the driving directions of adjacent track units 9 are opposite. The translation track 4 also includes an arc-shaped guide section 10, and the two ends of the guide section 10 are respectively connected to one end of the two track units 9 connected to each other.

[0030] When in use, the culture dish is moved by the track unit 9, and the culture dish is transferred to the guide section 10 on the track unit 9. The subsequent culture dishes are continuously transferred to drive the original culture dish through the guide section 10 and enter another section of the track unit 9 to realize the continued transfer of the culture dish.

[0031] The S-shaped track movement of the translation track 4 is achieved by the mutual cooperation between the track unit 9 and the guide segment 10 , thereby improving the space utilization of the culture space 2 .

[0032] Preferably, the track unit 9 includes a driving motor 11, a transmission belt 12 and a driven wheel 13, the driven wheel 13 is rotatably connected to the culture space 2, a driving wheel 14 is provided at the output end of the driving motor 11, and the transmission belt 12 is wound around the driving wheel 14 and the driven wheel 13 respectively, and a support frame 15 is provided in the culture space 2 corresponding to the transmission belt 12, and the support frame 15 is used to keep the transmission belt 12 supported.

[0033] The arrangement of the support frame 15 can prevent the conveyor belt 12 between the driving wheel 14 and the driven wheel 13 from collapsing, thereby ensuring the stability of the culture dishes on the conveyor belt 12 .

[0034] Preferably, the longitudinal moving device 8 includes a first cylinder slider 16 and a support plate 17. The first cylinder slider 16 is arranged corresponding to the moving passage 7. The support plate 17 is fixed to the first cylinder slider 16. A separation module 18 is provided on the support plate 17. The separation module 18 is used to drive the culture dish to separate from the support plate 17 and move toward the translation track 4.

[0035] Preferably, the separation module 18 includes a second cylinder slider 19 and a toggle rod 20 . The second cylinder slider 19 is disposed on the support plate 17 , and the toggle rod 20 is connected to the second cylinder slider 19 .

[0036] During use, after the culture dish is transferred to the support plate 17, the first cylinder slider 16 drives the support plate 17 to move longitudinally, thereby transferring the culture dish to the predetermined culture space 2, and further the second cylinder slider 19 drives the toggle rod 20 to move, thereby contacting the culture dish and driving the culture dish to leave the support plate 17 and transfer it to the conveyor belt 12 for subsequent transmission.

[0037] The arrangement of the first cylinder slider 16 and the second cylinder slider 19 makes the overall volume of the longitudinal moving device 8 smaller, thereby reducing the space requirement and making the overall structure more compact.

[0038] Preferably, a temperature control unit and a humidity control unit are provided on the upper end surface of the culture space 2, which are used to control the temperature and humidity in the culture space 2 respectively. The temperature control unit and the humidity unit are prior art and will not be described in detail here.

[0039] Preferably, a receiving plate 21 is provided at a position of the main body 1 corresponding to the outlet 5 , and one end of the receiving plate 21 is hinged to the outlet 5 so that the receiving plate 21 can be rotated to open or close the outlet 5 .

[0040] In the initial state, the receiving plate 21 covers and closes the outlet 5, so that the culture space 2 is in a closed state, thereby improving the stability of the temperature and humidity in the culture space 2. When in use, the outlet 5 is opened by pulling the receiving plate 21, and then the culture dish is transferred to the receiving plate 21 through the translation track 4 to complete the sample removal.

[0041] Preferably, an operation panel 22 is provided on one side of the main body 1, through which the longitudinal moving device 8 and the translation track 4 can be controlled, and the temperature control unit and the humidity control unit can also be controlled to meet experimental needs.

[0042] At the same time, the culture time can be preset through the operation panel, and after the preset time is reached, the culture dishes are automatically transported by the translation track 4 and the longitudinal movement device 8 to achieve automatic shooting of multiple groups of culture dishes.

[0043] Preferably, a cover 23 is hingedly provided on the main body 1 , and the cover 23 is used to open the placement opening 3 .

[0044] The cover 23 can maintain the culture space 2 in a sealed state during the culture process, thereby cooperating with the receiving plate 21 to improve the stability of the culture environment in the culture space 2 .

[0045] Preferably, the conveyor belt 12 is provided with limit blocks 24 , and an accommodating space 25 for accommodating a culture dish is formed between adjacent limit blocks 24 .

[0046] The setting of the limiting blocks 24 can divide the culture dishes, thereby facilitating the photographing unit 6 to photograph a single culture dish, thereby avoiding photographing interference caused by multiple culture dishes being attached too close to each other.
