Description

Technical Field

[0001] The invention relates to the technical field of microbial detection, in particular to a fully automatic intelligent detection device for total coliform bacteria in a laboratory. Background Art

[0002] The water contains a large number of pathogenic microorganisms that can seriously endanger the health of residents. Drinking water problems caused by unqualified microorganisms are the most common. Therefore, it is necessary to do a good job in microbial testing to ensure healthy water quality and reduce the risk of drinking water-related diseases.

[0003] Natural water contains a variety of microorganisms, most of which are beneficial to the human body, and only a small part can cause disease. There are many types of pathogenic microorganisms in water, but their number is small and they are more likely to mutate and die. At present, there is still a lack of effective quantitative separation methods for these pathogens. Usually, indicator microorganisms that are easy to detect in water are used instead of pathogenic microorganisms to estimate the pollution status.

[0004] At present, the detection indicators used for the sanitation evaluation of drinking water, source water and surface water are total coliform group and Escherichia coli. The sanitary conditions of the water source are evaluated by detecting the indicator bacteria of the above two indicators. Total coliform group refers to a group of Gram-negative non-spore-forming bacilli that can ferment lactose, produce acid and gas, and are aerobic and facultative anaerobic when cultured at 37°C for 24 hours. The membrane filtration method and the multi-tube fermentation method in the standard detection method have a relatively long reaction time during the detection process, usually requiring 1 to 3 days to obtain the test results, and the operation process is relatively complicated, which cannot meet the needs of rapid detection of water source hygiene.

[0005] Compared with the membrane filter method, paper disc method and multi-tube fermentation method, the enzyme substrate method has the advantages of simple operation, low false positive, accurate results, no special requirements for experimental sites and personnel, no need for confirmation experiments, and short detection time. The existing methods for detecting total coliform bacteria in water lack dedicated culture equipment, usually manually prepare culture media, require a large number of glassware to be sterilized, are time-consuming and labor-intensive, and have low detection efficiency.

[0050] Combination Figures 1 to 7 According to an embodiment of the present invention, a laboratory total coliform group fully automatic intelligent detection device is provided, including: a base plate 1, and a sample dosing and mixing module K and a sample transfer module P installed on the base plate 1.

[0051] In order to explain the present invention more clearly, an XYZ space rectangular coordinate system is established in this embodiment.

[0052] like Figure 1 As shown, the sample-dosing and mixing module K and the sample-transferring module P are installed on a bottom plate, and the sample-dosing and mixing module K is located on one side of the sample-transferring module P.

[0053] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 According to an embodiment of the present invention, the sample dosing and mixing module K comprises: a first three-axis mechanical arm 2, and the first three-axis mechanical arm 2 is equipped with a cover opening jaw 201 and a powder box jaw 202. The first three-axis mechanical arm 2 is configured to drive the cover opening jaw 201 and the powder box jaw 202 to move along the three-axis directions of the X axis, the Y axis and the Z axis.

[0054] A fixed clamping claw 7, a shaking plate 8, a medicine powder box push rod 10, and a powder opening slot 9 are installed on one side of the first three-axis mechanical arm 2.

[0055] The first three-axis mechanical arm 2 is used to drive the opening jaw 201 holding the sample bottle 11 to transfer to the fixed jaw 7. The fixed jaw 7 is used to fix the sample bottle 11, and the opening jaw 201 is used to open the cover of the sample bottle 11.

[0056] Furthermore, the fully automatic intelligent detection device also includes a sample bottle tray 3. The sample bottle tray 3 is placed on the bottom plate 1 and is used to store multiple sample bottles 11, and the sample bottles 11 contain water samples to be detected. In this embodiment, the sample bottle tray 3 has a socket for placing the sample bottles 11. Furthermore, the socket arrangement of the sample bottle tray 3 is 5×5, and 25 sample bottles 11 can be placed, and the specification of the sample bottles is 100ml.

[0057] The first three-axis robot arm 2 drives the uncapping jaw 201 to move above the sample bottle tray 3 , and the uncapping jaw 201 clamps a sample bottle 11 . The first three-axis robot arm 2 drives the uncapping jaw 201 clamping the sample bottle 11 to transfer to the fixed jaw 7 , and the fixed jaw 7 fixes the sample bottle 11 .

[0058] Furthermore, a stage 6 is arranged below the fixed clamp 7.

[0061] Furthermore, the fully automatic intelligent detection device also includes a powder storage tray 4. The powder storage tray 4 is placed on the bottom plate 1 and is used to store a plurality of powder boxes 5, wherein the powder boxes 5 contain powder. In this embodiment, the powder storage tray 4 stores the powder boxes 5 in rows, with a total of 5 rows of powder boxes 5, and each row includes 5 powder boxes 5.

[0062] The first three-axis robotic arm 2 drives the powder box clamp 202 to move above the powder storage tray 4, and the powder box clamp 202 clamps a row of powder boxes 5. The first three-axis robotic arm 2 drives the powder box clamp 202 clamping the powder boxes 5 to transfer to the powder opening slot 9, and places the row of powder boxes 5 in the powder opening slot 9.

[0063] The medicine powder box push rod 10 is arranged at one side of the powder opening slot 9, and the width of the medicine powder box push rod 10 is the same as the width of the medicine powder box 5. After a row of medicine powder boxes 5 are placed in the powder opening slot 9, the medicine powder box push rod 10 moves toward the medicine powder box 5 to generate an impact force on one medicine powder box 5, flushing off the top of the medicine powder box 5, thereby unsealing the medicine powder box 5.

[0064] When one medicine powder box 5 is unsealed, the medicine powder box clamping claw 202 drives the medicine powder box 5 to move a distance of one medicine powder box 5 along the X-axis direction, and the medicine powder box push rod 10 performs an unsealing operation on the next medicine powder box 5 .

[0065] According to the embodiment of the present invention, the first three-axis robot arm 2 is also used to drive the powder box clamping jaw 202 holding the unsealed powder box 5 to move above the unsealed sample bottle 11.

[0066] After the medicine powder box 5 is unsealed, the first three-axis robot arm 2 drives the medicine powder box clamping jaws 202 holding the unsealed medicine powder box 5 to move to the top of the uncapped sample bottle 11 (above the fixed clamping jaws 7).

[0067] The powder box clamp 202 of the present invention is configured to rotate around the X-axis. After the powder box clamp 202 holding the unsealed powder box 5 is transferred to the top of the unsealed sample bottle 11, the powder box clamp 202 rotates around the X-axis to pour the powder in the powder box 5 into the sample bottle 11.

[0069] The second three-axis mechanical arm 13 is provided with a quantitative disk clamp 1301. The second three-axis mechanical arm 13 is configured to drive the quantitative disk clamp 1301 to move along three axes: the X axis, the Y axis and the Z axis.

[0070] The second three-axis robot arm 13 is used to drive the quantitative disk clamping claw 1301 holding the quantitative disk 20 to move to the quantitative disk opening mechanism 21.

[0071] Furthermore, the fully automatic intelligent detection device also includes a quantitative tray storage basket 18. The quantitative tray storage basket 18 is placed on the bottom plate 1 and is used to store multiple quantitative trays 20. In this embodiment, the quantitative tray 20 adopts a 97-hole quantitative tray, such as Figure 5 shown.

[0072] The second three-axis robot arm 13 drives the quantitative plate clamp 1301 to move to above the quantitative plate storage basket 18, and the quantitative plate clamp 1301 clamps a quantitative plate 20. The second three-axis robot arm 13 drives the quantitative plate clamp 1301 clamping the quantitative plate 20 to transfer to the quantitative plate opening mechanism 21, and places the quantitative plate 20 in the quantitative plate opening mechanism 21.

[0073] Combination Figure 6 and Figure 7 The quantitative disk opening mechanism 21 of the present invention comprises: a quantitative disk support 2101, a pressure head 2102 and a suction nozzle 2103. The quantitative disk support 2101 is installed on the bottom plate 1, the pressure head 2102 is installed above the quantitative disk support 2101, and the suction nozzle 2103 is installed on one side of the pressure head 2102. The quantitative disk support 2101 has a slot opened along the Z-axis direction.

[0074] After the second three-axis robot arm 13 drives the quantitative tray clamping claw 1301 holding the quantitative tray 20 to transfer to the quantitative tray opening mechanism 21 , the quantitative tray clamping claw 1301 places the quantitative tray 20 in the slot of the quantitative tray support 2101 .

[0075] The quantitative disk opening mechanism 21 is used to open the quantitative disk 20. Specifically, Figure 7 As shown, when the second three-axis mechanical arm 13 drives the quantitative disk clamping claw 1301 holding the quantitative disk 20 to transfer to the quantitative disk opening mechanism 21, the quantitative disk clamping claw 1301 places the quantitative disk 20 in the slot of the quantitative disk support 2101; the pressure head 2102 squeezes the side of the quantitative disk 20, and the suction nozzle 2102 absorbs the sealing film 2001 of the quantitative disk 20, so that the sealing film 2001 located on the top of the quantitative disk 20 is separated from the quantitative disk 20, and an opening is formed on the top of the quantitative disk 20, as shown in FIG. Figure 7 shown.

[0076] like Figure 2 As shown, according to an embodiment of the present invention, the transfer clamp 12 is used to transfer the sample bottle 11 added with the medicine powder to the shaking plate 8. The shaking plate 8 is used to mix the water sample and the medicine powder in the sample bottle 11.

[0077] The transfer jaw 12 is also used to transfer the sample bottle 11 after the water sample and the medicine powder are mixed to the quantitative disk opening mechanism 21, and add the mixed liquid after the water sample and the medicine powder in the sample bottle 11 to the opened quantitative disk 20.

[0078] The transfer jaw 12 is configured to reciprocate along the Y-axis direction and reciprocate along the Z-axis direction. Figure 2 and Figure 6The sample transfer module P further includes: a guide rail 22 mounted on the bottom plate 1, and a slider 23 slidably matched with the guide rail 22. The transfer jaw 12 is connected to the slider 23. Specifically, the transfer jaw 12 is connected to the slider 23 via a slide rail slider (not shown in the figure), so that the transfer jaw 12 reciprocates along the Z-axis direction.

[0079] The slider 23 drives the transfer jaw 12 to reciprocate along the guide rail 22 (in this embodiment, the direction in which the guide rail 22 extends is parallel to the Y-axis direction, and the transfer jaw 12 reciprocates along the Y-axis direction), transferring the sample bottle 11 with the powder added to the shaking plate 8, and transferring the sample bottle 11 after the water sample and the powder are mixed to the quantitative plate opening mechanism 21.

[0080] Specifically, Figure 2 As shown, the slider 23 drives the transfer jaw 12 to move along the guide rail 22 to the position of the sample bottle 11 (above the fixed jaw 7) with the powder added, and the fixed jaw 7 releases the sample bottle 11. The transfer jaw 12 clamps the sample bottle 11 and transfers the sample bottle 11 with the powder added to the shaking plate 8.

[0081] The shaking plate 8 of the present invention is configured to rotate around the Z-axis direction. For example, a stepper motor is arranged at the bottom of the shaking plate 8 to drive the shaking plate 8 to rotate around the Z-axis direction.

[0082] Furthermore, the shaking plate 8 is cylindrical, and the height of the shaking plate 8 is two-thirds of the height of the sample bottle 11, and is adapted to the height of the sample bottle 11 so that the water sample and the medicine powder are fully mixed.

[0083] After the sample bottle 11 containing the medicine powder is transferred to the shaking plate 8 , the shaking plate 8 rotates around the Z-axis direction to mix the water sample and the medicine powder in the sample bottle 11 .

[0084] After the water sample and the medicine powder in the sample bottle 11 are mixed, the transfer jaw 12 clamps the sample bottle 11 , and the slider 23 drives the transfer jaw 12 to move along the guide rail 22 to above the quantitative disk opening mechanism 21 .

[0085] The transfer jaw 12 of the present invention is configured to rotate around the X-axis direction. After the transfer jaw 12 transfers the sample bottle 11 after the water sample and the medicine powder are mixed to the top of the quantitative disk opening mechanism 21, the transfer jaw 12 rotates around the X-axis direction to add the mixed liquid after the water sample and the medicine powder in the sample bottle 11 are mixed into the quantitative disk 20 after the opening.

[0087] The second three-axis mechanical arm 13 is also used to drive the quantitative plate clamping claw 1301 holding the quantitative plate 20 added with the mixed liquid to be transferred to the top of the rolling conveyor belt 16. The quantitative plate clamping claw 1301 is used to place the quantitative plate 20 added with the mixed liquid on the rolling conveyor belt 16.

[0088] Specifically, after the transfer clamp 12 adds the mixed liquid obtained by mixing the water sample and the medicine powder in the sample bottle 11 into the opened quantitative plate 20, the second three-axis robotic arm 13 drives the quantitative plate clamp 1301 to move above the quantitative plate opening mechanism 21, and the quantitative plate clamp 1301 clamps the quantitative plate 20 with the mixed liquid added.

[0091] Further, a pressing plate 15 is installed on one side of the rolling conveyor belt 16. When the quantitative plate clamp 1301 places the quantitative plate 20 with the mixed liquid added on the rolling conveyor belt 16, the pressing plate 15 presses down to fit the quantitative plate 20 with the mixed liquid added to the mold on the rolling conveyor belt 16.

[0092] The rolling conveyor belt 16 is used to deliver the quantitative disk 20 with the mixed liquid added to the sealing machine 17. The sealing machine 17 is used to seal the opening of the quantitative disk 20 with the mixed liquid added.

[0093] After the quantitative disk clamp 1301 places the quantitative disk 20 with the mixed liquid added on the rolling conveyor 16, the rolling conveyor 16 tilts the quantitative disk 20 with the mixed liquid added downward into the sealing machine 17, and the sealing machine 17 seals the opening of the quantitative disk 20 with the mixed liquid added.

[0094] like Figure 4 As shown, the third three-axis robot arm 14 is equipped with a suction cup 24. The third three-axis robot arm 14 is configured to drive the suction cup 24 to move along the three axes of the X axis, the Y axis and the Z axis.

[0095] The third three-axis robot arm 14 is used to drive the suction cup 24 to absorb the sealed quantitative disk 20 and transfer the sealed quantitative disk 20.

[0096] Furthermore, the fully automatic intelligent detection equipment also includes a quantitative tray temporary storage basket 19. After the sealing machine 17 seals the quantitative tray 20 added with the mixed liquid, the rolling conveyor belt 16 sends the sealed quantitative tray 20 out of the sealing machine 17. The third three-axis mechanical arm 14 drives the suction cup 24 to absorb the sealed quantitative tray 20 and transfer the sealed quantitative tray 20 to the quantitative tray temporary storage basket 19.
