Abstract
Description
Technical Field
[0001] This application relates to the field of microbial treatment device technology, and more specifically, to an intelligent pathogen coating device. Background Technology
[0002] Pathogen plating is a fundamental procedure in microbiological experiments and medical testing. Specifically, it involves inoculating a sample containing pathogens or other microorganisms onto the surface of a solid culture medium in a petri dish. This allows the microorganisms in the sample to grow and multiply on the medium, forming observable colonies, thereby achieving the purpose of isolation, culture, identification, or counting of pathogens. Common plating methods include using tools such as inoculation loops, plating sticks, or swabs to streak or smear the sample onto the culture medium surface, often relying on manual labor or semi-automated equipment.
[0003] In existing pathogen coating devices, the storage, transfer, and processing areas for culture dishes are dispersed, often requiring multi-directional transfer of dishes. This involves complex and time-consuming paths, and interference between components is prone to occur, resulting in excessively long waiting intervals and low overall processing efficiency. The dispersed layout also leads to a complex overall equipment structure, a large footprint, and low space utilization. Furthermore, the loading, transfer, and storage of culture dishes often require manual assistance, resulting in insufficient automation. This not only increases labor costs but also poses a risk of contamination due to human error. Utility Model Content

[0023] The present application provides an intelligent pathogen coating device.
[0024] Please see Figures 1 to 4 The intelligent bacterial coating device includes a base 1, on which a petri dish rack 2, a petri dish conveying mechanism 3, and a petri dish storage rack 4 are sequentially arranged. An operating table 5 is located above the petri dish conveying mechanism 3. The petri dish rack 2 is used to store untreated petri dishes, and the petri dish storage rack 4 is used to store treated petri dishes. A petri dish ejection mechanism 6, which cooperates with the petri dish rack 2, is located on the base 1. A petri dish lifting mechanism 7 is located below the petri dish storage rack 4. The petri dish ejection mechanism 6 and the petri dish lifting mechanism 7 cooperate with the petri dish conveying mechanism 3, respectively. A linear displacement assembly 8, parallel to the operating table 5, is located on the base 1. The moving end of the linear displacement assembly 8 is connected to a first frame 9 and a second frame 10, respectively. A petri dish transport mechanism 11 and a test tube transport mechanism 12 are slidably connected to the first frame 9, and an inoculation loop streaking mechanism 13 is slidably connected to the second frame 10. A test tube rack 14 and a test tube clamping mechanism 15 are located adjacent to the operating table 5.
[0025] Specifically, several culture dishes to be processed are stacked on the culture dish rack 2. The culture dish ejection mechanism 6 separates the bottom culture dish on the culture dish rack 2 from the other culture dishes. The culture dish conveying mechanism 3 conveys the separated individual culture dish to the operating table 5. The culture dish handling mechanism 11 moves over to open the cap of the culture dish. After opening, the culture dish waits on the operating table 5 for the subsequent streaking operation. At the same time, the test tube handling mechanism 12 picks up the test tube to be tested from the test tube rack 14, moves it to the test tube holder and opens the cap. The inoculation loop streaking mechanism 13 moves above the test tube to pick up the sample, and then moves above the culture dish to streak it. After the culture dish is streaked, the culture dish conveying mechanism 3 moves it along the operating table 5 to the culture dish storage rack 4. Then, the culture dish lifting mechanism 7 lifts the culture dish upwards and stores it in the culture dish storage rack 4.
[0026] The petri dish placement rack 2, petri dish conveying mechanism 3, and petri dish storage rack 4 are arranged sequentially along the base 1, forming a linear working path and a complete closed-loop process. This shortens the movement path of the petri dishes during the entire marking process and improves the processing efficiency. The compact and reasonable layout reduces the equipment's footprint. The coordinated operation of the petri dish ejection mechanism 6, petri dish lifting mechanism 7, and petri dish conveying mechanism 3 enables automatic loading, feeding, and unloading of petri dishes, improving the automation level of the equipment.
[0027] Please see Figure 3 Specifically, a first displacement component is horizontally mounted on the first frame 9. The petri dish transport mechanism 11 includes a first support 1101 and a first lifting unit 1102 connected to the moving end of the first displacement component. The first support 1101 is connected to the first lifting unit 1102, and the output end of the first lifting unit 1102 is provided with a transport gripper 1103 for transporting and opening petri dishes. In this embodiment, the first lifting unit 1102 is a drive device including but not limited to a cylinder or a linear motor. The transport gripper 1103 can perform operations such as gripping, transporting, transferring, and opening petri dishes, improving the processing efficiency of petri dishes.
[0028] Specifically, the petri dish storage rack 4 includes a top plate and a bottom plate arranged sequentially, and multiple connecting rods disposed between the top and bottom plates. Multiple storage compartments for petri dishes are formed between the top and bottom plates via the connecting rods. The bottom plate has multiple circular grooves corresponding to the storage compartments. Multiple baffles are circumferentially connected to the edges of the circular grooves to prevent the petri dishes from falling off. The petri dish lifting mechanism 7 includes a petri dish lifting unit disposed on the base 1 and a push rod disposed on the output end of the petri dish lifting unit. The push rod pushes the processed petri dishes onto the bottom plate through the circular grooves. In this embodiment, there are two push rods, symmetrically arranged on the output end of the petri dish lifting unit, to prevent the petri dishes from tilting during the lifting process. The petri dish lifting unit is a drive device including, but not limited to, a cylinder or a linear motor.
[0029] In this embodiment, both the bottom of the petri dish placement rack 2 and the petri dish storage rack 4 are equipped with a turntable mechanism. The turntable mechanism drives the petri dish placement rack 2 and the petri dish storage rack 4 to rotate. This is existing technology and will not be described in detail here.
[0030] Furthermore, a labeling mechanism 16 is provided adjacent to the operating table 5 to cooperate with the petri dish transport mechanism 11. In this embodiment, the labeling mechanism 16 includes a label printing component and a label suction component arranged adjacent to each other. The label printing component includes a label roll and a label printer. One end of the label roll is connected to the label printer, and the paper outlet of the label printer horizontally pushes out the label. The label suction component includes a movable labeling platform, which is provided with suction cups for adsorbing the labels. This is prior art and will not be described in detail here.
[0031] The labeling process for the petri dishes is as follows: The petri dish ejection mechanism 6, in conjunction with the petri dish conveying mechanism 3, conveys the lowest petri dish in the petri dish placement rack 2 to the operating table 5. Simultaneously, the label printer horizontally ejects the corresponding printed label, which is then adsorbed onto the labeling platform. The petri dish transport mechanism 11 moves above the ejected petri dish to grasp it, causing the petri dish to fall onto the label on the labeling platform, thus labeling the bottom of the petri dish. After labeling, the petri dish transport mechanism 11 places the labeled petri dish back onto the operating table 5 and performs the opening operation.
[0032] Please see Figure 3 Specifically, the test tube transport mechanism 12 includes a second support 1201 connected to the moving end of the first displacement component, a rotating unit 1205, and a second lifting unit 1202. The second support 1201 is connected to the second lifting unit 1202. The output end of the second lifting unit 1202 is connected to a third support 1203. A clamping gripper 1204 is rotatably connected to the bottom of the third support 1203. The rotating unit 1205 is fixed on the third support 1203, and its output end is connected to the clamping gripper 1204. In this embodiment, the second lifting unit 1202 is a drive device including but not limited to a cylinder or a linear motor.
[0033] In use, the test tube transport mechanism 12 picks up the test tube, transports it to the test tube clamping mechanism 15, and opens the test tube. If the test tube contains a sample, the test tube transport mechanism 12 removes the test tube cap along with the cap, and then the inoculation loop streaking mechanism 13 moves above the opened test tube to collect the sample. If a swab is inserted into the test tube, the swab is carried by the test tube transport mechanism 12 to the operating table 5 along with the test tube cap. At this time, the rotating unit 1205 is activated, and the clamping gripper 1204 rotates the swab synchronously to a suitable streaking angle to streak the culture dish on the operating table 5. The test tube transport mechanism 12 can not only transport and open the test tube, and cooperate with the inoculation loop streaking mechanism 13 to complete the sample collection and streaking operations, but also use the swab for independent streaking, thus improving the applicability of this device.
[0034] Specifically, the second frame 10 is equipped with a second displacement assembly; the inoculation loop marking mechanism 13 includes an inoculation loop lifting unit connected to the moving end of the second displacement assembly and an inoculation loop disposed on the output end of the inoculation loop lifting unit, the inoculation loop cooperating with the test tube clamping mechanism 15. An infrared sterilizer 17 is also provided below the second frame 10 for sterilizing the inoculation loop. In this embodiment, the inoculation loop lifting unit is, but is not limited to, a drive device such as a cylinder or a linear motor.
[0035] Specifically, the linear displacement assembly 8 includes a linear guide rail mounted on the base 1, a driving wheel and a driven wheel mounted at both ends of the linear guide rail, and two sliders slidably connected to the linear guide rail. The driving wheel and the driven wheel are driven by a synchronous belt. The shaft of the driving wheel is connected to a drive motor, and the synchronous belt is connected to the two sliders. The two sliders are respectively connected to two supports, and the two supports are respectively connected to the first frame 9 and the second frame 10. This is prior art and will not be described in detail here.
[0036] Specifically, the petri dish conveying mechanism 3 includes a conveying displacement component disposed below the operating table 5 and an adsorption unit disposed on the moving end of the conveying displacement component. The output end of the adsorption unit is provided with a suction cup, which slides in cooperation with the operating table 5 and the petri dish placement rack 2. In this embodiment, both the top surface of the operating table 5 and the bottom plate of the petri dish placement rack 2 are provided with sliding grooves. The suction cup adsorbs and drives the petri dish to move through the sliding grooves. The adsorption unit is a driving device including but not limited to a cylinder or a linear motor.
[0037] Specifically, the petri dish ejection mechanism 6 includes a petri dish lifting assembly 601 disposed below the petri dish placement rack 2 and a petri dish clamp 602 disposed adjacent to the petri dish placement rack 2. The petri dish lifting assembly 601 includes a petri dish lifting unit disposed on the base 1 and a push rod disposed on the output end of the petri dish lifting unit; the push rod cooperates with the petri dish placement rack 2 to lift the petri dish, and the petri dish clamp 602 cooperates with the push rod to clamp part of the petri dish. In this embodiment, the petri dish lifting unit is a drive device including but not limited to a cylinder or a linear motor.
[0038] The process of ejecting the culture dishes is as follows: The culture dish lifting unit is activated, driving the push rod upward to lift the culture dishes on the culture dish placement rack 2 until the height of the second-to-last culture dish from top to bottom corresponds to the height of the culture dish holder 602. At this time, the culture dish holder 602 is activated, fixing all culture dishes except the bottom one by clamping the second-to-last culture dish. The culture dish lifting unit drives the push rod downward, and the bottom culture dish falls together, separating from the other culture dishes. The suction unit is activated, and the suction cup contacts and adheres to the bottom culture dish, pulling the culture dish away from the culture dish placement rack 2.
[0039] In this embodiment, the moving end of the second displacement component is also connected to a pipetting pump mechanism 18. The pipetting pump mechanism 18 includes a pipetting pump lifting unit connected to the moving end of the second displacement component and a pipetting pump disposed at the output end of the pipetting pump lifting unit. Below the pipetting pump mechanism 18, there is a pipetting tube holder 19 and a digestive fluid storage cup 20 that cooperate with it. The pipetting tube holder 19 is provided with multiple pipettes, and the bottom of the test tube holder 14 is provided with a test tube shaking mechanism. The pipetting pump lifting unit is a drive device including but not limited to a cylinder or a linear motor. When the sample in the test tube is sputum, the pipetting pump mechanism 18 can add digestive fluid to it to dilute the sputum sample and improve the applicability of the device.
[0040] In this embodiment, the first displacement component, the second displacement component, the rotation unit 1205, the transmission displacement component, and the linear displacement component 8 have similar structures, all being belt drive mechanisms composed of a driving wheel, a driven wheel, a synchronous belt, and a drive motor. The driven wheel of the rotation unit 1205 is connected to the clamping gripper 1204 via a rotating shaft, driving the clamping gripper 1204 to rotate at a certain angle. All of the above belt drive mechanisms are existing technology and will not be described in detail here.
[0041] The working process of this utility model is as follows: The petri dish ejection mechanism 6 separates the lowest petri dish on the petri dish placement rack 2 from the other petri dishes. The petri dish conveying mechanism 3 conveys the separated individual petri dishes to the operating table 5. The petri dish transporting mechanism 11 moves over to open the cap. At the same time, the test tube transporting mechanism 12 picks up the test tube to be tested from the test tube placement rack 14, transports it to the test tube holder and opens the cap. The inoculation loop streaking mechanism 13 moves above the test tube to pick up the sample, and then moves above the petri dish to streak it. After the petri dish is streaked, the petri dish conveying mechanism 3 drives it to continue sliding along the operating table 5 to the petri dish storage rack 4. Then, the petri dish lifting mechanism 7 lifts the petri dish upwards and stores it in the petri dish storage rack 4.
[0042] In this invention, the petri dish placement rack 2, the petri dish conveying mechanism 3, and the petri dish storage rack 4 are arranged sequentially along the base 1, forming a linear working path and a complete closed-loop process. This shortens the movement path of the petri dishes during the entire streaking process and improves the processing efficiency. The overall layout of the device is compact and reasonable, avoiding mutual interference, simplifying the overall structure, and reducing the equipment's footprint. The coordinated operation of the petri dish ejection mechanism 6, the petri dish lifting mechanism 7, and the petri dish conveying mechanism 3 enables automatic loading, feeding, and unloading of petri dishes, improving the automation level of the equipment. The test tube handling mechanism 12 works in conjunction with the inoculation loop streaking mechanism 13 to complete operations such as test tube placement, cap opening, sample dipping, or swab streaking, all without manual intervention, saving labor costs.
