Description

Technical Field

[0001] This application relates to the field of microbial processing device technology, and more specifically, to a multi-type petri dish inoculation and labeling device. Background Technology

[0002] With the development and application of automation technology in the field of microbial experiments, traditional manual processing of petri dishes is gradually being replaced by automated devices. Manual processing of petri dishes is inefficient and prone to introducing contamination. Currently available automated microbial processing devices have improved these problems, but some issues still exist in practical applications.

[0003] In existing microbial processing devices, most petri dish handling grippers are fixed structures designed for single-size or single-type petri dishes, with non-adjustable clamping spacing, only suitable for specific petri dishes. While a few petri dish handling grippers are adjustable, manual replacement of clamping components is required. This results in poor compatibility of microbial processing devices with multiple sizes and types of petri dishes, limiting their applicability. Different clamping components need to be replaced for different types of petri dishes, increasing manufacturing costs and impacting continuous operation efficiency, making it difficult to meet the current laboratory requirements for efficient and highly compatible processing of multiple types of petri dishes.

[0004] In addition, the existing gripper's clamping components lack a buffer structure on the grippers when clamping, which can easily lead to damage to the culture dish if the clamping force is not properly controlled. Furthermore, the rigid clamping cannot adapt to the differences in the edges of the culture dish, which may result in unstable clamping and the culture dish falling off. Utility Model Content

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] The present application will now describe a multi-type culture dish inoculation and labeling device provided in the embodiments of this application.

[0023] Please see Figures 1 to 4The multi-type petri dish inoculation and labeling device includes a base 1 and a worktable 2 mounted on the base 1. The worktable 2 is used to place petri dishes and perform inoculation operations. A first frame 3 is provided in front of the worktable 2. An inoculation loop streaking mechanism 4 and a petri dish transporting mechanism 5 are slidably connected on the first frame 3. A labeling mechanism 18 is provided on the adjacent side of the worktable 2. Specifically, the inoculation loop streaking mechanism 4 slides above the worktable 2 to streak the petri dish. Then, the petri dish is transported by the petri dish transporting mechanism 5 to the labeling mechanism 18, where the labeling mechanism 18 affixes a label to the bottom of the petri dish. The petri dish transporting mechanism 5 includes a transport gripper assembly 501 located at its output end. The transport gripper assembly 501 includes a mounting plate 5011, a clamping plate driving unit 5012, and two clamping plates 5013. The mounting plate 5011 is connected to the output end of the petri dish transporting mechanism 5 and the clamping plate driving unit 5012, respectively. The petri dish transporting mechanism 5 drives the mounting plate 5011 and the clamping plate driving unit 5012 to move. Two clamping plates 5013 are symmetrically distributed on both sides of the clamping plate driving unit 5012 and are slidably connected to the mounting plate 5011. The output end of the clamping plate driving unit 5012 is connected to the two clamping plates 5013 respectively. The clamping plate driving unit 5012 drives the two clamping plates 5013 to slide synchronously in opposite directions along the mounting plate 5011. The operator pre-sets the spacing between the two clamping plates 5013 according to the size and type of the petri dish. The control system adjusts the spacing between the two clamping plates 5013 through the clamping plate driving unit 5012 to adapt to petri dishes of different sizes and types. There is no need to replace the special gripper, which reduces the manufacturing cost of the device and improves the applicability and processing efficiency of the device. The clamping plate 5013 is provided with a connecting shaft 5014, and the connecting shaft 5014 is provided with a gripper 5015. A spring 5016 sleeved on the connecting shaft 5014 abuts between the clamping plate 5013 and the gripper 5015. Specifically, the spring 5016 provides elastic cushioning to the culture dish during clamping, preventing the gripper 5015 from damaging the culture dish, protecting the integrity of the sample, and reducing experimental errors. At the same time, the elastic deformation of the spring 5016 allows the gripper 5015 to passively adapt to culture dishes within a certain size range, further improving the applicability of the device.

[0024] In this embodiment, the clamping plate driving unit 5012 is a forward and reverse lead screw motor structure. In other embodiments, the clamping plate driving unit 5012 may also be a driving device including but not limited to a synchronous belt pulley transmission structure and a gear and rack transmission structure, which can enable the two clamping plates 5013 to move synchronously in opposite directions. The forward and reverse lead screw motor structure, the synchronous belt pulley transmission structure, and the gear and rack transmission structure are all existing technologies and will not be described in detail here.

[0025] Furthermore, a petri dish rack 6 is provided on the base 1, and several petri dishes are stacked on the petri dish rack 6; a lifting mechanism 7 is provided below the petri dish rack 6, and a petri dish holder 8 is provided on the adjacent side of the petri dish rack 6. The lifting mechanism 7 and the petri dish holder 8 cooperate to separate individual petri dishes; a petri dish conveying mechanism 9 is provided below the petri dish rack 6 and the worktable 2. A sliding groove 201 is provided on the worktable 2 to cooperate with the petri dish conveying mechanism 9. The petri dish conveying mechanism 9 conveys the separated individual petri dishes to the worktable 2.

[0026] Please see Figure 2 and Figure 4 Specifically, the lifting mechanism 7 includes a lifting drive unit 701 mounted on the base 1 and a push rod 702 mounted on the output end of the lifting drive unit 701. The push rod 702 cooperates with the culture dish holder 6 to lift the culture dish, and the culture dish holder 8 cooperates with the push rod 702 to hold part of the culture dish. The lifting mechanism 7 and the culture dish holder 8 work together to achieve automatic separation of individual culture dishes, eliminating the need for manual separation, reducing the risk of contamination, and preventing the culture dishes from being bumped or knocked.

[0027] Specifically, the petri dish conveying mechanism 9 includes a conveying displacement component 901 disposed below the worktable 2 and an adsorption driving unit 902 disposed on the moving end of the conveying displacement component 901. The output end of the adsorption driving unit 902 is provided with a suction cup, which slides in cooperation with the worktable 2 and the petri dish placement rack 6. In this embodiment, the conveying displacement component 901 is a synchronous belt pulley drive structure, which will not be described in detail here.

[0028] In use, the lifting drive unit 701 is activated, driving the push rod 702 to rise. The push rod 702 passes through the bottom plate of the culture dish placement rack 6 and lifts the culture dish until the height of the second-to-last culture dish from the top is aligned with the culture dish holder 8. At this time, the culture dish holder 8 is activated, approaching the lifted culture dish and cooperating with the push rod 702 to hold the second-to-last culture dish and the culture dishes above it, leaving only the bottom culture dish on the push rod 702. After the push rod 702 returns to its original position, the single culture dish falls onto the bottom plate of the culture dish placement rack 6, completing the separation of the single culture dish. Immediately afterwards, the culture dish conveying mechanism 9 is activated. The conveying displacement component 901 drives the adsorption drive unit 902 to move to the separated single culture dish. The adsorption drive unit 902 adsorbs the culture dish through a suction cup. Under the action of the conveying displacement component 901, the suction cup carries the culture dish into the worktable 2 and continues to slide along the surface of the worktable 2 until it moves to the inoculation and streaking area. The culture dish waits on the worktable 2 for the subsequent inoculation and streaking operation.

[0029] Please see Figure 2Furthermore, the first frame 3 is horizontally provided with a first guide rail along its length, and a first displacement mechanism 10 and a second displacement mechanism 11 arranged coaxially vertically. The moving end of the first displacement mechanism 10 is connected to the petri dish transport mechanism 5; the moving end of the second displacement mechanism 11 is connected to the inoculation loop streaking mechanism 4, which can control the position adjustment of the petri dish transport mechanism 5 and the inoculation loop streaking mechanism 4 respectively. Specifically, the first displacement mechanism 10 includes a first drive unit, a drive wheel, and a driven wheel disposed on the first frame 3. The drive wheel and the driven wheel are driven by a synchronous belt, and the output end of the first drive unit is connected to the drive wheel. A first slider is slidably connected to the first guide rail, and the first slider is connected to the synchronous belt and the petri dish transport mechanism 5 respectively. In this embodiment, the second displacement mechanism 11 has a similar structure to the first displacement mechanism 10, both being synchronous belt pulley drive structures, which will not be described in detail here.

[0030] Please see Figure 2 and Figure 3 Specifically, the petri dish transport mechanism 5 includes a first support 502 connected to the moving end of the first displacement mechanism 10 and a petri dish transport drive unit 503 vertically disposed at the end of the first support 502. The output end of the petri dish transport drive unit 503 is connected to a mounting plate 5011. The petri dish transport drive unit 503 drives the transport gripper assembly 501 to move freely in the vertical direction via the mounting plate 5011. In this embodiment, the petri dish transport drive unit 503 is a drive device including but not limited to a cylinder.

[0031] Specifically, the inoculation loop marking mechanism 4 includes a second support connected to the moving end of the second displacement mechanism 11, an inoculation loop displacement assembly, and an inoculation loop drive unit. The second support is horizontally mounted with the inoculation loop displacement assembly, which is vertically distributed to the second displacement mechanism 11. The moving end of the inoculation loop displacement assembly is connected to the inoculation loop drive unit, and the output end of the inoculation loop drive unit is connected to the inoculation loop. An infrared sterilizer is located below the inoculation loop marking mechanism 4. With the cooperation of the second displacement mechanism 11 and the inoculation loop displacement assembly, the inoculation loop can move freely in the horizontal direction; under the action of the inoculation loop drive unit, the inoculation loop can move freely in the vertical direction. In this embodiment, the inoculation loop drive unit is a drive device including, but not limited to, a cylinder; the inoculation loop displacement assembly has a similar structure to the first displacement mechanism 10, both being synchronous belt pulley transmission structures, which will not be described in detail here.

[0032] Furthermore, a second frame 12 is provided on the base 1, which is perpendicular to the first frame 3. The second frame 12 is horizontally provided with a second guide rail and a third displacement mechanism 13 along its length. The moving end of the third displacement mechanism 13 is connected to a test tube transport mechanism 14. Below the test tube transport mechanism 14, a test tube rack 15, a barcode scanner 16, and a test tube holder 17 are arranged in sequence. The test tube holder 17 cooperates with the test tube transport mechanism 14 to hold the test tubes. The inoculation loop streaking mechanism 4 cooperates with the test tube holder 17 to pick up the sample.

[0033] Specifically, the test tube transport mechanism 14 includes a third support connected to the moving end of the third displacement mechanism 13, a test tube displacement component, and a test tube transport drive unit. The third support is horizontally mounted with test tube displacement components that are perpendicularly distributed to the third displacement mechanism 13. The moving end of the test tube displacement component is connected to the test tube transport drive unit, and the output end of the test tube transport drive unit is connected to a clamping gripper. In this embodiment, the test tube transport drive unit is a drive device including, but not limited to, a cylinder; the test tube displacement component has a similar structure to the first displacement mechanism 10, both being synchronous belt pulley transmission structures, which will not be described in detail here.

[0034] Before streaking the petri dish, the inoculation loop streaking mechanism 4 needs to first pick up a sample. The specific process is as follows: The third displacement mechanism 13 is activated first, driving the test tube transport mechanism 14 to move horizontally along the second frame 12 to directly above the test tube placement rack 15. After the test tube transport mechanism 14 picks up a single test tube, the third displacement mechanism 13 continues to move it to the barcode scanner 16. The barcode scanner 16 scans the barcode on the test tube to complete the sample information identification. The test tube transport mechanism 14 continues to move above the test tube holder 17 and releases the test tube, which is then fixed in place by the test tube holder 17. Subsequently, the inoculation loop streaking mechanism 4 moves above the test tube holder 17, inserts itself into the test tube to pick up the sample, and after the sample is picked up, the inoculation loop streaking mechanism 4 moves back to the workbench 2, ready to streak the petri dish. In this embodiment, the third displacement mechanism 13 and the first displacement mechanism 10 have similar structures, both being synchronous belt pulley drive structures, which will not be described in detail here.

[0035] In this embodiment, a cap opener 19 is provided at one end of the workbench 2 near the petri dish rack 6. The cap opener 19 is an open structure with both ends open, and inclined opening grooves are provided on the inner walls of both sides of the cap opener 19. The cap opener 19 cooperates with the petri dish conveying mechanism 9 to open the caps of individual petri dishes. Specifically, under the action of the conveying displacement component 901, the suction cup carries the petri dish into the workbench 2. During this process, the petri dish first enters the cap opener 19. As the petri dish moves horizontally, the cap of the petri dish is pushed upward along the inclined opening groove to complete the cap opening operation. After the cap is opened, the petri dish moves to the inoculation and streaking area under the action of the suction cup to wait for subsequent operations.

[0036] The working process of this utility model is as follows: The lifting drive unit 701 is activated, driving the push rod 702 to lift the culture dish upwards. The culture dish holder 8 is activated, cooperating with the push rod 702 to hold the second-to-last culture dish and the culture dish above it. After the push rod 702 resets, the lowest single culture dish falls onto the bottom plate of the culture dish placement rack 6, completing the separation of the single culture dish. Immediately afterwards, the conveying displacement component 901 drives the adsorption drive unit 902 to move to the separated single culture dish, adsorbing the culture dish through the suction cup. Under the action of the conveying displacement component 901, the suction cup carries the culture dish into the worktable 2. During this process, the culture dish first enters the cap opener 19, and the cap opening operation is completed as the culture dish moves horizontally. After the cap is opened, the culture dish continues to slide along the surface of the worktable 2 until it moves to the inoculation and streaking area, where the culture dish waits for the subsequent inoculation and streaking operation on the worktable 2.

[0037] The third displacement mechanism 13 is activated, moving the test tube transport mechanism 14 to directly above the test tube rack 15 and grabbing a single test tube. The test tube transport mechanism 14 then moves to the barcode scanner 16 for scanning. After sample information identification is completed, the test tube transport mechanism 14 continues to move above the test tube holder 17 and releases the test tube, which is then secured by the test tube holder 17. Subsequently, the second displacement mechanism 11 moves the inoculation loop streaking mechanism 4 to the infrared sterilizer for disinfection, and then moves it above the test tube holder 17. The inoculation loop dips the test tube in the sample. After sample dipping, the inoculation loop streaking mechanism 4 returns to the workbench 2 to perform streaking inoculation on waiting culture dishes.

[0038] After the marking operation is completed, the inoculation loop mechanism is removed, the first displacement mechanism 10 is activated, and the culture dish transport mechanism 5 is moved to the top of the marked culture dish. The culture dish transport mechanism 5 drives the transport gripper assembly 501 to clamp the culture dish and transport the marked culture dish to the labeling mechanism 18 for labeling.

[0039] In this invention, the handling gripper assembly 501 includes a clamping plate driving unit 5012 and two clamping plates 5013. The clamping plate driving unit 5012 drives the two clamping plates 5013 to slide synchronously in opposite directions. The operator pre-sets the spacing between the two clamping plates 5013 according to the size and type of the petri dish. The handling gripper assembly 501 adapts to different sizes and types of petri dishes by adjusting the spacing between the two clamping plates 5013, eliminating the need to replace dedicated grippers, reducing the manufacturing cost of the device, improving the applicability and processing efficiency of the device, and solving the problem that traditional petri dish handling grippers can only handle petri dishes of a single size. A spring 5016 abuts between the clamping plate 5013 and the gripper 5015, providing elastic cushioning during clamping to prevent the gripper 5015 from damaging the petri dish, protecting the sample integrity, and reducing experimental errors. Furthermore, the elastic deformation of the spring 5016 allows the gripper 5015 to passively adapt to petri dishes within a certain size range, further improving the applicability of the device. The various components of this device work together seamlessly, with a high degree of automation, and can meet the processing needs of various types of petri dishes, making it widely applicable.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
