Description

Technical Field

[0001] This application relates to the field of microbial instrument technology, and more specifically, to a device for pushing, uncapping, and rotating culture dishes. Background Technology

[0002] In modern medical testing and biopharmaceutical fields, clinical microbiology testing is an important means for medical institutions in disease diagnosis and other fields. The efficiency and quality of the microbial sample processing directly determine the accuracy of subsequent tests, making automated microbial sample processing crucial.

[0003] However, existing microbial sample processing devices still have many problems, mainly in the petri dish delivery mechanism. The current petri dish delivery mechanism has a low degree of automation; it is not only structurally complex but also functionally limited, only capable of basic petri dish transport. Most common petri dish delivery mechanisms involve pushing the petri dishes out from above a rack and then using a conveyor belt. However, in actual use, due to factors such as the stacking state of the petri dishes within the silo and uneven force during delivery, petri dishes are prone to jamming, interrupting subsequent steps such as opening the lid and observation, thus affecting overall work efficiency. Utility Model Content

[0004] To address the aforementioned problems, the present invention provides a petri dish pushing, uncapping, and rotating device, which solves the problems of complex structure, limited function, and unstable pushing in existing petri dish pushing mechanisms. The device includes a base, a worktable, and a petri dish rack. A linear displacement mechanism is located below the worktable, and a petri dish pushing mechanism that moves the petri dishes is located below the petri dish rack. The petri dish pushing mechanism includes a lifting drive assembly connected to the moving end of the linear displacement mechanism, a rotation drive assembly connected to the output end of the lifting drive assembly, and a suction cup for adsorbing the petri dishes at the output end of the rotation drive assembly. A first groove cooperating with the suction cup is provided on the surface of the worktable, a petri dish cap opener is located above the first groove, and a clamping mechanism is located above the cap opener. The clamping mechanism cooperates with the petri dish pushing mechanism to clamp the petri dish above the adsorbed petri dish.

[0005] Preferably, the petri dish opener has a structure that is open at both ends and open at the bottom. The petri dish opener has opening grooves with inclined bottoms on both sides, and the height of the bottom of the opening grooves gradually increases along the direction of movement of the petri dish being adsorbed.

[0006] Preferably, the bottom surface of the opening groove near the end of the petri dish placement rack is a slope.

[0007] Preferably, the lifting drive assembly includes a fixed plate connected to the linear displacement mechanism and a lifting drive motor disposed on the bottom surface of the fixed plate. The fixed plate is provided with a through hole, and the output shaft of the lifting drive motor is connected to a support base through the through hole. The rotation drive assembly includes a rotation drive motor disposed on the support base. The output shaft of the rotation drive motor is connected to a suction cup. The suction cup cooperates with the lowest culture dish on the culture dish placement rack to drive the adsorbed culture dish to move or rotate.

[0008] Preferably, the clamping mechanism includes a slide and a sliding block disposed at the top of the petri dish opener. The sliding block is slidably connected to the slide. A gripper is provided on the side of the sliding block near the petri dish holder. The gripper cooperates with the petri dish pushing mechanism to clamp the petri dish. The sliding block is connected to a gripper driving assembly that drives its sliding.

[0009] Preferably, the gripper drive assembly includes a gripper drive fixing bracket disposed on the bottom surface of the base and a gripper drive unit disposed on the gripper drive fixing bracket. The output shaft of the gripper drive unit is connected to a vertically arranged lifting rod. A rotating block is rotatably connected to the end of the lifting rod, and the other end of the rotating block is rotatably connected to the side of the sliding block.

[0010] Preferably, the linear displacement mechanism includes a vertical plate mounted on a base, a horizontal slide rail on one side of the vertical plate, a connecting block slidably connected to the slide rail, and the connecting block being connected to the side wall of the lifting drive motor; and a horizontal drive component that drives the lifting drive component to slide along the slide rail on the other side of the vertical plate.

[0011] Preferably, the horizontal drive assembly includes a horizontal drive motor mounted on the base, a drive wheel and a driven wheel respectively mounted at both ends of the vertical plate, the drive wheel and the driven wheel being connected by a synchronous belt drive, the output shaft of the horizontal drive motor being connected to the drive wheel, a fixing block being connected to the synchronous belt, and the fixing block being connected to the fixing plate.

[0012] Preferably, the petri dish rack includes a top plate and a bottom plate corresponding to each other. The top plate has a circular notch, and the bottom plate has an opening that cooperates with the petri dish pushing mechanism. The top plate and the bottom plate are connected by multiple rack connecting rods to form multiple petri dish placement spaces. A rack fixing bracket is provided on the base, and a rack rotation drive assembly for driving the petri dish rack to rotate is provided below the bottom plate. The rack fixing bracket is connected to the rack rotation drive assembly.

[0013] Preferably, the lifting drive motor is a through-shaft stepper motor, and the base is provided with a second slide groove corresponding to the linear displacement mechanism, the second slide groove cooperating with the lifting drive motor.

[0014] The beneficial effects of this invention are as follows: Through the cooperation of the petri dish pushing mechanism and the clamping mechanism, the petri dishes are sequentially pushed out from below the petri dish rack. Compared to pushing the petri dishes out from above, the travel distance of the pushing mechanism is significantly reduced, avoiding extra time consumption due to variations in travel distance. Furthermore, regardless of which petri dish is being retrieved, the travel distance of the pushing mechanism remains constant. This fixed travel distance makes the operation of the pushing mechanism more stable and orderly, improving the continuity and efficiency of the entire process. Each mechanism is sequentially arranged on the base. Through the coordinated operation of these mechanisms, automatic pushing, capping, and rotation of the petri dishes are achieved, resulting in a high degree of automation and reducing errors and risks associated with manual operation. The entire device has a compact structure, a reasonable layout, and a small footprint, making it suitable for various working environments. Attached Figure Description

Therefore, they should not be construed as limitations on this application.

[0027] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0028] The present application will now describe a petri dish pushing, uncapping, and rotating device provided in an embodiment of this application.

[0029] Please see Figures 1 to 4The petri dish pushing, uncapping, and rotating device includes a base 1, a workbench 2, and a petri dish rack 3 on the base 1. Several petri dishes are placed on the petri dish rack 3. A linear displacement mechanism 4 is located below the workbench 2, and a petri dish pushing mechanism 5, which moves the petri dishes, is located below the petri dish rack 3. The petri dish pushing mechanism 5 includes a lifting drive assembly 51 connected to the moving end of the linear displacement mechanism 4; a rotation drive assembly 52 is connected to the output end of the lifting drive assembly 51, and a suction cup 53 for adsorbing petri dishes is located at the output end of the rotation drive assembly 52. ​​A first groove 21, which mates with the suction cup 53, is provided on the surface of the workbench 2. A petri dish cap opener 6 is located above the first groove 21, and a clamping mechanism 7 is located above the petri dish cap opener 6. The clamping mechanism 7 mates with the petri dish pushing mechanism 5 to clamp the petri dish above the adsorbed petri dish.

[0030] Specifically, in use, the lifting drive assembly 51 is activated first, driving the rotation drive assembly 52 and the suction cup 53 to rise. The suction cup 53 rises to the petri dish placement rack 3 and attaches to the bottommost petri dish. The lifting drive assembly 51 continues to rise until the height of the second-to-last petri dish corresponds to the height of the clamping mechanism 7. At this point, the clamping mechanism 7 is activated, approaching and clamping the second-to-last petri dish. Once the second-to-last petri dish is secured by the clamping mechanism 7, the lifting drive assembly 51 begins to descend, and the suction cup 53 and the attached petri dish descend together to the base plate 32 of the petri dish placement rack 3. Subsequently, the petri dish pushing mechanism 5 moves horizontally under the drive of the linear displacement mechanism 4. During this process, the suction cup 53 slides horizontally on the worktable 2 via the first groove 21 on the surface of the worktable 2, entering the petri dish opener 6. As the petri dish moves, the petri dish opener 6 opens the petri dish. The end of workbench 2 is designated as an observation point for the petri dishes. When a petri dish moves to this observation point, the rotation drive assembly 52 is activated, causing the uncapped petri dish to rotate at a certain angle, allowing the operator to observe the contents of the petri dish from different angles. The petri dishes are sequentially pushed out from below the petri dish rack 3 via the cooperation of the petri dish pushing mechanism 5 and the clamping mechanism 7. Compared to pushing the petri dish from above, the travel distance of the petri dish pushing mechanism 5 is significantly reduced, avoiding additional time consumption due to variations in travel distance. Furthermore, the travel distance of the petri dish pushing mechanism 5 remains constant regardless of which petri dish is being retrieved. This fixed travel distance ensures more stable and orderly operation of the petri dish pushing mechanism 5, improving the continuity and efficiency of the entire process. Through the coordinated operation of various mechanisms, automatic pushing, uncapping, and rotation of petri dishes are achieved, resulting in a high degree of automation and reducing errors and risks associated with manual operation. The entire device has a compact structure, reasonable layout, and small footprint, making it suitable for various working environments.

[0031] Please see Figure 1 and Figure 3Furthermore, the petri dish opener 6 has a structure that is open at both ends and has an open bottom. The petri dish opener 6 has opening grooves 61 with inclined bottoms on both sides. The height of the bottom of the opening grooves 61 gradually increases along the direction of the petri dish being adsorbed. Specifically, the petri dish pushing mechanism 5 drives the petri dish into the petri dish opener 6. The lid of the petri dish first contacts the bottom of the lower opening groove 61. As the petri dish continues to go deeper, the height of the bottom of the opening groove 61 gradually increases, and the lid of the petri dish is gradually pushed upwards along the inclined opening groove 61. When the petri dish has completely passed through the petri dish opener 6, the lid is successfully lifted and detached from the petri dish, achieving automatic opening. Using the opening grooves 61 to lift and achieve automatic opening is simpler in structure and lower in manufacturing cost compared to manual or robotic opening methods; the opening process is smooth and less likely to damage the petri dish and internal samples.

[0032] Furthermore, the bottom surface of the opening groove 61 near the end of the petri dish holder 3 is a slope 62. Specifically, the slope 62 guides the petri dish. When the petri dish moves toward the petri dish opener 6, the slope 62 guides the petri dish smoothly into the opening groove 61, avoiding collisions or jamming between the petri dish and the end surface of the opening groove 61, making the opening process of the petri dish smoother and more stable.

[0033] Please see Figure 1 and Figure 4 Specifically, the lifting drive assembly 51 includes a fixed plate 511 connected to the linear displacement mechanism 4 and a lifting drive motor 512 disposed on the bottom surface of the fixed plate 511. The fixed plate 511 has a through hole, and the output shaft of the lifting drive motor 512 is connected to a support base 514 through the through hole, driving the support base 514 to rise or fall. The rotation drive assembly 52 includes a rotation drive motor 521 disposed on the support base 514. The output shaft of the rotation drive motor 521 is connected to a suction cup 53. The suction cup 53 cooperates with the lowest culture dish on the culture dish placement rack 3, driving the adsorbed culture dish to move or rotate.

[0034] Please see Figure 2 and Figure 4 In this embodiment, the lifting drive motor 512 is a through-shaft stepper motor, and the base 1 is provided with a second slide groove 11 corresponding to the linear displacement mechanism 4. The second slide groove 11 cooperates with the lifting drive motor 512.

[0035] Specifically, sleeves fixed to the fixing plate 511 are symmetrically arranged on both sides of the lifting drive motor 512. Guide rods are arranged in the vertical direction inside the sleeves. The support seat 514 is lifted and lowered along the guide rods under the drive of the lifting drive motor 512, which improves the stability of the support seat 514 when it moves.

[0036] Please see Figure 2 and Figure 7Furthermore, the clamping mechanism 7 includes a slide 71 and a sliding block 72 disposed at the top of the petri dish opener 6. The sliding block 72 is slidably connected to the slide 71. The side of the sliding block 72 near the petri dish holder 3 is provided with a gripper 73. The gripper 73 cooperates with the petri dish pushing mechanism 5 to clamp the petri dish. The sliding block 72 is connected to a gripper driving assembly 74 that drives it to slide.

[0037] Furthermore, the gripper drive assembly 74 includes a gripper drive fixing bracket 741 disposed on the bottom surface of the base 1 and a gripper drive unit 742 disposed on the gripper drive fixing bracket 741. The gripper drive unit 742 is, but is not limited to, a screw motor, a cylinder, or other structures. In this embodiment, the gripper drive unit 742 is a through-shaft stepper motor. The output shaft of the gripper drive unit 742 is connected to a vertically arranged lifting rod 743. A rotating block 744 is rotatably connected to the end of the lifting rod 743, and the other end of the rotating block 744 is rotatably connected to the side of the sliding block 72. Specifically, the gripper drive unit 742 drives the lifting rod 743 to rise or fall vertically. The rotating block 744 rotates as the lifting rod 743 moves, converting the vertical linear motion of the lifting rod 743 into the horizontal linear motion of the sliding block 72 on the slide rail 71 during rotation. When the lifting rod 743 rises, the rotating block 744 pushes the sliding block 72 to move closer to the culture dish placement rack 3, causing the gripper 73 to approach the second-to-last culture dish and clamp it; when the lifting rod 743 falls, the rotating block 744 pulls the sliding block 72 to move away from the culture dish placement rack 3, releasing the clamped culture dish. At this time, the second-to-last culture dish falls back to the bottom plate 32 and becomes the last culture dish.

[0038] Please see Figure 1 , Figure 5 and Figure 6 Furthermore, the linear displacement mechanism 4 includes a vertical plate 41 mounted on the base 1. A slide rail 42 is horizontally mounted on one side of the vertical plate 41, and a connecting block 43 is slidably connected to the slide rail 42. The connecting block 43 is connected to the side wall of the lifting drive motor 512. A horizontal drive assembly 44 is mounted on the other side of the vertical plate 41 to drive the lifting drive assembly 51 to slide along the slide rail 42.

[0039] Specifically, the horizontal drive assembly 44 includes a horizontal drive motor 441 mounted on the base 1, a drive wheel 442 and a driven wheel 443 respectively mounted at both ends of the upright plate 41. The drive wheel 442 and the driven wheel 443 are connected by a synchronous belt 444. The output shaft of the horizontal drive motor 441 is connected to the drive wheel 442. A fixing block 513 is connected to the synchronous belt 444 and is connected to the fixing plate 511. The output shaft of the horizontal drive motor 441 drives the drive wheel 442 to rotate, which in turn drives the driven wheel 443 to rotate synchronously via the synchronous belt 444. During the movement of the synchronous belt 444, the fixing block 513 connected to the synchronous belt 444 moves along with the synchronous belt 444, thereby driving the petri dish pushing mechanism 5 to move horizontally along the slide rail 42 via the fixing plate 511, and the adsorbed petri dishes move synchronously.

[0040] Please see Figure 1 and Figure 8 Specifically, the petri dish rack 3 includes a top plate 31 and a bottom plate 32 corresponding to each other. The top plate 31 has a circular notch, and the bottom plate 32 has an opening that cooperates with the petri dish pushing mechanism 5. The top plate 31 and the bottom plate 32 are connected by multiple rack connecting rods 33 to form multiple petri dish placement spaces. The base 1 is provided with a rack fixing bracket 34, and the bottom plate 32 is provided with a rack rotation drive assembly 35 that drives the petri dish rack 3 to rotate. The rack fixing bracket 34 is connected to the rack rotation drive assembly 35.

[0041] The working process of this utility model is as follows: In use, the lifting drive assembly 51 is activated first, driving the rotation drive assembly 52 and the suction cup 53 to rise and adhere to the bottommost culture dish. The lifting drive assembly 51 continues to rise until the height of the second-to-last culture dish corresponds to the height of the clamping mechanism 7. At this point, the clamping mechanism 7 is activated, approaching and clamping the second-to-last culture dish. After the second-to-last culture dish is fixed by the clamping mechanism 7, the lifting drive assembly 51 begins to descend, and the suction cup 53 and the adhered culture dish descend together to the bottom plate 32 of the culture dish placement rack 3. Subsequently, the culture dish pushing mechanism 5 moves horizontally under the drive of the linear displacement mechanism 4, entering the culture dish opener 6. As the culture dish moves, the culture dish opener 6 opens the culture dish. When the culture dish moves to the observation point, the rotation drive assembly 52 is activated, causing the uncapped culture dish to rotate at a certain angle.

[0042] In this invention, the petri dishes are sequentially pushed out from below the petri dish rack 3 via the cooperation of the petri dish pushing mechanism 5 and the clamping mechanism 7. Compared to pushing the petri dish rack 3 out from above, the travel distance of the petri dish pushing mechanism 5 is significantly reduced, avoiding additional time consumption caused by changes in travel distance. Furthermore, the travel distance of the petri dish pushing mechanism 5 remains the same regardless of which petri dish is being picked up. This fixed travel distance makes the operation of the petri dish pushing mechanism 5 more stable and orderly, improving the continuity and efficiency of the entire process. Each mechanism is sequentially arranged on the base 1. Through the coordinated operation of these mechanisms, automatic pushing, uncapping, and rotating of the petri dishes are achieved, resulting in a high degree of automation and reducing errors and risks associated with manual operation. The entire device has a compact structure, a reasonable layout, and a small footprint, making it suitable for various working environments.

[0043] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. 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.
