Description

Technical Field

[0001] This utility model relates to the testing and analysis of microorganisms by measuring the physical properties of microbial colonies, and particularly to the fields of biological laboratory instruments and equipment, microbial detection and analysis instruments, specifically a cover-and-cover structure bracket and a stacked cover-and-cover structure lifting device. Background Technology

[0002] Petri dishes (also known as culture dishes or plates) are commonly used in microbiology experiments for culturing and observing microorganisms such as bacteria and mosses. A petri dish consists of two parts: a bottom and a lid. Both the bottom and the lid have a concave, hollow structure. Packaged petri dishes, or those in use, have their bottom embedded in the lid, forming a relatively sealed space. To fill this sealed space with material, the lid and bottom need to be separated; the material is first filled to the bottom, and then the lid is closed.

[0003] However, in the process of realizing this utility model, existing leveling equipment is based on large-scale filling lines, which requires a large production space and is not convenient for customized small-batch production. Specifically:

[0004] (1) The space utilization rate of the plate placement mechanism is low;

[0005] (2) Laboratory staff use manual pouring or peristaltic pumps to dispense the contents, which takes up staff time and requires a large area for cooling and drying.

[0006] (3) Using the existing dispensing instrument on the market, the humidity inside the dispensed culture dish is high and the lid produces a lot of water mist, which affects subsequent work. If the water mist is allowed to dissipate before the lid is put on, it is a problem to place dozens or even hundreds of lids under sterile conditions. Utility Model Content

[0041] III. Beneficial Effects

[0042] As can be seen from the above technical solution, the present invention has at least one of the following beneficial effects compared with the prior art:

[0043] (1) In this utility model, the flat dish holder is in the shape of a disc, the outer lifting fork is semi-circular, and N lifting forks are evenly arranged on the outer periphery of the disc structure.

[0044] With the above setup, as many flat plates as possible can be stored and processed within a unit area, making the best use of space resources. It also provides convenience for the flat plate holder to rotate with the chassis in the subsequent stacked flat plate material dispensing equipment.

[0045] (2) In this utility model, the function of the separation positioning mechanism is to control the distance between adjacent plate holders in the extended state in the stacked plate holding device, and the hinge mechanism of the same length ensures that the distance between the plate holders is equal during the lifting and lowering process; and control that each plate holder will not rotate along the central axis in the extended state, but that each plate holder rotates synchronously.

[0046] With the above settings, the dispensing needles in the stacked plate material dispensing equipment can be aligned with each plate according to the preset program, while ensuring the distance between the plate holder supports, so that the insertion of stacked plates will not result in misalignment.

[0047] (3) In this utility model, the two arms of the winch mechanism are plate-shaped, which can save storage space as much as possible.

[0048] (4) In this utility model, the flat dish holder also includes: a holder spacing adjustment mechanism, which is set in the central part or the segmented part, parallel to the central axis of the disc-shaped structure, and the height of the holder spacing adjustment mechanism is adjustable.

[0049] With the above settings, if the distance between adjacent plate holders in the stacked plate lifting device is too low, the distance between adjacent plate holders can be increased by adjusting the height of the holder spacing adjustment mechanism, making it more convenient to use.

[0050] (5) In this utility model, the stacked flat dish lifting device includes: M-layer flat dish holders stacked longitudinally, which are set on the base plate, and the flat dish holder is the front flat dish holder; wherein, when each separation and positioning mechanism is in the retracted state, the M-layer flat dish holder is retracted downwards, and the stacked flat dishes of the M layers can be inserted into a certain column of lifting forks of the longitudinally stacked flat dish holder; when each separation and positioning mechanism is in the extended state, the M-layer flat dish holder is lifted upwards, and the lifting part of the m-th flat dish holder lifts the lid of the m-th flat dish and the bottom of the m+1-th flat dish above it upwards, m=1,2,……,M-1.

[0051] With the above-described design, this invention enables the three-dimensional distribution of multiple stacks of petri dishes, significantly saving space. Furthermore, the separation and positioning mechanism allows for the simultaneous automatic opening and closing of large batches of petri dishes, greatly facilitating the work of microbiology laboratories.

[0052] (6) In this utility model, the second end of the lifting wire rope is connected to the center of the top plate bracket through a universal rotating ring.

[0053] The above settings ensure that the steel cable does not rotate as the flat plate bracket rotates with the chassis, thus counteracting the rotational torque.

[0054] (7) The three-dimensional distribution of plates in the stacked plate material dispensing equipment occupies less space and can be placed in equipment such as ultra-clean workbench to realize automatic quantitative filling of small batches of culture medium, which is particularly suitable for customized small batch production.

[0055] In addition, by coordinating the lifting mechanism, rotating mechanism, and needle displacement mechanism, the automated and intelligent packaging of small batches of materials has been achieved, reducing the workload of staff and saving time.

[0056] (8) With the existing petri dish dispensing instrument, the lid is closed immediately after each petri dish is dispensed. The moisture and water vapor in the culture medium cannot be dried quickly, and water mist will form on the inside of the lid, which will affect the normal experiment.

[0057] With the above settings, after the culture medium materials are dispensed, the lids can be closed only after the culture medium has dried, which successfully solves the problem of sterile and properly placed plate lids and ensures the normal progress of the experiment.

[0058] In summary, the stacked petri dish material dispensing equipment of this invention can automatically dispense materials into petri dishes, dispense them into the same stack, and remove them from the same stack, greatly simplifying experimental operations. Attached Figure Description

[0068] The purpose of this utility model is to provide a flat plate tray, a stacked flat plate lifting device, and a stacked flat plate material dispensing equipment with high space utilization, high usage flexibility, and high degree of automation.

[0069] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and with reference to the accompanying drawings.

[0070] This utility model first provides a cover structure bracket; then, based on the specific implementation of the cover structure - a flat plate bracket, it provides a stacked flat plate lifting device; finally, based on the stacked flat plate lifting device, it provides a device and method for dispensing stacked flat plate materials, which will be described in turn.

Figure 6A and Figure 6B They are respectively Figure 4 The image shows the left and right views of the stacked flat-plate material dispensing equipment in its extended state.

[0072] The first aspect of this utility model provides a flat dish holder. Please refer to... Figure 1A , Figure 1B , Figure 2A , Figure 2B , Figure 4 In this embodiment of the utility model, the flat dish holder 10 has an overall disc-shaped structure with a certain thickness, including:

[0073] Central section 11 is located in the middle of the disc-shaped structure;

[0074] Six lifting forks 12 are distributed around the periphery of the disc-shaped structure, and adjacent lifting forks are separated from each other by partitions 13;

[0075] Three separate positioning mechanisms, which can extend or retract along a direction parallel to the central axis of the disc-shaped structure, wherein:

[0076] When the separation and positioning mechanism is in the retracted state, the lid of the plate closes onto the bottom of the plate;

[0077] When the separation positioning mechanism is in the extended state, the lifting part raises the lid of the dish upwards, separating it from the bottom of the dish;

[0078] The lifting fork opening is provided with a guide step 16, which divides the lifting fork opening into two layers; the upper lifting part 16A matches the shape of the plate lid A1; the lower fork inlet 16B matches the shape of the plate bottom A2.

[0079] The following is a detailed description of each component of the flat dish holder in this embodiment.

[0080] like Figure 1A As shown, in this embodiment, the flat dish holder 10 has an overall disc structure, with the outer lifting forks being semi-circular in shape. The six lifting forks are evenly arranged around the periphery of the disc structure. Through this design, the present invention can accommodate and process as many flat dishes as possible within a unit area, maximizing the use of space resources. It also facilitates the rotation of the flat dish holder with the base in subsequent stacked flat dish material dispensing equipment. However, the present invention is not limited to this.

[0081] In other embodiments of this utility model, the flat dish holder can also be elliptical or a regular U-shaped structure, where U ≥ 3, but its space utilization and rotation convenience are not as good as in this embodiment. Similarly, the number of lifting forks around the disc-shaped structure can be adjusted according to the size of the disc-shaped structure and the flat dish. Preferably, N and U are selected from one of the following values: 4, 5, 6, 7, 8, 9, 10. These variations are also within the protection scope of this utility model.

[0082] In other embodiments of this utility model, the lifting fork can also be a semi-circular rectangular shape extending outward along the tangent, as long as it does not affect the insertion of the flat dish.

[0083] Figure 1B This is an enlarged view of the hinge mechanism in the flat dish holder shown in Figure 1. Figure 1A and Figure 1B As shown, in this embodiment, the separation and positioning mechanism is a hinged arm mechanism 14. Three accommodating slots 15 extending radially along the disc-shaped structure are evenly arranged in the partition portion around the central part. A bracket hinge shaft 14A is provided on the wall of one of the accommodating slots near the central axis of the disc-shaped structure. The hinged arm mechanism 14 includes: a lower hinge arm 14B, the upper end of which is hinged to the bracket hinge shaft; and an upper hinge arm 14C, the lower end of which is hinged to the bracket hinge shaft. The rotation ranges of the lower hinge arm 14B and the upper hinge arm 14C around the bracket hinge shaft are located below and above the disc-shaped structure, respectively. Through the above-described arrangement, this invention provides conditions for the retraction and extension of each bracket in the subsequent stacked flat plate lifting device.

[0084] like Figure 1A and Figure 1B As shown, in a bracket assembly composed of multiple flat trays, the lower end of the lower hinge arm of the m-th layer cover structure bracket is hinged to the upper end of the upper hinge arm of the (m-1)-th layer cover structure bracket via an inter-arm hinge shaft; the upper end of the upper hinge arm of the m-th layer cover structure bracket is hinged to the lower end of the lower hinge arm of the (m+1)-th layer cover structure bracket via an inter-arm hinge shaft, where m = 1, 2, ..., M-1.

[0085] As shown in the figure, in this embodiment, the two hinge arms are plate-shaped. This design saves as much storage space as possible, specifically the space occupied by the accommodating slots on the disc-shaped structure.

[0086] As shown in the figure, in this invention, the function of the separation and positioning mechanism is to: ① control the distance between adjacent plate holders in the extended state, ensuring that the spacing between the plate holders remains equal during the lifting and lowering process by using hinge mechanisms of the same length; and ② prevent each plate holder from rotating along the central axis in the extended state, ensuring that each plate holder rotates synchronously. In this invention, by setting this separation and positioning mechanism, the dispensing needles in the stacked plate material dispensing equipment can be aligned with each plate according to a preset program, while ensuring the distance between the plate holder supports, so that the insertion of stacked plates does not result in misalignment.

[0087] As shown in the figure, in this embodiment, the contact between the end of the hinge arm and the opposite receiving groove wall is a point contact. This point contact limits the rotation angle of the hinge, thereby limiting the extension height of each layer of flat dish holders, thus ensuring that the spacing between each layer of flat dish holders is the same.

[0088] like Figure 2B As shown, in the retracted state of the stacked dish holding device, the stacked dishes need to be inserted into a certain column of the device. If the distance between adjacent dish holders is too low, some dishes will get stuck and will not be able to be inserted smoothly into the stack.

[0089] To address the aforementioned issues, this embodiment of the dish holder further includes a dish spacing adjustment mechanism, disposed in the central portion, the segmented portion, or the periphery of the disc-shaped structure, parallel to the central axis of the disc-shaped structure, and the height of this mechanism is adjustable. If the distance between adjacent dish holders in the stacked dish holding device is too low, the distance between adjacent dish holders can be increased by adjusting the height of the dish spacing adjustment mechanism, thus making the device more flexible in use.

[0090] Regarding the separation positioning mechanism, the following aspects need to be explained:

[0091] (1) Control of elongation height

[0092] As mentioned above, in this embodiment, the distance between adjacent flat trays in the extended state is controlled by the point contact between the end of the hinge arm and the wall of the opposite receiving groove, but this utility model is not limited thereto.

[0093] Similarly employing hinge technology, the distance between adjacent flat dish holders can be controlled by adjusting the maximum opening angle of the hinge axis between the arms and the length of the hinge arm. These variations can also achieve the present invention.

[0094] (2) Forms of the separation positioning mechanism

[0095] In this invention, the separation and positioning mechanism serves to achieve equidistant separation of the two layers of flat dish holders. In this embodiment, the separation and positioning mechanism employs a double-hinged arm mechanism, but this invention is not limited to this.

[0096] In other embodiments of this utility model, the same hinge mechanism can be used, but a three-hinged arm mechanism or a four-hinged arm mechanism can be used instead of the double-hinged arm mechanism in this embodiment. If necessary, the position of the bracket hinge shaft needs to be adjusted.

[0097] Besides the hinge mechanism, other separation and positioning mechanisms can also be used, such as: folding hinge mechanism, rope mechanism, chain mechanism, and longitudinal fixed-length bolt mechanism. Taking the longitudinal fixed-length bolt mechanism as an example, the equidistant separation of adjacent bracket mechanisms can be achieved by using a fixed-length bolt to pull the lower layer from the upper layer. At the same time, the rigidity of the bolt can ensure the alignment of the upper and lower flat brackets during rotation.

[0098] (3) The number and location of the separation positioning mechanism

[0099] In this embodiment, three separation and positioning mechanisms are provided on the outer segment, but this utility model is not limited thereto.

[0100] In other embodiments of this invention, the number and position of the separation and positioning mechanisms can be set as needed. If the separation and positioning mechanism is located at the center of the disc-shaped structure, only one separation and positioning mechanism can be provided. If the separation and positioning mechanism is not located at the central axis of the disc-shaped structure, it is preferable to evenly arrange more than three separation and positioning mechanisms on the periphery of the disc-shaped structure to ensure the stability of the plane on which each plate holder is located. In this case, the separation and positioning mechanism can be located at the isolation part or at the central part, as long as the size allows.

[0101] (4) Presence or absence of a separation positioning mechanism

[0102] As mentioned earlier, the separation and positioning mechanism is mainly designed to facilitate the control of the spacing and rotation of the dish holders within the stacked dish holding device. If the dish is not intended for use within the stacked dish holding device, this separation and positioning mechanism can be omitted.

[0103] Those skilled in the art should understand that the above-described modifications can also achieve the present invention and are also within the protection scope of the present invention.

[0104] (5) Applicable to any double-layer cover structure

[0105] Although the above description uses a flat dish holder as an example, this invention can also be applied to other types of double-layered lid structures. As long as the lid is larger in lateral extension than the lower shell, the lifting part can be matched with the shape and / or size of the lid; the fork inlet can be matched with the shape and / or size of the lower shell, thereby enabling the lid to be raised and lowered, and thus allowing the lower shell to be opened and closed. Similar modifications can also achieve this invention, and are also within the scope of protection of this invention.

[0106] In addition to the field of microbial detection, this invention can also be applied in the fields of food and pharmaceutical production, and is also within the scope of protection of this invention.

[0107] This concludes the introduction of the cover-and-fit structure bracket of this utility model.

[0108] Based on the flat dish holder of the above embodiments, the second aspect of this utility model provides a stacked flat dish lifting device. Please refer to... Figure 2A , Figure 2B , Figure 3A , Figure 3B The stacked flat dish lifting device of this utility model includes:

[0109] Chassis 20;

[0110] M-layer flat dish holders 10 are stacked vertically on the base plate, where M≥2, and the flat dish holder is the one in front of the base plate.

[0111] When each separation and positioning mechanism is in the retracted state, the M-layer flat dish holder retracts downwards, and the M-layer stacked flat dishes can be inserted into a certain column of the lifting fork of the longitudinally stacked flat dish holder; when each separation and positioning mechanism is in the extended state, the M-layer flat dish holder is lifted upwards, and the lifting part of the m-th flat dish holder lifts the lid of the m-th flat dish and the bottom of the (m+1)-th flat dish above it upwards, m=1,2,……,M-1.

[0112] This invention, through the aforementioned design, enables the three-dimensional distribution of multiple stacks of petri dishes, significantly saving space. Furthermore, the separation and positioning mechanism allows for the simultaneous automatic opening and closing of large batches of petri dishes, greatly facilitating microbiological experiments.

[0113] In this embodiment, the separation and positioning mechanism is a hinged arm mechanism; S receiving slots extending radially along the disc-shaped structure are evenly arranged in the segmented part around the central part; a bracket hinge shaft is provided in the receiving slot on the side close to or far from the central axis of the disc-shaped structure, and the separation and positioning mechanism is a hinged arm mechanism; the hinged arm mechanism includes: a lower hinge arm, the upper end of which is hinged to the bracket hinge shaft; and an upper hinge arm, the lower end of which is hinged to the bracket hinge shaft; the rotation range of the lower hinge arm and the upper hinge arm around the bracket hinge shaft is located below and above the disc-shaped structure, respectively.

[0114] Regarding the hinge mechanism of the stacked flat plate lifting device, the following aspects need to be specifically explained:

[0115] (1) Hinged arm mechanism between two adjacent flat trays

[0116] like Figure 1A As shown, two adjacent dish holders are connected by three sets of hinged arm mechanisms. For one set of hinged arm mechanisms, the upper end of the upper hinge arm of the lower dish holder is hinged to the lower end of the lower hinge arm of the upper dish holder.

[0117] Specifically, the lower end of the lower hinge arm of the m-th layer plate holder is hinged to the upper end of the upper hinge arm of the (m-1)-th layer plate holder; the upper end of the upper hinge arm of the m-th layer plate holder is hinged to the lower end of the lower hinge arm of the (m+1)-th layer plate holder, where m = 1, 2, ..., M-1.

[0119] Among them, the lower end of the lower hinge arm of the lowest flat tray bracket is hinged to the corresponding hinge shaft on the chassis; the upper end of the upper hinge arm is hinged to the lower end of the hinge arm of the next lower flat tray bracket.

[0120] For details regarding the flat plate support in the stacked flat plate lifting device of this embodiment, please refer to the relevant descriptions of the previous embodiments, which will not be repeated here.

[0121] It should be noted that although this embodiment uses a stacked flat dish lifting device as an example, this utility model does not use it as an example. In other embodiments of this utility model, a double-layered lid lifting structure that meets specific conditions is also applicable. This utility model can also realize the lifting and lowering of lids of multiple lid structures, thereby realizing the opening and closing of the lower shell. Similar modifications can also realize this utility model, and are also within the protection scope of this utility model.

[0122] This concludes the introduction of the stacked cover structure lifting device of this utility model.

[0123] Based on the stacked flat plate lifting device of the above embodiments, the third aspect of this utility model provides a stacked flat plate material dispensing device. Please refer to... Figure 4 , Figure 5A , Figure 5B , Figure 6A , Figure 6B The stacked flat-plate material dispensing equipment in this embodiment includes:

[0124] Frame 30;

[0125] The base of the stacked flat dish lifting device in the above embodiment is fixed on the frame;

[0126] The lifting mechanism 40 controls the M-layer flat dish holder to retract downwards or lift upwards.

[0127] The rotating mechanism 50 is located inside or below the chassis, and drives the chassis to rotate, thereby causing the longitudinally stacked M-layer flat dish holders to rotate.

[0128] The needle displacement mechanism 60 drives the tip of the dispensing needle 71 to move between plates in the stacked plate lifting device in an extended state.

[0129] A material supply mechanism is connected to the dispensing needle 71;

[0130] The control mechanism is connected to the lifting mechanism, rotating mechanism, and needle displacement mechanism via signals.

[0131] The following provides a detailed description of each component of the stacked flat-plate material dispensing equipment in this embodiment.

[0132] Regarding the stacked flat plate lifting device, please refer to the description of the prior embodiment, which will not be repeated here.

[0133] In this embodiment, the material supply mechanism is a peristaltic pump 73, which drives the material flow along the dispensing pipeline 72 to the dispensing needle 71, thereby achieving precise quantitative dispensing of the material. However, this invention is not limited to this. In other embodiments of this invention, other types of material supply mechanisms may also be used.

[0134] In this embodiment, the frame is a square frame with mounting plates at the bottom and top to support the various mechanisms. The rotating mechanism 50, the lower end of the guide rail in the needle displacement mechanism, the peristaltic pump 73, etc., are all mounted on the bottom mounting plate. The pulley fixing seat of the lifting mechanism, the lifting motor fixing seat, the upper end of the guide rail in the needle displacement mechanism, etc., are all mounted on the top mounting plate.

[0135] In this embodiment, the rotating mechanism 50 is located at the bottom of the chassis. It drives the chassis to rotate and in turn drives the longitudinally stacked M-layer flat dish holders to rotate, so that the flat dishes are rotated to the dispensing station.

[0136] In this embodiment, the lifting mechanism 40 is used to drive the M-layer plate holder to rise, so that the plate placed therein is separated. Figure 7A and Figure 7B They are respectively Figure 1A The diagram shows a perspective view and a front view of the lifting mechanism in the stacked flat-plate material dispensing equipment. Please refer to the following: Figure 7A , Figure 7B In this embodiment, the lifting mechanism 40 includes:

[0137] The reversing pulley 41 is installed on the top of the frame above the stacked flat plate lifting device via the pulley fixing seat 42, so that the steel wire rope changes from the horizontal direction of the self-winding wheel to the vertical direction of pulling the uppermost flat plate tray.

[0138] The lifting motor 43 is mounted on the top of the frame via the lifting motor mounting base 44. Its torque output end is connected to the winding wheel 45, which drives the winding wheel to rotate and controls the length of the wire rope.

[0139] The lifting cable 46 is a steel wire rope, with its first end fixed to the winding wheel 45 and its second end passing through the reversing pulley 41 and connected to the center of the top-level flat plate bracket.

[0140] In this embodiment, the second end of the steel wire rope is connected to the center of the top-level flat dish bracket via a universal rotating eyelet 47. In this invention, the connection between the steel wire rope and the flat dish bracket via the universal rotating eyelet ensures that the steel wire rope does not rotate during the rotation of the flat dish bracket with the chassis, thus counteracting the rotational torque.

[0141] The needle displacement mechanism 60 is used to move the dispensing needle in the vertical direction so that it reaches each dispensing station, that is, a position slightly above the bottom of the plate to be dispensed. Figure 8A and Figure 8B They are respectively Figure 1A The diagram shows a perspective view and a front view of the needle displacement mechanism in the stacked flat-plate material dispensing equipment. Please refer to the following: Figure 8A , Figure 8BIn this embodiment, the needle displacement mechanism 60 includes: a longitudinal displacement mechanism, which adopts one of the following forms: slide rail, lead screw, or gear transmission; and a transverse swing mechanism mounted on the longitudinal displacement mechanism; wherein the dispensing needle is mounted on the transverse swing mechanism.

[0142] Specifically, in this embodiment, the lateral swing mechanism is a servo motor 61, which drives the dispensing needle to swing. The longitudinal displacement mechanism adopts a slide rail form and includes:

[0143] Guide rail 62 is set along a direction parallel to the central axis of the disc-shaped structure and serves as a support for needle lifting and guiding the needle lifting action;

[0144] The upper synchronous pulley 63 and the lower synchronous pulley 64 are respectively located at the top and bottom of the guide rail;

[0145] A timing belt 65 is wound around the upper and lower timing pulleys;

[0146] The needle lifting motor 66 has its torque output shaft connected to the drive side of the lower synchronous pulley via a coupling;

[0147] The guide rail slider 67 can slide up and down on the guide rail, connect the timing belt, and fix the servo motor.

[0148] Among them, the needle lifting motor 66 outputs torque to drive the lower synchronous pulley 64 to rotate, the lower synchronous pulley 64 drives the synchronous belt 65 to move, the synchronous belt 65 drives the guide rail slider 67 to move up and down, thereby driving the dispensing needle 71 to move up and down.

[0149] It should be noted that, in addition to the above-described implementation methods, the lifting mechanism and needle lifting mechanism in this utility model can also employ lead screws or gears for transmission, achieving the same function. Those skilled in the art should understand the corresponding implementation methods, which will not be elaborated upon here.

[0150] As can be seen from the above description, the platens in the stacked plate material dispensing equipment of this embodiment are distributed three-dimensionally, the equipment occupies a small space, and can be placed in equipment such as a clean bench to realize automatic quantitative filling of small batches of culture medium, which is particularly suitable for customized small-batch production.

[0151] Based on the stacked flat plate material dispensing equipment of the above embodiments, the third aspect of this utility model provides a stacked flat plate material dispensing method.

[0152] In this embodiment, in the initial state, stacked plates are inserted into the lifting forks of the plate holder assembly in the retracted state. Specifically, when the holder assembly is in the compressed state, a person manually places ten plates in a row onto the plate holder simultaneously, one plate per layer of plate holder. In this way, multiple rows of plates can be placed on the plate holder.

[0153] The material dispensing method in this embodiment is executed by the control mechanism in the stacked flat-plate material dispensing equipment, including:

[0154] Step A: Control the lifting mechanism to rise, which will cause the separation and positioning mechanisms in the stacked plate support device to enter the extended state. The lifting part of each plate support will lift the plate lid of the plate and the bottom of the plate above.

[0155] Specifically, the lifting motor 43 of the lifting mechanism operates, winding the steel wire rope 46. The steel wire rope 46 retracts, driving the uppermost flat dish holder to separate upwards. Due to the hinge mechanism, the upper flat dish holder moves vertically upwards, driving the lower flat dish holder to also move vertically upwards. After each layer of holders completes separation, the same hinge length ensures that the spacing between each layer of flat dish holders is equal. During the upward separation process of the M-layer flat dish holders, the flat dish holders lift the flat dishes simultaneously, with the lifting target being the dish lids. The bottom of the upper layer of dish is placed on the lid of the lower layer, separating the dish bottom and the dish lid, leaving space for material dispensing.

[0156] Step B: Control the needle displacement mechanism to move the dispensing needle above the plate to be dispensed and dispense the material until the dispensing of the current plate is completed.

[0157] Step B further includes: sub-step B1, controlling the lateral swing mechanism to swing the dispensing needle to a position away from the stacked plate support device; sub-step B2, controlling the longitudinal displacement mechanism to move the lateral swing mechanism and the dispensing needle to the height of the plate to be dispensed; sub-step B3, controlling the lateral swing mechanism to swing the dispensing needle above the plate to be dispensed for dispensing; sub-step B4, repeating sub-steps B1 to B3 until the material dispensing of the current column of plates is completed.

[0158] Specifically, after the M-layer plate holder rises to its highest point and each plate is completely separated, the needle lifting motor 66 of the needle displacement mechanism operates, driving the upper and lower synchronous pulleys and synchronous belt 65 to move, thereby causing the guide rail slider 67 to rise and fall. The guide rail slider is guided by the guide rail 62 to ensure vertical movement. At the same time, the servo motor 61 and the dispensing needle 71 also move synchronously. When the needle rises and falls to the dispensing height, the servo motor 61 rotates and swings, moving the dispensing needle 71 to the inside of the plate directly above the plate to be dispensed. The peristaltic pump 72 operates, pumping the material into the plate through the dispensing pipe 73. After dispensing is completed, the servo motor rotates and swings in the opposite direction, moving the dispensing needle 71 to the outside of the plate to prevent the needle from touching or interfering with other components during the lifting and lowering process.

[0159] Step C: The rotating mechanism drives the chassis to rotate, and the rotation of the M-layer plate holder drives the next row of plates to the dispensing station.

[0160] After the current batch of plates is filled, the rotating mechanism drives the chassis to rotate and the M-layer plate holder to move. Due to the three sets of hinge mechanisms, each layer of plate holder and plate rotates synchronously, moving the unfilled plates to the filling station. During the rotation, the relative action of the universal rotating lifting ring 47 prevents the wire rope from twisting radially.

[0161] Step D: Repeat steps B and C until all petri dishes are dispensed.

[0162] Step E: Maintain the lids and bottoms of each dish in the stacked dish material dispensing equipment in a separate state;

[0163] Step F: After manual triggering or completion of the timed period, control the lifting mechanism to descend, causing each separation and positioning mechanism in the stacked flat dish lifting device to enter the retraction mode, and the lid and bottom of each flat dish are closed.

[0164] Specifically, the lifting motor 43 of the lifting mechanism operates, the winding wheel 45 runs in the reverse direction, the wire rope 46 extends, the flat dish lifting device lowers each layer of the support, and the dish lid and bottom close concentrically together. Due to the three sets of hinge mechanisms, the angle of each layer of flat dish support remains consistent, thus ensuring that the dish bottom and lid are concentric. After the dish bottom and lid are completely closed, the workers can take out the packaged flat dishes in the neat rows.

[0165] As can be seen, in actual experiments, the material dispensing equipment of this invention can be used to automatically dispense materials into flat plates, dispense them into the whole stack, and remove them from the whole stack, greatly facilitating experimental operations.

[0166] As mentioned earlier, in existing technologies, the caps are closed immediately after each petri dish is dispensed. This prevents the moisture and water vapor in the culture medium from drying quickly, causing condensation to form on the inside of the cap and affecting normal experiments. The structure in the patent allows the cap to be closed only after the culture medium has dried, effectively solving the problem of proper aseptic placement of the cap and addressing the aforementioned issues.
