Description

Technical Field

[0001] The utility model belongs to the technical field of microbial cultivation and relates to a microbial intelligent incubation system. Background Art

[0002] Microbial incubator is a common laboratory equipment, which is mainly used to provide a stable temperature environment to simulate the ideal conditions for microbial growth, thereby promoting the cultivation and reproduction of various microorganisms such as bacteria, yeast, and mold. It can be used for microbial culture experiments in clinical medicine, scientific research, quality control, teaching experiments, and industrial production processes. The demand for incubator volume varies greatly for laboratories or medical institutions of different sizes. Small laboratories may require a compact design due to limited space, while large laboratories may require large-volume incubators to meet batch sample culture.

[0003] For use scenarios such as hospitals, multiple samples are usually processed at the same time, so large-capacity incubators are needed to meet daily inspection needs. Currently, large-volume incubators are mostly integral structures, which are not convenient for transportation, installation, and later mobile maintenance.

[0004] Moreover, the existing incubators fail to reasonably utilize the internal space, resulting in a small loading capacity. For example, a smart microbial incubator disclosed in a Chinese patent [authorization announcement number is CN219886089U] has an internal storage device that adopts a turntable structure, and the loaders are sequentially placed on the circumference of the turntable frame, which has a small loading capacity and low internal space utilization. Utility Model Content

[0005] The utility model aims to solve the above problems in the prior art and proposes a microbial intelligent incubation system which reasonably utilizes the internal space.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The microbial intelligent incubation system comprises an incubator box with an inlet and an outlet, a transfer unit arranged in the incubator box, and a cover switch unit for opening and closing a cover of a loader, wherein the cover switch unit is provided with a detection unit for detecting the growth status of microorganisms in the loader after the cover is opened, the two sides of the incubator box adjacent to the inlet are storage areas, the transfer unit is located between the two storage areas, and each storage area is provided with a plurality of support plates for placing loaders in a row from top to bottom.

[0008] The storage area is arranged with several support plates in rows from top to bottom, which makes it easy to adjust the number and arrangement gaps of the support plates according to demand, and the storage capacity is highly controllable; the two storage areas are arranged relative to each other to maximize the use of space and improve the internal space utilization and storage capacity.

[0009] The transfer unit is set between the two storage areas, so that one transfer unit can pick up and transfer the loaders on both sides, reducing the number and cost of transfer units. The transfer unit transfers the loaders between the support plate, the sample inlet, the sample outlet and the switch cover unit. The reasonable layout makes the movement stroke of the transfer unit short, thereby improving work efficiency.

[0010] In the above-mentioned microbial intelligent incubation system, the incubator is provided with an isolation chamber connected to the incubator, and the switch cover unit and the detection unit are arranged in the isolation chamber; the switch cover unit includes a first linear module arranged in the isolation chamber, a first tray driven by the first linear module, an opening cover module arranged above the first tray for unlocking the lock of the loader, and a closing cover module for closing the cover of the loader, and the opening cover module, the detection unit and the closing cover module are arranged in sequence along the driving direction of the first linear module.

[0011] The sample inlet and the sample outlet are located on the same side of the incubator, and the isolation chamber is located between the sample inlet and the sample outlet. When it is necessary to detect the growth status of the microorganisms in the loader, the transfer unit grabs the loader on the support plate and places the loader on the first tray. The first linear module drives the loader on the first tray to pass through the cover opening station, the detection station and the cover closing station in sequence. When the loader is at the cover opening station, the cover opening module unlocks the lock of the loader, and the upper cover of the loader pops open under the action of its own torsion spring, so that the loader is in an open state. When the loader is at the detection station, the detection unit detects the growth status of the microorganisms. When the loader is at the cover closing station, the cover closing module closes the upper cover of the loader. After the detection is completed, the transfer unit grabs the loader with the closed cover and sends it to the sample outlet.

[0012] In the above-mentioned microbial intelligent incubation system, the cover opening module includes a guide rail vertically arranged on the inner wall of the isolation chamber, a slider sliding on the guide rail, a cover opening pressure plate arranged on the slider, and a first screw motor for driving the cover opening pressure plate to move up and down, and the cover opening pressure plate is provided with a first positioning bead for pressing the loader lock.

[0013] The first positioning bead is a ball plunger with a spring inside. When the lock of the loader is pressed, the ball head of the first positioning bead moves inward, and the spring is compressed, which plays a certain buffering role. When the first positioning bead presses the lock, the lock deviates to the side away from the upper cover, so that the lock is separated from the limit of the upper cover. At this time, the upper cover is opened under the action of the torsion spring. The lock has a certain elasticity. When the first positioning bead is separated from the lock, the lock is reset under the action of its own elastic force.

[0014] The detection unit is an industrial camera and light bar installed in the isolation chamber. The loader at the detection station is located directly below the industrial camera.

[0016] When closing the cover, the loader moves to the cover closing position under the action of the first linear module, and the second screw motor drives the first connecting head and the first connecting shaft to move together when it is extended and retracted, thereby driving the cover closing push rod to rotate, so that the arc surface approaches and squeezes the loader cover, and finally the cover is closed on the loader. After the cover is closed, the lock limits the cover again.

[0061] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0062] like Figure 1 The microbial intelligent incubation system shown includes an incubator 1 with an incubation chamber (i.e., an inner cavity) inside, a heater, an ultraviolet lamp, and a transfer unit 2 are arranged in the incubator chamber, and an inlet and an outlet connected to the incubator chamber are arranged on the front side of the incubator 1, and a switch cover unit for opening and closing the cover of the loader is arranged between the inlet and the outlet, and a detection unit for detecting the growth status of microorganisms in the loader after opening the cover is arranged at the switch cover unit. The left and right sides of the incubator 1 adjacent to the inlet are storage areas, and the transfer unit 2 is located between the two storage areas, and each storage area is arranged in a row from top to bottom with a plurality of support plates 3 for placing loaders.

[0063] The storage area is arranged with a number of support plates 3 in a row from top to bottom, which is convenient for adjusting the number and arrangement gap of the support plates 3 according to needs, and the storage capacity is highly controllable; the two storage areas are arranged relatively to maximize the use of space, improve the internal space utilization and storage capacity.

[0064] The transfer unit 2 is arranged between the two storage areas, so that one transfer unit 2 can pick up and transfer the loaders on both sides, thereby reducing the number and cost of the transfer units 2. The transfer unit 2 transfers the loaders between the support plate 3, the sample inlet, the sample outlet and the switch cover unit. The reasonable layout shortens the movement stroke of the transfer unit 2, thereby improving the work efficiency.

[0065] Specifically, Figure 6 As shown, the transfer unit 2 includes a sixth linear module 51 extending vertically, a seventh linear module 52 slidably arranged on the sixth linear module 51, and an eighth linear module 53 slidably arranged on the seventh linear module 52. The seventh linear module 52 and the eighth linear module 53 extend horizontally, and the seventh linear module 52 and the eighth linear module 53 are vertically arranged. An electric clamp 54 driven by a rotating motor is arranged on the eighth linear module 53, and the electric clamp 54 is used to grab the loader and move between the support plate 3, the sample inlet, the sample outlet and the switch cover unit.

[0066] The sixth linear module 51 drives the seventh linear module 52 to move up and down, the seventh linear module 52 drives the eighth linear module 53 to move horizontally, and the eighth linear module 53 drives the electric clamp 54 to move horizontally along a horizontal movement direction perpendicular to the eighth linear module 53. The electric clamp 54 can rotate under the action of the rotating motor, so as to facilitate the movement and steering of the loader.

[0067] like Figure 1 , Figure 3-5 As shown, the incubator 1 is provided with an isolation chamber 4 connected to the incubator 1, the isolation chamber 4 is located between the sample inlet and the sample outlet, and the switch cover unit and the detection unit are arranged in the isolation chamber 4. Figure 8As shown, two switch cover units and two detection units are arranged in each isolation chamber 4, which are used to detect the growth status of microorganisms in the loader at the same time, which is conducive to improving the detection efficiency. The isolation chamber 4 is a closed cavity, and the side of the isolation chamber 4 away from the incubator 1 is an openable door body, which is convenient for maintaining each unit in the isolation chamber 4.

[0068] like Fig. 9 As shown, the switch cover unit includes a first linear module 5 arranged in the isolation chamber 4, a first tray 6 driven by the first linear module 5, an opening cover module arranged above the first tray 6 for unlocking the lock of the loader, and a closing cover module for closing the cover of the loader. The opening cover module, the detection unit and the closing cover module are arranged in sequence along the driving direction of the first linear module 5.

[0069] When it is necessary to detect the growth status of microorganisms in the loader, the transfer unit 2 grabs the loader on the support plate 3 and places the loader on the first tray 6. The first linear module 5 drives the loader on the first tray 6 to pass through the cover opening station, the detection station and the cover closing station in sequence. Fig. 9 As shown, when the loader is in the cover opening position, the cover opening module unlocks the lock of the loader, and the upper cover of the loader pops open under the action of its own torsion spring, so that the loader is in an open state, as shown in FIG. Fig.10 As shown, when the loader is in the detection position, the detection unit detects the growth status of microorganisms, such as Fig.11 As shown, when the loader is in the cover closing position, the cover closing module closes the upper cover of the loader. After the detection is completed, the transfer unit 2 grabs the loader with the cover closed and sends it to the sample outlet.

[0070] like Figure 9-10 As shown, the cover opening module includes a guide rail 7 vertically arranged on the inner wall of the isolation chamber 4, a slider slidably arranged on the guide rail 7, a cover opening pressure plate 8 arranged on the slider, and a first screw motor 9 for driving the cover opening pressure plate 8 to rise and fall. The cover opening pressure plate 8 is provided with a first positioning bead 10 for pressing the loader lock buckle. The first positioning bead 10 is a ball head plunger with a spring inside. When pressing the loader lock buckle, the ball head of the first positioning bead 10 moves inward, and the spring is compressed, which plays a certain buffering role. When the first positioning bead 10 presses the lock buckle, the lock buckle deviates to the side away from the upper cover, so that the lock buckle is separated from the limit on the upper cover. At this time, the upper cover is opened under the action of the torsion spring. The lock buckle has a certain elasticity. When the first positioning bead 10 is separated from the lock buckle, the lock buckle is reset under the action of its own elastic force.

[0071] like Figure 9-10 As shown, the detection unit is an industrial camera 11 and a light bar for providing lighting arranged in the isolation chamber 4. The loader at the detection station is located directly below the industrial camera 11. There are two light bars and they are respectively located on two opposite sides of the loader at the detection station.

[0072] Specifically, Fig.10 and Fig.11 As shown, the cover closing module includes a cover closing push rod 12 whose upper end is hinged in the isolation chamber 4 and a power structure for driving the cover closing push rod 12 to rotate. The rotation center line of the cover closing push rod 12 is parallel to the rotation center line of the loader upper cover, and the side of the cover closing push rod 12 facing the loader has an arc surface for pressing the upper cover.

[0073] like Fig.10 and Fig.11 As shown, the power structure includes a second screw motor 13, a first connecting head 14 driven by the second screw motor 13 and a first connecting shaft 15 arranged on the first connecting head 14, the extension direction of the first connecting shaft 15 is parallel to the rotation center line of the cover closing push rod 12, and the cover closing push rod 12 is provided with a slot 16 extending along the length direction thereof, and the first connecting shaft 15 is inserted into the slot 16.

[0074] When closing the cover, the loader moves to the cover closing position under the action of the first linear module 5, and the second screw motor 13 drives the first connecting head 14 and the first connecting shaft 15 to move together when it is extended and retracted, thereby driving the cover closing push rod 12 to rotate, so that the arc surface approaches and squeezes the loader cover, and finally the cover is closed on the loader. After the cover is closed, the lock re-limits the cover.

[0075] like Fig.11 As shown, a positioning bead connecting block 17 is fixed to the free end of the cover closing push rod 12, and a second positioning bead 18 is provided on the positioning bead connecting block 17. When the cover closing module closes the cover of the loader, the second positioning bead 18 abuts against the upper cover of the loader to avoid scratches on the loader when closing the cover.

[0076] like Figure 3-6 As shown, a sample inlet isolation chamber 19 is provided outside the sample inlet of the incubator 1. Fig.13 As shown, one side of the sample injection isolation chamber 19 is provided with a first sample injection door connected to the incubator 1, and a first door body 20 for closing the first sample injection door is provided at the first sample injection door. The other side of the sample injection isolation chamber 19 is provided with a second sample injection door arranged opposite to the first sample injection door, and a second door body 21 for closing the second sample injection door is provided at the second sample injection door. A second tray 22 for placing a loader is provided in the sample injection isolation chamber 19, and the length of the second tray 22 is less than the distance between the first sample injection door and the second sample injection door. A second linear module 23 for driving the second tray 22 to extend from the first sample injection door / second sample injection door is provided in the sample injection isolation chamber 19.

[0077] A control interface connected to the electronic system is provided on the top of the sample injection isolation chamber 19 . The control interface is connected to the control module of the second linear module 23 . The control interface includes a data transmission interface and a motion control interface to control the movement of the second linear module 23 .

[0078] Only one of the first door 20 and the second door 21 is allowed to be opened at the same time, that is, when the first door 20 is opened, the second door 21 is closed, when the second door 21 is opened, the first door 20 is closed, or both the first door 20 and the second door 21 are closed. The second linear module 23 drives the second tray 22 to move along the length direction, and the second tray 22 can be extended from the first door 20 / the second door 21 during the movement.

[0079] Since only one door is in the open state at the same time, continuous entry of outside air is prevented, which has little impact on the hatching environment in the incubator 1 .

[0080] When the second linear module 23 drives the second tray 22 to move, the second tray 22 either extends from the first injection door, extends from the second injection door, or is located between the first injection door and the second injection door, and both ends of the second tray 22 do not extend.
