Description

Technical Field

[0001] The present invention belongs to the technical field of microbial processing, and relates to an automatic microbial sample processing system and a processing method. Background Art

[0002] Clinical microbiology testing is an indispensable aid in the fields of disease diagnosis, rational use of antibiotics, and hospital infection control in medical institutions. Pretreatment of microbial specimens is a crucial step in testing, requiring a large workload and taking a long time. The results of the pretreatment also directly affect the accuracy of all subsequent tests. Currently, the culture medium streaking and inoculation work in microbiology laboratories of domestic medical institutions mainly relies on manual operations. During the inoculation process, staff members are exposed to the risk of biological infection due to close contact with clinical specimens. In addition, manual operations are greatly affected by human factors. The arbitrariness, non-standardization, and errors of the operation often lead to improper specimen streaking and inoculation, resulting in erroneous culture results.

[0003] To this end, a Chinese patent discloses an automatic microbial sample processing system [application publication number CN112725168A], which includes a base, a sample container transfer and opening device, a culture dish opening and transfer device, and a microbial inoculation device; the culture dish opening and transfer device includes a transfer component, a first culture dish placement tower, a second culture dish placement tower, and a slide module. When the slide module is in the initial position, the transfer component separates the bottom and the cover of the culture dish and places the bottom of the culture dish on the slide module; or pushes the bottom of the culture dish to separate from the slide module, and makes the cover of the culture dish cover the bottom of the dish until the culture dish enters the second culture dish placement tower from the feed end of the second culture dish placement tower.

[0004] In the above-mentioned automatic microbial sample processing system, the culture dish lid opening and transfer device does not require an additional lid opening mechanism, so that the movement of the culture dish and the opening of the lid are carried out simultaneously. Since the movement direction of the slide module is perpendicular to the closing direction of the dish lid, when the dish lid is closed on the bottom of the dish, there is no locking structure between the two. Although it is convenient to open the lid, it is very easy to cause the dish lid to fall off when the staff subsequently observe the growth status of the microorganisms, resulting in a poor user experience.

[0005] If a hinged loader is used, that is, a structure in which the upper cover is hinged on the loading base, the operation is complicated when placing the culture dish on the loader, and a complex opening mechanism needs to be set up in the sample processing system. In addition, the upper cover and the loader occupy a large space during the inoculation process, and the upper cover hinged on the loader will affect the movement of the inoculation needle and the stability of the equipment. Summary of the Invention

[0006] The present invention aims to address the above-mentioned problems in the existing technology and proposes a microbial sample automatic processing system with good stability and a microbial sample automatic processing method using the microbial sample automatic processing system.

[0007] The purpose of the present invention can be achieved through the following technical solutions:

[0008] The automatic processing system for microbial samples includes a workbench, a pushing device arranged on the workbench, a loading turntable and a water flow turntable rotatably arranged on the workbench, the loading turntable is provided with at least one dish cover loading position and multiple loader loading positions, the water flow turntable is provided with multiple loader receiving positions and dish cover receiving positions arranged at intervals, the pushing device is used to push the new dish cover located at the dish cover loading position to the dish cover receiving position, and is also used to push the loader located at the loader loading position to the loader receiving position, the workbench is also provided with a cover opening module, a marking module and a cover closing and moving module which are arranged in sequence along the rotation direction of the water flow turntable, the cover opening module is used to remove the old dish cover of the loader located at the loader receiving position, and the cover closing and moving module is used to cover the new dish cover located at the dish cover receiving position onto the inoculated loader, and the covered new dish cover is engaged with the loader.

[0009] The dish cover loading position and the loader loading position are evenly distributed along the circumferential direction of the loading turntable. The loading turntable and the water flow turntable rotate in steps. Every time the loading turntable and the water flow turntable rotate, there is a dish cover loading position / loader loading position and a loader receiving position / dish cover receiving position arranged opposite to each other. The pushing device is arranged above the loading turntable. The pushing direction extends radially along the loading turntable, and the extended line of the pushing direction passes through the center of the water flow turntable. The dish cover loading position is not lower than the dish cover receiving position, and the loader loading position is not lower than the loader receiving position, to ensure that the pushing device will not be blocked when pushing a new dish cover / loader.

[0010] When the loader is in the loading position, an old dish cover is installed on its upper cover. The old dish cover protects the culture medium inside the loader from the ingress of dust and bacteria. The old dish cover is designed to be separate from the loader, that is, the old dish cover is only placed on the loader and is not connected to the loader in any way, making it easier for the subsequent opening module to open it.

[0011] Two circumferentially evenly arranged elastic buckles are provided on the inner side of the loader, and an annular protrusion extending radially outward is provided on the outer ring surface of the new dish cover. When the new dish cover is set, the elastic buckle presses on the annular protrusion, so that the new dish cover is connected to the loader, which can effectively prevent the new dish cover from falling off when subsequent staff observe the growth status of microorganisms.

[0012] The process of transferring the loader and the new dish cover from the loading turntable to the water flow turntable is as follows: the pushing device rotates to the dish cover loading position closest to the water flow turntable and pushes the new dish cover to the dish cover receiving position closest to the loading turntable on the water flow turntable. Then the loading turntable rotates a certain angle, the water flow turntable rotates a certain angle, and the pushing device pushes the loader at the loader loading position to the loader receiving position, and so on and so forth, so that the new dish cover and the loader move alternately to the water flow turntable.

[0013] The cover opening module removes the old dish cover of the loader located at the loader receiving position, and then the marking module dips the microbial sample and inoculates it into the culture medium of the loader after the cover is opened. Then the cover closing module puts the new dish cover located at the dish cover receiving position onto the inoculated loader, and finally the loader with the new dish cover is packed.

[0014] In the above-mentioned automatic microbial sample processing system, the workbench is also provided with a collection basket for collecting old dish covers, and a horizontal inlet is provided on the bottom side of the collection basket. The above-mentioned opening module is also used to send the opened old dish covers into the horizontal inlet. The collection basket is provided with a pushing assembly for pushing the old dish covers entering the collection basket upward. The collection basket is also provided with a receiving structure for receiving the old dish covers pushed upward by the pushing assembly.

[0015] After opening, the old dish lids are fed into the collection basket through the horizontal inlet by the opening module. The push assembly then rises, causing the old dish lids to move upward to the receiving structure, which supports the old dish lids. As the old dish lids continue to enter, the push assembly pushes them upward one by one, eventually filling the entire collection basket from bottom to top.

[0016] Collecting old dish covers together does not take up space and can improve the stability of system operation. Collecting old dish covers in a collection basket also facilitates centralized processing later.

[0017] In the above-mentioned automatic processing system for microbial samples, the receiving structure includes a first stop block rotatably arranged on the collection basket and a second stop block arranged opposite to the first stop block, the first stop block and the second stop block are arranged at the same height, a first gear rod is provided above the first stop block, and the first stop block resting on the first gear rod under the action of gravity is in a supporting state, a second gear rod is provided above the second stop block, and the second stop block resting on the second gear rod under the action of gravity is in a supporting state, the distance between the first stop block in the supporting state and the second stop block in the supporting state is less than the diameter of the old dish cover, the first stop block swung upward is in a yielding state, the second stop block swung upward is in a yielding state, and the distance between the first stop block in the yielding state and the second stop block in the yielding state is greater than the diameter of the old dish cover.

[0018] The old dish cover fed by the pushing assembly is centered between and below the first and second stops. The pushing assembly pushes the old dish cover upward, squeezing the first and second stops, causing them to swing upward. The old dish cover then passes over the first and second stops, which swing downward under their own gravity to return to the supported state. The pushing assembly then descends, and the old dish cover is supported by the first and second stops. This reciprocating action can lift the old dish covers one by one and limit them by the first and second stops.

[0019] In the aforementioned automated microbial sample processing system, there are two first stops, their rotational midlines coaxial, and two second stops, their rotational midlines coaxial. The distance between the two first stops is less than the diameter of the old dish lid, and the distance between the two second stops is less than the diameter of the old dish lid. The old dish lid fed by the push assembly is centered between the two first stops and the two second stops, and is lower than both the first and second stops. The four stops provide support for the old dish lid, improving stability and effectiveness.

[0020] In the above-mentioned automatic processing system for microbial samples, the pushing assembly includes a vertically arranged first screw motor, a first connecting rod connected to the spline shaft of the first screw motor, and a top plate arranged on the first connecting rod. When the first screw motor is working, it can drive the spline shaft and the first connecting rod to move up and down, and the top plate is centered just below the inner cavity of the collection basket.

[0021] The top plate can be round / square or other shapes, and the top surface area of the top plate is not less than 1 / 3 of the end surface area of the old dish cover, which is conducive to stably lifting the old dish cover upward.

[0022] In the above-mentioned automatic microbial sample processing system, there are two collection baskets and they are arranged in sequence along the extension direction of the transverse inlet. Each collection basket is provided with a pushing assembly and a receiving structure. The previous old dish cover that enters through the transverse inlet first can be pushed into the next collection basket by the next old dish cover that enters later.

[0023] The two collection baskets are connected as one. Setting up two collection baskets can increase the collection capacity. The old dish cover that enters first can be pushed into the next collection basket by the old dish cover behind. At this time, the old dish cover is centered in the next collection basket, and the old dish cover behind is centered in the upper collection basket. The pushing component only needs to move once to push the two old dish covers.

[0024] In the above-mentioned automatic processing system for microbial samples, the opening module includes a first support column arranged on a workbench, a first linear module arranged horizontally on the first support column, a first slide slidably arranged on the first linear module and driven by the first linear module, a second screw motor arranged vertically on the first slide and a first connecting plate arranged on the spline shaft of the second screw motor, the extension direction of the first connecting plate is the same as the extension direction of the first linear module and extends along the extension direction of the horizontal inlet, and the lower side of the first connecting plate is provided with a first suction cup connected to the negative pressure source.

[0025] When the first linear module is working, it drives the first slide to move back and forth linearly, thereby driving the second screw motor, the first connecting plate, the first suction cup and other structures arranged thereon to move back and forth along the extension direction of the first linear module; when the second screw motor is working, it drives the spline shaft and the first connecting plate to move up and down, thereby driving the suction cup to move up and down.

[0026] The working principle of the cover opening module is as follows:

[0027] The first linear module drives the first slide, the second screw motor, and the first connecting plate to move linearly, so that the first suction cup moves to just above the loader located at the loader receiving position, and then the second screw motor works to drive the first connecting plate and the first suction cup to descend, and the first suction cup adsorbs the old dish cover, and then the second screw motor works to drive the first connecting plate and the first suction cup to rise, so that the old dish cover rises to a position at the same height as the horizontal entrance, and then the first linear module works to drive the first connecting plate to move linearly, thereby sending the old dish cover into the designated position of the collection basket through the horizontal entrance, the first suction cup releases the adsorption of the old dish cover, and then the first connecting plate is reset under the action of the first linear module, and such reciprocating action can remove the old dish cover of the loader that moves to this work station.

[0028] In the above-mentioned automatic processing system for microbial samples, a first mounting seat is provided on the first slide, the second screw motor is provided on the first mounting seat, a vertically extending guide rail is provided on the first mounting seat, a slider is provided on the guide rail for sliding, a second connecting rod is fixed on the slider, and the lower end of the second connecting rod is connected to the first connecting plate.

[0029] The guide rail, the slider and the second connecting rod can guide the up and down movement of the first connecting plate, thereby improving the stability of the up and down movement of the first connecting plate.

[0030] In the above-mentioned automatic processing system for microbial samples, the cover closing and moving module includes a second support column arranged on the workbench, a second linear module arranged horizontally on the second support column, a second slide slidably arranged on the second linear module and driven by the second linear module, a third linear module arranged vertically on the second slide, a third slide arranged on the third linear module and driven by the third linear module, and a second connecting plate arranged vertically on the third slide, and the lower end of the second connecting plate is provided with a second suction cup connected to the negative pressure source.

[0031] When the second linear module is working, it drives the third linear module to move. When the third linear module is working, it drives the second connecting plate and the second suction cup to move up and down, thereby realizing the grasping and closing of the new dish cover.

[0032] In the above-mentioned automatic processing system for microbial samples, a laterally extending connecting block is fixed to the lower end of the second connecting plate, and the second suction cup is centrally arranged on the lower side of the connecting block. Spring pins are respectively provided at both ends of the connecting block, and the lower end of the spring pin in a free state is higher than the lower surface of the second suction cup.

[0033] When the second suction cup absorbs the new dish cover, the lower end of the spring pin is higher than the lower surface of the second suction cup. At this time, the lower end of the spring pin will not abut on the new suction cup, so the new suction cup can be absorbed and moved; when the new dish cover is moved to just above the loader, the third linear module causes the connecting block to move downward, and the new dish cover is clamped onto the loader through the squeezing of the spring pin. During this process, the second suction cup is disconnected from the negative pressure source.

[0034] In the above-mentioned automatic microbial sample processing system, longitudinally extending mounting holes are provided at both ends of the connection block, and the spring pins are arranged in different mounting holes, with the lower ends of the spring pins extending downward from the lower ends of the mounting holes.

[0035] The upper part of the spring pin is a spring, and the lower part is a pin. The spring is fixedly connected to the pin. There is an annular step in the mounting hole, which is used to limit the pin downward to prevent the pin from falling out of the mounting hole. A limit plug is provided at the upper end of the mounting hole, and the upper end of the spring acts on the limit plug. Under the action of the spring force, the rod head of the pin rests on the annular step. When the spring pin is subjected to an upward force, the pin can be retracted upward into the mounting hole.

[0036] In the above-mentioned automatic processing system for microbial samples, a downward-extending temporary storage box is provided on the workbench, and a laterally extending fourth linear module is provided below the temporary storage box. A fourth slide driven by the fourth linear module is slidably provided on the fourth linear module, and a hollow receiving tray for receiving the loader is provided on the fourth slide. A printer for printing information on the lower side of the loader is also provided below the temporary storage box, and the fourth linear module drives the hollow receiving tray to move between directly below the temporary storage box and above the printer.

[0037] When the cover closing and moving module puts the new dish cover on the loader, the second suction cup sucks the new dish cover. When the second suction cup moves horizontally, it will drive the loader to move horizontally together. When the loader moves to the top of the temporary storage box, the second connecting plate moves downward, and the loader sucked by the second suction cup enters through the entrance of the temporary storage box. When it drops to a certain position, the second suction cup releases the adsorption of the new dish cover of the loader. At this time, the loader is placed on the hollow receiving plate, and then the third linear module drives the second connecting plate to retract and reset; the fourth linear module located below drives the hollow receiving plate to move horizontally, and transports the loader to the top of the printer. The printer prints the barcode / label information on the lower surface of the loader, and then it is packed through the packing module located below the temporary storage box. The packing module adopts the existing structure.

[0038] In the aforementioned automated microbial sample processing system, the marking module includes a first-zone marking module, a second-zone marking module, and a dipping and capping module. The dipping and capping module is used to open the sample cup lid, while the first-zone marking module and the second-zone marking module are used to move the inoculation needle between the inoculation needle holder, the sample cup, and the loader, respectively. These first-zone marking module, the second-zone marking module, and the dipping and capping module utilize existing structures.

[0039] Compared with existing technologies, this microbial sample automatic processing system has the following advantages:

[0040] The old dish cover and the loader are designed to be separated, which makes it convenient for the subsequent opening module to open the cover. The old dish cover can protect the culture medium in the loader to prevent the entry of dust / bacteria, etc., and avoid contamination of the culture medium; the discarded old dish covers are collected in a centralized manner through the collection basket, which does not take up space, can improve the stability of system operation, and is also convenient for subsequent centralized processing; the new dish cover is snapped into the loader, which can effectively prevent the new dish cover from falling off when subsequent staff observe the growth status of microorganisms; the structural layout is reasonable, there will be no collision between the modules, and the working process is stable and reliable.

[0054] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0055] like Figure 1-3The illustrated automated microbial sample processing system comprises a workbench 1, a pushing device 2 mounted on the workbench 1, a loading turntable 3 and a water flow turntable 4 rotatably mounted on the workbench 1. The loading turntable 3 has a hollowed-out center, and the pushing device 2 is positioned within the hollowed-out center of the loading turntable 3. The pushing device 2 pushes along the radial direction of the loading turntable 3. The pushing device 2 is used to push a new dish cap 10 located at the dish cap loading position 5 to the dish cap receiving position 8, and is also used to push a loader 47 located at the loader loading position 6 to the loader receiving position 7.

[0056] In this embodiment, the pushing device 2 is a linear module, and a slide that is slidably arranged with the linear module and driven by the linear module is fixed on the workbench 1. When the linear module is working, the slide is fixed and the linear module moves radially along the loading turntable 3.

[0057] like Figure 4 As shown, two dish cover loading positions 5 and six loader loading positions 6 are provided on the loading turntable 3 . The two dish cover loading positions 5 are arranged opposite to each other. The eight loading positions formed by the two dish cover loading positions 5 and the six loader loading positions 6 are evenly distributed along the circumference of the loading turntable 3 .

[0058] In this embodiment, the dish cap loading position 5 is a first loading slot provided on the upper portion of the loading turntable 3 for cooperating with new dish caps 10. A dish cap placement basket 45 is provided on the loading turntable 3, located directly above the first loading slot. New dish caps 10 are stacked in a single row from top to bottom in the dish cap placement basket 45. A first exit is provided on the lower, outer side of the dish cap placement basket 45. Only one new dish cap 10 is ejected from the first exit at a time by the pusher 2. The loader loading position 6 is a second loading slot provided on the upper portion of the loading turntable 3 for cooperating with a loader 47. A loader placement basket 46 is provided on the loading turntable 3, located directly above the second loading slot. Loaders 47 are stacked in a single row from top to bottom in the loader placement basket 46. A second exit is provided on the lower, outer side of the loader placement basket 46. Only one loader 47 is ejected from the second exit at a time by the pusher 2.

[0059] The loading turntable 3 is rotatably arranged on the workbench 1. A driving wheel driven by a stepper motor / servo motor is provided below the loading turntable 3. A driven wheel is coaxially provided below the loading turntable 3. The driving wheel and the driven wheel are connected by a belt drive. When the stepper motor / servo motor is working, the driving wheel is driven to rotate, and the driving wheel then drives the driven wheel to rotate, thereby driving the loading turntable 3 to rotate a specified angle.

[0060] like Figure 4As shown, the water flow turntable 4 is provided with four loader receiving positions 7 and four dish lid receiving positions 8. The four loader receiving positions 7 and the four dish lid receiving positions 8 are arranged in an intersecting manner, and the eight receiving positions consisting of the four loader receiving positions 7 and the four dish lid receiving positions 8 are evenly distributed along the circumference of the water flow turntable 4. In order to effectively receive the loader 47 and the new dish lid 10, the loader receiving position 7 is a first receiving groove adapted for the loader 47, and the dish lid receiving position 8 is a second receiving groove adapted for the new dish lid 10.

[0061] The water flow turntable 4 is rotatably set on the workbench 1. A driving wheel driven by a stepper motor / servo motor is located below the water flow turntable 4. A driven wheel is coaxially arranged below the water flow turntable 4. The driving wheel and the driven wheel are connected by a belt drive. When the stepper motor / servo motor is working, it drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate, thereby driving the water flow turntable 4 to rotate. Since the eight receiving positions are evenly distributed around the circumference, the angle of each rotation of the water flow turntable 4 is 8 / 360°=45°.

[0062] Each time the loading turntable 3 and the water flow turntable 4 rotate once, a loading position and a receiving position are arranged opposite to each other, specifically: the dish cover loading position 5 is arranged opposite to the dish cover receiving position 8, or the loader loading position 6 is arranged opposite to the loader receiving position 7. There will be no situation where the dish cover loading position 5 is opposite to the loader receiving position 7, nor will there be a situation where the loader loading position 6 is opposite to the dish cover receiving position 8.

[0063] In order to facilitate the new dish cover 10 / loader 47 to enter the water flow turntable 4 from the loading turntable 3, the dish cover receiving position 8 is not higher than the dish cover loading position 5, and the loader receiving position 7 is not higher than the loader loading position 6.

[0064] Along the rotation direction of the flow turntable 4, the four loader receiving positions 7 are respectively located at the loading station, the first zone marking station, the second zone marking station and the packing station. Only the loader receiving position 7 at the loading station can accept the loader 47 pushed by the pushing device 2.

[0065] like Figure 1-3As shown, the workbench 1 is provided with a cover opening module, a marking module and a cover closing and moving module which are sequentially arranged along the rotation direction of the water flow turntable 4. The cover opening module is located at the loading station and is used to take away the old dish cover 9 of the loader 47 located at the loader receiving position 7. The marking module includes a first-area marking module 41, a second-area marking module 42 and a dipping and capping module 43. The first-area marking module 41 is used to dig the culture medium in the loader 47 located at the first-area marking station. For inoculation and marking, the two-zone marking module 42 is used to inoculate and mark the loader 47 located at the two-zone marking station, the dipping module is used to open the cover of the sample cup, the one-zone marking module 41 and the two-zone marking module 42 are respectively used to move the inoculation needle between the inoculation needle seat 44, the sample cup opened by the dipping cover module 43 and the loader 47, and the one-zone marking module 41, the two-zone marking module 42 and the dipping cover module 43 adopt the existing structure.

[0066] The cover closing and moving module is used to cover the new dish cover 10 located at the dish cover receiving position 8 onto the inoculated loader 47, such as Figure 12 As shown, the installed new dish cover 10 is engaged with the loader 47. The outer periphery of the new dish cover 10 has an annular retaining edge, and the loading seat is provided with two elastic snap-fit structures 48 arranged symmetrically along the center line of the storage cavity. After the new dish cover 10 is installed on the loading seat, the snap-fit structures 48 press against the annular retaining edge to prevent the new dish cover 10 from falling out of the loading seat.

[0067] When loader 47 is in loader loading position 6, it is covered with an old dish cover 9, which protects the culture medium in loader 47 from the ingress of dust and bacteria. The old dish cover 9 is designed to be separate from loader 47, that is, the old dish cover 9 is only placed on loader 47 and is not connected to the loader 47 in any way, making it easier for the subsequent opening module to open the cover.

[0068] like Figure 5 and Figure 6 As shown, the workbench 1 is further provided with a collecting basket 11 for collecting old dish covers 9, a horizontal inlet 12 is provided on the bottom side of the collecting basket 11, and the lid opening module is also used to send the opened old dish covers 9 into the horizontal inlet 12, and the collecting basket 11 is provided with a pushing assembly for pushing the old dish covers 9 entering the collecting basket 11 upward, and the collecting basket 11 is also provided with a receiving structure for receiving the old dish covers 9 pushed upward by the pushing assembly.

[0069] After opening, the old dish lids 9 are fed into the collection basket 11 by the opening module through the transverse inlet 12. Then, the pushing assembly rises to move the old dish lids 9 upward to the receiving structure, which supports the old dish lids 9. As the old dish lids 9 continue to enter, the pushing assembly pushes them up one by one, and eventually the entire collection basket 11 is filled with old dish lids 9 from bottom to top.

[0070] After the old dish lids 9 are collected together, they do not take up space, which can improve the stability of the system operation. The old dish lids 9 are collected together in the collection basket 11, which is also convenient for centralized processing in the later stage.

[0071] like Figure 6 As shown, the receiving structure includes a first stopper 13 rotatably arranged on the collection basket 11 and a second stopper 14 arranged opposite to the first stopper 13. The first stopper 13 and the second stopper 14 are arranged at the same height. A first gear rod 15 is provided above the first stopper 13. Under the action of gravity, the first stopper 13 resting on the first gear rod 15 is in a supporting state. A second gear rod 16 is provided above the second stopper 14. Under the action of gravity, the second stopper 14 resting on the second gear rod 16 is in a supporting state. The distance between the first stopper 13 in the supporting state and the second stopper 14 in the supporting state is less than the diameter of the old dish cover 9. The first stopper 13 swung upward is in a yielding state. The second stopper 14 swung upward is in a yielding state. The distance between the first stopper 13 in the yielding state and the second stopper 14 in the yielding state is greater than the diameter of the old dish cover 9.

[0072] The old dish cover 9 fed in by the pushing assembly is centered between and below the first stopper 13 and the second stopper 14. The pushing assembly pushes the old dish cover 9 upward, during which the old dish cover 9 squeezes the first stopper 13 and the second stopper 14, causing the first stopper 13 and the second stopper 14 to swing upwards respectively. Then, the old dish cover 9 passes over the first stopper 13 and the second stopper 14, which swing downwards to return to the supporting state under the action of their own gravity. Then, the pushing assembly descends, and the old dish cover 9 is supported by the first stopper 13 and the second stopper 14. This reciprocating action can push the old dish covers 9 upwards one by one and limit them by the first stopper 13 and the second stopper 14.

[0073] In order to effectively support the old dish cover 9, as Figure 5 and Figure 6 As shown, there are two first stops 13 with their rotational centerlines coaxial, and two second stops 14 with their rotational centerlines coaxial. The distance between the two first stops 13 is less than the diameter of the old dish cover 9, and the distance between the two second stops 14 is less than the diameter of the old dish cover 9. The old dish cover 9 fed by the push assembly is centered between the two first stops 13 and the two second stops 14, and is lower than the first and second stops 13, 14. The four stops support the old dish cover 9, improving stability and support effect.

[0074] like Figure 5 and Figure 6As shown, the pushing assembly includes a vertically arranged first screw motor 17, a first connecting rod 18 connected to the spline shaft of the first screw motor 17, and a top plate 19 arranged on the first connecting rod 18. When the first screw motor 17 is working, it can drive the spline shaft and the first connecting rod 18 to move up and down, and the top plate 19 is centrally arranged just below the inner cavity of the collection basket 11.

[0075] The top plate 19 can be circular / square or other shapes. In this embodiment, a circular top plate 19 is used. The top surface area of the top plate 19 is not less than 1 / 3 of the end surface area of the old dish cover 9, which is conducive to stably lifting the old dish cover 9 upward.

[0076] like Figure 5 and Figure 6 As shown, there are two collection baskets 11 and they are arranged in sequence along the extension direction of the transverse inlet 12. Each collection basket 11 is equipped with a pushing assembly and a receiving structure. The previous old dish cover 9 that enters through the transverse inlet 12 first can be pushed into the next collection basket 11 by the next old dish cover 9 that enters later. The two collection baskets 11 are connected as one. Providing two collection baskets 11 can increase the collection capacity. The previous old dish cover 9 that enters first can be pushed into the next collection basket 11 by the next old dish cover 9. At this time, the previous old dish cover 9 is centered in the next collection basket 11, and the next old dish cover 9 is centered in the previous collection basket 11. The pushing assembly only needs to be activated once to push both old dish covers 9.

[0077] like Figure 7 As shown, the cover opening module includes a first support column 20 arranged on the workbench 1, a first linear module 21 arranged horizontally on the first support column 20, a first slide 22 slidably arranged on the first linear module 21 and driven by the first linear module 21, a second screw motor 23 vertically arranged on the first slide 22 and a first connecting plate 24 arranged on the spline shaft of the second screw motor 23. The extension direction of the first connecting plate 24 is the same as the extension direction of the first linear module 21 and extends along the extension direction of the horizontal inlet 12. The lower side of the first connecting plate 24 is provided with a first suction cup 25 connected to the negative pressure source.

[0078] When the first linear module 21 is working, it drives the first slide 22 to move back and forth linearly, thereby driving the second screw motor 23, the first connecting plate 24 and the first suction cup 25 and other structures arranged thereon to move back and forth along the extension direction of the first linear module 21; when the second screw motor 23 is working, it drives the spline shaft and the first connecting plate 24 to move up and down, thereby driving the suction cup to move up and down.

[0079] like Figure 7As shown, the first slide 22 is provided with a first mounting seat 26, the second screw motor 23 is provided on the first mounting seat 26, the first mounting seat 26 is provided with a vertically extending guide rail 27, a slider 28 is slidably provided on the guide rail 27, a second connecting rod 29 is fixed to the slider 28, and the lower end of the second connecting rod 29 is connected to the first connecting plate 24. The guide rail 27, the slider 28 and the second connecting rod 29 can guide the up and down movement of the first connecting plate 24, thereby improving the stability of the up and down movement of the first connecting plate 24.

[0080] like Figure 8 As shown, the lid closing and moving module includes a second support column 30 mounted on the workbench 1, a second linear module 31 mounted horizontally on the second support column 30, a second slide mounted on and driven by the second linear module 31, a third linear module 32 mounted vertically on the second slide, a third slide mounted on and driven by the third linear module, and a second connecting plate 33 mounted vertically on the third slide. The lower end of the second connecting plate 33 is provided with a second suction cup 34 connected to a negative pressure source. When the second linear module 31 is in operation, it drives the third linear module to move. When the third linear module is in operation, it drives the second connecting plate 33 and the second suction cup 34 to move up and down, thereby achieving the grasping and closing of the new dish lid 10.

[0081] like Figure 8 and Figure 9 As shown, a laterally extending connecting block 35 is fixed to the lower end of the second connecting plate 33, and a second suction cup 34 is centrally arranged on the lower side of the connecting block 35. Two spring pins 36 are respectively provided at both ends of the connecting block 35, and the lower end of the spring pin 36 in a free state is higher than the lower surface of the second suction cup 34.

[0082] When the second suction cup 34 sucks the new dish cover 10, since the lower end of the spring pin 36 is higher than the lower surface of the second suction cup 34, the lower end of the spring pin 36 will not abut on the new suction cup, so the new suction cup can be sucked and moved; when the new dish cover 10 is moved to just above the loader 47, the third linear module causes the connecting block 35 to move downward, and the new dish cover 10 is clamped onto the loader 47 through the squeezing of the spring pin 36. During this process, the second suction cup 34 is disconnected from the negative pressure source.

[0083] In order to facilitate the installation of the spring pins 36, longitudinally extending mounting holes are provided at both ends of the connecting block 35. The spring pins 36 are arranged in different mounting holes, and the lower ends of the spring pins 36 extend downward from the lower ends of the mounting holes.

[0084] The upper part of the spring pin 36 is a spring, and the lower part is a pin. The spring is fixedly connected to the pin. There is an annular step in the mounting hole, which is used to limit the pin downward to prevent the pin from falling out of the mounting hole. A limit plug is provided at the upper end of the mounting hole, and the upper end of the spring acts on the limit plug. Under the action of the spring force, the rod head of the pin rests on the annular step. When the spring pin 36 is subjected to an upward force, the pin can be retracted upward into the mounting hole.

[0085] like Figure 2 and Figure 10 As shown, the workbench 1 is provided with a temporary storage box 37 arranged opposite to the packing station, and a transversely extending fourth linear module 38 is provided below the temporary storage box 37. A fourth slide driven by the fourth linear module 38 is slidably provided on the fourth linear module 38, and a hollow receiving tray 39 for receiving the loader 47 is provided on the fourth slide. A printer 40 for printing information on the lower side of the loader 47 is also provided below the temporary storage box 37. The fourth linear module 38 drives the hollow receiving tray 39 to move between directly below the temporary storage box 37 and above the printer 40. A packing module (not shown in the figure) is provided below the hollow receiving tray 39, and the packing module adopts the existing structure.

[0086] The working process of the loading turntable 3, the water flow turntable 4 and the pushing device 2 is as follows:

[0087] The loading turntable 3 rotates, moving the lid loading position 5 to a position opposite the loading station. The pushing device 2 pushes a new lid 10 to the lid receiving position 8 located at the loading station. The loading turntable 3 continues to rotate, moving the loader loading position 6 to a position opposite the loading station. Simultaneously, the water flow turntable 4 rotates 45°, moving one of the loader receiving positions 7 to the loading station. The pushing device 2 pushes a loader 47 to the loader receiving position 7 located at the loading station. This reciprocating action pushes new lids 10 and loaders 47 toward the water flow turntable 4 at intervals.

[0088] The working principle of the cover opening module is as follows:

[0089] The first linear module 21 drives the first slide 22, the second screw motor 23, and the first connecting plate 24 to move linearly, so that the first suction cup 25 moves to just above the loader 47 located at the loader receiving position 7. Then the second screw motor 23 works to drive the first connecting plate 24 and the first suction cup 25 to descend, and the first suction cup 25 adsorbs the old dish cover 9. Then the second screw motor 23 works to drive the first connecting plate 24 and the first suction cup 25 to rise, so that the old dish cover 9 rises to a position at the same height as the horizontal entrance 12. Then the first linear module 21 works to drive the first connecting plate 24 to move linearly, thereby sending the old dish cover 9 into the designated position of the collection basket 11 through the horizontal entrance 12. The first suction cup 25 releases the adsorption of the old dish cover 9. Then the first connecting plate 24 is reset under the action of the first linear module 21. Such reciprocating action can adsorb the old dish cover 9 of the loader 47 that moves to the loading station to the collection basket 11, and the old dish cover 9 is collected in a centralized manner through the collection basket 11.

[0090] The loader 47 , after being opened, continues to rotate along with the water flow turntable 4 , and completes the inoculation and marking under the action of the first zone marking module 41 and the second zone marking module 42 .

[0091] When the loading turntable 3 moves to the packing station, the second suction cup 34 has already sucked a new dish cover 10, and under the action of the cover closing moving module, the new dish cover 10 is placed on the loading seat. Then the second suction cup 34 sucks the new dish cover 10. When the second suction cup 34 moves horizontally, it will drive the loader 47 to move horizontally together. When the loader 47 moves to the top of the temporary storage box 37, the second connecting plate 33 moves downward, and the loader 47 sucked by the second suction cup 34 enters through the entrance of the temporary storage box 37. When it descends to a certain position, the second suction cup 34 releases the adsorption of the new dish cover 10 of the loader 47. At this time, the loader 47 is placed on the hollow receiving plate 39, and then the third linear module drives the second connecting plate 33 to retreat and reset; the fourth linear module 38 located below drives the hollow receiving plate 39 to move horizontally, and transports the loader 47 to the top of the printer 40. The printer 40 prints the barcode / label information on the lower surface of the loader 47, and then it is packed through the packing module located below the temporary storage box 37.

[0092] The automatic processing method of microbial samples comprises the following steps:

[0093] Step 1: The loading turntable 3 rotates to move the lid loading position 5 to a position opposite to the loading station, and the pushing device 2 pushes a new lid 10 to the lid receiving position 8 located at the loading station;

[0094] Step 2: The transfer turntable 3 rotates to rotate the loader loading position 6 to a position opposite to the loading station. The flow turntable 4 rotates to rotate one of the loader receiving positions 7 to the loading station. The pushing device 2 pushes a loader 47 to the loader receiving position 7 located at the loading station.

[0095] Step 3: The second screw motor 23 operates to drive the first connecting plate 24 and the first suction cup 25 to move downward. Under the action of negative pressure, the first suction cup 25 sucks the old dish cover 9 located on the loader 47 at the loading station. Then, the second screw motor 23 causes the first connecting plate 24 and the first suction cup 25 to rise, driving the old dish cover 9 to rise together with the horizontal inlet 12 to complete the cover opening action.

[0096] Step 4: The first linear module 21 drives the first slide 22, the second screw motor 23, and the first connecting plate 24 to move linearly, feeding the old dish cover 9 into the collection basket 11 through the horizontal inlet 12. The first suction cup 25 releases the suction of the old dish cover 9, completing the feeding of the old dish cover 9.

[0097] Step 5: The first screw motor 17 works, driving the spline shaft of the first screw motor 17, the first connecting rod 18 and the top plate 19 to rise and fall. The top plate 19 pushes the old dish cover 9 upward, so that the old dish cover 9 passes over the first stopper 13 and the second stopper 14 that are oppositely arranged. The first stopper 13 and the second stopper 14 are first swung upward, and then reset under the action of gravity. The first screw motor 17 drives the top plate 19 to descend, and the old dish cover 9 is supported on the first stopper 13 and the second stopper 14. Then the first screw motor 17 drives the top plate 19 to reset.

[0098] Step 6: The water turntable 4 drives the loader 47 to pass through the first zone marking station and the second zone marking station respectively. During this process, the first zone marking module 41 and the second zone marking module 42 complete the inoculation and marking of the culture medium in the loader 47;

[0099] Step 7: When the new lid 10 rotates to the packing station, the third linear module 33 drives the second connecting plate 33, the connecting block 35 and the second suction cup 34 to descend. The second suction cup 34 uses negative pressure to absorb the new lid 10 at the packing station. Then, the third linear module 33 drives the new lid 10 to ascend.

[0100] Step 8: When the loader 47 moves to the packing station, the third linear mold group 33 drives the new dish cover 10 to descend. During this process, the new dish cover 10 is gradually placed on the loader 47 and the spring pin 36 completes the engagement between the new dish cover 10 and the loader 47.

[0101] Step 9: After the third linear module 33 drives the loader 47 with the new dish cover 10 to rise a certain distance, the second linear module 31 drives the third linear module 32 and the loader 47 sucked by the second suction cup 34 to move horizontally and linearly together until the loader 47 moves to just above the temporary storage box 37. Then, the third linear module 32 lowers the loader 47 and the hollow receiving plate 39 catches the loader 47. The third linear module 32 and the second linear module 31 return to their original position.

[0102] Step 10: The fourth linear module 38 drives the hollow receiving plate 39 to move horizontally, causing the loader 47 to move above the printer 40. The printer 40 rises under the action of the third screw motor and prints information on the lower surface of the loader 47. The hollow receiving plate 39 and the printer 40 are then reset.

[0103] Step 11: The loader 47 is packed by the packing module located below the temporary storage box 37. Repeating steps 1 to 11 can make the microbial sample automatic processing system work continuously.
