Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0059] As introduced in the background technology, the existing culture dish preparation device involves too many workstations, resulting in a large overall footprint of the device, and is not suitable for application in small scenarios such as laboratories. In addition, the overall degree of automation of the device is low, and each workstation requires staff to participate in coordination. For example, the storage, retrieval and transportation of culture dishes need to be done manually; the quantitative filling of culture medium requires personnel to monitor at all times, etc., which not only increases the work intensity of personnel, but also increases labor costs, which is not conducive to popularization and use. In order to solve the above technical problems, the present invention proposes a culture dish preparation device and a method of use.
[0060] Example 1

[0062] Among them, the shell of the preparation mechanism 1 is a transparent shell, which can facilitate the observation of the production work of the culture dish 14 in the preparation mechanism 1 to deal with the occurrence of emergencies; the shell of the culture mechanism 2 is the shell structure of the existing constant temperature box, and the specific structural form will not be described in detail here.
[0063] like Figure 2 As shown, the production mechanism 1 is composed of a feeding unit 3, a conveying unit 4, a filling unit 5, a weighing unit 6, a cooling unit 7, a grabbing unit 8, a shaking unit 9 and an import and export unit 10.
[0064] One end of the conveying unit 4 extends into the interior of the shell of the preparation mechanism 1 , which is the input end of the conveying unit 4 , and the other end of the conveying unit 4 extends out of the shell of the preparation mechanism 1 , which is the output end of the conveying unit 4 .
[0065] The feeding unit 3 is located on one side of the conveying unit 4, and is mainly used for storing the culture dishes 14 to be filled; the filling unit 5 and the cooling unit 7 are both on the same side of the feeding unit 3, and are arranged in sequence along the length direction of the conveying unit 4, and the cooling unit 7 is adjacent to the input end of the conveying unit 4. The culture dishes 14 stored in the feeding unit 3 can be placed on the conveying unit 4, and the filling unit 5 can inject culture medium into the culture dishes 14 on the conveying unit 4, and finally place them in the cooling unit 7 to cool and solidify the culture medium.
[0066] The weighing unit 6 is arranged at the bottom of the conveying unit 4. When the culture dish 14 moves to the top of the weighing unit 6, the weighing unit 6 can support the culture dish 14 and monitor the weight change of the culture dish 14 during the filling process to ensure the accuracy of the culture medium filling amount.
[0067] The shaking unit 9 is adjacent to the input end of the conveying unit 4 and close to the cooling unit 7. After filling, the culture dish 14 on the conveying unit 4 can be placed on the shaking unit 9 for shaking, so that the bacterial liquid can be evenly mixed into the culture medium.
[0068] The grabbing unit 8 is arranged on the other side of the conveying unit 4 , which is on a different side from the feeding unit 3 , the filling unit 5 , and the cooling unit 7 , and is mainly used for grabbing and transferring the culture dish 14 to coordinate the work of each station.
[0069] like Figure 7As shown, the feeding unit 3 is composed of a first support platform 3.1, a storage cylinder 3.2, a push plate 3.3 and a first motor 3.4. A plurality of legs are fixedly arranged at the bottom of the first support platform 3.1. The storage cylinder 3.2 is fixedly arranged on the top of the first support platform 3.1. The first support platform 3.1 is a hollow structure, and a side of the first support platform 3.1 close to the conveying unit 4 has an opening. The push plate 3.3 is slidably arranged inside the first support platform 3.1.
[0070] A first through hole is provided at the top center of the first support platform 3.1, and the first through hole is coaxially arranged with the storage tube 3.2. The through hole can allow the culture dish 14 in the storage tube 3.2 to enter the first support platform 3.1; the end of the push plate 3.3 close to the conveying unit 4 is arc-shaped, which can push the culture dish 14 in the first support platform 3.1 onto the conveying unit 4.
[0071] The first motor 3.4 is fixedly arranged at the bottom of the first support platform 3.1. The first motor 3.4 is connected to the push rod 3.3. The first motor 3.4 is a telescopic motor and can push the push plate 3.3 to reciprocate.
[0072] A position sensor is also provided on the first support platform 3 . 1 , which can monitor the position of the culture dish 14 on the conveying unit 4 to determine whether there is a culture dish 14 at a position on the conveying unit 4 close to the feeding unit 3 .
[0073] The storage tube 3.2 is a long cylindrical structure, which is vertically fixed on the top of the first support platform 3.1. In this embodiment, the storage tube 3.2 is composed of several long strips. In other embodiments, the storage tube 3.2 can also be made of steel plates as long as the culture dishes 14 can be stacked and stored in sequence in the vertical direction.
[0074] It is understandable that the first motor 3.4 can also be replaced by a cylinder structure. The specific selection can be made according to actual design requirements, and no excessive restrictions are made here.
[0075] like Fig.10 As shown, the structure of the cooling unit 7 is similar to that of the feeding unit 3. The cooling unit 7 is composed of a third support platform 7.1, a cooling cylinder 7.2, a lifting cylinder 7.3 and a push-pull plate 7.4. The third support platform 7.1 is also a hollow structure. The third support platform 7.1 has an opening at one end close to the conveying unit 4. The push-pull plate 7.4 is slidably arranged inside the third support platform 7.1. The cooling cylinder 7.2 is fixedly arranged on the top of the third support platform 7.1. The top of the third support platform 7.1 is also provided with a second through hole allowing the culture dish 14 to pass through. The second through hole is coaxially arranged with the cooling cylinder 7.2.
[0076] A circular groove for placing a culture dish 14 is provided on the push-pull plate 7.4, and a third long through hole is provided on the push-pull plate 7.4 along its moving direction, one end of the third through hole is connected to the bottom of the circular groove, and the lifting rod of the lifting cylinder 7.3 can pass through the bottom of the first support platform 7.1 and the third through hole on the push-pull plate 7.4 in sequence, and the culture dish 14 on the push-pull plate 7.4 can be lifted into the cooling cylinder 7.2, and the lifting work of the lifting cylinder 7.3 does not affect the reciprocating movement of the push-pull plate 7.4.
[0077] It is understandable that the movement of the push-pull plate 7.4 is also driven by a motor or a cylinder, and the details are not repeated here. The cooling unit 7 is also provided with a position sensor to monitor the culture dish 14 at the conveying end of the conveying unit 4.
[0078] like Figure 6 As shown, the conveying unit 4 is composed of a second support platform 4.1, a conveying belt 4.2 and a second motor 4.3, wherein the conveying belt 4.2 is arranged along the length direction of the second support platform 4.1, and the second motor 4.3 is fixedly arranged on the second support platform 4.1. The conveying belt 4.2 is driven by the second motor 4.3 and drives the culture dish 14 placed on the upper part thereof to move along the length direction of the second support platform 4.1, wherein the second motor 4.3 is a three-phase motor and can rotate forward or reverse according to demand.
[0079] The conveying unit 4 is also provided with a baffle 4.4, which is arranged opposite to the feeding unit 3 and on different sides from the feeding unit 3, and is mainly used to block the culture dish 14 to prevent the push plate 3.3 from pushing the culture dish 14 out of the conveying unit 4.
[0080] The filling unit 5 is an existing culture medium filling structure, and the specific structure will not be described in detail here.
[0081] like Figure 8 As shown, the weighing unit 6 is composed of a first tray 6.1, a third support platform 6.2, a weighing rod 6.3 and a weighing base 6.4, wherein the third support platform 6.2 is fixedly arranged at the bottom of the conveying unit 4, and the weighing base 6.4 is vertically slidably arranged on the side of the third support platform 6.2, and the weighing base 6.4 can slide up and down vertically along the third support platform 6.2.
[0082] The first tray 6.1 is located above the weighing base 6.4, and the first tray 6.1 is connected to the weighing base 6.4 through the weighing rod 6.3. A weight sensor is provided in the weighing base 6.4. The weight on the first tray 6.1 can be transmitted to the weight sensor through the weighing rod 6.3 to monitor the weight of the culture dish 14 and ensure the accuracy of the culture medium filling.
[0083] In order to facilitate the placement of the culture dish 14, a groove for placing the culture dish 14 is set on the top of the first tray 6.1 to limit the position of the culture dish 14. The vertical movement of the weighing base 6.4 can drive the first tray 6.1 to extend from the top of the conveying unit 4 or retract to the bottom of the conveying unit 4, avoiding affecting the conveying work of the conveying unit 4.
[0084] It is understandable that a position sensor is also provided on the weighing unit 6 to monitor the position of the culture dish 14 on top thereof to ensure the accuracy of the lifting of the first tray 6.1.
[0085] like Fig. 9 As shown, the shaking unit 9 is composed of a second tray 9.1, a fourth support platform 9.2, a fifth motor 9.3, an adjustment track 9.4, a mounting block 9.5, a first rocking arm 9.6, a second rocking arm 9.7, a first connecting shaft 9.8 and a second connecting shaft 9.9.
[0086] Specifically, the fourth support platform 9.2 is fixedly arranged at a position adjacent to the input end of the conveying unit 4, and the fourth support platform 9.2 is close to the cooling unit 7, the second tray 9.1 is located above the fourth support platform 9.2, and a fifth motor 9.3 is arranged on the fourth support platform 9.2, the fifth motor 9.3 is a swing motor, a first swing arm 9.6 arranged horizontally is fixedly arranged on the output shaft of the fifth motor 9.3, a first connecting shaft 9.8 is vertically fixedly arranged on the top of the first swing arm 9.6, and the top of the first connecting shaft 9.8 is rotatably connected to the bottom of the second tray 9.1;
[0087] A second connecting shaft 9.9 is also fixedly provided at the bottom of the second tray 9.1. The second connecting shaft 9.9 is located at one side of the first connecting shaft 9.8. The second connecting shaft 9.9 is rotatably connected to one end of the second rocking arm 9.7.
[0088] When not swinging, the second swing arm 9.7 is perpendicular to the first swing arm 9.6, one end of the second swing arm 9.7 is hinged to the second connecting shaft 9.9, and the other end is hinged to the mounting block 9.5 on the fourth support platform 9.2.
[0089] An adjustment track 9.4 is provided on the fourth support platform 9.2, and the mounting block 9.5 can slide in the adjustment track 9.4 to adjust and fix its position. The position of the mounting block 9.5 can be adjusted according to the actual swing intensity requirement, thereby adjusting the pulling force of the second swing arm 9.7 on the second connecting shaft 9.9, and finally changing the swing amplitude of the second tray 9.1. There is no need to change the model of the fifth motor 9.3 or change the power output of the fifth motor 9.3, which greatly reduces the difficulty of use.
[0090] When the swinging operation is performed, the fifth motor 9.5 swings back and forth, so that the second tray 9.1 has a tendency to follow the swinging of the fifth motor 9.5. At the same time, the second swing arm 9.7 pulls the second tray 9.1. Finally, driven by the first swing arm 9.6 and pulled by the second swing arm 9.7, the second tray 9.1 can swing back and forth relative to the first connecting shaft 9.8.
[0091] The shaking unit 9 has a simple and compact overall structure, and can change its shaking amplitude according to the concentration of different culture media, so that the bacterial liquid can be evenly distributed in culture media of different concentrations, thereby ensuring the adaptability of the device.
[0092] In order to ensure that the culture dish 14 is firmly placed on the second tray 9.1, a limiting groove matching the shape of the culture dish 14 is provided on the top of the second tray 9.1. The depth of the limiting groove is the same as the thickness of the culture dish 14, which can effectively limit the position of the culture dish 14.
[0093] Specifically, two arc-shaped limiting plates are fixedly provided on the top of the second tray 9 . 1 . The two limiting plates are arranged opposite to each other to form limiting grooves, and the ends of the two limiting plates do not contact each other, so as to facilitate the grasping unit 8 to take and place the culture dish 14 .
[0094] like Figure 4 As shown, the grabbing unit 8 can move along the length direction and the width direction of the conveying unit. The grabbing unit 8 is composed of a first support frame 8.1, a first slide rail 8.2, a second slide rail, a third motor 8.4 and a grabbing hand 8.5.

The second slide rail and the first slide rail 8.2 are perpendicular to each other in the horizontal direction. The grabber 8.5 is slidably arranged on the second slide rail. A slider 8.3 is slidably provided on the second slide rail. The grabber 8.5 is slidably connected to the slider 8.3. A third motor 8.4 is fixed on the first support frame 8.1. The third motor 8.4 can drive the slider 8.3 to move along the second slide rail, thereby driving the grabber 8.5 to move toward or away from the conveying unit 4.
[0096] like Figure 5 As shown, the grabber 8.5 is composed of a grab plate 8.5.1 and a fourth motor 8.5.2, wherein two grab plates 8.5.1 are provided, and the two grab plates 8.5.1 are arranged opposite to each other, and the grab plates 8.5.1 are inverted L-shaped plate structures, and the vertical plates of the grab plates 8.5.1 have an arc, and the inside of the vertical plates is provided with a step-shaped structure for supporting the bottom of the culture dish 14;
[0097] The fourth motor 8.5.2 is connected to the two grab plates 8.5.1 and can control the two grab plates 8.5.1 to move away from or closer to each other to achieve the placement and removal of the culture dish 14. The fourth motor 8.5.2 is slidably arranged on the slider 8.3 of the second slide rail and can slide vertically along the slider 8.3.
[0098] The gripping unit 8 can clamp the culture dish 14 after filling on the conveying unit 4 to the shaking unit 9 for shaking. After shaking, the culture dish 14 can be clamped to the push-pull plate 7.4 of the cooling unit 7 for cooling.
[0099] The first support frame 8.1 is also provided with a cover opening unit, which reduces the occupied area of the cover opening unit and can move with the grasping unit 8 to open the cover of the culture dish 14 at different positions as needed. For example, when the cover of the culture dish 14 at a certain position is not fastened and becomes loose during the transportation process, the cover can be re-fastened by the cover opening unit, thereby ensuring the emergency response capability of the device.
[0100] The lid opening unit is composed of a suction cup, an air pump and a lifting block. The lifting block is slidably set on the slide groove 8.6 of the first support frame 8.1 and is located directly above the weighing unit 6. The lifting block can move vertically along the first support frame 8.1. The suction cup is fixedly set on the lifting block. The suction cup is connected to the air pump through a hose, which can adsorb and lift the dish cover on the culture dish 14.
[0101] like Fig.11 As shown, the import and export unit 10 is composed of a lifting door 10.1 and a telescopic cylinder 10.2. The lifting door 10.1 is slidably arranged on the outer shell wall between the production mechanism 1 and the maintenance mechanism 2, and the telescopic cylinder 10.2 is fixedly arranged on the outer shell wall between the production mechanism 1 and the maintenance mechanism 2 and is located above the lifting door 10.1.
[0102] The telescopic rod of the telescopic cylinder 10.2 is fixedly connected to the lifting door 10.1, and can drive the lifting door 10.1 to move vertically upward to realize the connection and disconnection between the production mechanism 1 and the maintenance mechanism 2.
[0103] The conversion platform 15 is arranged in the production mechanism 1 and is adjacent to the import and export unit 10. It is mainly used for the temporary placement of the culture dish 14. When the culture dish 14 is transferred between the preparation mechanism 1 and the culture mechanism 2, the grabbing unit 8 can clamp the culture dish 14 on the push-pull plate 7.4 and place it on the conversion platform 15 for temporary placement. When the lifting door 10.1 rises and opens, the in-and-out clamping unit 12 in the culture mechanism 2 can clamp the culture dish 14 on the conversion platform 15 into the culture mechanism 2.
[0104] It is understandable that a position sensor is also provided at the import / export unit 10 to monitor the culture dish 14 on the conversion platform 15 .

A groove matching the outer edge of the dish cover is provided on the inner side wall of the protrusion 11.4, and the protrusion 11.4 is mainly used to support the dish cover of the culture dish 14.
[0108] In this embodiment, the sixth motor 11.2 is a stepping motor, which can accurately control the rotation angle of the rotating table 11.1 according to needs to ensure the efficiency of taking the culture dish 14.
[0109] The setting of the culture support 11 allows the culture dish 14 to be placed vertically, greatly reducing the space occupied by the maintenance of the culture dish 14, and the rotating table 11.1 can move the culture dish 14 to be taken into place by rotating, reducing the moving range of the clamping unit 12, making the maintenance mechanism 2 more compact and reducing the space occupied; and adjacent culture dishes 14 do not contact each other, avoiding the influence of maintenance work between the culture dishes 14.
[0110] It should be noted that the culture dish 14 is placed upside down on the culture support 11, otherwise it will fall.
[0111] like Fig.13 As shown, the in-and-out clamping unit 12 is composed of a second support frame 12.1, a third slide rail 12.2, a support seat 12.3, a seventh motor 12.4, a drive module 12.5 and a clamping claw 12.6.

[0112] The third slide rail 12.2 is a sliding screw substructure, which can drive the support seat 12.3 to move in the vertical direction. The support seat 12.3 is provided with a seventh motor 12.4 inside, and a driving module 12.5 is provided on the top of the support seat 12.3. The driving module 12.5 is connected to the seventh motor 12.4. The driving module 12.5 can rotate in a horizontal plane under the drive of the seventh motor 12.4. The driving module 12.5 is connected to the clamping claw 12.6, and can drive the clamping claw 12.6 to perform a clamping action or drive the clamping claw 12.6 to perform a telescopic movement or drive the clamping claw 12.6 to rotate around the axis.
[0113] The shooting unit 13 is fixedly arranged on the conveying unit 4, and the shooting unit 13 is close to the output end of the conveying unit 4. The shooting unit 13 is provided with a shooting structure such as a camera, and is mainly used to shoot and observe the culture dish 14 after the maintenance is completed. There is a space between the bottom of the shooting unit 13 and the conveying unit 4 to allow the culture dish 14 to pass through. After the shooting is completed, the culture dish 14 can be transported to the output end and recovered under the action of the conveying unit 4.
[0114] The shooting unit 13 is also provided with a position sensor, which can monitor the position of the culture dish 14 at the bottom of the shooting unit 13 to ensure the accuracy of shooting.

[0119] The conveyor belt 4.2 on the conveyor unit 4 moves to convey the culture dish 14 to the top of the weighing unit 6. When the position sensor on the weighing unit 6 detects that the culture dish 14 has reached the specified position, the signal is transmitted to the control center, and the control center controls the weighing base 6.4 to rise, and the culture dish 14 is supported by the first tray 6.1.
[0120] When the culture dish 14 is completely placed on the first tray 6.1, the control center controls the cover opening unit to open the dish cover, and controls the filling unit 5 to fill the culture medium. At the same time, during the filling process, the weight of the culture dish 14 on the first tray 6.1 is monitored by the weighing unit 6, and the filling is stopped when the weight reaches the requirement;
[0121] After the filling is completed, the dish cover is buckled again, and the control center controls the weighing base 6.4 to descend, so that the culture dish 14 on the first tray 6.1 falls on the conveying belt 4.2, and the culture dish is conveyed to the conveying end of the conveying unit 2 through the conveying belt 4.2. The grabbing unit 8 grabs the culture dish 14 to the second tray 9.1 of the shaking unit 9, and the fifth motor 9.3 is started, and the second tray 9.1 is driven to swing through the cooperation of the first swing arm 9.6 and the second swing arm 9.7;
[0122] When the culture medium in the culture dish 14 on the second tray 9.1 is shaken evenly, the culture dish 14 is grabbed by the grabbing unit 8 and placed on the push-pull plate 7.4 of the cooling unit 7, and the shaken culture dish 14 is placed in the cooling cylinder 7.2 through the push-pull plate 7.4;
[0123] After the cooling setting time, the push-pull plate 7.4 takes out the culture dish 14 in the cooling cylinder 7.2, and the grab unit 8 grabs the culture dish 14 to the conversion platform 15. When the culture dish 14 is placed on the conversion platform 15, the telescopic cylinder 10.2 moves to lift the lifting door 10.1;
[0124] When the lifting door 10.1 is fully lifted, the support seat 12.3 moves to the same level as the import and export unit 10, and at the same time, the driving module 12.5 drives the clamping claw 12.6 to pass through the import and export unit 10, and uses the clamping claw 12.6 to clamp the culture dish 14 on the conversion platform 15 into the maintenance mechanism 2;
[0125] When the culture dish 14 enters the curing mechanism 2, the support base 12.3 moves vertically and drives the driving module 12.5 to rotate through the seventh motor 12.4, so that the culture dish 14 is placed in the designated placement slot;
[0126] After all the culture dishes 14 are placed on the culture rack 11, the lifting door 10.1 is closed to maintain the culture dishes 14;
[0127] When the culture dish 14 is cured, the in-and-out clamping unit 12 takes out the culture dish 14 in the designated placement slot, and the control center controls the lifting door 10.1 to open, and the in-and-out clamping unit 12 places the cured culture dish 14 on the conversion platform 15, and uses the grabbing unit 8 to grab the culture dish 14 on the conversion platform 15 to the conveying unit 4;
[0128] The second motor 4.3 on the conveying unit 4 is reversed to convey the cured culture dish 14 to the bottom of the shooting unit 13, and the shooting unit 13 shoots and observes the culture dish 14. After the shooting is completed, the conveying unit 4 continues to transport the culture dish 14, so that the photographed culture dish 14 is conveyed from the output end to the outside of the production mechanism 1 and collected, and at the same time, other cured culture dishes 14 are conveyed to the bottom of the shooting unit 13 for shooting, until all the culture dishes 14 on the curing bracket 11 are photographed.
