Description

Technical Field

[0001] The invention relates to the technical field of microbial cultivation, and in particular to a glass bead coating device. Background Art

[0002] When culturing microorganisms, it is necessary to first apply a diluted solution containing the microorganisms to the culture medium in the culture dish, then add a lysis solution to the culture dish to release the contents of the microbial cells, and then add glass beads to the culture dish. By rolling the glass beads in the culture dish, the microorganisms can be spread to every corner of the culture dish, so that the microorganisms can be cultured into colonies in the culture dish.

[0003] However, the operation of adding lysis solution and glass beads to the culture dish manually can easily cause contamination to the surface of the lysis solution and glass beads, which can easily have a significant impact on the culture effect of the microorganisms, thus placing high demands on the operators. In addition, the efficiency of manual addition is low, which has a significant impact on the culture time of the microorganisms. In addition, during the culture process of the microorganisms, the operator may come into direct contact with the microorganisms, which has a significant impact on the operator's safety.

[0029] In order to make the purpose, technical scheme and advantages of the present invention more obvious, the exemplary embodiments according to the present invention will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments of the present invention, and it should be understood that the present invention is not limited to the exemplary embodiments described herein. Based on the embodiments of the present invention described in the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the present invention.

[0030] In the following description, a large amount of details are provided so that the present invention can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present invention, and the present invention can be implemented without one or more such details. In addition, in order to avoid confusion with the present invention, some technical features well known in the art are not described in detail.

[0031] In order to fully understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other embodiments.

[0032] In one embodiment of the present invention, a glass bead coating device is provided. The glass bead coating device can realize automatic feeding operation, liquid adding operation and bead adding operation, etc., and is used to inoculate the strain by moving the glass beads with the strain on the culture medium during bacterial culture. The trajectory of the glass beads moving on the culture medium can be understood as coating. The following will introduce a glass bead coating device according to an embodiment of the present invention in detail in conjunction with the accompanying drawings.

[0033] like Figures 1 to 5 As shown, the glass bead coating device includes a conveying component 1, a feeding device 2, a liquid adding device and a bead adding device 3. The feeding device 2, the liquid adding device (not shown in the figure) and the bead adding device 3 are sequentially arranged along the conveying direction of the conveying component 1. The feeding device 2 is used to store the culture dish 6 and transport the culture dish 6 to the conveying component 1. The conveying component 1 is used to transport the culture dish 6 to the liquid adding device and the bead adding device 3 in sequence. The liquid adding device is used to add bacterial liquid into the culture dish 6. The bead adding device 3 is used to place glass beads in the culture dish 6. Among them, the loading device 2 includes a first conveying member 21, a dragging component 22 and a receiving component 23. The first conveying member 21 is sequentially provided with a loading position 211 and a waiting position 212 along its conveying direction. The dragging component 22 and the receiving component 23 are respectively arranged on the side of the waiting position 212. A plurality of culture dishes 6 are stacked at the loading position 211 to form a culture dish group. The first conveying member 21 drives the culture dish group to move from the loading position 211 to the waiting position 212. The dragging component 22 is used to drag the culture dish group on the waiting position 212 to the receiving component 23. The receiving component 23 is used to transfer each culture dish 6 in the culture dish group dragged by the dragging component 22 to the conveying component 1 respectively.

[0034] The conveying assembly 1 can be specifically a conveyor belt, under the drive of the conveyor belt, the culture dishes 6 on the loading device 2 can be sequentially transported to the liquid adding device and the bead adding device 3. The first conveying member 21 can also be specifically a conveyor belt, and the conveyor belt is sequentially provided with a loading position 211 and a waiting position 212 along its conveying direction. The operator can stack multiple culture dishes 6 to form a culture dish group and place them on the loading position 211 of the conveyor belt.

[0035] When the culture dish group moves from the loading position 211 to the waiting position 212 driven by the first conveying member 21, at least part of the dragging component 22 can move toward the direction close to the culture dish group and act on the culture dish group, thereby dragging the culture dish group to the receiving component 23, and then the receiving component 23 can be used to disperse the culture dish group and transfer each culture dish 6 to the conveying component 1 in turn.

[0036] In the glass bead coating equipment of the present invention, the first conveying member 21 can convey the culture dish 6 group stacked thereon from the loading position 211 to the waiting position 212, and the dragging component 22 can cooperate with the receiving component 23 to disassemble the culture dish group into multiple culture dishes 6, and convey them to the liquid adding device and the bead adding device 3 in sequence, so as to complete the addition of bacterial liquid and glass beads to the culture dishes 6. In this way, the automatic loading operation, liquid adding operation and bead adding operation are realized, which not only effectively improves the efficiency and effect of glass bead coating, but also avoids direct contact between the operator and the culture dish 6, effectively improving the safety of the operator.

[0037] In some embodiments, Figures 1 to 3 As shown, the pulling component 22 includes a first pulling member 221 and a second pulling member 222, and the first pulling member 221 and the second pulling member 222 are respectively arranged on two opposite sides of the culture dish group of the waiting position 212, and the first pulling member 221 and the second pulling member 222 can move in a direction away from or close to the receiving component 23. The first pulling member 221 and the second pulling member 222 are used to cooperate to drive the culture dish group of the waiting position 212 to move in a direction close to the receiving component 23, so as to drive the culture dish group to move from the waiting position 212 to the receiving component 23.

[0038] The traction assembly 22 may include a first driving member 223 and a second driving member 224 respectively arranged corresponding to the first traction member 221 and the second traction member 222. The first driving member 223 may be connected to the first traction member 221 via a third driving member 225, and the second driving member 224 may be connected to the second traction member 222 via a fourth driving member 226.

[0039] like Figures 1 to 3 As shown, the first driving member 223 can drive the third driving member 225 and the first dragging member 221 to move away from or close to the receiving assembly 23, and the third driving member 225 can drive the first dragging member 221 to move away from or close to the first conveying member 21. Similarly, the second driving member 224 can drive the fourth driving member 226 and the second dragging member 222 to move away from or close to the receiving assembly 23, and the fourth driving member 226 can drive the second dragging member 222 to move away from or close to the first conveying member 21. Among them, the first driving member 223, the second driving member 224, the third driving member 225 and the fourth driving member 226 can be specifically cylinders or other devices that can drive the first dragging member 221 and the second dragging member 222 to move, and the present application does not make specific limitations on this.

[0040] The first dragging member 221 and the second dragging member 222 can be respectively driven by the first driving member 223 and the second driving member 224 to move to the side of the culture dish group on the waiting position 212 away from the receiving component 23, and then the third driving member 225 and the fourth driving member 226 can respectively drive the first dragging member 221 and the second dragging member 222 to move toward the first conveying member 21 to respectively abut against the side walls of the culture dish group. At this time, the first dragging member 221 and the second dragging member 222 can be respectively driven by the first driving member 223 and the second driving member 224 to move toward the receiving component 23 until the culture dish group is dragged onto the receiving component 23.

[0041] In the above embodiment, the position of the culture dish group can be accurately controlled through the cooperation of the first pulling member 221 and the second pulling member 222, ensuring that the culture dish group can be accurately moved to the receiving assembly 23, effectively ensuring the reliability of the feeding device 2. In addition, manual intervention can be reduced, effectively improving the automation level and feeding efficiency of the feeding device 2.

[0042] In some embodiments, Figure 3 As shown, the receiving assembly 23 includes a receiving member 231, and the receiving member 231 includes a plurality of receiving bodies that move toward each other, and the plurality of receiving bodies have a first state in which they are close to each other and a second state in which they are far away from each other. In the first state, the first dragging member 221 and the second dragging member 222 cooperate to drag the culture dish group in the waiting position 212 onto the receiving member 231. In the second state, the receiving member 231 cancels the supporting force on the culture dish group on the receiving member 231, so that the culture dish 6 placed at the bottom of the culture dish group is transferred to the conveying assembly 1 after being subjected to the force.

[0043] like Figure 3 As shown, the receiving member 231 may include a first receiving body 2311 and a second receiving body 2312 that move toward each other. The first receiving body 2311 and the second receiving body 2312 may approach each other to form a first state. In the first state, the first dragging member 221 and the second dragging member 222 cooperate to drag the culture dish group located at the waiting position 212 to the receiving surface formed by the first receiving body 2311 and the second receiving body 2312. The first receiving body 2311 and the second receiving body 2312 may move away from each other to form a second state. In the second state, the first receiving body 2311 and the second receiving body 2312 may cancel the receiving force on the culture dish group, so that each culture dish 6 in the culture dish group can be sequentially transferred from bottom to top to the conveying component 1.

[0044] In the above embodiment, the receiving member 231 can be flexibly switched between the first state and the second state, so that the receiving force can be applied to and removed from the culture dish group, reducing manual intervention and effectively improving the automation level of the loading device 2, as well as the convenience and practicality of use.

[0045] In some embodiments, Figure 3 As shown, the receiving assembly 23 also includes a limit member 232, which is located above the receiving member 231. The limit member 232 includes a plurality of limit bodies that move toward each other, and the plurality of limit bodies have a third state of being close to each other and a fourth state of being far away from each other. In the third state, the limit member 232 is used to limit the second culture dish 6 from bottom to top in the culture dish group on the receiving member 231. In the fourth state, the limit member 232 cancels the force applied to the culture dish group on the receiving member 231. The limit member 232 is at least used to switch from the fourth state to the third state when the receiving member 231 is in the second state.

[0046] like Figure 3 As shown, the limiting member 232 may include a first limiting body 2321 and a second limiting body 2322 moving toward each other, the first limiting body 2321 and the second limiting body 2322 may approach each other and apply a limiting force to the culture dish group to form a third state, and the first limiting body 2321 and the second limiting body 2322 may move away from each other and cancel the limiting force applied to the culture dish group to form a fourth state.

[0047] When the receiving member 231 is in the first state, the first dragging member 221 and the second dragging member 222 can cooperate to drag the culture dish group in the waiting position 212 onto the receiving member 231. At this time, the limiting member 232 can be in the third state to limit the displacement of the second culture dish 6 and the above culture dishes 6 from bottom to top in the culture dish group, and then the receiving member 231 can be switched from the first state to the second state, so that the culture dish 6 located at the bottom of the culture dish group can be transferred to the conveying component 1. After the transfer is completed, the receiving member 231 can be switched from the second state to the first state, and the limiting member 232 can be switched from the third state to the fourth state. At this time, the remaining culture dishes 6 in the culture dish group can fall onto the receiving member 231 under the action of gravity, and the loading device 2 can repeat the above operation to transfer each culture dish 6 in the culture dish group to the conveying component 1 in turn.

[0048] In the above embodiment, the limiting member 232 can be flexibly switched between the third state and the fourth state, and then with the cooperation of the receiving member 231, each culture dish 6 in the culture dish group can be transferred to the conveying component 1 in turn, which effectively improves the convenience and efficiency of loading of the loading device 2 and greatly improves the practicality of the loading device 2.

[0049] In some embodiments, Figure 4As shown, the conveying assembly 1 includes a second conveying member 11, a third conveying member 12 and a fourth conveying member 13 arranged in sequence along a first direction. In the first direction, the third conveying member 12 and the second conveying member 11 have an overlapping first transition section 14, and the fourth conveying member 13 and the third conveying member 12 have an overlapping second transition section 15; wherein the length of the second transition section 15 is greater than the length of the first transition section 14, and a plurality of culture dishes 6 placed on the second conveying member 11 are sequentially conveyed to the third conveying member 12 through the first transition section 14, and at least part of the plurality of culture dishes 6 on the third conveying member 12 are synchronously conveyed to the fourth conveying member 13 through the second transition section 15.

[0050] The first direction may be indicated as a conveying direction of the conveying assembly 1. A plurality of culture dishes 6 may be conveyed in sequence from the second conveying member 11 to the third conveying member 12 to the fourth conveying member 13 along the conveying direction of the conveying assembly 1.

[0051] The third conveying member 12 may be arranged at the same height as the second conveying member 11, and the ends of the third conveying member 12 and the second conveying member 11 that are close to each other may overlap to form the first transition section 14. Similarly, the fourth conveying member 13 may be arranged at the same height as the third conveying member 12, and the ends of the fourth conveying member 13 and the third conveying member 12 that are close to each other may overlap to form the second transition section 15.

[0052] The conveying speed of the conveying assembly 1 can be controlled by adjusting the length of the first transition section 14 and the second transition section 15. For example, the length of the first transition section 14 can correspond to the diameter of one culture dish 6, and the length of the second transition section 15 can correspond to the diameter of four culture dishes 6, so that multiple culture dishes 6 can be sequentially conveyed from the second conveying member 11 to the first transition section 14, and then conveyed from the first transition section 14 to the third conveying member 12, and when conveyed from the third conveying member 12 to the fourth conveying member 13, multiple culture dishes 6 located on the third conveying member 12 can be sequentially conveyed to the second transition section 15, and when there are four culture dishes 6 on the second transition section 15, the fourth conveying member 13 can be started to simultaneously convey the four culture dishes 6 located on the second transition section 15 to the fourth conveying member 13.

[0053] In the above embodiment, the multiple culture dishes 6 on the second conveying member 11 can be sequentially conveyed to the third conveying member 12 via the first transition section 14. When the multiple culture dishes 6 on the third conveying member 12 are conveyed to the second transition section 15, the second transition section 15 can synchronously convey the multiple culture dishes 6 thereon to the third transition section. In this way, when the number of culture dishes 6 conveyed from the first transition section 14 to the third conveying member 12 is large, the second transition section 15 can play a buffering role and control the number of culture dishes 6 conveyed to the fourth conveying member 13, thereby avoiding the situation where the culture dishes 6 are piled up on the conveyor belt assembly, and effectively improving the conveying flexibility and overall conveying efficiency of the conveying assembly 1.

[0054] In some embodiments, Figure 5 and Figure 6 As shown, the bead adding device 3 includes a bead storage bin 31 for storing glass beads and a bead adding assembly 32, the bead storage bin 31 has a discharge port 311, the bead adding assembly 32 is rotatably arranged at the discharge port 311, the bead adding assembly 32 has a turntable 321, a groove 322 with an opening at one end is arranged on the turntable 321, the groove 322 is adapted to accommodate the glass beads, and the culture dish 6 is arranged below the turntable 321; wherein, when the turntable 321 rotates until the opening of the groove 322 is opposite to the culture dish 6, the glass beads in the groove 322 fall into the culture dish 6 under the action of gravity.

[0055] The bead storage bin 31 can be made of materials such as polytetrafluoroethylene (PTFE) or polyetheretherketone (PEEK), which have the characteristics of high temperature resistance and high chemical stability, so as to facilitate high-temperature sterilization of the bead storage bin 31 and the balls in the bead storage bin 31.

[0056] The discharge port 311 may be located at one end of the bead storage bin 31 close to the culture dish 6 , so that the balls in the bead storage bin 31 may fall into the culture dish 6 through the discharge port 311 under the action of gravity.

[0057] The groove 322 may be formed on the side wall of the rotating disk 321, and the groove 322 on the rotating disk 321 may be rotatably connected to the discharge port 311 of the bead storage bin 31 and the culture dish 6, respectively. When the groove 322 on the rotating disk 321 rotates to be connected to the discharge port 311 of the bead storage bin 31, the balls in the bead storage bin 31 may fall into the groove 322 on the rotating disk 321 under the action of gravity, and when the groove 322 on the rotating disk 321 continues to rotate to be connected to the culture dish 6, the balls in the groove 322 may fall into the culture dish 6 under the action of gravity.

[0058] In the above embodiment, the balls in the bead storage bin 31 can fall into the groove 322 on the side wall of the turntable 321. When the groove 322 of the turntable 321 rotates to the culture dish 6, the balls can fall into the culture dish 6 under the action of gravity, thereby realizing automatic bead adding to the culture dish 6, avoiding the contamination of the balls during manual bead adding, effectively shortening the bead adding time, and improving the bead adding efficiency.

[0059] In some embodiments, Figure 7 and Figure 8 As shown, the glass bead coating equipment also includes a labeling positioning device 4, which is arranged between the loading device 2 and the liquid adding device along the conveying component 1, and the labeling positioning device 4 includes a positioning member 41, and the positioning member 41 has a positioning plate 411 movable between a first position and a second position, when the positioning plate 411 moves from the first position to the second position, the positioning plate 411 abuts against the outer edge of the culture dish 6, and when the positioning plate 411 moves from the second position to the first position, the positioning plate 411 is separated from the outer edge of the culture dish 6.

[0060] When the culture dish 6 is transported by the conveying component 1, the culture dish 6 is easily displaced on the conveying component 1 when subjected to external force, thereby affecting subsequent processing operations on the culture dish 6. In this way, when the culture dish 6 moves to the positioning member 41, the positioning plate 411 can move from the first position to the second position, thereby adjusting the position of the culture dish 6 by pushing. When the position adjustment is completed, the positioning plate 411 can move from the second position to the first position.

[0061] The first position and the second position can be respectively represented as different positions of the positioning plate 411. Specifically, when the positioning plate 411 is in the first position, it can be away from the culture dish 6 on the conveying component 1 to avoid the positioning plate 411 affecting the culture dish 6 transported on the conveying component 1. When the positioning plate 411 is in the second position, the positioning plate 411 can be in contact with the culture dish 6 on the conveying component 1 to adjust the position of the culture dish 6.

[0062] The shape of the side of the positioning plate 411 facing the conveying component 1 can be adapted to the shape of the outer edge of the culture dish 6, so that when the positioning plate 411 is in the second position, the positioning plate 411 can stably abut against the outer edge of the culture dish 6, effectively improving the positioning accuracy.

[0063] In the above embodiment, when the position of the culture dish 6 on the conveying component 1 is offset, the positioning plate 411 can move toward the direction of the culture dish 6 so that the positioning plate 411 can abut against the outer edge of the culture dish 6, thereby adjusting the specific position of the culture dish 6 on the conveying component 1 by pushing the culture dish 6, thereby effectively improving the convenience and accuracy of positioning the culture dish 6.

[0064] In some embodiments, Figure 7 As shown, the labeling and positioning device 4 also includes a labeling member 42. The labeling member 42 and the positioning member 41 are arranged on opposite sides of the conveying component 1. The labeling member 42 is used to attach labels to the side walls of the culture dish 6 on the conveying component 1. Before the labeling member 42 attaches the label to the side walls of the culture dish 6, the positioning member 41 moves toward the direction of the conveying component 1 so that the positioning plate 411 is against the outer edge of the culture dish 6.

[0065] The height at which the labeling member 42 is arranged may correspond to the height of the culture dish 6 , so that the labeling member 42 can conveniently attach labels to the side walls of the culture dish 6 .

[0066] When the culture dish 6 is transported by the conveying component 1, the culture dish 6 is easily displaced on the conveying component 1 when subjected to external force, thereby affecting the subsequent labeling operation of the culture dish 6. In this way, the positioning member 41 can move toward the direction of the culture dish 6 and abut against the outer edge of the culture dish 6, thereby correcting the position of the culture dish 6.

[0067] In the above embodiment, the cooperation between the positioning member 41 and the culture dish 6 can avoid the position where the label is posted from being offset or misplaced, thereby effectively improving the accuracy and consistency of label posting.

[0068] In some embodiments, Fig. 9 As shown, the glass bead coating device also includes a material receiving device 5, which is arranged downstream of the bead adding device 3 along the conveying assembly 1. The material receiving device 5 includes a material receiving bin 51 and a supporting member 52. The lower end of the material receiving bin 51 has a material receiving port 511, and the material receiving port 511 allows the culture dishes 6 to pass through and be stacked in the material receiving bin 51. The supporting member 52 is rotatably arranged at the material receiving port 511 and can change the degree of blocking the material receiving port 511 by rotating relative to the material receiving bin 51. The supporting member 52 opens the material receiving port 511 when the lower surface is subjected to an upward force from the culture dish 6; after the culture dish 6 is fed from the material receiving port 511 and moves upward to the first preset position, it falls to the second preset position by gravity, and the supporting member 52 blocks at least part of the material receiving port 511 and supports the culture dish 6 to limit the culture dish 6 to the second preset position.

[0069] The material receiving bin 51 may have a receiving cavity formed along the vertical direction, and the culture dishes 6 may be stacked in sequence in the receiving cavity through a material receiving port 511 below the material receiving bin 51 .

[0070] The supporting member 52 can be rotatably disposed at the material receiving opening 511 of the material receiving bin 51 , and the supporting member 52 can cover at least a portion of the material receiving opening 511 when it is in a horizontal position.

[0071] The first preset position and the second preset position can be respectively represented by different positions of the culture dish 6 in the accommodating cavity of the receiving bin 51. Specifically, the first preset position can be specifically represented by the position when the culture dish 6 moves vertically upward along the receiving port 511 and is separated from the lower surface of the supporting member 52, and the second preset position can be specifically represented by the position when the upper surface of the supporting member 52 supports the culture dish 6.

[0072] In the above embodiment, the culture dish 6 can be abutted against the lower surface of the supporting member 52 and push the supporting member 52 to rotate toward the receiving bin 51, so that the culture dish 6 can move from the receiving port 511 at the lower end of the receiving bin 51 to the receiving bin 51. When the culture dish 6 moves to the first preset position in the receiving bin 51, the culture dish 6 can move to the second preset position under the action of gravity and abut against the upper surface of the supporting member 52, thereby ensuring that the supporting member 52 can support the culture dish 6 and avoid the culture dish 6 from falling from the lower end of the receiving bin 51, effectively reducing the moving distance and transfer risk of the culture dish 6 to the receiving bin 51, and simplifying the mechanical structure of the receiving device 5, thereby realizing the miniaturization of the receiving device 5 and reducing the manufacturing cost and space required for the receiving device 5.

[0073] In some embodiments, the glass bead coating apparatus further includes an adsorption device (not shown in the figure) disposed beside the material receiving device 5 , and the adsorption device is used to transfer the culture dish 6 containing the glass beads to the material receiving bin 51 .

[0074] The adsorption device can be adsorbed on the bottom wall of the culture dish 6 and drive the culture dish 6 to move into the material receiving bin 51 . After the culture dish 6 enters the material receiving bin 51 , the adsorption device can release the culture dish 6 to store the culture dish 6 in the material receiving bin 51 .

[0075] The adsorption device may specifically be a suction cup. Using the suction cup to adsorb the culture dish 6 can not only ensure the firmness of adsorption, but also avoid damage to the surface of the culture dish 6.

[0076] In the above embodiment, the adsorption device can be used to transfer the culture dish 6 containing glass beads to the material receiving bin 51, which not only reduces the steps of manual operation, but also avoids direct contact between the operator and the culture dish 6, effectively improving the material receiving efficiency and safety of the glass bead coating equipment.

[0077] In some embodiments, the loading device 2 and the receiving device 5 are located in the first area, the labeling positioning device 4 is located in the second area, and the liquid adding device and the bead adding device 3 are located in the third area, wherein the air pressure in the space where the first area is located is normal pressure, the air pressure in the space where the second area is located is low positive pressure, and the air pressure in the space where the third area is located is high positive pressure.

[0078] The space where the glass bead coating equipment is located can be divided into a first area, a second area and a third area according to different usage requirements.

[0079] The space in the first area can be in a normal pressure state to facilitate operators to perform routine operations such as loading and unloading. The space in the second area can be in a low positive pressure state, so as to reduce the impact of dust and pollutants on the culture dish 6, thereby improving the accuracy and stability of labeling positioning. The space in the third area can be in a high positive pressure state, so as to further reduce the impact of dust and pollutants on the culture dish 6 during the process of adding liquid and beads to the culture dish 6, thereby ensuring the coating effect of the glass bead coating equipment.

[0080] In the above embodiment, by setting the air pressure in different areas, a suitable environment can be provided for different production steps, thereby greatly improving the coating efficiency and effect of the glass bead coating equipment.
