Description

Technical Field

[0001] This invention relates to the technical field of microbial culture, specifically to a feeding device and a glass bead coating equipment. Background Technology

[0002] When culturing microorganisms, multiple petri dishes need to be placed on a conveyor belt in sequence by manual means. The conveyor belt then transports the petri dishes to the opening and closing device and the microorganism addition device. The lid of each petri dish is then opened and microorganisms are added to the petri dish. In this way, microorganisms can be provided with nutrients while ensuring their diversity.

[0003] However, when placing petri dishes on a conveyor belt, only one petri dish can be placed at a time. If multiple petri dishes are stacked together and placed on the conveyor belt, the equipment for opening and closing the lids and adding microorganisms cannot complete the operations of opening the lids and adding microorganisms on the stack of petri dishes. As a result, the efficiency of placing petri dishes is currently low, and the time cycle for microbial culture is long. Summary of the Invention

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a feeding device is provided. The feeding device includes a conveying component, a dragging component, and a receiving component. The conveying component has a feeding position, a transmission position, and a waiting position arranged sequentially along its conveying direction. Multiple materials are stacked at the feeding position to form a material group. The conveying component drives the material group from the feeding position through the transmission position to the waiting position. The dragging component is disposed near the waiting position. The receiving component is disposed below the dragging component. The dragging component is used to drag the material group located at the waiting position onto the receiving component, and the receiving component is used to transfer each material in the material group dragged by the dragging component to a predetermined position.

[0005] The feeding device of this invention allows multiple materials to be stacked into a material group at the feeding position of the conveyor. The material group can then be moved to a waiting position via the conveyor. A dragging component can smoothly drag the material group at the waiting position onto a receiving component. The receiving component can then disassemble the material group back into multiple materials and pre-position these materials in predetermined positions. This allows for stacked feeding of materials, improving feeding efficiency while ensuring that the material group can be disassembled back into multiple materials after feeding, guaranteeing the feasibility of subsequent operations. This effectively reduces the time required for material feeding and improves feeding efficiency.

[0006] For example, the dragging component includes a first positioning member and a second positioning member. The first positioning member and the second positioning member are respectively disposed on two opposite sides of the material group in the waiting position, and the first positioning member and the second positioning member can move away from or towards the receiving component. The first positioning member and the second positioning member are used to cooperate to drive the material group in the waiting position to move towards the receiving component, so as to drive the material group from the waiting position to the receiving component.

[0007] For example, both the first positioning member and the second positioning member are constructed in the shape of rods, and the first positioning member and the second positioning member cooperate to act on the side of the material group in the waiting position away from the receiving component.

[0008] For example, the receiving assembly includes a support member, which includes a plurality of opposing support bodies. The plurality of support bodies have a first state of being close to each other and a second state of being far apart. In the first state, a first positioning member and a second positioning member cooperate to drag the material group waiting at the position onto the support member. In the second state, the support member releases the supporting force on the material group on the support member, so that the material placed at the bottom of the material group is moved to the predetermined position after being subjected to force.

[0009] For example, the receiving assembly further includes a clamping member located above the support member. The clamping member includes a plurality of opposing clamping bodies, which have a third state of being close to each other and a fourth state of being far apart. In the third state, the clamping member is used to clamp the second material from bottom to top in the material group on the support member. In the fourth state, the clamping member releases the clamping force on the material group on the support member. The clamping member is used at least to switch from the fourth state to the third state when the support member is in the second state.

[0010] For example, the feeding device also includes a transfer member located below the support member. Before the support member switches from the first state to the second state, the transfer member moves toward the support member and passes through the support member to abut against the bottom wall of the material located at the bottommost position on the support member. After the support member switches to the second state, it drives the material at the bottommost position to be transferred to a predetermined position.

[0011] For example, the feeding device further includes a mounting frame for mounting the dragging assembly and the receiving assembly. The receiving assembly also includes a positioning part mounted on the mounting frame. The positioning part is used to cooperate with the first positioning member and the second positioning member to define the material group on the support after the material group in the waiting position is dragged onto the support.

[0012] For example, the feeding device further includes a first support plate and a second support plate respectively disposed on both sides of the conveyor. The first support plate and the second support plate are disposed corresponding to the transmission position. The first support plate and the second support plate respectively form a material support gap with the material group on the transmission position. The material support gap is used to limit the displacement of the material group along a first direction, wherein the first direction is perpendicular to the plate surface of the first support plate.

[0013] For example, the feeding device further includes a first positioning rod and a second positioning rod respectively disposed on both sides of the conveyor, the first positioning rod and the second positioning rod being disposed between the feeding position and the transmission position respectively.

[0014] For example, the feeding device further includes a control unit and a sensing unit. The control unit is electrically connected to the sensing unit and the dragging component, respectively. The sensing unit is disposed next to the waiting position and is used to sense the position information of the material group at the waiting position. The control unit is used to receive the position information and send control commands to the dragging component. The dragging component drags the material group at the waiting position to the receiving component based on the control commands.

[0015] According to another aspect of the present invention, a glass bead coating apparatus is also provided, comprising a switch cover assembly, a coating assembly, and a feeding device as described above, wherein the switch cover assembly and the coating assembly are sequentially disposed downstream of the feeding device.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the present invention more apparent, exemplary embodiments according to the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of the present invention, and not all of the embodiments of the present invention. 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 herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of the present invention.

[0024] In the following description, numerous details are provided to enable a thorough understanding of the invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the invention, and that the invention can be practiced without one or more of these details. Furthermore, to avoid obscuring the invention, some technical features well-known in the art have not been described in detail.

[0025] 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. Preferred embodiments of the present invention are described in detail below; however, in addition to these detailed descriptions, the present invention may have other embodiments.

[0026] One embodiment of the present invention provides a feeding device that can effectively reduce the time required for material feeding and improve material feeding efficiency. The feeding device according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2As shown, the feeding device includes a conveyor 1, a dragging assembly 3, and a receiving assembly 4. The conveyor 1 has a feeding position 11, a transmission position 12, and a waiting position 13 arranged sequentially along its conveying direction. Multiple materials are stacked at the feeding position 11 to form a material group 2. The conveyor 1 drives the material group 2 from the feeding position 11 through the transmission position 12 to the waiting position 13. The dragging assembly 3 is positioned close to the waiting position 13. The receiving assembly 4 is positioned below the dragging assembly 3. The dragging assembly 3 is used to drag the material group 2 located at the waiting position 13 onto the receiving assembly 4, and the receiving assembly 4 is used to transfer each material in the material group 2 dragged by the dragging assembly 3 to a predetermined position.

[0028] The conveyor 1 can be a conveyor belt. The conveyor belt moves along its conveying direction and is sequentially provided with a loading position 11, a transmission position 12 and a waiting position 13. The operator can stack multiple materials into a pile to form a material group 2 and place it on the loading position 11 of the conveyor belt.

[0029] When the material group 2 moves from the loading position 11 to the waiting position 13 under the drive of the conveyor 1, at least part of the dragging component 3 can move towards the material group 2 and act on the material group 2, thereby dragging the material group 2 onto the receiving component 4. Then, the receiving component 4 can be used to disperse the material group 2 and transfer each material to the predetermined position in sequence.

[0030] The predetermined position can be determined according to the actual usage. Specifically, a conveyor belt can be set on the side of the receiving component 4. The receiving component 4 can disperse the material group 2 located on it and transfer each material to the conveyor belt in sequence, and then the conveyor belt will transport the material to the predetermined position.

[0031] In this invention, the feeding device allows multiple materials to be stacked into a material group 2 at the feeding position 11 of the conveyor 1. The material group 2 can then be moved from the conveyor 1 to the waiting position 13 via the transmission position 12. The dragging component 3 can smoothly drag the material group 2 located at the waiting position 13 onto the receiving component 4. The receiving component 4 can then disassemble the material group 2 back into multiple materials and pre-position these materials in predetermined locations. This allows for stacked feeding of materials, improving feeding efficiency while ensuring that the material group 2 can be disassembled back into multiple materials after feeding, guaranteeing the feasibility of subsequent operations. This effectively reduces the time required for material feeding and improves feeding efficiency.

[0032] In some embodiments, such as Figure 1 and Figure 2As shown, the dragging component 3 includes a first positioning member 31 and a second positioning member 32. The first positioning member 31 and the second positioning member 32 are respectively disposed on two opposite sides of the material group 2 in the waiting position 13, and the first positioning member 31 and the second positioning member 32 can move away from or towards the receiving component 4. The first positioning member 31 and the second positioning member 32 are used to cooperate to drive the material group 2 in the waiting position 13 to move towards the receiving component 4, so as to drive the material group 2 from the waiting position 13 to the receiving component 4.

[0033] The drag-and-drop component 3 may include a first drive member 33 and a second drive member 34 respectively, which are respectively provided corresponding to the first positioning member 31 and the second positioning member 32. The first drive member 33 can be connected to the first positioning member 31 through a third drive member 35, and the second drive member 34 can be connected to the second positioning member 32 through a fourth drive member 36.

[0034] like Figure 2 As shown, the first driving member 33 can drive the third driving member 35 and the first positioning member 31 to move away from or towards the receiving assembly 4, while the third driving member 35 can drive the first positioning member 31 to move away from or towards the conveying member 1. Similarly, the second driving member 34 can drive the fourth driving member 36 and the second positioning member 32 to move away from or towards the receiving assembly 4, while the fourth driving member 36 can drive the second positioning member 32 to move away from or towards the conveying member 1. Specifically, the first driving member 33, the second driving member 34, the third driving member 35, and the fourth driving member 36 can be cylinders or other devices capable of driving the first positioning member 31 and the second positioning member 32, etc., and this application does not specifically limit their use.

[0035] The first positioning member 31 and the second positioning member 32 can move to the side of the material group 2 away from the receiving component 4 on the waiting position 13 under the drive of the first driving member 33 and the second driving member 34, respectively. Then the third driving member 35 and the fourth driving member 36 can drive the first positioning member 31 and the second positioning member 32 to move towards the conveyor 1, so as to abut against the side wall of the material group 2. At this time, the first positioning member 31 and the second positioning member 32 can move towards the receiving component 4 under the drive of the first driving member 33 and the second driving member 34, until the material group 2 is dragged onto the receiving component 4.

[0036] In the above embodiments, the position of the material group 2 can be precisely controlled through the cooperation of the first positioning member 31 and the second positioning member 32, ensuring that the material group 2 can move accurately onto the receiving component 4, effectively guaranteeing the reliability of the feeding device. Furthermore, it can reduce manual intervention and effectively improve the automation level and feeding efficiency of the feeding device.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, both the first positioning member 31 and the second positioning member 32 are constructed in the shape of rods, and the first positioning member 31 and the second positioning member 32 cooperate to act on the side of the material group 2 of the waiting position 13 away from the receiving component 4.

[0038] The lengths of the first positioning member 31 and the second positioning member 32 can correspond to the height of the material group 2. In this way, when the material group 2 is dragged using the first positioning member 31 and the second positioning member 32, the first positioning member 31 and the second positioning member 32 can respectively form an abutment action with each material in the material group 2, thereby ensuring the stability during the dragging process and preventing the material group 2 from tipping over.

[0039] In the above embodiments, the rod-shaped first positioning member 31 and the second positioning member 32 have simple structures, are easy to manufacture and maintain, and greatly reduce the manufacturing cost of the dragging component 3 while ensuring the dragging effect of the dragging component 3.

[0040] In some embodiments, such as Figure 3 As shown, the receiving component 4 includes a support member 41, which includes multiple opposing support bodies. The multiple support bodies have a first state of being close to each other and a second state of being far apart. In the first state, the first positioning member 31 and the second positioning member 32 cooperate to drag the material group 2 of the waiting position 13 onto the support member 41. In the second state, the support member 41 removes the supporting force on the material group 2 on the support member 41, so that the material placed at the bottom of the material group 2 is moved to the predetermined position after being subjected to force.

[0041] like Figure 3 As shown, the support member 41 may include a first support body 411 and a second support body 412 that move towards each other. The first support body 411 and the second support body 412 can approach each other to form a first state. In the first state, the first positioning member 31 and the second positioning member 32 cooperate to drag the material group 2 located on the waiting position 13 onto the support surface formed by the first support body 411 and the second support body 412. The first support body 411 and the second support body 412 can move away from each other to form a second state. In the second state, the first support body 411 and the second support body 412 can release the supporting force on the material group 2, so that each material in the material group 2 can be sequentially transferred from bottom to top to a predetermined position.

[0042] In the above embodiments, the support member 41 can flexibly switch between the first state and the second state, thereby enabling the application and removal of support force on the material group 2, reducing manual intervention, effectively improving the automation level of the feeding device, as well as its ease of use and practicality.

[0043] In some embodiments, such as Figure 3As shown, the receiving assembly 4 also includes a clamping member 42, which is located above the support member 41. The clamping member 42 includes multiple clamping bodies that move in opposite directions. The multiple clamping bodies have a third state of being close to each other and a fourth state of being far apart. In the third state, the clamping member 42 is used to clamp the second material from bottom to top in the material group 2 on the support member 41. In the fourth state, the clamping member 42 releases the clamping force on the material group 2 on the support member 41. The clamping member 42 is used at least to switch from the fourth state to the third state when the support member 41 is in the second state.

[0044] like Figure 3 As shown, the clamping member 42 may include a first clamping body 421 and a second clamping body 422 that move toward each other. The first clamping body 421 and the second clamping body 422 may approach each other and apply a clamping force to the material group 2 to form a third state, and the first clamping body 421 and the second clamping body 422 may move away from each other and remove the clamping force applied to the material group 2 to form a fourth state.

[0045] When the support member 41 is in the first state, the first positioning member 31 and the second positioning member 32 can cooperate to drag the material group 2 of the waiting position 13 onto the support member 41. At this time, the clamping member 42 can be in the third state to limit the displacement of the second material and above from bottom to top in the material group 2. Then, the support member 41 can switch from the first state to the second state, thereby transferring the material at the bottom of the material group 2 to the predetermined position. After the transfer is completed, the support member 41 can switch from the second state to the first state, and the clamping member 42 can switch from the third state to the fourth state. At this time, the remaining material in the material group 2 can fall onto the support member 41 under the action of gravity. The feeding device can repeat the above operation to transfer each material in the material group 2 to the predetermined position in sequence.

[0046] In the above embodiments, the clamping member 42 can flexibly switch between the third state and the fourth state, and with the cooperation of the supporting member 41, each material in the material group 2 can be transferred to the predetermined position in sequence, which effectively improves the convenience and efficiency of the feeding device and greatly enhances the practicality of the feeding device.

[0047] In some embodiments, such as Figure 3 As shown, the feeding device also includes a transfer member 43, which is located below the support member 41. Before the support member 41 switches from the first state to the second state, the transfer member 43 moves towards the support member 41 and passes through the support member 41 to abut against the bottom wall of the material located at the bottom of the support member 41. After the support member 41 switches to the second state, it drives the material at the bottom to be transferred to the predetermined position.

[0048] The transfer component 43 can be a suction cup. The suction cup can be used to adsorb materials, which can avoid damage to the surface of the materials. It is especially suitable for fragile objects or objects whose surfaces need to be kept intact.

[0049] When the support member 41 is in the first state, the transfer member 43 can pass through the gap between the first support body 411 and the second support body 412 and abut against the bottom wall of the material at the bottom of the material group 2, so that a stable connection is formed between the transfer member 43 and the material. Then, when the support member 41 is in the second state, the transfer member 43 can drive the material to move away from the material group 2 and transfer it to a predetermined position.

[0050] In the above embodiments, the transfer member 43 can quickly transfer each material in the material group 2 to a predetermined position, thereby replacing manual operation, reducing labor costs, and further improving the automation level of the feeding device as well as the feeding speed and efficiency.

[0051] In some embodiments, such as Figure 3 As shown, the feeding device also includes a mounting frame 5 for mounting the dragging assembly 3 and the receiving assembly 4. The receiving assembly 4 also includes a positioning part 44 mounted on the mounting frame 5. The positioning part 44 is used to cooperate with the first positioning member 31 and the second positioning member 32 to limit the material group 2 on the support member 41 after the material group 2 of the waiting position 13 is dragged onto the support member 41.

[0052] The dragging component 3 and the receiving component 4 can be arranged sequentially on the mounting frame in a vertical direction, and the positioning part 44 can be arranged on the mounting frame 5, away from the side of the loading position 11.

[0053] like Figure 3 As shown, the positioning part 44 can be rod-shaped, and there can be two positioning parts 44. The two rod-shaped positioning parts 44 can be respectively arranged on opposite sides of the material group 2. In this way, the two positioning parts 44 can form a limiting cavity with the first positioning member 31 and the second positioning member 32. When the material group 2 is located on the support member 41, the limiting cavity can limit the tilt of the material group 2 to avoid the material group 2 located on the support member 41 from overturning.

[0054] By cooperating with the positioning part 44, the first positioning member 31 and the second positioning member 32, the accurate position of the material group 2 on the support member 41 can be ensured, thereby ensuring that the clamping member 42 can stably and firmly clamp the material group 2.

[0055] In the above embodiments, the cooperation between the positioning part 44, the first positioning member 31, and the second positioning member 32 can prevent the material group 2 from shifting or tilting when it is dragged from the waiting position 13 onto the support member 41, effectively ensuring the stability of the material group 2. Furthermore, the positioning part 44 can also limit the specific position of the material group 2 on the support member 41, thereby ensuring stable clamping by the clamping member 42 and further improving the safety and reliability of the feeding device.

[0056] In some embodiments, such as Figure 1 and Figure 2 As shown, the feeding device also includes a first support plate 6 and a second support plate 7 respectively disposed on both sides of the conveyor 1. The first support plate 6 and the second support plate 7 are disposed corresponding to the transmission position 12. The first support plate 6 and the second support plate 7 respectively form a material support gap with the material group 2 on the transmission position 12. The material support gap is used to limit the displacement of the material group 2 along a first direction, wherein the first direction is perpendicular to the plate surface of the first support plate 6.

[0057] In the above embodiment, when the material group 2 moves from the loading position 11 of the conveyor 1 to the waiting position 13, the material group 2 may shake or tilt. The first support plate 6 and the second support plate 7 set at the corresponding transmission position 12 can ensure that the material group 2 passes smoothly, while also limiting the displacement of the material group 2 along the first direction, avoiding the material group 2 from tipping over or tilting during the movement, thus ensuring the stability of the movement of the material group 2 and further improving the reliability and safety of the loading device.

[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the feeding device also includes a first positioning rod 8 and a second positioning rod 9 respectively disposed on both sides of the conveyor 1, with the first positioning rod 8 and the second positioning rod 9 respectively disposed between the feeding position 11 and the transmission position 12.

[0059] The first positioning rod 8 and the second positioning rod 9 can be respectively connected to a fifth driving member 81 and a sixth driving member 91. The fifth driving member 81 and the sixth driving member 91 can respectively drive the first positioning rod 8 and the second positioning rod 9 to move closer to or further away from the conveyor 1. Specifically, the fifth driving member 81 and the sixth driving member 91 can be a cylinder or other device capable of driving the first positioning rod 8 and the second positioning rod 9 to move, etc., and this application does not make specific limitations in this regard.

[0060] When the material group 2 moves from the loading position 11 to the transmission position 12, the first positioning rod 8 and the second positioning rod 9 can move towards the conveyor 1 under the drive of the fifth driving member 81 and the sixth driving member 91, respectively. In this way, while ensuring that the material group 2 can pass smoothly, it can also abut against the side wall of the material group 2, thereby ensuring that each material in the material group 2 can be neatly stacked in the vertical direction.

[0061] In the above embodiments, the first positioning rod 8 and the second positioning rod 9 can finely adjust the position of the materials in the material group 2 to avoid the stacked materials from tilting, which greatly improves the stability of the material group 2 during the conveying process.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the feeding device also includes a control unit and a sensing unit 10. The control unit is electrically connected to the sensing unit 10 and the dragging component 3 respectively. The sensing unit 10 is located next to the waiting position 13. The sensing unit 10 is used to sense the position information of the material group 2 on the waiting position 13. The control unit is used to receive the position information and send control commands to the dragging component 3. The dragging component 3 drags the material group 2 on the waiting position 13 to the receiving component 4 based on the control commands.

[0063] The control components can specifically be processor chips and their peripheral circuits such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs). This application does not specifically limit them.

[0064] The sensing element 10 can be a proximity sensor or an infrared sensor, etc. This application does not make a specific limitation. Any device that can sense the position information of the material group 2 on the waiting position 13 is acceptable.

[0065] In the above embodiment, when the material group 2 moves to the waiting position 13, the sensing element 10 can sense the position information of the material group 2, and the control element sends a control command to the dragging component 3, thereby realizing the automated control of the feeding process of the feeding device and reducing manual intervention. Furthermore, the automated feeding process can significantly improve the efficiency of material feeding and ensure the smoothness of the feeding process.

[0066] According to another aspect of the present invention, a glass bead coating apparatus is also provided, comprising a switch cover assembly, a coating assembly, and a feeding device as described above, wherein the switch cover assembly and the coating assembly are sequentially disposed downstream of the feeding device. The coating assembly is used to inoculate bacterial strains by moving glass beads with bacterial strains adhering to them on the culture medium during bacterial culture. The trajectory of the glass beads moving on the culture medium can be understood as coating.

[0067] When adding beads to a petri dish using a glass bead coating device, the feeding device can be used to store and transport the petri dish to the opening and closing assembly, which can open the lid of the petri dish so that the coating assembly can add beads into the petri dish.

[0068] The glass bead coating equipment of the present invention includes the feeding device as described above. Since the feeding device has the beneficial effects described above, the glass bead coating equipment including the feeding device as described above must also have the beneficial effects described above.

[0069] Although exemplary embodiments have been described herein with reference to the accompanying drawings, it should be understood that the above exemplary embodiments are merely illustrative and are not intended to limit the scope of the invention. Various changes and modifications can be made therein by those skilled in the art without departing from the scope and spirit of the invention. All such changes and modifications are intended to be included within the scope of the invention as claimed in the appended claims.
