[0035] The following is a more detailed description of the auxiliary device for microbial detection in cleanroom petri dishes according to the present invention, with reference to the schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the present invention.

[0036] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] like Figs. 1 to 3 As shown in the figure, this utility model embodiment proposes an auxiliary device for microbial detection in cleanroom petri dishes, comprising:

[0038] The storage rack 1 has multiple stacked and independently arranged placement trays 2 in the vertical direction, which are used to support the petri dish body 6. That is, the storage rack 1 serves as a temporary storage area for the petri dish body 6, facilitating subsequent opening and inspection.

[0039] The operating table 3 is located on one side of the storage rack 1 and serves as the opening detection area for the petri dish body 6.

[0040] The transfer mechanism 4 is capable of moving vertically and rotating around its axis. It is used to clamp and transport the culture dish body 6 from the placement tray 2 to the operating table 3, or to clamp and output it from the operating table 3 to the placement tray 2, and to limit the position of the culture dish body 6's container. In other words, the transfer mechanism 4 completes the transfer of the culture dish body 6 between the temporary storage area and the opening detection area while simultaneously limiting the position of the culture dish body 6's container, allowing the subsequent opening mechanism 5 to smoothly open the lid of the culture dish body 6.

[0041] A flip-top mechanism 5 is located on the side of the operating table 3 away from the storage rack 1, and is used to open or close the lid of the culture dish body 6 located on the operating table 3.

[0042] The device sets a storage rack 1 as a temporary storage area of the culture dish body 6, sets an operation table 3 as a cover opening detection area of the culture dish body 6 on the side of the temporary storage area, and sets a transfer mechanism 4 and a cover opening mechanism 5 to realize the movement of the culture dish body 6 in the temporary storage area and the cover opening or closing of the cover body in the cover opening detection area. When the culture dish body 6 needs to be detected, the transfer mechanism 4 can move the culture dish body 6 in the temporary storage area to the cover opening detection area, and the cover body is limited under the action of the transfer mechanism 4. Then, the cover body is opened and closed by the cover opening mechanism 5. Finally, the culture dish body 6 after detection is moved to the corresponding placing tray 2 by the transfer mechanism 4. The above steps are repeated to realize the automatic control of the culture dish body 6 from storage, positioning, cover opening, detection and cover closing without manual operation. In this way, the pollution risk caused by manual operation is eliminated, and the continuous detection demand of the culture dish body 6 in the placing tray 2 of different heights is met, and the detection rate is improved.

[0043] In the embodiment, a specific transfer mechanism 4 is provided to improve the clamping effect of the culture dish body 6.

[0044] Specifically, the transfer mechanism 4 includes a lifting rotary column 41 and a clamping jaw assembly 42 with adjustable spacing.

[0045] The clamping jaw assembly 42 is fixed to the end of the lifting rotary column 41 and is used to clamp the box body of the culture dish body 6.

[0046] Among them, the clamping jaw assembly 42 can be an electric clamping jaw, a pneumatic clamping jaw or a clamping jaw component with a self-locking mechanism. In a specific example, the clamping jaw assembly 42 includes a main body and two clamping arms moving in opposite directions. The clamping arms and the main body can adopt a threaded rod with symmetrical and opposite threads and a driving motor to complete the clamping action. This is a prior art and will not be described here.

[0047] It should be particularly noted that in order to smoothly complete the clamping of the culture dish body 6 by the lifting rotation of the clamping jaw assembly 42, that is, to avoid interference, the placing tray 2 is further limited.

[0048] Specifically, the thickness of the culture dish body 6 is one-half to two-thirds of the spacing between two adjacent placing trays 2, so that a gap is formed between the lower surface of the placing tray 2 and the culture dish body 6 on the lower placing tray 2 for the clamping jaw assembly 42 to enter or exit.

[0049] In other embodiments, in order to further improve the limiting effect of the culture dish body 6, the operation table 3 is further limited.

[0050] Specifically, the edge of the operating table 3 is provided with a flow guiding protrusion 7, and when the gripper assembly 42 drives the culture dish body 6 to rotate and move on the operating table 3, the culture dish body 6 can contact the inner wall of the flow guiding protrusion 7. That is, the stability of the subsequent flipping mechanism 5 is further improved by the dual limiting of the flow guiding protrusion 7 and the gripper assembly 42.

[0051] In addition, a contact sensor is provided at the position where the flow guide protrusion 7 abuts and fits against the culture dish body 6, for detecting whether the culture dish body 6 has reached the preset position.

[0052] Specifically, both the contact sensor and the drive end of the flip-top mechanism 5 are connected to the external control system. That is, the external control system will control the flip-top mechanism 5 to run only after the contact sensor detects that the culture dish body 6 has moved to the preset position, thereby improving the stability of the overall device during operation.

[0053] In other embodiments, a specific flip-top mechanism 5 is proposed to improve the opening and closing effect of the petri dish body 6 lid.

[0054] It should be noted that in the prior art, the culture dish body 6 includes a box and a lid, and the outer diameter of the lid is larger than the inner diameter of the box, so that when the lid is snapped onto the outside of the box, a stepped surface can be formed. In this embodiment, the flip-top mechanism 5 mainly achieves the flip-top function by snapping onto the stepped surface.

[0055] Specifically, the flip-top mechanism 5 includes a flip chuck 51 and a plurality of cylindrical claws 52.

[0056] The flip chuck 51 is rotatably mounted on the side of the operating table 3 away from the storage rack 1, and can be flipped to a horizontal or vertical state.

[0057] Multiple cylindrical claws 52 are disposed on the inner side of the flip chuck 51 (i.e. the side facing the culture dish body 6) for engaging with the cover of the culture dish body 6. The multiple cylindrical claws 52 surround each other to form a semi-circular stepped chamber, which can abut against the stepped surface formed by the box and the cover of the culture dish body 6 to complete the flip operation.

[0058] Furthermore, when the flip chuck 51 is in a horizontal state, the opening of the semi-circular stepped chamber faces the placement tray 2, and the center of the semi-circular stepped chamber and the center of the culture dish body 6 located in the positioning chamber are in the same vertical plane. This ensures that the transfer mechanism 4 can directly input the culture dish body 6 into the semi-circular stepped chamber through the opening, and that the presence of the cylindrical claw 52 will not interfere with the transfer of the culture dish body 6, so that the components can work together.

[0059] It should be noted that the cylindrical clamping jaw 52 is provided with at least three, and preferably four in the embodiment.

[0060] The cylindrical clamping jaw 52 is in a stepped structure, and the outer diameter increases from the direction away from the turnover chuck 51, thereby forming a semicircular stepped cavity between the plurality of cylindrical clamping jaws 52 to complete the opening or closing of the cover body of the culture dish body 6.

[0061] It should be noted that the maximum inner diameter of the semicircular stepped cavity matches the outer diameter of the cover body of the culture dish body 6, and the minimum inner diameter of the semicircular stepped cavity matches the outer diameter of the box body of the culture dish body 6. That is, when the culture dish body 6 is pushed by the transfer mechanism 4, it further ensures that the culture dish body 6 does not interfere with the cylindrical clamping jaw 52, and at the same time, the step surface between the culture dish body 6 and the cover body can abut against the inner wall of the semicircular stepped cavity formed by the plurality of cylindrical clamping jaws 52, so as to facilitate the operation of the subsequent flip operation.

[0062] In other embodiments, the cylindrical clamping jaw 52 can also be provided in a suction cup structure or an electric telescopic clamping jaw structure, which is a prior art. Compared with the above-mentioned mode, in the embodiment, the semicircular stepped cavity formed by the plurality of cylindrical clamping jaws 52 can complete the flip operation without additional power source (such as gas source or electricity) input, thereby reducing the cost and achieving more stable purpose.

[0063] In other embodiments, the flip mechanism 5 further comprises a connecting rod assembly 53, both ends of the connecting rod assembly 53 are connected with the turnover chuck 51 and an external driving member respectively, for controlling the turnover chuck 51 to switch between horizontal state and vertical state. The driving member cooperates with the connecting rod assembly 53 to realize the control of the deflection of the turnover chuck 51, which is a conventional technical means in the prior art, and therefore will not be described here.

[0064] In other embodiments, the clean room culture dish microorganism detection auxiliary device further comprises a support seat, the storage rack 1, the operation table 3 and the transfer mechanism 4 are arranged on the support seat, and the support seat is further provided with a control driving member for controlling the operation of the flip mechanism 5 and the lifting and rotation of the lifting and rotating column 41.

[0065] In a specific example, the control driving member comprises a screw drive and a rotary motor and a cylinder, the screw drive and the rotary motor are used for jacking and rotating the lifting and rotating column 41, and the output end of the cylinder is movably connected with the connecting rod assembly 53, for realizing the deflection control of the turnover chuck 51 by lifting.

[0066] For the convenience of understanding the operation principle of the device, a use method of the petri dish microorganism detection auxiliary device in a clean room is further provided, and specifically includes the following steps:

[0067] The driving transfer mechanism 4 moves the petri dish body 6 on the placing tray 2 to the operation table 3;

[0068] The petri dish body 6 is continuously moved by the transfer mechanism 4 until the inner wall of the guide flow protrusion 7 abuts and fits, at which time the contact sensor sends a signal to the external control system, and the external control system controls the operation of the flip cover mechanism 5 to complete the flip cover operation;

[0069] The detection of the microorganism in the petri dish body 6 is completed by the detection assembly, and when the detection is completed, the flip cover mechanism 5 closes the cover of the petri dish body 6, and the transfer mechanism 4 drives the detected petri dish body 6 to the corresponding placing tray 2;

[0070] The above steps are repeated until the detection of the petri dish body 6 on all placing trays 2 is completed.

[0071] Through the above steps, the full-process automatic control function of the petri dish body 6 from storage, positioning, opening, detection and closing can be realized without manual operation, so as to eliminate the pollution risk caused by human operation, and the continuous detection requirement of the petri dish body 6 in the placing tray 2 of different heights can be met, and the detection rate is improved.

[0072] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Therefore, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
