Thus, other examples of the exemplary embodiments may have different values. It should be noted that in the following drawings, similar symbols and letters indicate similar items. Thus, once an item is defined in one drawing, there is no need to further discuss it in subsequent drawings.

[0029] 1 to 5, the transport mechanism of this embodiment includes a frame 10, a movable plate 20, and a first mounting table 30. The movable plate 20 is provided on the frame 10 so as to be movable laterally, and has a consumables receiving position located above the frame 10, and a consumables taking-in position protruding forward beyond the frame 10. The first mounting table 30 is provided on the movable plate 20 so as to be movable vertically.

[0030] When the technical aspect of this embodiment is applied, the transport mechanism includes a frame 10 and a movable plate 20 movably provided on the frame 10. When the transport mechanism is attached, the frame 10 can be fixed within one area, and the movable plate 20 can move along the lateral direction and has a consumable receiving position and a consumable taking-in position, so that the movable plate 20 can realize the transport of the consumable while moving. In addition, the movable plate 20 of the transport mechanism is further provided with a first mounting table 30 on which the consumable can be placed, and when the transport mechanism transports consumables of different heights, the height of the first mounting table 30 can be adjusted, so that the difference in height between the designated positions of the different consumables (the positions to which the consumables should be transported, and after the consumables are transported to the designated positions, the pickup device can cooperate with the consumables to grasp them) can be reduced, and such an installation form can reduce the difficulty of picking up by the pickup device, reduce the design difficulty and processing cost of the pickup device, and ultimately contribute to reducing the processing cost of the nucleic acid detection device.

[0031] The above-mentioned "lateral direction" refers to the front-rear direction shown in FIG.

[0032] As shown in FIG. 1 to FIG. 5, in this embodiment, the transport mechanism further includes a second mounting table 40, which is provided on the movable plate 20 and located outside the first mounting table 30 in the circumferential direction. The first mounting table 30 has an elevated position that is higher than the second mounting table 40 and a lowered position that is lower than the second mounting table 40. In the above structure, since the transport mechanism needs to transport different consumables, if the occupying area of ​​the consumables to be transported is small, it can be placed on the first mounting table 30. If the occupying area of ​​the consumables to be transported is large, the first mounting table 30 can be moved to a lowered position so that the consumables can be placed on the second mounting table 40. With the above structure, the transport mechanism can select an appropriate mounting table according to the size of the consumables to be transported, thereby increasing the stability of the consumables during transport.

[0033] The above-mentioned phrase "the second mounting table 40 is provided on the movable plate 20 and is positioned circumferentially outside the first mounting table 30" means that the second mounting table 40 can completely surround the first mounting table 30 or can partially surround it.

[0034] In this embodiment, the consumables include an amplification plate and an extraction plate. The amplification plate has a small occupancy area and can be transported by the first mounting table 30. The periphery of the first mounting table 30 is located outside the periphery of the amplification plate, so that the probability of the edge of the amplification plate being touched during transportation can be reduced, and the amplification plate can be stably placed at a predetermined position, so that the pickup device can smoothly pick up the amplification plate. On the other hand, the extraction plate has a large occupancy area and can be transported by the second mounting table 40. The periphery of the second mounting table 40 is located outside the periphery of the extraction plate, so that the probability of the edge of the extraction plate being touched during transportation can be reduced, and the extraction plate can be stably placed at a predetermined position, so that the pickup device can smoothly pick up the extraction plate.

[0035] In another embodiment (not shown), the first mounting table 30 further has a flush position where it is flush with the second mounting table 40.

[0036] As shown in FIG. 1 to FIG. 5, in this embodiment, the second mounting table 40 is fixed to the movable plate 20. In the above structure, the second mounting table 40 is used to transport an extraction plate that is taller than an amplification plate. For this reason, the second mounting table 40 is fixed and the first mounting table 30 is movable along the vertical direction, and the height of the first mounting table 30 is increased, so that the difference in height between the designated positions of different consumables can be reduced, making it easier to pick up the consumables by the pick-up device. The above installation form contributes to reducing the production cost of the second mounting table 40, reducing the production cost of the transport device, and ultimately reducing the production cost of the nucleic acid detection device.

[0037] Of course, in other embodiments not shown, the second mounting table 40 may be provided to be movable along the vertical direction on the movable plate 20. The above-mentioned installation form can increase the degree of freedom of the second mounting table 40, increase the types of consumables that can be transported by the transport device, and contribute to improving the versatility of the transport mechanism.

[0038] 1 to 5, in this embodiment, the first mounting table 30 includes a first mounting plate 31 located above the movable plate 20, and a first drive structure 32 provided between the first mounting plate 31 and the movable plate 20, and the first drive structure 32 can drive the first mounting plate 31 to move in the vertical direction. In the above structure, the first drive structure 32 drives the first mounting plate 31 to rise and fall, thereby improving the automation level of the transport mechanism and improving the transport efficiency of consumables.

[0039] As shown in FIG. 1 to FIG. 5, in this embodiment, the second mounting table 40 includes a second mounting plate 41 located above the movable plate 20 and a support 42 that fixedly connects the movable plate 20 and the second mounting plate 41, and the first drive structure 32 is provided on the support 42. The second mounting plate 41 is provided with an attachment hole 411, and the projection of the second mounting plate 41 onto the horizontal plane surrounds the outer periphery of the projection of the first mounting plate 31 onto the horizontal plane. In the above structure, the second mounting plate 41 is supported by the support 42, so that the second mounting plate 41 can be stably connected. The first drive structure 32 is attached to the support 42, and the first mounting plate 31 can enter the attachment hole 411. With the above structure, the layout of the first mounting table 30 and the second mounting table 40 becomes compact, which contributes to reducing the space occupied by the transport mechanism, and thus allows the nucleic acid detection device to be designed compactly.

[0040] The second placement plate 41 has a U-shaped structure.

[0041] As shown in FIG. 2 to FIG. 5, in this embodiment, the first driving structure 32 includes a driving motor 321, a driving gear 322, and a rack structure 323.

The driving gear 322 is extrapolated to the driving shaft of the driving motor 321 and rotates in synchronization with the driving shaft of the driving motor 321. A first end of the rack structure 323 is fixedly connected to the first placement plate 31, and the rack structure 323 is provided in mesh with the driving gear 322. In the above structure, the driving motor 321 moves the rack structure 323 up and down via the driving gear 322 to move the first placement plate 31 in the vertical direction, and the above structure is simple, has low production costs, and has high driving stability.

[0042] 5, in this embodiment, the first mounting table 30 further includes a first guide structure 50, which includes a slide rail 51 and a slider 52 slidably provided on the slide rail 51, the slide rail 51 being provided on the support, and the slider 52 being provided on the second end of the rack structure 323. In the above structure, the first guide structure 50 can further increase the movement stability of the rack structure 323, and ensure the movement stability of the first mounting plate 31.

[0043] 1, in this embodiment, the first mounting table 30 is provided on the first mounting plate 31 and further includes a first position restriction structure 33 that engages with the first consumable 110 for position restriction. In the above structure, the first consumable 110 is an amplification plate, and the first position restriction structure 33 can engage with the amplification plate for position restriction, ensuring the stability of the amplification plate during transportation.

[0044] Specifically, as shown in Figs. 2, 3 and 5, in this embodiment, the first position restriction structure 33 includes a plurality of position restriction columns 331 provided on the first mounting table 30. Specifically, the amplifier plate is a separate structure including an amplifier plate body 112 and a cover plate 111 provided on the amplifier plate body 112. The amplifier plate body 112 includes a top plate and side plates provided in the circumferential direction of the top plate, and the top plate is provided with a plurality of downward through holes, and one tapered tube is attached below each through hole. The plurality of position restriction columns 331 are located within a frame surrounded by the side plates, and a tapered groove is provided on the upper surface of each position restriction column 331, and the tapered groove engages with the tapered tube for position restriction, thereby realizing position restriction for the amplifier plate.

[0045] 2, 3 and 5, in this embodiment, the first position restriction structure 33 further includes a plurality of position restriction ribs 332 provided on the first mounting table 30, and the plurality of position restriction ribs 332 are provided at intervals on the periphery of the first mounting plate 31. In the above structure, the plurality of position restriction ribs 332 can restrict the position of the periphery of the amplification plate, and similarly, can ensure the stability of the amplification plate during transportation.

[0046] 2, 3 and 5, in this embodiment, the position restriction ribs 332 are located circumferentially outside the position restriction columns 331, and the position restriction ribs 332 and the position restriction columns 331 are provided at intervals. In the above structure, the position restriction columns 331 engage with the amplifier plate main body 112 for position restriction, and the position restriction ribs 332 engage with the cover plate 111 for position restriction, and the position restriction ribs 332 and the position restriction columns 331 are provided at intervals, so that when the amplifier plate main body 112 is placed on the first mounting plate 31, the position restriction ribs 332 do not interfere with the amplifier plate main body 112. Accordingly, when the cover plate 111 is placed on the first mounting plate 31, the position restriction columns 331 do not interfere with the cover plate 111.

[0047] Here, the amplification plate main body 112 and the cover plate 111 need to be transported separately, and the plurality of position control columns 331 engage with the amplification plate main body 112 for position control, and the plurality of position control ribs 332 engage with the cover plate 111 for position control.

[0048] When the amplification plate main body 112 is placed on the first mounting table and engaged with the multiple position restricting columns 331 to restrict its position, the multiple position restricting ribs 332 are positioned on the outer side of the amplification plate main body 112 in the circumferential direction.

[0049] 5 and 6, in this embodiment, the upper surface of each position restricting rib 332 is an inclined surface 3321 that gradually slopes downward from the outside to the inside of the first mounting table 30. In the above structure, the inclined surface 3321 can serve to guide the cover plate 111 of the amplification plate, and when the edge of the cover plate 111 is placed on the inclined surface 3321, the cover plate 111 slides down due to the guide of the inclined surface 3321 and can be restricted in position by the inner wall of the position restricting rib 332, so that the cover plate 111 can be stably placed on the first mounting table 30.

[0050] As shown in FIG. 1, FIG. 4 and FIG. 5, in this embodiment, the second mounting table 40 further includes a second position restriction structure 43, which is provided on the second mounting plate 41 and engages with the second consumable 120 for position restriction. When the first mounting table 30 is in the lowered position, the first position restriction structure 33 is lower than the second mounting plate 41. In the above structure, the second consumable 120 is an extraction plate, and the extraction plate is provided with an engagement structure that engages with the second position restriction structure 43. Specifically, the extraction plate is provided with a plurality of tapered tubes extending downward, and the second position restriction structure 43 is a plurality of position restriction columns, and a tapered groove is provided on the upper surface of each position restriction column, and the tapered groove engages with the tapered tube for position restriction, thereby realizing position restriction with respect to the extraction plate. In addition, in order to prevent the first position regulating structure 33 of the first mounting table 30 from interfering with the extraction plate when the extraction plate is placed on the second mounting table 40, the first position regulating structure 33 needs to be lower than the second mounting plate 41 when the first mounting table is in the lowered position.

[0051] 1, in this embodiment, the transport mechanism further includes a second guide structure 60, which is provided between the frame 10 and the movable plate 20, and the movable plate 20 is provided movably on the frame 10 via the second guide structure 60.

In the above structure, the second driving structure 70 can be controlled by a control program to drive the movable plate 20 to move between the consumable receiving position and the consumable input position, thereby improving the automation level of the transport mechanism.

[0053] 7, the nucleic acid detection device of this embodiment includes a base, a partition structure 90, and a transport mechanism 100. The base includes a first region 1 and a second region 2 provided adjacent to each other. The partition structure 90 is provided between the first region 1 and the second region 2, and separates the first region 1 from the second region 2. The partition structure 90 includes a pivot door 91, which has an open position that connects the first region 1 and the second region 2, and a closed position that separates the first region 1 from the second region 2. The transport mechanism 100 is the transport mechanism described above, and the frame 10 of the transport mechanism 100 is provided in the second region 2. When the movable plate 20 of the transport mechanism 100 is in the consumable receiving position, the movable plate 20 is located in the second region 2, and when the movable plate 20 is in the consumable taking-in position, the movable plate 20 is located in the first region 1. When the movable plate 20 moves from the consumable receiving position to the consumable taking-in position, the movable plate 20 can perform a push operation in cooperation with the pivot door 91. In the above structure, the partition structure 90 contributes to physically separating the first region 1 and the second region 2. In addition, the partition structure 90 includes a pivot door 91, and when the transport mechanism 100 moves from the consumable receiving position to the consumable taking-in position, the movable plate 20 of the transport mechanism 100 can perform a push operation in cooperation with the pivot door 91. This ensures smooth movement of the transport mechanism 100 across the regions.

[0054] The first area 1 is a reagent placement area for preparing sample extraction reagents and sample amplification reagents, and is a low-contamination area since the reagent placement area does not contain a detection sample. The second area 2 is a sample extraction area for placing a detection sample and a sample extraction reagent, and extraction of the detection sample is completed in this area, making this area a medium-contamination area.

[0055] 7, in this embodiment, the tip of the movable plate 20 protrudes further forward than the tip of the first mounting table 30 and also protrudes further forward than the tip of the second mounting table 40. With the above structure, the movable plate 20 can contact the pivot door 91 before the first mounting table 30 and the second mounting table 40 do, so that it is possible to prevent the pickup device from being unable to accurately grasp the consumables due to the consumables placed on the first mounting table 30 or the second mounting table 40 contacting the pivot door 91 before the movable plate 20, thereby changing the position of the consumables.

[0056] In describing the present invention, it should be understood that orientations or positional relationships indicated by directional terms such as "front, back, up, down, left, right", "sideways, lengthways, vertical, horizontal", "top, bottom" and the like are generally based on orientations or positional relationships shown in the drawings, and are merely for the purpose of making the present invention easier to describe and simplifying the description, and that, unless otherwise stated, these directional terms do not indicate or imply that the devices or elements shown have a particular orientation or must be configured and operated in a particular orientation, and therefore should not be understood as limiting the scope of protection of the present invention. Also, the directional terms "inside, outside" refer to the inside and outside of the contour of each member itself.

[0057] For purposes of explanation, spatially relative terms, such as "on...," "above...," "on top of...," "above," and the like, may be used herein to describe the spatial location of a device or feature as depicted in the figures relative to other devices or features. It should be understood that spatially relative terms are intended to include different orientations of use or operation of the device other than the depicted orientation. For example, if a device in the drawings is inverted, a device described as "above other devices or structures" or "on top of other devices or structures" would be described as "below other devices or structures" or "under other devices or structures" after being inverted. Thus, the illustrative term "above..." can include two orientations: "above..." and "below...." The device may be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein should be interpreted accordingly.

[0058] In addition, the use of terms such as "first" and "second" to define parts is merely for the purpose of making it easier to distinguish corresponding parts. Unless otherwise explained, the above terms have no special meaning and should not be understood as limiting the scope of protection of the present invention.

[0059] The above is merely a preferred embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art can make various modifications and variations to the present invention. Any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included within the protection scope of the present invention.
