Mycotoxin contamination has become one of the important limiting factors for the sustainable development of agriculture and seriously threatens the health of humans and animals.

[0003] The patent No. CN202223328745.X discloses a device for detecting multiple fluorescence cards, including a thermostatic plate fixedly installed above a bottom plate. A plurality of card slot members are installed on the thermostatic plate, and the plurality of card slot members are arranged in a row. An insertion card slot is formed between the card slot members and the thermostatic plate, and a detection hole is provided at the top of the card slot member; a long strip-shaped micro switch circuit board is installed at the rear of the card slot member, and an optical detection module is installed above the card slot member. The optical detection module is driven by a screw translation module to perform horizontal reciprocating translation. The screw translation module is fixedly arranged above the bottom plate and is located behind the micro switch circuit board. It realizes the picking, placing and replacement of multiple fluorescence test cards through the side of the device, improves the flexibility of the detection process, and drives the optical detection module to translate through the translation module, so that the optical detection module performs one-by-one detection of the fluorescence test cards in the vertical direction to ensure the detection accuracy.

[0005] By controlling the forward and reverse rotation of the motor to drive the optical detection module to reciprocate and scan, the frequent forward and reverse rotation of the motor will affect its accuracy, making the optical detection module unable to align with the detection hole;

[0006] During the picking and placing process of the fluorescence test card, the optical detection module is connected to the external environment, and dust in the environment will enter and affect the detection accuracy of the optical detection module. Summary of the Invention

[0007] The purpose of the utility model is to provide a rapid detection device for mycotoxins aiming at the problem that in the prior art, the frequent forward and reverse rotation of the motor will affect its accuracy, making the optical detection module unable to align with the detection hole.

[0008] To achieve the above purpose, the utility model adopts the following technical solutions: A rapid detection device for mycotoxins, which includes:

[0009] A housing, having a cylindrical structure.

[0010] A light-transmitting plate is located in the middle of the housing, dividing the housing into upper and lower parts. The housing adopts a cylindrical structure and is divided into upper and lower parts by the light-transmitting plate inside, making the overall structure compact and the functional areas clearly defined. The upper layer of the housing is a sealed cavity. The optical detection module rotates and scans in the sealed cavity to avoid the optical detection module communicating with the external environment during the detection process. Dust in the environment will enter and affect the detection accuracy of the optical detection module.

[0011] An optical detection module is located in the upper part of the housing and is used to detect the fluorescence test card.

[0012] A rotating mechanism is installed on the light-transmitting plate and serves as a carrier for mounting the optical detection module.

[0013] A driving mechanism is located at the top of the housing and is used to drive the rotating mechanism to rotate. The driving mechanism includes a driving part and a sector-shaped turbine adapted to the rotating mechanism. The driving part is vertically installed at the top of the housing and is connected to the sector-shaped turbine. The sector-shaped turbine meshes with the rotating mechanism. The driving mechanism drives the rotating mechanism through the driving part and the sector-shaped turbine, so that the optical detection module can rotate flexibly.

[0014] A card slot plate is located at the bottom of the housing and is used to accommodate the fluorescence test card.

[0015] Furthermore, the rotating mechanism includes a bearing seat, a rotating shaft, a gear, and a rotating disk for mounting the optical detection module. The bearing seat is installed on the light-transmitting plate and is connected to the rotating shaft. The rotating shaft is provided with a gear meshing with the sector-shaped turbine and a rotating disk from top to bottom.

[0016] The use of the bearing seat ensures the stable operation of the rotating shaft, while reducing friction and wear. This helps to improve the service life and reliability of the device, and ensures the stability of the optical detection module during rotation. The design of the rotating disk enables the optical detection module to perform detections at different positions, increasing the detection coverage of the device. By adjusting the meshing of the gear and the sector-shaped turbine, the angle of the rotating disk can be precisely controlled, enabling the optical detection module to accurately align with the detection area of the fluorescence test card, thereby improving the detection accuracy.

[0017] Furthermore, a counterweight is installed at one end of the rotating disk symmetric to the optical detection module, which can balance the asymmetric weight distribution on the rotating disk due to the installation of the optical detection module, improving the smoothness and accuracy of rotation, and thus ensuring the stability and reliability of the detection results. A number of limiting holes are provided at one end of the rotating disk facing the light-transmitting plate.

[0018] Further, it further includes a positioning mechanism installed on the bearing seat for limiting, and the positioning mechanism includes a housing, an elastic member and a positioning bead. The housing is installed on the bearing seat and corresponds to the limiting hole. An elastic member and a positioning bead adapted to the limiting hole are installed in the housing. The positioning mechanism can effectively prevent the rotating disk from shifting due to vibration or external force during rotation, ensuring the stability and safety of the equipment operation. The positioning bead is locked in the limiting hole to ensure that the rotating disk remains in the correct position and will not shift due to external interference.

[0019] The adaptation of the positioning bead to the limiting hole enables the rotating disk to be accurately positioned to the predetermined position. The elastic member provides a certain elasticity, enabling the positioning bead to automatically pop into the limiting hole to achieve automatic alignment and locking.

[0020] Further, a plurality of slots distributed in a circular pattern are provided at the bottom of the slot plate, and a baffle capable of folding inward is provided at the open end of the slot. The baffle forms a protective wall at the slot opening end, which can prevent external debris or dust from entering the slot. This helps to extend the service life of the equipment and improve the reliability of the overall equipment.

[0021] Further, observation holes corresponding to the slots one by one are respectively provided above the slots. The optical detection module detects the fluorescence test card through the observation holes.

[0022] Further, a plurality of jacks are provided on the outer wall of the housing, and the jacks are arranged in one-to-one correspondence with the slots of the slot plate.

[0023] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: The driving member is vertically installed at the top of the housing and is connected to the sector-shaped turbine, and the sector-shaped turbine is engaged with the rotating mechanism; the driving mechanism drives the rotating mechanism through the driving member and the sector-shaped turbine, so that the optical detection module can rotate flexibly.

[0024] The positioning mechanism can effectively prevent the rotating disk from shifting due to vibration or external force during rotation, ensuring the stability and safety of the equipment operation. The positioning bead is locked in the limiting hole to ensure that the rotating disk remains in the correct position and will not shift due to external interference.

Detailed implementation manners

[0033] A housing 1 having a cylindrical structure.

[0034] A light-transmitting plate 2 located in the middle of the housing 1 and dividing the housing 1 into upper and lower parts.

[0035] An optical detection module 3 located in the upper part of the housing 1 for detecting the fluorescence test card.

[0036] A rotating mechanism 4 installed on the light-transmitting plate 2 as a carrier for carrying the optical detection module 3.

[0037] A driving mechanism 5 located at the top of the housing 1 for driving the rotating mechanism 4 to rotate.

[0038] A slot plate 6 located at the bottom of the housing 1 for accommodating the fluorescence test card.

[0039] A positioning mechanism 7 installed on the bearing seat 41 to play a limiting role.

[0040] Specifically, a plurality of jacks 11 are provided on the outer wall of the housing 1, and the jacks 11 are arranged in one-to-one correspondence with the slots 61 of the slot plate 6.

[0041] The specific light-transmitting plate 2 makes the overall structure compact and the functional areas clearly defined. The upper layer of the housing 1 is a sealed cavity. The optical detection module 3 rotates and scans in the sealed cavity to prevent the optical detection module 3 from communicating with the external environment during the detection process. Dust in the environment will enter and affect the detection accuracy of the optical detection module 3.

[0042] Specifically, the rotating mechanism 4 includes a bearing seat 41, a rotating shaft 42, a gear 43, and a rotating disk 44 for mounting the optical detection module 3. The bearing seat 41 is installed on the light-transmitting plate 2 and connected to the rotating shaft 42. The rotating shaft 42 is provided with a gear 43 meshing with the sector turbine 52 and a rotating disk 44 from top to bottom. The use of the bearing seat 41 ensures the smooth operation of the rotating shaft 42, while reducing friction and wear. This helps to improve the service life and reliability of the device, and ensures the stability of the optical detection module 3 during rotation. The design of the rotating disk 44 enables the optical detection module 3 to perform detections at different positions, increasing the detection coverage range of the device. By adjusting the meshing of the gear 43 and the sector turbine 52, the angle of the rotating disk 44 can be precisely controlled, enabling the optical detection module 3 to accurately align with the detection area of the fluorescence test card, thereby improving the detection accuracy.

[0043] More specifically, a counterweight 441 is installed at one end of the rotating disk 44 symmetric to the optical detection module 3. The counterweight 441 can balance the asymmetric weight distribution on the rotating disk 44 caused by the installation of the optical detection module 3, improving the smoothness and accuracy of rotation, and thus ensuring the stability and reliability of the detection results. The end of the rotating disk 44 facing the light-transmitting plate 2 is provided with a plurality of limiting holes 442.

[0044] Specifically, the driving mechanism 5 includes a driving member 51 and a sector turbine 52 adapted to the rotating mechanism 4. The driving member 51 is vertically installed at the top of the housing 1 and connected to the sector turbine 52. The sector turbine 52 meshes with the rotating mechanism 4. The driving mechanism 5 drives the rotating mechanism 4 through the driving member 51 and the sector turbine 52, enabling the optical detection module 3 to rotate flexibly.

[0045] Specifically, the bottom of the slot plate 6 is provided with a plurality of slots 61 distributed in a circular pattern. The open end of the slot 61 is provided with a baffle 62 that can be folded inward. The baffle 62 forms a protective wall at the opening end of the slot 61, which can prevent external debris or dust from entering the slot 61. This helps to extend the service life of the device and improve the reliability of the overall device. Above each slot 61, there is an observation hole 63 corresponding to it one by one. The optical detection module 3 detects the fluorescence test card through the observation hole 63.

[0046] The specific positioning mechanism 7 includes a housing 71, an elastic member 72 and a positioning bead 73. The housing 71 is installed on the bearing seat 41 and corresponds to the limiting hole 442. An elastic member 72 and a positioning bead 73 adapted to the limiting hole 442 are installed in the housing 71. The positioning mechanism 7 can effectively prevent the rotating disk 44 from shifting due to vibration or external force during rotation, ensuring the stability and safety of the equipment operation. The adaptation of the positioning bead 73 to the limiting hole 442 enables the rotating disk 44 to be accurately positioned at a predetermined position. The elastic member 72 provides a certain elastic force, enabling the positioning bead 73 to automatically pop into the limiting hole 442 to achieve automatic alignment and locking.

[0047] The working principle of the present utility model: A plurality of fluorescence test cards are respectively inserted into the respective slots 61 of the slot plate 66. After the fluorescence test cards are loaded, the driving member 51 drives the sector turbine 52 to rotate, thereby driving the optical detection module 3 installed on the rotating disk 44 to rotate. The optical detection module 3 sequentially passes through the light-transmitting plate 2 and the observation hole 63 to detect the fluorescence test cards in the slots 61 one by one. The present utility model drives the rotating disk 44 to rotate unidirectionally through the sector turbine 52. Each time the sector turbine 52 rotates one circle, the optical detection module 3 moves forward to the next slot 61, and the positioning mechanism 7 can effectively prevent the rotating disk 44 from shifting due to vibration or external force during rotation. Thus, the one-by-one detection of a plurality of fluorescence test cards can be realized. The optical detection module 3 rotates and scans in a sealed clamping cavity, avoiding the optical detection module 3 being connected to the external environment during the detection process, and dust in the environment will affect the detection accuracy of the optical detection module 3 after entering.

[0048] The above is only used to illustrate the technical solution of the present utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present utility model, as long as they do not depart from the spirit and scope of the technical solution of the present utility model, shall be covered by the scope of the claims of the present utility model.
