Description

Technical Field

[0001] The present application relates to the technical field of detection instruments, and in particular to an automatic immunofluorescence detector. Background Art

[0002] Immunofluorescence technique, also known as fluorescent antibody technique, is one of the earliest developed labeling immunotechniques. It is a technique established on the basis of immunology, biochemistry and microscopy. Immunofluorescence detection technology can be widely used in the detection site for quantitative and qualitative detection, and is an important development direction in the field of POCT (point-of-care testing) in the future. In addition, immunofluorescence detection technology can be widely used in multiple fields such as food or drug detection and biochemical detection in hospitals. In the prior art, immunofluorescence analyzers mainly include semi-automatic single-channel instruments and linear array multi-channel instruments. Semi-automatic single-channel instruments require a long time for manual operation and have low efficiency. On the basis of semi-automatic single-channel instruments, linear array multi-channel instruments realize multi-channel by arranging the detection channel array, which easily leads to a large volume together, and there is a problem that the number of channels and the appropriate volume of the instrument cannot be achieved at the same time. Both have certain disadvantages.

[0003] In summary, since the immunofluorescence analyzers in the prior art have certain drawbacks, how to propose a better immunofluorescence detector that can achieve automatic detection and large-scale detection is an urgent problem to be solved in this field. Summary of the invention

[0061] In order to make the technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0062] As Figures 1 to 11 shown, the present invention provides an immunofluorescence detector, including: a bottom plate 13, a housing 7, a lower computer 9, a first bracket 39, a second bracket, a card inlet module 15, a card feeding module 14, a rotation module 10, and a detection and card ejection module 11;

[0063] The housing 7 is arranged above the bottom plate 13, and the lower computer 9, the first bracket 39, the second bracket, the card inlet module 15, the card feeding module 14, the rotation module 10, and the detection and card ejection module 11 are all arranged inside the housing 7; a host computer 1 and a card slot 2 are arranged on the housing 7;

[0064] The lower computer 9 is fixed on the bottom plate 13, and is used for transmitting data signals to and from the host computer 1, and sending control signals to the card inlet module 15, the card feeding module 14, the rotation module 10, or the detection and card ejection module 11;

[0065] The rotation module 10 includes a turntable 46 and a first driving device. The turntable 46 is arranged at the top of the first driving device, and the first driving device is fixed on the bottom plate 13; a plurality of card bins 68 are arranged on the edge of the turntable 46;

[0066] The card feeding module 15 and the card delivering module 14 are fixed on the bottom plate 13 through the first bracket 39, and are located on one side of the rotating module 10. Among them, the card delivering module 14 is arranged above the card feeding module 15, and the top end of the card feeding module 15 is at the same height as the top end of the turntable 46. The card feeding module 15 is used to receive the test card from the card insertion slot 2, and the card delivering module is used to convey the test card on the card feeding module 15 to the turntable 46;

[0067] The detection and card ejection module 11 is fixed on the bottom plate 13 through the second bracket, and is located on the other side of the rotating module 10. Among them, the bottom end of the detection and card ejection module 11 is at the same height as the card bin 68. The detection and card ejection module 11 is used to perform fluorescence detection on the test card, output detection data, and eject the test card.

[0068] Through the above settings, the test card that needs to be subjected to immunofluorescence detection can be inserted from the card insertion slot 2 on the outer shell into the card feeding module 15. Since the card delivering module 14 is located above the card feeding module 15, the card delivering module 14 can send the test card on the card feeding module 15 to a certain card bin 68 on the turntable 46 at the top end of the rotating module 10. Driven by the first driving device, the turntable is driven to rotate and the card bin with the test card is rotated to directly below the detection and card ejection module 11. The detection result can be obtained through the detection function of the detection and card ejection module 11, and finally the test card is ejected from the detection and card ejection module through the card ejection function of the detection and card ejection module 11.

[0069] In the technical solution of the present invention, various implementation methods can be used to implement the above-mentioned immunofluorescence detector. Hereinafter, one implementation manner will be taken as an example to introduce the technical solution of the present invention in detail.

[0070] For example, preferably, in a specific embodiment of the present invention, as Figure 1 and 2 shown, the immunofluorescence detector may further include a waste card box 12, and the waste card box 12 is arranged below the detection and card ejection module 11.

[0071] Preferably, the outer surface 8 of the waste card box 12 and the outer shell 7 can be magnetically attracted and connected, so that it is convenient to take out the waste card box and the outer surface of the waste card box can be fitted and connected with the outer surface of the outer shell.

[0072] By providing the waste card box, when the test card after the detection is completed is ejected through the card ejection function of the detection and card ejection module 11, the test card can fall into the waste card box, which is convenient for recycling the test card that has completed the detection. When the waste card box is full of test cards, the waste card box can be taken out, cleaned and then reinstalled.

[0073] In addition, as an example, in a preferred specific embodiment of the present invention, as Figure 1As shown, the host computer 1 is arranged on the outer shell 7. The host computer 1 includes a display screen, a central processor and a memory. The host computer is used for human-computer interaction, and the display screen facilitates the operator to perform visual control on the detection process.

[0074] The operator can input control instructions to the host computer 1 through the display screen, and the host computer then sends data signals to the slave computer 9. The slave computer 9 can send signals to the card feeding module 15, the card sending module 14, the rotating module 10 or the detection and card ejection module 11, so as to control the mechanical actions of each module. The slave computer 9 can also send data signals to the host computer 1 and display them on the display screen of the host computer, so as to facilitate the operator to understand the working state of the detector.

[0075] Preferably, the slave computer can be a hardware circuit board with a single-chip microcomputer as the control chip. This hardware circuit board has functions of signal transmission, motor control, fluorescence collection and external interruption (for example, it can detect the jump of the level signals generated by the photoelectric switch and the touch switch).

[0076] In addition, as an example, in a preferred specific embodiment of the present invention, as Figure 1 shown, the outer shell 7 may further include: an infrared scanning bin 3 and a thermal printer 4; wherein,

[0077] The infrared scanning bin 3 is used to read the bar code information corresponding to the detection card information (for example, the bar code information on the bill or voucher), and transmit the information of the detection card to the central processor of the host computer 1. Through processing and analysis, the detection data of the detection card stored in the memory can be displayed on the display screen through the display of the information of the read bar code.

[0078] The thermal printer 4 is used to receive the data of the detection result sent by the host computer and print the detection result.

[0079] Preferably, the outer shell 7 may further include: a power jack 5 and a power switch 6; the power jack 5 is used to connect the power supply; the power switch 6 is used to control the closing of the power supply.

[0080] For another example, preferably, in a specific embodiment of the present invention, as Figure 3 shown, the first driving device further includes: a rotating device, a positioning module and a turntable base 51; the top end of the turntable base 51 is fixedly connected to the turntable 46, and the bottom end of the turntable base 51 is fixedly connected to the rotating device; the positioning module is located outside the rotating device and is arranged below the turntable 46.

[0081] As an example, preferably, the rotating device may include: a driving motor bracket 41, a driving motor 42, a driving wheel 43, a belt 44, a driven wheel 47, a bearing block bracket 50, a bearing 49, and a driving shaft 48;

[0082] The driving motor bracket 41 is fixed on the bottom plate 13, and the driving motor 42 is fixed on the driving motor bracket 41;

[0083] The driving wheel 43 is fixed on the output shaft of the driving motor 42;

[0084] The bearing block bracket 50 is fixed on the bottom plate 13 inside the driving motor bracket 41, and the bearing 49 is fixed at the top of the bearing block bracket 50;

[0085] The top end of the driving shaft 48 is fixedly connected to the bottom end of the turntable base 51, and the bottom end of the driving shaft 48 is fixedly connected to the top end of the bearing 49;

[0086] The driven wheel 47 is sleeved and fixed on the driving shaft 48. The driven wheel 47 and the driving wheel 43 are at the same horizontal height and are connected by a belt 44.

[0087] Since the driven wheel and the driving wheel are at the same horizontal height, when the driving motor rotates, it drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate through the belt, thereby realizing the rotation of the entire turntable.

[0088] Preferably, the driving shaft 48 can be fixed on the turntable base 51 by screws and keyway key pins in cooperation.

[0089] Preferably, the bearing 49, the driven wheel 47, and the driving shaft 48 are coaxial.

[0090] As an example, preferably, the positioning module includes: a turntable adapter 79, a plurality of gratings 65, a photoelectric switch bracket 67, and a photoelectric switch 66;

[0091] The top surface of the turntable adapter 79 is fixedly connected to the bottom end of the turntable 46, and the plurality of gratings 65 are evenly distributed and fixed at the bottom end of the turntable adapter 79;

[0092] The photoelectric switch bracket 67 is fixed on the bottom plate 13, and the photoelectric switch 66 is fixed on the photoelectric switch bracket 67. The height of the photoelectric switch 66 from the bottom plate is the same as the height of the grating 65 from the bottom plate. The photoelectric switch 66 is used to cooperate with the grating 65 to generate a signal and send the signal to the lower computer.

[0093] Preferably, 4 gratings 65 can be evenly fixed at the bottom end of the turntable adapter 79.

[0094] Preferably, the turntable adapter 79 can be annular and fixed to the outside of the turntable base 51.

[0095] Preferably, the turntable 46 and the turntable adapter 79 can be fixedly connected by screws and pins.

[0096] With the above settings, the grating 65 and the photoelectric switch 66 cooperate to work, and the precise positioning of the turntable 46 can be realized. When the turntable rotates, it drives the grating to rotate. When the slit on the grating passes through the photoelectric switch, a level jump signal will be generated. The photoelectric switch sends the level jump signal to the lower computer. The single-chip microcomputer on the lower computer has an external interrupt function. After detecting the level jump signal, it issues a stop command to the turntable, thereby realizing the precise positioning of the turntable. Further, a certain card bin on the turntable can be aligned with the card slot 27 on the card feeding module or the detection station 77 on the detection and card ejection module.

[0097] In addition, preferably, in the specific embodiment of the present invention, as Figure 4 shown, a plurality of card bins 68 are evenly distributed on the edge of the turntable 46. On the left and right sides of each card bin 68, fan-shaped convex blocks are provided. On the left and right sides of each fan-shaped convex block, touch elastic pieces 69 are respectively provided. Above the touch elastic piece 69, a cover plate 45 is provided. The width of the cover plate 45 is greater than the width of the fan-shaped convex block.

[0098] Preferably, a spring device is provided on the touch elastic piece 69, so that it can be suitable for detection cards of different widths. The touch elastic pieces 69 on two adjacent fan-shaped convex blocks can clamp the detection card to limit the detection card.

[0099] Since the width of the card bin 68 is greater than the width of the detection card, touch elastic pieces 69 are provided on the fan-shaped convex blocks on the left and right sides of the card bin 68. The touch elastic pieces 69 on two adjacent fan-shaped convex blocks can play a role in limiting the detection card on the left and right. In addition, since a cover plate 45 is installed above the touch elastic piece on each fan-shaped convex block, and the width of the cover plate 45 is greater than the width of the fan-shaped convex block, under the action of the card feeding module, the detection card can be inserted under the edges of two adjacent cover plates in the card bin (for example, two adjacent cover plates 45 respectively cover 25% of both sides of the detection card), so that the cover plates on two adjacent fan-shaped convex blocks can play a role in limiting the detection card on the upper and lower sides.

[0100] Preferably, 20 card bins 68 can be provided on the edge of the turntable 46.

[0101] In addition, preferably, in the specific embodiment of the present invention, as Figure 5 shown, the card feeding module 15 includes: a card feeding motion platform assembly 62 and a card slot 27;

[0102] The movement platform component 62 includes: a card feeding motor 18, a card feeding module bottom plate 23, a right support frame 19, a left support frame 25, two first touch switches 20, a second touch switch 28, two card feeding guide shafts 16, and a card feeding movement platform 21;

[0103] The right support frame 19 and the left support frame 25 are respectively and vertically fixed on the left and right side edges of the card feeding module bottom plate 23;

[0104] The card feeding motor 18 is fixed on the right side of the right support frame 19, and the output shaft of the card feeding motor 18 passes through the right support frame 19; the two card feeding guide shafts 16 are respectively arranged on both sides of the output shaft of the card feeding motor 18, and both ends of the two card feeding guide shafts 16 are fixedly connected to the right support frame 19 and the left support frame 25;

[0105] The card feeding movement platform 21 is arranged between the right support frame 19 and the left support frame 25, and is sleeved on the output shaft of the card feeding motor 18 and the two card feeding guide shafts 16, and can slide along the extending direction of the two card feeding guide shafts 16;

[0106] The two first touch switches 20 are respectively arranged on the card feeding module bottom plate 23 at the lower parts of the right support frame 19 and the left support frame 25, and the first touch switches 20 are used to control the card feeding movement platform 21 to stop moving;

[0107] The card slot 27 is fixed at the top end of the card feeding movement platform 21, and a second touch switch 28 is arranged at the rear end of the card slot 27, and the second touch switch 28 is used to detect whether the detection card is inserted in place in the card slot 27.

[0108] Preferably, a first ball screw pair 17 and two first linear bearings 24 are arranged on the card feeding movement platform 21, the first ball screw pair 17 is arranged at the middle position of the card feeding movement platform 21 and is sleeved on the output shaft of the card feeding motor 18; the two first linear bearings 24 are respectively arranged on both sides of the first ball screw pair 17 and are respectively sleeved on the two card feeding guide shafts.

[0109] Preferably, the two first linear bearings 24 are fixedly connected to the card feeding movement platform 21 through the threaded holes 22 on the card feeding movement platform 21.

[0110] Preferably, the card slot 27 and the card insertion opening 2 on the housing are at the same horizontal height and correspond to each other.

[0111] Preferably, the card slot 27 can be used to insert the detection card 26; the front half part of the card slot 27 can be an open structure to facilitate the card slot to enter and exit the housing, and the rear half part of the card slot 27 can be a semi-surrounding structure to facilitate fixing the detection card.

[0112] Preferably, the card insertion slot 2 can be a spring door structure. In the normal state, the spring door is in a closed state to ensure a darkroom environment inside the machine. When the card slot 27 moves towards the outside of the housing, the card slot pushes the spring door to move counterclockwise, and the spring door opens. The front half of the card slot is exposed outside the housing, so that the inspection personnel can conveniently insert the inspection card.

[0113] If the second touch switch 28 senses that the inspection card has been inserted, the card feeding motor 18 rotates in the reverse direction, and the card feeding moving platform 21 drives the card slot 27 to complete the card feeding operation. If the second touch switch 28 does not sense the inspection card, the card feeding operation will not be performed.

[0114] The moving platform assembly 62 has a simple structure and low cost. The left support frame 25, the right support frame 19, and the card feeding module bottom plate 23 play a load-bearing role. Two card feeding guide shafts 16 are fixed between the left support frame 25 and the right support frame 19 by screws, playing a role in guiding and supporting the card feeding moving platform 21. The card feeding motor 18 and the card feeding moving platform 21 are fixed through the first ball screw pair 17. The card feeding moving platform 21 can be driven by the card feeding motor 18 and can perform precise and rapid translational motion on the card feeding guide shaft in cooperation with the touch switch, thereby completing the card feeding action.

[0115] When card feeding is required, driven by the card feeding motor 18, the card feeding moving platform 21 can move towards the left support frame 25, thus driving the card slot 27 to move towards the card insertion slot 2. When the card feeding moving platform 21 touches the first touch switch 20 at the lower part of the left support frame 25, the card feeding moving platform 21 stops. At this time, the front half of the card slot 27 extends out of the card insertion slot 2, and the operator can insert the inspection card into the card slot 27. When the inspection card touches the second touch switch 28 on the card slot 27, it indicates that the inspection card is inserted in place. At this time, under the reverse driving of the card feeding motor 18, the card feeding moving platform 21 starts to move towards the right support frame 19, driving the card slot 27 to move towards the turntable. When the card feeding moving platform 21 touches the first touch switch 20 at the lower part of the right support frame 19, the card feeding moving platform 21 stops moving. At this time, the rear end of the card slot 27 is docked with a preset card bin on the turntable, completing the card feeding action.

[0116] In addition, as an example, in a preferred specific embodiment of the present invention, as Figure 6 and Figure 7 shown, the card feeding module 14 includes: a card feeding moving platform assembly and a first card scraping device;

[0117] The card feeding moving platform assembly includes: a card feeding motor 35, a card feeding module bottom plate 37, two support plates 34, two card feeding guide shafts, two third touch switches 36, and a card feeding moving platform 30;

[0118] The two support plates 34 are respectively and vertically fixed below both sides of the bottom plate 37 of the card feeding module;

[0119] The card feeding motor 35 is arranged outside one of the support plates 34, and the output shaft of the card feeding motor 35 passes through the support plate 34 close to the card feeding motor 35;

[0120] Two card feeding guide shafts are respectively arranged on both sides of the output shaft of the card feeding motor 35, and both ends of the two card feeding guide shafts are fixedly connected to the two support plates 34;

[0121] The card feeding moving platform 30 is arranged between the two support plates 34, and is sleeved on the output shaft of the card feeding motor 35 and the two card feeding guide shafts, and can slide along the extending direction of the two card feeding guide shafts;

[0122] The two third touch switches 36 are respectively arranged on the bottom plate 37 of the card feeding module at the upper parts of the two support plates 34, and are used for controlling the card feeding moving platform 30 to stop moving;

[0123] The first card scraping device includes: a fixed table 31 and a card feeding scraping plate 32; the fixed table 31 is fixed at the bottom end of the card feeding moving platform 30, and the card feeding scraping plate 32 is arranged at the bottom end of the fixed table 31.

[0124] Preferably, a second ball screw pair 29 and two second linear bearings are arranged on the card feeding moving platform 30, the second ball screw pair 29 is arranged at the middle position of the card feeding moving platform 30 and is sleeved on the output shaft of the card feeding motor 35; the two second linear bearings are respectively arranged on both sides of the second ball screw pair 29 and are sleeved on the two card feeding guide shafts.

[0125] Preferably, the two second linear bearings can be fixedly connected to the card feeding moving platform 30 through the tooth holes on the card feeding moving platform 30.

[0126] Preferably, the fixed table 31 and the card feeding scraping plate 32 can be connected through a first connecting shaft 33, and the card feeding scraping plate can only rotate unidirectionally.

[0127] Preferably, the card feeding scraping plate 32 can correspond to the card slot 27 in the card feeding module 15.

[0128] Through the above settings, under the driving action of the card feeding motor 35, the card feeding moving platform 30 can drive the fixed table 31 and the card feeding scraping plate 32 to perform translational movement, and the card feeding scraping plate 32 can convey the detection card in the card slot 27 of the card feeding module 15 to a preset card bin 68.

[0129] Since the card feeding scraping plate is fixed in the middle of the fixed table through the first connecting shaft, and the rear baffle of the fixed table can limit the rotation of the card feeding scraping plate along the direction of the rear baffle of the fixed table (such as Figure 8In [the figure], the card feeding squeegee can only rotate counterclockwise and cannot rotate clockwise, so the card feeding squeegee can only move in one direction.

[0130] Since the card feeding squeegee is a component that moves in one direction, and the front half of the card slot 27 is an open structure while the rear half is a semi-surrounding structure, during the process of the card feeding module moving outward and extending out of the card insertion slot, since there is no test card in the card slot at this time, even if the card feeding squeegee is placed in the slot opening in the middle of the card slot but does not contact the card slot, it will not affect the outward movement of the card feeding module; during the process of inserting the test card, under the push of the test card, the card feeding squeegee can move in the movement direction of the test card (that is Figure 8 in [the figure], the card feeding squeegee can rotate counterclockwise), in addition, when the card slot moves towards the direction close to the turntable, since the card feeding squeegee can move along the movement direction of the card slot (that is Figure 8 in [the figure], the card feeding squeegee can rotate counterclockwise), therefore, during the process of inserting the test card and the card slot moving towards the direction close to the turntable, the card feeding squeegee will not affect the movement of the card feeding module either. Until when the card feeding squeegee is at the outer end of the card slot (that is Figure 8 the left end of the card slot in [the figure]) and the lower edge of the card feeding squeegee is lower than the upper surface of the test card, since the card feeding squeegee 32 cannot rotate along the direction of the rear baffle of the fixed table (that is Figure 8 in [the figure], the card feeding squeegee cannot rotate clockwise), so when card feeding is required, the card feeding movement platform 30 drives the fixed table 31 to move towards the card bin direction, and the card feeding squeegee pushes the test card to move towards the direction close to the turntable, so that the test card is sent into the card bin.

[0131] In addition, as an example, in a preferred specific embodiment of the present invention, as Figure 7 shown, the first bracket 39 includes two longitudinal beams, a cross beam 38 and a top beam 40; the two longitudinal beams are fixed on the bottom plate 13, and the two ends of the cross beam 38 are respectively fixed at the middle positions of the two longitudinal beams; the two ends of the top beam 40 are respectively fixed at the tops of the two longitudinal beams; the bottom end of the card feeding module bottom plate 23 of the card feeding module 15 is fixed on the cross beam 38; the top end of the card feeding module bottom plate 37 of the card feeding module 14 is fixed on the top beam 40.

[0132] In addition, as an example, in a preferred specific embodiment of the present invention, as Figures 9 to 11 shown, the detection and card ejection module 11 includes: a second driving device, a detection device and a card ejection device;

[0133] The second driving device includes: a detection motor 61, a support structure 75, a detection movement platform 73 and a detection guide shaft 76; the detection motor 61 is fixed on the outside of the support structure 75, and the detection movement platform 73 is movably arranged on the inside of the support structure 75 through the output shaft of the detection motor 61 and the detection guide shaft 76;

[0134] The detection device includes: two upper and lower adjustment plates 58, a left and right adjustment plate 60, a fixing plate 57, an optical module 56, and a detection station 77; the left and right adjustment plate 60 is fixed to the bottom end of the detection moving platform 73; the fixing plate 57 is a semi-surrounding structure, including: a first side plate 571 and a second side plate 572; the top end of the fixing plate 57 is fixedly connected to the bottom end of the left and right adjustment plate 60; the inner sides of the two upper and lower adjustment plates 58 are respectively fixed to both sides of the optical module 56, and the outer sides of the two upper and lower adjustment plates 58 are respectively connected to the inner sides of the first side plate 571 and the second side plate 572; the detection station 77 is fixed on the second bracket and corresponds to the height of the turntable 46;

[0135] The card ejection device includes: a card ejection adapter 70, a connecting platform 71, and a card ejection scraper 59; the card ejection adapter 70 is fixed on the optical module 56, the connecting platform 71 is fixed to the lower part of the card ejection adapter 70, and a card ejection scraper 59 is fixed to the lower part of the connecting platform 71.

[0136] Preferably, the connecting platform 71 and the card ejection scraper 59 can be connected by a second connecting shaft 72.

[0137] Preferably, fourth touch switches 80 are respectively arranged at both ends of the support structure 75 for controlling the detection moving platform 73 to stop moving.

[0138] Preferably, the top end between the left and right adjustment plate 60 and the fixing plate 57 can be fixedly connected by a notch and a screw, so that the horizontal position of the fixing plate and the optical module arranged inside it can be adjusted by adjusting the relative positions of the screw and the notch; the two upper and lower adjustment plates and the first side plate 571 and the second side plate 572 can be fixedly connected by a notch and a screw, so that the two upper and lower adjustment plates 58 are respectively arranged between the two side plates of the fixing plate and the optical module, and the vertical position of the upper and lower adjustment plates and the optical module fixedly connected thereto can be adjusted by adjusting the relative positions of the screw and the notch.

[0139] Through the above settings, during the assembly process before the detector leaves the factory, the position of the optical module 56 can be finely adjusted by the left and right adjustment plate 60 and the upper and lower adjustment plates 58 to ensure the precise installation of the optical module, thereby ensuring the accuracy of the laser irradiation position and the excitation light reflection focal length during fluorescence detection, and further ensuring the quality of the detector when it leaves the factory.

[0140] Since the connecting platform 71 and the card ejection scraper 59 can be connected by a second connecting shaft 72, the rear baffle of the connecting platform can prevent the card ejection scraper from rotating along the direction of the rear baffle of the connecting platform. Therefore, the card ejection scraper 59 can only move in one direction (i.e., Figure 11The card ejection squeegee in it can only rotate counterclockwise and cannot rotate clockwise). Therefore, under the driving action of the detection motor 61, the detection moving platform 73 drives the optical module 56 and the card ejection squeegee 59 to move first in the direction close to the turntable 46. At this time, since the card ejection squeegee can rotate counterclockwise on the upper surface of the detection card, this movement process will not be affected until the lower edge of the card ejection squeegee is inside the detection card (i.e., Figure 11 the left side in it), and when the lower edge of the card ejection squeegee is lower than the upper surface of the detection card, the detection motor reverses, and the detection moving platform 73 drives the optical module 56 and the card ejection squeegee 59 to move in the direction close to the detection station 77. At this time, since the card ejection squeegee cannot rotate clockwise, the card ejection squeegee will push the detection card in the direction close to the detection station 77 until the detection card is pushed onto the detection station 77; then, through the driving action of the detection motor, the optical module 56 is driven to move horizontally. When the optical module is above the detection station and aligned with the detection card on the detection station, detection is performed; after the detection is completed, the detection motor 61 can continue to drive the card ejection squeegee in the direction close to the detection station, and the card ejection squeegee 59 can push the detection card on the detection station 77 backward from the detection station, so that the detection card falls into the waste card box below, and the detection and card ejection are completed.

[0141] In addition, as an example, in a preferred specific embodiment of the present invention, as Figure 10 shown, the second bracket includes: a first pair of longitudinal beams 52, a second pair of longitudinal beams 54, an intermediate beam 53, a first top beam 74, and a second top beam 55; the first pair of longitudinal beams 52 is arranged in front of the second pair of longitudinal beams 54; the intermediate beam 53 is fixed at the middle position of the first pair of longitudinal beams 52, the first top beam 74 is fixed at the top of the first pair of longitudinal beams 52, and the second top beam 55 is fixed at the top of the second pair of longitudinal beams 54.

[0142] Preferably, the top end of the support structure 75 is fixed on the first top beam 74 and the second top beam 55.

[0143] Preferably, the detection station 77 is of an encircling structure and is fixed on the intermediate beam 53. The detection station 77 is separately fixed on the intermediate beam 53, which can ensure that the height of all detection cards from the optical module is the same during detection, helping to improve the performance index of the instrument.

[0144] Preferably, a touch switch is installed on the detection station 77, and the touch switch can identify whether there is a detection card on the detection station. The length of the detection station can be less than the length of the detection card, which helps to shorten the stroke of the detection motor when ejecting the card.

[0145] Additionally, as an example, in a preferred specific embodiment of the present invention, a slit and an optical system are provided in the optical module 56 for generating an excitation light strip, and a fluorescence acquisition circuit board is provided for acquiring and transmitting fluorescence data. The fluorescence acquisition circuit board can transmit the data to a lower computer, and the lower computer then transmits the data to an upper computer. The central processor of the upper computer processes and judges the fluorescence data to obtain a final detection result, and can store the detection data through the memory of the upper computer.

[0146] Preferably, a protrusion with a spring is provided on each touch switch in this application. When an object touches the protrusion, the protrusion can be pressed down, and when the object leaves, the protrusion bounces back. When the protrusion is pressed down or bounces back, a level jump signal is generated, and the single-chip microcomputer on the lower computer can detect this level jump signal, thereby issuing corresponding stop or operation instructions to each module.

[0147] In a specific operation embodiment of the present invention, first, the machine is reset. The driving motor 42 drives the turntable 46 to rotate, and initial positioning is achieved in cooperation with the optoelectronic switch 66 and the grating 65, so that a preset magazine and a card slot 27 on the turntable are aligned (for example, the magazines on the turntable can be numbered from 1 to 20. After the detector is reset, the No. 1 magazine is aligned with the card slot 27, and the cards can also be placed in sequence starting from the No. 1 magazine). The motors in the card feeding module 15, the card delivering module 14, and the detection and card ejecting module 11 move simultaneously for resetting to ensure the safety of the detector operation.

[0148] When detection is required, the card feeding motor 18 moves towards the machine housing 7. The card slot 27 pushes the card feeding spring door to rotate counterclockwise, and the card slot 27 extends out from the card insertion opening. After the operator inserts the detection card onto the card slot 27, the second touch switch 28 senses that the detection card has been inserted in place, and the card feeding motor 18 rotates in the reverse direction. The card feeding movement platform 21 drives the card slot 27 to complete the card feeding operation. After the card feeding is completed, the card sending motor 35 rotates forward, and the card sending movement platform 30 drives the fixed table 31 towards the turntable 46. The card sending squeegee 32 pushes the detection card 26 into the preset position in the card bin 68. The machine automatically times. When the incubation time of the detection card is reached, the main motor 42 performs a step movement to rotate the pre-detection card bin with the detection card to the position of the detection and card ejection module 11. The detection motor 61 moves towards the detection station 77 (for example, the detection motor rotates forward at this time), pushes the detection card to be tested into the detection station 77, and then drives the optical module to move (for example, the detection motor rotates in the reverse direction at this time) while completing the fluorescence detection work. Then the detection motor 61 drives the card ejection squeegee 59 to move (for example, the detection motor rotates forward at this time), ejects the detection card from the detection station, and the detection card after the detection falls into the waste card box 12 to complete the card ejection operation. When the waste card box is full, the operator pulls out the waste card bin 12, cleans the waste card box 12 and then puts the waste card box 12 back into the machine. The above process is the detection process of one card. In the actual detection process, there will be a large number of detection cards to be detected. The upper computer of the present invention will automatically process the detection work of the detection cards in multiple card bins. There is a fluorescence acquisition circuit board in the optical module 56, which is used to collect and transmit fluorescence data. The fluorescence acquisition circuit board transmits the data to the lower computer, and the lower computer then transmits the data to the upper computer. The upper computer processes and judges the fluorescence data, and finally combines the detection situation to obtain the detection result.

[0149] In summary, in the technical solution of the present invention, due to the ingenious structural design of the detector, the entire detection process can be completed automatically. After the operator inserts the detection card into the card insertion opening, he only needs to wait to view the detection result. The instrument can complete the entire process of automatic card feeding, automatic card sending, automatic incubation timing, automatic detection, and automatic card ejection by itself. At the same time, the detection result can be automatically uploaded to the upper computer system, can be displayed through the display screen, and also supports thermal printing. In addition, since there are multiple card bins inside the detector, it is conducive to large-scale and multi-project detection, which can greatly reduce the labor intensity of personnel and improve the detection performance.

[0150] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the scope of protection of the present invention.
