DETAILED DESCRIPTION

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0043] See also Figure 1 , Figure 1 The structural schematic diagram of the cartridge in-and-out warehouse mechanism of one embodiment of the present invention is shown. One embodiment of the present invention provides a cartridge in-and-out warehouse mechanism, and the cartridge in-and-out warehouse mechanism includes: a mounting plate 10, a cartridge tray 20, a first push-pull mechanism 30, and a second push-pull mechanism 40. The mounting plate 10 is provided with a support structure 11, and a first window 12 is provided. The cartridge tray 20 is movably arranged on the support structure 11, and the cartridge tray 20 is used to place a reagent cartridge 50. The first push-pull mechanism 30 is installed on the mounting plate 10, and the first push-pull mechanism 30 is used to drive the cartridge tray 20 to move to the in-warehouse position or the out-warehouse position. When the cartridge tray 20 moves to the in-warehouse position, the reagent cartridge 50 placed on the cartridge tray 20 is exposed to the first window 12. The second push-pull mechanism 40 is installed on the cartridge tray 20, and the second push-pull mechanism 40 is used to drive the chip 51 to move outward or inward into the reagent cartridge 50.

[0044] In the above-mentioned cartridge in-and-out warehouse mechanism, when the first push-pull mechanism 30 drives the cartridge tray 20 to move to the warehouse entry position, and the second push-pull mechanism 40 drives the chip 51 to move outward, the reagent cartridge 50 and the chip 51 are exposed in the first window 12, and the fluorescence intensity detection operation is performed on the liquid in the cartridge tray 20, and the cartridge tray 20 is subjected to the liquid aspiration or liquid replenishment operation, and the detection device above the cartridge tray 20 can perform the detection operation on the chip 51 through the first window 12. After the relevant detection operation is completed, the chip 51 is driven to move inward into the reagent cartridge 50 by the second push-pull mechanism 40, and the cartridge tray 20 is moved to the warehouse exit position by the first push-pull mechanism 30. In this way, during the detection operation, the detection device above the cartridge tray 20 can avoid mutual interference with the mounting plate 10, thereby ensuring that the relevant detection operation is carried out smoothly, the working efficiency is high, and the overall structure is relatively simple.

[0045] Furthermore, the support structure 11 is arranged on the bottom surface of the mounting plate 10, and the cartridge tray 20 is located below the mounting plate 10. The cartridge tray 20 is movably arranged below the mounting plate 10, so that the lower part of the cartridge tray 20 is suspended, and is not movably arranged above the mounting base plate as in the conventional technology. In this way, the detection device above the cartridge tray 20 can avoid mutual interference with the mounting plate 10 during the detection operation, thereby ensuring that the related detection operation is carried out smoothly, the working efficiency is high, and the overall structure is relatively simple.

[0046] Specifically, as an example, the size of the first window 12 is not limited here and can be set according to actual conditions. The design size of the first window 12 can be satisfied as long as it can meet the requirements that when the reagent cartridge 50 moves to the storage position and the chip 51 is removed from the reagent cartridge 50, the reagent cartridge 50 and the chip 51 can be directly tested in the first window 12. In this way, it is convenient for the detection device above the cartridge tray 20 to perform the test operation on the chip 51 and the reagent cartridge 50 through the first window 12, and it can avoid mutual interference with the mounting plate 10, thereby ensuring that the related test operations are carried out smoothly and the working efficiency is high.

[0047] See also Figures 1 to 3 , Figure 2 Shows Figure 1 A structural diagram from a perspective when the second push-pull mechanism 40 is hidden, Figure 3 Shows Figure 1 Another perspective structural diagram when the second push-pull mechanism 40 is hidden in the middle. Further, a second window 21 is provided on the cartridge tray 20. When the chip 51 of the reagent cartridge 50 on the cartridge tray 20 is pulled outward, the chip 51 is located in the second window 21. The second window 21 is used to expose the chip 51 of the reagent cartridge 50. In this way, the reagent cartridge 50 is placed on the cartridge tray 20, and the cartridge tray 20 drives the reagent cartridge 50 into the warehouse. When the chip 51 is driven outward from the reagent cartridge 50 by the second push-pull mechanism 40, the chip 51 will move to the second window 21 accordingly, and the second window 21 exposes the chip 51, so that the detection device located below the cartridge tray 20 can be used in the second window 21 to perform detection operations on the chip 51. Furthermore, the upper and lower surfaces of the chip 51 are not blocked, which facilitates the detection instrument to perform various treatments on the chip 51.

[0048] See also Figures 1 to 3Furthermore, the cartridge tray 20 is provided with a first opening 22, and the first opening 22 is used to expose the reagent cartridge 50 and perform pre-processing operations on the reagent cartridge 50. That is, not only can the chip 51 be detected, but also the cartridge pre-processing device below the cartridge tray 20 can directly perform pre-processing operations on the reagent cartridge 50 on the cartridge tray 20 through the first opening 22; when the pre-processing operation of the reagent cartridge 50 is completed, the cartridge tray 20 is moved to the exit position by the first push-pull mechanism 30. In this way, during the pre-processing operation of the cartridge pre-processing device, it can avoid mutual interference with the installation base plate, and there is enough space for pre-processing operations, thereby ensuring that the pre-processing operation is carried out smoothly, and the overall structure is relatively simplified.

[0049] See also Figures 1 to 3 Furthermore, the cartridge tray 20 is provided with a second opening 23, and the second opening 23 is used to expose the identification of the reagent cartridge 50. The identification is specifically, for example, a two-dimensional code, image information, etc. The scanning device of the detection instrument can obtain the identification information through the second opening 23, and can determine the relevant information of the liquid installed in the reagent cartridge 50 according to the identification information.

[0050] See also Figures 1 to 3 Further, the support structure 11 includes a first support 111 and a second support 112 which are spaced apart and arranged on the bottom surface of the mounting plate 10. A first guide rod 24 is arranged on one side of the cartridge tray 20, and a second guide rod 25 is arranged on the other side of the cartridge tray 20. The first guide rod 24 is movably arranged on the first support 111, and the second guide rod 25 is movably arranged on the second support 112.

[0051] See also Figures 1 to 3 Further, a first linear bearing 113 is provided on the first support 111, and the first guide rod 24 is disposed in the first linear bearing 113. A second linear bearing (not shown) is provided on the second support 112, and the second guide rod 25 is disposed in the second linear bearing.

[0052] See also Figures 1 to 3 In one embodiment, there are at least two first supports 111 , and at least two first supports 111 are arranged along the direction of the first guide rod 24 . There are at least two second supports 112 , and at least two second supports 112 are arranged along the direction of the second guide rod 25 .

[0053] See also Figures 1 to 3In one embodiment, a first boss 114 is provided on one side of the first support 111, and a first guide rod 24 is movably disposed in the first boss 114, and the first guide rod 24 is located below the cartridge tray 20. A second boss (not shown in the figure) is provided on one side of the second support 112, and a second guide rod 25 is movably disposed in the second boss, and the second guide rod 25 is located below the cartridge tray 20. The cartridge tray 20 is located above the first boss 114 and the second boss. In this way, the cartridge tray 20 shields the first guide rod 24 and the second guide rod 25. When the cartridge tray 20 is moved out of the detection chamber, the first guide rod 24 and the second guide rod 25 will not be exposed, and the product appearance can be guaranteed.

[0054] See also Figure 2 and Figure 6 , Figure 6 Shows Figure 2 , in one embodiment, the cartridge in-and-out mechanism further includes a through-beam sensor. The through-beam sensor is used to sense whether the reagent cartridge 50 on the cartridge tray 20 is in place. The through-beam sensor includes a transmitting end 61 disposed at intervals on the mounting plate 10 and a receiving end 62 for receiving the transmission signal of the transmitting end 61. In this way, the cartridge in-and-out mechanism has a detection function for detecting whether the reagent cartridge 50 is in place, which can prevent the operator from making an erroneous operation when the reagent cartridge 50 is not in place.

[0055] See also Figure 2 and Figure 6 Specifically, when the reagent cartridge 50 is placed in place on the cartridge tray 20, the light path emitted by the transmitting end 61 is slightly higher than the upper surface of the reagent cartridge 50, and the height of the higher light path is, for example, 1 mm to 2 mm, that is, the light path emitted by the transmitting end 61 can be received by the receiving end 62, and the receiving end 62 determines that the reagent cartridge 50 is placed in place when receiving the signal emitted by the transmitting end 61; when the reagent cartridge 50 is not placed in place on the cartridge tray 20, for example, two positioning members 291 are provided on the cartridge tray 20, and the positioning members 291 are, for example, pins, and the reagent cartridge The bottom surface of 50 is provided with a socket that cooperates with the positioning piece 291. When the reagent cartridge 50 is not properly placed, the positioning piece 291 is not inserted into the socket but interferes with the bottom surface of the reagent cartridge 50, resulting in the bottom surface of the reagent cartridge 50 not being able to completely adhere to the surface of the cartridge tray 20. At this time, the upper part of the reagent cartridge 50 will block the optical path signal of the transmitting end 61, thereby causing the receiving end 62 to be unable to receive the optical path signal emitted by the transmitting end 61. The corresponding beam sensor determines that the cartridge tray 20 is not in place, and issues an alarm to the staff through the alarm.

[0056] See also Figure 2 and Figure 6In one embodiment, a groove 26 for adapting to the reagent cartridge 50 is provided on the cartridge tray 20. The groove 26 is used to place the reagent cartridge 50. Specifically, two spaced convex portions 261 are provided on the cartridge tray 20, and the two convex portions 261 and the surface of the cartridge tray 20 are enclosed to form the groove 26. In this way, the groove 26 plays a positioning role for the cartridge tray 20, and the reagent cartridge 50 can be stably installed in the groove 26 on the cartridge tray 20, and it is ensured that the reagent cartridge 50 can be quickly placed in place.

[0057] See also Figures 2 to 5 , Figure 4 Shows Figure 3 A schematic diagram of the enlarged structure at A. Figure 5 Shows Figure 3 The enlarged structural diagram at B. In one embodiment, the first push-pull mechanism 30 includes a first fixed plate 31 and a second fixed plate 32 which are fixedly arranged on the mounting plate 10, a first motor 33 mounted on the first fixed plate 31, a first screw rod 34, a screw sleeve 35 matched with the first screw rod 34, and a connecting plate 36 connected to the screw sleeve 35. One end of the first screw rod 34 is connected to the rotating shaft of the first motor 33, and the other end of the first screw rod 34 is rotatably arranged on the second fixed plate 32. The screw sleeve 35 is sleeved on the first screw rod 34, and the connecting plate 36 is connected to the cartridge tray 20. In this way, when the first motor 33 is working, the first motor 33 drives the first screw rod 34 to rotate, the first screw rod 34 correspondingly drives the screw sleeve 35 to move on the first screw rod 34, the screw sleeve 35 drives the connecting plate 36 to move, and the connecting plate 36 drives the cartridge tray 20 to move to achieve entering and exiting the warehouse. It is understandable that the first push-pull mechanism 30 is not limited to the motor screw drive mode in the present embodiment, and can also be, for example, a motor pulley drive mechanism, a motor gear drive mechanism, a cylinder drive mechanism, an electric cylinder drive mechanism or a hydraulic cylinder drive mechanism, etc., as long as it can achieve the movement of the cartridge tray 20. In addition, the end of the first screw 34 is rotatably disposed on the second fixed plate 32, for example, through a rolling bearing.

[0058] See also Figures 1 to 4In one embodiment, the card box in and out of the warehouse mechanism also includes a first photoelectric switch 71 and a second photoelectric switch 72. The first photoelectric switch 71 is arranged on the first fixed plate 31, and the second photoelectric switch 72 is arranged on the second fixed plate 32. A baffle 37 is arranged on the connecting plate 36. When the screw sleeve 35 moves to one end of the first screw rod 34 close to the first fixed plate 31, the baffle 37 moves to the signal transmission port 711 of the first photoelectric switch 71 to cut off the transmission signal of the first photoelectric switch 71; when the screw sleeve 35 moves to one end of the first screw rod 34 close to the second fixed plate 32, the baffle 37 moves to the signal transmission port 711 of the second photoelectric switch 72 to cut off the transmission signal of the second photoelectric switch 72. In this way, when the screw sleeve 35 moves to one end of the first screw rod 34 close to the first fixed plate 31, the baffle 37 moves to the signal transmission port 711 of the first photoelectric switch 71 to cut off the transmission signal of the first photoelectric switch 71. At this time, it indicates that the cartridge tray 20 is driven by the push-pull action of the push-pull mechanism to drive the reagent cartridge 50 thereon to completely enter the detection chamber; when the screw sleeve 35 moves to one end of the first screw rod 34 close to the second fixed plate 32, the baffle 37 moves to the signal transmission port 711 of the second photoelectric switch 72 to cut off the transmission signal of the second photoelectric switch 72. At this time, it indicates that the cartridge tray 20 is driven by the push-pull action of the push-pull mechanism to drive the reagent cartridge 50 thereon to completely move out of the detection chamber.

[0059] Please refer to Figure 7 , Figure 7 The maximum in-and-out stroke of the cartridge tray 20 is as follows: the length of the first guide rod 24 of the cartridge tray 20 is X1, and the distance between at least two first supports 111 arranged on the mounting plate 10 is X2, that is, Figure 6 When the out-of-bin stroke needs to be increased, the length of the cartridge tray 20 and the lengths of the first guide rod 24 and the second guide rod 25 can be adjusted while ensuring that the force point of the reagent cartridge 50 is between the two first supports 111. The structure is simple and compact.

[0060] It should be noted that the "protrusion 261" can be "a part of the card cartridge tray 20", that is, the "protrusion 261" is manufactured integrally with the "other parts of the card cartridge tray 20"; it can also be an independent component separable from the "other parts of the card cartridge tray 20", that is, the "protrusion 261" can be manufactured independently and then combined with the "other parts of the card cartridge tray 20" into a whole.

[0061] It should be noted that the "second fixing plate 32" can be "a part of the first support 111", that is, the "second fixing plate 32" and the "other parts of the first support 111" are manufactured as one piece; it can also be an independent component separable from the "other parts of the first support 111", that is, the "second fixing plate 32" can be manufactured independently and then combined with the "other parts of the first support 111" into a whole.

[0062] It should be noted that the "screw sleeve 35" can be "a part of the connecting plate 36", that is, the "screw sleeve 35" and the "other parts of the connecting plate 36" are manufactured as one piece; it can also be an independent component separable from the "other parts of the connecting plate 36", that is, the "screw sleeve 35" can be manufactured independently and then combined with the "other parts of the connecting plate 36" into a whole.

[0063] See also Figure 1 and Figure 8 , Figure 8 The structure diagram of the cartridge tray 20 and the second push-pull mechanism 40 from one perspective is shown in one embodiment of the present invention. Further, the cartridge in-and-out bin mechanism further includes a guide shaft 81 and a push-pull plate 82. The guide shaft 81 is disposed on the cartridge tray 20. The push-pull plate 82 is movably disposed on the guide shaft 81, and a mating portion 821 for mating with the chip 51 is provided on the push-pull plate 82. The second push-pull mechanism 40 is connected to the push-pull plate 82, and is used to drive the push-pull plate 82 to move along the guide shaft 81. Thus, when it is necessary to draw out the chip 51 of the reagent cartridge 50 mounted on the cartridge tray 20, the mating portion 821 on the push-pull plate 82 is connected to the chip 51, and the push-pull mechanism moves the push-pull plate 82 along the guide shaft 81, and the chip 51 can be drawn out from the reagent cartridge 50 during the movement of the push-pull plate 82 along the guide shaft 81; after the chip 51 is drawn out from the reagent cartridge 50, a series of treatments can be performed on the chip 51, and after the treatments are completed, the second push-pull mechanism 40 moves the push-pull plate 82 in the opposite direction along the guide shaft 81, and the push-pull plate 82 drives the chip 51 into the reagent cartridge 50. Thus, since the second push-pull mechanism 40 is mounted on the cartridge tray 20, the second push-pull mechanism 40 realizes the opening and closing of the chip 51 by driving the push-pull plate 82 to move back and forth along the guide shaft 81, and the overall structure is simple and reliable, and there is no need to add an additional power mechanism inside the detection instrument, so that the structure of the detection instrument is simplified and the cost is reduced.

[0064] See also Figures 8 to 10 , Fig. 9 Shows Figure 8 Schematic diagram of the enlarged structure at C, Fig.10 Shows Fig. 9Schematic diagram of the structure in which the reagent cartridge 50 is separated from the push-pull plate 82. Furthermore, the matching portion 821 is a positioning pin detachably mounted on the push-pull plate 82, and the positioning pin is used to be inserted into the positioning hole 511 of the chip 51. In this way, after the positioning pin is inserted into the positioning hole 511 of the chip 51, it is connected and matched with the chip 51. When the push-pull plate 82 moves along the guide shaft 81, it can drive the chip 51 to move, thereby realizing the opening and closing of the chip 51. In addition, when the reagent cartridge 50 needs to be taken out after the detection process is completed, it can be directly taken from the cartridge tray 20. During the process of taking the reagent cartridge 50, it is separated from the positioning pin on the push-pull plate 82.

[0065] As an optional solution, the matching portion 821 is an alignment hole provided on the push-pull plate 82, and the alignment hole is used to insert the protrusion of the chip 51. Similarly, when the matching portion 821 is an alignment hole, when the protrusion of the chip 51 is inserted into the alignment hole, it is connected and matched with the push-pull plate 82, and when the push-pull plate 82 moves along the guide shaft 81, it can drive the chip 51 to move, so as to realize the opening and closing of the chip 51. In addition, when the reagent cartridge 50 needs to be taken out after the detection process is completed, it can be directly taken out from the cartridge tray 20, and the reagent cartridge 50 is separated from the alignment hole on the push-pull plate 82 during the taking process.

[0066] See also Figures 9 to 12 , Fig.11 Shows Fig. 9 A schematic diagram of a top view of the structure when the chip 51 of the reagent cartridge 50 is fully pulled out, Fig.12 Shows Fig. 9 The schematic diagram of the top view of the structure when the chip 51 is completely located in the reagent cartridge 50, in one embodiment, an anti-slip flange 8211 is arranged around the outer wall of the end of the positioning pin away from the push-pull plate 82. The anti-slip flange 8211 can pass through the positioning hole 511, and the gap formed between the anti-slip flange 8211 and the surface of the push-pull plate 82 can insert the chip 51. In this way, when the push-pull plate 82 pushes and pulls the chip 51, the positioning pin can not only drive the chip 51 to open and close, but also because the edge of the positioning hole 511 of the chip 51 will be inserted into the gap formed between the anti-slip flange 8211 and the surface of the push-pull plate 82, the anti-slip flange 8211 will contact the chip 51 to prevent the chip 51 from escaping from the positioning pin upward during the movement, that is, the stable opening and closing action of the chip 51 can be achieved, and the operation stability is good. In addition, when the reagent cartridge 50 needs to be removed from the cartridge tray 20, in order to prevent the anti-slip flange 8211 from restricting the chip 51, the position of the push-pull plate 82 is adjusted so that the anti-slip flange 8211 moves to a position corresponding to the positioning hole 511. In this way, when the reagent cartridge 50 is taken out upward, the anti-slip flange 8211 passes through the positioning hole 511 and does not interfere with the removal of the reagent cartridge 50.

[0067] See also Figures 8 to 10 In one embodiment, there are two guide shafts 81, and the two guide shafts 81 are respectively arranged on both sides of the cartridge tray 20. In this way, the push-pull plate 82 moves along the two guide shafts 81, and the operation stability of the push-pull plate 82 is good. Optionally, the guide shaft 81 can also be one, three or other numbers, which are not limited here.

[0068] See also Figures 8 to 10 Furthermore, the push-pull plate 82 is provided with a guide hole, a linear bearing or a sliding sleeve 83 corresponding to the guide shaft 81. In this way, the push-pull plate 82 can be directly sleeved on the guide shaft 81 through the provided guide hole and move along the guide shaft 81. In this case, the push-pull plate 82 is specifically made of a wear-resistant plate. The push-pull plate 82 can also be sleeved on the guide shaft 81 through the linear bearing and move along the guide shaft 81. The push-pull plate 82 can also be sleeved on the guide shaft 81 through the sliding sleeve 83 and move along the guide shaft 81 by installing a sliding sleeve 83. The sliding sleeve 83 is specifically made of a wear-resistant sleeve. The volume size of the sliding sleeve 83 is small, so the overall volume size of the push-pull plate 82 is small.

[0069] See also Figures 8 to 10 Furthermore, the guide shaft 81 and the push-pull plate 82 are both located at the second window 21 .

[0070] Generally, when the diameter of the guide shaft 81 is small, it is difficult to machine a blind hole on the cartridge tray 20 that is adapted to the end of the guide shaft 81 and is used to install the end of the guide shaft 81. Fig.13 and Fig.14 , Fig.13 Shows Fig. 9 A schematic diagram of a structure in which one of the pressing pieces 28 and the mounting piece 29 is separated, Fig.14 Shows Fig.13 The enlarged structural diagram at D. Further, the cartridge tray 20 is provided with a mounting groove 27 and a pressing piece 28 detachably mounted at the notch of the mounting groove 27. The number of the mounting grooves 27 corresponds to the number of the ends of the guide shaft 81, the ends of the guide shaft 81 are arranged in the mounting grooves 27, and the pressing piece 28 is pressed and fitted with the side wall of the guide shaft 81. In this way, the width of the mounting groove 27 and the diameter of the guide shaft 81 are clearance-fitted, so that the end of the guide shaft 81 can be mounted in the mounting groove 27. The depth dimension of the mounting groove 27 is slightly smaller than the diameter of the guide shaft 81, so that when the pressing piece 28 is mounted at the notch of the mounting groove 27, it is pressed and fitted with the side wall of the guide shaft 81 to prevent the guide shaft 81 from moving in the mounting groove 27. The cooperation between the end of the guide shaft 81 and the mounting groove 27 plays the role of the cooperation between the guide shaft 81 and the blind hole, but the difficulty of processing the mounting groove 27 is much lower than the difficulty of processing the blind hole here.

[0071] Specifically, the pressing member 28 is fixedly mounted on the cartridge tray 20 via a mounting member 29. The mounting member 29 is, for example, a screw, a bolt, a rivet, etc., which is not limited here.

[0072] See also Figures 8 to 10 In one embodiment, the second push-pull mechanism 40 is a through-shaft motor, which is mounted on the cartridge tray 20 via a third fixing plate 93. The through-shaft motor includes a motor body, a rotating nut (not shown) disposed in the motor body, and a second screw rod 41 that passes through the motor body. The second screw rod 41 is disposed in the rotating nut, and one end of the second screw rod 41 is connected to the push-pull plate 82.

[0073] It can be understood that the second push-pull mechanism 40 is not limited to the through-axis motor in this embodiment, but can also be, for example, a motor pulley drive mechanism, a motor gear drive mechanism, a cylinder drive mechanism, an electric cylinder drive mechanism or a hydraulic cylinder drive mechanism, etc., as long as it can drive the push-pull plate 82 to move.

[0074] See also Figures 8 to 10 In one embodiment, the cartridge tray 20 further includes a first sensor 91 and a second sensor 92. The first sensor 91 is disposed on the third fixing plate 93, and the second sensor 92 is used to be disposed in the detection chamber of the detection instrument. When the end of the second screw rod 41 moves to the first working position, the chip 51 is pulled out of the reagent cartridge 50 by a first preset distance, and the second screw rod 41 can trigger the first sensor 91 accordingly. When the end of the second screw rod 41 moves to the second working position, the chip 51 is completely pulled out of the reagent cartridge 50, and the second screw rod 41 can trigger the second sensor 92 accordingly. In this way, when the second screw rod 41 does not trigger the first sensor 91 and the second sensor 92, it can be indicated that the chip 51 is completely in the reagent cartridge 50; when the second screw rod 41 triggers the first sensor 91, it can be indicated that the chip 51 is pulled out of the reagent cartridge 50 by a first preset distance, and the first preset distance is generally set to be within 1 cm, for example; when the second screw rod 41 triggers the second sensor 92, it can be indicated that the chip 51 is completely pulled out of the reagent cartridge 50. In addition, since the second sensor 92 is not disposed on the cartridge tray 20 but is disposed in the detection chamber of the detection instrument, there is no need to set a connecting plate 36 on the cartridge tray 20 to install the second sensor 92, which can reduce the overall size of the cartridge tray 20.

[0075] It should be noted that the "third fixing plate 93" can be "a part of the card cartridge tray 20", that is, the "third fixing plate 93" and the "other parts of the card cartridge tray 20" are manufactured as one piece; it can also be an independent component separable from the "other parts of the card cartridge tray 20", that is, the "third fixing plate 93" can be manufactured independently and then combined with the "other parts of the card cartridge tray 20" into a whole.

[0076] It should be noted that the "anti-slip flange 8211" can be "a part of the mating part 821", that is, the "anti-slip flange 8211" and the "other parts of the mating part 821" are manufactured as one piece; it can also be an independent component separable from the "other parts of the mating part 821", that is, the "anti-slip flange 8211" can be manufactured independently and then combined with the "other parts of the mating part 821" into a whole.

[0077] Specifically, the first sensor 91 and the second sensor 92 are both photoelectric switches, proximity switches, beam sensors or other types of sensors, as long as they can sense the moving position of the end of the second screw rod 41 and provide timely feedback of the moving position signal of the end of the second screw rod 41.

[0078] Please refer to Figure 1 In one embodiment, a detection instrument includes the card box in-and-out mechanism of any of the above embodiments.

[0079] In the above-mentioned detection instrument, the cartridge tray 20 is movably arranged below the mounting plate 10, so that the bottom of the cartridge tray 20 is suspended, and is not movably arranged above the mounting base plate as in the conventional technology. When the first push-pull mechanism 30 drives the cartridge tray 20 to move to the entry position, and the second push-pull mechanism 40 drives the chip 51 to move outward, the reagent cartridge 50 and the chip 51 are exposed in the first window 12, and the fluorescence intensity detection operation is performed on the liquid in the cartridge tray 20, and the cartridge tray 20 is subjected to the liquid aspiration or liquid replenishment operation, and the detection device above the cartridge tray 20 can perform the detection operation on the chip 51 through the first window 12. After the relevant detection operation is completed, the chip 51 is driven to move inward into the reagent cartridge 50 by the second push-pull mechanism 40, and the cartridge tray 20 is moved to the exit position by the first push-pull mechanism 30. In this way, during the detection operation, the detection device above the card box tray 20 can avoid interference with the installation base plate, thereby ensuring that the relevant detection operations are carried out smoothly, the work efficiency is high, and the overall structure is relatively simple.
