[0029] When the first plug rod 27 and the second plug rod 28 on the left side of the first connecting block 23 and the second connecting block 24 move away from the slot, the first plug rod 27 and the second plug rod 28 on the left side of the first connecting block 23 and the second connecting block 24 drive the movable plate 30 to move inside the movable opening, and the first magnetic block 22 and the second magnetic block 36 at the bottom of the movable plate 30 drive the limiting plate 21 to move inside the movable groove, so that the limiting plate 21 moves away from the end of the first magnetic block 22 to the side away from the slider 20, so that the first connecting block 23 and the second connecting block 24 are no longer connected, and the slider 20 is no longer limited, so that it is convenient to remove the fixed plate 17 and multiple spotting needles 19 from the mounting plate 14 at the same time, reducing the steps of installation and replacement and improving usage efficiency.

[0030] The detection device box 2 controls the first moving mechanism 7 to drive the second moving mechanism 8 to move to the top of the detection solution drawing plate 4, so that the second moving mechanism 8 drives the connecting plate 9, the mounting block 10 and the rotating block 11 to move, so that the injection pump 18 and the sample spotting needle 19 move to the top of the detection solution drawing plate 4, and the first electric push rod 12 is started to drive the fixed block 13 to move downward, and the rotating structure is extended to make the rotating block 11 and the mounting plate 14 drive the injection pump 18 and the sample spotting needle 19 to move downward, and the injection pump 18 is started to absorb the solution inside the detection solution drawing plate 4 into the inside of the sample spotting needle 19, and then the first moving mechanism 7 and the second moving mechanism 8 are used to move the sample spotting needle 19 to the detection sample spotting area 5, and then the sample spotting needle 19 is moved to the detection sample spotting area 5. The first electric push rod 12 moves downward to move the sample spotting needle 19 to a suitable distance from the detection sample spotting area 5, and the movement of the first electric push rod 12 is stopped to fix the position of the sample spotting needle 19. Then, the first moving mechanism 7 and the second moving mechanism 8 are moved to spot the solution absorbed by the sample spotting needle 19. After the spotting is completed, the sample spotting needle 19 is moved to the cleaning and air-drying structure 6 by the first moving mechanism 7 and the second moving mechanism 8. The first electric push rod 12 is used to move the sample spotting needle 19 to the inside of the cleaning and air-drying structure 6 to clean the sample spotting needle 19, so as to continue to absorb different solutions for spotting. When the sample spotting needle 19 needs to be replaced, the sample spotting needle 19 is moved by the first moving mechanism 7. 9 is moved to the opening of the detection operation box 1, and the first connecting block 23 and the second connecting block 24 are no longer connected by moving the fixing structure, and the limiting plate 21 is no longer plugged into the limiting groove on one side of the slider 20, and the fixing plate 17 is moved to make the slider 20 move inside the slide groove, and the fixing plate 17 drives multiple sample needles 19 to move. When the slider 20 moves out of the slide groove, the fixing plate 17 drives the sample needles 19 to be removed from the mounting plate 14 and the support plate 15, and then the fixing plate 17 with new sample needles 19 is installed on the mounting plate 14, and the slider 20 on one side of the new fixing plate 17 is placed in the slide groove, and the fixing plate 17 drives the new sample needle 19 to move along the slide groove by moving the slider 20. When the slider 20 moves When it fits with the inner wall of one end of the slide groove, the fixed plate 17 drives the sample spotting needle 19 and the second connecting block 24 to move to the bottom of the second connecting block 24, and supports the fixed plate 17 through the support plate 15, and then moves the fixed structure to connect the first connecting block 23 with the second connecting block 24, so that the injection pump 18 is connected to the sample spotting needle 19. At the same time, the movement of the fixed structure, through the action of the first magnetic block 22, makes the limiting plate 21 inserted into the limiting groove, so that the slider 20 and the fixed plate 17 are fixed on one side of the mounting plate 14, so that the new sample spotting needle 19 is installed at the bottom of the injection pump 18, so that multiple sample spotting needles 19 can be replaced at one time, which is convenient for improving the replacement efficiency and facilitating rapid sample spotting.

[0031] like Figures 3 to 7As shown, one end of the fixing plate 17 is located at the top of the supporting plate 15, a mounting hole is provided on the fixing plate 17, the first connecting block 23 is located at the top of the mounting hole, the top of the spotting needle 19 and the second connecting block 24 are located inside the mounting hole, the bottom of the first connecting block 23 is in contact with the top of the second connecting block 24, slots are provided on both sides of the first connecting block 23 and the second connecting block 24, the number of the fixing structure is the same as that of the injection pump 18 and the spotting needle 19, the fixing structure is located on one side of the first connecting block 23 and the second connecting block 24 and is distributed in a linear array, the mounting plate 14, the supporting plate 15, the fixing plate 17, the mounting frame 16, the first connecting block 23, the second connecting block 24, the injection pump 18 and the spotting needle 19 are symmetrically arranged with the center of the fixing block 13.

[0032] The support plate 15 is used to support the fixing plate 17, so as to improve the stability of the fixing plate 17 and the sample spotting needle 19 when they are installed. The mounting hole is used to install the sample spotting needle 19 on the fixing plate 17. The slot is used to connect the first connecting block 23 and the second connecting block 24 with the fixing structure, so as to connect the first connecting block 23 and the second connecting block 24, so that the sample spotting needle 19 is connected to the injection pump 18. The mounting plate 14, the support plate 15, the fixing plate 17, the mounting frame 16, the first connecting block 23, the second connecting block 24, the injection pump 18 and the sample spotting needle 19 are symmetrically arranged around the center of the fixing block 13, so as to facilitate the rotation of the rotating structure, so that the sample spotting needle 19 on the front side and the sample spotting needle 19 on the rear side can be switched, so that the sample spotting needle 19 on one side can be used continuously after the sample spotting needle 19 on the other side is used, so as to reduce the number of replacements and improve the sample spotting effect.

[0033] like Figures 4 to 6 As shown, the mounting plate 14 is located at the bottom of one end of the mounting block 10, and is fixedly installed with the rotating block 11 away from the side of the fixed block 13. A fixing groove is provided at the bottom of the mounting block 10 and the top of the rotating block 11, and a rotating structure is arranged inside the fixing groove. A mounting groove is provided on the side of the rotating block 11 close to the mounting plate 14, and a limiting hole is provided on one side of the fixed block 13. A second electric push rod 25 is fixedly installed inside the mounting groove, and a limiting rod 26 is fixedly installed at one end of the second electric push rod 25, and one end of the limiting rod 26 passes through the mounting groove and is plugged into the mounting plate 14 and the limiting hole.

[0034] The rotating block 11 and the mounting plate 14 are driven to rotate by the rotating structure, so that the injection pump 18 and the sample spotting needle 19 on one side of the mounting plate 14 are switched positions, which is convenient for the sample spotting needle 19 on the rear side of the rotating block 11 to draw solution for sample spotting, thereby facilitating improving the efficiency of sample spotting. The limiting rod 26 is connected to the fixed block 13, so that when the second electric push rod 25 pushes the fixed block 13 to move downward, the rotating block 11 can be driven to move downward, so that the injection pump 18 and the sample spotting needle 19 on one side of the mounting plate 14 are moved downward, which is convenient for drawing solution and sample spotting. When the rotating block 11 rotates, the second electric push rod 25 drives the insertion rod to move into the mounting groove, so that the limiting rod 26 no longer limits the fixed block 13, preventing the fixed block 13 and the limiting rod 26 from limiting the rotation of the rotating block 11 when the rotating block 11 rotates, which is not convenient for the rotating block 11 to rotate, causing the sample spotting needle 19 to be switched, affecting the efficiency of sample spotting.

[0035] like Figures 7 to 9 As shown, a movable opening is opened at one end of the fixed plate 17 near the mounting plate 14, a slide groove passes through one end of the mounting plate 14, the slide groove is connected with the movable groove, the bottom of the limiting plate 21 is slidably connected with the inner wall of the bottom of the movable groove, the shape of the limiting plate 21 is U-shaped, one end of the limiting plate 21 passes through the movable extension to the inside of the slide groove, the other end of the limiting plate 21 is located at the bottom of the movable opening, and the top of the first magnetic block 22 is flush with the bottom of the fixed plate 17.

[0036] The U-shaped limiting plate 21 is used to facilitate the plugging of one end of the limiting plate 21 with the slider 20. The movable opening facilitates the movement of the fixed structure, and the top of the first magnetic block 22 is flush with the bottom of the fixed plate 17, so that the first magnetic block 22 at the other end of the limiting plate 21 is connected to the fixed structure. When the fixed structure moves, the limiting plate 21 moves along the inner wall of the movable groove, so that the limiting plate 21 can be plugged into and separated from the limiting groove on one side of the slider 20, which is convenient for the installation and replacement of the spotting needle 19 on the fixed plate 17 and is easy to use.

[0037] like Figures 8 to 9As shown, the fixed structure includes a first plug rod 27, a second plug rod 28 is arranged at the bottom of the first plug rod 27, the first plug rod 27 is plugged into the slots on both sides of the first connecting block 23, and the second plug rod 28 is plugged into the slots on both sides of the second connecting block 24. A moving block 29 is fixedly installed at one end of the first plug rod 27 and the second plug rod 28 on the right side of the first connecting block 23 and the second connecting block 24, a moving plate 30 is fixedly installed at one end of the first plug rod 27 and the second plug rod 28 on the left side of the first connecting block 23 and the second connecting block 24, a fixing rod 31 is fixedly connected to the right side of the second plug rod 28 on the right side of the second connecting block 24, and a first rack 32 is fixedly installed at one end of the fixing rod 31 A gear 33 is meshed inside one side of the first rack 32, and a second rack 34 is meshed on one side of the gear 33. A connecting rod 35 is fixedly connected to one end of the second rack 34, and one end of the connecting rod 35 is fixedly connected to the second plug rod 28 on the left side of the second connecting block 24. The moving blocks 29 are connected by a movable rod. The first plug rod 27 is located at the top of the fixed plate 17, the second plug rod 28 is located inside the fixed plate 17, and the moving block 29 is located on the side of the fixed plate 17 away from the mounting frame 16. The first rack 32 and the second rack 34 are both slidably connected to the inner wall of the fixed plate 17, and a rotating rod is fixedly installed in the middle of the gear 33. The upper and lower ends of the rotating rod are rotatably connected to the inner wall of the fixed plate 17.

[0038] By moving the moving block 29, the first plug rod 27 and the second plug rod 28 on the right side of the first connecting block 23 and the second connecting block 24 are driven to move in a direction away from the slot. Since the second plug rod 28 is located inside the fixed plate 17, when the second plug rod 28 moves, it can drive the fixed rod 31 and the first rack 32 to move, and the first rack 32 moves in a direction away from the slot on the right side of the first connecting block 23 and the second connecting block 24, so that the gear 33 drives the rotating rod to rotate, so that the second rack 34 drives the connecting rod 35 to move in the opposite direction of the first rack 32, and the connecting rod 35 is connected. The movement of the rod 35 drives the first plug rod 27 and the second plug rod 28 on the left side of the first connecting block 23 and the second connecting block 24 to move toward the second rack 34, so that the first plug rod 27 and the second plug rod 28 are no longer plugged into the slots on both sides of the first connecting block 23 and the second connecting block 24, so that the first connecting block 23 and the second connecting block 24 are no longer connected. The movable rod is connected to the moving block 29, which is convenient for simultaneously separating multiple first plug rods 27 and the second plug rod 28 from multiple first connecting blocks 23 and second connecting blocks, so that multiple spotting needles 19 can be replaced at the same time.

[0039] like Figures 4 to 6As shown, the rotating structure includes a servo motor 37, and the output end of the servo motor 37 is transmission-connected with a telescopic rod 38. Two fixing holes are provided at the bottom of the fixed block 13, and a limiting block 39 is rotatably connected inside the fixing hole. A limiting opening is provided at the bottom of the limiting block 39, and limiting rods 40 are provided on both sides of the bottom end of the telescopic rod 38. One end of the limiting rod 40 passes through the fixing groove and is plugged into the limiting opening.

[0040] When it is necessary to switch the positions of the spotting needles 19 on the front and rear sides of the rotating block 11, when the limiting rod 26 no longer limits the fixed block 13, the servo motor 37 is started to drive the telescopic rod 38 to rotate, so that the rotating block 11 rotates 180 degrees, and at the same time, the limiting rod 40 rotates inside the limiting opening inside the limiting block 39, so that the spotting needle 19 on the front side of the rotating block 11 and the spotting needle 19 on the rear side switch positions. After the conversion is completed, the second electric push rod 25 and the limiting rod 26 are connected to the fixed block 13, and the fixed block 13 and the rotating block 11 are pushed downward by the first electric push rod 12. When the rotating block 11 moves, the telescopic rod 38 The limiting rod 40 moves downward and separates from the limiting block 39, so that the mounting plate 14 drives the injection pump 18 and the sample spotting needle 19 on one side thereof to move downward to draw the solution or to spot the sample. When the solution is drawn or the sample is spotted, the second electric push rod 25 moves upward, so that the rotating block 11 drives the mounting plate 14, the injection pump 18 and the sample spotting needle 19 back to their original positions. At the same time, the telescopic rod 38 contracts, so that the limiting rod moves upward and is inserted into the limiting opening inside the limiting block 39 again, so that the rotating block 11 is fixed, so that the position of the injection pump 18 and the sample spotting needle 19 on one side of the mounting plate 14 is fixed, so as to improve the stability.

[0041] Working principle: When in use, the detection device box 2 controls the first moving mechanism 7 to drive the second moving mechanism 8 to move to the top of the detection solution drawing plate 4, so that the second moving mechanism 8 drives the connecting plate 9, the mounting block 10 and the rotating block 11 to move, so that the injection pump 18 and the spotting needle 19 move to the top of the detection solution drawing plate 4, and the first electric push rod 12 is started to drive the fixed block 13 to move downward, and the rotating block 11 and the mounting block 10 are connected to the connecting plate 9, the mounting block 10 and the rotating block 11 are connected to the connecting plate 9, the mounting block 10 and the rotating block 11 are connected to the connecting plate 9, the mounting block 10 and the rotating block 11 are connected to the connecting plate 9, the mounting block 10 and the rotating block 11 are connected to the connecting plate 9, the mounting block 10 and the rotating block 11 are connected to the connecting plate 9, the mounting block 10 and the rotating block 11 are connected to the connecting plate 9, the connecting plate 9 and the rotating block 11 are connected to the connecting plate 9, the connecting plate 9 and the rotating block 11 are connected to the connecting plate 1 ... connecting plate 11 The internal telescopic rod 38 is extended, so that the rotating block 11 and the mounting plate 14 drive the injection pump 18 and the sample spotting needle 19 to move downward, and the injection pump 18 is started to absorb the solution inside the detection solution absorption plate 4 into the inside of the sample spotting needle 19, and then the sample spotting needle 19 is moved to the detection sample spotting area 5 by the first moving mechanism 7 and the second moving mechanism 8, and the sample spotting needle 19 is moved to a suitable distance from the detection sample spotting area 5 by the first electric push rod 12. The movement of the first electric push rod 12 is stopped, so that the position of the sample spotting needle 19 is fixed, and then the solution absorbed by the sample spotting needle 19 is used for the detection sample spotting area 5 by the movement of the first moving mechanism 7 and the second moving mechanism 8. After the spotting is completed, the spotting needle 19 is moved to the cleaning and air-drying structure 6 by the first moving mechanism 7 and the second moving mechanism 8, and the spotting needle 19 is moved to the inside of the cleaning and air-drying structure 6 by the first electric push rod 12 to clean the spotting needle 19, so as to continue to draw different solutions for spotting. When the spotting needle 19 needs to be replaced, the first plugging rod 27 and the second plugging rod 28 on the right side of the first connecting block 23 and the second connecting block 24 are driven by the moving block 29 to move away from the slot. Since the second plugging rod 28 is located inside the fixed plate 17, when the second plugging rod 28 moves, it can drive the fixed rod 31 and the first rack 32 moves, the first rack 32 moves in the direction away from the slot on the right side of the first connecting block 23 and the second connecting block 24, so that the gear 33 drives the rotating rod to rotate along the inner wall of the fixing plate 17, so that the second rack 34 drives the connecting rod 35 to move in the opposite direction of the first rack 32, and the connecting rod 35 moves to drive the first plug rod 27 and the second plug rod 28 on the left side of the first connecting block 23 and the second connecting block 24 to move in the direction of the second rack 34, so that the first plug rod 27 and the second plug rod 28 are no longer plugged into the slots on both sides of the first connecting block 23 and the second connecting block 24, so that the first connecting block 23 and the second connecting block 24 are no longer connected. When the first connecting block 23 and the first plug rod 27 and the second plug rod 28 on the left side of the second connecting block 24 move away from the slot, the first connecting block 23 and the first plug rod 27 and the second plug rod 28 on the left side of the second connecting block 24 drive the movable plate 30 to move inside the movable opening, and the first magnetic block 22 and the second magnetic block 36 at the bottom of the movable plate 30 drive the limiting plate 21 to move inside the movable groove, so that the limiting plate 21 moves away from one end of the first magnetic block 22 to the side away from the slider 20, so that the limiting plate 21 is no longer plugged into the limiting groove on one side of the slider 20, and the slider 20 is no longer limited. When the first connecting block 23 and the second connecting block 24 are no longer connected,When the slider 20 is no longer restricted in the chute, the first magnetic block 22 is separated from the second magnetic block 36 by moving the fixed plate 17. When the slider 20 moves out of the chute, the fixed plate 17 drives the multiple sample needles 19 to be removed from the mounting plate 14. Then, a new fixed plate 17 and the sample needles 19 are installed on the mounting plate 14, so that the injection pump 18 is connected to the sample needles 19.

[0042] When the sample spotting needle 19 on the front side needs to be replaced after use, the second electric push rod 25 is started to drive the limit rod 26 to move, so that the limit rod 26 is away from the limit hole and no longer limits the fixed block 13. The fixed block 13 is driven by the first electric telescopic rod 38 to move upward away from the mounting plate 14. The servo motor 37 is started to drive the telescopic rod 38 to rotate, so that the rotating block 11 rotates 180 degrees. At the same time, the limiting rod 40 rotates inside the limiting opening inside the limiting block 39, so that the sample spotting needle 19 on the front side of the rotating block 11 and the sample spotting needle 19 on the rear side switch positions. After the conversion is completed, the fixed block 13 is connected by plugging the second electric push rod 25 and the limit rod 26 with the limit hole. The first electric push rod 12 pushes the fixed block 13 and the rotating block 11 to move downward. When the rotating block 11 moves, the telescopic rod 38 is extended, and the limiting rod 40 moves downward and separates from the limiting block 39, so that the mounting plate 14 drives the injection pump 18 and the sample spotting needle 19 on one side thereof to move downward to draw solution or spot.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them.
