Most of them are compounds containing benzene rings or heterocycles and conjugated double bonds. Fluorescent dyes can be used alone or in combination into composite fluorescent dyes. Fluorescent dye molecules need to be detected by detection equipment before use.

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1-5 As shown, a fluorescent dye molecule detection device of this utility model includes a workbench 1, a detection box 2 fixedly connected to the top of the workbench 1, a light source 21 and a detection probe 18 disposed inside the top of the detection box 2, and a receiving plate 6 disposed inside the bottom of the detection box 2; a placement groove 7 is embedded in the top of the receiving plate 6; a mounting frame 9 is fixedly connected to the bottom of the receiving plate 6, a first motor 8 is fixedly connected to the top of the mounting frame 9, the output shaft of the first motor 8 is fixedly connected to the bottom of the placement groove 7, and the output shaft of the first motor 8 is rotatably connected to the receiving plate 6 through a bearing; sliding rods 5 are fixedly connected to both ends of the receiving plate 6, and slide rails 4 are symmetrically fixed to the inner walls on both sides of the detection box 2, and the sliding rods 5 are slidably connected within the slide rails 4; a plurality of anti-slip grooves 22 are opened at one end of the receiving plate 6.

[0028] During operation, fluorescent dyes include both liquid and solid forms. If the dye is liquid, it can flow freely to ensure even distribution. If the dye is solid, uneven stacking may prevent some fluorescent dye molecules from being effectively excited, leading to deviations in fluorescence detection. The fluorescent dye is poured into the placement tank 7, and the receiving plate 6 is mounted on the slide rail 4 using the cooperation of the slide rod 5 and the slide rail 4. During detection, the first motor 8 needs to be turned on, which drives the placement tank 7 to rotate. The placement tank 7 then drives the fluorescent dye to rotate. Rotation can redistribute the sample particles, more accurately reflecting the overall fluorescence of the sample. Rotation ensures that fluorescent dye molecules at all levels, from the surface to the interior, can be effectively excited.

[0029] Furthermore, such as Figure 5As shown, a second motor 10 is fixedly connected to the top of the detection box 2. The output shaft of the second motor 10 is rotatably connected to the detection box 2 and is fixedly connected to a rotating frame 11. The second motor 10 is located at one end of the rotating frame 11. A reciprocating lead screw 12 is rotatably connected to the rotating frame 11 via a bearing. A moving block 15 is threaded onto the reciprocating lead screw 12. A second side plate 19 is fixedly connected to one side wall of the moving block 15. A second electric push rod 20 is fixedly connected to the bottom of the second side plate 19. A light source 21 is installed on the output end of the second electric push rod 20. A third motor 14 is provided at one end of the reciprocating lead screw 12. The rotating frame 11 is longer than the radius of the placement slot 7.

[0030] During operation, when testing, the fluorescence needs to be excited by the light source 21. By turning on the third motor 14, the output shaft of the third motor 14 drives the reciprocating screw 12 to rotate. The reciprocating screw 12 drives the moving block 15 to reciprocate. The moving block 15 drives the second side plate 19 to reciprocate. The second side plate 19 drives the second electric push rod 20 and the light source 21 to move. At the same time, the second motor 10 is turned on. Through the cooperation of the second motor 10 and the third motor 14, the light source 21 can rotate above the entire placement tank 7, so that there are no dead corners in the fluorescent dye in the placement tank 7 illuminated by the light source 21. By setting the second electric push rod 20, the height of the light source 21 can be easily adjusted, so that the light source 21 can be used to irradiate fluorescent dyes of different thicknesses. The rotating frame 11 rotates in the opposite direction to the placement tank 7.

[0031] Furthermore, such as Figure 5 As shown, a first side plate 16 is fixedly connected to the other side wall of the movable block 15, a first electric actuator 17 is fixedly connected to the bottom of the first side plate 16, and a detection probe 18 is installed on the output end of the first electric actuator 17.

[0032] During operation, by setting the detection probe 18, the fluorescent dye after being irradiated by the light source 21 is activated to start detection. The excitation light source 21 emits excitation light according to the set parameters, which is transmitted through the optical path to irradiate the fluorescent dye. The fluorescence signal generated by the fluorescent dye is received by the detection probe 18 and converted into an electrical signal. The data is transmitted to the data processing system for data analysis.

[0033] Furthermore, such as Figure 3 As shown, a temperature sensor 23 is installed on the top inner wall of the detection box 2, and a dustproof plate 26 is installed on the detection box 2 through a hole; a first fan 25 is installed on the inner wall of the dustproof plate 26; an electric heating wire 24 is provided on the inner side of the first fan 25, and the electric heating wire 24 is electrically connected to the temperature sensor 23.

[0034] During operation, different fluorescent dyes are suitable for different ambient temperatures. The temperature inside the detection chamber 2 is monitored by the temperature sensor 23. Then, the first fan 25 and the heating wire 24 are powered on. The heating wire 24 generates heat, which is blown into the detection chamber 2 by the first fan 25 to keep the fluorescent dye at a suitable temperature for excitation.

[0035] Furthermore, such as Figure 1 As shown, a mounting frame 27 is fixed to the top of the detection box 2, and a second fan 28 is installed inside the mounting frame 27. The second fan 28 is electrically connected to the temperature sensor 23.

[0036] During operation, after the test is completed, the receiving plate 6 needs to be removed, the temperature inside the test chamber 2 is monitored by the temperature sensor 23, and then the second fan 28 is controlled to exhaust the heat to prevent high temperature injury to the operator.

[0037] Furthermore, such as Figure 1 As shown, a sealing plate 3 is slidably connected to the side wall of the detection box 2 away from the first fan 25, and a handle 32 is fixedly connected to the outer wall of the sealing plate 3; a first magnetic block 31 is fixedly connected to the side wall of the detection box 2, and the first magnetic block 31 is in contact with the top of the handle 32; a second magnetic block 33 is embedded and fixedly connected to the top of the workbench 1, and the second magnetic block 33 is in contact with the bottom of the handle 32.

[0038] During operation, the sealing plate 3 is used to seal the detection box 2. During the placement of the receiving plate 6, the handle 32 needs to be lifted upwards to engage with the first magnetic block 31. After the receiving plate 6 is placed, the handle 32 needs to be pulled downwards to engage with the second magnetic block 33 to maintain the sealing of the detection box 2.

[0039] Furthermore, such as Figure 1 As shown, a controller 30 and a transparent window 29 are installed on the side wall of the detection box 2, and the controller 30 is electrically connected to the detection probe 18.

[0040] During operation, the transparent window 29 facilitates observation of the state inside the detection box 2; the controller 30, which is electrically connected to the detection probe 18, facilitates receiving the detection data from the detection probe 18 and performing data processing.

[0041] Furthermore, such as Figure 5 As shown, two guide rods 13 are fixedly connected to the rotating frame 11, and the moving block 15 is slidably connected to the two guide rods 13.

[0042] During operation, the movable block 15 slides on the guide rod 13, which limits the movement of the movable block 15 in the horizontal direction.

[0043] Working principle: Fluorescent dye is poured into the placement tank 7. The receiving plate 6 is installed on the slide rail 4 through the cooperation of the slide rod 5 and the slide rail 4. During detection, the first motor 8 is turned on, which drives the placement tank 7 to rotate. The placement tank 7 drives the fluorescent dye to rotate. The rotation can redistribute the sample particles, more accurately reflecting the overall fluorescence of the sample. The rotation ensures that fluorescent pigment molecules at all levels from the surface to the interior can be effectively excited. During detection, the fluorescence is excited by the light source 21. The third motor 14 is turned on, and the output shaft of the third motor 14 drives the reciprocating screw 12 to rotate. The reciprocating screw 12 drives the moving block 15 to reciprocate. The moving block 15 drives the second side plate 19 to reciprocate. The second side plate 19 drives the second electric push rod 20 and the light source 21 to reciprocate. The light source 21 moves, and simultaneously the second motor 10 is activated. Through the cooperation of the second motor 10 and the third motor 14, the light source 21 can rotate above the entire placement tank 7, ensuring that there are no blind spots in the fluorescent dye within the placement tank 7 where the light source 21 will irradiate. By setting a second electric push rod 20, the height of the light source 21 can be easily adjusted, making the light source 21 suitable for irradiating fluorescent dyes of different thicknesses. The rotating frame 11 rotates in the opposite direction to the placement tank 7. By setting a detection probe 18, after the fluorescent dye is irradiated by the light source 21, the detection probe 18 is activated to start detection. The excitation light source 21 emits excitation light according to the set parameters, which is transmitted through the optical path and irradiates the fluorescent dye. The fluorescence signal generated by the fluorescent dye is received by the detection probe 18 and converted into an electrical signal. The data is transmitted to the data processing system for data analysis.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
