Description

Technical Field

[0001] This application relates to the field of spectral detection technology, and in particular to a rapid cleaning module. Background Technology

[0002] In the field of modern spectroscopic detection technology, whether for scientific research in the laboratory or for the precise measurement of the spectral characteristics of liquid samples in industrial production, reagent injection is required for different samples. Since different samples may require different reagents, and some reagents are highly acidic or alkaline, it is necessary to thoroughly clean the pipette tip after each reagent injection before injecting a new sample.

[0003] To address this need, the industry employs various cleaning methods for nozzles and injection lines. Common methods include manual cleaning, static immersion cleaning, high-pressure water jet rinsing, and ultrasonic cleaning. While manual cleaning is simple and easy to perform, it is time-consuming and prone to human error; static immersion cleaning can thoroughly remove residues, but it also takes a long time; high-pressure water jet rinsing significantly increases cleaning speed, but its effectiveness against some stubborn residues is limited; ultrasonic cleaning combines physical and chemical actions, and can more effectively remove various types of dirt, but the equipment is expensive and the operation is complex.

[0004] Current cleaning methods have several shortcomings. Firstly, the cleaning speed is slow, making it difficult to meet the demands of high-efficiency detection. In some industrial production environments with high detection efficiency requirements, prolonged cleaning processes can severely impact production schedules. Secondly, for reagents with high acidity or alkalinity, large amounts of rinsing solution are needed. Existing cleaning devices often cannot quickly and effectively complete large-volume rinsing, resulting in incomplete cleaning. Residual reagents may interfere with subsequent sample detection results, reducing the accuracy of spectral detection. Utility Model Content

[0005] To improve the accuracy of spectral detection, this application provides a rapid cleaning module.

[0006] The rapid cleaning module provided in this application adopts the following technical solution:

[0007] A rapid cleaning module includes an experimental platform, a rotating test tube tray, a Z-axis module, a liquid injection gun, and an electronic control module. The liquid injection gun includes a nozzle and a liquid injection tube. The Z-axis module is electrically connected to the electronic control module and is vertically arranged. The nozzle is mounted on a moving block of the Z-axis module. The liquid injection tube is connected to an external reagent supply device. The experimental platform is provided with a cleaning pool that slides downward toward the nozzle, and the experimental platform is provided with a driving component to drive the cleaning pool to slide. The side wall of the cleaning pool has a liquid extraction port communicating with the inner cavity. The experimental platform is also provided with a liquid extraction pump, and a liquid extraction tube is connected between the liquid extraction pump and the liquid extraction port to extract waste liquid from the cleaning pool.

[0008] By adopting the above technical solution, the sliding cleaning tank on the experimental platform can not only be quickly moved under the pipette tip when cleaning is needed, but also features a highly efficient liquid extraction system to ensure that waste liquid is discharged in a timely manner, avoiding contamination of subsequent samples. This design not only improves the cleaning speed but also effectively reduces cross-contamination caused by incomplete cleaning, thereby enhancing the accuracy and reliability of spectral detection.

[0009] Optionally, the cleaning tank is provided with a guide channel, the liquid extraction port is located at the end of the guide channel, and the width of the guide channel is set to match the liquid extraction port. The bottom wall of the guide channel is inclined in the direction towards the liquid extraction port. A guide slope is also provided between the side top wall of the guide channel and the inner side wall of the cleaning tank to guide the waste liquid to flow into the guide channel.

[0010] By adopting the above technical solution, the guide channel and guide slope designed inside the cleaning tank can effectively guide the waste liquid to the extraction port, ensuring that the waste liquid is discharged in time, avoiding the accumulation of waste liquid in the cleaning tank, ensuring the thoroughness of cleaning, and reducing the impact of residual reagents on the subsequent sample test results.

[0011] Optionally, the experimental platform is provided with a linear guide rail, and a slider is slidably mounted on the linear guide rail. The cleaning tank is connected to the slider. The driving component includes a lead screw rotatably mounted on the linear guide rail and a stepper motor that drives the lead screw to rotate. The lead screw is parallel to the linear guide rail, and the lead screw passes through the slider via a threaded connection.

[0012] By adopting the above technical solution, the linear guide rail and slider configuration enable the cleaning tank to move smoothly along a predetermined path, ensuring effective coverage of the area below the nozzle, thereby achieving comprehensive and efficient cleaning. Simultaneously, the drive mechanism consisting of a lead screw and a stepper motor precisely controls the movement position and speed of the cleaning tank, improving the automation and accuracy of the cleaning process, and further enhancing the accuracy and efficiency of spectral detection.

[0013] Optionally, the Z-axis module's moving block is provided with a mounting base, the gun head is inserted into the mounting base, and connecting edges extend from both sides of the gun head. Mounting holes are correspondingly opened between the connecting edges and the mounting base, and fixing bolts are inserted into the two mating mounting holes to fix the gun head on the mounting base.

[0014] By adopting the above technical solution, the detachable connection design between the nozzle and the mounting base makes replacing or repairing the nozzle more convenient, reducing the possibility of the entire cleaning module being affected by nozzle damage. At the same time, this structure improves the stability and sealing of the nozzle, ensuring that leakage is less likely to occur during high-pressure rinsing, thereby guaranteeing the consistency and reliability of the cleaning effect.

[0015] Optionally, the bottom of the mounting base is provided with an anti-overflow protrusion. The anti-overflow protrusion includes a coaxially arranged insertion part and a supporting part. The insertion part is located below the supporting part and is inserted into the cleaning tank. The bottom end of the nozzle of the gun head passes through the supporting part and extends into the insertion part. When the insertion part is inserted into the cleaning tank, the supporting part abuts against the side top wall of the cleaning tank.

[0016] By adopting the above technical solution, the anti-overflow protrusion can form a stable support structure when the nozzle is inserted into the cleaning tank, effectively preventing waste liquid from overflowing during the cleaning process due to excessive insertion of the nozzle. At the same time, the design of the insertion part not only ensures that the outer wall of the nozzle nozzle can be effectively cleaned, but also avoids the risk of damage to the bottom of the nozzle nozzle due to impact, further improving the safety and cleanliness of the cleaning process.

[0017] Optionally, a fixed bracket is connected to the side wall of the moving block of the Z-axis module, and a heating module for heating the injection pipe is provided on the fixed bracket, through which the injection pipe passes.

[0018] By adopting the above technical solution, the temperature of the rinsing fluid in the injection tube can be effectively increased, thereby accelerating the chemical reaction rate during the cleaning process and improving cleaning efficiency. Simultaneously, the heated rinsing fluid can better dissolve or decompose sparingly soluble substances adhering to the nozzle surface, ensuring more thorough cleaning, reducing the impact of residues on subsequent sample detection, and further improving the accuracy and reliability of spectral detection.

[0019] Optionally, the heating module includes a heating block and a heat insulation cover that covers the heating block. The outer wall of the heating block is provided with a threaded groove. The liquid injection pipe passes between the heating block and the heat insulation cover and is wound around the threaded groove along the groove shape.

[0020] By adopting the above technical solution, the liquid tube is wound within the threaded groove between the heating block and the insulation cover, which effectively increases the heating area of ​​the injection tube, making the temperature of the rinsing liquid inside the injection tube more uniform, thereby ensuring the cleanliness of the nozzle and the consistency of the cleaning effect during the cleaning process. At the same time, the design of the insulation cover can also reduce heat loss and improve energy utilization efficiency.

[0021] Optionally, the experimental platform is provided with a summarizing board, and the summarizing board has multiple through holes distributed vertically along the edge, with the liquid extraction tube and the liquid injection tube corresponding one-to-one with the through holes.

[0022] By adopting the above technical solutions, the design of the sorting plate allows for the neat arrangement of the suction and injection pipes, avoiding pipe tangling and confusion, and improving the overall cleanliness of the module. Simultaneously, the through-hole design ensures that each pipe has a fixed path, reducing mutual interference between pipes and facilitating maintenance and replacement. This design not only enhances the ease of operation of the equipment but also effectively prevents misoperation or damage caused by disordered pipes.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The sliding cleaning tank on the experimental platform can be quickly moved under the pipette tip when cleaning is needed, and it is equipped with a high-efficiency liquid extraction system to ensure that waste liquid is discharged in a timely manner, avoiding contamination of subsequent samples. This design not only improves the cleaning speed, but also effectively reduces cross-contamination caused by incomplete cleaning, thereby improving the accuracy and reliability of spectral detection;

[0025] 2. The guide channel and guide slope designed inside the cleaning tank can effectively guide the waste liquid to the extraction port, ensuring that the waste liquid is discharged in time, avoiding the accumulation of waste liquid in the cleaning tank, ensuring the thoroughness of cleaning, and reducing the impact of residual reagents on the subsequent sample test results.

[0026] 3. The linear guide rail and slider design allow the cleaning tank to move smoothly along a predetermined path, ensuring effective coverage of the area below the cleaning nozzle, thus achieving comprehensive and efficient cleaning. Simultaneously, the drive mechanism, consisting of a lead screw and a stepper motor, precisely controls the movement position and speed of the cleaning tank, improving the automation and accuracy of the cleaning process, and further enhancing the accuracy and efficiency of spectral detection.

[0034] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0035] This application discloses a rapid cleaning module.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A rapid cleaning module includes an experimental platform 1, a rotating test tube tray 2, a Z-axis module 3, a liquid injection gun 4, and an electronic control module 5. The electronic control module 5 is fixedly mounted on the side wall of the experimental platform 1. The rotating test tube tray 2 is controlled by the electronic control module 5 and is coaxially rotatable within the experimental platform 1. A liquid injection station 11 is provided on the experimental platform 1 to connect with the test tubes on the rotating test tube tray 2. The Z-axis module 3 is located on one side of the liquid injection station 11 and is vertically mounted on the experimental platform 1. The liquid injection gun 4 is mounted on the movable block of the Z-axis module 3 and is connected to an external reagent supply device to inject reagents into the test tubes under the liquid injection station 11. A cleaning tank 6 is provided on the experimental platform 1, sliding towards the liquid injection station 11. A suction port 61 communicating with the inner cavity is opened on the side wall of the cleaning tank 6. A suction pump 12 is fixedly mounted on the experimental platform 1, and a suction pipe 611 connects the suction pump 12 and the suction port 61. The experimental table 1 is also equipped with a dust cover 13 that covers the Z-axis module 3, the injection gun 4 and the cleaning pool 6.

[0037] Reference Figure 1 , Figure 2 and Figure 3 During the experiment, the electronic control module 5 controls the rotation of the rotating test tube tray 2. When the test tubes on the rotating test tube tray 2 that are to be injected with reagents reach the docking injection station 11, the rotation stops. At this time, the moving block on the Z-axis module 3 moves down, thereby causing the mounting base 31 to drive the injection gun 4 into the injection station 11, injecting reagents into the test tubes and then raising it. The above actions are repeated several times to inject reagents into several test tubes on the rotating test tube tray 2. When it is necessary to replace the reagent in the injection gun 4, the electronic control module 5 controls the cleaning tank 6 to slide below the injection gun 4, and then drives the injection gun 4 to be inserted into the cleaning tank 6. At the same time, the external reagent supply device switches the reagent input to the injection gun 4 and flushes a large amount of new solvent to clean the old solvent remaining in the injection gun 4. The pump 12 promptly extracts the cleaning waste liquid from the cleaning tank 6 through the pump pipe 611.

[0038] Reference Figure 2 and Figure 3 A mounting base 31 is fixedly installed on the moving block of the Z-axis module 3. The injection gun 4 includes a gun head 41 and an injection tube 42. The gun head 41 is vertically inserted into the mounting base 31. The two sides of the gun head 41 have integrally formed connecting edges 411. The connecting edges 411 and the mounting base 31 are respectively provided with mounting holes 311. Fixing bolts 312 are inserted into the two mating mounting holes 311. The fixing bolts 312 fix the gun head 41 to the mounting base 31.

[0039] Reference Figure 3 An anti-overflow boss 32 is fixedly provided at the bottom of the mounting base 31. The anti-overflow boss 32 includes a coaxially integrally formed insertion part 321 and a support part 322. The insertion part 321 is located below the support part 322. The outer diameter of the insertion part 321 matches the internal size of the cleaning tank 6, and the insertion part 321 and the cleaning tank 6 are inserted and engaged. The bottom end of the nozzle of the gun head 41 passes through the support part 322 and extends into the insertion part 321. When the insertion part 321 is inserted into the cleaning tank 6, the support part 322 abuts against the side top wall of the cleaning tank 6.

The cleaning tank 6 is installed on the slider 71 by bolts, and the cleaning tank 6 slides along the linear guide rail 7 toward the lower part of the nozzle 41. The experimental platform 1 is provided with a driving component 72 that drives the cleaning tank 6 to slide along the linear guide rail 7. The driving component 72 can be driven by a cylinder, a motor and gear meshing transmission, or a motor and lead screw 721 threaded transmission. In this embodiment, the driving component 72 includes a lead screw 721 and a stepper motor 722. The lead screw 721 is located above the guide rail, parallel to the linear guide rail 7, and rotatably connected to the linear guide rail 7. The lead screw 721 rotates through the slider 71 through the thread. The stepper motor 722 is fixedly installed on the side wall of the linear guide rail 7 away from the injection station 11. Its output shaft rotates through the linear guide rail 7 and is coaxially fixedly connected to the lead screw 721.

[0041] Reference Figure 4 In order to drain the cleaning waste liquid in the cleaning tank 6, a guide channel 62 is provided inside the cleaning tank 6. The liquid extraction port 61 is located at the end of the guide channel 62. The bottom wall of the guide channel 62 is inclined in the direction towards the liquid extraction port 61. A guide slope 63 is also provided between the side top wall of the guide channel 62 and the inner side wall of the cleaning tank 6 to guide the waste liquid to flow into the guide channel 62.

[0042] Reference Figure 2 and Figure 5 To improve cleaning efficiency, a fixed bracket 33 is fixedly installed on the side wall of the moving block of the Z-axis module 3. A heating module 8 for heating the injection pipe 42 is mounted on the fixed bracket 33. The heating module 8 includes a heating block 81 and a heat insulation cover 82 that covers the heating block 81. A threaded groove 811 is provided around the outer wall of the heating block 81. The injection pipe 42 passes between the heating block 81 and the heat insulation cover 82 and is wound around the threaded groove 811. This design effectively increases the heating area of ​​the injection pipe 42, making the temperature of the rinsing liquid inside the injection pipe 42 more uniform, ensuring the cleanliness and consistency of the cleaning effect of the nozzle 41 during the cleaning process. At the same time, the design of the heat insulation cover 82 also reduces heat loss and improves energy utilization efficiency.

[0043] Reference Figure 2 To avoid the problems of tangled and messy pipes, a sorting board 9 is installed on the experimental platform 1. Multiple through holes 91 are distributed vertically along the sorting board 9, and the liquid extraction pipe 611 and the liquid injection pipe 42 correspond one-to-one with the through holes 91. The design of the sorting board 9 allows the liquid extraction pipe 611 and the liquid injection pipe 42 to be arranged neatly.

[0045] The implementation principle of a rapid cleaning module in this application embodiment is as follows: by setting up a sliding cleaning tank 6 and a high-efficiency liquid extraction system, efficient and thorough cleaning is achieved, avoiding cross-contamination and greatly improving the accuracy and reliability of spectral detection. In particular, the design of the anti-overflow boss 32, the guide channel 62, the heating module 8, and the collection plate 9 further enhances the stability of the system and the cleaning effect. These optimized designs not only improve the cleaning speed but also reduce water waste, meeting environmental protection requirements. They are particularly suitable for high-throughput detection environments and can significantly improve work efficiency and detection quality.
