Description

Technical Field

[0001] This utility model relates to the field of biomedical laboratory equipment technology, and in particular to a multi-component liquid distribution system. Background Technology

[0002] Currently, most biopharmaceutical laboratories or production workshops rely on manual addition of reagents one by one when preparing multi-component reagents. When preparing large quantities and requiring numerous repetitions, this repeated manual addition is prone to errors, is labor-intensive, and compromises product formulation confidentiality. Therefore, given the rapid development of artificial intelligence, it is worth considering developing a multi-component reagent preparation system to replace most manual operations, minimize human error, and maximize product formulation confidentiality and reagent preparation accuracy. Utility Model Content

[0003] This invention provides a multi-component liquid dispensing system that, through the cooperation of a peristaltic pump module, a precision balance, a barcode scanner, and supporting software, achieves automatic liquid addition and quantitative dispensing, avoiding missed or duplicate additions. It eliminates the need for manual liquid addition and weighing by preparation personnel, replacing most manual operations, reducing the workload of staff, minimizing human error, and ensuring the fully automated process avoids manual contact with reagents, thus improving the confidentiality of product formulations and the accuracy of reagent preparation. The peristaltic pump tubing slides along the side Z-shaped slide rail to adjust its position as the upper tubing rack moves. When changing other component raw materials, the upper tubing rack moves along the side Z-shaped slide rail to quickly complete the replacement operation of the peristaltic pump tubing, further improving work efficiency compared to traditional disassembly methods.

[0004] This utility model provides a multi-component liquid distribution system, comprising a solution delivery system (main base, peristaltic pump module, and upper tube rack), a metering system (precision balance), an error prevention system (barcode scanner), and supporting software. The barcode scanner uses existing equipment, specifically model 1902GSR. The solution delivery system includes a main base, a peristaltic pump module, and an upper tube rack. The peristaltic pump module is fixedly connected to the top of the main base, and the upper tube rack is positioned above the peristaltic pump module. A precision balance is mounted on the upper part of the main base. A side Z-shaped chute is symmetrically fixedly connected to the top of the main base. The horizontal section of the Z-shaped structure of the side Z-shaped chute is 30mm long, and the vertical section is 4mm high. 0mm, providing sliding guidance for the upper tube rack. The middle of the side Z-shaped slide rail is fixedly connected to the upper connecting bracket. The upper end of the upper connecting bracket is slidably connected to the positioning column. The positioning column and the upper connecting bracket are fixedly connected to the middle support spring. The middle support spring is made of stainless steel spring with an elastic coefficient of 20N / mm and a preload of 5N. It provides buffer when the upper tube rack slides down and assists the positioning column in accurately engaging with the side slot. The middle of the main base is fixedly connected to the tube rack. The middle of the main base is fixedly connected to the liquid collection box. The liquid collection box is a rectangular box with an open top. It is made of chemically resistant PP material and is used to collect the liquid remaining inside after the peristaltic pump tube is replaced after the liquid separation is completed.

[0005] Furthermore, the tube support and the liquid collection box are both located between the precision balance and the side Z-shaped slide frame. The precision balance is connected to the control system of the peristaltic pump module and controls the start and stop of the rotor in real time according to the preset weight, thereby realizing the accurate separation of multi-component reagents. The side Z-shaped slide frame is located on both sides of the peristaltic pump module. The upper tube support moves along the side Z-shaped slide frame to quickly complete the replacement operation of the peristaltic pump tube.

[0006] Furthermore, a guide groove is fixedly provided on the front side of the peristaltic pump module. The motor of the peristaltic pump module is fixedly connected to the main reducer shaft and the rotor. The rotor speed range is 0-300 r / min. A roller slide frame is slidably connected in a ring array on the outer side of the rotor. A rear connecting slide column is fixedly connected to the side of the roller slide frame. An outer roller is rotatably connected to the top of the roller slide frame. When the rotor rotates, the rear connecting slide column on the roller slide frame generates a reciprocating motion along the radial direction of the rotor under the constraint of the guide groove. The outer roller moves synchronously with the roller slide frame.

[0007] Furthermore, the rear connecting slide column and the guide slide groove are slidably connected. The guide slide groove is an arc-shaped groove structure with a depth of 8mm, a width of 10mm, and a vertical height difference of 15mm between the upper and lower sides. It is used to guide the rear connecting slide column to achieve regular reciprocating motion. The rear connecting slide column on the upper side of the guide slide groove is further away from the rotor than the rear connecting slide column on the lower side of the guide slide groove. The moving radius of the outer roller increases, and the squeezing force of the outer roller on the peristaltic pump tube increases.

[0008] Furthermore, the upper tube frame is fixedly connected to the middle and both sides with hose fixing brackets. The hose fixing brackets are fixedly connected to the sides with side connecting springs. The side connecting springs are compression springs with an elastic coefficient of 15N / mm and a preload of 3N to ensure that the peristaltic pump tube and the rotor are tightly fitted. The hose fixing brackets are rotatably connected to both sides with elastic pressure arms. The lower part of the elastic pressure arms is fixedly connected to a roller mounting bracket. The lower end of the roller mounting bracket is rotatably connected to a side fixing roller.

[0009] Furthermore, the lower ends of the elastic pressure arm and the side connecting spring are fixedly connected, and the bottom of the upper tube frame is fitted with a peristaltic pump tube. The peristaltic pump tube is made of food-grade silicone material, with an inner diameter of 4mm and a wall thickness of 1mm. Side connecting sliding columns are fixedly connected to both sides of the upper tube frame, and the top of the hose fixing brackets on both sides of the upper tube frame is recessed with side slots.

[0010] Furthermore, the elastic pressure arms and roller mounting brackets on both sides of the hose fixing bracket are located on both sides of the peristaltic pump tube, and the side fixing rollers are symmetrically clamped on both sides of the peristaltic pump tube.

[0011] Furthermore, the side connecting slide column and the side Z-shaped slide frame are slidably connected. When the side slot and the positioning column are engaged, the upper tube frame where the side slot is located is vertically above the rotor. The positioning column and the side slot are engaged to fix the position of the upper tube frame.

[0012] The multi-component liquid distribution system provided by this utility model has the following beneficial effects:

[0013] By combining a peristaltic pump module, a precision balance, a barcode scanner, and accompanying software, the system achieves automated liquid addition and quantitative control, avoiding the omissions and duplicates that are easily caused by manual liquid addition by preparation personnel. It replaces most manual operations, reduces the workload of preparation personnel, minimizes human error, and the fully automated process avoids manual contact with liquid reagents, improving the preservation of product formulas and the accuracy of reagent preparation.

[0014] The rotor drives the outer roller to rotate circumferentially to squeeze the peristaltic pump tube to add liquid. When the connecting slide column moves above the guide slide, the moving radius of the outer roller increases, the squeezing force of the outer roller on the peristaltic pump tube increases, and the liquid delivery flow rate increases. When the connecting slide column moves below the guide slide, the moving radius of the outer roller decreases, reducing the height of the lower part of the peristaltic pump module and further reducing the space occupied by the peristaltic pump module.

[0015] The peristaltic pump tube slides along the side Z-shaped slide frame to adjust its position as the upper tube rack moves. When changing other component raw materials, the upper tube rack moves along the side Z-shaped slide frame to quickly complete the replacement operation of the peristaltic pump tube. Compared with the traditional disassembly method, the efficiency is improved by 80%, the waiting time for peristaltic pump tube replacement is shortened, and the preparation efficiency is further improved. The peristaltic pump tube is positioned by the synchronous clamping of the side fixed rollers, and the side slot and positioning post are engaged to realize the alignment of the peristaltic pump tube and the rotor, ensuring that it can be put into use without secondary calibration after tube replacement.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Example 1: Please refer to... Figures 1 to 8 :

[0033] The multi-component liquid distribution system proposed in this utility model consists of a solution delivery system (main base 1, peristaltic pump module 2, and upper tube rack 3), a quantitative system (precision balance 101), an error prevention system (barcode scanner), and supporting software. The barcode scanner uses existing equipment, model 1902GSR. The solution delivery system includes the main base 1, peristaltic pump module 2, and upper tube rack 3. A precision balance 101 is mounted on the upper part of the main base 1. A side Z-shaped slide rail 102 is symmetrically fixedly connected to the top of the main base 1. The horizontal section of the Z-shaped structure of the side Z-shaped slide rail 102 is 30mm long, and the vertical section is 40mm high, providing sliding guidance for the upper tube rack 3. A [missing information - likely a component or component] is fixedly connected to the middle of the side Z-shaped slide rail 102. The upper connecting bracket 103 has a slidable positioning post 105 at its upper end. A middle support spring 104 is fixedly connected between the positioning post 105 and the upper connecting bracket 103. The middle support spring 104 is made of stainless steel with an elastic coefficient of 20N / mm and a preload of 5N. It provides cushioning when the upper tube rack 3 slides down and assists the positioning post 105 in accurately engaging with the side slot 308. A tube support 106 is fixedly connected to the middle of the main base 1, and a liquid collection box 107 is also fixedly connected to the middle of the main base 1. The liquid collection box 107 is a rectangular box with an open top, made of chemically resistant PP material. It is used to collect the residual liquid inside the peristaltic pump tube 306 after the liquid separation is completed, thus preventing contamination of the liquid. The precision balance 101 and main base 1, along with the tube support 106 and collection box 107, are all positioned between the precision balance 101 and the side Z-shaped slide frame 102. The precision balance 101 is communicatively connected to the control system of the peristaltic pump module 2, controlling the start and stop of the rotor 202 in real time according to the preset weight, thereby achieving precise dispensing of multi-component reagents. The side Z-shaped slide frame 102 is located on both sides of the peristaltic pump module 2. The upper tube support 3 moves along the side Z-shaped slide frame 102 to quickly complete the replacement operation of the peristaltic pump tube 306, improving efficiency by 80% compared to the traditional disassembly method, shortening the waiting time for replacing the peristaltic pump tube 306, and further improving preparation efficiency. The peristaltic pump module 2 is fixedly connected to the top of the main base 1. A guide groove 201 is fixedly provided on the front side of the peristaltic pump module 2. The motor connecting the main reducer shaft and the rotor 202 are fixedly connected. The rotation speed of the rotor 202 is 0-300 r / min. A roller sliding frame 203 is slidably connected to the outer side of the rotor 202 in a ring array. A rear connecting slide column 204 is fixedly connected to the side of the roller sliding frame 203. An outer roller 205 is rotatably connected to the top of the roller sliding frame 203. When the rotor 202 rotates, the rear connecting slide column 204 on the roller sliding frame 203 generates a reciprocating motion along the radial direction of the rotor 202 under the constraint of the guide groove 201. The outer roller 205 moves synchronously with the roller sliding frame 203 to periodically squeeze the peristaltic pump tube 306.

[0034] A top tube rack 3 is provided above the peristaltic pump module 2. A hose fixing bracket 301 is fixedly connected to the middle and both sides of the top tube rack 3. Side connecting springs 302 are fixedly connected to both sides of the hose fixing bracket 301. The side connecting springs 302 are compression springs with an elastic coefficient of 15 N / mm and a preload of 3 N, ensuring a tight fit between the peristaltic pump tube 306 and the rotor 202. Elastic pressure arms 303 are rotatably connected to both sides of the hose fixing bracket 301. A roller mounting bracket 304 is fixedly connected to the lower part of the elastic pressure arm 303. A side fixing roller 305 is rotatably connected to the lower end of the roller mounting bracket 304. The elastic pressure arm 303 and the side... The lower end of the connecting spring 302 is fixedly connected, and the bottom of the upper tube frame 3 is attached to the peristaltic pump tube 306. The peristaltic pump tube 306 is made of food-grade silicone material with an inner diameter of 4mm and a wall thickness of 1mm. Side connecting slide columns 307 are fixedly connected to both sides of the upper tube frame 3. The top of the hose fixing brackets 301 on both sides of the upper tube frame 3 is recessed with side slots 308. The elastic pressure arms 303 and roller mounting brackets 304 on both sides of the hose fixing brackets 301 are located on both sides of the peristaltic pump tube 306. The side fixing rollers 305 are symmetrically clamped on both sides of the peristaltic pump tube 306. The positioning and position fixing work is achieved by the synchronous clamping of the peristaltic pump tube 306 by the side fixing rollers 305.

[0035] In this embodiment, the rear connecting slide column 204 and the guide slide groove 201 are slidably connected. The guide slide groove 201 is an arc-shaped groove structure with a depth of 8mm, a width of 10mm, and a vertical height difference of 15mm between the upper and lower sides. It is used to guide the rear connecting slide column 204 to achieve regular reciprocating motion. The rear connecting slide column 204 on the upper side of the guide slide groove 201 is further away from the rotor 202 than the rear connecting slide column 204 on the lower side of the guide slide groove 201. The moving radius of the outer roller 205 is increased, the squeezing force of the outer roller 205 on the peristaltic pump tube 306 is increased, the liquid delivery flow rate is increased by 60%, and the single liquid addition time is shortened to 1 / 3 of that of a traditional peristaltic pump.

[0036] In this embodiment, the side connecting slide column 307 and the side Z-shaped slide frame 102 are slidably connected. When the side slot 308 and the positioning column 105 are engaged, the upper tube frame 3 where the side slot 308 is located is vertically above the rotor 202. The positioning column 105 and the side slot 308 are engaged to fix the position of the upper tube frame 3, thereby achieving the alignment of the peristaltic pump tube 306 and the rotor 202, ensuring that it can be put into use without secondary calibration after tube replacement.

[0037] In this second embodiment, based on the first embodiment, an electric telescopic rod is installed on the tube support 106. The lower end of the electric telescopic rod is connected to a U-shaped pressure rod. The telescopic rod is driven by the control system to move the pressure rod downward, thereby quickly squeezing and blocking the peristaltic pump tube 306 and quickly stopping the integrated flow of the peristaltic pump tube 306. This allows for a faster active cessation of the liquid flow in the peristaltic pump tube 306. Multiple precision balances 101 are installed on a motor-driven disc. Each precision balance 101 weighs one formula at its top, enabling the peristaltic pump module 2 to replenish multiple different formulas at once, further accelerating the preparation efficiency of reagents with different components.

[0038] The working principle of this utility model is as follows: When a liquid separation operation is required, a high-precision peristaltic pump driven by a PLC+485 communication system completes the repeated preparation of multi-component reagents according to a set program. Using a combination of a high-precision peristaltic pump, a high-precision balance + RS232 interface, a PLC+485 communication system, and a WINDOWS industrial control computer, each component is distributed multiple times by the peristaltic pump. After each distribution, the software automatically calculates the distribution coefficient based on the measurement value of the high-precision balance 101. The distribution coefficient is calibrated based on the remaining sample value. Multiple distribution calibrations ensure that the final sample volume is within the allowable error range of the target value. A barcode scanner is connected to the WINDOWS industrial control computer via a USB interface as a controller and supporting software. The controller compares the barcode with the internal formula data. With the cooperation of the barcode scanner and supporting software, the barcode scanner scans the barcode on the collection bottle to switch and identify the sample addition of different collection bottles or different component reagents, preventing missed or duplicate additions. The repeated preparation of multi-component reagents is completed according to the program set by the supporting software, avoiding human error.

[0039] Place the reagent bottle on the precision balance 101. Once the barcode on the reagent bottle is successfully scanned, liquid addition begins. The industrial control computer stores different formulas. The upper tube rack 3 slides down the side Z-shaped slide rail 102 via the side connecting slide column 307. The positioning column 105 and the side slot 308 engage to fix the position. The upper tube rack 3 presses down on the peristaltic pump tube 306, causing it to fit against the outer roller 205. The first end of the peristaltic pump tube 306 is fixed above the reagent bottle, and the second end is sealed to the Teflon tube of the raw material bottle via a threaded interface. Correctly connect the communication lines between the precision balance 101 and the controller, and between the barcode scanner and the controller. Turn on the power and the power switch on the back. The controller and precision balance 101 will start, and the accompanying software will automatically select the formula. Check the order and amount of sample addition to ensure correct production settings. Turn on the pump start button on the front of the instrument. The pump starts, and the motor of the peristaltic pump module 2 drives the rotor 202 to rotate. The rear connecting slide column 204 on the roller sliding frame 203 slides along the guide slide groove 201, causing the outer roller 205 to periodically squeeze the peristaltic pump tube 306. When the rotor 202 rotates, the rear connecting slide column 204 on the roller sliding frame 203, under the constraint of the guide slide groove 201, generates a reciprocating motion along the radial direction of the rotor 202. The outer roller 205 moves synchronously with the roller sliding frame 203, periodically squeezing the peristaltic pump tube 306. The squeezing frequency is proportional to the rotor speed 202, and the squeezing stroke is determined by the height difference of the guide slide groove 201, thereby achieving stable operation. The fluid transport system delivers reagents to a container above the precision balance 101. The precision balance 101 monitors the weight in real time and feeds the data back to the control system. When the preset weight is reached, the motor stops rotating, completing one dispensing operation. The precision balance 101, peristaltic pump module 2, barcode scanner, and accompanying software work together to achieve weighing and automatic liquid addition, eliminating manual liquid addition and weighing, reducing the workload of personnel, replacing most manual operations, minimizing human error, and ensuring the fully automated process avoids manual contact with reagents, improving the confidentiality of technical formulas and the accuracy of reagent preparation. The precision balance 101 monitors the container weight in real time with a high precision of 0.01g and feeds the data back to the control system for comparison with preset formula parameters. In contrast, when the weight is below target, the system automatically drives the peristaltic pump module 2 to operate. The rotor 202 drives the outer roller 205 to move along the guide groove 201, periodically squeezing the peristaltic pump tube 306 to achieve precise liquid addition at the micro-level of ±5μL. When the target weight is reached, the system triggers the pump to stop within 0.1 seconds. Compared with traditional manual operation, the weighing error is reduced from ±3% to ±0.3%, and the reagent preparation accuracy is improved by more than 90%. The fully automated process avoids manual contact with reagents, effectively ensuring the confidentiality of the technical formula. The final sample addition of each component is within the allowable error range of the target value: above 100g, error ≤0.2%; 50-100g, error ≤0.4%; 30-50g, error ≤0.8%; and 10-30g, error ≤1%.2% accuracy; repeated preparation avoids missing or duplicate component additions; stable operating speed: can complete 25 repeated preparations of 8 components with dosages between 10 and 500g within 4 hours, including component switching time; the system automatically records all process data and can generate and export reports in the required format; three-level access control ensures maximum confidentiality of the technical formula; the rotor 202 drives the outer roller 205 to rotate circumferentially, squeezing the peristaltic pump tube 306 for liquid addition. When the connecting slide column 204 moves above the guide slide 201, the moving radius of the outer roller 205 increases, the squeezing force of the outer roller 205 on the peristaltic pump tube 306 increases, the liquid delivery flow rate increases by 60%, and the single liquid addition time is shortened to 1 / 3 of that of a traditional peristaltic pump. When the connecting slide column 204 moves below the guide slide 201, the moving radius of the outer roller 205 decreases, the lower height of the pump body decreases by 20mm, the overall structural compactness increases by 35%, and the lower height of the peristaltic pump module 2 is reduced, further reducing the space occupied by the peristaltic pump module 2.

[0040] Multiple sets of peristaltic pump tubes 306 and the upper tube rack 3 slide along the side Z-shaped slide frame 102 to adjust their positions. When changing other component raw materials, the upper tube rack 3 moves along the side Z-shaped slide frame 102 to quickly complete the replacement operation of the peristaltic pump tubes 306. Compared with the traditional disassembly method, the efficiency is improved by 80%, the waiting time for replacing the peristaltic pump tubes 306 is shortened, and the preparation efficiency is further improved. The peristaltic pump tubes 306 are positioned by the synchronous clamping of the side fixing rollers 305, and the side slots 308 and positioning posts 105 engage to achieve the alignment of the peristaltic pump tubes 306 and the rotor 202, ensuring that no secondary calibration is required after tube replacement before use. Using this system, the multi-component reagent preparation cycle is shortened from 45 minutes to 12 minutes. It can complete 25 repeated preparations of 8 components with dosages ranging from 10 to 500g within 4 hours, including component switching time. The daily processing capacity is increased by 2.8 times, meeting the needs of high-throughput experiments. After all reagent bottles are dispensed, click "Generate Data" on the controller. The controller system will save the production record on the desktop. Please copy the data and back it up in time. Turn off the system, turn off the pump, and turn off the power. The instrument is powered off. The preparation is complete and the instrument is used up. Remove the peristaltic pump tube 306 and fill in the "Multi-component Liquid Dispensing System Usage Record".
