Description

Technical Field

[0001] This utility model relates to the field of gels, specifically to a gel preparation apparatus for mass production of nucleic acid agarose electrophoresis gels. Background Technology

[0002] Nucleic acid agarose gel electrophoresis is a molecular biology technique used to separate, identify, and quantify DNA or RNA fragments. The basic procedure for preparing traditional nucleic acid agarose gels mainly includes: selecting a mold, preparing the gel solution, sol-gel, adding nucleic acid staining agents, pouring the gel, and allowing it to solidify. Although the principle and method of preparation are simple, batch production still faces some challenges in high-throughput and standardized application scenarios (such as clinical diagnosis, gene testing laboratories, and large-scale teaching experiments), as detailed below.

[0003] 1. It is necessary to ensure that the large batch of agarose solution is heated evenly to prevent scorching at the bottom. At the same time, when cooling to the pourable temperature, it is necessary to prevent some of the solution from solidifying prematurely in the mold. 2. All pouring needs to be completed quickly before the solution solidifies; slow operation will cause the solution to solidify in the mold.

[0004] 3. Human intervention: Manual pouring makes it difficult to ensure that the thickness of each piece of adhesive is completely consistent, which affects the reproducibility of results. This is a major obstacle for clinical or quality control applications that require strict standards.

[0005] When demand is low, the above can be accomplished manually by planning the time and preparing enough molds and heating equipment. However, if the demand is too high, it becomes difficult to meet all the above requirements at the same time. As market demand increases, it is urgent to solve the above technical problems. Summary of the Invention

[0006] The problem this invention aims to solve is to propose a gel preparation device for mass production, which addresses the above-mentioned technical issues, eliminates human error, and improves throughput and data reliability.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a gel preparation device for mass production includes a mixing tank for mixing raw materials for preparing gel, and a heating structure for heating the mixing tank is provided below the mixing tank; The mixing tank is connected above to multiple feeding tanks for precise material supply, and is equipped with a feeding pipe for supplying material to the gel mold and / or for discharging cleaning fluid. A toothed comb that moves up and down relative to the top of the gel mold is provided to form sample loading holes on the upper surface of the gel; It also includes cleaning pipes to deliver cleaning media into the mixing tank.

[0008] Furthermore, the mixing drum is tilted and the tilt angle is adjustable, with the tilt angle being θ, where 0 < θ < 50 degrees, and the lower end of the feeding pipe is located at the lower part of the tilted mixing drum.

[0009] Furthermore, it also includes a frame structure for placing multiple gel molds, and the frame is equipped with a drive assembly that drives the comb to move up and down.

[0010] Furthermore, the number of driving components is multiple, matching the number of gel molds. Each driving component includes a servo motor and a lifting frame. The servo motor is vertically positioned and drives the lifting frame to move up and down via a lead screw structure. The carrier is equipped with a first contact switch for detecting the vertical position of the lifting frame. The comb is fixed to the lower end of the lifting frame. The comb and the lifting frame are vertically positioned via a T-slot structure and fixed by a horizontally positioned locating pin.

[0011] Furthermore, the lifting frame is provided with a T-shaped groove, the comb is a symmetrical I-shaped structure with protruding ends at the top and bottom, and the height of the middle of the I-shape matches the vertical thickness of the T-shaped groove. The T-shaped groove has positioning holes on both sides in the vertical direction that cooperate with the positioning pins.

[0012] Furthermore, the T-groove is provided with a wear-resistant strip on the side adjacent to the toothed comb, and the upper end of the lifting frame is provided with multiple adjusting screw holes.

[0013] Furthermore, the drive assembly consists of multiple interconnected components, including a main motor, a main drive shaft, auxiliary drive shafts, and two reducers. The main drive shaft is arranged along the length of the shelf, and the main motor drives the main drive shaft to rotate via a worm gear structure. The main drive shaft drives the auxiliary drive shafts on both sides to rotate via the reducers. The auxiliary drive shafts are arranged along the width of the shelf, forming a symmetrical U-shaped drive system. The auxiliary drive shafts drive the lifting screw to move up and down via a worm gear and lead screw structure. The lower end of the lifting screw is fixedly connected to the lifting plate, and the toothed comb is fixed to the lower end face of the lifting plate.

[0014] Furthermore, it also includes a concentrate tank, a diluent tank, and a cleaning solution tank. The cleaning pipeline connects the cleaning solution tank and the mixing tank. A four-way valve is installed at the end of the cleaning pipeline, which is divided into three pipes evenly distributed at the upper end of the mixing tank. The concentrate tank and the diluent tank deliver materials to the mixing tank through a control pump. It also includes a waste liquid tank for collecting the liquid after the mixing tank is cleaned.

[0015] Furthermore, the mixing tank and the heating structure form an integrated skid-mounted structure with an external protective cover, including a base plate and a rotating plate. The heating structure is mounted on the rotating plate, with one end of the rotating plate hinged to the base plate and the other end fixedly mounted after adjustment through an elongated hole.

[0016] Furthermore, the mixing tank is equipped with a stirring structure, and the lower end of the stirring structure is equipped with stirring blades.

[0017] Compared with the prior art, the advantages and positive effects of this utility model are as follows.

[0018] This application integrates feeding, mixing, heating, heat preservation, and pouring functions into one unit, completing the preparation of multiple gels in one go. This greatly reduces human waiting and operation time, increases throughput, that is, increases the amount of work that can be completed or the number of samples processed per unit time, improves efficiency, and at the same time reduces the impact of human factors on gel preparation, ensuring the consistency of each gel, improving data reliability, and ensuring that the gel data is real, accurate, repeatable, and reliable.

[0019] The combs in this application are symmetrically arranged, allowing for installation from either the top or bottom, thus extending their service life. The T-groove structure facilitates disassembly and enables quick vertical positioning. Simultaneously, the upper adjustment screw hole, containing a screw, allows for fine-tuning of the lower comb at different angles and positions, ensuring the combs are level and guaranteeing consistent sample loading hole specifications.

[0020] 3. This application is for mass production, setting up multiple gel molds to prepare gels simultaneously, and setting different drive components for different batch sizes. The drive components used for medium batches are different from those used for large batches. For medium batches, one gel mold corresponds to one lifting frame controlled by a separate servo motor, and the batch size can be adjusted according to actual needs. For large batches, the drive components adopt a symmetrical U-shaped structure, and multiple lifting plates are driven by the same motor, which has high synchronization and reduces energy consumption.

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] In the gel preparation process, the comb is crucial for successful gel electrophoresis. It is the fundamental guarantee for experimental standardization, reproducible results, and clear band identification. The comb is inserted to create regular and uniform "sample loading wells" in the gel, allowing us to accurately and neatly add samples. The "wells" or "holes" formed by the comb act like a mold, providing each sample with an independent, clearly defined "container," ensuring that the sample is confined in a fixed position. Consistent comb specifications ensure consistency and comparability of sample loading.

[0028] Example 1, such as Figures 1-5 As shown, the gel preparation device for mass production includes a mixing tank 1 for mixing raw materials for gel preparation. A heating structure 8 is provided below the mixing tank 1 for heating it. The heating structure 8 can be an induction cooker, an electric heating pad, or other equivalent heating structure, as long as it can achieve heating. Generally, the temperature required for gel preparation is 50-60 degrees Celsius, which can be achieved by many heating structures. The mixing tank 1 is connected to multiple feeding tanks for precise feeding. Inside, there is a feeding pipe 2 for feeding the gel mold 16 and / or for discharging the cleaning liquid. During the gel preparation process, the feeding pipe 2 is used to transport the gel in a liquid state after mixing and heating. In the cleaning state, the feeding pipe 2 transports the cleaned liquid and then discharges it into the waste liquid tank 9. A toothed comb 5 is provided above the gel mold and moves up and down relative to it. During the gel forming process, the toothed comb 5 moves downward and inserts into the gel. After the gel solidifies, the toothed comb 5 moves upward and is pulled out. Throughout the process, the toothed comb 5 is used to form sample loading holes on the upper surface of the gel. It also includes a cleaning pipe 3, which delivers the cleaning medium into the mixing tank 1. The cleaning pipe 3 connects the cleaning liquid tank 10 and the mixing tank 1. A four-way valve 31 is installed at the end of the cleaning pipe 3, which is divided into three pipes evenly distributed at the top of the mixing tank 1. The spraying is uniform, which helps to improve the cleaning efficiency.

[0029] Preferably, the mixing tank 1 is tilted and the tilt angle is adjustable, with the tilt angle being θ, where 0 < θ < 50 degrees. The lower end of the feeding pipe 2 is located at the lower part of the tilt of the mixing tank 1, which facilitates pumping out, avoids a large amount of residue, saves raw materials, and is convenient for cleaning.

[0030] Preferably, the system also includes a frame structure shelf 7, which is made of steel profiles and can be purchased directly from the market. It is low in cost and high in strength. The shelf 7 is used to place multiple gel molds. The shelf 7 is equipped with a drive assembly 6, which drives the comb 5 to move up and down. More preferably, there are multiple drive assemblies 6, which are matched with the number of gel molds. The drive assembly 6 includes a servo motor 611 and a lifting frame 612. The servo motor 611 is vertically arranged and drives the lifting frame 612 to move up and down through a screw and nut structure. The shelf 7 is equipped with a first contact switch 613 for detecting the up and down position of the lifting frame 612. The comb 5 is fixed to the lower end of the lifting frame 612. The comb 5 and the lifting frame 612 are vertically positioned by a T-slot 6121 structure and fixed by a horizontally arranged positioning pin. The structure is simple and easy to disassemble and fix.

[0031] Preferably, the lifting frame 612 is provided with a T-shaped groove 6121, and the toothed comb 5 is a symmetrical I-shaped structure with protruding ends at the top and bottom. The height of the middle of the I-shape matches the vertical thickness of the T-shaped groove 6121. The two sides of the T-shaped groove 6121 in the vertical direction are provided with positioning holes 6122 that cooperate with positioning pins, enabling quick up and down positioning and side positioning with high precision. More preferably, the side of the T-shaped groove 6121 adjacent to the toothed comb 5 is provided with a wear-resistant strip 6124 to avoid tooth wear. More preferably, the upper end of the lifting frame 612 is provided with multiple adjusting screw holes 6123, with matching screws or bolts inside. The horizontal action of the toothed comb 5 from the top is adjusted by adjusting the downward pressure at multiple points to achieve the adjustment of the levelness, thus ensuring that the specifications of the sample holes formed are consistent.

[0032] More preferably, the upper end of the shelf 7 is provided with a support plate 71 fixed by screws. The position of the support plate 71 is confirmed by a second contact switch 72. The gel mold is embedded in the inner groove of the support plate 71. The position of the gel mold is confirmed by a third contact switch 73. The entire structure realizes detection and precise positioning.

[0033] Preferably, the mixture also includes a concentrate tank 11, a diluent tank 12, and a cleaning liquid tank 10. The concentrate tank 11 and the diluent tank 12 deliver materials to the mixing tank 1 via a control pump. The control pump can precisely control the pumped dosage to ensure the accuracy of mixing. More preferably, this application also includes a waste liquid tank 9 for collecting the liquid after cleaning the mixing tank 1. This integrates multiple functions such as mixing, preparation, and cleaning into one unit, with a high degree of automation, precise control at each step, reduced influence of human factors, and improved accuracy and consistency.

[0034] Preferably, the mixing tank 1 and the heating structure form an integrated skid-mounted structure and are provided with an external protective cover 102. Ventilation holes are provided on the top of the protective cover 102 to facilitate heat dissipation. The integrated skid-mounted structure includes a base plate 101 and a rotating plate. The base plate 101 serves as the carrier of the skid-mounted structure and is used to install and fix other components. The heating structure is set on the rotating plate to facilitate integrated adjustment with the rotating body. One end of the rotating plate is hinged to the base plate 101, and the other end is fixed after adjustment through the elongated hole 104. There can be multiple elongated holes 104, or a single large-sized elongated hole 104, to facilitate adjustment of the angle and fixation.

[0035] Preferably, the mixing tank 1 is provided with a stirring structure 15, and the lower end of the stirring structure 15 is provided with stirring blades. The stirring structure can adopt a common structure on the market. The motor drives the stirring rod to rotate, and the stirring blades are set at the lower end of the stirring rod to improve the mixing efficiency. In this application, the form of concentrated liquid and diluted liquid is used. Under the heating state, the purpose of uniform mixing can be achieved without stirring. Depending on the specifications, the higher the concentration of gel, the more time is saved by stirring.

[0036] Example 2: Figure 6 As shown, unlike Embodiment 1, for mass production, the drive assembly 6 is a multi-unit linkage assembly, including a main motor 621, a main drive shaft 622, an auxiliary drive shaft 623, and two reducers 624. The main drive shaft 622 is arranged along the length of the rack 7. The main motor 621 drives the main drive shaft 622 to rotate through a worm gear structure. The main drive shaft 622 drives the auxiliary drive shafts 623 on both sides to rotate through the reducers 624. The auxiliary drive shafts 623 are arranged along the width of the rack 7, forming a symmetrical U-shaped drive system. The auxiliary drive shafts 623 drive the lifting screw 625 to move up and down through a worm gear and lead screw structure. The lower end of the lifting screw 625 is fixedly connected to the lifting plate 626. The comb 5 is fixed to the lower end face of the lifting plate 626. Multiple lifting plates 626 can be arranged in parallel. These multiple lifting plates 626 arranged in parallel vertically are connected as one unit on the side of the rack 7 via connecting and fixing plates 627, enabling synchronous vertical movement of multiple lifting plates 626. Moreover, the entire drive assembly 6 uses the same motor, saving energy and achieving high synchronization. In the entire structure, the reducer 624 plays a role in reversing, realizing the transmission of 90-degree power, which is the basis of the U-shaped drive system. At the same time, long-distance power transmission is achieved through worm gear transmission, or horizontal power transmission and steering are achieved through worm gears. Vertical movement is achieved through a screw and nut structure. When converting to the remaining vertical movement of the lifting plates 626, the worm gear, with its inner ring set as a screw nut structure, transmits power in the horizontal direction, thereby driving the lifting screw 625.

[0037] For mass production, when injecting gel into the gel mold, the feeding pipe 2 can be distributed to multiple grouting pumps for simultaneous pouring. The lifting plate 626 is provided with multiple avoidance holes, which are used to allow the grouting pumps to avoid the lifting plate 626 when injecting grout into the gel mold.

[0038] Multiple molds, multiple grouting pumps, and multiple lifting plates 626 work together to achieve mass production.

[0039] During gel preparation, when inserting the comb 5, please pay attention to the following issues: Timing of insertion: Insertion must be made after the gel solution has been poured into the mold but before it has completely solidified. For agarose gel, insertion should be made when the solution has cooled to the point where it is not hot to the touch (about 50-60°C) and appears cloudy.

[0040] Insertion depth: The tips of the comb teeth should maintain a small gap (approximately 0.5-1.0 mm) from the bottom of the mold. Never insert it directly into the bottom of the mold; otherwise, after the gel solidifies, the bottom of the sample loading hole will be very thin, making it prone to cracking when the comb is removed, causing the sample to leak out from the bottom.

[0041] Verticality: The comb must be perpendicular to the gel surface to create wells that are the same width vertically and parallel horizontally. A tilted comb will cause the wells to be skewed, resulting in skewed strips.

[0042] Avoid air bubbles: When inserting the comb, move smoothly to prevent air bubbles from being carried under the tips of the teeth, otherwise the bottom of the sample loading hole will be damaged.

[0043] When to pull the comb out: Wait until the gel has completely hardened (it feels elastic and cool to the touch) before gently pulling the comb out. Pulling it out too early will damage the structure of the holes. When pulling the comb out, pull it vertically upwards, slowly and steadily.

[0044] When preparing the gel, adjust the angle of the rotating plate according to the required gel specifications. The higher the concentration, the larger the angle of the rotating plate (i.e., the greater the tilt). This ensures the plate is tilted to one side, facilitating liquid concentration at the bottom and maximizing pumping out the liquid while avoiding excessive residue that would be difficult to clean. After determining the rotating plate angle, fix the heating device. Determine the ratio of concentrated to diluted solution, and then use a control pump to inject the solution into mixing tank 1 at the set volume for mixing. Simultaneously, heat the mixture using the heating device below to bring it to a molten state. The control pump then pumps the solution into the gel mold through the feed pipe 2, which is fixed to a slide rail by a support frame. The slide rail is suspended from the load... The material on the shelf 7 moves horizontally via a motor screw structure to meet the needs of large-range grouting. At the same time, the feeding pipe 2 can move up and down in the vertical direction via a cylinder to adjust the grouting height. The feeding pipe 2 can be a flexible hose or a telescopic hose to meet the needs of transmission, movement and bending. During the grouting process, the toothed comb 5 descends and inserts into the gel according to the time requirement. After waiting, the toothed comb 5 rises and detaches from the gel, and the preparation is completed. After the raw materials in the mixing tank 1 are used up, the cleaning liquid tank 10 injects liquid into the mixing tank 1 through the cleaning pipe 3 for cleaning, and then pumps it into the waste pool. One cycle is completed. When changing to other specifications of gel or preparing again, the above actions are repeated.

[0045] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
