[0002] Liquid separation equipment is an automated liquid handling platform widely used in biological, chemical, pharmaceutical and testing laboratories.

[0003] Currently, most automated liquid dispensing devices adopt a "single peristaltic pump with multi-channel dispensing head" solution, which uses a high-flow peristaltic pump to push liquid to an 8-channel or 16-channel metal dispensing strip and uses solenoid valves to control the opening and closing of each channel.

[0004] However, this approach has significant limitations. The system struggles to process different reagents in the same round, making it difficult to achieve truly simultaneous dispensing of multiple liquids. These issues not only increase the complexity of the operation process but also limit the improvement of dispensing efficiency. Utility Model Content

[0022] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0023] This application discloses a multi-pump high-speed liquid separation device.

[0024] A multi-pump high-speed liquid dispensing device includes a mounting base 1, a support tray 2, a spraying assembly 3, and a pump system 4. The mounting base 1 is fixedly installed at a predetermined position, and the support tray 2, spraying assembly 3, and pump system 4 are all mounted on the base. The support tray 2 is located at the bottom of the side wall of the mounting base 1, and its top surface is used to place an orifice plate. The spraying assembly 3 is mounted on the side wall of the mounting base 1 and above the tray; this assembly is connected to a delivery hose, and the pump system 4 is connected to the delivery hose.

[0025] During the liquid separation operation, the inlet end of the infusion tubing is placed into a container containing the target liquid. The liquid is then pumped to the injection assembly 3 by the pump system 4, and the injection assembly 3 accurately injects the liquid into each hole of the orifice plate, thereby completing the separation process.

[0026] The supporting pallet 2 is a long, strip-shaped plate structure, arranged horizontally, with its long side adjacent to the mounting base 1. The top edge of the pallet is equipped with a guardrail 23 to prevent the perforated plate from slipping during placement or movement.

[0027] The carrying tray 2 is connected to a horizontal moving mechanism 5, which can move along its length, thereby moving the orifice plate placed on it together, so that the orifice plate is accurately positioned directly below the injection assembly 3, which facilitates precise liquid injection.

[0028] The top surface of the support tray 2 is provided with several spacers 21 along its length, and the extension direction of the spacers 21 is consistent with the width direction of the tray. A limiting groove 22 is formed between adjacent spacers 21 to clamp and fix the orifice plate, reducing the possibility of the orifice plate shifting when the tray moves, thereby improving the positional accuracy of the liquid injection.

[0029] The horizontal moving mechanism 5 includes a fixed base 51, a transmission belt 52, a drive motor 53, a linear guide rail 54, and a load-bearing connecting plate 55. The fixed base 51 includes a main frame 511 and an auxiliary frame 5111, both of which are fixedly mounted on the base plate 11 of the mounting frame 1. The main frame 511 has a pair, each with a linear guide wheel 512 mounted on it, and the transmission belt 52 is tensioned between the two linear guide wheels 512. The drive motor 53 is fixed to the base plate 11 of the mounting frame 1 near the transmission belt 52, and its output shaft is connected to the transmission belt 52, driving the transmission belt 52 to move. The linear guide wheels 512 provide belt drive and tensioning.

[0030] The inner surface of the transmission belt 52 is provided with a toothed structure. The drive wheel on the output shaft of the drive motor 53 and the linear guide wheel 512 are both machined with matching toothed shapes. Through tooth meshing transmission, slippage is avoided and the precise movement position of the transmission belt 52 is ensured.

[0031] Linear guide rail 54 is fixed to auxiliary frame 5111, and its extension direction is consistent with the length direction of the pallet. Linear slider 541 is mounted on linear guide rail 54, and linear slider 541 can slide along linear guide rail 54. Bearing connecting plate 55 is Z-shaped, with one end fixed to transmission belt 52 by screw assembly, and the other end connected to the bottom of bearing pallet 2. The side of bearing connecting plate 55 is fixed to linear slider 541.

[0032] When the transmission belt 52 moves, it drives the load-bearing connecting plate 55 to move, which in turn pushes the tray and the perforated plate on it to move together. During this process, the linear guide rail 54 and the linear slider 541 provide support and guidance for the load-bearing connecting plate 55, further improving the smoothness of movement and positioning accuracy.

[0033] The injection assembly 3 is equipped with a vertical adjustment mechanism 6 and a horizontal adjustment mechanism 7, which can respectively move towards or away from the tray in the vertical direction and in the horizontal plane. Through the coordinated operation of the two mechanisms, the relative position of the injection assembly 3 and the orifice plate can be flexibly adjusted, improving the convenience and adaptability of the injection operation.

[0034] The vertical adjustment mechanism 6 includes a vertical mounting plate 61, a vertical guide rail 62, a vertical slider 63, a lifting belt 64, a lifting motor 65, and a lifting platform 66. The vertical mounting plate 61 is fixedly mounted on the base plate 11 of the mounting frame 1, the vertical guide rail 62 is mounted on the side of the plate, and the vertical slider 63 is assembled on the vertical guide rail 62 and can slide up and down along it.

[0035] A pair of lifting guide wheels 611 are mounted on the side of the vertical mounting plate 61, and the lifting belt 64 is wound around the two wheels. The lifting motor 65 is fixed to the side of the vertical mounting plate 61, and its output shaft is connected to one of the lifting guide wheels 611, which can drive the lifting belt 64 to move.

[0036] The lifting platform 66 is fixedly connected to the vertical slider 63 and connected to the lifting belt 64 via bolt assemblies. When the lifting motor 65 drives the lifting belt 64 to move, it causes the lifting platform 66 to move vertically. The vertical guide rail 62 and the slider provide guidance and support.

[0037] The horizontal adjustment mechanism 7 includes a vertical plate 71, a horizontal guide rail 72, a horizontal slider 73, a horizontal conveyor belt 74, a horizontal motor 75, and a moving beam 76. The vertical plate 71 is vertically fixed to the lifting platform 66, and the horizontal guide rail 72 is mounted on the surface of the lifting platform 66, with its extension direction perpendicular to the length direction of the pallet. The horizontal slider 73 is assembled on the horizontal guide rail 72 and can slide along the horizontal guide rail 72.

[0038] The vertical plate 71 is equipped with multiple horizontal guide wheels 711 on its side. The transverse motor 75 is fixed to the top of the lifting platform 66, and a pulley is mounted on its output shaft. The transverse belt 74 passes around the pulley and each horizontal guide wheel 711 to form a transmission circuit. The transverse motor 75 drives the transverse belt 74 to move through the pulley.

[0039] The movable crossbeam 76 is fixed to the transverse slider 73, and its extension direction is consistent with that of the transverse guide rail 72. It is connected to the transverse conveyor belt 74 by fasteners. When the transverse conveyor belt 74 moves, it drives the movable crossbeam 76 to move, and the transverse guide rail 72 and the slider play a guiding role.

[0040] The injection assembly 3 is installed at one end of the moving crossbeam 76 near the pallet, and is precisely positioned by both vertical and horizontal adjustment mechanisms.

[0041] The injection assembly 3 includes a fixed plate 31, a distribution bar 32, and nozzles 33. The fixed plate 31 is mounted on the end of the movable crossbeam 76, and the distribution bar 32 is horizontally fixed to the side of the fixed plate 31. The distribution bar 32 has multiple through-holes 321 along its length, and a nozzle 33 is installed at each through-hole 321. Each nozzle 33 corresponds to a row of holes in the orifice plate.

[0042] The pump system 4 includes multiple peristaltic pumps, which are fixedly mounted on the mounting base 1. Each peristaltic pump is connected to a nozzle 33 via a delivery hose, enabling independent control of each nozzle 33. This allows for the simultaneous dispensing of multiple different liquids, improving the flexibility and versatility of the equipment.

[0043] The implementation principle of a multi-pump high-speed liquid dispensing device according to an embodiment of this application is as follows: First, the inlet end of the container containing the target liquid is connected to the infusion hose. Then, the orifice plate is placed into the limiting groove 22 formed by adjacent spacers 21 on the top surface of the support tray 2, and the guardrail 23 prevents the orifice plate from slipping. The drive motor 53 of the horizontal moving mechanism 5 drives the support connecting plate 55 through the toothed transmission belt 52, so that the support tray 2 moves precisely along the linear guide rail 54, and the orifice plates are delivered row by row to the bottom of the injection assembly 3. At the same time, the lifting motor 65 of the vertical adjustment mechanism 6 drives the lifting belt 64, so that the lifting platform 66 moves up and down along the vertical guide rail 62. The horizontal adjustment mechanism 7's transverse motor 75 drives the moving beam 76 to slide along the transverse guide rail 72 via the transverse belt 74, coordinating to adjust the distribution strip 32 of the injection assembly 3 to the appropriate height and horizontal position aligned with the orifice plate to be injected. The peristaltic pumps in the pump system 4, each corresponding to a nozzle 33, start independently, pumping different liquids through their respective infusion hoses to the nozzles 33 on the distribution strip 32, and the liquid is accurately injected into each hole of that row of the orifice plate. After completing one row, the horizontal moving mechanism 5 steps forward again, sending the next row of holes below the nozzles 33, repeating the above injection action until the entire orifice plate is fully filled.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
