Technical Field
[0001] This invention relates to the field of solution preparation technology, and in particular to a solution homogenization device and method for quantum dot film preparation. Background Technology
[0002] Quantum dot films are thin film structures prepared using quantum dot materials, possessing beneficial optoelectronic properties. Due to their advantages such as high color saturation, low energy consumption, and low manufacturing cost, quantum dot films are widely used in LEDs, solar cells, and displays. As a light-emitting or absorber layer, the structure of quantum dot films is usually "sandwich-like," namely, thin film-quantum dot adhesive-thin film. The quantum dot adhesive is composed of a quantum dot dispersion system and a resin adhesive. In the production process of quantum dot adhesive, the quantum dot dispersion and the resin adhesive need to be formulated to make the resulting quantum dot film suitable for different applications.
[0003] Existing quantum dot dispensing equipment mostly involves simply stirring the quantum dot dispersion system and the resin adhesive. However, due to the viscosity of the resin adhesive, it is not easy to disperse, resulting in uneven dispensing of the quantum dot adhesive. Furthermore, the dispensing process requires a significant amount of time, leading to low dispensing efficiency. Therefore, there is an urgent need for a solution homogenization dispensing device and method for quantum dot film preparation to solve the above problems. Summary of the Invention
[0004] In order to overcome the shortcomings of existing mixing devices where materials are only stirred by a stirring rod, resulting in material stratification and local aggregation, and thus uneven mixing of materials, this invention provides a solution homogenization mixing device and method for quantum dot film preparation.
[0005] The technical solution of the present invention is as follows: a solution homogenization device for quantum dot film preparation, comprising: a frame; a mixing tank fixedly connected to the frame, wherein a motor is installed in the mixing tank, and the mixing tank is provided with a feed connection flange, a feed pipe and a discharge connection flange; a rotating main shaft rotatably connected to the mixing tank, the rotating main shaft being fixedly connected to the output shaft of the motor on the mixing tank; multiple stirring rods arranged at intervals, all fixedly connected to the rotating main shaft, each stirring rod being fixedly connected to a stirring blade, the stirring blade being placed at an angle to circulate the material within the mixing tank; and a premixing mechanism disposed within the mixing tank for premixing different materials.
[0006] Furthermore, the stirring blades are twisted to circulate the material within the mixing tank.
[0007] Further, the premixing mechanism includes: a first disc and a second disc, both rotatably connected inside the mixing tank, both the first disc and the second disc being fixedly connected to the rotating main shaft, and a first cavity being provided between the second disc and the mixing tank; multiple feeders arranged at intervals, all disposed between the first disc and the second disc, each feeder having a second cavity, multiple through holes and multiple feed channels, the through holes communicating with adjacent feed channels and communicating with the second cavity; multiple feed pipes arranged at intervals, fixedly connected between the rotating main shaft and the feeders, the feed pipes communicating with the second cavity; the feeder having a third cavity, the third cavity communicating with the first cavity through an intermediate pipe; and multiple atomizing nozzles installed on the feeder, the atomizing nozzles communicating with adjacent third cavities and adjacent feed channels.
[0008] Furthermore, the atomizing nozzles are placed at an angle to blow material in adjacent areas.
[0009] Furthermore, it also includes: a plurality of limiting rods arranged at intervals, which are respectively fixedly connected to adjacent material feeding components; the first disc and the second disc are both slidably connected to the material feeding components; the material feeding pipe and the intermediate pipe between the material feeding components and the first disc are all made of soft material; the mixing tank is provided with a first limiting groove, which is used to limit the limiting rods.
[0010] Furthermore, the first limiting groove is a wavy closed groove, which is used to allow the material feeder to slide relative to the second disc.
[0011] Furthermore, it also includes: a piston component slidably connected to the rotating main shaft, the piston component being equipped with a one-way valve, a fourth cavity being provided inside the rotating main shaft, the piston component being located inside the fourth cavity, a discharge hole being provided inside the rotating main shaft, an intermediate channel being provided inside the stirring rod, the intermediate channel being connected to the fourth cavity, a one-way valve being installed inside the intermediate channel, a fifth cavity being provided inside the stirring blade, the fifth cavity being connected to the adjacent intermediate channel, and the stirring blade being provided with spaced-apart feed holes; and a transmission assembly being provided inside the mixing tank for causing the piston component to slide relative to the rotating main shaft.
[0012] Furthermore, the transmission assembly includes: a limiting member fixedly connected to the mixing tank, the limiting member being provided with a second limiting groove; a sliding shell splinedly connected to the rotating main shaft, the sliding shell being slidably connected to the limiting member, an elastic element being provided between the limiting member and the sliding shell, a limiting block being installed on the sliding shell, and the second limiting groove being used to limit the limiting block.
[0013] Furthermore, the second limiting groove is composed of a spiral groove and a vertical groove connected end to end, and the projection of the spiral groove on the horizontal plane is 360°, which is used to guide the limiting block.
[0014] A method for uniformly preparing a solution for quantum dot film preparation, based on the aforementioned apparatus for uniformly preparing a solution for quantum dot film preparation, includes the following steps:
[0015] Step 1: The resin is transferred into the feed flange using the pump. The resin enters the second chamber through the feed pipe, and then enters the feed channel through the adjacent through hole. At the same time, the quantum dot dispersion system enters the first chamber through the feed pipe, and then enters the third chamber through the intermediate pipe. After being atomized by the atomizing nozzle, the quantum dot dispersion system enters the feed channel and comes into contact with the thin strips of resin, so that the two are premixed during the feeding process.
[0016] Step 2: Use the output shaft of the motor to drive the rotating main shaft to rotate counterclockwise. The stirring blades begin to compress the mixture in adjacent areas, thereby causing the mixture to move. This allows the mixture to circulate between the inner and outer layers in the mixing tank. At the same time, the mixture is also affected by the tortuous area on the stirring blades, causing it to circulate up and down in the mixing tank.
[0017] Step 3: The limiting rod, under the action of the first limiting groove, begins to move repeatedly towards and away from the rotating main shaft. The limiting rod drives the material passing component to move together, so that the mixture coming out of the material passing channel on the material passing component is distributed in a ring shape and also locally in a wave shape, so that the mixtures of the same layer height gathered in the mixing tank are intertwined.
[0018] Step 4: The limiting block begins to move under the limiting action of the spiral groove on the second limiting groove. The sliding shell slides relative to the limiting part, and a pressure change occurs in the fourth cavity. This causes the mixture in the mixing tank to enter the fourth cavity through the feed hole and the intermediate channel, and finally to be discharged through the discharge hole and re-enter the mixing tank, thus completing the circulation of the mixture in the mixing tank.
[0019] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention uses stirring blades to squeeze the mixture from adjacent areas outwards, thereby causing the mixture to circulate between the inner and outer layers within the mixing tank, increasing the degree of movement of the mixture and thus preventing stratification and local aggregation within the mixing tank, which would reduce mixing efficiency and effect. The mixture is also affected by the torsional area on the stirring blades, circulating up and down within the mixing tank, further increasing the degree of movement and improving mixing efficiency and effect. The quantum dot dispersion system, atomized by the atomizing nozzle, enters the material passage and contacts the thin strips of resin adhesive, thereby allowing both to move together during the feeding process. Premixing reduces the difficulty of subsequent blending and improves blending efficiency. By limiting the limiting rod through the first limiting groove, the mixture coming out of the material channel on the material feeder is distributed in a ring shape and also locally in a wave shape. This allows the mixtures of the same height gathered in the blending tank to interweave, thereby improving the blending efficiency and quality. The relative sliding between the piston and the rotating main shaft allows the mixture in the blending tank to circulate further (from top to top and from outside to inside), thereby increasing the degree of movement of the resin glue and quantum dot dispersion system, increasing the probability of contact between the two, and thus improving the blending efficiency.

Detailed Implementation
[0031] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.
[0032] like Figures 1-4 As shown in the figure, an embodiment of the present invention is proposed, which provides a solution homogenization mixing device for quantum dot film preparation. This device solves the problem in existing mixing devices where materials are only stirred by a stirring rod, resulting in material stratification and local aggregation, leading to uneven mixing. The device includes: a frame 1; a mixing tank 2, fixedly connected to the frame 1, with a motor installed in the mixing tank 2, and equipped with a feed flange, a feed pipe, and a discharge flange; a rotating main shaft 3, rotatably connected to the mixing tank 2, and fixedly connected to the output shaft of the motor on the mixing tank 2; multiple stirring rods 4 arranged at intervals, all fixedly connected to the rotating main shaft 3, with stirring blades 5 fixedly connected to the stirring rods 4. The stirring blades 5 are inclined and used to transfer materials in the mixing tank 2. The stirring blades 5 are twisted to circulate materials within the mixing tank 2; and a premixing mechanism, disposed in the mixing tank 2, for premixing different materials.
[0033] In the above scheme, the feed connection flange and feed pipe are both located at the upper part of the mixing tank 2, and the discharge connection flange is located at the lower part of the mixing tank 2. The feed connection flange on the mixing tank 2 is connected to the external resin storage tank, and the resin is transferred into the feed connection flange by a pump. The feed pipe on the mixing tank 2 is connected to the external quantum dot dispersion system storage tank, and the quantum dot dispersion system is transferred into the feed pipe by a pump. The discharge connection flange on the mixing tank 2 is connected to the external collection device for collecting the mixed quantum dot colloid. Multiple inclined stirring blades 5 at different heights are staggered in the horizontal direction to make the material in the mixing tank 2 circulate internally and externally (in layers). The twisted area on the stirring blades 5 is used to make the material in the mixing tank 2 circulate vertically (in layers), thereby improving the uniformity of the stirred material.
[0034] When it is necessary to prepare quantum dot colloids, the resin is introduced into the feed flange, and the quantum dot dispersion system is introduced into the feed pipe. After being processed by the premixing mechanism, it enters the mixing tank 2. As the feeding time increases, the resin and quantum dot dispersion system (hereinafter referred to as a mixture for ease of description) gradually accumulate in the mixing tank 2. Feeding is stopped once the mixture has accumulated to a certain amount. Subsequently, the output shaft of the motor drives the main shaft 3 to rotate counterclockwise (e.g., ...). Figure 3 (Taking a top view as an example), the rotating main shaft 3 drives the adjacent stirring blades 5 to rotate counterclockwise through the stirring rod 4. The upper and lower stirring blades 5 begin to gather the mixture in the adjacent areas towards the center, while the middle stirring blade 5 squeezes the mixture in the adjacent areas outwards. This causes the mixture to circulate between the inner and outer layers within the mixing tank 2, increasing the degree of movement of the mixture and thus preventing the mixture from stratifying and locally agglomerating within the mixing tank 2, which would reduce mixing efficiency and effect. During the process, the mixture is also affected by the tortuous area on the stirring blades 5, circulating up and down within the mixing tank 2, further increasing the degree of movement of the mixture and further improving mixing efficiency and effect.
[0035] like Figure 2 , Figures 4-6As shown, the premixing mechanism includes: a first disc 601 and a second disc 602, both rotatably connected to the mixing tank 2. Both the first disc 601 and the second disc 602 are fixedly connected to the rotating main shaft 3. A first cavity 603 is provided between the second disc 602 and the mixing tank 2. Multiple feeders 604 are spaced apart and positioned between the first disc 601 and the second disc 602. Each feeder 604 has a second cavity 605, multiple through holes, and multiple feed channels. The through holes communicate with adjacent feed channels, and the through holes communicate with the second... The cavity 605 is connected; multiple feed pipes 606 are arranged at intervals and are fixedly connected between the rotating main shaft 3 and the feed component 604. The feed pipes 606 are connected to the second cavity 605. The feed component 604 is provided with a third cavity 607. The third cavity 607 is connected to the first cavity 603 through an intermediate pipe. The feed component 604 is equipped with multiple atomizing nozzles. The atomizing nozzles are connected to the adjacent third cavity 607 and the adjacent feed channel. The atomizing nozzles are placed at an angle and are used to blow the material in the adjacent area.
[0036] In the above scheme, the distance between two adjacent material channels on the material conveyor 604 gradually decreases from the side closest to the rotating main shaft 3 to the other side. Based on the area variation at different inner diameters within the mixing tank 2, the arrangement of the material channels on the material conveyor 604 is adjusted to ensure that the upper surface of the mixture accumulated in the mixing tank 2 rises horizontally. This prevents uneven horizontal distribution of the mixture in the mixing tank 2, which would lead to uneven mixing after preparation and thus affect the preparation of the quantum dot film. The multiple through-holes on the material conveyor 604 are divided into several groups, each group consisting of six circumferentially distributed through-holes. Each group of through-holes is connected to an adjacent material channel. The edge region of the through-hole is "higher" than the adjacent region on the material conveyor 604, allowing the material to flow from the through-hole... The resin adhesive moves downwards in thin strips. The distribution of multiple atomizing nozzles is the same as that of multiple through holes. After the resin adhesive enters the feed connection flange, it enters the second chamber 605 through the feed pipe 606. Then, the resin adhesive enters the feed channel through the adjacent through holes on the feed component 604. At the same time, the quantum dot dispersion system enters the first chamber 603 through the feed pipe. Subsequently, the quantum dot dispersion system enters the third chamber 607 through the intermediate pipe between the feed component 604 and the first disc 601. After being atomized by the atomizing nozzles, it enters the feed channel and comes into contact with the thin strips of resin adhesive. This allows the two to be premixed during the feeding process, thereby reducing the difficulty of subsequent mixing work and improving mixing efficiency.
[0037] During the counterclockwise rotation of the main shaft 3, the main shaft 3 drives the first disc 601 and the second disc 602 to rotate counterclockwise together. The first disc 601 and the second disc 602 together drive the feeder 604 to rotate counterclockwise together, so that the resin glue and quantum dot dispersion system are evenly accumulated in the mixing tank 2.
[0038] like Figures 5-7As shown, it also includes: multiple limiting rods 701 arranged at intervals, which are fixedly connected to adjacent feeders 604 respectively; the first tray 601 and the second tray 602 are both slidably connected to the feeders 604; the feed pipe 606 and the intermediate pipe between the feeders 604 and the first tray 601 are all made of soft material; the mixing tank 2 is provided with a first limiting groove 702, which is used to limit the limiting rods 701; the first limiting groove 702 is a wavy closed groove, which is used to allow the feeders 604 and the second tray 602 to slide relative to each other.
[0039] In the above scheme, there are arc-shaped areas with different diameters on the first limiting groove 702, which are used to change the position of the feeder 604 on the second plate 602. During the counterclockwise rotation of the feeder 604, the feeder 604 drives the adjacent limiting rod 701 to rotate counterclockwise together. The limiting rod 701 begins to slide in the first limiting groove 702. During the process, the limiting rod 701 is limited by the first limiting groove 702 and begins to move repeatedly towards and away from the rotating main shaft 3. The limiting rod 701 drives the feeder 604 to move together, so that the mixture coming out of the feeder channel on the feeder 604 is distributed in a ring shape and also locally in a wave shape. This makes the mixtures of the same layer height gathered in the mixing tank 2 intersect each other, thereby improving the mixing efficiency and mixing quality of the mixture.
[0040] like Figures 8-10 As shown, it also includes: a piston 801, slidably connected to the rotating main shaft 3, the piston 801 is equipped with a one-way valve, a fourth cavity 802 is provided inside the rotating main shaft 3, the piston 801 is located in the fourth cavity 802, the rotating main shaft 3 is provided with a discharge hole 803, an intermediate channel 804 is provided inside the stirring rod 4, the intermediate channel 804 is connected to the fourth cavity 802, a one-way valve is installed inside the intermediate channel 804, a fifth cavity 805 is provided inside the stirring blade 5, the fifth cavity 805 is connected to the adjacent intermediate channel 804, and the stirring blade 5 is provided with spaced feed holes 806; and a transmission assembly, provided inside the mixing tank 2, for causing the piston 801 to slide relative to the rotating main shaft 3.
[0041] In the above scheme, the flow direction of the one-way valve on the piston 801 is from bottom to top, and there are multiple circumferentially distributed discharge holes 803 to ensure uniform distribution of the mixture. The flow direction of the one-way valve in the middle channel 804 is from one side away from the rotating main shaft 3 to the other side. The feed holes 806 are vertically distributed on the stirring blades 5, and multiple vertical stirring blades 5 completely cover the mixing area in the mixing tank 2. During the mixing process, due to the action of the transmission assembly, a negative pressure appears in the lower part of the fourth cavity 802, and this pressure is released through the feed holes 806. 06. The mixture in the adjacent area is drawn in. After passing through the fifth chamber 805, the intermediate channel 804 and the adjacent one-way valve, the mixture enters the fourth chamber 802. Then, the mixture passes through the one-way valve on the piston 801 and finally passes through the discharge hole 803 and is discharged into the mixing tank 2. This allows the mixture to circulate further in the mixing tank 2 (circulating from top to top and from outside to inside), thereby increasing the degree of movement of the resin glue and quantum dot dispersion system, increasing the probability of contact between the two, and thus improving the mixing efficiency of the two.
[0042] like Figures 8-10 As shown, the transmission assembly includes: a limiting member 901, fixedly connected to the mixing tank 2, the limiting member 901 being provided with a second limiting groove 902; a sliding shell 903, splinedly connected to the rotating main shaft 3, the sliding shell 903 being slidably connected to the limiting member 901, an elastic element being provided between the limiting member 901 and the sliding shell 903, a limiting block 904 being installed on the sliding shell 903, the second limiting groove 902 being used to limit the limiting block 904, the second limiting groove 902 being composed of a spiral groove and a vertical groove connected end to end, and the projection of the spiral groove on the horizontal plane being 360°, used to guide the limiting block 904.
[0043] In the above scheme, the elastic element between the limiting member 901 and the sliding shell 903 is a spring, which is used to apply pressure to the sliding shell 903. During the counterclockwise rotation of the rotating main shaft 3, the rotating main shaft 3 drives the sliding shell 903 to rotate counterclockwise together, and the sliding shell 903 drives the limiting block 904 to rotate counterclockwise together (taking the limiting block 904 located at the lower end of the spiral groove on the second limiting groove 902 as an example). Under the limiting action of the spiral groove on the second limiting groove 902, the limiting block 904 begins to move upward, and the limiting block 904 drives the sliding shell 903 to move upward together. The sliding shell 903 and the limiting member 901 slide relative to each other, and the elastic element is compressed. The sliding shell 903 drives the piston member 801 to move upward together. At this time, no material passes through the piston member 801 (that is, the one-way valve on it is not open), and a negative pressure appears in the lower part of the fourth cavity 802, thereby starting to draw the mixture in the mixing tank 2, thus completing the subsequent cycle work.
[0044] like Figures 1-10As shown in the figure, an embodiment of the present invention is proposed, which provides a method for uniformly preparing a solution for quantum dot film preparation. Based on the above-mentioned apparatus for uniformly preparing a solution for quantum dot film preparation, the method includes the following steps:
[0045] Step 1: The resin is transferred into the feed flange using the pump. The resin enters the second chamber 605 through the feed pipe 606, and then enters the feed channel through the adjacent through hole. At the same time, the quantum dot dispersion system enters the first chamber 603 through the feed pipe, and then enters the third chamber 607 through the intermediate pipe. After being atomized by the atomizing nozzle, the quantum dot dispersion system enters the feed channel and comes into contact with the thin strips of resin, so that the two are premixed during the feeding process.
[0046] Step 2: Use the output shaft of the motor to drive the rotating main shaft 3 to rotate counterclockwise. The stirring blade 5 begins to squeeze the mixture in the adjacent area, thereby causing the mixture to move. This allows the mixture to circulate between the inner and outer layers in the mixing tank 2. At the same time, the mixture is also affected by the tortuous area on the stirring blade 5, causing it to circulate up and down in the mixing tank 2.
[0047] Step 3: The limiting rod 701, under the limiting action of the first limiting groove 702, begins to move repeatedly towards and away from the rotating main shaft 3. The limiting rod 701 drives the material passing component 604 to move together, so that the mixture coming out of the material passing channel on the material passing component 604 is distributed in a ring shape and also locally in a wave shape, so that the mixtures of the same layer height gathered in the mixing tank 2 are intertwined.
[0048] Step 4: The limiting block 904 begins to move under the limiting action of the spiral groove on the second limiting groove 902. The sliding shell 903 slides relative to the limiting member 901, and a pressure change occurs in the fourth cavity 802. This causes the mixture in the mixing tank 2 to enter the fourth cavity 802 through the feed hole 806 and the intermediate channel 804, and finally to be discharged through the discharge hole 803 and re-enter the mixing tank 2, thus completing the circulation of the mixture in the mixing tank 2.
[0049] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.

A method for uniformly preparing a solution for quantum dot film preparation, characterized in that, The specific method of using the solution homogenization device for quantum dot film preparation according to claim 5 is as follows: Step 1: The resin is transferred into the feed flange using the pump body. The resin enters the second chamber (605) through the feed pipe (606), and then enters the feed channel through the adjacent through hole. At the same time, the quantum dot dispersion system enters the first chamber (603) through the feed pipe. Subsequently, the quantum dot dispersion system enters the third chamber (607) through the intermediate pipe, and then enters the feed channel after being atomized by the atomizing nozzle, and comes into contact with the thin strip of resin, so that the two are premixed during the feeding process. Step 2: Use the output shaft of the motor to drive the rotating main shaft (3) to rotate counterclockwise. The stirring blade (5) begins to squeeze the mixture in the adjacent area, thereby causing the mixture to move. This allows the mixture to circulate between the inner and outer layers in the mixing tank (2). At the same time, the mixture is also affected by the tortuous area on the stirring blade (5), and circulates up and down in the mixing tank (2). Step 3: The limiting rod (701) is limited by the first limiting groove (702) and begins to move repeatedly towards and away from the rotating main shaft (3). The limiting rod (701) drives the material passing part (604) to move together, so that the mixture coming out of the material passing channel on the material passing part (604) is distributed in a ring shape and also locally in a wave shape, so that the mixtures of the same layer height gathered in the mixing tank (2) are intertwined. Step 4: The limiting block (904) begins to move under the limiting action of the spiral groove on the second limiting groove (902). The sliding shell (903) slides relative to the limiting part (901), and a pressure change occurs in the fourth cavity (802). This causes the mixture in the mixing tank (2) to enter the fourth cavity (802) through the feed hole (806) and the intermediate channel (804), and finally to be discharged through the discharge hole (803) and re-enter the mixing tank (2), thus completing the circulation of the mixture in the mixing tank (2).
