Description

Technical Field

[0001] This invention relates to the field of organic thin film crystal material preparation technology, and in particular to an integrated automated preparation platform for organic thin film crystal materials. Background Technology

[0002] Organic thin-film crystal materials are a type of organic semiconductor material and are crucial for the fabrication of 3D stacked devices. Organic thin-film crystal materials formulated with different raw materials exhibit varying physicochemical properties, including different microstructures, emission wavelengths, and lifespans. To obtain formulations that meet specific needs, researchers typically use a high-temperature confinement method. This involves mixing different types and concentrations of liquid raw materials in varying proportions and then subjecting them to prolonged high-temperature heating in a vacuum environment. This process evaporates the solvent, leaving the target solute, which promotes the formation of organically doped crystals between the raw materials.

[0003] In the materials research and development stage, due to the need for timely testing of the physicochemical properties of trial-mixed materials to improve the formulation, numerous permutation and combination experiments involving the types, concentrations, and proportions of materials are typically required. Currently, the standard operating procedure is as follows: First, different solid raw materials are mixed with water to prepare liquid raw materials of specific concentrations. Then, these liquids are added dropwise onto glass slides according to the specified proportions for mixing. During this process, the glass slides are placed on a heated stage for low-temperature preheating. Next, a coverslip is used to cover the mixed droplets, and the entire slide is transferred to a heated stage within a vacuum chamber. Finally, a vacuum is drawn to a specified negative pressure, and the temperature is raised to a specified level. After sufficient organic chemical reaction time, heating is stopped, the vacuum is released, and the entire slide is removed to a heat sink for cooling, ready for subsequent testing. This operation is highly reproducible, and researchers working for extended periods are prone to distraction and fatigue, which can negatively impact the efficiency of high-throughput screening and the effectiveness of material synthesis.

[0004] It is evident that existing technologies still need improvement and enhancement. Summary of the Invention

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1-9 This invention provides an integrated automated preparation platform for organic thin film crystal materials, comprising a platform 1 and a main controller 7. The platform 1 is equipped with a material preparation module 2, a slide transfer module 3, a raw material dispensing module 4, a vacuum heating module 5, and a camera support 6. The material preparation module 2 is equipped with a slide stage 21 and a raw material stage 22. The slide transfer module 3 includes a desktop robot 31, a suction cup 32 located at the output end of the desktop robot 31, a heat dissipation platform 33 located on the platform 1, and a preheating platform 34 located on the platform 1. The suction cup 32 is used to adsorb cover slips and slides. The raw material dispensing module 4 includes a first mounting plate 41, a YZ-axis transfer mechanism 42 located on the first mounting plate 41, a slide 43 located at the output end of the YZ-axis transfer mechanism 42, and a quick-release mechanism 4 on the slide 43. 4. Several pipette tips 45 mounted on the slide 43 and several liquid dispensers 46 mounted on the first mounting plate 41. Each liquid dispenser 46 is connected to the upper end of a pipette tip 45 via a connecting pipe. The lower end of the pipette tip 45 is used to install a pipette tip. A quick-release mechanism 44 is used to remove the pipette tip from the pipette tip 45. The vacuum heating module 5 includes a first lifting mechanism 51, a cavity cover 52 located at the output end of the first lifting mechanism 51, and a vacuum chamber 53 located below the cavity cover 52. The vacuum chamber 53 is equipped with a vacuum pumping assembly 54 and a pressure relief valve 55. A heating platform 56 is located inside the vacuum chamber 53. An industrial camera 61 is mounted on the camera bracket 6. The main controller 7 is electrically connected to the slide transfer module 3, the raw material dripping module 4, the vacuum heating module 5, and the industrial camera 61.

[0030] It should be understood that the aforementioned main controller 7 can be a microcontroller or PLC, capable of processing input signals according to predefined programs and logic, thereby controlling the glass slide transfer module 3, raw material dispensing module 4, vacuum heating module 5, and industrial camera 61 to achieve automated preparation of organic thin film crystal materials. Its specific structure and working principle will not be elaborated further. The aforementioned industrial camera 61 captures the target through digital image processing, converts it into image signals, and transmits them to a dedicated image processing system. The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment actions based on the judgment results. The camera bracket 6 allows adjustment of the industrial camera 61's installation position to ensure that the industrial camera 61 can capture panoramic views.

[0031] Before operation, place the required concentration of liquid raw material reagent bottle and the corresponding number of pipette tips on the stock solution stage 22, and place clean glass slides and coverslips on the slide stage 21. The YZ axis transfer mechanism 42 drives the pipette tip connector 45 to move above the pipette tip and then drives the pipette tip connector 45 downward to install the pipette tip onto the pipette tip connector 45. Throughout the process, the industrial camera 61 assists in positioning and monitors the material preparation process in real time.

[0032] In the first material preparation, the YZ-axis transfer mechanism 42 drives the pipette tip to move to the liquid raw material reagent bottle, and each liquid dispenser 46 is activated so that the corresponding pipette tip picks up a certain amount of liquid raw material. During this process, the desktop robot 31 picks up a clean glass slide and attaches it to the preheating stage 34 using the suction cup 32. The YZ-axis transfer mechanism 42 then drives each pipette tip to move above the glass slide, and under the action of the corresponding liquid dispenser 46, the liquid raw material picked up by the pipette tip drips onto the glass slide. After all the liquid raw material has been added, the desktop robot 31 covers the mixture on the glass slide with a clean coverslip, and then... The entire slide is transferred to the heating platform 56. The first lifting mechanism 51 drives the cavity cover 52 to descend, closing the cavity cover 52 with the vacuum chamber 53. The vacuum pumping component 54 evacuates the vacuum chamber 53, and the heating platform 56 heats the entire slide. After the organic chemical reaction is complete, the pressure relief valve 55 breaks the vacuum in the vacuum chamber 53, and the first lifting mechanism 51 drives the cavity cover 52 to reset. The desktop robot 31 transfers the entire slide to the heat dissipation platform 33. After the entire slide cools down to a certain temperature, the desktop robot 31 transfers the cooled cover glass and the slide to the slide carrier 21, thus completing one material preparation operation.

[0033] The above steps are repeated sequentially until multiple sets of materials are prepared. Finally, the YZ-axis transfer mechanism 42 drives the pipette tip connector 45 to move to the original liquid stage 22, and the quick-release mechanism 44 removes the pipette tip from the connector 45 so that the pipette tip falls onto the original liquid stage 22. Compared with existing technologies, this method can realize the function of automatic preparation of organic thin film crystal materials, reducing manual operation. On the one hand, it can improve the consistency and efficiency of material preparation, ensure the effect of material synthesis, and better achieve high-throughput screening of materials; on the other hand, it can save researchers the time and effort spent in the material preparation process.

[0034] In a preferred embodiment, to make the arrangement of the components more compact and further improve the material preparation efficiency, see [reference needed]. Figure 2The preheating platform 34 and the heat dissipation platform 33 are arranged side by side, both positioned between the desktop robot 31 and the material preparation module 2; the raw material dispensing module 4 is positioned close to the preheating platform 34; and the vacuum heating module 5 is positioned close to the heat dissipation platform 33. Specifically, the preheating platform 34 and the original liquid carrier 22 are on the same straight line, so that the YZ axis transfer mechanism 42 can drive the pipette head to move back and forth between the original liquid carrier 22 and the preheating platform 34, thereby dispensing the liquid raw material drawn from the liquid raw material reagent bottle onto the glass slide located on the preheating platform 34.

[0035] Optionally, the heat sink 33 is equipped with ceramic heat sinks. Due to the special microporous structure of the ceramic heat sinks, the heat dissipation area in contact with air is greatly increased, thus significantly enhancing the heat dissipation effect.

[0036] It should be noted that the preheating stage 34 is a constant temperature heating stage, which can heat the glass slide at low temperature during the liquid drop process.

[0037] In a preferred embodiment, see [reference] Figure 4 The material preparation module 2 also includes a base 23 and two L-shaped positioning blocks 24 mounted on the platform 1. The two L-shaped positioning blocks 24 are used to define the position of the base 23. This configuration facilitates researchers in quickly replacing the material preparation module 2. In actual operation, an additional material preparation module 2 can be added, allowing researchers to prepare the next batch of materials during the preparation of the previous batch, further improving the efficiency of material preparation.

[0038] Furthermore, the two L-shaped positioning blocks 24 are respectively positioned close to the preheating platform 34 and the heat dissipation platform 33, so that researchers can directly push the material preparation module 2 between the two L-shaped positioning blocks 24.

[0039] In a preferred embodiment, see [reference] Figure 4 The slide stage 21 has a first placement position 211 for placing clean coverslips, a second placement position 212 for placing clean slides, several third placement positions 213 for placing cooled coverslips, and several fourth placement positions 214 for placing cooled slides. The clean coverslips in the first placement position 211 and the clean slides in the second placement position 212 are stacked. Each third placement position 213 holds one coverslip, and each fourth placement position 214 holds one slide, to prevent mixing of different materials. The stock solution stage 22 has several first grooves 221 for placing liquid reagent bottles and several second grooves 222 for placing pipette tips. Each liquid reagent bottle corresponds to one pipette tip to prevent mixing of different liquid reagents.

[0040] Furthermore, in one implementation, see [reference] Figure 8Several first grooves 221 and second grooves 222 are arranged side by side, and the first grooves 221 and second grooves 222 are staggered to ensure that the distance between two adjacent first grooves 221 and the distance between two adjacent second grooves 222 are the same as the distance between two adjacent pipette tips 45. During one lifting and lowering movement of the pipette tips 45 driven by the YZ axis transfer mechanism 42, all pipette tips can be inserted into the pipette tips 45, or the pipette tips can draw liquid raw materials from the corresponding liquid raw material reagent bottles. It should be noted that the above embodiment is applicable to mixing two or three liquid raw materials.

[0041] In another implementation, see Figure 9 A plurality of first grooves 221 and second grooves 222 are arranged in a circumferential array on the original liquid stage 22. Correspondingly, the slide 43 is provided with a rotating mechanism 431 and a rotating plate 432 provided at the output end of the rotating mechanism 431. A plurality of pipette tips 45 are arranged in a circumferential array on the rotating plate 432, and a quick-release mechanism 44 is provided on the rotating plate 432. With the above arrangement, in one lifting and lowering movement of the pipette tips 45 driven by the YZ axis transfer mechanism 42, all pipette tips can be installed on the pipette tips 45, and the pipette tips can draw liquid raw materials from the corresponding liquid raw material reagent bottles. Each time liquid raw materials are added to the glass slide, the rotating mechanism 431 drives the rotating plate 432 to rotate by an angle to ensure that each type of liquid raw material is added to the same position on the glass slide. After all liquid raw materials have been added, the rotating mechanism 431 drives the rotating plate 432 to reset.

[0042] In this embodiment, see Figure 6 The YZ axis transfer mechanism 42 includes a horizontal moving mechanism 421 mounted on a first mounting plate 41, a stand 422 mounted on the output end of the horizontal moving mechanism 421, and a second lifting mechanism 423 mounted on the stand 422. A slide 43 is mounted on the output end of the second lifting mechanism 423. The horizontal moving mechanism 421 and the second lifting mechanism 423 can each be linear modules. The horizontal moving mechanism 421 drives the stand 422 to move horizontally, thereby driving the pipette head to move back and forth between the original liquid stage 22 and the preheating stage 34. The second lifting mechanism 423 drives the pipette head to move up and down, thereby assisting the pipette head in absorbing and discharging liquid.

[0043] In a preferred embodiment, see [reference] Figure 5The liquid extractor 46 includes a mounting bracket 461 on a first mounting plate 41, a first linear motor 462 at one end of the mounting bracket 461, and a sample injector 463 at the other end of the mounting bracket 461. Specifically, the sample injector 463 includes a connecting part 4631 and a suction part 4632. The connecting part 4631 is connected to one end of a connecting tube. A first air passage is opened in the connecting part 4631. A second air passage is opened in the suction part 4632, which is coaxial with the first air passage. A piston 464 is slidably connected in the sample injector 463. The piston 464 is slidably connected to the second air passage. The extension rod of the first linear motor 462 is connected to a push rod 465, which is connected to the piston 464. When the extension rod of the first linear motor 462 extends, it drives the push rod 465 to move toward the inside of the injector 463, that is, the piston 464 slides into the second air passage a certain distance, and the liquid in the pipette head is discharged; conversely, when the extension rod of the first linear motor 462 retracts, it drives the push rod 465 to move away from the injector 463, that is, the piston 464 slides out of the second air passage a certain distance, and the pipette head draws up part of the liquid raw material.

[0044] Furthermore, a sensing block 466 is provided at the connection position between the first linear motor 462 and the push rod 465, and a sensor 467 for detecting the sensing block 466 is provided on the mounting bracket 461. Preferably, the sensor 467 is a photoelectric switch. When the extension rod of the first linear motor 462 is in the retracted state, the push rod 465 is in the zero position. At this time, the sensing block 466 is within the detection range of the photoelectric switch. When a certain amount of liquid raw material needs to be drawn, the first linear motor 462 first drives the push rod 465 to move towards the injector 463, so that the piston 464 moves a certain distance into the second air channel to expel most of the air. The pipette tip is immersed in the liquid raw material reagent bottle. The first linear motor 462 drives the push rod 465 to move away from the injector 463, so that the piston 464 exits a small distance into the second air channel to ensure that the pipette tip draws the corresponding amount of liquid raw material and improves the accuracy of the liquid ratio of each raw material.

[0045] To achieve automatic pipette tip removal, please refer to... Figure 6 , 7 The quick-release mechanism 44 includes a second linear motor 441 mounted on a slide 43 and a push plate 442 mounted on the output end of the second linear motor 441. The push plate 442 has several through holes 4421 corresponding one-to-one with the pipette tip connector 45. The through holes 4421 are coaxial with the pipette tip connector 45, and the inner diameter of the through holes 4421 is larger than the outer diameter of the pipette tip connector 45. With the above configuration, the second linear motor 441 drives the push plate 442 to move downward, and the through holes 4421 push out the pipette tip stuck in the pipette tip connector 45, and the pipette tip falls onto the stock solution stage 22; then the second linear motor 441 drives the push plate 442 to reset, so that the next batch of pipette tips can be inserted into the pipette tip connector 45.

[0046] Furthermore, the stock solution stage 22 is also provided with a third groove 223 for placing used pipette tips. Specifically, the inner diameter of the second groove 222 matches the pipette tip, and the second groove 222 is used to place unused pipette tips. The second groove 222 has high positioning accuracy for unused pipette tips, which is beneficial for the pipette tips to be installed on the pipette tip connector 45. The inner diameter of the third groove 223 is larger than that of the pipette tip, which is beneficial for the quick-release mechanism 44 to remove the used pipette tip, so that the pipette tip can fall accurately into the third groove 223.

[0047] In a preferred embodiment, see [reference] Figure 2 The vacuum heating module 5 further includes two parallel mounting rods 57 and a second mounting plate 58 slidably mounted on the mounting rods 57. The first lifting mechanism 51 and the vacuum chamber 53 are both mounted on the second mounting plate 58. Specifically, the mounting rods 57 can be made of aluminum profiles to facilitate adjustment of the position of the second mounting plate 58 on the two mounting rods 57, that is, to adjust the distance between the vacuum chamber 53 and the heat dissipation platform 33, ensuring that the desktop robot 31 can move the glass slide entirely into or out of the vacuum chamber 53.

[0048] In this embodiment, the first lifting mechanism 51 can be a linear module that can drive the cavity cover 52 to move up and down.

[0049] Further, see Figure 4 The vacuum chamber 53 has four mounting channels 531 on its peripheral wall, each with a clamp connector. Specifically, the vacuum assembly 54 includes a vacuum pump 541 and a negative pressure controller 542. A bellows 543 connects the vacuum pump 541 to the vacuum chamber 53, and the negative pressure controller 542 is located on the vacuum chamber 53. A heating stage controller 561 is externally connected to the heating stage 56 to control its heating temperature. One mounting channel 531 is connected to the bellows 543 via a clamp connector; a second mounting channel 531 is connected to the negative pressure controller 542 via a clamp connector; a third mounting channel 531 is connected to an aviation connector 562 via a clamp connector to achieve electrical connection between the heating stage 56 and the heating stage controller 561; and a fourth mounting channel 531 is connected to a pressure relief valve 55 via a clamp connector. Through the above configuration, the sealing between the vacuum chamber 53 and the chamber cover 52 can be guaranteed.

[0050] In a preferred embodiment, see [reference] Figure 3The platform 1 includes a cabinet 11, a tabletop 12 on top of the cabinet 11, and a cabinet door 13 hinged to the cabinet 11. The tabletop 12 has several wire holes 121, and the bottom of the cabinet 11 is equipped with several casters 14. The cabinet 11 is used to house equipment such as a vacuum pump 541, a hot plate controller 561, a main controller 7, and a low-voltage distribution box. The cabinet 11 is also equipped with a cooling fan 15 to facilitate ventilation and heat dissipation of the equipment inside. The tabletop 12 has multiple wire holes 121 to facilitate wire threading and allow for neat storage of all wires.

[0051] In this embodiment, see Figure 1 The cabinet 11 is equipped with four casters 14 at the bottom. Preferably, the casters 14 are fusible wheels. Fusible wheels can adjust the height and roll, making it easy to adjust the tabletop 12 to a horizontal state and to move the platform 1 to various positions.

[0052] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
