[0003] The traditional vacuum stirring and mixing system includes a crucible, a heating body for heating the crucible, a closed chamber for placing the crucible, a vacuum pump for evacuating the closed chamber, and a stirring device for stirring the material in the crucible evenly. In specific operation, a variety of materials with specific mass ratios are loaded into the crucible, and the amount of materials loaded into the crucible does not exceed the chamber volume of the crucible. Then the crucible is placed in the chamber and fixed, a stirring device is placed and the furnace cover is covered, and the chamber is evacuated with a vacuum pump. Then, the crucible is heated so that the material in the crucible is heated to a molten state and is evenly mixed together under the stirring action of the stirring device.

[0042] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0043] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0045] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0046] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0047] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.
[0048] Generally, in the process of heating and mixing various materials in the conventional vacuum stirring and mixing system, due to the different melting points of various materials, the material with a lower melting point will melt and be located at the bottom of the crucible during the heating process, and will also sublimate and adhere to the upper side wall of the crucible, which refers to the side wall portion close to the mouth. The material attached to the upper side wall will not be mixed with other molten materials because it will not contact other materials. After the cooling step, the uniformly mixed materials in the crucible cool and become solid, and the material attached to the upper side wall of the crucible also cools and becomes solid. On the one hand, the uniformly mixed materials in the crucible lack materials attached to the upper side walls, resulting in a large deviation between the mass proportions of each material in the final mixed product and the preset mass proportions. On the other hand, when taking out the materials in the crucible, it is inevitable to take out the materials attached to the upper side walls. Since the mass proportions of the materials attached to the side walls are greatly deviated from the preset mass proportions, the materials of the entire mixed product are uneven. Current products, especially organic electroluminescent devices, have extremely high requirements for mixed materials. The materials attached to the upper side walls of the crucible will result in a low qualified rate of the mixed materials.
[0049] Based on this, see Figure 1 and Figure 2 , Figure 1 FIG. 1 shows a working state diagram of the vacuum stirring and mixing system in the first embodiment of the present invention. Figure 2 Another working state diagram of the vacuum stirring and mixing system in the first embodiment of the present invention is shown. The vacuum stirring and mixing system provided by one embodiment of the present invention comprises: a container 10, a heating element 20, a housing 30, a vacuum pump 40, a stirring device 50 and a driving device 60. The container 10 is used to hold materials. The heating element 20 is used to heat the container 10. The container 10 and the heating element 20 are both installed in the housing 30. The vacuum pump 40 is connected to the chamber 12 of the container 10 through a pipe 41. The stirring device 50 is used to stir the material in the container 10. The driving device 60 is used to drive the housing 30 to move so that the heated and melted material in the container 10 can infiltrate the inner wall of the container 10.
[0050] When the vacuum stirring and mixing system is working, multiple materials of a specific mass ratio are loaded into the container 10, for example, the amount of materials loaded into the container 10 does not exceed three quarters of the volume of the chamber 12 of the container 10, the container 10 is evacuated by the vacuum pump 40 to provide a vacuum environment, and then the container 10 is heated by the heating element 20 to melt the materials in the container 10, and the materials in the container 10 are stirred by the stirring device 50 so that various materials are mixed evenly. The driving device 60 can drive the housing 30 to move, and when the housing 30 moves, the molten material in the container 10 soaks the inner wall of the container 10, and when the molten material soaks the inner wall of the container 10, the material attached to the inner wall of the container 10 is also fully mixed with other materials, so that the mass ratio of each material in the final mixed product has a small deviation from the preset mass ratio, and the qualified rate of the mixed product is high.
[0051] It should be noted that the materials in this embodiment are small organic molecules. For example, the melting point difference between the various materials does not exceed 30° C. Further, the melting point difference between the various materials does not exceed 10° C. A large difference in melting points between the various materials will cause the material with a low melting point to sublime, thereby affecting the mass ratio of the mixed product.
[0052] Please refer to Figure 1 and Figure 2 , further, the driving device 60 includes a rotating mechanism 61 and an inclination adjustment mechanism 62. The inclination adjustment mechanism 62 is mounted on the rotating mechanism 61. The rotating mechanism 61 is used to drive the inclination adjustment mechanism 62 to rotate, and the housing 30 is mounted on the inclination adjustment mechanism 62, and the inclination adjustment mechanism 62 is used to adjust the inclination of the bottom wall surface of the housing 30 relative to the horizontal plane. Specifically, the inclination adjustment mechanism 62 includes a bottom plate 623, an elastic member 624, a support plate 622 and a pressing mechanism 625. The support plate 622 is connected to the bottom plate 623 through the elastic member 624. The pressing mechanism 625 is used to press one side of the support plate 622 to adjust the inclination of the support plate 622 relative to the horizontal plane, and the pressing part of the pressing mechanism 625 and the support plate 622 is in sliding contact with the support plate 622. In this way, the rotating mechanism 61 specifically drives the support plate 622 to rotate, and the support plate 622 drives the bottom plate 623 to rotate. When the bottom plate 623 rotates, the bottom plate 623 and the pressing mechanism 625 slide relative to each other. The pressing mechanism 625 and the pressing part of the support plate 622 are in sliding contact with the support plate 622. The pressing mechanism 625 can be specifically set on the ground, a workbench, etc., and does not rotate with the bottom plate 623 and the housing 30.
[0053] Furthermore, the pressing mechanism 625 includes a pressing rod 6251. The pressing rod 6251 is used to press one side of the support plate 622 to adjust the inclination of the support plate 622 relative to the horizontal plane. The bottom plate 623 is disposed on the rotating mechanism 61, and the housing 30 is disposed on the support plate 622. Specifically, when the pushing rod 6251 contacts the top of the support plate 622, when it is necessary to tilt the support plate 622 relative to the horizontal plane, the pushing rod 6251 is moved downward so that one side of the support plate 622 moves downward, and the pushing rod 6251 moves in the opposite direction to release the support plate 622, so that the support plate 622 can be restored to its original state under the action of the elastic member 624; when the pushing rod 6251 contacts the bottom of the support plate 622, when it is necessary to tilt the support plate 622 relative to the horizontal plane, the pushing rod 6251 is moved upward so that one side of the support plate 622 moves upward, and the pushing rod 6251 moves in the opposite direction to release the support plate 622, so that the support plate 622 can be restored to its original state under the action of the elastic member 624, which is also a feasible solution.
[0054] Furthermore, the contact portion between the pressing rod 6251 and the support plate 622 is a smooth surface or is provided with a rotating ball 6252, so that during the rotation of the rotating mechanism 61 and the inclination adjustment mechanism 62, the relative movement between the pressing rod 6251 and the support plate 622 is smoother.
[0055] See also Figure 3 and Figure 4 , Figure 3 A diagram schematically shows one working state of the vacuum stirring and mixing system according to the second embodiment of the present invention; Figure 4 Another working state diagram of the vacuum stirring and mixing system described in the second embodiment of the present invention is shown. Figure 3 and Figure 4 The schematic diagram of the vacuum mixing system and Figure 1 and Figure 2 Compared with the vacuum stirring and mixing system shown in the figure, the main difference lies in the different settings of the rotating mechanism 61 and the inclination adjustment mechanism 62. Figure 3 and Figure 4 In the schematic diagram of the vacuum stirring and mixing system, the driving device 60 includes a rotating mechanism 61 and an inclination adjustment mechanism 62. The rotating mechanism 61 is mounted on the inclination adjustment mechanism 62. The housing 30 is connected to the rotating mechanism 61, and the rotating mechanism 61 is used to drive the housing 30 to rotate. The inclination adjustment mechanism 62 is used to adjust the inclination of the bottom wall surface of the rotating mechanism 61 and the bottom wall surface of the housing 30 relative to the horizontal plane.
[0056] Thus, when the material attached to the inner wall of the container 10 needs to be wetted, the inclination adjustment mechanism 62 adjusts the bottom wall of the housing 30 from a horizontal state to an inclined state, and the bottom wall of the container 10 installed in the housing 30 is adjusted from a horizontal state to an inclined state synchronously, for example, the bottom wall of the container 10 is deflected by 5° to 15° relative to the horizontal plane. Thus, when the rotating mechanism 61 drives the housing 30 to rotate, the housing 30 synchronously causes the tilted container 10 to rotate accordingly. When the tilted container 10 rotates, the molten material in the container 10 can wet the material on the inner wall of the container 10 and be fully mixed with the material.
[0057] See also Figure 3 and Figure 4 In one embodiment, the rotating mechanism 61 is disposed between the housing 30 and the support plate 622 of the inclination adjustment mechanism 62. The rotating mechanism 61 includes a rotating motor, and the rotating shaft of the rotating motor drives the housing 30 to rotate. Thus, when the rotating motor rotates, the rotating shaft of the rotating motor drives the housing 30 to rotate.
[0058] See also Figure 5 and Figure 6 , Figure 5 A diagram showing one of the working states of the vacuum stirring and mixing system according to the third embodiment of the present invention is shown; Figure 6 Another working state diagram of the vacuum stirring and mixing system described in the third embodiment of the present invention is shown. Figure 5 and Figure 6 The schematic diagram of the vacuum mixing system and Figure 3 and Figure 4 The difference between the vacuum stirring and mixing systems shown in the figure mainly lies in the different locations of the rotating mechanism 61. Figure 3 and Figure 4 The rotating mechanism 61 shown in the figure directly drives the housing 30 to rotate. Figure 5 and Figure 6 The illustrated rotating mechanism 61 drives the housing 30 to rotate by means of gears. In another embodiment, the rotating mechanism 61 and the housing 30 are both rotatably arranged on the support plate 622 of the inclination adjustment mechanism 62. The rotating mechanism 61 includes a rotating motor and a first gear connected to the output shaft of the rotating motor, and the outer wall of the housing 30 is provided with a second gear meshing with the first gear. In this way, when the rotating motor rotates, the rotating motor drives the first gear to rotate, and the first gear correspondingly drives the second gear to rotate, and the housing 30 can also be driven to rotate.
[0059] Please refer to Figure 3 and Figure 4Further, the inclination adjustment mechanism 62 includes a lifting mechanism 621 and a support plate 622. The lifting mechanism 621 is located below the support plate 622, and is used to drive one side of the support plate 622 to rise or fall to adjust the inclination of the support plate 622 relative to the horizontal plane. The rotating mechanism 61 and the housing 30 are both disposed on the support plate 622.
[0060] Specifically, the inclination adjustment mechanism 62 further includes a bottom plate 623 disposed below the lifting mechanism 621. Thus, the bottom plate 623 is placed on a flat ground or a workbench according to actual conditions. Of course, as a feasible solution, the bottom plate 623 and the support plate 622 can be omitted, and the inclination of the housing 30 and the rotating mechanism 61 can be changed directly through the lifting mechanism 621.
[0061] See also Figure 7 and Figure 8 , Figure 7 A diagram showing one of the working states of the vacuum stirring and mixing system according to the fourth embodiment of the present invention is shown; Figure 8 Another working state diagram of the vacuum stirring and mixing system described in the fourth embodiment of the present invention is shown. Figure 7 and Figure 8 The vacuum stirring system shown in the figure is Figure 3 and Figure 4 Compared with the vacuum stirring and mixing system shown in the figure, the main difference lies in the different inclination adjustment mechanism 62. Figure 7 and Figure 8 In the schematic diagram of the vacuum stirring and mixing system, the inclination adjustment mechanism 62 includes a bottom plate 623, an elastic member 624, a support plate 622 and a pressing mechanism 625. The support plate 622 is connected to the bottom plate 623 through the elastic member 624, and the pressing mechanism 625 includes a pressing rod 6251. The pressing rod 6251 is used to press one side of the support plate 622 to adjust the inclination of the support plate 622 relative to the horizontal plane. The rotating mechanism 61 and the housing 30 are both arranged on the support plate 622. Specifically, when the pushing rod 6251 contacts the top of the support plate 622, when it is necessary to tilt the support plate 622 relative to the horizontal plane, the pushing rod 6251 is moved downward so that one side of the support plate 622 moves downward, and the pushing rod 6251 moves in the opposite direction to release the support plate 622, so that the support plate 622 can be restored to its original state under the action of the elastic member 624; when the pushing rod 6251 contacts the bottom of the support plate 622, when it is necessary to tilt the support plate 622 relative to the horizontal plane, the pushing rod 6251 is moved upward so that one side of the support plate 622 moves upward, and the pushing rod 6251 moves in the opposite direction to release the support plate 622, so that the support plate 622 can be restored to its original state under the action of the elastic member 624, which is also a feasible solution.
[0062] Furthermore, the elastic member 624 may be a spring or an elastic block, etc., which is not limited here.
[0063] See also Figures 9 to 11 , Fig. 9 A diagram showing one of the working states of the vacuum stirring and mixing system according to the fifth embodiment of the present invention is shown; Fig.10 Another working state diagram of the vacuum stirring and mixing system according to the fifth embodiment of the present invention is shown; Fig.11 Another working state diagram of the vacuum stirring and mixing system according to the fifth embodiment of the present invention is illustrated. In another embodiment, the driving device 60 includes a plurality of lifting mechanisms 621. The lifting mechanisms 621 are arranged at intervals around the bottom periphery of the housing 30, and the lifting mechanisms 621 are used to drive the bottom of the housing 30 to rise or fall. Specifically, the driving device 60 also includes a support plate 622 and a bottom plate 623, and the plurality of lifting mechanisms 621 are all arranged on the bottom plate 623, and the support plate 622 is arranged between the lifting mechanisms 621 and the housing 30. When the lifting mechanism 621 lifts or lowers one side of the bottom of the housing 30, the bottom wall of the housing 30 is tilted accordingly, so that the molten material in the container 10 wets the inner wall of the container 10, and when the molten material wets the inner wall of the container 10, the material attached to the inner wall of the container 10 is also fully mixed with other materials.
[0064] Furthermore, there are four lifting mechanisms 621, and the four lifting mechanisms 621 are arranged at equal intervals around the bottom circumference of the housing 30. When one of the lifting mechanisms 621 is raised, another lifting mechanism 621 arranged opposite to the lifting mechanism 621 is lowered. Of course, the number of lifting mechanisms 621 can also be other numbers, which is not limited here.

In another embodiment, the driving device 60 includes a bottom plate 623, an elastic member 624, a support plate 622 and a pressing mechanism 625. The support plate 622 is connected to the bottom plate 623 through the elastic member 624. The pressing mechanism 625 includes a moving seat 6253, a lifting member and a pressing rod 6251. The moving seat 6253 moves around the circumference of the housing 30, the lifting member is arranged on the moving seat 6253, the pressing rod 6251 is arranged on the lifting member, and the lifting member is used to drive the pressing rod 6251 to move up and down to press one side of the support plate 622 to adjust the inclination of the support plate 622 relative to the horizontal plane, and the housing 30 is arranged on the support plate 622. Specifically, when the pushing rod 6251 is in contact with the top of the support plate 622, when it is necessary to tilt the support plate 622 relative to the horizontal plane, the pushing rod 6251 is moved downward by the lifting member so that one side of the support plate 622 moves downward, and the lifting member drives the pushing rod 6251 to move in the opposite direction to release the support plate 622, and the support plate 622 returns to its original state under the action of the elastic member 624; when the pushing rod 6251 is in contact with the bottom of the support plate 622, when it is necessary to tilt the support plate 622 relative to the horizontal plane, the pushing rod 6251 is moved upward by the lifting member so that one side of the support plate 622 moves upward, and the pushing rod 6251 moves in the opposite direction to release the support plate 622, and the support plate 622 can be restored to its original state under the action of the elastic member 624, which is also a feasible solution.
[0066] Furthermore, a guide rail 6254 is provided around the outer periphery of the housing 30 , and the movable seat 6253 moves along the guide rail 6254 .
[0067] In one embodiment, the inclination in this example is greater than 0° and less than 90°. Preferably, the inclination is 0° to 60°. Specifically, the inclination in this example is 5° to 50°.
[0068] Please refer to Figure 1 and Figure 2 In one embodiment, the container 10 is a crucible, wherein the upper portion of the crucible is open, so that materials can be easily loaded.
[0069] In one embodiment, the chamber 12 includes a cavity 121 with an opening and a sealing cover 122 openably disposed at the opening. The pipeline 41 and the stirring device 50 are both fixed on the sealing cover 122. The stirring device 50 includes a stirring motor 51 and a stirring paddle 52, wherein the stirring motor 51 drives the stirring paddle 52 to rotate, and the rotating shaft of the stirring motor 51 passes through the sealing cover 122, and the rotating shaft of the stirring motor 51 is connected to the stirring paddle 52, and the stirring paddle 52 extends into the container 10. Specifically, the rotating shaft of the stirring motor 51 is tightly matched with the sealing cover 122, thereby ensuring the sealing performance and providing a good vacuum environment for the vacuum chamber 12.
[0070] Furthermore, the vacuum stirring and mixing system further comprises a cooling element for cooling the container 10. The cooling element is arranged in the housing 30 and is located between the sealing cover 122 and the heating element 20. Thus, when the container 10 needs to be cooled, the cooling element works, thereby realizing rapid reduction of the temperature of the container 10.
[0071] For further information, please refer to Figure 1 and Figure 2 The housing 30 is provided with an observation port. Thus, the observation port is used to observe the state of the material in the crucible and the inclination angle of the crucible to prevent the material from overflowing the crucible. It should be noted that the setting position of the observation port on the housing 30 can be set arbitrarily, for example, it can be the top wall of the housing 30, or it can be the side wall of the housing 30, as long as the state of the material in the crucible and the inclination angle of the crucible can be observed through the observation port.
[0072] Furthermore, a fixing member for fixing the container 10 is provided in the chamber 12. In this way, the fixing member fixes the container 10 in the chamber 12 to prevent the container 10 from shaking when tilted.
[0073] Furthermore, the vacuum stirring and mixing system further includes a heat-insulating layer 70. The heat-insulating layer 70 is wrapped around the outer wall of the chamber 12. The heat-insulating layer 70 has a heat-insulating effect on the chamber 12, thereby preventing energy loss during the heating process of the heating element 20, and facilitating the uniform melting and mixing of the materials in the container 10.
[0074] In one embodiment, please refer to Figure 1 and Figure 2 A material mixing method using the vacuum mixing material mixing system described in any of the above embodiments comprises the following steps:
[0075] Providing materials with a preset mass ratio and loading them into the container 10;
[0076] The amount of material loaded into the container 10 does not exceed three quarters of the volume of the chamber 12 of the container 10 .
[0077] The container 10 is evacuated to provide a vacuum environment, and the container 10 is heated by the heating element 20 so that the material in the container 10 is in a molten state;
[0078] Stirring the materials in the container 10 so that the materials are evenly mixed;
[0079] The housing 30 is driven to move, and when the housing 30 moves, the molten material in the container 10 wets the inner wall of the container 10 .
[0080] When the molten material moistens the inner wall of the container 10, the material attached to the inner wall of the container 10 is also fully mixed with other materials.
[0081] In the above-mentioned mixing method of the vacuum stirring mixing system, the molten material in the container 10 soaks the inner wall of the container 10. When the molten material moistens the inner wall of the container 10, the material attached to the inner wall of the container 10 is also fully mixed with other materials. In this way, the deviation between the mass proportion of each material in the final mixed product and the preset mass proportion is small, and the qualified rate of the mixed product is high.
[0082] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0083] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
