DETAILED DESCRIPTION

[0050] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0051] Example 1

[0052] See also Figure 1 In this embodiment, an intelligent production system and sintering equipment of alumina ceramics are provided, and the process includes the following steps:

[0053] First, the raw materials need to be selected. The raw materials are high-purity alumina powder, which is usually required to have fine and uniform particles to improve the density and performance of the final product.

[0054] Then the material is granulated by the mixing granulating equipment, processed by the molding equipment, and then dried by the drying equipment. The dried material is sintered by the sintering equipment, and finally it is finely processed by the post-processing and quality monitoring equipment, and the quality is monitored in real time.

[0055] In the mixing and granulation, the aluminum oxide powder is mixed with an appropriate amount of additives (such as a binder, a dispersant, etc.), and is uniformly mixed by ball milling, vibration milling, etc. Then, granulation is performed to form particles suitable for molding.

[0056] During molding, commonly used molding methods include compression molding, injection molding and cold isostatic pressing. Through these methods, the particles are pressed into shape to form the desired shape. The molded ceramic body is dried to remove excess moisture and prevent cracking during the subsequent sintering process.

[0057] The dried material body is placed in a sintering device for sintering, usually at a temperature between 1400-1700°C. The sintering process promotes the bonding between particles and improves the density and mechanical properties of the material.

[0058] The sintered material needs to be post-processed. After sintering, it needs to be machined, polished or surface treated to achieve a specific surface finish and dimensional accuracy. In the process, its quality is intelligently monitored;

[0059] Based on this, sensor modules are installed on the entire preparation equipment, and signal transmission is performed through the IoT wireless communication module. The sensor modules include pressure sensors, temperature sensors, humidity sensors, etc. During the entire preparation process, the sensor modules are used to monitor parameters such as temperature and pressure in real time, and transmit their data to the smart terminal. The smart terminal is connected to the sensor module and manufacturing equipment, and signal transmission is also performed through the IoT wireless communication module. The smart terminal receives and analyzes the data from the sensor module, establishes a production model using time series analysis, automatically adjusts equipment parameters and feeds back to the manufacturing equipment, and optimizes the production process through collaborative optimization between multiple manufacturing equipment, thereby achieving the effect of improving production efficiency, reducing energy consumption, and ensuring product consistency and stable performance through intelligent preparation technology.

[0060] Time series analysis algorithms are statistical methods that analyze time series data to identify and predict future trends. Time series data are observations collected in chronological order, usually collected at the same time interval (such as hourly, daily, or monthly). The core goal of time series analysis is to extract patterns from these historical data and make future predictions or anomaly detection based on these patterns.

[0061] In this alumina ceramic intelligent production system, the implementation of the time series analysis algorithm usually involves the following steps:

[0062] 1. Data collection and preprocessing; 2. Selection of appropriate time series analysis algorithms; 3. Model training and evaluation; 4. Model prediction and equipment adjustment; 5. Model training and updating; 6. Feedback and optimization.

[0063] In the intelligent production system of alumina ceramics, the temperature control of the sintering furnace is crucial because the stability of the temperature directly affects the quality of ceramic sintering. The temperature will fluctuate when operating at high temperatures, and sometimes even have a clustering effect (volatility is more concentrated in certain periods). In order to cope with these temperature fluctuations, the GARCH (generalized autoregressive conditional heteroscedasticity) model can be used to model and predict the temperature fluctuations of the sintering furnace.

[0064] The intelligent terminal receives and analyzes the data of the sensor module, establishes a production model based on time series analysis, automatically adjusts the equipment parameters and feeds back to the manufacturing equipment, including using the GARCH model to control the temperature of the sintering equipment, specifically in the following manner:

[0065] S1. The sensor module is installed in the sintering furnace to monitor the fluctuation of temperature data and transmit the temperature data to the smart terminal through the IoT wireless communication module. The sensor records the temperature changes in the furnace in real time, and these data constitute a time series;

[0066] S2. The smart terminal trains a GARCH model based on temperature data to capture the aggregation effect of temperature fluctuations. The temperature time series is set as Y t =μ+∈ t , where ∈ t =σ t Z t , the conditional variance is Among them, Y t is the temperature value at the current moment, ∈ t is the error term, Z t is white noise, It represents the conditional variance, that is, the size of the temperature fluctuation. α0 is called the constant term (or intercept term), which represents the minimum benchmark value of temperature fluctuation in the absence of any fluctuation or shock. It sets the starting point of the conditional variance, that is, the basic fluctuation level. α1 is called the "ARCH term" coefficient, which represents the square of the previous error. The degree of influence on the current fluctuation. The larger the value, the stronger the influence of past fluctuations (i.e., drastic fluctuations or abnormal changes in temperature) on the current temperature fluctuation. β1 is called the "GARCH term" coefficient, which indicates the previous conditional variance Impact on the continuity of the current fluctuation. The larger the value, the stronger the continuity of the fluctuation, and the temperature fluctuation tends to continue the previous fluctuation state. By estimating parameters such as α0, α1, and β1, the model predicts temperature fluctuations to adjust the control response in a timely manner.

[0067] S3. Based on the GARCH model, the system predicts temperature fluctuations and adjusts the heating power of the sintering furnace in advance to smooth temperature changes. If the predicted fluctuation exceeds the tolerance range, the intelligent terminal dynamically adjusts the heating or cooling rate to keep the temperature stable. At the same time, data is shared among the sintering equipment to collaboratively optimize temperature control.

[0068] S4. With continuous data input, the GARCH model automatically updates parameters to better adapt to actual temperature fluctuations. This adaptive feature can continuously optimize the temperature control strategy as production conditions change.

[0069] In summary, the time series analysis algorithm ensures the efficiency of the production process and the stability of product quality through accurate prediction and automatic adjustment in the intelligent production system of alumina ceramics. This method can respond to changes in the production environment in real time, thereby optimizing the production process and reducing production costs.

[0070] Example 2

[0071] See also Figure 2 to Figure 14 In this embodiment, a sintering device for intelligent production of alumina ceramics is provided, which is a link in realizing the intelligent production in Example 1. The specific structure of the sintering device is as follows, including a base 1, and a plurality of supporting feet are provided at the bottom of the base 1, which play an anti-slip buffering effect, making it more stable to place. At the same time, a furnace body 2 is provided in the middle of the upper end of the base 1. The furnace body 2 is a sintering device, which is used to realize the firing of alumina ceramics, and a furnace cover 3 is installed at the upper end of the furnace body 2. The furnace cover 3 is used to realize the sealing of the furnace body 2 to ensure the sealing effect when the ceramics are fired;

[0072] A lifting mechanism 4 is provided at the upper end of the base 1 and located outside the furnace body 2. The lifting mechanism 4 is connected to the furnace cover 3 and can drive the furnace cover 3 to move up or down, thereby opening the furnace cover 3 or sealing the furnace body 2 during firing.

[0073] In addition, a material rack 5 is provided in the furnace body 2, and the top of the material rack 5 is connected to the furnace cover 3. When the furnace cover 3 rises or falls, the material rack 5 also moves together. After the furnace cover 3 rises, it can drive the material rack 5 to extend out of the furnace body 2, and then place the alumina ceramic raw material or take out the fired ceramic. When the furnace cover 3 falls, the material rack 5 moves down and is placed in the furnace body 2.

[0074] In this embodiment, the improvement is aimed at the material rack 5. In the prior art, the material rack 5 is only a simple support plate structure, which cannot realize multi-layer placement, classification placement, etc., and has limitations in use. Moreover, after placing materials on the support plate for a long time and firing at high temperature, it is easy to be worn and stuck with raw materials, which needs to be cleaned, and it is not easy to disassemble and replace;

[0075] Based on the above problems, the material rack 5 in the present invention has a multi-layer structure, which can be placed according to different material classifications, and has an adjustable height, which can adapt to different materials. At the same time, it is a split structure, which is easy to disassemble, convenient for taking and placing materials, and also conducive to its disassembly and maintenance, etc.;

[0076] Specifically, a sealing groove is provided on the lower side of the furnace cover 3, and the sealing groove is plugged into the upper end wall of the furnace body 2, and the two achieve a good sealing effect. In addition, a threaded seat 32 is provided on the left side of the furnace cover 3, and a limiting plate 31 is provided on the right side thereof. The threaded seat 32 is threadedly connected to the lifting mechanism 4, and the limiting plate 31 is slidably connected to the lifting mechanism 4 to achieve a limiting effect.

[0077] The lifting mechanism 4 includes a side plate 41. Two side plates 41 are provided, which are respectively located on the left and right sides of the furnace body 2. The bottom of the side plates 41 is fixed on the base 1. A slide bar 44 is provided in the right side plate 41. The slide bar 44 passes through the limit plate 31 and is fixed on the base 1. The limit plate 31 can slide on the slide bar 44. The two cooperate to achieve the limit effect. A motor 42 is installed on the top of the left side plate 41. The motor shaft of the motor 42 is connected to a screw rod 43. The bottom of the screw rod 43 rotates on the base 1. A screw rod 43 is sleeved on the screw rod 43. The threaded seat 32 is provided with a screw rod 43, so that when the motor 42 is working, it can drive the screw rod 43 to rotate, and the screw rod 43 can drive the threaded seat 32 to move up or down after rotating, and the end of the threaded seat 32 is also slidably connected with the inner wall of the left side plate 41, which further plays a limiting role to keep the threaded seat 32 stable when moving up and down. After the threaded seat 32 moves, the furnace cover 3 will move together, and the limiting plate 31 will also move up or down on the sliding rod 44, so as to realize the lifting and lowering of the furnace cover 3, so that it can be opened or closed;

[0078] When the furnace cover 3 rises or falls, the material rack 5 fixed at the bottom thereof also moves along with it. The material rack 5 comprises a vertical rod 51, the top of which is fixedly connected to the furnace cover 3, and a plurality of insertion holes 54 are provided on the side wall of the vertical rod 51 from top to bottom at equal intervals. In addition, a plurality of material trays 52 are sleeved on the vertical rod 51, and the material trays 52 are fixedly connected to the vertical rod 51 by latches 53. The latches 53 limit the position of the material trays 52. Similarly, after the latches 53 are removed, the material trays 52 can be moved, thereby The distance between the upper and lower material trays 52 can be adjusted to adapt to the height of different materials. When firing materials, they can be placed on different layers of material trays 52 according to different types of materials. Moreover, each material tray 52 is also provided with partitions, and materials can be placed in categories. If the number of materials is small, only one material tray 52 can be installed. In this case, the material can also be placed in categories. The material tray 52 can be set as needed and fixed by a latch 53, which realizes convenient installation and disassembly, and is conducive to the maintenance of the material tray 52 itself.

[0079] The material tray 52 includes a bottom plate 521, a fixing seat 522 is provided in the middle of the bottom plate 521, the fixing seat 522 is sleeved on the vertical rod 51, and a fixing hole 523 is provided on the side wall of the fixing seat 522, which corresponds to the insertion hole 54, and the latch 53 is inserted into the fixing hole 523 and the insertion hole 54, so that the fixing seat 522 and the vertical rod 51 are connected together to form a whole, so as to realize the installation and fixation of the material tray 52;

[0080] The upper end of the chassis 521 is located on the outer side of the fixed seat 522 and is evenly divided into a plurality of grooves 524. A movable plate 525 is placed in the groove 524. The movable plate 525 is plugged into the groove 524. The plug-in form allows the movable plate 525 to be separated from the chassis 521. The material can be placed on the movable plate 525 and then placed in the groove 524. At the same time, the fired ceramic can also be directly taken away as a whole, which improves convenience.

[0081] Moreover, a protective plate 526 is provided at the upper end of the movable disk 525. The protective plate 526 is in direct contact with the material, and can prevent adhesion to avoid affecting the quality of material sintering. The protective plate 526 is installed on the upper surface of the movable disk 525 to protect the entire material disk 52. A fixing component 527 is provided inside the movable disk 525, and the protective plate 526 is fixed to the movable disk 525 through the fixing component 527. The protective plate 526 and the movable disk 525 are not fixedly connected, but are split structures. Therefore, when the protective plate 526 has problems such as wear, it can be replaced alone without replacing the entire movable disk 525. The protective plate 526 is smaller in size and weight, and its replacement is easier, which can also save resources.

[0082] Both ends of the movable plate 525 are provided with handles 5251, which can be conveniently lifted for carrying. Two slots 5252 are provided on the movable plate 525, and the slots 5252 are used to achieve plugging and fixing with the protective plate 526. A hollow structure is provided in the movable plate 525, and a fixing component 527 is installed in the hollow structure. The hollow structure includes a cavity 5255 located in the middle, and a through hole 5256 is provided on the outer side of the cavity 5255, and through grooves 5254 are provided on the left and right sides of the cavity 5255. A slide groove 5253 is provided at the end of the through groove 5254, and the slide groove 5253 is connected with the slot 5252;

[0083] The fixing assembly 527 includes a rotating shaft 5271, which is installed in the through hole 5256. A rotating hole 5272 is provided at the outer end of the rotating shaft 5271, and its inner end is located in the cavity 5255 and rotatably connected to its side wall. Steel wires 5273 are connected to the left and right sides of the rotating shaft 5271. The steel wires 5273 pass through the through slot 5254 and are connected to the limiting rod 5274 located in the slide slot 5253. One end of the limiting rod 5274 close to the slot 5252 is set to an oblique light surface, and the other end is provided with a spring 5275. The spring 5275 can support the limiting rod 5274 to move to the side away from the rotating shaft 5271, so as to fix the protective plate 526. When in use, the bottom of the protective plate 526 is inserted into the slot 5252.

[0084] The lower end of the protective plate 526 is provided with an inserting plate 5261 corresponding to the two slots 5252, and the side wall of the inserting plate 5261 is provided with a limiting hole 5262, and the bottom of the inserting plate 5261 is provided with an inclined surface 5263. When the protective plate 526 is installed, the inserting plate 5261 is aligned with the slot 5252, and then it is pressed down, and the inserting plate 5261 will move down in the slot 5252. At the same time, its inclined surface 5263 will squeeze the limiting rod 5274, so that it moves into the inside of the slide groove 5253 and squeezes the spring 5275. After it continues to move downward, the limiting rod 5274 will be inserted into the limiting hole 5262 under the action of the spring 5275, thereby realizing the fixed limit of the protective plate 526.

[0085] When removing it, insert an external tool into the rotating hole 5272, and then rotate the rotating shaft 5271. After the rotating shaft 5271 rotates, the steel wire 5273 can be wound. When the steel wire 5273 is wound, it will pull the limiting rod 5274 to move toward each other in the sliding groove 5253, thereby disengaging it from the limiting hole 5262. In this way, the protective plate 526 can be removed, and then the rotating shaft 5271 is loosened. Under the action of the spring 5275, the limiting rod 5274 can return to its original position.

[0086] It should be noted here that a control panel, a display screen and other structures can be installed on the side panel 41 of the lifting mechanism 4 to realize intelligent operation of the entire system. The existing technology can be used, and the specific structure and principle will not be repeated in this application.

[0087] In the present invention, the material rack 5 is composed of a vertical rod 51 and a plurality of detachably installed material trays 52, so that the material trays 52 can be set as needed and according to the volume of the material. At the same time, the material can be placed in layers and classified for easy access and placement. It can adapt to different work scenes and has good practicality. It overcomes the limitation of the prior art that only the support plate is used to place materials. Moreover, the protective plate 526 on the material tray 52 is also easy to disassemble. It can be easily replaced after being damaged after long-term use, which facilitates its disassembly and maintenance.

[0088] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
