Description

Technical Field

[0001] The invention belongs to the technical field of ceramic plate suction and transportation, and in particular relates to a method for adsorbing ceramic thin plates. Background Art

[0002] Ceramic sheets are widely used in architectural decoration and home renovation due to their high strength, excellent flatness, and decorative properties. However, due to their thinness (typically 2.5-5.5mm) and brittleness, they are prone to cracking and breakage during adsorption operations during production, transportation, and installation due to uneven adsorption force distribution and insufficient pressure control precision, resulting in economic losses. Existing adsorption technologies mostly use a uniform negative pressure field or a fixed array adsorption mode, which has the following defects: First, it is impossible to accurately identify the micro-texture, pores and defect distribution on the surface of the ceramic thin plate, resulting in poor adaptability between the adsorption unit and the plate surface and frequent local pressure concentration; second, there is a lack of effective control of the edge effect during the adsorption process, and the edge area of ​​the plate is prone to micro-deformation due to pressure fluctuations, which can cause fracture after long-term accumulation; third, the traditional adsorption method has not established a complete closed-loop feedback mechanism, and it is difficult to dynamically adjust the adsorption parameters according to changes in the plate material, thickness and environmental conditions, and the adaptability is obviously limited; fourth, the impact force at the moment of contact lacks a buffer design, and rigid contact can easily cause hidden damage to the plate surface, affecting product quality. Furthermore, existing technologies for controlling adsorption systems often employ a single hierarchical architecture, resulting in poor module coordination and high response latency, making them unable to meet the demands of high-precision and high-efficiency adsorption operations. Therefore, developing a ceramic plate adsorption method that can achieve precise identification, dynamic control, safe buffering, and coordinated efficiency has become a pressing technical challenge in this field. Summary of the Invention

[0003] The object of the present invention is to provide a method for adsorbing ceramic thin plates to solve the problems raised in the above background technology.

[0004] In view of this, the present invention provides a method for adsorbing a ceramic thin plate, comprising the following steps: S1. Surface Feature Map Construction: A multispectral sensing unit scans the entire surface of the ceramic plate to be adsorbed. This unit integrates visible light imaging, infrared thermal imaging, and laser imaging to capture full-scale features, from nanoscale microtextures to millimeter-scale macrodefects. This generates a 3D feature map that includes the orientation and density distribution of microtextures, pore size and depth parameters, and the 3D coordinates and geometric morphology of multiple defect types. The map data is stored and transmitted using encrypted encryption to ensure information integrity. S2. Adsorption Array Topology Planning: Based on the characteristic map, a distributed computing unit dynamically allocates the spatial arrangement of flexible adsorption units, creating a biomimetic force flow path between the rigid support frame and the panel surface. This path evenly transmits the adsorption force from each adsorption unit to the entire support frame. During the planning process, the stress and strain distribution under different arrangement schemes is simulated in real time to select the optimal solution. S3. Establishing a gradient negative pressure field: A non-uniform pressure field is created in the adsorption area using a multi-chamber vacuum generation system. This system consists of several independently controlled vacuum chambers, each connected to a corresponding adsorption unit group via precision piping. The pressure gradient is negatively correlated with the defect distribution in the characteristic map, with lower negative pressure values ​​corresponding to areas with dense defects, and higher negative pressure values ​​corresponding to areas without defects or with sparse defects. During the pressure field establishment process, the pressure change curve of each area is monitored in real time. S4. Closed-loop force control: An edge computing module compares the pressure feedback signal from the adsorption array with a preset baseline curve in real time. The pressure feedback signal is collected by high-precision pressure sensors distributed across each adsorption unit. The preset baseline curve is dynamically generated based on parameters such as the material, size, and thickness of the ceramic plate. The vacuum level of each chamber is dynamically corrected to ensure that the adsorption force remains within a preset safety range. The correction process optimizes the correction parameters based on long-term operating data.

[0005] In the present invention, a further implementation scheme is that the S1 also includes: pre-treating the surface of the ceramic thin plate, optimizing the surface molecular activity through a plasma modification process, the plasma modification process uses a low-temperature plasma with a specific gas combination to form a nano-scale modified layer on the surface of the plate, thereby improving the surface affinity. The pretreatment process and the spectral scanning form a time-coupled collaborative operation chain, that is, the spectral scanning is started immediately after the pretreatment is completed to avoid secondary contamination of the modified surface by the external environment, and the initial state of the plate surface is recorded before pretreatment as a benchmark for evaluating the subsequent treatment effect.

[0006] In the present invention, a further implementation plan is that, in said S2, the center distance between adjacent flexible adsorption units is adaptively scaled as the thickness of the plate changes, and the force balance relationship between the adsorption units is maintained during the scaling process. The stress distribution of the rigid support frame is always within the safety threshold of the material yield limit, and the structural parameters of the frame are dynamically adjusted according to the arrangement scheme of the adsorption units, including the cross-sectional dimensions of the horizontal beams and longitudinal beams of the frame, the strength grade of the connection nodes, etc. The mechanical properties of the frame are verified by finite element analysis.

[0007] In the present invention, a further implementation scheme is that the S3 also includes: setting a progressive pressure relief channel in the edge area of ​​the ceramic thin plate, the pressure relief channel is composed of a series of throttling holes with different micropore sizes, and the boundary attenuation coefficient of the pressure field is dynamically adjustable through the microfluidic valve group. The attenuation rate can be adjusted according to the edge flatness and thickness uniformity of the ceramic thin plate to offset the adsorption force fluctuations caused by the edge effect of the plate, and the pressure changes in the edge area are monitored in real time during the pressure relief process to ensure the stability of the pressure field.

[0008] In the present invention, a further implementation plan is that in the S4, the closed-loop regulation system introduces a predictive control mechanism based on a set formed by historical adsorption data, which contains adsorption parameters and deformation data of ceramic thin plates of different materials, sizes, and surface states under various environmental conditions. The micro-deformation trend of the ceramic thin plates during the adsorption process is predicted, and the pressure compensation mechanism is triggered in advance. The compensation mechanism includes fine-tuning of the local vacuum degree, redistribution of the force of the adsorption unit, etc., to avoid damage to the plate due to excessive accumulation of micro-deformations.

[0009] In the present invention, a further implementation scheme is to also include S5, which is a bionic buffering coordination step, specifically including: at the moment the adsorption unit contacts the surface of the plate, the spatiotemporal distribution of the contact force is optimized through a hierarchical elastic structure similar to octopus tentacles, and the structure is composed of multiple layers of elastomers with different elastic moduli, and can adaptively adjust the degree of deformation according to the size of the contact pressure. The deformation response of the structure and the pressure field establish a phase-matched dynamic balance, that is, at different stages of the pressure field establishment, the deformation state of the elastic structure is adapted to it, reducing the impact force at the moment of contact, and monitoring the deformation parameters of the elastic structure in real time during the coordination process as a basis for subsequent adsorption force adjustment.

[0010] In the present invention, a further implementation plan is that in the S5, the built-in micro-displacement sensing network monitors the normal displacement changes of the plate surface in real time, and the sensor distribution density of the sensing network is differentiated according to the size and importance area of ​​the plate. When a deformation beyond the preset range is detected, the emergency pressure relief program of the local adsorption unit is automatically activated. The emergency pressure relief program includes a multi-stage pressure relief strategy, which selects different pressure relief rates and pressure relief amplitudes according to the size of the deformation variable, and at the same time issues an early warning signal to notify the relevant control system.

[0011] In the present invention, a further implementation plan is that in S3, the process of establishing the gradient negative pressure field adopts multi-physical field coupling analysis, and at the same time considers the influence of the thermophysical properties of the ceramic thin plate and the ambient humidity on the vacuum maintenance ability. The analysis process is realized through professional multi-physical field simulation, which can simulate the change law of the pressure field under different temperature and humidity conditions, and perform parameter correction through the environmental adaptation submodule. The correction parameters include the operating frequency of the vacuum generating system, the thermal insulation and moisture retention measures of the pipeline, etc., to ensure the stability of the negative pressure field in a complex environment.

[0012] In the present invention, a further implementation scheme is that the S4 also includes: when an abnormal pressure signal is detected in any unit in the adsorption array, the system automatically starts the hot backup switching of the redundant unit. The redundant unit has the same performance parameters as the main adsorption unit and is in real-time standby state. During the switching process, the continuity of the adsorption force is ensured through seamless connection, and the isolation and replacement of the faulty unit are completed without interrupting the main adsorption process. At the same time, the fault type and parameters of the faulty unit are recorded to provide data support for subsequent maintenance and optimization.

[0013] In the present invention, a further implementation plan is that the control logic of the entire adsorption process adopts a hierarchical architecture: the bottom-level execution unit is responsible for real-time force control and adjustment, including vacuum control of each adsorption unit, data acquisition and processing of pressure sensors, etc.; the middle-level decision-making unit handles the dynamic update of the characteristic map, and dynamically adjusts the adsorption strategy according to the real-time collected plate surface information and adsorption process parameters; the top-level coordination unit realizes the spatiotemporal collaboration of multiple modules, and comprehensively controls the working timing and interaction logic of the preprocessing module, sensor module, vacuum generation module, etc. The three form a control closed loop with nanosecond response through optical fiber transmission.

[0014] The beneficial effects of the present invention are: By constructing a three-dimensional feature map through multi-spectral full-area scanning in step S1, the topological planning of the adsorption array (S2) can be specifically adapted to the micro-texture, pores and defect distribution on the surface of the ceramic thin plate, avoiding the pressure concentration problem in the traditional uniform adsorption mode. Combined with the negative correlation design between the defect area and the negative pressure value in the gradient negative pressure field (S3), the plate breakage rate can be reduced, significantly improving the safety of the adsorption operation.

[0015] Closed-loop force control (S4) dynamically adjusts the vacuum level of each chamber by comparing real-time pressure feedback with a preset reference curve. Combined with the predictive control mechanism to anticipate micro-deformation trends, it can maintain the stability of adsorption force under complex working conditions such as changes in ambient temperature and humidity, and differences in plate parameters.

[0016] The progressive pressure relief channel design in S3 can specifically offset the edge effect of the plate. The microfluidic valve group dynamically adjusts the pressure decay rate to reduce the pressure fluctuation amplitude in the edge area. The bionic cushioning synergy step of S5 utilizes a hierarchical elastic structure to reduce the impact force at the moment of contact and avoid the occurrence of hidden damage.

[0017] The hierarchical control architecture achieves efficient linkage between bottom-level execution, middle-level decision-making, and top-level coordination. The nanosecond response speed of fiber optic transmission ensures the timing matching accuracy of each module reaches the microsecond level. The redundant unit hot backup switching mechanism (S4) can complete replacement within 10ms when a fault occurs, improving the stability of continuous system operation and meeting the efficiency requirements of industrial batch operations.

[0018] Through steps such as temporal coupling of pre-processing and spectral scanning (S1) and verification of framework performance by finite element analysis (S2), ineffective operations and trial-and-error costs are reduced. By optimizing correction parameters based on long-term operating data, the unit adsorption energy consumption can be reduced and the service life of the adsorption equipment can be extended. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application are clearly described below. Obviously, the embodiments described are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of this application.

[0020] This embodiment provides a method for adsorbing a ceramic thin plate, comprising the following steps: S1. Construction of surface feature maps: The surface of the ceramic sheet to be adsorbed is scanned across the entire area using a multispectral sensing unit. The multispectral sensing unit integrates visible light imaging, infrared thermal imaging, and laser methods, and can capture full-scale features from different dimensions, from nanometer-scale microtextures to millimeter-scale macro defects. Visible light imaging can clearly show surface color differences and distinct macro defect outlines, infrared thermal imaging can indirectly reflect the structural uniformity within the plate through temperature distribution, and the laser method can accurately measure the degree of fluctuation of the microtexture. The generated three-dimensional feature map contains detailed information such as the direction and density distribution of the microtexture, the size and depth parameters of the pores, and the three-dimensional coordinates and geometric morphology of multiple types of defects. The map data is stored and transmitted in an encrypted manner to ensure the integrity of the information during data transfer and prevent data leakage or tampering from affecting the accuracy of subsequent adsorption steps.

[0021] S2. Adsorption array topology planning: Based on the characteristic map, the spatial arrangement pattern of the flexible adsorption units is dynamically allocated by the distributed computing unit. The distributed computing unit can quickly process the massive data in the characteristic map and determine the optimal position of each flexible adsorption unit in combination with the overall size and shape of the ceramic plate. A force flow transmission path with a bionic mechanism is formed between the rigid support frame and the surface of the plate. This path draws on the mechanical transmission method of biological structures in nature to evenly transmit the adsorption force from each adsorption unit to the entire support frame, avoiding excessive local stress. During the planning process, the stress and strain distribution under different arrangement schemes is simulated in real time. By comparing the simulation results of different schemes, the optimal solution that can make the adsorption force distribution most uniform and the support frame force most reasonable is screened out.

[0022] S3. Establishing a gradient negative pressure field: A non-uniform pressure field is constructed in the adsorption area using a multi-chamber vacuum generation system. The system consists of several independently controlled vacuum chambers, each equipped with an independent control valve and pressure regulator. Each chamber is connected to the corresponding adsorption unit group via precision piping to ensure accurate pressure transmission. The pressure gradient is negatively correlated with the defect distribution in the characteristic map. This means that areas with dense defects correspond to lower negative pressure values ​​to prevent excessive adsorption force from causing defect expansion; areas without defects or with sparse defects correspond to higher negative pressure values ​​to ensure sufficient adsorption strength. During the pressure field establishment process, the pressure change curves of each area are monitored in real time to detect pressure anomalies and make adjustments in a timely manner.

[0023] S4. Closed-loop force control: An edge computing module compares the pressure feedback signal from the adsorption array with a preset baseline curve in real time. This module processes data locally and rapidly, reducing data transmission delays. The pressure feedback signal is collected by high-precision pressure sensors distributed across each adsorption unit, ensuring the authenticity and accuracy of the feedback data. The preset baseline curve is dynamically generated based on parameters such as the material, size, and thickness of the ceramic plate. Plates with different parameters correspond to different baseline curves. The vacuum level in each chamber is dynamically corrected to ensure that the adsorption force remains within a preset safety range. This correction process continuously optimizes the correction parameters based on long-term operating data, making the adjustment increasingly precise.

[0024] In the present invention, a further implementation scheme is that the S1 further includes: pre-treating the surface of the ceramic thin plate, optimizing the surface molecular activity through a plasma modification process, and the plasma modification process uses a low-temperature plasma with a specific gas combination to form a nano-scale modified layer on the surface of the plate. This modified layer can change the chemical properties of the surface of the plate, improve the surface affinity, and make the adsorption unit more tightly bonded to the surface of the plate. The pre-treatment process and the spectral scanning form a time-coupled collaborative operation chain, that is, the spectral scanning is started immediately after the pre-treatment is completed to avoid secondary contamination of the modified surface by dust, moisture, etc. in the external environment, thereby ensuring the accuracy of the spectral scanning results. The initial state of the plate surface is recorded before pre-treatment, including information such as the surface cleanliness and roughness, as a benchmark for evaluating the subsequent treatment effect, so as to determine whether the pre-treatment has achieved the expected effect.

[0025] In the present invention, a further implementation scheme is that in said S2, the center distance between adjacent flexible adsorption units is adaptively scaled as the thickness of the plate changes. When the plate is thicker, the center distance is appropriately increased; when the plate is thinner, the center distance is correspondingly reduced. During the scaling process, the force balance relationship between the adsorption units is maintained to ensure that the force borne by each adsorption unit is relatively balanced. The stress distribution of the rigid support frame is always within the safety threshold of the material yield limit to prevent the frame from being damaged due to excessive force. The structural parameters of the frame are dynamically adjusted according to the arrangement scheme of the adsorption units, including the cross-sectional dimensions of the crossbeams and longitudinal beams of the frame, the strength grade of the connection nodes, etc. The mechanical properties of the frame are verified by finite element analysis to ensure that the frame can work stably under various working conditions.

[0026] In a further embodiment of the present invention, S3 further comprises: providing a progressive pressure relief channel at the edge of the ceramic plate. This pressure relief channel comprises a series of orifices with varying micropore diameters. The opening and closing of these orifices are controlled by a microfluidic valve assembly, enabling dynamic adjustment of the pressure field's boundary attenuation coefficient. The attenuation rate can be adjusted based on the edge flatness and thickness uniformity of the ceramic plate. When edge flatness is poor or thickness is uneven, the attenuation rate is appropriately increased; otherwise, it is decreased. This offsets fluctuations in adsorption force caused by plate edge effects. During the pressure relief process, pressure changes in the edge region are monitored in real time, and the microfluidic valve assembly is continuously adjusted based on this feedback data to ensure pressure field stability.

[0027] In a further embodiment of the present invention, in step S4, the closed-loop regulation system incorporates a predictive control mechanism based on a collection of historical adsorption data, including adsorption parameters and deformation data for ceramic plates of varying materials, sizes, and surface conditions under various environmental conditions. By analyzing and mining this data, the system predicts the micro-deformation trends of the ceramic plates during the adsorption process and proactively triggers a pressure compensation mechanism. This compensation mechanism involves fine-tuning the local vacuum level and redistributing the force applied by the adsorption units. This prevents excessive accumulation of micro-deformations that could damage the plates, thereby improving the safety of the adsorption process.

[0028] A further embodiment of the present invention further includes S5, which is a biomimetic buffering coordination step. Specifically, at the moment of contact between the adsorption unit and the plate surface, a hierarchical elastic structure resembling an octopus tentacle is used to optimize the spatiotemporal distribution of contact force. This structure is composed of multiple layers of elastomers with different elastic moduli. The outer elastomer has a lower elastic modulus, which quickly cushions initial impact forces; the inner elastomer has a higher elastic modulus, providing stable support. The degree of deformation can be adaptively adjusted according to the magnitude of the contact pressure, with greater deformation at higher pressures and less deformation at lower pressures. The deformation response of the structure forms a dynamic equilibrium with phase matching with the pressure field establishment. That is, at different stages of the pressure field establishment, the deformation state of the elastic structure adapts to it, reducing the impact force at the moment of contact. During the coordination process, the deformation parameters of the elastic structure are monitored in real time and used as a basis for subsequent adjustment of the adsorption force, making the adjustment more tailored to the actual situation.

[0029] In a further embodiment of the present invention, in S5, a built-in micro-displacement sensor network monitors the normal displacement changes of the plate surface in real time. The sensor density of the sensor network is differentiated according to the plate size and critical areas. The sensor density is higher in the center and key deformation-prone areas of the plate, while the sensor density is lower in less critical edge areas. When deformation beyond a preset range is detected, the local adsorption unit's emergency pressure relief program is automatically activated. This emergency pressure relief program incorporates a multi-stage pressure relief strategy, selecting different pressure relief rates and amplitudes based on the magnitude of the deformation. For smaller deformations, a slower pressure relief rate and smaller amplitude are used; for larger deformations, a faster pressure relief rate and larger amplitude are used. Simultaneously, an early warning signal is issued to notify the relevant control system, allowing personnel to take timely action.

[0030] In a further embodiment of the present invention, in step S3, the establishment of the gradient negative pressure field utilizes a multi-physics coupling analysis, simultaneously considering the influence of the ceramic plate's thermophysical properties and ambient humidity on its ability to maintain vacuum. Thermophysical properties of the ceramic plate, such as thermal conductivity and thermal expansion, vary with temperature, affecting the vacuum level. High ambient humidity can also cause condensation within the pipeline, impacting vacuum stability. This analysis is accomplished through specialized multi-physics simulation, simulating the pressure field's dynamics under varying temperature and humidity conditions. The environmental adaptation submodule then modifies parameters, including the vacuum generation system's operating frequency and the pipeline's thermal insulation and moisture retention measures, to ensure the stability of the negative pressure field in complex environments and enhance the adsorption method's adaptability.

[0031] In the present invention, a further implementation scheme is that S4 also includes: when an abnormal pressure signal is detected in any unit in the adsorption array, the system automatically initiates hot backup switching of the redundant unit. The redundant unit has the same performance parameters as the main adsorption unit and is in real-time standby state, capable of replacing the faulty unit in a short time. During the switching process, the continuity of the adsorption force is ensured through seamless connection, avoiding the impact of sudden changes in adsorption force due to unit switching on the stability of the plate. The faulty unit is isolated and replaced without interrupting the main adsorption process. At the same time, the fault type and parameters of the faulty unit are recorded, including information such as the time of failure and abnormal pressure values. This provides data support for subsequent maintenance and optimization, facilitating staff to analyze the cause of the failure and improve equipment performance.

[0032] In the present invention, a further implementation scheme is that the control logic of the entire adsorption process adopts a hierarchical architecture: the bottom-level execution unit is responsible for real-time force control and adjustment, including vacuum control of each adsorption unit, data collection and processing of pressure sensors, etc., to ensure the precise execution of various specific operations; the middle-level decision-making unit handles the dynamic update of the characteristic map, and dynamically adjusts the adsorption strategy based on the real-time collected plate surface information and adsorption process parameters, so that the adsorption method can adapt to the real-time state changes of the plate; the top-level coordination unit realizes the spatiotemporal coordination of multiple modules, comprehensively controls the working sequence and interaction logic of the pre-processing module, sensor module, vacuum generation module, etc., to ensure tacit cooperation between the modules. The three form a control closed loop with nanosecond response through optical fiber transmission, ensuring the high speed and accuracy of information transmission, and improving the response speed and work efficiency of the entire adsorption system.

[0033] This adsorption method for ceramic thin plates forms a complete and efficient adsorption system through the synergistic action of multiple steps. From S1, which comprehensively captures the surface features of the ceramic thin plates, leveraging the various imaging methods of the multispectral sensing unit to provide accurate basic data for subsequent steps; to S2, which implements feature-based adsorption array planning, utilizing distributed computing units and a biomimetic force flow transmission path to ensure the rationality of the adsorption unit layout and the stability of the support frame; to S3, which precisely establishes the gradient negative pressure field, achieving a reasonable distribution of adsorption force through the design of a multi-chamber vacuum generation system and the correlation of pressure gradient and defect distribution; and S4, which implements closed-loop force control regulation, relying on edge computing modules and dynamic correction mechanisms to ensure that the adsorption force is always within a safe range. Each step is closely linked and interconnected, acting together to contribute to the adsorption process of the ceramic thin plates.

[0034] In a further implementation plan, the pretreatment step of S1 enhances the affinity between the plate surface and the adsorption unit through a plasma modification process, and the time-coupled collaborative operation chain ensures the effects of pretreatment and spectral scanning, providing better prerequisites for subsequent adsorption; the adaptive scaling of the center distance of the adsorption unit and the dynamic adjustment of the frame structure parameters in S2, combined with the verification of finite element analysis, ensure the adaptability and structural stability of the adsorption system to plates of different thicknesses, so that the adsorption system can cope with various specifications of ceramic thin plates; the progressive pressure relief channel design of S3, through the adjustment of the microfluidic valve group, effectively solves the problem of adsorption force fluctuation caused by edge effect, ensures the overall stability of the pressure field, and allows the edge area of ​​the plate to be stably adsorbed; the predictive control mechanism of S4 predicts micro-deformation trends based on historical data and takes compensatory measures in advance, while the redundant unit switching ensures the continuity of adsorption force when a fault occurs, greatly improving the reliability of the adsorption process from the perspectives of preventing deformation and responding to faults.

[0035] The newly added S5 biomimetic cushioning coordination step mimics the hierarchical elastic structure of an octopus's tentacles. By combining multiple layers of elastomer composites with varying elastic moduli and deformation monitoring, it further reduces the impact force at the moment of contact, providing more comprehensive protection for the brittle ceramic sheets and minimizing potential damage during contact. The application of multi-physics coupling analysis in S3 comprehensively considers the thermophysical properties of the ceramic sheets and the influence of ambient humidity. By modifying the parameters of the environmental adaptation submodule, the method adapts to complex and changing environmental conditions. The hierarchical control architecture employed throughout the entire process clarifies the responsibilities of bottom-level execution, mid-level decision-making, and top-level coordination. Through the high-speed response of fiber-optic transmission, the modules achieve efficient and coordinated operation, comprehensively improving the safety, stability, and adaptability of the ceramic sheet adsorption operation.

[0036] The above embodiments are described. In the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary personnel in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.

At the same time, the fault type and parameters of the faulty unit are recorded to provide data support for subsequent maintenance and optimization.

10. The method for adsorbing ceramic thin plates according to any one of claims 1 to 9, characterized in that: The control logic of the entire adsorption process adopts a hierarchical architecture: the bottom-level execution unit is responsible for real-time force control, including vacuum control of each adsorption unit, data collection and processing of pressure sensors, etc. The middle-level decision-making unit handles the dynamic update of the characteristic map and dynamically adjusts the adsorption strategy based on the real-time collected plate surface information and adsorption process parameters; the top-level coordination unit realizes the spatiotemporal collaboration of multiple modules, and comprehensively controls the working timing and interaction logic of the preprocessing module, sensing module, vacuum generation module, etc. The three form a control closed loop with nanosecond response through optical fiber transmission.
