[0062] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] Example:

[0064] Please see attached Figure 1 - Attachment Fig.10 , an embodiment of the present invention provides a resin flow control system in a carbon fiber plate vacuum infusion process, comprising:

[0065] The central processing module is responsible for coordinating and controlling the operation of each submodule. It is used to collect sensor data in real time, perform local data processing and control decisions, and can achieve precise control of the resin flow process, ensure real-time integration and processing of data from each module, optimize the infusion process, and improve the overall quality and production efficiency of the product.

[0066] The vacuum control module controls and adjusts the vacuum environment to ensure that the resin infusion process is carried out under the set vacuum conditions. By maintaining a stable vacuum environment, air is prevented from entering the infusion area, thereby preventing bubbles from being generated and improving the quality of the final product.

[0067] The bubble treatment module is used to identify bubbles generated during the resin flow process and perform defoaming treatment through ultrasonic waves. The cavitation effect of ultrasonic waves eliminates bubbles, thereby ensuring the uniformity of the resin and avoiding product strength reduction and surface defects caused by bubbles.

[0068] The infusion detection module monitors the key parameters of the resin during the infusion process in real time, including pressure, temperature and flow rate. Through real-time monitoring, the infusion parameters are dynamically adjusted to ensure that the resin flows in the best state and avoid uneven infusion or excessive flow.

[0069] The perfusion control module accurately controls the pressure, temperature and flow rate during the perfusion process according to the data provided by the detection module. By controlling these key parameters, the perfusion control module can ensure the stability and controllability of the perfusion process, thereby improving the perfusion quality and reducing the scrap rate;

[0070] The flow control module is used to adjust the flow direction, flow rate and flow angle of the resin to ensure the uniform distribution of the resin in the mold. By accurately adjusting the flow direction, flow rate and angle, the module can ensure that the resin evenly covers every area of ​​the mold to avoid gaps or dead corners, thereby improving the consistency and quality of the product;

[0071] The operation storage unit provides an operation interface, displays system information, and receives user input commands. The operator can use this unit to monitor the system status in real time and make necessary operational adjustments. It also records and stores operational data for subsequent analysis and tracking.

[0072] Remote communication module, which enables communication between the system and external devices or control centers through wireless connection. Through the remote communication module, the system can realize remote monitoring and operation, improve the management efficiency and operational flexibility of the system, especially in large-scale production environments, to achieve centralized management and real-time response;

[0073] Remote control terminal, by providing an interface for remote operating system and issuing an alarm when abnormal situation occurs, users can monitor the system status in real time at any location, handle abnormal situation in time, and ensure the continuity and safety of the production process;

[0074] Please see attached Figure 1 - Attachment Figure 2 , the central processing module includes;

[0075] Data integration unit: The main function of the data integration unit is to collect and integrate data from various detection modules and monitor different process parameters in real time, such as vacuum degree, pressure, temperature and flow rate;

[0076] The data processing unit generates optimization and provides real-time feedback and adjustments through the adaptive control algorithm. The adaptive control algorithm first collects data from various detection modules in real time through the data integration unit, and identifies possible process deviations or abnormalities by calculating the deviation between the current process parameters and the ideal parameters in real time. According to the size and nature of the deviation, the adaptive control algorithm automatically adjusts the control parameters. Specific adjustments may include: increasing pressure to increase flow rate, lowering temperature to improve resin fluidity, or adjusting vacuum to avoid bubble generation. After each adjustment, the current state will be re-evaluated and the control parameters will be further optimized. This feedback loop enables the system to continuously adjust itself to cope with complex process conditions and external disturbances;

[0077] The decision control unit analyzes the results provided by the data processing unit, combines the current process requirements and objectives of the system, and makes control decisions through preset control logic or rules.

[0078] Please see attached Figure 1 and attached Figure 3 , the vacuum control module includes;

[0079] The vacuum detection unit continuously detects the vacuum degree and provides real-time and accurate vacuum degree data, enabling the system to quickly respond to any changes in the vacuum environment. Through this real-time monitoring, the system can avoid abnormal resin flow caused by unstable vacuum degree and ensure the smooth progress of the infusion process;

[0080] The leak detection unit monitors whether there is a leak and ensures the stability of the vacuum environment. It identifies possible leaks by analyzing the abnormal changes in the vacuum degree. When the vacuum degree continues to drop and cannot be restored, the leak detection unit will identify it as a potential leak problem.

[0081] The vacuum regulating unit automatically adjusts the vacuum degree according to the detection results to maintain the set vacuum level. The operating state of the vacuum pump is adjusted through the automatic controller. When the vacuum detection unit or the leakage detection unit detects that the vacuum degree deviates from the set value, the vacuum regulating unit will respond immediately by increasing or decreasing the power of the vacuum pump or adjusting the valve opening to quickly restore the vacuum degree to the preset range.

[0082] Please see attached Figure 1 and attached Figure 4 , the above-mentioned bubble processing module includes:

[0083] The bubble detection unit monitors whether bubbles are generated during the resin flow process. The sensor will detect the presence of bubbles by capturing the sound waves inside the resin. After detecting bubbles, the sensor converts this information into electronic signals and transmits them to the data integration unit of the central processing module for analysis and processing in real time.

[0084] The ultrasonic defoaming unit uses the cavitation effect of ultrasound to eliminate bubbles in the resin. When the bubble detection unit finds the presence of bubbles, the system activates the ultrasonic defoaming unit. The ultrasonic defoaming unit emits high-frequency ultrasound, which propagates in the resin to generate high-frequency vibrations and tiny cavitation bubbles. These cavitation bubbles will cause local pressure changes, causing the bubbles in the resin to gradually burst and disappear, and eventually make the resin reach a uniform state.

[0085] Please see attached Figure 1 and attached Figure 5 ,The perfusion detection module includes;

[0086] The pressure detection unit detects the pressure value inside the system in real time during the infusion process through a high-precision pressure sensor installed at a key position of the system, providing real-time data to prevent uneven resin flow caused by pressure fluctuations;

[0087] The temperature detection unit monitors the temperature of the resin. Through multiple temperature sensors, it monitors the temperature of the resin and the environment in the system in real time. These sensors can be installed at different key points to ensure that the resin maintains optimal fluidity and viscosity during the infusion process, thereby preventing problems such as uneven infusion and too long or too short curing time due to abnormal temperature;

[0088] The flow rate detection unit measures the flow rate of the resin. Through the flow sensor installed in the resin flow path, the flow rate of the resin is monitored in real time, ensuring that the resin can flow at a uniform and appropriate speed throughout the entire infusion process, thereby avoiding local excess or deficiency during the infusion process.

[0089] Please see attached Figure 1 and attached Figure 6 , the perfusion control module includes;

[0090] The pressure control unit adjusts and maintains the stability of the pressure during the perfusion process. It works in conjunction with the pressure detection unit to monitor the pressure value in the system in real time. When it detects that the pressure deviates from the preset range, the pressure control unit automatically adjusts the output of the vacuum pump or pressurizing device to restore and maintain the set ideal pressure value, ensuring the pressure stability during the perfusion process and reducing problems such as uneven flow, insufficient penetration or excessive penetration caused by pressure fluctuations.

[0091] The temperature control unit controls the temperature of the resin. By working in conjunction with the temperature detection unit, it monitors the temperature of the resin and the system environment in real time. When the temperature deviates from the set optimal range, the temperature control unit automatically adjusts the output of the heater or cooler to ensure that the resin is always within the most suitable temperature range, ensuring that the fluidity and viscosity of the resin during the infusion process are in the best state, thereby preventing problems such as uneven infusion and too long or too short curing time caused by abnormal temperature, and improving the molding quality and consistency of the product;

[0092] The flow rate control unit monitors the flow rate of the resin in real time by working in conjunction with the flow rate detection unit. When the flow rate is detected to deviate from the preset range, the flow rate control unit will automatically adjust the working state of the resin pump or flow control valve to restore and maintain the ideal flow rate, ensuring the uniform distribution and stable flow of the resin throughout the infusion process, thereby reducing the formation of bubbles and uneven filling problems, and ensuring the quality consistency and structural integrity of the product.

[0093] Please see attached Figure 1 and attached Figure 7 , the flow path control module includes;

[0094] The flow direction detection unit uses detection equipment to accurately capture the flow path of the resin. If it detects that the resin flow direction deviates from the preset path, the system will adjust the flow rate and flow velocity in time to correct the flow direction, ensuring that the resin can smoothly fill all parts of the mold. This ensures that the resin flows in the mold according to the designed path, preventing flow dead corners or insufficient filling caused by incorrect flow direction.

[0095] The flow control unit, through linkage with the flow rate control unit, adjusts the opening of the resin pump or flow control valve in real time to control the flow of resin. The system dynamically adjusts the flow rate according to the needs of the mold and real-time flow direction detection data to ensure that the resin can flow in an appropriate amount, avoiding overflow caused by excessive flow or insufficient filling caused by too little flow;

[0096] The angle control unit adjusts the angle of resin flow so that the resin can flow at the set angle. The system automatically adjusts the flow angle according to the shape and structural complexity of the mold to ensure that the resin can smoothly enter hard-to-reach areas or complex geometric structures, and ensure that the resin can fully cover and fill all parts of the mold. Especially for molds with complex shapes or diverse internal structures, the angle control unit can significantly improve the accuracy of infusion and the overall quality of the product.

[0097] Please see attached Figure 1 and attached Figure 8 ,The operation interaction module includes;

[0098] The information display unit displays the system status and various parameters in real time, allowing the operator to intuitively understand the progress of the current infusion process and the overall health status of the system. This information includes important data such as pressure, temperature, flow rate, vacuum degree, resin flow direction, etc.

[0099] Command input units, through which operators can input control commands, such as adjusting parameter settings such as pressure, temperature, flow rate, or selecting different operating modes. The input commands are transmitted in real time to the central processing module, which parses and executes the commands to ensure that the system is adjusted or operated according to user requirements;

[0100] The data storage unit records and stores operation data and historical records. By connecting to the central processing module, it continuously records the real-time data and operation logs of the system. The stored data is classified and stored in the system database, and can be retrieved and viewed at any time as needed. The data storage unit also supports data backup and export functions to ensure data security and traceability.

[0101] Please see attached Figure 1 and attached Fig. 9 , the remote communication module includes;

[0102] Wireless connection unit, wireless connection with external devices, ensures that the system can communicate with remote terminals in real time;

[0103] The information transmission unit is responsible for the transmission of data and instructions, ensuring that the remote operation instructions can be delivered to the system quickly and accurately, and feeding back the system's operating status and real-time data to the remote terminal.

[0104] Please see attached Figure 1 and attached Fig.10 , the remote control terminal includes;

[0105] The user operation unit receives control instructions input by the user on the remote terminal through a wireless connection with the remote communication module, so that the operator can control the system in real time at any remote location without having to operate on site;

[0106] The abnormal alarm unit is connected to each monitoring module of the system in real time to continuously monitor the operating status of the system. When a parameter is detected to be out of the normal range or the system fails, the alarm unit will immediately trigger the alarm mechanism. The alarm information is sent to the user's remote terminal through the remote communication module to remind the user in the form of sound, vibration or notification;

[0107] The information receiving and displaying unit obtains real-time operation data and status information from the system through the information transmission unit, providing users with a real-time, visual system monitoring tool so that users can fully grasp the current status and historical operation data of the system.
