Technical Field

[0001] The invention relates to the technical field related to welding control, and in particular to a welding process for insulator leads of tantalum capacitors. Background Art

[0002] Tantalum capacitors are widely used in electronic devices, and their welding quality directly affects the performance and stability of capacitors. During the welding process of tantalum capacitors, it is usually necessary to accurately control parameters such as temperature, pressure and time to ensure the quality of each welding point. However, due to the multiple dynamic factors involved in the welding process, the precise control of temperature, pressure and time has always been a technical problem in the industry.

[0003] In the prior art, the welding process is usually controlled by a simple temperature control system and pressure regulating equipment. These systems ensure the consistency and stability of the welding points by setting fixed welding parameters, but since the characteristics of the materials and environmental conditions may change during the welding process, fixed parameters often cannot adapt to complex working conditions. The main problems include: 1. It is difficult to find the best balance between temperature control and pressure control. Excessive temperature or pressure may cause poor welding or damage to the capacitor; 2. The temperature and pressure fluctuate greatly during the welding process, affecting the consistency of welding quality and resulting in a high rate of defective products; 3. As the equipment ages and environmental conditions change, the control of welding parameters needs to be adjusted in real time, and the prior art cannot achieve precise dynamic adjustment.

[0004] In order to deal with the above problems, the industry has adopted solutions to improve the accuracy of temperature control and pressure control, such as introducing advanced PID control algorithms and automatic feedback systems, but these systems are often costly and difficult to adapt to dynamic changes. Although these technologies have improved welding quality, they have not yet fully solved the problem of balancing temperature control and pressure control, especially under complex environmental conditions.

[0088] The predicted defect probability value output by the model is fed back to the central processing unit for real-time adjustment of welding parameters to ensure welding quality;

[0089] Step 5, data fusion and Kalman filtering:

[0098] Embodiment 1:

[0099] This embodiment uses the tantalum capacitor lead welding process as an application scenario to demonstrate the specific implementation of the technical solution of the present invention. In the traditional welding process, due to changes in temperature, pressure and time, the welding quality is easily affected by factors such as environmental changes and material differences, resulting in inconsistent welding point quality and affecting the reliability of the final product. In order to solve this problem, this embodiment adopts a dynamic control system based on sensor feedback, combined with a machine learning algorithm for optimization, to ensure high precision and high efficiency of the welding process.

[0100] In specific applications, the system monitors multiple parameters in the welding process in real time through integrated temperature, pressure and humidity sensors. When the welding environment or material properties change, the central processing unit receives sensor data and adjusts the welding temperature and pressure through the PID control algorithm. At this time, all variables in the welding process will be optimized through the adaptive adjustment mechanism, thereby avoiding the negative impact of overheating, overpressure and other problems on the welding point. At the same time, the machine learning algorithm uses historical data and real-time feedback data to predict possible defects in the welding process and automatically adjusts parameters, avoiding errors caused by manual intervention and ensuring the high quality of each welding point.

[0101] Specifically, the system can also adjust the welding parameters in real time according to the aging of the equipment and the dynamic changes of the external environment (such as humidity changes, ambient temperature fluctuations, etc.), thereby improving the adaptability of welding. For example, in an environment with high humidity, the system automatically extends the heating time and adjusts the pressure to ensure the consistency of welding quality. This technology effectively improves welding efficiency, reduces the occurrence of defective products, and significantly reduces production costs during the production process; through this embodiment, the technical solution demonstrates how to achieve a dual improvement in quality stability and production efficiency during the welding process through multi-parameter dynamic control and adaptive feedback mechanism, solving the problems of difficult control and high defect rate in traditional welding processes.

[0102] Embodiment 2:

[0103] This embodiment demonstrates the significant advantages of this technical solution in the welding process of tantalum capacitors through comparative experiments. In traditional welding processes, due to the large range of temperature and pressure changes, it is difficult to maintain consistent welding quality, and the incidence of welding defects is high. In order to verify the technical effect of the present invention, we designed a comparative experiment, using the traditional welding method and the multi-parameter dynamic control system of the present invention for welding, and tested and recorded various parameters during the welding process.

[0104] Experimental data show that when using traditional welding methods, the welding quality fluctuates greatly and the electrical performance of the welding points generally decreases. Specifically, when the ambient temperature changes greatly, the welding defect rate of the traditional method is 10.5%. In contrast, the welding system using this technical solution successfully reduces the defect rate to 3.2% by real-time monitoring of temperature, pressure and other parameters, and adjusting the welding conditions in real time according to feedback data, thereby improving the stability and consistency of welding quality.

[0105] In addition, this technical solution has significantly improved welding efficiency. By introducing machine learning algorithms to optimize welding parameter adjustment, this system not only reduces the generation of defective products, but also shortens the welding cycle by about 15%, thereby improving overall production efficiency. More importantly, with the application of the system's automatic adjustment function, a large amount of manual intervention is not required during the production process, which further reduces the error rate of operation and effectively reduces production costs.

[0106] In the actual production process, in an environment with large temperature fluctuations, such as welding, the temperature near the welding area fluctuates greatly. It is difficult for traditional welding methods to maintain consistency. This system ensures that each welding meets high quality standards by flexibly adjusting parameters. In addition, the system's adaptive adjustment mechanism for equipment aging also provides a guarantee for long-term stable operation.

[0107] Embodiment 3:

[0108] This embodiment describes in detail how to ensure accurate control of various parameters in the welding process to improve welding quality and consistency through dynamic adjustment of heating / cooling rate, welding time and pressure. At the same time, the details of the machine learning algorithm and the specific implementation path of the pressure adjustment function are further described.

[0109] This embodiment uses multiple sensors to monitor key parameters such as temperature, pressure, and time during the welding process in real time. These sensors include temperature sensors, pressure sensors, timers, etc., which can feed back data to the central processing unit in real time during the welding process. The temperature sensor monitors the temperature of the welding area in real time and feeds back the data to the central processing unit. Set the target temperature T target With real-time temperature T current The difference ΔT will be used to adjust the heating power. The pressure sensor monitors the pressure in the welding area in real time to ensure that the applied pressure is uniform. Through the feedback of pressure data, the central processing unit can adjust the pressure in real time to ensure the stability of the weld.

[0110] The adjustment of the heating rate is determined based on the real-time temperature difference ΔT and the thermal characteristics of the welding material. The central processing unit calculates the heating power P using the PID control algorithm based on the difference between the real-time temperature of the welding area and the set target temperature. The adjustment formula for the heating power P is: Where Q is the amount of heat transferred, t is the heating time, and ΔT is the temperature difference. This formula is based on the principles of thermodynamics and can accurately control the heating process. Heating rate R heat Calculated by the following formula: Where m is the mass of the welding material and C is the specific heat capacity of the welding material. The real-time temperature is combined with the thermal characteristics of the welding material to dynamically adjust the heating power, thereby achieving precise control.

[0111] Welding time t weld Dynamic adjustment based on temperature difference and heating rate. Based on the difference between the real-time temperature and the target temperature, the required welding time is calculated to ensure that the heat input during the welding process meets the predetermined standard; the welding time is calculated using the following formula: Among them, T target To set the target temperature, T current is the real-time temperature, R heat is the heating rate. This formula dynamically adjusts the welding time based on the relationship between the real-time temperature difference and the heating rate.

[0112] During welding, the applied pressure is adjusted by real-time feedback of the pressure sensor data. The pressure adjustment is based on the real-time temperature and pressure sensor data, using the function f(T current , T target , P sensor) to calculate the required applied pressure.

[0113] The pressure regulation function f is based on the real-time temperature difference ΔT and the real-time pressure sensor data P sensor Adjust the applied pressure. The function is as follows: P pressure =α·ΔT+β·P sensor +γ, where α, β, and γ are coefficients obtained by fitting historical experimental data, representing the influence of temperature changes and pressure sensor feedback data on the applied pressure. This formula is fitted by regression analysis or machine learning algorithms (such as support vector machines (SVM), neural networks (DNN), etc.) to ensure that the pressure applied under different welding conditions can be automatically adjusted according to real-time data. The machine learning model is trained by inputting historical experimental data and data from the real-time welding process to optimize the coefficients of the pressure regulation function. During the training process, the coefficients α, β, and γ are adjusted using the gradient descent method or other optimization algorithms to obtain the optimal pressure regulation function. After the model training is completed, the model is input with real-time welding data (such as temperature changes, pressure feedback, etc.) to calculate the required pressure value to ensure that the pressure applied during the welding process meets the predetermined standards, thereby improving the welding quality.

[0114] This embodiment also introduces a machine learning model (such as SVM, DNN, etc.) to optimize various parameters in the welding process. By training the historical data of the welding process, the model can predict welding defects and adjust parameters such as heating, pressure and time according to the prediction results. The optimization process is as follows: the machine learning model adjusts the welding parameters through real-time data input, reduces welding defects and improves the quality of solder joints.

[0180] Among them, T target To set the target temperature, T current is the real-time temperature, R heat is the heating rate. This formula ensures that the welding time is dynamically adjusted according to the real-time temperature difference and heating rate, thereby accurately controlling the heat input during the welding process.

[0181] Moreover, in the extended implementation, machine learning optimization and welding defect prediction can be used, that is, this embodiment uses a machine learning algorithm to predict the defects that may occur during the welding process, and adjusts the welding parameters in real time according to the prediction results.

The model predicts the probability of welding defects and adjusts parameters such as temperature, pressure and welding time in real time to avoid the occurrence of welding defects.

[0184] At the same time, in order to improve the control accuracy during the welding process, this embodiment combines multi-sensor data (temperature, pressure, humidity, etc.) and optimizes the welding parameters through the Kalman filter algorithm. The specific steps are as follows: Kalman filter prediction formula:

The whole system can automatically adjust the various parameters in the welding process according to the changing environmental conditions and the characteristics of the welding materials to ensure the stability and consistency of the welding quality. And through the above-mentioned optimization scheme, the temperature, pressure and time in the welding process can be accurately controlled in a dynamic environment to avoid quality fluctuations caused by environmental changes and equipment aging; after introducing machine learning and Kalman filter technology, the defect prediction and real-time adjustment in the welding process greatly improve the consistency and stability of welding quality; the automatic adjustment system reduces the intervention of human operation, reduces the risk of human error, and improves production efficiency and product reliability.
