[0036] In the related art, the inspection of tin-plating equipment often relies on regular manual inspection or only conducts inspection after the tin-plating equipment has obvious quality problems. Manual inspection cannot discover problems in real time and is prone to omissions, which makes it more likely that small faults will continue to accumulate in the long-term operation of the tin-plating equipment, eventually leading to failure or shutdown of the tin-plating equipment.

[0037] To solve the above problems, the embodiments of the present application provide a method, system and device for intelligently controlling the tinning process of tinned copper wire. In the method, by receiving tinning operation data and enabling the tinning equipment to tin the copper wire based on the tinning operation data, the tinning operation can be automatically completed according to the instructions, thereby reducing manual intervention and quality problems caused by human operation errors. Self-test data is generated based on tinning operation data, so that the working conditions of various parts of the equipment can be monitored in real time, and the key parameters of the tinning equipment can be dynamically monitored, and preventive maintenance can be performed to reduce sudden failures; the execution instruction of the self-test mode indicated by the self-test data is received, and the tinning equipment automatically detects and obtains the test data. Under the execution instruction of the self-test mode indicated by the self-test data, the tinning equipment can be detected in real time to prevent small faults from accumulating into large faults, and automatic detection can be performed according to the operation of the tinning equipment, so as to improve the automation process, reduce manual intervention and thus improve the tinning capacity of the tinning equipment; the tinning parameters corresponding to the sub-components with tinning defects indicated by the test data are adjusted, and the adjusted tinning parameters are used to control the tinning equipment to tin the copper wire, so that problems can be discovered in real time to control the tinning quality within a stable range, so that each batch of tinned copper wires meets the quality standards, reduces the defective rate, shortens the adjustment time, and improves production efficiency.

[0038] The intelligent control method for the tinning process of tinned copper wire provided in the embodiment of the present application can be applied to the intelligent control device for the tinning process of tinned copper wire. At this time, the intelligent control device for the tinning process of tinned copper wire is the executor of the intelligent control method for the tinning process of tinned copper wire provided in the embodiment of the present application. The embodiment of the present application does not impose any restrictions on the specific type of the intelligent control device for the tinning process of tinned copper wire.

[0039] For example, the intelligent control equipment for the tinning process of tinned copper wire includes a tinning device and a control device; the tinning device and the control device are connected in communication or the control device is installed in the tinning device. The tinning device includes a plating tank, an anode, a cathode, a power system, a filtration system, a heating system and a cooling system; the plating tank is the core component of the tinning equipment and is used to hold the tinning solution. The plating tank is made of corrosion-resistant materials, such as plastic (polyvinyl chloride, polypropylene, etc.) or fiberglass, and the shape and size of the plating tank are determined according to the size and output requirements of the plated parts. The material of the anode is usually tin with high purity. During the electroplating process, the tin of the anode will continuously dissolve into the tinning solution to replenish the consumption of tin ions in the solution. There are many shapes and installation methods of the anode, for example, the plate-shaped anode can be installed vertically or obliquely on both sides of the plating tank so that there is a suitable current distribution between the plated parts. The cathode is used to hang the workpiece to be tinned, and the plated parts need to be fully in contact with the tinning solution and form a uniform current distribution on the surface of the plated parts. The hanger is made of metal materials with good conductive properties, such as copper or copper alloy, and the surface needs to be insulated to prevent the hanger itself from being tinned during the tinning process. The power supply system is used to provide the DC power required for electroplating. The output voltage and current of the power supply can be adjusted according to the requirements of the tinning process. The voltage of tinning is relatively low, ranging from a few volts to more than ten volts, and the current depends on the area of ​​the plated parts and the speed requirements of tinning. For example, for small-area plated parts, the output current of the power supply is between a few amperes and tens of amperes; for batch tinning of large-area plated parts, the power supply needs to be able to provide a larger current, reaching hundreds of amperes or even higher. The filtration system is used to filter impurities in the tinning solution. During the use of the tinning solution, metal chips, dust and other impurities may be mixed in, and the impurities will affect the quality of tinning. The filtration system includes a filter and a circulation pump. The tinning solution is extracted from the plating tank by the circulation pump, filtered by the filter, and then sent back to the plating tank to keep the tinning solution clean. The filter element of the filter is generally made of filter paper, filter mesh or ceramic materials, which can filter out impurities of different particle sizes. The heating system is used to heat the tinning solution to a suitable working temperature, and an electric heating rod or a heat exchanger can be used. The cooling system is used to cool the tinning solution when the temperature is too high to prevent the composition of the tinning solution from changing or the quality of the plated parts from decreasing. The cooling method can be an air-cooled radiator or a water-cooled device. In some high-precision tinning equipment, a water-cooling system is used to accurately control the temperature of the tinning solution by circulating cooling water. The control device can be a terminal device such as a tablet computer, a laptop computer, a desktop computer, a smart screen, a smart TV, a computing device, a laptop computer, a handheld computing device or a computer.

[0040] In order to better understand the intelligent control method for the tinning process of tinned copper wire provided in the embodiment of the present application, the specific implementation process of the intelligent control method for the tinning process of tinned copper wire provided in the embodiment of the present application is exemplarily introduced below.

[0041] Figure 1A schematic flow chart of an intelligent control method for a tinned copper wire tinning process provided by an embodiment of the present application is shown. The intelligent control method for a tinned copper wire tinning process comprises:

[0042] S100, receiving tinning operation data, and causing a tinning device to tin the copper wire based on the tinning operation data; wherein the tinning operation data is used to indicate a work instruction for the tinning work of the copper wire.

[0043] It is understood that the tinning operation data used to indicate the work instructions for the tinning of copper wires may include the tinning process parameter settings and equipment operations. The tinning process parameter settings may include the values ​​of the composition and concentration of the plating solution, the value of the plating solution temperature (different tinning processes have different suitable temperature ranges, for example, the temperature of the alkaline tinning solution is usually controlled at 70-90°C, and the temperature of the acidic tinning solution may be 5-30°C) and the current density value. For example, in the process of electroplating tin, the current density can be set at 1-5A / dm 2 The equipment operation may include a plating tank stirring method (stirring may be performed using a stirring paddle) and a stirring speed, and the stirring paddle may rotate at a speed of 100-200 rpm.

[0044] For example, the tinning operation data can be received through serial communication; the serial communication can connect the device storing the tinning operation data with the tinning device through a serial line such as RS232 or RS485, and then encode the tinning operation data according to the serial communication protocol, such as setting parameters such as baud rate, data bit, stop bit, etc., and then send it out through the serial port. At the tinning device end, the data is received and decoded through the serial port receiving module, and the parsed operation data is transmitted to the control system of the tinning device to realize the control of the tinning device.

[0045] S200, generating self-test data according to the tinning operation data; wherein the self-test data is used to indicate a self-test mode of the tinning equipment, and the self-test mode is a mode for automatically testing the tinning equipment during the tinning process.

[0046] It can be understood that after a long period of work, the self-test mode includes checking the sealing of the tinning tank, detecting the temperature of the tinning solution, checking whether the current and voltage between the electrodes meet the set process parameters, checking the status of the fuse, and checking the tension value of the conveyor belt.

[0047] Exemplarily, self-test data can be generated according to the frequency of the tinning operation data; wherein the frequency is the frequency or number of times the work instructions indicated by the tinning operation data are sent to the tinning equipment per unit time, and the unit time can be 1h, 2h or 5h, etc.

[0048] In one possible implementation, see Figure 2 , S200, generates self-test data based on tinning operation data, including:

[0049] S210, detecting the startup data of the tin-plating equipment according to the work instructions indicated by the tin-plating operation data; wherein the startup data is used to indicate the time point when the tin-plating equipment starts the tin-plating work.

[0050] It can be understood that the time point indicated by the startup data is the time point when the tinning equipment is just started. According to the work instructions indicated by the tinning operation data, the time point when the tinning equipment starts tinning is detected. The detection method can be through the built-in timing function of the tinning equipment. The timing function is when the tinning equipment is started, such as when the key actions such as turning on the power of the tinning tank to send the workpiece to be tinned into the tinning tank occur, the timer starts working, and the timer can accurately record the time from the start of the tinning process to the end, and the tinning start time is the moment when the timer starts. For example, in an automated continuous tinning production line, when the operator issues a "start tinning" instruction through an operation panel or a terminal device (such as a mobile phone or computer that can remotely control the tinning equipment), it will simultaneously trigger the tinning tank electrode power-on, the tinning liquid stirring device is turned on, and the conveyor belt is started, and the built-in timer is activated. At this time, the initial time point recorded by the timer is the time point when the tinning equipment starts tinning.

[0051] S220, obtaining current time data; wherein the time data is used to indicate the current time point.

[0052] It can be understood that the current time point indicated by the time data is any time point after the tinning equipment starts the tinning work and before the tinning equipment completes the work.

[0053] Exemplarily, the current time data is obtained according to the working intensity of the tinning equipment; the working intensity may include the number of tinned workpieces, the tinning layer thickness requirement and the complexity, that is, the more the number of tinned workpieces, the higher the tinning layer thickness requirement and the more complex the complexity, the higher the working intensity; for example, the tinning equipment starts working at 8:30 in the morning and is expected to be completed at 5:30 in the afternoon, then the time points between 8:31 and 5:29 are all the current time points indicated by the time data, which may be 9:00 in the morning, 10:00 in the morning, 11:00 in the morning, 2:00 in the afternoon, 3:00 in the afternoon or 4:00 in the afternoon, which can be determined according to the working intensity of the tinning equipment. When the working intensity of the tinning equipment is high, the interval can be 1 hour or 1.5 hours, that is, the current time point indicated by the time data is 9:30 in the morning or 10:00 in the morning, and the working intensity of the tinning equipment can be spaced at intervals of 3 or 4 hours, that is, the current time point indicated by the time data is 11:30 in the morning or 12:30 in the morning, etc.

[0054] S230, performing data analysis on the startup data and the time data to obtain working time data; wherein the working time data is used to indicate the working time of the tinning equipment.

[0055] Exemplarily, the current time point indicated by the time data minus the time point when the tin-plating equipment starts tin-plating work indicated by the startup data is subtracted to obtain the duration value, and the duration value is determined as the working time data; the formula is G=SQ, and the unit is min; that is, G is the working time data, S is the time data, and Q is the startup data; for example, the current time point indicated by the time data is 10 am, and the time point when the tin-plating equipment starts tin-plating work indicated by the startup data is 7 am, then according to the formula G=SQ, that is, 10-7=3h, that is, G=3h=180min; therefore, the working time of the tin-plating equipment indicated by the working time data is 180min.

[0056] S240, generating self-checking data according to the working time data.

[0057] Exemplarily, self-test data is generated according to the working hours of the tin-plating equipment indicated by the working time data; wherein, the self-test data can be generated according to the total working hours of the tin-plating equipment, or the self-test data can be generated according to the total working hours and the working intensity; if the self-test data is generated according to the tin-plating time, for example, the total working time is 12 hours, the self-test data can be generated in 3 or 4 hours; the self-test data is generated according to the total working time and the working intensity, for example, when the total working time is 8 hours, one-third of the work task is completed, and the working time reaches 2 hours, the self-test data is generated.

[0058] With such a setting, the operating time of the tin-plating equipment can be mastered in real time, and the opening of the self-check mode of the tin-plating equipment can be determined by the changes in the working intensity of the tin-plating equipment. The potential failure risks of the tin-plating equipment can be discovered in advance, and the failure prevention and maintenance of the tin-plating equipment can be improved. The status of the tin-plating equipment can be accurately monitored, and the failure of the tin-plating equipment during the tin-plating process can be adjusted in time, thereby reducing downtime and improving the tinning efficiency of the tin-plating equipment.

[0059] In one possible implementation, see Figure 3 , S240, generating self-inspection data according to the working time data, including:

[0060] S241, obtaining tinning completion data and target working time; wherein, the tinning completion data is used to indicate the total number of copper wires that have been tinned by the current tinning equipment, and the target working time is used to indicate the longest working time of the tinning equipment.

[0061] It can be understood that the longest working time of the tin-plating equipment indicated by the target working time is the longest time or the limit time that the tin-plating equipment can run.

[0062] Exemplarily, the tinning completion data can be obtained through a counting sensor; wherein the counting sensor can be installed at the finished product output end of the tinning equipment, such as a photoelectric sensor or an inductive sensor. When the tinned copper wire passes through the sensor, the sensor generates a pulse signal, and by counting these pulse signals, the number of tinned copper wires can be obtained. For example, for a photoelectric sensor, when the copper wire blocks the light, the sensor outputs a level change signal, and the counter increases by 1 after receiving the signal. The target working time can be determined by actual production testing, and can also be obtained by consulting the user manual of the tinning equipment or consulting the equipment manufacturer.

[0063] S242, if the working time of the tinning equipment indicated by the working time data reaches the target working time, the total number of copper wires that have been tinned indicated by the tinning completion data does not reach the target tinning number of the tinning equipment, or the working time of the tinning equipment indicated by the working time data does not reach the target working time, and the total number of copper wires that have been tinned indicated by the tinning completion data reaches the target tinning number of the tinning equipment, obtain strength information; wherein the strength information is used to reflect the remaining effective working capacity of the tinning equipment.

[0064] For example, if the working time of the tinning equipment indicated by the working time data reaches the target working time, and the total number of copper wires that have been tinned indicated by the tinning completion data does not reach the target tinning number of the tinning equipment, the strength information is obtained; if the working time of the tinning equipment indicated by the working time data does not reach the target working time, and the total number of copper wires that have been tinned indicated by the tinning completion data reaches the target tinning number of the tinning equipment, the strength information is obtained. The formula is: That is: target working time T target , the scheduled working time of the tinning equipment in one working cycle, the actual working time T actual , actual operating time, target tinning quantity N target , the total number of copper wires that the tinning equipment is expected to complete within the target working time, and the number of completed tinning N actual , the total amount of copper wire tinning actually completed, usually provided by the tinning completion data; It indicates the ratio of actual working time to target working time, reflecting the utilization of equipment working time; It indicates the difference between the actual tinning quantity completed and the target tinning quantity, reflecting the insufficient tinning efficiency of the equipment; α is a weight coefficient, which adjusts the working time and the tinning quantity, α (0≤α≤1), if the working time weight is large, then α is higher, the working time weight is 50%, then α is 0.5, the working time weight is 80%, then α is 0.8. Strength information I strengthThe range is between 0 and 1, where 1 means that the device has not consumed all its working capacity, and 0 means that the device has completely consumed its working capacity.

[0065] In a possible implementation, the method further includes:

[0066] S242A, if the working time of the tinning equipment indicated by the working time data reaches the target working time, and the total number of copper wires that have completed tinning indicated by the tinning completion data reaches the target tinning number of the tinning equipment, determine the self-test data.

[0067] For example, if the working time of the tinning equipment indicated by the working time data reaches the target working time, and the total number of copper wires that have completed tinning indicated by the tinning completion data reaches the target tinning number of the tinning equipment, the self-test data is determined, that is, According to I strength The value determines the self-test data.

[0068] S242B, if the working time of the tinning equipment indicated by the working time data does not reach the target working time, and the total number of copper wires that have completed tinning indicated by the tinning completion data does not reach the target tinning number of the tinning equipment, obtain the continue data; wherein the continue data is used to instruct the tinning equipment to continue tinning the copper wire.

[0069] For example, if the working time of the tinning equipment indicated by the working time data does not reach the target working time, and the total number of copper wires that have completed tinning indicated by the tinning completion data does not reach the target tinning number of the tinning equipment, no self-test data is generated, the tinning equipment is not subject to any control, and the tinning work continues.

[0070] S243, determining self-test data according to the strength information.

[0071] Exemplarily, the available time value of the tinning equipment is obtained according to the working time data indicating that the working time of the tinning equipment reaches the target working time, and the available tinning value is obtained according to the tinning completion data indicating that the total number of copper wires that have completed tinning does not reach the target tinning number of the tinning equipment, and the available tinning value and the available time value are determined as strength information.

[0072] With this setting, the working status of the tin-plating equipment can be accurately determined, and the equipment's work tasks can be better arranged according to the strength information. If the remaining effective working capacity of the tin-plating equipment is high, the production tasks can be appropriately increased, and the strength information can be reasonably used to optimize the production process and improve overall production efficiency.

[0073] In one possible implementation, see Figure 4 , S243, determining self-test data according to the strength information, including:

[0074] S2431, performing a first calculation on the tin-plating equipment based on the strength information to obtain first calculation data; wherein the first calculation data is used to indicate the working fatigue value of the tin-plating equipment.

[0075] It can be understood that the working fatigue value of the tin-plating equipment is calculated based on the strength information to obtain the first calculation data.

[0076] Exemplarily, the working fatigue value calculation formula is: That is, the work fatigue value is F, and the target working time is T target , the actual working time is T actual , the work fatigue value F is determined as the first calculation data.

[0077] S2432, performing a second calculation on the tin-plating equipment based on the strength information to obtain second calculation data; wherein the second calculation data is used to indicate a performance degradation value of the tin-plating equipment.

[0078] It can be understood that the second calculation is performed on the performance degradation of the tin-plating equipment based on the strength information to obtain the second calculation data. The performance degradation value of the tin-plating equipment indicated by the second calculation data is the performance degradation rate of the tin-plating equipment.

[0079] Exemplarily, the formula for the performance degradation ratio P is, That is, the performance degradation ratio is P, and the target tinning quantity is Q target , the actual tinning quantity is Q actual That is, the performance degradation ratio is P, which is determined as the second calculation data. For example, the target tinning quantity is Q target The actual number of tinned wires is Q. actual is 800, then 00 = 20%, which means that the performance of the tinning equipment has dropped by 20% relative to the target level.

[0080] S2433, calculating the tin-plating equipment according to the first calculation data and the second calculation data to obtain scoring data; wherein the scoring data is used to indicate the scoring value of the tin-plating equipment.

[0081] It can be understood that the tinning equipment is scored according to the working fatigue value F and the performance degradation rate P to obtain the scoring data. The formula of the equipment health score H is: H = α × F + (1-α) × P. α is a weight coefficient, which can be adjusted according to the actual needs of the tinning equipment and is not specifically limited here.

[0082] S2434, determining self-inspection data based on the score value of the tin-plating equipment indicated by the score data.

[0083] Exemplarily, according to the formula H=α×F+(1-α)×P, the score value of the tin-plating equipment is calculated, and the score value of the tin-plating equipment is compared with the preset score value. If the comparison result is less than the preset score value, a self-test instruction is obtained, and the self-test instruction is determined as the self-test data; wherein, the preset score value can be obtained by testing the working ability of the tin-plating equipment, and the preset score value can also be obtained by consulting the manufacturing manual. For example, according to the formula H=α×F+(1-α)×P, the score value of the tin-plating equipment calculated is 80, and the preset score value is 85. Then, the calculated score value of the tin-plating equipment is compared with the preset score value, that is, 80 is less than 75, so a self-test instruction can be obtained, and the self-test instruction is determined as the self-test data.

[0084] Such a setting helps to understand the loss of equipment in terms of the running time and manufacturing quantity of the tinning equipment, reflect the decline in the actual performance of the equipment, and achieve an overall assessment of the status of the tinning equipment. Based on the comprehensive assessment of the status of the tinning equipment, excessive or insufficient maintenance can be avoided, unnecessary equipment downtime can be reduced, and equipment problems can be accurately identified to arrange production tasks more reasonably and improve product quality stability.

[0085] S300, receiving the execution instruction of the self-test mode indicated by the self-test data, the tin-plating equipment performs automatic detection to obtain the detection data; wherein the detection data is used to indicate the sub-component with tin-plating defects obtained after the tin-plating equipment is detected.

[0086] It can be understood that after receiving the execution instruction of the self-test mode indicated by the self-test data through the serial communication, the tinning equipment automatically detects to obtain the sub-components with tinning defects; wherein, the serial communication reception is to wirelessly connect the tinning equipment with the control computer or controller through the serial port interface such as RS-232, RS-485, send instructions through the control end, and transmit them bit by bit in a specific data format (such as ASCII code or binary data). For example, the "START" instruction is sent to start the tinning operation, and the serial port controller at the receiving end (tinning equipment) receives the instruction and the tinning equipment starts and starts working.

[0087] In one possible implementation, see Figure 5 , S300, receiving the execution instruction of the self-test mode indicated by the self-test data, the tinning equipment performs automatic detection, and obtains the detection data, including:

[0088] S310, after receiving the execution instruction of the self-test mode indicated by the self-test data, obtaining the tinning status data of the tinned copper wire; wherein the tinning status data is used to reflect the tinning status of the current copper wire after tinning by the tinning equipment.

[0089] It can be understood that after receiving the execution instruction of the self-test mode indicated by the self-test data, the tinning status data of the tinned copper wire is obtained by the stylus method or the optical profilometry method; wherein, the stylus method can use a stylus surface roughness meter, which moves on the surface of the tinned copper wire and measures the microscopic undulations of the surface according to the vertical displacement of the stylus, thereby obtaining the surface roughness value. When the stylus passes through the surface of the tin-plated layer, the up and down displacement of the stylus will be recorded by the sensor and converted into an electrical signal to obtain roughness data; the optical profilometry method measures the surface of the tin-plated layer by analyzing the interference fringes of the light reflected from the surface of the tin-plated layer to obtain the surface roughness.

[0090] S320, performing corresponding analysis on the tin-plating equipment according to the self-test mode indicated by the self-test data to obtain tin-plating defect data; wherein the tin-plating defect data is used to indicate the type of tin-plating defects that occur in the tin-plating equipment during tin-plating.

[0091] Exemplarily, the tinning equipment is defectively analyzed according to the self-test mode indicated by the self-test data to obtain tinning defect data; wherein, the defect analysis includes component content detection, electrode performance detection and mechanical component detection; component content detection analyzes the content of the main salt (such as stannous sulfate), acid (such as sulfuric acid), and additives (such as brighteners, leveling agents, etc.) in the plating solution, and then determines whether the various components are within the normal process range. For example, if the concentration of stannous sulfate is too low, the tinning speed will slow down and the thickness of the coating will be insufficient; while too high a concentration may cause the coating to be rough and coarse, and detect the impurity content in the plating solution, such as copper ions (dissolved from copper alloy wires) and iron ions. Impurities may affect the quality of the tinning layer, resulting in uneven color of the coating, pinholes or reduced bonding strength of the tinning layer. Electrode performance detection is to check whether there is passivation on the anode surface. Anode passivation will hinder the normal dissolution of tin ions, resulting in a decrease in the concentration of tin ions in the plating solution, affecting the tinning speed and coating quality; check whether the hook or fixture of the cathode has poor contact. Poor contact will increase local resistance, affect the flow of current, and make the quality of the tinning layer at the corresponding position worse, which may cause defects such as partial lack of tinning or thin coating. The inspection of mechanical parts can be to check the working condition of the stirring system or circulation system of the tinning tank. Insufficient stirring or circulation will lead to local unevenness of the composition and temperature of the plating solution, affecting the uniformity and quality of tinning and causing coating defects.

[0092] In one possible implementation, see Figure 6 , S320, performing corresponding analysis on the tinning equipment according to the self-test mode indicated by the self-test data to obtain tinning defect data, including:

[0093] S321, performing self-detection of current density and tin deposition rate based on the self-detection mode indicated by the self-detection data to obtain detection matching data; wherein the detection matching data is used to reflect the matching status of the current density and tin deposition rate of the copper wire.

[0094] Exemplarily, a self-test of current density is performed according to a self-test mode indicated by self-test data to obtain a density value, and then a self-test of deposition rate is performed according to a self-test mode indicated by the self-test data to obtain a deposition rate, and the density value and the deposition rate are matched to obtain detection matching data.

[0095] In one possible implementation, see Figure 7 , S321, performing self-detection of current density and tin deposition rate based on the self-detection mode indicated by the self-detection data, and obtaining detection matching data, including:

[0096] S3211, based on the self-test mode indicated by the self-test data, obtaining the current density when the tinning equipment is tinning the copper wire; wherein the current density refers to the intensity of the current passing through the unit area of ​​the copper wire.

[0097] It can be understood that according to the self-test mode indicated by the self-test data, the current density is obtained according to the Hall effect current sensor method when the tinning equipment is tinning the copper wire; the Hall effect current sensor method uses the Hall effect. When the current passes through the copper wire conductor, a magnetic field is generated. The Hall effect current sensor can convert the magnitude of the magnetic field into a voltage signal V. The Hall effect current sensor is installed on the wire of the tinning equipment to sense the magnetic field generated by the current passing through the wire and convert it into a voltage signal proportional to the current. Through the proportionality coefficient K, the current can be calculated using the formula I = KV, and then according to the effective area A, the formula Calculate the current density J.

[0098] S3212, obtaining a tin deposition rate when the tinning equipment tin-plates the copper wire based on the self-test mode indicated by the self-test data; wherein the deposition rate refers to the speed at which metal ions are deposited from the solution onto the surface of the copper wire.

[0099] For example, when the tinning equipment is tinning the copper wire based on the self-test mode indicated by the self-test data, the tin deposition rate is calculated by using the Faraday's law calculation method; wherein the Faraday's law calculation method is based on the Faraday's law Where m is the mass of the deposited metal, M is the molar mass of the deposited metal, I is the current intensity, T is the tinning time, n is the number of electrons transferred in the reaction, and F is the Faraday constant; the molar mass m of the tin deposited within a certain time t can be calculated first, and for the tinning reaction Sn 2+ +2e - →S n, n=2, m is the molar mass of tin, M=118.71 g / mol, F=96485 C / mol; deposition rate v=m / t, convert the unit of mass m to mg, the unit of time t is s, then the unit of deposition rate v is mg / s.

[0100] S3213, matching the current density and the deposition rate of tin to obtain product data; wherein the product data is used to reflect the crystallization of the tin-plated layer.

[0101] It can be understood that according to Faraday's law get At the same time, the current density Substituting I = JA into the deposition rate formula, we can get It can be further known that the deposition rate v is linearly related to the current density J. When A, M, n and F are constants, the two are directly proportional. It can be further known that when the current density is low, the deposition rate is slow, and the crystals have enough time to grow, which may form larger and more uniform crystals. At a lower deposition rate, the tin ions have enough time to find a suitable position on the cathode surface to deposit, forming a more regular crystal structure; when the current density is high, the deposition rate is accelerated, which may lead to small and uneven crystals, because a large number of tin ions are deposited quickly, and the crystal growth has no time to arrange in an orderly manner, which may form irregular and small crystals. Therefore, according to whether the obtained current density value and deposition rate value are lower than the preset value, if the obtained current density value and deposition rate value are both lower than the preset value, then the crystallization condition is good, and the crystallization condition is determined as the product data; among them, a low matching result corresponds to a better crystallization condition of the tin plating layer, otherwise, the crystallization condition is poor.

[0102] S3214, obtaining detection matching data according to the crystallization condition of the tin-plated layer reflected by the product data.

[0103] Exemplarily, according to the description of step S3123 above, when the crystallization condition of the tin-plated layer reflected by the product data is good, it proves that the matching result is low, that is, the current density is low and the deposition rate is slow, resulting in a good match between the current density and the tin deposition rate. Conversely, when the current density is high, the deposition rate is fast and the crystallization condition is poor, resulting in a poor match between the current density and the tin deposition rate.

[0104] S322, performing electrode characteristic self-detection based on the self-detection mode indicated by the self-detection data to obtain polarity characteristic data; wherein the polarity characteristic data is used to reflect the dissolution condition of the anode and the current distribution condition of the cathode.

[0105] For example, according to Faraday's law The mass dissolved at the anode is proportional to the amount of electricity passed through. By measuring the mass difference of the anode before and after tinning, the amount of dissolution can be calculated. According to the Biot-Savart law (dB is the magnetic field element generated by the current element Idl at a distance r, μ 0 is the magnetic permeability of vacuum). Electric current will generate a magnetic field. By measuring the magnetic field strength at different positions around the cathode, the distribution of current can be obtained.

[0106] In one possible implementation, see Figure 8 , S322, performing electrode characteristic self-detection based on the self-detection mode indicated by the self-detection data to obtain polarity characteristic data, including:

[0107] S3221, obtaining the shape of the anode based on the self-test mode indicated by the self-test data, and obtaining dissolution data according to the shape of the anode; wherein the dissolution data is used to indicate the dissolution rate obtained according to the current shape of the anode, and the shape of the anode is the shape of the tin plate on the tin plating equipment during the tin plating process.

[0108] Exemplarily, based on the self-test mode indicated by the self-test data, the shape of the anode is obtained by using an image recognition method, and then the dissolution data is obtained according to the shape of the anode and the surface profile change method; the image recognition method is to use the monitoring camera on the tinning equipment to collect images of the anode, and then obtain the shape of the anode through image recognition. According to the shape of the anode and the surface profile change method, the contour of the anode surface can be measured regularly, and the contour changes at different time points can be compared. The surface of the anode is measured by using a surface profiler to obtain initial surface contour information, and the contour of the anode surface is measured regularly according to the time node of the self-test data, and the contour data at different time points are compared. For example, for a plane anode, the dissolution can be analyzed according to the height drop value at different positions on the surface; for a curved anode, the dissolution rate obtained according to the current anode shape can be obtained according to the curvature change and thickness change.

[0109] S3222, obtaining the shape of the cathode and the placement position of the cathode based on the self-test mode indicated by the self-test data; wherein the shape of the cathode is the shape of the copper wire during the tinning process, and the placement position of the cathode is the position where the copper wire is placed during the tinning process.

[0110] Exemplarily, based on the self-test mode indicated by the self-test data, the shape of the cathode is obtained by a three-dimensional scanning method and the placement position of the cathode is determined by a machine vision positioning method. The three-dimensional scanning method can use three-dimensional laser scanning or structured light scanning technology to perform three-dimensional scanning on the tinned copper wire to obtain the precise shape of the cathode. The machine vision positioning method can be to automatically identify the position of the tinned copper wire by installing a camera and a machine vision algorithm on the tinning equipment, that is, installing a camera at a key position of the tinning equipment, performing image denoising, enhancement, and binarization operations on the captured image, and using an image recognition algorithm to identify the contour and key feature points of the tinned copper wire. According to the intrinsic parameters (focal length, optical center, etc.) and extrinsic parameters (position and posture of the camera) of the camera, the physical coordinates are obtained, thereby determining the position of the tinned copper wire in the tinning tank.

[0111] S3223, obtaining change data according to the placement position of the cathode and the shape of the cathode; wherein the change data is used to indicate the position influence rate of the placement position of the cathode and the diameter change rate of the shape of the cathode.

[0112] Exemplarily, the position influence rate is calculated according to the placement position of the cathode and the diameter change rate is calculated according to the shape of the cathode to obtain the change data; wherein the position influence rate is calculated by the position influence rate formula When the tinned copper wire is placed in the standard position, the thickness of the tinned layer is h 0 When it is placed in other positions, the thickness of the tinned layer is h i ; The diameter change rate is: In which, it is assumed that the average diameter of the tinned copper wire is d i , the diameter measured at a certain position is d 0 , and then according to the position influence rate formula Calculated location impact rate and based on The calculated diameter change rate is determined as change data.

[0113] S3224, obtaining polarity characteristic data based on the dissolution data and the change data.

[0114] It can be understood that the dissolution rate indicated by the dissolution data and the shape of the tin plate on the tin-plating equipment as well as the position influence rate and diameter change rate indicated by the change data are directly determined as polarity characteristic data.

[0115] S323, obtaining tin plating defect data according to the detection matching data and the polarity characteristic data.

[0116] Exemplarily, the detection matching data and the polarity characteristic data are weighted to obtain a weighted result, and the weighted result is determined as the tin plating defect data; wherein, the detection matching data and the polarity characteristic data are weighted, and the detection matching data and the polarity characteristic data are allocated with a weight of 45% and a weight of 55%, and when the matching condition indicated by the detection matching data is good, the defects obtained by the dissolution condition of the anode and the current distribution condition of the cathode indicated by the polarity characteristic data are determined as the tin plating defect data; when the matching condition indicated by the detection matching data is poor, the current density and the deposition rate of tin indicated by the detection matching data, and the dissolution condition of the anode and the current distribution condition of the cathode indicated by the polarity characteristic data are determined as the tin plating defect data.

[0117] S330, obtaining detection data according to the tinning status data and the tinning defect data.

[0118] Exemplarily, the tinning condition of the copper wire after tinning indicated by the tinning status data and the tinning defect data are used to indicate the type of tinning defects that occur in the tinning equipment during tinning and are determined as detection data; wherein, the tinning condition of the copper wire after tinning is a quality difference value obtained by comparing the tinning quality value with a preset quality value; the tinning quality value and the preset quality value can be obtained by comparing the thickness, uniformity, surface roughness and glossiness of the tin plating layer.

[0119] With this setting, by obtaining the tinning status data, we can accurately understand the actual situation of the tinning equipment after tinning the copper wire, such as the thickness, uniformity, surface roughness, glossiness, etc. of the tinning layer, which helps to avoid serious damage to the equipment caused by long-term operation in a bad state. Through the feedback of the detection data, repairs or adjustments can be made when there are minor problems with the equipment, preventing small problems from turning into major failures, extending the service life of the tinning equipment, and reducing the downtime of the tinning equipment.

[0120] S400, adjusting the tinning parameters corresponding to the sub-components with tinning defects indicated by the detection data, and controlling the tinning equipment to tin the copper wire using the adjusted tinning parameters.

[0121] Illustratively, the tin-plating equipment is self-inspected through its self-inspection mode to obtain sub-components with tin-plating defects, the tin-plating defects of the sub-components are analyzed and the tin-plating parameters on the tin-plating equipment are adjusted, and then the copper wire is continued to be tinned using the adjusted tin-plating parameters; wherein, the tin-plating defects include long operating time of parts of the tin-plating equipment, lack of tin-plating liquid, high temperature of the tin-plating liquid, or increase or decrease of individual parameters due to long working time or work intensity.

[0122] In summary, according to this method, the problems of tinning equipment can be discovered in real time and in time, the situation where small problems of tinning equipment gradually accumulate into major failures can be reduced, and the situation where tinning equipment relies too much on manual inspection can be reduced, so as to control the quality of tinning within a stable range, make each batch of tinned copper wire meet the quality standards as much as possible, reduce the defective rate and shorten the adjustment time, make the inspection more accurate and efficient, greatly reduce the failure or shutdown of tinning equipment, and improve production efficiency.
