The present invention provides a precise production system of electrolytic copper foil and a precise production method of electrolytic copper foil, wherein the system includes a production executive mechanism and a production control module. During production, the target current efficiency value is obtained first, and then the target production specification is obtained, and according to the target production specification, based on the preset electrolysis model and the target current efficiency value, the initial electrolysis time and initial current intensity are obtained, and then according to the initial electrolysis time and the initial current intensity, a signal is sent to the production executive mechanism to control the production executive mechanism to start electrolysis, and finally the actual production specification is obtained, and according to the actual production specification and the target The production specification, based on the preset electrolysis model, obtains the corrected current intensity, and sends a signal to the production actuator according to the corrected current intensity, so as to control the production actuator to continue electrolysis. Compared with the prior art, the present invention does not use fixed parameters for production, but uses unfixed current, and adjusts to correct current intensity at any time during the production process, making production more flexible and more accurate.

In a preferred embodiment, the production execution mechanism further includes a motor, a reduction transmission mechanism, a cathode roller and an electrolytic cell, the motor is connected to the reduction transmission mechanism, the reduction transmission mechanism is connected to the cathode roller, and the peripheral surface of the cathode roller extends into the electrolytic cell. It can be understood that in the actual production actuators used for electrolytic copper foil, the parts other than the above-mentioned parts are all prior art, so this article does not give too much explanation.

In order to better implement the precise production system of electrolytic copper foil in the embodiment of the present invention, on the basis of the previous embodiment of the precise production system of electrolytic copper foil, correspondingly, as shown in FIG. 2 , the present invention also provides a precise production method of electrolytic copper foil, which is applied to the precise production system of electrolytic copper foil in the previous embodiment, including:

S201. Obtain a target current efficiency value;

S202. Obtain the target production specification, and obtain the initial electrolysis time and initial current intensity according to the target production specification, based on the preset electrolysis model and the target current efficiency value;

S203. Send a signal to the production actuator according to the initial electrolysis time and the initial current intensity, so as to control the production actuator to start electrolysis;

S204. Obtain the actual production specification, and obtain the corrected current intensity based on the preset electrolysis model according to the actual production specification and the target production specification, and send a signal to the production actuator according to the corrected current intensity, so as to control the production actuator to continue electrolysis.

In a preferred embodiment, the preset electrolysis model includes:

M=KITη

In the formula, M is the production specification, K is the electrochemical equivalent, I is the current intensity, T is the electrolysis time, and η is the current efficiency value. Among them, the production specification M is the weight of the electrolytic deposition layer, which is the specification model of the product, measured by the surface density of the product (gram weight per square centimeter), and is the final product of production and the final object of people's quality control. The electrochemical equivalent K refers to the amount of material precipitated when passing the same amount of electricity (generally 1C) in different electrolytes, such as the amount of electricity that 1g equivalent of any substance passes through 9560°C or 26.8A. In this embodiment, the electrochemical equivalent is 1.186g/A.h, which can also be determined according to specific conditions in practice. The current intensity I is measured by ampere (A), which is a production condition that can be adjusted and controlled in production, not the final control object. The electrolysis time T is the residence time of the continuously running electrode (cathode roll) in the electrolytic cell, which can be controlled by the linear speed of the cathode roll in this embodiment. The linear speed of the cathode roller is transmitted through the reduction mechanism by the rotation speed of the motor. Controlling the rotational speed of the motor means controlling the line speed of the cathode roller and indirectly controlling the electrolysis time. The current efficiency η is a percentage, which changes in real time with the operation of the equipment, and is the main source of interference. It should not be replaced by a fixed value at will, but should be accurately calculated and controlled.

The specific derivation process of the above preset electrolysis model is as follows:

Faraday's first law of electrolysis: The weight of the substance precipitated on the electrode is proportional to the current intensity and the passing time, that is, it is proportional to the passing electricity.

m=Kit=kQ

In the formula: m is the amount of precipitated (or dissolved) substances on the electrode/g; I is the passing current intensity/A; t is the passing time/h; Q is the passing electricity/(A.h); m is a proportional constant.

Faraday's second law of electrolysis: in different electrolytes, when the same amount of electricity is passed, the weight of the substance precipitated in multiple solutions is proportional to its chemical equivalent, and any substance that precipitates 1g equivalent must pass through the electricity of 96500C or 26.8A.h.

In the formula: m is the amount/g of the precipitated (or dissolved) substance on the electrode; Q is the electricity passed through/(A.h); n is the gram equivalent of the substance; F is the amount of electricity required for 1g of the substance precipitated (or dissolved) on the electrode during electrolysis.

In summary, the electrochemical equivalent K can be obtained from the above two formulas:

The above formula shows that the electrochemical equivalent of each substance is directly proportional to their atomic weight and inversely proportional to their valence. For variable valence elements, because different valence states have different equivalent values, their electrochemical equivalents are also different. Copper is monovalent in this embodiment.

Cu ⁺ +e = Cu

Therefore, the electrochemical equivalent of monovalent copper is 63.55/2/26.8=1.186g/A.h

Due to the existence of side reactions:

Zn ²⁺ +2e→Zn

2H ⁺ +2e→H ₂ ↑

Thus, there is an efficiency problem with the electricity fed to the electrolyzer. The mass of the actually precipitated substance is always different from the theoretically calculated weight. The ratio of the actual precipitated weight to the theoretically calculated weight is expressed as a percentage, which is called the current efficiency, and is often expressed by "η".

In the formula, m is the weight of the actual precipitated substance/g; I is the current/A; t is the time/h; k is the electrochemical equivalent/[g×(A×h) ^-1 ].

Based on the above series of formulas, the preset electrolysis model in this application can be obtained.

It can be understood that in practice, other models can also be selected as the preset electrolysis model according to specific situations.

In a preferred embodiment, the above step S201, obtaining the target current efficiency value, specifically includes:

Send a signal to the production executive body for trial production, and obtain the trial production product parameters and the actual mechanism state parameters of the production executive body;

Obtaining an initial current efficiency value according to the actual mechanism state parameters;

According to the trial production product parameters, the initial current efficiency value is corrected to obtain the target current efficiency value.

In the existing production process, a fixed current efficiency value is used for calculation to guide production. In actual work, the current efficiency is not a fixed value due to factors such as temperature, pressure, electrolyte concentration, chemical composition (such as chloride ion content, acid content, etc.), electrode and electrode spacing, and the material and shape of the electrolytic cell. The current efficiency of the same production equipment in different working conditions and different time periods is not a fixed value. Using a fixed current efficiency value introduces errors.

Therefore, in this embodiment, trial production is carried out before formal production, and product inspection is carried out. The correct current efficiency value (i.e. the initial current efficiency value) is obtained by using the test results (i.e. the trial production product parameters) in combination with the current intensity and the cathode roller speed during the trial production (i.e. the actual mechanism state parameters). Product inspection is carried out at the beginning and end of each batch, and the current efficiency value is corrected (that is, the target current efficiency value is obtained), forming a closed-loop quality control mode. The above process can be repeated, and accurate current efficiency values of different production equipment and different working conditions can be obtained, and product errors caused by inaccurate current efficiency values can be eliminated.

Further, in a preferred embodiment, in step S204, obtain the actual production specification, and obtain the corrected current intensity according to the actual production specification and the target production specification based on the preset electrolysis model, and send a signal to the production actuator according to the corrected current intensity to control the production actuator to continue electrolysis, specifically including:

Obtaining a first production deviation value according to the actual production specification and the target production specification;

Correcting the initial current intensity based on the preset electrolysis model according to the first production deviation value to obtain the corrected current intensity;

Sending a signal to the production actuator according to the modified current intensity, so as to control the production actuator to continue electrolysis.

By adjusting the current intensity through the above process, precise control in the production process can be realized, and the specific principle will be explained in detail later.

Further, as shown in FIG. 3 , in a preferred embodiment, before step S204, it also includes:

S205. Obtain the actual production specification, and obtain the corrected electrolysis time based on the preset electrolysis model according to the actual production specification and the target production specification, and send a signal to the production actuator according to the corrected electrolysis time, so as to control the production actuator to continue electrolysis.

Although adjusting the electrolysis time can also control the final specifications, its accuracy is far less than that of adjusting the current intensity. In this embodiment, the electrolysis time is first adjusted, and then the current intensity is adjusted to achieve the effect of rough adjustment first and then fine adjustment.

Specifically, in a preferred embodiment, the actual production specification is obtained above, and the corrected electrolysis time is obtained based on the actual production specification and the target production specification based on the preset electrolysis model, and a signal is sent to the production actuator according to the corrected electrolysis time to control the production actuator to continue electrolysis, including:

Obtaining a second production deviation value according to the actual production specification and the target production specification;

Correcting the initial electrolysis time based on the preset electrolysis model according to the second production deviation value to obtain the corrected electrolysis time;

Sending a signal to the production actuator according to the modified electrolysis time, so as to control the production actuator to continue electrolysis.

There are many specific means for adjusting the electrolysis time, which need to be determined according to the structure of the actual production actuator. Therefore, in combination with the specific structure of the production actuator in the previous embodiment, in a preferred embodiment, in the above steps, according to the corrected electrolysis time, a signal is sent to the production actuator to control the production actuator to continue electrolysis, specifically including:

Obtaining the specification parameters of the cathode roller of the cathode roller;

Obtain the target cathode roller rotation speed according to the specification parameters of the cathode roller and the corrected electrolysis time;

According to the target cathode roller rotation speed, a signal is sent to the production actuator to control the production actuator to continue electrolysis.

Further, in a preferred embodiment, according to the target cathode roller speed in the above process, a signal is sent to the production actuator to control the production actuator to continue electrolysis, specifically including:

Obtaining the motor specification parameters of the motor and the transmission specification parameters of the reduction transmission mechanism;

Obtaining a target motor speed according to the motor specification parameter, the transmission specification parameter and the target cathode roller speed;

According to the target motor speed, a signal is sent to the production actuator to control the production actuator to continue electrolysis.

The present invention also provides a more detailed embodiment to illustrate the above steps S204 and S205 more clearly:

In the production process of the present embodiment, the electrolysis time is the residence time of the continuously running electrode (cathode roll) in the electrolytic cell, which is controlled by the linear speed of the cathode roll rotation. The line speed is calculated by the motor speed, the reduction ratio of the reduction mechanism, the diameter of the cathode roller and the circumference ratio. Since pi is an irrational number, the calculated linear velocity is an approximate value. If this approximate value is directly used for control, it will cause product errors.

Therefore, in this embodiment, the rotation speed of the motor is directly controlled, the linear speed of the cathode roller is indirectly controlled, and the electrolysis time is finally controlled. The following results can be obtained through experiments:

In the equipment in this embodiment, the specification parameters of the cathode roller include: the diameter of the cathode roller is 2.016 meters, and the width of the cathode roller is 1.39 meters. The transmission specification parameters include: the reduction ratio of the reduction mechanism is 1045.3. The motor specification parameters include the upper and lower limits of the motor speed, etc. The electrochemical equivalent is 1.186, and the current efficiency is 97%.

1) To produce products with a gram weight of 855, the production current is 34000A, and the required line speed is approximately equal to 0.548 meters per minute.

Using different line speeds near the value range of 0.548, the grammage of the products produced is as follows:

Table 1 Comparison table of production results based on different line speeds

Production current (A) Linear speed(m/min) Gram weight(g/m ² ) 34000 0.54 868.5 34000 0.55 852.7 34000 0.56 837.5

2) To produce products with a gram weight of 855, the production current is 34000A, and the required motor speed is about 90.53RPM.

Using different motor speeds around the value range of 90.53, the weight of the products produced is as follows:

Table 2 Comparison table of production results based on different motor speeds

Production current (A) Motor speed (RPM) Gram weight(g/m ² ) 34000 90 860.1 34000 91 850.1 34000 92 841.4

Combining Table 1 and Table 2, it can be seen that when producing products with a grammage of 855, the production current is 34000A, and when the line speed is adjusted by 0.01m/min, (this resolution is the smallest unit that can be controlled in actual production), the grammage of the product obtained changes by 15.23 grams. When the motor speed is adjusted by 1rmp (this resolution is the smallest unit that can be controlled during actual production), the gram weight of the obtained product changes by 9.25 grams. For the production of products with the same specifications, different control concepts and methods will result in completely different control effects when controlling different process parameters. Converting the control line speed to control the motor speed can improve the control accuracy and eliminate the error caused by irrational numbers involved in the calculation.

Furthermore, in the existing production process, a fixed current intensity is adopted, and the electrolysis time is adjusted for production. It can be seen from the above results that there are errors in the product. Therefore, the present invention does not use a fixed current for production. The following results can be obtained through experiments:

Based on the same equipment, the diameter of the cathode roller is 2.016 meters, the width of the cathode roller is 1.39 meters, the reduction ratio of the reduction mechanism is 1045.3, the electrochemical equivalent is 1.186, and the current efficiency is 97%.

To produce products with a grammage of 855, the motor speed is 91RPM, and the required current is 34175.63A. Different current intensities are used around the value range of 34175.63. The grammage of the produced products is as follows:

Table 3 Comparison table of production results based on different current intensities

Motor speed (RPM) Current intensity (A) Gram weight(g/m ² ) 91 34175 854.98413 91 34176 855.00915 91 34177 855.03417

It can be seen from Table 3 that when the current intensity is adjusted by 1A, (this resolution is the smallest unit that can be controlled in actual production), the gram weight of the obtained product changes by 0.025 grams. Obviously, adjusting the current intensity is more accurate than controlling the electrolysis time. It can improve the control precision by 4 orders of magnitude. Can effectively eliminate product errors.

In the existing production process, the production specifications are first determined, and then the production is carried out with a fixed current intensity. According to the above, it can be seen that the product specification is fixed, and the current intensity is fixed, the electrolysis time will also be fixed, and the production speed will also be fixed. There is no flexibility in production, and the production speed cannot be adjusted in time according to production needs, and the error is extremely large.

Therefore, the present invention selects production specifications, does not use fixed current for production, adopts flexible production speed, and adjusts current intensity in real time. Such a method can adjust the production speed in real time during production, and the production is flexible, and the accuracy of adjustment during the production process can be guaranteed by adjusting the current intensity. Specifically, the core of the present invention to improve accuracy is mainly reflected in the following three aspects:

1. Change the control line speed to directly control the motor speed.

2. Under the condition of fixed current, the original production method of adjusting the line speed is changed to calculate and select the appropriate motor speed, and flexibly adjust the current intensity

3. The fixed current efficiency is changed to the accurate calculation of current efficiency, and real-time closed-loop adjustment.

The present invention provides a precise production system of electrolytic copper foil and a precise production method of electrolytic copper foil, wherein the system includes a production executive mechanism and a production control module. During production, the target current efficiency value is obtained first, and then the target production specification is obtained, and according to the target production specification, based on the preset electrolysis model and the target current efficiency value, the initial electrolysis time and initial current intensity are obtained, and then according to the initial electrolysis time and the initial current intensity, a signal is sent to the production executive mechanism to control the production executive mechanism to start electrolysis, and finally the actual production specification is obtained, and according to the actual production specification and the target The production specification, based on the preset electrolysis model, obtains the corrected current intensity, and sends a signal to the production actuator according to the corrected current intensity, so as to control the production actuator to continue electrolysis. Compared with the prior art, the present invention does not use fixed parameters for production, but uses unfixed current, and adjusts to correct current intensity at any time during the production process, making production more flexible and more accurate.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention shall be covered within the scope of protection of the present invention.
