Technical Field

[0001] This invention belongs to the field of aluminum foil rolling technology, specifically an automatic control system for rolling ultra-thin aluminum foil for capacitors. Background Technology

[0002] Power capacitors are used in power systems and electrical equipment. Any two metal conductors separated by an insulating medium constitute a capacitor. Power capacitors contain aluminum foil, and the quality of the aluminum foil is closely related to the performance of the capacitor.

[0003] A patent application with publication number 201820188031 discloses an ultra-thin aluminum foil rolling device for high-capacity power capacitors, including a support frame, a drive roller, a driven roller, a cleaning block, and a control panel. The driven roller is arranged below the drive roller. A distance sensor and a tilt angle sensor are arranged inside the drive roller. A sensing block and the tilt angle sensor are arranged inside the driven roller. Rotating shafts are arranged at both ends of the drive roller and the driven roller. A support frame is arranged on the side of the rotating shaft away from the drive roller. An electric current is arranged at the other end of the rotating shaft on the side of the drive roller.

[0004] During the production of aluminum foil, different processing equipment with different processing performance is required for different aluminum foil thickness requirements. However, current processing equipment is generally complex in structure, has poor processing performance for thin aluminum foil, low production efficiency, and cannot guarantee product quality.

[0005] Therefore, the present invention provides an automatic control system for rolling ultra-thin aluminum foil for capacitors. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an automatic control system for rolling ultra-thin aluminum foil for capacitors, comprising a data acquisition module, a screening module, a transmission module, a rolling processing module, a data storage module, and a rolling analysis module;

[0008] The data acquisition module is used to collect and analyze aluminum foil quality information and rolling equipment information. The aluminum foil quality information includes the foil's thickness, weight, area, degree of damage, surface tension, and surface flatness. The specific steps for acquiring aluminum foil quality information are as follows:

[0009] Step 1: Measure the thickness, length, and width of the aluminum foil. Mark the thickness of the aluminum foil as Ai. Obtain the volume of the aluminum foil and calculate its weight. Mark the weight of the aluminum foil as Bi.

[0010] Step 2: Obtain the degree of damage to the aluminum foil and mark the degree of damage as Di. The specific process for obtaining the degree of damage to the aluminum foil is as follows: First, collect an image of the aluminum foil surface, set up a pixel grid for the damaged area of ​​the aluminum foil surface and color the damaged area of ​​the aluminum foil surface. Mark the fully colored pixel grid as the first type pixel grid and the incompletely colored pixel grid as the second type pixel grid. Count the number of first type pixel grids and multiply it by the area of ​​a single pixel grid to obtain the area of ​​all first type pixel grids. Mark the area of ​​all first type pixel grids as Di 1.

[0011] A two-dimensional coordinate system is established for each type of pixel grid. Based on the colored area of ​​each type of pixel grid, all edge points of the colored area are marked, and all edge points are connected by a curve to form a curve intersecting the coordinate axis. Two intersection points are obtained based on the intersection of the curve and the coordinate axis, and these two intersection points are marked as E1 and E2. Based on the position coordinates of intersection points E1 and E2 in the coordinate system, the definite integral formula is applied... Obtain the colored area within each second-type pixel cell, where a and b are the coordinates of intersection points E1 and E2. Sum the colored areas within each second-type pixel cell to obtain the colored areas within all second-type pixel cells. Mark all colored areas within the second-type pixel cells as Di2.

[0012] The area of ​​the damaged region on the aluminum foil surface (Di1+Di2) is obtained by summing the area of ​​all first-type pixel grids Di1 and the area of ​​the colored area within all second-type pixel grids Di2. The area of ​​the damaged region is marked as Di3. The area of ​​the aluminum foil is calculated based on the length and width of the aluminum foil and marked as Ci. The degree of damage to the aluminum foil is obtained by the ratio of the area of ​​the damaged region Di3 to the area Ci of the aluminum foil.

[0013] Step 3: Measure the surface tension of the aluminum foil using a tension meter and mark the surface tension of the aluminum foil as Gi;

[0014] Step 4: Count the number of high and low points on the aluminum foil surface, measure the horizontal height of the high and low points on the aluminum foil surface, calculate the difference in horizontal height between all high and low points and sum them up, and mark the result as H. Obtain the surface flatness of the aluminum foil by H / (sum of all high and low points - 1), and mark the surface flatness of the aluminum foil as Hi.

[0015] The rolling equipment information includes the rolling pressure of the rolling mill, the rolling speed of the rolling mill, the area of ​​the aluminum foil rolling table, the rolling time, and the rolling quality;

[0016] The specific steps for obtaining information about rolling mill equipment are as follows:

[0017] Step 1: Obtain the average unit pressure of the rolling mill and the horizontal projected area of ​​the contact surface between the rolling mill and the aluminum foil. Calculate the product of the average unit pressure of the rolling mill and the horizontal projected area of ​​the contact surface between the rolling mill and the aluminum foil to obtain the rolling pressure of the rolling mill. Mark the rolling pressure of the rolling mill as pi.

[0018] Step 2: Obtain the rolling mill engine shaft speed Nd i and the number of rolling mill shafts Np i;

[0019] According to the formula Obtain the rolling speed ND of the rolling mill;

[0020] Step 3: Obtain the rolling time and rolling quality of the rolling mill, and mark the rolling time as vi; the rolling quality is obtained as follows: count the number of finished products rolled by the rolling mill within the cycle time and the number of defective products among the finished products, and subtract the number of finished products rolled and the number of defective products among the finished products to obtain the number of finished products that meet the quality standards. The rolling quality is the ratio of the number of finished products that meet the quality standards to the total number of finished products, and mark the rolling quality as hi;

[0021] The obtained rolling pressure pi, rolling speed ND, rolling time vi, and rolling quality hi are processed using the formula... Obtain the rolling mill rolling coefficient Yi, where δ and ρ are preset scaling factors;

[0022] The screening module is used to determine whether aluminum foil meets the rolling standards before rolling and to reject aluminum foil that does not meet the rolling standards.

[0023] The aluminum foil that meets the rolling standards has a standard threshold range for thickness, weight, damage level, surface tension, and surface flatness. The parameters of the aluminum foil to be screened will be compared with the standard threshold. If all parameters of the aluminum foil to be screened are within the standard threshold range, the next step will be performed.

[0024] If any parameter of the aluminum foil to be screened is outside the standard threshold range, the aluminum foil is considered non-compliant and is rejected.

[0025] The transmission module is used to analyze the screened aluminum foil and transmit it to the rolling processing module; the analysis process is as follows:

[0026] First, the thickness Ai, weight Bi, area Ci, damage degree Di, surface tension Gi, and surface smoothness Hi of the obtained aluminum foil are processed using the formula: Obtain aluminum foil rolling parameters Wi, where ε and θ are preset proportional coefficients;

[0027] The standard threshold range for the preset aluminum foil rolling parameters is Wi 1-Wi2;

[0028] If the aluminum foil rolling parameter Wi is within the standard threshold range of Wi 1-Wi2, a transmission signal is generated, and the transmission module executes the transmission command according to the transmission signal to transmit the aluminum foil to the rolling processing module.

[0029] If the aluminum foil rolling parameter Wi is not within the standard threshold range of Wi 1-Wi2 for the aluminum foil rolling coefficient, a pause transmission signal is generated, and the transmission module does not execute the transmission command based on the pause transmission signal.

[0030] The data storage module is used to store rolling information, including information such as aluminum foil with different rolling parameters corresponding to rolling mills with different rolling coefficients. Specifically, all rolling mills are arranged from high to low according to the rolling coefficient Yi, and the top 30% of rolling mills are marked as the first type of rolling mill.

[0031] The bottom 30% of rolling mills are designated as Type II rolling mills;

[0032] The remaining rolling mills are designated as type III rolling mills;

[0033] Aluminum foils within the standard threshold range of aluminum foil rolling parameters Wi 1-Wi2 are classified according to the appropriate rolling mill type. For example, the appropriate rolling parameters for aluminum foils for the first type of press are Wi 1-m, the appropriate rolling parameters for aluminum foils for the second type of press are mn, and the appropriate rolling parameters for aluminum foils for the third type of press are n-Wi2.

[0034] The rolling processing module is used to roll aluminum foil according to the rolling information stored in the data storage module. First, the parameters of the aluminum foil to be rolled are input. The rolling processing module finds the corresponding rolling mill type according to the aluminum foil parameters and sends the aluminum foil to the corresponding rolling mill for rolling.

[0035] The rolling analysis module is used to analyze shaped capacitors rolled from aluminum foil. The specific analysis process is as follows:

[0036] Step 1: Construct a two-dimensional coordinate system based on the most standard and well-formed capacitor, label each structural vertex of the capacitor in the coordinate system, and obtain the coordinates of each vertex of the capacitor.

[0037] Step 2: Obtain the coordinates of each structural vertex of the rolled capacitor in the coordinate system;

[0038] Step 3: Capacitors whose error distance between the vertices of each structure does not exceed 0.5cm from the most standard and perfectly formed capacitor are considered qualified products;

[0039] Step 4: Calculate the error distance between the coordinates of each structural vertex of the obtained rolled capacitor and the coordinates of each structural vertex of the standard intact capacitor, where the error distance is calculated using the absolute value.

[0040] If the error distance is >0.5, it indicates that the rolled capacitor is unqualified; it also indicates that the rolling mill is in abnormal operation and needs to be adjusted or repaired.

[0041] If the error distance is ≤0.5, it indicates that the rolled capacitor is qualified.

[0042] The beneficial effects of this invention are as follows:

[0043] 1. The automatic control system for rolling ultra-thin aluminum foil for capacitors described in this invention acquires the quality information of the ultra-thin aluminum foil through a data acquisition module, performs preliminary screening of the aluminum foil based on the quality information through a screening module, and performs secondary screening of the screened aluminum foil through a transmission module and transmits it to the rolling processing module for screening and analysis of the aluminum foil, which greatly improves the product forming rate and the quality of leveling, and reduces the degree of defects in the finished product.

[0044] 2. The automatic control system for rolling ultra-thin aluminum foil for capacitors described in this invention stores aluminum foil quality information and rolling equipment information collected by the data acquisition device through a data storage device, thereby realizing the technical function of automatic classification of aluminum foil and rolling mill in the aluminum foil rolling process.

[0045] 3.

Sum the colored areas within each second-type pixel cell to obtain the colored areas within all second-type pixel cells. Mark all colored areas within the second-type pixel cells as Di2.

[0054] The area of ​​the damaged region on the aluminum foil surface (Di1+Di2) is obtained by summing the area of ​​all first-type pixel grids Di1 and the area of ​​the colored area within all second-type pixel grids Di2. The area of ​​the damaged region is marked as Di3. The area of ​​the aluminum foil is calculated based on the length and width of the aluminum foil and marked as Ci.
