Winding device and method for capacitor film production

Abstract

The invention discloses a winding device and method for capacitor film production, and relates to the technical field of winding device, including a panel. The invention facilitates flattening of a film to prevent folding through the cooperation of a winding wheel and a pressure wheel, thereby realizing the ability of the film to be flatly rolled up. The cooperation of a detection head and an electric push rod facilitates the detection of the film rolling posture and adjustment of alignment. The angle detection module accurately captures the slight position change of the film during the winding process, and transmits data to a controller when it is detected that the film has a tendency to deviate. The controller controls the telescopic rod of the electric push rod to extend and retract to drive a connecting shaft. The change in the front and rear position of the connecting shaft drives the correction plate to rotate around the rotating shaft, thereby realizing accurate adjustment of the relative angle between the correction wheel and the pressure wheel, and effectively avoiding the deviation of the film caused by its own angle deflection.

Description

Technical Field

[0001] The present invention relates to the technical field of winding equipment, and in particular to a winding equipment and method for producing capacitor films. Background Art

[0002] Film capacitors are also called plastic film capacitors. They use plastic film as dielectric. Film capacitors use metal foil as electrodes. They overlap plastic films such as polyethylene, polypropylene, polystyrene or polycarbonate at both ends and are rolled into a cylindrical capacitor. Depending on the type of plastic film, they are called polyethylene capacitors (also called Mylar capacitors), polypropylene capacitors (also called PP capacitors), polystyrene capacitors (also called PS capacitors) and polycarbonate capacitors.

[0003] In the prior art, when the film is offset during film winding operation, manual adjustment of the offset film is required. Manual adjustment has large manual errors, and the rolled film may still be offset after the adjustment is completed. When the film is rolled, wrinkles may occur due to changes in the tension on the film surface, resulting in insufficient compression of the rolled film roll and affecting the quality of the film.

[0004] Therefore, the present invention improves the existing equipment in view of the above problems. Summary of the invention

Correction side plates are vertically installed on the left and right sides of the correction plate, and correction wheels are horizontally provided at the front and rear ends between the opposite surfaces of the correction side plates, and both ends of the correction wheel are rotatably connected to the correction side plates.

[0012] Preferably, a control component is also provided inside the controller, and the control component includes an angle detection module and a thickness detection module;

[0013] An angle detection module detects the deviation angle data of the film and analyzes the detected deviation angle data to analyze whether the film has angle deviation, and then adjusts the deviation film after determining that the film has angle deviation;

[0014] The thickness detection module detects the thickness data of the film and analyzes the detected thickness data to determine whether the film has wrinkles. After determining that wrinkles have occurred, the warning light is used to warn the staff to adjust the film wrinkles.

[0015] Preferably, the angle detection module performs the following steps to analyze the angle data:

[0016] Step 1: Detect the distance detection points at the four corners of the correction side plate. The detection points detect the distance data between the film on the correction side plate and the correction side plate. The detected distance data is recorded as , , and , the length data of the corrected side plate is L;

[0017] Step 2: Use the corrected side panel length, film edge and deviation distance to form a right triangle. , then calculate the deviation angle When the film is smoothly transferred at the middle position of the two correction side plates, a reference line is established with the edge of the film, and the angle sensor detects the angle data between the edge of the film and the reference line. The mean a and standard deviation b of the angle data detected at the same time are calculated. The fluctuation range of the angle data is set to [a-2b, a+2b] according to the standard deviation and the mean. The angle data that is not within the fluctuation range is judged as an abnormal value. After the abnormal value is removed, the mean of the remaining data is calculated, and the calculated mean is recorded as the detection deviation angle ;

[0018] Step 3: If , the film position deviation is determined, the winding operation is stopped, and the film adjustment operation is performed; the correction plate is angled under the rotation of the rotating shaft. If , then the rotation axis is controlled to rotate clockwise; if , the rotating shaft is controlled to rotate counterclockwise; otherwise, the film deviation angle data is re-detected.

[0019] Preferably, the thickness detection module performs the following steps to analyze the thickness data:

[0020] Step 1: Preset the film thickness data as , the film thickness data detected is , then the thickness change rate of the film , when the calculated thickness change rate at the corresponding time exceeds the preset thickness change threshold, it is determined that wrinkles appear at the film detection position;

[0021] Step 2: Preset the film surface tension data as , the film tension data detected is , then the rate of change of film tension , the fluctuation range of the tension change rate of the preset film surface is , when the calculated rate of change of the film surface tension is not within the preset fluctuation range, it is determined that wrinkles appear at the film detection position;

[0022] Step 3: Establish a parallel surface on the surface of the correction plate, randomly select several monitoring points on the parallel surface corresponding to the film position, and detect the flatness of the film surface; calculate the mean of the detected film height data, and calculate the mean of the difference between the detected film height data and the film height mean data, and then perform square root calculation on the mean, and the calculated value is recorded as the root mean square error RMS. When the calculated root mean square error is greater than the preset error threshold, it is determined that wrinkles appear at the film detection position;

[0023] Step 4: retrieve the historical change data of thickness, tension and root mean square error during the film winding process, sort these data according to the size of the data, and remove the outliers. After removing the outliers, take the maximum and minimum values ​​of the remaining data to establish the fluctuation range; normalize the thickness data, tension data and root mean square error data to obtain , and , preset the weight coefficient of thickness data, tension data and root mean square error data on film wrinkles , and , then the comprehensive influence on film wrinkles , when the preset impact threshold When the film is creased at the detection position, it is determined that wrinkles appear;

[0024] Step 5: After determining that wrinkles appear at the film detection position, the winding device stops the winding operation and issues a warning light to notify the staff to adjust the film wrinkles.

[0025] Preferably, the winding method of the winding device for capacitor film production comprises the following steps:

[0026] Step 1: One end of the film passes over the correction wheel and moves downward, passes between the U-shaped clamps installed at the detection head position, passes under the pressure wheel, and then sticks upward to the surface of the winding wheel to complete the preparation work of the winding operation; the motor starts to drive the winding wheel to rotate through the first belt, and the winding wheel drives the pressure wheel to rotate through the second belt to carry out the film winding work;

[0027] Step 2: While the winding work is in progress, the distance sensor on the correction side plate and the angle sensor on the correction plate monitor the angle change of the film, and transmit the monitoring data to the control component inside the controller. The control component analyzes and processes the transmitted distance data and angle data to determine whether the film has an angle deviation. If an angle deviation occurs, the size of the angle deviation is calculated and the calculated angle data is transmitted to the controller. The controller controls the electric push rod to change its length. The change in the length of the electric push rod causes the rotating sleeve connected to one end of the electric push rod to drive the connecting shaft to rotate the angle, so that the rotating shaft connected to the connecting shaft drives the correction plate to rotate synchronously, so that the angle of the correction wheel on the correction plate changes, and the relative angle between the correction wheel and the pressure wheel changes, so that the film that is offset on the winding wheel is reset;

[0028] Step three: The thickness detection module of the control component determines whether the film is wrinkled from three aspects: the change of film thickness, the change of film surface tension and the change of flatness. If it is determined that wrinkles are present at the film detection position, the controller controls the winding device to stop the winding operation, and issues a warning through the warning light to notify the staff to adjust the film wrinkles; if wrinkles are not detected at the film detection position in terms of the change of film thickness, the change of film surface tension and the change of flatness, a comprehensive analysis is performed on the three aspects of film thickness change, film surface tension change and flatness to estimate whether the film will be wrinkled, and if wrinkles are determined to be present at the film detection position, a warning operation is performed in advance.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. Through the cooperation of the winding wheel and the pressure wheel, the film can be flattened to prevent folding, and the film can be flattened. Through the cooperation of the detection head and the electric push rod, the film winding posture can be detected and the alignment can be adjusted to prevent the film roll from wrinkling. Finally, the problem that the film roll rolled out by the existing winding equipment often has wrinkles or deviations, resulting in insufficient compression of the film roll volume and affecting the film quality is solved;

[0031] 2. The angle detection module accurately captures the subtle position changes of the film during the winding process. When the film is detected to have a tendency to deviate, the data is transmitted to the controller. The controller controls the telescopic rod of the electric push rod to extend and retract to drive the connecting shaft. The change in the front and rear position of the connecting shaft drives the correction plate to rotate around the rotation axis, thereby achieving precise adjustment of the relative angle between the correction wheel and the pressure wheel, effectively avoiding the deviation of the film caused by its own angle deflection;

[0032] 3. The thickness detection module detects changes in the film thickness data, tension data and flatness. After determining that wrinkles appear at the film detection position, the winding operation of the winding equipment is stopped, and a warning light is used to notify the staff to adjust the film wrinkles. The film thickness, tension and flatness data are used to determine whether wrinkles will occur in the film, so as to prevent the wrinkled film from being insufficiently compressed after winding, thereby affecting the quality of the film.

The change in the length of the electric push rod (13) causes the rotating sleeve (14) connected to one end of the electric push rod (13) to drive the connecting shaft (15) to rotate at an angle, so that the rotating shaft (12) connected to the connecting shaft (15) drives the correction plate to rotate synchronously, so that the angle of the correction wheel (17) on the correction plate changes, and the relative angle between the correction wheel (17) and the pressure wheel (8) changes, so that the film that has deviated on the winding wheel (7) is reset; Step 3: The thickness detection module of the control component determines whether the film is wrinkled from three aspects: the change in film thickness, the change in film surface tension and the change in flatness. If it is determined that wrinkles appear at the film detection position, the controller (4) controls the winding device to stop the winding operation and issues a warning light to notify the staff to adjust the film wrinkles. If wrinkles are not detected at the film detection position from the three aspects of film thickness change, film surface tension change and flatness change, a comprehensive analysis is performed on the three aspects of film thickness change, film surface tension change and flatness change to estimate whether the film will wrinkle. If wrinkles are determined to appear at the film detection position, a warning operation is performed in advance.
