For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.
[0055] Please refer to Figure 1 , the first aspect of the present application provides a rubber quality detection method, comprising the following steps:
[0056] S1, obtaining a to-be-detected image of a to-be-detected area of the battery cell;
[0057] Among them, corresponding to the pasting position of the adhesive tape, the to-be-detected area of the battery cell can be the end of the battery cell.
[0058] S2, performing gray scale comparison on the to-be-detected image to obtain a rubber-coated overlapping area;
[0059] Please refer to Figure 2 , in the to-be-detected image, the part with darker gray scale is the rubber-coated overlapping area, so after the gray scale comparison of the to-be-detected image, the rubber-coated overlapping area in the to-be-detected image can be obtained.
[0060] S3, determining a first edge curve and a second edge curve of the rubber-coated overlapping area;
[0061] In application, the adhesive tape is generally a square strip, so the rubber-coated overlapping area is generally rectangular. In this embodiment, as Figure 2 indicated, the first edge curve and the second edge curve can be two straight lines on the left and right sides of the rubber-coated overlapping area.
[0062] S4, obtaining the actual width of the rubber-coated overlapping area according to the intersection of the first edge curve and the second edge curve with a preset straight line.
[0063] In the embodiment, the preset straight line can be a transverse straight line where the middle position of the adhesive tape height is located, and intersects with both the first edge curve and the second edge curve; or the preset straight line can be obtained by taking a plurality of transverse straight lines intersecting with both the first edge curve and the second edge curve, obtaining a plurality of width values, and taking an average value from the plurality of width values, and taking the straight line corresponding to the average value as the preset straight line, that is, the length of the intersection point of the preset straight line and the first edge curve and the second edge curve is the average value of the width of the rubber coating overlap area, and the actual width of the rubber coating overlap area is taken as the actual width of the rubber coating overlap area, and then the actual width of the rubber coating overlap area is obtained by obtaining the two intersection points.
[0064] S5, determining whether the actual width is within the tolerance range of the preset width.
[0065] Specifically, if the actual width is within the tolerance range of the preset width, it indicates that the current battery cell has a qualified rubber coating quality.
[0066] The rubber coating quality detection method provided by the scheme can provide a reference basis for whether the battery cell rubber coating quality is qualified by the width of the rubber coating overlap area, and the rubber coating quality can be quickly detected.
[0067] In a more specific embodiment, please refer to Figure 3 On the basis of the above embodiment, step S3 comprises:
[0068] S31, outputting a gray scale change curve of the rubber coating overlap area according to the gray scale contrast result of the image to be detected.
[0069] The gray scale contrast result of the image to be detected refers to the comparison after the gray scale analysis of the image, for example, the gray scale feature information in the image can be extracted by a gray scale analysis tool, and then a gray scale change curve is generated. The gray scale change curve can be a line gray scale distribution curve (line profile), an image line gray scale average (linear averages) R01 boundary gray scale curve, etc.
[0070] Taking the line gray scale distribution curve as an example, the line gray scale distribution curve analyzes and draws the pixel gray scale change along a certain line segment in the image. Its horizontal axis is the pixel position index on the line segment, and the vertical axis is the gray scale of each point. The line gray scale distribution curve can be used to detect the boundary of adjacent parts in the image, quantitatively represent the gray scale change, and detect whether there is a certain feature in the image. In the line gray scale curve, the wave crest and the wave trough represent the increase and decrease of the gray scale of a region in the image along the selected line segment, and the width and amplitude of the wave crest and the wave trough represent the size and brightness of the region in the image, respectively. For example, if the image contains a region with higher brightness, a wave crest will appear in the gray scale distribution curve drawn along the line segment passing through it, and the higher the brightness of the region relative to the background, the steeper the wave crest.
[0071] Taking the image line gray mean ROl boundary gray curve as an example, the four types of line gray means of the pixels in the entire image or the specified rectangular region can be calculated, including the linear average of the gray of each column of pixels along the X-axis direction, the linear average of the gray of each row of pixels along the Y-axis direction, the average of the gray of the pixels perpendicular to the diagonal line along the diagonal line from the lower left to the upper right, and the average of the gray of the pixels perpendicular to the diagonal line along the diagonal line from the upper left to the lower right.
[0072] S32, determining the edge points of the rubber-coated overlapping region according to the gray change curve;
[0073] S33, performing curve fitting on the edge points to obtain the first edge curve and the second edge curve of the rubber-coated overlapping region.
[0074] Specifically, the gray change curve is used to represent the degree of gray change on the to-be-detected image. Through the gray change curve, the edge points of the rubber-coated overlapping region can be better determined. Then, the first edge curve and the second edge curve are fitted through the edge points.
[0075] In another embodiment, referring to Figure 4 The step S1 in any of the above embodiments can specifically be: acquiring a plurality of to-be-detected images of the battery cell at a plurality of angles of the to-be-detected region of the battery cell.
[0076] In the process of photographing the battery cell, since the rubber-coated overlapping regions of different battery cells can be located at different angles when the battery cells are delivered, in the present embodiment, the circumferential surface of the battery cell can be detected by acquiring a plurality of to-be-detected images of the circumferential surface of the battery cell, thereby improving the accuracy of the rubber coating quality detection.
[0077] In other embodiments, referring to Figure 5 After the step S2 and before the step S3, the method further includes:
[0078] S20, judging whether the to-be-detected image is distorted, and if so, performing restoration processing on the to-be-detected image.
[0079] Specifically, when applied to a cylindrical battery cell, photographing the battery cell from the side of the battery cell can cause a distorted region in the image due to the curvature of the battery cell; therefore, if the to-be-detected image with the distorted region is directly subjected to gray comparison, the rubber-coated overlapping region obtained will also be distorted, resulting in inaccurate detection structure.
[0080] In the present embodiment, by performing restoration processing on the to-be-detected image with the distortion, the situation of directly detecting the distorted image can be avoided, thereby improving the accuracy of detection.
[0081] In a further improved embodiment, referring to Figure 6The step S20 includes a division step S21 and a judgment step S22.
[0082] The division step S21 includes dividing the image to be detected into a divided image including a first region and a second region.
[0083] The judgment step S22 includes comparing the divided image with a template image to determine whether the encapsulation overlap region is completely located in the first region, and if not, performing restoration processing on the divided image.
[0084] Specifically, the first region can be a verification region in which no distortion region exists, and the second region can be an image distortion region. In the judgment step S22, when it is determined that the encapsulation overlap region in the divided image is completely displaced in the first region, step S3 can be entered; when it is determined that the divided image is partially or entirely located in the second region, the encapsulation overlap region partially or entirely displays distortion on the image, and then the divided image is processed to restore the encapsulation overlap region to normal display on the image.
[0085] The template image is a preset image in which the encapsulation overlap region in a plurality of angles of the side surface of the battery cell is normally displayed. By comparing the divided image with the template image, it can be determined whether the encapsulation overlap region is located in the first region or the second region.
[0086] In an embodiment, the restoration processing includes synthesizing the divided image with other images to be detected so that the encapsulation overlap region in the synthesized divided image is completely located in the first region.
[0087] Specifically, after the divided image is synthesized with other images to be detected at different angles, a normal image in which the encapsulation overlap region is normally displayed on the image can be obtained, that is, the encapsulation overlap region is completely located in the first region, and then step S3 can be entered.
[0088] As a further improvement, please refer to Figure 7 The step S20 further includes a pre-judgment step S200.
[0089] The pre-judgment step S200 includes performing gray scale recognition on the image to be detected to determine whether the gray scale value of the image to be detected is within a preset gray scale value tolerance range, and if so, the division step S21 is entered.
[0090] Specifically, if the gray scale value of the image to be detected is within the preset gray scale value tolerance range, it indicates that the encapsulation overlap region exists in the image to be detected, and then the division step S21 is entered. If the gray scale value of the image to be detected is not within the preset gray scale value tolerance range, it indicates that the encapsulation overlap region does not exist in the image to be detected, and the image can be discarded.
[0091] In an embodiment, please refer to Figure 8 andFigure 9 After step S1, the following steps are further included:
[0092] S61, performing gray processing on the to-be-detected image to obtain a gray change curve of the to-be-detected image;
[0093] S62, obtaining a lower edge point of the adhesive tape according to the gray change curve;
[0094] S63, determining a height maximum value and a height minimum value of the adhesive tape according to a distance between the lower edge point and a preset reference line;
[0095] S64, judging whether the height maximum value and the height minimum value are both within a preset height standard range.
[0096] Specifically, step S61 can occur after step S1 or after step S5. If step S61 occurs after step S5, the gray change curve obtained in step S31 can be directly used.
[0097] In an embodiment, the preset reference line can be a line on which the heights of the battery cells lie, because the heights of the battery cells vary little and can be regarded as a straight line. The height of the battery cell can be calculated through the distance between the lower edge point and the preset reference line, and then the height maximum value and the height minimum value of the adhesive tape attached to the side surface of the battery cell are obtained. Then, the height maximum value and the height minimum value are compared with the preset height standard range. If both of them are within the preset height standard range, the adhesive tape is qualified.
[0098] As an implementation, the preset reference line can also be a fitting straight line of the upper edge of the adhesive tape. The height maximum value and the height minimum value of the adhesive tape can be determined by comparing the distance between the lower edge point and the fitting straight line of the upper edge of the adhesive tape.
[0099] The second aspect of the embodiment of the present application provides an adhesive quality detection device for implementing any of the above adhesive quality detection methods.
[0100] The device can include an image acquisition module, a comparison module, an analysis module and a judgment module.

[0104] The judgment module is configured to judge whether the actual width is within a tolerance range of the preset width, so as to detect whether the rubberizing quality is qualified.
[0105] In the above embodiments, the image acquisition module 1 can be a camera, and the plurality of image acquisition modules 1 are evenly distributed around the circumferential surface of the battery cell. Figure 10
