[0026] In order to enable ordinary persons in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0028] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties.

[0029] The existing technology usually requires the ear detection to be performed according to the grayscale value of the image in a given ROI (Region Of Interest), but there is a problem of low detection efficiency. In addition, the detection effect in the existing technology is easily affected by lighting conditions. It has a certain effect under backlight conditions, but it is completely unable to detect the folding under light conditions due to the reflection of the ear.

[0030] Based on this, the present application embodiment provides a tab folding detection method, such as Figure 1 As shown, the method comprises the following steps:

[0031] Step S101: acquiring a captured image, wherein the captured image is obtained by photographing the pole piece and the pole lug under the irradiation of a laser generator;

[0032] In an embodiment of the present application, the laser generator can emit laser, thereby forming a laser pattern on the pole piece and the pole ear, and then the pole piece and the pole ear are photographed using a camera. After the captured image is formed, the captured image will not only include the image of the pole ear and the pole piece, but also the laser pattern.

[0033] Optionally, the laser pattern may be various graphics, such as lines, squares, rectangles, circles, etc.

[0034] Preferably, the laser generator can emit line laser, so as to form laser lines on the pole piece and the pole ear.

[0035] Preferably, the width of the laser line can be set to be less than or equal to 0.5 mm, so that the influence of the laser line on the data can be reduced as much as possible while the laser line can be seen clearly.

[0036] In practical applications, the laser generator and the camera can be fixed on a rigid body. By adjusting the positions of the camera and the laser generator, the pole piece and the pole lug can be clearly imaged in the camera, and the laser can be irradiated onto the pole piece and the pole lug.

[0037] Preferably, if Figure 2 As shown, the laser generator can be arranged directly above the pole piece and the pole lug, so that the laser can directly illuminate the pole piece and the pole lug, and the camera can be arranged on one side of the laser generator, so that the camera can photograph the pole lug and the pole piece at an angle from the side of the laser generator.

[0038] Preferably, an infrared filter may be provided in front of the lens of the camera, so that the laser light emitted by the laser generator can be better imaged in the camera.

[0039] Step S103: extracting the laser pattern in the captured image to obtain actual laser pattern parameters;

[0040] In the embodiment of the present application, during normal operation, each frame of image can be collected, and the laser pattern in each frame of image can be extracted to obtain the actual laser pattern parameters of each frame of image.

[0041] In an embodiment of the present application, the laser pattern may be extracted based on an existing edge extraction algorithm, which is not elaborated in the present application.

[0042] Step S105: determining whether the tab is folded according to the actual laser pattern parameters.

[0043] In an embodiment of the present application, it is possible to determine whether the pole ear is folded based only on the actual laser pattern parameters. For example, the laser pattern is a square frame surrounded by laser lines. If the pole ear is not folded, then the actual laser pattern parameters extracted should be a closed frame. If the actual laser pattern parameters are a non-closed frame, it can be determined that the pole ear is folded. It should be noted that when judging whether the laser pattern is a closed frame, the influence of the laser middle fault is not considered, that is, only whether the part outside the laser middle fault is continuous is considered. In practical applications, the lines of the laser pattern can also be thickened by a certain expansion coefficient to blur the laser middle fault part, and then judge whether the laser pattern is a closed frame.

[0044] Preferably, the actual laser pattern parameters can be compared with standard laser parameters, so as to more accurately determine whether the tab is folded.

[0045] That is, determining whether the tab is folded according to the actual laser pattern parameters (i.e., step S105) may include: obtaining preset standard laser parameters; determining whether the tab is folded according to the comparison result between the actual laser pattern parameters and the standard laser parameters.

[0046] In the embodiments of the present application, as Figure 3 shown, the standard laser parameters can be obtained by pre-collecting and calibrating a standard pole piece with the system composed of the camera and the laser generator. Taking the emitted laser as a line laser as an example, the calibration process may include the following steps:

[0047] (1) Extract the images of the line laser on the standard pole piece and the standard tab.

[0048] (2) Calculate the total length LA of the line laser (i.e., the standard laser line length, as Figure 4 shown).

[0049] (3) Calculate the maximum spacing value KA of the middle section of the line laser (i.e., the standard laser middle section spacing, as Figure 4 shown).

[0050] Among them, because the standard tab has no coating, while the standard pole piece has a coating (such as the coated area shown in Figure 4 ), so their heights are different, that is, a height difference is generated between the standard tab and the standard pole piece. As shown in Figure 4 shown, when the laser shines on it and the camera takes a picture at an angle from the side, a fault will occur in the middle of the line laser on the standard tab and the standard pole piece.

[0051] In the embodiments of the present application, the actual laser pattern parameters at least include one of the following: the maximum length of the actual laser line and the maximum spacing of the actual laser middle section, and the standard laser parameters at least include one of the following: the standard laser line length and the standard laser middle section spacing.

[0052] Correspondingly, in some embodiments, determining whether the tab is folded according to the comparison result between the actual laser pattern parameters and the standard laser parameters may include:

[0053] When the maximum length of the actual laser line is less than the first preset ratio of the standard laser line length, it is determined that the tab is folded.

[0054] For example, when the maximum length of the actual laser line is denoted as LB, if LB < LA * 0.8 (i.e., the first preset ratio is set to 0.8, and of course this first preset ratio can be adjusted, such as it can be set to 0.7, 0.85, etc.), it indicates that the tab has a folded situation.

[0055] In some other embodiments, determining whether the tab is folded according to the comparison result between the actual laser pattern parameter and the standard laser parameter may include:

[0056] When the actual maximum spacing of the laser intermediate faults is greater than a second preset ratio of the standard laser intermediate fault spacing, it is determined that the pole ear is folded.

[0057] For example, when the actual maximum spacing of the laser intermediate fault is recorded as KB, if KB>KA*1.5 (that is, the second preset ratio is set to 1.5, of course, the second preset ratio can be adjusted, such as being set to 1.4, 1.6, etc.), it indicates that the pole ear is folded.

[0058] In the embodiment of the present application, it is possible to determine whether the battery cell tab is in a folded state by analyzing the acquired data.

[0059] By testing the positive and negative tabs of the complete battery cell, the folded pole pieces can be effectively detected under different lighting conditions, and the efficiency is greatly improved.

[0060] Furthermore, in the embodiment of the present application, the coefficient can be flexibly changed by calibrating the standard pole piece, which is more universal compared to the prior art.

[0061] In practical applications, the method described in the embodiments of the present application can be applied to most equipment that requires tab detection in core making processes, including but not limited to stacking machines (cutting, stacking, thermal lamination, etc.) and winding machines (EV, cylindrical, welding, laser, etc.).

[0062] The present application also provides a tab folding detection device, such as Figure 5 As shown, the device may include:

[0063] An image acquisition module 510 is used to acquire a captured image, wherein the captured image is obtained by photographing the pole piece and the pole ear under the irradiation of a laser generator;

[0064] An image extraction module 520 is used to extract the laser pattern in the captured image to obtain actual laser pattern parameters;

[0065] The tab folding determination module 530 is used to determine whether the tab is folded according to the actual laser pattern parameters.

[0066] In some embodiments, the tab folding determination module may include:

[0067] A standard laser parameter acquisition submodule is used to obtain preset standard laser parameters;

[0068] The tab folding determination submodule is used to determine whether the tab is folded according to the comparison result of the actual laser pattern parameters and the standard laser parameters.

[0069] In some embodiments, the actual laser pattern parameters include at least one of the following: an actual maximum laser line length and an actual maximum laser intermediate fault spacing, and the standard laser parameters include at least one of the following: a standard laser line length and a standard laser intermediate fault spacing;

[0070] Accordingly, the tab folding determination submodule may include:

[0071] A first tab folding determination unit is used to determine that the tab is folded when the actual maximum length of the laser line is less than a first preset ratio of the standard laser line length; or

[0072] The second pole tab folding determination unit is used to determine that the pole tab is folded when the actual maximum laser intermediate fault spacing is greater than a second preset ratio of the standard laser intermediate fault spacing.

[0073] Regarding the device in the above embodiment, the specific manner in which each module performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0074] The present application also provides a tab folding detection system. Figure 2 As shown, the system may include:

[0075] A laser generator, used for irradiating the pole piece and the pole lug to be photographed, and forming a laser pattern on the pole piece and the pole lug;

[0076] A camera, used for photographing the pole piece and the pole lug to obtain photographed images of the pole piece and the pole lug;

[0077] A controller is used to execute the tab folding detection method described in any one of the embodiments of the present application.

[0078] In an embodiment of the present application, the tab folding detection system may further include an infrared filter, and the infrared filter is located in front of the lens of the camera, so that the laser light emitted by the laser generator can be better imaged in the camera.

[0079] In the embodiment of the present application, the laser pattern may be a laser line, and the width of the laser line is less than or equal to 0.5 mm. In this way, the influence of the laser line on the data can be reduced as much as possible while the laser line can be seen clearly.

[0080] In the embodiment of the present application, the laser generator is located directly above the pole piece and the pole ear, and the camera is located on one side of the laser generator for photographing the pole piece and the pole ear at an angle.

[0081] In a specific embodiment, as Figure 2 shown, the working process of the pole ear folding detection system may include the following steps:

[0082] (1) Rigidly fix the laser generator and the camera, and adjust the positions of both to ensure clear imaging and that the laser can irradiate the pole piece and the pole ear;

[0083] (2) Install an infrared filter on the lens of the camera;

[0084] (3) Collect and calibrate the standard pole piece, and extract the standard laser pattern such as the standard laser line;

[0085] (4) Calculate the standard laser line length LA and the standard laser middle fault spacing KA of the standard laser line;

[0086] (5) When officially starting the detection or operation, collect each frame of image, and extract the laser pattern in each frame of image to obtain the maximum actual laser line length LB of each frame of image;

[0087] (6) Determine whether the condition LB < LA * 0.8 is satisfied. If so, the test fails, that is, it is determined that the pole piece has been folded; if this condition is not satisfied, then step (7) is executed;

[0088] (7) Obtain the maximum actual laser middle fault spacing and denote it as KB;

[0089] (8) Determine whether the condition KB > KA * 1.5 is satisfied. If so, the test fails, that is, it is determined that the pole piece has been folded; if this condition is not satisfied, it means that the pole piece has not been folded.

[0090] That is to say, only when neither the condition LB < LA * 0.8 nor the condition KB > KA * 1.5 is satisfied can it be determined that the pole piece has not been folded. On the contrary, as long as either of the two conditions is satisfied, it can be determined that the pole piece has been folded.
