[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0041] The flying marking method for electrode sheets provided in this application embodiment can be applied to... Figure 1 In the system architecture shown, such as Figure 1As shown, the system may include: a server, a terminal, a marking device, and an image acquisition device. The server can be a physical server, a server cluster consisting of multiple physical servers, or a distributed system. It can also be a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, content delivery networks (CDNs), and big data and artificial intelligence platforms. The terminal may be a user equipment (UE) such as a mobile phone, smartphone, laptop, digital radio receiver, personal digital assistant (PDA), tablet computer (PAD), handheld device, in-vehicle device, wearable device, computing device, or other processing device connected to a wireless modem, mobile station (MS), mobile terminal, etc. The terminal and server can be directly or indirectly connected via wired or wireless communication methods; this application does not limit the connection.
[0042] The terminal is used to receive the attribute information and coding information of the electrode to be processed, and send the attribute information and coding information of the electrode to be processed to the server.
[0043] The server is used to receive the attribute information and marking information of the electrode to be processed, and to execute the flying marking method for the electrode provided in this application to determine the marking parameters and send the marking parameters to the marking equipment.
[0044] The marking equipment receives marking parameters and marks the electrode sheet to be processed according to the marking parameters to obtain a marked electrode sheet containing multiple marks. The marking equipment can use a MOPA green laser and amplify the Gaussian spot through an optical path design method using optical lenses.
[0045] An image acquisition device is used to acquire image information of multiple identifiers in an identifier electrode and send the image information to a server.
[0046] With the rapid development of the lithium battery industry, the coating speed of battery electrode production is increasing, and the requirements for product performance tracking are becoming more stringent. Defect tracking for each segment of the electrode during production is also becoming increasingly important. Traditional inkjet printing methods can no longer meet current application needs. To address the issue of marking the identification number of the entire roll of material during high-speed coating of battery electrodes, this application provides a flying marking method for electrodes, solving the aforementioned problems in existing technologies and improving electrode production efficiency while ensuring marking accuracy.
[0047] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application. Furthermore, the embodiments and features in the embodiments of this application can be combined with each other without conflict.
[0048] Figure 2 This is a schematic flowchart illustrating a method for marking electrodes in flight, provided as an embodiment of this application. Figure 2 As shown, the method may include:
[0049] Step S210: Obtain the attribute information and coding information of the electrode to be processed.
[0050] The attribute information includes electrode thickness, electrode hardness, moving speed, and electrode position.
[0051] The coded information includes different identifiers and the spacing between them; furthermore, the identifier information also includes identifier fields and the spacing between them.
[0052] In some embodiments, a modeling model can also be used to process the width and length information of the identification field in the identification information and the field spacing between each field, simulate and determine the overall width and overall length of the identification information, and compare the overall width and overall length with the corresponding preset width and preset length. If the difference between the overall width and overall length and the corresponding preset width and preset length is within the threshold range, it indicates that subsequent steps can be performed according to the identification field and the field spacing between each field; if it is not within the threshold range, it indicates that the width and length information of the identification field and the spacing between each field are adjusted so that the difference between the overall width and overall length and the corresponding preset width and preset length is within the threshold range.
[0053] Step S220: For any identification information, adjust the standard laser intensity based on the laser intensity coefficient of the determined identification information to determine the target laser intensity.
[0054] Wherein, the laser intensity coefficient M is:
[0055] M=(E / E0+G / G0)×ε
[0056] Where E is the electrode thickness, E0 is the preset standard thickness, G is the electrode hardness, G0 is the preset standard hardness, and ε is the preset laser intensity influence coefficient. The preset laser intensity influence coefficient is determined based on relevant parameters such as environmental parameters and marking equipment parameters during historical operations.
[0057] The target laser intensity is then determined by multiplying the laser intensity coefficient by the standard laser intensity.
[0058] In some embodiments, the target laser intensity is compared with a preset maximum laser intensity. If the target laser intensity is not greater than the preset maximum laser intensity, the current target laser intensity is determined as the target laser intensity. If the target laser intensity is greater than the preset maximum laser intensity, the preset maximum laser intensity is determined as the target laser intensity.
[0059] Step S230: Use preset parameters to determine the model, process the moving speed, electrode position, marking information and marking spacing to obtain marking parameters.
[0060] The marking parameters include time parameters and position parameters; the time parameters are used to control the timing of the laser output by the marking equipment; the position parameters are used to control the optical path direction and / or optical path position of the laser output by the marking equipment.
[0061] The training process of the model, which is determined by preset parameters, is as follows:
[0062] Obtain training samples corresponding to different historical electrode patches; the training samples include historical movement speed, historical electrode patch position, historical identifier field, historical field spacing and historical identifier spacing.
[0063] Based on historical movement speed, historical electrode position, historical identifier field, historical field spacing, and historical identifier spacing, the preset parameter determination model is trained to obtain the trained preset parameter determination model.
[0064] Furthermore, training samples corresponding to different historical electrode patches are obtained. Each training sample includes historical movement speed, historical electrode patch position, historical identifier field, historical field spacing, and historical identifier spacing.
[0065] It is understandable that the data in each training sample can be represented as a vector composed of different data.
[0066] Since the number of training samples is limited, we can use the existing training samples to obtain data samples of the same category as the existing training samples, and use a preset clustering algorithm to cluster the data samples of the same category to obtain the first data cluster after clustering.
[0067] For each first data cluster, determine the new data sample corresponding to the first data cluster based on its cluster center a and cluster radius r.
[0068] Specifically, a, randomly generates an influence factor S, where S∈[0,1].
[0069] b, generate a new sample x′=c+S×r×Δ, where Δ is a random vector that follows a Gaussian or uniform distribution.
[0070] Furthermore, the newly generated data samples are added to the existing training samples to obtain the initial training sample set.
[0071] In some embodiments, the removal of redundant data and outliers from the current training sample set specifically includes: performing max-min normalization on the expanded balanced sample dataset to obtain an updated initial training sample set.
[0072] After data normalization, redundant data in the updated initial training sample set is removed, and outliers are removed to obtain the preprocessed target training sample set.
[0073] Each training sample in the target training sample set is selected as the current training sample.
[0074] Then, the model with preset parameters to be trained is trained to obtain the trained model with preset parameters.
[0075] The process of determining the preset parameters of the model to be trained can be based on a Hidden Markov Model (HMM). The current training samples are processed to obtain the corresponding historical labeling parameters; subsequently, the model parameters are determined to obtain the trained model with the preset parameters. This process employs unsupervised learning to determine the model with the preset parameters.
[0076] In some embodiments, the Hidden Markov Model can incorporate the ICP algorithm to process relevant positional parameters such as the position of the image acquisition device and the position of the electrode, thereby determining the positional parameters of the laser.
[0077] Furthermore, validation datasets can be used to evaluate the trained model, employing common evaluation metrics such as mean squared error (MSE) and mean absolute error (MAE) to assess the model's predictive performance.
[0078] Next, the marking parameters can be determined, which means inputting the moving speed, electrode position, marking information and marking spacing into the trained preset parameter determination model to obtain the marking parameters.
[0079] Step S240: Based on the target laser intensity, time parameters, and position parameters, control the marking equipment to mark the electrode sheet to be processed, and obtain a marked electrode sheet including multiple marks.
[0080] Specifically, after determining the target laser intensity, time parameters, and position parameters, the server sends these parameters to the marking device. The marking device then marks the electrode according to the received parameters. The marking process can be understood as follows: as the electrode moves continuously, the marking device emits a laser of the target laser intensity at the corresponding time point (determined by the time parameters) based on the marking field. Then, based on the field spacing, the next marking field, and the next time point, it emits a laser of the target laser intensity at the next position on the electrode, thus completing one marking. This process is repeated for all marking information based on the spacing between the markings.
[0081] In some embodiments, after obtaining the identifier electrode including multiple identifiers, the method may further include:
[0082] Image information corresponding to multiple identifiers is acquired through image acquisition equipment.
[0083] For any given image information, the image information is processed to determine the sharpness of each identifier field in the image information and the target spacing between each identifier field.
[0084] The average sharpness of multiple identifier fields in the image information is determined as the identifier sharpness of the image information.
[0085] The target spacing between each identifier field is compared with the corresponding field spacing to determine the target ratio between each target spacing and the corresponding field spacing.
[0086] The parameters of the preset parameter determination model are adjusted based on multiple target ratios and sharpness to obtain the adjusted preset parameter determination model.
[0087] This method incorporates a feedback mechanism to adjust preset parameters and determine the model's parameters, thereby obtaining more accurate time and location parameters.
[0088] In some embodiments, the identification information may be displayed on the electrode in the form of a dot matrix DM code (QR code) or text.
[0089] This application provides a method for marking electrodes in flight. The method includes acquiring attribute information and marking information of the electrode to be processed; for any given marking information, adjusting the standard laser intensity based on the determined laser intensity coefficient of the marking information to determine the target laser intensity; using a preset parameter determination model to process the moving speed, electrode position, marking information, and marking spacing to obtain marking parameters; and controlling the marking device to mark the electrode to be processed according to the target laser intensity, time parameters, and the position parameters to obtain a marked electrode including multiple markings. This method ensures the clarity and accurate positioning of the markings while also maintaining the electrode turnover speed, further improving the production efficiency of the electrode.
