[0083] The present application discloses an automatic deviation correction method and device for a battery winding machine, which reduces the occurrence of wrinkles on the head of the battery winding machine, improves the winding quality of the material line, and thus improves the performance and life of the battery.

[0084] Embodiment 1

[0085] See also Figure 1 , Figure 1 This is a flow chart of an automatic deviation correction method for a battery winding machine disclosed in an embodiment of the present application. Optionally, the method can be implemented by a winding deviation correction device, which can be integrated in the battery winding machine, or a local server or cloud server for processing the winding process of the battery core material line, etc., which is not limited in the embodiment of the present application. Figure 1 As shown, the automatic deviation correction method of the battery winding machine may include the following operations:

[0086] 101. When the battery winding machine is performing a winding operation on the current battery core material line, the insertion position parameters of the current battery core material line identified by the insertion mechanism of the battery winding machine are obtained.

[0087] In the embodiment of the present application, optionally, the current battery core material line may include a positive electrode sheet, a negative electrode sheet and a separator. Specifically, the plug-in position parameter of the current battery core material line is used to indicate the relative position parameter between the first target point of the current battery core material line and the first position identification point of the plug-in mechanism, wherein, when there are multiple first target points of the current battery core material line, there are also multiple first position identification points of the plug-in mechanism, and the first target point and the first position identification point are in a one-to-one correspondence.

[0088] 102. Obtain the winding position parameters of the current battery core material wire identified by the deviation correction mechanism of the battery winding machine.

[0089] In an embodiment of the present application, specifically, the winding position parameters of the current battery core material line are used to indicate the relative position parameters between the second target point of the current battery core material line and the second position identification point of the correction mechanism, wherein, when there are multiple second target points of the current battery core material line, there are also multiple second position identification points of the correction mechanism accordingly, and the second target point and the second position identification point are in a one-to-one correspondence.

[0090] 103. According to the inserting position parameters and the winding position parameters, it is determined whether the preset winding correction conditions of the inserting mechanism are met.

[0091] 104. When the judgment result is yes, determine the rolling correction parameters of the inserting mechanism, and perform the rolling correction operation on the inserting mechanism according to the rolling correction parameters.

[0092] In the embodiment of the present application, the winding and deviation correction operation of the inserting mechanism can be understood as that through the winding and deviation correction process of the inserting mechanism, the inserting mechanism can normally wind the next battery core material wire.

[0093] Optionally, the winding correction parameters include one or more of correction accuracy parameters, detection distance correction parameters, response time correction parameters, tension control correction parameters, and the like.

[0094] It should be noted that in the prior art, the wrinkling problem of the head is mainly caused by the deviation of the lithium battery material line when it is wound and the inability of the correction mechanism to correct it. Before winding, the sheet needs to be inserted. When the curvature of the material line A≠0, after the sheet is inserted, the curvature forms a material line deviation (for every X-meter movement of the insert, the material line with curvature A will produce a deviation of 4AX). When rolling up, because the head of the material line has been fixed to the inside of the winding core, the correction mechanism cannot correct it, resulting in wrinkles. At present, winding machines in the lithium battery manufacturing industry are unable to identify the deviation of the head of the material line.

[0095] There are two main ways to solve the problem of wrinkles at the winding head. One is to adjust the reference position of the winding equipment's correction mechanism to reduce the deviation when the material line is inserted; the other is to improve the consistency of the material line itself and reduce the deviation when the material line is wound into the roll. However, both methods have shortcomings. The reference position adjustment of the winding equipment's correction mechanism requires continuous attempts to make the correction mechanism adapt to the material line. Since the state of each roll of the material line is different, the adjustment frequency is high, and since it is impossible to measure the adjustment range, it can only be done through continuous attempts, which is troublesome and time-consuming. It is difficult to adjust the consistency of the material line itself. Since there are many factors related to the consistency of the material line, and some factors are contradictory, it is necessary to consider multiple aspects when making improvements.

[0096] It can be seen that the implementation of the embodiment of the present application can determine whether the insertion mechanism is needed to perform winding correction according to the insertion position parameters and winding position parameters of the current battery core material line. If so, the winding correction parameters are determined and the winding correction is performed, which reduces the occurrence of wrinkles on the head of the battery winding machine, improves the winding quality of the material line, and thus improves the battery performance and life.

[0097] Embodiment 2

[0098] See also Figure 2 , Figure 2 This is a flow chart of another automatic deviation correction method for a battery winding machine disclosed in an embodiment of the present application. Optionally, the method can be implemented by a winding deviation correction device, which can be integrated in the battery winding machine, or a local server or cloud server for processing the winding process of the battery core material line, etc., which is not limited in the embodiment of the present application. Figure 2 As shown, the automatic deviation correction method of the battery winding machine may include the following operations:

[0099] 201. When the battery winding machine is performing a winding operation on the current battery core material line, the insertion position parameters of the current battery core material line identified by the insertion mechanism of the battery winding machine are obtained.

[0100] 202. Obtain winding position parameters of the current battery core material wire identified by the deviation correction mechanism of the battery winding machine.

[0101] 203. Obtain historical insertion position parameters of multiple historical battery core material lines identified by the insertion mechanism.

[0102] In the embodiment of the present application, specifically, the historical insertion position parameters of each historical battery core material line are used to indicate the relative position parameters between the first target point of the historical battery core material line and the first position identification point of the insertion mechanism.

[0103] 204. According to the historical plug-in position parameters and the plug-in position parameters of all historical battery core material lines, determine whether the corresponding plug-in deviation threshold value exceeds the historical plug-in position parameters and the plug-in position parameters of all historical battery core material lines.

[0104] In the embodiment of the present application, optionally, the plug deviation threshold exceeding condition includes the plug deviation threshold exceeding times and / or the plug deviation threshold exceeding interval parameter.

[0105] 205. According to the plug-in deviation threshold exceeding condition, determine whether the plug-in deviation threshold exceeding condition matches the preset plug-in deviation expected condition.

[0106] In an embodiment of the present application, for example, when the battery winding machine is in the winding process, its insertion mechanism recognizes that in the historical battery cell material line and the current battery cell material line, there are Y consecutive material line insertion position points with fluctuation values ​​less than ±X, then it can be determined that the current battery cell material line is stable, that is, it can be determined that the insertion deviation threshold exceeds the preset insertion deviation expectation, and then the subsequent winding and correction operation can be performed; and if there are Y consecutive material line insertion position points with fluctuation values ​​greater than ±X, then it can be determined that the material line is abnormal, and then a corresponding abnormal warning is generated to enable the processing personnel to process the material line.

[0107] 206. When it is determined that the insertion sheet deviation threshold value exceeds the insertion sheet deviation expected condition, it is determined that the preset rolling correction condition of the insertion sheet mechanism is met.

[0108] 207. When it is determined that the preset curling correction conditions of the sheet inserting mechanism are met, the curling correction parameters of the sheet inserting mechanism are determined, and according to the curling correction parameters, a curling correction operation is performed on the sheet inserting mechanism.

[0109] In the embodiment of the present application, for other descriptions of step 201, step 202 and step 207, please refer to the detailed description of step 101, step 102 and step 104 in embodiment 1, and the embodiment of the present application will not be repeated.

[0110] It can be seen that the implementation of the embodiment of the present application can determine the situation of exceeding the insertion deviation threshold based on the historical insertion position parameters of the historical battery core material line and the insertion position parameters of the current battery core material line identified by the insertion mechanism, and then determine whether the insertion deviation threshold exceeds the preset insertion deviation expected situation. If so, it is determined that the preset winding and correction conditions of the insertion mechanism are met. In this way, the execution reliability and accuracy of the winding and correction operation of the insertion mechanism can be improved, and then the continuous operation capacity and overall stability of the battery winding machine production line can be improved, thereby improving the overall consistency and reliability of the battery product.

[0111] In an optional embodiment, judging whether a preset winding correction condition of the inserting mechanism is met according to the inserting position parameter and the winding position parameter, further includes:

[0112] Obtain the historical winding position parameters of all historical battery core material wires identified by the deviation correction mechanism;

[0113] According to the historical winding position parameters and winding position parameters of all historical electric core material lines, determining the winding deviation threshold value exceeding conditions corresponding to the historical winding position parameters and winding position parameters of all historical electric core material lines;

[0114] According to the winding deviation threshold exceeding condition, determining whether the winding deviation threshold exceeding condition matches the preset winding deviation expected condition;

[0115] When it is determined that the winding deviation threshold value exceeds the expected winding deviation, it is determined that the preset winding deviation correction condition of the inserting mechanism is met.

[0116] In this optional embodiment, the historical winding position parameter of each historical electric core material line is used to indicate the relative position parameter between the second target point of the historical electric core material line and the second position identification point of the deviation correction mechanism. Optionally, the winding deviation threshold exceeding condition includes the winding deviation threshold exceeding times and / or the winding deviation threshold exceeding interval parameter.

[0117] Similarly, during the winding process of the battery winding machine, if its correction mechanism identifies that in the historical battery cell material line and the current battery cell material line, there are M consecutive material line winding position points with fluctuation values ​​less than ±N, then it can be determined that the current battery cell material line is stable, that is, it can be determined that the winding deviation threshold exceeds the preset winding deviation expectation, and then the subsequent winding correction operation is performed; and if there are M consecutive material line winding position points with fluctuation values ​​greater than ±N, then it can be determined that the material incoming is abnormal, and then a corresponding abnormal warning is generated to enable the processing personnel to handle the material line.

[0118] It can be seen that this optional embodiment can also determine the situation of exceeding the winding deviation threshold based on the historical winding position parameters of the battery core material line and the winding position parameters of the current battery core material line identified by the correction mechanism, and then judge whether the situation of exceeding the winding deviation threshold matches the preset winding deviation expected situation. If so, it is determined that the preset winding correction conditions of the insertion mechanism are met. In this way, the current winding problems of the battery core material line can be predicted more accurately, and then the winding correction operation can be performed after confirming that the battery core material line is stable and has no abnormalities, avoiding unnecessary shutdown inspections and adjustments, and effectively improving production efficiency and capacity.

[0119] In another optional embodiment, determining the curling correction parameters of the inserting mechanism in step 207 includes:

[0120] Obtaining the insert motion parameters of the insert mechanism;

[0121] Determine the first winding influence corresponding to the inserting mechanism according to the inserting movement parameters;

[0122] According to the first winding influence condition, the inserting sheet position parameter and the winding position parameter, the winding correction parameter of the inserting sheet mechanism is determined.

[0123] In this optional embodiment, the winding influence caused by the insertion movement of the insertion mechanism is analyzed. Optionally, the first winding influence includes a first winding tilt condition and / or a first winding wrinkle condition.

[0124] It should be noted that the process of determining the winding correction parameters can adopt the core material line compensation prediction neural network-RNN neural network structure, and its main network structure is a SimpleRNN layer and a Dense layer. Among them, the SimpleRNN layer structure is 5 neuron units, and the data is the material line position parameter A identified by the correction mechanism and the material line position parameter B identified by the insertion mechanism during the core winding process; and the Dense output layer uses a linear activation function to realize the prediction of the next core material line compensation value.

[0125] It can be seen that this optional embodiment can determine the corresponding first winding influence situation according to the insertion movement parameters of the insertion mechanism, and then determine the winding correction parameters of the insertion mechanism according to the first winding influence situation, the insertion position parameters and the winding position parameters. In this way, the deviation value that needs to be adjusted for the subsequent battery core material line can be analyzed, so as to control the position of the battery core material line during insertion more accurately, thereby reducing the occurrence of wrinkling of the head of the battery cell due to correction fluctuations when it is wound.

[0142] It can be seen that this optional embodiment can further enhance the accuracy and adaptability of the battery winding machine's winding correction by refining the execution steps of the insertion mechanism's winding correction operation and introducing considerations of the environmental parameters of the battery winding machine. At the same time, considering the complexity and variability of the working environment of the battery winding machine, the monitoring and adjustment of environmental parameters are also introduced, which can automatically adjust the adjustment parameters of each target device of the insertion mechanism to adapt to the influence of different environmental conditions on the correction effect, thereby not only improving the stability and reliability of the winding correction, but also making the entire production process more flexible and efficient.
