Description

Technical Field

[0001] This disclosure relates to the field of battery manufacturing technology, and in particular to a coating control method, apparatus, coating machine, and storage medium. Background Technology

[0002] Currently, coating machines used in the production of power batteries and energy storage batteries are used for coating with AB films, i.e., double-sided coating technology.

[0003] Currently, manual intervention is used at the head and tail of the coating machine to confirm the cutting operation. When coating begins on side A at the head, the operator manually clicks the die head to initiate the cutting operation. After initial coating, side A undergoes drying in an oven. When the electrode reaches the tail, the operator performs tail coating based on the state of the side A film after the oven drying process, clicking the tail die head to initiate the cutting operation. However, due to fluctuations and randomness in the timing of the A-side joint reaching the tail, misalignment of the A and B side coating joints can occur, resulting in material scrap in that area, such as slurry, copper foil, aluminum foil, and ceramic adhesive. This is collectively referred to as single-sided scrap, causing significant waste in manufacturing costs and time loss in subsequent processes when removing single-sided scrap.

[0004] Therefore, there is an urgent need for a coating control method that can reduce the length of single-sided scrap, thereby reducing economic losses. Summary of the Invention

[0009] In one example, determining whether to control the die head at the tail of the machine to retract and end the coating process based on the detection result includes: If the test result indicates that the oven layer is normal, then it is determined that the die head at the tail of the machine will be retracted at the second retraction moment, and the coating process will end. If the test result indicates an abnormality in the oven layer, the die head at the tail of the machine is retracted, and the coating process is terminated.

[0010] In one example, the method further includes: If an abnormal coating is detected at the tail of the machine, a second retraction signal is generated for the die head at the tail of the machine. According to the second retraction signal, the die head at the tail of the machine is controlled to retract, and the die head at the head of the machine is also controlled to retract.

[0011] In one example, the method further includes: If no coating abnormality is detected in the machine head, normal coating will proceed.

[0012] In one example, the method further includes: If an abnormality is detected in one layer of the oven, the coating process is paused.

[0013] A second aspect of this disclosure provides a coating control device, the device comprising: The first control module is used to control the die head of the machine head to feed when a feed signal of the die head of the machine head is detected, and to obtain the first feed moment of the die head of the machine head feeding. The first determining module is used to determine the first interval time for coating to reach the tail of the machine based on the distance between the head and the tail and the first coating speed; The second determining module is used to determine the second cutting time based on the first cutting time and the first interval duration; wherein the second cutting time is used to characterize the cutting time of the die head at the tail of the machine. The second control module is used to control the die head at the tail of the machine to advance and coat the material at the second infeed moment if the oven layer is detected to be normal.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0022] Currently, manual checks are performed at the head and tail of the coating machine to confirm the cutting operation. For details, please refer to... Figure 1 The diagram shows a layout of a double-layer folding coating apparatus. From... Figure 1As can be seen, when coating begins on side A of the die head, the operator manually clicks the die head infeed button. After initial coating, side A undergoes drying in an oven. When the electrode reaches the tail end of the die, the operator manually performs tail coating based on the state of the film after the oven drying process on side A, clicking the tail die head infeed button. For a clearer explanation, please refer to... Figure 2 The diagram illustrates a double-layer, folded-back coated electrode tape feeding process. Currently, because the initial coating stage relies on manual, subjective cutting, delays can lead to single-sided scrap. To address this issue, please refer to... Figure 3 Specifically, Figure 3 This is a schematic flowchart of a coating control method provided in an embodiment of this disclosure, which can be executed by a coating machine. Figure 3 As shown, the method provided in this embodiment includes the following steps: S301. When the feed signal of the die head is detected, the die head of the machine head is controlled to feed, and the first feed moment of the die head of the machine head is obtained.

[0023] In one example, the die head's feed signal is used to instruct the die head to perform a feed operation. Specifically, the die head's feed signal is sent to the coating machine's PLC. After receiving the die head's feed signal, the coating machine's PLC controls the die head to feed and acquires the first feed moment. For clarity, this first feed moment is denoted as T1.

[0024] S302. Determine the first interval time for coating to reach the tail of the machine based on the distance between the head and tail of the machine and the first coating speed.

[0025] In one example, the distance between the head and tail of the coating unit is fixed, denoted as S. The first coating speed can be set and is constant, denoted as V1. In this embodiment, the first interval T2 for coating to reach the tail can be determined based on S and V1.

[0026] Specifically, T2 = S ÷ V1.

[0027] S303. Determine the second infeed time based on the first infeed time and the first interval duration; wherein, the second infeed time is used to characterize the infeed time of the die head at the tail of the machine.

[0028] In one example, since the coating sequence of the coating machine inherently starts from the die head, it is necessary to calculate the time when it reaches the tail. Let the second entry point be T3, then T3 = T1 + T2. Here, T3 is used to characterize the entry point of the die head at the tail.

[0029] S304. If the first layer of the oven is detected to be normal, the die head at the tail of the machine is controlled to feed at the second feed moment and to perform coating.

[0030] In one example, if the oven layer is detected to be normal, it means that the production line is normal. Then, the die head at the tail end can be reached at the second infeed time T3. The die head at the tail end is controlled to make an infeed at the second infeed time T3 and then perform coating.

[0031] In this embodiment, Figure 4 This diagram illustrates a single-sided scrapping process using manual cutting during the initial coating stage at the machine head. Because the arrival time of the A-side connector at the machine tail is manually determined during this stage, the length of the single-sided scrapping section becomes random. Figure 5 This diagram illustrates a single-sided scrapping process with automatic feed during the initial coating stage of the die head. Because the first feed moment of the die head and the second feed moment of the die tail can be precisely controlled, the single-sided scrapping length during the automatic feed during the initial coating stage can be controlled as the distance between the die head at the head and the die tail. Figure 5 The length of the single-sided scrap shown is the distance from coating A to coating B.

[0032] This disclosure provides a coating control method, which includes: upon detecting a feed signal from the die head of the die-making machine, controlling the die head of the die-making machine to feed, and acquiring a first feed moment of the die head feeding; then determining a first interval time for coating to reach the tail of the die-making machine based on the distance between the die head and the tail of the die-making machine and a first coating speed; further determining a second feed moment based on the first feed moment and the first interval time; finally, if a normal oven layer is detected, controlling the die head of the tail of the die-making machine to feed at the second feed moment and perform coating. Using this technical solution can reduce the length of single-sided scrap, thereby reducing economic losses.

[0033] Figure 6 This illustration shows a schematic flowchart of a coating control method provided by an embodiment of the present disclosure. The embodiments of the present disclosure are optimized based on the above embodiments, and can be combined with various optional solutions from one or more of the above embodiments.

[0034] like Figure 6 As shown, the coating control method may include the following steps: S601. If an abnormal coating is detected in the die head, the first retraction signal of the die head is generated.

[0035] In one example, the coating process is detected using a charge-coupled device (CCD) or areal density instrument. If a coating abnormality is detected at the die head, a first retraction signal is generated to instruct the die head to retract.

[0036] S602. Based on the first retraction signal, control the die head of the machine head to retract, and obtain the first retraction moment of the die head of the machine head retracting.

[0037] In one example, based on the first retraction signal, the die head of the machine head is controlled to retract, and the first retraction moment of the die head retraction is obtained, which is denoted as T4.

[0038] S603. Determine the second retraction time based on the first retraction time; wherein, the second retraction time is used to characterize the retraction time of the die head at the tail of the machine.

[0039] In one example, the second retraction time is used to characterize the retraction time of the die head at the tail of the machine, and here the second retraction time is denoted as T5.

[0040] In one example, the second retraction time is determined based on the first retraction time, including: The second interval time for coating to reach the tail is determined based on the distance between the head and tail of the machine and the second coating speed. The second retraction time is determined based on the first retraction time and the second interval duration; wherein, the second retraction time is used to characterize the retraction time of the die head at the tail of the machine.

[0041] In one example, the second coating speed can be the same as or different from the first coating speed; here, the second coating speed is denoted as V2.

[0042] In one example, the distance between the head and tail of the coating unit is fixed, denoted as S. The second coating speed can be set and is constant. In this embodiment, the second interval T6 for coating to reach the tail can be determined based on S and V2.

[0043] Specifically, T6 = S ÷ V2.

[0044] S604. Test the first layer of the oven and obtain the test results.

[0045] In one example, the purpose of testing a single layer of oven is to detect any abnormalities in the production line process and obtain the test results.

[0046] S605. Based on the test results, determine whether to control the die head at the tail of the machine to retract at the second retraction moment and end the coating process.

[0047] In one example, based on the detection results, determining whether to control the die head at the tail of the machine to retract at the second retraction moment and end the coating process includes: If the test result shows that the first layer of the oven is normal, then the die head at the tail of the machine is controlled to retract at the second retraction moment, and the coating is ended. If the test result indicates an abnormality in the first layer of the oven, the die head at the tail of the machine will be retracted, and the coating process will be terminated.

[0048] In one example, if the test result shows that the oven layer is normal, it means that the coating of the head section is normal. Therefore, the tail die head can be controlled to retract at the second retraction time T5 to end the coating.

[0049] In one example, if the detection result is an abnormality in the oven layer, it means that the coating has already encountered a problem before reaching the tail of the machine. In order to reduce the length of scrap on one side, the die head at the tail of the machine is immediately controlled to retract and the coating is ended.

[0050] For a clearer illustration, see the example below. Figure 7 A schematic diagram of a single-sided scrapping process with automatic tool retraction during an abnormal stage of the machine head is shown, and... Figure 8 The diagram shows a single-sided scrapping procedure involving manual tool retraction during an abnormal stage of the machine head. Figure 8 In the process, when the coating process is stopped or the blade is withdrawn, the information received on the other side comes from walkie-talkies between on-site employees, which also results in delays and untimely feedback.

[0051] In one example, the method also includes: If no coating abnormality is detected at the die head, normal coating will proceed.

[0052] In one example, if no coating abnormality is detected at the die head, it indicates that the production line is normal and no blade retraction operation is required; coating can proceed normally.

[0053] This disclosure provides a coating control method, which includes: if a coating abnormality is detected in the die head, generating a first retraction signal for the die head; controlling the die head to retract according to the first retraction signal; acquiring the first retraction time of the die head retraction; determining a second retraction time based on the first retraction time; detecting a layer oven to obtain a detection result; and determining whether to control the die head at the tail to retract at the second retraction time and end the coating process based on the detection result. This technical solution enables precise die retraction in the die head, effectively reducing the loss of slurry and copper foil.

[0054] Figure 9This illustration shows a schematic flowchart of a coating control method provided by an embodiment of the present disclosure. The embodiments of the present disclosure are optimized based on the above embodiments, and can be combined with various optional solutions from one or more of the above embodiments.

[0055] like Figure 9 As shown, the coating control method may include the following steps: S901. When the feed signal of the die head is detected, the die head of the machine head is controlled to feed, and the first feed moment of the die head of the machine head is obtained.

[0056] In one example, this step can be found in step S301, and will not be repeated here.

[0057] S902. Determine the first interval time for coating to reach the tail of the machine based on the distance between the head and tail of the machine and the first coating speed.

[0058] In one example, this step can be found in step S302, and will not be repeated here.

[0059] S903. Determine the second infeed time based on the first infeed time and the first interval duration; wherein, the second infeed time is used to characterize the infeed time of the die head at the tail of the machine.

[0060] In one example, this step can be found in step S303, and will not be repeated here.

[0061] S904. If the first layer of the oven is detected to be normal, the die head at the tail of the machine is controlled to feed at the second feed moment and to perform coating.

[0062] In one example, this step can be found in step S304, and will not be repeated here.

[0063] S905. If an abnormal coating is detected at the tail, a second retraction signal for the die head at the tail is generated.

[0064] In this embodiment, if a coating abnormality occurs at the tail section, a second retraction signal is generated for the tail die head, which is used to prioritize the processing of the tail die head.

[0065] S906. According to the second retraction signal, control the die head at the tail of the machine to retract, and control the die head at the head of the machine to retract.

[0066] In this embodiment, the die head at the tail of the machine is controlled to retract according to the second retraction signal. Since the coating at the tail of the machine is abnormal, it is unnecessary for the die head at the head of the machine to continue coating. Therefore, the die head at the head of the machine is controlled to retract simultaneously.

[0067] In one example, if an oven malfunction is detected, coating is paused.

[0068] In one example, if an oven malfunction is detected, coating is paused, and the corresponding section of the blade is retracted according to the above description.

[0069] For a clearer illustration, see the example below. Figure 10 The diagram shown illustrates a single-sided scrapping process with automatic tool retraction during an abnormal tail section. Figure 10 It can be seen that the length of a single-sided scrap is controllable. Figure 11 This diagram illustrates a single-sided scrapping procedure involving manual tool retraction during an abnormal tail section. Figure 11 It can be seen that the length of a single-sided scrap is uncertain and may be longer due to human delays.

[0070] This disclosure provides a coating control method, which includes: if a coating abnormality is detected at the tail end of the machine, generating a second retraction signal for the die head at the tail end; and controlling the die head at the tail end to retract according to the second retraction signal, and also controlling the die head at the head end to retract. This technical solution achieves precise retraction of the die head at the tail end, improving the reliability and responsiveness of equipment operation, and effectively saving labor costs.

[0071] Figure 12 This is a schematic diagram of a coating control device provided in an embodiment of this disclosure. This coating control device can be understood as the aforementioned coating machine or some functional modules within the aforementioned coating machine. For example... Figure 12 As shown, the coating control device 120 includes: The first control module 1201 is used to control the die head of the machine head to feed when the feed signal of the die head of the machine head is detected, and to obtain the first feed moment of the die head of the machine head to feed. The first determining module 1202 is used to determine the first interval time for coating to reach the tail based on the distance between the head and tail of the machine and the first coating speed; The second determining module 1203 is used to determine the second cutting time based on the first cutting time and the first interval duration; wherein the second cutting time is used to characterize the cutting time of the die head at the tail of the machine. The second control module 1204 is used to control the die head at the tail of the machine to advance and coat the material at the second infeed moment if the first layer of the oven is detected to be normal.

[0072] In one example, the coating control device 120 includes: The first generation module 1205 is used to generate a first retraction signal for the die head if an abnormal coating is detected in the die head. The third control module 1206 is used to control the die head of the machine head to retract the die head according to the first retraction signal, and to obtain the first retraction moment of the die head of the machine head retracting the die head. The third determining module 1207 is used to determine the second retraction time based on the first retraction time; wherein the second retraction time is used to characterize the retraction time of the die head at the tail of the machine. The first detection module 1208 is used to detect the first layer of the oven and obtain the detection results; The fourth determining module 1209 is used to determine, based on the detection results, whether to control the die head at the tail of the machine to retract at the second retraction moment and end the coating process.

[0073] In one example, the third determining module 1207 is used for: The second interval time for coating to reach the tail is determined based on the distance between the head and tail of the machine and the second coating speed. The second retraction time is determined based on the first retraction time and the second interval duration; wherein, the second retraction time is used to characterize the retraction time of the die head at the tail of the machine.

[0074] In one example, the fourth determining module 1209 is used for: If the test result shows that the first layer of the oven is normal, then the die head at the tail of the machine is controlled to retract at the second retraction moment, and the coating is ended. If the test result indicates an abnormality in the first layer of the oven, the die head at the tail of the machine will be retracted, and the coating process will be terminated.

[0075] In one example, the coating control device 120 includes: The second generation module 1210 is used to generate a second retraction signal for the die head at the tail if an abnormal coating is detected at the tail. The fourth control module 1211 is used to control the die head at the tail of the machine to retract and the die head at the head of the machine to retract according to the second retraction signal.

[0076] In one example, the coating control device 120 includes: The execution module 1212 is used to perform normal coating if no coating abnormality is detected in the machine head.

[0077] In one example, the coating control device 120 includes: The pause module 1213 is used to pause the coating process if an abnormality is detected in the oven layer.
