Description

Technical Field

[0001] The present application relates to the coating field, and in particular to a coating system and a coating method. Background Art

[0002] Electrode plates are the basis of power batteries and affect the electrochemical performance and safety of power batteries. Electrode plates usually include a current collector and a coating applied on the current collector. Currently, the electrode plates are usually prepared by a coating process in which a slurry is applied on the current collector, the organic solvent in the slurry is dried, and the coil is rolled up by a winding device.

[0003] The start or end of reeling of the reeling device is usually controlled manually, that is, the reel change is determined manually, which results in a relatively low degree of automation of the reeling device.

[0004] The above statements are only used to provide background information related to the present application and do not necessarily constitute prior art. Summary of the invention

[0005] In view of the above problems, the embodiments of the present application provide a coating system and a coating method to improve the automation level of roll changing.

[0006] In a first aspect of an embodiment of the present application, a coating system is provided, comprising:

[0007] Winding device, driving device, unwinding device and coating machine controller;

[0008] The driving device is used to drive the material unwound by the unwinding device to move toward the rewinding device, and the rewinding device is used to rewind the material;

[0009] The coating machine controller is used to obtain the state parameters of each clamping head for clamping the roll in the winding device, and determine the target roll to be wound in the winding device based on the state parameters; when it is determined that the current coating process parameters meet the roll changing conditions, the winding device is controlled to change the roll so as to wind the material through the target roll.

[0010] In the solution provided by this embodiment, the target roll to be wound is determined based on the state parameters of each clamping head for clamping the roll in the winding device; when it is determined that the current coating process parameters meet the roll-changing conditions, the winding device is controlled to change the roll so as to wind the material through the target roll. Through the state parameters, coating process parameters and roll-changing conditions, the winding device is automatically switched to the target roll to wind the material, which greatly improves the automation of roll changing.

[0011] In some embodiments, the coater controller is used to:

[0012] Obtaining the roll diameter of the target roll;

[0013] From the roll-changing conditions, a target roll-changing condition having a mapping relationship with the roll diameter of the target roll is acquired;

[0014] In the case where it is determined that the current coating process parameters meet the target roll-changing condition, it is determined that the current coating process parameters meet the roll-changing condition.

[0015] In the solution provided by this embodiment, the target roll-changing condition is determined by the roll diameter of the target roll, and the target roll-changing condition is used to judge the current coating process parameters. Since the target roll-changing condition matches the roll diameter of the target roll, compared with judging the current coating process parameters by using other roll-changing conditions that do not match the roll diameter of the target roll, the target roll-changing condition of this embodiment can make the judgment result more accurate.

[0016] In some embodiments, the coating system further comprises:

[0017] A cutter device, used to cut off the material passing through the cutter device when it is determined that the current coating process parameters meet the roll-changing conditions;

[0018] The coating machine controller is used to:

[0019] detecting a cutting action of the cutter device and determining that the coating process parameters meet the target roll-changing condition;

[0020] Based on the fact that the cutting action of the cutter device is not detected and the coating state parameters included in the coating process parameters satisfy the target roll-changing condition, it is determined that the coating process parameters satisfy the target roll-changing condition.

[0021] In the solution provided in this embodiment, it is clearly defined that the target roll changing condition is determined based on the cutting action of the cutter device and the coating state parameters, which not only realizes automatic roll changing but also makes the solution simple and easy to implement, and can be more applicable to actual working conditions.

[0022] In some embodiments, the coater controller is further configured to:

[0023] When it is determined that the current coating process parameters meet the roll-changing condition, a roll-changing signal is generated, where the roll-changing signal is used to indicate the acquisition of film roll list information of the material wound on the target roll.

[0024] In the solution provided by the present embodiment, compared with manually changing the roll and manually going to the upper computer of the coating system to manually operate and establish a new film roll list, the present embodiment controls the winding of the target roll and generates a roll change signal to generate film roll list information of the material wound by the target roll, which greatly shortens the interval between the winding of the roll material and the establishment of the film roll list and improves the consistency between the roll material on the target roll and the film roll list information.

[0025] In some embodiments, the coating system further comprises a process control system;

[0026] The coating machine controller is also used for:

[0027] When it is determined that the process control system has obtained the film roll list information based on the roll change signal, the state parameters corresponding to the clamping head clamping the target roll are updated.

[0028] The solution provided in this embodiment updates the state parameters corresponding to the chuck of the target roll, which can not only promote the subsequent accurate determination of the new target roll, but also the timing of this update can reduce unnecessary processing procedures. For example, if the state parameters are updated after a period of time after the film roll order information is obtained, then when the new target roll is determined subsequently, the current target roll will inevitably be determined as the new target roll. Although the current target roll can be excluded through the subsequent roll changing conditions, both the exclusion process and the process of determining it as the new target roll will complicate the entire process.

[0029] In some embodiments, the coater controller includes a display screen, the display screen is used to display a film roll management interface, the film roll management interface includes a mode configuration component;

[0030] The coating machine controller is used to obtain the state parameters of each clamping head for clamping the roll in the winding device when the user configures the winding mode of the target roll to be automatic mode through the mode configuration component, and determine the target roll to be wound in the winding device based on the state parameters; and control the winding device to change the roll so as to wind the material through the target roll when it is determined that the current coating process parameters meet the roll changing conditions.

[0031] In the solution provided in this embodiment, the mode configuration component allows the user to select manual roll change or automatic roll change according to actual needs, which helps to improve the flexibility of roll change.

[0032] In some embodiments, the film roll management interface further includes a roll diameter display component;

[0033] The roll diameter display component is used for the user to configure the roll diameter threshold value in the roll changing condition.

[0034] In the solution provided in this embodiment, a roll diameter display component is provided on the film roll management interface so that the user can configure the roll diameter threshold in the roll changing condition, which helps the user to set the roll changing condition according to his own needs.

[0035] In some embodiments, the film roll management interface further includes a new film roll component and a roll change signal invalid display component;

[0036] The coating machine controller is also used for, when the target roll is not an empty roll, detecting a new film roll instruction triggered by the user through the new film roll component within the preset time length of generating the roll change signal, and marking the roll change signal as valid when the new film roll instruction is detected; when the new film roll instruction is not detected within the preset time length of generating the roll change signal, displaying indication information indicating that the roll change signal is invalid through the roll change signal invalid display component, and setting identification information for representing the use of the film roll single information in the most recent winding process.

[0037] In the solution of this embodiment, the roll change signal is marked by the new film roll instruction of the new film roll assembly, so that the accuracy of the film roll list information of the target roll can be improved.

[0038] In some embodiments, the coater controller is used to:

[0039] When the target menu item selected in the menu bar of the interface of the display screen is automatic control, and the submenu item selected in the target menu item is film roll list information, the film roll management interface is displayed.

[0040] In the solution provided in this embodiment, the setting of menu items and submenu items in the interface of the display screen enables the interface of the display screen to not only display the film roll management interface, but also display other interfaces as required, which helps to improve the utilization rate of the display screen.

[0041] In some embodiments, the winding device comprises:

[0042] A turret, a first rotating shaft and a second rotating shaft disposed on the turret, a first chuck disposed on the first rotating shaft, and a second chuck disposed on the second rotating shaft;

[0043] The first chuck is used to clamp the first reel, and the second chuck is used to clamp the second reel;

[0044] The coating machine controller is used to obtain the state parameters of the first chuck and the second chuck; and determine the target roll from the first roll and the second roll based on the state parameters of the first chuck and the second chuck.

[0045] The winding device provided in this embodiment supports multiple reels through the structure of the turret and the rotating shaft, laying a foundation for automatic roll changing.

[0046] In some embodiments, the coating system further comprises:

[0047] Coating die and coating oven;

[0048] The coating die head is used to coat the material passing through the coating die head;

[0049] The coating oven is used to bake the material coated by the coating die head.

[0050] In the solution provided in this embodiment, coating the material through a coating die head and a coating oven helps to improve the coating efficiency of the coating system for coating the material.

[0089] Energy conservation and emission reduction are the key to the sustainable development of the automobile industry. Electric vehicles have become an integral part of the sustainable development of the automobile industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is another reference factor related to their development.

[0090] Electrode plates are the basis of power batteries and affect the electrochemical performance and safety of power batteries. Electrode plates usually include a current collector and a coating applied on the current collector. Currently, the electrode plates are usually prepared by a coating process in which a slurry is applied on the current collector, the organic solvent in the slurry is dried, and the coil is rolled up by a winding device.

[0091] The start or end of winding of the winding device is usually controlled manually, so multiple reels can be installed in the winding device, and multiple rotating drums can be switched with each other to achieve winding, and the switching of the reels is also manually judged and achieved, which leads to a relatively low degree of automation of the winding device.

[0092] In order to improve the automation of roll changing, one or more embodiments of the present application provide a coating system, which determines the target roll to be wound based on the state parameters of each chuck used to clamp the roll in the winding device; when it is determined that the current coating process parameters meet the roll changing conditions, the winding device is controlled to change the roll to wind the material through the target roll. Through the state parameters of each chuck, the coating process parameters and the roll changing conditions, the winding device is automatically switched to the target roll to wind the material, which greatly improves the automation of roll changing.

[0093] The coating system disclosed in the embodiment of the present application includes but is not limited to winding up materials such as paper, cloth, plastic film, current collector, battery electrode, etc., and during the winding process, controlling the winding device to achieve automatic roll changing.

[0094] like Figure 1 As shown, the coating system may include:

[0095] A winding device 11, a driving device 12, an unwinding device 13 and a coating machine controller 14;

[0096] The driving device 12 is used to drive the material unwound by the unwinding device 13 to move toward the rewinding device 11, and the rewinding device 11 is used to rewind the material;

[0097] The coating machine controller 14 is used to obtain the state parameters of each clamping head for clamping the roll in the winding device 11, and determine the target roll to be wound in the winding device 11 based on the state parameters; when it is determined that the current coating process parameters meet the roll changing conditions, the winding device 11 is controlled to change the roll so as to wind the material through the target roll.

[0098] In this embodiment, the state parameter of the chuck indicates whether the chuck holds a reel or not. When a reel needs to be clamped by one chuck, the state parameter of the chuck determines whether the reel is a target reel; when a reel needs to be clamped by multiple chucks, the state parameters of multiple chucks jointly determine whether the reel is a target reel. For example, it can be set that only when the state parameters of multiple chucks all indicate that the chucks hold a reel, the reel is determined to be a target reel.

[0099] In this embodiment, different state parameters of the chuck can be distinguished by different parameter values. For example, when the parameter value of the state parameter is 1, it means that the state parameter indicates that the chuck holds the reel, and when the parameter value of the state parameter is 0, it means that the state parameter indicates that the chuck does not hold the reel. Different state parameters of the chuck can also be distinguished by the address storing the state parameter. For example, the state parameter stored at the first address indicates that the chuck holds the reel, and the state parameter stored at the second address indicates that the chuck does not hold the reel.

[0100] In this embodiment, the target reel to be wound is a reel in the winding device that is not currently winding the material. The target reel can be an empty reel or a non-empty reel. The so-called empty reel refers to a reel on which no material is wound. Correspondingly, a non-empty reel refers to a reel on which input material is wound. In practical applications, during the winding process using an empty reel, if it is detected that there is abnormal material in the material being wound, the reel wound with the abnormal material can be removed from the winding device to remove the abnormal material wound on the reel, and then the reel is clamped to the chuck. Since the reel clamped to the chuck is still wound with material in this case, when the reel is determined to be the target reel, the target reel is a non-empty reel.

[0101] In this embodiment, it is possible to determine whether the target roll is an empty roll or a non-empty roll based on the roll diameter of the target roll. For an empty roll, since there is no material wound on the empty roll, the roll diameter of the empty roll is usually within a set roll diameter range, and for a non-empty roll, since there is some material wound on the non-empty roll, the roll diameter of the non-empty roll is larger than the roll diameter of the empty roll, and the roll diameter of the non-empty roll is usually within a set roll diameter range. It should be understood that the minimum value of the roll diameter range used to determine a non-empty roll is greater than the maximum value of the roll diameter range used to determine an empty roll. For example, the roll diameter range used to determine an empty roll can be set to (200, 400), and the roll diameter range used to determine a non-empty roll can be set to [400, +∞), where the unit of the roll diameter is mm.

[0102] In this embodiment, the roll changing condition indicates that the target roll in the winding device is capable of winding the material in the coating system, and no other roll is winding in the winding device. It should be understood that no other roll is winding in the winding device, including the winding of the winding roll has been completed, and other rolls have not started to be wound after being assembled to the winding device through the chuck.

[0103] In actual working conditions, for a roll that is being wound up, whether the winding of the roll is finished is determined by parameters including but not limited to the number of meters of the material wound up by the roll, the length of time the roll is wound up, or the roll diameter of the roll. For example, when the roll starts to be wound up, the time when the roll starts to be wound up is usually recorded, and the number of meters that the roll has been wound up since the start of winding up is counted by a meter counter, and the roll diameter of the roll is counted. Therefore, when the length of time the roll is wound up is calculated based on the time when the roll starts to be wound up> the time threshold, the number of meters of the material wound up by the roll> the meter threshold, or the roll diameter> the roll diameter threshold, it can be determined that the winding of the roll is finished. It should be understood that the roll diameter of the roll is the overall roll diameter of the roll and the material wound on the roll. Among them, the time threshold, the meter threshold, and the roll diameter threshold can all be pre-set based on experience or according to actual needs.

[0104] In actual working conditions, after the winding of other reels is completed, if the target reel is switched to winding, during the winding process of the target reel, the chuck used to clamp other reels will clamp another target reel to be wound so as to switch to winding by the other target reel after the winding of the target reel is completed. In order to reduce the resource consumption of the coating system, the timing of the chuck clamping another target reel, or the timing of controlling the other target reel to be ready for winding after the chuck clamps the other target reel, can be indicated by the winding end time of the target reel. For example, the winding end time of the target reel can be estimated based on the number of meters of material wound on the target reel, the length of time the reel is wound, or the diameter of the reel, and then, based on the winding end time, the preset time is extracted to control the chuck to clamp another target reel or control the other target reel that has been clamped to be ready for winding. Among them, the preset time can be set artificially based on experience or according to actual needs.

[0105] The roll change in this embodiment refers to the winding being performed twice in succession, and the roll that is wound twice in succession can be the same roll or different rolls. Taking the winding device including roll A and roll B as an example, if roll A is determined as the target roll and roll B is winding, and the current coating process parameters meet the roll change conditions, roll A is used for winding. In this case, the rolls that are wound twice in succession are different rolls, that is, one roll A and the other roll B. If roll A is determined as the target roll and roll B is winding, and before the winding of roll B is completed, it is detected that there are abnormal materials in the wound materials on roll B, in this case, roll B needs to be disassembled and the abnormal materials are removed. Then, in order to reduce the waste of materials, roll B, which is still wound with some normal materials after the abnormal materials are removed, is usually reassembled with a recovery roll device, and roll B is continued to be used for winding materials. Usually, when the roll B is removed from the winding device, it is considered that the winding of the roll is completed. Therefore, in this case, the roll wound twice is the same roll.

[0106] In the solution provided by this embodiment, the target roll to be wound is determined based on the state parameters of each clamping head for clamping the roll in the winding device; when it is determined that the current coating process parameters meet the roll-changing conditions, the winding device is controlled to change the roll so as to wind the material through the target roll. Through the state parameters, coating process parameters and roll-changing conditions, the winding device is automatically switched to the target roll to wind the material, which greatly improves the automation of roll changing.

[0107] According to some embodiments of the present application, the coater controller 14 is used to:

[0108] Obtain the roll diameter of the target roll;

[0109] From the roll changing conditions, a target roll changing condition having a mapping relationship with the roll diameter of the target roll is obtained;

[0110] In the case where it is determined that the current coating process parameters meet the target roll-changing conditions, it is determined that the current coating process parameters meet the roll-changing conditions.

[0111] In actual working conditions, when the target roll to be wound is an empty roll, an adhesive area is set on the empty roll. When the target roll is used to wind the material, the tape feeder in the coating system can automatically stick the material to the adhesive area so that the target roll can be used for winding. When the target roll to be wound is a non-empty roll, there are some wound materials on the non-empty roll, so there is no way to set an adhesive area on the non-empty roll, which makes it impossible to automatically stick the material to the target roll through the tape feeder. In this case, manual tape feeding is required, that is, manually sticking the material to the target roll so that the target roll can be used for winding. In these two cases, the roll-changing conditions for judging the current coating process parameters are different. Therefore, when judging whether the current coating process parameters meet the roll-changing conditions, the target roll-changing conditions are first determined based on the roll diameter of the target roll, and then the current coating process parameters are judged whether they meet the roll-changing conditions.

[0112] In this embodiment, the judgment logics in different target roll changing conditions in the roll changing conditions may overlap partially or may be completely different. The coating process parameters involved in different roll changing conditions may overlap or may be completely different.

[0113] In this embodiment, the mapping relationship between the roll diameter and the roll changing condition is preset. In order to simplify the calculation and meet the requirements of actual working conditions, the roll diameter in the preset mapping relationship can actually be a roll diameter interval. For example, the roll diameter interval for determining an empty roll described above corresponds to a roll changing condition, and the roll diameter interval for determining a non-empty roll described above corresponds to a roll changing condition. According to this mapping relationship, when obtaining a target roll changing condition having a mapping relationship with the roll diameter of the target roll, the target roll diameter interval to which the roll diameter of the target roll belongs can be determined first, and then the target roll diameter interval can be used to query the preset mapping relationship to obtain the roll changing condition corresponding to the target roll diameter interval, and the roll changing condition corresponding to the target roll diameter interval can be used as the target roll changing condition.

[0114] In the solution provided by this embodiment, the target roll-changing condition is determined by the roll diameter of the target roll, and the target roll-changing condition is used to judge the current coating process parameters. Since the target roll-changing condition matches the roll diameter of the target roll, compared with judging the current coating process parameters by using other roll-changing conditions that do not match the roll diameter of the target roll, the target roll-changing condition of this embodiment can make the judgment result more accurate.

[0115] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0116] According to some embodiments of the present application, Figure 1 As shown, the coating system may also include:

[0117] A cutter device 15, used to cut off the material passing through the cutter device 15 when it is determined that the current coating process parameters meet the roll-changing conditions;

[0118] The coating machine controller 14 is used for:

[0119] The cutting action of the cutter device 15 is detected, and it is determined that the coating process parameters meet the target roll-changing conditions;

[0120] Based on the fact that the cutting action of the cutter device 15 is not detected and the coating state parameters included in the coating process parameters satisfy the target roll-changing condition, it is determined that the coating process parameters satisfy the target roll-changing condition.

[0121] In this embodiment, the cutting action of the cutter device 15 indicates that the reel being wound in the winding device 11 has been wound up, that is, the cutting action can also be used as a condition for determining whether the reel being wound up has been wound up. When the cutter device 15 has a cutting action, the material transmitted to the cutter device 15 is cut off, so the reel being wound up in the winding device 11 has been wound up.

[0122] In this embodiment, the cutting action of the cutter device 15 can also indicate that the target reel is an empty reel. As mentioned above, in the case where the target reel in the winding device 11 is not an empty reel, the target reel needs to be manually spliced. Therefore, in this case, after the reel being wound in the winding device 11 is wound, it is necessary to stop the entire winding device 11, manually cut the tape, and then splice the target reel. In the case where the target reel in the winding device 11 is an empty reel, since the tape splicing device can automatically splice the target reel, in this case, it is not necessary to stop the winding device 11, directly control the cutter device 15 to cut the tape, and control the splicing device to automatically splice the target reel. Therefore, in the case where there is a cutting action of the cutter device 15, it can be determined that the target reel in the winding device 11 is an empty reel.

[0123] In this embodiment, combined with the foregoing, when the cutter device 15 has a cutting action, the roll being wound in the winding device 11 automatically stops winding. Since the roll being wound has been winding normally before the cutter device 15 is actuated, this indicates that the winding device 11 can operate and wind normally, and the coating equipment in the coating system (such as the coating die head and the slurry valve) is also coating the material normally. Therefore, in this case, once the cutter device 15 is actuated, it is considered that the coating process parameters meet the roll changing conditions and can be wound through the target roll. In the case where the cutter device 15 does not make a cutting action and the winding device 11 needs to be shut down, the coating process parameters before the winding device 11 is shut down are no longer of reference value. In other words, before the winding device 11 is shut down, the winding device 11 can be wound normally and the coating equipment can coat the material normally, but it cannot be guaranteed that after the winding device 11 is shut down and restarted, the winding device 11 can still be wound normally and the coating equipment can still coat the material. Therefore, in this case, it is necessary to use the coating state parameters in the coating process parameters to judge the target roll changing conditions.

[0124] In this embodiment, the coating state parameter is a parameter that affects the coating process. In practical applications, the coating state reference includes but is not limited to the following three aspects: the wound material is coated with slurry, the target roll is not idling, and the target roll is not manually controlled. The wound material is coated with slurry, which can be reflected by the parameters characterizing the working state of the coating die head and / or the parameters characterizing whether the slurry valve is open, the target roll is not idling, which can be reflected by the belt tension, and the target roll is not manually controlled. The speed of the rotating shaft on the turret is used to characterize the non-manual rotation of the reel, the belt tension is used to indicate that the reel is not idling, and the coating die and the slurry valve indicate that it is not idling. In actual working conditions, the speed of the rotating shaft on the turret can be obtained by an encoder, the belt tension can be obtained by a tension sensor, and the working state of the coating die head and the slurry valve can be characterized by the action signals of the coating die head and the slurry valve.

[0125] In this embodiment, based on the specific implementation of the above-mentioned coating state parameters, when it is determined that the rotation speed is greater than the rotation speed threshold, the tape tension is greater than the tape tension threshold, the coating die head is opened and the slurry valve is opened, it is determined that the coating state parameters meet the target roll changing conditions.

[0126] In the solution provided in this embodiment, it is clearly defined that the target roll changing condition is determined based on the cutting action of the cutter device and the coating state parameters, which not only realizes automatic roll changing but also makes the solution simple and easy to implement, and can be more applicable to actual working conditions.

[0127] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0128] According to some embodiments of the present application, the coater controller 14 is further configured to:

[0129] When it is determined that the current coating process parameters meet the roll-changing conditions, a roll-changing signal is generated, and the roll-changing signal is used to indicate the film roll list information of the material wound on the target roll.

[0130] In this embodiment, the film roll list information includes but is not limited to the film roll number, film roll list and other data. Among them, the film roll number is used to uniquely identify the roll of material wound by the target roll. Except for special circumstances, even if the same roll is wound at different times, the corresponding film roll numbers of the rolls are different. Of course, the corresponding film roll numbers of the rolls wound by different rolls are also different. For the special case where the same film roll number may be used for the roll wound twice by the same roll, the roll obtained by the roll in the current winding process has a film roll number. During the winding process, it is detected that there are abnormal rolls in the rolls obtained by winding. At this time, the roll is removed from the winding device to remove the abnormal rolls. In order to reduce the waste of rolls, the roll that is still wound with some normal materials is usually reassembled into the winding device. In this case, when it is necessary to determine the film roll list number of the roll on the roll, the film roll number in the previous winding process can be used. That is, the film roll numbers corresponding to the rolls wound at different times by the same roll are the same.

[0131] In this embodiment, the film roll list corresponds to the film roll number one by one, and is used to record the test data of the coil. In order to understand the quality of the coil, the coating system will detect the material through the detection equipment during the coating process and record the test data. Taking any side of the material as an example, after the slurry is coated on any side through the coating die head and the slurry valve, the weight of the material can be measured by the surface density meter. According to the weight and the original weight of the material, the weight of the slurry coated on any side, the coating density and other parameters can be obtained. These parameters can reflect the quality of the coating and characterize the quality of the coil.

[0132] In this embodiment, the roll change signal is generated by writing data at a specific address or writing data at a set bit of data, including but not limited to, For example, the roll change signal may be generated by writing 1 at a set register address.

[0133] In the solution provided by the present embodiment, compared with manually changing the roll and manually going to the upper computer of the coating system to manually operate and establish a new film roll list, the present embodiment controls the winding of the target roll and generates a roll change signal to generate film roll list information of the material wound by the target roll, which greatly shortens the interval between the winding of the roll material and the establishment of the film roll list and improves the consistency between the roll material on the target roll and the film roll list information.

[0134] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0135] According to some embodiments of the present application, the coating system further includes a process control system 16;

[0136] The coater controller 14 is also used to:

[0137] When it is determined that the process control system 16 has obtained the film roll list information based on the roll change signal, the state parameters corresponding to the clamping head clamping the target roll are updated.

[0138] In this embodiment, the connection state corresponding to the clamp holding the target reel has different meanings before and after the update. For example, if the connection state before the update indicates that the clamp holds the target reel, then the connection state after the update indicates that the clamp does not hold the target reel; conversely, if the connection state before the update indicates that the clamp does not hold the target reel, then the connection state after the update indicates that the clamp holds the target reel.

[0139] The solution provided in this embodiment updates the state parameters corresponding to the chuck of the target roll, which can not only promote the subsequent accurate determination of the new target roll, but also the timing of this update can reduce unnecessary processing procedures. For example, if the state parameters are updated after a period of time after the film roll order information is obtained, then when the new target roll is determined subsequently, the current target roll will inevitably be determined as the new target roll. Although the current target roll can be excluded through the subsequent roll changing conditions, both the exclusion process and the process of determining it as the new target roll will complicate the entire process.

[0140] The above description of various embodiments tends to emphasize the differences between the various embodiments. The same or similar aspects can be referenced to each other, and for the sake of brevity, they will not be repeated herein.

[0141] According to some embodiments of the present application, the coating machine controller 14 includes a display screen, such as Figure 2 As shown, the display screen is used to display a film roll management interface 21, and the film roll management interface 21 includes a mode configuration component 211;

[0142] The coating machine controller 14 is used to execute the steps of obtaining the state parameters of each clamping head for clamping the roll in the winding device when the user configures the winding mode of the target roll to be automatic mode through the mode configuration component 211, and determining the target roll to be wound in the winding device based on the state parameters; and controlling the winding device to change the roll so as to wind the material through the target roll when it is determined that the current coating process parameters meet the roll changing conditions.

[0143] In this embodiment, the mode configuration component 211 includes a roll information display component and a mode selection component, wherein the information displayed by the roll information display component is used to uniquely identify a roll in the winding device, and the mode selection component is used for the user to select the roll changing mode of the roll, and the mode selection component supports the user to select one of the two modes: manual mode and automatic mode.

[0144] In the solution provided in this embodiment, the mode configuration component allows the user to select manual roll change or automatic roll change according to actual needs, which helps to improve the flexibility of roll change.

[0145] According to some embodiments of the present application, Figure 2 As shown, the film roll management interface 21 also includes a roll diameter display component 212;

[0146] The roll diameter display component 212 is used for the user to configure the roll diameter threshold in the roll changing condition.

[0147] In the solution provided in this embodiment, a roll diameter display component is provided on the film roll management interface so that the user can configure the roll diameter threshold in the roll changing condition, which helps the user to set the roll changing condition according to his own needs.

[0148] According to some embodiments of the present application, Figure 2 As shown, the film roll management interface 21 also includes a new film roll component 213 and a roll change signal invalid display component 214;

[0149] The coating machine controller 14 is also used to, when the target roll is not an empty roll, detect a new film roll instruction triggered by the user through the new film roll component 213 within the preset time length of generating the roll change signal, and when the new film roll instruction is detected, mark the roll change signal as valid; when no new film roll instruction is detected within the preset time length of generating the roll change signal, the roll change signal invalid display component 214 displays an indication message indicating that the roll change signal is invalid, and sets identification information for representing the use of the film roll single information in the most recent winding process.

[0150] As mentioned above, the material carried on the roll includes at least the following two situations. The first is that the roll is disassembled from the winding device during the winding process, and after the abnormal materials are removed, it is reassembled into the winding device. The second is that the target roll to be wound carries the material. For the first situation, since the same roll is wound twice, there is no need to waste the process of creating film roll single information to recreate new film roll single information in this case. For the second situation, since it is difficult to clearly know when the material on the target roll is wound, it is necessary to create the process of creating film roll single information to recreate new film roll single information when the target roll is wound. Based on the existence of at least two situations above, within the preset time length of generating the roll change signal, the new film roll instruction triggered by the user through the new film roll component distinguishes whether the film roll single information corresponding to the target roll is automatically generated. When the new film roll instruction triggered by the user is received within the preset time length, the roll change signal is marked as valid so as to automatically generate the film roll single information corresponding to the target roll.

[0151] In the solution of this embodiment, the roll change signal is marked by the new film roll instruction of the new film roll assembly, so that the accuracy of the film roll list information of the target roll can be improved.

[0155] In the solution provided in this embodiment, the setting of menu items and submenu items in the interface of the display screen enables the interface of the display screen to not only display the film roll management interface, but also display other interfaces as required, which helps to improve the utilization rate of the display screen.

[0180] Based on the fact that the cutting action of the cutter device is not detected and the coating state parameters included in the coating process parameters meet the target roll-changing conditions, the coating machine controller determines that the coating process parameters meet the target roll-changing conditions.

[0190] When the target menu item selected in the menu bar of the interface of the display screen is automatic control, and the submenu item selected in the target menu item is film roll list information, the film roll management interface is displayed.

[0191] The following is a specific example to illustrate the analysis process of the coating method, see Figure 6 The flowchart shown in the figure shows that the specific example includes the following steps:

[0192] Step 601, the winding device has an automatic roll changing function;

[0193] Step 602: Check whether the automatic roll changing function is enabled. If yes, go to step 603; otherwise, go to step 610.

[0194] Step 603, pre-rewinding the reel on the A axis in the rewinding device;

[0195] Step 604, judging the action of the A-axis based on the state parameters of the chuck on the A-axis;

[0196] Step 605, when the state parameter of the chuck on the A-axis indicates that the chuck on the A-axis is tightening the reel, the pre-reel change signal position of the A-axis is set to 1;

[0197] Step 606: Based on the pre-roll change signal of the A axis, the roll change logic judgment module determines whether the A axis is the target roll to be changed. If so, execute step 607; otherwise, execute step 608;

[0202] Step 611: In the manual mode, when it is determined that the film roll needs to be ended, a film roll end signal is sent.

[0203] The pre-roll change signal refers to the state parameter of the chuck of the roll.

[0204] Wherein, the A axis is any rotating axis in the roll changing device.

[0205] Among them, Figure 7 As shown, the judgment process in the roll change logic judgment module in step 606 may include the following steps:

[0206] Step 701: Based on the pre-roll change signal of the A axis, determine whether the A axis has a roll clamped; if so, execute step 702;

[0207] Step 702, obtaining the roll diameter of the A-axis roll;

If so, execute step 712;

[0218] Wherein, the first value is greater than the second value. If the judgment result in step 702, step 703-step 705, step 709, step 711 and step 712 is no, the process ends.

[0219] Below Figure 3 and Figure 4 Taking a coating system including two rotating shafts as an example, various schemes of executing the roll changing method in one or more embodiments of the present application are described.

[0220] for Figure 1 For the convenience of introduction, the A-axis and the B-axis are assumed to have a chuck on each axis, and the state parameters of the chuck determine whether it clamps the roll. Then, in the solution of the roll changing method of the embodiment of the present application, the state parameters of the chucks of the A-axis and the B-axis have the following three combinations.

[0221] In the following, A-axis N represents the state parameter of the chuck on the A-axis, B-axis N represents the state parameter of the chuck on the B-axis, A-axis 1 represents that the chuck on the A-axis clamps the roll, A-axis 0 represents that the chuck on the A-axis does not clamp the roll, B-axis 1 represents that the chuck on the B-axis clamps the roll, and B-axis 0 represents that the chuck on the B-axis does not clamp the roll.

[0222] The first combination: A axis 1, B axis 0.

[0223] In this combination, there are two options:

[0224] The first solution: the B axis is winding, and there is a new roll on the A axis. At this time, the A axis is judged whether to start the roll changing method process. If the roll diameter of the A axis roll is greater than the first value (the first value indicates that the A axis is not an empty roll), since the A axis cannot use automatic tape connection, it can only be connected manually. Manual tape connection requires the winding device to be stopped, the B axis tape is cut off and connected to the empty A axis roll, and then the A axis roll is used for winding only after it is determined that the A axis speed, tape tension, and the coating die head feed and slurry valve in the coating system meet the roll changing conditions. Among them, the speed of the A axis meets the winding conditions, which means that the roll is not manually turned and adjusted, the tape tension indicates that the belt has connected the material to the roll, the roll is not rotating empty, and the coating die head feed and slurry valve are open, which means that the tape is not empty. After these conditions are met, a new film roll is manually selected based on the display interface.

[0225] If the roll diameter of the A-axis roll is not greater than the first value and greater than the second value, the first value is greater than the second value (indicating that the A-axis roll is an empty roll), the B-axis is winding, and the cutter action is considered to be automatic roll change. If there is no cutter action, after the B-axis is wound, it needs to be stopped before it can be manually connected to the A-axis. The A-axis (A-axis speed, tape feeding tension, coating die head feed and slurry valve) meets the roll change conditions and the A-axis is wound.

[0226] The second solution: There is no roll on the B axis or the roll has been wound for a period of time. In this case, the B axis will not rotate at the set tape speed and can only rotate manually at a low speed. If a new roll is put on the A axis, if the roll diameter of the A axis roll is greater than the first value, it can only be connected manually. Generally, after the A axis has wound a certain length, it is found that the material is abnormal. After opening the chuck and removing the roll, the abnormal material is removed, and the roll is put back on the A axis. After the conditions (A axis speed, tape tension, coating die feed and slurry valve) are met, a pop-up window will pop up to choose to continue film winding. If the roll diameter of the A axis roll is not greater than the first value and greater than the second value, the first value is greater than the second value (indicating that the A axis roll is an empty roll), because the B axis is empty or the winding is completed, the speed does not match, and it can only be connected manually. When the conditions (A axis speed, tape tension, coating die feed and slurry valve) are met, the A axis will wind it.

[0227] The second combination is A axis 0, B axis 1. This combination is similar to the first combination and the relevant principles are the same, so it will not be explained in detail here.

[0228] The third combination: A axis 1, B axis 1

[0229] In this combination, there are two options:

[0230] In the first option, there is a new empty roll on the A axis and a new empty roll on the B axis. At this time, the roll diameter will not be greater than the first value and greater than the second value. Since the other axis is not automatically reeling, it can only be manually connected. Whichever axis first meets the conditions (rotation speed, tape tension, coating die head feed and slurry valve) will be used for reeling.

[0231] In the second solution, the reel of A axis is not empty, and the reel of B axis is newly empty. In this case, A axis will be used first and needs to be manually connected. After A axis meets the conditions, a manual window will pop up to select a new film roll number (if it is an empty foil) or continue the film roll number (if the abnormal material is removed and re-rolled). In special cases, B axis can be used for rewinding. At this time, B axis is an empty reel. If A axis has matched the speed (indicating that A axis is manually connected and has been rewinding foil without coating, usually only in the debugging stage), B axis can automatically connect and change the roll and create a new film roll number. If A axis is not running, B axis can only be manually connected. After the conditions are met, the reel change signal is triggered.
