Description

Technical Field

[0001] The present invention relates to the technical field of battery manufacturing, and in particular to a tab misalignment adjustment device and method. Background Art

[0002] Lithium batteries are used in numerous fields due to their high energy density, environmental friendliness, and long lifespan. A type of lithium battery, spiral wound batteries rely on winding equipment to achieve the winding of the electrode assembly. Winding equipment offers advantages such as efficient battery manufacturing, low cost, and a small footprint, further promoting the development and use of spiral wound batteries.

[0003] During the winding process, the tabs on each layer must be aligned as closely as possible to facilitate subsequent tab welding. However, tab misalignment often occurs after winding, with deviations occurring between the tab areas of different layers. To address this, the winding equipment is typically adjusted during the winding process based on the tab misalignment detected by the electrode assembly.

[0004] The above solutions still have some shortcomings, including (1) the current detection method predicts the tab misalignment results during the winding process. Due to the high winding speed, it cannot accurately represent the actual tab misalignment of the pole group, and thus cannot make accurate adjustments. (2) There is a lag in the adjustment: the adjustment made during the winding process cannot determine the subsequent tab misalignment situation. Therefore, it is impossible to make significant adjustments to the tab misalignment, and it is impossible to completely avoid the occurrence of poor pole group. Summary of the Invention

[0021] The present invention discloses a tab misalignment adjustment method, comprising:

[0022] Step S1: After the electrode assembly is wound, the electrode assembly is removed from the winding needle, and the first and second output rollers are driven by the linear linkage assembly to linearly move away from each other, thereby flattening the electrode assembly toward both sides, and the first output roller and the first side clamping assembly clamp one side of the electrode assembly, and the second output roller and the second side clamping assembly clamp the other side of the electrode assembly;

[0023] Step S2: The monitoring mechanism monitors the misalignment direction of the tabs of the electrode group. The monitoring mechanism issues an instruction according to the misalignment direction of the tabs to activate the rotary linkage assembly. The rotary linkage assembly drives the first output roller and the second output roller to rotate in a specified direction, thereby adjusting the misalignment of the tabs.

[0024] Step S3: When the monitoring mechanism determines that the tab is adjusted into place, the monitoring mechanism issues a command to stop the rotation linkage assembly.

[0025] According to one embodiment of the present invention, step S1 specifically includes: first, inserting the first output roller and the second output roller into the inner layer of the pole group, and making the first side clamping assembly and the second side clamping assembly located at the outer layer of the pole group, driving the first output roller and the second output roller to move linearly away from each other by the linear linkage assembly, thereby making the first output roller and the first side clamping assembly clamp one side of the pole group, and the second output roller and the second side clamping assembly clamp the other side of the pole group, then removing the pole group from the winding needle, and then driving the first output roller and the second output roller to continue to move linearly away from each other by the linear linkage assembly, thereby flattening the pole group toward both sides;

[0026] Alternatively, first remove the pole group from the winding needle, then insert the first output roller and the second output roller into the inner layer of the pole group, and make the first side clamping assembly and the second side clamping assembly located on the outer layer of the pole group, and then use the linear linkage assembly to drive the first output roller and the second output roller to move linearly in the direction away from each other, thereby flattening the pole group toward both sides, and make the first output roller and the first side clamping assembly clamp one side of the pole group, and the second output roller and the second side clamping assembly clamp the other side of the pole group.

[0027] According to one embodiment of the present invention, step S2 specifically includes: monitoring the misalignment direction and misalignment amount of the pole tab of the pole group through a monitoring mechanism, and the monitoring mechanism issues an instruction to make the rotating linkage component work according to the misalignment direction and misalignment amount of the pole tab, and the rotating linkage component drives the first output roller and the second output roller to rotate in a specified direction and a specified angle, thereby adjusting the misalignment of the pole tab.

[0028] According to one embodiment of the present invention, step S2 specifically includes: the first output roller and the second output roller rotate in a specified direction, driving the pole group to rotate in the same direction, and then driving the first side clamping roller of the first side clamping assembly and the second side clamping roller of the second side clamping assembly to rotate in opposite directions. The friction force applied by the first output roller and the second output roller to the inner layer of the pole group is opposite to the direction of the friction force applied by the first side clamping roller and the second side clamping roller to the outer layer of the pole group, thereby adjusting the misalignment of the pole ears.

[0029] The beneficial effects of the present invention are as follows: after the electrode group is wound and taken out, the first output roller, the second output roller, the first side clamping assembly and the second side clamping assembly cooperate to clamp the two sides of the electrode group respectively and flatten the electrode group toward both sides; the monitoring mechanism monitors the electrode tab area of ​​the electrode group. If it is found that the electrode tab area has an ear misalignment, the monitoring mechanism issues an instruction to make the rotary linkage assembly work, and the rotary linkage assembly drives the first output roller and the second output roller to rotate in a specified direction, and cooperates with the first side clamping assembly and the second side clamping assembly to act on the electrode group, so that the layers of the electrode tabs of the electrode group move relative to each other, and finally the ear misalignment adjustment is achieved. After the monitoring mechanism recognizes that the ear is adjusted in place, the operation of the rotary linkage assembly is stopped; the ear misalignment monitoring and adjustment of the electrode group after winding is completed, taken out and flattened can reduce the monitoring accuracy requirement, making it easier to monitor the actual ear misalignment, and the monitoring mechanism adjusts the ear misalignment while monitoring, which also solves the hysteresis problem caused by the ear misalignment adjustment during the winding process, and finally achieves high-precision adjustment of the ear misalignment and reduces the probability of electrode group defects.

However, it should be understood that these practical details are not intended to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not essential. Furthermore, to simplify the drawings, some commonly used structures and components are depicted in simplified schematic form.

[0049] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them.

[0050] Example 1

[0051] like Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of an application scenario of the tab misalignment adjustment device; Figure 2 Schematic diagram of another application scenario of the tab misalignment adjustment device. The tab misalignment adjustment device of the present application includes a linkage mechanism 10, a side clamping mechanism 20 and a monitoring mechanism 30. The side clamping mechanism 20 is arranged on both sides of the linkage mechanism 10. The monitoring mechanism 30 is located above the linkage mechanism 10 so that it can be located above the pole group 50. The monitoring end of the monitoring mechanism 30 can be aligned with the tab area of ​​the pole group 50. The pole group 50 is taken out from the winding needle 40 of the winding device. The monitoring mechanism 30 monitors the tab area on the pole group 50. If there is a tab misalignment phenomenon in the tab area, the monitoring mechanism 30 will feed back the detected information, and then make the linkage mechanism 10 work. The linkage mechanism 10 and the side clamping mechanism 20 cooperate to drive the various layers of tabs in the tab area on the pole group 50 to align. When the monitoring mechanism 30 detects that the various layers of tabs in the tab area are aligned, the linkage mechanism 10 will stop working.

[0052] Refer to it again Figure 3-Figure 6 As shown, Figure 3 A schematic diagram of a partial structure of a tab misalignment adjustment device; Figure 4 is another schematic diagram of a partial structure of the tab misalignment adjustment device; Figure 5 Schematic diagram of the three-dimensional structure of the linkage mechanism 10; Figure 6FIG2 is another schematic diagram of the three-dimensional structure of the linkage mechanism 10. The linkage mechanism 10 includes a carrier 101, a drive assembly 102, a linear linkage assembly 103, a rotary linkage assembly 104, a first output roller 105, and a second output roller 106. The drive assembly 102 is disposed on the carrier 101, and the linear linkage assembly 103 and the rotary linkage assembly 104 are both connected to the drive assembly 102. The linear linkage assembly 103 and the rotary linkage assembly 104 are disposed on the same side of the carrier 101 and are distributed along the X-direction. The first output roller 105 and the second output roller 106 are spaced apart and parallel to each other. The first output roller 105 and the second output roller 106 are rotationally connected to the linear linkage assembly 103, and the first output roller 105 and the second output roller 106 are fixedly connected to the rotary linkage assembly 104. In another embodiment, the linear linkage assembly 103 is connected to the drive assembly 102, and the rotary linkage assembly 104 is connected to the linear linkage assembly 103.

[0053] The side clamping mechanism 20 includes a first side clamping assembly 201 and a second side clamping assembly 202. The first side clamping assembly 201 and the second side clamping assembly 202 are both arranged on the carrier 101. The first side clamping assembly 201 is arranged on the side of the first output roller 105 away from the second output roller 106, and the second side clamping assembly 202 is arranged on the side of the second output roller 106 away from the first output roller 105. When working, the first side clamping assembly 201 cooperates with the first output roller 105 to clamp on one side of the pole group 50, and the second side clamping assembly 202 cooperates with the second output roller 106 to clamp on one side of the pole group 50. The two output rollers 106 cooperate to clamp the other side of the pole group 50; specifically, the first side clamping assembly 201 and the second side clamping assembly 202 are both located in the outer layer of the pole group 50, and the first output roller 105 and the second output roller 106 are located in the inner layer of the pole group 50; the above-mentioned "outer layer" refers to the outermost layer after the pole group 50 is wound, and the outer layer located at the pole group 50 means that it can abut against the outer layer of the pole group 50; the "inner layer" refers to the innermost layer after the pole group 50 is wound, and the inner layer located at the pole group 50 means that it can abut against the inner layer of the pole group 50.

[0054] Please review Figure 5 and Figure 6 The driving component 102 is used to drive the linear linkage component 103 and the rotary linkage component 104 to move synchronously. At this time, the first output roller 105 and the second output roller 106 can move linearly under the action of the linear linkage component 103, and the rotary linkage component 104 can drive the first output roller 105 and the second output roller 106 to rotate.

[0055] Refer to it again Figure 7 As shown, Figure 7Figure 1 is a schematic diagram of the three-dimensional structure of the drive assembly 102. The drive assembly 102 includes a drive member 1021, a transmission assembly 1022, and a mounting frame 1023. The drive member 1021 is disposed on one side of the carrier 101. The transmission assembly 1022 is connected to the output shaft 10211 of the drive member 1021 and the mounting frame 1023, respectively. The mounting frame 1023 is connected to the linear linkage assembly 103 and the rotary linkage assembly 104. When the drive member 1021 is in operation, the output shaft 10211 of the drive member 1021 drives the transmission assembly 1022 to move, which in turn drives the mounting frame 1023 to move relative to the carrier 101. Finally, the mounting frame 1023 drives the linear linkage assembly 103 and the rotary linkage assembly 104 to move accordingly. Specifically, the drive member 1021 is a motor.

[0056] The transmission assembly 1022 includes a screw rod 10221 and a slider 10222. The screw rod 10221 is connected to the output shaft 10211 of the driving member 1021. The slider 10222 is screwed to the screw rod 10221. The mounting frame 1023 is set on the slider 10222. When the driving member 1021 is working, the output shaft 10211 of the driving member 1021 drives the screw rod 10221 to rotate, thereby driving the slider 10222 to move on the screw rod 10221. Finally, it drives the carrying frame 1023 to move; in specific applications, the two ends of the screw rod 10221 are respectively rotatably connected to the bearing seats 10223, and the two bearing seats 10223 are fixedly set on the carrier 101. The screw rod 10221 can rotate relative to the bearing seats 10223 without linear movement; in addition, the slider 10222 is connected to the carrying frame 1023 through two rod bodies 10224, and the two rod bodies 10224 are distributed on both sides of the slider 10222.

[0057] The mounting frame 1023 includes a first mounting plate 10231, a second mounting plate 10232, and a connecting rod 10233. The first mounting plate 10231 connects the two rods 10224 and the linear linkage assembly 103. The second mounting plate 10232 is spaced apart from the first mounting plate 10231. The connecting rod 10233 connects the first mounting plate 10231 and the second mounting plate 10232 at both ends. The second mounting plate 10232 is connected to the rotational linkage assembly 104. During use, the slider 10222 drives the first mounting plate 10231 via the two rods 10224, which in turn drives the linear linkage assembly 103. Simultaneously, the first mounting plate 10231 drives the second mounting plate 10232 via the connecting rod 10233, which in turn drives the rotational linkage assembly 104. In this embodiment, there are two connecting rods 10233.

[0058] Refer to it again Figure 8 and Figure 9 As shown, Figure 8Schematic diagram of the three-dimensional structure of the linear linkage assembly 103; Figure 9 Figure 1 is a schematic diagram of the three-dimensional structure of the first linkage plate 1031. The linear linkage assembly 103 includes the first linkage plate 1031, the second linkage plate 1032, the third linkage plate 1033, and the fourth linkage plate 1034. The first linkage plate 1031 has two ends rotatably connected to the first end of the second linkage plate 1032 and the second end of the fourth linkage plate 1034, respectively. The third linkage plate 1033 has two ends rotatably connected to the second end of the second linkage plate 1032 and the first end of the fourth linkage plate 1034, respectively. Furthermore, the linear linkage assembly 103 also includes a first connecting shaft 1035, a second connecting shaft 1036, a third connecting shaft 1037 and a fourth connecting shaft 1038. The first end of the first linkage plate 1031 and the second end of the fourth linkage plate 1034 are rotatably connected via the first connecting shaft 1035, the second end of the first linkage plate 1031 and the first end of the second linkage plate 1032 are rotatably connected via the second connecting shaft 1036, the second end of the second linkage plate 1032 and the first end of the third linkage plate 1033 are rotatably connected via the third connecting shaft 1037, the second end of the third linkage plate 1033 and the first end of the fourth linkage plate 1034 are rotatably connected via the fourth connecting shaft 1038, the first output roller 105 is rotatably connected to the second connecting shaft 1036, and the second output roller 106 is rotatably connected to the fourth connecting shaft 1038. Specifically, one end of the first output roller 105 is passed through the second connecting shaft 1036 and can rotate relative to the second connecting shaft 1036, and one end of the second output roller 106 is passed through the fourth connecting shaft 1038 and can rotate relative to the fourth connecting shaft 1038; the first connecting shaft 1035 is set on the first carrying plate 10231. When the first carrying plate 10231 moves, the first linkage plate 1031 and the fourth linkage plate 1034 will be driven to move through the first connecting shaft 1035.

[0059] Furthermore, both ends of the first linkage plate 1031 and the third linkage plate 1033 are provided with avoidance grooves 10311. Both ends of the second linkage plate 1032 and both ends of the fourth linkage plate 1034 are located within the avoidance grooves 10311, thereby providing space for the second linkage plate 1032 and the fourth linkage plate 1034 to rotate. The first connecting shaft 1035 passes through the two sidewalls of the avoidance groove 10311 at the first end of the first linkage plate 1031. The second end of the fourth linkage plate 1034 is sleeved on the outer surface of the first connecting shaft 1035. Both the first linkage plate 1031 and the fourth linkage plate 1034 can rotate relative to the first connecting shaft 1035. Similarly, the second connecting shaft 1036, the third connecting shaft 1037, and the fourth connecting shaft 1038 are all arranged in the same manner and will not be further described here. It should also be noted that the avoidance groove 10311 can also be provided in the second linkage plate 1032 and the fourth linkage plate 1034, and is not limited to the first linkage plate 1031 and the third linkage plate 1033. In this embodiment, the shape formed by the first linkage plate 1031, the second linkage plate 1032, the third linkage plate 1033, and the fourth linkage plate 1034 after being connected is a quadrilateral.

[0060] The linear linkage assembly 103 further includes a guide rail 1039 and a first movable block 1030. The guide rail 1039 is disposed on the carrier 101. The first movable block 1030 is slidably mounted on the guide rail 1039. The first mounting plate 10231 is connected to the first movable block 1030 on a side away from the first connecting shaft 1035. When the first mounting plate 10231 moves, it simultaneously drives the first movable block 1030 and the first connecting shaft 1035 to move, causing the first movable block 1030 to perform linear motion along the guide rail 1039. The linear linkage assembly 103 further includes a second movable block 10310, which is slidably mounted on the guide rail 1039 and connected to the third connecting shaft 1037. When the first movable block 1030 moves, it drives the second movable block 10310 to move together via the first linkage plate 1031, the second linkage plate 1032, the third linkage plate 1033, and the fourth linkage plate 1034. The first movable block 1030 and the second movable block 10310 move toward or away from each other.

Specifically, the first side clamp driver 2012 is a pneumatic cylinder. The first side clamp driver 2012 drives the first side clamp transmission body 2013 to slide relative to the first side clamp fixing plate 2011. The first side clamp transmission body 2013 then drives the first mounting rod 2018 and the first side clamp roller 2014 to slide relative to the first side clamp fixing plate 2011, thereby increasing or decreasing the distance between the first side clamp roller 2014 and the first output roller 105, thereby clamping one side of the pole group 50 with the first side clamp roller 2014 and the first output roller 105.

[0069] Furthermore, in order to improve the stability of the movement process of the first side clamp transmission body 2013 and improve the carrying capacity of the first side clamp transmission body 2013, the first side clamp assembly 201 also includes a first slide bar 2015 and a first carrying block 2016.

Specifically, the second side clamp driver 2024 is a cylinder. The second side clamp driver 2024 drives the second side clamp transmission body 2025 to slide relative to the second side clamp fixing plate 2021. The second side clamp transmission body 2025 then drives the second mounting rod 2023 and the second side clamp roller 2022 to slide relative to the second side clamp fixing plate 2021, thereby increasing or decreasing the distance between the second side clamp roller 2022 and the second output roller 106, so that the second side clamp roller 2022 and the second output roller 106 clamp the other side of the pole group 50.

Specifically, the second bearing body 2028 is a conventional bearing structure.

[0074] Please review Figure 1 and Figure 2The monitoring mechanism 30 in this embodiment adopts an existing visual monitoring system, such as an industrial camera CCD that cooperates with a control system. The industrial camera CCD serves as the monitoring end of the monitoring mechanism 30. The industrial camera CCD is in communication with the control system, and the control system is in communication with the power member 1041 of the rotating linkage assembly 104. The industrial camera CCD performs tab misalignment detection on the tab area of ​​the pole group 50 after winding is completed and taken out and leveled, and feeds back the tab misalignment information to the control system. The control system determines the direction of adjustment required, and then the control system issues a command to rotate the power member 1041 in the corresponding direction, thereby causing the first output roller 105 and the second output roller 106 to rotate in the corresponding direction. During this rotation adjustment process, the industrial camera CCD will continue to monitor the tab area. After the tabs of each layer in the tab area are aligned, the control system will issue a command to stop the power member 1041.

[0075] Preferably, the tab misalignment adjustment device also includes a power body (not marked in the figure), the output end of the power body is connected to the carrier 101, and the power body drives the carrier 101 to move relative to the winding needle 40, and the carrier 101 drives the driving component 102, linear linkage component 103, rotary linkage component 104, first output roller 105, second output roller 106 and side clamping mechanism 20 arranged thereon to move together, thereby realizing the function of removing the pole group 50 from the winding needle 40, so as to facilitate the subsequent adjustment of the tab misalignment of the pole group 50.

[0076] When the tab misalignment adjustment device is working, the power body drives the carrier 101 to move toward the winding needle 40, and the first output roller 105, the second output roller 106, the first side clamping roller 2014 and the second side clamping roller 2022 respectively reach the corresponding positions, and the driving member 1021 and / or the side clamping driving body work, so that the first output roller 105 and the first side clamping roller 2014 are clamped on one side of the pole group 50, and the second output roller 106 and the second side clamping roller 2022 are clamped on the other side of the pole group 50, and then the power body drives the carrier 101 to move toward the initial position. At this time, it is the process of removing the pole group 50 from the winding needle 40. The driving member 1021 works further, causing the first output roller 105 and the second output roller 106 to move away from each other. At the same time, the side clamping driving body works further, and the first side clamping roller 2014 and the second side clamping roller 2022 also move away from each other, thereby flattening the pole group 50 toward both sides. Subsequently, the monitoring mechanism 30 detects the misalignment direction of the pole ear of the pole group 50 and issues a command to cause the power member 1041 to rotate in the specified direction, thereby driving the first output roller 105 and the second output roller 106 to move in the specified direction. The first output roller 105 and the first side clamping roller 2014 act on the inner and outer layers of the electrode assembly 50, respectively. At the same time, the friction forces generated by the first output roller 105 and the first side clamping roller 2014 on the electrode assembly 50 are in opposite directions. Similarly, the second output roller 106 and the second side clamping roller 2022 use the same action mode, ultimately achieving the effect of adjusting the tab misalignment of the electrode assembly 50. After the monitoring mechanism 30 recognizes that the tabs of each layer in the tab area have been aligned, the operation of the power member 1041 is stopped. Finally, the driving member 1021 and / or the side clamping driving body can be activated again, so that the first output roller 105 and the first side clamping roller 2014 no longer clamp the electrode assembly 50. Similarly, the second output roller 106 and the second side clamping roller 2022 no longer clamp the electrode assembly 50, and the electrode assembly 50 can be removed; or it can be transported to the next station in the current state.

[0077] To sum up, after the electrode group is wound and taken out, the first output roller, the second output roller, the first side clamping assembly and the second side clamping assembly cooperate to clamp the two sides of the electrode group respectively, and flatten the electrode group toward both sides; the monitoring mechanism monitors the electrode ear area of ​​the electrode group. If the electrode ear misalignment is found in the electrode ear area, the monitoring mechanism issues an instruction to make the rotary linkage assembly work, and the rotary linkage assembly drives the first output roller and the second output roller to rotate in the specified direction, and cooperates with the first side clamping assembly and the second side clamping assembly to act on the electrode group, so that the electrode ears of each layer of the electrode group move relative to each other, and finally the misalignment adjustment of the electrode ears is achieved. After the monitoring mechanism recognizes that the electrode ears are adjusted in place, the operation of the rotary linkage assembly is stopped; the electrode ear misalignment monitoring and adjustment of the electrode group after winding is completed and taken out and flattened can reduce the monitoring accuracy requirements, making it easier to monitor the actual misalignment of the electrode ears, and the monitoring mechanism adjusts the electrode ear misalignment while monitoring, and solves the hysteresis problem caused by the electrode ear misalignment adjustment during the winding process, and finally achieves high-precision adjustment of the electrode ear misalignment and reduces the probability of electrode group defects.

[0078] Example 2

[0079] This embodiment provides a tab misalignment adjustment method, wherein the method can be implemented by the tab misalignment adjustment device in the first embodiment. The specific steps of the tab misalignment adjustment method are as follows:

[0080] Step S1: Removing and leveling the electrode assembly 50. After the electrode assembly 50 is wound on the winding needle 40, it is removed from the winding needle 40. The linear linkage assembly 103 drives the first output roller 105 and the second output roller 106 to move linearly away from each other, leveling the electrode assembly 50 toward both sides. At this time, the first output roller 105 and the first side clamp assembly 201 clamp one side of the electrode assembly 50, while the second output roller 106 and the second side clamp assembly 202 clamp the other side of the electrode assembly 50.

[0081] In specific application, after the electrode group 50 is wound on the winding needle 40, the power body can be used to drive the carrier 101 to move toward the direction close to the electrode group 50, and then the first output roller 105 and the second output roller 106 are inserted into the avoidance hole inside the winding needle 40, so that the first output roller 105 and the second output roller 106 are placed in the inner layer of the electrode group 50, and the first side clamping roller 2014 and the second side clamping roller 2022 are placed in the outer layer of the electrode group 50; the linear linkage component 103 drives the first output roller 105 and the second output roller 106 to move a distance away from each other. At this time, the first output roller 105, the second output roller 106, the first side clamping roller 2014 and the second side clamping roller 2022 jointly clamp the two sides of the electrode group 50, and through the power body Driven by the force body, the pole group 50 is taken out from the winding needle 40, and then the linear linkage component 103 continues to drive the first output roller 105 and the second output roller 106 to move away from each other, and in coordination with it, the first side clamping driving body 2012 drives the first side clamping roller 2014 to move in the direction away from the second side clamping roller 2022, and the first output roller 105 and the first side clamping roller 2014 maintain a clamping state on one side of the pole group 50; similarly, the second side clamping driving body 2024 drives the second side clamping roller 2022 to move in the direction away from the first side clamping roller 2014, and the second output roller 106 and the second side clamping roller 2022 maintain a clamping state on the other side of the pole group 50; the above process realizes the flattening of the pole group 50.

[0082] In addition, the pole group 50 can be first removed from the winding needle 40 through other devices, and then the first output roller 105 and the second output roller 106 are inserted into the inner layer of the pole group 50. At this time, the first side clamping roller 2014 and the second side clamping roller 2022 are respectively located in the outer layer of the pole group 50, and correspond to the first output roller 105 and the second output roller 106 respectively. Then the linear linkage component 103 drives the first output roller 105 and the second output roller 106 to move away from each other until the pole group 50 is flattened. At this time, the first output roller 105 and the first side clamping roller 2014 cooperate to clamp one side of the pole group 50, and the second output roller 106 and the second side clamping roller 2022 cooperate to clamp the other side of the pole group 50.

[0083] Step S2: Tab misalignment information collection. The monitoring mechanism 30 monitors the tab misalignment direction of the tab region of the electrode assembly 50 (i.e., collects information on the tab misalignment direction). Based on this information, it issues a command to rotate the rotary linkage assembly 104 in the corresponding direction. Specifically, the rotary linkage assembly 104 operates and drives the first output roller 105 and the second output roller 106 to rotate in a specified direction, such as clockwise or counterclockwise, depending on the tab misalignment direction. Finally, the first side clamping roller 2014 and the second side clamping roller 2022 are used to adjust the tab misalignment.

[0084] In specific applications, in addition to collecting the tab misalignment direction information in the initial state, the monitoring mechanism 30 also collects the tab misalignment amount information, and issues instructions based on the tab misalignment direction information and the tab misalignment amount information, rotating the linkage assembly 104 to work, and driving the first output roller 105 and the second output roller 106 to rotate in the corresponding direction to the required angle, thereby adjusting the tab misalignment.

[0085] Further explanation: after receiving the instruction, the rotating linkage component 104 drives the first output roller 105 and the second output roller 106 to rotate in the specified direction, and drives the pole group 50 to rotate in the same direction. At this time, the first side clamping roller 2014 and the second side clamping roller 2022 rotate in the opposite direction of the first output roller 105 and the second output roller 106. In this process, the direction of the friction force applied by the first output roller 105 and the second output roller 106 to the inner layer of the pole group 50 is opposite to the direction of the friction force applied by the first side clamping roller 2014 and the second side clamping roller 2022 to the outer layer of the pole group 50, thereby achieving adjustment of the pole ear misalignment of the pole group 50.

[0086] It should also be noted that the monitoring mechanism 30 can collect the tab misalignment information of the electrode group 50 in a continuous or intermittent manner. That is, the monitoring mechanism 30 can continuously collect the tab misalignment information, or collect the tab misalignment information at one or more designated times, so that the monitoring mechanism 30 can promptly determine whether the tab is properly adjusted.

[0087] Step S3: Tab misalignment adjustment is complete. When the tab misalignment value collected by the monitoring mechanism 30 meets the requirements, the tab misalignment is determined to have been adjusted. At this point, the monitoring mechanism 30 issues a command to stop the rotation linkage assembly 104, i.e., no further adjustment is made to the electrode assembly 50, and the electrode assembly 50 can be transported to the next workstation. If the tab misalignment value collected by the monitoring mechanism 30 still does not meet the requirements, the electrode assembly 50 is determined to be defective.

[0088] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
