Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing equipment technology, and more specifically, to an electrode welding machine. Background Technology

[0002] In existing technologies, conductive foil and aluminized film are welded together using an electrode welding machine, which can improve the safety and electrical performance of batteries. As power batteries iterate towards higher energy density and larger sizes, the requirements for wide-width composite electrodes are becoming increasingly stringent. Wide-width composite electrodes, due to the interlacing of multiple layers of foil and coating areas, require significantly higher precision in double-sided welding and stricter thermal control. However, existing electrode welding mechanisms typically only perform single-sided welding, which is prone to uneven stress leading to electrode delamination, incomplete welds, or localized thermal damage, affecting the welding quality and making them unsuitable for welding wide-width electrodes. Utility Model Content

[0003] The present invention aims to solve the above-mentioned defects of existing materials and provide an electrode welding mechanism that can perform double-sided welding, has better compatibility with electrode width, and has a wider range of applications.

[0004] To solve the above problems, this utility model provides an electrode welding machine, comprising:

[0005] Aluminized film unwinding mechanism, used for unwinding aluminized film;

[0006] A foil unwinding mechanism includes a first foil unwinding mechanism, a second foil unwinding mechanism, a third foil unwinding mechanism, and a fourth foil unwinding mechanism. The first foil unwinding mechanism and the third foil unwinding mechanism are respectively used to unwind a first aluminum foil and a third aluminum foil, such that the first aluminum foil is located on the upper layer of the first side of the aluminized film, and the third aluminum foil is located on the lower layer of the first side of the aluminized film. The second foil unwinding mechanism and the fourth foil unwinding mechanism are respectively used to unwind a second aluminum foil and a fourth aluminum foil, such that the second aluminum foil is located on the upper layer of the second side of the aluminized film, and the fourth aluminum foil is located on the lower layer of the second side of the aluminized film. The first side and the second side are two sides of the aluminized film that are arranged opposite each other along the width direction.

[0007] A welding mechanism is used to weld at least one of the stacked first aluminum foil and the third aluminum foil to the aluminized film, and / or to weld at least one of the stacked second aluminum foil and the fourth aluminum foil to the aluminized film to form a finished strip;

[0008] A smoothing mechanism is used to flatten the burrs on the finished strip after welding;

[0009] A finished strip winding mechanism is used to collect the finished strip into a roll.

[0010] Furthermore, the welding mechanism includes a first welding component, a second welding component, and a support base. The first welding component and the second welding component are both disposed on the support base. The first welding component and the second welding component are disposed opposite to each other along the width direction of the aluminum-plated film, and the first welding component can move along the width direction of the aluminum-plated film, so that the first welding component is closer to the second welding component or away from the second welding component.

[0011] Furthermore, both the first welding assembly and the second welding assembly include an active welding head, a driven welding head, and a lifting drive. The active welding head and the driven welding head are arranged opposite each other along the thickness direction of the aluminum-coated film. The lifting drive is connected to the active welding head, and the lifting welding head is used to drive the active welding head to move closer to or away from the driven welding head.

[0012] Furthermore, it also includes a composite pressure roller, which is disposed before the welding mechanism. The composite pressure roller is used to pre-press at least one of the stacked first aluminum foil and the third aluminum foil with the aluminized film, or the composite pressure roller is used to pre-press at least one of the stacked second aluminum foil and the fourth aluminum foil with the aluminized film.

[0013] Furthermore, the first foil unwinding mechanism and the third foil unwinding mechanism are located on the first side of the width direction of the aluminized film, and the second foil unwinding mechanism and the fourth foil unwinding mechanism are located on the second side of the width direction of the aluminized film, and the first foil unwinding mechanism and the third foil unwinding mechanism can move along the width direction of the aluminized film.

[0014] Furthermore, the first foil unwinding mechanism, the second foil unwinding mechanism, the third foil unwinding mechanism, and the fourth foil unwinding mechanism each include an aluminum foil unwinding assembly, an aluminum foil tension adjusting component, an aluminum foil dust removal assembly, an aluminum foil splicing assembly, and an aluminum foil correction assembly arranged sequentially along the conveying direction of each aluminum foil. The aluminum foil correction assembly is used to correct the deviation of the aluminum foil conveyed to the welding mechanism.

[0015] Furthermore, the aluminum foil buffer assembly includes a tension roller, a tension sensor, and a tension swing arm roller. The tension roller is connected to the tension sensor, which is used to detect the tension of the aluminum foil during the conveying process. The tension swing arm roller is used to adjust the tension of the aluminum foil during the conveying process.

[0016] Furthermore, an aluminum-coated film unwinding mechanism, an aluminum-coated film dust removal mechanism, an aluminum-coated film traction mechanism, an aluminum-coated film tension adjustment mechanism, and an aluminum-coated film correction mechanism are sequentially arranged between the aluminum-coated film unwinding mechanism and the welding mechanism. The aluminum-coated film correction mechanism is used to correct the aluminum-coated film conveyed to the welding mechanism.

[0017] Furthermore, it also includes a visual inspection mechanism and a defective product marking mechanism. Along the conveying direction of the finished product belt, the visual inspection mechanism is located after the smoothing mechanism, and the defective product marking mechanism is located after the visual inspection mechanism. The defective product marking mechanism is used to mark unqualified finished product belts according to the inspection results of the visual inspection mechanism.

[0018] Furthermore, it also includes a dust removal mechanism, which includes multiple dust removal pipes, each of which is connected to the aluminum foil dust removal assembly and the aluminized film dust removal assembly.

[0019] The electrode welding machine of this invention, by unwinding aluminum foil onto both sides of the aluminum-coated film in the width direction, and placing a layer of aluminum foil on both the top and bottom sides of the aluminum-coated film, allows the welding mechanism to simultaneously weld both sides of the aluminum-coated film in the width direction. This ensures that at least one of the two layers of aluminum foil is welded together with the aluminum-coated film. This not only solves the problems of electrode delamination, incomplete welding, or localized thermal damage caused by the inability to simultaneously weld both sides of the electrode in existing technologies using single-sided or segmented welding, but also allows the electrode welding machine to meet the requirement of simultaneous welding on both sides, improve the welding quality of wide electrodes, and increase the welding efficiency of wide electrodes. Furthermore, the welding mechanism can also weld only one side of the aluminum-coated film in the width direction, thus meeting the single-sided welding requirement and welding narrow electrodes. This electrode welding mechanism has better compatibility with electrode widths and is applicable to various welding situations, expanding the applicability of the electrode welding machine.

[0028] Combination Figures 1 to 3 As shown, the first aspect of this embodiment provides an electrode welding machine, including: a frame, and an aluminized film unwinding mechanism 1, a foil unwinding mechanism, a welding mechanism 6, a smoothing mechanism 7, a splicing platform 8, and a finished product winding mechanism 9 disposed on the frame, wherein:

[0029] The aluminized film unwinding mechanism 1 is used to unwind the aluminized film 100;

[0030] The foil unwinding mechanism includes a first foil unwinding mechanism 2, a second foil unwinding mechanism 3, a third foil unwinding mechanism 4, and a fourth foil unwinding mechanism 5. The first foil unwinding mechanism 2 and the third foil unwinding mechanism 4 can be located in the width direction of the aluminized film 100 (i.e., Figure 3 The first side (in the y-axis direction) Figure 3In area A of the film, the first foil unwinding mechanism 2 and the third foil unwinding mechanism 4 are used to unwind the first aluminum foil 110 and the third aluminum foil 130, respectively, so that the first aluminum foil 110 is located on the upper layer of the first side of the aluminized film 100, and the third aluminum foil 130 is located on the lower layer of the first side of the aluminized film 100; the second foil unwinding mechanism 3 and the fourth foil unwinding mechanism 5 can be located on the second side of the width direction of the aluminized film 100. Figure 3 In area B of the film, the second foil unwinding mechanism 3 and the fourth foil unwinding mechanism 5 are used to unwind the second aluminum foil 120 and the fourth aluminum foil 140, respectively. The second aluminum foil 120 is located on the upper layer of the second side of the aluminized film 100, and the fourth aluminum foil 140 is located on the lower layer of the second side of the aluminized film 100. The first side and the second side are two sides of the aluminized film 100 that are arranged opposite to each other along the width direction.

[0031] The welding mechanism 6 is used to weld at least one of the stacked first aluminum foil 110 and third aluminum foil 130 to the aluminized film 100, and / or to weld at least one of the stacked second aluminum foil 120 and fourth aluminum foil 140 to the aluminized film 100 to form a finished strip 150; that is, the welding mechanism 6 can weld only the first aluminum foil 110 and third aluminum foil 130 located on the first side of the aluminized film 100. During welding, it can weld only the stacked first aluminum foil 110 and the aluminized film 100, or only the stacked third aluminum foil 130 and the aluminized film 100, or the stacked first aluminum foil 110, the aluminized film 100 and... The third aluminum foil 130 is welded; the welding mechanism 6 can weld only the second aluminum foil 120 and the fourth aluminum foil 140 located on the second side of the aluminized film 100. During welding, only the stacked second aluminum foil 120 and the aluminized film 100 can be welded, or only the stacked fourth aluminum foil 140 and the aluminized film 100 can be welded, or the stacked second aluminum foil 120, the aluminized film 100 and the fourth aluminum foil 140 can be welded. The welding mechanism 6 can also weld the first aluminum foil 110 and the third aluminum foil 130 located on the first side of the aluminized film 100, as well as the second aluminum foil 120 and the fourth aluminum foil 140 located on the first side of the aluminized film 100, simultaneously.

[0032] The smoothing mechanism 7 is used to flatten the burrs on the finished strip 150 after welding;

[0033] The splicing platform 8 is used to join broken finished strips 150;

[0034] The finished strip winding mechanism 9 is used to collect the finished strip 150 into a roll.

[0035] The electrode welding machine provided in this embodiment, by unwinding aluminum foil onto both sides of the aluminum-coated film in the width direction, and by placing a layer of aluminum foil on both the top and bottom sides of the aluminum-coated film, and by simultaneously welding both sides of the aluminum-coated film in the width direction, ensures that at least one of the two layers of aluminum foil is welded together with the aluminum-coated film. This not only solves the problems of electrode delamination, incomplete welding, or localized thermal damage caused by the inability to simultaneously weld both sides of the electrode in the prior art using single-sided welding or segmented welding, but also allows the electrode welding machine to meet the requirement of simultaneous welding on both sides, improve the welding quality of wide electrodes, and increase the welding efficiency of wide electrodes. In addition, the welding mechanism can also weld only one side of the aluminum-coated film in the width direction, which can also meet the single-sided welding requirement and weld narrow electrodes. This electrode welding mechanism has better compatibility with electrode width and can be applied to various welding situations, thus improving the applicability of the electrode welding machine.

[0036] Based on the above embodiments, as an optional implementation method, combined with Figure 4 As shown, the welding mechanism 6 includes a first welding component 61, a second welding component 62, and a support base 63. Both the first welding component 61 and the second welding component 62 are mounted on the support base 63. The first welding component 61 and the second welding component 62 are arranged opposite each other along the width direction of the aluminized film 100. The first welding component 61 can move along the width direction of the aluminized film 100, moving closer to or away from the second welding component 62, thereby adjusting the distance between the first welding component 61 and the second welding component 62. This allows the welding mechanism 6 to weld electrodes of different widths. Specifically, the support base 63 and the first welding component 61 can be connected by a slide rail and a slider. The slide rail is arranged along the width direction of the aluminized film 100, and the slider is located at the bottom of the first welding component 61, enabling the first welding component 61 to move along the width direction of the aluminized film 100. The second welding component 62 can be fixedly mounted on the support base 63.

[0037] Based on the above embodiments, as an optional implementation, the first welding assembly 61 and the second welding assembly 62 have the same structure. The structure of the welding assembly will be described below using the first welding assembly 61 as an example. (Combined with...) Figure 5As shown, the first welding assembly 61 includes an active welding head 611, a driven welding head 612, and a lifting drive 613. The active welding head 611 and the driven welding head 612 are arranged opposite each other along the thickness direction of the aluminized film 100. The lifting drive 613 is connected to the active welding head 611 and is used to drive the active welding head 611 to move closer to or away from the driven welding head 612. Thus, when welding the aluminized film 100 and the aluminum foil is required, the active welding head 611 moves closer to the driven welding head 612 and contacts the aluminized film 100 and the aluminum foil, welding the aluminized film 100 and the aluminum foil through rolling welding. After welding is completed, the active welding head 611 moves away from the driven welding head 612. The lifting drive 613 can be a motor or a cylinder. In this embodiment, rolling welding not only has a fast welding speed, high welding head strength, good density, and no porosity, but also a good welding effect, and can weld ultra-thin strips.

[0038] Based on the above embodiments, as an optional implementation, the electrode welding machine further includes a composite pressure roller 10. The composite pressure roller 10 is disposed before the welding mechanism 6. The composite pressure roller 10 is used to pre-press at least one of the stacked first aluminum foil 110 and third aluminum foil 130 with the aluminized film 100, or the composite pressure roller 10 is used to pre-press at least one of the stacked second aluminum foil 120 and fourth aluminum foil 140 with the aluminized film 100. Thus, before the aluminum foil and aluminized film 100 enter the welding mechanism 6, the composite pressure roller 10 pre-presses the aluminum foil and aluminized film 100, which can prevent the aluminized film 100 and the aluminum foil disposed on the upper and lower layers of the aluminized film 100 from shifting, which is beneficial to improving the alignment of the aluminized film 100 and the aluminum foil disposed on the upper and lower layers of the aluminized film 100, and improving the welding quality of the electrode. Specifically, the composite pressure roller 10 includes a first pressure roller and a second pressure roller arranged opposite to each other along the thickness direction of the aluminized film 100. There is a gap between the first pressure roller and the second pressure roller that allows the aluminized film 100 and aluminum foil to pass through. The first pressure roller can move along the thickness direction of the aluminized film 100, so that the first pressure roller is close to or away from the second pressure roller.

[0039] Based on the above embodiments, as an optional implementation, the first foil unwinding mechanism 2 and the third foil unwinding mechanism 4 can move along the width direction of the aluminized film 100. Therefore, by setting the first foil unwinding mechanism 2 and the third foil unwinding mechanism 4 to move along the width direction of the aluminized film 100, the aluminum foil disposed on the first side of the width direction of the aluminized film 100 can adapt to the width of the aluminized film 100, thereby enabling compatibility with aluminized films 100 of different widths and adaptability to electrode sheets of different widths. Specifically, the first foil unwinding mechanism 2 and the third foil unwinding mechanism 4 can be connected to the frame via sliding blocks, enabling the first foil unwinding mechanism 2 and the third foil unwinding mechanism 4 to move along the width direction of the aluminized film 100.

[0040] The first foil unwinding mechanism 2, the second foil unwinding mechanism 3, the third foil unwinding mechanism 4, and the fourth foil unwinding mechanism 5 are all used for unwinding aluminum foil. The structures of the first foil unwinding mechanism 2, the second foil unwinding mechanism 3, the third foil unwinding mechanism 4, and the fourth foil unwinding mechanism 5 are basically the same. The only difference is that these foil unwinding mechanisms are used to unwind different aluminum foils. The following explanation of the foil unwinding mechanism will be based on the first foil unwinding mechanism 2 as an example.

[0041] Combination Figure 6 As shown, the first foil unwinding mechanism 2 includes an aluminum foil unwinding assembly 21, an aluminum foil tension adjusting component 22, an aluminum foil dust removal assembly 23, an aluminum foil splicing assembly 24, and an aluminum foil deviation correction assembly 25 arranged sequentially along the conveying direction of the first aluminum foil 110. The aluminum foil unwinding assembly 21 is used to install the aluminum foil roll to be welded. The aluminum foil tension adjusting component 22 is used to adjust the tension of the aluminum foil during the conveying process to keep the tension of the aluminum foil stable during the conveying process. The aluminum foil dust removal assembly 23 removes dust from the aluminum foil during the conveying process with a brush to ensure that the aluminum foil is dust-free on both sides during welding. The aluminum foil splicing assembly 24 is used to join the aluminum foil. The aluminum foil deviation correction assembly 25 is used to correct the deviation of the aluminum foil conveyed to the welding mechanism 6. As an optional implementation, the aluminum foil tension adjusting component 22 includes a tension roller 221, a tension sensor 222, and a tension swing arm roller 223. The aluminum foil output from the aluminum foil unwinding assembly 21 is conveyed to the tension roller 221 after passing through the tension swing arm roller 223. The tension roller 221 is connected to the tension sensor 222, which detects the tension of the aluminum foil during the conveying process. The tension swing arm roller 223 adjusts the tension of the aluminum foil during the conveying process through circular motion, thereby adjusting the tension of the conveyor belt and maintaining a relatively low tension on the aluminum foil during conveying. Furthermore, the alternating arrangement of the tension swing arm roller and the other rollers acts as a buffer, storing the aluminum foil during the conveying process, which helps to increase the running speed of the aluminum foil. In this embodiment, by individually correcting the aluminum foil before it enters the welding mechanism 6, the accuracy of the aluminum foil's position during welding can be improved, which is beneficial for improving the alignment between the aluminum foil and the aluminized film 100 and improving the welding quality.

[0042] In this embodiment, the aluminum foil unwinding assembly 21, aluminum foil dust removal assembly 23, aluminum foil splicing assembly 24, and aluminum foil alignment assembly 25 all adopt conventional unwinding, dust removal, splicing, and alignment assemblies from existing electrode manufacturing equipment. The structure of these assemblies is not modified in this embodiment and will not be described in detail here. The structures of the second foil unwinding mechanism 3, the third foil unwinding mechanism 4, and the fourth foil unwinding mechanism 5 are described in the same manner as the first foil unwinding mechanism 2, and will not be repeated here.

[0043] Based on the above embodiments, as an optional implementation, the electrode welding machine further includes an aluminized film attaching assembly 11, an aluminized film dust removal assembly 12, an aluminized film traction mechanism 13, an aluminized film tension adjustment mechanism 14, and an aluminized film correction mechanism 15. The aluminized film attaching assembly 11, the aluminized film dust removal assembly 12, the aluminized film traction mechanism 13, the aluminized film tension adjustment mechanism 14, and the aluminized film correction mechanism 15 are arranged sequentially along the conveying direction of the aluminized film 100. The aluminized film attaching assembly 11 is located after the aluminized film unwinding mechanism 1, and the aluminized film correction mechanism 15 is located before the aluminized film correction mechanism 15. The aluminized film splicing assembly 11 is used to join the aluminized film 100. The aluminized film dust removal assembly 12 removes dust from the aluminized film 100 during the conveying process using a brush, ensuring that both sides of the aluminized film 100 are dust-free during welding. The aluminized film traction mechanism 13 is used to pull the aluminized film 100, allowing it to be continuously output from the aluminized film unwinding mechanism 1. The aluminized film tension adjustment mechanism 14 is used to adjust the tension of the aluminized film 100 during the conveying process, ensuring that the tension of the aluminized film 100 remains stable during conveying. The aluminized film correction mechanism 15 is used to correct the deviation of the aluminized film 100 conveyed to the welding mechanism 6. In this embodiment, by correcting the deviation of the aluminized film 100 separately before it enters the welding mechanism 6, the accuracy of the position of the aluminized film 100 during welding can be improved, which is beneficial to improving the alignment between the aluminized film 100 and the aluminum foil, and thus improving the welding quality.

[0044] In this embodiment, the aluminized film splicing assembly 11, the aluminized film dust removal assembly 12, the aluminized film traction mechanism 13, the aluminized film tension adjustment mechanism 14, and the aluminized film correction mechanism 15 all adopt conventional splicing assemblies, dust removal assemblies, traction mechanisms, tension adjustment mechanisms, and correction mechanisms on existing electrode manufacturing equipment. In this embodiment, the structure of the above-mentioned components is not improved, and will not be described in detail here.

[0045] Based on the above embodiments, as an optional implementation, the smoothing mechanism 7 is arranged after the welding mechanism 6. The smoothing mechanism 7 is used to flatten the burrs on the finished strip 150 after welding, so that the finished strip 150 remains flat after welding and ensures that the thickness of the finished strip 150 after welding is uniform. At the same time, during the process of kneading the finished strip 150, the smoothing mechanism 7 can also flatten the burrs and rough edges, which is beneficial to improving the yield of the finished strip 150 and thus improving the quality of the battery.

[0046] Based on the above embodiments, as an optional implementation, the electrode welding machine further includes a vision inspection mechanism 16 and a defective product marking mechanism 17. Along the conveying direction of the finished product strip 150, the vision inspection mechanism 16 is positioned after the smoothing mechanism 7. The vision inspection mechanism 16 is used to detect whether the finished product strip 150 is qualified, for example, whether the aluminum foil and the aluminized film 100 are aligned. The vision inspection mechanism 16 can use optical detection methods or other detection methods to inspect the finished product strip 150. In this embodiment, the vision inspection mechanism 16 can be a CCD camera. The defective product marking mechanism 17 is positioned after the vision inspection mechanism 16. The defective product marking mechanism 17 is used to mark unqualified finished product strips 150 according to the detection results of the vision inspection mechanism 16. The defective product marking mechanism 17 can be a labeling machine.

[0047] Based on the above embodiments, as an optional implementation, a finished product belt tension adjusting component 18 is further provided between the welding mechanism 6 and the smoothing mechanism 7, and between the smoothing mechanism 7 and the visual inspection mechanism 16. The finished product belt tension adjusting component 18 is used to adjust the tension of the finished product belt 150 during the conveying process, so that the finished product belt 150 maintains stable tension during the conveying process. In this embodiment, by providing tension adjusting components before and after welding, and by blocking the tension of different segments through the traction mechanism, not only is the adjustment range large, but the tension of materials such as aluminum foil, aluminized film 100, and finished product belt 150 can also be maintained within a small range, achieving near-zero tension adjustment.

[0048] Based on the above embodiments, as an optional implementation, a finished product belt traction mechanism 19 and a finished product belt dust removal assembly 20 are sequentially arranged after the defective product marking mechanism 17 and before the belt receiving platform 8. The finished product belt traction mechanism 19 is used to traction the finished product belt 150, continuously conveying it to the finished product belt winding mechanism 9. The finished product belt dust removal assembly 20 uses brushes to remove dust from the finished product belt 150 during the conveying process, ensuring that both sides of the finished product belt 150 are dust-free before winding. In this embodiment, both the finished product belt traction mechanism 19 and the finished product belt dust removal assembly 20 are conventional traction mechanisms and dust removal assemblies used in existing electrode manufacturing equipment. The structure of these components is not improved in this embodiment and will not be described in detail here.

[0049] In this embodiment, the splicing platform 8 is used to splice the finished product belt 150 that has broken due to various abnormalities. The abnormally broken finished product belt 150 can be spliced ​​manually at the splicing platform 8, or it can be spliced ​​by a conventional splicing mechanism in the art.

[0050] Based on the above embodiments, as an optional implementation, the electrode welding machine further includes a dust removal mechanism 21. The dust removal mechanism 21 is located at the rear of the frame and includes multiple dust removal pipes. Each dust removal pipe is connected to a different aluminum foil dust removal assembly (such as aluminum foil dust removal assembly 23), an aluminized film dust removal assembly 12, and a finished product belt dust removal assembly 20. Through each dust removal pipe, functions such as negative pressure detection, differential pressure detection, and airflow control can be achieved for each dust removal assembly to ensure the dust removal effect of the finished product belt 150 and improve its quality. In this embodiment, negative pressure detectors, differential pressure detectors, and airflow controllers can be installed on each dust removal pipe to achieve the corresponding functions. In this embodiment, the negative pressure detectors, differential pressure detectors, and airflow controllers are all conventional negative pressure detectors, differential pressure detectors, and airflow controllers used in existing electrode manufacturing equipment. The structure of these components is not improved in this embodiment and will not be described in detail here.

[0051] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
