Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to a composite current collector roll welding forming equipment. Background Technology
[0002] With the development of new energy vehicles and energy storage, the requirements for battery cost, lifespan, and high energy density are becoming increasingly stringent, leading to larger and larger battery sizes. For example... Figure 3 and Figure 4 As shown, the positive / negative electrode roll, i.e., the substrate strip 10 (conventional current collector), has a metal plating layer 11 on one side of its width direction. Metal foil strips 12 (interchange bodies), typically copper or aluminum foil, are welded to the upper and lower sides of the metal plating layer 11 area to form the composite current collector 1. The entire processing includes roughly three processes: unwinding the substrate strip, welding the substrate strip to the foil, and rewinding the composite current collector. During this process, both the substrate strip and the subsequently welded composite current collector undergo several rolls, inevitably subjecting them to rolling pressure. After rolling, the metal plating area of the substrate strip and the metal plating area after welding the foil strip will stretch. This leads to inconsistent tightness on both sides of the substrate strip or composite current collector in the width direction, especially noticeable when the composite current collector is widened, affecting the stability of the strip (substrate strip or composite current collector) and the processing speed.

[0032] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0035] Please refer to Figures 1 to 13 The composite current collector roll welding forming equipment includes a substrate unwinding mechanism 01, a foil unwinding mechanism 03, a pressure roller mechanism 7, an ultrasonic roll welding mechanism 6, a post-weld inspection mechanism, a dust removal mechanism 04, and a winding mechanism 02 arranged sequentially along a first direction X. A first correction component 51 is provided between the substrate unwinding mechanism 01 and the pressure roller mechanism 7. The substrate strip 10 extends from the substrate unwinding mechanism 01 through the first correction component 51 to the pressure roller mechanism 7. The foil strip 12 extends from the foil unwinding mechanism 03 to the pressure roller mechanism 7 and is pressed and bonded to the substrate strip 10. The substrate strip 10 and the foil strip 12 are welded at the ultrasonic roll welding mechanism 6. The first correction component 51 is located close to the substrate unwinding mechanism 01. An adjusting roller structure 3 is provided between the first correction component 51 and the pressure roller mechanism 7. The adjusting roller structure 3 includes a first roller 31, around which the substrate strip 10 is wound. The first roller 31 is adjustable to adjust the degree of bonding between the first roller 31 and the substrate strip 10.
[0036] Specifically, such as Figure 1 , Figure 2 and Figure 5As shown, the substrate unwinding mechanism 01, foil unwinding mechanism 03, pressure roller mechanism 7, ultrasonic welding mechanism 6, post-weld inspection mechanism, dust removal mechanism 04, and winding mechanism 02 are all mounted on the square tube frame 2. In use, the substrate unwinding mechanism 01 unwinds the substrate strip 10, and the foil unwinding mechanism 03 unwinds the foil strip 12. The substrate strip 10 starts from the substrate unwinding mechanism 01 and is corrected at the first correction component 51 to ensure the stability and accuracy of the substrate strip 10 before it enters the pressure roller mechanism 7 and the ultrasonic welding mechanism 6. Furthermore, the adjusting roller structure 3 set between the first correction component 51 and the pressure roller mechanism 7 adjusts the spatial state of the first roller 31 to adaptively adjust the degree of adhesion between the first roller 31 and the substrate strip 10. Specifically, by adjusting the spatial position of the first roller 31, the substrate strip 10 is kept taut at all points in the width direction to avoid unstable operation caused by inconsistent tension on the inner and outer sides of the substrate strip 10 in the width direction.
[0037] Specifically, such as Figure 5 As shown, the adjusting roller structure 3 further includes a first inner seat 32, a first extension rod 34, and a first outer seat 33. The first inner seat 32 is disposed at one end of the first extension rod 34, and the first outer seat 33 is disposed at the other end of the first extension rod 34. The first end of the first roller 31 is mounted on the first inner seat 32, and the second end of the first roller 31 is mounted on the first outer seat 33. In this embodiment, the first inner seat 32 is fixedly mounted on the square tube frame 2, and the first extension rod 34 connects the first inner seat 32 and the first outer seat 33 into a single unit to facilitate the assembly of the first roller 31. Optionally, the first roller 31 and the first inner seat 32 can be equipped in an adjustable manner, and / or the first roller 31 and the first outer seat 33 can be equipped in an adjustable manner.
[0038] In this embodiment, the first roller 31 includes a rolling part 311 and a fixed part 312. The rolling part 311 is rotatably sleeved on the outside of the fixed part 312. The first end of the fixed part 312 is hinged to the first inner seat 32 through a first pin 3121. The first outer seat 33 includes a seat plate 331 mounted on the first extension rod 34. The seat plate 331 is provided with a fixed shaft seat 332 and a movable shaft seat 333. The movable shaft seat 333 is slidably connected to the seat plate 331 through a slide rail slider assembly. An adjusting screw 334 is rotatably mounted on the fixed shaft seat 332. The adjusting screw 334 is threadedly connected to the movable shaft seat 333. A guide hole 3333 is provided on the movable shaft seat 333. The extending direction of the guide hole 3333 is perpendicular to the axial direction of the adjusting screw 334. The second end of the fixed part 312 is slidably embedded in the guide hole 3333. Specifically, as shown in the figure... Figure 5 and Figure 6As shown, the movable shaft seat 333 has a swing hole 3332 on the side facing the second end of the fixed part 312. The guide hole 3333 is an oblong hole that connects to the swing hole 3332. The second end of the fixed part 312 is provided with a second pin 3122 that is adapted to the guide hole 3333. The second pin 3122 is embedded in the guide hole 3333. In this embodiment, the adjusting screw 334 is inserted into the assembly hole 3331 and is rotatably connected to the movable shaft seat 333.
[0039] Preferably, there are two fixed bearing seats 332, with an adjusting screw 334 spanning between the two fixed bearing seats 332, and a movable bearing seat 333 positioned between the two fixed bearing seats 332. In use, by rotating the adjusting screw 334, the movable bearing seat 333 is threadedly driven by the adjusting screw 334 to move between the two fixed bearing seats 332. This drives the first roller 31 to swing around the first pin 3121 within a certain angle range, thereby adjusting the degree of contact between the first roller 31 and the substrate belt 10. This facilitates tensioning of the inner and outer sides of the substrate belt 10 in the width direction, ensuring the stability and speed of the substrate belt 10, especially the wide-width substrate belt 10.
[0040] The guide hole 3333 here, together with the second pin 3122, serves to assemble the second end of the fixing part 312, while preventing the first roller 31 from interfering with the moving shaft seat 333 during the swinging process of the first pin 3121.
[0041] The composite current collector roll welding forming equipment also includes a second correction component 52, which is located near the pressure roller mechanism 7. The adjusting roller structure 3 is located between the first correction component 51 and the second correction component 52. In this embodiment, the first correction component 51 is located near the substrate unwinding mechanism 01, and the second correction component 52 is located near the pressure roller mechanism 7. Both the first correction component 51 and the second correction component 52 act on the substrate strip 10. The substrate strip 10 receives the first correction at the substrate unwinding mechanism 01. Subsequently, the adjusting roller structure 3 ensures that the inner and outer sides of the substrate strip 10 have consistent tension in the width direction. At the same time, the substrate strip 10 is corrected a second time before entering the pressure roller mechanism 7. Thus, through the combined action of the first correction component 51, the adjusting roller structure 3, and the second correction component 52, the substrate strip 10 can be stably and rapidly transported before entering the pressure roller mechanism 7, while ensuring the accuracy of the substrate strip 10 entering the pressure roller mechanism 7 and guaranteeing the processing quality.
[0042] Furthermore, such as Figure 1 and Figure 7As shown, the composite current collector roll welding forming equipment also includes a tension swing roller 4, which is located between the adjusting roller structure 3 and the second correction component 52. The tension swing roller 4 includes a swing roller frame 41 set on the square tube frame 2. A swing roller shaft 42 is rotatably mounted on the swing roller frame 41. Two swing roller plates 43 are fixedly mounted on the swing roller shaft 42. A swing roller 44 and a counterweight roller 45 are spanned across the two swing roller plates 43. The swing roller shaft 42 is located between the swing roller 44 and the counterweight roller 45. In this embodiment, the substrate strip 10 is wound around the swing roller 44. A motor set on the square tube frame 2 drives the swing roller shaft 42 to rotate, so that the swing roller 44 can swing within a certain angle range, thereby allowing the swing to be implemented according to the actual situation so that the substrate strip 10 is in a stable tensioned state.
[0043] like Figure 7 As shown, the swing roller plate 43 has an adjustment groove 431. The end of the counterweight roller 45 is adjustablely embedded in the adjustment groove 431, allowing the counterweight roller 45 to move within the adjustment groove 431 to approach or move away from the swing roller shaft 42. Optionally, an adjustment screw 46 is rotatably mounted on the swing roller plate 43, extending into the adjustment groove 431 and threadedly connected to the counterweight roller 45, allowing the counterweight roller 45 to slide within the adjustment groove 431. This configuration allows for convenient adjustment of the swing radius of the counterweight roller 45, enabling better adjustment of the tension swing roller 4 according to actual working conditions to meet processing requirements.
[0044] like Figure 8 and Figure 9 As shown, the ultrasonic roll welding mechanism 6 includes a base plate 61, which is mounted on the square tube frame 2. A roll welding frame 62 is arranged on the base plate 61, and an active welding head 63 is arranged on the roll welding frame 62. A smoothing roller 64 is adjustablely arranged on the base plate 61. A driven welding head 65 adapted to the active welding head 63 is coaxially mounted on the smoothing roller 64. The smoothing roller 64 extends along the width direction of the substrate strip 10. The substrate strip 10 and the foil strip 12 are both located between the active welding head 63 and the driven welding head 65, and overlap the smoothing roller 64.
[0045] Furthermore, a longitudinal plate 66 is disposed on the base plate 61, and a first roller seat 67 is slidably mounted on the longitudinal plate 66. A smoothing roller 64 is rotatably mounted on the first roller seat 67. The ultrasonic welding mechanism 6 also includes a first driving member 68, which drives the first roller seat 67 to slide relative to the longitudinal plate 66 to approach or move away from the active welding head 63. Optionally, the first driving member 68 includes, but is not limited to, a cylinder, a hydraulic cylinder, or an electric actuator. In use, the first driving member 68 drives the first roller seat 67 to move upward relative to the longitudinal plate 66, so that the smoothing roller 64 and the driven welding head 65 move upward along the longitudinal direction Z. The substrate strip 10 and the foil strip 12 are welded between the active welding head 63 and the driven welding head 65. The smoothing roller 64 supports the substrate strip 10 in the width direction. The driven welding head 65 is coaxially arranged with the smoothing roller 64, which can ensure that the inner and outer sides of the substrate strip 10 in the width direction are in a taut state during welding, which is beneficial to ensuring the welding accuracy of the substrate strip 10 and the foil strip 12.
[0046] Furthermore, such as Figure 8 As shown, the ultrasonic roll welding mechanism 6 also includes a first auxiliary roller group 690a, a second auxiliary roller group 690b, and a third auxiliary roller group 690c arranged sequentially along the conveying direction of the substrate strip 10. A smoothing roller 64 is positioned between the second auxiliary roller group 690b and the third auxiliary roller group 690c. The substrate strip 10 and the foil strip 12 pass sequentially through the first auxiliary roller group 690a, the second auxiliary roller group 690b, and the third auxiliary roller group 690c. Here, the first auxiliary roller group 690a, the second auxiliary roller group 690b, the smoothing roller 64, and the third auxiliary roller group 690c limit the substrate strip 10 and the foil strip 12 in the longitudinal direction Z before and after the welding position, ensuring that the substrate strip 10 and the foil strip 12 are in a roughly horizontal running state before and after the welding position. This improves the welding accuracy of the substrate strip 10 and the foil strip 12 while effectively preventing them from deviating.
[0047] Optionally, the second auxiliary roller group 690b and the third auxiliary roller group 690c have the same structure. The following description uses the second auxiliary roller group 690b as an example. Specifically, the second auxiliary roller group 690b includes a first roller frame 6910 disposed on the base plate 61. A first auxiliary roller 6911 and a second auxiliary roller 6912 are adjustablely disposed on the first roller frame 6910. The substrate strip 10 and the foil strip 12 are located between the first auxiliary roller 6911 and the second auxiliary roller 6912. The first auxiliary roller 6911 and the second auxiliary roller 6912 are arranged in parallel and can move closer to or further away from each other. In this embodiment, the first roller frame 6910 is mounted on the base plate 61 via the second roller seat 691. A first adapter plate 6913 is disposed on the first roller frame 6910. A first adjusting plate 6914 and a second adjusting plate 6915 are adjustablely mounted on the first adapter plate 6913. A first auxiliary roller 6911 is mounted on the first adjusting plate 6914, and a second auxiliary roller 6912 is mounted on the second adjusting plate 6915. With this arrangement, the second auxiliary roller 6912 supports the substrate strip 10 and the foil strip 12, while the first auxiliary roller 6911 presses down on the substrate strip 10 and the foil strip 12. The two cooperate to longitudinally limit the substrate strip 10 and the foil strip 12 in the Z-direction.
[0048] like Figure 10 As shown, the first adapter plate 6913 is provided with a first hinge hole 69131, a first arc-shaped hole 69132, a second hinge hole 69134, and a second arc-shaped hole 69135. The first hinge hole 69131 is located at the center of the first arc-shaped hole 69132, and the second hinge hole 69134 is located at the center of the second arc-shaped hole 69135. A first hinge pin (not shown in the figure) is rotatably installed in the first hinge hole 69131 and is connected to the first adjusting plate 6914. A first adjusting pin 69133 is slidably embedded in the first arc-shaped hole 69132 and is connected to the first adjusting plate 6914. Correspondingly, a second hinge pin (not shown in the figure) is rotatably installed in the second hinge hole 69134, and the second hinge pin is connected to the second adjusting plate 6915. A second adjusting pin 69136 is slidably embedded in the second arc-shaped hole 69135, and the second adjusting pin 69136 is connected to the second adjusting plate 6915. For example, the first adjusting plate 6914 can rotate around the central axis of the first hinge pin, and its adjustment range depends on the sliding range of the first adjusting pin 69133 in the first arc-shaped hole 69132. In this way, the spatial position adjustment of the first adjusting plate 6914 and the second adjusting plate 6915 can be realized, so as to realize the position adjustment of the first auxiliary roller 6911 and the second auxiliary roller 6912, so as to adjust according to the actual working conditions to better tension the substrate strip 10.
[0049] The first auxiliary roller group 690a includes a third auxiliary roller 6916 and a fourth auxiliary roller 6917, which are mounted on the first roller frame 6910. The substrate strip 10 and the foil strip 12 are positioned on the third auxiliary roller 6916 and the fourth auxiliary roller 6917. The third auxiliary roller 6916 supports the substrate strip 10 and the foil strip 12, while the fourth auxiliary roller 6917 presses down on them. Together, they limit the substrate strip 10 and the foil strip 12 in the longitudinal Z-direction. In this embodiment, the third auxiliary roller 6916 and the fourth auxiliary roller 6917 are fixedly mounted on the first roller frame 6910. In other embodiments, the third auxiliary roller 6916 and the fourth auxiliary roller 6917 may also be adjustable, similar to the first auxiliary roller 6911 and the second auxiliary roller 6912.
[0050] like Figure 11 As shown, the pressure roller mechanism 7 includes a third roller seat 71 disposed on the square tube frame 2. A driven pressure roller 72 and a driving pressure roller 73 are disposed on the third roller seat 71. The driving pressure roller 73 can move closer to or further away from the driven pressure roller 72. The substrate strip 10 and the foil strip 12 are located between the driving pressure roller 73 and the driven pressure roller 72. In this embodiment, the driven pressure roller 72 and the driven welding head 65 are substantially flush in the longitudinal Z direction. The driving pressure roller 73 and the driven pressure roller 72 cooperate to press the foil strip 12 tightly against the substrate strip 10, facilitating subsequent roll welding. The substantially flush alignment of the driven pressure roller 72 and the driven welding head 65 in the longitudinal Z direction ensures that the substrate strip 10 and the foil strip 12 enter the welding position in a stable posture after roll pressing, avoiding failure of the roll pressing state of the substrate strip 10 and the foil strip 12 during the process. In this embodiment, the active pressure roller 73 is mounted on the first adjusting roller frame 731. The first adjusting roller frame 731 is equipped with a first guide rod 732, which extends longitudinally along the Z direction. The first guide rod 732 is slidably connected to the third roller seat 71. The third roller seat 71 is provided with a telescopic component for driving the first adjusting roller frame 731 to move closer to or away from the driven pressure roller 72 along the longitudinal direction Z. The telescopic component includes, but is not limited to, a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.
[0051] like Figure 12 As shown, the composite current collector roll welding forming equipment also includes a smoothing mechanism 8 disposed after the ultrasonic roll welding mechanism 6, including a fourth roller seat 81, an active smoothing roller 83 and a driven smoothing roller 82. The fourth roller seat 81 is mounted on the square tube frame 2, the active smoothing roller 83 is rotatably mounted on the fourth roller seat 81, and the driven smoothing roller 82 is adjustablely mounted on the fourth roller seat 81. The driven smoothing roller 82 can approach or move away from the active smoothing roller 83, and the welding marks on the foil strip 12 and the substrate strip 10 are within the rolling range of the active smoothing roller 83 and the driven smoothing roller 82.
[0052] Specifically, a first support plate (not shown in the figure) is provided on the fourth roller seat 81. A second support plate 84 is provided on the side of the first support plate facing the active roller 83. The second support plate 84 is slidably connected to the first support plate via a second guide rod 85 extending longitudinally Z. The driven roller 82 is rotatably mounted on the wheel frame 821. The second support plate 84 is located between the wheel frame 821 and the first support plate. The wheel frame 821 is slidably connected to the second support plate 84 via a third guide rod 86. A buffer spring 87 is sleeved on the third guide rod 86 and pressed between the wheel frame 821 and the second support plate 84. A cylinder is provided on the first support plate to drive the second support plate 84 to move closer to or away from the active roller 83 longitudinally Z. The active roller 83 is driven to rotate by a motor mounted on the fourth roller seat 81. During the operation of the driven roller 82 approaching the active roller 83, the buffer spring 87 provides a buffering force to prevent the driven roller 82 from making hard contact with the composite current collector 1, thus preventing damage to the composite current collector 1.
[0053] like Figure 13 As shown, the composite current collector roll welding forming equipment also includes a main drive mechanism 9, which is located behind the smoothing mechanism 8 and is used to drive the welding body of the substrate strip 10 and foil strip 12. Specifically, the main drive mechanism 9 includes a fifth roller seat 91, on which an assembly space 910 is arranged, and also includes a main drive roller 92 and a driven roller 93. The main drive roller 92 is rotatably mounted in the assembly space 910, and a second adjusting roller frame 931 is adjustablely mounted in the assembly space 910. The driven roller 93 is rotatably mounted on the second adjusting roller frame 931, and a fourth guide rod 94 extending longitudinally Z is provided on the second adjusting roller frame 931. The fourth guide rod 94 is slidably connected to the fifth roller seat 91, and a cylinder is provided on the fifth roller group for driving the second adjusting roller frame 931 to move longitudinally Z. This allows adjustment of the gap between the main drive roller 92 and the driven roller 93.
[0054] Furthermore, a dust removal channel 911 is provided on the fifth roller seat 91. The dust removal channel 911 is located on one side of the main drive roller 92 and is connected to the assembly space 910. The main drive roller 92 is located at the inlet end of the dust removal channel 911. A dust removal air knife 97 and a brush 95 are configured at the inlet end of the dust removal channel 911. The brush 95 is attached to the main drive roller 92. The main drive roller 92 is located between the dust removal air knife 97 and the brush 95. The outlet end of the dust removal channel 911 is connected to a negative pressure source (not shown in the figure) to suck out and remove impurities cleaned from the main drive roller 92.
[0055] In this embodiment, a dust collection hood 96 is provided at the outlet end of the dust removal channel 911, and the dust collection hood 96 is connected to a negative pressure source. Furthermore, a cover plate 98 is provided at the inlet end of the dust removal channel 911 on the side of the brush 95. Both the cover plate 98 and the dust collection hood 96 effectively improve the sealing of the dust removal channel 911, effectively removing impurities while preventing their diffusion.
[0056] In some embodiments, the dust removal mechanism 04 is used to remove dust from the substrate strip 10 or the welded body of the substrate strip 10 and the foil strip 12. The dust removal mechanism 04 can be any existing dust removal component, without specific limitations. It should be noted that the composite current collector roll welding forming equipment also includes a third correction component 05, which is located close to the winding mechanism 02, and is used to correct the composite current collector 1 before winding to ensure winding accuracy.
[0057] The first correction component 51, the second correction component 52, and the third correction component 05 can be any existing current collector correction component, without any specific restrictions.
[0058] In some embodiments, the composite current collector roll welding forming equipment further includes an iron removal component, which is disposed on the conveying path of the substrate strip 10 or the composite current collector 1, and is used to remove magnetic impurities on the substrate strip 10 or the composite current collector 1 by magnetic attraction. Multiple iron removal components may be present, including at least one magnetic adsorption surface, with the substrate strip 10 or the composite current collector 1 slidingly attached to the adsorption surface.
[0059] In this embodiment, the width of the substrate strip 10 is 50mm-550mm. By using the composite current collector roll welding forming equipment provided in this embodiment, the production speed can reach 20m / min.
