Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a multi-material strip composite rolling device. Background Technology

[0002] The carbon tape lamination process is a crucial step in battery manufacturing. Typically, during electrode manufacturing, carbon tape is bonded to the surface of foil, or other carbon tapes are bonded to the surface of foil, creating grooves in the foil and other tapes to reserve space for subsequent carbon layer coating.

[0003] The following technical problems exist in the actual roll forming process: the composite rollers are fixedly installed, which makes the spacing between the composite rollers fixed. The cost of adjusting the pressure between the composite rollers during production is high, so there is a problem that the spacing between the composite rollers cannot be adjusted in real time according to the process design requirements; in the process of material strip forming, when forming and pressing material strips of different widths, the position of the pressing surface of the composite roller cannot be changed, so there is a problem of correction.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

In the description of this utility model, unless otherwise stated, "several" means one or more, and "multiple" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The following is for reference. Figures 1 to 9 This invention describes a multi-material strip composite roller pressing device provided according to an embodiment of the present invention.

[0034] like Figures 1 to 9 As shown, the multi-material strip composite roller pressing device according to this embodiment of the invention can be applied in a battery manufacturing production line. Specifically, it can complete the strip roller pressing composite work. The multi-material strip composite roller pressing device of this embodiment can quickly adjust the spacing between the composite roller components and the composite axis to adapt to the composite requirements of strips with different widths and different composite pressures.

[0035] The multi-material strip composite roller pressing device has a first direction, a second direction, and a third direction that are perpendicular to each other. In this embodiment, it is assumed that the first direction is the front-to-back direction, the second direction is the left-to-right direction, and the third direction is the up-to-down direction.

[0036] like Figures 1 to 3 As shown, the structure of the multi-material belt composite roller pressing device includes a frame 100, a composite roller assembly, and an adjustment mechanism 300.

[0037] The frame 100 provides a mounting position and support for the composite pressure roller assembly and the adjustment mechanism 300. The specific structure of the frame 100 is not limited and can be set according to actual design requirements.

[0038] The composite pressure roller assembly is movably mounted on the frame 100 and can move linearly relative to the frame 100. There are two composite pressure roller assemblies, and the two composite pressure roller assemblies are arranged at a certain interval along a third direction so that the two composite pressure roller assemblies can jointly define a roller pressing channel, which extends through the machine along a first direction.

[0039] Specifically, each composite pressure roller assembly includes a composite pressure roller component 210 and a composite drive component 220. The length of the composite pressure roller component 210 extends along a second direction. The output end of the composite drive component 220 is connected to one end of the composite pressure roller component 210 to drive the composite pressure roller component 210 to rotate relative to the frame 100 around its own central axis. The composite drive component 220 includes a drive motor and a transmission structure such as a coupling. The two composite pressure roller components 210 rotate in opposite directions, are arranged opposite to each other and spaced apart along a third direction, and the distance between the two composite pressure roller components 210 forms a roller pressing channel. When multiple strips enter the roller pressing channel, the two composite pressure roller components 210 can apply roller pressing action to the multiple strips during rotation, so that the multiple strips can be combined together.

[0040] An adjustment mechanism 300 is disposed on the frame 100. There are two adjustment mechanisms 300, and the two adjustment mechanisms 300 are respectively disposed on both sides of the frame 100 along the second direction. In this embodiment, the adjustment mechanism 300 located on one side of the frame 100 is designated as the first adjustment mechanism, and the adjustment mechanism 300 located on the other side of the frame 100 is designated as the second adjustment mechanism.

[0041] The two adjustment mechanisms 300 are configured to drive the two composite pressure roller assemblies to move in the same direction along the second direction to adjust the position of the roller pressing channel in the second direction, so that the composite axis of the roller pressing channel can coincide with the central axis of the material strip entering the roller pressing channel; and the two adjustment mechanisms 300 are also configured to drive the two composite pressure roller assemblies to move closer to each other or further away from each other along the third direction to adjust the size of the roller pressing channel in the third direction, thereby achieving adjustment of different composite pressures.

[0042] Specifically, each adjustment mechanism 300 includes a first drive assembly 310 and a second drive assembly 320. Therefore, the frame 100 is provided with a first drive assembly 310 and a second drive assembly 320 on both sides along the second direction. In the same adjustment mechanism 300, there is one first drive assembly 310. The output end of the first drive assembly 310 is connected to one of the composite pressure roller assemblies. The first drive assemblies 310 located on both sides of the frame 100 are configured to drive the same composite pressure roller assembly to move linearly along a third direction, while the other composite pressure roller assembly remains stationary in the third direction. By operating the two first drive assemblies 310 simultaneously, one composite pressure roller assembly is controlled to move relative to the other composite pressure roller assembly to either side along the third direction, causing the distance between the two composite pressure roller assemblies to increase or decrease, thereby adjusting the size of the roller pressing channel according to the composite pressure condition.

[0043] In the same adjustment mechanism 300, two second drive components 320 are provided, and the two second drive components 320 are respectively arranged in a one-to-one correspondence with the two composite pressure roller assemblies. In this embodiment, each composite pressure roller assembly has a second drive component 320 on both sides. The second drive components 320 located on both sides of the frame 100 are configured to drive the same composite pressure roller assembly to move linearly in the same direction along the second direction. By activating the second drive components 320 on both sides of the composite pressure roller assembly, one second drive component 320 applies a pushing force to the composite pressure roller assembly, and the other second drive component 320 applies a pulling force to the composite pressure roller assembly, thereby realizing the linear movement of the composite pressure roller assembly along the second direction. The two composite pressure roller assemblies can move linearly simultaneously or sequentially under the driving action of the second drive components 320.

[0044] It is understood that the first drive assembly 310 and the second drive assembly 320 can be linear drive devices such as electric cylinders, pneumatic cylinders, and lead screw drive devices, which can accurately adjust the position of the composite pressure roller assembly in the second direction or in the third direction.

[0045] In some examples, for each composite pressure roller assembly, the output ends of the second drive components 320 located on both sides of the composite pressure roller assembly are respectively connected to both ends of the composite pressure roller assembly, enabling the composite pressure roller assembly to move in the same direction along a second direction. The output ends of the first drive components 310 located on both sides of the frame 100 are respectively connected to two second drive components 320 on the same composite pressure roller assembly, enabling the composite pressure roller assembly and the two second drive components 320 on it to move together along a third direction.

[0046] In other examples, the output ends of the first drive components 310 located on both sides of the frame 100 are respectively connected to both ends of the same composite pressure roller assembly, enabling the composite pressure roller assembly to move along a third direction, thereby adjusting the spacing between the two composite pressure roller assemblies in the third direction. Furthermore, the output ends of the second drive components 320 located on both sides of the composite pressure roller assembly are respectively connected to the first drive components 310 located on both sides of the frame 100, enabling the composite pressure roller assembly and the two first drive components 310 thereon to move along a second direction. For another composite pressure roller assembly, the output ends of the second drive components 320 located on both sides of the frame 100 are respectively connected to both ends of the composite pressure roller assembly, enabling the composite pressure roller assembly to move along a second direction, causing the two composite pressure roller assemblies to move an appropriate distance along the second direction according to the width of the material strip, thereby adjusting the position of the composite axis of the roller pressing channel in the second direction.

[0047] Of course, it is not excluded that in other embodiments, each composite pressure roller assembly may be provided with a first drive assembly 310 and a second drive assembly 320 at either end, and the first drive assembly 310 and the second drive assembly 320 together constitute a dual-axis motion mechanism, enabling the composite pressure roller assembly to move along the second direction and the third direction respectively.

[0048] In some embodiments, such as Figures 1 to 7 As shown, each composite pressure roller assembly also includes a mounting base 240 and a snap-fit ​​shaft 230. Specifically, the composite pressure roller component 210 has mounting bases 240 and snap-fit ​​shafts 230 on both sides along the second direction, meaning each composite pressure roller assembly has two mounting bases 240 and two snap-fit ​​shafts 230. The snap-fit ​​shafts 230 and mounting bases 240 are rotatably connected via bearings, allowing the snap-fit ​​shafts 230 to rotate relative to the mounting bases 240 around their central axis. Each snap-fit ​​shaft 230 is configured to insert into and snap onto one end of the composite pressure roller component 210 along the second direction. In this case, the snap-fit ​​shaft 230 and the composite pressure roller component 210 are coaxially arranged, allowing the snap-fit ​​shaft 230 to drive the composite pressure roller component 210 to rotate together.

[0049] Specifically, such as Figure 5 and Figure 7 As shown, one end of the snap-fit ​​shaft 230 is a frustum-shaped insertion end 231. The insertion end 231 is provided with one or more snap blocks 232. The composite pressure roller 210 is provided with a slot, which is located on one side of the composite pressure roller 210 along the second direction. The snap blocks 232 are configured to be able to snap into or disengage from the slot along the second direction. Because the insertion end 231 is frustum-shaped, it can play a guiding role, allowing the insertion end 231 with snap blocks 232 to be smoothly inserted into the slot of the composite pressure roller 210.

[0050] Understandably, this arrangement facilitates the installation and removal of the composite pressure roller 210 from the snap-fit ​​shaft 230, and allows for easy replacement of composite pressure rollers 210 of different sizes. When the insertion end 231 is provided with multiple snap-fit ​​blocks 232, these blocks are arranged circumferentially around the axis of the snap-fit ​​shaft 230 on the outer circumferential surface of the insertion end 231. The specific shape of the snap-fit ​​blocks 232 is not limited. When the snap-fit ​​blocks 232 move along the second direction with the insertion end 231 and snap into the slots of the composite pressure roller 210, the composite pressure roller 210 can engage with the insertion end 231, allowing the composite pressure roller 210 to rotate along with the snap-fit ​​shaft 230.

[0051] Of course, it is possible that the composite pressure roller 210 is equipped with a locking block 232 and the insertion end 231 is equipped with a locking groove.

[0052] In the same composite pressure roller assembly, the output end of the composite drive 220 is fixedly connected to one of the clamping shafts 230. When the composite drive 220 is running, the output end of the composite drive 220 can drive the clamping shaft 230 to rotate along its own central axis, causing the composite pressure roller assembly 210 to rotate and apply a rolling effect to the material strip entering the roller pressing channel. The composite drive 220 includes a drive motor, which can be connected to the end of the clamping shaft 230 away from the insertion end 231 via a transmission structure such as a coupling.

[0053] It is understood that the specific shape of the mounting base 240 is not limited, and the composite drive component 220 is fixedly mounted on the mounting base 240. The mounting base 240 can be connected to the output end of the first drive assembly 310 or the output end of the second drive assembly 320. By operating the second drive assembly 320 and driving the snap-fit ​​shaft 230 away from the composite pressure roller component 210 in the second direction, the insertion end 231 can be disengaged from the snap-fit ​​groove of the composite pressure roller component 210, thereby releasing the snap-fit ​​fixing effect between the snap-fit ​​shaft 230 and the composite pressure roller component 210. In this embodiment, the composite drive components 220 in the two composite pressure roller assemblies are located on the same side of the frame 100 in the second direction.

[0054] In some embodiments, such as Figures 1 to 3As shown, each first drive assembly 310 includes a lead screw adjustment assembly 312, a first support 313, and a first drive member 311. The lead screw adjustment assembly 312 includes several lead screws extending in a third direction, and these lead screws are threadedly connected to the first support 313. Specifically, the first support 313 has several threaded holes for connecting to the lead screws. The first drive member 311 is configured to drive the several lead screws to rotate simultaneously around its own central axis. Two mounting seats 240 of one of the composite pressure roller assemblies are respectively disposed on the first supports 313 located on both sides of the frame 100. When the first drive member 311 operates and drives the lead screw adjustment assembly 312, the first supports 313 can drive the composite pressure roller assembly to move in a third direction.

[0055] Furthermore, such as Figures 1 to 7 As shown, the first support 313 is slidably connected to the mounting base 240 along the second direction, and the first support 313 is slidably connected to the frame 100 along the third direction. Specifically, two first guide rail slider pairs 710 are provided between the mounting base 240 and the first support 313, and two second guide rail slider pairs 720 are provided between the first support 313 and the frame 100, so that the mounting base 240 can move smoothly relative to the first support 313 along the second direction, and the first support 313 can drive the mounting base 240 to move smoothly relative to the frame 100 along the third direction.

[0056] Each first support 313 is provided with a second drive component 320. The second drive component 320 is fixed relative to the first support 313 and can move along a third direction with the first support 313. The output end of the second drive component 320 is fixedly connected to the mounting base 240. In this embodiment, the second drive component 320 is located above the mounting base 240. When the second drive component 320 is working, the output end of the second drive component 320 can drive the mounting base 240 to move the snap-fit ​​shaft 230 along the second direction.

[0057] Furthermore, the frame 100 is provided with second drive assemblies 320 on both sides along the second direction. The second drive assemblies 320 are fixed to the frame 100. The two mounting seats 240 of the other composite pressure roller assembly are slidably connected to the frame 100 along the second direction. In this embodiment, the frame 100 is provided with second supports 110 on both sides along the second direction. The mounting seat 240 is located above the second support 110. A third guide rail slider pair 730 is provided between the mounting seat 240 and the second support 110, so that the mounting seat 240 can move stably relative to the second support 110 along the second direction. In addition, the two mounting seats 240 of the composite pressure roller assembly are respectively connected to the output ends of the second drive assemblies 320 located on both sides of the frame 100. The second drive assemblies 320 are fixedly mounted on the second supports 110.

[0058] In this embodiment, each lead screw adjusting assembly 312 includes two lead screws spaced apart along a first direction and threadedly connected to a corresponding first support 313. The lead screws are mounted on the frame 100 and are rotatable relative to the frame 100 about an axis extending along a third direction. The first drive unit 311 includes a motor and a transmission structure. The motor drives the two lead screws to rotate simultaneously about the same direction via a transmission structure such as a right-angle steering gear. The two lead screw adjusting assemblies 312 operate simultaneously, driving one of the composite pressure roller assemblies and its second drive assembly 320 to move stably in a straight line along a third direction.

[0059] like Figure 4 and Figure 5 As shown, the composite drive component 220, the snap-fit ​​shaft 230, and the mounting base 240, all located on one side of the frame 100, are interconnected and together form a composite drive assembly. This composite drive assembly can dock with one end of the composite pressure roller component 210 and apply a rotational drive. Figure 6 and Figure 7 As shown, the snap-fit ​​shaft 230 and mounting base 240, both located on the other side of the frame 100, are interconnected and together form a support assembly. The support assembly can dock with the other end of the composite pressure roller 210 and provide support. The support assembly and the composite drive assembly are located on both sides of the composite pressure roller 210, respectively, and cooperate with each other to drive the composite pressure roller 210 to rotate on its own under stable support.

[0060] In a specific embodiment, such as Figures 1 to 7 As shown, the second drive assembly 320 located on one side of the frame 100 along the second direction is an electric linear drive device, which can be a push rod motor, a lead screw motor, etc., and can precisely control the distance the composite pressure roller assembly moves along the second direction. In this embodiment, the second drive assembly 320 uses a lead screw motor, and the nut seat on the lead screw motor is fixedly connected to the corresponding mounting base 240. The second drive assembly 320 located on the other side of the frame 100 along the second direction is a telescopic cylinder, and the movable rod of the telescopic cylinder is fixedly connected to the corresponding mounting base 240.

[0061] Understandably, when the electric linear drive is powered on, its output can drive the composite pressure roller assembly to move along the second direction. At the same time, the telescopic cylinder operates and provides a driving force for the composite pressure roller assembly. In this case, the electric linear drive can provide high-precision drive control, and the telescopic cylinder can provide high movement speed and impact resistance, thereby achieving high-speed and high-precision control of the composite pressure roller assembly to move along the second direction.

[0062] When using the multi-material strip composite roller pressing device provided in this embodiment of the utility model, the operator can drive the two composite roller assemblies on the frame 100 to move relatively linearly in a third direction through the adjustment mechanism 300, so that the two composite roller assemblies can move closer to each other or further away from each other, thereby realizing the rapid adjustment of the distance between the two composite roller assemblies, completing the size adjustment of the roller pressing channel, ensuring good control of the pressing force on the material strip, and finally achieving the effect of adjusting different composite pressures to meet the needs of the roller pressing composite process.

[0063] Furthermore, the operator can use the adjustment mechanism 300 to drive the two composite pressure roller assemblies to move linearly relative to the frame 100 on either side of the second direction, and adjust the composite axis of the composite pressure roller assembly in real time and quickly, so that the composite axis of the composite pressure roller assembly can coincide with the central axis of the material strip entering the roller pressing channel, ensuring a good roller pressing composite effect on the material strip, and thus adapting to the composite needs of material strips of different widths.

[0064] In some embodiments, such as Figure 1 , Figure 2 , Figure 8 and Figure 9 As shown, the multi-material strip composite roller pressing device also includes a guide belt member 400. The guide belt member 400 is disposed on the belt path of the multi-material strip composite roller pressing device and is located near the feed inlet of the roller pressing channel. The guide belt member 400 can guide the material strip to enter the roller pressing channel. The guide belt member 400 has mounting holes 430 at both ends along the second direction. Screws are passed through the mounting holes 430 to detachably connect the guide belt member 400 to the frame 100.

[0065] Specifically, the guide belt 400 is provided with an inlet 410 and a guide surface 420. The inlet 410 extends through the main material belt 610 in a first direction, allowing the main material belt 610 to pass through. Moreover, the inlet 410 is configured to guide the main material belt 610 when it enters the roller pressing channel. In this embodiment, the inlet 410 is rectangular when viewed in the first direction.

[0066] The guide belt member 400 has a guide surface 420 on the side near the roller pressing channel along the first direction. Specifically, the feed inlet 410 has guide surfaces 420 on both sides along the third direction. The guide surfaces 420 are inclined and configured to guide the composite belt 620 when it enters the roller pressing channel. The guide surface 420 extends from its end near the feed inlet 410 along the third direction away from the roller pressing channel. The extending direction of the guide surface 420 forms a certain angle with the third direction.

[0067] Understandably, after the main material belt 610 passes through the feed inlet 410 of the guide belt 400, the composite belts 620 located on both sides of the main material belt 610 adhere to the main material belt 610 under the guiding effect of the corresponding guide surfaces 420, and enter the roller pressing channel together.

[0068] Of course, it is possible that a guide surface 420 is provided only on one side of the feed inlet 410 along the third direction.

[0069] In some embodiments, such as Figures 1 to 3 As shown, the multi-material belt composite roller pressing device further includes a first support roller 510 and a second support roller 520. The roller pressing channel has a feed side along a first direction and a discharge side along the other side along the first direction. The first support roller 510 extends along a second direction, is mounted on the frame 100, and is rotatable relative to the frame 100 about its central axis. The first support roller 510 is located on the feed side and is configured to guide the composite belt 620. The second support roller 520 extends along the second direction, is mounted on the frame 100, and is rotatable relative to the frame 100 about its central axis. The second support roller 520 is located on the discharge side and is configured to guide the waste belt 630.

[0070] The roller pressing channel has a first guide roller 510 and a second guide roller 520 on both sides along the third direction. It is understood that the first guide rollers 510 on both sides of the roller pressing channel guide the two composite belts 620 respectively, while the second guide rollers 520 on both sides of the roller pressing channel guide the two waste belts 630 respectively, preventing the belts from jamming during the lamination process. The waste belts 630 can be protective films.

[0071] In this embodiment, the first support roller 510 and the second support roller 520 located on the same side of the roller pressing channel along a third direction are arranged opposite to each other and spaced apart in the first direction.

[0072] Of course, it is not excluded that the first support roller 510 and the second support roller 520 may be provided on one side of the roller pressing channel along the third direction.

[0073] In some embodiments, such as Figure 3As shown, the multi-material belt composite roller pressing device also includes a pressure roller 530 and a second driving component 540. The pressure roller 530 extends along a second direction and is located on the discharge side. Two pressure rollers 530 are provided, and each pressure roller 530 is arranged in a one-to-one correspondence with one of the two composite roller assemblies, so that the pressure rollers 530 and the composite roller assemblies together form a side pressure channel. The side pressure channel can be used to tension and guide the waste belt 630, thereby achieving rapid separation of the composite belt 620 and the waste belt 630.

[0074] The second drive unit 540 is fixedly mounted on the frame 100. The output end of the second drive unit 540 is connected to the pressure roller 530. The second drive unit 540 is configured to drive the pressure roller 530 closer to or further away from the composite pressure roller assembly to adjust the size of the side pressure channel. The second drive unit 540 can be a linear drive device such as a cylinder or an electric cylinder.

[0075] In this embodiment, the pressure roller 530 and the composite pressure roller 210 are arranged at intervals along the first direction. Each end of the pressure roller 530 is provided with a second driving member 540, which is mounted on the frame 100. The second driving member 540 is a slide cylinder, and the end of the pressure roller 530 is connected to the slide of the slide cylinder. When the slide cylinder is working, the pressure roller 530 can move closer to or further away from the composite pressure roller 210 along the first direction, thereby adjusting the size of the side pressure channel.
