Description

Technical Field

[0002] Battery current collectors are a crucial component of batteries, responsible for carrying the positive and negative electrode materials and collecting the current generated by the active materials during charging and discharging. The mesh size and filament diameter of the current collector's pore structure are important indicators of its performance, and the uniformity of the mesh structure also affects its mechanical strength. An uneven mesh structure can cause the current collector to deform or crack during battery charging and discharging, reducing the battery's safety and stability.

[0003] The size of the equipment error in producing current collectors is the key to determining the uniformity of their mesh structure. Equipment with smaller errors can more accurately control the size and shape of the current collector, but the existing equipment for producing current collectors has larger errors.

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0051] Please see Figures 1 to 21 This utility model discloses a current collector processing device 200, which is mainly used to cut and stamp metal coils 20 to form metal mesh. One embodiment of the current collector processing device 200 includes a frame 210, a second cutter 230, a first cutter 220, a drive mechanism 250, and an adaptive structure 260.

[0052] The first cutter 220 has a first mating surface 222 on the side opposite to the second cutter 230, and the second cutter 230 has a second mating surface 232 on the side opposite to the first cutter 220. The first mating surface 222 and the second mating surface 232 guide the engagement and guide the second cutting edge 231 of the second cutter 230 to move in alignment with the first cutting edge 221 of the first cutter 220, thereby ensuring the accuracy of the alignment and facilitating the improvement of the material utilization rate of the coil 20. The drive mechanism 250 is mounted on the frame 210 and connected to the second cutter 230 through the adaptive structure 260, thereby facilitating the cutting and punching of the coil 20 to form the mesh structure 21.

[0053] In this embodiment, the adaptive structure 260 includes a self-aligning bearing 261 and an elastic support assembly. The moving end of the drive mechanism 250 is movably connected to the second tool 230 through the self-aligning bearing 261. The moving end of the drive mechanism 250 also elastically abuts against the second tool 230 through the elastic support assembly, so that the second mating surface 232 fits against the first mating surface 222. This allows the second tool 230 to adaptively align with the first tool 220, eliminating tool alignment errors and ensuring the tool alignment accuracy of the current collector processing device 200, so as to form a more uniform mesh structure 21 on the metal mesh.

[0054] It is understandable that after the first tool 220 and the second tool 230 are assembled, there will still be a tool setting error between them. Therefore, the second tool 230 is movably connected to the drive mechanism 250 through the self-aligning bearing 261 and the elastic support assembly, so that the second tool 230 can adapt to the tool setting with the first tool 220 and eliminate the tool setting error.

[0055] In one embodiment, the first mating surface 222 and the second mating surface 232 are arranged in parallel. Therefore, during the process of the driving mechanism 250 driving the second cutter 230 to move relative to the first cutter 220, the movement of the second cutter 230 relative to the first cutter 220 will generate movement error, thereby affecting the tool setting accuracy of the second cutter 230 relative to the first cutter 220.

[0056] By using the self-aligning bearing 261, the second tool 230 can be fixed relative to the drive mechanism 250 in a plane parallel to the first mating surface 222, but can move in a pitching motion around the self-aligning bearing 261, thereby eliminating the error in guiding the movement between the second mating surface 232 and the first mating surface 222. Simultaneously, the elastic support assembly makes point contact with the bottom of the second tool 230, facilitating the pitching movement of the second tool 230 and helping to eliminate movement errors. This ensures the tool setting accuracy between the second tool 230 and the first tool 220, resulting in a more uniform mesh structure 21 on the metal mesh.

[0057] Specifically, lubricating oil can be filled between the first mating surface 222 and the second mating surface 232 to reduce the friction between them and increase the adaptability of the second mating surface 232 to the first mating surface 222.

[0058] In one embodiment, the adaptive structure 260 further includes a connecting frame, which includes a first frame 263 located on the side of the second tool 230 and a second frame 264 located at the bottom of the second tool 230. Two second frames 264 are provided and are respectively provided on both sides of the first frame 263. Two sets of elastic support components are provided and are respectively provided on the second frames 264. The first frame 263 is movably connected to the side of the second tool 230 through a self-aligning bearing 261. The elastic support components are provided on the second frames 264 and are located between the bottom of the second tool 230 and the second frame 264.

[0059] With this configuration, the self-aligning bearing 261 can support the second tool 230 to be fixed relative to the drive mechanism 250 in a plane parallel to the first mating surface 222, but can pitch around the self-aligning bearing 261, thereby eliminating the error in guiding the movement between the second mating surface 232 and the first mating surface 222.

[0060] Meanwhile, with this arrangement, the elastic support components are symmetrically arranged on both sides of the second cutter 230, which can ensure the reliability of the support of the elastic support components. The elastic support components can make point contact with the bottom of the second cutter 230, which facilitates the pitching movement of the second cutter 230 and helps to eliminate movement errors, thereby ensuring the tool setting accuracy between the second cutter 230 and the first cutter 220, so as to form a more uniform mesh structure 21 on the metal mesh.

[0061] Of course, in other embodiments, the elastic support components may be provided in three, four or more groups, with each group of elastic support components spaced apart along the second direction, and used to abut against the second tool 230 and the first tool 220 for tool alignment.

[0062] In one embodiment, the adaptive structure 260 further includes a connecting rod. The outer ring of the self-aligning bearing 261 is fixed to the second cutter 230. One end of the connecting rod is fixed to the first frame 263, and the other end is in clearance fit with the inner ring of the self-aligning bearing 261, so that the inner ring can slide along the axial direction of the connecting rod. With this arrangement, in the plane perpendicular to the axis of the connecting rod, i.e., in the plane where the first mating surface 222 is located, the self-aligning bearing 261 can support the second cutter 230 to be fixed relative to the drive mechanism 250 in the plane parallel to the first mating surface 222. However, the second cutter 230 can pitch around the self-aligning bearing 261 and slide along the axial direction of the connecting rod, thereby eliminating the error in guiding the movement between the second mating surface 232 and the first mating surface 222.

[0063] Specifically, multiple self-aligning bearings 261 are provided and spaced apart along the side of the second cutter 230 to ensure the stability and reliability of the movable connection. Specifically, two self-aligning bearings 261 are provided. Of course, in other embodiments, the number of self-aligning bearings 261 can be three or more as needed.

[0064] In one embodiment, the elastic support assembly includes a support member 262 and an elastic member 265. A mounting groove 266 is provided on the second frame 264. The elastic member 265 is accommodated within the mounting groove 266 and elastically connected to the support member 262, enabling the support member 262 to be pushed to abut against the bottom of the second tool 230. The elastic member 265 allows the support member 262 to elastically abut against the bottom of the second tool 230, facilitating the pitching movement of the second tool 230 to eliminate movement errors during tool setting.

[0065] In this embodiment, the adaptive structure 260 further includes a gasket 267 and an abutment 268. The gasket 267 is housed in the mounting groove 266, and the elastic member 265 elastically abuts against the gasket 267 and the support member 262. The abutment 268 passes through the second frame 264 and is threadedly connected to the second frame 264. The abutment 268 extends into the mounting groove 266 and abuts against the gasket 267. With this configuration, operating the abutment 268 can adjust the elasticity of the elastic member 265, thereby adjusting the strength of the elastic abutment between the support member 262 and the bottom of the second tool 230. This ensures that the second mating surface 232 of the second tool 230 and the first mating surface 222 of the first tool 220 are tightly fitted with a preload, thus ensuring the tool setting accuracy of the second tool 230 and the first tool 220.

[0066] Specifically, the support member 262 is a bullseye bearing, and each group of elastic support components is provided with multiple elastic support components to ensure the stability and reliability of the elastic support for the second tool 230. Specifically, each group of elastic support components is provided with two elastic support components. Of course, in other embodiments, the number of elastic support components can be three or more as needed.

[0067] In one embodiment, please refer to Figures 8 to 15The current collector processing device 200 also includes a feeding mechanism 240; the feeding mechanism 240 is mounted on the frame 210 and is used to convey the coil material 20 into the cutting space formed by the second cutter 230 and the first cutter 220; the driving mechanism 250 includes a first driving assembly 251 and a second driving assembly 252; the first driving assembly 251 is mounted on the frame 210 and connected to the second driving assembly 252, and the second driving assembly 252 is connected to the second cutter 230. One of the first driving assembly 251 and the second driving assembly 252 is used to drive the second cutter 230 to reciprocate along a straight line in a first direction, and the other is used to drive the second cutter 230 to reciprocate along a straight line in a second direction, so as to process the coil material 20 in the cutting space into a metal mesh. The first direction and the second direction are set at an angle; wherein, the first cutting edge 221 of the first cutter 220 is a flat edge, and the second cutting edge 231 of the second cutter 230 is toothed. The first cutting edge 221 of the first cutter 220 and the second cutting edge 231 of the second cutter 230 both extend along the second direction.

[0068] Figure 8 and Figure 10 The middle arrow X points in the first direction, and the arrow Y points in the second direction.

[0069] It is understandable that by setting the staggered movement of the first cutter 220 and the second cutter 230, the material utilization rate of the roll 20 can be improved, while reducing the mesh size and wire diameter, thereby improving the forming quality of the metal mesh. In this embodiment, the first cutter 220 and the second cutter 230 process the roll 20 without generating cutting waste. The metal mesh is formed by punching and deforming holes in the roll 20 with the cutters, rather than by cutting away the metal sheets inside the mesh structure 21. Therefore, the roll 20 has a high utilization rate and low cost.

[0070] Specifically, both the first drive assembly 251 and the second drive assembly 252 are linear motors; wherein, the first drive assembly 251 is used to drive the second tool 230 to reciprocate along the straight line in the first direction, and the second drive assembly 252 is used to drive the second tool 230 to reciprocate along the straight line in the second direction, thereby realizing the tool setting movement of the second tool 230 relative to the first tool 220.

[0071] Of course, in other embodiments, the first drive assembly 251 may include a first rotary motor, a first lead screw, and a first nut. The first nut is sleeved on the first lead screw and threadedly connected to it. The first rotary motor is connected to the first lead screw and is used to drive the first lead screw to rotate. The second drive assembly 252 may include a second rotary motor, a second lead screw, a second nut, and a moving plate. The moving plate is fixed to the first nut. The second nut is sleeved on the second lead screw and threadedly connected to it. The second rotary motor is connected to the second lead screw and is used to drive it to rotate. The second cutter 230 is connected to the second nut, thereby realizing the tool-setting movement of the second cutter 230 relative to the first cutter 220. However, compared with the linear motor solution, the combination of the rotary motor and the lead screw and nut drive mechanism 250 has a more complex structure and a higher failure rate.

[0072] In one embodiment, the feeding mechanism 240 is used to transport the roll material 20 within the cutting space along a third direction, which is set at an angle to the first and second directions, thereby realizing the transport and processing of the roll material 20. Specifically, the third direction may be perpendicular to the first and second directions.

[0073] Figures 17 to 19 The middle arrow Z points to the third direction. As the feeding mechanism 240 conveys the roll 20 along the third direction, the driving mechanism 250 drives the second cutter 230 to move relative to the first cutter 220 once, forming a row of mesh structures 21 on the roll 20. At this time, the mesh structure 21 is triangular, as shown in the image. Figure 17 As shown, next, as the feeding mechanism 240 continues to move the roll 20 along a third direction, the drive mechanism 250 drives the second cutter 230 to move relative to the first cutter 220 again, and forms another row of mesh structures 21 on the roll 20. At this time, the first row of mesh structures 21 is stretched into a prismatic shape, and the second row of mesh structures 21 is triangular, as shown. Figure 18 As shown, by repeating the above actions, the roll material 20 is processed into various shapes, such as... Figure 19 As shown.

[0074] Figure 20 and Figure 21 These are schematic diagrams showing the tool setting of the first cutting tool 220 and the second cutting tool 230, respectively. Figure 20 The diagram shows the movement of the second cutting edge 231 of the second cutter 230 away from the first cutting edge 221 of the first cutter 220. At this time, there is a gap between the second cutting edge 231 of the second cutter 230 and the first cutting edge 221 of the first cutter 220, allowing the metal mesh to pass through. Figure 21The diagram shows the second cutting edge 231 of the second cutter 230 moving close to the first cutting edge 221 of the first cutter 220. At this time, the second cutting edge 231 of the second cutter 230 and the first cutting edge 221 of the first cutter 220 partially overlap, that is, the toothed second cutting edge 231 and the flat first cutting edge 221 partially overlap, but the coil 20 has not yet been cut, thereby punching holes and deforming the coil 20 to form a mesh structure 21.

[0075] In one embodiment, the first cutting edge 221 of the first cutter 220 is a flat edge, and the second cutting edge 231 of the second cutter 230 is toothed. With this configuration, the opposing motion of the first cutter 220 and the second cutter 230 can cut and punch the roll material 20 to form a mesh structure 21.

[0076] In this embodiment, the first cutting edge 221 of the first cutter 220 and the second cutting edge 231 of the second cutter 230 both extend along the second direction, so that the first cutter 220 and the second cutter 230 can move in a staggered direction parallel to their cutting edges, which facilitates the improvement of the material utilization rate of the roll 20, while reducing the mesh size and wire diameter.

[0077] Specifically, the first cutting edge 221 of the first cutting tool 220 and the second cutting edge 231 of the second cutting tool 230 both extend in the horizontal direction. The first direction and the second direction are set perpendicularly and are both parallel to the horizontal direction. This arrangement facilitates the tool-setting movement of the first cutting tool 220 and the second cutting tool 230 through the drive mechanism 250.

[0078] In one embodiment, please refer to Figures 2 to 9 The current collector processing device 200 also includes a leveling structure 270; the leveling structure 270 includes an adjusting frame 271, a rotating shaft 272, and an adjusting component 273. The first cutting tool 220 is disposed on the adjusting frame 271. The adjusting frame 271 includes a rotating end and an adjusting end disposed opposite to each other. The rotating end is rotatably connected to the frame 210 through the rotating shaft 272, so that the adjusting frame 271 can drive the first cutting tool 220 to rotate around the axis of the rotating shaft 272. The adjusting component 273 is installed on the frame 210 and is used to adjust the position of the adjusting end relative to the frame 210, so that the first cutting edge 221 of the first cutting tool 220 is parallel to the second cutting edge 231 of the second cutting tool 230, thereby ensuring the tool setting accuracy of the current collector processing device 200, so as to form a more uniform mesh structure 21 on the metal mesh.

[0079] In one embodiment, the frame 210 is provided with a first rotating hole 211, and the adjusting frame 271 is provided with a second rotating hole 2711 corresponding to the first rotating hole 211. One end of the rotating shaft 272 is housed in the first rotating hole 211 and the other end is housed in the second rotating hole 2711, so as to rotatably connect the adjusting frame 271 and the frame 210, thereby using one end of the adjusting frame 271 as a rotating shaft.

[0080] Furthermore, in this embodiment, the frame 210 is also provided with a first fixing hole 212, and the adjusting frame 271 is also provided with a first adjusting hole 2712 corresponding to the first fixing hole 212. The first adjusting hole 2712 extends in a strip or arc shape; with such a setting, it can be adapted to the arc rotation of the adjusting frame 271.

[0081] Specifically, the current collector processing device 200 also includes a first adjusting member 274, a first adjusting hole 2712 passing through any position of the first adjusting hole 2712 and detachably connected to the first fixing hole 212, so as to facilitate fixing and locking the adjusted adjusting frame 271 on the frame 210, thereby ensuring the positional accuracy of the first tool 220.

[0082] Specifically, the adjustment component 273 includes an elastic module 2731 and an adjustment module. The elastic module 2731 and the adjustment module are respectively disposed on both sides of the adjustment end. The elastic module 2731 is mounted on the frame 210 and elastically connected to the adjustment end. The adjustment module is mounted on the frame 210 and is used to abut against the adjustment end as it moves closer to the elastic module 2731, causing the elastic module 2731 to compress elastically. With this configuration, the adjustment module can adjust the rotational position of the adjustment frame 271 relative to the frame 210, thereby driving the first cutting edge 221 of the first tool 220 to be parallel to the second cutting edge 231 of the second tool 230, thus ensuring the tool setting accuracy of the current collector processing device 200, so as to form a more uniform mesh structure 21 on the metal mesh.

[0083] It is understandable that after the adjustment module releases the adjustment frame 271, the adjustment frame 271 can be reset under the elastic force of the elastic module 2731, thereby flexibly adjusting the rotational position of the adjustment frame 271 relative to the frame 210.

[0084] Furthermore, the adjustment module is an electrically adjustable module, while the manually adjustable module includes a fixed block 2732, a movable block 2733, an adjusting rod 2734, and a handwheel 2735. The fixed block 2732 is mounted on the frame 210 and has a threaded hole. The adjusting rod 2734 passes through the threaded hole and is threadedly connected to the fixed block 2732. The handwheel 2735 is located at the end of the adjusting rod 2734. Rotating the handwheel 2735 drives the adjusting rod 2734 to rotate, causing the adjusting rod 2734 to push the movable block 2733 against the adjusting end and move it closer to the elastic module 2731. With this configuration, a screw and nut adjustment structure can be used to move the position of the movable block 2733, thereby adjusting the rotational position of the adjusting frame 271 relative to the frame 210.

[0085] In this embodiment, in order to further improve the leveling accuracy of the first cutting edge 221 of the first tool 220 and the second cutting edge 231 of the second tool 230, the fixed block 2732 is provided with a first inclined surface 2736 on the side opposite to the moving block 2733, and the moving block 2733 is provided with a second inclined surface 2737 on the side opposite to the fixed block 2732. The first inclined surface 2736 and the second inclined surface 2737 are slidably engaged. The adjusting rod 2734 is provided with a pushing block 2738. The pushing block 2738 abuts against the moving block 2733, which moves so that the moving block 2733 slides relative to the fixed block 2732 along the extension trajectory of the first inclined surface 2736, and moves the moving block 2733 against the adjusting end close to the elastic module 2731. With this configuration, based on the adjustment accuracy of each thread in the thread structure, the cooperation of the first inclined surface 2736 and the second inclined surface 2737 can be introduced to further improve the displacement accuracy of the moving block 2733, thereby increasing the rotational position accuracy of the adjusting frame 271 relative to the frame 210. Therefore, it can be further ensured that the first cutting edge 221 of the first tool 220 and the second cutting edge 231 of the second tool 230 are parallel, thereby ensuring the tool setting accuracy of the current collector processing device 200, so as to form a more uniform mesh structure 21 on the metal mesh.

[0086] Specifically, the manual adjustment module also includes a roller 2739, which is rotatably connected to the adjustment end and rolls with the moving block 2733. This changes the surface fit between the moving block 2733 and the adjustment frame 271 to a rolling fit, thereby improving the smoothness and accuracy of leveling the first cutting edge 221 of the first tool 220 and the second cutting edge 231 of the second tool 230.

[0087] Of course, in other embodiments, the adjustment module can also be an electric adjustment module, which includes a fixed block, a moving block, an adjustment rod, and an adjustment motor. The fixed block is mounted on the frame and has a threaded hole. The adjustment rod passes through the threaded hole and is threadedly connected to the fixed block. The adjustment motor is driven by the adjustment rod and is used to drive the adjustment rod to rotate so that the adjustment rod pushes the moving block to abut against the adjustment end and move closer to the elastic module. Compared with the manual adjustment module, the electric adjustment module has higher adjustment accuracy, but the cost will also increase. Furthermore, the adjustment motor can be a servo motor or a stepper motor.

[0088] In one embodiment, the frame 210 is further provided with a second fixing hole 213, and the adjusting frame 271 is further provided with a second adjusting hole 2713 corresponding to the second fixing hole 213. The second adjusting hole 2713 extends in a strip or arc shape; with such a configuration, it can accommodate the arc rotation of the adjusting frame 271.

[0089] Specifically, the current collector processing device 200 also includes a second adjusting member 275, and a second adjusting hole 2713 is provided at any position of the second adjusting hole 2713 and is detachably connected to the second fixing hole 213, so as to facilitate the fixing and locking of the adjusted adjusting frame 271 on the frame 210, thereby ensuring the positional accuracy of the first tool 220.

[0090] Please see Figures 1 to 21 This utility model embodiment also discloses a battery current collector production equipment, which includes the current collector processing device 200 of any of the above embodiments.

[0091] Understandably, because the second tool 230 in the current collector processing device 200 can adaptively align with the first tool 220, eliminating tool alignment errors, the tool alignment accuracy of the current collector processing device 200 is ensured, resulting in a more uniform mesh structure 21 on the metal mesh, thereby improving the forming quality of the metal mesh. Applying the above-mentioned current collector processing device 200 to battery current collector production equipment can increase the product quality of the current collector.

[0092] Please see Figure 1 The battery current collector production equipment also includes a winding device 100, which is used to wind up the metal mesh processed by the current collector processing device 200.

[0093] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
