In order to meet different battery design and production requirements, aluminum foil needs to be accurately sheared. However, the existing aluminum foil shearing device has some shortcomings.

[0003] When a traditional shearing device processes aluminum foil, due to the lack of effective cleaning measures, dust or debris may remain on the surface of the aluminum foil. If these impurities are not removed during the shearing process, the aluminum foil will be squeezed by the conveying roller during transportation, causing dents on the surface of the aluminum foil, affecting the quality of the final product.

The driving mechanism 3 includes a driving motor 301, a first transmission shaft 302, a second transmission shaft 401, a first rotating disk 303 and a connecting rod 304; The sharpening mechanism 5 includes a first slide plate 501, a second slide plate 502, a first rotating shaft 503, a third gear 5031, a rack 504, a second turntable 505, a limit frame 506, a first grinding block 507 and a second grinding block 508. A knife drop hole 2022 is provided at the center of the pressure plate 202, and the sharpening mechanism 5 is installed in the knife drop hole 2022 to grind the cutter 201.

[0022] Furthermore, a first column 105 is provided on the upper end surface of the processing machine tool 1, and a second transmission shaft 401, a first wiping roller 403, a second wiping roller 404 and a feeding roller 402 are installed on the first column 105 and are rotatably connected thereto; a first synchronous wheel 4012 and a second synchronous wheel 4013 are provided on the second transmission shaft 401; a fourth synchronous wheel 4031 cooperating with the first synchronous wheel 4012 is provided on the first wiping roller 403; a second synchronous belt 406 for transmission is provided on the first synchronous wheel 4012 and the fourth synchronous wheel 4031; a third synchronous wheel 4021 cooperating with the second synchronous wheel 4013 is provided on the feeding roller 402; a first synchronous belt 405 for transmission is sleeved on the second synchronous wheel 4013 and the third synchronous wheel 4021; a first gear 4032 is provided on the first wiping roller 403; and a second gear 4041 meshing with the first gear 4032 is provided on the second wiping roller 404.

[0023] The first wiping roller 403 and the second wiping roller 404 are driven to rotate by the second transmission shaft 401, so as to wipe off the dust or debris that may exist on the surface of the aluminum foil, and avoid dents on the surface of the aluminum foil when the feed roller 402 is rolling. At the same time, the second transmission shaft 401 also drives the feed roller 402 to rotate, so that the feed roller 402 rolls the filter plate flat and sends the aluminum foil to the shearing mechanism 2 at the same time.

[0024] Furthermore, the surfaces of the first wiping roller 403 and the second wiping roller 404 are provided with wiping cotton 4033, which is made of sponge wrapped with microfiber. The wiping cotton 4033 is attached to the outer end surfaces of the first wiping roller 403 and the second wiping roller 404 by Velcro, and the bottom of the first wiping roller 403 and the top of the second wiping roller 404 are fitted together.

[0025] The two sets of wiping rollers wipe off the floating dust on the upper and lower ends of the aluminum foil and other impurities that may adhere to its surface during transportation, thereby improving the surface finish of the aluminum foil and avoiding pits on the surface of the aluminum foil when the subsequent feeding roller 402 rolls on it. The wiping cotton 4033 made of microfiber wrapped sponge has good elasticity and can fit the aluminum foil without causing scratches. The detachable structure facilitates the removal of the wiping cotton 4033 for cleaning or replacement.

[0026] Furthermore, the feed roller 402 is a cylindrical structure, and an intermittent groove 4022 is provided on the side of the feed roller 402. The intermittent groove 4022 is a fan-shaped groove, and the edge of the intermittent groove 4022 is chamfered. The feed roller 402 is made of rubber, and the feed roller 402 is in contact with the upper end surface of the processing table 101.

[0027] When the feed roller 402 contacts the aluminum foil, the feed roller 402 drives the aluminum foil to slide forward, thereby sending the aluminum foil to the lower end of the shearing mechanism 2. When it rotates to the intermittent groove 4022, the aluminum foil no longer slides forward, and the pressure plate 202 just presses the aluminum foil, and the cutter 201 moves downward to perform the shearing action. After the shearing is completed, the feed roller 402 feeds again to prepare for the next shearing action.

[0028] Furthermore, the drive motor 301 is fixedly mounted on the bottom upper end surface of the processing table 101, the output shaft of the drive motor 301 is provided with a first sprocket 3011 and a second sprocket 3012, the second transmission shaft 401 is provided with a fourth sprocket 4011 matched with the first sprocket 3011, the first sprocket 3011 and the fourth sprocket 4011 are provided with a second chain 306 for transmission, the first transmission shaft 302 is installed in the processing table 101 and is rotatably connected thereto, and the first transmission shaft 302 is provided with a second chain 306 for transmission. The third sprocket 3021 cooperates with the wheel 3012, and the first chain 305 for transmission is sleeved on the second sprocket 3012 and the third sprocket 3021. The first turntable 303 is fixedly installed on the first transmission shaft 302. The side of the first turntable 303 is provided with a first eccentric shaft 3031, and the bottom of the connecting rod 304 is sleeved on the first eccentric shaft 3031 and is rotatably connected to it. The side of the cutter 201 is provided with a third rotating shaft 2012, and the top of the connecting rod 304 is sleeved on the third rotating shaft 2012 and is rotatably connected to it.

[0029] The driving motor 301 drives the first transmission shaft 302 and the second transmission shaft 401 to rotate through the sprocket and the chain. During the rotation of the first turntable 303 on the side of the first transmission shaft 302, the first eccentric shaft 3031 on its side pulls the connecting rod 304 back and forth, thereby driving the cutter 201 to slide back and forth along the slide rail 108 under the cooperation of the slider 109 and the slide rail 108 to complete the shearing of the aluminum foil. The second transmission shaft 401 drives the feed roller 402, the first wiping roller 403 and the second wiping roller 404, so that the driving motor 301 completes the overall driving of the equipment.

[0030] Furthermore, a first guide rod 2021 is provided on the upper end surface of the pressure plate 202, a first guide hole 2011 slidably matched with the first guide rod 2021 is provided on the upper end surface of the cutter 201, a compression spring 203 is sleeved on the first guide rod 2021, and a limiting portion is provided on the top of the first guide rod 2021.

[0031] The cutting knife 201 drives the pressing plate 202 to slide down during the sliding process, and the aluminum foil is pressed and fixed in advance. After the fixing is completed, the cutting knife 201 continues to slide down to drive the aluminum foil, thereby improving the uniformity of cutting. After the cutting is completed, the pressing plate 202 is separated from the cutting knife 201 under the reset action of the compression spring 203. The cutting knife 201 generates two relative displacements with the pressing plate 202 during one cutting process, thereby triggering the sharpening mechanism 5 twice.

[0032] Furthermore, the first rotating shaft 503 is installed in the knife hole 2022 and is rotatably connected to the pressure plate 202. The inner wall of the knife hole 2022 is provided with a shaft seat 509 that matches the first rotating shaft 503. The third gear 5031 is fixedly installed on the first rotating shaft 503.

The first slide plate 501 and the second slide plate 502 are provided with a plurality of rotating disks 505, 506, 57, 58, 59, 60, 71, 62, 64, 65, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 101, 102, 110, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135 Installed in the knife hole 2022, the first slide 501 and the second slide 502 are respectively located at the front and rear sides of the cutter 201, and the left and right sides of the first slide 501 and the second slide 502 are provided with a second guide rod 5011 slidingly connected to the pressure plate 202. The limit frame 506 is fixedly installed on the second guide rod 5011. The limit frame 506 is a rounded rectangular structure. The limit frame 506 is provided with a third slide groove 5061 that cooperates with the second eccentric shaft 5051. The second eccentric shaft 5051 passes through the limit frame 506 and is movably connected to it.

[0033] When the cutter 201 is pressed down for shearing and reset, the third gear 5031 cooperates with the rack 504 to drive the first rotating shaft 503 to rotate, so that the second rotating disk 505 on both sides of the first rotating shaft 503 drives the second eccentric shaft 5051 to rotate, so that the second eccentric shaft 5051 pulls the first slide plate 501 and the second slide plate 502 back and forth, so that the first grinding block 507 and the second grinding block 508 on the surface of the first slide plate 501 and the second slide plate 502 rub back and forth on the blade of the cutter 201, and cooperate with the up and down sliding of the cutter 201 to achieve comprehensive grinding of the blade surface and improve the sharpness of the blade.

[0034] Furthermore, the first grinding block 507 is fixedly mounted on the side of the second slide plate 502, a second rotating shaft 50811 is arranged on the side of the second grinding block 508, a torsion spring 5084 is arranged on the second rotating shaft 50811, an ear plate 5012 cooperating with the second rotating shaft 50811 is arranged on the first slide plate 501, the second grinding block 508 is elastically rotatably connected to the first slide plate 501 through the torsion spring 5084 and the second rotating shaft 50811, and a limit plate 5085 for limiting its rotation angle is arranged on the top of the second grinding block 508.

[0035] One side of the bottom of the cutter 201 is a bevel structure, and the other side is a plane structure. The first grinding block 507 is fixedly connected so that it can fit with the plane side of the cutter 201. The rotatably connected second grinding block 508 can fit with the bevel side of the cutter 201, and when the cutter 201 is pressed down, it can flip outward without affecting the cutter 201 from falling for cutting. The limit block limits the rotation angle of the first grinding block 507 to prevent its rotation angle from being too large and interfering with the movement of the cutter 201.

[0036] Furthermore, the first grinding block 507 and the second grinding block 508 include a base 5081, a grinding stone 5082 and a corrugated spring 5083. A first slide groove 50812 is arranged on the side of the base 5081. The grinding stone 5082 is installed in the first slide groove 50812 and is elastically slidably connected to the base 5081 through the corrugated spring 5083. Corrugated ridges are arranged on the side of the grinding stone 5082, and the upper end surface of the grinding stone 5082 is a slope structure.

[0037] The elastically connected grinding stone 5082 can still keep in contact with the blade of the cutter 201 after being consumed and thinned, thereby improving the service life of the grinding stone 5082. The corrugated cam enhances the surface roughness of the grinding stone 5082 and increases the heat dissipation area of ​​the grinding stone 5082, further improving the grinding effect. The top is set as a slope structure, so that the grinding stone 5082 can be pressed into the first slide groove 50812 when the cutter 201 falls, avoiding interference with the movement of the cutter 201.

[0038] When using this equipment: first check whether all parts of the equipment are intact, ensure that the parts of the feeding mechanism 4, the shearing mechanism 2, the sharpening mechanism 5 and the driving mechanism 3 are not damaged or loose, and that all transmission parts operate flexibly, install the aluminum foil roll on the unwinding roller 102 of the processing machine 1, ensure that the starting end of the aluminum foil can be smoothly led out, and pass around the roller 103 and the guide wheel 104 in turn, so that the aluminum foil remains flat and properly tensioned, and avoids wrinkles or looseness of the aluminum foil during the feeding process, thereby affecting the cutting quality and feeding stability, turn on the drive motor 301, and the drive motor 301 drives the first transmission shaft 302 and the second transmission shaft 401 to rotate through the first sprocket 3011 and the second sprocket 3012 on the output shaft, and the corresponding first chain 305 and the second chain 306. As the second transmission shaft 401 rotates, the first wiping roller 403, the second wiping roller 404 and the feeding roller 402 start to work. The first wiping roller 403 and the second wiping roller 404 clean the upper and lower surfaces of the aluminum foil through the wiping cotton 4033 on the surface to remove possible dust and debris. At the same time, the feeding roller 402 starts to drive the aluminum foil to move toward the shearing mechanism 2; When the aluminum foil is conveyed to the bottom of the shearing mechanism 2 by the feeding roller 402, the driving motor 301 drives the first rotating disk 303 on the first transmission shaft 302 to rotate, and the first eccentric shaft 3031 on the side of the first rotating disk 303 pulls the third rotating shaft 2012 on the side of the cutter 201 through the connecting rod 304, so that the cutter 201 moves downward along the slide rail 108 under the cooperation of the slider 109 and the slide rail 108. During the downward pressing process of the cutter 201, the pressing plate 202, driven by the cutter 201, presses and fixes the aluminum foil in advance through the action of the first guide rod 2021 and the compression spring 203 to prevent the aluminum foil from shifting during cutting. The cutter 201 continues to press down to complete the cutting action of the aluminum foil. After the cutting is completed, the pressing plate 202 is separated from the cutter 201 under the resetting action of the compression spring 203, and the cutter 201 is pulled upward by the connecting rod 304 to prepare for the next cutting. During each downward pressing and resetting process of the cutter 201, the rack 504 on the side of the cutter 201 will drive the third gear 5031 on the first rotating shaft 503 to rotate, thereby causing the second turntable 505 on both sides of the first rotating shaft 503 to rotate, and the second eccentric shaft 5051 on the second turntable 505 will reciprocate the first slide plate 501 and the second slide plate 502, so that the first grinding block 507 and the second grinding block 508 installed on the first slide plate 501 and the second slide plate 502 will reciprocate on the blade of the cutter 201 to rub, thereby realizing automatic grinding of the cutter 201. Example 2

[0039] See also Figure 1-Figure 13 A shearing method for battery aluminum foil is applicable to a shearing device for battery aluminum foil, comprising the following steps: Step 1, loading. Before loading, first conduct a comprehensive inspection of the equipment to ensure that the surfaces of the unwinding roller 102, rotating roller 103, first wiping roller 403, second wiping roller 404 and feeding roller 402 are clean and free of debris, and that the rotating shafts of each roller are flexible and free of jamming. At the same time, check whether the cutter 201 is installed firmly, whether the blade is intact, whether the sharpening mechanism 5 is in normal condition, whether the connection of each transmission component is tight, and carefully install the aluminum foil coil on the unloading roller 102. Pay attention to make the center hole of the aluminum foil coil and the axis of the unloading roller 102 fit tightly to prevent the coil from deflecting or shaking during the feeding process. The center axis of the unloading roller 102 is rotatably connected to the outer roller through a damping bearing, so that the friction force of the wiping roller is not enough to pull the aluminum foil belt. Then, slowly lead the aluminum foil from the coil so that it passes through the upper end surface of the rotating roller 103. Then, pass the aluminum foil through the gap between the first wiping roller 403 and the second wiping roller 404. At this time, pay attention to adjust the position of the aluminum foil so that it is located at the center of the wiping roller so that impurities on the upper and lower surfaces of the aluminum foil can be effectively wiped off. Finally, the aluminum foil is passed through the lower end surface of the feeding roller 402, and it is ensured that the aluminum foil is closely attached to the feeding roller 402, and the front end of the aluminum foil is sent to the lower side of the cutter 201, and it is ensured that the aluminum foil is in a straight state without wrinkles or curling; Step 2, start the equipment. Before turning on the drive motor 301, confirm again that no one is close to the equipment, no foreign objects are blocking the components, and the power cord of the motor is firmly connected and not damaged. After starting the drive motor 301, the output shaft of the motor starts to rotate, and the power is transmitted to the first transmission shaft 302 and the second transmission shaft 401 through the first sprocket 3011 and the second sprocket 3012 thereon, and the corresponding first chain 305 and the second chain 306. In this process, the transmission of the chain should be closely observed to ensure that the chain runs smoothly on the sprocket without jumping, falling off or jamming. At the same time, monitor the running sound of the motor and each transmission shaft to determine whether there is any abnormal noise. If there is any abnormality, stop the machine immediately for inspection. With the rotation of the first transmission shaft 302 and the second transmission shaft 401, the turntable, connecting rod 304 and other components in the driving mechanism 3 begin to work together, thereby driving the feeding roller 402 of the feeding mechanism 4 and the cutter 201 of the shearing mechanism 2 to move according to a predetermined rhythm and trajectory. At this time, pay attention to observe the initial movement state of the feeding roller 402 and the cutter 201 to ensure that their movement direction is correct, the stroke is normal, and the coordination between the various components is smooth; Step 3, wiping the aluminum foil. When the driving mechanism 3 drives the second transmission shaft 401 to rotate, the first wiping roller 403 and the second wiping roller 404 installed on the first column 105 start to rotate synchronously. The surfaces of the first wiping roller 403 and the second wiping roller 404 are tightly fitted, and both are wrapped with wiping cotton 4033 made of ultra-fine fiber wrapped sponge. This wiping cotton 4033 has good adsorption and softness, which can effectively remove the floating dust on the surface of the aluminum foil without scratching the aluminum foil. During the wiping process, pay attention to the cleanliness of the wiping cotton 4033. If it is found that there are too many impurities adsorbed on the wiping cotton 4033, which affects the wiping effect, the wiping cotton 4033 should be replaced in time. Step 4, rolling and feeding. The feed roller 402 is made of rubber, and an intermittent groove 4022 is set on its side, and it fits with the upper end surface of the processing table 101. When the feed roller 402 rotates, the friction between it and the aluminum foil will drive the aluminum foil to move forward, and at the same time, the aluminum foil will be rolled flat. The intermittent groove 4022 on the feed roller 402 is designed so that when the cutter 201 is cutting, the aluminum foil can temporarily stop moving, avoiding the displacement of the aluminum foil during the cutting process, thereby ensuring the cutting accuracy. During the feeding process, pay attention to the feeding speed and tension of the aluminum foil to ensure that the aluminum foil can be uniformly and smoothly fed to the bottom of the shearing mechanism 2. If it is found that the feeding speed of the aluminum foil is uneven or there is slack or tension, check whether the rotation speed of the feed roller 402 is stable, whether the connection of each transmission component is loose, and make corresponding adjustments; Step 5, cutting. The cutter 201 of the shearing mechanism 2 is installed on the slide rail 108 through the slider 109, and is elastically slidably connected to the pressure plate 202 through the compression spring 203. The driving motor 301 drives the first turntable 303 on the first transmission shaft 302 to rotate. The first eccentric shaft 3031 on the side of the first turntable 303 pulls the third shaft 2012 on the side of the cutter 201 through the connecting rod 304, so that the cutter 201 reciprocates up and down along the slide rail 108 under the cooperation of the slider 109 and the slide rail 108, so as to achieve intermittent cutting of the aluminum foil. During the cutting process, the pressure plate 202 will press and fix the aluminum foil in advance when the cutter 201 is pressed down to prevent the aluminum foil from shifting during cutting. After each cutting is completed, the pressure plate 202 is separated from the cutter 201 under the resetting action of the compression spring 203, and the cutter 201 is pulled upward by the connecting rod 304 to prepare for the next cutting. Step 6, sharpening the knife. During the cutting process, the up and down movement of the cutter 201 drives the first shaft 503 to rotate through the meshing of the rack 504 and the third gear 5031, so that the second rotating disks 505 on both sides of the first shaft 503 drive the second eccentric shaft 5051 to rotate, and the second eccentric shaft 5051 reciprocates the first slide plate 501 and the second slide plate 502, so that the first grinding block 507 and the second grinding block 508 installed on the first slide plate 501 and the second slide plate 502 reciprocate on the blade of the cutter 201. The first grinding block 507 and the second grinding block 508 adopt an elastic connection structure, and a first slide groove 50812 is provided on the side of the base 5081. The grinding stone 5082 is installed in the first slide groove 50812 and is elastically slidably connected with the base 5081 through a corrugated spring 5083. This design ensures that the grinding stone 5082 can still keep in contact with the blade of the cutter 201 after being consumed and thinned, thereby extending the service life of the grinding stone 5082.
