Description

Technical Field

[0001] This invention relates to the field of battery pack manufacturing technology, and in particular to a hand-tearable steel uncoiling device for the production of new energy battery packs. Background Technology

[0002] With the explosive growth of the global new energy vehicle and energy storage industries, the demand for high-energy-density and high-safety power batteries continues to rise. Hand-tearable steel (ultra-thin stainless steel foil), with its excellent corrosion resistance, high strength, high-temperature resistance, and lightweight advantages, is gradually replacing traditional aluminum foil as the core packaging material for next-generation power batteries. It is widely used in the tabs, current collectors, and battery casing shielding layers of lithium iron phosphate batteries, ternary lithium batteries, and solid-state batteries. Uncoiling is the first critical process in the processing and production of hand-tearable steel; its operational stability and precision directly determine the product quality and production efficiency of subsequent processes such as slitting, coating, stamping, and welding.

[0003] However, due to its extremely thin thickness, low stiffness, and susceptibility to deformation and breakage, hand-tearable steel is prone to lateral drift, serpentine movement, or localized wrinkling during high-speed uncoiling and tension fluctuations. Traditional web-aligning systems suffer from slow response times and insufficient control precision, leading to deviations in the strip as it enters subsequent processes. This not only increases the risk of strip breakage and scratches but also causes poor edge alignment in subsequent slitting or coating processes, impacting yield and material utilization. Summary of the Invention

[0008] Preferably, the correction assembly further includes a displacement amplifier movably mounted on the mounting frame and a roller rotatably connected to the displacement amplifier.

The first flattening plate is fixed inside the placement groove, and the second flattening plate is rotatably connected inside the placement groove by a torsion spring. The surface of the second flattening plate has an oblique vent hole, and the surface of the first flattening plate has a vertical vent hole.

[0012] Preferably, the oblique exhaust holes are arranged in an array on the surface of the second flat plate, the mounting bracket has a connecting hole inside that communicates with the second flat plate, a guide plate is fixed on the lower surface of the mounting bracket, the connecting hole is connected to the guide plate, an air inlet pipe is fixed on one side of the guide plate, the other end of the air inlet pipe is connected to an external air source device, a connecting pipe is fixed on the side of the guide plate, the upper end of the connecting pipe passes through the interior of the first flat plate, the vertical exhaust holes are connected to the guide plate through the connecting pipe, the vertical exhaust holes are evenly distributed on the surface of the first flat plate, and the diameter of the vertical exhaust holes is the same as the diameter of the oblique exhaust holes.

[0013] Preferably, a second connecting rod is hinged to the lower surface of the second display plate, a pull rod is provided inside the placement groove, the lower end of the second connecting rod is hinged to the upper surface of the pull rod, the other end of the pull rod passes through the placement groove and extends to the outside of the mounting bracket, and the other end of the pull rod is fixed to the side of the connecting plate.

[0014] Preferably, the uncoiler includes a drive unit and a guide roller fixed on the worktable. The output end of the drive unit is fixed with an installation unit. The guide roller is disposed on one side of the installation unit, and a flexible buffer layer is provided on the outer peripheral surface of the guide roller.

[0015] Preferably, a telescopic rod is fixed on the installation unit, a top plate is fixed to the output end of the telescopic rod, a spring is sleeved on the outer periphery of the telescopic rod, and the two ends of the spring are respectively fixed to the installation unit and the top plate. There are multiple sets of telescopic rods and top plates, and the outer surfaces of multiple top plates are arc-shaped surfaces adapted to the inner ring of the hand-tearable steel coil.

[0016] The beneficial effects of this invention are: 1. This invention uses a displacement amplifier to detect and amplify the lateral offset of the hand-torn steel strip in real time, driving the connecting plate to slide the moving rod. Then, the first connecting rod controls the extension or retraction of the correction block on the surface of the transmission roller. At the same time, the correction block is set at an angle, which can apply a lateral force pointing towards the center line to the offset edge of the strip, thereby dynamically correcting the hand-torn steel strip. This avoids the problems of strip serpentine movement and deviation caused by the slow response and insufficient accuracy of traditional correction systems, reduces the risk of strip breakage and scratches, and improves the edge alignment of subsequent processes.

[0017] 2. The present invention enables the compressed air, after being diverted by the guide plate, to form a uniform air film through the vertical exhaust holes of the first spreading plate, reducing the friction between the hand-tearable steel and the plate surface and providing upward support, preventing the strip from sagging or sticking due to its own weight; at the same time, the oblique exhaust holes of the second spreading plate spray airflow with lateral force, which can actively stretch the edge of the strip to both sides, eliminating the transverse wrinkles and wavy unevenness generated during the uncoiling process; in addition, the vertical and oblique exhaust holes have the same diameter, which can avoid strip deformation or shaking caused by local air pressure differences, and improve the flatness of the hand-tearable steel.

[0018] 3. When the connecting plate of the present invention moves under the drive of the displacement amplifier to adjust the correction block, it will synchronously drive the pull rod on the inclined side to move. The second connecting rod pulls the second spreading plate to rotate around the hinge point, thereby dynamically adjusting the angle of the inclined exhaust hole on the inclined side, while the second spreading plate on the opposite side maintains the initial angle. At this time, the airflow ejected from the inclined exhaust hole on the opposite side still applies a strong outward tension to the edge of the strip. Under the action of the tension difference on both sides, the strip will move towards the center line, further improving the correction effect and response speed. Attached Figure Description

Detailed Implementation

[0021] To make the technical problems solved by the invention, the technical solutions and the beneficial effects clearer, the invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0022] The embodiments provided by this invention are as follows: Figures 1-8As shown, a hand-tearable steel uncoiling device for the production of new energy battery packs includes an uncoiling machine 1 and a mounting frame 2 installed on one side of the uncoiling machine 1. The mounting frame 2 is equipped with a correction component 3 and a flattening component 4. The flattening component 4 is located in the middle of the uncoiling machine 1 and the correction component 3. Both the correction component 3 and the flattening component 4 are located in the conveying path of the hand-tearable steel coil and are used to flatten and correct the hand-tearable steel after uncoiling in sequence.

[0023] The correction assembly 3 includes a drive roller 304. A movable groove 201 is formed on the surface of the mounting frame 2. The drive roller 304 is rotatably connected inside the movable groove 201. A drive chamber 305 is formed inside the drive roller 304. A support rod 306 is fixed to the inner wall of the drive chamber 305. A movable rod 307 is sleeved on the outer periphery of the support rod 306. A first connecting rod 308 is hinged to the outer periphery of the movable rod 307. A correction block 309 is hinged to the other end of the first connecting rod 308. The correction block 309 is movably mounted on the drive roller 304. 04. The correction block 309 is arc-shaped, and its upper surface is flush with the circumferential surface of the transmission roller 304. The correction block 309 is made of wear-resistant rubber, and its surface is provided with anti-slip texture. The other end of the moving rod 307 passes through the transmission chamber 305 and extends to the outside of the mounting frame 2. There are multiple sets of correction blocks 309 and first connecting rods 308, which are evenly arranged in a ring on the outer circumferential surface of the moving rod 307. The correction blocks 309 are inclined, and the correction blocks 309... The tilting direction is towards the centerline of the mounting frame 2. The correction assembly 3 also includes a displacement amplifier 303 movably mounted on the mounting frame 2 and a roller 302 rotatably connected to the displacement amplifier 303. The output end of the displacement amplifier 303 is fixed with a connecting plate 313, which is located on one side of the moving rod 307. When the hand-torn steel is laterally offset on the surface of the transmission roller 304 and touches the roller 302, the roller 302 drives the displacement amplifier 303 to produce a small displacement. The displacement amplifier 303 amplifies the displacement signal and drives the connecting plate 313 to move. The connecting plate 313 drives the moving rod 307 to slide axially along the support rod 306. During the sliding process, the moving rod 307 pulls the correction block 309 to extend from the surface of the transmission roller 304 through the first connecting rod 308. Since the correction block 309 is tilted and the tilting direction is towards the centerline of the mounting frame 2, the correction block 309 can apply a lateral force pointing towards the centerline to the offset edge of the hand-torn steel, thereby correcting the hand-torn steel in real time.

[0024] A slider 310 is fixed to the end face of the moving rod 307. A groove corresponding to the slider 310 is opened on the side of the connecting plate 313. The slider 310 moves inside the groove, and both the slider 310 and the groove have a "T" shaped cross section. A tension spring is also fixed to the side of the connecting plate 313, and the other end of the tension spring is fixed to the side of the mounting bracket 2. When the connecting plate 313 moves under the drive of the displacement amplifier 303, the slider 310 slides in the groove, so that the moving rod 307 moves synchronously with the connecting plate 313 during rotation, avoiding motion interference between the moving rod 307 and the connecting plate 313. When the hand-torn steel returns to the center state and no longer touches the roller 302, the tension of the tension spring acts on the connecting plate 313, driving the connecting plate 313 to reset. Then, the correction block 309 is retracted into the transmission roller 304 through the moving rod 307 and the first connecting rod 308, preventing the correction block 309 from continuously extending and interfering with the normal conveying of the hand-torn steel.

[0025] The mounting bracket 2 has a housing 301 fixed to its side, and a rotary motor 311 is fixed to the side of the housing 301. The output end of the rotary motor 311 is fixed with a drive wheel 312, and a driven wheel is fixed to the outer periphery of the transmission roller 304. The drive wheel 312 and the driven wheel are connected by a synchronous belt. The output end of the rotary motor 311 drives the drive wheel 312 to rotate, and the driven wheel rotates synchronously with the drive wheel 312 through the synchronous belt, thereby driving the transmission roller 304 to rotate in the placement groove 202. This allows the hand-torn steel to maintain a stable running speed when passing through the transmission roller 304, improving the stability of the correction effect.

[0026] The flattening assembly 4 includes a first flattening plate 401 and a second flattening plate 402. The mounting bracket 2 has a placement groove 202 on its surface. The first flattening plate 401 is fixed inside the placement groove 202, and the second flattening plate 402 is rotatably connected to the placement groove 202 via a torsion spring. The surface of the second flattening plate 402 has an oblique vent 407, and the surface of the first flattening plate 401 has a vertical vent 406. The vertical vent 406 on the surface of the first flattening plate 401 can eject gas upwards, forming an air film on the lower surface of the hand-tearable steel, reducing tearing. The friction between the steel and the first spreading plate 401, along with the upward thrust of the gas, can lift the thin, hand-tearable steel, preventing it from sagging or sticking to the plate due to its own weight. The oblique exhaust holes 407 on the surface of the second spreading plate 402 spray out gas at a certain angle, which can not only further reduce the friction between the hand-tearable steel and the second spreading plate 402, but also generate a component force outward along the width of the hand-tearable steel, stretching the edges of the hand-tearable steel to both sides, thereby flattening any transverse wrinkles or wavy unevenness that may occur during the uncoiling process.

[0027] The oblique exhaust ports 407 are arrayed on the surface of the second display plate 402. The mounting bracket 2 has connecting holes 203 that communicate with the second display plate 402. A guide plate 405 is fixed to the lower surface of the mounting bracket 2. The connecting holes 203 are connected to the guide plate 405. An air inlet pipe 409 is fixed to one side of the guide plate 405, and the other end of the air inlet pipe 409 is connected to an external air source device. A connecting pipe 408 is fixed to the side of the guide plate 405. The upper end of the connecting pipe 408 passes through the interior of the first display plate 401. Vertical exhaust ports 406 are connected to the guide plate 405 through the connecting pipe 408. The vertical exhaust ports 406 are evenly distributed on the surface of the first display plate 401, and the diameter of the vertical exhaust ports 406 is the same as the diameter of the oblique exhaust ports 407. The external air source device generates... Compressed air enters the guide plate 405 through the intake pipe 409. The guide plate 405 diverts the gas to the connecting hole 203 and the connecting pipe 408. The connecting hole 203 delivers the gas to the interior of the second spreading plate 402, and finally ejects it through the array of oblique exhaust holes 407, ensuring that the flattening force is evenly applied to each area of ​​the tearable steel on the second spreading plate 402. The connecting pipe 408 guides the gas into the interior of the first spreading plate 401, and then ejects it upward through the evenly distributed vertical exhaust holes 406, forming a stable air film support. At the same time, the diameter of the vertical exhaust holes 406 is the same as the diameter of the oblique exhaust holes 407, so that the gas flow rate and pressure ejected from the vertical exhaust holes 406 and the oblique exhaust holes 407 are consistent, thereby avoiding new deformation or vibration of the strip due to local air pressure differences.

[0028] The second display plate 402 has a second connecting rod 403 hinged to its lower surface. A pull rod 404 passes through the placement groove 202. The lower end of the second connecting rod 403 is hinged to the upper surface of the pull rod 404. The other end of the pull rod 404 passes through the placement groove 202 and extends to the outside of the mounting bracket 2. The other end of the pull rod 404 is fixed to the side of the connecting plate 313. When the connecting plate 313 moves under the drive of the displacement amplifier 303, it will synchronously drive the pull rod 404 to slide in the placement groove 202. The pull rod 404 pulls the second display plate 402 to rotate around its hinge point with the placement groove 202 through the second connecting rod 403, thereby adjusting the angle of the oblique exhaust hole 407 opened on the surface of the second display plate 402, thereby assisting the correction component 3 in correction.

[0029] The uncoiler 1 includes a drive unit 101 and a guide roller 103 fixed on a workbench. An installation unit 102 is fixed to the output end of the drive unit 101. The guide roller 103 is disposed on one side of the installation unit 102, and a flexible buffer layer is provided on its outer circumferential surface. The drive unit 101 drives the installation unit 102 to rotate, thereby driving the hand-tearable steel coil mounted on the installation unit 102 to perform an uncoiling operation. The guide roller 103 can guide the uncoiled hand-tearable steel. The flexible buffer layer on its outer circumferential surface can prevent scratches or indentations caused by rigid collision when the hand-tearable steel contacts the guide roller 103. A telescopic rod 104 is fixed to the installation unit 102. A top plate 105 is fixed to the output end of the telescopic rod 104. A spring 106 is sleeved on the outer circumference of the telescopic rod 104, and both ends of the spring 106 are respectively connected to the installation unit 102. Unit 102 and top plate 105 are fixed together. There are multiple sets of telescopic rods 104 and top plates 105. The outer surfaces of multiple top plates 105 are all arc-shaped surfaces that are adapted to the inner ring of the hand-tearable steel coil. When installing the hand-tearable steel coil, the inner ring of the hand-tearable steel coil is fitted onto the outside of multiple top plates 105. During the fixing process, the top plate 105 set on the outer periphery of the installation unit 102 first contacts the inner ring of the hand-tearable steel coil. As the pressure of the inner ring of the hand-tearable steel coil on the top plate 105 gradually increases, the top plate 105 will compress the spring 106 on the outer periphery of the telescopic rod 104, causing the spring 106 to undergo elastic deformation. The rebound force of the spring 106 is used to adaptively adjust the support force of the top plate 105 on the inner ring of the hand-tearable steel coil. This not only avoids the strip from running off track due to the swaying of the steel coil during the uncoiling process, but also avoids the deformation of the inner ring of the hand-tearable steel coil due to excessive clamping.

[0030] In use, the device is first placed in a suitable position and connected to an external power supply and control wiring. The control equipment specifically includes known conventional equipment such as a controller or computer with control functions. Then, the operator places the hand-torn steel coil onto the mounting unit 102 of the uncoiler 1, and the mounting unit 102 supports and fixes the inner ring of the hand-torn steel coil. During the fixing process, the top plate 105 set on the outer periphery of the mounting unit 102 first contacts the inner ring of the hand-torn steel coil. As the pressure of the inner ring of the hand-torn steel coil on the top plate 105 gradually increases, the top plate 105 will compress the spring 106 on the outer periphery of the telescopic rod 104, causing the spring 106 to undergo elastic deformation. The rebound force of the spring 106 is used to adaptively adjust the support force of the top plate 105 on the inner ring of the hand-torn steel coil, so as to avoid the strip from deviating due to the swaying of the steel coil during the uncoiling process. After the installation of the hand-tearable steel coil is completed, the staff controls the drive unit 101 through the control equipment. The drive unit 101 drives the installation unit 102 and the hand-tearable steel coil to rotate synchronously, thereby unwinding the hand-tearable steel coil.

[0031] After being uncoiled, the hand-tearable steel strip is first guided by the guide roller 103. The flexible buffer layer on the outer periphery of the guide roller 103 can protect the extremely thin hand-tearable steel strip during the contact process, avoiding hard contact that could cause scratches or indentations on the strip surface. Subsequently, the strip enters the flattening assembly 4 located between the uncoiler 1 and the straightening assembly 3. Simultaneously, an external air source device delivers compressed air into the guide plate 405 through the air inlet pipe 409. The guide plate 405 is connected to the interior of the second flattening plate 402 through the connecting hole 203, allowing the compressed air to be ejected obliquely at a certain angle through the inclined exhaust hole 407. It is also connected to the interior of the first flattening plate 401 through the connecting pipe 408, allowing the compressed air to be ejected vertically upward through the vertical exhaust hole 406. When the hand-torn steel strip passes between the first flattening plate 401 and the second flattening plate 402, the airflow ejected from the vertical exhaust hole 406 forms a uniform supporting force on the lower surface of the strip, preventing the strip from sag due to its own weight and causing wrinkles. At the same time, the airflow ejected from the inclined exhaust hole 407 applies an outward tension along the width direction to the strip, which can quickly flatten the small wavy wrinkles or curls that may occur during the conveying process.

[0032] After being flattened, the hand-torn steel strip then enters the correction assembly 3. The drive roller 304 of the correction assembly 3 rotates under the drive of the rotary motor 311 through the drive wheel 312, the synchronous belt and the driven wheel, providing power for the conveying of the strip. When the strip deviates laterally during the conveying process and touches the roller 302 on the mounting frame 2, the roller 302 will drive the displacement amplifier 303 to move. The displacement amplifier 303 can amplify the small displacement when the hand-torn steel strip touches the roller 302, thereby driving the connecting plate 313 and the moving rod 307, which is movably set on the side of the connecting plate 313 through the slider 310 and the slide groove, to move synchronously, thereby causing the moving rod 307 to slide on the support rod 306. Since the outer peripheral surface of the moving rod 307 is hinged with the first connecting rod 308, when the moving rod 307 moves, it can drive the correction block 309 to extend radially on the surface of the drive roller 304 through the first connecting rod 308. Specifically, when the strip deviates to the left and touches the left roller 302, the left displacement amplifier 303 pulls the left moving rod 307 away from the center of the drive roller 304 through the connecting plate 313. At this time, the left correction block 309 extends outward from the surface of the drive roller 304 under the pull of the first connecting rod 308. Since the correction block 309 is tilted towards the center line of the mounting frame 2, the extended correction block 309 will apply a push to the right (i.e., the center line direction) to the edge of the deviated strip, thereby correcting the deviation of the strip.

[0033] In addition, a pull rod 404 is fixed to the side of the connecting plate 313. The other end of the pull rod 404 is hinged to the second connecting rod 403 on the lower surface of the second flat plate 402 in the flattening assembly 4. When the connecting plate 313 moves, it can drive the second flat plate 402 to rotate around its rotation axis through the pull rod 404 and the second connecting rod 403, thereby adjusting the angle of the oblique exhaust hole 407 opened on the surface of the second flat plate 402, and thus assisting the correction assembly 3 in correction. Specifically, when the strip shifts to the left, the left connecting plate 313 moves to the left, pulling the second connecting rod 403 via the pull rod 404, causing the second spreading plate 402 on the left to rotate. At this time, the angle of the left inclined exhaust hole 407 decreases, and the outward tension of the ejected airflow on the left edge of the strip weakens. Meanwhile, the right second spreading plate 402 maintains its initial angle, and the airflow ejected from the right inclined exhaust hole 407 still exerts a strong outward tension on the right edge of the strip. Under the action of the tension difference between the two sides, the strip will move to the right (centerline direction), further improving the correction effect and response speed.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall fall within the protection scope of the present invention.
