Description

Technical Field

[0001] This invention relates to the field of battery electrode production technology, specifically to a batch segmented cutting device for battery electrode roll production. Background Technology

[0002] With the rapid development of new energy vehicles, energy storage equipment and other fields, the demand for lithium batteries continues to surge, which puts forward stringent requirements on the efficiency, precision and safety of electrode production. As the core functional component of lithium batteries, the batch segmented cutting of electrode rolls is a key link connecting coating, rolling and winding and stacking processes, which directly determines the energy density, cycle life and safety performance of the cell. At present, the industry mainstream adopts wide electrode master rolls (width can reach 1-1.8 meters) to form narrow sub-rolls or fixed-length electrode sheets after segmented cutting, so as to adapt to the assembly needs of cells of different specifications. The efficiency and consistency of batch cutting have become the core demands for improving production capacity and controlling costs.

[0003] In the existing batch segmented cutting equipment for battery electrode roll production, the battery electrodes are prone to wrinkles due to uneven tension and conveying deviation during the batch cutting process, resulting in uneven cutting edges and dimensional accuracy deviations, which seriously affect the subsequent electrode assembly quality. The electrode clamping and fixing effect during cutting is not good, and the electrode slippage can easily lead to cutting deviations. In addition, the reciprocating motion stability of the cutting mechanism of some devices is insufficient, which cannot meet the needs of continuous batch cutting.

[0004] Based on this, the present invention designs a batch segmented cutting device for battery electrode roll production to solve the above problems. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention, by setting up a dual-shaft motor, a reciprocating turntable, a guide groove, a lifting spring, a smoothing roller, and a guide rod, allows the battery electrode sheets to be laid on the top of the cutting table and moved to the bottom of the cutting blade. The dual-shaft motor is then activated, driving the drive gear and the reciprocating turntable to rotate. This causes the reciprocating turntable to pull the reciprocating connecting frame up and down on both sides of the cutting table, moving the mounting frame down closer to the cutting table. The downward movement of the mounting plate compresses and deforms the lifting spring. Under the rotation of the reciprocating turntable and the rebound of the lifting spring, the mounting frame moves up and down on the top of the cutting table, causing the smoothing roller to press against the cutting table. At the top, the smoothing roller rolls along the inclined surface of the cutting table to smooth the battery electrode sheets. The guide rod slides inside the guide groove, allowing it to slide from the bottom of the vertical slide groove on one side of the guide groove along the inclined slide groove to the horizontal slide groove, where it engages with the concave frame two. This allows the smoothing roller to move upwards away from the cutting table after smoothing the battery electrode sheets and cutting them with the cutting blade, making it easier for the cut battery electrode sheets to fall onto the top of the conveyor belt. The drive gear drives the driven gear to rotate, and with the connection of the connecting strip, the conveyor belt rotates, conveying the battery electrode sheets that have fallen onto the top of the conveyor belt to the subsequent processing steps.

[0019] 2. This invention, by setting up guide rollers, push rollers, electric telescopic rods, a movable frame, movable protrusions, movable side plates, and a roll material, lifts the roll material and suspends it between two clamping turntables. The four electric telescopic rods are controlled to extend and retract synchronously, pushing the movable frame to slide up and down against the movable side plates. This allows the movable protrusions to slide within the adjusting groove, adjusting the distance between the two movable side plates so that the clamping turntables are close to both ends of the roll material. This causes the positioning blocks to engage with the corresponding positioning holes, facilitating the installation and fixing of roll material of different specifications. The battery electrode is then pulled out from the surface of the roll material and inserted between the two closely fitted push rollers until it passes through the push rollers and guide rollers and rests on the top of the cutting table. The push motor is started, and the meshing of the two push gears causes the two push rollers to rotate in opposite directions. Under friction, the battery electrode is pushed around the guide rollers and slides to the bottom of the cutting blade for cutting. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1-10 The present invention provides a technical solution:

[0035] A batch segmented cutting device for battery electrode roll production includes a base plate 1, a conveying mechanism 2 fixedly connected to one side of the top of the base plate 1, a driving mechanism 3 located near the conveying mechanism 2 on the base plate 1, a cutting table 4 fixedly installed on the base plate 1 at the top of the driving mechanism 3, with the edge of the cutting table 4 resting on one side of the top of the conveying mechanism 2, a cutting mechanism 5 located at the center of the top of the cutting table 4, a pushing and smoothing mechanism 6 located near the conveying mechanism 2 on the side of the cutting mechanism 5, a pushing mechanism 7 fixedly connected to the top of the base plate 1 on the side of the cutting table 4 away from the conveying mechanism 2, a clamping and mounting mechanism 8 located on the top of the base plate 1 away from the conveying mechanism 2, and a roll 9 located on the top of the clamping and mounting mechanism 8.

[0036] During operation, the roll 9 is fixed on the top of the clamping and mounting mechanism 8. The battery electrode sheet on the surface of the roll 9 is pulled out, passed through the pushing mechanism 7, and placed on the top of the cutting table 4. The pushing mechanism 7 is started to push the battery electrode sheet to slide on the top of the cutting table 4. The rotation speed of the drive mechanism 3 is controlled according to the cutting needs, which drives the cutting mechanism 5 to move up and down on the top of the cutting table 4 to press and cut the battery electrode sheet. When the cutting mechanism 5 moves down close to the top of the cutting table 4, the smoothing mechanism 6 is pushed to first press against the battery electrode sheet, smooth the battery electrode sheet, and then cut it. The cut battery electrode sheet falls on the conveying mechanism 2 and is conveyed to the subsequent processing steps.

[0037] As a further embodiment of the present invention, the conveying mechanism 2 includes a mounting side plate 201, and there are two mounting side plates 201. The two ends between the two mounting side plates 201 are rotatably mounted with a conveying roller 202 through a bearing. The surfaces of the two conveying rollers 202 are fitted with a conveyor belt 203. The two ends of one of the conveying rollers 202 pass through the mounting side plate 201 and are respectively fixedly connected to a linkage turntable 204.

[0038] During operation, the cut battery electrode sheets fall onto the top of the conveyor belt 203. Under the linkage of the linkage turntable 204, the conveyor roller 202 rotates, causing the conveyor belt 203 to rotate on the surface of the two conveyor rollers 202, thus conveying the battery electrode sheets that have fallen onto the top of the conveyor belt 203.

[0039] As a further embodiment of the present invention, the drive mechanism 3 includes a dual-output shaft motor 301. The output ends of the dual-output shaft motor 301 are respectively fixedly connected to rotating shafts 302. The two ends of the rotating shafts 302 are rotatably connected to support plates through bearings, and the bottom of the support plates is fixedly connected to the base plate 1. A drive gear 303 is fixedly installed at the center position between the two support plates of the rotating shaft 302. A driven gear 305 meshes with one side surface of the drive gear 303. The two ends of the driven gear 305 are rotatably connected to the support plates through bearings, and the bottom of the support plates is fixedly connected to the base plate 1. One end of the driven gear 305 passes through the support plate and is fixedly connected to a second linkage turntable 306. A connecting strip 307 is rotatably connected to one side edge of the second linkage turntable 306 through a protrusion. The end of the connecting strip 307 away from the second linkage turntable 306 is rotatably connected to the edge of the first linkage turntable 204 through a protrusion. The end of the rotating shaft 302 away from the dual-output shaft motor 301 passes through the support plate and is fixedly connected to a reciprocating turntable 304.

[0040] During operation, the dual-axis motor 301 is started, which drives the drive gear 303 and the reciprocating turntable 304 to rotate via the rotating shaft 302. The reciprocating turntable 304 rotates at the bottom of the reciprocating connecting frame 506, causing the protrusions on the edge of the reciprocating turntable 304 to pull the reciprocating connecting frame 506 to move up and down, which in turn drives the mounting frame 501 to move up and down to continuously cut the battery electrode sheets. At the same time, the drive gear 303 meshes with the driven gear 305, driving the second linkage turntable 306 to rotate. Under the connection of the connecting strip 307, the first linkage turntable 204 is driven to rotate, so that the conveyor belt 203 rolls synchronously to convey the cut battery electrode sheets that fall on the top of the conveyor belt 203.

[0041] As a further embodiment of the present invention, the cutting mechanism 5 includes a mounting frame 501, mounting plates 502 are fixedly connected to the bottom of both sides of the mounting frame 501, a connecting rod 503 is fixedly connected to the bottom of each mounting plate 502, a fixed frame 504 is slidably connected to the bottom of the three connecting rods 503, a lifting spring 505 is sleeved on the surface of the connecting rods 503 between the mounting plate 502 and the fixed frame 504, and a reciprocating connecting frame 506 is fixedly connected to the bottom of the three connecting rods 503 through the fixed frame 504, and the bottom of the reciprocating connecting frame 506 is slidably connected to the protrusion at the edge of the reciprocating turntable 304;

[0042] During operation, the reciprocating turntable 304 rotates, pulling the reciprocating connecting frame 506 to slide up and down at the bottom of the fixed frame 504, causing the connecting rod 503 to slide up and down at the top of the fixed frame 504. This compresses the lifting spring 505, causing it to deform and rebound on the surface of the connecting rod 503. Under the pushing action of the reciprocating turntable 304 and the rebound action of the lifting spring 505, the mounting frame 501 is pushed to move up on the top of the cutting table 4, driving the mounting frame 501 to move up and down on the top of the cutting table 4 to continuously cut the battery electrode sheets.

[0043] As a further embodiment of the present invention, a rectangular slide groove 507 is provided through one side of the mounting bracket 501. Mounting slide rods 508 are fixedly installed on both sides of the inner wall of the rectangular slide groove 507. A concave frame 509 is slidably connected through the surfaces of the two mounting slide rods 508. The concave frame 509 slides close to the inner wall of the rectangular slide groove 507. A pressure roller 510 is rotatably installed at the bottom of the concave frame 509 via a rotating shaft. A pressure spring 511 is sleeved on the top surfaces of the mounting slide rods 508 at both ends of the concave frame 509. A cutting blade 512 is fixedly connected to the bottom of the mounting bracket 501 on the side of the opening of the rectangular slide groove 507.

[0044] During operation, when the mounting bracket 501 is pressed down close to the cutting table 4, the clamping roller 510 contacts the cutting table 4 before the cutting blade 512. When the cutting blade 512 cuts the battery electrode, the clamping roller 510 presses against the surface of the battery electrode, lifting the concave bracket 509 to slide and compress the clamping spring 511 on the surface of the mounting slide rod 508, causing it to deform. Under the rebound action of the clamping spring 511, the clamping roller 510 is pressed down, so that the clamping spring 511 clamps and fixes the battery electrode, ensuring that the cutting blade 512 will not slip when cutting the battery electrode.

[0045] As a further embodiment of the present invention, the smoothing mechanism 6 includes a fixed rod 601, and the two ends of the fixed rod 601 are fixedly connected to the two sides of the mounting frame 501. Multiple arc-shaped mounting rods 602 are fixedly installed at equal intervals on the surface of the fixed rod 601, and the end of the arc-shaped mounting rod 602 away from the fixed rod 601 is fixedly connected to the mounting frame 501. A rotating pressure plate 603 is slidably connected through the surface of the arc-shaped mounting rod 602, and an arc-shaped spring 604 is sleeved on the surface of the arc-shaped mounting rod 602 on the side of the rotating pressure plate 603 away from the fixed rod 601. A rotating column 605 is fixedly connected to the bottom of the multiple rotating pressure plates 603, and the two ends of the rotating column 605 are rotatably connected to the two sides of the mounting frame 501 through bearings. A concave frame 606 is fixedly connected to the bottom of the surface of the rotating column 605, and a smoothing roller 607 is rotatably installed on the bottom of the concave frame 606 through a rotating shaft.

[0046] During operation, when the mounting bracket 501 moves down close to the cutting table 4, the smoothing roller 607 moves down close to the cutting table 4 and covers the surface of the battery electrode. The cutting table 4 then pushes and lifts the smoothing roller 607 to rotate around the rotating column 605, causing the rotating pressure plate 603 to slide on the surface of the arc-shaped mounting rod 602, compressing the arc-shaped spring 604 and deforming it. Under the rebound action of the arc-shaped spring 604, the rotating pressure plate 603 is lifted up, pressing the smoothing roller 607 tightly onto the surface of the battery electrode. This allows the smoothing roller 607 to push the battery electrode to smooth it, ensuring that no wrinkles occur when cutting the battery electrode.

[0047] As a further embodiment of the present invention, mounting sleeves 608 are fixedly connected to both ends of the top of the concave frame 606. A guide rod 609 is slidably connected through the inside of the mounting sleeve 608. A limiting push plate 610 is fixedly connected to the surface of the guide rod 609 located inside the mounting sleeve 608, and a limiting end plate 611 is fixedly connected to the end of the guide rod 609 away from the limiting push plate 610 through the mounting sleeve 608. A return spring 612 is sleeved on the surface of the guide rod 609 located on the side of the limiting push plate 610, and the return spring 612 is located inside the mounting sleeve 608; the top of the cutting table 4 is inclined, close to One side of the conveying mechanism 2 is higher, and a cut 401 is provided through the center of the top of the cutting table 4. The cut 401 corresponds to the position of the cutting blade 512. The fixing frame 504 is fixedly connected to the center of both sides of the cutting table 4. A guide roller 402 is rotatably installed on the side of the cutting table 4 away from the conveying mechanism 2 through a bearing. Guide plates 403 are symmetrically fixed at both ends of the top of the cutting table 4 on the side of the cut 401 away from the guide roller 402. The two guide plates 403 are respectively provided with guide grooves 404 on opposite sides. The end of the guide rod 609 away from the limiting end plate 611 is slidably engaged in the guide groove 404.

[0048] During operation, the return spring 612 pushes up the limiting push plate 610, causing the guide rod 609 to be locked inside the guide groove 404. When the concave frame 606 rotates, it drives the guide rod 609 to slide inside the guide groove 404. The guide rod 609 slides from the bottom of the vertical slide groove of the guide groove 404 along the inclined slide groove, causing the guide rod 609 to slide on the inclined surface of the inclined slide groove of the guide groove 404 and push up the guide rod 609. This causes the return spring 612 to deform inside the mounting sleeve 608 until one end of the guide rod 609 slides from the inclined slide groove of the arc spring 604 to the horizontal slide groove. Under the return spring 612, the guide rod 609 is pushed up, causing the guide rod 609 to be lifted out of the inclined slide groove of the guide groove 404 and locked inside the horizontal slide groove, thus limiting the guide rod 609.

[0049] As a further embodiment of the present invention, the pushing mechanism 7 includes a fixed side plate 701, and there are two fixed side plates 701. The two fixed side plates 701 are fixedly fixed on both sides of the top of the base plate 1. A pushing motor 702 is fixedly connected to the bottom of one side of one of the fixed side plates 701. A pushing rubber roller 703 is symmetrically mounted between the two fixed side plates 701 through a bearing. The surfaces of the two pushing rubber rollers 703 are in close contact with each other. The two ends of the pushing rubber roller 703 pass through the fixed side plate 701 and are respectively fixedly connected to a pushing gear 704. The two pushing gears 704 on the same side mesh with each other. The output end of the pushing motor 702 is fixedly connected to one of the pushing gears 704.

[0050] During operation, after the battery electrode sheet is pulled out from the surface of the roll 9 and inserted between the two push rollers 703, the push motor 702 is started to drive the push gear 704 to rotate. Through the meshing of the two push gears 704, the two push rollers 703 are controlled to rotate relative to each other, so that the push rollers 703 rotate on the surface of the battery electrode sheet. Under the action of friction, the battery electrode sheet is pushed to the top of the cutting table 4 for cutting.

[0051] As a further embodiment of the present invention, a movable slide groove 101 is provided through one side of the top of the base plate 1, and limiting slide grooves 102 are symmetrically provided on both sides of the inner wall of the movable slide groove 101.

The bottoms of the two movable side plates 801 are slidably connected to the inside of the movable slide groove 101, and movable rollers 802 are rotatably mounted on both sides of the bottom of the two movable side plates 801 through a rotating shaft. The movable rollers 802 are tumbledly connected to the inside of the limiting slide grooves 102. Movable protrusions 803 are fixedly connected to the bottom of both sides of the movable side plates 801, and electric telescopic mechanisms are fixedly connected to the top of both sides of the movable side plates 801. The telescopic ends of the electric telescopic rod 804 on the same side of the two movable side plates 801 are fixedly connected to the movable frame 805. The convex plates on the opposite side of the two movable frames 805 slide against the inner wall of the movable slide groove 101. The movable frame 805 is symmetrically provided with adjusting slide grooves 806 on both sides, and the adjusting slide grooves 806 are slidably connected to the surface of the movable protrusion 803. The top of the opposite side of the two movable side plates 801 is rotatably mounted with a clamping turntable 807 through a bearing. Multiple positioning blocks 808 are fixedly installed on the opposite side of the two clamping turntables 807. Multiple positioning holes 901 are provided at both ends of the roll 9, and the positions of the positioning holes 901 and the positioning blocks 808 correspond to those of the positioning blocks 808.

[0052] During operation, after lifting the roll 9 and moving it between the two movable side plates 801, aligning the positioning insertion hole 901 with the positioning block 808, control the extension and retraction of the electric telescopic rod 804, causing the movable frame 805 to slide close to both sides of the movable side plate 801, allowing the movable protrusion 803 to slide inside the adjusting slide groove 806, controlling the distance between the two movable side plates 801, and causing the movable roller 802 to roll inside the corresponding limiting slide groove 102, limiting the movement of the movable side plate 801 until the clamping turntable 807 approaches both ends of the roll 9, causing the positioning block 808 to insert into the corresponding positioning insertion hole 901, clamping the roll 9 between the two clamping turntables 807.

[0053] Working principle of this invention:

[0054] The operator lifts the roll 9 and suspends it between the clamping turntables 807 on the top of the two movable side plates 801, ensuring that the positioning holes 901 at both ends of the roll 9 are roughly aligned with the positioning blocks 808 on the clamping turntables 807. The operator then activates the four electric telescopic rods 804 to control their synchronous extension and retraction, pushing the movable frames 805 on both sides to slide up and down along the surface of the movable side plates 801. At this time, the adjusting slide 806 on the movable frame 805 slides relative to the movable protrusion 803 at the bottom of the movable side plate 801, adjusting the distance between the two movable side plates 801. The movable roller 802 at the bottom of the movable side plate 801 rolls in the limiting slide 102 of the base plate 1, limiting the movement direction of the movable side plate 801 to avoid deviation. As the distance decreases, the clamping turntable 807 gradually presses against both ends of the roll 9, and the positioning block 808 accurately engages in the corresponding positioning hole 901, firmly clamping the roll 9 between the two clamping turntables 807, completing the installation and positioning of the roll.

[0055] After the roll material is fixed, the battery electrode sheet is pulled out from the surface of the roll 9 and its free end is inserted between two closely spaced push rollers 703. The battery electrode sheet is continuously pulled so that it passes through the push rollers 703 and the guide rollers 402 in sequence, and finally rests on the inclined top surface of the cutting table 4 until the front end of the battery electrode sheet moves above the cut 401 corresponding to the cutting blade 512. The push motor 702 is started, and its output end drives the push gear 704 to rotate. The two push rollers 703 rotate synchronously in opposite directions. The push rollers 703 generate friction with the surface of the battery electrode sheet. With the help of this friction, the battery electrode sheet is smoothly pushed forward. After the battery electrode sheet passes around the guide rollers 402, it slides along the inclined top surface of the cutting table 4 and continues to feed into the cutting area below the cutting blade 512, providing continuous battery electrode sheet raw materials for batch segmented cutting.

[0056] The dual-output shaft motor 301 is restarted, and its two output ends drive the two rotating shafts 302 to rotate synchronously. The two ends of the rotating shafts 302 are fixed to the base plate 1 by support plates to ensure rotational stability. The end of the rotating shaft 302 away from the dual-output shaft motor 301 drives the reciprocating turntable 304 to rotate. The protrusion at the edge of the reciprocating turntable 304 is slidably connected to the bottom end of the reciprocating connecting frame 506. The circumferential motion of the protrusion is converted into the up-and-down reciprocating motion of the reciprocating connecting frame 506, providing power to the cutting mechanism 5. When the mounting frame 501 moves down and approaches the cutting table 4 under the drive of the reciprocating connecting frame 506, it pushes the smoothing roller 607 to contact the surface of the battery electrode before the cutting blade 512. Since the top of the cutting table 4 is inclined, after the smoothing roller 607 contacts the battery electrode, under the pressure of the continuous downward movement of the mounting frame 501, it rotates around the rotating column 60 5. Rotation: At this time, the rotating pressure plate 603 at the top of the rotating column 605 slides along the arc-shaped mounting rod 602, compressing the arc-shaped spring 604 and deforming it. The rebound force of the arc-shaped spring 604 is transmitted to the smoothing roller 607 through the rotating pressure plate 603 and the rotating column 605, so that the smoothing roller 607 is in close contact with the surface of the battery electrode and rolls along the surface of the battery electrode as the mounting frame 501 moves down, smoothing the wrinkles on the battery electrode. At the same time, the pressing roller 510 also contacts the battery electrode. The reaction force of the cutting table 4 pushes the pressing roller 510 to drive the concave frame 509 to move up along the mounting slide rod 508, compressing the pressing spring 511. The rebound pressure of the pressing spring 511 makes the pressing roller 510 press tightly against the surface of the battery electrode, pressing and fixing the battery electrode on the cutting table 4 to prevent the battery electrode from sliding and shifting during cutting.

[0057] During this process, the guide rod 609 at the top of the concave frame 606 is engaged in the guide groove 404 on the opposite side of the two guide plates 403 under the rebound action of the return spring 612. As the smoothing roller 607 rotates, the guide rod 609 slides from the bottom of the vertical slide groove of the guide groove 404 along the inclined slide groove. During the sliding process, the guide rod 609 is pushed up, which drives the limiting push plate 610 to squeeze the return spring 612. When the guide rod 609 slides to the transverse slide groove of the guide groove 404, the return spring 612 rebounds and pushes the guide rod 609 into the transverse slide groove, limiting the concave frame 606 and ensuring that the smoothing roller 607 remains in a pressed state.

[0058] When the mounting bracket 501 moves down to its lowest point, the cutting blade 512 at its bottom passes through the cut 401 and cuts the battery electrode sheet that is pressed and fixed below, completing the cutting operation of one section of battery electrode sheet. After the cutting is completed, the rebound force of the lifting spring 505 pushes the mounting plate 502 upward, causing the mounting bracket 501 to move upward as a whole. At the same time, the reciprocating turntable 304 continues to rotate, pushing the reciprocating connecting bracket 506 upward, further causing the mounting bracket 501 to reset. At this time, the guide rod 609 disengages from the transverse sliding groove of the guide groove 404, and the smoothing roller 607 moves upward with the mounting bracket 501 away from the surface of the battery electrode sheet, leaving space for the next section of battery electrode sheet to be fed. The mounting bracket 501 reciprocates... Driven by the continuous drive of the disc 304 and the rebound action of the lifting spring 505, the disc moves up and down along the top of the cutting table 4. Combined with the continuous feeding of the pushing mechanism 7, the battery electrode sheets are cut in batches and segments. Under the guidance of their own gravity and the inclined top surface of the cutting table 4, the cut battery electrode sheets slide from the edge of the cutting table 4 to the top of the conveyor belt 203 of the conveying mechanism 2. The conveyor roller 202 rotates under the drive of the linkage turntable 204, which in turn drives the conveyor belt 203 to rotate cyclically on the surface of the two conveyor rollers 202. The cut battery electrode sheets that fall on the conveyor belt 203 are smoothly transported to the subsequent processing station as the conveyor belt 203 rotates, completing the entire batch segment cutting and conveying process.
