Description

Technical Field

[0001] This invention relates to the field of battery cell manufacturing equipment technology, and in particular to a slitting machine for the production of supercapacitor electrodes. Background Technology

[0002] In the manufacturing of supercapacitor cells, in order to improve production efficiency and material utilization, the early coating and rolling processes are usually carried out continuously on a wide current collector. However, the electrode sheets that are finally assembled into capacitor cores are often in the shape of long and narrow strips. Relying solely on manual cutting or multiple single stamping machines to operate separately is not only extremely inefficient, but also makes it difficult to ensure the consistency of the narrow strip dimensions. Especially when dealing with large-area electrode materials, discontinuous stamping methods can easily cause severe burrs and dimensional deviations at the edges of the electrode sheets, which can lead to many safety hazards during subsequent winding.

[0003] The electrode slitting machine adopts a continuous roll-to-roll process of unwinding, correction, slitting and rewinding. This allows it to continuously and evenly slit wide electrode sheets into multiple rolls of narrow electrode sheets, just like cutting noodles, under high tension and high speed, which greatly improves production efficiency and dimensional consistency.

[0004] After the current supercapacitor electrodes are slitting, the slitting electrodes need to be rolled up and collected. However, aluminum foil current collectors have low hardness and good ductility. If the cutting tool is not sharp enough or the angle is not matched during slitting, burrs will be formed at the cut edge. These burrs can easily puncture the supercapacitor separator during subsequent assembly, leading to short circuit failure and adversely affecting the production quality of the supercapacitor.

[0012] Optionally, an air pump is fixedly installed on the outer side of the transmission positioning plate, and an extension tube is fixedly installed at one end of the air pump that passes through the transmission positioning plate. The extension tube is rotatably installed on the outer side of the first gear rack. A separation suction mesh is fixedly installed on the outer side of the first gear rack.

[0013] Optionally, a slitting assembly is provided between the slitting conveying assembly and the slitting assembly.

[0017] Optionally, the number of the double-layer processing components is multiple sets, and an electrode winding area is provided between each two sets of the double-layer processing components.

[0018] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0019] 1. The grinding blocks in the collecting roller assembly of the positioning and winding assembly rotate with the double-layer processing assembly to rub and polish the burrs on the side of the electrode sheet. At the same time, the dust suction chamber adsorbs the detached burr residue, further reducing the burr risk and improving the winding quality of the supercapacitor electrode sheet.

[0020] 2. In the slitting and conveying assembly, the first and second toothed racks rotate relative to each other. The residual dust on the lower surface of the electrode sheet is sucked in and cleaned by the separation suction mesh and suction pump. At the same time, the auxiliary guide roller of the slitting assembly simultaneously adsorbs the powder generated during the cutting process to prevent dust from falling onto the electrode sheet.

[0021] 3. The slitting assembly is driven by a hydraulic telescopic frame to move the built-in rotary drum frame up and down. Combined with the arc trajectory of the inclined guide rail, the slitting cutter slides along the central guide rail to adjust the spacing, adapting to the cutting needs of electrode sheets of different widths.

[0022] 4. The continuous roll-to-roll process replaces manual cutting, and the continuous transfer of the electrode sheets is achieved through multiple sets of rotating rollers and guide rods of the slitting conveyor assembly. Combined with the high-speed slitting of the slitting assembly, the electrode sheet diversion processing is completed in an integrated manner.

[0023] 5. The collecting roller assembly adjusts the clamping range of the double-layer processing assembly through the folding motion of the diamond folding frame to adapt to winding electrode sheets of different diameters. At the same time, when the electric telescopic rod in the multi-layer hollow ring slides, it generates a slight negative pressure adsorption through the airflow in the corresponding area, so that the electrode sheet fits tightly against the collecting shell, reducing winding gaps and interlayer misalignment.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] like Figure 1 , Figure 2 , Figures 4-8As shown, the present invention proposes a slitting machine for producing supercapacitor electrodes, comprising a slitting machine support assembly 1, a positioning and winding assembly 4 installed on one side of the slitting machine support assembly 1 for collecting the slitting electrodes, a collection area plate 102 fixedly installed at the bottom of the winding plate 401, a slitting and cutting area plate 101 fixedly installed on one side of the collection area plate 102, a slitting and conveying assembly 2 installed on the top of the slitting machine support assembly 1, the slitting and conveying assembly 2 comprising two conveying and positioning plates 201 fixedly installed on the top of the slitting and cutting area plate 101, multiple rotating rollers 202 rotatably mounted between the two conveying and positioning plates 201, the multiple rotating rollers 202 forming a conveying track for the supercapacitor electrodes, a guide rod 206 rotatably mounted between the two conveying and positioning plates 201, and a double guide rod 206 fixedly mounted on the outer side of the guide rod 206. A second gear rack 205 is rotatably mounted inside the bidirectional hinge frame 207. The side of the bidirectional hinge frame 207 away from the guide rod 206 is bolted to the surface of the transmission positioning plate 201. A first gear rack 204 is meshed with the outer side of the second gear rack 205. The first gear rack 204 is rotatably mounted on the surface of the transmission positioning plate 201. An air suction pump 209 is fixedly mounted on the outer side of the transmission positioning plate 201. An extension tube 210 is fixedly mounted at one end of the air suction pump 209 that passes through the transmission positioning plate 201. The extension tube 210 is rotatably mounted on the outer side of the first gear rack 204. A separation suction mesh 211 is fixedly mounted on the outer side of the first gear rack 204. The separation suction mesh 211 and the first gear rack 204 are in a communicating state. An electrode conduction roller 208 is provided on the surface of the transmission positioning plate 201.

[0047] In this embodiment, during the processing of supercapacitor electrodes, the supercapacitor electrode material is first installed in a collecting roller. The supercapacitor electrode material in the collecting roller is then transferred to a rotating roller 202. Multiple auxiliary motors connected to the rotating roller 202 are fixedly installed on the transfer positioning plate 201. Driven by the multiple rotating rollers 202, they rotate, thereby guiding the supercapacitor electrode material towards the slitting assembly 3. It should be noted that the second gear rack 205 consists of a gear and a center rod. Depending on the actual thickness of the supercapacitor electrode material, the center rod in the second gear rack 205 can be replaced with one of different diameters. Replacement is achieved by removing the screw fixing the bidirectional hinge frame 207, detaching the bidirectional hinge frame 207 from the second gear rack 205 from the guide rod 206, and then replacing it. The supercapacitor electrode material passes through... The second gear rack 205 connects with the first gear rack 204 to the guide rod 206. The purpose of setting multiple sets of rotating rollers 202 and guide rods 206 is to provide more support during the transport of the supercapacitor electrode material, preventing surface loosening due to insufficient support. After slitting, the supercapacitor electrode material enters the processing area of ​​the positioning and winding assembly 4 along the electrode conveying roller 208. The remaining material strips on the side of the slitting material can move towards the remaining material receiving roller 203 at the positioning and winding assembly 4 along the conveying positioning plate 201 until they are collected by the remaining material collecting roller at the winding plate 401. This completes the integrated slitting processing of the supercapacitor electrode material, improving the production efficiency of the supercapacitor electrode material.

[0048] Furthermore, since the second gear rack 205 is meshed with the first gear rack 204, a guide motor connected to the first gear rack 204 is fixedly installed on the transmission positioning plate 201. The guide motor drives the first gear rack 204 to rotate in the opposite direction, causing the second gear rack 205 to rotate in the forward direction. The second gear rack 205 rubs against the upper surface of the supercapacitor electrode material, guiding the supercapacitor electrode material to move rapidly towards the slitting assembly 3. Meanwhile, the first gear rack 204 drives the separation suction mesh 211 to move in the opposite direction along the lower surface of the supercapacitor electrode material. The two generate relative friction, causing the supercapacitor electrode material to... The material is subjected to a counterforce, which increases the friction between the lower surface of the supercapacitor electrode material and the separation suction mesh 211. This scrapes off any residual dust or other debris that may be present on the lower surface of the supercapacitor electrode material. The suction pump 209 continuously generates suction through the extension tube 210. As the separation suction mesh 211 rotates along the extension tube 210, the suction transmitted by the extension tube 210 draws the scraped residual dust into the first gear 204 through the small holes on the surface of the separation suction mesh 211. This reduces the impact of residual dust from previous steps on subsequent slitting steps during the transportation stage and improves the stability of the supercapacitor electrode material before slitting.

[0049] like Figure 6 , Figures 9-10 As shown, a slitting assembly 3 is provided between the slitting conveyor assembly 2 and the slitting assembly 3. The slitting assembly 3 includes a hollow support 302 fixedly installed on one side of the conveyor positioning plate 201. A slider-type motor frame 303 is slidably installed inside the hollow support 302. A hydraulic telescopic frame 301 is fixedly installed on the top of the hollow support 302. The slider-type motor frame 303 is fixedly installed at the output end of the hydraulic telescopic frame 301. An internal rotary drum frame 304 is fixedly installed at the output end of the slider-type motor frame 303. An auxiliary guide roller 305 is provided on the outside of the internal rotary drum frame 304. The two conveyor positioning plates 201 rotate between each other. The auxiliary guide roller 305 is equipped with a slitting support cleaning frame 306 and a central guide rail 309 in the middle. The auxiliary guide roller 305 is symmetrically arranged with multiple sets of inclined guide rails 310 around the center line of the central guide rail 309. A double slide rod positioning frame 307 is fixedly installed on the side of the slider motor frame 303 facing the roller 202. Multiple sets of sliding cutters 308 are slidably installed on the outside of the double slide rod positioning frame 307. The multiple sets of sliding cutters 308 are slidably installed inside the central guide rail 309 and the multiple sets of inclined guide rails 310. A diverting roller 406 for collecting supercapacitor electrode residue is provided at the bottom of the take-up plate 401.

[0050] In this embodiment, when the supercapacitor electrode material enters the processing area of ​​the slitting assembly 3, the hydraulic telescopic frame 301 drives the slider motor frame 303 to move downward along the hollow support 302 until the slider motor frame 303 drives the built-in rotary drum frame 304 and the auxiliary guide roller 305 to contact the supercapacitor electrode material, until the slitting cutter 308 on the auxiliary guide roller 305 contacts the supercapacitor electrode material, thereby achieving slitting, thus enabling the slitting of supercapacitor electrode materials of different thicknesses.

[0051] Furthermore, the drive inside the slider motor frame 303 drives the built-in rotating drum frame 304 and the auxiliary guide roller 305 to rotate. Since the slider motor frame 303 is confined inside the hollow support 302, it can only slide up and down along the hollow support 302. Therefore, the double sliding rod positioning frame 307 connected to the slider motor frame 303 also cannot rotate. When the auxiliary guide roller 305 rotates, the central guide rail 309, located in the middle, maintains its trajectory, and the central guide rail 309 connected to the central guide rail 309... The slitting cutter 308 slits the middle of the supercapacitor electrode material. Since the trajectory of the inclined guide rail 310 is inclined, each slitting cutter 308 connected to the inclined guide rail 310 slides along the arc trajectory of the inclined guide rail 310 on the double slide rod positioning frame 307 until the spacing between each slitting cutter 308 becomes larger or smaller, thereby changing the spacing between the slitting cutter 308 cutting the supercapacitor electrode material, thus adapting to supercapacitor electrode materials with different cutting requirements and reducing processing costs.

[0052] Furthermore, the slitting support cleaning frame 306 includes a mechanism consistent with the separation suction mesh 211, the extension tube 210, and the suction pump 209. That is, the slitting support cleaning frame 306 not only guides the supercapacitor electrode material but also cleans it. Currently, when the supercapacitor electrode material is slitted, the hard active carbon coating of the supercapacitor electrode material will also produce powder when it is cut. If these micron-sized dusts fall onto the electrode, they will move with the electrolyte inside the capacitor, gradually consuming the electrolyte and adhering to the separator, which will significantly shorten the cycle life of the supercapacitor. Therefore, the cut supercapacitor electrode material will slide along the slitting support cleaning frame 306 for transmission. The powder falling off the cut part of the supercapacitor electrode material will be absorbed by the slitting support cleaning frame 306, thereby improving the safety of the supercapacitor electrode during the slitting stage and extending the service life of the supercapacitor electrode.

[0053] like Figures 1-15As shown, the positioning and winding assembly 4 includes two winding plates 401 fixedly installed on the top of the collection area plate 102. An auxiliary motor 402 is fixedly installed on the outer side of the winding plate 401. A gear 403 is fixedly installed on the output end of the auxiliary motor 402. An auxiliary gear 404 is meshed on the outer side of the gear 403. A core roller 405 is fixedly installed inside the auxiliary gear 404. The core roller 405 is rotatably installed inside the winding plate 401. A set of residual material receiving rollers 203 is provided on the surface of both the winding plate 401 and the transmission positioning plate 201. The collection roller assembly 5 is fixedly installed on the core roller 401. The outer collecting shell 501 is rotatably mounted on the outer side of the auxiliary rotating roller 407, away from the core rotating roller 405. A transverse sliding groove 502 and a communicating vertical sliding groove 504 are formed on the surface of the collecting shell 501. A double-layer processing assembly 503 is slidably mounted inside the transverse sliding groove 502 and the vertical sliding groove 504. An extension positioning frame 508 is fixedly mounted at one end of the double-layer processing assembly 503 extending into the collecting shell 501. A cavity positioning frame 506 is slidably mounted on the outer side of the extension positioning frame 508. The cavity positioning frame 506 is fixedly mounted on the auxiliary rotating roller 407. A grinding block 512 is provided on the outer side of the roller 407 and the outer side of the double-layer processing assembly 503. When the slit supercapacitor electrode sheets arrive at the positioning and winding assembly 4, the auxiliary motor 402 drives the gear 403 to rotate. The gear 403 meshes with the auxiliary gear 404, which in turn drives the auxiliary gear 404 to rotate. The auxiliary gear 404 drives the collecting shell 501 to rotate via the core rotating roller 405, winding up the slit supercapacitor electrode sheets. During this process, the auxiliary rotating roller 407 drives the extension positioning frame 508 to rotate along the inside of the collecting shell 501 via the sliding cavity positioning frame 506. The positioning frame 508 extends to one end outside the collection shell 501 and is fixed to the double-layer processing component 503. The double-layer processing component 503 can slide along the vertical sliding groove 504, that is, the double-layer processing component 503 can rotate along the trajectory of the vertical sliding groove 504. When the grinding block 512 rotates with the double-layer processing component 503, it can rub and grind the burrs that may appear on the side of the supercapacitor electrode after slitting. Thus, in the process of clamping and separating the supercapacitor electrode, the burrs on the side of the supercapacitor electrode are also removed, thereby improving the production quality of the supercapacitor.

[0054] In this embodiment, an auxiliary folding block 511 is provided on one side of the extended positioning frame 508, and a rhomboid folding frame 507 is hinged to both sides of the auxiliary folding block 511. An electric telescopic rod 509 is fixedly installed in the middle of the sliding cavity positioning frame 506, and the telescopic end of the electric telescopic rod 509 is fixedly installed at the upper and lower hinge ends of the rhomboid folding frame 507. A dust suction chamber 513 is fixedly installed inside the double-layer processing assembly 503. It is noted that the vertical sliding groove 504 and the horizontal sliding groove 502 are connected, and the vertical sliding groove 504 and the horizontal sliding groove 502 form a T-shaped track, so that the double-layer processing assembly 503 can slide horizontally along the horizontal sliding groove 502 and vertically along the vertical sliding groove 504. When clamping supercapacitor electrodes of different diameters, the electric telescopic rod 509 performs telescopic movement. Since the rhomboid folding frame 507 includes a first folding frame and a first insert rod at the folding connection, and the electric telescopic rod 509 is fixed to the insert rod, when the telescopic end of the electric telescopic rod 509 moves up and down, it causes the rhomboid folding frame 507 to fold. The auxiliary folding block 511, which is hinged to the inside of the rhomboid folding frame 507, also folds. The auxiliary folding block 511 includes a second folding frame and a second insert rod. The second insert rod is fixedly installed in the center of the extension positioning frame 508. During the folding process, the auxiliary folding block 511 drives the extension positioning frame 508 to slide along the transverse sliding groove 502 to adjust the gap in the collection shell 501, which is the clamping range of the supercapacitor electrode, so that the supercapacitor electrode can be stably limited, thereby improving the winding and positioning accuracy of the supercapacitor electrode.

[0055] Furthermore, when the double-layer processing component 503 rotates back and forth, the dust suction chamber 513 enters the area between the grinding blocks 512 to rub and deburr the sides of the supercapacitor electrode, and can adsorb the detached burrs. At the same time, when the supercapacitor electrode is finished being wound up, the diamond-shaped folding frame 507 folds inward. At this time, the double-layer processing component 503 can slide along the transverse sliding groove 502, that is, the gap between the double-layer processing component 503 and the electrode winding area 505 becomes larger, so the workers can completely clean the remaining burr residue, thereby further reducing the impact of burrs and other objects on the subsequent manufacturing of the supercapacitor electrode.

[0056] like Figures 13-16As shown, there are multiple sets of double-layer processing components 503. Between each pair of double-layer processing components 503, there is an electrode winding area 505. A multi-layered hollow ring 510 is rotatably mounted on the inner wall of the collecting shell 501 at the electrode winding area 505. An electric telescopic rod 509 is slidably installed inside the multi-layered hollow ring 510. Multiple airflow corresponding areas 514 are opened on the outer side of the multi-layered hollow ring 510. It should be noted that the multi-layered hollow ring 510 has two relatively enclosed spaces, and the electric telescopic rod 509 extends to one side of the enclosed space as an arc-shaped sealing block. The arc-shaped sealing block can slide up and down against the sealed space, allowing the electric telescopic rod 509 to pass through the airflow corresponding areas when sliding in the sealed space. 514 serves as a process for converting airflow to the outside environment. When the supercapacitor electrode is being wound up, the gap between the double-layer processing components 503 is usually at its maximum. At this time, the end of the electric telescopic rod 509 extending into the enclosed space is in close contact with the airflow corresponding area 514. As the gap between the double-layer processing components 503 changes, the electric telescopic rod 509 moves along the enclosed space in a piston-like motion. The airflow corresponding area 514 generates a slight negative pressure adsorption on the supercapacitor electrode through the small holes on the surface of the electrode winding area 505. This allows the supercapacitor electrode to fit well with the collection shell 501 at the beginning of winding, reducing gaps generated during the winding of the supercapacitor electrode and improving the winding quality.

[0057] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
