Description

Technical Field

[0001] This invention relates to the field of lithium battery technology, and in particular to an automatic lithium battery cutting and stacking machine. Background Technology

[0002] Lithium-ion batteries have low individual cell voltages and need to be stacked in series and parallel configurations. This necessitates an efficient, accurate, and stable stacking method, leading to the development of integrated lithium-ion battery cutting and stacking machines. Lithium-ion batteries typically employ a multi-layered stacked structure, requiring cutting and stacking according to predetermined dimensions and quantities. However, current technologies necessitate multiple cuts of the separator, and the adhesive curing time for bonding multiple electrode sheets is lengthy, consuming significant time. Furthermore, during electrode stacking, impurities easily adhere to the surface of the electrode sheets, forming a barrier that hinders internal battery reactions. During battery cycling, this leads to a decrease in battery capacity, shortening battery life and potentially affecting product quality. After prolonged use, due to lifespan limitations, powder shedding from the electrode sheets can occur, potentially causing internal short circuits and thermal runaway. Additionally, uneven adhesive application during electrode sheet coating can cause adhesive to compress the electrode sheets after drying, resulting in a deteriorated battery interface and uneven current distribution. Therefore, we propose an automatic lithium-ion battery cutting and stacking machine. Summary of the Invention

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0015] 1. This invention proposes an automatic lithium battery cutting and stacking machine. It employs an integrated mechanism where a lifting sliding seat moves to drive a cutting machine to cut electrode sheets. A lifting frame moves the sliding frame downwards, causing multiple suction cups to contact the electrode sheets. At this point, an air pump draws airflow, creating negative pressure around the suction cups and adsorbing the electrode sheets. The electrode sheets are then moved to the opening at the top of the heating chamber via an electric conveyor rail and moved downwards by a cylinder. They can then be placed on a second conveyor belt. By continuously laying separators on the surface of multiple electrode sheets, the separators only need to be cut during the final layering. This allows for rapid stacking of multiple electrode sheets, improving stacking efficiency and avoiding the need for multiple cuts of the separator during stacking, thus increasing work efficiency.

[0016] 2. This invention proposes an automatic lithium battery stacking machine. When transporting electrode sheets to the inlet of the heating box, an air pump blows airflow into the air inlet pipe and into the interior of two protective boxes. The airflow pushes the corrector block to move towards the sliding frame. The fixing block on the surface of the corrector block contacts the sliding frame, which can push the sliding frame to move. At this time, the two fixing blocks can clamp the sliding frame, so that multiple electrode sheets are in the same position during the stacking process, avoiding the electrode sheet position shift and causing misalignment of multi-layer electrode sheets, effectively improving the accuracy of multi-layer electrode sheet stacking.

[0017] 3. This invention proposes an automatic lithium battery stacking machine. During the calibration process, airflow enters the interior of the protective box to move the calibration block. At the same time, some airflow is blown out from the air outlet on the calibration block, which can remove dust from the electrode sheets. The blown-out impurities can be collected into the collection box by activating the exhaust fan for centralized processing. At this time, the air outlet is close to the electrode sheets, which can more quickly clean the impurities on the surface of the electrode sheets, improve the dust removal efficiency, and enhance the dust removal effect. This avoids some impurities adhering to the electrode sheets from affecting product quality, and effectively improves product quality.

[0018] 4. This invention proposes an automatic lithium battery cutting and stacking machine. It features a shaping mechanism where a cylinder moves the electrode sheet into the heating chamber and places it on the separator. A coating roller moves to the surface of the electrode sheet or separator to apply adhesive. After coating, a heating fan blows hot air into the fixing box and out through heating holes, preheating the adhesive on the electrode sheet. Simultaneously, a first electric slide rail moves a second electric slide rail and a fixing frame via a mounting base. The fixing frame moves a second cylinder via a fixing plate, which in turn moves a pressure plate. An electric heater heats the pressure plate. When the pressure plate reaches the top of the electrode sheet, it hot-presses the electrode sheet. Combined with the preheating of the adhesive by the hot air from the heating fan, the adhesive can be quickly cured into a single unit, effectively saving curing time and improving work efficiency. Furthermore, each electrode sheet is squeezed by the pressure plate, ensuring the adhesive is evenly distributed on the surface of the electrode sheet, thus improving the battery's performance.

[0019] 5. This invention proposes an automatic lithium battery stacking machine. By setting a separation mechanism, after the last layer is stacked, a second cylinder drives a pressure plate downwards to hot-press the multi-layer electrode sheets. A portion of the hot air blown into the fixing box by a heating fan enters the air supply pipe and then the positioning box. The hot air in the positioning box enters the heating tube, and the hot air in the heating tube is sprayed onto the surface of the heat-conducting block. The heat is transferred to the cutter. At this time, a fifth cylinder drives the heat-conducting block downwards. A second electric slide rail drives the fifth cylinder to move via the positioning frame. The fifth cylinder drives the cutter to hot-cut the separator via the heat-conducting block, allowing the separator to be heat-sealed. This prevents the electrode sheets from slipping and sliding out during multi-layer stacking, effectively improving the product quality of the electrode sheets. Attached Figure Description

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figure 1-8As shown, an automatic lithium battery cutting and stacking machine includes a frame 1 and a control frame 2. An integration mechanism 3 is provided inside the frame 1. The integration mechanism 3 includes an electric lifting slide rail 301. A lifting slide seat 302 is slidably connected to the outer surface of the electric lifting slide rail 301. A cutting machine 303 is slidably connected to the surface of the lifting slide seat 302. A first conveyor belt 304 is installed on the surface of the frame 1. An electric conveying slide rail 305 is fixedly connected to the inner surface of the frame 1. A conveying slide seat 306 is slidably connected to the outer surface of the electric conveying slide rail 305. A first cylinder 307 is fixedly connected to the surface of the conveying slide seat 306. A lifting frame 308 is fixedly connected to the output end of the first cylinder 307. A sliding frame 309 is slidably connected to the lower surface of the lifting frame 308. A plurality of suction cups 310 are connected to the lower surface of the sliding frame 309.

[0032] The effect is as follows: the electrode sheet is placed on the surface of the first conveyor belt 304, and the lifting slide seat 302 is moved by the electric lifting slide rail 301. The lifting slide seat 302 drives the cutting machine 303 to cut the electrode sheet. The electric conveying slide rail 305 drives the conveying slide seat 306 to move to a position above the cut electrode sheet. The first cylinder 307 drives the lifting frame 308 to move downward. The lifting frame 308 drives the sliding frame 309 to move downward, so that multiple suction cups 310 come into contact with the electrode sheet. At this time, the airflow is drawn to create a negative pressure around the suction cups 310, which adsorbs the electrode sheet.

[0033] like Figure 1-8 As shown, the frame 1 is also equipped with a correction mechanism 4. The correction mechanism 4 includes a heating box 401 and an air inlet pipe 402. The inner surface of the heating box 401 is symmetrically provided with protective boxes 403. The surfaces of the two protective boxes 403 are slidably connected with correction blocks 404. The surfaces of the two correction blocks 404 are fixedly connected with fixing blocks 405. Multiple springs 406 are provided between the two protective boxes 403 and the correction blocks 404. The air inlet pipe 402 is connected to the protective box 403. An air pump 8 is installed on the outer surface of the heating box 401. The air inlet end of the air pump 8 is connected to an air extraction pipe 9. The other end of the air extraction pipe 9 is connected to the sliding frame 309. The surface of the sliding frame 309 is provided with a limit block 10. The lower surface of the lifting frame 308 is provided with a limit groove. The limit block 10 is slidably connected to the limit groove. The air inlet pipe 402 is connected to the air outlet end of the air pump 8.

[0034] The effect is that when the electrode sheet is transported to the inlet of the heating box 401, the air pump 8 blows airflow, which enters the air inlet pipe 402 and then into the interior of the two protective boxes 403. The airflow pushes the corrector block 404 to move towards the position of the sliding frame 309. The fixing block 405 on the surface of the corrector block 404 contacts the sliding frame 309, which can push the sliding frame 309 to move. At this time, the two fixing blocks 405 can clamp the sliding frame 309, so that the electrode sheet is in the same position each time it is stacked.

[0035] like Figure 1-8 As shown, the rack 1 is also equipped with a cleaning mechanism 5. The cleaning mechanism 5 includes a collection box 501. The surface of the collection box 501 is provided with multiple air inlets. One of the positive blocks 404 is provided with an air outlet. An exhaust fan 502 is installed on the surface of the collection box 501. Another collection box 501 is fixedly connected to the collection box 501.

[0036] The effect is that during the calibration process, the airflow blows towards the calibration block 404, causing the calibration block 404 to move. At the same time, some airflow is blown out from the air outlet, which can remove dust from the electrode plate. The blown-out impurities can be collected into the collection box 501 by activating the exhaust fan 502 for centralized processing. At this time, the air outlet is close to the electrode plate, which can more quickly clean the impurities on the surface of the electrode plate, improve the dust removal efficiency, and enhance the dust removal effect, thus preventing some impurities attached to the electrode plate from affecting product quality.

[0037] like Figure 1-8 As shown, the frame 1 is also equipped with a shaping mechanism 6. The shaping mechanism 6 includes a first electric slide rail 601. The outer surface of the first electric slide rail 601 is slidably connected to a mounting base 602. The outer surface of the mounting base 602 is fixedly connected to a second electric slide rail 603 and a fixing frame 604. The outer surface of the fixing frame 604 is fixedly connected to a fixing plate 605. The lower surface of the fixing plate 605 is fixedly connected to a second cylinder 606. The output end of the second cylinder 606 is fixedly connected to a pressure plate 607. The inner surface of the pressure plate 607 is fixedly connected to an electric heater 608. The surface of the second electric slide rail 603 is slidably connected to a positioning frame 609. The inner surface of the heating box 401 is symmetrically provided with fixing boxes 610. Heating holes are opened on the outer surface of opposite sides of the fixing boxes 610. Heating fans 611 are fixedly connected to the surfaces of both fixing boxes 610.

[0038] The effect is that the heating fan 611 drives hot airflow into the interior of the fixing box 610 and blows it out from the heating hole. At this time, the adhesive on the electrode sheet can be preheated. Simultaneously, the first electric slide rail 601 drives the mounting base 602 to slide. The mounting base 602 drives the second electric slide rail 603 and the fixing frame 604 to move. The fixing frame 604 drives the fixing plate 605 to move. The fixing plate 605 can drive the second cylinder 606 to move. The second cylinder 606 drives the pressure plate 607 to move. At this time, the electric heater 608 can be turned on to heat the pressure plate 607. When the pressure plate 607 moves to the top of the electrode sheet, the electrode sheet can be hot-pressed to solidify it into one piece. By preheating the adhesive on the electrode sheet, the curing time can be saved.

[0039] like Figure 1-8 As shown, the frame 1 also includes a separation mechanism 7. The separation mechanism 7 includes a heat-conducting block 701, with a cutter 702 fixedly connected to the lower surface of the heat-conducting block 701. A gas supply pipe 703 is connected to the surface of one of the fixing boxes 610, and a positioning box 704 is connected to the other end of the gas supply pipe 703. A heating pipe 705 is connected to the lower surface of the positioning box 704, and the other end of the heating pipe 705 contacts the heat-conducting block 701. The positioning box 704 is fixedly connected to the positioning frame 609. A third cylinder 11 and a fourth cylinder 12 are fixedly connected to the inner surface of the frame 1. The output ends of the third cylinder 11 and the fourth cylinder 12 are respectively fixedly connected to a third electric slide rail 13 and a fourth electric slide rail 12. Electric slide rail 14, the surface of the third electric slide rail 13 is slidably connected to a glue-applying roller 15, the surface of the fourth electric slide rail 14 is slidably connected to a diaphragm roller 16, the upper surface of the frame 1 is fixedly connected to a second conveyor belt 17, the heating box 401 is fixedly connected to the frame 1, the electric lifting slide rail 301, the electric conveying slide rail 305 and the first conveyor belt 304 are all fixedly installed on the surface of the control frame 2, the heating box 401 is fixedly connected to the collection box 501 and the first electric slide rail 601 respectively, the first electric slide rail 601 is fixedly connected to the inner surface of the heating box 401, the lower surface of the positioning frame 609 is fixedly connected to a fifth cylinder, and the output end of the fifth cylinder is fixedly connected to the heat-conducting block 701.

[0040] The effect is that during the hot pressing process, some of the hot air enters the interior of the air supply pipe 703 and then the interior of the positioning box 704. The hot air in the positioning box 704 enters the heating pipe 705, and the hot air in the heating pipe 705 is sprayed onto the surface of the heat-conducting block 701. The heat is transferred to the cutter 702. At this time, the fifth cylinder drives the heat-conducting block 701 to move downward. The second electric slide rail 603 drives the positioning frame 609 to move. The positioning frame 609 drives the fifth cylinder to move. The fifth cylinder drives the heat-conducting block 701 to move. The heat-conducting block 701 drives the cutter 702 to perform hot cutting on the diaphragm, so that the diaphragm can be sealed by heat, avoiding the phenomenon of electrode slippage caused by multi-layer stacking.

[0041] Working principle: The fourth electric slide rail 14 is activated, driving the diaphragm roller 16 to move. A diaphragm is laid on the surface of the second conveyor belt 17, and the electrode sheet is placed on the surface of the first conveyor belt 304. The electric lifting slide rail 301 drives the lifting sliding seat 302 to move. The lifting sliding seat 302 drives the cutting machine 303 to cut the electrode sheet. The electric conveying slide rail 305 drives the conveying sliding seat 306 to move to a position above the cut electrode sheet. The first cylinder 307 drives the lifting frame 308 to move downward. The lifting frame 308 drives the sliding frame 309 to move downward, so that multiple suction cups 310 come into contact with the electrode sheet. At this time, the air pump 8 is activated to draw airflow, creating negative pressure around the suction cups 310, which adsorbs the electrode sheet. The electrode sheet is moved to the opening at the top of the heating box 401 by the electric conveyor slide rail 305, and then moved downward by the cylinder. At this time, it can be placed on the second conveyor belt 17. By activating the fourth electric slide rail 14, the diaphragm on the diaphragm roller 16 can be covered on the electrode sheet, and then the next electrode sheet is transported for stacking. The diaphragm roller 16 repeatedly diaphragms the surface of the electrode sheet, which can quickly stack multiple electrode sheets and improve stacking efficiency. When the electrode sheet is transported to the entrance of the heating box 401, the air pump 8 blows air, which enters the air inlet pipe 402 and then into the interior of the two protective boxes 403. The airflow pushes the corrector block 404 to move towards the position of the sliding frame 309. The fixing block 405 on the surface of the corrector block 404 and the sliding frame 309 are connected. When the movable frame 309 contacts, it can push the sliding frame 309 to move. At this time, the two fixed blocks 405 can clamp the sliding frame 309, ensuring that the electrode sheets are in the same position each time they are stacked, avoiding displacement of the electrode sheets and causing misalignment of multi-layer electrode sheets, thus improving the accuracy of multi-layer electrode sheet stacking. During the calibration process, the airflow blows towards the calibration block 404, causing the calibration block 404 to move. At the same time, some airflow is blown out from the air outlet, which can remove dust from the electrode sheets. The blown-out impurities can be collected into the collection box 501 by activating the exhaust fan 502 for centralized treatment. At this time, the air outlet is close to the electrode sheets, which can more quickly clean the impurities on the surface of the electrode sheets, improving the dust removal efficiency. This improves efficiency and dust removal, preventing impurities on the electrode sheets from affecting product quality. When the electrode sheets are placed on the diaphragm, the adhesive roller 15 on the surface of the third electric slide rail 13 moves to the surface of the electrode sheet or diaphragm, where adhesive can be applied. After application, the height of the adhesive roller 15 can be adjusted by the third cylinder 11. After application, the heating fan 611 drives hot airflow into the fixing box 610 and blows it out through the heating hole, preheating the adhesive on the electrode sheets. Simultaneously, the first electric slide rail 601 drives the mounting base 602 to slide, the mounting base 602 drives the second electric slide rail 603 and the fixing frame 604 to move, and the fixing frame 604 drives the fixing plate 605 to move.The fixed plate 605 can drive the second cylinder 606 to move, and the second cylinder 606 drives the pressure plate 607 to move. At this time, the electric heater 608 can be turned on to heat the pressure plate 607. When the pressure plate 607 moves to the top of the electrode sheet, it can hot press the electrode sheet to solidify it into one piece. By preheating the adhesive on the electrode sheet, the curing time can be saved and the work efficiency can be improved. After the last layer is stacked, during the hot pressing process, some of the hot air enters the interior of the air supply pipe 703 and enters the positioning box 704. Inside the positioning box 704, hot air flows into the heating tube 705. The hot air from the heating tube 705 is then sprayed onto the surface of the heat-conducting block 701, transferring heat to the cutter 702. At this time, the fifth cylinder moves the heat-conducting block 701 downwards. The second electric slide rail 603 moves the positioning frame 609, which in turn moves the fifth cylinder. The fifth cylinder then moves the heat-conducting block 701, which in turn moves the cutter 702 to thermally cut the diaphragm. This allows the diaphragm to be heat-sealed, preventing electrode slippage caused by multi-layer stacking.
