Description

Technical Field

[0001] This invention relates to the field of electrode processing technology, and in particular to an integrated electrode die-cutting and slitting machine. Background Technology

[0002] like Figure 23 As shown, this is a traditional electrode strip. The two sides of its width are empty foil areas, which are also the electrode tab cutting areas. When processing the electrode, the electrode tab outline is cut out in the electrode tab cutting areas on both sides of the electrode strip. Waste is generated on both sides, resulting in a large material loss, especially for large electrodes (the electrode tab is higher, which means that the width of the empty foil area is larger). After the electrode tab is cut, it is necessary to cut and divide it in the middle of the width direction of the electrode strip to realize the two-in-one processing of the electrode strip (forming the first electrode and the second electrode). This means that at least three laser cutting mechanisms need to be set up in the same processing equipment, which increases the production cost.

[0003] like Figure 24 As shown, the improved electrode strip E has its empty foil area, i.e., the tab E3 cutting area, located at the center of the width of the electrode strip E. After processing the tab E3, intermediate waste is generated. During the first cut, a complete first electrode E1 and intermediate body E2 can be formed. During the second cut, a complete second electrode E21 and waste strip E22 can be formed, thus completing the two-part processing of the electrode strip E. This can be achieved by setting up two laser cutting mechanisms. For processing large tabs E3, especially electrode strip E with a tab height exceeding 40mm, this not only saves processing equipment costs but also reduces foil waste.

[0004] However, for large tabs, while their height increases, their thickness remains the same, making them more prone to folding during conveyor belt transport. Simultaneously, the number of notches per unit length on the scrap belt caused by cutting the tabs is greater, resulting in weaker overall strength of the scrap belt, making it susceptible to vibration, breakage, and entanglement with the electrode sheets. This necessitates that the conveyor belt speed for both the electrode sheet material and the processed electrode sheets should not be too high during processing; in other words, a lower conveyor speed should be maintained to avoid the aforementioned problems. However, a lower conveyor speed, in turn, reduces production efficiency. Summary of the Invention

Detailed Implementation

[0030] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Please refer to Figures 1 to 22 A type of integrated die-cutting and slitting machine for electrode tabs, used in applications such as... Figure 24 The improved electrode strip E processing shown includes an integrated electrode tab die-cutting and slitting machine comprising a frame 1, on which an unwinding area A, a slitting area B, a detection area C, and a rewinding area D are sequentially arranged. Within the unwinding area A, along the travel path of the electrode strip E, an unwinding roller group 2, an adhesive application mechanism 3, and a pressure roller mechanism 4 are sequentially arranged. A strip-connecting mechanism 5 is located within the unwinding area A near the unwinding roller group 2. Figure 1 and Figure 2 As shown, there are two unwinding roller groups 2. The strip splicing mechanism 5 enables the splicing of the electrode strips E on the two unwinding roller groups 2 to achieve uninterrupted production. The adhesive application mechanism 3 is used to apply adhesive to the seam of the electrode strips E to improve the splicing strength. The pressure roller mechanism 4 is used to roll the tab cutting area on the electrode strips E to improve the strength of the foil in this area. This ensures that after the tabs E3 are cut and formed in the tab cutting area, the tabs E3 have high strength and are not prone to folding.

[0033] Furthermore, the dividing area B is provided with a correction mechanism 6 and a cutting mechanism 7 from top to bottom. The cutting mechanism 7 is used to cut the electrode strip E into a first electrode E1 and a second electrode E21. The first electrode E1 is located on the upper side of the second electrode E21. The detection area C is provided with a first roller C1 corresponding to the first electrode E1 and a second roller C2 corresponding to the second electrode E21. The wrap angle of the first electrode E1 on the first roller C1 is 60°-80°, and the wrap angle of the second electrode E21 on the second roller C2 is 60°-80°. In this embodiment, in the detection zone C, the first electrode E1 and the second electrode E21 need to undergo pre-winding preparation work such as electrode tab E3 detection and electrode dust removal. Preferably, the outer diameters of the first roller C1 and the second roller C2 are the same and both are greater than 150mm. Setting the wrap angle to 60°-80° can shorten the length of the detection zone C while ensuring that the electrode tab E3 does not fold at the roller. Under this premise, the belt speed of the electrode material E, i.e. the first electrode E1 and the second electrode E21, can be increased, which is conducive to improving production efficiency.

[0034] Preferably, the wrap angle of the first electrode E1 on the first guide roller C1 is 70°, and the wrap angle of the second electrode E21 on the second guide roller C2 is 70°. This electrode lug die-cutting and slitting integrated machine can achieve a conveyor speed of 100m / min while ensuring processing quality.

[0035] It should be noted that there are multiple first guide rollers C1 and second guide rollers C2, and the specific number can be determined according to the inspection items in the layout of the inspection area C. Optionally, in order to further ensure that the tab E3 does not fold during the belt conveyor process, two tab E3 support plates are arranged in a mirror image between two adjacent first guide rollers C1 and two adjacent second guide rollers C2 to smooth and limit the tab E3 on both sides to prevent folding.

[0036] Furthermore, at least one threaded roller 11 is provided on the frame 1, and the threaded roller 11 is located upstream of the cutting mechanism 7. The threaded roller 11 is used to spread the electrode strip E to both sides in its width direction, preventing collapse and wrinkles in the empty foil area in the middle, and ensuring the processing quality of the electrode tab E3.

[0037] In this embodiment, the adhesive application mechanism 3 and the correction mechanism 6 are existing technologies. The correction mechanism 6 is used to correct the deviation of the electrode strip E during the conveying process. The specific structure of the adhesive application mechanism 3 and the correction mechanism 6 will not be described in detail here.

[0038] like Figures 3 to 5As shown, the tape receiving mechanism 5 includes an unwinding and material changing assembly 51. The unwinding and material changing assembly 51 includes a first support plate 511 mounted on the frame 1, which is parallel to the horizontal plane. A first mounting plate 512 is provided on the first support plate 511. The first mounting plate 512 can be close to or away from the unwinding roller group 2. A long cutting roller structure 513 that can move along the width direction of the electrode strip E is provided on the first mounting plate 512. In this embodiment, the first mounting plate 512 is located below the first support plate 511. Two first connecting plates 5121 are provided on the first mounting plate 512. The two first connecting plates 5121 are correspondingly arranged on both sides of the first support plate 511. One of the first connecting plates 5121 is slidably connected to the first support plate 511 through a slide rail slider assembly. A first linear module 5111 is provided on the first support plate 511, and the other first connecting plate 5121 is assembled to the first linear module 5111. In use, the first linear module 5111 drives the first mounting plate 512 to move relative to the first support plate 511 via the first connecting plate 5121. Further, the long cutting roller structure 513 is slidably mounted on the lower side of the first mounting plate 512 via a slide rail slider assembly and is driven by a first rodless cylinder 5122 disposed on the first mounting plate 512.

[0039] In this embodiment, the direction of movement of the first mounting plate 512 relative to the first support plate 511 is perpendicular to the width direction of the electrode strip E, and both are parallel to the horizontal plane. When splicing is required, the long cutting roller structure 513 moves along the width direction of the electrode strip E towards the electrode strip E to between the two unwinding roller groups 2. Then, through the movement of the first mounting plate 512 relative to the first support plate 511, the long cutting roller structure 513 can drive and adhere the electrode strip E on one of the unwinding roller groups 2 to the electrode strip E on the other unwinding roller group 2, thereby achieving adhesion and splicing. This process requires no manual intervention, which helps to improve the splicing speed and overall production efficiency.

[0040] like Figures 5 to 7As shown, the long cutting roller structure 513 includes a first roller 5131 and a cutter assembly 5132. The axial direction of the first roller 5131 is parallel to the width direction of the electrode strip E. The first roller 5131 can rotate around its central axis, and the cutter assembly 5132 can move along the axial direction of the first roller 5131. When the long cutting roller structure 513 is in the cutting state, the cutter assembly 5132 at least partially passes through the side wall of the first roller 5131 and extends out of the side wall of the first roller 5131. When the long cutting roller structure 513 is in the non-cutting state, the cutter assembly 5132 retracts towards the inner side wall of the first roller 5131 compared to the cutter assembly 5132 when the long cutting roller structure 513 is in the cutting state. This design allows the cutter assembly 5132 to retract when not cutting, improving safety. Simultaneously, the rotatable design of the first roller 5131 allows it to reduce or even eliminate sliding friction between itself and the electrode strip E during operation, further enhancing safety.

[0041] Specifically, the long cutting roller structure 513 further includes a first support seat 5133, which is adjustablely disposed on the first mounting plate 512 along the width direction of the electrode strip E. In this embodiment, the first support seat 5133 is slidably mounted on the first mounting plate 512 via a slide rail slider assembly and is driven by a first rodless cylinder 5122 mounted on the first mounting plate 512. Furthermore, a swing arm shaft 5134 is rotatably mounted on the first support base 5133, and a guide seat 5135 is mounted on the swing arm shaft 5134. The guide seat 5135 extends along the width direction of the electrode strip E. A roller end cap 5137 is disposed at the free end of the guide seat 5135. One end of the first roller 5131 is mounted on the swing arm shaft 5134, and the other end of the first roller 5131 is mounted on the roller end cap 5137. The first roller 5131 is sleeved outside the guide seat 5135. A knife groove 51311 is provided through the side wall of the first roller 5131, and the knife groove 51311 extends along the width direction of the electrode strip E. Furthermore, a first driving member 51331 is disposed on the swing arm shaft 5134. The first driving member 51331 is used to drive the cutting blade assembly 5132 to move along the width direction of the electrode strip E. Preferably, the first driving component 51331 is a motor, which drives the swing arm shaft 5134 to rotate via a synchronous belt, thereby rotating the first roller 5131. The cutting blade assembly 5132 extends out of the first roller 5131 or retracts into the first roller 5131 through the cutting groove 51311. When cutting the electrode strip E, the cutting blade assembly 5132 moves along the cutting groove 51311. After cutting, the long cutting roller structure 513 moves along the width direction of the electrode strip E towards the frame 1, that is, away from the electrode strip E.

[0042] like Figures 7 to 9As shown, the cutter assembly 5132 includes a cutter connecting seat 51321 and a cutter fixing seat 51322. The cutter fixing seat 51322 is slidably connected to the cutter connecting seat 51321, and a blade 51323 is mounted on the cutter fixing seat 51322. The guide seat 5135 is provided with a first guide groove a and a second guide groove b. The cutter connecting seat 51321 is provided with a first cam bearing follower 51324 adapted to the first guide groove a, and the cutter fixing seat 51322 is provided with a first cam bearing follower 51324 adapted to the second guide groove b. The second cam bearing follower 51325; the first guide groove a extends along the width direction of the electrode strip E, and the second guide groove b includes a first groove segment b1 and a second groove segment b2 that are interconnected. The extension direction of the first groove segment b1 is parallel to the extension direction of the first guide groove a. When the second cam bearing follower 51325 moves in the first groove segment b1, the long cutting roller structure 513 is in a cutting state; when the second cam bearing follower 51325 moves in the second groove segment b2, the long cutting roller structure 513 is in a non-cutting state. In this embodiment, a second rodless cylinder 5136 is mounted on the swing arm shaft 5134, and the cutter assembly 5132 is mounted on the guide seat 5135 and driven by the second rodless cylinder 5136. Specifically, the cutter connecting seat 51321 is connected to the second rodless cylinder 5136. In this way, the cutting motion and the retraction and release motion of the cutter assembly 5132 can be linked.

[0043] like Figure 8 As shown, the second groove segment b2 is positioned close to the swing arm shaft 5134. In the width direction of the electrode strip E, the second cam bearing follower 51325 is closer to the swing arm shaft 5134 than the first cam bearing follower 51324. That is, when the second cam bearing follower 51325 enters the second groove segment b2, the first cam bearing follower 51324 still has room to move within the first guide groove a, ensuring smooth movement of the second cam bearing follower 51325 within the second groove segment b2 to complete the complete blade retraction and extension 51323 action. It should be noted that the blade retraction 51323 action is achieved the instant the second cam bearing follower 51325 enters the second groove segment b2 from the first groove segment b1. As the cutter connecting seat 51321 continues to move towards the swing arm shaft 5134, the blade retraction 51323 action is further achieved.

[0044] In this embodiment, preferably, the second groove segment b2 is arc-shaped.

[0045] like Figure 9As shown, a cutter guide shaft 51326 is mounted on the cutter fixing seat 51322. The cutter guide shaft 51326 is slidably connected to the cutter connecting seat 51321. A return spring 51327 is sleeved on the cutter guide shaft 51326, and the return spring 51327 is located between the cutter connecting seat 51321 and the cutter fixing seat 51322. The first driving member 51331 acts on the cutter connecting seat 51321. The return spring 51327 facilitates the release of the blade 51323. Specifically, when the second cam bearing follower 51325 moves from the second groove section b2 to the first groove section b1, the return spring 51327 acts on the cutter fixing seat 51322 so that the blade 51323 can smoothly extend from the cutter groove 51311.

[0046] like Figure 9 As shown, a third guide groove 51328 is provided on the cutter connecting seat 51321, and a guide block 51329 adapted to the third guide groove 51328 is provided on the cutter fixing seat 51322. The extension direction of the third guide groove 51328 is parallel to the axial direction of the cutter guide shaft 51326. The guide block 51329 is slidably embedded in the third guide groove 51328, and the second cam bearing follower 51325 is installed on the guide block 51329.

[0047] like Figure 3 and Figure 10 As shown, the tape receiving mechanism 5 also includes an unwinding and adhesive applicator assembly 52. ​​The unwinding and adhesive applicator assembly 52 includes a second mounting plate 521, on which a second driving member 522 is mounted. A third mounting plate 523 is disposed on the second driving member 522. The second driving member 522 acts on the third mounting plate 523, enabling the third mounting plate 523 to move along the width direction of the electrode strip E. A mounting base 524 is rotatably mounted on the third mounting plate 523, and an unwinding and adhesive applicator is movably mounted on the mounting base 524. Here, the unwinding and adhesive applicator can be any existing double-sided adhesive applicator. The mounting base 524 is rotatably connected to the third mounting plate 523 via a rotary cylinder. The unwinding and adhesive applicator is movably assembled with the mounting base 524 via a linear module. Specifically, the unwinding and adhesive applicator can move closer to or further away from the unwinding roller group 2. The rotatable mounting of the mounting base 524 and the third mounting plate 523 enables the unwinding and adhesive applicator to apply adhesive to both unwinding roller groups 2.

[0048] In summary, during the splicing process, firstly, double-sided tape is applied to the electrode strip E on one of the unwinding roller groups 2 through the unwinding and adhesive application assembly 52. ​​Then, the electrode strip E on the other unwinding roller group 2 is driven onto the electrode strip E with the double-sided tape applied through the long cutting roller structure 513, so that the two electrode strips E are bonded together. Finally, the electrode strip E driven by the long cutting roller structure 513 is cut by the blade 51323.

[0049] Understandably, the roll on the unwinding roller group 2 with double-sided tape is a spare roll, while the electrode strip E on the other unwinding roller group 2 is being used in the electrode tab die-cutting and slitting machine and is about to run out. Specifically... Figure 11 As shown.

[0050] like Figures 12 to 15 As shown, the cutting mechanism 7 includes a roller assembly 71, an upper cutting assembly 72, and a lower cutting assembly 73. The roller assembly 71 includes two cutting plates 711 spaced apart along the width direction of the electrode strip E. A first cutting roller 712, a second cutting roller 713, a third cutting roller 714, and a fourth cutting roller 715 are arranged sequentially from top to bottom between the two cutting plates 711. The area between the first cutting roller 712 and the second cutting roller 713 constitutes the upper cutting area 71a, and the area between the third cutting roller 714 and the fourth cutting roller 715 constitutes the lower cutting area 71b. The upper cutting assembly 72 is located near the upper cutting area 71a, and the lower cutting assembly 73 is located near the lower cutting area 71b. The upper cutting assembly 72 is used to cut the electrode strip E to form a first electrode E1 and an intermediate body E2, and the lower cutting assembly 73 is used to cut the intermediate body E2 to form a second electrode E21 and a waste strip E22. In this embodiment, the first cutting roller 712 is a threaded roller 11, used to flatten the electrode strip E in the width direction to prevent wrinkles from appearing in the upper cutting area 71a, thus ensuring the cutting accuracy of the first electrode E1 and the intermediate body E2. Optionally, the fourth cutting roller 715 is an adsorption roller, used to tension the intermediate body E2 and facilitate the smooth transport of the second electrode E21.

[0051] In this embodiment, the electrode strip E is tensioned between the first cutting roller 712 and the second cutting roller 713, and the first electrode E1 extends from the area between the second cutting roller 713 and the third cutting roller 714 toward the detection area C; the intermediate body E2 is tensioned between the third cutting roller 714 and the fourth cutting roller 715, and the second electrode E21 extends from the area below the fourth cutting roller 715 toward the detection area C; a waste tube 74 is disposed below the fourth cutting roller 715, and the waste strip E22 extends into the waste tube 74.

[0052] Specifically, such as Figure 14 As shown, the cutting mechanism 7 also includes a machine base 70 mounted on the frame 1, and the roller assembly 71, the upper cutting assembly 72, the lower cutting assembly 73, and the waste pipe 74 are all mounted on the machine base 70.

[0053] like Figure 12 , Figure 14 and Figure 16As shown, the upper cutting assembly 72 includes an upper galvanometer structure 721 and an upper fixing structure 722. The upper fixing structure 722 includes an upper guide rail plate 7221. A first adsorption plate 7222 and a second adsorption plate 7223 are sequentially arranged on the upper guide rail plate 7221 from top to bottom. The first adsorption plate 7222 and the second adsorption plate 7223 are used to adsorb the electrode strip E. The upper galvanometer structure 721 generates a first laser beam 7211, which is projected onto the area of ​​the electrode strip E between the first adsorption plate 7222 and the second adsorption plate 7223. During the conveying of the electrode strip E, the first adsorption plate 7222 and the second adsorption plate 7223 can cooperate with each other to tension the electrode strip E in the upper cutting area 71a, thereby facilitating the precise cutting of the electrode strip E into the first electrode E1 and the intermediate body E2.

[0054] Furthermore, the upper fixed structure 722 also includes an upper belt frame 7224, on which at least two parallel first belt rollers 72241 are rotatably mounted. The at least two first belt rollers 72241 are linked by a first support belt 72242, and the axial direction of the first belt rollers 72241 is parallel to the width direction of the electrode material strip E. There are multiple first support belts 72242, which are spaced apart along the axial direction of the first belt rollers 72241. A second adsorption plate 7223 is disposed on the upper belt frame 7224 and is located between the two first belt rollers 72241 close to the electrode material strip E. The electrode material strip E is attached to the first support belt 72242, and the first support belt 72242 is located between the second adsorption plate 7223 and the electrode material strip E. A third driving member 7225 for driving the first belt rollers 72241 to rotate is disposed on the upper belt frame 7224. In this embodiment, optionally, there are four first belt rollers 72241, and the third driving component 7225 is a motor that drives one of the first belt rollers 72241. Then, all four first belt rollers 72241 linked by the first support belt 72242 can rotate synchronously. During use, the speed of the first support belt 72242 is the same as the speed of the electrode material strip E. The negative pressure of the second adsorption plate 7223 causes the electrode material strip E, specifically, the area of ​​the tab E3 on the first electrode E1 and the empty foil area on the intermediate body E2 used for processing the tab E3, to adhere to the first support belt 72242 and move synchronously with it. This ensures that the tab E3 does not fold during the conveying of the first electrode E1, and that the empty foil area on the intermediate body E2 used for processing the tab E3 does not fold or wrinkle during the conveying process. This helps to increase the belt speed of the electrode material strip E, thereby improving production efficiency.

[0055] like Figure 1 and Figure 17As shown, a first negative pressure chamber 72243 is disposed within the upper belt frame 7224. A first negative pressure port 72244, communicating with the first negative pressure chamber 72243, is disposed on the side wall of the upper belt frame 72244. A second adsorption plate 7223 and at least one first belt roller 72241 are disposed at the first negative pressure port 72244. An adsorption hole 72231 is provided through the second adsorption plate 7223. A first belt roller brush 72245 is disposed on the upper belt frame 7224, and the first belt roller brush 72245 abuts against the first belt roller 72241. In this embodiment, the first negative pressure chamber 72243 is connected to the negative pressure source 8, which, while providing adsorption force to the second adsorption plate 7223, can remove impurities cleaned from the first support belt 72242 by the first belt roller brush 72245.

[0056] like Figure 12 , Figures 18 to 21 As shown, the lower cutting assembly 73 includes a lower galvanometer structure 731 and a lower fixing structure 732. The lower fixing structure 732 includes a lower belt mounting plate 7321. Two lower belt supports 7322 are spaced apart from top to bottom on the lower belt mounting plate 7321. At least two parallel second belt rollers 73221 are rotatably mounted on the lower belt supports 7322. A third suction plate 73222 is provided on the lower belt supports 73222, and the third suction plate 73222 is located between the two second belt rollers 73221 near the intermediate body E2. The second belt rollers 73221 on the upper lower belt support 73222 are linked by a second support belt 73223, which is located on the third suction plate 73222. Between 22 and intermediate body E2; a waste discharge rack 7323 is rotatably mounted on the lower belt frame 7322 on the lower side, and a third belt roller 7324 is arranged at the lower end of the waste discharge rack 7323. The third belt roller 7324 is parallel to the second belt roller 73221, and the third belt roller 7324 and the second belt roller 73221 on the lower belt frame 7322 are linked through the third support belt 73224; a fourth adsorption plate 7325 is assembled on the waste discharge rack 7323, and the third support belt 73224 is located between the fourth adsorption plate 7325 and the waste belt E22; the waste discharge rack 7323 can rotate so that the third belt roller 7324 moves closer to or away from the fourth cutting roller 715.

[0057] In this embodiment, the structure of the lower belt frame 7322 is the same as that of the upper belt frame 7224.

[0058] In some embodiments, the second belt guide roller 73221 on the upper lower belt frame 7322 is driven by one motor, and the second belt guide roller 73221 on the lower lower belt frame 7322 is driven by another motor, ensuring that the second support belt 73223 and the third support belt 73224 have the same speed. In use, the empty foil area on the intermediate body E2 for processing the tab E3 (composed of the waste strip E22 and the tab E3 of the second electrode E21) is attached to the second support belt 73223. The tab E3 of the second electrode E21 is processed in the area between the two lower belt frames 7322 to separate the tab E3 of the second electrode E21 from the waste strip E22. Subsequently, the waste strip E22 is attached to the third support belt 73224 and moves downward to the waste pipe 74 for recycling, while the second electrode E21 passes around the fourth cutting roller 715 and enters the detection area C. In this embodiment, the lower belt frame 7322 and the waste material rack 7323 on the lower side can effectively fix and transport the waste belt E22, preventing it from shaking or spinning during transport and affecting the cutting of the upper tab E3 of the second electrode plate E21. This can be used in high-speed belt conveyor processing scenarios, which is beneficial to improving production efficiency.

[0059] In this embodiment, the angle of the waste discharge rack 7323 can be adaptively adjusted according to the specifications of the waste belt E22 to adjust the distance between the third belt roller 7324 and the fourth cutting roller 715, thereby better separating the second electrode plate E21 and the waste belt E22.

[0060] In this embodiment, the second belt guide roller 73221 and the third belt guide roller 7324 on the upper lower belt frame 7322 are linked by a fourth support belt 73225. Because the third belt guide roller 7324 and the second belt guide rollers 73221 on the two lower belt frames 7322 are linked, as... Figure 18 As shown, by mounting a motor on the lower belt mounting plate 7321, the second belt roller 73221 and the third belt roller 7324 can be driven, and the second support belt 73223, the third support belt 73224 and the fourth support belt 73225 can move synchronously to achieve the same speed, which facilitates the same speed conveying of the intermediate body E2, or the second pole piece E21 and the waste belt E22.

[0061] In this embodiment, there are multiple second support belts 73223 and multiple third support belts 73224, and the multiple second support belts 73223 and multiple third support belts 73224 are all spaced apart along the axial direction of the second belt roller 73221.

[0062] The lower galvanometer structure 731 generates a second laser beam 7311, which is projected onto the area of ​​the intermediate body E2 between the two lower belt frames 7322.

[0063] In some embodiments, such as Figure 18 and Figure 19 As shown, a waste tension roller 7326 is installed on the waste discharge rack 7323, and the waste belt E22 is located between the waste tension roller 7326 and the third support belt 73224. Here, the waste tension roller 7326, in conjunction with the fourth adsorption plate 7325, can better limit the waste belt E22 and more effectively separate the waste belt E22 and the second electrode E21.

[0064] In some embodiments, the waste pipe 74 is connected to a negative pressure source 8 to generate negative pressure within the waste pipe 74, thereby improving the recycling of waste strip E22 and enhancing production safety.

[0065] like Figure 19 As shown, an adjusting plate 73231 is provided between the waste discharge rack 7323 and the lower belt conveyor 7322 located below it. The adjusting plate 73231 is hinged to the waste discharge rack 7323. The adjusting plate 73231 is provided with an adjusting slot 73232. The lower belt conveyor 7322 is provided with an adjusting pin 73226 adapted to the adjusting slot 73232. The adjusting pin 73226 is embedded in the adjusting slot 73232 and can move relative to the adjusting plate 73231. Specifically, the adjusting plate 73231 is used to stabilize the angle of the waste discharge rack 7323. During adjustment, the adjusting pin 73226 can slide within the adjusting slot 73232, and the adjusting plate 73231 can rotate relative to the adjusting pin 73226.

[0066] like Figure 14 As shown, the upper guide plate 7221 and the lower guide plate are mounted on the roller assembly 71 via a slide rail slider assembly, specifically between the two cutting vertical plates 711. That is, the upper fixing structure 722 and the lower fixing structure 732 can be adjusted in position between the two cutting vertical plates 711, or in other words, in the width direction of the electrode strip E, to adapt to processing requirements. Figure 12 and Figure 13As shown, it can be understood that the upper galvanometer structure 721 and the upper fixing mechanism are used together in the width direction of the electrode strip E; the lower galvanometer structure 731 and the lower fixing structure 732 are used together in the width direction of the electrode strip E, that is, the upper galvanometer structure 721 and the lower galvanometer structure 731 are both adjustablely mounted on the machine base 70 along the width direction of the electrode strip E. Preferably, both the upper galvanometer structure 721 and the lower galvanometer structure 731 are slidably connected to the machine base 70 via a slide rail slider assembly, and are driven by a linear module or a lead screw module mounted on the machine base 70 to move along the width direction of the electrode strip E. Further, the upper galvanometer structure 721 is connected to the upper fixed structure 722 via an upper connecting rod 75, and the lower galvanometer structure 731 is connected to the lower fixed structure 732 via a lower connecting rod 76, thereby enabling the linkage between the upper galvanometer structure 721 and the upper fixed structure 722 in the width direction of the electrode strip E, as well as the linkage between the lower galvanometer structure 731 and the lower fixed structure 732 in the width direction of the electrode strip E.

[0067] In this embodiment, the upper fixing structure 722 and the lower fixing structure 732 can adsorb and fix the empty foil area or the electrode tab E3 during the movement of the electrode strip E, thereby making the empty foil area and the electrode tab E3 stable under high-speed conveying, which can effectively avoid wrinkles in the empty foil area and folding of the electrode tab E3, which is conducive to improving production efficiency and ensuring product quality.

[0068] It should be noted that, as Figure 23 The traditional electrode strip E processing process shown can also be applied to this electrode tab die-cutting and slitting integrated machine. It is only necessary to adjust the position of the pressure roller mechanism 4, the upper cutting component 72 and the lower cutting component 73 in the width direction of the electrode strip E according to the position of the empty foil area during use. Similarly, because this electrode tab die-cutting and slitting integrated machine can effectively prevent the electrode tab E3 from flipping, it can create conditions for increasing the belt speed and thus improve production efficiency.

[0069] like Figure 22 As shown, the pressure roller mechanism 4 includes a support roller 41 mounted on the frame 1 and a pressure roller 45 disposed on the frame 1. The pressure roller 45 can be close to or away from the support roller 41, and the electrode strip E is located between the pressure roller 45 and the support roller 41. Several pressure protrusions 451 are arranged on the surface of the pressure roller 45. Optionally, the pressure protrusions 451 are spherical protrusions or strip-shaped protrusions. When the pressure protrusions 451 are strip-shaped protrusions, the pressure roller 45 can be a spur gear or a helical gear. The pressure roller 45, in conjunction with the support roller 41, pressures the tab cutting area, i.e., the empty foil area, on the electrode strip E. Under the action of the pressure protrusions 451, reinforcing ribs are formed in the empty foil area, thereby providing strength.

[0070] In this embodiment, a first cantilever 411 is provided on the frame 1, and a support roller 41 is rotatably mounted on the first cantilever 411. A second cantilever 42 is provided on the frame 1, and a cylinder is mounted on the free end of the second cantilever 42. A wheel frame 43 is mounted on the cylinder and is driven by the cylinder to move closer to or away from the support roller 41. A roller shaft 44 is mounted on the wheel frame 43, and a roller pressing roller 45 is rotatably mounted on the roller shaft 44.

[0071] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
