Description

[0018] 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.

[0019] 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.

[0020] 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.

[0021] Please refer to Figures 1 to 9A laser cutting and rewinding machine for electrodes includes a platform 200 mounted on a frame 100. An unwinding roller 300, a laser cutting module 400, a rewinding roller 500, and an electrode cutting module 600 are sequentially arranged on the platform 200 along a first direction X. Vertically, the rewinding roller 500 is lower than the electrode cutting module 600. The unwinding roller 300, laser cutting module 400, and electrode cutting module 600 are connected in series via a main guide roller group. The machine also includes a secondary guide roller group, which connects the main guide roller group and the rewinding roller 500. The connection point between the secondary and main guide roller groups is located between the laser cutting module 400 and the electrode cutting module 600. The main and secondary guide roller groups at least partially overlap. During operation, the electrode strip a is released from the unwinding roller 300 and then conveyed along the main guide roller group to the laser cutting module 400. The laser cutting module 400 laser-cuts the strip a to form electrode tabs. After laser cutting, the strip a can either continue to be conveyed along the main roller group to the electrode cutting module 600, where it is cut into individual electrode sheets and stored; or it can be conveyed via the auxiliary roller group to the winding roller 500, where the strip a with the electrode tabs cut is wound up and stored. Since the main roller group and the auxiliary roller group overlap at least partially, the strip a can choose different conveying paths after the laser cutting module 400 according to production needs, allowing for either cutting and sheet production or winding and storage of the strip a.

[0022] Thus, this integrated electrode laser cutting and rewinding machine combines unwinding, laser cutting, electrode cutting, and rewinding functions into one unit, enabling both electrode rewinding and storage and electrode cutting and forming to be performed on a single machine. Compared to existing technologies that require switching between different machines to achieve the two processing methods, the equipment in this embodiment can complete both processing methods on the same machine without switching the material rolls, significantly improving production efficiency, reducing production costs, and also reducing equipment footprint and investment costs.

[0023] It should be noted that the vertical winding roller 500 is lower than the electrode cutting module 600. This layout makes the horizontal distance between the laser cutting module 400 and the electrode cutting module 600 smaller, thereby improving the structural compactness of the electrode laser cutting and winding integrated machine and helping to reduce the size.

[0024] like Figure 2As shown, the main roller assembly includes an adjusting roller 701, a tension detection module 702, a first tension roller 703, an electrode tab reinforcing rib assembly 704, a first correction assembly 705, an electrode tab dust removal module 706, a main drive module 707, a second tension roller 708, and a buffer module 709 arranged sequentially along the conveying direction of the material belt a. Among them, in the conveying direction of the material belt a, at least one first roller shaft 710 is arranged between any two adjacent pairs of the tension detection module 702, the first tension roller 703, the electrode tab reinforcing rib assembly 704, the first correction assembly 705, the electrode tab dust removal module 706, the main drive module 707, the second tension roller 708, and the buffer module 709.

[0025] The adjusting roller 701 is used to adjust the initial position and posture of the unwound strip a, ensuring that strip a enters the subsequent station in the correct posture; the tension detection module 702 is used to detect the tension of strip a in real time, providing a basis for tension adjustment and control; the first tension roller 703 and the second tension roller 708, together with the main drive module 707, jointly realize the precise adjustment and control of the tension of strip a, ensuring that strip a maintains appropriate tension during the conveying process, avoiding excessive tension causing stretching and deformation of strip a or insufficient tension causing strip a to loosen and deviate; the tab reinforcing rib assembly 704 is used to form a reinforcing rib structure at the root of the tab, improving the strength of the tab. The first correction component 705 is used to correct the conveying position of the material strip a, ensuring that the material strip a always travels along the predetermined path and preventing the material strip a from deviating and causing the cutting position to deviate; the electrode dust removal module 706 is used to remove dust and debris generated during the laser cutting process, keeping the electrode surface clean and improving product quality; the main drive module 707 provides the main driving force for the conveying of material strip a; the buffer module 709 plays a buffering role during the conveying of material strip a, and can absorb or release material strip a when there is a short pause in the upstream or downstream process, ensuring the continuity of the whole machine operation.

[0026] The first roller shaft 710 is set up to guide and turn the conveying path of the material belt a, ensuring a smooth transition of the material belt a between modules and reducing frictional damage between the material belt a and the equipment.

[0027] Furthermore, a tape-connecting module 900 is provided between the adjusting roller 701 and the tension detection module 702. The tape-connecting module 900 is used to connect the end of the new tape roll to the end of the old tape when the previous tape roll a is exhausted, thereby achieving continuous production. Here, the tape-connecting module 900 is a manual tape-connecting module. In other embodiments, it can also be an automatic tape-connecting module.

[0028] In this embodiment, the adjusting roller 701, tension detection module 702, first tension roller 703, tab reinforcing rib assembly 704, first correction assembly 705, tab dust removal module 706, main drive module 707, second tension roller 708, buffer module 709 and tape connection module 900 are all existing technologies, and their structures and working principles will not be described in detail here.

[0029] like Figure 2 As shown, the auxiliary roller group includes a buffer module 709, a second correction component 801, and a dust removal component 802 arranged sequentially along the conveying direction of the material belt a. In the conveying direction of the material belt a, at least one second roller shaft 803 is arranged between any two adjacent components of the buffer module 709, the second correction component 801, and the dust removal component 802. The main roller group and the auxiliary roller group share the same buffer module 709.

[0030] If the laser-cut strip a is selected for the winding and storage path, then the buffer module 709 becomes part of the auxiliary roller group. Strip a first passes through the buffer module 709 for buffering, then undergoes further correction by the second correction component 801 to ensure accurate positioning before entering the winding roller 500. Finally, the dust removal component 802 removes any residual dust from the surface of strip a, ensuring a clean winding roll. The second roller shaft 803 guides and redirects the conveying path of strip a within the auxiliary roller group.

[0031] The main roller group and the auxiliary roller group share the same buffer module 709, which allows the material strip a to be buffered by the same buffer module 709 regardless of whether the cutting and sheet making path or the winding and storage path is selected after the laser cutting module 400. This simplifies the equipment structure and ensures the stability of the material strip a conveying in both working modes.

[0032] Thus, the electrode laser cutting and rewinding integrated machine of this embodiment, by setting up a main roller group and a secondary roller group, realizes precise control over the entire process of material strip a from unwinding to laser cutting, and then to cutting and sheet making or rewinding and storage, ensuring stable and efficient transportation of material strip a between each process, and further improving production efficiency and product quality.

[0033] like Figures 3 to 5 As shown, the electrode cutting module 600 includes a base plate 601, a traction frame 602 is provided on the base plate 601, a traction roller group 603 is provided on the traction frame 602, the material belt a passes through the traction roller group 603, and the traction roller group 603 is used to drive the material belt a; in the conveying direction of the material belt a, a belt pressing assembly 604 is provided on the upstream side of the traction frame 602, and a cutting assembly 605 is provided on the downstream side of the traction frame 602.

[0034] The traction roller assembly 603 provides driving force for conveying the strip a in the electrode cutting module 600, ensuring that the strip a can be accurately conveyed to the cutting position. The pressing assembly 604 is located upstream of the traction frame 602 and is used to press the strip a tightly before the cutting action is performed to prevent the strip a from shifting during the cutting process and to ensure cutting accuracy. The cutting assembly 605 is located downstream of the traction frame 602 and is used to cut the strip a, cutting the continuous strip a into single electrode sheets of a predetermined size.

[0035] Specifically, the pressing assembly 604 includes a support roller 6042 and a pressing block 6041 disposed on the traction frame 602. The material belt a is located between the support roller 6042 and the pressing block 6041, and the pressing block 6041 can move closer to or further away from the support roller 6042. When it is necessary to press the material belt a, the pressing block 6041 moves closer to the support roller 6042, clamping the material belt a between the support roller 6042 and the pressing block 6041; when it is necessary to release the material belt a, the pressing block 6041 moves away from the support roller 6042, and the material belt a can pass freely. In this embodiment, the pressing block 6041 is adjustablely mounted on the traction frame 602 by a cylinder. In use, the pressing block 6041 is driven to move by the cylinder.

[0036] Specifically, such as Figure 3 As shown, the cutting assembly 605 includes a pad 6051 disposed on a base plate 601, a support block 6052 disposed on the pad 6051, a cutter 6053 capable of vertical movement mounted above the support block 6052, an anvil 60521 and a dust collection box 60522 mounted on the support block 6052, the dust collection port of the dust collection box 60522 being flush with the anvil 60521, and a cutting gap 6054 between the anvil 60521 and the dust collection box 60522 to avoid the cutter 6053, the strip a being located above the anvil 60521 and the dust collection box 60522 and spanning the cutting gap 6054. When it is necessary to cut the strip a, the cutter 6053 moves downward in a vertical direction, passing through the cutting gap 6054 to cut the strip a. The anvil 60521 provides support for the cutter 6053, ensuring the cutting effect. The suction port of the dust collection box 60522 is flush with the cutting board 60521, which can promptly remove dust and debris generated during the cutting process, preventing dust from contaminating the surface of the material strip a or affecting subsequent processes. The cutting gap 6054 ensures that the cutter 6053 has sufficient room to move, while also allowing the cutting board 60521 and the dust collection box 60522 to perform their respective functions of support and dust removal.

[0037] Furthermore, such as Figure 4 , Figure 6 and Figure 7As shown, the top of the traction frame 602 is equipped with a drive mechanism 606 for driving the cutter 6053. The drive mechanism 606 includes a mounting base 6061. A follower plate 6062 is slidably mounted on the mounting base 6061 along the vertical direction via a slide rail slider assembly. A cam eccentric shaft 6063 is rotatably mounted on the mounting base 6061 via a bearing. A cam mounting plate 6064 is rotatably mounted on the cam eccentric shaft 6063 via a bearing. A follower shaft 6065 is rotatably mounted on the cam mounting plate 6064 via a bearing. The follower shaft 6065 is rotatably connected to the follower plate 6062. The cam eccentric shaft 6063 is connected to the first end of the cam mounting plate 6064, and the follower shaft 6065 is connected to the second end of the cam mounting plate 6064. A motor 6066 for driving the cam eccentric shaft 6063 to rotate is provided on the mounting base 6061. When the drive mechanism 606 is working, the motor 6066 drives the cam eccentric shaft 6063 to rotate via a synchronous belt. The cam eccentric shaft 6063 drives the cam mounting plate 6064 to swing. The cam mounting plate 6064 drives the follower plate 6062 to slide back and forth in the vertical direction via the follower shaft 6065. The follower plate 6062 then drives the cutter 6053 to move back and forth in the vertical direction, thereby cutting the material strip a. The cam mechanism has the advantages of controllable motion and low impact, which helps to ensure cutting accuracy and extend the service life of the equipment. In this embodiment, the cutter 6053 is installed at the lower end of the follower plate 6062.

[0038] like Figure 8 and Figure 9 As shown, the follower plate 6062 has a swing groove 60621 on one side facing the mounting base 6061. The cam mounting plate 6064 is located within the swing groove 60621. The width of the swing groove 60621 is D, the width of the cam mounting plate 6064 is M, and the length of the cam mounting plate 6064 is N, where M < D < N. The width D of the swing groove 60621 is greater than the width M of the cam mounting plate 6064 but less than the length N of the cam mounting plate 6064. This dimensional relationship allows the cam mounting plate 6064 to swing freely within the swing groove 60621 without jamming during the swing process. At the same time, the swing groove 60621 plays a certain limiting role in the swing amplitude of the cam mounting plate 6064, ensuring the stability and reliability of the drive mechanism 606.

[0039] like Figure 6 and Figure 7As shown, an extension rod 6067 is provided on the top of the mounting base 6061. The extension rod 6067 is located above the follower plate 6062, and the follower plate 6062 is located between the extension rod 6067 and the cutter 6053. A tension spring 6068 is provided between the extension rod 6067 and the follower plate 6062. One end of the tension spring 6068 is connected to the extension rod 6067, and the other end is connected to the follower plate 6062. The tension spring 6068 always applies an upward pulling force to the follower plate 6062. This pulling force helps the follower plate 6062 to return to its original position, and at the same time, it can eliminate the backlash in the cam mechanism transmission process, improve the transmission accuracy, and ensure that the position of the cutter 6053 is consistent each time it cuts, thereby improving the cutting quality.

[0040] like Figure 1 As shown, after the material strip a is cut, it forms an electrode sheet. The electrode sheet is conveyed to the subsequent work station by the negative pressure conveyor belt 210 and stored in the silo 220. In this embodiment, the negative pressure conveyor belt 210 and the silo 220 are both existing technologies and will not be described in detail here.

[0041] In summary, the electrode laser cutting and rewinding integrated machine provided in this embodiment integrates unwinding, laser cutting, electrode cutting, and rewinding functions, realizing the simultaneous operation of electrode rewinding and storage and electrode cutting and forming on a single machine. This eliminates the need to switch material rolls between different machines, significantly improving production efficiency and reducing production costs and equipment footprint. Furthermore, through the rational configuration of the main and auxiliary roller groups and the optimized design of the electrode cutting module 600, stable and efficient conveying and processing of the material strip a between processes is ensured, improving product quality.

[0042] 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.
