Technical Field

[0001] This utility model is a laser punching tab cutting knife, belonging to the technical field of die-cutting equipment. Background Technology

[0002] Battery tabs are crucial components connecting the internal electrode materials of a battery to the external circuitry, serving to conduct current and establish a connection. The manufacturing quality of battery tabs directly affects key performance characteristics such as internal resistance, capacity utilization, and cycle life. Currently, battery tabs are primarily manufactured through mechanical punching or pure laser cutting. However, mechanical punching exacerbates mold wear, leading to frequent mold changes and downtime, and results in a high rate of burr defects. Pure laser cutting can cause heat-affected zones, leading to coating peeling, and also results in low processing speed and high energy costs.

[0003] Patent No. CN222536619U discloses a laser die-cutting device for battery tabs. By incorporating a structure including an air duct, dust extraction head, material feeding chute, opening slot, debris drawer, fan, connecting pipe, connector, and dustproof net, it can absorb and collect debris generated during the laser die-cutting process, preventing debris from adhering to the electrode sheet and affecting subsequent tab die-cutting, thereby improving the product quality of the tabs. The device also features a limiting component that allows for easy removal of the entire debris drawer, facilitating cleaning of the debris inside and improving practicality. However, the limiting procedure for the debris drawer is cumbersome and not quick enough. Furthermore, the laser cutting process can cause the electrode coating to peel off. Therefore, there is an urgent need for a laser-cutting tab cutting tool to address these issues. Utility Model Content

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figures 1-7 This utility model provides a technical solution: a laser-cutting electrode tab cutter, comprising a laser die-cutting machine 1, a base plate 6, a through-hole rectangular shell 7, a positioning rod 11, and an adjusting block 27. The laser die-cutting machine 1 has a slot 15 on its front side, a guide chute 13 communicating with the slot 15 on its upper side, a cylinder 9 installed in the middle of the upper part of the base plate 6, a through-hole rectangular strip 14 slidably installed inside the through-hole rectangular shell 7, a lockable universal wheel 8 installed below the through-hole rectangular shell 7, a threaded rear end of the positioning rod 11 with a nut 25 threaded to the outer side of the thread, and a corresponding adjustment block 27 on the right side of the laser die-cutting machine 1. The square groove 26 is connected to the groove 15. A square rod 22 is slidably connected inside the square groove 26. A roller 23 is installed at the left end of the square rod 22. A pull plate 10 is fixed to the right end of the square rod 22. A second spring 21 is installed on the left side of the pull plate 10. The second spring 21 is sleeved on the outside of the square rod 22. The second spring 21 is connected to the right side of the laser die-cutting machine 1. A laser cutting head 28 is installed below the adjusting block 27. This design solves the problem that the original device's limiting steps for the debris drawer are cumbersome and not fast enough. Moreover, the processing method is laser cutting, which can cause the electrode coating to peel off.

[0024] As the first embodiment of this utility model: A rectangular plate 24 is installed inside the slot 15. A cylinder 18 is slidably installed through the middle of the rectangular plate 24. A circular piece 16 is fixed to the left end of the cylinder 18. A first spring 17 is sleeved on the outside of the cylinder 18. The left end of the first spring 17 is fixed to the circular piece 16, and the right end of the first spring 17 is connected to the rectangular plate 24. Through the cooperation of the cylinder 18, the circular piece 16, the rectangular plate 24, and the first spring 17, it is convenient to push out the debris drawer 5. A guide groove 19 is provided on the front side of the cylinder 18. A positioning groove 20 is provided on the left end of the guide groove 19. The debris drawer 5 is slidably inserted into the slot 15. A handle is provided on the front side of the debris drawer 5. The debris drawer 5 is convenient for receiving debris. The guide groove 19 is convenient for providing rolling space for the roller 23. The positioning groove 20 is convenient for the square rod 22 to be inserted, thereby limiting the cylinder 18. The laser die-cutting machine 1 has fixed bases 2 installed at its left and right ends. Two transmission rollers 3 are rotatably installed inside each fixed base 2. The multiple transmission rollers 3 facilitate the guidance of the electrode sheets. Multiple through-hole rectangular shells 7 are provided, and two positioning rods 11 are provided. The base plate 6 is installed in the middle of the multiple through-hole rectangular shells 7. The two positioning rods 11 facilitate the limiting of the multiple through-hole rectangular strips 14. An L-shaped plate 4 is installed at the front end of the laser die-cutting machine 1. Multiple fans 12 are installed on the rear side of the vertical end of the L-shaped plate 4. These fans blow the cut debris into the guide chute 13, preventing it from adhering to the electrode. An adjusting cylinder 29 is installed at the front end of the adjusting block 27. The telescopic shaft of the adjusting cylinder 29 passes through the adjusting block 27, and a cutting blade 30 is installed at the end of the telescopic shaft. The cutting blade 30 is a composite material of shape memory alloy and piezoelectric ceramic, with a gradient composite coating on its surface. Through the cooperation of the cutting blade 30 and the adjusting cylinder 29, the contour cut by the laser cutting head 28 can be refined. The cutting blade 30, made of a shape memory alloy and piezoelectric ceramic composite material, allows for adjustment of the cutting edge gap.

[0025] As a second embodiment of this utility model: the adjusting block 27 is installed on the linear drive mechanism of the laser die-cutting machine 1 to realize the lateral movement of the adjusting block 27. In use, first move the device to a suitable position, then lock the multiple locking universal wheels 8, then connect the device to an external power source, then unscrew the nuts 25 at the rear ends of the two positioning rods 11, then pull out the two positioning rods 11, then start the cylinder 9 to lift the laser die-cutting machine 1, thereby causing the multiple through-hole rectangular strips 14 to move upward. When the laser die-cutting machine 1 moves to a suitable height, reset the two positioning rods 11, pass through the multiple through-hole rectangular strips 14, and tighten the two nuts 25, then reset the extension end of the cylinder 9, so that the laser die-cutting machine 1 is fixed at the ideal working height. Then, pass the electrode sheet through the two ends of the transmission rollers 3 and connect it to the external transmission device, then start the laser cutting head 28 to perform contour cutting on the electrode sheet, then power on the cutting blade 30, and then adjust the cutting speed of the cutting blade 30 according to the thickness of the material. To improve precision, the electrode sheet undergoes secondary finishing. Simultaneously, multiple fans 12 are activated to blow away debris. The debris slides down the guide chute 13 into the debris drawer 5 within the slot 15. When the debris accumulates to a certain level, the pull plate 10 is pulled, causing the square rod 22 to slide along the square groove 26. At this time, the second spring 21 is stretched, and the roller 23 disengages from the positioning groove 20. Then, under the reset action of the first spring 17, the circular piece 16 pushes out the debris drawer 5. Finally, the pull plate 10 is released, and under the reset action of the second spring 21, the roller... Roller 23 rests against the guide groove 19, making it easier for personnel to pull out the debris drawer 5. After the debris is cleaned up, the debris drawer 5 is inserted into the slot 15. At this time, the debris drawer 5 abuts against the disc 16, causing the cylinder 18 to slide. The first spring 17 is compressed, and the roller 23 rolls in the guide groove 19. When the roller 23 is aligned with the positioning groove 20, the second spring 21 returns to its original position because the roller 23 loses the resistance from the inner wall of the guide groove 19, causing the roller 23 to re-insert into the positioning groove 20, thus achieving the positioning of the debris drawer 5.
