Technical Field

[0001] This utility model relates to the field of aluminum foil processing technology, and more specifically, to an anti-deviation slitting device for processing soft-pack aluminum foil for lithium batteries. Background Technology

[0002] In the current booming development of the lithium battery industry, the processing quality of lithium battery pouch aluminum foil, as a key material, has a significant impact on the overall performance of lithium batteries. With the market's increasingly diversified requirements for lithium battery product specifications and performance, higher standards are being placed on the slitting and processing of lithium battery pouch aluminum foil. Traditional aluminum foil slitting equipment has certain limitations in design and technology, making it difficult to meet the complex and ever-changing processing needs of today.

[0003] Traditional slitting devices struggle to achieve precise control over the X and Y axes of aluminum foil cutting. Firstly, adjusting the cutting dimensions is inconvenient, making it impossible to accurately adjust cutting parameters according to the specific requirements of different products, resulting in significant dimensional deviations in the cut aluminum foil. Secondly, the lack of effective positioning and stabilization mechanisms during cutting easily leads to problems such as cutting deviation and burrs, affecting the cutting quality and surface flatness of the aluminum foil, thereby reducing the overall performance and reliability of lithium battery products. To address these issues, this device was invented. Utility Model Content

[0022] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See attached document Figure 1 This embodiment of a lithium battery soft-pack aluminum foil processing anti-deviation slitting device includes a frame 1, a receiving pad 2 fixedly installed on the top of the frame 1, the receiving pad 2 is used to receive aluminum foil and provide support for the slitting of aluminum foil, and a bracket 3 is provided on one side of the frame 1, the bracket 3 is used to wind aluminum foil.

[0024] See attached document Figure 1Each of the four corners of the frame 1 is fixedly equipped with a support rod 4. A first frame 5 is fixedly installed between two support rods 4 arranged along the width direction. A first screw 6 is rotatably installed on the first frame 5. A first moving block 7 is threadedly connected to the first screw 6, and the width of the first moving block 7 is equal to the internal width of the first frame 5, thereby limiting the movement of the first moving block 7 and allowing it to move along the first frame 5 during the rotation of the first screw 6. A frame plate 8 is fixedly installed between the two sides of the first frame 5, and the frame plate 8 is equipped with... There is a dual-axis motor 9, and supports 10 are fixedly installed on both sides of the frame plate 8. Transmission rods 11 are rotatably installed on the supports 10. The output shafts at both ends of the dual-axis motor 9 are connected to the transmission rods 11 on both sides respectively. A bevel gear set 12 is set between the transmission rod 11 and the first screw 6 on the same side. That is, when the dual-axis motor 9 is turned on, the output shafts at both ends of the dual-axis motor 9 drive the transmission rods 11 on both sides to rotate synchronously. Under the connection of the bevel gear set 12 on both sides, the first screw 6 on both sides is rotated synchronously, thereby realizing the synchronous movement of the first moving block 7 on both sides.

[0025] See attached document Figure 2 A second frame 13 is fixedly installed between two movable blocks 7 on both sides, and the second frame 13 is perpendicular to the first frame 5. A second screw 14 is rotatably installed on the second frame 13. A first stepper motor 15 is installed on the second frame 13, and the output shaft of the first stepper motor 15 is connected to the second screw 14. When in use, the first stepper motor 15 is turned on, and the output shaft of the first stepper motor 15 drives the second screw 14 to rotate. A second movable block 16 is threadedly connected to the second screw 14, and the width of the second movable block 16 is equal to the width of the inside of the second frame 13, thereby limiting the movement of the second movable block 16, so that the second movable block 16 can move along the second frame 13 during the rotation of the second screw 14. The bottom of the second moving block 16 is equipped with two cylinders 17. The piston rods of the two cylinders 17 are connected to cutters 18, and the two cutters 18 are arranged vertically to facilitate cutting aluminum foil in the X and Y directions.

[0026] See attached document Figure 3 and Figure 4A third frame 19 is fixedly installed at the middle position of the bottom of the frame 1. A double-rotating screw 20 is rotatably mounted on the third frame 19, and guide rods 21 are fixedly installed on both sides of the double-rotating screw 20 on the third frame 19. A second stepper motor 22 is set on the third frame 19, and the output shaft of the second stepper motor 22 is connected to the double-rotating screw 20. Bottom moving blocks 23 are threadedly connected to both sides of the double-rotating screw 20, and the two guide rods 21 pass through the two bottom moving blocks 23, thereby limiting the bottom moving blocks 23 and allowing the bottom moving blocks 23 on both sides to move within the double-rotating screw 20. During the rotation, the aluminum foil moves in opposite directions or away from each other. An inverted L-shaped plate 24 is fixedly installed on the top of the bottom moving block 23. A correction plate 25 is fixedly installed on the inverted L-shaped plate 24. The correction plates 25 on both sides correct the position of the aluminum foil during the opposite movement. A second cylinder 26 is set on the top of the inverted L-shaped plate 24. A pressure plate 27 is connected to the end of the piston rod of the second cylinder 26. When in use, the second cylinder 26 is turned on, and the piston rod of the second cylinder 26 drives the pressure plate 27 to move towards the aluminum foil, pressing the aluminum foil placed on the receiving pad 2, which is conducive to the smooth subsequent aluminum foil cutting.

[0027] When using this anti-deviation slitting device for processing lithium battery soft-pack aluminum foil, the aluminum foil is first wound off the support 3 and placed on the receiving pad 2 at the top of the frame 1 to prepare for subsequent processing. Then, the second stepper motor 22 is started, and its output shaft drives the double-rotating screw 20 to rotate. Under the limiting action of the guide rod 21, the bottom moving blocks 23 on both sides of the double-rotating screw 20 move in opposite directions, thereby driving the inverted L-shaped plate 24 and the correction plate 25 closer to the aluminum foil to correct its position and place it in the correct processing position. After correction, the second cylinder 26 is started, and its piston rod drives the pressure plate 27 downward to press the aluminum foil, ensuring the aluminum foil remains stable during processing and preventing deviation. Afterwards, according to... According to the required cutting size, the dual-axis motor 9 first drives the transmission rods 11 on both sides to rotate synchronously. Through the bevel gear set 12, the first screw 6 on both sides rotates synchronously, driving the first moving block 7 to move along the first frame 5, adjusting the position of the second frame 13. Then, the first stepper motor 15 is started, and its output shaft drives the second screw 14 to rotate, causing the second moving block 16 to move along the second frame 13, adjusting the position of the cutter 18. The two cutters 18 do not move at the same time, but move towards the aluminum foil at different times. The first cutter 18 moves to cut the aluminum foil once, and then the other cutter 18 moves to make a second cut. Through this sequential movement, the aluminum foil is cut into different sizes to meet the processing requirements.

[0028] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
