Description

Technical Field

[0001] This utility model relates to the field of composite copper foil cutting technology, specifically a cutting device for processing composite copper foil for lithium-ion batteries. Background Technology

[0002] Composite copper foil is a novel material with a "copper-polymer-copper" sandwich structure. The polymer layer is lighter, which helps to improve the energy density of the battery. However, there are still some challenges in the preparation process, equipment production speed, and yield of composite copper foil, resulting in higher manufacturing costs. In addition, issues such as material selection and the bonding force between the PP film and the metal layer also need to be further resolved.

[0003] According to application number 202020856018.2 published on the China Patent Network, this utility model discloses a copper foil cutting machine, belonging to the technical field of copper foil processing equipment. The main body of the cutting machine is rotatably connected to a feeding roller, a tension roller, and a support roller. A groove is formed on the upper surface of the main body of the cutting machine, and a slider is slidably connected within the groove. One end of the slider is fixedly connected to a crossbar, and a limit groove is formed on the surface of the crossbar. A limit block is slidably connected within the limit groove, and an adjusting sleeve is fixedly connected to the other end of the limit block. The adjusting sleeve is axially sleeved on the surface of the crossbar, and a second bearing is fixedly sleeved on the surface of the adjusting sleeve. The cutting blade of this copper foil cutting machine has a horizontal movement function. The cutting position of the cutting blade can be adjusted according to actual needs, thereby cutting copper foil of different sizes in one go, which greatly improves the cutting efficiency of the cutting machine. The adjustable seat can adjust the height of the cutting blade, which facilitates the installation of copper foil rolls and greatly improves the ease of use of the cutting machine. However, before the copper foil is transported to the cutting station, due to the extremely thin thickness of the copper foil itself, the relevant transport components of the cutting machine cannot provide sufficient support and protection, which makes the copper foil very prone to wrinkles and uneven surfaces. Even if the copper foil is leveled after cutting, a considerable proportion of the copper foil will still be skewed or not conform to the dimensions.

[0004] Therefore, the cutting machine needs to be improved to prevent the copper foil from wrinkling during the cutting process. Utility Model Content

The surface of the insert plate 17 is slidably connected to the inner wall of the connecting rod 10. A pull plate 18 is fixedly connected to the top of the push block 16.

[0019] As a technical optimization of this utility model, by setting guide strip 14, slide 15, push block 16, insert plate 17 and pull plate 18, the moving frame 12 and pressure roller 13 can be quickly disassembled and assembled, avoiding damage to the surface of pressure roller 13 after long-term use, which would prevent the composite copper foil surface from being effectively leveled.

[0020] refer to Figure 4 Two springs 19 are fixedly connected to the inner side of the push block 16, and the inner side of the springs 19 is fixedly connected to the inner wall of the slide groove 15.

[0021] As a technical optimization of this utility model, by setting the springback device 19, the push block 16 can move inward automatically, thereby improving the performance of the push block 16.

[0027] As a technical optimization of this utility model, by setting the friction pad 23, the insert plate 17 can make closer contact with the inner wall of the connecting rod 10, thereby increasing the contact area between the insert plate 17 and the connecting rod 10.

[0028] The working principle and usage process of this utility model are as follows: First, pass one end of the copper foil through the rear side of the fixing frame 3. After passing through, place it on top of the support plate 1. After placement, start the motor 5. The output end of the motor 5 drives the screw 6 to rotate. The screw 6 drives the moving block 7 to move inward through the thread. The moving block 7 drives the traction rod 8 to move inward through the rotating shaft. The traction rod 8 pushes the push plate 9 downward through the rotating shaft. The push plate 9 drives the connecting rod 10 and the limiting sleeve 11 to move downward. The limiting sleeve 11 drives the moving frame 12 and the pressure roller 13 to move downward. The roller moves downward, pressing the pressure roller 13 onto the surface of the copper foil. After pressing, the motor 5 stops and pushes the copper foil backward, allowing the pressure roller 13 to level the surface of the copper foil. Finally, if the pressure roller 13 needs to be replaced, press the pull plate 18 inward. The pull plate 18 drives the push block 16 and the insert plate 17 to move inward, moving the insert plate 17 away from the connecting rod 10. After it has moved away, start the motor 5 in reverse, causing the motor 5 to drive the connecting rod 10 upward and away from the limit sleeve 11 and the moving frame 12. After it has moved away, the user can open the moving frame 12 to replace the pressure roller 13.

[0029] In summary, this cutting equipment for processing composite copper foil for lithium-ion batteries, by setting up a moving frame 12 and a pressure roller 13, can level the surface of the copper foil, avoiding skewing and unevenness during cutting. By setting up a motor 5, screw 6, moving block 7, traction rod 8, push plate 9, connecting rod 10, and limiting sleeve 11, it can drive the moving frame 12 to move up and down, allowing the pressure roller 13 to level copper foil of different thicknesses. By setting up a guide sleeve, slide 15, push block 16, insert plate 17, and pull plate 18, it can further enhance the surface smoothing capabilities of the copper foil. The movable frame 12 and pressure roller 13 can be disassembled and replaced, avoiding damage to the surface of the pressure roller 13 during long-term use. This provides the advantage of smoothing the copper foil and solves the problem that before the copper foil is transported to the cutting station, the copper foil is extremely thin and the relevant transport components of the cutting machine cannot provide sufficient support and protection, making the copper foil prone to wrinkles and uneven surfaces. Even if the cut copper foil is leveled afterward, a considerable proportion of the copper foil will still be skewed or not conform to the dimensions.
