However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0027] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0028] like Figures 1 to 8 As shown, this utility model provides a copper foil punching and cutting integrated machine, including a frame 1. The frame 1 is provided with an unwinding mechanism 3, a pulling mechanism 4, a punching mechanism 5, a guiding mechanism 6, a cutting mechanism 7, and a collecting mechanism 8 arranged sequentially along the copper foil conveying direction. The unwinding mechanism 3 includes a receiving rack 31 for receiving the copper foil roll assembly 2 and an unwinding drive assembly for driving the copper foil roll assembly 2 to continuously unwind. The pulling mechanism 4 is used to transfer the unwound copper foil to the punching mechanism 5. The punching mechanism 5 is used to punch the copper foil transferred from the pulling mechanism 4. The guiding mechanism 6 is used to transfer the punched copper foil to the cutting mechanism 7. The cutting mechanism 7 is used to cut the punched copper foil. The collecting mechanism 8 is used to collect the cut copper foil.

[0029] In this embodiment, the copper foil roll assembly 2 is placed on the receiving rack 31, and the copper foil roll assembly 2 is continuously unwound by the unwinding drive assembly to achieve continuous feeding. The unwound copper foil is conveyed to the punching mechanism 5 by the pulling mechanism 4, and the punching mechanism 5 punches the copper foil. The punched copper foil is then conveyed to the cutting mechanism 7 by the guiding mechanism 6, and the cutting mechanism 7 cuts the punched copper foil into copper foil pieces with through holes. The cut copper foil pieces are collected by the receiving mechanism 8, realizing integrated processing of copper foil punching and cutting. This invention integrates the punching and cutting processes into a single machine, reducing the handling and transfer of copper foil between different devices during production. This enhances the practicality of the equipment, ensures standardized punching and cutting dimensions, improves punching quality and cutting efficiency, reduces the risk of work-related injuries caused by manual operation, and lowers labor intensity, thus improving production efficiency in multiple ways. Furthermore, the integrated and precise operation better guarantees processing accuracy and product quality stability. The automated feeding, conveying, and collection of copper foil through the unwinding mechanism 3, pulling mechanism 4, guiding mechanism 6, and collecting mechanism 8 reduces the time and cost of transferring materials between different devices during production, thereby increasing production efficiency and lowering labor costs.

[0030] In a preferred embodiment, the copper foil roll assembly 2 includes an air shaft 21 and a copper foil roll 22 sleeved on the air shaft 21. Bearings 23 are provided at both ends of the air shaft 21, and a transmission gear 24 is provided at one end of the air shaft 21. The bearings 23 at both ends of the air shaft 21 are supported on the receiving frame 31, and the transmission gear 24 on the air shaft 21 is connected to the unwinding drive assembly.

[0031] In this embodiment, a copper foil roll assembly 2 is formed by placing the rolled copper foil onto the air shaft 21. The copper foil roll assembly 2 can be installed on the receiving rack 31 of the unwinding mechanism 3 by the lifting trolley 9. The bearings 23 at both ends of the air shaft 21 can achieve precise positioning on the receiving rack 31. At the same time, the scale markings on the air shaft 21 can be used to determine whether the scale values ​​at the left and right ends of the copper foil roll 22 are consistent, and thus determine whether there is a deviation between the center line of the copper foil roll 22 and the center line of the equipment. After the copper foil roll assembly 2 is placed on the receiving rack 31, the transmission gear 24 on the air shaft 21 is connected to the unwinding drive assembly. The unwinding drive assembly drives the transmission gear 24 to rotate, which in turn drives the air shaft 21 to rotate, realizing the automatic unwinding of the copper foil roll 22. By controlling the rotation of the air shaft 21 through the unwinding drive assembly, the unwinding speed and tension can be controlled in real time.

[0032] It is understood that the unwinding drive component in this embodiment can be a servo motor 33, and the output end of the servo motor is equipped with a drive gear 34. The drive gear 34 meshes with the transmission gear 24 to realize that the servo motor 33 drives the air shaft 21 to rotate.

[0033] In a preferred embodiment, the receiving rack 31 is provided with a receiving groove 32 that cooperates with the bearing 23. By providing the receiving groove 32, the bearings 23 at both ends of the air shaft 21 can move within the receiving groove 32, which facilitates pushing the air shaft 21 and realizing the connection between the air shaft 21 and the unwinding drive assembly.

[0034] In a preferred embodiment, the frame 1 is provided with a limiting mechanism for restricting the movement of the bearing 23 within the receiving groove 32. The limiting mechanism includes a limiting wheel 35 and a limiting cylinder 36 for driving the limiting wheel 35 to move up and down. When the bearings 23 at both ends of the air shaft 21 are placed into the receiving groove 32, the limiting cylinder 36 drives the limiting wheel 35 to descend, thereby restricting the free movement of the bearing 23.

[0035] In a preferred embodiment, the material pulling mechanism 4 includes a first traction roller 41, a connecting platform 42, a second traction roller 43, a storage roller 44 and a third traction roller 45 arranged sequentially along the copper foil conveying direction. A lifting pressure roller 46 is provided above the connecting platform 42, and a floating component 47 is connected to the storage roller 44.

[0036] In this embodiment, the connection platform 42 and the lifting pressure roller 46 enable new rolls of material to be connected to old rolls without re-threading, reducing material changeover time. The floating component 47 drives the storage roller 44 to float up and down, compensating for tension changes in real time and providing simple and effective tension control. The floating component 47 can be a cylinder. The pulling mechanism 4 not only provides driving force to the copper foil but also ensures smoother movement of the copper foil throughout the process, preventing wrinkles or deformation and guaranteeing the quality of subsequent punching and cutting.

[0037] In a preferred embodiment, the punching mechanism 5 includes a machine base 50, a slide table 51 slidably disposed on the machine base 50, a lifting plate 52 located above the slide table 51, a punching die 53, and a punching cylinder 54. The machine base 50 is provided with a vertically arranged guide column, the lifting plate 52 is slidably engaged with the guide column, the cylinder body of the punching cylinder 54 is mounted on the lifting plate 52 and its piston rod passes through the lifting plate 52, and the punching die 53 is provided at the end of the piston rod of the punching cylinder 54.

[0038] In this embodiment, when the copper foil enters the slide table 51, the punching cylinder 54 drives the punching mold 53 to descend, and the punching mold 53 punches the copper foil. After punching is completed, the punching cylinder 54 drives the punching mold 53 to rise and reset, thereby realizing automatic punching of the copper foil and improving punching efficiency and quality.

[0039] In a preferred embodiment, the material guiding mechanism 6 includes a fourth traction roller 61, a fifth traction roller 62, and a pressing assembly arranged sequentially along the copper foil conveying direction. The pressing assembly includes an upper pressing roller 63, a lower pressing roller 64, and a pressing adjusting cylinder 65. A gap is formed between the upper pressing roller 63 and the lower pressing roller 64 for the copper foil to pass through. The pressing adjusting cylinder 65 is used to adjust the size of the gap between the upper pressing roller 63 and the lower pressing roller 64.

[0040] In this embodiment, the punched copper foil is guided into the cutting mechanism 7 by the material guiding mechanism 6, allowing for precise control of the output length. Controllable pressure is applied to the upper pressure roller 63 or the lower pressure roller 64 by the pressure regulating cylinder 65, ensuring the copper foil surface is free of indentations and that it is fed out stably and quickly. This adjusts the tension of the copper foil feed, improves cutting smoothness, and reduces wrinkles and unevenness. It is understood that the upper pressure roller 63 and the lower pressure roller 64 can be made of different materials, and electrostatic elimination can be used to avoid creases.

[0041] In a preferred embodiment, the cutting mechanism 7 includes a cutting table 71, a cutting frame 72 rotatably mounted above the cutting table 71, a cutting blade 73 mounted on the cutting frame 72, and a lifting cylinder 74 that drives the cutting frame 72 to move up and down.

[0042] In this embodiment, the cutting frame 72 is moved up and down by the lifting cylinder 74, which can cut copper foil of different thicknesses. It is highly flexible and achieves fully automated cutting through the cutting mechanism 7, thereby improving cutting accuracy.

[0043] In a preferred embodiment, the receiving mechanism 8 includes a receiving frame 81, a receiving tray 82, and a tilt adjustment cylinder 83. One end of the receiving tray 82 is rotatably connected to the receiving frame 81, the fixed end of the tilt adjustment cylinder 83 is connected to the receiving frame 81, and the piston rod end of the tilt adjustment cylinder 83 is hinged to the other end of the receiving tray 82. In this embodiment, by adjusting the tilt angle of the receiving tray 82 using the tilt adjustment cylinder 83, the required receiving tilt angle for copper foil of different sizes can be adjusted, improving the flexibility of receiving.

[0044] In a preferred embodiment, a lifting cylinder 84 is also included to drive the receiving rack 81 to move up and down. In this embodiment, the lifting cylinder 84 drives the receiving rack 81 to move up and down, flexibly adjusting the height of the receiving tray 82, ensuring that copper foils of different sizes can fall smoothly and neatly into the receiving tray 82, thus enhancing practicality.

Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
