[0022] In the description of this invention, unless otherwise explicitly defined, terms such as "set", "install", and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0023] Please refer to Figure 1 , Figure 2 and Figure 5 As shown, in one aspect, an embodiment of the present invention provides an integrated copper foil cutting and punching device for unfolding and cutting a copper foil roll 40, and punching holes in the cut copper foil, including a copper foil cutting machine 10 and a copper foil punching machine 20; the copper foil cutting machine 10 includes a first frame 14, a feeding module 11, a cutting module 12, a discharge carrier plate 13, and a loading and unloading linear module 18; the feeding module 11 is connected to the first frame 14 and is adapted to rotate and unfold the copper foil roll 40; the cutting module 12 is connected to the first frame 14 and is adapted to cut the copper foil roll 40. The unfolded copper foil; the discharge carrier plate 13 is connected to the first frame 14 and is set at the output end of the feeding module 11. The discharge carrier plate 13 is provided with vacuum suction holes 1311 suitable for adsorbing copper foil; the copper foil punching machine 20 includes a vacuum conveyor belt 28. When the cutting module 12 cuts, at least part of the copper foil is adsorbed onto the vacuum conveyor belt 28; the loading and unloading linear module 18 is adapted to drive the first frame 14 to move, so that the discharge carrier plate 13 connects to the vacuum conveyor belt 28, or so that the discharge carrier plate 13 moves away from the copper foil punching machine 20 and forms a clearance space between the two.

[0024] According to an embodiment of the present invention, the copper foil cutting and drilling integrated equipment is used to rotate and unfold the copper foil roll 40 by the feeding module 11 and lay it flat on the discharge carrier plate 13 and the vacuum conveyor belt 28. The vacuum suction hole 1311 of the discharge carrier plate 13 adsorbs the front part of the copper foil, and the top surface of the vacuum conveyor belt 28 adsorbs the rear part of the copper foil, so that the copper foil is jointly adsorbed and fixed by the vacuum conveyor belt 28 and the discharge carrier plate 13 during cutting. Then the cutting module 12 cuts the copper foil, and the cut sheet copper foil is pulled and transported by the vacuum conveyor belt 28 to the inside of the copper foil drilling machine 20 for drilling.

[0025] It should be noted that in the existing technology, if the copper foil cutting machine 10 and the copper foil punching machine 20 are fixedly connected, continuous production can be maintained. However, the operating space is small when feeding, and it is difficult for the copper foil to be aligned and pass through the slit, resulting in low material changing efficiency and easy damage to the copper foil. If the connection is canceled for the convenience of feeding, it is necessary to use handling equipment to transfer the sheet copper foil, which increases the cost and pollution risk.

[0026] According to an embodiment of the present invention, the integrated copper foil cutting and drilling equipment drives the first frame 14 to move through the loading and unloading linear module 18, so that the discharge carrier plate 13 is precisely connected to the vacuum conveyor belt 28 when the equipment is in operation, realizing continuous production of copper foil cutting and drilling; when it is necessary to replace the copper foil roll 40 or to perform initial threading (manually pulling the starting end of the new roll of copper foil onto the discharge carrier plate 13), the first frame 14 moves the discharge carrier plate 13 away from the vacuum conveyor belt 28, forming a spacious clearance space between the two, so that the operator can easily operate without having to go around or disassemble the downstream copper foil drilling machine 20, which greatly improves the cutting and drilling efficiency of copper foil.

[0027] In this embodiment, the loading and unloading linear module 18 can be a slide module, a lead screw module, a cylinder, etc.

[0028] In this embodiment, the integrated copper foil cutting and drilling equipment also includes a copper foil roll placement rack 30 for placing copper foil rolls 40 to be loaded.

[0029] In some embodiments, combined with Figure 2 As shown, the discharge carrier plate 13 is also provided with an arc-shaped relief groove 1321. The arc-shaped relief groove 1321 is located at the end of the discharge carrier plate 13 away from the feeding module 11 and on the side of the discharge carrier plate 13 away from the copper foil. The curvature of the arc-shaped relief groove 1321 is adapted to the end curvature of the vacuum conveyor belt 28.

[0030] In this embodiment, the arc-shaped clearance groove 1321 enables the top surface of the discharge carrier plate 13 to be closely connected with the top surface of the vacuum conveyor belt 28. After the copper foil extends out of the discharge carrier plate 13, it overlaps the top surface of the vacuum conveyor belt 28. Before cutting, the vacuum conveyor belt 28 adsorbs part of the copper foil, so that the copper foil is in a stable state during cutting, avoiding deviation or wrinkles and improving cutting accuracy.

[0031] In some embodiments, combined with Figure 2 and Figure 3 As shown, the copper foil cutting machine 10 also includes a stop assembly 19, which is located below the loading and unloading linear module 18. The stop assembly 19 includes a stop member 191 and a stop drive member 192. The stop member 191 is adapted to be raised and lowered under the drive of the stop drive member 192 to stop or avoid the movement of the first frame 14.

[0032] In this embodiment, after the loading and unloading linear module 18 drives the first frame 14 to move away from the vacuum conveyor belt 28 and form a clearance space, the stop drive component 192 drives the stop component 191 to rise, physically stopping the first frame 14 from below. This effectively prevents the first frame 14 from moving accidentally due to accidental equipment contact or program malfunction when workers are manually pulling copper foil, threading the conveyor belt, or changing the copper foil roll 40. After loading is completed and safety is confirmed, the stop component 191 lowers to clear the way, and the first frame 14 can then move back to the working position. This prevents safety accidents such as personnel being squeezed, pulled, or copper foil being pulled off course due to accidental activation of the loading and unloading linear module 18.

[0033] In some embodiments, combined with Figure 2 As shown, the discharge carrier plate 13 includes an adsorption plate portion 131 and a transition plate portion 132, which are located on both sides of the cutting line formed by the cutting module 12. The adsorption plate portion 131 is provided with a vacuum suction hole 1311, and the transition plate portion 132 is provided with an arc-shaped clearance groove 1321.

[0034] In this embodiment, before cutting, the adsorption plate 131 and the vacuum conveyor belt 28 jointly adsorb and fix the copper foil. After cutting, the copper foil adsorbed by the adsorption plate 131 and the copper foil adsorbed by the vacuum conveyor belt 28 are separated. The separated copper foil is transported by the vacuum conveyor belt 28 to the inside of the copper foil punching machine 20 for punching. This ensures that the copper foil at the cut position can be adsorbed and fixed by the adsorption plate 131 without shifting or curling, facilitating the next unfolding of the copper foil; while the separated copper foil can move with the vacuum conveyor belt 28 without controlling the vacuum suction hole 1311 of the adsorption plate 131 to release the adsorption, making the control logic simple and convenient.

[0035] In some embodiments, combined with Figure 2 and Figure 3 As shown, the cutting module 12 includes a laser cutting head 121 and a cutting line module 122. The laser cutting head 121 is connected to the movable end of the cutting line module 122, which extends along the axis parallel to the copper foil roll 40. The discharge carrier plate 13 is provided with a cutting clearance groove 133, which is located directly below the laser cutting head 121 along the direction perpendicular to the surface of the discharge carrier plate 13.

[0036] In this embodiment, laser cutting avoids the indentations, burrs, and deformation caused by mechanical stamping and cutting of copper foil, and is especially suitable for thin copper foil; laser cutting is a closed thermal evaporation process, which reduces the generation of metal debris and avoids copper powder contamination caused by traditional knife cutting, thus helping to maintain the cleanliness of the copper foil.

[0037] In this embodiment, the cutting linear module 122 can be a slide module, a lead screw module, a cylinder, etc.

[0038] In other embodiments, the cutting module 12 may also employ physical cutting with a cutting tool.

[0039] In some embodiments, combined with Figure 2 and Figure 3 As shown, the feeding module 11 includes a raw material roller 111, a material roller drive 112, a guide roller drive 113, and two guide rollers 114. The raw material roller 111 is adapted to mount the copper foil roll 40; the material roller drive 112 is adapted to drive the raw material roller 111 to rotate; the two guide rollers 114 are disposed between the raw material roller 111 and the discharge carrier plate 13 and their axes are parallel to the axis of the raw material roller 111. A guide gap is provided between the two guide rollers 114, which is suitable for the copper foil to pass through; the guide roller drive 113 is adapted to drive at least one of the two guide rollers 114 to rotate.

[0040] In this embodiment, in the feeding module 11, the copper foil roll 40 is mounted on the raw material roller 111, and the material roller drive 112 drives the raw material roller 111 to rotate and unwind; the unwound copper foil passes through the guide gap between the two guide rollers 114, and the guide roller drive 113 drives at least one guide roller 114 to rotate, so that the guide roller 114 actively clamps and smoothly conveys the copper foil toward the discharge carrier plate 13.

[0041] In this embodiment, the copper foil is clamped by the actively rotating guide roller 114, and the unwinding drive of the raw material roller 111 can precisely control the feeding speed and tension of the copper foil, avoiding deformation or breakage caused by passive pulling; the guide gap formed by the two guide rollers 114 can enable the copper foil to automatically center and flatten, eliminate curling stress, and effectively prevent wrinkles and deviation.

[0042] In some embodiments, combined with Figure 2 and Figure 3As shown, the raw material roller 111 includes an air expansion shaft 1111 and two mounting sleeves 1112 rotatably connected to both ends of the air expansion shaft 1111; the first frame 14 is provided with two material roller mounting grooves 141, the opening of the material roller mounting grooves 141 is located on the side of the first frame 14 away from the copper foil punching machine 20, suitable for mounting the mounting sleeves 1112; the copper foil cutting machine 10 also includes a material roller limiting assembly 15, connected to the first frame 14 and located on the side adjacent to the material roller mounting grooves 141, the material roller limiting assembly 15 includes a material roller limiting member 151 and a material roller limiting drive member 152, the material roller limiting member 151 is adapted to abut against the mounting sleeves 1112 under the drive of the material roller limiting drive member 152, and together with the groove wall of the material roller mounting groove 141, limit and fix the mounting sleeves 1112.

[0043] In this embodiment, the raw material roller 111 adopts an air expansion shaft 1111, with mounting sleeves 1112 rotatably connected to both ends. The first frame 14 is provided with two roller mounting slots 141. After the mounting sleeves 1112 are placed into the mounting slots to achieve initial positioning, the roller limiting drive 152 drives the roller limiting component 151 to move, so that it abuts against the side of the mounting sleeve 1112 and clamps and fixes the mounting sleeve 1112 together with the groove wall of the roller mounting slot 141, thereby reliably locking the raw material roller 111 in the working position. When the copper foil roll 40 needs to be replaced, the roller limiting component 151 retracts, and the raw material roller 111 can be taken out from the roller mounting slot 141.

[0044] In this embodiment, the air expansion shaft 1111 is used to facilitate the quick clamping and tightening of the core of the copper foil roll 40, while the cooperation between the mounting sleeves 1112 at both ends and the material roller mounting groove 141 enables the quick disassembly and positioning of the material roller 111. After adding the material roller limiting component 15, the limiting component and the groove wall work together to clamp the mounting sleeve 1112, effectively preventing the material roller 111 from axially moving or radially jumping during the unwinding rotation, ensuring the stability and centering accuracy of the copper foil conveying.

[0045] In some embodiments, combined with Figure 3 As shown, the material roller limiting component 151 is a first limiting roller 1511, which is rotatably connected to the movable end of the material roller limiting drive component 152. The rotation axis of the first limiting roller 1511 is parallel to the axis of the mounting sleeve 1112. When the material roller 111 is positioned, the mounting sleeve 1112 and the first limiting roller 1511 are in rolling contact rather than sliding friction, which significantly reduces wear and collision and avoids contamination of the copper foil by debris generated by friction.

[0046] In some embodiments, combined with Figure 2 and Figure 3As shown, the copper foil cutting machine 10 also includes an ion air bar 16. The ion air bar 16 is connected to the first frame 14, disposed between the feeding module 11 and the discharge carrier plate 13 and located on the side adjacent to the copper foil. The outlet of the ion air bar 16 faces the copper foil, and the axis of the ion air bar 16 is parallel to the axis of the copper foil roll 40.

[0047] In this embodiment, the ion air bar 16 can uniformly blow ion air along the entire width of the copper foil, effectively neutralizing the static electricity generated during the unwinding and guiding process of the copper foil, and preventing the adsorption of dust or debris in the air due to static electricity, thereby keeping the surface of the copper foil clean.

[0048] In some embodiments, combined with Figure 2 As shown, the copper foil cutting machine 10 also includes a dust filter 17, which is installed inside the first frame 14. It actively collects and filters trace amounts of smoke and dust, metal vapors, and fine particles that may be generated during the laser cutting process, preventing dust from accumulating inside the machine and re-adhering to the copper foil surface or contaminating precision components such as the vacuum suction hole 1311 and the ion air bar 16, thus enhancing the overall cleanliness and protection capabilities of the machine.

[0049] In some embodiments, combined with Figure 4 and Figure 5 As shown, the copper foil punching machine 20 also includes a second frame 21, a vacuum adsorption platform 22, a conveying module 27, and a punching module 24. The vacuum adsorption platform 22, the vacuum conveyor belt 28, and the punching module 24 are connected to the second frame 21. The vacuum adsorption platform 22 is located downstream of the vacuum conveyor belt 28. The conveying module 27 is connected to the vacuum conveyor belt 28 and the vacuum adsorption platform 22. The punching module 24 is located above the vacuum adsorption platform 22.

[0050] In this embodiment, after the copper foil cutting machine 10 cuts the copper foil roll into sheet copper foil, it is transported to the handling position by the vacuum conveyor belt 28. The handling module 27 transfers the copper foil from the vacuum conveyor belt 28 to the vacuum adsorption platform 22 for flattening and fixing. After the punching module 24 punches holes, the handling module 27 then transports the copper foil from the vacuum adsorption platform 22 to the downstream discharge platform 29, realizing automatic loading and unloading. This achieves continuous and automated operation of the entire process of copper foil from feeding, punching to discharge, significantly reducing the intensity of operation and improving the consistency and yield of batch processing.

[0051] In some embodiments, combined with Figure 4 and Figure 5As shown, the copper foil drilling machine 20 also includes a camera positioning module 23, which is connected to the second frame 21 and positioned above the vacuum adsorption platform 22. The camera positioning module 23 includes an X-axis positioning camera (first positioning camera 231) and a Y-axis positioning camera (second positioning camera 232). The detection field of view of the X-axis positioning camera (first positioning camera 231) and the detection field of view of the Y-axis positioning camera (second positioning camera 232) respectively cover at least part of the long side and at least part of the wide side of the copper foil. The camera positioning module 23 is communicatively connected to the drilling module 24.

[0052] In this embodiment, the copper foil is transported to the vacuum adsorption platform 22 and fixed. Then, the X-axis positioning camera 231 and the Y-axis positioning camera 232 in the camera positioning module 23 take pictures of the long side and the wide side of the copper foil, respectively. Since the camera positioning module 23 is fixed relative to the vacuum adsorption platform 22 and the drilling module 24 and the size of the copper foil is fixed (the position of the drilling position relative to the long side and the wide side is fixed), the offset size of the copper foil relative to the marked position on the vacuum adsorption platform 22 can be determined. The camera positioning module 23 sends the identified position offset data to the drilling module 24. The drilling module 24 automatically adjusts the drilling position according to the position offset data and performs a precise drilling operation on the copper foil.

[0053] By setting up an X-axis positioning camera 231 and a Y-axis positioning camera 232 that respectively cover the long and wide sides of the copper foil, the offset size of the copper foil is determined by positioning data in two directions. This replaces the traditional small-range step stitching of a single camera, solving the problem that a single camera has a small field of view and cannot locate a large area of ​​copper foil at once, significantly improving positioning efficiency and drilling accuracy. At the same time, it avoids the structural complexity and cumulative errors caused by frequent movement of the camera or copper foil, and simplifies the equipment control logic.

[0054] In this embodiment, the communication connection can be established via an intermediate controller or a programmable logic controller (PLC) for data transfer. For example, the camera positioning module 23 first sends the positioning signal (such as the acquired image) to the main control unit (such as an industrial computer or a microcontroller), and then the main control unit sends the action command to the punching module 24.

[0055] In this embodiment, the copper foil punching machine 20 includes four punching modules 24, which are arranged symmetrically around the vacuum adsorption platform 22.

[0056] In some embodiments, combined with Figures 4 to 6As shown, the drilling module 24 includes an adjustable linear module 241 and a laser drilling assembly 242. The movable end of the adjustable linear module 241 is connected to the laser drilling assembly 242, and the extension direction of the adjustable linear module 241 is parallel to the X or Y direction. It can perform micro-motion compensation in the X or Y direction based on the position deviation detected by the camera positioning module 23, thereby improving drilling accuracy; furthermore, it can move over a wide range in the X or Y direction to adapt to copper foils of different sizes.

[0057] In this embodiment, the adjustable linear module 241 can be a slide module, a lead screw module, a cylinder, etc. In some embodiments, combined with Figure 6 As shown, the drilling module 24 also includes a lifting module 243, which is adapted to drive the laser drilling assembly 242 to move up and down, thereby adjusting the Z-axis height of the laser drilling assembly 242. By driving the laser drilling assembly 242 to move up and down along the Z-axis, the distance between the laser focus and the copper foil surface can be flexibly adjusted, ensuring that the laser is always in the optimal focusing position under different thicknesses or flatness conditions, thereby improving the drilling quality and consistency.

[0058] In some embodiments, combined with Figure 6 As shown, the lifting module 243 includes a lifting mechanism 2431, a guide plate 2432, and multiple guide rods 2433. The guide plate 2432 is connected to the second frame 21. The fixed end of the lifting mechanism 2431 is connected to the guide plate 2432, and the movable end of the lifting mechanism 2431 is connected to the laser drilling assembly 242. The multiple guide rods 2433 are symmetrically arranged around the center of the lifting mechanism 2431. One end of the guide rod 2433 is fixedly connected to the laser drilling assembly 242, and the guide rod 2433 is slidably connected to the guide plate 2432.

[0059] In this embodiment, multiple guide rods 2433 are symmetrically arranged around the center of the lifting mechanism 2431 and slide in cooperation with the guide plate 2432. This provides high-precision linear guidance for the lifting movement of the laser drilling assembly 242, effectively preventing lateral offset or rotation during the lifting process and ensuring that the laser focus always maintains a stable spatial position when adjusted in the Z direction. The symmetrically arranged guide rods 2433 can evenly bear the off-center load, reducing the lateral load on the lifting mechanism 2431 (such as a cylinder or electric cylinder) and extending its service life.

[0060] In some embodiments, combined with Figure 6 As shown, the laser drilling assembly 242 includes a laser 2421, a laser connector 2422, and a galvanometer module 2423. The laser 2421 is connected to the input end of the galvanometer module 2423 through the laser connector 2422, and the output end of the galvanometer module 2423 faces the vacuum adsorption platform 22.

[0061] In this embodiment, the galvanometer module 2423 can achieve rapid scanning and drilling in a two-dimensional plane by deflecting a high-speed laser beam. It can complete the precise processing of multiple holes in its coverage area without moving the copper foil, which greatly improves the drilling efficiency on large-area copper foil. The laser 2421 is rigidly connected to the input end of the galvanometer module 2423 through the laser connector 2422, which ensures the stability and consistency of the optical path transmission and avoids beam deviation caused by vibration or displacement. Furthermore, when working in conjunction with the adjustable linear module 241 and the lifting module 243, the adjustable linear module is responsible for large-range movement and positioning, the galvanometer module 2423 is responsible for high-speed precision drilling in a small range, and the lifting module 243 adjusts the optimal focal length. The three work together to achieve drilling at any position on a large-size copper foil.

[0062] In other embodiments, the punching module 24 can also be punched by physical cutting with a tool.

[0063] In some embodiments, combined with Figure 6 As shown, the laser connector 2422 includes a connector body 24221 and a lens 24222. The connector body 24221 has a laser via and an observation hole 242211 that communicates with the laser via. The observation hole 242211 is perpendicular to the laser via. The lens 24222 is sealed to the opening of the observation hole 242211. The laser drilling assembly 242 also includes a coaxial inspection camera 2424. The inspection field of view of the coaxial inspection camera 2424 faces the observation hole 242211.

[0064] In this embodiment, the coaxial inspection camera 2424 can capture the actual transmission path of the laser beam within the laser aperture (such as the position of the light spot or scattered light) through the observation hole 242211 and the lens 24222. By analyzing the image, it can determine whether the laser beam is transmitted strictly along the preset optical axis, which can fundamentally avoid the drift of the drilling position caused by optical path deviation. There is no need to install an additional off-axis vision system, thus avoiding parallax error. At the same time, the lens 24222 seals the observation hole 242211 to prevent dust and splashes from entering the optical path, ensuring the cleanliness and long-term stability of the optical device.

[0065] In some embodiments, combined with Figure 6As shown, the copper foil drilling machine 20, which is adapted to large-area copper foil, also includes a ring-shaped fill light 25, which is coaxially arranged with the emitting end of the galvanometer module 2423. The ring-shaped fill light 25 provides uniform and shadowless coaxial illumination around the laser emission path of the galvanometer module 2423, which can significantly improve the imaging clarity and contrast of the camera positioning module 23 (X-axis positioning camera 231 and Y-axis positioning camera 232). Especially when the copper foil has high reflectivity, low texture, or ambient stray light, it can effectively suppress glare and shadow interference, thereby improving the accuracy and stability of visual recognition. At the same time, the coaxial illumination direction is consistent with the laser processing direction, which facilitates in-situ positioning confirmation before drilling, real-time monitoring during drilling, and quality inspection after drilling, without the need for additional independent lighting devices.

[0066] In some embodiments, combined with Figure 6 As shown, the copper foil drilling machine 20, which is adapted to large-area copper foil, also includes a supplementary light plate 26, which is disposed around the emitting end of the galvanometer module 2423. The illumination area of ​​the supplementary light plate 26 faces the vacuum adsorption platform 22 and covers the landing point of the laser emitted by the galvanometer module 2423. The supplementary light plate 26 is disposed around the emitting end of the galvanometer module 2423, and its illumination area directly covers the laser landing point and its surrounding area. It can provide bright, uniform and appropriately angled auxiliary illumination for the X-axis positioning camera 231 or the Y-axis positioning camera 232, significantly improving the imaging quality. In conjunction with the ring supplementary light 25, it provides illumination with a larger area and higher brightness.

[0067] In some embodiments, combined with Figure 4 and Figure 5 As shown, the conveying module 27 includes a first suction cup assembly 271, a first conveying linear module 272, a second suction cup assembly 273, and a second conveying linear module 274. The first suction cup assembly 271 is adapted to connect the vacuum conveyor belt 28 and the vacuum adsorption platform 22 under the drive of the first conveying linear module 272. The second suction cup assembly 273 is adapted to connect the vacuum adsorption platform 22 and the discharge platform 29 under the drive of the second conveying linear module 274.

[0068] In this embodiment, the first suction cup assembly 271 and the second suction cup assembly 273 can operate independently and synchronously under the drive of the first conveying linear module 272 and the second conveying linear module 274, respectively. That is, while the first suction cup assembly 271 moves the copper foil to be punched from the vacuum conveyor belt 28 into the vacuum adsorption platform 22, the second suction cup assembly 273 moves the copper foil that has been punched out from the vacuum adsorption platform 22 to the discharge platform 29, realizing parallel loading and unloading operations, greatly shortening the processing cycle of a single copper foil, and significantly improving the processing efficiency per unit time.

[0069] In this embodiment, the first linear transport module 272 and the second linear transport module 274 may be a slide module, a lead screw module, a cylinder, etc.

[0070] In some embodiments, combined with Figure 5 As shown, the copper foil punching machine 20 also includes a laser marking module 201, which is positioned above the vacuum conveyor belt 28. In some embodiments, combined with Figure 5 As shown, the copper foil drilling machine 20 also includes a positioning detection module 202, which is set above the vacuum conveyor belt 28. The positioning detection module 202 includes multiple positioning optical fibers arranged along the conveying direction of the vacuum conveyor belt 28. The positioning optical fibers are communicatively connected to the vacuum conveyor belt 28. Based on the positioning optical fibers, it is determined that the copper foil on the vacuum conveyor belt 28 has reached the handling position (the handling position is the position where the center positions of copper foils of different lengths coincide, and at this time, different specifications of copper foil correspond to different positioning optical fibers). This ensures that the center positions of copper foils of different specifications are uniform before they are handled by the vacuum conveyor belt 28, and ensures that the handling module 27 handles copper foils of different specifications from the same position, thereby reducing the control logic of the handling module 27 and reducing control costs.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
