A copper foil die cutting efficient punching mechanism

Abstract

This invention relates to the field of die-cutting equipment technology, specifically disclosing a high-efficiency punching mechanism for copper foil die-cutting. The mechanism includes a crossbeam with a mounting base on it. Two lifting seats are symmetrically arranged above the mounting base, and a sleeve is rotatably connected to one side of each lifting seat. A peeling blade is connected between the two sleeves. This high-efficiency punching mechanism for copper foil die-cutting uses a linkage component to drive peeling blades one and two to rotate synchronously in opposite directions. This allows for rapid alternation between adhesive-laden anti-stick film and clean anti-stick film during continuous operation, eliminating the need for machine shutdown for film removal and replacement. This prevents production capacity loss and raw material waste caused by production line start-ups and shutdowns. The quick-release component allows for rapid disassembly and replacement of the peeling blade without the need for special tools, reducing manual maintenance time and costs. It also facilitates the replacement of the anti-stick film, ensuring a clean and adhesive-free peeling surface, thus eliminating the problem of residual adhesive and adhesive debris scratching the copper foil surface from the source.

Description

Technical Field

[0001] This invention relates to the field of die-cutting equipment technology, and specifically to a high-efficiency punching mechanism for copper foil die-cutting. Background Technology

[0002] Copper foil adhesive materials are widely used in high-end electronic fields such as electronic electromagnetic shielding, printed circuit boards, and conductive auxiliary materials for new energy. Their production process involves core steps such as die-cutting, waste removal, and strip separation. Currently, mainstream copper foil adhesive die-cutting equipment in the industry mostly uses metal scrapers to complete the waste removal and strip separation processes. Because the copper foil substrate surface is coated with pressure-sensitive adhesive, die-cutting is prone to problems such as adhesive overflow at the cross-section, adhesive stringing, and adhesive residue shedding. This causes residual adhesive and adhesive lumps to easily adhere to the metal scraper blade and working surface. Adhesive buildup on the scraper surface easily scratches the copper foil substrate surface, leading to product indentations, strip separation misalignment, and incomplete waste removal. Simultaneously, detached adhesive residue can cause process contamination, potentially inducing product conductivity failure and short circuits. The conventional solution is to coat the scraper surface with a low surface energy anti-stick film such as PTFE or PET, utilizing the material's hydrophobic and anti-stick properties to prevent adhesive adhesion and reduce adhesive buildup on the scraper.

[0003] Anti-stick films mostly adopt a fixed mounting structure. After long-term operation, the film will wear out, the edges will peel up, and the adhesive will become saturated and fail. The equipment needs to be shut down and production stopped. The old film needs to be removed manually and a new anti-stick film needs to be reapplied. Stopping the machine to replace the film not only reduces the die-cutting capacity and increases the labor maintenance cost, but also causes fluctuations in the start-up and shutdown conditions of the production line and the loss of raw materials.

[0004] Therefore, a high-efficiency die-cutting mechanism for copper foil is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a high-efficiency die-cutting mechanism for copper foil, which aims to solve the technical problem caused by the need to stop the machine to replace the anti-stick film.

[0006] The present invention provides a high-efficiency die-cutting mechanism for copper foil, comprising a crossbeam, a mounting base mounted on the crossbeam, and a vertical frame mounted on the frame, and further comprising: Two lifting seats are symmetrically arranged above the mounting base. Each lifting seat has a sleeve rotatably connected to one side, and a peeling knife is connected between the two sleeves. A rotating rod is coaxially mounted inside the sleeve. The diameter of the rotating rod is smaller than the inner diameter of the sleeve. A second peeling blade is connected to the rotating rod. The outer surfaces of the ends of both the second peeling blade and the first peeling blade are covered with an anti-sticking film. The length of the second peeling blade is shorter than the length of the first peeling blade. There is an angle between the first peeling blade and the second peeling blade. Quick-release components are provided between the sleeve and the first peeling blade, as well as between the rotating rod and the second peeling blade. The quick-release components are used to quickly assemble and disassemble the first peeling blade and the second peeling blade. The guide rail is installed on the top side of the upright. The length direction of the guide rail is parallel to the length direction of the frame. A slide block is slidably connected to the guide rail, and a waste material winding structure is provided on the slide block. The drive structure, mounted on the upright, is used to drive the slide to move. The linkage assembly is located between the drive structure, the rotating rod, the sleeve, and the support frame structure. The linkage assembly is used to make the rotating rod and the sleeve rotate synchronously with the movement of the slide, and to make the rotation direction of the rotating rod and the sleeve opposite.

[0007] Preferably, the drive structure includes a drive support base, a drive component, a rotating shaft, a drive gear, and a rack. The drive support base is connected to the upright frame, the drive component is mounted on the drive support base, one end of the rotating shaft is connected to the output end of the drive component, the other end of the rotating shaft is connected to the drive gear, and the rack is mounted on one side of the slide and meshes with the drive gear.

[0008] Preferably, the linkage assembly includes a transmission structure, a helical gear one, a helical gear two, and a helical gear three. The transmission structure is disposed between the rotating shaft and the rotating rod. The transmission structure is used to drive the rotating shaft and the rotating rod to rotate synchronously. The helical gear one is installed on the outer surface of the rotating rod, the helical gear two is installed on the outer surface of the sleeve, and a helical gear three meshes between the helical gear two and the helical gear one.

[0009] Its effect is that the rotating rod and the sleeve rotate synchronously in opposite directions through the helical gear set, allowing the first peeling blade and the second peeling blade to alternate, so that the clean anti-stick film can be switched without stopping the machine, thus improving the efficiency of continuous operation.

[0010] Preferably, a support plate 1 is connected to one side of the lifting seat, and a support plate 2 and a support plate 3 are fixedly connected to one side of the support plate 1. A sleeve passes through the support plate 2 and is rotatably connected to the support plate 2 through a bearing. A rotating rod passes through the support plate 3 and is rotatably connected to the support plate 3 through a bearing. A helical gear 3 is rotatably connected to the support plate 1.

[0011] Its effect is to improve the rotational stability of the sleeve and the rotating rod, prevent the peeling blade one and peeling blade two from shaking, and ensure the transmission stability between helical gear one, helical gear two and helical gear three.

[0012] Preferably, the quick-release assembly includes a connecting block, a supporting connecting plate, a positioning sleeve, and a locking structure. The connecting block is connected to the first and second peeling blades. A positioning groove is provided on one side of the connecting block, and a positioning insertion hole is provided on the inner wall of the positioning groove. The outer surfaces of the sleeve and the rotating rod are both connected to the supporting connecting plate. The supporting connecting plate is inserted into the positioning groove and is adapted to the size of the positioning groove. The positioning sleeve is inserted into the positioning insertion hole and its end is connected to the supporting connecting plate. A connecting hole is provided inside the positioning sleeve. The locking structure is connected to the positioning sleeve and is used to lock the positioning sleeve.

[0013] Its effect is that the positioning groove and positioning sleeve can be quickly aligned and positioned. With the locking structure, the disassembly and assembly of peeling blade one and peeling blade two can be completed without tools, which greatly shortens the time for changing blades and replacing anti-stick film.

[0014] Preferably, the locking structure includes a connecting sleeve, a protective sleeve, a pressing rod, a pressure plate, a spring, and a retaining ball. The connecting sleeve is inserted into the positioning sleeve. The protective sleeve is connected to the outer surface of the connecting sleeve. The positioning sleeve is located inside the protective sleeve, and the inner diameter of the positioning sleeve is adapted to that of the protective sleeve. One end of the connecting sleeve contacts the connecting block, and the other end of the connecting sleeve is connected to the mounting sleeve. One end of the positioning sleeve is located inside the mounting sleeve. The pressing rod is slidably disposed inside the connecting sleeve, passes through the end of the mounting sleeve, and is slidably connected to the mounting sleeve. The pressure plate is located inside the mounting sleeve and is slidably connected to the mounting sleeve. The pressure plate is installed on the outer surface of the pressing rod. The spring is set between the pressure plate and the protective sleeve. A part of the positioning sleeve is located inside the spring. An annular groove is opened on the outer surface of the pressing rod. Transition slopes are set between the two ends of the annular groove and the pressing rod. There are at least two fixed balls. The fixed balls are set between the annular groove and the transition slopes. At least two through holes are opened on the outer surface of the connecting sleeve. A part of the fixed ball passes through the inside of the through hole. The fixed ball and the through hole correspond one-to-one.

[0015] Its advantage lies in the fact that the locking operation of the positioning sleeve can be completed simply by pressing or releasing, making it easy to operate.

[0016] Preferably, a frame is connected to the crossbeam, and a telescopic component is installed on the frame. The output end of the telescopic component is connected to the lifting seat.

[0017] Preferably, a platform is connected to the upright frame, a sliding frame is slidably mounted on the platform, a drive support is connected to the platform, a sliding shaft is rotatably connected to one side of the sliding frame, and a tension pulley is connected to the end of the sliding shaft.

[0018] Its effect is that the movable tension pulley can adjust the tension of the synchronous belt, prevent transmission slippage, and ensure stable power transmission.

[0019] Preferably, the frame is provided with a punching unit for punching copper foil backing adhesive, and a conveying unit for conveying copper foil backing adhesive. The frame is also provided with a limiting component for limiting the copper foil backing adhesive.

[0020] The beneficial effects of this invention are: 1. By driving the first and second peeling blades to rotate synchronously in opposite directions through the linkage component, the adhesive anti-sticking film and the clean anti-sticking film can be quickly alternated while the equipment is running continuously. There is no need to stop the machine to remove and replace the film, thus eliminating the production capacity loss and raw material consumption caused by the start and stop of the production line.

[0021] 2. The quick-release assembly allows for rapid disassembly and replacement of the stripping blade without the need for special tools, reducing manual maintenance time and costs. This also facilitates the replacement of the anti-sticking film, ensuring a clean and adhesive-free stripping surface and eliminating the problem of residual adhesive and glue debris scratching the copper foil surface from the source.

[0022] 3. The drive structure moves the slide and the waste material winding structure synchronously, and the tension of the waste material is adjusted by switching the peeling knife to avoid the waste material bending and contacting the finished product, which would cause the copper foil and the adhesive to separate, thus ensuring the continuous and stable operation of the die-cutting separation process.

[0035] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0036] like Figures 1 to 11As shown, a high-efficiency die-cutting mechanism for copper foil according to the present invention includes a frame 10, on which a crossbeam 11 is provided. The length direction of the crossbeam 11 is parallel to the length direction of the frame 10. A mounting base 12 is mounted on the crossbeam 11, and the length direction of the mounting base 12 is perpendicular to the length direction of the crossbeam 11. Two lifting seats 20 are symmetrically arranged above the mounting base 12. A sleeve 21 is rotatably connected to one side of each lifting seat 20. A stripping blade 22 is connected between the two sleeves 21. A rotating rod 23 is installed inside the sleeve 21. The rotating rod 23 is coaxially arranged with the sleeve 21. The diameter of the rotating rod 23 is smaller than the inner diameter of the sleeve 21 to avoid interference between the rotating rod 23 and the sleeve 21 during rotation, ensuring smooth rotation of the rotating rod 23 and the sleeve 21. The length directions of the rotating rod 23 and the sleeve 21 are perpendicular to the length direction of the frame 10. A second peeling blade 24 is connected to the rotating rod 23. The outer surface of the ends of both the second peeling blade 24 and the first peeling blade 22 is connected to an anti-sticking film 25. The length of the second peeling blade 24 is shorter than that of the first peeling blade 22. The sleeve 21 and the first peeling blade 22 form a clearance space for the second peeling blade 24 to rotate, so as to avoid interference between the second peeling blade 24 and the first peeling blade 22 during rotation. The first peeling blade 22 and the second peeling blade 24 have an included angle. Each lifting seat 20 is fixedly installed with a support frame structure 30, which is used to support the rotating rod 23 and the sleeve 21 to ensure the stability of the rotating rod 23 and the sleeve 21 during rotation. A vertical frame 13 is installed on the frame 10, and a guide rail 14 is installed on the top side of the vertical frame 13. The length of the guide rail 14 is... The direction is parallel to the length direction of the frame 10. A slide block 15 is slidably connected to the guide rail 14. A waste material winding structure 16 is provided on the slide block 15. The waste material winding structure 16 is used to wind up waste material. A drive structure is provided on the upright frame 13. The drive structure is used to drive the slide block 15 to move so as to adjust the position of the waste material winding structure 16. A linkage component is provided between the drive structure, the rotating rod 23, the sleeve 21 and the support frame structure 30. The linkage component is used to make the rotating rod 23 and the sleeve 21 rotate synchronously with the movement of the slide block 15, and the rotation direction of the rotating rod 23 and the sleeve 21 is opposite.

[0037] During normal use, taking the anti-sticking film 25 on the peeling blade 22 in contact with the material as an example, the anti-sticking film 25 on the peeling blade 22 contacts the material and separates the waste. When adhesive accumulates on the anti-sticking film 25 of the peeling blade 22, the drive structure drives the slide 15 to move. At the same time, under the linkage of the linkage component, the rotating rod 23 and the sleeve 21 rotate simultaneously. Since the rotation direction of the rotating rod 23 and the sleeve 21 is opposite, the anti-sticking film 25 on the peeling blade 22 moves upward and the anti-sticking film 25 on the peeling blade 24 moves downward and contacts the waste. During the rotation, the movement of the slide 15 will drive the waste winding structure 16 to move, so as to ensure the tension of the waste winding structure 16 in winding the waste, so as to avoid the waste from contacting the separated copper foil adhesive product due to bending, causing the copper foil product to separate from the adhesive.

[0038] like Figure 4 The support frame structure 30 includes a support plate 31 connected to the lifting seat 20. A support plate 32 and a support plate 33 are fixedly connected to one side of the support plate 31. A sleeve 21 passes through the support plate 32 and is rotatably connected to the support plate 32 through a bearing. A rotating rod 23 passes through the support plate 33 and is rotatably connected to the support plate 33 through a bearing. The length of the rotating rod 23 is greater than the length of the support plate 33. The support plate 22 and the support plate 33 support the sleeve 21 and the rotating rod 23 respectively to ensure the stability of the sleeve 21 and the rotating rod 23 during rotation.

[0039] like Figure 2 and Figure 10 The drive structure includes a drive component support base 51 connected to the upright frame 13. A drive component 50 is fixedly installed on one side of the drive component support base 51. A rotating shaft is connected to the output end of the drive component 50. A drive gear 52 is connected to the end of the rotating shaft. A rack 53 is fixedly connected to one side of the slide block 15. The length direction of the rack 53 is parallel to the length direction of the frame 10. The rack 53 is meshed with the drive gear 52.

[0040] During the alternating use of peeling blade 22 and peeling blade 24, the drive unit 50 drives the rotating shaft and drive gear 52 to rotate. At this time, the drive gear 52 will drive the slide 15 to move along the length of the guide rail 14, and the waste material winding structure 16 moves synchronously with the slide 15, thereby realizing the position adjustment of the waste material winding structure 16.

[0041] like Figure 2 , Figure 4 and Figure 11The linkage component includes a transmission structure 54 disposed between the rotating shaft and the rotating rod 23. The transmission structure 54 is used to drive the rotating shaft and the rotating rod 23 to rotate synchronously. The transmission structure 54 is a synchronous belt and pulley transmission structure. Since it is an existing mature technology, it is not described in detail. The outer surface of the rotating rod 23 is connected to a helical gear 55, and the outer surface of the sleeve 21 is connected to a helical gear 56. A helical gear 57 is meshed between the helical gear 55 and the helical gear 56. The helical gear 57 is rotatably connected to the support plate 31. The support plate 31 provides stable support for the rotation of the helical gear 57. Through the setting of the linkage component, the stripping blade 22 and the stripping blade 24 are used alternately while the waste winding structure moves.

[0042] As the shaft rotates, the power transmission through the transmission structure 54 causes the rotating rod 23 to rotate. At the same time, the first helical gear 55 rotates simultaneously. Under the meshing transmission of the third helical gear 57, the second helical gear 56 will drive the sleeve 21 to rotate in the opposite direction. Taking the first peeling blade 22 in contact with the copper foil in the initial state as an example, the first peeling blade 22 rotates upward and the second peeling blade 24 rotates downward, so that the anti-stick film 25 in contact with the second peeling blade 24 moves downward and comes into contact with the copper foil product, thereby ensuring that the conveying process is uninterrupted and the copper foil is continuously processed.

[0043] It should be noted that a protective box is connected to the support plate 31, and helical gears 55, 56, and 57 are all located inside the protective box. The rotating rod 23 and the sleeve 21 both pass through the protective box and are rotatably connected to it. To more clearly illustrate the composition of the linkage components, the specific structure of the protective box is not shown in the figure.

[0044] like Figures 2 to 9Quick-release assemblies are provided between the sleeve 21 and the first peeling blade 22, and between the rotating rod 23 and the second peeling blade 24. These quick-release assemblies enable rapid assembly and disassembly of the first peeling blade 22 and the second peeling blade 24. Each quick-release assembly includes a connecting block 40 connected to one side of the first peeling blade 22 and the second peeling blade 24. A positioning groove 401 is provided on one side of the connecting block 40, and a positioning insertion hole 402 is provided on the inner wall of the positioning groove 401. Support connecting plates 41 are connected to the outer surfaces of both the sleeve 21 and the rotating rod 23. The support connecting plates 41 are inserted into the positioning groove 401 and are adapted to the size of the positioning groove 401. A positioning sleeve 42 is connected to the support connecting plate 41. The positioning sleeve 42 is inserted into the positioning hole 402. The outer diameter of the positioning sleeve 42 is adapted to the inner diameter of the positioning hole 402. The positioning sleeve 42 is provided with a connecting hole 421. The connecting hole 421 is divided into a lower section and an inclined section. The diameter of the lower section is larger than the inner diameter of the positioning sleeve 42. The diameter of the lower section is connected to the large diameter of the inclined section and is adapted to the large diameter of the inclined section. The small diameter of the inclined section is the same as the inner diameter of the positioning sleeve 42 and is connected to it. The positioning sleeve 42 is connected with a locking structure. The locking structure is used to lock the positioning sleeve 42 to connect the support connecting plate 41 and the connecting block 40.

[0045] The locking structure includes a connecting sleeve 43 inserted into the positioning sleeve 42, a protective sleeve 44 connected to the outer surface of the connecting sleeve 43, the positioning sleeve 42 located inside the protective sleeve 44, the inner diameter of the positioning sleeve 42 and the protective sleeve 44 being compatible, and one end of the connecting sleeve 43 contacting the connecting block 40, the other end of the connecting sleeve 43 connected to the mounting sleeve 45, a portion of the positioning sleeve 42 located inside the mounting sleeve 45, and the outer diameter of the positioning sleeve 42 being smaller than the inner diameter of the mounting sleeve 45, the positioning sleeve 42 and the mounting sleeve 45 being coaxially arranged, a pressing rod 46 slidably arranged inside the positioning sleeve 42, the pressing rod 46 passing through the end of the mounting sleeve 45 and slidably connected to the mounting sleeve 45, a pressure plate 47 fixedly connected to the outer surface of the pressing rod 46, the pressure plate 47 located inside the mounting sleeve 45 and slidably connected to the mounting sleeve 45, the pressure plate 47 and the mounting sleeve 45 being ... A spring 48 is provided between the ends of the protective sleeve 44. A part of the positioning sleeve 42 is located inside the spring 48. An annular groove 461 is provided on the outer surface of the pressing rod 46. Transition slopes are provided between the two ends of the annular groove 461 and the pressing rod 46. At least two fixing balls 49 are provided between the annular groove 461 and the transition slopes. At least two through holes are provided on the outer surface of the connecting sleeve 43. A part of the fixing ball 49 passes through the inside of the through hole. The fixing ball 49 corresponds to the through hole one by one. The diameter of the fixing ball 49 is larger than the diameter of the through hole to prevent the fixing ball 49 from separating from the inside of the through hole. The through hole is designed to taper from the inner wall of the connecting sleeve 43 to the outside so that the fixing ball 49 can be reset and enter the inside of the annular groove 461. The fixing ball 49 is fixed by cooperating with the inclined section of the connecting hole 421.

[0046] When installing peeling blade 22 and peeling blade 24, first engage the positioning groove 401 of the connecting block 40 with the support connecting plate 41. At this time, the positioning sleeve 42 is inserted into the positioning hole 402. Then, press down the pressing rod 46 to allow the fixing ball 49 to enter the annular groove 461. At this time, all the fixing balls 49 are located inside the connecting sleeve 43. During the pressing of the pressing rod 46, the pressure plate 47 will squeeze the spring 48. At this time, the spring 48 is in a compressed state. Then, insert the connecting sleeve 43 into the positioning sleeve 42. The fixed ball 49 corresponds to the inclined section of the connecting hole 421. Then, the pressing rod 46 is released. Under the reaction force of the spring 48, the pressing rod 46 will return to its original position. At this time, the transition slope at the bottom of the annular groove 461 will squeeze the fixed ball 49, causing a part of the fixed ball 49 to pass through the inside of the through hole and fit against the inner wall of the inclined section of the connecting hole 421. At this time, the pressing rod 46 will not move under the action of no external force, thus making the fixed ball 49 fit tightly against the inner wall of the inclined section of the connecting hole 421, thereby connecting the positioning sleeve 42 and the connecting sleeve 43. After the connecting sleeve 43 is fixed, the protective sleeve 44 is fitted onto the outer surface of the positioning sleeve 42, and the end of the protective sleeve 44 is tightly fitted against one side of the connecting block 40. Since the position of the positioning sleeve 42 is fixed, the position of the protective sleeve 44 is also fixed. At this time, the supporting connecting plate 41 and the connecting block 40 are connected together, completing the installation of the first peeling blade 22 and the second peeling blade 24. When it is necessary to remove the first peeling blade 22 or the second peeling blade 24, simply press the pressing rod 46. At this time, under the action of the perforation, the fixing ball 49 enters the annular groove. Inside 461, the positioning sleeve 42 and the protective sleeve 44 are no longer connected. Then, the installation sleeve 45 is moved upward to separate the connecting sleeve 43 from the positioning sleeve 42. Then, the peeling knife 1 22 or peeling knife 24 can be removed to separate the connecting block 40 from the support connecting plate 41. This makes the operation of peeling knife 1 22 and peeling knife 24 easier. After peeling knife 1 22 and peeling knife 24 are used alternately, peeling knife 1 22 and peeling knife 24 can be quickly removed, which makes it convenient to replace the anti-stick film 25 connected to peeling knife 1 22 and peeling knife 24.

[0047] like Figure 10 and Figure 11A platform 17 is connected to the upright frame 13. A sliding frame 18 is slidably mounted on the platform 17. A drive support 51 is connected to the platform 17. A sliding shaft 19 is rotatably connected to one side of the sliding frame 18. A tension pulley 110 is connected to the end of the sliding shaft 19. The tension pulley 110 is connected to the synchronous belt of the transmission structure. A displacement component 111 is provided on the platform 17. The displacement component 111 is connected to the sliding frame 18 and is used to drive the sliding frame 18 to move. A telescopic component 112 is installed on the frame 10. The output end of the telescopic component 112 is connected to the lifting seat 20. The displacement component 111 is either a linear module or a telescopic component. The telescopic component and the telescopic component 112 include, but are not limited to, electric push rods, cylinders, etc.

[0048] The displacement component 111 drives the sliding frame 18 to move along the platform 17, and the tension pulley 110 moves accordingly, tightening the synchronous belt of the transmission structure 54, adjusting the tension of the synchronous belt, preventing the synchronous belt from loosening and slipping, and ensuring the power transmission accuracy between the rotating shaft and the rotating rod 23.

[0049] like Figure 1 The frame 10 is equipped with a punching unit 60, which is used to punch the copper foil backing adhesive. The frame 10 is also equipped with a conveying unit 61, which is used to convey the copper foil backing adhesive to ensure the normal operation of the punching process. Along the conveying direction of the conveying unit 61, the mounting base 12 and the lifting base 20 are located behind the punching unit 60. The frame 10 is equipped with a limiting component 62, which is used to limit the copper foil backing adhesive to prevent the copper foil backing adhesive from shifting position, so that the punching unit 60 can punch the copper foil backing adhesive better. The punching unit 60, the conveying unit 61 and the limiting component 62 are all existing mature technologies, so their specific structures and working principles are not described.
