Description

Technical Field

[0001] This invention relates to the field of copper foil production technology, and in particular to an automatic copper foil coating device. Background Technology

[0002] Copper foil is a cathodic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as a conductor. It readily adheres to insulating layers, receives printed protective layers, and, after etching, forms the circuit pattern. Copper foil production involves winding the foil into rolls, which are then often coated to prevent oxidation. Current coating processes are mostly manual, resulting in low efficiency. Machine processing, however, suffers from reduced thickness as the coating roll is used, making it impossible to automatically adjust tension during coating. This leads to poor coating quality, with messy, gap-filled surfaces and ineffective wrapping, ultimately reducing the overall coating effect.

[0003] Therefore, there is an urgent need for an automatic copper foil coating device to solve the above problems. Summary of the Invention

Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] refer to Figure 1-5 This invention provides an automatic copper foil coating device, including a support base 1, a first support frame 2 fixedly connected to the top of the support base 1, a protective cover 3 fixedly connected to the first support frame 2, a copper foil clamping assembly disposed in the middle of the protective cover 3, a copper foil roll 4 disposed on the copper foil clamping assembly, a driving assembly disposed on one side of the protective cover 3, a second support frame 5 fixedly connected to the side of the first support frame 2 away from the driving assembly, a self-adjusting laminating assembly disposed on the second support frame 5, a coating roll 36 installed in the self-adjusting laminating assembly extending into the protective cover 3, the coating roll 36 being correspondingly disposed with the copper foil roll 4, and the self-adjusting laminating assembly being drively connected to the driving assembly.

[0027] The scheme is further optimized. The self-adjusting peritoneum assembly includes a support rod 6 with one end fixedly connected to the second support frame 5. The other end of the support rod 6 extends into the protective cover 3 and is coaxially rotatably connected to a drive disk 7. The side of the drive disk 7 away from the second support frame 5 and away from the center is fixedly connected to a first support plate 8. A covering part and a tension adjustment part are provided on the first support plate 8. The covering roll 36 is installed on the covering part. The covering part is slidably connected to the first support plate 8 through the tension adjustment part.

[0028] The drive disk 7 drives the first support plate 8 to rotate, and the coating component on the first support plate 8 makes a circular motion. The copper foil roll 4 is located at the center of the circular motion, thereby realizing the winding of the coating roll 36 on the coating component onto the copper foil roll 4, and realizing the coating process of the copper foil roll 4.

[0029] In a further optimized design, a first groove 9 is provided on the first support plate 8. The coating component includes a first slider 10 slidably connected in the first groove 9. A second support plate 11 is fixedly connected to the first slider 10. A second groove 12 is provided on the second support plate 11. A second threaded rod 13 is rotatably connected in the second groove 12. A second slider 14 is threadedly connected to the second threaded rod 13. The coating roll 36 is mounted on the second slider 14 through a mounting bracket 30. The end of the second threaded rod 13 away from the first slider 10 extends out of the second support plate 11 and is connected to the drive assembly for transmission.

[0030] The length of the second groove 12 on the second support plate 11 is adapted to the overall length of the copper foil roll 4. By rotating the second threaded rod 13, the second slider 14 slides laterally in the second groove 12, thereby achieving the coating process from one end to the other of the copper foil roll 4, ensuring the completion of the coating.

[0031] The tension adjustment component further optimizes the design by including a first threaded rod 15 rotatably connected in the first slide groove 9, a first slider 10 threadedly connected to the first threaded rod 15, a first threaded rod 15 extending out of the first support plate 8 near the support rod 6 and fixedly connected to a first bevel gear 16, and a second bevel gear 17 coaxially fixedly connected to the end of the support rod 6 away from the second support frame 5, with the first bevel gear 16 and the second bevel gear 17 meshing.

[0032] The first threaded rod 15 is rotatably connected to the two walls of the first slide groove 9 through bearings at both ends. Since the first bevel gear 16 meshes with the second bevel gear 17, when the drive disk 7 drives the first support plate 8 to rotate, the first bevel gear 16 rotates along the second bevel gear 17 while driving itself to rotate. The first bevel gear 16 drives the first slider 10 to slide in the first slide groove 9. When the first slider 10 moves, it drives the coating roll 36 to move. For the use of the coating roll 36, the spacing between the coating roll 36 and the copper foil roll 4 can be adjusted according to the change of the thickness of the whole roll, so as to ensure the tension during coating and ensure the overall coating effect.

[0033] The scheme is further optimized. The drive assembly includes a drive plate 19 fixedly connected inside the protective cover 3. The drive plate 19 has a groove 20. A toothed groove is provided on one side wall of the groove 20. A first gear 18 is coaxially fixedly connected to the second threaded rod 13. The first gear 18 is located in the groove 20 and meshes with the toothed groove.

[0034] The first gear 18 meshes with the tooth groove. When the second threaded rod 13 moves in a circular motion around the copper foil roll 4, the first gear 18 rolls on the meshing tooth groove, thereby driving the rotation of the second threaded rod 13. When the second threaded rod 13 rotates, it drives the second slider 14 to move in the second slide groove 12, so that the coating roll 36 moves from one end to the other end when coating the copper foil roll 4, thus achieving coating of the entire roll.

[0035] The design was further optimized so that groove 20 is a spiral groove.

[0036] The spiral groove 20 corresponds to the operation of the tension adjustment component, thereby adapting to the movement trajectory of the tension adjustment component and ensuring that the first gear 18 is always engaged with the tooth groove in the groove 20.

[0037] The copper foil clamping assembly further optimizes the design by including a vertical plate 21 fixedly connected to the protective cover 3. Several third sliding grooves 22 are equally spaced along the circumference of the vertical plate 21. A third threaded rod 23 is rotatably connected in the third sliding groove 22. A third slider 24 is threadedly connected to the third threaded rod 23. One end of a connecting rod 25 is fixedly connected to the third slider 24. The other end of the connecting rod 25 is fixedly connected to a limiting plate 26. The limiting plate 26 is correspondingly set with the copper foil roll 4.

[0038] The copper foil roll 4 has a hollow structure in the middle. The hollow structure is inserted into the limiting plate 26. Both ends of the third threaded rod 23 are rotatably connected to the inner sidewalls of the third slide groove 22 through bearings. The rotation of the third threaded rod 23 drives the third slider 24 to slide in the third slide groove 22. When the third slider 24 moves, it causes the outer side of several limiting plates 26 to expand and abut against the inner sidewall of the hollow structure, thereby limiting and clamping the copper foil roll 4. Specifically, the limiting plate 26 is an arc-shaped structure suitable for the hollow structure, and an anti-slip rubber pad is provided between it and the hollow structure. The anti-slip rubber pad is fixedly connected to the limiting plate 26. The anti-slip rubber pad contacts the inner wall of the hollow tube structure to increase friction and ensure the stability of the limiting.

[0039] The scheme is further optimized by creating a cavity inside the vertical plate 21, in which a first motor 27 is fixedly connected. A third bevel gear 28 is fixedly connected to the output shaft of the first motor 27. One end of the third threaded rod 23 extends into the cavity and is fixedly connected to a fourth bevel gear 29. The third bevel gear 28 meshes with the fourth bevel gear 29.

[0040] The first motor 27 drives the third bevel gear 28 to rotate. When the third bevel gear 28 rotates, it drives the third threaded rod 23 to rotate synchronously through the meshing fourth bevel gear 29. Thus, the first motor 27 drives the limiting plate 26 to move, thereby achieving the clamping and limiting of the copper foil roll 4.

[0041] In a further optimized design, a drive shaft 31 is rotatably connected to the second support frame 5. One end of the drive shaft 31 extends into the protective cover 3 and is coaxially fixedly connected to a second gear 32. An annular toothed plate 33 is fixedly connected to the outer wall of the drive disc 7. The second gear 32 meshes with the annular toothed plate 33. A second motor 34 is fixedly connected to the second support frame 5. The other end of the drive shaft 31 passes through the second support frame 5 and is fixedly connected to the drive shaft of the second motor 34.

[0042] The drive shaft 31 is rotatably connected to the second support frame 5 and the side wall of the protective cover 3 via bearings. The second motor 34 drives the drive shaft 31 to rotate. When the drive shaft 31 rotates, it drives the drive disk 7 to rotate through the second gear 32 and the meshing ring tooth plate 33, thereby performing automatic film coating operation.

[0043] The design was further optimized so that the protective cover 3 has a cylindrical structure and is made of transparent glass. A door 35 is hinged on the protective cover 3.

[0044] The cylindrical structure corresponds to the circular motion during the lamination process, and the transparent glass material facilitates internal observation. The hinged door 35 facilitates the installation and removal of the copper foil roll 4 and the lamination roll 36. At the same time, after the hinged door 35 is fastened, the protective cover 3 forms a sealed state, preventing dust and other particles in the air from adsorbing onto the copper foil roll 4.
