Description

Technical Field

[0001] This utility model belongs to the field of soft copper busbar production technology, specifically relating to a soft copper busbar cutting and blanking device. Background Technology

[0002] Soft copper busbars are an important material used in power transmission and electronic equipment manufacturing. They are usually formed by stacking multiple layers of copper foil or copper busbars. They have good conductivity and flexibility, which can adapt to the bending requirements of complex installation spaces and ensure the stability of current transmission. They are widely used in electrical equipment, electronic products and communication fields.

[0003] In the production of soft copper busbars, cutting and blanking is a fundamental process that determines the quality of subsequent processing. The substrate, which is in the form of strips or sheets, must first be cut to a preset size, and then stacked, bent, and welded to form the final product.

[0004] However, existing cutting devices mostly adopt a single-blade reciprocating cutting structure, which has certain limitations in its working mode: a single cutting operation requires the completion of a full "cutting-resetting" cycle before the next operation can begin. This intermittent operation directly limits the effective number of cutting operations per unit time, resulting in low overall production efficiency and making it difficult to meet the needs of mass production of soft copper busbars.

[0046] The following will be combined with the appendix Figures 1-9 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0047] Please see Figures 1-9The soft copper busbar cutting and feeding device 100 of this utility model embodiment includes a frame 10, a cutting component 20 and a coating component 30. The cutting component 20 and the coating component 30 are both disposed on the frame 10. A feeding rack 40 is disposed at one end of the frame 10 and a material rack component 50 is disposed on one side of the frame 10. The cutting component 20 includes a first mounting base 21, a first roller 22 and a plurality of blades 23. The first mounting base 21 is disposed on the frame 10. The first roller 22 is rotatably disposed on the first mounting base 21. The plurality of blades 23 are disposed on the outer peripheral surface of the first roller 22 and are spaced apart circumferentially along the outer peripheral surface of the first roller 22.

[0048] Compared with the prior art, the soft copper busbar cutting and blanking device 100 of this utility model uses a frame 10, a cutting component 20, and a coating component 30 in cooperation. Both the cutting component 20 and the coating component 30 are mounted on the frame 10. The coating component 30 is used to coat the bottom of the sheet or strip substrate before cutting, effectively forming a physical isolation layer to prevent wear or contamination of the bottom of the substrate during transport, ensuring the flatness and cleanliness of the substrate surface. Simultaneously, it assists in the transport of the cut copper foil or copper busbar. The cutting component 20 includes a first mounting base 21, a first roller 22, and multiple blades 23. By circumferentially arranging multiple blades 23 on the outer circumferential surface of the first roller 22, the continuous rotation of the first roller 22 enables continuous cutting of the substrate by the blades 23, effectively increasing the effective cutting times per unit time, adapting to the needs of batch production of soft copper busbars, and improving production efficiency.

[0049] In some embodiments, each blade 23 protrudes from the outer circumferential surface of the first roller 22. Both ends of the first roller 22 are provided with shoulder areas 221. The blade edge of each blade 23 forms a height difference H with the shoulder area 221, where the height difference H satisfies the formula: 0.01mm ≤ H ≤ 0.15mm. The height difference H cannot be too large or too small. When the height difference H is too small (H < 0.01mm), the blade edge of the blade 23 protrudes insufficiently from the shoulder area 221, and the blade 23 cannot completely cut the substrate. This results in some material remaining connected at the cut, requiring secondary cutting or manual processing. This not only reduces production efficiency but also causes tearing and increased burrs due to secondary stress. Furthermore, incomplete cutting causes continuous friction between the blade 23 and the uncut substrate, rather than instantaneous cutting, leading to rapid dulling of the blade edge, shortening its service life, and increasing equipment maintenance costs. When the height difference H is too large, i.e. H > 0.15 mm, the blade edge of the blade 23 protrudes too much from the shoulder area 221. The soft copper busbar material is soft and highly ductile. Excessive protrusion will cause the blade 23 to excessively compress the substrate when cutting, resulting in severe burrs, tears, or warping at the cut edge. At the same time, the excessive height difference will cause the blade 23 to bear greater shear stress during cutting. Especially when it contacts the third roller shaft 26 or the support structure, it may cause rigid collision due to improper control of the gap 28, resulting in blade edge breakage and wear of the third roller shaft 26.

[0050] Therefore, the height difference H is set to satisfy the relationship: 0.01mm≤H≤0.15mm, which effectively ensures that the blade 23 has sufficient protrusion to completely cut the substrate in one go, while avoiding excessive compression of the substrate when the blade 23 cuts in.

[0051] Furthermore, the height difference H can be 0.01mm, 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.06mm, 0.07mm, 0.08mm, 0.09mm, 0.1mm, 0.11mm, 0.12mm, 0.13mm, 0.14mm, or 0.15mm. However, it is not limited to the listed values; other values ​​within the range are also applicable.

[0052] In some embodiments, the cutting assembly 20 further includes a first drive member 24, a second roller 25, and a third roller 26. The second roller 25 and the third roller 26 are rotatably mounted on the first mounting base 21. The second roller 25, the first roller 22, and the third roller 26 are sequentially mounted on the first mounting base 21 from top to bottom. The output shaft of the first drive member 24 is connected to either the first roller 22 or the third roller 26. Both the first roller 22 and the third roller 26 are provided with gears 27. The gears 27 of the first roller 22 and the third roller 26 mesh. A gap 28 is provided between the shoulder area 221 of the first roller 22 and the third roller 26.

[0053] Through the coordinated use of the first driving component 24, the second roller 25, and the third roller 26, which are sequentially arranged from top to bottom on the first mounting base 21, a three-layer clamping structure of "upper pressure-middle cutting-lower support" is formed for sheet or strip substrates. During transport, the substrate is tightly confined between the rollers, effectively suppressing warping and offset caused by the flexibility of the soft copper busbar, ensuring that the blade 23 accurately acts on the preset cutting trajectory, significantly reducing dimensional deviations, and guaranteeing consistency in batch cutting. The first driving component 24 drives the first roller 22 or the third roller 26 to rotate. The first roller 22 and the third roller 26 rotate synchronously through gear 27 meshing. This synchronicity avoids cutting lag or lead caused by differences in roller speed, enabling the substrate to be stably and continuously cut during continuous transport. A gap 28 is provided between the shoulder area 221 of the first roller 22 and the third roller 26, which provides passage space for the substrate and the bottom film, to ensure that the blade 23 cuts the substrate.

[0054] In some embodiments, the width L of the gap 28 satisfies the relationship: H < L ≤ a + n, and 0 ≤ n ≤ b, where a is the thickness of the foil and b is the thickness of the base film. By setting the width L of the gap 28 to be greater than H, it is effectively ensured that the width L of the gap 28 is greater than the protrusion of the blade 23. This means that when the blade 23 rotates with the first roller shaft 22, it will not directly contact the third roller shaft 26 even at the moment of cutting, fundamentally avoiding rigid collision between the blade and the roller shaft, and effectively preventing the blade 23 from breaking and the surface of the third roller shaft 26 from wearing. Setting L ≤ a + n makes the width of the gap 28 match the total thickness of the substrate and the base film. When 0 ≤ n ≤ b, it is ensured that the gap 28 is slightly larger than the thickness of the foil, but does not exceed the total thickness of the substrate and the base film. This adaptability can provide sufficient passage space for the substrate and avoid compression deformation caused by the gap 28 being too small. By controlling the width of the gap 28, the substrate is kept in a stable clamped state without being excessively squeezed during cutting. For soft and highly ductile substrates, this avoids localized wrinkles in the substrate during cutting due to excessively small gaps 28, or shaking of the substrate when the blade 23 cuts in due to excessively large gaps 28.

[0055] In some embodiments, the coating assembly 30 includes a second mounting base 31, a guide shaft 32, a fourth roller shaft 33, and a fifth roller shaft 34. The second mounting base 31 is disposed on the frame 10. The guide shaft 32, the fourth roller shaft 33, and the fifth roller shaft 34 are rotatably disposed on the second mounting base 31. The fourth roller shaft 33 is located above the fifth roller shaft 34. Four guide shafts 32 are provided, and the four guide shafts 32 are rectangularly disposed on the second mounting base 31.

[0056] The second mounting base 31, guide shaft 32, fourth roller shaft 33, and fifth roller shaft 34 work together. Four guide shafts 32 are arranged in a rectangular shape on the second mounting base 31, effectively limiting and guiding the base film and substrate, assisting in the lamination of the base film and substrate. By positioning the fourth roller shaft 33 above the fifth roller shaft 34, an upper-supporting and lower-pressing roller structure is effectively formed. When the substrate and base film enter between the two rollers simultaneously, the clamping force of the upper and lower rollers tightly adheres the base film to the bottom of the substrate, eliminating problems such as air bubbles and loose adhesion, ensuring the bonding strength between the base film and the substrate. For flexible substrates such as soft copper busbars, this pressing method avoids substrate deformation caused by excessive localized force, while protecting the base film from damage, balancing the lamination effect and the integrity of the substrate. Meanwhile, the rectangular layout of the guide shaft 32, together with the pressing structure of the fourth roller shaft 33 and the fifth roller shaft 34, forms a continuous coating process. The substrate and the base film are simultaneously pressed into the rollers by the limiting and guiding of the guide shaft 32, which can precisely match the continuous conveying rhythm of the cutting assembly 20. This synergy avoids misalignment, stretching, or tearing caused by inconsistent conveying speeds of the coating and the substrate, ensuring the continuity of coating and cutting, and improving overall production efficiency.

[0057] In some embodiments, two coating components 30 are provided, and the cutting component 20 is disposed between the two coating components 30. With the two coating components 30, the coating component 30 located in front of the cutting component 20 can coat the bottom of the substrate before cutting, preventing scratches and contamination of the substrate during transport to the cutting component 20, and also assisting in the cutting of the substrate. The coating component 30 located behind the cutting component 20 can shape the edges of the cut substrate. The edges of the cut substrate may have residual burrs or protrusions, which can easily scratch other materials or affect the welding adhesion in subsequent processes. The fourth roller 33 and the fifth roller 34 of the coating component 30 can act as shaping rollers, pressing the cut edges with appropriate pressure to flatten or adhere the burrs to the substrate surface, replacing a separate deburring process, simplifying the process while improving cut regularity.

[0058] In some embodiments, of the two coating assemblies 30, the coating assembly 30 located at the other end of the frame 10 is provided with a guide plate 35, and the other end of the frame 10 is provided with a conveyor belt 60, with the guide plate 35 located above the conveyor belt 60. Through the combined use of the guide plate 35 and the conveyor belt 60, the bottom surface and substrate before cutting are both continuous rolls, while the substrate after cutting consists of multiple independent sheet substrates. The guide plate 35, through the physical separation of edges or inclined surfaces, allows the sheet substrates to slide down the guide plate 35 to the conveyor belt 60 due to their own weight, while the continuous bottom film is guided to another path (such as the second take-up shaft 123), effectively separating the two. This not only provides a clean material base for subsequent stacking, welding and other processes, but also enables the orderly recycling of the bottom film, facilitating its reuse and avoiding tearing, tangling or waste caused by disorderly stacking, thereby reducing the cost of bottom film consumables.

[0059] In some embodiments, the material rack assembly 50 includes a support 51, a first feeding section 52, and a first receiving section 53. The support 51 is disposed on one side of the frame 10, extending from one end of the frame 10 to the other end. The first feeding section 52 and the first receiving section 53 are sequentially spaced on the support 51. Through the cooperative use of the support 51, the first feeding section 52, and the first receiving section 53, the sequentially arranged first feeding section 52 and first receiving section 53, along with the laminating assembly 30, the cutting assembly 20, etc., form a linear process of "feeding, conveying, processing, and receiving". After the substrate is output from the first feeding section 52, it passes through the laminating assembly 30 and the cutting assembly 20. The waste portion of the substrate is recycled by the first receiving section 53, avoiding twists, entanglements, or deviations in the substrate conveying path caused by a messy layout, ensuring a smooth and continuous process that adapts to continuous production rhythms.

[0060] Further, the first feeding part 52 includes a first sliding seat 521 and a first feeding shaft 522. The first sliding seat 521 is slidably disposed on the bracket 51, and the first feeding shaft 522 is rotatably disposed on the first sliding seat 521. The first feeding shaft 522 is located above the feeding rack 40. The first receiving part 53 includes a second driving member 531, a second sliding seat 532 and a first receiving shaft 533. The second sliding seat 532 is slidably disposed on the bracket 51, and the first receiving shaft 533 is rotatably disposed on the second sliding seat 532. The first receiving shaft 533 is located above the cutting assembly 20, and the output shaft of the second driving member 531 is connected to the first receiving shaft 533.

[0061] Through the cooperative use of the first sliding seat 521 and the first feeding shaft 522, the first sliding seat 521 can slide along the bracket 51, and the position of the first feeding shaft 522 (along one end of the frame 10 to the other end) can be flexibly adjusted according to the width of the substrate and the position of the feeding rack 40. This ensures that the substrate is aligned with the coating assembly 30 after being output from the first feeding shaft 522, avoiding wrinkles and skewing of the substrate caused by feeding deviation, and providing a neat initial material for subsequent coating and cutting processes. The first feeding shaft 522 is located above the feeding rack 40, using gravity to assist the substrate to fall naturally, reducing additional contact wear between the substrate and the equipment, and ensuring that the substrate enters the conveying process in a relaxed posture, laying the foundation for the stable operation of subsequent processes.

[0062] Through the coordinated use of the second drive component 531, the second sliding seat 532, and the first take-up shaft 533, the second sliding seat 532 can slide along the bracket 51, flexibly adjusting the position of the first take-up shaft 533 (from one end of the frame 10 to the other end) according to the output position and width of the waste material after cutting. This ensures that the first take-up shaft 533 is precisely aligned with the output path of the cutting assembly 20, preventing the substrate from shifting or stacking during take-up and ensuring the neatness of the take-up roll. The second drive component 531 drives the first take-up shaft 533 to rotate, and the take-up tension can be precisely controlled by adjusting the drive speed. This avoids both insufficient tension causing the substrate to loosen or entangle, and excessive tension causing the substrate to stretch or tear. At the same time, the first take-up shaft 533 is located above the cutting assembly 20, effectively recovering the waste or leftover material generated during cutting, preventing waste from accumulating in the cutting area and affecting equipment operation.

[0063] In some embodiments, a second feeding section 11 and a second receiving section 12 are provided at the bottom of the frame 10. The second feeding section 11 and the second receiving section 12 are sequentially spaced apart on the frame 10 from one end to the other. Through the cooperative use of the second feeding section 11 and the second receiving section 12, the sequentially arranged second feeding section 11 and the second receiving section 12, along with the feeding rack 40, the film coating assembly 30, and the cutting assembly 20 on the frame 10, form a linear process of "bottom film feeding, film coating, cutting and separation, and bottom film recycling". After the base film is output from the second feeding section 11 at one end of the frame 10, it passes through the feeding rack 40, the coating assembly 30, the cutting assembly 20, and the coating assembly 30, and is then collected by the second receiving section 12 at the other end of the frame 10. This effectively avoids the turning and tangling of the base film during transport, ensuring that its bonding trajectory with the substrate is always aligned. This fundamentally reduces base film offset and wrinkles caused by chaotic paths, ensuring uniform coating. At the same time, the second feeding section 11 and the second receiving section 12 are located at the bottom of the frame 10, forming a layered layout with the first feeding section 52 and the second feeding section 11 located at the top of the frame 10. The base film's feeding and receiving path is independent of the substrate transport and cutting space, which avoids cross-interference between the base film and the substrate and equipment components, and makes full use of the idle space at the bottom of the frame 10, making the overall equipment structure more compact and adaptable to the spatial planning requirements of the production line.

[0064] Further, the second feeding section 11 includes a third sliding seat 111 and a second feeding shaft 112. The third sliding seat 111 is slidably disposed on the frame 10, and the second feeding shaft 112 is rotatably disposed on the third sliding seat 111. The second feeding shaft 112 is located below the feeding rack 40. The second receiving section 12 includes a third driving member 121, a fourth sliding seat 122 and a second receiving shaft 123. The fourth sliding seat 122 is slidably disposed on the frame 10, and the second receiving shaft 123 is rotatably disposed on the fourth sliding seat 122. The second receiving shaft 123 is located below the cutting assembly 20, and the output shaft of the third driving member 121 is connected to the second receiving shaft 123.

[0065] Through the cooperative use of the third sliding seat 111 and the second feeding shaft 112, the third sliding seat 111 can slide along the frame 10. The position of the second feeding shaft 112 (from one end of the frame 10 to the other end) can be adjusted according to the position of the feeding rack 40, the position of the substrate, and the pressing path of the coating assembly 30. This ensures that the bottom film output trajectory is completely aligned with the bonding area at the bottom of the substrate, guaranteeing uniform coating. The second feeding shaft 112 is located below the feeding rack 40, corresponding vertically to the substrate conveying path, so that the bottom film covers the bottom of the substrate.

[0066] Through the coordinated use of the third drive component 121, the fourth sliding seat 122, and the second take-up shaft 123, the fourth sliding seat 122 can slide along the frame 10. It can flexibly adjust the position of the second take-up shaft 123 according to the output direction and width of the bottom film after separation by the guide plate 35, ensuring that the recycling path perfectly matches the bottom film output trajectory. This avoids bottom film offset, entanglement, or edge wear during recycling, ensuring the neatness of the recycled roll. The third drive component 121 drives the second take-up shaft 123 to rotate. The take-up tension can be precisely controlled by adjusting the drive speed. If the tension is too low, the speed can be increased to prevent the bottom film from loosening and accumulating; if the tension is too high, the speed can be reduced to prevent the bottom film from stretching and breaking. Simultaneously, the second take-up shaft 123 is located below the cutting assembly 20, forming a physical isolation from the substrate conveying path and the cutting assembly 20 located above the frame 10. The bottom film's recycling path is independent of the substrate's flow trajectory, preventing the bottom film from entangled in the cutting assembly 20 or making secondary contact with the substrate. This also fully utilizes the space at the bottom of the frame 10, making the equipment layout more compact and improving the production line's space utilization.

[0067] In some embodiments, a control panel 13 is provided on the other side of the frame 10. The control panel 13 is equipped with a substrate feeding / receiving switch, a bottom film feeding / receiving switch, a tension adjustment button, and a digital display screen, which effectively realizes zoned control and improves the operational flexibility of the cutting and feeding device 100.

[0068] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
