Description

Technical Field

[0001] This invention relates to the field of copper foil packaging technology, specifically to an automated packaging device for finished lithium battery copper foil products. Background Technology

[0002] Copper foil is a key material for the negative electrode current collector in lithium-ion batteries. As battery performance requirements increase, the thickness of copper foil continues to decrease. Because ultra-thin copper foil has extremely high reactivity, it is highly susceptible to oxidation when exposed to air, thus affecting the battery's conductivity. Finished copper foil rolls must undergo strict sealed packaging before leaving the factory.

[0003] Current lithium-ion battery copper foil packaging processes face the following technical challenges: Copper foil rolls from different orders vary in outer diameter and width, making it difficult for existing packaging equipment to accurately align materials of different sizes at the same workstation, leading to packaging misalignment. Copper foil rolls are heavy and the foil material is extremely fragile; during automated conveying and positioning, rigid impacts can easily cause indentations or edge deformation. Traditional automated packaging devices often fail to tightly adhere the end faces when handling edge folding, resulting in inadequate subsequent heat-sealing and failing to meet the requirements for vacuum anti-oxidation storage. Lamination, folding, and vacuuming processes are often distributed across different equipment, increasing the number of material transfers, raising the risk of scratches, and limiting production efficiency.

[0026] To further illustrate the technical means and effects adopted by the present invention to achieve the intended purpose, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Detailed description follows.

[0027] Please see Figures 1-8This invention provides a technical solution: an automated packaging device for finished lithium-ion battery copper foil, comprising a main base 1, a material conveying structure mounted on the upper wall of the main base 1, and a material centering adjustment structure disposed between the material conveying structures. The material centering adjustment structure includes a pair of packaging rollers 2, a swinging part, a lifting part, and a buffer part. A fixed seat 3 is mounted on the main base 1, the swinging part is disposed on the fixed seat 3, and the lifting part is disposed within the swinging part. The upper end of the lifting part is connected to the pair of packaging rollers 2 by the buffer part. A packaging film covering structure is disposed on the fixed seat 3, and a compaction part and a folding part are disposed on the fixed seat 3. This device provides a unified installation platform through the main base 1, and the material conveying structure realizes the automated feeding and unloading of copper foil rolls. The material centering adjustment structure, through the cooperation of the swinging, lifting, and buffer parts, can adapt to copper foil rolls of different diameters and adjust their axis to coincide with the subsequent packaging station. The packaging film covering structure, the compaction part, and the folding part work together to complete the continuous packaging action from circumferential winding to end folding.

[0028] In this embodiment, the material conveying structure includes two rows of columns 4 arranged side by side along the material conveying direction. A conveying roller 5 is positioned between the upper ends of the columns 4. The conveying roller 5 is an electric roller, and a conveyor belt 6 is positioned outside the conveying roller 5. Two sets of conveying rollers 5 are respectively positioned at the input and output ends of the material centering and adjustment structure. The material conveying structure is inclined downwards along the material conveying direction. The material conveying structure uses the electric rollers to drive the conveyor belt 6, realizing the power transmission of the copper foil roll. By setting two independent conveying structures at the input and output ends, and adopting a downward inclination design along the conveying direction, using gravity assistance in conjunction with electric drive, the stability of the copper foil roll movement is ensured, and the switching between receiving and discharging materials at the centering and adjustment structure is facilitated.

[0029] This embodiment is further configured such that the swinging part includes a swing frame 7, which is rotatably disposed between fixed seats 3. A lifting platform 8 is slidably mounted on the swing frame 7. A lifting part is disposed between the lifting platform 8 and the swing frame 7. A buffer part is disposed between the lifting platform 8 and the packaging roller 2. A first motor 9 is mounted on the main base 1. A worm gear 10 is fixedly mounted on the driving end of the first motor 9. An arc plate 11 is disposed at the lower end of the swing frame 7. A worm gear tooth 12 is disposed on the arc plate 11. The worm gear 10 is meshed with the arc plate 11. The center of the arc plate 11 is located on the swinging axis of the swing frame 7. The swinging part drives the worm gear 10 through the first motor 9, and drives the arc plate 11 to rotate by utilizing the self-locking characteristic of the worm gear 10, thereby causing the entire swing frame 7 to tilt within a certain angle. On the one hand, the swinging part adjusts the receiving angle to smoothly receive the copper foil roll from the conveying structure. On the other hand, after packaging is completed, the finished product is actively unloaded by tilting in the opposite direction.

[0030] This embodiment is further configured such that the lifting unit includes a lifting motor 13, a fixed cylinder 14 is fixedly installed on the swing frame 7, a lifting cylinder 15 is fixedly installed at the lower end of the lifting platform 8, the lifting cylinder 15 is slidably installed inside the fixed cylinder 14, the lifting motor 13 is fixedly installed on the upper wall of the swing frame 7, a lead screw 16 is fixedly installed at the driving end of the lifting motor 13, and a threaded sleeve 17 is fixedly installed at the lower end of the lifting cylinder 15, the threaded sleeve 17 being threadedly connected to the lead screw 16; the lifting unit drives the lead screw 16 to rotate through the lifting motor 13, and uses the threaded transmission of the lead screw 16 to drive the lifting cylinder 15 to perform linear lifting and lowering motion within the fixed cylinder 14; its function is to precisely adjust the height of the packaging roller 2 according to the real-time diameter of the copper foil roll detected by the sensor, ensuring that the axis of the center hole of copper foil rolls of different specifications can be kept consistent with the axis of the end face pressure plate 36, providing a reference for automated pressing.

[0031] Through the synergistic effect of the material centering adjustment structure, the swinging part, driven by the first motor 9, engages with the worm gear 10 and the turbine gear 12 of the arc plate 11, thereby driving the swing frame 7 to flexibly adjust the receiving angle. The lifting part, through the cooperation of the lifting motor 13, lead screw 16, threaded sleeve 17, and fixed cylinder 14 with the lifting cylinder 15, achieves precise height adjustment of the lifting platform 8. Combined with the support and positioning of a pair of packaging rollers 2, it can adapt to copper foil rolls of different diameters in real time, ensuring that the axis of the copper foil roll always coincides with the axis of the end face pressure plate 36, providing a high-precision reference for subsequent vacuum sealing, and completely solving the problem of poor adaptability of traditional equipment to materials of different specifications.

[0032] In this embodiment, the buffer section includes two pairs of hydraulic cylinders 18 and a rectangular frame 19. A pair of packaging rollers 2 are rotatably mounted on the upper wall of the rectangular frame 19, and the two pairs of hydraulic cylinders 18 are fixedly mounted on the lifting platform 8. One end of each side of the rectangular frame 19 is rotatably connected to the telescopic end of one pair of hydraulic cylinders 18, and a sleeve 20 is rotatably mounted on the telescopic end of the other pair of hydraulic cylinders 18. The sleeve 20 is slidably mounted on the other end of each side of the rectangular frame 19. The buffer section uses the telescopic movement of the two pairs of hydraulic cylinders 18 to control the posture of the rectangular frame 19. During the receiving stage, the hydraulic cylinder 18 away from the receiving side extends as a physical limit to block the copper foil roll and prevent it from overstepping its bounds. During the packaging stage, the hydraulic cylinder 18 provides flexible support to absorb the impact energy when the copper foil roll roll rolls roll, protecting the surface of the copper foil from deformation caused by hard compression.

[0033] Flexible buffer design to avoid mechanical damage risk: The material centering and adjustment structure is equipped with a buffer part consisting of two pairs of hydraulic cylinders 18, a rectangular frame 19 and a sleeve 20. The hydraulic cylinders 18 can act as flexible blocking parts when the copper foil roll rolls in, effectively absorbing the kinetic energy of the material and avoiding rigid impact. In the support stage, flexible support is provided. With the sliding and rotating connection between the rectangular frame 19 and the sleeve 20, it can adapt to the surface shape of the copper foil roll, prevent the ultra-thin copper foil from being indented or deformed at the edge due to hard contact, and ensure the physical integrity of the copper foil roll.

[0034] In this embodiment, the packaging coating structure includes a film roller 21, a roller frame 22 is fixedly installed on the upper end of the fixed base 3, the film roller 21 is rotatably mounted on the roller frame 22, and a packaging coating 23 is provided on the film roller 21; the packaging coating structure provides continuous coating material for the entire packaging process through the film roller 21; the film roller 21 rotates freely on the roller frame 22, and with the tension control at the rear end, it ensures that the packaging film can be drawn onto the surface of the copper foil roll at a uniform speed and flat.

[0035] In this embodiment, the compaction section includes a first servo motor 24, which is fixedly installed in the fixed base 3 and located below the roller frame 22. A swing arm 25 is fixedly installed on the drive end of the first servo motor 24, and a compaction roller 26 is rotatably connected to the other end of the swing arm 25. The compaction section uses the first servo motor 24 to drive the swing arm 25 to precisely control the angle of the compaction roller 26. Its function is to press the front end of the packaging film onto the circumferential surface of the copper foil roll in the initial stage of film coating, and use the friction force generated by the rotation of the copper foil roll to drive the material film to be wound in multiple layers to ensure that the packaging layers are tightly bonded.

[0036] In this embodiment, a resistance heating wire is provided on a generatrix along the outer wall of the compaction roller 26; the resistance heating wire on the outer wall of the compaction roller 26 has a controlled heating function; when the packaging film is wound to a preset number of layers, the resistance heating wire is energized and heated instantly, melting the packaging film under the pressing state, and using the residual heat to thermally bond the end of the film to the outer ring of the packaged film sleeve, thereby realizing automatic film cutting and sealing.

[0037] In this embodiment, the folding section includes a folding roller 27. A shaft support 28 is provided on the upper end of the side wall of the fixed base 3. A bidirectional threaded rod 29 is provided on the shaft support 28. A pair of sliders 30 are slidably mounted on the side wall of the fixed base 3. Each pair of sliders 30 has a threaded hole. The pair of sliders 30 are threadedly connected to the bidirectional threaded rod 29. The pair of sliders 30 move in opposite directions but at the same speed. A second servo motor 31 is provided on the pair of sliders 30. A connecting rod 32 is fixedly mounted on the driving end of the second servo motor 31. The folding roller 27 is fixedly mounted on the other end of the connecting rod 32. An adjusting motor 33 is fixedly installed at one end of the shaft bracket 28. The driving end of the adjusting motor 33 is fixedly connected to one end of the bidirectional threaded rod 29. The folding roller 27 has a T-shaped cross section. The folding part drives the bidirectional threaded rod 29 through the adjusting motor 33, so that a pair of sliders 30 move synchronously towards the center or to both sides to adapt to copper foil rolls of different widths. The second servo motor 31 drives the connecting rod 32 to bring the T-shaped folding roller 27 close to the end face of the copper foil. The stepped surface of the T-shaped structure neatly squeezes and adheres the excess film that exceeds the end face of the copper foil to the end face of the copper foil, preparing for the final end face sealing.

[0038] In this embodiment, an end face frame 34 is fixedly installed on the main base 1. A pneumatic cylinder 35 is fixedly installed on the upper end of the end face frame 34. An end face pressure plate 36 is fixedly installed on the telescopic end of the pneumatic cylinder 35. The end face pressure plates 36 are respectively arranged on both sides of the material centering and adjustment structure. An annular electronic heating wire is provided on the end face pressure plate 36. An air extractor 37 is arranged in the middle of the end face pressure plate 36. Under the drive of the pneumatic cylinder 35, the end face pressure plate 36 applies axial pressure to the copper foil roll hole area from both sides. The air extractor 37 in the middle of the end face pressure plate 36 extracts air from the inside of the packaging through the reserved hole to form a negative pressure environment. The annular electronic heating wire then performs annular heat-sealing on the folded end film. This structure achieves a moisture-proof and oxidation-resistant vacuum fully sealed packaging effect.

[0039] The integrated process improves efficiency and reduces oxidation risk: The device integrates the material conveying structure column 4, conveying roller 5, conveyor belt 6, material centering and adjustment structure, packaging film coating structure film roller 21, roller frame 22, packaging film 23, first servo motor 24 of the compaction section, swing arm 25, compaction roller 26, folding roller 27 of the folding section, shaft support 28, bidirectional threaded rod 29, slider 30, second servo motor 31, connecting rod 32, adjustment motor 33, and end face sealing structure end face frame 34, pneumatic cylinder 35, end face pressure plate 36, and vacuum pump 37. Each process is completed continuously on the same main base 1. The entire process of material input, centering, film coating, compaction, folding to vacuum heat sealing is automated, reducing the number of material transfers and environmental exposure time, which not only reduces the oxidation risk of ultra-thin copper foil, but also significantly improves the efficiency of finished product packaging operations.

[0040] Strong sealing performance ensures storage quality: The resistance heating wire on the outer wall of the compaction roller 26 can automatically cut the film and heat-bond the tail after the film is wrapped, ensuring a tight fit of the film on the circumferential surface; the folding part is driven by the bidirectional threaded rod 29 driven by the adjustment motor 33 to drive the slider 30 to move synchronously in the opposite direction, and with the T-shaped folding roller 27 driven by the second servo motor 31, the redundant film can be neatly attached to the end face of the copper foil roll; the end face pressure plate 36 is axially pressurized under the drive of the pneumatic cylinder 35, and its built-in annular resistance heating wire works with the middle vacuum pump 37 to complete the annular heat-melting sealing in a vacuum environment. The sealing is strong and can effectively isolate air and moisture, meeting the long-term anti-oxidation storage requirements of lithium battery copper foil.

[0041] Working principle: The finished roll of lithium battery copper foil to be packaged is input from the front end of the material conveying structure along the conveying direction; the material centering and adjustment structure enters the standby state: the first motor 9 drives the worm gear 10 to rotate, and through meshing with the worm gear 12 on the arc plate 11, drives the swing frame 7 to swing around its axis, adjusting the angle of the packaging roller 2 to smoothly receive the rolling copper foil roll; the lifting part is started, and the lifting motor 13 drives the threaded sleeve 17 to move through the lead screw 16, adjusting the height position of the lifting platform 8 and the packaging roller 2 to adapt to the diameter of the current specification copper foil roll;

[0042] The buffer section is activated, and the telescopic ends of a pair of hydraulic cylinders 18 located away from the receiving side extend upward to act as a physical blocking position, so that the copper foil roll that rolls in stops between the two packaging rollers 2; after the copper foil roll is in place, the swing frame 7 returns to the horizontal state; the lifting platform 8 further fine-tunes the height according to the preset parameters, so that the central axis of the copper foil roll is horizontally aligned with the axis of the pressure plates 36 on both sides, thus completing the precision centering.

[0043] The packaging film-coating structure begins to supply film. The first servo motor 24 drives the swing arm 25 to rotate, bringing the compaction roller 26 close to the circumference of the copper foil roll and pressing the packaging film 23 onto the copper foil surface. The packaging roller 2 rotates, driving the copper foil roll to rotate and continuously winding the film around the outer circumference of the copper foil. After reaching the preset number of layers, the resistance heating wire on the busbar of the compaction roller 26 is energized and heats up instantly, melting the outer layer of film and using the residual heat to complete the tail heat bonding, forming a tight outer ring film sleeve.

[0044] The adjustment motor 33 starts and drives the bidirectional threaded rod 29 to rotate, which drives a pair of sliders 30 to move inward or outward synchronously on the shaft support 28, so that the folding roller 27 is accurately aligned with the side wall edges at both ends of the copper foil roll; the second servo motor 31 drives the connecting rod 32 to swing, so that the folding roller 27 with the T-shaped cross section presses against the end face of the copper foil roll. During the rotation, the cylindrical coating that exceeds the end face is neatly folded inward, so that it is tightly attached to the end face of the copper foil roll.

[0045] The pneumatic cylinder 35 drives the end face pressure plates 36 on both sides to extend towards the center and press them tightly against the end face of the copper foil roll that has been folded. The vacuum pump 37 is turned on to extract air from inside the packaging through the vacuum channel in the middle of the end face pressure plate 36, so that the inside reaches the preset vacuum or negative pressure state. The annular electronic heating wire on the end face pressure plate 36 is energized to perform annular heat-melting seal on the overlapping folded film. After the packaging is completed, the pneumatic cylinder 35 retracts the end face pressure plate 36, and the compacted part and the folded part return to their original positions. The swing frame 7 tilts and swings in the discharge direction, while the extension end of the hydraulic cylinder 18 on the other side extends to assist in pushing, so that the finished copper foil roll that has been packaged rolls smoothly rolls onto the conveyor roller 5 at the output end and is discharged through the conveyor belt 6. All mechanisms of the equipment return to the initial waiting state and are ready for the next packaging cycle.
