Description

Technical Field

[0001] This application relates to the technical field of equipment used in the electrolytic production of copper foil, and more particularly to a copper foil production equipment. Background Technology

[0002] Existing copper foil production equipment typically includes an mounting platform, an anode shell, a cathode roller, a cathode connecting copper busbar, and a power supply. The anode shell is mounted on the mounting platform, and the cathode roller is rotatably mounted on the anode shell and connected to the power module via the cathode connecting copper busbar. However, to meet the flexibility requirements of the cathode roller's conductive connection, existing copper foil production equipment usually employs a flexible connection structure to achieve conductivity between the cathode roller and the power supply circuit. Commonly used flexible connections are mainly divided into two categories: copper sheet flexible connections and braided flexible connections. Copper sheet flexible connections are made by stacking multiple layers of thin copper sheets, relying on the bending deformation of the copper sheets themselves to provide flexibility; braided flexible connections are formed by braiding copper wires, achieving flexible adaptation through the loose deformation of the braided structure.

[0003] However, the flexible connection structure itself has a certain weight, which generates a downward sag force during installation and use. This downward sag force exerts a unidirectional downward pull on the cathode roller, disrupting the force balance of the cathode roller's rotation. Furthermore, due to factors such as installation accuracy and uneven deformation of the flexible connection structure itself, the forces on the flexible connections on both sides or around the cathode roller are uneven, resulting in inconsistent downward forces on the left and right sides and in different directions. This leads to eccentric force on the cathode roller. Consequently, existing flexible connection structures cannot simultaneously achieve conductive flexibility, balanced force distribution, and stable operation, failing to meet the requirements of large-scale and high-precision copper foil production equipment. Summary of the Invention

[0030] The following description provides preferred embodiments for carrying out this application; however, this description is for the purpose of illustrating the general principles of this application and is not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0031] Electrolytic copper foil is a core material for electronic components such as lithium batteries and printed circuit boards. The cathode roller, as a core component in electrolytic copper foil production equipment, rotates continuously at high speed during the copper foil electrolytic forming process, simultaneously performing the dual functions of conductivity and forming. Under continuous operation, the cathode roller must ensure stable current conduction, maintain a uniform electric field on its surface, extend its service life, and avoid problems such as burning and wear caused by localized overload and poor contact. Simultaneously, it must adapt to the rotational movement of the cathode roller, eliminating stress tension and vibration noise caused by rigid connections, ensuring smooth operation without eccentricity or wobbling, and ultimately guaranteeing uniform copper foil thickness and a satisfactory surface finish. Therefore, the conductive connection structure between the cathode roller and the power supply components needs to possess sufficient flexibility and elasticity to achieve stable high-current transmission, adapt to the rotational displacement of the cathode roller, buffer stress during operation, and balance conductivity life and operational stability.

[0032] Existing copper foil production equipment typically includes an mounting platform, an anode shell, a cathode roller, a cathode connecting copper busbar, and a power supply. The anode shell is mounted on the mounting platform, and the cathode roller is rotatably mounted on the anode shell and connected to the power module via the cathode connecting copper busbar. However, to meet the flexibility requirements of the cathode roller's conductive connection, existing copper foil production equipment usually employs a flexible connection structure to achieve conductivity between the cathode roller and the power supply circuit. Commonly used flexible connections are mainly divided into two categories: copper sheet flexible connections and braided flexible connections. Copper sheet flexible connections are made by stacking multiple layers of thin copper sheets, relying on the bending deformation of the copper sheets themselves to provide flexibility; braided flexible connections are formed by braiding copper wires, achieving flexible adaptation through the loose deformation of the braided structure. However, the flexible connection structure itself has a certain weight, and under installation and use conditions, this weight will generate a downward sagging force. The downward pull of the flexible connection structure itself exerts a unidirectional downward traction on the cathode roller, disrupting the force balance of the cathode roller's rotation. Simultaneously, factors such as installation accuracy and uneven deformation of the flexible connection structure itself lead to uneven force distribution on the flexible connections on both sides or around the cathode roller, resulting in inconsistent downward pull on the left and right sides and in different directions, thus causing eccentric force distribution on the cathode roller. This force imbalance directly affects the rotational stability of the cathode roller, causing eccentric wobbling and operational vibration. Mild cases result in uneven thickness and surface defects in the electrolytically formed copper foil, reducing the quality and yield of the finished copper foil. More severe cases exacerbate surface wear on the cathode roller, cause poor local conductive contact, shorten the cathode roller's lifespan, increase equipment operating noise and failure rate, and raise production and maintenance costs. In summary, the existing flexible connection structure cannot simultaneously achieve conductive flexibility, balanced force distribution, and stable operation, failing to meet the requirements of large-scale and high-precision copper foil production equipment. Therefore, improvements to the conductive connection structure of the cathode roller are urgently needed.

[0033] Please see Figure 1 , Figure 1 This is a schematic diagram of the copper foil production equipment provided in this application embodiment. The copper foil production equipment 100 includes a mounting platform 1, a foil production machine 2, and a power supply connection mechanism 3. The foil production machine 2 includes an anode shell 21 and a cathode roller 22. The anode shell 21 is fixedly connected to the mounting platform 1, and the cathode roller 22 is rotatably disposed on the anode shell 21. The power supply connection mechanism 3 includes a support frame 30, an elastic component 40, a power supply component 60, and a conductive connection component 50. The elastic component 40 is elastically disposed between the support frame 30 and the mounting platform 1. The power supply component 60 is fixedly connected to the support frame 30. The conductive connection component 50 is fixedly connected between the cathode roller 22 and the power supply component 60.

[0034] In the copper foil production equipment 100 provided in this application embodiment, an elastic component 40 is provided between the support frame 30 and the mounting platform 1. The power supply component 60 is fixed on the support frame 30, and the conductive connection component 50 is fixedly connected between the cathode roller 22 and the power supply component 60. On the one hand, the elastic force of the elastic component 40 itself can support the power supply component 60 and the conductive connection component 50. Thus, the upward compensation force provided by the elastic component 40 to the conductive connection component 50 can counteract the shaking displacement of the cathode roller 22, improve the coaxiality of the cathode roller 22 during rotation, enhance the smoothness and reliability of the cathode roller 22 rotation, reduce mechanical transmission noise and component wear, and meet the requirements of the copper foil production equipment 100. The large-scale and high-precision requirements are met. At the same time, the flexible support characteristics of the elastic component 40 replace the rigid self-weight load of the traditional soft connection structure, making the connection between the conductive connection component 50 and the power supply component 60 more evenly stressed. This reduces the risk of fatigue fracture of the conductive connection component 50 due to local stress concentration and extends the life cycle of the copper foil production equipment 100. On the other hand, the support frame 30, as a basic fixing component, supports the power supply component 60 and supports the mounting platform 1 through the elastic component 40, thereby ensuring the relative stability of key components such as the anode shell 21 and the cathode roller 22, and isolating the influence of external ground vibration or its own operating vibration, thereby improving the thickness uniformity and operational reliability of copper foil production.

[0035] It should be noted that, Figure 1 The purpose is merely to schematically describe the arrangement of the mounting platform 1, the foil-making machine 2, and the power supply connection mechanism 3, and is not to specifically limit the connection positions, connection relationships, and specific structures of each component. Figure 1 The structure of the copper foil production equipment 100 illustrated in this application embodiment is merely a schematic diagram and does not constitute a specific limitation on the copper foil production equipment 100. In other embodiments of this application, the copper foil production equipment 100 may include... Figure 1 The copper foil production equipment 100 may include, but is not limited to, circulating pumps, pipelines, and temperature control modules, as shown in the diagram. The circulating pump is connected to the pipelines to achieve closed-loop transport of the electrolyte within the anode shell 21 between the preparation tank and the electrolytic cell, ensuring stable flow. The temperature control module can control the electrolyte temperature within a suitable temperature range through structures such as heat exchangers and heating tubes.

[0036] For example, in this embodiment, the number of power supply connection mechanisms 3 can be set to two. The two power supply connection mechanisms 3 are respectively connected to both ends of the cathode roller 22 along its axial direction. Simultaneous introduction of current from both ends of the cathode roller 22 can reduce current attenuation and loss over a long distance on the roller body, making the current density distribution more uniform along the roller surface axially, thus improving the thickness and performance consistency of the electroplated layer or electrolytic product (such as copper foil). Of course, in an optional embodiment, the number of power supply connection mechanisms 3 can also be set to one. The power supply connection mechanism 3 is connected to one end of the cathode roller 22 along its axial direction.

[0037] Please refer to the following: Figure 1 and Figure 2 , Figure 2 This is a schematic diagram of a portion of the structure of the copper foil production equipment provided in this application embodiment. The anode shell 21 serves as the anode electrode of the electrolysis system. The anode shell 21 is provided with a receiving groove 2101. The receiving groove 2101 is used to contain the electrolyte. The electrolyte contains copper ions. A through hole 2102 is also provided on the top of the anode shell 21. The through hole 2102 communicates with the receiving groove 2101 and is used for the cathode roller 22 to pass through.

[0038] The cathode roller 22 serves as the cathode electrode of the electrolysis system. The cathode roller 22 includes a cathode roller body 221 and a cathode post 222. The cathode roller body 221 and the cathode post 222 are coaxial and electrically connected, and are rotatably disposed within the through hole 2102 of the anode shell 21. This allows the cathode roller body 221 to be immersed in the electrolyte and continuously rotate with the cathode post 222, thereby precipitating copper ion crystals on the roller surface of the cathode roller body 221. Specifically, the cathode roller body 221 provides rigid support and a conductive substrate. The material of the cathode roller body 221 may include, but is not limited to, stainless steel, titanium steel, etc. The cathode post 222 is connected to the power supply component 60 via a conductive connection component 50, thereby enabling the cathode post 222 to serve as the current introduction point of the cathode roller 22 and maintain a stable cathode potential on the roller surface of the cathode roller body 221.

[0039] Understandably, under the influence of an electric field, copper ions in the electrolyte gain electrons on the surface of the cathode roller 22, undergoing an electrodeposition reduction reaction to form copper atoms. These copper atoms continuously crystallize and accumulate on the surface of the cathode roller 221, forming a uniform metallic copper foil. Furthermore, as the cathode roller 22 rotates slowly, the formed copper foil is carried out of the electrolyte within the anode shell 21 and continuously peeled off from the surface of the cathode roller 221, achieving continuous production of copper foil.

[0040] In some optional embodiments, a cooling channel is provided inside the roller body, thereby facilitating the heat generated by the electrolytic reaction through the cooling medium in the cooling channel, stabilizing the roller surface temperature of the cathode roller body 221, and improving the uniformity of the microstructure and thickness of the copper foil.

[0041] The cathode roller 22 has a rotation axis. For accuracy, all references to direction in this text shall be expressed in terms of direction. Figure 1 and Figure 2 For reference, the term "length direction Y" can refer to the direction perpendicular to the rotation axis of the cathode roller 22 in the horizontal plane, i.e. Figure 1 The X-axis direction in the text. The term "width direction X" can refer to the direction parallel to the rotation axis of the cathode roller 22, or the arrangement direction of the power supply component 60 and the anode shell 21, i.e. Figure 2 The Y-axis direction in the diagram. The term "height direction Z" can refer to the direction perpendicular to the bearing surface of the copper foil production equipment 100, that is, the arrangement direction of the mounting platform 1 and the foil production machine 2. Figure 2 The Z-axis direction is defined in the diagram. The width direction (X), length direction (Y), and height direction (Z) constitute the three orthogonal directions of the copper foil production equipment 100, and can be customized according to the specific structure of the product and the viewing angle presented in the accompanying drawings. This application embodiment does not impose specific limitations. The horizontal plane refers to a plane parallel to the earth's reference plane. Exemplarily, the horizontal plane is parallel to the bearing surface of the copper foil production equipment 100.

[0042] Please refer to the following: Figure 2 and Figure 3 , Figure 3 yes Figure 1 The first exploded view shows the power supply connection mechanism of the copper foil production equipment 100. The elastic component 40 includes multiple elastic elements 410. These multiple elastic elements 410 are arranged at intervals along the length Y direction of the copper foil production equipment 100. Each elastic element 410 includes at least two elastic members 411, which are also arranged at intervals along the width X direction of the copper foil production equipment 100 and elastically positioned between the mounting platform 1 and the support frame 30. Thus, the multiple elastic members 411 can form a regionalized, multi-point elastic support, and a matrix-type elastic support system that resists multiple degrees of freedom such as vertical, pitch, roll, and horizontal torsion. The elastic support is stable and uniform, providing the highest precision mechanical guarantee for the stability of the electric field between the cathode roller 22 and the anode shell 21. This is suitable for large, wide-width copper foil production equipment 100, effectively ensuring the stability of the two ends of the long cathode roller 22 and the entire electrode spacing, and improving the thickness uniformity of the wide-width copper foil. For example, in this embodiment, the elastic member 411 can be a spring. Of course, in one possible embodiment, the elastic element 411 can also be a sheet or other elastic structure.

[0043] Please refer to the following: Figures 1 to 3In an optional embodiment, each elastic component 410 further includes at least one guide rod 412. The first end of the guide rod 412 is fixedly connected to the mounting platform 1. The second end of the guide rod 412 is slidably connected to the support frame 30 along the extension / retraction direction F of the elastic member 411, and is arranged to avoid contact with the power supply component 60. Thus, on the one hand, the guide rod 412 can guide the elastic member 411 to extend and retract along the extension direction of the guide rod 412, ensuring that the anode shell 21 and the cathode roller 22 always maintain a stable relative posture; on the other hand, the slidable connection between the guide rod 412 and the support frame 30, and the avoidance arrangement between the guide rod 412 and the power supply component 60, can avoid mechanical interference and short-circuit risks between the guide rod 412 and the power supply component 60 during sliding, ensuring smooth mechanical movement and improving the electrical safety and operational reliability of the equipment.

[0044] In another alternative embodiment, the first end of the guide rod 412 is fixedly connected to the support frame 30, and the second end of the guide rod 412 is slidably connected to the mounting platform 1 along the extension and retraction direction F of the elastic member 411, thereby improving the flexibility of the installation position of the guide rod 412 and avoiding interference between the guide rod 412 and the power supply component 60.

[0045] The number of guide rods 412 corresponds one-to-one with the number of elastic elements 411, with each elastic element 411 fitted onto the outer side of the corresponding guide rod 412. Thus, the elastic elements 411 and guide rods 412 are coaxially arranged, restricting the support frame 30, the power supply component 60 mounted on the support frame 30, and the conductive connection component 50 connected to the power supply component 60 to only perform vertical lifting movements, preventing random horizontal drift or swaying. This ensures that the anode shell 21 and the cathode roller 22 maintain a stable relative posture, while simultaneously improving overall rigidity while ensuring elastic buffering, resisting vibration and lateral forces on the cathode roller 22 during production, improving the uniformity of copper foil thickness and surface quality, reducing radial space occupation, simplifying the overall structure of the elastic component 410, and facilitating layout within limited equipment installation space.

[0046] In some optional embodiments, the elastic component 410 further includes a connecting plate 413. At least one guide rod 412 is fixedly connected to the mounting platform 1 via the connecting plate 413. Thus, connecting the guide rod 412 to the mounting platform 1 via the connecting plate 413 effectively increases the force-bearing contact area, avoids local stress concentration caused by direct connection of the guide rods 412, prevents deformation or damage to the mounting platform 1, and improves structural strength and reliability. Simultaneously, the connecting plate 413 can uniformly fix one or more guide rods 412, ensuring the parallelism and spacing accuracy between the guide rods 412, making the guiding movement more regular. Furthermore, it enhances the overall rigidity of the elastic component 410, reduces swaying and wobble during movement, simplifies assembly processes, facilitates positioning and installation, improves assembly efficiency, and reduces processing and debugging difficulty.

[0047] For example, the multiple connecting plates 413 in the multiple elastic components 410 can be independently arranged and spaced apart, so that each elastic component 410 can be independently adjusted in height, elastic force and guiding posture. During maintenance, it can be disassembled and replaced individually without overall disassembly and assembly, which facilitates later debugging and maintenance. At the same time, each elastic component 410 provides independent support and buffering, so that force fluctuations or elastic changes at one position will not be transmitted or affect other areas, making the force on the mounting platform 1 more balanced, suppressing the spread of local disturbances and improving operational stability. In some optional embodiments, the multiple connecting plates 413 in the multiple elastic components 410 can be integrated into a single structure, thereby improving the overall rigidity and integrity of the elastic components 410, avoiding relative displacement, twisting or local deformation caused by uneven force distribution when the multiple connecting plates 413 are set separately, making the posture of the mounting platform 1 more stable and non-skewed during elastic floating, and ensuring that the anode shell 21 and cathode roller 22 always maintain a stable relative posture; at the same time, it realizes the modular overall installation of the elastic components 40, improving assembly efficiency and reducing processing and debugging difficulty.

[0048] In some optional embodiments, the elastic component 410 further includes two washers 414. The two washers 414 are fitted onto the outer side of the guide rod 412. The elastic element 411 elastically abuts against the two washers 414. Thus, on the one hand, the elastic element 411 continuously pushes against the two washers 414, keeping the mating surfaces between the elastic element 411 and the washers 414 in a taut state, eliminating the axial clearance between the guide rod 412 and the sliding element, and preventing slippage, impact, and abnormal noise during movement; on the other hand, when external force impacts or vibrations are transmitted to the washers 414, the elastic element 411 can absorb some energy, reducing the impact load and protecting the guide rod 412 and the components associated with the elastic element 411. At the same time, the arrangement of the washers 414 can increase the force-bearing area of ​​the elastic element 411. With the elastic element 411 centrally located, the force transmission is more uniform, less prone to uneven loading and jamming, and the guidance is smoother.

[0049] In an optional embodiment, the elastic component 410 further includes a telescopic adjustment structure 415. The telescopic adjustment structure 415 is used to adjust the amount of extension and retraction of the elastic element 411. Thus, on the one hand, the telescopic adjustment structure 415 can actively compensate for accumulated errors caused by factors such as the curvature of the anode shell 21, the roundness of the cathode roller 22, and the flatness of the support frame 30, thereby reducing the precision requirements of the parts. By adjusting, the anode shell 21 and the cathode roller 22 achieve a uniform electrode pitch along the entire height direction Z, reducing manufacturing costs and ensuring that each copper foil production equipment 100 achieves optimal working conditions. Simultaneously, the telescopic adjustment structure 415 allows the copper foil production equipment 100 to quickly and accurately switch process parameters without replacing mechanical parts; simply changing the compression of the elastic element 411 through the telescopic adjustment structure 415 sets a new electrode pitch, improving the flexibility of the copper foil production equipment 100. On the other hand, changing the amount of expansion and contraction (i.e., pre-compression) of the elastic element 411 can not only change the static position of the cathode roller 22, but also change the initial stiffness and preload of the elastic component 410 to dynamic forces. For example, when the pre-compression of the elastic element 411 increases, the rigidity of the elastic element 411 increases, and the mounting platform 1's ability to resist vibration is enhanced, but the thermal expansion compensation ability is weakened. Conversely, when the pre-compression of the elastic element 411 decreases, the rigidity of the elastic element 411 weakens, and the vibration isolation effect is better, but the electrode pitch may fluctuate more easily under the impact of the electrolyte. Thus, the expansion and contraction adjustment structure 415 can become a tool for adjusting the dynamic response characteristics of the copper foil production equipment 100 to adapt to different production speeds (cathode roller 22 speed) or electrolyte flow rates. The expansion and contraction adjustment structure 415 can be, but is not limited to, a threaded screw, an adjusting nut, a wedge block, etc. For example, the expansion and contraction adjustment structure 415 can be configured as an adjusting nut, and the guide rod 412 is provided with a thread that is screwed to the adjusting nut, thereby realizing the adjustment of the pre-compression of the elastic element 411. It should be noted that the term "pre-compression amount" refers to the amount of expansion and contraction of the elastic element 411 when the cathode roller 22 is in a stationary state.

[0050] For example, the support frame 30 includes a support plate 31 and a support frame 32. An elastic member 40 is provided between the support plate 31 and the mounting platform 1. The support frame 32 is mounted on the support plate 31 and a power supply component 60 is mounted thereon. Thus, on the one hand, the support plate 31 can evenly distribute the local pressure of the elastic member 40, preventing the support frame 32 from tilting, and the support frame 32 provides a high-rigidity, low-deformation mounting base for the power supply component 60, thereby improving the reliability and stability of the connection between the power supply component 60 and the support frame 32, and improving the stability and reliability of the electrical connection between the power supply component 60 and the conductive connection component 50; on the other hand, the support frame 32 can promptly conduct the heat transferred by the cathode roller 22 to the external environment, reducing the impact of heat on the power supply component 60 on the support frame 32, while the floating of the elastic member 40 can also slightly block the heat conduction path.

[0051] In one optional embodiment, the support frame 30 further includes a plurality of support sleeves 33. The plurality of support sleeves 33 are disposed between the support plate 31 and the support frame 32, and the support sleeves 33 are sleeved on the outside of the guide rod 412. Therefore, on the one hand, the support sleeve 33, supported between the support plate 31 and the support frame 32, enhances the overall structural rigidity of the support frame 30, making it less prone to deformation, and improves the installation accuracy of the elastic component 40 and the support frame 30 bracket. At the same time, as a rigid support component, the support sleeve 33 evenly transfers the load of the support plate 31 to the support frame 32, reducing local pressure deformation of the support plate 31 or the guide rod 412, and improving the overall structural strength and durability of the support frame 30 and the elastic component 40. On the other hand, the support sleeve 33, fitted on the outside of the guide rod 412, can protect the surface of the guide rod 412 from scratches and bumps, and also play an auxiliary positioning role for the guide rod 412, improving the installation coaxiality and stability of the guide rod 412, reducing the shaking and swaying of the support frame 30 and the power supply component 60 and conductive connection component 50 installed on the support frame 30 during the movement, and improving the smoothness and reliability of the buffer action.

[0052] The support frame 30 and the anode shell 21 are spaced apart in the width direction X of the copper foil production equipment 100. Therefore, by arranging the support frame 30 and the anode shell 21 at a distance in the width direction X of the copper foil production equipment 100, on the one hand, the support frame 30 and the anode shell 21 can be staggered and not contact each other during assembly and operation, effectively preventing structural interference such as friction and collision, improving the operational stability of the copper foil production equipment 100, and improving the smoothness and reliability of the suspension connection of the support frame 30 relative to the mounting platform 1 along the height direction Z of the copper foil production equipment 100 via the elastic component 40; on the other hand, it can avoid the support frame 30 causing interference to the surrounding electric field and electrolyte flow field of the anode shell 21. The spacing between the support frame 30 and the anode shell 21 reduces interference, resulting in a more uniform electric field distribution and smoother electrolyte flow, thereby improving the uniformity of copper foil thickness and surface quality. Simultaneously, the spatial separation provides physical isolation, reducing the risk of accidental electrical conduction and leakage between the support frame 30 and the anode shell 21, lowering the risk of short circuits, and enhancing the safety and stability of the electrical system of the copper foil production equipment 100. Furthermore, the spaced arrangement between the support frame 30 and the anode shell 21 forms a heat dissipation channel, facilitating the timely dissipation of heat generated during the operation of the anode shell 21, preventing localized overheating, stabilizing the electrolysis process temperature, and improving the long-term reliability of the copper foil production equipment 100.

[0053] In this embodiment, for example, the power supply component 60 includes a plurality of power modules 610. The plurality of power modules 610 are spaced apart circumferentially along the cathode roller 22. The conductive connection component 50 includes a cathode connector 51 and a plurality of cathode connection rows 52. The cathode connector 51 is conductively connected to the cathode roller 22. A first end of each cathode connection row 52 is fixedly connected to the cathode connector 51, and a second end of each cathode connection row 52 is fixedly connected to a power module 610. Therefore, on the one hand, the multiple power modules 610 are spaced apart circumferentially along the cathode roller 22, so that the overall gravity, electromagnetic attraction, and vibration load of the power supply component 60 are distributed and transmitted to the support frame 30 in the circumferential direction, and then act on the elastic component 40. This reduces the single-point load of a single power module 610, making the elastic component 40 less prone to local overload, off-center load, crushing, or permanent deformation, and making the force on the elastic component 40 more balanced during compression and rebound. At the same time, the power modules 610 will generate periodic electromagnetic vibration and current pulsation during electrolysis. The multiple power modules 610 distributed circumferentially along the cathode roller 22 can make the vibration energy act evenly on the elastic component 40, reduce local resonance and stress concentration, improve the overall buffering and vibration isolation effect, and protect the guide rod 412 and the precision mating surface. On the other hand, using multiple power modules 610 to supply power to the cathode roller 22 in parallel distributes the total current to multiple branches, reduces the current density of a single cathode connection bar 52, reduces heat generation, voltage drop and loss, and improves the stability of long-term continuous operation. Simultaneously, multiple power modules 610 independently supply power along the circumference of the cathode roller 22, achieving multi-point synchronous power feeding. Current enters the cathode roller 22 synchronously from multiple circumferential positions, avoiding local current concentration or current lag caused by single-point power supply, and making the electric field on the surface of the electrode roller more uniform in the circumferential direction. On the other hand, the cathode connector 51 is directly conductively connected to the cathode roller 22, and then connected to each power module 610 nearby through multiple cathode connection bars 52, thereby shortening the conductive path, reducing line resistance and voltage drop, and improving power utilization. At the same time, the two ends of the cathode connection bar 52 are rigidly fixed to the cathode connector 51 and the power module 610 respectively, ensuring a firm connection and avoiding problems such as poor contact, arcing, or overheating caused by vibration and thermal expansion and contraction, thus improving the reliability and safety of long-term conductivity. Furthermore, by using multiple power modules 610 and multiple cathode connection bars 52 in a one-to-one correspondence, a single power module 610 can be repaired or replaced individually when it fails, without affecting the downtime of the entire machine, thus improving the maintainability and production efficiency of the copper foil production equipment 100.

[0054] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 3An enlarged view of the power supply module of the power supply connection mechanism of the copper foil production equipment. The power supply module 610 includes a power supply body 6101, a cathode terminal 6102, a cathode connecting post 6103, and a buffer 6104. The first end of the cathode terminal 6102 is connected to the cathode connecting post 6103, and the second end of the cathode terminal 6102 is connected to the cathode connecting bar 52. The cathode connecting post 6103 is movably connected between the power supply body 6101 and the cathode terminal 6102. The buffer 6104 is elastically disposed between the cathode terminal 6102 and the power supply body 6101. Therefore, on the one hand, the cathode connecting post 6103 can be movably connected between the power supply body 6101 and the cathode terminal 6102. Combined with the elastic support of the buffer 6104, it can adaptively compensate for assembly errors, thermal expansion and contraction deformation, and equipment vibration displacement, ensuring a reliable and secure power supply connection and preventing poor contact. On the other hand, the buffer 6104 provides a continuous elastic pre-tightening force to the cathode terminal 6102 and the cathode connecting post 6103, keeping the conductive contact surface in a stable and pressed state, effectively reducing contact resistance and minimizing heating, arcing, and ablation under high current conditions. Furthermore, the copper foil production equipment... Vibrations and impacts generated during operation can be absorbed by the elastic deformation of the buffer 6104, avoiding wear, loosening or breakage of the contact surface caused by rigid connection, and extending the service life of conductive connection component 50. On the other hand, the floating elastic connection can maintain the continuity and stability of the conductive path, reduce current fluctuations and voltage drops, make the power supply more stable, and help to achieve uniform electric field on the surface of cathode roller 22 and improve the uniformity of copper foil thickness. At the same time, the movable connection structure combined with elastic buffer can relax the requirements for processing accuracy and assembly position accuracy, reduce assembly difficulty, improve production efficiency, and facilitate later maintenance and replacement.

[0055] Exemplarily, the cathode terminal 6102 is connected to the first end of the power supply body 6101 along the extending direction of the power module 610, and is located on the end face of the power supply body 6101 facing the cathode connection row 52, ​​thereby shortening the connection path between the cathode terminal 6102 and the cathode connection row 52. The cathode connection post 6103 is movably embedded in the power supply body 6101 and partially extends out of the power supply body 6101. The buffer 6104 can be a spring. Of course, in some embodiments, the buffer 6104 can be omitted, that is, the cathode connection post 6103 is fixedly connected to the power supply body 6101, and this application embodiment does not specifically limit this. Of course, in one possible embodiment, the buffer 6104 can also be a spring sheet or other elastic structure.

[0056] Exemplarily, the power module 610 also includes an anode terminal 6105. The anode terminal 6105 is used to connect to the anode connection bar. Specifically, the anode terminal 6105 is disposed at the second end of the power body 6101 along the extension direction of the power module 610, and is located on the side of the power body 6101 facing the anode housing 21, thereby shortening the connection path between the anode terminal 6105 and the anode connection bar.

[0057] Please refer to it again. Figure 2 and Figure 3 In this embodiment, for example, the power supply component 60 includes two power supply assemblies 61. The two power supply assemblies 61 are symmetrically arranged relative to the cathode connector 51, and each power supply assembly 61 includes one or more power modules 610. The conductive connection component 50 includes two cathode busbar assemblies 520. The two cathode busbar assemblies 520 are symmetrically arranged relative to the cathode connector 51 and are conductively connected to the two power supply assemblies 61 in a one-to-one correspondence. Each cathode busbar assembly 520 includes one or more cathode connection bars 52. Therefore, the two power supply components 61 and the corresponding cathode busbar components 520 are symmetrically arranged relative to the cathode connector 51. On the one hand, this allows the current to flow symmetrically into the cathode roller 22 from both sides, improving the uniformity of the current density in the circumferential and axial directions of the cathode roller 22, improving the symmetry of the electrolytic electric field, and enhancing the uniformity of copper foil thickness and the quality of the board surface. At the same time, the total power supply current is symmetrically distributed by the two sets of power supply components 61, resulting in a smaller current in a single cathode busbar 52, significantly reducing line voltage drop, resistance loss, and heat generation, thus improving power supply stability and safety. On the other hand, the symmetrical arrangement ensures that the weight, electromagnetic force, and vibration load of the power supply component 60 are symmetrically distributed, avoiding eccentric torque caused by excessive load on one side, reducing the tilt of the support frame 30 and the jamming of the guide rod 412, and making the elastic component 40 more stable under force. Meanwhile, the length, direction, and impedance of the cathode busbar components 520 on both sides are basically the same, which can reduce the potential difference between the cathode busbar components 520 on both sides, avoid current circulation, local arcing, or local over-electrolysis, improve the current output quality, and improve the yield of copper foil production.

[0058] For example, in this embodiment, one or more power modules 610 include at least one of a first power module 611, a second power module 612, and a third power module 613. The extension direction of the first power module 611 is parallel to the height direction Z of the copper foil production equipment 100. The extension direction of the second power module 612 is parallel to the length direction Y of the copper foil production equipment 100. The extension direction of the third power module 613 intersects the height direction Z and the length direction Y of the copper foil production equipment 100. Thus, on the one hand, by arranging the power modules 610 along the height direction Z, the length direction Y, and diagonally, the scattered space inside the equipment can be fully utilized to achieve a compact layout, reducing the overall volume and floor space of the copper foil production equipment 100. At the same time, the power modules 610 with different extension directions are arranged in a staggered manner, avoiding dense stacking of the power modules 610, forming natural ventilation and heat dissipation channels between the power supplies, reducing heat accumulation, and ensuring long-term stable operation of the power supply. On the other hand, arranging multiple power modules 610 in multiple directions can distribute and balance the weight and electromagnetic force of the overall power supply component 60 in three-dimensional space, reducing the single The side-concentrated load reduces the eccentric torque on the support frame 30 and the elastic component 40, making the guiding and buffering mechanism more uniformly stressed and run more smoothly. At the same time, the power modules 610 can be arranged near the position of the cathode connector 51, making the cathode connector row 52 shorter and the route smoother, reducing line resistance and voltage loss, and improving current transmission efficiency and power supply stability. Furthermore, the multiple power modules 610 arranged in multiple directions and angles can realize multi-directional and multi-point power supply to the cathode roller 22, further balancing the circumferential and axial current distribution, improving electric field uniformity, and improving the consistency of copper foil thickness and surface quality.

[0059] Please refer to the following: Figure 2 , Figure 3 and Figure 5 , Figure 5 yes Figure 1The second exploded view shows the power supply connection mechanism of the copper foil production equipment. The support frame 32 includes a first frame 321, a second frame 322, and a third frame 323. The first frame 321 is horizontally connected to the support plate 31 and is equipped with a first power module 611. The first frame 321 is vertically connected to the support plate 31 and is equipped with a second power module 612. The third frame 323 is obliquely connected to the first frame 321 and the second frame 322 and is equipped with a third power module 613. Therefore, on the one hand, the first frame 321, the second frame 322, and the inclined third frame 323 together form a stable triangular or polygonal support structure, which improves the overall rigidity of the support frame 32 and makes it less prone to deformation. The support frame 32 can reliably support multiple power modules 610, improve the installation accuracy of the power supply component 60, and make full use of the height, length, and inclined space of the copper foil production equipment 100 to improve space utilization and reduce the overall volume of the copper foil production equipment 100. On the other hand, the multiple power modules 610 are arranged in zones, so that the weight and electromagnetic force of the power supply component 60 are distributed along the horizontal, vertical, and inclined directions, avoiding local load concentration, reducing the eccentric moment on the support plate 31 and the elastic component 40, and making the guide mechanism run more smoothly. At the same time, the multi-directional arrangement of the first frame 321, the second frame 322 and the third frame 323 can disperse and attenuate vibrations, reducing the transmission of the working vibration of the power supply component 60 to the guide rod 412 and the elastic component 40, avoiding poor contact and guide jamming of the power supply component 60 due to vibration, and improving the operational stability of the copper foil production equipment 100; on the other hand, the multi-directional frame creates natural gaps and ventilation channels between the power supply modules 610, making it less likely for heat to accumulate and improving heat dissipation efficiency, which can reduce the temperature rise of the power supply component 60 and the conductive connection component 50, and improve the stability of long-term operation under high current conditions; at the same time, the power supply modules 610 are arranged close to each other according to the frame orientation, which can make the cathode connection row 52 more reasonable and shorter, reduce line resistance and voltage drop, improve current transmission efficiency, and improve the stability of the current quality of the cathode roller 22.

[0060] At least one of the first frame 321, the second frame 322, and the third frame 323 is configured with a hollow structure to facilitate heat exchange between the power module 610 and the external environment. For example, the first frame 321 may include two crossbars 3211 and multiple vertical bars 3212. The multiple vertical bars 3212 are spaced apart between the two crossbars 3211 along the length Y direction of the copper foil production equipment 100.

[0061] In some alternative embodiments, the first frame 321 may further include a plurality of connecting rods 3213. The plurality of connecting rods 3213 are spaced apart between two crossbars 3211 along the length Y direction of the copper foil production equipment 100. Guide rods 412 pass through the corresponding connecting rods 3213. Thus, the connecting rods 3213 are decoupled from the longitudinal rods 3212, thereby improving the rigidity of the longitudinal rods 3212 and enhancing the load-bearing capacity of the first frame 321. The first frame 321 may further include a plurality of support rods 3214. One end of the support rod 3214 is fixedly connected to the longitudinal rod 3212 and / or the crossbar 3211, and the other end of the support rod 3214 is fixedly connected to the support rod 3214. Thus, a heat dissipation space is formed between the support plate 31 and the first frame 321, facilitating heat exchange between the power module 610 and the external environment.

[0062] The second frame 322 may include multiple vertical rods 3221 and two support rods 3222. The support rods 3222 are connected to two adjacent vertical rods 3221 and are used to support the second power module 612. The second frame 322 may also include a first connecting rod 3223 and a second connecting rod 3224. The first end of the third frame 323 is fixedly connected to the first connecting rod 3223 and the second connecting rod 3224, and the second end of the third frame 323 is connected to the first frame 321. Specifically, the first connecting rod 3223 is connected between two adjacent vertical rods 3221, and the first end of the third frame 323 is connected to the middle of the first connecting rod 3223. The first end of the second connecting rod 3224 is fixedly connected to the first frame 321, and the second end of the second connecting rod 3224 is fixedly connected to the third frame 323. The third frame 323 is configured as a rectangular frame. Therefore, the third frame 323 connects with the first frame 321 and the second frame 322 to form a triangular frame structure, thereby improving the stability and reliability of the connection between the first frame 321, the second frame 322 and the third frame 323, and enhancing the structural strength and load-bearing capacity of the supporting frame 32. It should be noted that the specific structural configuration of the supporting frame 32 can be set according to the actual situation, and the embodiments of this application do not impose specific limitations.

[0063] Please refer to it again. Figure 2 , Figure 3 and Figure 5One or more cathode connection bars 52 include at least one of a first cathode connection bar 521, a second cathode connection bar 522, and a third cathode connection bar 523. The two ends of the first cathode connection bar 521 are fixedly connected to the first power module 611 and the cathode connector 51, respectively. The two ends of the second cathode connection bar 522 are fixedly connected to the first power module 611 and the cathode connector 51, respectively. The two ends of the third cathode connection bar 523 are fixedly connected to the first power module 611 and the cathode connector 51, respectively. The first cathode connection bar 521, the second cathode connection bar 522, and the third cathode connection bar 523 are configured with an irregularly shaped bent structure. Therefore, on the one hand, the first cathode connection bar 521, the second cathode connection bar 522, and the third cathode connection bar 523 are configured as irregularly shaped copper bars, which can respectively correspond to the spatial layout of different positions and angles between the power module 610 and the cathode connector 51, effectively avoiding interference from the support frame 32 and other structures, making the conductive connection path more reasonable and improving space utilization; on the other hand, the first cathode connection bar 521, the second cathode connection bar 522, and the third cathode connection bar 523 have a certain elastic deformation capacity, which can absorb displacement and stress when the equipment vibrates or expands and contracts thermally. This design avoids loosening, cracking, or poor contact at the connection points due to tension or compression in rigid straight busbars. Furthermore, the irregularly shaped bent structure has higher rigidity and stronger resistance to lateral bending compared to straight copper busbars, making it less prone to deformation and swaying under vibration and maintaining stable conductive positions over a long period. Additionally, the simultaneous compression and connection of the first cathode connecting busbar 521, the second cathode connecting busbar 522, and the third cathode connecting busbar 523 within the same cathode busbar assembly 520 ensures more thorough and stable contact at the conductive surfaces, significantly reducing contact resistance, minimizing the risk of arcing and burning, and guaranteeing continuous and stable current transmission. For example, the first cathode connecting busbar 521 is configured as an L-shaped copper busbar, the second cathode connecting busbar 522 as a Z-shaped copper busbar, and the third cathode connecting busbar 523 as a U-shaped copper busbar. This allows for foolproof assembly of copper busbars of different shapes, reducing the probability of incorrect or reversed assembly, facilitating rapid positioning and tightening, and improving assembly efficiency and product consistency.

[0064] The cathode connector 51 includes a conductive bushing 511 and a conductive seat 512. The conductive bushing 511 is sleeved on the outside of the cathode roller 22. The conductive seat 512 is electrically connected to the conductive bushing 511. It also includes a conductive substrate 5121 and two conductive busbar connectors 5122. The two conductive busbar connectors 5122 are disposed on the side of the conductive substrate 5121 away from the conductive bushing 511 and are electrically connected to one or more cathode connectors 52. Therefore, on the one hand, the conductive bushing 511 is sleeved on the outside of the cathode roller 22, forming a large-area annular conductive contact. The current is uniformly conducted from the bushing to the entire circumference of the cathode roller 22, avoiding excessive local current caused by single-point concentrated power feeding, improving the uniformity of the electric field and the consistency of the copper foil thickness. At the same time, the conductive bushing 511 and the cathode roller 22 are sleeved together, and the conductive contact area is much larger than that of single-point or small-area contact, effectively reducing contact resistance, reducing heat generation, arcing and ablation under high current conditions, and extending service life. On the other hand, the two conductive busbar connectors 5122 are symmetrically arranged and can be connected to the symmetrically arranged cathode conductive busbar assembly 520 to realize symmetrical bidirectional power feeding on both sides, reducing potential difference and current bias, reducing voltage fluctuation, and improving power supply stability. Furthermore, the conductive substrate 5121 is fixedly connected to the two conductive busbar connectors 5122 to form an integral rigid structure, which is not easily deformed or loosened under the vibration of the copper foil production equipment 100 and the action of high current electromagnetic force, improving the long-term conductivity reliability of the conductive connection component 50.

[0065] For example, in this embodiment, the number of cathode connectors 51 in the same conductive connection component 50 can also be set to two, that is, the conductive connection component 50 includes two cathode connectors 51. The two cathode connectors 51 are spaced apart along the axial direction of the cathode roller 22 (i.e., the width direction X of the copper foil production equipment 100). The number of cathode conductive bus assemblies 520 can also be set to four. Each cathode connector 51 is fixedly connected to the first cathode connecting bus 521, the second cathode connecting bus 522, and the third cathode connecting bus 523 in the two cathode conductive bus assemblies 520. Specifically, two of the four cathode conductive bus assemblies 520 are defined as the first cathode conductive bus assembly, and the other two of the four cathode conductive bus assemblies 520 are defined as the second cathode conductive bus assembly. The two cathode connectors 51 are electrically connected to the first cathode conductive bus assembly and the second cathode conductive bus assembly, respectively. Therefore, on the one hand, two cathode connectors 51 arranged axially at intervals are provided at the same end of the cathode roller 22, which, together with the first cathode conductive bus assembly and the second cathode conductive bus assembly, conduct electricity separately, realizing single-end multi-point power supply, making the current distribution axially more uniform at the end of the cathode roller 22, avoiding local current concentration caused by single-point power supply, and improving the overall electric field uniformity of the roller surface; at the same time, the two cathode connectors 51 are arranged axially separately at the same end, which can supply power to different axial positions of the cathode roller 22 respectively, better compensating for the axial current attenuation of the wide cathode roller 22, and improving the uniformity of the copper foil thickness across the entire width; on the other hand, the first cathode conductive bus assembly and The second cathode busbar assembly is connected to two cathode connectors 51 respectively, forming independent conductive paths. This reduces electromagnetic interference and potential differences between currents, improving current transmission quality. Furthermore, the symmetrical or spaced arrangement of the dual connectors and dual copper busbars at the same end results in more balanced stress, effectively resisting equipment vibration and electromagnetic shocks, preventing loose connections and poor contact, and ensuring long-term reliable operation. Additionally, the two cathode connectors 51 are axially separated at the same end, allowing them to supply power to different axial positions of the cathode roller 22, better compensating for axial current attenuation in the wide-width cathode roller 22 and improving the overall thickness consistency of the copper foil. Of course, in some embodiments, the number of cathode connectors 51 can be set to one, and the number of cathode busbar assemblies 520 can be set to two.
