[0002] Horizontal electroplating is an electroplating method in which the workpiece to be plated is placed parallel to the surface of the electroplating solution. It is characterized by its ease of operation, wide applicability to a wide range of workpiece sizes, and suitability for large-scale automated operations and enclosed environments, and has experienced rapid development in recent years. In the field of solar cell manufacturing, electroplating processes are involved, such as the metallization process, which utilizes techniques like horizontal electroplating. In recent years, with the optimization and upgrading of solar cell manufacturing processes, it is often necessary to perform surface electroplating on the coated solar cells through cathode and anode components. Optimizing the cathode conductivity has become a pressing issue.

[0003] In related technologies, during the metallization process of solar cells, for horizontal plating, some cathode conduction methods use rollers or conductive rollers for conductivity, which is convenient and can avoid damage to the coating on the cell surface. Typically, roller brushes are installed on the conductive rollers to allow for flexible contact between the brushes and the workpiece to be plated, preventing damage. However, the existing installation structure or arrangement of the roller brushes on conductive rollers still has certain shortcomings, failing to achieve sufficient and effective contact with the workpiece, which can easily affect the uniformity of the coating.

[0017] In some embodiments, the sidewall of the roller is provided with a plurality of fixing grooves, the plurality of fixing grooves are arranged at intervals along the circumference of the roller body, and each fixing groove extends along the axial direction of the roller body; the fixing grooves and the mounting grooves are connected through the through holes; the two ends of the conductive element are correspondingly disposed in the fixing grooves so that the cylinder cavity of the roller is isolated from the roller brush to form a seal.

[0018] In some embodiments, a seal is provided between the surface of the insulating structure facing the bottom wall of the mounting groove and the bottom wall of the mounting groove.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] In related technologies, unevenness in the plating layer (film) on the workpiece during electroplating still exists. Various factors are involved in improving this unevenness, such as the shape of the anode, the distance between the anode and cathode, and the cathode structure or polarization. Optimizing the anode structure and shape to improve the unevenness of the electroplated layer is a common practice in the industry. However, to achieve better electroplating results, improving the cathode is also crucial, provided the anode is stabilized. Therefore, this application mainly provides a cathode conductive brush arrangement scheme that can be used to improve the uniformity of the plating layer on the product being plated.

[0045] In some embodiments, a conductive roller is provided, which can be applied in the field of electroplating, such as in horizontal electroplating equipment, to achieve conductivity, such as to achieve cathode conductivity. In addition, it can also be used in other equipment. The embodiments of this application do not impose specific limitations on the specific application scenarios and working conditions of the conductive roller.

[0046] Please see Figures 1 to 12 As shown, in some embodiments of this application, a conductive roller is provided. The conductive roller can rotate under the drive of a driving mechanism and can be used to make contact with the workpiece to be plated and conduct electricity. The conductive roller includes: a roller body 10 and a plurality of roller brushes 20; the outer wall of the roller body 10 is provided with a plurality of sets of mounting grooves 111, the plurality of sets of mounting grooves 111 are arranged along the circumference of the roller body 10, and the mounting grooves 111 in each set are arranged along the axial direction of the roller body 10; each roller brush 20 is correspondingly disposed in the mounting groove 111, one end of the roller brush 20 protruding from the outer wall of the roller body 10; the bottom of the mounting groove 111 is provided with a through hole 112, and the other end of the roller brush 20 passes through the mounting groove 111 and is connected to the roller body 10 through the through hole 112.

[0047] The number of mounting grooves 111 can correspond to the number of roller brushes 20, with multiple roller brushes 20 being disposed in multiple mounting grooves 111 in a one-to-one correspondence. Optionally, in order to improve the sealing between the roller brushes 20 and the mounting grooves 111, a sealing material can be provided between each roller brush 20 and at least a portion of the groove wall of the corresponding mounting groove 111, for example, adding insulating sealant between the roller brushes 20 and the groove after installation in the mounting groove 111; thus, the sealing performance can be improved.

[0048] To facilitate the installation and connection of the roller brush 20 and improve the reliability and stability of its installation or connection, a through hole 112 is provided on the bottom wall of the mounting groove 111. That is, the mounting groove 111 and the through hole 112 are interconnected on the side wall of the roller body 10. Optionally, depending on the structural characteristics of the roller brush 20, the mounting groove 111 and the through hole 112 can be arranged in a stepped manner; for example, the diameter of the mounting groove 111 is larger than the diameter of the through hole 112. One end of the roller brush 20 protrudes from the outer wall of the roller 11, and the other end of the roller brush 20 passes through the through hole 112 and connects to the roller body 10, such as connecting to the conductive element 12 in the roller body 10. A portion of the roller brush 20 can be set in the mounting groove 111, and a portion can be set in the through hole 112. At least a portion of the roller brush 20 set in the through hole 112 can be connected to the conductive element 12 in the roller body 10.

[0049] Thus, by setting through holes 112 at the bottom of the mounting groove 111, it can be adapted to the structural shape of the roller brush 20, making it easier to install and connect the roller brush 20, improving the stability and reliability of the roller brush 20 installation and connection, thereby ensuring effective contact between the roller brush 20 and the workpiece to be plated, and facilitating the connection between the roller brush 20 and the conductive component 12 in the conductive roller. The reasonable structural design helps to ensure the reliability of the roller brush 20 installation and connection, thereby ensuring the quality of the coating.

[0050] The aforementioned multiple sets of mounting grooves 111 are arranged circumferentially along the roller body 10, and the mounting grooves 111 in each set are arranged axially along the roller body 10. The distribution of the mounting grooves 111 also determines the distribution of the roller brushes 20. For example, multiple roller brushes 20 can be divided into multiple sets of roller brushes 20, and the multiple sets of roller brushes 20 can be arranged circumferentially along the roller 11, and the roller brushes 20 in each set are arranged axially along the roller 11. This arrangement of the roller brushes 20 helps to ensure that the roller brushes 20 fully contact the workpiece to be plated, thereby improving the quality of the plating layer.

[0051] Typically, with the anode titanium mesh and current / voltage parameters fixed, the roller brush 20 (such as a conductive roller brush) on the workpiece affects the uniformity of electroplating. The roller brush 20 on the conductive roller appears in the form of a brush, and its structure is equivalent to making the roller brush 20 on the conductive roller smaller, which improves its flexibility. When arranging the roller brush 20, it is important to ensure that at least one roller brush 20 appears on each longitudinal section. This ensures that every part of the workpiece, such as each tank section, is brushed during the electroplating process, guaranteeing uniformity and improving the uniformity of the plating layer.

[0052] In this embodiment, the arrangement of the multiple roller brushes 20 can take many forms, such as the following three listed below.

[0053] like Figures 4 to 6 As shown, in some embodiments, the roller brushes 20 in two adjacent sets of mounting slots 111 are aligned and arranged in the circumferential direction and axial direction of the roller body 10, respectively. This arrangement of the roller brushes 20 is a straight, non-intersecting type, and the roller brushes 20 generally cover the surface area of ​​the workpiece to be plated. However, there is still room for improvement in terms of improving the uniformity of the coating on the workpiece.

[0054] like Figures 7 to 9 As shown, in some other embodiments, the roller brushes 20 in two adjacent sets of mounting grooves 111 are staggered in the axial direction of the roller body 10. This arrangement of the roller brushes 20 is a pairwise staggered type, which is better for covering the surface area of ​​the workpiece to be plated.

[0055] Compared to the linear, non-intersecting distribution of the roller brushes 20 described above, considering that during the electroplating process, the workpiece to be plated (preferably a silicon wafer in this application) will move to a certain position on the horizontal plane in a direction perpendicular to the direction of movement, by arranging the roller brushes 20 on the roller body 10 in a staggered manner, it helps to ensure that at least one roller brush 20 appears on each longitudinal section. Thus, during the electroplating process, every part of the workpiece to be plated, such as each tank part, will be brushed through, ensuring the uniformity of the electroplating process, thereby improving the uniformity of the coating and improving the coating quality.

[0056] like Figures 10 to 12As shown, in some embodiments, multiple roller brushes 20 are arranged in a spiral staggered pattern on the outer wall of the roller body 10. This arrangement of roller brushes 20 is a staggered spiral type, and the roller brushes 20 optimally cover the surface area of ​​the workpiece to be plated. Therefore, by adopting a spiral staggered arrangement, the coverage area of ​​the roller brushes 20 can be further expanded, and it can be further ensured that at least one roller brush 20 appears on each longitudinal section. Thus, during the electroplating process, every part of the workpiece to be plated, such as each tank part, will be brushed. Since the thickness uniformity of the entire workpiece to be plated will vary with the coverage area of ​​the roller brushes 20, the uniformity of the electroplating process can be further ensured, the uniformity of the coating can be further improved, and the coating quality can be improved.

[0057] In summary Figures 4 to 12 It can be seen that the preferred arrangement of the roller brushes 20 in this embodiment is either a spiral staggered arrangement or a pairwise staggered arrangement. The area of ​​the workpiece surface covered by the roller brushes 20 increases sequentially from a straight, non-staggered arrangement to a pairwise staggered arrangement to a spiral staggered arrangement. The coating thickness in the covered area of ​​the roller brushes 20 is higher than that in the uncovered area. Therefore, the uniformity of the coating thickness of the entire workpiece will also gradually change as the area covered by the roller brushes 20 increases. Thus, by using a spiral staggered arrangement of the roller brushes 20, the uniformity of the coating on the workpiece to be coated will be better.

[0058] In some embodiments, the roller body 10 includes a roller 11 and a conductive element 12, the conductive element 12 being disposed in the cavity of the roller 11; the other end of the roller brush 20 passes through the through hole 112 and is mechanically and electrically connected to the conductive element 12. One end of the roller brush 20 protrudes from the outer wall of the roller 11 at its upper end, and the other end of the roller brush 20 passes through the through hole 112 at its lower end and is connected to the conductive element 12; a portion of the roller brush 20 may be disposed in the mounting groove 111, and a portion may be disposed in the through hole 112, with at least a portion of the roller brush 20 disposed in the through hole 112 being connected to the conductive element 12.

[0059] Optionally, the conductive roller may further include a conductive component and an electrode component. The conductive component can be electrically connected to both the conductive roller and the electrode component. For example, the conductive component can be electrically connected to the conductive element 12 in the conductive roller, serving as an intermediate conductor of electrical energy. The electrode component can be electrically connected to an external power source. The electrode component can be electrically connected to the conductive roller through the conductive component. By connecting the electrode component to the external power source, electrical energy is conducted to the conductive component, and then conducted to the conductive roller. The conductive roller then contacts the workpiece to be plated, thereby applying the conducted electricity, especially the negative electrode electricity, to the workpiece.

[0060] It should be noted that this embodiment does not limit the specific structural form of the conductive component and the electrode component, and can refer to relevant prior art, which will not be elaborated here.

[0061] Optionally, a sealing material such as insulating adhesive can be placed inside the roller 11 of the conductive roller to ensure internal insulation and sealing, reduce or prevent liquid from entering and causing internal short circuits and corrosion.

[0062] In this embodiment, a sealing material can be provided between each roller brush 20 and the roller 11 in the cylinder cavity of the roller 11. For example, insulating sealant can be used as the sealing material. This can prevent liquid from entering the inside of the roller 11, ensuring the sealing and insulation of the inside of the roller 11. This avoids internal short circuits and corrosion caused by liquid entering the inside of the roller 11. It can also reduce or avoid corrosion or conduction of the internal conductive parts 12 caused by liquid entering between the roller brush 20 and the roller 11. Thus, the sealing performance of the conductive roller is improved, the occurrence of short circuits or corrosion is reduced, and the service life of the conductive roller is extended, ensuring the coating effect and efficiency.

[0063] Furthermore, in addition to the sealing method using the aforementioned sealing insulating adhesive, other different sealing methods can be used, such as sealing rings or sealing rings. By using sealing rings or sealing rings, the sealing performance of the conductive roller can be ensured, while also improving its replaceability. Individual damaged or repairable roller brushes 20 can be replaced without replacing the entire conductive roller, thereby improving the overall replaceability and maintainability of the conductive roller and helping to reduce maintenance costs.

[0064] In some embodiments, the roller brush 20 includes a brush structure 21, an insulating structure 22, and a conductive structure 23; the brush structure 21 is mechanically and electrically connected to the conductive element 12 via the conductive structure 23; the insulating structure 22 is disposed on the outside of the brush structure 21, and at least a portion of the insulating structure 22 is embedded in the mounting groove 111. At least a portion of the brush structure 21 protrudes from the outer wall of the roller 11 for contacting the workpiece to be plated, and the brush structure 21 is mechanically and electrically connected to the conductive element 12 via the conductive structure 23; the insulating structure 22, such as an insulating sleeve, may be disposed on the outside of the brush structure 21, and at least a portion of the insulating sleeve is embedded in the mounting groove 111.

[0065] In this embodiment, by providing an insulating structure 22 on the outside of the brush structure 21, an insulating effect can be achieved, forming a structure that is insulated from the outside, thus avoiding or reducing excessive current consumption and copper plating.

[0066] Optionally, after the brush structure 21 and the conductive structure 23 are connected by a certain process technology, they can be injection molded to form an external insulating part, that is, to form an insulating structure 22 such as an insulating sleeve, so as to avoid or reduce excessive current consumption and copper plating.

[0067] In some embodiments, one end of the roller brush 20 is threadedly connected to the conductive element 12. For example, the conductive element 12 is provided with a threaded hole 121, and the conductive structure 23 is threadedly engaged with the threaded hole 121. One end of the roller brush 20, that is, the conductive structure 23 of the roller brush 20, can be threadedly engaged with the threaded hole 121 of the conductive element 12. Thus, the threaded connection method has a simple structure, stable and reliable connection, and is convenient for processing and manufacturing.

[0068] In some embodiments, the roller brush 20 is made of a flexible conductive material, including metal fibers or carbon fibers. That is, the brush structure 21 in the roller brush 20 is made of a flexible conductive material, including metal fibers or carbon fibers.

[0069] By distributing a certain number of roller brushes 20 on the roller 11 of the conductive roller, and the brush structure 21 of the roller brushes 20 being made of a flexible conductive material, such as a flexible material that can recover its original state after being subjected to force and is highly conductive and resistant to electroplating chemicals corrosion, for example, it can be metal fiber, carbon fiber, or other materials with similar properties. This allows the brush structure 21 to make flexible contact with the workpiece to be plated, reducing or avoiding damage to the workpiece.

[0070] In some embodiments, a seal 30 is provided between the surface of the insulating structure 22 facing the bottom wall of the mounting groove 111 and the bottom wall of the mounting groove 111. Optionally, the seal 30 can be a sealing ring, such as a sealing ring made of a flexible material.

[0071] The surface of the insulating structure 22 in the roller brush 20 facing the bottom wall of the mounting groove 111, and at least one of the bottom wall of the mounting groove 111, may be provided with an annular groove; the sealing element 30, such as a sealing ring, is disposed in the annular groove. By disposing the sealing element 30 in the annular groove, a seal can be formed between the mounting groove 111 and the roller brush 20.

[0072] To facilitate the installation of the sealing ring and ensure a good sealing effect, an annular groove can be provided in at least one of the roller brush 20 or the mounting groove 111. For example, an annular groove can be provided on the surface of the insulating structure 22 in the roller brush 20 facing the bottom wall of the mounting groove 111, and the sealing ring can be installed in this annular groove; or an annular groove can be provided in the bottom wall of the mounting groove 111, and the sealing ring can be installed in this annular groove; or annular grooves can be provided on both the surface of the insulating structure 22 in the roller brush 20 facing the bottom wall of the mounting groove 111 and the bottom wall of the mounting groove 111, and the sealing ring can be installed in this annular groove. This ensures a secure sealing connection between the roller brush 20 and the mounting groove 111, improving the sealing effect.

[0073] In some embodiments, the sidewall of the roller 11 is provided with a plurality of fixing grooves 113, the plurality of fixing grooves 113 are arranged at intervals along the circumference of the roller body 10, and each fixing groove 113 extends along the axial direction of the roller body 10; the fixing grooves 113 and the mounting grooves 111 are connected through through holes 112; the conductive element 12 is correspondingly disposed in the fixing grooves 113.

[0074] In this embodiment, a plurality of fixing grooves 113 are provided on the side wall of the roller 11. The number of fixing grooves 113 can correspond to the number of conductive elements 12 and can be used to install and fix the conductive elements 12. For example, multiple conductive elements 12 are respectively arranged in the corresponding fixing grooves 113. In order to cooperate with the setting of conductive elements 12 or roller brush 20, the multiple fixing grooves 113 are arranged at intervals along the circumference of the roller 11, and each fixing groove 113 extends along the axial direction of the roller 11.

[0075] The aforementioned fixing groove 113, also known as a limiting groove, not only serves to install the conductive component 12 but also to limit its movement. The fixing groove 113 separates adjacent conductive components 12 and accurately positions them. The fixing groove 113 can be located at the side end of the through hole 112, allowing it to connect with the mounting groove 111.

[0076] Therefore, by setting the sealing element 30, the sealing performance can be guaranteed while improving the replaceability of the conductive roller. When a single roller brush 20 is damaged or needs repair, it can be replaced individually without replacing the entire conductive roller, which helps to reduce maintenance costs and greatly improves the convenience of maintenance.

[0077] In some embodiments, the sidewall of the roller 11 is provided with a plurality of fixing holes 114, and fasteners 40 are respectively installed in the plurality of fixing holes 114, and the fasteners 40 are fastened to the conductive component 12.

[0078] In this embodiment, the conductive element 12 is disposed inside the cavity of the roller 11, and the conductive element 12 is fastened to the roller 11 by a fastener 40. Optionally, the fastener 40 can be a screw. Of course, other types of fasteners 40 can also be used, and this embodiment does not limit this.

[0079] By setting multiple fasteners 40, such as multiple screws, in the conductive roller, the conductive component 12 can be firmly and reliably connected to the roller 11, which improves the connection reliability of the conductive component 12 and helps to ensure the conductive connection effect.

[0080] Therefore, in this case, the gap between the roller brush 20 and the mounting groove 111 of the roller 11 is sealed by using insulating sealant. In this solution, the conductive component 12 can connect and fix all the roller brushes 20 from inside the roller 11. After the insulating sealant is injected into the roller 11, the roller brushes 20 are also fixed to the insulating sealant, thus making the entire conductive roller a single unit. If the roller brushes 20 are damaged or need to be replaced during subsequent use, they can be removed and replaced externally using professional tools.
