It is used to clamp a film during film electroplating, and includes a conductive upper clamp and a conductive lower clamp. It is characterized in that, at the clamping mouth, one side of the conductive upper clamp is a conductive first boss and the other side is a flexible soft glue, and one side of the conductive lower clamp is a conductive second boss and the other side is a flexible soft glue.

Description

Technical Field

[0001] The utility model relates to the technical field of thin film electroplating equipment, in particular to a single-sided conductive conductive clip which can prevent thin film from tearing. Background Art

[0002] Thin film plating is a surface treatment technology that coats a thin layer of metal or alloy on the surface of a thin film material to improve the surface performance, aesthetics or durability of the material. As an important surface treatment technology, it has been widely used in various fields. The application range of thin film plating is very wide, including automobiles, home appliances, construction, electronics and other fields.

[0003] For example, in battery technology, composite current collector film is a new type of current collector material, mainly used in lithium-ion batteries, which plays a role in improving safety, energy density, and service life of lithium batteries. It has a "sandwich structure" with copper and aluminum layers plated on both sides of the base film to form a composite aluminum film or a composite copper film, in which the base film is usually a PET or PP film.

[0004] For composite current collector membranes, when the metal film layer is electroplated on both sides of the base membrane, a conductive clamp is required to clamp the edge of the base membrane. Since the base membrane is very thin, during the electroplating process on the surface of the film, the position where the film is clamped by the conductive clamp is easily scratched by the clamping edge of the conductive clamp. If the conductive clamp penetrates the film, the base membrane will be easily torn during electroplating, resulting in the problem of base membrane breakage, making the electroplating impossible. In the design of the conductive clamp, it is necessary to consider changing the clamping force of the conductive clamp for different base membrane materials to prevent damage to the base membrane. For example, in the Chinese utility model patent "A conductive clamp and electroplating device with uniform opening and closing" with publication number CN220265913U, a clamping force adjustment mechanism is provided on the conductive clamp so that the conductive clamp can stably clamp the film without damaging the film and ensure the quality of electroplating. The clamping force adjustment mechanism makes the structure of the conductive clamp more complicated, and the clamping force adjustment operation is troublesome.

[0005] The above problems need to be solved urgently. Utility Model Content

[0006] In order to overcome the disadvantage of the prior art that the clamping force of the conductive clamp needs to be adjusted for different base film materials, the utility model provides a single-sided conductive clamp that prevents film tearing.

[0007] The technical solution of the utility model is as follows:

[0008] A single-sided conductive conductive clip that prevents film tearing is used to clamp the film during film electroplating, and includes a conductive upper clip and a conductive lower clip. At the clamping mouth, one side of the conductive upper clip is a conductive first boss and the other side is a flexible soft glue. One side of the conductive lower clip is a conductive second boss and the other side is a flexible soft glue. The first boss and the second boss are staggered so that when the conductive clamp is clamped, the first boss and the second boss respectively clamp the film with the soft glue on the opposite side.

[0009] Furthermore, in one embodiment, the contact surfaces of the conductive lower clamp and the conductive upper clamp are arc-shaped surfaces, and the top surfaces of the first boss and the second boss are both arc-shaped surfaces.

[0010] Furthermore, in one embodiment, the conductive upper clip includes an upper clip body and a first soft rubber sleeve, the conductive lower clip includes a lower clip body and a second soft rubber sleeve, the first soft rubber sleeve is sleeved on the upper clip body, the second soft rubber sleeve is sleeved on the lower clip body, the top surface of the first boss and the first soft rubber sleeve share an arc surface, and the top surface of the second boss and the second soft rubber sleeve share an arc surface.

[0011] Furthermore, in one embodiment, in the horizontal section of the conductive clip, the first boss is located at the side of the upper clip body, and the outer side surface of the first boss is flush with the side surface of the upper clip body; the second boss is located at the side of the lower clip body, and the outer side surface of the second boss is flush with the side surface of the lower clip body.

[0012] Furthermore, in one embodiment, a first blind hole is provided on the side surface of the first boss, and the first blind hole is filled with the soft rubber of the first soft rubber sleeve;

[0013] And / or, the second boss is provided with a second blind hole, and the second blind hole is filled with the soft rubber of the second soft rubber sleeve.

[0014] Furthermore, in one embodiment, the conductive upper clip is provided with a first through hole in a vertical direction, and the first through hole is filled with the soft rubber of the first soft rubber sleeve;

[0015] And / or, the conductive lower clip is provided with a second through hole in a vertical direction, and the second through hole is filled with the soft rubber of the second soft rubber sleeve.

[0016] Furthermore, in one embodiment, the first through hole is located on the conductive upper clip near the first boss, and the second through hole is located on the conductive lower clip near the second boss.

[0017] Furthermore, in one embodiment, the widths of the conductive upper clip and the conductive lower clip are consistent.

[0018] Further, in one embodiment, the width of the first boss is less than half of the width of the upper clamp body, and the width of the second boss is less than half of the width of the lower clamp body.

[0019] Furthermore, in one embodiment, the intersection of the top surface and the side surface of the first boss is an arc surface, and the intersection of the top surface and the side surface of the second boss is an arc surface.

[0020] The utility model according to the above scheme has the beneficial effect that the conductive upper clamp and the conductive lower clamp of the conductive clamp adopt a half-side conductive method to change the structure of the clamped electroplated film. When the electroplated film is clamped by the conductive clamp, one side of the electroplated film contacts the conductive metal boss and the other side contacts the soft rubber sleeve. The clamping position of the film is squeezed by the boss, and the two side surfaces of the film are close to the boss and the soft rubber. Since the soft rubber is flexible and can produce elastic deformation, the metal surface is not easy to scratch the electroplated film when clamped and fixed, so that the clamping force between the conductive upper clamp and the conductive lower clamp can be applied to base films of various materials or thicknesses. Therefore, there is no need to adjust the clamping force between the conductive upper clamp and the conductive lower clamp for different base film materials, which solves the problem of needing to adjust the clamping force for different base film materials, simplifies the conductive clamp structure, reduces the adjustment steps of the electroplating operation, and reduces the time-consuming adjustment of production equipment.

[0028] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] The present application provides a single-sided conductive conductive clamp that prevents film tearing, which is used to clamp the film during film electroplating, and includes a conductive upper clamp and a conductive lower clamp. At the clamping opening, one side of the conductive upper clamp is a conductive first boss and the other side is a flexible soft glue, and one side of the conductive lower clamp is a conductive second boss and the other side is a flexible soft glue. The first boss and the second boss are staggered so that when the conductive clamp is clamped, the first boss and the second boss clamp the film with the soft glue on the opposite side respectively. When the electroplated film is clamped by the conductive clamp, one side of the electroplated film contacts the metal boss and the other side contacts the soft glue sleeve. The top surfaces of the first and second bosses are exposed and conductive to ensure ionization of the surface of the electroplated film; one side of the electroplated film contacts the metal boss and the other side contacts the soft rubber sleeve. The clamping position of the film is squeezed by the boss, and the surfaces on both sides of the film are close to the boss and the soft rubber. Since the soft rubber is flexible and can produce elastic deformation, the metal surface is not easy to scratch the electroplated film when clamped and fixed, making the contact between the electroplated film and the first and second bosses closer, preventing the electroplated film from tearing when being tightened, and solving the problem of film breakage caused by being clamped through. The unilateral conductive structural design increases the range of base films that can be applied to the clamping force formed when the conductive upper clamp and the conductive lower clamp of the utility model are clamped, and there is no need to adjust the clamping force of the conductive upper clamp and the conductive lower clamp when clamping for different base film materials.

[0030] like Figure 1-Figure 3As shown, the present application provides an embodiment of a unilateral conductive conductive clip that prevents film tearing. The present embodiment is used to clamp the film during film electroplating, and includes a conductive upper clip 100 and a conductive lower clip 200. The conductive upper clip 100 includes an upper clip body 110 and a first soft rubber sleeve 120 sleeved outside the upper clip body 110, and the conductive lower clip 200 includes a lower clip body 210 and a second soft rubber sleeve 220 sleeved outside the lower clip body 210; on the clamping surface of the conductive clip, the upper clip body 110 has a first boss 1101, and the lower clip body 210 has a second boss 2101. The first boss 1101 and the second boss 2101 are staggered so that when the conductive clip is clamped, the first boss 1101 and the second boss 2101 clamp the film with the soft rubber on the opposite side. The first soft rubber sleeve 120 and the second soft rubber sleeve 220 are insulating materials and are flexible. The upper clip body 110 and the lower clip body 210 are made of the same metal, generally made of stainless steel. When the conductive clamp is clamped, the first boss 1101 and the soft rubber of the second soft rubber sleeve 220 on the conductive lower clamp 200 abut against and clamp the film placed in the middle of the two, and the second boss 2101 and the soft rubber of the first soft rubber sleeve 120 on the conductive upper clamp 100 abut against and clamp the film placed in the middle of the two. The conductive clamp body of the present application adopts a half-edge conductive method to change the structure of the conductive upper clamp 100 and the lower clamp clamping the electroplated film. When the electroplated film is clamped by the conductive clamp, one side of the electroplated film contacts the metal boss and the other side contacts the soft rubber sleeve. The top surfaces of the first boss 1101 and the second boss 2101 are exposed and conductive to ensure ionization of the surface of the electroplated film; one side of the electroplated film contacts the metal boss and the other side contacts the soft rubber sleeve. The clamping position of the film is squeezed by the boss. Since the soft rubber is flexible and can produce elastic deformation, the two sides of the film are close to the boss and the soft rubber. When clamped, the metal surface is not easy to scratch the electroplated film, so that the clamping force between the conductive upper clamp 100 and the conductive lower clamp 200 can be applied to a variety of base films of different materials or thicknesses. Therefore, there is no need to adjust the clamping force between the conductive upper clamp 100 and the conductive lower clamp 200 for different base film materials, which solves the problem of adjusting the clamping force for different base film materials, simplifies the conductive clamp structure, reduces the adjustment steps of the electroplating operation, and reduces the time-consuming adjustment of the production equipment. When clamped, the electroplated film is in closer contact with the first boss 1101 and the second boss 2101.

[0031] In this embodiment, the first soft rubber sleeve 120 and the second soft rubber sleeve 220 are made of insulating materials, so that the conductive upper clip 100 and the conductive lower clip 200 are exposed only at the first boss 1101 and the second boss 2101 in the contact part with the film, ensuring good conductivity. The first soft rubber sleeve 120 and the second soft rubber sleeve 220 reduce the exposed position, reduce the deposition of the coating on the conductive clip, reduce the cleaning frequency, and reduce material waste. Generally, the first soft rubber sleeve 120 and the second soft rubber sleeve 220 are made of silicone.

[0032] In order to facilitate the clamping of the film, the upper clamp body 110 and the lower clamp body 210 of the conductive clamp both have a bent horizontal section, the horizontal section forms the clamping opening of the conductive clamp, the bending position of the upper clamp body 110 has a greater bending degree, and the first soft rubber sleeve 120 is divided into two parts, one part is connected to wrap the horizontal section and the bending section of the upper clamp body 110, and the other part is connected to the bending section to wrap the vertical section of the conductive upper clamp 100 to protect the part of the conductive upper clamp 100 immersed in the electroplating solution. The first soft rubber sleeve 120 is insulated to reduce the formation of the deposited coating on the conductive clamp. The first soft rubber sleeve 120 is connected in sections, which is convenient for the connection of the first soft rubber sleeve 120, the assembly of the conductive clamp, and the subsequent production.

[0033] like Figure 4 and Figure 5 As shown, in one embodiment, the top surface of the first boss 1101 and the top surface of the second boss 2101 are both arc surfaces, and the contact surface of the conductive lower clamp 200 and the conductive upper clamp 100 is an arc surface. When the two arc surfaces are in contact, they can be automatically aligned, so that the film can be better clamped.

[0034] Figure 5 As shown, in one embodiment, the top surface of the first boss 1101 and the contact surface of the first soft rubber sleeve 120 share an arc surface, and the top surface of the second boss 2101 and the contact surface of the second soft rubber sleeve 220 share an arc surface. The first boss 1101 and the second boss 2101 share an arc surface with their respective soft rubber sleeves, the first soft rubber sleeve 120 and the second soft rubber sleeve 220, respectively, so that when the electroplated film is clamped, the contact surface of the electroplated film and the conductive upper clamp 100 is the same arc surface, and the contact surface of the electroplated film and the conductive lower clamp 200 is the same arc surface. The arc surfaces of the conductive upper clamp 100 and the conductive lower clamp 200 can be embedded, so that the electroplated film is in close contact with the conductive upper clamp 100 and the conductive lower clamp 200, so that the film is firmly fixed and not easy to tear.

[0035] like Figure 2 and Figure 3 As shown, in one embodiment, in the horizontal section of the conductive clip, the first boss 1101 is located on one side of the upper clip body 110, and the outer side of the first boss 1101 is flush with the side of the upper clip body 110; the second boss 2101 is located on one side of the lower clip body 210, and the outer side of the second boss 2101 is flush with the side of the lower clip body 210. It is beneficial to balance the forces on both sides of the film on the clip body. It is convenient to determine the position of the boss. In this embodiment, the first boss 1101 is located on the left side of the upper clip body 110, and the second boss 2101 is located on the right side of the lower clip body 210, and they are relatively staggered.

[0036] like Figure 5As shown, in one embodiment, the width of the conductive upper clip 100 is the same as the width of the conductive upper clip 100. The conductive upper clips 100 are aligned with the conductive upper clips 100 without misalignment space, thereby preventing the film from being torn at the side due to force.

[0037] like Figure 5 As shown, in one embodiment, the width of the first boss 1101 is less than half of the width of the upper clamp body 110, and the width of the second boss 2101 is less than half of the width of the lower clamp body 210. This design makes the top surfaces of the first boss 1101 and the second boss 2101 non-contact, so as to prevent both sides of the film from contacting with the metal to form a clamp, and to prevent the metal boss from scratching the surface of the film, resulting in tearing of the film.

[0038] like Figure 3 As shown, in one embodiment, a first blind hole 300 is provided on the side of the first boss 1101, and a second blind hole 500 is provided on the second boss 2101. The first blind hole 300 and the second blind hole 500 are filled with soft rubber, so that the first soft rubber sleeve 120 is fixed on the first boss 1101, and the second soft rubber sleeve 220 is fixed on the second boss 2101. There are two first blind holes 300 on the first boss 1101, and the two first blind holes 300 are connected. The blind holes allow the soft rubber of the first soft rubber sleeve 120 to extend into the first boss 1101, so that the connection between the first soft rubber sleeve 120 and the first boss 1101 is tighter and firmer. When the conductive clip is clamped, the soft rubber at the position of the first soft rubber sleeve 120 wrapped around the first boss 1101 is not easy to slide relative to the first boss 1101, thereby ensuring the stability of the film clamping. Similarly, there are two first blind holes 300 on the second boss 2101, and the two second blind holes 500 are connected. The blind holes allow the soft rubber of the second soft rubber sleeve 220 to extend into the second boss 2101, making the connection between the second soft rubber sleeve 220 and the second boss 2101 tighter and more secure. When the conductive clip is clamped, the soft rubber of the second soft rubber sleeve 220 wrapped around the second boss 2101 is not easy to slide relative to the second boss 2101, ensuring the stability of the film clamping. In summary, the provision of the first blind hole 300 and the second blind hole 500 helps to improve the stability of the film clamping.

[0039] like Figure 3As shown, in one embodiment, the conductive upper clip 100 is provided with a plurality of first through holes 400 near the first boss 1101, and the conductive lower clip 200 is provided with a plurality of second through holes 600 near the second boss 2101, and the first through holes 400 and the second through holes 600 are filled with soft glue. At the clamping position, the first through holes 400 allow the soft glue of the first soft rubber sleeve 120 to extend into the upper clip body 110, so that the first soft rubber sleeve 120 is more firmly fixed on the upper clip body 110, and the second through holes 600 allow the soft glue of the second soft rubber sleeve 220 to extend into the lower clip body 210, so that the second soft rubber sleeve 220 is more firmly fixed on the lower clip body 210, so that the film is fixed more firmly.

[0040] In one embodiment, in a single-sided conductive conductive clip that prevents film tearing, in which the widths of the conductive upper clip 100 and the conductive lower clip 200 are the same, the widths of the first boss 1101 and the second boss 2101 are the same. The widths of the first boss 1101 and the second boss 2101 are the same, so that the film has the same clamping arc length on both sides, so that the forces on both sides of the film are balanced, and the film is stably clamped in the conductive clip.

[0041] In one embodiment, the top surface and the side surface of the first boss 1101 are connected by an arc surface, and the top surface and the side surface of the second boss 2101 are connected by an arc surface. The intersection of the surfaces of the first boss 1101 and the second boss 2101 is designed to be a smooth arc surface, which is convenient for the sleeve connection between the upper clamp body 110 and the first soft rubber sleeve 120, and convenient for the sleeve connection between the lower clamp body 210 and the second soft rubber sleeve 220. It is convenient to assemble and use the device and reduce the damage of the soft rubber sleeve by the edges.

[0042] In one embodiment, the intersection of the clamping surface and the side surface of the first soft rubber sleeve 120 is an arc surface, and the intersection of the clamping surface and the side surface of the second soft rubber sleeve 220 is also an arc surface. The arc surface is smooth and forms a surface contact with the film. During the process of tightening or relaxing the film, the film and the soft rubber sleeve form a surface contact, which can prevent the edge from damaging the film and causing it to break.

[0043] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.

[0044] The above is an exemplary description of the utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the utility model patent is not limited to the above-mentioned method. As long as various improvements are made by adopting the method concept and technical solution of the utility model patent, or the concept and technical solution of the utility model patent are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
