Embodiments for Carrying out the Invention

[0014] Hereinafter, the present invention will be described with reference to the drawings and examples.

[0015] Hereinafter, in order to fully understand the object, features and effects of the present application, with reference to the examples and drawings, the concept, specific structure and obtained technical effects of the present application will be accurately and completely described. As is obvious, the described examples are only some examples of the present application, not all examples. Based on the examples of the present application, other examples obtained by those skilled in the art without creative labor all belong to the scope protected by the present application. Also, all connection / connection relationships according to the present application do not mean only direct connection of members, but can constitute a better connection structure by adding or reducing connection auxiliary members according to the specific implementation situation. Each technical feature in the present application can be combined with each other as long as there is no contradiction.

[0016] As shown in FIG. 1, according to the present invention, a manufacturing system for a flexible foil material is provided. Specifically, the system includes a first liquid reservoir roller 10, a tension roller 20, a first conductive roller 30, and a second conductive roller 40 arranged in sequence along the transmission direction of the film 50. The film 50 passes through the first liquid reservoir roller 10, the tension roller 20, the first conductive roller 30, and the second conductive roller 40 in sequence, and the tension roller 20 and the second conductive roller 40 are in contact with the upper surface of the film 50, and the first conductive roller 30 is in contact with the lower surface of the film 50. Then, the first conductive roller 30 and the second conductive roller 40 conduct electricity to the upper and lower surfaces of the film 50.

[0017] In this embodiment, the horizontal height of the contact position where the film 50 contacts the tension roller 20 is greater than the horizontal height of the contact position where the film 50 contacts the first liquid reservoir roller 10. As shown in FIG. 1, the film 50 located between the first liquid reservoir roller 10 and the tension roller 20 forms an angle with the horizontal plane and warps upward along the direction of the tension roller 20. Thereby, it is possible to prevent the plating solution from reaching the first conductive roller 30 along the film 50 and plating copper on the first conductive roller 30 by an electric current.

[0018] Furthermore, the first conductive roller 30 and the second conductive roller 40 are connected by a conducting wire, so that the current of the first conductive roller 30 is equal to the current of the second conductive roller 40. For this reason, the voltages at both ends of the film 50 are equal, and even if there are minute holes in the film 50, no short circuit occurs and no burning phenomenon occurs.

[0019] Next, as shown in FIG. 1, according to the present invention, there is provided a manufacturing system for the flexible foil material according to a specific embodiment. The manufacturing system for the flexible foil material further includes a plating tank 60, a titanium basket 70, and a second liquid accumulating roller 80. The first liquid accumulating roller 10 and the second liquid accumulating roller 80 are located at both ends of the plating tank 60. The film 50 passes through the second liquid accumulating roller 80, the titanium basket 70, and the first liquid accumulating roller 10 in sequence within the plating tank 60. The first liquid accumulating roller 10 and the second liquid accumulating roller 80 have the same structure, and each includes two roller bodies with the same structure and arranged in parallel vertically. The film 50 passes between the two roller bodies. The titanium basket 70 is located in the plating solution of the plating tank 60. And copper balls are provided inside the titanium basket 70. The film 50 is located in the plating solution of the plating tank 60 and passes between adjacent titanium baskets 70.

[0020] Also, in the above embodiment, a liquid storage tank 90 is further provided below the plating tank 60, and the role of the liquid storage tank 90 is to circulate the plating solution. A speed adjustment roller 401 is provided behind the second conductive roller 40.

[0021] The wrap angle formed by the first conductive roller 30 and the film 50 is twice the wrap angle formed by the second conductive roller 40 and the film 50. Thereby, the arc length of the film corresponding to the wrap angle can be lengthened, and the contact area between the film 50 and the roller can be increased.

[0022] According to the above structure, the manufacturing system for the flexible foil material of the present application can greatly reduce the occurrence of copper plating on the conductive roller, avoid the crystallization of the plating solution on the conductive roller, prevent the crystal from penetrating the film 50, and improve the quality of the plated film product.

[0023] As described above, the preferred embodiments of the present application have been specifically described. However, the present application is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions as long as they do not violate the spirit of the present application. Any of these equivalent modifications or substitutions are included in the scope defined by the claims of the present application.

[0024] According to the manufacturing system of the flexible foil material of the present invention, the occurrence of copper plating on the conductive roller can be significantly reduced, the formation of plating solution crystals on the conductive roller can be avoided, the penetration of the film by the crystals can be prevented, and the quality of the plated film product can be improved. Therefore, the manufacturing system of the flexible foil material of the present invention has practicality.
