Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology for rolled copper foil, and in particular to a foil connector device for a surface treatment machine for rolled copper foil. Background Technology

[0002] Rolled copper foil is commonly used in flexible copper-clad laminates, printed circuit boards, mobile phone back panels, camera modules, and other fields. In order to enhance the surface roughness of rolled copper foil, improve the adhesion and peel strength between rolled copper foil and substrate, optimize electrical performance and prevent oxidation contamination, and meet the high requirements of high-end electronic products for copper foil materials, surface treatment machines are usually used to treat the rolled copper foil.

[0003] The surface treatment method for rolled copper foil mainly includes the following steps: pretreatment, surface roughening treatment, anti-oxidation treatment, functional coating, and drying. Pretreatment may include alkaline degreasing, acid pickling activation, and water washing; anti-oxidation treatment may include electroplating and passivation; and functional coating may include coupling agent treatment, etc. Figure 1 As shown, the surface treatment machine has multiple treatment tanks 510 to complete different surface treatment steps. Each treatment tank 510 includes an inlet roller 511, an underwater roller 512, and an outlet roller 513. The inlet end of the surface treatment machine is equipped with a conveyor roller 520, and the outlet end is equipped with an oven 530 and a take-up roller 540. When surface treating copper foil, the conveyor roller 520 conveys the rolled copper foil 600 into the treatment tank of the surface treatment machine, and after passing through multiple roller groups, it is wound up by the take-up roller 540.

[0004] However, because rolled copper foil is extremely thin and easily torn, the foil feeding process is time-consuming, labor-intensive, and wasteful of materials. Foil feeding refers to the process of conveying the head of the rolled copper foil through various processing tanks to the take-up roller.

[0005] Therefore, there is an urgent need to develop a foil-passing connector device for a copper foil surface treatment machine to improve foil-passing efficiency and reduce copper foil waste. Utility Model Content

[0006] In view of the above problems, this utility model is proposed to provide a foil-passing connector device for a rolled copper foil surface treatment machine that overcomes or at least partially solves the above problems, so as to solve the problems of difficult foil passing and excessive copper foil material waste in the existing rolled copper foil surface treatment.

[0007] Specifically, this utility model provides a foil connector device for a surface treatment machine for rolled copper foil, characterized in that it includes:

[0008] A clamping member, comprising two clamping parts, each clamping part comprising a flexible plate, the front ends of the two flexible plates being hinged together, the clamping member being used to clamp the two sides of the head of the copper foil;

[0009] A traction rope, the rear end of which is fixedly connected to the clamping member, is used to wind around the conveying roller, the roller group of each processing tank of the surface treatment machine and the take-up roller, so as to drive the clamping member and the copper foil to pass through the foil.

[0010] Optionally, the two flexible boards are arranged symmetrically;

[0011] Each of the aforementioned flexible boards has a thickness of 0.5 mm to 2 mm;

[0012] Each of the flexible boards is trapezoidal in shape, and the side length of the front end of each flexible board is smaller than the side length of its rear end.

[0013] Optionally, the clamping part further includes:

[0014] An adhesive layer is provided on the opposing surfaces of both flexible circuit boards, and the adhesive layer is used to bond and fix the copper foil.

[0015] Optionally, the clamping part further includes:

[0016] A metal plate, wherein the metal plate is disposed on the surface of the flexible plate or embedded in the interior of the flexible plate;

[0017] The metal plate is made of steel or aluminum;

[0018] The thickness of the metal plate is 0.1 to 0.5 mm.

[0019] Optionally, there are at least two traction ropes, and each traction rope is spaced apart along the width direction of the clamping member.

[0020] Optionally, the length of the traction rope is greater than or equal to 80m.

[0021] Optionally, the front ends of the two flexible boards are hinged together by a bent metal strip; or

[0022] The front ends of the two flexible boards are hinged together by plastic hinges.

[0023] Optionally, the traction rope is made of nylon or polyvinyl chloride.

[0024] Optionally, the two flexible plates are provided with mounting holes, and the traction rope is fixedly connected to the two flexible plates through the mounting holes.

[0025] Optionally, each of the flexible plates has a chamfered edge on the side away from the traction rope.

[0026] This invention relates to a foil-passing connector device. By incorporating a traction rope and clamping components, the device enables continuous foil passing operations for rolled copper foil. During the foil passing process, the precise guidance of the traction rope combined with the flexible contact of the clamping components reduces manual intervention and effectively eliminates copper foil misalignment and wrinkling issues common in traditional processes. This significantly shortens the time required for each foil passing operation and significantly improves foil passing efficiency. Furthermore, it reduces the copper foil scrap rate, thereby lowering the overall production cost of rolled copper foil.

[0038] Figure 2This is a schematic structural diagram of a foil connector device for a surface treatment machine for rolled copper foil 3 according to an embodiment of the present invention, as shown below. Figure 2 As shown, and refer to Figures 3 to 4 This utility model provides a foil-passing connector device for a surface treatment machine for rolled copper foil 3, including a clamping member and a traction rope 2. The clamping member includes two clamping parts 1, each clamping part 1 including a flexible plate 11. The front ends of the two flexible plates 11 are hinged together. The clamping member is used to clamp the two sides of the head of the copper foil 3 to fix and protect the copper foil 3. The rear end of the traction rope 2 is fixedly connected to the clamping member. The traction rope 2 is used to wind around the conveying roller, the roller group of each processing tank of the surface treatment machine, and the take-up roller to drive the clamping member and the copper foil 3 to pass through the foil.

[0039] The method of using the foil-passing connector is as follows: First, the front end of the traction rope 2 is passed sequentially through the conveyor roller, the roller group of each processing tank, and the take-up roller, so that the traction rope 2 is wound around the roller 4 of the conveyor roller, the roller group of each processing tank, and the take-up roller; then, the head of the copper foil 3 to be passed is clamped between two flexible plates 11 using the clamping device, and the copper foil 3 is fixed to the flexible plates 11 with adhesive; then, the conveyor roller, the roller group of each processing tank, and the take-up roller are started, and the rotation speed of each roller is synchronized by the PLC controller, so that the traction rope 2 drives the clamping device and the copper foil 3 to pass sequentially through each processing tank and be wound up by the take-up roller, thereby completing the foil-passing process of the copper foil 3. After the foil-passing is completed, the copper foil 3 is separated from the clamping device, and the foil-passing connector is separated from the take-up roller.

[0040] The foil-passing connector device of this embodiment has a simple structure and is easy to use, and it has the function of quickly guiding the copper foil 3. Using the foil-passing connector device of this embodiment, during the foil-passing process of the copper foil 3, on the one hand, under the guidance of the traction rope 2, manual intervention can be reduced, and the foil-passing time can be shortened from 45 minutes / roll in the prior art to 18 minutes / roll, thereby increasing the foil-passing efficiency by 60%. On the other hand, by using the flexible plate 11 to clamp the copper foil 3, creases at the head of the copper foil 3 can be avoided, and the yield rate can be increased from 92% to 98.5%. Each roll of copper foil 3 saves 3-5m of head waste, thereby greatly reducing the manufacturing cost of rolled copper foil products.

[0041] In some optional embodiments of this utility model, the flexible board 11 is made of plastic or rubber.

[0042] Preferably, the flexible sheet 11 is a PVC (polyvinyl chloride) plastic flexible sheet 11, which can withstand temperatures above 80°C. More preferably, the flexible sheet 11 is a transparent flexible sheet 11.

[0043] In some optional embodiments of this utility model, the thickness of each flexible board 11 is 0.5 mm to 2 mm. Preferably, the thickness of the flexible board 11 is 0.5 mm to 1 mm. For example, the thickness of the flexible board 11 is 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm or 1 mm.

[0044] like Figure 2 As shown, in some optional embodiments of this utility model, the two flexible boards 11 are symmetrically arranged. With the above arrangement, when clamping the copper foil 3, the contact area between the two flexible boards 11 and the copper foil 3 can be the same, which is more conducive to the copper foil 3 being subjected to uniform force and can further prevent damage to the copper foil 3.

[0045] In some optional embodiments of this utility model, each flexible board 11 is circular, square, or rectangular in shape.

[0046] like Figure 2 As shown, in some optional embodiments of this utility model, each flexible board 11 is trapezoidal in shape, and the side length of the front end of each flexible board 11 is smaller than the side length of its rear end. Preferably, the flexible board 11 is an isosceles trapezoid. Accordingly, as... Figure 5 As shown, the head of the copper foil 3 can be designed as a triangular structure or a trapezoidal structure.

[0047] In this embodiment, designing the flexible board 11 as a trapezoidal structure with a front side length smaller than the rear side length can produce the following beneficial effects: the narrow front side of the trapezoid can reduce fluid resistance when entering the processing tank and reduce load fluctuations of the traction rope 2. The wide rear side of the trapezoid can increase the contact area with the copper foil 3, disperse the shear stress during the traction process, and prevent the copper foil 3 from tearing due to stress concentration. The trapezoidal structure can also reduce turbulence, allowing the copper foil 3 to pass through more smoothly and reducing the impact of liquid on the copper foil 3, thereby protecting the copper foil 3 from damage.

[0048] like Figure 4 As shown, in some optional embodiments of this utility model, the clamping part 1 further includes an adhesive layer 13. An adhesive layer 13 is provided on the opposing surfaces of both flexible plates 11, and the adhesive layer 13 is used to bond and fix the copper foil 3. By providing the adhesive layer 13, the two sides of the copper foil 3 can be fixed to the inner wall surfaces of the two flexible plates 11 more quickly and conveniently.

[0049] like Figure 4 As shown, in some optional embodiments of the present invention, the clamping part 1 further includes a metal plate 12, which is embedded inside the flexible plate 11.

[0050] In some optional embodiments of the present invention, the clamping part 1 further includes a metal plate 12, which is disposed on the outer surface of the flexible plate 11.

[0051] In the two embodiments described above, the metal plate 12 can be made of steel or aluminum, which has high hardness and ductility. The thickness of the metal plate 12 is 0.1 to 0.5 mm (e.g., 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, or 0.5 mm). By providing the metal plate 12 inside or on the surface of the flexible plate 11, folding of the flexible plate 11 when it is attached to the surface of each roller group can be avoided, ensuring that the shape of the flexible plate 11 remains unchanged along the direction of the roller group during the movement process.

[0052] like Figure 2 and Figure 3 As shown, in some optional embodiments of this utility model, there are at least two traction ropes 2, and each traction rope 2 is spaced apart along the width direction of the clamping member. For example, there may be two or more traction ropes 2.

[0053] This embodiment, by setting multiple traction ropes 2, is more conducive to adjusting the traction direction and can effectively prevent the clamping part from shifting relative to the traction direction during the foil passage process.

[0054] In some optional embodiments of this utility model, the length of the traction rope 2 is greater than or equal to 80m. Specifically, the traction rope 2 should conform to the overall length of the surface treatment machine during operation, and its specific length can be selected according to the model of the surface treatment machine and the specific surface treatment process.

[0055] In some optional embodiments of this utility model, the front ends of the two flexible plates 11 are hinged together by heat fusion. Specifically, the edges of the two flexible plates 11 are heated to the surface melting using a heating device, and then the softened surfaces are pressed together with a small pressure to achieve connection.

[0056] In some alternative embodiments of this invention, the front ends of the two flexible boards 11 are connected together by a plastic hinge.

[0057] In some optional embodiments of this utility model, the front ends of the two flexible boards 11 are hinged together by a metal strip 14. Specifically, a bent metal strip 14 is used to fix one end of the metal strip 14 to the front end of one flexible board 11, and the other end of the metal strip 14 is fixedly connected to the front end of the other flexible board 11.

[0058] Furthermore, the metal strip 14 can be made of aluminum or steel.

[0059] In some optional embodiments of this utility model, the traction rope 2 is made of nylon or PVC (polyvinyl chloride). In this embodiment, the traction rope 2 has certain resistance to acid and alkali corrosion, which not only gives it a longer service life, but also prevents the traction rope 2 from chemically reacting with the bath solution in the treatment tank and contaminating the bath solution, thus affecting the subsequent surface treatment effect.

[0060] In some optional embodiments of this utility model, the two flexible plates 11 are provided with mounting holes, and the traction rope 2 is fixedly connected to the two flexible plates 11 through the mounting holes.

[0061] In this embodiment, the specific connection process between the traction rope 2 and the flexible plate 11 is as follows: the traction rope 2 is passed through the pre-set mounting holes on the two flexible plates 11, and the traction rope 2 is fixed to the flexible plate 11 by tying it together using the mounting holes to achieve the connection purpose. Alternatively, depending on actual needs and the characteristics of the flexible plate 11 material, other methods can be selected, such as using screws, nuts, or other fastening elements to firmly fix the rear end of the traction rope 2 to the two flexible plates 11 to ensure a stable and reliable connection.

[0062] In some alternative embodiments of this utility model, each flexible plate 11 has a chamfered edge on the side away from the traction rope 2.

[0063] In this embodiment, a chamfer is provided to prevent the edge of the flexible board 11 from scratching the copper foil 3.

[0064] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
